ESR Meter

Because measuring an electrolytic capacitor with an analog or digital capacitance meter can MISLEAD a technician into believing that a defective capacitor is good. This can waste your precious time and you are unable to repair the equipment. Which means you can’t charge your customer! If you don’t test for ESR on the capacitor, you will always miss the bad capacitor. Normally, these bad capacitors have high ESR reading which your normal multimeter or digital capacitance meter can’t measure. Only by using the ESR meter, you will be able to measure the ESR on the capacitor and you will not be fooled by capacitors with bad ESR. ESR meter can even work IN-CIRCUIT, which means you don’t have to solder out the capacitor in order to measure it using normal capacitor tester, which would not be accurate anyway.

Do you know that ESR meters can perform other wonders besides checking the ESR of a capacitor? Some digital ESR meter have the features of checking:

  • Low ohms resistor such as 0.22 ohm, 0.33 ohm and etc.
  • Horizontal yoke coil winding of a picture tube, inductor and primary winding of a transformer – If a shorted turn is present, the inductance drops dramatically and the meter will show the ohms reading.
  • Horizontal output transistor (HOT) in a monitor or TV – If an open-circuit reading is obtained, the short-circuit is elsewhere. If the short-circuit remains, the transistor is faulty.
  • Short-circuit in the track, usually trace to the components – You can use the ESR meter to locate short-circuits on printed circuit boards by measuring the actual track resistance. If the reading increases as you probe further along the track, you know you’re going in the wrong direction!
  • Speakers, amplifier etc – The pulses have a fast rise/fall time, so it would probably make a crude RF signal injector as well.
  • The condition of both the normal and rechargeable batteries – Flat and faulty battery will have high ESR.

Creating A Website for Your College

Comprehensive Prospectus

This is one of the pivotal element of any educational site. Online prospectus cones as a good alternative to the printed booklets that are published in huge amounts for distributing to the prospective students. It serves the same purpose but in a more defined way. Students, parents or anyone can access it from their own desktops or mobiles, and can even get it downloaded in PDF format.

Brand consistency

If you are making a website for your college, make sure that it well represents your college as a brand. It the first thing about your college that the new students, alumni or any parents will get to see. It is also the single medium for them to interact with the college’s management for any queries. So, precisely, you need to sure that site goes well with your branding and it promotes the content that reflects your institution’s mission, vision and values.

CRM integration

A website is incomplete with the capability to record the number of new visitors, session times, bounce rates and so forth. In other words, it’s essential to integrate your website’s CMS with a robust CRM (Customer Relationship Management). Through it, you can save all valuable data of the students, help them access their data when needed, fetch information from other departments, interact with admin members and so on.

Organised layout with refined content

Clearly, this is the era of content. You need to use it for thrusting your brand value and create an everlasting digital presence of your college. While getting your website developed, make sure you have a structured layout with refreshing and purposeful content. For educational websites, owners should take care in curating the content taken from across the web, so that they interest the layman as well as students.

Intuitive and Robust Search feature

There’s no fuss about the essentiality of this feature in an educational website. While most visitors to an education institute’s site are the prospective students keen to take admissions, it needs to be convenient and faster for them to find the information they need. Whether it is about a course, fees and charges, institute’s learning spheres, department’s information, faculty information etc. they should get it all from respective links of the website.

Printer Ink Cartridges

In 1984 ink jet printers and printer cartridges were introduced. Printing documents was now easier and so was changing printer cartridges. After years of changing ribbons, adding toner ink to reservoirs within the computer.

The dot matrix method used a ribbon. The industry found new ways to make printing easier and more convenient. There is the drop on demand method where the ink squirts onto the paper through tiny nozzles. The amount of ink dropped the page is controlled by the software driver that controls which nozzle fires and when.

By 1990 ink jet print cartridges was widely accepted. Printer cartridges can now print in color as well as in black and white for document. Inkjet printer cartridges can print on just about any sized paper, on fabric and on film. Ink jet printers are used in a variety of settings worldwide and is a popular choice for printing.

