Filing equipment used in offices and other places come in different forms. Traditionally, the term filing equipment was used to refer to office furniture as important data was stored mostly in drawers and cabinets. However, file storage systems in the office and at home went through a series of changes when computer storage was introduced. Not too long after the thriving of this type of storage system was cloud storage introduced. Currently, the latest data storage trend is NAS.

A Raspberry Pi NAS is a network that is connected to a computer. The role of NAS is to provide a file-based storage system that different devices can access through a network. A Raspberry Pi NAS Unit is, therefore, a type of server that does not have a keyboard or a display. However, the unit is controlled over a network on which it is configured using a browser. In this post, we look at DAS and NAS, their differences and similarities.

The Difference Between NAS and DAS

NAS is a Network-attached Storage while DAS is a Direct-attached Storage. Below are a few of the major differences between these two storage systems;

• The main difference between DAS and NAS is the fact that DAS is normally an extension of a server that is already in existence. This means that it does not require a network of its own. On the other hand, NAS is a sort of server through which files are saved and shared over a network.

• In terms of performance, NAS beats DAS because it can be precisely tuned for file serving. This is a feature that is not available in DAS.

• Another difference is that DAS unit is limited to a specific host. However, using NAS, it can be used by other hosts. Some techies explain that DAS is the building block of NAS.

• DAS is also connected to a server or a particular work station directly. On the other hand, NAS requires an intermediary. The intermediary is normally either a network or a USB cable with which the unit can be connected to a computer.

• One of the main cons of DAS is the fact that it does not provide efficiency for sharing data with other servers. On the other hand, NAS allows low volume access to incredible amounts of storage by more than one user.

• The performance of NAS is greatly dependent on the speed and congestion of the network. On the other hand, the performance of DAS is dependent on the speed and congestion of its connected server.

• Finally, DAS is more customizable than NAS in terms of its hardware and software because it is a general-purpose server.

Similarities between DAS and NAS

Below are some similarities between these two storage systems;

• Both NAS and DAS are used to increase the availability and accessibility of data. They also both work by using either RAID or clustering technology.
• Another similarity is the fact that they both can have different amounts of cache memory. The amount of memory on each affects its performance.

Conclusion

Choosing the best data storage mechanism can be hectic. However, you can lessen the workload by simply looking at the pros and cons of each mechanism.

A truck head is an engine that pulls the rest of the truck. Be it in SUVs or trailers. It is something that must be taken into consideration lest you risk having a truck that cannot perform the intended tasks efficiently. But before we go into the essential aspects of a truck head and look at the importance of a truck head, we should be in a position to know what it is.

A truck head is sometimes called a towing head, and it is specifically designed to tow a trailer. In some places, you will get people referring to it as a prime mover. In Japan, one of the leading manufacturing countries called a trailer head.

The different types of truck heads

Truck heads come in a range of designs that are meant to meet specific needs. However, the two broad types are the semi-truck head and the full truck head.

• Semi-truck head

As the name suggests, these types cannot support the entire trailer on auxiliary wheels. They are usually fitted on their rear wheels of the trailer to be fully supported.

• Full truck head

A full truck head can move along even without the support of the rest of the trailer. They have both the front wheels and the rear wheel that make movement possible. They are very common designs and are ones that are mostly used to tow hefty cargo trailers.  Some models lack the engine to self-propel while others have.

The functionality of the truck head

Mot tractors and trailers are built to carry heavy loads ad tons f cargo over long distances. So the essential thing to look for in a truck head is always the loading capacity. The coupler and kingpin of a truck head are the parts that shoulder the weight of the trailer once it is connected. The containers are not fixed with engines, so they are loaded on truck heads to be propelled.

The part that connects the trailer to the truck head is called a fifth wheel, which is the part that plays the role of cargo connection. This par brings forth the force that can pull up to 10 tons of cargo. When buying a truck head, it is essential to look out for this part. It always bears the maximum towing weight of the truck head.

Single vs. double-truck head

These are some of the terms used to describe truck heads. Here are their meanings.

1. Single truck head: this is a truck head with only one differential gear. They come with six wheels and two axels.
2. Double truck head: these ones have three axels, ten wheels, and two differential gears.

The terms single or double are only used to indicate the number of differential gears in the truck head.

Final words

The world of logistics and transportation at large is very much dependant on trucks. It is essential to have the necessary knowledge of trucks because you might find yourself in a situation where you need one even if you are not in it to buy.

