The conventional structural layout optimization method is usually used to solve the problem of a single structure, but it difficult apply modular aircraft structure containing multiple substructures. Therefore, this paper proposes mean value-based parallel collaborative (MVPM) for layout. This two-stage based on decomposition. basic idea MVPM decomposing into system coordination and several ind...

طراحی سیستمی نخستین گام در روند شکل گیری و تحقق یک سیستم هوافضایی می باشد. در این مرحله تمام مشخصات کمی و کیفی محصول تعیین و تا حد بالایی پیش بینی می گردد. هزینه های مربوط به مسئله ی طراحی خود بخش مهمی از هزینه هایی است که در روند شکل گیری یک سیستم صرف می-گردد. از سوی دیگر در مرحله ی طراحی هزینه های مراحل بعد در روند توسعه ی محصول از جمله ساخت، بکارگیری، و بازنشستگی آن تا حد بسیار بالایی تعیین ...

This article describes information-based approaches to processing and organizing spatially distributed, multi-modal sensor data in a sensor network. Energy constrained networked sensing systems must rely on collaborative signal and information processing (CSIP) to dynamically allocate resources, maintain multiple sensing foci, and attend to new stimuli of interest, all based on task requirement...

The recent development in vehicle-to-everything (V2X) communication opens a new opportunity to improve the positioning performance of road users. We explore benefit connecting raw data global navigation satellite system (GNSS) from agents. In urban areas, GNSS is highly degraded due signal blockage and reflection. 3D building model can play major role mitigating multipath non-line-of-sight (NLO...

We propose a new hybrid recommendation algorithm to optimization the cold-start problem with Collaborative Filtering (CF). And we use neighborhood-based collaborative filtering algorithm has obtained great favor due to simplicity, justifiability, and stability. However, when faced with large-scale, sparse, or noise affected data, nearest-neighbor collaborative filtering performs not so well, as...
