the method of entropy production minimization for finding energy efficient paths of operation of process equipment is first presented using an instructive example with optimal control theory. with refer-ence to the earlier investigations, the researchers present some design rules that relate to the designs’ en-tropy production. minimum entropy production is not obtained in special cases, not ge...

Efficient production systems are necessary for the realization of products that fulfil customer needs and delivery requirements. Generally, the task of designing production systems belongs to the Production Engineering field. The system design work is, therefore, often managed and performed by production engineers at manufacturing plants with the support of relevant expertise from other discipl...

در این پایان نامه به آنالیز و طراحی و همچنین شبیه سازی یک میکسر در باند فرکانسی ghz 0.5-6 با استفاده از تکنولوژی tsmc rf cmos 0.18 µmپرداخته شده است. هسته اصلی این میکسر ساختار کسکود می باشد که باعث افزایش بهره و خطسانی و نویز فیگر می شود، اما معمولا داری توان تلفاتی نسبتا بالایی می باشد. در این پایان نامه برای بهبود معضل یاد شده، از تکنیک تزریق بدنه استفاده شده است. استفاده از دژنراسیون مقاومت...

The use of a structured approach to production system design is an effective means to improve a firm’s overall manufacturing capability. Design of a production system in addition to defining system architecture (subsystem organization and integration) also includes allocating high-level system requirements to subsystems. An area where requirements allocation is critical to system performance is...

  In this paper, the system reliability in the design stage and before production is improved. The proposed algorithm is based on the fact that the chosen structure should be practical in reality. First, possible structures for the system of interest are designed then the optimum structure is chosen for production. The proposed approach to select the optimal alternative is to determine the effe...
