in this paper, we investigated the necessity and effects of optimal control methods in the stability and performance of a micro-grid that operates in islanded mode. the micro-gird is consisted of a combine heat and power (chp), a capacitor bank (cb), photovoltaic panel (pv) as power generation sources. in addition, battery and the building electricity and thermal load are placed on the load sid...

Tendinopathy is a chronic tendon disease which can cause significant pain and functional limitations for individuals, collectively places tremendous burden on society. Resistance training has long been considered the treatment of choice in rehabilitation tendinopathies, with both eccentric heavy slow resistance demonstrating positive clinical effects. The application progressive loads during es...

the studies report the synthesis of novel graft copolymer of oatmeal. polymethyl methacrylate grafting was carried out on oatmeal backbone via ‘microwave assisted’ approach. the graft copolymers were optimized by varying monomer and can concentration. the synthesized graft copolymers were characterized by intrinsic viscosity, ftir, tga, sem, elemental analysis, number average molecular weight a...

the current state of whitefish population and their organisms have been investigated in subarctic lake chuna exposed to long-term air pollution from copper-nickel industry. both annual and long-term heavy metals and acid oxides loads on the lake have been determined. a qualitative assessment has been made for water and bottom sediments. the investigation results have been compared with those of...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

BACKGROUND Our understanding of low back disorder causality is limited in that how biomechanical loading acting on various spinal tissues initiates the pain pathway is not clear. Previous studies suggest that cytokines may be important in mediating the inflammatory responses in patients with back pain. This study quantified the acute biochemical responses to physical work stressing the low back...

In the 1990‟s, during the background works of Eurocode 1991-2 (Traffic loads on bridges), extreme loads and extreme load effects have been evaluated by using WIM data recorded at various European locations. The most used WIM data file is a WIM data record, 2-week long, recorded at Auxerre on a French heavy trafficked motorway in 1986. Today, WIM records are longer and much more accurate, thanks...

Fiber-Wireless (FiWi) networks typically combine an optical access network with a wireless access network so as to build on the respective strengths of the optical and wireless network technologies. Prior analytical throughput-delay studies of FiWi networks have typically considered heavy-loaded traffic models, i.e., constantly backlogged source nodes. In contrast, in this paper we present a mo...

Analysis of heavy metals in top soil samples from Nzoia sugarcane farms in Western Kenya found elevated levels of heavy metals in the soils with mean concentrations (mg kg⁻¹ dry weight) of 142.38, 59.12, 73.35, 116.27, 409.84 (dry season) and 144.22, 50.29, 72.14, 158.81, 368.83 (wet season) for Cr, Pb, Cu, Zn and Fe, respectively, compared with a control soil sample from an adjacent field wher...
