A new method for digital image watermarking which does not require the original image for watermark detection is presented. Assuming that we are using a transform domain spread spectrum watermarking scheme, it is important to add the watermark in select coe cients with signi cant image energy in the transform domain in order to ensure non-erasability of the watermark. Previous methods, which di...

the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...

Statistical energy analysis (SEA) represents a framework for analyzing the high-frequency response of complex structures to mechanical or acoustical excitation [1]. In SEA, a structure is divided into subsystems and the energy #ow between these subsystems is described using coupling loss factors. In case of coupled plate subsystems, coupling loss factors are often expressed in terms of wave tra...

Extreme weather conditions and natural disasters (ND) are the main causes of power outages in electric grid. It is necessary to strengthen electrical system’s resilience during these catastrophic occurrences, microgrids may be seen as best way achieve this goal. In paper, two different energy system scenarios were proposed for increasing resiliency random outages. first scenario, a diesel gener...

Small-scale dairy farming in Bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. Poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. Locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

Kawaluso Island is one of the outermost islands in Indonesia with a distance 68 KM from city Tahuna or 5-10 hours by boat capital Sangihe Islands Regency, Tahuna. Currently, electricity on supplied diesel power plant (PLTD) capacity 200 kW. This condition causes to be electrified 12 per day. So that additional sources are needed so 24 Therefore, solar (PLTS) alternative as for and reduces cost ...

and Energy Functions in Solvable Lattice Models Atsushi Nakayashiki and Yasuhiko Yamada Graduate School of Mathematics, Kyushu University Abstract The relation between the charge of Lascoux-Schuzenberger and the energy function in solvable lattice models is clari ed. As an application, A.N.Kirillov's conjecture on the expression of the branching coe cient of c sln=sln as a limit of Kostka polyn...

Because of the fickle nature renewable sources energy production, professionals in this sector have developed hybrid systems (HRES) that offer a constant and stable load supply. This research intends to build off-grid (HES) Malang, Indonesia, uses solar generator, wind turbine, biogas power public buildings. The HOMER program was used construct model. Following computations, multiple system mod...

Building information modeling can help in predicting the energy efficiency in future based on dynamic patterns obtained by visualization of data. The aim of this study was to investigate the effective parameters of energy consumption using BIM technology which can evaluate the buildings energy performance. First, three forms of general states in the building were modeled to evaluate the propose...
