How to Reduce the File Size of Videos in Various Ways

Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Reduce the File Size of Videos in Various Ways. Videos are known to have large file sizes that can range into several gigabytes. The longer the video and the higher its quality, the larger its file size tends to be. The fact that videos are so large can pose a lot of problems. Not only will they take up more storage space, but transferring them can present more of a challenge as well. That is why it can be helpful to know how to reduce the file size of your videos, in a number of different ways.

How to Reduce the File Size of Videos in Various Ways

Let's have a look at How to Reduce the File Size of Videos in Various Ways. All these ways are mentioned below in detail:

Transcoding the video codec

Most videos are already compressed in some fashion, but not all video codecs are equal when it comes to the efficiency of their compression. In general newer codecs are able to compress video data more effectively, and so you may want to transcode to one with better compression. The only caveat is that newer codecs aren’t as widely supported, so you will need to check that the device or platform your video is to be played on does support it. At very least you should transcode videos to H.264 as it is almost universally supported. If it is an option you can transcode to H.265 (HEVC) to reduce the file size even more, but it is not nearly as widely supported. The main advantage of this option is that you will be able to reduce the file size of your videos without affecting their quality.

Adjusting the video bitrate

By definition the video bitrate is the amount of data that the video can use each second. That directly affects the file size, which is essentially the video bitrate multiplied by its duration. Lowering the video bitrate will let you reduce the file size of the videos as much as you want. However it will affect the video quality as well, and compression artifacts will appear if you lower the bitrate too much. The optimal bitrate for videos depends on several factors, such as the video codec, resolution, and frame rate.

Extracting short clips from videos

As you can imagine this option won’t reduce the size of the overall video – but it will let you end up with a smaller-sized video. It is only useful in situations where you are interested in small parts from much longer videos. By extracting short clips from your videos and saving them separately, you will end up with videos that have significantly smaller file sizes. The exact difference will depend on the length of the clips you’re extracting compared to the length of the original video. Keep in mind that none of the options listed above are mutually exclusive, and you can use them in combination with one another if necessary. For example you could convert a H.264 video in MKV to MP4 with H.265 (HEVC) using Movavi Video Converter, then reduce the bitrate, and extract the clips that you want from your video. As you can see the exact options you’ll want to use will depend on your specific circumstances. It is ‘best’ to transcode the video without affecting its quality – though that may not always be an option that is available to you. If it isn’t (or if you need to reduce the file size further), reducing the bitrate or extracting short clips are your best bets.

Best Data Recovery Software for Emergency Cases

Hello friends, I hope you all are doing great. In today's tutorial, we will discuss about Best Data Recovery Software for Emergency Cases. Do you know this nasty feeling when you need an important file and it is just not there? Or what about realizing that the huge block of data that you need so badly has been deleted just a couple of hours ago? That’s a feeling you can never forget even though you would like to. Don’t worry though. There are solutions for everything, and the offer is always there where the demand is. There are plenty of special tools used for files recovery. You might object that not all of them are efficient enough, and you are absolutely right. Some tools can recover only a limited volume of data. Others work only if the files disappeared from a PC, but not from connected devices, and so on. So, now you are selecting one of the best data recovery tools. What about checking Disk Drill then? It might be the solution you are looking for.

A Tool That Takes Care of Your Data

If you have deleted a file accidentally, it is an emergency. If the file was stored in an external disc, the situation would be lost with many other tools. However, Disk Drill, the best free data recovery software for Windows, is different. It restores files from everywhere. If you have deleted them from your PC or any other external device, just run the tool. It will recover whatever is still possible to recover. You might be wondering why it is the best professional data recovery software for Windows. Then, just a quick question: what would you do if your files were damaged by a virus? Or if they disappeared due to a computer failure? Do you know any free recovery tool that would handle this unpleasant situation for you? This best data recovery software for PC does it. It recovers files just from everywhere, even if they were lost in any circumstances. The tool works perfectly if the data has been lost recently. But if that happened a while ago, Disk Drill might need more time. Not everybody can sit in front of a lap waiting until the files are back. But that’s why we are talking about the best data recovery software. The process can be paused, stopped, resumed whenever you need it. So, you can start the process, then pause it, and resume it again when you want.