Projector design, like all other aspects of technology, is adopting miniaturization. Components are getting smaller with the development of more advanced chipsets. The next frontier in projector technology is mini movie projectors. The hugely reduced size and minimal weight of the mini projectors make them super portable. Additionlly, the main discoveries in light projection techniques and technologies include:

1. Laser Beam Steering (laser) projection
2. Digital Light Processing (DLP)
3. Liquid Crystal on Silicon (LCoS)

Mini projectors integrate many technologies to end up with a final working device. The core technologies utilized in mini projection also rely on connection technologies such as HDMI, USB, and SD cards. Specialized software is integrated into mini projectors to control all the components and keep them working in harmony. Let us now review each of these types of mini-movie projectors and their technologies.

• Laser Beam Steering mini movie projectors

The company that initially developed the concept of laser beam steering for mini projection capability is Microvision. The company successfully implemented scanning mirror technology, also known as the Micro-Electrical-Mechanical-System. This consists of a minuscule silicon component that oscillates a tiny mirror vertically and horizontally in the direction of a colored laser beam. The software redirects this beam to build the image pixel by pixel. The commercial version of this technology is called PicoP.

• Digital Light Processing (DLP) mini projectors

Invented and publicized by the hugely successful Texas Instruments company. Previous larger designs made use of spinning color wheels and lamp combos to run the mini projectors. The newer DLP concepts replaced the combined lighting system. The smaller models are made possible by extremely bright LEDs, which also make manufacturing very cheap. DLP works to create an image by directing the LEDs through tiny mirrors arranged in a matrix format on a semi-conductor called a Digital Micromirror Device (DMD). The result is smooth, stable images without the need for a bulb. This makes DLP the most popular technique for mini-movie projector design.

• Liquid Crystal on Silicon

LCoS is somewhat similar to DLP, with the only difference being in the way the mirror arrangement of LCoS utilizes Liquid Crystals. Mini movie projectors created using LCoS offer higher resolution, high-contrast images, and stable viewing. One benefit of this technology is its maturity, having been first developed by General Electric in the 70s.

Capabilities of mini-movie projectors

As time goes by, many gadgets are shrinking in size, and many can now fit in your pocket. Mini projectors are no different. The existing versions are well suited for multimedia presentations and low-quality videos. The benefits of mini projectors include small size and easy setup and integration. They also come with built-in sound and storage. The disadvantages of mini projectors include insufficient brightness, lowered resolution, and limited sets of features.

Conclusion

Mini projectors have introduced the significant screen experience to our homes. We are no longer in the days when the only place you could watch a movie was a theatre to watch a new movie. Mini movie projectors are brighter, lighter, and easier to install. Modern projectors are smaller, but thanks to visual and digital innovations, the quality of the images are comparable to that of movie theatres.

These shots referred to here do not have to do with firearms or drinks. Instead, we are referring to “polishing” shots or more professionally known as shot blasts. This process of shot blasting involves the blasting of shots (abrasives) at given targets (steel and other metal products). That simply means that shot blasting refers to a system or equipment made in such a way that abrasives (which vary with their material component) are continually fired at the surface of steel or metal products. These abrasives are fired at high velocity. This is not done to damage the material. Instead, if done properly, the use of shots should be able to increase the lifespan of metal products considerably.

How the Shots Matter

These shots are fired to remove particles from the surface of steel and metal products. This process leads to the removal of a layer of the surface. This leads to a matte texture or color. This, however, is advantageous as it causes closer adhesiveness between any coating used at a later time and shinning procedure eventually carried out on the metal product or construct.

This use of shots also tends to make the surface more compact. This would increase the toughness of the surface, it would also reduce the risk of damage to the surface (scratches) brought about by negligible impact. That simply means that the material would be more difficult to damage or deface by scratching.

Types of Shot

These shots or abrasives come in various forms. There are different materials from which these abrasive materials or shots can be made. A few of the more common shots or abrasive materials include:

1. Glass beads
2. Sodium bicarbonate and other synthetic materials.
3. Steel grits
4. Aluminum pellets
5. Silica sand
6. Copper shots and many more

The only major drawbacks of using shots are that, first, the noise generated during the process can be unbearable to many and require operators to protect their auditory senses (using earbuds).

Second, the materials being dislodged from the surface could contain toxic materials that could be hazardous to workers such as Lead (Pb) and even silica sand. Silica sand, in particular, can lead to breathing complications, silicosis, and even lung cancer.  But with proper preparation with earplugs, nose masks, and face masks, these dangers are reduced if not done away with.

After the purchase of the shot blasting machines, a training program for the expectant operators of the machine will be carried out. This is done to reduce risks and avoidable accidents from occurring.

Conclusion

So we can see that shots are extremely important in steel polishing during the steel manufacturing process. The most important reason for this is that the life span of the steel or any metal product is increased and impurities on the surface are expelled. This results in a tougher surface. Another major reason is that it makes the coating and coloring process easier. So a shot whether it is in a wheel blast machine, a sandblaster or even a bead blaster is extremely important in the metal manufacturing industry.