Each brand of printer uses a specific type of cartridge. Ink jet cartridges are given an identification number and the models that can use this particular cartridge, is listed. There are a wide variety of cartridges available and you should check your printer’s manual to see exactly what cartridges are available to you.

If you are trying to save money, you can purchase refill kits that allow you to fill the cartridges yourself. Not everyone is a fan of these kits however, the quality of the printing isn’t as good, and in some cases the cartridges when re-installed can fail to operate.

You can get reconditioned and refilled cartridges from some retailers and sometimes from the manufacturer. Compatible cartridges are cartridges that are made according to the exact specs of the original manufacturer. The drawback here is that not every cartridge has a compatible one.

In choosing a printer check the type of cartridge it will use. You will need to determine if the cartridge is appropriate for the type of printing and the volume of printing you will be doing. You will have to do some research and you can find much of this information on the internet, through the manufacturer or through stores that deal in the particular printer you are looking at.

Discount ink cartridges are available online. All you have to do is type ink cartridges or printer cartridges into your search engine. Some sites offer amazing discounts. Again you are going to have to search for the deal that is best for you. Pay attention to the cartridge top when purchasing them. Check the sides of the box for a list of models the cartridge will work in.

There is a time line below that has some really interesting facts.
This would make a great list of answers for a trivia game. I cannot imagine the hard work that created the ink jet printer cartridge, as we know it. It is easy to understand why cartridges are expensive.

  • 1452 – Gutenberg used oil-based ink, moveable type, and an old winepress to make the first printing press.
    Martin Luther began the Protestant reformation making extensive use of the printing press.
  • 1714 – The typewriter was born. Schematics that were done by Mills were discovered however, there is no proof that any typewriters were actually made.
  • 1874 – Christopher Sholes, Samuel Soule, and Carlos Glidden made a keyboard that became known as the “qwerty” because of the first five keys on the top row of the keyboard.
  • 1894 – Franz Wagner developed a typewriter that is very similar to the ones made today. He created a design that let the typists watch as they were typing. Previously, paper would go through a roller as you typed and you could not see what you typed until you were done.
  • 1897 – Underwood (by John Underwood) was the prototypical typewriter of its day.
  • 1939 – Charles Carlson developed electrography, which is the first dry writing technique developed in the United States.
  • 1949 – Haloid Company began to commercially developed electrography for the first time.
  • 1959 – Xerox 914 hit the market and forced other businesses to update their communication systems.
  • 1969 – Xerox first introduced dry printing (laser printing) by Gary Starkweather.
  • 1078 – Xerox put out the world’s first business laser printer the Xerox 9700. It copied documents at the speed of 120 ppm (pages per minute)
  • 1979 – The IBM 3800 could print out 20,000 lines per minute.
    1980’s – The use of toner cartridges became obsolete.
  • 1984 – Hewlett-Packard released the first home-based desktop laser printer.

ArchiCAD vs Revit

Revit by Autodesk and ArchiCAD by Graphisoft are the two biggest players in the market. This comparison between ArchiCAD and Revit will help architects, owners and contractors to make а more briefed decision.

ArchiCAD is the first BIM software for architects, created in 1984. Offering a suite of tools for building design and engineering, this software enables seeing the project through engineering and visual design of building`s interiors and exteriors. On the other hand, Revit is 4D BIM-capable tool which helps us to plan all aspects of a building project, from design to construction and beyond. Realized in 2002, this software can be used by architects, builders, engineers, project managers and more.

User Interface

ArchiCAD`s user interface is maybe the first thing that users are praising it for. It`s clean and sleek and that`s maybe the reason why ArchiCAD has an easier learning curve, especially for designers. While the user interface can be customized in a number of ways, it has slightly less flexibility than its opponent. Revit features a user interface that is highly customizable, supporting multiple approaches for using the software. It is a little bit complicated, because of its medium learning curve. However, Revit offers greater level of flexibility to designers and architects.

