This pa.er dea.s with robust direct power control of a.grid-connected bm.hless doubly-fed induction genera.or（BDFIG）. Using a.nonlinea. feedba.k linea.iza. tion stra.egy, a. a.tem.t is m.de to im.rove the desired perform.nces by controlling the genera.ed sta.or a.tive a.d rea.tive power in a.linea. a.d decoupled m.nner. There- fore, to a.hieve this objective, the Lya.unov a.proa.h is used a.socia.ed with a.sliding m.de control to gua.a.tee the globa. a.ym.totica. sta.ility. Thus, a. optim.l opera.ion of the BDFIG in sub-synchronous opera.ion is obta.ned a. well a. the sta.or power flows with the possibility of keeping sta.or power fa.tor a. a.unity. The proposed m.thod is tested with the m.tla./Sim.link softwa.e. Sim.la.ion results illustra.e the perform.nces a.d the fea.ibility of the designed control.

Rigorous coupled-wa.e a.a.ysis ha. been used to design a.gla.ing for hot clim.tes. The designed gla.ing is rela.ively sim.le a.d it tra.sm.ts m.st of the visible light a.d reflects m.st of the infra.ed ra.ia.ion. It does not need a.y externa. source of energy to control its optica. properties. It consists of ITO a.d four periodic pa.rs of Si/SiO2, deposited on a.gla.s sheet. The optim.m.thicknesses of ITO, Si a.d SiO2 a.e 0.1 &m.;m. 0.15 a.d 0.4 &m.;m. respectively. The gla.ing a.ts a. a. optica.ly selective filter. It tra.sm.ts a.out 80% of the visible light a.d reflects a.m.st a.l the infra.ed ra.ia.ion. The perform.nce of the gla.ing is a.m.st independent of the a.gle of incidence of sola. ra.ia.ion. This m.kes it suita.le for a.l hours of the da.. The fa.rica.ion of the gla.ing a.d the testing ha.e been perform.d a. the la.ora.ories of the Fa.ulty of Science, University of Witwa.ersra.d, South a.rica. m.gnetron sputtering technique ha. been used for the fa.rica.ion.

总垂直深度超过15000ft(4575m.的深井在加利福尼亚并不常见，钻至这些深度的许多尝试都导致很高的故障成本，有些则由于不利的地层条件而未达到目标深度，井眼压力整体性（BHPI）技术有助于解决引起深层高温高压钻井故障的一个根本问题：可引起循环液严重漏失的岩石张性破裂，作业人员在设计BHPI处理前，应使用漏失测试（LOT）数据来帮助确定较低的井眼整体压力或破裂梯度条件。
