Communication-Based Train Control (CBTC) system is an automated train control system to ensure the safe operation of rail vehicles using data communication. Bidirectional wireless train–ground communications is used to transfer control data between trains and wayside equipment. Wireless local area network (WLAN) based CBTC has impact on train control performance while taking handoff decisions. This may leads to communication interrupt and long latency. Inorder to minimize the handoff latency and to improve the performance, a handoff scheme in CBTC system based on WLANs with multiple-input-multiple-output is proposed.
The paper presents the modeling, simulation and analysis of an AC-DC converter based PWM rectifier. It provides a suitable control algorithm for a pulse width modulation rectifier which reduces ripple from the DC output side as well as shapes the input current properly. The basic objective of a PWM rectifier is to regulate the DC output voltage and also ensure a sinusoidal input current and unity power factor operation. This is implemented by high speed IGBT switches connected in anti parallel mode across the rectifier diodes
This paper proposes a coordinated control of rotor side converters (RSCs) and grid side converters (GSCs) of variable speed doubly-fed induction generator (DFIG) based wind generation systems under unbalanced voltage conditions. The control scheme uses stator flux-oriented control for the rotor side converter and grid voltage vector control for the grid side converter. System behaviours and operations of the RSC and GSC under unbalanced voltage are illustrated. The cocoordinated control schemes manage to restore the wind turbines normal operation after the clearance of fault
This review investigates earthworms as reactors towards the development of designer earthworms for the decomposition of complex polymeric structures. Unit operation aspects pertaining to vermicomposting is least addressed or cited in literature, while a lack of models employing worms as composting agents recognizable as biological reactors is quite apparent.

http://www.applicationpersonalstatement.com College application personal statement A personal statement is an important document in any application process, be it for college, residency program or for a job. College admission procedures are tiresome and the application process is competitive the personal statement is a vital part of this process, although school grades and GPA are considered, it is mostly not the only criteria for selection as all students usually have same qualify and difference in grades therefore the college application personal statement is important, as it is the only way you stand out from others.
http://www.graduatepersonalstatement.net Graduate Personal Statement Another common nerve racking experience and process is obtaining admission into a graduate school. Graduate schools are usually very competitive and only the top cream get admission into their programs. Therefore, for one to effectively affect the admission personals and leave a positive impression on them, you will need a graduate personal statement.
The effect of traditional fire on available soil nitrogen and rate of N-mineralization in the oak forest soil of Lambui hill, Ukhrul district, Manipur, North East India have been studied. The rate of ammonification, nitrification and mineralization varied from 0.08 to 5.99 µg g -1 month -1 , 0.40 to 2.52µg g -1 month -1 and 0.46 to 9.09µg g -1 month -1 of soil in the traditional burnt site, 0.31 to 3.93µg g -1 month -1 , 0.14 to 2.52µg g -1 month -1 and 0.48 to 5.67µg g -1 month -1 of soil in the unburnt site and 0.19 to 4.00µg g - 1 month -1 , -0.09 to 2.17µg g -1 month -1 and 0.33 to 5.61µg g - 1 month -1 of soil in the control site respectively for different months throughout the year. The rate of ammonification, nitrification and mineralization were found to be higher in the traditional burnt site followed by unburnt and control forest site which may be due to the increase of decomposable organic matter and increase of soil temperature during the operation of tradi