Conceptual Design

Concept design in ArchiCAD is a fairly user-friendly, enabling push/pull modelling, instant and customizable geometry and smart multiple extruding. Similar, Revit features a conceptual design which provides flexibility in the earliest stages of a project. This allows you to create geometry that later can be integrated into your BIM project.


Revit features a wide range of views from which to approach your design, such as wireframe and transparent surface. Each view can be manipulated and controlled in a particular project and can be assigned to the overall view or specified to a category or element. ArchiCAD has similar visual styles as Revit, but don`t have the capacity for applying views to specific elements.


Both, ArchiCAD and Revit have intensely large suite of tools for rendering. They can produce photorealist images of the interior and exterior of your project. The Ray Trace is a photorealist rendering mode that allows panning and zooming with your Revit model. When using this visual style, the rendering starts at a lower resolution but quickly increases its fidelity. Thus, you can set lightening, photographic exposure and background. ArchiCAD features CineRender, similar tool to Ray Trace which allows you to change the light, shadow, texture, brightness and more.


Revit and ArchiCAD can both import and export IFC files. Furthermore, they are capable of importing and exporting all common file types, including 3D models, 2D drawings and other CAD file types.

Web Development Frameworks

  • AngularJS: This Google’s baby deserves to be in the top position of web frameworks. This framework is designed primarily for single page application. The current version of AngularJS is 5.0. It has enhanced its features in a short span of time to meet the demand of the market. So what is this framework is all about? AngularJS is an open-source and structural framework for dynamic web applications. The new version of AngularJS has been released with advanced features and bug fixes. In simple terms, AngularJS is smaller, Faster and easy to use.
  • Laravel PHP: Laravel is a framework of PHP (Hypertext Processor). It is an open-source (Zero Licensing Fee) framework with Model-View-Controller (MVC) architecture. 2011 is the year of Laravel’s inception, since then it has given promising outputs for the developers. Laravel is a user-friendly web framework, which helps to develop the application with an elegant syntax. The robust features of Laravel have made it to the top list in PHP frameworks and second in web framework list. The MVC features, Beautiful templating, Rapid pace of development, RESTful Services and better code foundation are some of the known features of Laravel PHP.
  • React.JS: This is a front-end JavaScript library developed by Facebook. Most of the major applications are currently running on React.JS. The applications which required data changes constantly are using React.JS. Because it will update and render the right components when the data changes. It is used extensively in developing user interface (UI) of the web application. You can develop enclosed components that manage their own state, then compose them to make complex user interfaces. It allows us to create reusable UI components. The current version of React is 15.0.
  • Symfony PHP: Symfony is a framework of PHP. The Symfony framework is built on model-view-controller (MVC) architecture. The current version of Symfony is 4.0. With Symfony, developers need not write the repetitive coding and they can control the coding very well in this framework. The Symfony components consist of decoupled and reusable components on which best PHP applications are developed. Drupal, eZ Publish are some of the examples of Symfony PHP
  • ASP.NET MVC: ASP.Net is a web development framework developed by Microsoft. You can develop dynamic websites using ASP.Net MVC framework. ASP.Net MVC is an alternative to ASP.Net Web forms pattern. ASP.Net MVC is a lightweight framework which is integrated with ASP.Net web forms features. The developer can have full control over the application as it does not use view state or server-based forms. You can use any of this web technologies ASP.Net Web forms and MVC based on your need. The features and components of ASP.Net MVC make it easier for the programmers to develop the complex applications easily.

Buy Computer Memory

When Upgrading Your Operating System

Each time I upgrade my operating system, I find that I need to buy more memory. Your operating system is a huge memory hogger. Windows XP , for example, requires at least 512 MB RAM to run smoothly (at least on my PC). Windows 2000 needs at least 256 MB RAM. Always check the operating system manufacturer’s documentation carefully – they always tend to understate memory requirements.

