The history of gadgets spans as far back as humanity itself – since hominids began creating tools to make their lives easier. If you’re looking to become an electrician as part of the construction trades and work on-site to install, repair and maintain electrical systems in new construction and existing buildings, electrical technology is the training you’re after. Agricultural Engineering is the engineering discipline that strives to apply engineering science to agricultural production and farming. In some circles it is commonly accepted that the scope of agricultural engineering is broader than all other forms of engineering, as it combines elements of mechanical, civil, and chemical engineering with animal and plant biology. Nikola Tesla was one of the most important contributors to the birth of commercial electricity. He was originally an employee of Thomas Edison’s and he invented a system that transmitted alternating current, as opposed to Edison’s direct current system. Edison opposed Tesla’s idea, so Tesla set up his own laboratory and announced his invention of the first practical alternating current induction motor and polyphase power transmission system in 1888. The polyphase system would allow transmission of alternating current electricity over long distances. Westinghouse asked Nikola Tesla to join his electric company where Tesla continued his work on the alternating current induction motor and Westinghouse acquired exclusive rights to Tesla’s polyphase system patent. All of our electric motors today run on principles set out by Tesla, such as the motor that produces high frequency signals that are used in radios and TVs. He also set the standard for the frequency of the transmission current, 60 hertz, which we still operate at today. Fastest medium of information dissemination: It is the fastest medium of information dissemination especially if it is bulky. I remember waiting for the news vendor (print media) several hours to catch a glimpse of the latest news several years ago. But now, just go online, and you are current and abreast with latest news even before the newspaper seller. Users shouldn’t have to edit configuration files to set up a shared printer or a wireless network. Macs face fewer viruses compared to the Microsoft Windows operating system. It’s not like macOS is free of malware and we see vulnerabilities found in the OS from time to time. PCs have been more popular, with the number of Windows operating systems connecting to the web far exceeding those of Macintosh or Linux. The result has been an influx of cyber attacks targeted at PC users and the Windows operating system. But now the times are changing, and Mac OS X’s market share is about 10%, and therefore cybercriminals are taking notice and beginning to set their sights on the Apple operating system.
They are more reliable- Altough nowadays you have Internet anywhere, you may not have access to it, ir if because another reason you can access it, you can just take a book from you backpack and start reading it. In the past, chalk or the blackboard was the main instructional material employed in the classroom. As a result of advancement in ICT today we have interactive board for learning that give access to the internet for further findings which could be useful in whatever topic been taught. IEEE standard 315 is another standard for the symbols on electrical diagrams. IEEE 315 is the same document as ANSI standard Y32.2. IEEE standard 200, the same standard as ANSI Y32.16, was the standard for electronic part reference designations. This standard was replaced by ASME Y14.44. 1. A printed circuit, or printed circuit board (PCB), which is a thin plate on which chips and other electronic components are placed on. A PCB is made of conducting components, inductor contacts, resistors and capacitors. You can find PCB’s in computers, which usually have one or two boards, or cards. As more and more people use computers, this is an electronic component that continues to grow in the areas of technology and information. In static electricity, the charge eventually dissipates by flowing to a nearby area or by a visible electrical discharge and its energy is wasted. In the case of triboelectric generators, however, the charge (in the form of electrons) is captured and transported through a circuit. The electrons have energy and can do work. Not well, according to a new study. Researchers from Penn State’s College of Information Sciences and Technology have found that existing CSC apps lack the functions to support the full diagnostic process of a traditional visit to a medical facility. Rather, they said, the apps can only support five processes of an actual exam: establishing a patient history, evaluating symptoms, giving an initial diagnosis, ordering further diagnostic tests , and providing referrals or other follow-up treatments. “One of the exciting aspects of this research has been its multidisciplinary nature. As an electrical engineer , I find it quite fascinating to work on designing and developing an optical diagnostic system as well as performing microbiology assays,” said Keren Zhou, the co-lead first author on the paper and a doctoral student in electrical engineering. I am a professional software developer, and founder of It’s FOSS. I am an avid Linux lover and open source enthusiast. I use Ubuntu and believe in sharing knowledge. Apart from Linux, I love classic detective mysteries. I’m a huge fan of Agatha Christie’s work.
