Описание:An axisymmetric orthotropic thermal conductivity pin fin equation is derived to study the orthotropic thermal conductivity effects on pin fin heat transfer rate and temperature distribution. Theoretical models, CFD modeling, and experiments are used to characterize the thermal performance of heat sinks, fabricated of PPS composite pin fins, in air natural convection and forced convection modes. This book presents a systematic approach to the characterization, analysis, design, and optimization of orthotropic polymer composite fins used in heat sinks for electronic cooling applications. FEM simulation and water cooled experiments, focusing on the radial temperature variations in single pin fins, are used to validate the analytical model. Morphological characterization and thermal conductivity measurements of thermally conductive Poly-Phenylene Sulphide composites are used to determine the significant directional thermal conductivity in such composites. Simplified solutions, for the orthotropic fin heat transfer rate that are easy to use and can be easily implemented in a heat sink design and optimization scheme, are presented.

Agile Software Development

Purpose: Check quality, correctness, and conformance of the application design. Reviewing: Use cases, actors, domain class diagram, screen flows, screen designs, class tables (if any), and interaction diagrams (if any). Outcome: Factual corrections to the domain model, to the screen details. Suggestions or requirements for improved UI or application design, based on either quality or conformance considerations. With these short paragraphs in place, the methodology can be summarized by role (as the following two examples show). The written form of the methodology, summarized by role, is a checklist for each person that can be fit onto one sheet of paper and pinned up in the person’s workspace. That sheet of paper contains no surprises (after the first reading) but serves to remind team members of what they already know. Here is a slightly abridged example for the programmers: Designer-Programmer Writes Weekly status sheet Source code Unit tests Release notes ... Reads:Actor descriptions UI style guide ... Reviews: Application design review (etc.) Publishes: Application. configuration Test cases (etc.) Declares: UI Stable You can see that this is not a methodology used to stifle creativity ...»

Maintenance Strategies under Consideration of Logistic Processes. Modelling, Simulation and Optimization
However, production system operator' s main intention is to optimize the profitability of the production system and not the availability of the system. The proposed model is aimed overcoming those deficiencies. Main part of the work lies in the extended maintenance and failure module that offers a representation of different maintenance strategies but also incorporates the effect of over-maintaining and failed maintenance (maintenance induced failures). Based on that model, optimizations are performed to maximize availability and profitability of the production system by varying maintenance strategies but also logistics factors. Those optimizations showed that there is a stringent connection between production system availability and logistic decision variables and that financial objective functions are the better optimization criterion than production system availability. Most of them have concentrated on the availability aspect only without incorporating further aspects as logistics and profitability of the overall system. In the last decades, there has been many attempts to create maintenance models for availability optimization.