When installing new applications: Business software like Microsoft Office, video editing applications like Adobe Premiere Pro and games like Half-Life 2 really need a LOT of memory. Some will refuse to run if they find your memory lacking. Other applications will run but will crawl like a snail. Newer software these days assume you have a huge amount of memory. Again, check the manufacturer’s documentation carefully for memory requirements.

When Installing Multimedia Cards

Two types of cards come into mind – video cards and sound cards. Video cards have a built-in memory but they also consume main system RAM. Don’t be fooled by that fancy video card that says it’ll deliver fantastic 3D graphics performance. Video cards depend a lot on your main system RAM. Without sufficient memory, the video cards will still perform poorly even if they are the latest and greatest versions (the ATI Radeon 9800 Pro comes to mind).

When Adding Computer Peripherals

If you add a printer or scanner to your system, you should also consider buying more memory. Printers consume system memory particularly when printing huge files. Scanners consume memory when handling large image files.

When Your Hard Disk Starts ‘Chugging’

In general, you can tell whether you should be buying more memory by listening to your hard drive. Yes, by listening to your hard drive. If it makes a long drawn ‘chugging’ noise whenever you copy or edit large files, you can be sure you need a memory upgrade.

You see, when your system is low on memory, it borrows space from your hard disk to make ‘virtual memory’. This process is called ‘paging’ and it’s very, very slow and irritating . Get that memory upgrade and avoid this problem at all costs!

How Much Memory Do You Need?

Depending on the type of software applications you are using, the amount of memory you need will differ. As a bare minimum, computers these days need at least 256 MB of RAM.

Refer to the list below to see how much memory you will need based on the type of software you use.

  • Administrative: Word processing, email, spreadsheets, surfing the web, general gaming, not many applications open at once. Get 256 MB to 512 MB of memory.
  • Executive/Professional: Word processing, email, spreadsheets, presentations, videos, photos, surfing the web, general gaming, several applications open at once. Get 512 MB to 1 GB of memory.
  • Graphics Design/Software Development: 3D CAD software, enterprise programming suites, simulation or modeling software. Get 1 GB or more of memory.

About Combination of Nanotechnology

At today’s time, nanotechnology is considered as an important and significant role that creates great impact on the lives of human being. A research has been conducted which shows that nanotechnology is a combination of engineering, science and technology which considers the measurement of 1 to 100 nanometers. It sis found that many molecules and atoms behaves differently at Nano-Scale.

This is considered as the most rapid expanding field. Engineers and scientists achieve great success in the creation of materials at Nano-Scale that make use of various advantages with Engineering Colleges that enhanced properties like light weight, high strength and increased conductivity of electricity and chemical reactivity that can be compared with large-scale equivalents.

There are various ways of technology that are gradually impacting the lives of human beings. Some of them are as follows:

  • Various small, fats or powerful computers consumes less power and contains long-lasting batteries. Carbon nanotubes make use of circuits that is important for the maintenance of computer power growth that allows various laws to continue.
  • There are several equipment that is more functional, faster and more accurate for medical diagnostic system. Chip technology enables care testing in real-time which allows the delivery of medical care. Nano materials implant the improvement of resist and wear infection.
  • Pharmaceutical products contain Nano-Particles that improve the particle absorption within the body and enables easy delivery through combination of various medical devices. These devices help in the delivery of chemotherapy drugs to specific cells that also includes cancer cells.
  • Improvement in vehicle fuel efficiency and corrosion resistance with the building of vehicle parts form Nano composite materials carries slight weight, are more stronger and are chemically resistant than metal. These Nano filters helps in the removal of airborne particles that comes from the air before its reaching to combustion chamber. It can also help in the improvement of gas mileage.

Shopping Cart Software Tips


Instead of looking up competitors one by one, just add a couple of Price Comparison sites to your Favorites list and you can easily compare product pricing from several stores at once. This will save you a lot of time. Do note that some of the information on those sites might be outdated if the product information feed is not updated.

However, it is still a good guide as shoppers would be referring to those sites as well.

