Both Google and Apple have struggled to get the majority of the smartphone market. And the career takes more than 5 years. When it comes to direct sales, Apple devices circle around Android devices. However, today, things have changed and the sales of Android devices are increasing. This is clearly due to the advantages that Android and Android applications offer. Let’s read more about this.

1. Open ecosystem

Unlike Apple, you can choose to download apps from a source other than the Google Play Store. This is the freedom that you cannot enjoy with an iOS phone or tablet. You can go to an application developer’s website and install any application from there. For example, you can download and install apps from F-Droid, Getjar, Appstore, and Amazon, just to name a few.

Of course, there is some risk in obtaining third-party applications, but you are not required to install applications from a single source. So, you have a choice here.

2. Cheaper apps

If you have a smartphone, you need apps to get the most out of your device. For iOS users, the apps may not be cheap. However, if you have Android, you can choose from millions of free apps. So, you don’t play anything for them. Also, even if you want to get paid apps, they are very cheap. On the other hand, iOS apps cost a minimum of 69p. So this is another advantage that you can enjoy if you go for this operating system.

3. Customizable UI

Since day one, Google engineers and developers have been working together to make Android as customizable as possible in the US As a result, you can see that the current operating system has tons of widgets that can be easily customized. You can put them anywhere in the user interface where you can access other things, like media feeds, calendar, and email, to name a few. Therefore, this addition makes it easy for you to adjust the user interface based on your professional needs.

4. Flexible

If you are an app developer and you want to put your app on the iOS app store, you need to submit your request. The company is very strict when it comes to installing software on its platform.

On the other hand, Android is open and offers Software Developer Kit (SDK) that works on many platforms. Therefore, it is easier for companies to develop applications and launch them on Android for users to download.

5.Support NFC

iOS is not NFC-enabled even though there is great potential for NFC. For example, this feature can help with cashless payment systems like Google Wallet, which encourages the use of a cashless society. Additionally, NFC can be used to automate tasks.

So, if you love to download and install new apps for free, we suggest that you choose an Android phone because Android offers all the benefits mentioned above. I hope this helps.

After a career break, returning to work can be challenging. Whatever the reason for career interruption, absence from work often leads to feelings of reduced confidence and uncertainty about your ability to perform a particular job.

If you are going back to work after, say, maternity leave and your job has been kept open to you, the transition will be somewhat easier than if you had lost your job entirely. When parents return to work after a career hiatus, they will generally find that getting back on track with their careers will be facilitated by their employer’s understanding and willingness to help them “get their kidneys back” again. As part of your return-to-work policy, they will usually assist you with a return-to-work interview, which is great for career returnees and helps you get back on track again.

However, if you lost your job through layoff or for another reason, especially if you’ve been absent from work for a significant period of time, returning to work can be more difficult.

It can be difficult to be optimistic about landing a new job, especially if you feel a little hurt or bruised after laying off, but even when you know you need to start, it can be difficult to do so.

You know you should be watching, but you don’t really feel committed to getting back to work.

You’ve given it a half-thought due to pressure from others, but at this point you don’t want to push it any further. Your confidence and motivation are being tested more severely. Deciding what you are qualified to apply for is the crucial issue now as it affects your entire approach to getting back to work.

When you’re ready to start actively looking for work, think about your skills and experience and start updating your CV or CV. You start a file to record your applications and other activities and rehearse what you need to say when your first interview arrives.

Recognize that it can be daunting and that your confidence may falter after the initial enthusiasm. You must learn not to get discouraged, as a lack of early success can lead to a loss of motivation; But perseverance, patience and perseverance will always pay off with the result you want.

Now. It all depends on you and your own sense of determination, but with the help of an expert, some things may become a lot easier. With a little guidance, you can achieve the return to work you want, and routes back to work after a career break or maternity leave can be easier if you have the right helpful information.

Let’s look at the 10 hottest AI apps that manage to harness tons of data in today’s changing environment.

SIRI
SIRI is one of the most famous artificial intelligence applications. It is a personal assistant software for Apple devices, including iPhone, iPad, iPod Touch, Apple Watch, and AppleTV, which works as a smart knowledge guide for recommending, answering questions, and delegating requests to other connected web services. The software is voice controlled and therefore returns individualized responses that are learned from the user’s language. According to Apple’s senior vice president of software engineering Craig Federighi, Siri receives 1 billion requests a week. As of 2016, Siri is available in 20 languages.

GOOGLE NOW
Another smart personal assistant is Google Now developed by Google, which is part of the Google application available for Android and iOS. To enable Google Now, you must start the Google application and then allow Google to pull all the synchronized information from all the Google services you use and your location history to make recommendations and alerts to you. By disabling all the necessary privacy and tracking settings in this probably the most practical AI app, a user can view different Google Now cards: activity summary (steps you’ve taken to stay in shape), boarding pass (sent to Gmail account), shown later at the airport), Events (events scheduled in your Google Calendar), Flights (your flight status in real time), Location Reminders, Parking Location (helps find your parked car), Translation (look up word translations), TV (a list of programs broadcast in real time) and many others. All the commands in Google Now can be controlled by voice, however, they are limited. Google Now is currently available in English and is a major competitor to Siri.