Paid Versions Offer More Opportunities

Now, you might be wondering why one would pay for a Premium Version if such opportunities are available for free. Well, as you can guess, there are some limitations:

• You can recover up to 500 MB for free
• Partition search is available only with paid versions
• Reconstruction of more than 300 file formats

For an individual use, a free version is probably more than enough. But if you run a business or if your work is connected with data, then a paid version would ensure for you the highest safety level of your data.

How to Power a Micro Linear Actuator

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Power a Micro Linear Actuator. Before powering your micro linear actuator, make sure to pick the most quality option that fits your particular goals best. The four most important features your actuator of choice must have are technical features and capabilities like: pushing/retraction power, operating cycle, speed, load factor, and others. Check these and the following features as well in the manual that comes with your actuator.

How to Power a Micro Linear Actuator

• Operating features like temperature limits, sensors necessity etc.
• Price.
• Accessibility.

And don't forget about actuators' optimization. It is very important as well. So, after you've picked and got your micro linear actuator delivered, it is a high-time to power it up. Powering linear electric actuators is pretty much easy and it usually doesn't depend on what exact type of actuator you have. Most DC- and AC-type actuators operate from the power supply and a DPDT (Double Plie, Double Throw) switch. Make sure you get a switching power supply that has a 12V output cable of a 6A. With this, you are able to work and operate all of your struts at the same time. And those struts can be under the full load. Make sure you know how many struts you need to operate at once. If it is only one strut, then you'll be fine with a 3A supply. And you should know how much force is being pushed unto each one of your struts. Because the amount of the current drawn depends on that force. Try to wire them concurrently. It is the easiest way. But there is a possibility that they won’t work synchronously. You need to make sure that they are bolted together. In case if they are misaligned, there is a high possibility that the thing you mount the actuator to will break. Or just make separate switches for each strut. With that, you will be able to control each actuator separately. Here is the part where you can find out how to change the direction of the current via reversing the polarity. The easiest and the only thing to do is to use a DPDT switch or a relay. The scheme for wiring with a DPDT switch looks like this: And the scheme for wiring with a relay looks like this: When you buy switches, check that they are rated at least 3A (works well with one strut) or 6A (works well with two struts). Both of these switches can control the electrical current. If you go and get smaller or cheaper switches just know that they actuate the coils of bigger (10A) relays. And those are the subjects to the reversing and enabling the power. If you are attaching the actuator to your desk that has only one single strut which is in the middle, think about adding some additional stabilizing details at both sides of this table. You can add arms, or scissors, or anything else you might find interesting or handy. And with that, you have a possibility to get rid of alignment issues. And no additional synchronization is required if everything is done right. If you are planning to lift something that weighs more than 150 kg, consider adding another strut. This will enable the support of up to 300 kg on your desk. How cool is that? Btw you can also automate it by interfacing any Microcontroller like Arduino Nano etc.

Conclusion

There is nothing scary or difficult in powering a micro linear actuator. There are some schemes that you might find useful for your case. Remember that everything you do is an art, so building something with a dash of engineering makes it even cooler. Good luck with actuators!

Robotic Tailoring is The Future of Fashion (sewing machine)

Technology has advanced a lot in the last century with robots doing almost everything, from cooking to even sewing. They are able to sew materials, even if it seems like a complicated process, making them now an important part in the fashion, as we know it. Automation came for every industry, and fashion is not going to be left out; it is changing the minds of everyone involved from manufacturers, retailers, to stylists and designers. The robots are already here and various brands are using them in their process of creating trendy clothes, making every aspect of the industry automated or improved by tech. For years, we have been helped by robots that are able to cut through anything, but when it comes to sewing, as it required in fashion, is a process a lot more complicated that takes time to perfect. Tech will evolve in the future and smarter robots are going to take over every industry. In some fields, automation has already surpassed expectations. For example, there are robotic pool cleaners that eliminate the need for workers to tend to clean the pools as the devices already deliver perfection. The latest robots are able to clean all the surfaces of a pool while maintaining a high energy efficiency to help save costs, and who knows what else the future holds. Seeing how profitable it is to replace people with robots, some companies are even launching robots capable of sewing by combining software and hardware in one process. Brands are already using some of the most popular 3D tech or even the latest sewing robots. While some brands plan to bring their production closer to their office, others are using 3D technology to give people customized goods only available by order as well as opening new horizons for easy customization.

