Background: Due to the lack of a proper waste management system, Tehran Municipality Region 20 is facing economic and environmental problems such as the high costs of a disposal system and source pollution. Life cycle assessment (LCA) is a method for collecting and evaluating the inputs, outputs, and potential environmental impacts of a product system throughout its life cycle. The current stud...

Background: Numerous unique characteristics of the nanosized gold, including high atomic number, low toxicity, and high biocompatibility make it one of the most appropriate nanostructures to boost radiotherapy efficacy. Many in-vivo and in-vitro investigations have indicated that gold nanoparticles (AuNPs) can significantly increase tumor injuries in low kilovoltage radiotherapy. While deep-lyi...

In this paper, an intelligent control strategy based on combination of the “flatness based control technique” and the “perturbation and observation (P&O) MPPT algorithm” is developed and investigated to control a hybrid electric energy source (HEPS). This EHPS is composed of a fuel cell system (FC) and a solar panel (SP), as the main source and a supercapacitor bank (SC), as the auxiliary sourc...

The potential-energy surface for has been computed at the HF/6-311G** and MP2/6-311G** levels. The calculated H É 2 results conÐrm that trans-planar HOSO is a transition state but not a stable structure. The decomposition channel for the HOSO adduct has been studied by analysing the transition states and stationary points. The kinetic stimulus for the rearrangement and dissociation of the radic...

امروزه کیفیت توان هم از طرف شبکه و هم از طرف مصرف کنندگان توجه ویژه ای را به خود جلب کرده و این موضوع به خاطر استفاده بسیار گسترده بارهای حساس و تجهیزات الکترونیکی است که ممکن است تحت اختلالاتی نظیر فلیکر ولتاژ، هارمونیک، کمبود و بیشبود ولتاژ و قطعی های موقت قرار بگیرند. این اختلالات موجب عملکرد نامناسب بارهای حساس، گرمای بیش از حد تجهیزات، خرابی موتورهای الکتریکی، اندازه گیری های نادرست و عملک...