CORTANA
Cortana is Microsoft’s smart personal assistant INITIALLY designed for Windows Phone, the target is now available on Android, Windows 10, xBox One, and it’s Apple’s iOS. Cortana software reacts to a user’s voice and performs limited commands, answers questions using information from the installed browser (Bing by default), works as a secretary scheduling events, locating necessary files, and opening necessary applications. The Cortana artificial intelligence app can process voice commands in English, German, Spanish, Italian, French, Chinese, Portuguese, and Japanese.

ALEXA
Alexa is the voice service created by Amazon for the Amazon Echo smart speaker, which was widely introduced in 2015. Alexa uses natural language processing algorithms to adapt to the user’s natural voice. Plus, because it’s built into the cloud, Alexa is constantly learning by recognizing patterns of user interactions. The more a user interacts with Alexa, the more it evolves and becomes smarter, providing higher quality answers to a user’s questions. The Alexa AI Implementation – Has a free SDK that developers can use to establish new voice-based AI software and devices.

KINECT
Kinect is an AI-based motion controller and motion detection technology used by Microsoft That Is on Xbox One and Xbox 360 game consoles. Kinect analyzes the natural user interface and reacts to voice commands and gestures. Microsoft offers a free SDK for developers to create Kinect-enabled applications. This has already resulted in a wider application of Kinect technology for non-gaming purposes, including healthcare, retail, military, and robotics.

BRAIN
Braina is a free artificial intelligence application that works as a personal productivity software and a virtual office assistant on Windows computers. The software reacts to a user’s voice commands and performs different tasks on your computer accordingly. Due to the built-in voice recognition technology, the user can interact with their computer remotely via Wi-Fi through the Braina Android app. Braina is currently available in English, free and paid versions.

VIV
VIV is more than an artificial intelligence app, but an artificial intelligence platform from the creators of Siri. Unlike Siri, VIV has an open platform that allows developers to create external plugins to work with. The creators of VIV claim to be the first ever ubiquitous, consumer-oriented assistant. Work on it began in 2012. The demo version of the ‘smart interface for everything’ was presented by VIV CEO Dag Kittlaus at TechCrunch Disrupt NY in May 2016.

PAN
PAN is a free artificial intelligence software that analyzes virtually any type of textual data, such as poetry, fiction, history, newspaper, etc. The application first analyzes the text, recognizes the structure of your sentences, the mood and the tone of the given text. PAN generally allows to put any text under a microscope and eventually provide different variations of its understanding based on a comprehensive analysis performed.

WIPRO HOLMES
Wipro HOLMES is a cognitive artificial intelligence platform used for the development of predictive systems, visual computing applications, digital virtual agents, automation of cognitive processes, knowledge visualization, drones and robotics. Wipro HOLMES learns from new information and can make recommendations as well as predict failures. The platform was designed and introduced in 2016 by the Indian company Wipro to optimize business processes in corporations.

WOLFRAM ALPHA
Wolfram Alpha is a free intelligent response engine, which uses artificial intelligence to provide answers to a user’s question from a selected data set such as statistics, cross-source checking, expert reviews, etc. Wolfram Alpha differs from semantic search engines like Google in the way that it provides specific answers from a structured set of information instead of matching the question to the best answer by indexing multiple answers to that question. Wolfram Alpha is being used to respond to some requests from Apple’s Bing, DuckDuckGo, and even Siri. The Wolfram Alpha app is available for iOS and Android, Kindle Fire, Nook.

CONCLUSION

Artificial intelligence is undoubtedly a very powerful tool for creating experiences never before imagined. We hope that the artificial intelligence applications entering our lives will continue to serve humanity in the most beneficial way.

In Bioshock Infinite, Booker Dewitt is narrated as a guy who always feels guilty and depressed about all his mistakes in the past. Driven by the need to erase his debts and get out of all his troubles, Booker makes such a horrible decision in his life. He sells his little daughter, Anne Dewitt, to a guy named Robert Lutece, who is under the command of Comstock.

After reluctantly selling her son to Robert Lutece, she changes her mind and chases Robert down the hall to cancel the deal with Comstock and get her daughter back. Unfortunately, as shown in the Bioshock Infinite cutscenes, Booker fails to wrest his son from Comstock’s hands. When Lutece’s time machine window closes, Anne’s little finger is cut into two parts in 2 different realities, in Booker’s reality and Comstock’s reality in Columbia.

Booker Dewitt’s past

Well, if you have already played this game, either on PC or console, then you also know that in Bioshock Infinite, Booker is characterized as a guy who is full of rage, especially when it comes to his past, where he committed so many brutal actions during his tenure as a soldier. As shown in the game, Booker used to be part of the 7th Cavalry Regiment of the United States Army as a soldier and was seriously involved in a war called “The Wounded Knee Battle”.

During that war, Booker had committed many brutal, even inhuman acts on many of his enemies, such as skinning their heads and burning them all together. That is why one of his comrades, Cornelius Slate, called Booker “The White Indian”, thanks to his brutal methods of killing enemies in war.

Shortly after the entire war ended in 1892, when Booker was still 18 years old, his wife / girlfriend gave Booker a baby boy named Anne Dewitt. Sadly, after giving birth to Anne, his wife died. And this is the part where Booker’s problems start to creep up on his shoulders.