CHANGING THE BUSINESS

Electric sewing machines have been around since the WW2, but they could only work with the help of a human being. Nowadays, the automatic revolution has begun reducing the number of workers needed for mass production of clothing to more than a half. Robots are built with sewing and cutting the fabric features. AI is already affecting the big brands into making smarter decisions about their products, turning the next era of fashion into an era that is about their way of predicting and customizing their goods. Large fashion companies are using technology to understand their customer’s needs, a factor that is growing their profits, allowing them to predict what customers will want to wear not so far in the future, as we anticipated before. When the sewbots evolved, they took over many tasks performed by humans leaving them without their jobs and main income. While the fashion industry evolves, the humans must search for other places to work that have not yet been taken over by robots. On the other hand, with robots replacing the sewing machines, the productivity has increased making some companies able to supply their merchandise to their customers quicker. It’s not to say that it has become futile for the fashion industry yet, but the truth of the matter is that everyone seeks efficiency, especially when discussing business. The heavy duty sewing machine is irreplaceable for fashion from many points of view as it withstands intense use and delivers the speed this industry needs, being able to sew at a moment’s notice. It needs to be operated by a person who can work for a limited number of hours per day, however, and who might even make mistakes. This isn’t an issue to be had if the process is conducted through robotic tech as human error and needs are taken out of the equation, which results in higher profits for business owners and increased production. The rise of the robotic tailoring has made popular seasons almost disappear from the industry, another detail worth mentioning, and now more brands are announcing micro-seasons instead of the old seasons. To keep up with the advanced tech brands, the traditional ones began releasing more and more and created their own seasons.

BENEFITS

Besides making the process of creating clothes quicker, the using of robots in the clothes business has other benefits. This robotic industry will help many companies go back to where they started, which will eliminate the need for skilled labor, a short supply there and too costly for most of their customers. It will not produce many factory jobs but would generate more jobs in the administrative and managerial level. Overall, robots in the fashion business may have a positive outcome, but it can have a negative impact as well. It can allow us to take overseas jobs, for example, and cheaper clothes, but the impact on the economy of developing countries could be catastrophic.

THE DOWNSIDE BUSINESS

The dark side of this new environment is caused by the low-cost, low-quality clothes in workshops with uncertain working conditions, with low-paid workers. Moreover, the cheap fabrics used to make inexpensive clothes are treated with bad chemicals. The fast fabrication generates massive textile waste, which damages the workers and the surroundings. According to EPA, around 13 million tons of clothes are disposed of every year. Some of the robots created only work on a specific type of material, a challenge for manufacturers in the beginning, but now they found a way to manipulate the materials, to make them compatible. To this option are of course some limitations, because materials need to be completely wet, and certain fabrics are to be used, but overall, the process is doable. We are almost sure that they will not take over the world and make us their slaves, so do not worry about that. Let us not forget that the making of a robot could take months, only making the water-soluble thermoplastic to stiffen fabric to be like cardboard takes a lot of time. However, when it comes to stitching together complicated patterns, human hands are still the best option rather than those inflexible robot hands.

Role of PCB in Modern Life

Hello friends, I hope you all are fine and will be doing something special in your life. In today's post, we are going to discuss The Role of PCB in Modern Life. A PCB  is a thin board made of fiberglass, composite epoxy or other laminate material. A conductive pathway is etched onto the board connecting different component on the PCB, such as transistors, resistors, and an integrated circuit. PCB is used in both desktop and laptop computers. It serves as a foundation many internal computer components such as video card, network interface card, controller card, an expansion card. These components are connected to the motherboard, which is also a printed circuit board. PCB is used in different industrial projects and electronic devices. PCB can be single sided, double sided or multi-layer. Large no of PCBs can be fabricated at the same time. PCBs can also be made manually in small quantities, with reduced benefits. In today's tutorial, we will discuss its role in our life, working and also discuss electronic devices in which it uses. If you have any question about PCB, its construction and design, please ask in a comment I will try my best to resolve your problems in a comprehensive way. So let's start with the Role of PCB in Modern Life.

