Capacitor banks installed to increase efficiency, reliability and power quality Zurich, Switzerland, Dec.21, 2010 – ABB, the leading power and automation technology group, has won an order worth $39 million from the Saudi Electricity Company (SEC), Saudi Arabia’s national power transmission and distribution provider, to improve the efficiency of power transmission and distribution in the [...]
Outline A proximity sensor can detect metal targets approaching the sensor, without physical contact with the target. Proximity sensors are roughly classified into the following three types according to the operating principle: the high-frequency oscillation type using electromagnetic induction, the magnetic type using a magnet, and the capacitance type using the change of capacitance. KEYENCE [...]
Electrical Network comprises the following regions: 1 – Generating Stations. 2 – Transmission Systems. 3 - Distribution Systems. 4 – Load Points. Functions of a Substation 1 – Supply of required electrical power. 2 – Maximum possible coverage of the supply network. 3 – Maximum security of supply. 4 – Shortest possible fault-duration. 5 – Optimum [...]
Before the advent of solid-state logic circuits, logical control systems were designed and built exclusively around electromechanical relays. Relays are far from obsolete in modern design, but have been replaced in many of their former roles as logic-level control devices, relegated most often to those applications demanding high current and/or high voltage switching. Systems and [...]
Design Consideration for Optical Fiber The Design and production of optical fiber cable is similar to the design and production of copper cable. The principle difference arises from the properties of the conductors themselves. Design Consideration In the design of optical fiber cable, special care must be taken that fiber is: Not bent too much, [...]
The Meta Tag Trifecta, the three hit combo, the three stooges of SEO, the three basic prinicpals of onpage optimization. Its easy, its quick, and its something everyone can do (at a low cost) to optimize thier web pages. 1) URL 2) Title Tag 3) Header Tag Thats right, make sure the main keyword assigned [...]
The Technical Report (TR) is a common written form through which computer scientist communicate their findings. Each TR should have a focused topic that is developed logically along some clearly identified perspective. The major components of a TR are title, author information, date, keywords, informative abstract, body, acknowledgments, references, and appendices. Typically, the body is [...]
The basic principle of technical writing is simple: Tell them what you’re going to tell them. Tell them. Then, tell them what you’ve told them. Why am I telling you this? Because, like it or not, documentation is part of programming. Good documentation will make your life substantially easier. Consider this – even if you [...]
Microsoft Security Advisory is reporting that a new exploit has been found in Internet Explorer and that users may immediately take notice to ensure a secure environment on their PCs. As by Microsoft: Microsoft is investigating a privately reported vulnerability in Microsoft Video ActiveX Control. An attacker who successfully exploited this vulnerability could gain the [...]

In addition to on-page factors, search engines are increasingly using off-page factors to calculate relevance. This is because off-page factors are more difficult to manipulate artificially. The most important off-page factor is link popularity. Others include social media marketing, link text, link community and click popularity. Off-page optimization involves ensuring that these elements are in [...]
Search engines use several factors in their ranking algorithms, one of which is on-page optimization factors. These are elements which actually appear on the page (such as page title, headings and body text) and contribute to the engine’s assessment of the subject matter and relevance of the page. On-page optimization involves ensuring that these factors [...]
