Computer software hardware array

Although not yet available, it is likely that Web-based performance testing systems will become available in the near future. Web-based systems will permit selected tasks to be presented on computers equipped with appropriate Web browser software. Hardware requirements include Internet access and appropriate memory and software to support Web-based applications. Depending on the design of the Web-based system, it is could be possible to tailor the specific tasks presented for the performance testing system from a menu of options. Alternatively, testing systems consisting of a standardized array of tasks can also be chosen. As such, the start-up costs of Web-based systems should be lower than with personal or handheld computer systems. Subject identification, date, and time can be recorded at the start of a test, and data from multiple subjects and test occasions can be stored in a central file for easy access to the data. 

Almost all applications programming in chemistry, and structural chemistry in particular, is performed in the FORTRAN language and the molecular mechanics calculations for which this hardware/software design exercise was undertaken is no exception. There are two problems which must be solved in order to build a FORTRAN microcomputer system with good scalar and array computational performance and these are firstly, the design of an efficient scalar processor with a transparent FORTRAN interface to the hardware and secondly, the design of an efficient AFPP,... 

Computations with all of the algorithms used in conformational analysis have been greatly facilitated by continual software and hardware developments. Among these are the use of array processors145 and parallelism.146 Implementation of parallel processing is currendy a very active field. 

Thus far, we have given a brief account on the technological development of the diode-array detector. Its applications offer several advantages to the user, which have been made possible primarily by the current computer hardware and software that are available on the market. Data acquisition and analysis are computer driven. The information acquired from the diode array can be analyzed to tailor the user s preferences. This area represents an emerging field and further advancements in analytical software tools will ultimately determine the true potential of diode-array detection. 

The third difference is that the products commercialized by the two sets of industries were dramatically different and directed toward different markets. Consumer electronics and computers transformed the ways of communication through sound (audio), sight (video), and manipulation of information (computers). Their products required two sets of hardware devices, one for transmission and the other for reception, with software to process the information within both and that flowing between them. The mature chemical and pharmaceutical industries, on the other hand, utilized the new scientific knowledge to create a vast array of new materials and medicines that replaced natural ones—metal, wood, and other organic products—that... 

Computer networks consist of the hardware and software needed to support communications and the exchange of data between computing devices. The computing devices connected by computer networks include large servers, business workstations, home computers, and a wide array of smart mobile devices. The most popular computer network application is e-mail, followed by exchanging audio and video files. Computer networks provide an inliastructure for the Internet, which in turn provides support for the World Wide Web. 

So far we have performed detailed studies for flow over isolated bodies, for example, curved fractures, shale arrays, and fractured boreholes. Here we will focus on steady and transient-compressible reservoir-scale flows produced by multilateral well systems. Because their topologies are not simple, we turn to computational methods. We will highlight problems that arise in reservoir simulator development, and importantly, we will describe a recently developed, three-dimensional algorithm that is very robust, numerically stable, exceptionally fast, and extremely accurate, and now available to the user community. Engineering implementation is an objective of the work oil companies want practical solutions that optimize operations, profits, and time value of money. The model provides tools that evaluate what if production scenarios, infill drilling strategies, and waterflood sweep efficiencies. In addition to being accurate, the solutions require minimal hardware, software, and costly human resources.

A systematic comparison of the methods should include the simulation of the several (the more—the better) test problems by these methods running on the same hardware. Such comparisons were performed for dielectric particles, see, e.g. Refs. [20-22], but they are not relevant for the plasmonics. On contrary, in plasmonics such comparisons are very rare. We can cite three examples, which both considered a single specific scattering problem, making it hard to generalize the conclusions. In particular, the FDTD and the FEM were compared for computation of near-field around 50-nm silver cube interacting with 600-nm plane-wave [12]. Accuracy of the FEM was worse than that of the FDTD but still satisfactory. The FEM simulation required 4 hours on a single 3.4 GHz processor, while FDTD—8 hours on 256 double-core 2.6 GHz processors. Another comparison [14] addressed the DDA and the FIT (the latter implemented in the commercial software) for simulation of refractive index sensitivity of rhombic hybrid Au-Ag nanostructure array. Both methods obtained the same value of sensitivity, but the DDA was faster (not specified how much).
