IntellBatt, a novel multicell battery design, exploits cell characteristics to increase battery lifetime, ensure safe operation, and improve performance. Simulations using Li-ion cells in a portable DVD player show a 22 percent battery lifetime enhancement.
Software instrumentation provides the means to collect information on and efficiently analyze parallel programs. Using Pin, developers can build tools to detect and examine dynamic behavior including data races, memory system behavior, and parallelizable loops. Pin is a software system that performs runtime binary instrumentation of Linux and Microsoft Windows applications. Pin's aim is to provide...
Asynchronous JavaScript and XML (Ajax) is a collection of technologies used to develop rich and interactive Web applications. A typical Ajax client runs locally in the user's Web browser and refreshes its interface on the fly in response to user input. Using this method with the AWS-ECS let us automatically generate test sequences and detect two deviations of their service implementation with respect...
Multicore and multithreaded CPUs have become the new approach to obtaining increases in CPU performance. Numeric applications mostly benefit from a large number of computationally powerful cores. Servers typically benefit more if chip circuitry is used for maximizing throughput via multiple threads per core.
Auditors validate information about organizations and their business processes. Reliable information is needed to determine whether these processes are executed within certain boundaries set by managers, governments, and other stakeholders. Violations of specific rules enforced by law or company policies may indicate fraud, malpractice, risks, or inefficiencies. Traditionally, an audit can only provide...
This essay considers predictions of the effect of digital technology on the English language, contrasts language content or information with language media or data, considers traditional dimensions of linguistic data and information, contrasts face-to-face conversation with mediated conversation like Twitter and Facebook, looks at alphabetic and phonetic shorthands in the context of digital social...
Regular expressions, or regex, are a common choice for defining configurable rules for data parsing because of their expressiveness in detecting recurrent patterns and information. For many data-intensive applications, regex matching is the first line of defense in performing online data filtering. Unfortunately, few solutions can keep up with the increasing data rates and the complexity posed by...
Architecturally diverse systems can improve streaming application performance by orders of magnitude, albeit with enormous programmer effort. To simplify the programming of such systems, we have constructed the Auto-Pipe application development environment, which supports the flexible mapping of application components onto computational resources and the automatic delivery of data between these computational...
Due largely to the rise of social networking, the Internet constantly receives large quantities of new material that traditional search technology won't find in real-time. Real-time search addresses this shortcoming.
The public perceives the Web as a wildly uncensored medium, the embodiment of complete freedom of expression (for good or bad). In reality, information on the Web is not as uncontrolled as it may appear. According to the OpenNet Initiative (www.opennet.net), more than 40 countries actively filter Web access- selectively blocking content to a billion Internet users worldwide-and many others are considering...
Computer science holds a special position among engineering disciplines. First, it is a relatively new field characterized by underlying exponential performance improvements. Second, its subfields include modeling all other engineered, natural, and human systems. Over the past 70 years, computing practice and education have had to adapt to rapidly changing technology, applications, and the evolution...
