در این پژوهش سعی می‌­شود مدلی برای شبیه‌­سازی چرخه عمر صنعت برق با استفاده از شبیه‌سازی عامل­بنیان ارائه شود، مدل، 5 عامل استخراج شد و شبیه­‌سازی به کمک نرم‌افزار Anylogic صورت پذیرفت. بهینه‌­سازی مدل چهار سناریو نظر خبرگان شد. سناریوی نخست، جذابیت نیروگاه گازی سیکل ترکیبی کاهش یافت بر دو دیگر افزوده نتیجه افزایش تولید آبی است که توجه کمبود منابع کشور به‌صرفه نیست. دوم ورود یک فناوری جدید میزان...

The Design of hexagonal patch is presented withsingle coaxial feed namelysimple hexagonalpatch,hexagonal patch with one triangular slot in ground for circular polarization. The circular polarization of two antennas are obtained with 1.31% axial ratio(AR) for simple hexagonal patch, 4.43% axial ratio hexagonal patch with slotted ground hexagonal patch antenna. The impedance band widths of these ...

Shifts in vegetation composition and cover are the result of processes acting at different levels such as landscapes, hill slopes, or plant interspaces. Analytical approaches designed for discrete objects which are based upon the inherently hierarchical nature of complex systems are well suited to research applications conducted across spatial scales. We quantified spatial and temporal vegetati...

Masalah kulit yang sering banyak dialami dan dikeluhkan oleh orang adalah jerawat atau disebut juga acne vulgaris. Sekitar 80-85% masyarakat di Indonesia mengalami masalah ini. Salah satu penyebab dari vulgaris bakteri Propionibacterium acne. Telah dilakukan penelitian berjudul Formulasi Sediaan Patch Antiacne Kombinasi Ekstrak Etanol Buah Kurma Sukkari (Phoenix dactylifera) Dan Madu Murni (Hon...

This paper provides a comprehensive discussion on patch schedules. This discussion occurs over two parts. The first analyses existing implementations of patch schedules with a focus on Microsoft’s monthly patch schedule. The arguments for patch schedules, namely increased patch quality and better planning within organisations are analysed and the impact of the type of disclosure investigated. I...

Impacts of habitat loss and fragmentation on distribution and population size of many taxa are well established. In contrast, less is known about the role of within-patch habitat quality for the spatial dynamics of species, even though within-patch habitat quality may substantially influence the dynamics of population networks. We studied occurrence patterns of two Orthopteran species in relati...

As a remarkable difference to the existing CAD technology, where shapes are represented by their boundaries, FEM-based isogeometric analysis typically needs a parameterization of the interior of the domain. Due to the strong influence on the accuracy of the analysis, methods for constructing a good parameterization are fundamentally important. The flexibility of single patch representations is ...

acute left atrial thrombosis at the site of the resection of the primary cribriform septum is an exceedingly rare and important complication after atrial septal defect (asd) closure with a pericardial or synthetic patch. this case report presents a mobile thrombus noted on the left atrium at the raw surface site of a resected cribriform primary septum that was not caught in the suture line with...
