Integration with Execution Components

Execution components or supply chain information systems are used for data processing during day-to-day supply chain operations. They have multiple resprai-sibilities in relation to supply chain cOTifiguratiOTi

The radar-sensor and subsequent components are implemented as SOA services in Java. For the demonstration, each service executed on its own computer system. To facilitate integration with the cyber sensor and actuator, the Radar-Sensor Service ran within VMware Workstation (the host operating system was Linux Centos 5, while the guest operating system alternated between Linux Centos 5 and FreeBSD). The other services executed on non-virtualized Linux Red Hat hosts, though in principle they could just as easily have been virtualized. 

In addition to testing the system components, a test of software functionality would be performed to test the system software operation and electronic records and electronic signatures (ERES) compliance (security, data integrity, data backup, and archive). In order to test the software functionality, a predetermined set of instructions can be entered step by step into the system. The system responses are then compared to the expected outcomes of the instruction and any problems with the execution are determined. Some vendors will provide a standard set of data which can be processed by the system to verify the data-handling capability of the system. 

Molecular devices have been defined as structurally organized and functionally integrated chemical systems they are based on specific components arranged in a suitable manner, and may be built into supramolecular architectures [1.7,1.9]. The function performed by a device results from the integration of the elementary operations executed by the components. One may speak of photonic, electronic or ionic devices depending on whether the components are respectively photoactive electroactive or ionoactive, i.e., whether they operate with (accept or donate) photons, electrons, or ions. This defines fields of molecular and supramolecular photonics, electronics and ionics. 

Doped semiconductors are essential components in the modern solid-state electronic devices found in radios, television sets, pocket calculators, and computers. Devices such as transistors, which control electrical signals in these products, are made from M-type and p-type semiconductors. In modern integrated circuits, an amazing number of extremely small devices can be packed into a small space, thus decreasing the size and increasing the speed of electrical equipment. For example, computer microprocessors now contain up to 42 million transistors on a silicon chip with a surface area of about 2 cm2 and are able to execute as many as 1.5 billion instructions per second. 

Roughly speaking, an informatics component can be divided into the application layer (the software end users interact with) and everything beneath it (standard software and hardware that enables the application software to be executed). The integration discussed in the previous subsections is at the application layer, and therefore something that immediately matters to the radiologist... 

Proof testing is executed periodically, and can be implemented using several strategies. The strategy establishes how the tests of the redundant components are scheduled with respect to one another. lEC 61508 (1998-2005) defines proof test as a periodic test performed to detect failures in a safety-related systems so that the system can be restored to an as new" condition or as close as practical to this condition". This standard establishes the need of routine maintenance action in order to detect unrevealed failures, being proof test one of these activities. It thus has an important role in the achievement of safety integrity. 

Another test technique which is common in technical environments is the Boundary Value Analysis (BCS 2001). This technique is well known for user interface tests, but it is even more suitable for testing of the interface of software components. These tests can be executed before the component integration phase. With this technique the boundaries of an interface are tested, both the valid boun-... 

Simply automating human-executed steps or applying conventional automation and instrumentation engineering to laboratory procedures are not in accord with the Lab-on-a-Chip philosophy. Rather, to realize the vision of major scale-down, comprehensive integration and massive parallelization of laboratory tasks, new paradigms and architectures must be developed to shrink and adapt sequences of laboratory processes to the components and methods of microfluidics. The newly integrated Lab-on-a-Chip tools often must provide better limits of detection or enhanced resolution at lower cost than the laboratory systems they replace in order to be adopted by practitioners of traditional laboratory methods.