Realizing that he had become a single father, raising his daughter alone, not to mention all the brutal acts he committed during the war, Booker felt really depressed, so he decided to turn to alcohol and gambling. And obviously alcohol and gambling just didn’t mix very well for him. So, as a drunk gamer, you lost a lot of your money and started collecting a lot of debts, a lot of debts.

And that is not the end. When he finally became an agent for the Pinkerton National Detective Agency, Booker apparently still carried all the brutal habits from his past and implemented them as methods for his actions as an agent for Pinkerton. And because of that, his agency fired him because he was too cruel as an agent.

When Booker sells his daughter to Comstock

As time passed and Booker Dewitt continued to get carried away by gambling and alcohol much more deeply than before, he began to earn debt for his loss as a “drunk gamer.” Realizing that his debts continued to pile up and that he was unwilling to allow his daughter, Anne Dewitt, to live in her miserable life, Booker met with a guy named Robert Lutece, a scientist Comstock ordered to meet Booker.

Thanks to the time machine and the reality of Rosalind Lutece, Robert apparently knew that Booker had a lot of debts on his side, so Robert offered him the golden opportunity to erase all of Booker’s debts with the exchange of his little daughter, Anne Dewitt. .

And as shown in the game’s scenes, Booker reluctantly accepted that offer, but soon changed his mind and decided to chase Robert down the hall to cancel the deal.

Booker decides to get baptized to wash away his sins

With Anne Dewitt brought by Comstock to Columbia, Booker felt genuinely guilty about his mistake in selling his daughter, not to mention all the other problems he had had before, such as brutal actions during the war, gambling, drinking alcohol, collecting money. debts. , and many more. So, Booker decided to take baptism as the only way to wash away all his sins in the past and start a new, better life. This is the part where the story gets the most interesting.

Booker rejects or accepts baptism

• At the moment when Booker is still deciding whether to ACCEPT baptism or REFUSE baptism, this reality is divided into 2 different realities.
• In the FIRST reality or let’s call it “TIMELINE A”, Booker decides to ACCEPT the baptism and that’s when he changes his name and becomes Comstock.
• On the other hand, in the SECOND reality or “TIMELINE B”, Booker apparently feels that all sins simply cannot be washed away by that baptism, so he decides to REFUSE the baptism and remains as Booker Dewitt.

It is worth noting that the actual reality that needs to be underlined in this game is “TIMELINE B” or the reality in which Booker REFUSES baptism and remains himself. However, the fact that there is another reality, where Booker decides to ACCEPT baptism and becomes Comstock, then it is also important to know who Comstock really is.

Who is Comstock?

Well now you know that in this game, Booker will convert or change his name to Comstock if he decides to ACCEPT baptism. In this reality or as previously mentioned as “TIMELINE A”, Comstock apparently feels and believes that all his sins in the past, such as committing brutal actions during the war, gambling, drinking alcohol, collecting debts, selling his daughter, etc. be washed with baptism.

However, despite being born a new better person, Comstock apparently still inherits all of his dark side from his past as Booker Dewitt. After successfully convincing the New York government to help fund the tech projects and inventions of her friend, Rosalind Lutece, Comstock succeeds in making her dreams come true. And that is building a floating city of Columbia and becoming a leader or “prophet” to the people of Columbia.

What is Booker’s mission at Columbia?

In 1912, Booker met Robert Lutece again for the second time. However, this time, Robert was not alone as he also dragged his “twin”, Rosalind Lutece to meet Booker. In this part, Robert and Rosalind offered Booker a job to help a girl named Elizabeth escape Columbia and bring her to New York unharmed.

After being dragged into the reality where Columbia exists (from “TIMELINE B” to “TIMELINE A”), Booker suddenly had some memories mixed in his mind and he remembered them again with his past, but mixed with new memories. ” old “at Columbia (when Booker became Comstock, because Booker is basically the same person as Comstock). So when he was offered a job to get a girl to take her to New York to “ELIMINATE HER DEBTS,” Booker simply nodded and didn’t question that job.

Who is Elizabeth?

Elizabeth is a girl who has been held captive in the Monument Island tower by Comstock. After being “caged” for almost the rest of her life in a tower, Elizabeth educates herself with so many books and knowledge on how to open locks and geometric coordinates, while sharpening her power to open tears, her “super power” (as Spiderman with his “web”, Superman with his “vision” or Batman with his “big bank account”). He then meets Booker for the first time after Booker falls from the top of Monument Island into the library.

Booker’s main strengths

In Bioshock Infinite, Booker Dewitt has so many strengths to accompany him throughout his journey in Columbia, in the form of weapons and telekinesis powers. Most of their weapons are old-fashioned 1900 pistols such as cowboy pistol, old school shotgun, and many more.

In addition to those tangible weapons, Booker Dewitt is also blessed with some telekinesis powers that allow him to use some kind of superpowers from his hands to fight enemies that stand in his way. To name a few, there are some prominent telekinesis powers that Booker possesses, such as the one called “Devil’s Kiss”, which can be used by Booker to throw a fire grenade at enemies. He can also use his other telekinesis superpower called “Possessions”, which can turn his enemies into his allies, but not permanently.

