A comprehensive and accurate wind power forecast assists in reducing the operational risk of generation, improves safety stability system, maintains balance generation. Herein, a hybrid probabilistic density forecasting approach based on transformer network combined with expectile regression kernel estimation (Transformer-ER-KDE) is methodically established. The prediction results various level...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...

Urban expansion has become a widespread trend in developing countries. Road networks are an extremely important factor driving the expansion of urban land and require further study. To investigate the relationship between road networks and urban expansion, we selected Beijing, New York, London, and Chicago as study areas. First, we obtained urban land use vector data through image interpretatio...

     Production and characterization of soft cross-linked gelatin sponge by using glutaraldehyde for blood hemostasis application, is the goal of this study. Biodegradable hydrogels were prepared through crosslinking of gelatin with glutaraldehyde followed by freeze drying. The effects of gelatin concentration, amount of crosslink agent and freeze drying temperature on mechanical properties and...

during this survey 29 sites have been recognized totally. settlement patterns determined base of environmental characteristics such as altitude, ground slope, source of water, petrology and geology, vegetations, land use and specifications of sites including width, chronology, regional distribution and density and all of them have been divided by using geographic information systems (gis) and c...

The synergistic interaction between teammates in association football has properties that can be captured by Social Network Analysis (SNA). The analysis of networks formed by team players passing a ball in a match shows that team success is correlated with high network density and clustering coefficient, as well as with reduced network centralization. However, oversimplification needs to be avo...

To my parents and my brother iii ACKNOWLEDGEMENTS I thank my advisor, Professor Steven W. McLaughlin for his guidance and constant encouragement that got me through every step in my PhD. He was very understanding and always rescued me whenever I got myself into trouble. It has been a pleasure and a privilege to work with him for the past five years. I would also like to take this opportunity to...

Bandwidth estimation in wireless networks is difficult due to the intrinsic randomness of the wireless links. In this paper, we propose a network calculus based method for statistical bandwidth estimation in wireless networks with random service, where the bandwidth is expressed in terms of a statistical service curve with a violation probability. By injecting probing packet trains, the statist...

Lin proposed earlier based on qualitative considerations that electronic motion was associated with negative absolute temperature. Here, a local temperature formula is proposed for electronic motion in atoms and molecules, which allows the existence of negative absolute temperature in a local sense in thermodynamic equilibrium. The proposed temperature formula is a function of total energy dens...

The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
