Methods of decomposing the nonbonded force evaluation fall into two classes, spatial decomposition [15] in which atoms and their interactions are divided among processors based on their coordinates, and force-matrix decomposition [16] in which the calculation of the interaction between a pair of atoms is assigned to a processor without considering the location of either atom (Fig. 1). Spatial decomposition scales better to large numbers of... 

Electronic Controllers Almost all of the electronic process controllers used todav are microprocessor-based devices. These processor-based controllers contain, or have access to, inpuLoutput (I/O) interface electronics that allow various types of signals to enter and leave the controller s processor. The controller, depending on its type, uses sufficient read-only-memoiy (ROM) and read/write-accessible-memoiy (RAM) to perform the controller function.

Inspection and tolerance Inspection variations are often the most critical and most overlooked aspect of the tolerance of a fabricated product. Designers and processors base their development decisions on inspection readings, but they rarely determine the tolerances associated with these readings. The inspection variations may themselves be greater than the tolerances for the characteristics being measured, but without having a study of the inspection method capability this can go unnoticed. 

Other simulation studies reported on the differences between ATR and SR fuel processors for liquid hydrocarbons [82]. The results showed that a fuel processor based on the SR technology gives a higher power than an ATR-based fuel processor. However, this higher performance is counterbalanced by a much higher plant complexity, resulting in increased cost and an impact on system controllability and start-up time.

Commercial processor-based electrochemical instruments are available in two forms. In the first configuration, a general-purpose laboratory or personal computer is interfaced to the analog instrumentation. In the other approach, the package is integrated in such a way that the processor is dedicated to the electrochemical experiments. Several dedicated, processor-based pulse polarographs... 

At this writing it is possible to link digital instrumentation with notebook computers and even achieve portability. Developments have been so rapid in this area that it is difficult to imagine what will come next. General-purpose processor-based electroanalytical instruments are now available from Amel, Bioanalytical Systems, Cypress Systems, EcoChemie, Metrohm, Tacussel, and Princeton Applied Research. 

Hi-Tech Scientific Limited (Salisbury, England) recently introduced a stopped-flow (SF-51) instrument with conductivity detection that uses a five-mixer aging block that gives preparative quench aging times in the range of 1.0 ms to >10 s (Fig. 4.16). Preparative quench and stopped-flow experiments can be performed under total thermostatted, anaerobic, and chemically inert conditions. The entire stopped-flow package consists of the sample handling unit, a spectrophotometer, and a data processor based on the Apple lie. 

In addition, a number of automotive companies are in joint ventures to develop gasoline fuel processors based on POX or CPO technology. These include the following ... 

A fully integrated autothermal fuel processor based on a bi-fimctional ATR catalyst has been designed, fabricated and checked out. The unit continues to show progress towards the FreedomCAR targets and will be tested in the summer of2002. 

Use the fuel processor simulation tool to evaluate the performance of a fuel processor based on the reactor design and establish catalyst performance criteria required for optimum performance of the component reactors and desired performance of the fuel processor. 

Better define the sulfur removal requirements for the fuel processor based on sulfur tolerance studies for the ATR and WGS catalysts. 

Fuel processor-based FCVs are projected to cost about 10% ( l,000- 2,000 per vehicle) more than compressed-hydrogen vehicles - roughly the same as metal hydride-based FCVs.