On some occasions, Elizabeth also helps Booker Dewitt a lot with his power to open tears, allowing him to transport some things (for example, doctors, bullets, walls to defend, cargo, etc.) from other realities than reality. by Booker. . Sometimes Elizabeth also gives Booker some gold coins or things to protect her from enemies.

When Booker realizes that Comstock is actually himself

In the final part of this game, Booker finally discovers that, all along, Comstock is actually himself, but from “TIMELINE A” or the reality in which Booker decides to ACCEPT baptism. Having known that, he and Elizabeth realize that Comstock cannot be stopped because he already masters all realities, thanks to Lutece’s reality and time machine. So even though Booker manages to kill Comstock by smashing his head against the edge of the fountain and drowning him in water, Comstock will still be alive in many different realities.

The best way to prevent Comstock from re-living in all the different realities is to prevent it from being born in the first place. And the first time Comstock was born or created was when Booker decided to ACCEPT baptism. Therefore, Elizabeth opens the tear and brings Booker to the exact reality while he is still being baptized in the river.

In this reality, Booker finally realizes that the only way to prevent Comstock from being born is none other than to kill Booker himself in the river. Elizabeth then, along with the other Elizabeths (plural) from different realities, gather around Booker and drown him in water until he is killed.

And finally, in the final story of this game, Booker Dewitt finds himself alive again in the reality where he is still in his own home. However, Anne Dewitt’s existence in her room remains a mystery until now, as Irrational Games decides to end the game shortly after Booker opens the door to Anne’s room.

Would you like to make a profit online? You can do it with diligent work and diligence. If you currently have a website and need to take advantage of it, then one of the less demanding online cash opportunities you can research is the pay per click promotion.

The most famous and notable pay per click that the open door promotes is Google AdSense. When you sign up for a Google AdSense account, you will be able to put content and image standards on your websites, and when a guest clicks on those writings and flags, you will get cash. Simple huh?

By using AdSense, you can also ensure that the ads displayed on your website are applicable to your content.

The idea is simple, however, you must also realize that to be fruitful in AdSense is that you must have the ability to reliably drive movement to your site, and I mean a gigantic activity.

The most ideal approach to increasing huge and focused on activity is to use the magic words of privilege. To do this you have to conduct an exploration. There are numerous free devices available online for decisive word examination and one of them is also provided by Google, which is Google Trends. Google Trends will accurately reveal the trending slogans in any particular district.

An alternative system frequently used by the successful AdSense distributor is not to keep featured websites, but even dozens and several websites. To do this effectively, you need to establish a gradual focus on the number of websites you need to manufacture within a month.

With the presence of WordPress, Blogger and Joomla, making ten websites a week is not a problem. In the event that you can create ten websites per week, you will have 40 websites in a month and 480 websites in a year, that’s about 500 of the salary streams that open the doors for you!

In case you think that it will be difficult to create a lot of websites without anyone else, you can simply outsource, but this will force you into a touch of adventure.

In this regard, I trust that this reading will help you understand the idea of ​​profiting from the web using distributed pay-per-click open doors and the fundamental idea to achieve fruitful results.

While this strategy is more suitable for beginners, others may consider it as well.

What is the confusion about RAM?

Most computer users do a little research before upgrading their system to find out exactly about a perfect combination of CPU, motherboard, and video card that will meet all of their needs. But most of them fail when it comes to RAM. They only know the size of the RAM, that is, 1GB, 2GB or 4GB, but they do not know what this DDR1, DDR2 or DDR3 is about. So that’s why I came up with an idiotic guide to buying a RAM, because it turns out that selecting the proper DDR variant is a very important factor in determining how your system will perform overall, so all computer users should be fine. informed to learn. that.

DDR1 Specifications

DDR-DIM (Double Data Rate DIMM or DDR DIMM) or, more popularly, Single DDR. Dual data rate interfaces provide two data transfers per differential clock. Data is recorded when CK rises [the + side]y / CK low [the – side]. DDR1 uses the JEDEC standard for double date rate [DDR I] SDRAM. Like all DDR RAM, it is available as registered or unbuffered. Registered DIMMs are generally known as FB-DIMMs and have their address and control lines buffered to reduce signal load. FB-DIMMs are considerably more expensive than unbuffered DIMMs and are generally reserved for server use. There are very few enthusiasts / prosumers / gamers who use FB-DIMMs in their CPUs. Unbuffered DIMMs do not have address lines or control line buffers, so they cost significantly less. However, they can be limited by system load and are therefore generally restricted in the number that can be installed on a system. You will find that most unbuffered DIMMs these days can only be installed on one motherboard up to a maximum of 4 x 1 GB. Registered or buffered DIMMs do not have these limitations, and server boards can accommodate 8 x 1 GB, 16 x 1 GB, or more. An interesting and largely unknown aspect of unbuffered DDR DIMMs is that they can operate a faster clock cycle than FB-DIMMs.

