Concept-based partitioning for large multidomain multifunctional embedded systems

Abstract: Hardware-software partitioning is an important phase in embedded systems. Decisions made during this phase impact the quality, cost, performance, and the delivery date of the final product. Over the past decade or more, various partitioning approaches have been proposed. A majority operate at a relatively fine granularity and use a low-level executable specification as the starting point. This presents problems if the context is families of industrial products with frequent release of upgraded or new members. Managing complexity using a low-level specification is extremely challenging and impacts developer productivity. Designing using a high-level specification and component-based development, although a better option, imposes component integration and replacement problems during system evolution and new product release. A new approach termed Concept-Based Partitioning is presented that focuses on system evolution, product lines, and large-scale reuse when partitioning. Beginning with information from UML 2.0 sequence diagrams and a concept repository concepts are identified and used as the unit of partitioning within a specification. A methodology for the refinement of interpart communication in the system specification using sequence diagrams is also presented. Change localization during system evolution, composability during large-scale reuse, and provision for configurable feature variations for a product line are facilitated by a Generic Adaptive Layer (GAL) around selected concepts. The methodology was applied on a subsystem of an Unmanned Aerial Vehicle (UAV) using various concepts which improved the composability of concepts while keeping performance and size overhead within the 2p range.

Computational analysis of flow in turbines

Abstract: Computational fluid dynamics (CFD) is a simulation tool, that employs applied mathematics and powerful computer to model fluid flow situations to anticipate the mass, momentum and heat transfer and most favorable design in industrial processes. Turbine is a rotary engine actuated by the impulse or reaction of a current of fluid subject to pressure which is made with a series of curved vanes on a central rotating spindle. CFD at present is the most vital tool to design and analyze different types of turbines. This paper is a review of work carried out in the analysis of flow in different turbines employing CFD software. Literature review of CFD analysis in turbines by various researchers is elucidated. In addition, the merits and demerits of CFD analysis of flow in turbines are mentioned. Future work germane to CFD investigation in turbines is also provided.