Role of PCB in Modern Life

• Before the development of the printed circuit board, the circuit was wired point to point on chassis. The chases were a sheet of metal frame or pan. The circuit on chassis was large, bulky, heavy and relatively fragile. Its production was labor-intensive, that way projects were expensive at that time.

• With the passage of time, as technology improves Austrian engineer Paul Eisler invented the printed circuit as part of radio set while working in the UK around 1936.In 1941 multilayer printed circuit used in German magnetic influence naval mines.  In 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. After World War II PCB was available for normal life use in different products.
• After PCB brief history now we discuss modern PCB.
• A modern PCB consist of a flat sheet of insulating material and a layer of copper foil. Chemical etching divides the copper into separate conducting lines called tracks or pads for connections. The tracks function as wires fixed in place, and are insulated from each other by air.
•  A surface of a PCB may have a coating that protects the copper from corrosion and reduces the chances of solder shorts between traces or undesired electrical contact with stray bare wires.
• Printed circuit board have multiple copper layer. Two-layer board has copper on both sides, multilayer boards sandwich additional copper layers between layers of insulating material.
• Pattern to be etched into each copper layer of a PCB is called the "artwork". PCB design can be mass-reproduced in a way similar to the way photographs can be mass-duplicated from film negatives using a photographic printer.
• When a PCB has no components installed, it is less ambiguously called a printed wiring board (PWB). A PCB populated with electronic components is called a printed circuit assembly (PCA).

Now let's discuss PCB manufacturing and printing.

Manufacturing of PCB

In the next few lines, we will discuss how PCB is manufactured. But if you don't want to get into trouble of PCB manufacturing then you can get them manufactured by awesome some PCB company named PCBWay. It's one of the most trusted PCB services available online. We have had a pretty good interaction since last two years and we always remained satisfied from their servicies. So, I would recommend PCBWay to you for all of your PCB manufacturing.

• Schematic for the Circuit

First of all, the designer creates a schematic. A schematic is like a road map for a circuit, it contains a series of symbols that represent of aspect of the circuit. This is helpful for troubleshooting any issue with your PCB.

• Use of EDA Software

After the Circuit Design is captured in a schematic, it is translated into an electronic design automation (EDA) software package like altium designer. Designed has to supported into industry standard format e.g. the Gerber format,. The resulting file acts as a set of instructions for the production phase of a PCB.

• PCB Printing

After creation of a Gerber file, we make print  PCB. Dimensions of PCB, along with how many layer it will have are decided and all of the components are positioned, ground,  laid out, and signal traces dictated by the Gerber file. There is a different requirement of a different board, so your PCB designer will tell you whether you need surface mount (SMT), single or double-sided fabrication and more.

• Test  of PCB for Functionality

After all, the process describes above we do, White-box testing will make sure your PCB is structured properly. The goal here is to test every possible output to ensure the PCB is functioning, the designer intended it to. For better under as standing of PCB manufacturing and its part, lets have a look at its figure.

Role of PCB in Medical Science

It will be interesting for you that PCB is not only playing a role in Electrical and Electronics industries, but it also plays an important role in Medical Science. Lets discuss its important role in Medical life.

• The range of printed circuit boards applications in the medical field is vast and ever-growing. You can find medical printed circuit board in everything from  pacemakers, defibrillators and heart monitors in the case of cardiovascular medical specification PCBs, to medical imaging systems, CT scans, MRI, ultrasonic equipment and more.
• You will also find PCBs for a medical device like blood glucose monitors, temperature monitor and electrical muscles stimulation equipment.
• Professionals of Medical Industry will often select flex or rigid-flex PCBs for their important medical devices. This is because medical devices often do not conform to typical standards of PCB size, shape and medical device professionals will want to make sure their printed circuit boards can fit into as small of an area as possible while still remaining resistant to damage.