DDR2 Specifications

DDR2 memory is the second generation of DDR memory. DDR2 starts with 400MHz speed level as the lowest available, while 400MHz speed is actually the highest speed for DDR1. Therefore, DDR2 picks up where DDR1 ends. It’s a bit strange, but due to different latencies, a 400MHz DDR1 will outperform a 400MHz DDR2, but the advantage returns to DDR2 as soon as the speed reaches the next step of 532MHz, which DDR1 cannot reach.

DDR3 Specifications

DDR3 is the third generation in DDR memory. DDR3 starts with a lower capacity level of 800 Mbps and goes up to 1600 Mbps with a bus speed of up to 2000 MHz. The biggest benefit with lower power consumption is the biggest benefit, as the operating voltage is only 1.5V for DDR3 compared to 1.8V for DDR2. Less heat is generated, which means systems will run cooler. Ultimately, the new technology will result in higher capacity modules: modules up to 8 GB (with 4 Gb chips) to help reduce server / workstation system costs.

Transfer fees

Another confusion is that RAM is primarily concerned with number of PCs, so here are the Transfer Rates for the various DDRs:

DDR1 transfer rate

DDR SDRAM: Double Data Rate SDRAM (DDR200, DDR266, DDR333 are standard) PC1600 (DDR-200 SDRAM); Clock speed: 100 MHz, data rate: 200 MHz, performance 1600 MB / s PC2100 (DDR-266 SDRAM); Clock speed: 133 MHz, data rate: 266 MHz, performance 2100 MB / s PC2400 (DDR-300 SDRAM); Clock speed: 150 MHz, data rate: 300 MHz, throughput 2400 MB / s PC2700 (DDR-333 SDRAM); Clock Speed: 166MHz, Data Rate: 333MHz, Performance 2600MB / s PC3000 (DDR-366 SDRAM); Clock speed: 183 MHz, data rate: 366 MHz, performance 2900 MB / s PC3200 (DDR-400 SDRAM); Clock speed: 200 MHz, data rate: 400 MHz, throughput 3200 MB / s

DDR2 transfer rate

DDR2 SDRAM: Double Data Rate SDRAM II (Quad Edge Clock, 1.8V Signaling), PC2-3200 Second Generation (DDR2-400 SDRAM); Clock speed: 100 MHz, data rate: 400 MHz, performance 3200 MB / s PC2-4300 (DDR2-533 SDRAM); Clock speed: 133 MHz, data rate: 532 MHz, performance 4300 MB / s PC2-5300 (DDR2-667 SDRAM); Clock speed: 167 MHz, data rate: 667 MHz, performance 5300 MB / s PC2-5400 (DDR2-675 SDRAM); Clock Speed: 167MHz, Data Rate: 667MHz, Performance 5400MB / s PC2-6400 (DDR2-800 SDRAM); Clock speed: 200 MHz, data rate: 800 MHz, throughput 6400 MB / s

DDR3 transfer rate

DDR3 SDRAM: Double data rate SDRAM III (four edge clock frequency, 1.5v signaling), 3rd generation PC3-6400 (DDR3-800 SDRAM); Clock speed: 100 MHz, data rate: 800 MHz, performance 6.40 GB / s PC3-8500 (DDR3-1066 SDRAM); Clock speed: 133 MHz, data rate: 1066 MHz, performance 8.53 GB / s PC3-10600 (DDR3-1333 SDRAM); Clock Speed: 166MHz, Data Rate: 1333MHz, Performance 10.67GB / s PC3-12800 (DDR3-1600 SDRAM); Clock Speed: 200 MHz, Data Rate: 1600 MHz, Throughput 12.80 GB / s
Now it will be very difficult to list which RAM is best suited to which motherboard. Before purchasing RAM, you should research your CPU manufacturer’s RAM recommendations and put that exact type of DDR in it. It would be just as silly to use a PC3-12800 DDR3-1600 with an AMD Sempron 2800+ as it would be to charge your Intel QX6800 with a PC1600 DDR-200. Each CPU / chipset combination has its proper DDR setting, and you need to figure out exactly what they are and stick with them. Triggering slower than recommended DDR on your system will kill critical RAM functions and could slow down your system.

Major Manufacturers

Here is the list of some of the main ones, as buying a RAM from an unknown vendor would end in warranty problems.

Kingston

Privateer

Patchwork quilt

Crucial

OCZ

Patriot

By following these guidelines and thoroughly researching the right DDR for your system, you will enjoy years of fast, trouble-free computing. A little study is a small price to pay!

I recently saw my co-worker disassemble a computer using a single tool. Was it the right tool for the job? Yes and no. It was the tool I had … it worked, however, there is definitely more than one tool that would have made the task easier! Definitely, many fiber optic installers know this situation very well. As a reminder, how many of you have used your splicer tool kit (cable knife / scissors) to remove the sheathing or even cut a protection tube and then use the scissors to cut the Kevlar? Did you touch the glass? Accidentally cut the glass and had to start over?

Properly splicing and terminating fiber optic cable requires special tools and techniques. Training is important and there are many excellent sources of training available. Don’t mix your power tools with your fiber tools. Use the right tool for the job! Being proficient in fiber work will become increasingly necessary as the importance of data rates, fiber to the home, and fiber to facilities continue to increase.

