Computer designers can use an inexpensive pocket computer to collect data on how people use their products. Users carry the computer with them as they work; at random time intervals it prompts them to enter data about the task they are performing. This technique eliminates most of the tedium and disruption inherent in methods that require observers to keep a log of what they do. In addition, it retains the economy and simplicity of self-logging methods. We are using this system to evaluate users' interaction with computer hardware, software, and documentation.

The Difference

This article discusses the Performance of Free Software and Freeware in Telecommunication System. Software or software is a special term for data that is digitally formatted and stored, including computer programs, their documentation, and various information that can be read and written by a computer. In other words, part of a computer system that is intangible. This term emphasizes the difference from computer hardware. Making the software itself requires a "programming language" written by the programmer which is then compiled with the compiler application so that it becomes code that can be recognized by the hardware machine.

Many electronic devices have a network connection facility. Projectors today have network facilities to bolster its customer satisfaction in everyday use. By using a device that can be controlled, the expected availability and reliability of the presentation system (computer and projector) can be maintained to keep itscondition ready to use for presentation. Nevertheless, there is still a projector device that has no network facilities so that the necessary additional equipment with expensive price. Besides, control equipment in large quantities has problems in timing and the number of technicians in performing controls. This study began with study of literature, from searching for the projectors that has LAN and software to control and finding a number of computer control softwares where the focus is easy to use and affordable. Result of this research is creating asystem which contains suggestions of procurement of computer hardware, hardware and software projectors each of which can be controlled centrally from a distance.

Accompanying the proliferation of computers in almost every facet of life is an underlying risk to financial well-being related to computer system and data quality. The viability of a business often depends upon the continual and reliable operation of its computer system. The consequences of low-quality computer hardware and software are not infrequent or insubstantial. A recent report from the U.S. Department of Commerce states that total U.S. software sales in 2000 were approximately $180 billion (RTI, 2002). The report estimated that the lack of an adequate software testing infrastructure costs U.S. software users over $38 billion per year, principally through error avoidance and mitigation activities.

The development of commodity-off-the-shelf computer hardware components has allowed for the trend in high performance computing away from computer-system vendor proprietary hardware. A Beowulf computer system is a high performance computer assembled from commodity-off-the-shelf hardware and uses application programming interface libraries and open source operating systems to create a unified computing environment. In this paper, a Beowulf computer system is described and a performance benchmarking exercise is presented. The simulation is a benchmark problem relevant to hydrocode simulations and specifically simulates the high-speed impact and penetration of a long rod. Through this simulation study and a comparison to similar simulations performed on other computer systems, the price/performance advantage of a Beowulf system is demonstrated.

Legal Remedies

This chapter discusses various theories of legal liability related to computer system and data quality. Contract-based theories are discussed in detail, as most computer systems are acquired and data are accessed through some form of contractual relationship. Additional tort-based theories of liability are also discussed, particularly relating to publication of inaccurate data. As presented in this chapter, purchasers of defective computer hardware or software and users of inaccurate data have very limited legal remedies available. Further, the legal remedies that may be available are typically severely restricted by the contract through which the computer system is acquired or the data are accessed.

Quiescent Prominence

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.

Single Living Cells

Advances in digital imaging microscopy and in the synthesis of fluorescent dyes allow the determination of 3D distribution of specific proteins, ions, GNA or DNA in single living cells. Effective use of this technology requires a combination of optical and computer hardware and software for image restoration, feature extraction and computer graphics.The digital imaging microscope consists of a conventional epifluorescence microscope with computer controlled focus, excitation and emission wavelength and duration of excitation. Images are recorded with a cooled (-80°C) CCD. 3D images are obtained as a series of optical sections at .25 - .5 μm intervals.A conventional microscope has substantial blurring along its optical axis. Out of focus contributions to a single optical section cause low contrast and flare; details are poorly resolved along the optical axis. We have developed new computer algorithms for reversing these distortions. These image restoration techniques and scanning confocal microscopes yield significantly better images; the results from the two are comparable.