Let get this straight. Used or rejected tires are a threat to the environment and human health. So, what do you do with your used tires? If you are a non-business person, you possibly throw them out.

What if we tell you that you can use your old tires into a new form? Yes, it is possible through tire recycling. It’s a standard way of organizing scrap tires for recycling. But for that, you need the help of technology.

Over the years, tire wire drawing machine is doing the same by turning the tires into small bits.  When it gets new shapes, you can use the resultant as a fuel source, building the playground, making shoes, etc.

Anyway, today we’ll give you a detailed introduction on the tire wire drawing machine and its uses. Let’s get started!

Tire Wire Drawing Machine

Tire wore a drawing machine is a large tire disposal machine. It can pull out the big steel wire from the sidewalls of the tire at one time. It is designed for the tire pyrolysis and shredding tires.

The method to pull out the wire minimizes any damage to the tire shredder’s blade. It results in maximum oil production and high-quality pyrolysis oil as well.

The machine completely pulls out the wire from the tire and exposed to high temperatures. Indeed it’s a handy tool for tire recycling. 

Types of Tire Wire Drawing Machine and Their Functions

Ture wire drawing machine comes in two types including, single-hook and double hook. Both of them differ in their infrastructure and internal mechanics.

· Single-hook Tire Wire Drawing Machine

This type of tire wire drawing machine comes with a single hook. The hydraulic system powers the machine. It features a tire lifting device that raises tire. Then, steel wires from both sides of the tire are hooked through the hook in the cross hole.

It pulls the wire and fixes it on the hook. The hook moves backward with full force to completely pull out the tire. That’s how a single-hook tire wire drawing machine drags out the wire and crush the tire.

· Double Hook Tire Wire Drawing Machine

This tire drawing machine features two dish hook, and a mechanical transmission power system powers the tool. Here the tire has to place in between the double hook. The motor inside rotates the two disk hooks.

Both hooks will take out the steel wires on both sides of the tire. Then, it rotates inward to pull out the steel wire from both sides of the tire.

The Uses of Tire Wire Drawing Machine

Hitherto you know that the use of tire wire drawing machine is to pull-out the steel-wires from tires sidewalls. It completely extracts the wire before cutting and shredding the tire. The tire wire drawing machine makes the shredding process trouble-free. Above all, it hugely contributes to tire recycling procedures.

To End With!

A tire wire shredding machine is a must-have to give your rejected tires a better destination. It also makes tire recycling much more accessible. Thus, tire wire shredding machines will definitely contribute to our economy.

A few months ago, a Colorado dad and son built a replica of a prestigious Lamborghini, thereby becoming prominent on social media. Soon after, they began to share various updates based on their successful project. Of course, these posts went viral on multiple social media sites. The steel-frame vehicle has a composite body with inspiration from the prestigious Lamborghini Aventador.

However, it is not the replica. The two drew inspiration from the possibilities of that project, inspiring kids by teaching them the basics of STEM. It is their hope that the car hits the road soon. So that said, many have asked- is it really possible to build such luxurious cars via 3D printing? That is our topic of discussion in this article by 3d printed Lamborghini.

We currently live in a revolutionary world where everything can quickly transition in a blink of an eye. Electric cars, as well as the self-driven ones, have become a primary part of our daily lives. Organizations are also relying on cloud-to-car systems of mapping to appease consumers. Others rely on driver behavior monitoring systems, elements valued not just by drivers but insurance firms. For that reason, the flexible economic environment coupled with demanding consumers are pushing professional automakers to look for viable new opportunities as well as materials that can help them to catch up with a variety of automaker sectors on the market.

Lately, experts have been disseminating important information regarding how the additive manufacturing technologies, also known as the 3D printing world is changing the production sector, including how vehicles are designed, developed, and then manufactured. And of course, if the commodities are readily available for consumption, they shall also be dispensed into the market.

Over the past few years, the 3D printing world has been evolving. More car manufacturers have come forward with viable ideas on how to manufacture cars using these powerful tools. The initial technology used in car manufacturing was laser sintering. Based on additive manufacturing, this system has been developed to help car manufacturers with the foundation for low-cost prototyping as well as individualized serial production when it comes to high-end car parts.

Being one of the powerful machines in the industry, it is ideal for the manufacture of small-sized cars. The additive manufacturing system also offers an easy-to-access handling station. This makes it easy for the manufacturers to spearhead the set-up tasks ahead.

With the multiple possibilities of producing cars via 3D printing, it is evident that the 3D printing world is set to revolutionize in the next decade. Through rapid prototyping, automobile manufacturers are better-positioned to increase their research capabilities coupled with development processes that would enable them to introduce their cars on the market.

Still, in the automotive sector, there is a specific market movement towards cars with strong structures and high stiffness. These features have a way of enhancing fuel economy. For that reason, the car manufacturers are inclined to using the Concept laser to offer a solution to the impending problems.