In the given figure, these are some devices which uses PCB.

Applications of PCB

Now a days PCB has become most important in our modern life. It uses in almost each and every electrical and electronics component. These are some applications of PCB.

• PCB based Aluminum used in different electronics devices such as computer and in cars indicators.
• It also used in consumer instruments such as mobile, smartphones and computers.
• PCB also used in medical industry equipment such as ultrasonic, machine, MRI etc.
•  In industry, it has its applications in Dashboards, Engine Management Systems (EMS), power supplies, in car entertainment, fuel regulators, heater controls, and satellite navigation.

So this all about Role of PCB in modern Life. I hope you liked this tutorial. If you have any question please ask in a comment, I will resolve your query. Thanks for reading. Take care....

What We Can Produce from Color-Coated Rolled Steel

The technology of manufacturing color-coated (or pre-painted) steel was patented by the UK-based company British Steel in the late 60s. Since then, galvanized steel with color coating has been used in the construction industry as a material with an optimal cost/durability ratio. In addition to the decorative function, color coating provides additional protection for galvanized steel from the influence of adverse environmental factors.

What is color coating?

Color coating is a film that consists of zinc, aluminum, or various alloys with a thickness range of 30-250 micrometers. This film protects steel materials from damage and corrosion, greatly improving their properties. The maximum adhesion of high-molecular compounds to the surface of a steel roll is provided by the layer of primer which is preliminarily applied to the material. A color-coated steel roll can have several layers of coating. The process of coating is rather time-consuming. That is why some manufacturers prefer a self-adhesive polymer film which is sometimes used to temporarily protect steel products.

The advantages of color-coated steel

The main advantages of steel with color coating include:

• Increased durability;
• Perfect adhesion of the coating to the galvanized base;
• High level of customization. Color-coated steel can be painted or given a matt or shiny look depending on its application;
• The resistance of color coating to UV irradiation;
• Maximum effectiveness of corrosion protection;
• The thickness of a steel roll can be increased without a perceptible change in weight, which is important for construction purposes;
• The possibility to give the material a graphic texture when using it for decoration;
• This material offers a high level of protection from mechanical damage, chips, and delaminations resulting from impacts and excess loads.

What we can produce from color-coated rolled steel

Convenience and outstanding durability regardless of conditions are two of the main reasons why color-coated steel is used so widely in a variety of spheres, including manufacturing, automotive industries, and construction. Below are the basic applications of color-coated steel products.

Construction and infrastructure

Easy to install and dismantle, color coated steel is widely used for the manufacture of domestic or industrial roofing and cladding, exterior and interior decoration of buildings (for instance, Venetian blinds and false ceiling), as well as the construction of frames for drywall and other finishing materials for repair and construction works in the premises of any purpose, including apartments and country houses. In addition, color-coated products serve as reliable building materials for:

• Warehouses and cold storages;
• Atriums in malls;
• Showrooms and airports.

White goods

Due to their durability, high quality, and a wide range of colors, pre-painted steel products offer a variety of design options and ensures maximum efficiency of white goods, including:

LNG Transfer Systems – The Complete Guide

Hello everyone, I hope you all are doing great. In today's tutorial, I am going to give you a detailed overview of LNG Transfer Systems. In the recent past, there has been tremendous growth in the demand for LNG. This has raised the LNG shipping rates around the world. The growth in demand is expected to keep increasing and reach a factor of 50 per cent by the year 2020. It is also estimated that the global cryogenic market will hit an all-time high of $21 billion by the year 2021. Most shipping companies are going for LNG as compared to conventional fuels based on oil for their ships. The lowered limit on air emissions, need for efficiency and increasing operational costs has pushed many shipping firms to look for better fuel for their maritime activities. LNG has proven to handle these challenges better. This is why you now find that vessels, including tugboats, cruise liners and tankers, have adopted LNG fuel. Safety is one of the most important aspects that come into play when transferring LNG to the vessels. There has been a spirited effort to look for technologies that will cut down the risk of accident spills significantly. Luckily, there have been several steps towards the goal with decreased spills both at the harbour and high seas. Here is a look at some of the most common LNG transfer systems.

