Hardware portability

Aluminum is used in the home as household foh (0.18 mm thick), cooking utenshs (the first commercial use of aluminum), refrigerators, air conditioners, appHances, insect screening, and hardware. It is also used for toys, sporting equipment, lawn furniture, lawn mowers, and portable tools. In many of these apphcations, anodized or colored coatings are employed for decorative purposes. 

Computers may be used for noise analysis when connected to dedicated hardware devices. One machine incorporates a narrow-band analyzer, octave and one-third octaves with all the features of an environmental noise analyzer. These devices cost much less than purchasing all the dedicated instmments separately. They may be obtained in portable form but are rarely weatherproofed for outdoor use. 

The NIPALS algorithm is easy to program, particularly with a matrix-oriented computer notation, and is highly efficient when only a few latent vectors are required, such as for the construction of a two-dimensional biplot. It is also suitable for implementation in personal or portable computers with limited hardware resources. 

Except for certain library routines used to drive the interface hardware and some system specific routines from the system library, all of the routines are written in a dialect of FORTRAN IV and they are sufficiently modular and portable to be adaptable to other combinations of computers and chromatographs.

Many government and commercial impairment testing systems can be implemented on standard commercially available personal computer platforms (e.g., PC, Macintosh). Despite software and hardware advancements that have minimized the differences across platforms, it is still important to consider carefully the hardware and software requirements needed to support a system, as these specifications may have important implications for the accuracy of stimulus presentation and the precision of performance measures. In addition, there may be differential costs associated with the hardware and software specifications. The speed of the computer processor is one important specification that requires careful consideration. Other concerns include the amount of memory that is needed to present the test and record the results, the manner in which the data are to be stored, the size and portability of the computer, and the video-display requirements. Some systems... 

Figure5. Organization of image processing software. The three higher-level software should be portable so that they can be used for any future hardware architecture.

The painting crew used a 5-ft. diameter by 6-ft. tall, portable, vertical, pressure vessel which was designed for 125 psig (860 kPa gauge) internal pressure. After a routine fit for service inspection, the industrial-sized vessel and trailer were brightly painted. A decision was made to renew the hardware on the top-mounted, ten-inch charging nozzle. 

The other required piece of hardware for small, portable Raman spectrometers was a miniature laser. Diode lasers have become the mainstay for CD players and for fiber optic communication systems thus they are readily available as Raman sources. The instrument shown in Fig. 2-29 integrates a... 

At the next level, the subroutine library that the user works with remains functionally constant, but its internal structure will directly take into account differences in hardware. This allows some portability, but puts the burden of support for different devices on the system/1ibrary manager. 

Code developers are increasingly inspired to write their programs to be portable between several machines, even from microcomputers to large computers and vice versa. Software for minisupercomputers and supercomputers may be optimized for a particular machine, in which case the hardware vendor may be an additional source of information about a program. 

Until the late 80 s, the software development was very much curtailed by the limitations of hardware, where the size of the memory was the most critical factor. Today, about a decade later, the most critical aspect for large scale parallel MD simulation is not the hardware, but the software. Coping with increased problem and algorithmic complexity, as well as, varying hardware platforms is a daunting task. Adding the requirement of optimal use of hardware resources makes the development or modification of an efficient and portable parallel MD simulation software a formidable challenge. 

In the final section, you learned the differences between portable computer systems and desktop PC systems. The A+ exam tests your knowledge of the hardware unique to portable computers systems. You learned how these unique components work. For example, you learned how the different types of LCD displays worked. You also learned how power is supplied to portable computers through batteries and AC adapters. 

Biotrace International (Bridgend, UK) and was mounted so that the light measurements could be made directly from the reaction chamber. As a developmental iteration the National Instruments control hardware was substituted for electronic control components integrated into a light tight box together with the fluidic block. A compact controlling computer was built in order to make the device portable. 

Due to the simplicity of hardware requirements and small volumes, even a gel documentation system could be used for high throughput screening. Further, BART is an ideal format for portable devices using NAATs to detect pathogens and GM. 

It is portable to different hardware, operating systems, and network locations.
