A holistic method for selecting tidal stream energy hotspots under technical, economic and functional constraints

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Direct energy functional minimization under orthogonality constraints.

The direct energy functional minimization problem in electronic structure theory, where the single-particle orbitals are optimized under the constraint of orthogonality, is explored. We present an orbital transformation based on an efficient expansion of the inverse factorization of the overlap matrix that keeps orbitals orthonormal. The orbital transformation maps the orthogonality constrained...

Tidal Stream Energy Extraction in Coastal Basins

Tidal Stream Energy Extraction in Coastal Basins A thesis submitted for the degree of Doctor of Philosophy Scott Draper St Catherine's College, Oxford Trinity Term 2011 In recent years the extraction of energy from tidal streams has grown in popularity as a potential source of clean renewable energy. To extract this energy, tidal devices, resembling underwater turbines or hydroplanes, are deplo...

An Efficient Method for Selecting a Reliable Path under Uncertainty Conditions

In a network that has the potential to block some paths, choosing a reliable path, so that its survival probability is high, is an important and practical issue. The importance of this issue is very considerable in critical situations such as natural disasters, floods and earthquakes. In the case of the reliable path, survival or blocking of each arc on a network in critical situations is an un...