Ship to Ship Transfer (STS)

This method denotes the transfer of LNG or LNG bunkering from the carrier ship to another. The process usually involves two ocean-going vessels or at the harbour where the moored ship is usually docked or moored at a pier. The process can be done with several types of vessels that include FSRU, LNG Carrier, LNG bunker barge and LNG feeder ship. The operation can either be done as a cargo transfer or fuel a ship propelled by LNG.

Hose Transfer Systems

The use of hoses and hose reels for transferring LNG fuels is one of the commonest transfer systems, especially at the harbour. This process generally involves the connection of hoses from the source of the fuel to the tanker being fuelled. There is also an emergency release system that shuts down when a leak is detected on the hoses; the source or the tanker to which the fuel is being transferred. This method has been gaining popularity in the recent past due its cost-effectiveness and safety compared to the traditional loading arm technique. New technologies have made leak detection, as well as shut off automated, thereby lowering the risk of a spill with over 80 per cent.

Loading Arm System

This is the oldest method used for fuelling tankers and other vessels at the harbour. It is still capable of being used for LNG transfers. However, the method is less desirable for modern transfers due to a number of problems. There have been many instances where the arms have been found to be severely damaged. LNG is also transferred in very low temperatures. Temperatures in the range of -163 degree Celsius are likely to cause ice build up and create thermal shocks to all the systems involved in the transfer of the fuel. These two major problems have led many players in the industry to warn shipping companies of the increased risk of catastrophic disasters from the thousands of tons of fuel. Given that the method is still very popular, there have been efforts to make the process safer. One of the major improvements is the adoption of all-metal arms. These arms come with swivel joints that can move should the ship being fuelled move about on the harbour. The all-metal arms have a lower chance of bursting, and the joints prevent any unnecessary tension or breakage in the process. However, even with these improvements, the system can best be used in the mildest harbour environments, which makes it less convenient. Many shipping companies are going for the flexible cryogenic hoses. Their flexibility and ability to perform well in harsh environments have made them one of the safest methods of transferring LNG to the vessels. These hoses are usually fitted with emergency release couplings along the entire transfer length. The couplings come with a double closing valve technology, which cuts supply from the source for a fast and safe shutdown if a leak is detected. The flexibility compensates for sudden movement of the tanker.

Safety During LNG transfers

Maritime organisations around the world have come up with several measures to further enhance safety during LNG transfers. Here are some of the guidelines put forward.  Emergency Response Programmes:

• There should be plans to deals with potential hazards during transfers such as fires starting in the bunkering areas
• Loss of power during the process
• Unexpected movement of both the vessel and or the bunkering unit
• Leakage

An emergency plan includes fire fighting equipment, first aid equipment, and emergency power backup, among others. The plan should enhance control, mitigation and elimination of risks.

Division of Tasks

The LNG bunkering facility, receiving ship operator and the master of the receiving ship have responsibilities to ensure that all the procedures have been followed. Each of the stakeholders is responsible for the teams working under them. Therefore, each should take all possible care to prevent any damage to facilities and injury to crew members. In addition to the above, there should be a checklist of all the conditions that should be met to ensure enhanced safety. There is also LNG bunkering safety training that should be taken by all crew members involved in the fuelling process. LNG is rapidly gaining prominence among maritime organisations around the world. With more ships on the line for fuelling, safety should always be at the forefront before, during and after LNG transfers. The skills of the crews working in the process should be enhanced, and procedures followed to the letter. In addition, the use of technology is vital in dealing with any risks and challenges in the process. With several smart technologies in the market today, there is even a better chance to enhance safety and efficiency in LNG transfers than it was possible a few years back.

How Technologies Are Changing Education in the 21st Century

Hello friends, I hope you all are doing great. In today's tutorial, we are going to have a look at How Technologies Are Changing Education in the 21st Century. Technological advancement has had an impact on almost all areas of our life in recent years.