A few decades ago, the first publicly available handheld phones were bulky and with bad reception. By the 90’s and with thanks to the electrical engineering developments towards GSM technologies, mobile phones soon did more than just make and receive calls. Today, it has become a race to the smallest, most multi-functional mobile phone. Headway in electrical engineering and the subsequent circulation of the science means more companies need creative individuals. And this is just to keep up with the competition. That’s not even taking into account the perks of such a world-changing occupation. Electronics engineering is a subfield within electrical engineering that deals exclusively with low voltage electronics systems that incorporate integrated circuits, semiconductor devices, transistors, and diodes and is related to computer engineering. The term electrical engineering is often used to refer to high voltage system engineering, often incorporating power generation and distribution systems in civil and industrial scale projects. Electrical engineering degree programs generally cover electronics engineering or offer it as a focus or concentration within the program. i think its wacky idea playing with pressing botton when to put to sleep,wake lough,sad or angry. they do not realise that person this human being. they should be by attorney fight for their rights for study them secretly. overtaking their lives and family life. whole family effected by it. what that person think its not person:s own thinking, only what botton controller wants you to think and do. As two of the most influential energy resources, phasing out them are unquestionably difficult. Coal-combustion and natural gas usage produce excess GHG, thereby warming up our globe. Portland, resolute to eliminating the two, will face challenges. The government will spend vast expenses on building more renewable power-plants to fill in the gap of losing coal and natural gas, and sadly, the economy will likely fall due to the massive spending and the lack of electricity. No changes come quickly, so Portland will have to endure a time when not adequate electricity is generated to power all infrastructure. Electrical engineering is centred around the study of electricity. However, what many people don’t realise is that it covers a variety of subjects and industries such as electromagnetism, control systems, telecommunications and power. Into the twentieth century electrical engineering broke into many fields in research and technology like electrical engineering or electronic engineering. The first being associated with large scale electrical systems like electrical networks power systems and the latter associated with smaller scale electronic systems like computers and small circuits. This lead to different areas of expertise for the electrician in installation, maintenance and repair including electricians specifically trained for certain appliances like TV repair. Towards the end of the twentieth century the electrician could be split into three different sections. These were divided into domestic, commercial and industrial electricians with each one having to learn particular skills to install, maintain, repair and test electrical equipment for safety. Safety became an important part of the electrician’s trade due to the risk involved not only for the electrician but for everyone involved with electrical appliances. Portable appliance testing was introduced.
This is such a great hub. Thanks for the information. I’m beginning to understand how great solar power is and this information just adds to that learning, thanks. It’s really amazing that we can use sunlight to generate energy and provide free use of home products like the common attic fan or any device that uses solar energy. That takes quite a lot of time, so Malovichko and his colleagues from the Skoltech Center for Data-Intensive Science and Engineering (CDISE) have proposed to approach this challenge in a different way. Their solution for the inverse EEG problem directly “backpropagates” measured signals from the skin inside the head down to the cortex. This requires reframing the whole task as a Cauchy problem, a type of mathematical problem that is known to be unstable for EEG: that means even slight deviations in the input, for instance, from unavoidable measurement errors, can significantly skew the result. Yet recent research has brought new approaches to tackling these unstable problems efficiently, and the scientists used them in their research. VMWare and Microsoft have a competitive relationship, that’s probably another reason why no Windows based development has occurred. This product has a high price tag, and is licensed per CPU. The ongoing support costs are also based on the number of CPUs. Drivers who listen to cell phone conversations are distracted even if they do not talk, exhibiting similar behavior as people who have been drinking. The study conducted at the Center for Cognitive Brain Imaging at Carnegie Mellon University in Pittsburgh used brain imaging to document that when driving and listening, activity in the parietal lobe, the portion of the brain associated with driving, was reduced by 37%. Another interesting use of cellulose in electronics is found in transparent cellulose films. As discussed before, cellulose can form networks of microfibers with proper preparation. Under the proper conditions, cellulosic microfiber networks can be made such that they are transparent to visible light. Transparent paper can be processed to tune light transmission from nearly 100% down to typical opaque paper. As transparent paper is made of the same robust microfibrillar cellulose as mentioned before, it remains a very durable material. Transparent paper could be a viable alternative to plastic films as an electrical device substrate in applications where flexible circuits are common, like conductive screens, OLED substrates, or solar cells. Interestingly, transparent paper could have a very promising future in conductive screen technology due to the lack of glare associated with cellulose films that seems always present in other film materials (Zhu et al., 2014).
