The purpose of this research was to develop new techniques to 1) rapidly sample venous O2 saturation to determine contraction-by-contraction oxygen uptake (V̇o2), and 2) precisely control the rate and pattern of blood flow adjustment from one chosen steady state to another. An indwelling inline oximeter probe connected to an Oximetrix 3 meter was used to sample venous oxygen concentration ([O2]) (via fractional saturation of Hb with O2). Data from the Oximetrix 3 were filtered, deconvolved, and processed by a moving average second by second. Computer software and a program written in-house were used to control blood flow with a peristaltic pump. The isolated canine gastrocnemius muscle complex (GS) in situ was utilized to test these techniques. A step change in metabolic rate was elicited by stimulating GS muscles via their sciatic nerves (supramaximal voltage, 8 V; 50 Hz, 0.2-ms pulse width; train duration 200 ms) at a rate of either 1 contraction/2 s, or 2 contractions/3 s. With arterial [O2] maintained constant, blood flow and calculated venous [O2] were averaged over each contraction cycle and used in the Fick equation to calculate contraction-by-contraction V̇o2. About 5–8 times more data points were obtained with this method compared with traditional manual sampling. Software-controlled pump perfusion enabled the ability to mimic spontaneous blood flow on-kinetics (τ: 14.3 s) as well as dramatically speed (τ: 2.0 s) and slow (τ: 63.3 s) on-kinetics. These new techniques significantly improve on existing methods for mechanistically altering blood flow kinetics as well as accurately measuring muscle oxygen consumption kinetics during transitions between metabolic rates.

The writing of Sustainable Supply chain Management (SSCM) is overflowed with structures. Be that as it may, to date, there has been no endeavor to uncover the irregularities in the current systems and related research patterns. The motivation behind this paper is to survey SSCM structures and feature irregularities. The examination additionally helps in dissecting exploration patterns and builds of SSCM structures and encourages new applications. It utilizes the Scopus database and concludes a couple of systems in the SSCM are considering a period from 2000-2018, utilizing an organized writing audit approach and space specialists. It uses a battery of deliberate necessities-based inquiries to get patterns and covers building squares/develops. It uncovers irregularities at three unique stages: system arrangement, utilization stage catching existing exploration patterns, and build the structure. It likewise offers subtleties at structure square/develops level. Hence, it provides direction in diminishing irregularities and potential changes in existing systems. It uncovered existing growth and sub-builds and aides about the new forthcoming changes in a business affecting SSCM space. It additionally instructs about the qualities and shortcomings of every system. The investigation will help for change/revisions in existing structures by decreasing irregularities and urge new techniques to encourage applications. This is a one-of-a-kind report that offers a structures-based survey, depicts research patterns, and aids about develops a system by uncovering irregularities at each stage. It helps decrease irregularities and provides direction regarding changes in SSCM structure thinking about up and coming difficulties.

Recent developments in Computer Aided Design (CAD) have drastically reduced overall design cycle time and cost. In this paper, wirePATH, a new method for rapid direct tooling, is presented. By using specialized interactive segmentation computer software and wire electrical discharge machining (wire EDM), wirePATH can reduce manufacturing time and cost for injection molds, casting patterns, and dies. Compared to other conventional-mold making methods, wirePATH can reduce fabrication time by as much as 40 to 70%. Wirepath can use a combination of wire EDM and other processes. Our method provides a new means to produce a greater variety in products by changing only portions of the tooling. Segments allow a part of a mold to be replaced to accommodate design changes and repair. WirePATH enables new applications of wire EDM to more complex shapes by bridging the gaps between CAD, our method, wire EDM and conventional manufacturing processes.

Heterogeneous Database Systems

An approach to accommodating semantic heterogeneity in a federation of interoperable, autonomous, heterogeneous databases is presented. A mechanism is described for identifying and resolving semantic heterogeneity while at the same time honoring the autonomy of the database components that participate in the federation. A minimal, common data model is introduced as the basis for describing sharable information, and a three-pronged facility for determining the relationships between information units (objects) is developed. Our approach serves as a basis for the sharing of related concepts through (partial) schema unification without the need for a global view of the data that is stored in the different components. The mechanism presented here can be seen in contrast with more traditional approaches such as “integrated databases” or “distributed databases”. An experimental prototype implementation has been constructed within the framework of the Remote-Exchange experimental system.
