The technologically advancing society is continuously challenging the limits of conventional materials and placing newer demands on material performance. Extreme and sometimes conflicting requirements are forcing us to engineer materials that are not possible by conventional alloying methods. Composite materials form a material system composed of a mixture or combination and are insoluble in each […]
The telecommunications industry has seen a rapid boost within the last decade. New realities and visions of functionalities in various telecommunications networks have brought forward the concept of next-generation networks (NGNs). The competitions among operators for supporting various services, lowering of the cost of having mobile and cellular phones and smartphones, increasing demand for general […]
The single most important property of elastomers—that from which their name derives—is their ability to undergo large elastic deformations; that is, to stretch and return to their original shape in a reversibleway. Theories to account for this characteristic high elasticity have passed through three distinct phases: (1) the early development of a molecular model relating […]
Homogeneous catalysts have played a key role in the production of petrochemicals and coal-derived chemicals since the 1960s. In the last two decades, transition metal catalysts have revolutionized synthetic organic chemistry, both in the laboratory and in industrial production. The use of homogeneous catalysts in polyolefin synthesis started in the 1980s and triggered enormous R&D […]
Client-side web app development has always been the poor cousin to server-side coding. This started because browsers and the devices they run on have been less capable than enterprise-class servers. To provide any kind of serious web app functionality, the server had to do all of the heavy lifting for the browsers, which was pretty […]
Otology and clinical achievements in dealing with middle ear diseases have historically relied on the valuable work of anatomists, beginning with the Renaissance and throughout the revolutionary era of temporal bone microscopic dissections. During the last 20 years, thanks to the advanced work and research of otologists, new knowledge of middle ear anatomy had great […]
Successful execution of any task always begins with planning. If your job involves the migration of your organization’s IT infrastructure to Microsoft Windows Server 2012, you need to prepare both your environment and yourself for this task. The success of an infrastructure-migration project depends on careful planning combined with meticulous execution. You need to start […]
Like any human language, C++ provides a way to express concepts. If successful, this medium of expression is significantly easier and more flexible than the alternatives as problems grow larger and more complex. However, you can’t just look at C++ as a collection of features; some of the features make no sense in isolation. You […]
THE GROWTH OF USER-DRIVEN CONTENT has fueled a rapid increase in the volume and type of data that is generated, manipulated, analyzed, and archived. In addition, varied newer sets of sources, including sensors, Global Positioning Systems (GPS), automated trackers and monitoring systems, are generating a lot of data. These larger volumes of data sets, often […]
A lot has changed since I first entered the photographic industry as a professional photographer and technical journalist. Some of the companies, both digital and traditional, that I used to know well are no longer in existence: there are also other companies that previously confined themselves to household electronics but now have a strong presence […]
Grammar is a very old field of study. Did you know that the sentence was first divided into subject and verb by Plato, the famed philosopher from ancient Greece? That was about 2,400 years ago! Ever since then, students all over the world have found it worthwhile to study the structure of words and sentences. […]
