This paper presents a comprehensive survey of fault diagnosis and fault tolerant approaches for permanent magnet synchronous machines(PMSM).PMSMs are prominent in the pervading usage of electric motors,for their high efficiency,great robustness,reliability and low torque *** spite of their extensive appliance,they can be quite non-resilient and inadequate in operation when faults appear in motor drive apparatus such as inverters,stator windings,sensors,*** may lead to insulation failure,torque fluctuations,overcurrent or even system *** that account,fault diagnosis and fault tolerant methods are equipped to enhance the stability and robustness in *** methodologies of PMSM fault diagnosis and tolerance are classified,discussed,reviewed and compared in this paper,beginning with mat hematical modeling of PMSM and then scrutinizing various fault conditions in ***,the scope of research on the topic is *** contribution of this review is to emphasize optimistic schemes and to assist researchers with the latest trends in this field for future directions.

The quickening propensity of growth within the areas of information and communications technology and en-ergy networks has triggered the emergence of a central idea termed as Internet of Energy(IoE).Such a concept relates the internet of things,which is the term used in describing the usage of sophisticated digital control devices with the capability of transmitting data via IT *** concept of an interconnected energy network is being formed in the upcoming days through upgrades in the field of intelligent energy systems to control real-time energy optimization and *** energy industry has had a sustained expansion,reaching the IoE milestone and continuing to this cutting-edge power system,which is the next generation of IoE.A directional pathway from the traditional power system to the IoE has been conducted in this research work by addressing the importance of integrating the smart transmission and communication infrastructure,smart metering,pricing and energy management scheme.A detailed investigation of the IoE with respect to technical angles,such as communication architecture,IoE on the supply&demand side,and IoE protocol based on fundamental elements and essential technologies has been carried out to indicate the blueprint and jurisdiction *** inte-gration,security and energy management challenges may deviate the performance of the IoE technology that has been focused with proper control issues and ***,a directional framework to establish the next-generation IoE system has been constructed with future scopes to insure higher resiliency,cyber-security and stability.

目的评价三维经胸超声心动图（3DTYE）定位诊断二尖瓣脱垂的可靠性。方法接受二尖瓣修补成形术的二尖瓣脱垂患者30例，性别不限，年龄15—64岁，体重43—118kg，ASAII一Ⅳ级“患者术前进行3DTrE检查，术中行多平面二维经食管超声心动图（2DTEE）检查，以术中探查为标准计算3DTrE定位诊断二尖瓣脱垂的敏感度、特异度、准确度，3DTYE与2DTEE的定位诊断结果进行Kappa一致性检验。结果3DTYE图像满意率为93％，2DTEE图像满意率为100％；3DTrE定位诊断二尖瓣脱垂的敏感度88％、特异度95％、准确度93％；3DTIE与2DTEE定位诊断二尖瓣脱垂的结果一致性满意（K=0．88，P〈0．01）。结论3DTTE定位诊断二尖瓣脱垂的敏感度、特异度和准确度较高，临床上可考虑作为2DTEE的替代方法。

Synthesis and Structure of Dimeric Copper (I) Complex from Bis[(2,2’)-dimethyl 2,2’-(1,10-phenanthroline-2,9-diyl) bis(methan-1-yl-1-ylidene)-bis(hydrazinecarbo dithioate)]

Crystal Structure Theory and Applications 2013年第4期2卷 159-166页

作者： Md. Arifuzzaman tasneem A. Siddiquee Mohammad R. Karim Aminul H. Mirza Mohamad A. Ali Department of Chemistry Faculty of Science University of Brunei Darussalam Gadong Malaysia Department of Chemistry Tennessee State University Nashville USA

Metal complex, bis[(2,2’)-dimethyl 2,2’-(1,10-phenanthrline-2,9-diyl)bis(methan-1-yl-1-ylidene)-bis(hydrazinecarrbo dithioate)copper(I)], was synthesized from the reaction of Schiff base, (2,2’)-dimethyl 2,2’-(1,10-phenanthroline-2,9-diyl)bis(methan-1-yl-1-ylidene)-bis(hydrazinecarbo dithioate) and CuCl2 at reflux condition in methanol. The copper centers of the complex appear to be reduced. This probably was facilitated by in situ oxidative formation of disulfide bond at the uncomplexed ligand moieties. Single crystal X-ray diffraction analysis reveals the distorted tetrahedral geometry around the copper centers. This compound crystallizes in the triclinic space group, P-1 with crystallographic parameters: a = 10.006(3) ?, b = 13.272(3) ?, c = 22.123(6) ?, α = 85.656(6)°, β = 81.656(6)°, γ = 73.097(5)°, μ = 1.223 mm-1 , V = 2779.5(13) ?3, z = 2, Dc = 1.437 Mg/m3, T = 293 (2) K.
