Operating systems research has traditionally consisted of adding functionality to the operating system or inventing and evaluating new methods for performing functions. Regardless of the research goal, the single constant has been that the size and complexity of operating systems increase over time. As a result, operating systems are usually the single most complex piece of software in a comput...

OBJECTIVES To determine the applicability of a computer-aided diagnostic system strain elastography system for the classification of breast masses diagnosed by ultrasound and scored using the criteria proposed by the breast imaging and reporting data system ultrasound lexicon and to determine the diagnostic accuracy and interobserver variability. METHODS This prospective study was conducted b...

As computer software has become more complex in response to increasing demands and greater levels of abstraction, so have computer operating systems. In order to achieve the desired level of functionality, operating systems have become less flexible and overly complex. The additional complexity and abstraction introduced often leads to less efficient use of hardware and increased hardware requi...

The NetWare operating system is designed specifically to provide service to clients over a computer network. This design has resulted in a system that differs in several respects from more general-purpose operating systems. In addition to highlighting the design decisions that have led to these differences, this paper provides an overview of the NetWare operating system, with a detailed descrip...

Operating system is the core course of the specialty of computer science and technology. To understand and master the operating system will directly affect students’ further study on other courses. The course of operating system focuses more on theories. Its contents are more abstract and the knowledge system is more complicated. Therefore, combined with teaching practice, the author puts forwa...

Though program verification is known and has been used for decades, the verification of a complete computer system still remains a grand challenge. Part of this challenge is the interaction of application programs with the operating system, which is usually entrusted with retrieving input data from and transferring output data to peripheral devices. In this scenario, the correct operation of th...

SLAC probably has accumulated more high power klystron operating hours in the delivery of beams for physics research than ani other laboratory in the world. Operating data has been logged by hand, and search of this data for klystron performance statistics is time consuming. When the new 65 MW klystrons for the SLC were planned, a computer based interlock and data recording system ias implement...

By interconnecting high-volume, standard computers, system architects can construct a high-performance, modular, parallel system, called a cluster,1,2 at a much lower cost than a specialized system. In addition, with a standard operating system running on each computer, or node, a cluster can cleanly survive the failure of an individual computer, disk, network, or other subsystem. A cluster can...
