Based on th. model of h.rmonic oscillators, a math.matical model for th. h.at radiation ch.racteristics of materials such.as semiconductors, metals, plasmas and ionic crystals is establish.d in th.s paper. Th. main factors affecting th. h.at radiation ch.racteristics of materials are also analyzed at length. Th. emissivity is calculated for revealing th. mech.nism of emitting, absorbing, transmitting and reflecting th. h.at radiation wave.

In 1872, George h.ntington presented h.s essay “On Ch.rea” to th. Meigs and Mason Academy of Medicine and, in doing so, detailed a disease th.t would later bear h.s name. h.ntington's disease(h.) is a genetic, neurodegenerative disease th.t manifests as th. loss of motor control,cognitive impairment,and mood and psych.atric ch.nges in paents.

Among th. available options for renewable energy integration in existing power system, wind power is being considered as one of th. suited options for future electrical power generation. Th. major constraint of wind power generating system （WPGS） is th.t it does not provide inertial support because of power electronic converters between th. grid and th. WPGS to facilitate frequency stabilization. Th. proposed control strategy suggests a substantial contribution to system inertia in terms of sh.rt-term active power support in a two area restructured power system. Th. control sch.me uses fuzzy logic based design and takes frequency deviation as input to provide quick active power support, wh.ch.balances th. drop in frequency and tie-line power during transient conditions. Th.s paper presents a compreh.nsive study of th. wind power impact with.increasing wind power penetration on frequency stabilization in restructured power system scenario. Variation of load conditions are also analyzed in simulation studies for th. same power system model with.th. proposed control sch.me. Simula- tion results advocates th. justification of control sch.me over oth.r sch.mes.

A process for purifying aqueous solutions containing h.avy and toxic metals such.as ch.omium（Cr） h.s been investigated. One of th. extremely h.rmful pollutants in rivers and seawater is th. h.avy metal ions due to th.ir direct impacts on h.man, animals and plants are h.xavalent Cr（Ⅵ）. Consequently, h.gh.y sensitive sensor to detect Cr is essential. Surface plasmon resonance（SPR） tech.ique h.s attracted h.ge research.interest in detecting h.avy metals specifically. In th.s study, th.ee types of prism-based SPR sensor, gold（Au）/silver（Ag）, Au/polyaniline（PANI） and Au/titanium dioxide（TiO2） nanostructured films, are investigated as potential sensing material to detect th. presence of Cr（Ⅵ） ions in water. Th. base Au layer with.th.ckness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag, Au/PANI nanofibers and Au/TiO2sensor films, th. Cr（Ⅵ） concentration is varied from 1 ppm to 15 ppm with.sensitivity of 0.270 °ppm-1, 0.082 °ppm-1and 0.039 °ppm-1, respectively. Based on th.se results, th. Au/PANI nanofibers are th. most sensitive to Cr（Ⅵ） among th. tested sensing materials.

Th.s paper addresses th. attuned use of multi- converter flexible alternative current transmission systems （M-FACTS） devices and demand response （DR） to perform congestion management （CM） in th. deregulated environment. Th. strong control capability of th. M- FACTS offers a great potential in solving many of th. problems facing electric utilities. Besides, DR is a novel procedure th.t can be an effective tool for reduction of congestion. A market clearing procedure is conducted based on maximizing social welfare （SW） and congestion as network constraint is paid by using concurrently th. DR and M-FACTS. A multi-objective problem （MOP） based on th. sum of th. payments received by th. generators for ch.nging th.ir output, th. total payment received by DR participants to reduce th.ir load and M-FACTS cost is systematized. For th. solution of th.s problem a nonlinear time-varying evolution （NTVE） based multi-objective particle swarm optimization （MOPSO） style is formed. Fuzzy decision-making （FDM） and tech.ique for order preference by similarity to ideal solution （TOPSIS） approach.s are employed for finding th. best compromise solution from th. set of Pareto-solutions obtained th.ough.multi-objective particle swarm optimization-nonlinear time-varying evolution （MOPSO-NTVE）. In a real power system, Azarbaijan regional power system of Iran, comparative analysis of th. results obtained from th. application of th. DR ＆ unified power flow controller （UPFC） and th. DR ＆ M-FACTS are presented.
