Understanding the Way Smartphones Work

Mobile phones are one of the most convenient and handy personal technologies that have been developed since the modern era. They offer users a wealth of features that allow them to keep in touch with family, business associates, and others who may live in different locations. A mobile phone can make and receive phone calls over a wireless radio frequency signal while the individual is traveling inside of a telephone service zone, generally, outside the range of a landline. While mobile phones use a hands-free mechanism to convey messages, the term “hand phone” refers to a model that comes equipped with a speaker so that it may be used to accept or reject calls without the assistance of the user. You can see some great models at a Vodafone near me via King Communications.

As the name would imply, mobile phones are useful for making and receiving calls as well as sending and receiving text messages; some models come with built-in cameras and other visual communication devices. The term “web browsing” refers to the ability of some mobile phones to access the Internet on their unit via a wireless network. Many people may assume that mobile phones can only be used for making and receiving calls; however, they can also act as computer terminals by way of applications designed for web browsing. Web browsers vary greatly in both complexity and in feature set from simple software applications to complicated programs capable of providing access to the world wide web.

In the early years of mobile phones, the concept of using a phone for more than one function was still a relatively new idea. Most mobile phones manufactured at that time were not capable of receiving calls and text messages; however, with the advent of advanced technology, newer telephone devices have been released that can perform multiple functions. For instance, some smartphones are equipped with cameras and can be used to take photographs and record videos. Web browsing on these devices has become a popular pastime, and more people are learning how to browse the Internet using their smartphones instead of using a personal computer. With increased functionality coming in upcoming smartphone devices, mobile communication will likely continue to expand into new sectors in the future.

What are the Different Types of Cyber-Attacks?

Cyber attacks can be classified into many different categories. Each of these is used by hackers for different purposes. Some of these attacks are very malicious and may cause serious damage to the computers that are infected. Other attacks are completely unintentional and only cause annoyance.

Image credit

The most common type of cyber attack is a virus or worm. This is done by someone with malicious intent, such as a criminal gang. They use a program or tool to hack into a computer, gain access to sensitive information and then distribute the information throughout the internet. While some viruses do not have these malicious characteristics, they are still able to spread from one computer to another by using file sharing technology. This type of attack can also come from an infected email. To help protect your business from the threats that online operations can face, consider Cyber Liability Insurance from a site like JMP Cyber Insurance

Another popular type of attack is a data stealer. This person hacks into a computer and then tries to obtain personal information by using various methods including password theft. Stolen personal data includes financial documents, credit card information, and other types of vital information that could be very useful to someone. If you become a victim of one of these attacks, you need to take special precautionary measures to make sure that your information is protected.

How is Rubber Made?

Rubber is primarily a natural material that is harvested from trees, though it can also be manufactured artificially through chemical means. Latex, like rubber, is typically used as a synonym for rubber, though the word really refers to a particular suspension of tiny polymers that are held together by a liquid medium. These are usually produced in Rubber Mouldings like those from Meadex, as opposed to being carved out in wood.

Natural rubber trees are not only harvested from rainforests in Indonesia, but they can be found in other tropical regions as well. After the rubber is extracted from the trees, it is extracted from the bark as well. The manufacturing method of making rubber involves the process of heating the raw materials, such as rubber, and heating them up until they become soft enough to be shaped into thin sheets. Once the sheets are ready, they are passed through a variety of furnaces until they have been transformed into a thick, vulcanising powder. The practical solutions provided by rubber is immense and has been planet changing.

Image credit

We see natural rubber on products ranging from linings and mattress stuffing to road sealants and air ducts. It is commonly used in the automotive parts industry as well as in the petroleum and petrochemical industries. Synthetic rubber is cheaper to produce and is more durable than natural rubber. Many people consider rubber to be the most inexpensive and versatile synthetic material available to consumers.

Four non-destructing testing techniques

Quality control is a challenge in all industries, but none more so than in metal fabrication. How do you evaluate whether a metal product is of good quality without damaging or destroying it in the process? There are a number of possible solutions to the problem, with the following four techniques the most common.

Image Credit

Magnetic particle inspection (MPI)

MPI only works on metals that are susceptible to magnetism, such as iron, steel, nickel, cobalt, neodymium and certain alloys. The item is exposed to a strong field or an electric current until it is lightly magnetised, at which point iron filings or a similar material suspended in a liquid are brushed onto the surface. Cracks, fissures or irregularities left by imperfect surface treatments tend to exhibit greater magnetic activity than intact areas, so these become highlighted by the liquid iron solution. The drawback of this method is that it requires specialist equipment and training to properly apply the liquid and interpret the results.

Radiography

As in medical radiography, you can use X-rays to generate a photograph-like shadow of the item’s internal structure, highlighting irregularities in its density. Unfortunately, this method often struggles on objects that have intentionally irregular surfaces and it takes experience to interpret the results.