Offers And Promotions

This one is easy, just subscribe to newsletters from your competitors. Remember to use an email address from Yahoo! or Gmail and not one from your store’s domain.

You can learn a lot from store newsletters. Apart from what products they have on offer, you can also find out when they start their promotions in relation to festivities and events. Have a close look at their Call To Action (CTA) images and text. Do they make you want to click on them once you have read them?

Once you have taken note on what a good newsletter should contain, you can use your shopping cart software newsletter broadcast feature to send out your own newsletters.

Auto Responders

Most shopping cart software now come with auto responders. The tricky thing about auto responder email is getting people to open it once they see it in their in box. The key lies in the subject matter. Much has been written about how to write compelling them but there is no surefire way.

Many stores use built-in ecommerce software auto responders to try to recover some of their aborted orders. Well crafted auto responder email can actually help convert up to 30% of aborted orders. If you want to learn how to craft an effective auto responder email for aborted orders, go to competing store and abort an order. You should receive an email within 24 hours.


If you would like to find out what keywords your competitors are targeting, you need to download a plug-in for Firefox called SEO for Firefox. You can then use tools like SEO XRay to scan a competitor’s page and find out which keywords are being targeted.

You can also use the Traffic Value link on your own search result to reveal your most popular keywords and your closest competitors. You can do the same by clicking the Traffic Value link on your competitor’s search result to get the same kind of information.

You do not have to target the same keywords as your competitors. It may prove to be more effective if you target keywords which your competitors are not ranking highly for.

Info of Predictive Analytics

Simply a decision-making tool, predictive analytics is used in a variety of trades. For example, an insurance company may use the tool to determine the probability that they will have to pay out for a future claim. The determination of probabilities is based on a current risk pool of similar policyholders and past events that have led to payouts.

Marketers use the tool to ascertain how consumers react to the overall economy. They use the result when they plan out new campaigns. They also use this tool to determined changes in demographics to determine if their current mix of products will induce customers to make a purchase.

In addition, retailers can use it to achieve competitive advantages. For example, predictive analytics can assist companies that offer many products to sell additional products to certain customers. It helps retailers retain customers. One study found that a 5% increase in customer retention rates translates to 25% to 95% of increased profits. Moreover, it can help stores target customers.

Traders of securities use predictive analytics to study an assortment of metrics based on past events so that they can decide whether or not to buy a security. In addition, the tool assists traders to forecast future price movements based on historical data.

It is also an ideal tool for credit scoring, which is used in the field of financial services. In this case, predictive analytics uses a customer’s credit history, loan application and customer data to rank customers’ likelihood of making future credit payments on time. Moreover, Financial institutions use it in their collection activities. They know that a lot of their resources are wasted on customers who will most likely not pay their bills. Predictive analytics can help financial institutions to develop appropriate strategies for each customer increasing payments while reducing collection costs. It also helps financial institutions in identifying high-risk fraud candidates.

The tool of predictive analytics can also be used in telecommunications, travel, healthcare, child protection, pharmaceutical, planning and other fields.

For example, in child protection, child welfare agencies have started using the technology to identify high-risk cases.

In healthcare, predictive analytics is being used to determine who is at risk of developing particular diseases including diabetes, asthma, heart disease, and more. It is also used to support decision-making when treating a patient.

The telecommunication industry is using the tool to better understand customer behavior, enhance customer experience, and be proactive in handling customer issues.

Predictive analytics helps the travel industry offer customers recommendations that include what airline tickets to buy and hotels to book, and sensors in planes can anticipate upcoming problems that can then be repaired before they become catastrophic.

Pharmaceutical companies are using predictive analytics to assist them in discovering new drugs and to minimize negative outcomes.

It is obvious that machine learning can provide a plethora of assistance to any type of business regardless of the field.

One of the many companies that are now promoting predictive analytics is WorkFusion. The software company shows how any large or small business can leverage all forms of automation including predictive analytics into their business operations.