Many factors distinguish fiber installations from traditional electrical projects. Fiber optic glass is very brittle; Its nominal outside diameter is 125um. The slightest scratch, mark or even speck of dirt will affect the transmission of the light, degrading the signal. Safety is important because you are working with glass that can dig into your skin without being seen by the human eye. Transmission grade lasers are very dangerous and require protective goggles to be a must. This industry has been primarily concerned with voice and data grade circuitry that could tolerate some signal disruption or slowdown. The person speaking was repeated, or the data was relayed. Today we are dealing with IPTV signals and clients that will not tolerate pixelization or momentary image blocking. All the mentioned situations are reason for the client to look for another carrier. Every situation could have been avoided if due attention had been paid to the techniques used in preparing, installing and maintaining fiber optic cables.

With that said, why don’t we review the basic fiber preparation? Wire strippers are used to remove the 1.6 – 3.0mm PVC outer jacket on single and duplex fiber cables. The serrated kevlar cutters will cut and trim the kevlar resistance member directly under the cover and the tampon spacers will remove the acrylate (buffer) layer from the bare glass. A protective plastic layer is applied to the bare fiber after the drawing process, but before it is wound. The most common coating is a UV-cured acrylate, which is applied in two coats, resulting in a nominal outside diameter of 250um for the coated fiber. The coating is highly engineered, provides protection against physical damage caused by environmental elements, such as extreme temperatures and humidity, exposure to chemicals, stress points … etc. while minimizing optical loss. Without it, the manufacturer could not wind the fiber without breaking it. 250um coated fiber is the basic component of many common fiber optic cable constructions. It is often used as is, especially when no additional mechanical or environmental protection is required, such as inside optical devices or splice closures. For added physical protection and ease of handling, a secondary layer of polyvinyl chloride (PVC) or Hytrel (a thermoplastic elastomer that has desirable characteristics for use as a secondary shock absorber) is extruded over the 250um coated fiber, increasing the outside diameter up to 900um. This type of construction is known as “tight damping fiber.” Tight Buffered can be single fiber or multi fiber and are seen in local networks and indoor applications. Tight-damped multi-fiber cables are often used for applications within buildings, elevators, general buildings, and plenums.

‘Loose tube fiber’ generally consists of a bundle of fibers encased in a thermoplastic tube known as a buffer tube, which has an inside diameter that is slightly larger than the diameter of the fiber. Loose tube fiber has a space for the fibers to expand. Under certain weather conditions, a fiber can expand and then shrink over and over again or it can be exposed to water. Fiber cables sometimes have ‘gel’ in this cavity (or gap) and others that are labeled ‘dry block’. You will find many loose tube fibers in outdoor plant settings. The modular design of loose tube cables typically supports up to 12 fibers per shield tube with a maximum number of fibers per cable of more than 200 fibers. Loose tube cables can be fully dielectric or optionally shielded. Shielding is used to protect the cable from rodents such as squirrels or beavers, or from protruding rocks in a buried environment. The modular design of the buffer tube also allows for easy drop of fiber bundles at intermediate points, without interfering with other protected buffer tubes heading to other locations. The loose tube design also aids in the identification and management of fibers in the system. When there is protective gel, you will need a cleansing gel such as D-Gel. Each fiber will be cleaned with the 99% alcohol and gel cleaner. Cleanroom wipers (Kim Wipes) are a good choice to use with the cleaning agent. The fibers within a loose tube gel filled cable generally have a 250 um coating, so they are more brittle than a tight damping fiber. Industry standard color coding is also used to identify the buffers, as well as the fibers in the buffers.

A ‘rotary tool’ or ‘cable cutter’ can be used to cut a ring around and through the outer sheath of ‘loose tube fiber’. Once you expose the durable inner buffer tube, you can use a ‘Universal Fiber Access Tool’ which is made for a single central buffer tube inlet. Used on the same principle as the mid-span access tool (which allows access to the tight, multi-colored buffer coated damping fibers), the double blades cut the tube lengthwise, exposing the buffer coated fibers. Fiber manipulation tools such as a putty knife or pick will help the installer access the fiber that needs to be tested or repaired. Once the damaged fiber is exposed, a hand tool will be used to remove the 250um coating to work with the bare fiber. The next step will be to clean the end of the fiber and prepare it for cutting. A good cut is one of the most important factors in producing low loss in a splice or termination. A fiber optic cutter is a multipurpose tool that measures the distance from the end of the protective coating to the point where the glass will be joined and precisely cuts the glass. Always remember to use a fiber trash can for pieces of glass cut from fiber cable.

When performing a fusion splice, you will need a fusion splicer, fusion splice protection sleeves, isopropyl alcohol, and stripping tools. If you are using a mechanical splice, you will need stripping tools, mechanical splices, isopropyl alcohol, and a mechanical splice assembly tool. When hand finishing a fiber you will need 99% isopropyl alcohol, epoxy / adhesive, syringe and needle, polishing film (lapping), polishing pad, polishing disc, crimping tool, stripping tools , fiber optic connectors (or splices in connectors) and piano wire.

When a termination is completed, you must inspect the end of the connector with a fiber optic inspection microscope. By ensuring that light passes through the splice or connection, a visual fault locator can be used. This equipment will fire a visible laser down the fiber cable so you can tell that there are no breaks or bad splices. If the laser light stops the fiber somewhere, the glass will most likely break at that point. When more than one light is off at the connector point, the termination was not done correctly. The light must also pass through the fusion splice, if it doesn’t, stop and re-splice or terminate.

