This paper focuses on implementation issues of a virtual environment to support the interaction with a coordinate measuring machine (CMM), which is used to measure dimensions and form of mechanical parts. First, it gives an overview of the implementation, presenting the software "Avalon" and the basic architecture of the developed application. Then, it describes the execution environment, including the description of equipments and devices, characteristics and constraints, and system execution. Finally, it presents the conclusions of the work.

Information technology is providing manufacturers with additional flexibility with regard to their supply chain network choices. Our research studies supply chain network organization structures categorized by the organic and mechanistic management control structures. The structural impacts on cost and fill rate performance are studied in two-echelon and two-supply-chain network organization models under different market coordination conditions using system dynamic simulations. Our results show significant effects of demand and network structural factors, and their interactions, on these measures. As demand becomes dynamic, the cooperative interaction model, where supply chains cooperate to satisfy customer demand, is found to have better system performance than the competitive supply chain model. The analysis also suggests that increasing the responsiveness at the downstream plant is particularly important to the overall system performance improvement.

The purpose of this study was to identify hand factors that change over a five-year period that may be risk factors for the development of functional disability in persons with systemic sclerosis (scleroderma). Sixty individuals with scleroderma were administered assessments of grip and pinch strength, joint range of motion, and pain, and were observed for the presence of digital ulcers, digital scars, calcium deposits, puffy fingers, and tendon friction rubs. Matched-pairs chi square analyses and Fisher's exact tests were performed to compare variables at year 1 and five years later. Grip and pinch strength increased as did joint motion except for the wrist and thumb carpometacarpal joint. There were also significant increases in the presence of scars, friction rubs, calcium deposits, and puffy fingers. Regression analysis was done to determine which variables predicted functional ability. Only puffy fingers predicted functional disability. In conclusion, hand impairment persisted over time while functional ability decreased.

Nowadays fuzzy logic is one of the most perspective directions of the modern theory of control. Fuzzy logic enables us to build knowledge bases and expert models of new generation, capable to store and treat the inaccurate information in modern control systems of productions and transport systems. Other area of application of fuzzy logic is the electronic systems of different assigning. The paper has review-methodical character and contains both introduction in a problem, and new materials.
We first give a definition of simple sets of 1's in 4D binary images that is consistent with (8,80)-adjacency-i.e., the use of 8adjacency to define connectedness of sets of 1's and 80-adjacency to define conne...
