The Web is evolving into a web of data or Semantic Web. Data will be encoded by Semantic Web languages like RDF or OWL according to many experts' visions. So, it is not difficult to envision data feeds will be also in the form of RDF or OWL. A big advantage of providing semantic data feeds, i.e. feeding data in Semantic Web standards, is that the data can then be readily consumed and reused by other computers.
CSV datafeeds are mostly being used within the affiliate marketing. Affiliate or so called publisher websites load the CSV file to load product information from online webshops. This way it is a lot easier to load thousands of product to the website. CSV is not like XML and is not as semantic but it does have a good basic structure. This file format can easily be created and loaded with any spreadsheet program like Excel.
A pocket-size reference that has all the fundamental data that engineers need in their daily work. Taping and drilling charts, hole coordinate charts with common sizes already worked out, speeds/feeds, material specs, drawing symbols and standards, CNC machine codes, plus much more. This book is also a very useful reference for students in engineering and drafting programs.
Perhaps the most explosive technological trend over the past two years has been blogging. As a matter of fact, it's been reported that the number of blogs during that time has grown from 100,000 to 4.8 million-with no end to this growth in sight.What's the technology that makes blogging tick? The answer is RSS--a format that allows bloggers to offer XML-based feeds of their content. It's also the same technology that's incorporated into the websites of media outlets so they can offer material (headlines, links, articles, etc.) syndicated by other sites.As the main technology behind this rapidly growing field of content syndication, RSS is constantly evolving to keep pace with worldwide demand. That's where Developing Feeds with RSS and Atom steps in. It provides bloggers, web developers, and programmers with a thorough explanation of syndication in general and the most popular technologies used to develop feeds.This book not only highlights all the new features of RSS 2.0-the most recent RSS specification-but also offers complete coverage of its close second in the XML-feed arena, Atom. The book has been exhaustively revised to explain:
A mathematical framework that describes learning of invariant representations in the ventral stream, offering both theoretical development and applications.
The ventral visual stream is believed to underlie object recognition in primates. Over the past fifty years, researchers have developed a series of quantitative models that are increasingly faithful to the biological architecture. Recently, deep learning convolution networks -- which do not reflect several important features of the ventral stream architecture and physiology -- have been trained with extremely large datasets, resulting in model neurons that mimic object recognition but do not explain the nature of the computations carried out in the ventral stream. This book develops a mathematical framework that describes learning of invariant representations of the ventral stream and is particularly relevant to deep convolutional learning networks.
The authors propose a theory based on the hypothesis that the main computational goal of the ventral stream is to compute neural representations of images that are invariant to transformations commonly encountered in the visual environment and are learned from unsupervised experience. They describe a general theoretical framework of a computational theory of invariance (with details and proofs offered in appendixes) and then review the application of the theory to the feedforward path of the ventral stream in the primate visual cortex.

Machining is one of the most important manufacturing processes, which remove unwanted material in the form of chips from a workpiece. Material removal operations are among the most expensive; in the U.S. alone, more than $100 billion were spent on machining in 1999. These high costs put tremendous economic pressures on production managers and engineers as they struggle to find ways to increase productivity.
Machining recommendations provided in this book cover turning since it allows removing more material per unit of time and consuming more power at the roughing operations than end milling, boring or drilling. Machining recommendations relate to cutting speeds, feed rates, and depth of cuts. Such recommendations depend on the workpiece material properties and the cutting tool material. Workpiece materials described in this book are the most commonly used grades of carbon, alloy, stainless, tool, and maraging steels. Cutting tool materials are cemented carbides, cermets, and ceramics.
A timely introduction to current research on PID and predictive control by one of the leading authors on the subject
PID and Predictive Control of Electric Drives and Power Supplies using MATLAB/Simulink examines the classical control system strategies, such as PID control, feed-forward control and cascade control, which are widely used in current practice.Â The authors share their experiences in actual design and implementation of the control systems on laboratory test-beds, taking the reader from the fundamentals through to more sophisticated design and analysis.Â Â Â The book contains sections on closed-loop performance analysis in both frequency domain and time domain, presented to help the designer in selection of controller parameters and validation of the control system.Â Continuous-time model predictive control systems are designed for the drives and power supplies, and operational constraints are imposed in the design.Â Â Â Discrete-time model predictive control systems are designed based on the discretization of the physical models, which will appeal to readers who are more familiar with sampled-data control system. Soft sensors and observers will be discussed for low cost implementation.Â Resonant control of the electric drives and power supply will be discussed to deal with the problems of bias in sensors and unbalanced three phase AC currents.
Researchers and industrial engineers; and graduate students on electrical engineering courses will find this a valuable resource.