Ultrasound

Once again, the principle is similar to that used in medicine, with the soundwaves tuned in frequency and intensity to match the substrate. An ultrasonic testing device generates sound in pulses and can detect changes in thickness and density caused either by defects or corrosive deposits, such as inside pipes or drums. Metal products readily lend themselves to ultrasound techniques, as do concrete and some composites, but the drawback is the expertise required to generate and interpret the appropriate signals. Surface irregularities are also challenging for this method.

Liquid penetrants

This is one of the more traditional methods. In its modern form, two liquids are applied. The first is designed to penetrate and quickly find its way into fissures and cracks, while the second is a developer that makes the variations in penetration easy to see. Penetrant testing requires no complicated machinery to apply and relatively little training to interpret, so it is often the cheapest method. The drawback is that the defect must be accessible from the surface.

Surface treatments

Flawless surfaces are not always the objective. The aim of many post-production operations, especially on metal items, is to produce surfaces that will accept useful subsequent treatments, such as colourants or PTFE coatings from specialists such as https://www.poeton.co.uk/standard-treatments/. Non-destructing methods are often vital to check that anodising or another procedure has completed successfully before proceeding to subsequent stages or to assembly. Competent testing reduces wastage and helps minimise per item overheads.

Materials, treatments and testing should all be aspects of a single holistic production strategy; however, choosing the right combination of methods, setting the right parameters and interpreting the test results to make sure all is going to plan is a complex process. Manufacturers should ideally consult testing specialists during their product design.

What are the Qualities of Copper?

Copper has been used throughout history for various things and one of these things is to make the pipes and pots that people used in their everyday lives. Throughout the years, copper has been discovered to have many amazing qualities and one of these qualities is how it conducts heat and this is why people use copper pots and pans in their kitchen and other areas of their home. What are the qualities of copper though, and what makes it so special?

Image credit

One of the most amazing properties of this material is that it is very malleable, which is why it is such a great material to use when making pots and pans. It is because of this malleability that copper is able to conduct heat very well and it is this quality that allows it to be used in any area of the home or anywhere else in the world. Another thing that copper has is the ability to be ductile material. This means that it is strong enough to be bent into the shapes and sizes that people require without breaking or denting the material and without causing any damage. For Copper Pipe ranges, visit a site like Watkins and Powis, suppliers of Copper Pipe products.

Some other properties of copper that are important to note is that it is known to be resistant to corrosion so it is safe to assume that it will be able to last for a very long time. You do not want to compromise on anything when it comes to your home and you certainly do not want to do that with something as important as your plumbing system, so you should make sure that you are taking every step to protect it at all times.

What does the plasma spraying process involve?

In the industrial manufacturing business, there are many different types of spraying processes that are used by several companies. The most common one that you’ll find a lot of industrial businesses use is the plasma spraying process. Why? Due to its versatility, the plasma spraying process can be used on several coating materials because of the particularly high temperature used.

Image Credit

Yet, do we fully understand what the plasma spraying process involves? Let’s take a look.

Plasma spray

This is a thermal spray covering process used to create a high-quality coating with an amalgamation of four things: a high energy heat source, a slow spraying channel, high particle speeds, and, of course, a high temperature.

Plasma is the term used to describe gas, which has been elevated to such a high temperature, and it ionizes and effectively becomes electrically conductive. The use of plasma spraying technology permits the spraying of almost any metallic or ceramic onto a wide range of materials with remarkable bond strength, while diminishing bending of the substrate.

However, the process can be achieved by using a mixture of different methods. Along with plasma spraying, these involve, HVOF (High Velocity Oxy-fuel Spraying), electric arc spraying, and wire spray. A full description of each method can be researched via the Thermal Spraying and Surface Engineering Association, and more about arc spraying can be found via Open University Science Technology Department.

Image Credit

Next, we’ll take a look at how materials can benefit from the plasma spraying process.

Benefits

With a great ability to spray an extensive range of materials, plasma spraying is perfect for metals and refractory ceramics. The benefits of this type of spraying include:

• Protection from corrosion
• Resistance from wear and tear
• Clearance control of both abrasives and abradables
• Resistance from heat and oxidation
• Temperature management
• Electrical resistivity and conductivity

Materials and function

As the plasma spraying process is extremely versatile, it’s chosen by many engineers, since it offers the broadest choice of coating materials:

• Alloys of iron, cobalt, and nickel, due to the process being a true welding method
• Higher melting point materials, such as tungsten and chromium carbides, stellite, and alumina (aluminum oxide)
• For protection from high temperature, zirconia is used, which is alleviated Yttrium (III) Oxide, Methylglyoxal of Calcium Oxide.
• For wear resistance, Chrome Oxide ceramic is sprayed onto printing rolls for easier laser engraving.
• A downhole tool is used to achieve erosion and abrasion resistance.

