Computer systems, future developments

Shared decision making between doctors and patients is an issue i iere computer systems may develop an inqiOTtant lole. Cost effective and am opriate care of chronically wounded patients is an outcome that must be attained in the near future as the number of people affected by chronic wounds burgeons in the next 20 years. Algorithms, decision trees, critical pathways, and computer software that include these processes may make this goal possible. 

The relevance of photonics technology is best measured by its omnipresence. Semiconductor lasers, for example, are found in compact disk players, CD-ROM drives, and bar code scaimers, as well as in data communication systems such as telephone systems. Compound semiconductor-based LEDs utilized in multicolor displays, automobile indicators, and most recendy in traffic lights represent an even bigger market, with approximately 1 biUion in aimual sales. The trend to faster and smaller systems with lower power requirements and lower loss has led toward the development of optical communication and computing systems and thus rapid technological advancement in photonics systems is expected for the future. In this section, compound semiconductor photonics technology is reviewed with a focus on three primary photonic devices LEDs, laser diodes, and detectors. Overviews of other important compound semiconductor-based photonic devices can be found in References 75—78. 

The case study described here concerns a human factors audit of a computer controlled process system which was being introduced in a distillation imit of a chemical plant. The unit was in transition from replacing its pneumatic panel instrumentation with the new system. However, control had not yet been transferred and the staff were still using the panel instrumentation. The role of the project was to evaluate a preliminary design of the computer-based display system and provide recommendations for future development. 

Four serial (RS232) ports are provided for flexible communications to other instruments, i.e. autosamplers. In addition, five analogue inputs, tvsro analogue outputs and 3 TTL input/outputs are provided to ensure complete flexibility. These allow auxihary instruments under direct control and the abihty to process data generated by these in real time. These features extend the range of facihties on these expensive but worthwhile analytical techniques. There is no doubt that future developments in computing will continue to have a radical impact on these instrumental systems. 

Computer system decommissioning can also encompass disconnection, disassembly, and storage (or mothballing) for future use. Accurate specification, design, development, qualification testing, and operational documentation is essential to enable controlled redeployment of the system in a GMP environment. 

Chapter 8—Molecular Interactions Learning from Protein Complexes The spectrum of interactions is critical to comprehending the dynamics of a living system, and understanding it can help to develop methodology for future studies in other systems. Rojas, de Juan, and Valencia review the current state of experimental and computational methods for the study of protein interactions, including prospects for future developments.
