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...

In this paper, the study of thermal CVD grown CNT field emitters in a triode amplifier configuration is reported. The DC characteristics of the CNT triode are investigated, including I/sub a/ vs. V/sub a/ for different V/sub g/. Moreover, DC parameters such as transconductance, amplification factor and anode resistance of the triode amplifier are determined. It was shown that a higher amplification factor can be achieved with optimum gate-anode-cathode spacing such that the cathode is effectively shielded from the anode by the gate but the anode still collects all electrons emitted from the cathode. High emission current at low gate voltage is key to achieving high transconductance. This can be obtained by optimum configuration of high-density CNTs array in a triode structure with a common gate.

In this study, various thicknesses of Pd catalytic films were deposited on Ti/Si substrates and pretreated with NH/sub 3/. The effects of catalyst deposition parameters and NH/sub 3/ pretreatment time (0, 1, and 10 minutes) on the size distribution of Pd catalytic particles, and subsequently, on the diameter and density of synthesized carbon nanotubes (CNTs) were investigated. The CNTs were synthesized by thermal CVD at 750/spl deg/C using methane (CH/sub 4/) as the carbon source, and a mixture of Ar/H/sub 2/ (80 vol.%/20 vol.%) as the carrier gas.

Interviews of twenty-six Industrial Engineering students and graduates were conducted during the first year of a three year study of the unexpected attainment of gender parity in the School of Industrial Engineering at the University of Oklahoma (OU). An analysis of the pattern of participant responses gives insight into industrial engineering (IE) student perceptions of IE. The perceptions were grouped into three broad themes: Career Profile, Discipline Profile, and Discipline Meta-Profile. The Career Profile includes the availability of multiple career paths and flexible careers in this discipline in addition to the potential for the attainment of status through entry into management. People-oriented, broad, and systems-oriented are terms that were used to describe the Discipline Profile. Discipline Meta-Profile is used to describe the participant's perception of other people's perceptions of industrial engineering (i.e. what IE students think other people think). These participants felt that other engineers think of IE as easy, or "imaginary" engineering. The participants also thought that the discipline is invisible, even to other engineers. While the meta-perception of IE might seem to be problematic for the discipline, many of the participants reject the meta-perception. Some participants recognized that IE's focus on people and systems is simply different than other engineering disciplines, not necessarily easier. Other participants felt the potential to enter into management outweighed the discipline meta-perception. One student summarized the response particularly well when he noted that IE is "inviteful" engineering.

We start from a case study of an architecture company and move on to a framework of agents to identify and inform conceptual design. The processes and problems exhibited by the company involved are quite common and can be found in other similar companies. Our intent is to instrument the current process using agent technology, in an effort to improve global awareness during the conceptual design phase, allowing the designers to design so as to facilitate later steps and optimize the process as a whole.