Over the years, popular life, mind, and Twitter, the 140 character or less casting site, has continued to evolve. First, it all started as a “texting the internet” site in the pre-“smart” smartphone era. Around 2009-2010, Twitter became a popular app that made it easy for people to let us know how their sandwich was doing or how great a workout they had done, even when we didn’t want to hear it. During that time, people were more likely to reply to a tweet or retweet it just to show how much they cared or didn’t care. Then in the last year or so, Twitter rolled out a new feature: bookmark.

In today’s fast-paced world, sometimes bookmarking a tweet seems easier some days. All you have to do is click on the little “star” icon and you’re on your way. However, what good is it? No one else other than the tweeter can see that you have bookmarked your tweet. You do not open it for your followers to send it to theirs, etc. Kill a tweet. It falls like a rock into a pond. If followers of original people don’t see it right away, then what’s the use of a “favorite”?

So which is the best option: reply or retweet? Well honestly, a retweet not only increases the original presence of tweeters on Twitter, it also has the potential to increase your presence. A retweet can do many different things. First, you can show emotion in the form of happiness because the tweet in question may have made you laugh, smile, or just feel like someone else might benefit from seeing it. Second, it can help a growing business grow faster.

When someone retweets a link, they link back to the website that was originally tweeted. Lastly, it gives you a better chance of getting more followers you didn’t know or couldn’t find before. A retweet is like putting your work on the bulletin board in elementary school. It’s there for everyone to see when they walk past it, even if they don’t actually know you.

One of the favorites is literally the gold star. You know it’s there, but no one else knows. You care that you got one, but no one else does.

So what about the answers? What are they for in the whole Twitter scheme? In fact, they serve as a direct connection between a tweeter and a tweetee. You can “personally” praise something or ask a question without negative ramifications. If you didn’t completely like what the tweet said, you can just reply and in the thread of the conversation, people can still find the link, giving the original tweet its due. It doesn’t work in the same way as a retweet, but it can have similar effects.

In general, Twitter is controlled by the user. They decide whether or not they want to do any of these three things. However, as an avid Twitter user, people should be urged to retweet links more than anything else. Help your fellow tweeters out and retweet your news to your followers. Even if not everyone wants that information, you are still giving others the option to follow the link or not.

So get out there and tweet. There are only 140 characters to express your opinion.

The early summers generally provide pleasant relief from chilling winters, but in April and May, the summer heat begins to take its toll, both physically and mentally. And when it’s a tropical climate, as in most of India, hot days can be stressful. People’s energy levels drop and so does their productivity.

This is when modern air conditioning arrives as a gift from God. A not very big. Offices, laboratories, hotels, public buildings today are equipped with air conditioning systems. Centralized air conditioning systems ensure cooling in every corner of the workspace.

While this all sounds good, it is not. Extensive air conditioning is synonymous with high energy consumption (and waste) that leads not only to high electricity bills, but also to the dreaded frequent power outages. The next step is, of course, the DG equipment, to provide the desired comfort indoors, while spewing clouds of black smoke with terribly high levels of noise pollution for the outside world and the environment to bear.

In the midst of saving ourselves from the fury of nature, we are inadvertently attacking nature more and more, which keeps returning even more furiously from time to time. Therefore, one of the biggest points of concern is the imminent danger from rising global temperatures (global warming!). So what will we do to survive and survive in comfort?

Let’s not forget that we have an immense source of energy in the same Sun from which we are protecting ourselves. One answer is power generation using energy from the sun. It’s free and for now we can safely assume, unlimited. Yes, solar energy can light our homes and cook our food. But can it also cool our houses? The answer again is yes. Solar air conditioning, a revolutionary and forthcoming technology, provides the answer.

Solar air conditioning refers to any air conditioning (refrigeration) system that uses solar energy. A liquid or gaseous substance accumulates on the surface of a solid and porous substance (adsorption) or is absorbed by a liquid or solid substance (absorption to provide the necessary cooling). In some processes, the supply air is directly conditioned, that is, it is treated in terms of temperature and humidity.

This thermally driven cooling and air conditioning process is at the heart of every solar cooling system. The main principle of sorption assisted air conditioning is shown in the graph here. Solar energy is used to dehumidify the sorbent.

This is a 9 stage process. In Stage 1 to 2, dehumidification by absorption of the outside air takes place with a simultaneous increase in temperature through the released heat of adsorption. The air is then cooled in the heat recovery rotor countercurrent to the exhaust air (stage 2 to 3). The air is cooled further (Stage 3 to 4) by evaporation-humidification; Therefore, the air inlet to the building has a lower temperature and less water vapor than the outside air. In stages 4 to 5 the air is heated and, if necessary, steam is added. Then, during stage 6, the temperature of the building’s exhaust air is lowered by evaporative cooling in the humidifier. This exhaust air is heated (stages 6 to 7) in countercurrent to the air inlet in the heat recovery rotor. The exhaust air is further heated (Stage 7 to 8) through external heat sources (i.e. solar thermal system). Finally, in stages 8 to 9, the sorption rotor is regenerated by desorbing the bound water.