For more information about the process of plasma spraying, you can visit https://www.poeton.co.uk/standard-treatments/plasma-coatings/

So, there you have it. Plasma spraying is extremely versatile on a number of different types of material, making it the preferred option for engineers and technologists around the world. With its capability to reduce abrasiveness, surface fatigue, and also to salvage worn out parts, the process is clearly a reliable choice for many substances and one that provides excellent results every time.

How We Rely on Technology to run our Homes

In this modern age, we live with so much technology that we can control virtually anything in our homes with a smartphone app. Did you know that todays smartphones are more powerful than the computer that first sent man to the moon?

 

We can control lights, heating and even see who is ringing our doorbell with our smartphones. Technology has also helped us to stay in touch with friends and family over the last year, when due to the global pandemic we have not been able to meet up with them physically.

Image Credit

Life has become increasingly easier in the home thanks to the ingenuity of inventors who have created things which have ended up becoming part of our basic home essentials – here are a few things which changed the way we live our lives at home…

 

Central Heating – The first heating is thought to have been invented by the Romans who invented underfloor heating. But modern central heating was created by an American inventor called Birdsill Holly. Today we would struggle without our modern heating systems and when it breaks down we simply call someone like this boiler repair Gloucester based company HPR services to come and put it right for us.

Deep Freeze- Many people experimented with lowering temperatures artificially to preserve food, but the freezer as we know it did not start to become a part of the home until the 1950s, when the technology was made suitable for the home.

How technology is advancing construction

Technology is currently transforming every industry. The construction industry has been slower than some to embrace new ways of working, due to the time involved in projects. However, due to amazing technological advances, the construction world is fast changing and here is how:

3D printing

Already a building in Copenhagen has been made using 3D printing to build structural walls. This has become known as building on demand. This technique has many benefits, including a reduction in costs. With 3D printing, there is also the opportunity to include technology directly into the walls, meaning a complete integration of tech for smart buildings.

Image credit

BIM

This stands for business information modelling and it is beginning to play a large part in construction projects across the world. Keeping costs down is of major importance in any building project and by creating a digital map of a building before construction even begins, helps to identify any issues before a single brick is laid. It is possible to bring the building to life in virtual reality, significantly helping builders and property managers. For Construction Companies Manchester who employ such technology, visit Piggot and Whitfield

Drones

For mapping hazardous sites, drones play an essential role. The data they capture can be used to make more accurate assessments, reducing delays caused by human error and pushing up costs. Drones can make processes faster and make jobs safer. The photographs are high-resolution and the information from them can be used to create 3D models.

How hospitality can learn to live with Covid-19

The Chambers Dictionary defines hospitality as ‘(friendly welcome and) entertainment of guests … a room or a suite where guests, delegates, etc are welcomed and entertained’. We are social creatures; for many of us, hospitality settings are the backdrop to our lives. Generation after generation has gathered to share key life milestones in restaurants, bars, cafes, hotels, and every other kind of hospitality setting. The global pandemic challenged the hospitality sector to its core, so let’s take a look at how hospitality can learn to live with Covid-19

Adapting to a socially-distanced world

Hospitality was crippled when lockdown began in March 2020. Businesses closed with no idea when or if they would re-open. Many entered lockdown after a tough first financial quarter, adding hardship to an already brutal change in circumstance.

Businesses of all shapes and sizes rose to the challenge and adapted with ingenuity and grit, with takeaway and delivery services keeping businesses and communities afloat during a time of deep uncertainty. Experts warn that it is essential for hospitality to create medium- and long-term solutions for living with Covid-19, starting with solid communication.

Communication is key

UK Hospitality, the country’s top trade association, forecast that one million jobs would be at risk and one-third of the hospitality industry could be permanently shut down. Furthermore, the hospitality sector is likely to be the last to emerge from the financial fallout from the pandemic. As a result, hospitality faces a defining communications challenge.

Image Credit

During lockdown, communication strategies focussed on logistics, such as how delivery and takeaway services would operate and keeping customers updated on radically different opening hours. Industry-specific experts, such as food PR agency staff, say that the focus must now shift to operations.

Businesses must address how they will operate and pivot their communications strategy to include their new operating models. Solid communications strategies showcasing new operating models, perhaps with the help of a food PR agency, will reassure staff and customers nervous of social interaction. Industry experts warn that without a clear operations narrative in their communications strategy, businesses will struggle to stay afloat.

Will hospitality survive?

The world is transitioning to a new way of living. Anyone who has worked in hospitality knows that part of the job is smiling through chaos and uncertainty. If any sector can reinvent itself and thrive, it is the hospitality industry.