Take-Home

3D printing is modern enough to add the performance factors needed to meet various production demands as well as regulations. It is projected that the automotive industry will register a rise in the consumption of different 3D printing materials.

You probably have seen one online and wondered how the 3D printer operates. Well, it is not rocket science and indeed not magic, but a 3D printer could change the way we approach design and manufacturing.

Just in case you are wondering how it truly functions, here are some of the basics of the 3D printer you should know.

What is a 3D printer?

A 3D printer is a tool that is used in three-dimensional manufacturing of a wide variety of objects. And this is done with the use of computer-aided designs. Many of the available brands come in different types, shapes, and sizes, but they perform one primary function, to replicate an actual image from a computer design. For this to be made possible, you would need to provide a base material for the machine to print.

It is like in the case of the paper printer, where you need to provide ink and paper for the machine to use in printing. We can refer to these printers as an additive manufacturing machine since it adds the materials in bits, depending on what you intend to create.

What are the Different Types of 3D Printers?

Just like with regular printers, 3D printers come in different types. The type of machine usually depends on the 3D printer file format or printing process it adopts. Some brands work well with large scale manufacturing, while others make it possible to include multiple colors and materials during the printing process.

The popular types of machine are

• Fused Deposition Modelling (FDM)
• Stereolithography (SLA)
• Selective Laser Sintering (SLS)
• Laminated Object Manufacturing (LOM)

While there are many others available, the four machines listed above are the most common types of 3D printers. The FDM is the easiest to grab for beginners, compared to the rest of them. The material used is usually an ABS or PLA plastic. The printer head melts down the content, and it is then released into the printer bed. These machines are inexpensive and can be quickly built from scratch with the right tools.

The Stereolithographic method is one of the oldest 3D printing methods. It involves the use of a laser to harden a liquid resin with the use of ultraviolet light. While these printers are fast and precise, the raw material, which is the adhesive is usually expensive. SLS and SLA are quite similar in operation, and the only difference is the base material. While SLA makes use of resin, you would need to make use of powdered material with Selective Laser Sintering.

In the case of LOM, the base material is paper or plastic, which makes it cost-effective compared to SLA and SLS. But you should know that 3D designs made from paper wear easily compared to the other methods.

Now that you know what a 3D printer is and the different types available, you should be able to say a few things about these incredible masterpiece printers.

 

 

The molecular weight also known as the molecular mass is the sum of the weight of the atoms to be measured i.e. the total weight of each the atomic masses of the atoms being considered. The unit is given as AMU or u. Or gram per mole (g/mol)

In calculating molecular weight manually, it is important to know the following;

First, that the mole as used in chemistry is the standard method to communicate the amount of substance present in the molecule and is different from the molecule. It is a unit of all that is present in a sub substance a mole of anything has 6.022 x 1023 molecules. Next is the relative atomic masses of the element that are to be measured. While the molecule is the particle that represents the molecular compound and the diatomic element.

Calculating for molecular weight manually takes 4 easy steps;

1. Write out the elements and the number of the present in the chemical substance.
2.  Determine the atomic weight of each of the elements present in the substance (with the aid of the periodic table)
3. Multiply the number of atoms present with their respective atomic weight
4. After multiplying, sum up the values, the result becomes the molecular weight for that chemical substance for example when calculating the molecular mass of water, whose chemical formula is H2O.

There are three molecules present in it consisting of two hydrogen atoms and one oxygen atom. Consulting the periodic table the masses are one (1) for hydrogen and sixteen (16) for oxygen. Calculating you have 2(1) + 1 (16) = 18. So, therefore, the molecular mass of water (H2o) can be given as 18g/mol. As observed, the subscript number attached to the atom is multiplied by the atomic masses of the given atom.

Another important information to note there is a distinction between molar mass and the other concept which is the molecular weight. Both should not be confused for one another for they have different significance, the molar weight of a substance is the mass (usually depicted with a mole in mind) in that substance where the mole can be the number of ions, atoms, molecules, and electrons in an element. Whereas the other has to do with the mass which belongs to a single molecule in that substance mixing these two up can cause parameter error

Using the molecular weight calculator online, you just need to be able to write out the equation of the molecule and input it in the space provided, there, the value pops up immediately. If you type H2O into the bar it gives you 18.0152 g/mol. The extra decimal comes up because of the high accuracy of the calculator.

Molecular weight calculator online is easy to use since there is already a database of the periodic table that is used whenever it is needed, so therefore it leads to lesser error when calculating for your molecular mass. What is only needed is to be able to write out the chemical equation and identify the multipliers.  When using a molecular calculator, the formulas can only have 2 brackets and the crystallization molecule should be placed last.

The molecular weight calculator can either be accessed online or installed on your desktop.