Open and closed cycle air conditioning systems:

Open loop systems are most beneficial in buildings with high humidity loads and high air exchange rates. Installation of ducts for air supply and return air is required, as well as a heat recovery unit. In this, the outside air is dehumidified by sorption and then brought to the desired temperature by heat recovery, as well as direct and indirect evaporative cooling. Dehumidification is generally achieved in a rotor containing the desiccant material silica gel or lithium chloride, but more and more liquid desiccants (desiccant material: lithium chloride) are being tested. In these systems, solar heat is necessary for the regeneration of the absorption / adsorption unit.

Closed cycle evaporative cooling systems with desiccant are based on the processes of Adsorption (based on solid desiccants such as silica gel or zeolites with water as a refrigerant) or Absorption (where the desiccants are liquids, eg Pairs of materials of lithium bromide as a desiccant and water as a coolant, or water as a desiccant and ammonia as a coolant, where sub-zero temperatures may be required).

For cooling and acclimatization of buildings, onlythermally driven processes are used.

In practice, solar collectors are used to convert solar radiation into heat which is then fed to a thermally driven cooling process or direct air conditioning process. Particularly in special applications, for example to cool medicines in remote areas that are not connected to the grid, a photovoltaic generator transforms solar radiation into solar energy that then drives a refrigeration process, usually in the form of a compression cooler.

There have been considerable advances in the field of solar assisted heating and cooling and this technology is being rapidly tested and adopted around the world.

Recently, Solar Thermal World Magazine reported that India’s latest and probably largest solar thermal based air conditioning system came into operation at Muni Seva Ashram (MSA) in Goraj, located in the Vadodara district of Gujarat state in western India. A total of 100 parabolic dishes (Scheffler type) from the Indian company Gadhia Solar Energy Systems (GSES), each 12.5 m2 in size, now supply the 160-bed hospital’s already existing 100-ton air conditioning system in Muni Seva Ashram. .

Solar air conditioning performance

When designing a SAC system and to judge its performance, the key points to look at are the load profile, outside temperatures, and humidity.

The decision of whether solar cooling is sensitive is highly dependent on the load profile. Solar irradiation and cooling demand must be correlated, as the use of fossil fuels for chiller operation is disadvantageous from a primary energy point of view and should be avoided.

To achieve the highest degree of utilization possible, applications that also require heat to heat water or for the heating system outside of the cooling season should be explored. Therefore, residential buildings and small office buildings are best suited. If year-round cooling is required (process cold, server rooms), the solar cooling system can simply be used as a fuel saver for conventional air conditioning. In such a case, free cooling directly through the heat rejection unit could be an option in colder seasons.

The heat rejection rate greatly affects the performance and efficiency of the cooler. In most systems, waste heat is released into the environment via dry coolers or wet cooling towers. The former are suitable for areas with a moderate climate that only occasionally have high outside temperatures (> 30 ° C). Wet cooling towers have the advantage that cooling water temperatures can be obtained below ambient temperature. However, it only works if the high relative humidity allows evaporative cooling. In regions with water scarcity it is also not suitable. In addition, some countries have imposed strict hygiene regulations on wet cooling towers that make the operation of small systems economically unfeasible.

It is essential to take into account the fact that boundary conditions other than nominal conditions can adversely affect the performance of the cooling machine. If the system is not designed for the rated operating point, the relevant operating data should be obtained from the manufacturer. So, for example, a reverse cycle dry cooler can also be used in hot climates if the solar thermal system adapts accordingly.

Using efficient EC motors in the SAC configuration helps reduce energy consumption. To further reduce electricity consumption, these must be controlled according to operating conditions and cooling demand. Depending on the respective local conditions, the waste heat can also be removed in other ways, for example via wells, pools or groundwater. Ideally, the heat can be used elsewhere.

The advantages of solar air conditioning

Compared to conventional electrically driven compression cooling technology, solar cooling has a no. of advantages. These systems are most useful when the sun shines brightest, in summers. The machines generally use environmentally friendly refrigerants, which reduces greenhouse gas emissions. In most cases, water is used which, compared to refrigerants used in compression cooling machines, has no greenhouse potential. Significant energy savings can result from the fact that these systems simply require auxiliary power for pump operation, heat rejection, etc. if the systems are designed correctly. In addition to cooling, the solar collector system can also provide thermal energy for domestic hot water preparation and heating support, leading to a further reduction in emissions. SACs are also ideal for hotels, supermarkets, schools, factories and large offices, etc. In addition, noise emissions are significantly lower as the machines operate without compressors.

Therefore, solar-based AC systems can offer a reasonable alternative to conventional ACs. In addition to drastically reducing or even eliminating the current air conditioning bill, in many regions, one can receive a large cash back as well as a tax credit for powering their air conditioning with solar air conditioning systems. As of now, capital investments are high, but the system can justify its long-term value. It is only a matter of time before this technology is mass produced, reducing costs to levels affordable for the common man. And then the days that pose the maximum cooling requirements will be the same days that the maximum energy could be extracted from the sun while pocketing all the resulting benefits. The choice would really be ours!
