A Context Sensitive Multilevel Thresholding Using Swarm Based Algorithms

In this paper, a comprehensive energy function is used to formulate the three most popular objective functions:Kapur's, Otsu and Tsalli's functions for performing effective multilevel color image thresholding. These new energy based objective criterions are further combined with the proficient search capability of swarm based algorithms to improve the efficiency and robustness. The proposed multilevel thresholding approach accurately determines the optimal threshold values by using generated energy curve, and acutely distinguishes different objects within the multi-channel complex images. The performance evaluation indices and experiments on different test images illustrate that Kapur's entropy aided with differential evolution and bacterial foraging optimization algorithm generates the most accurate and visually pleasing segmented images.

PSO Based Controlled Six-phase Grid Connected Induction Generator for Wind Energy Generation

This paper deals a detailed performance investigation of asymmetrical six-phase grid connected induction generator(GCIG)in two proposed configurations in variable speed operation.During the system development,regulation of DC-link voltage has been proposed using particle swarm optimization(PSO)based PI controller,ensuring the power flow to utility grid through back to back converters.The closed loop operation of asymmetrical six-phase GCIG using indirect field oriented control in different configurations has been carried out in Matlab/Simulink environment.Analytical results have been verified using real time test results on virtual platform of Typhoon HIL supported with some experimental validation.

Epidemiology of patients admitted to a major trauma centre in northern India

在印度的 ObjectiveTrauma 是一个逐渐地重要的问题，特别地考虑到快速的开发和增加的动力化。社会变化在损伤的传染病学正在导致改变。学习的目的是估计在同意到一个主要损伤中心进入随机的分类选择的 748 个病人的北 India.MethodsAn 观察学习的病人影响损害的原因的各种各样的流行病学的参数在 1 年(到 2009 年 7 月的 2008 年 8 月) 的一个时期上被执行。年龄，性别，损害类型和模式被注意。上面、更低的手足的损害模式也是 noted.ResultsInjuries 在 15-30 年的年龄组主要发生。男性们与男性一起招致了更多的损害到 6:1 的女比率。最脆弱的组是摩托车用户。在之中伤害，农民们是通常包含的大多数。钝损害(94.92%) 比渗透损害是更普通的。在有头损害的病人之中，二 wheelers 联系了事故最普通(40.3%) 。最针的绳索损害从高度(51.09%) 到下降被引起。大多数更低的手足破裂是简单类型。更低的手足的复合破裂比交通规则的上面的手足 fractures.ConclusionStrict 实施更普通，与改进基础结构和行为变化结合了能减少在印度和另外的发展中的国家的道路交通事故的负担。这研究能在作为需要被称为死亡和病态的一个可防止的原因的一个公共健康问题提起道路交通事故的侧面帮助，并且为这主要挑战计划适当干预。预防策略应该根据这些流行病学的趋势被做。
