This paper investigates Sequential Halving as a selection policy in the following four partially observable games: Go Fish, Lost Cities, Phantom Domineering, and Phantom Go. Additionally, H-MCTS is studied, which uses Sequential Halving at the root of the search tree, and UCB elsewhere. Experimental results reveal that H-MCTS performs the best in Go Fish, whereas its performance is on par in Lo...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
in this paper, we have tried to analyze and asses the process of formation and spatial – structural evolution of iranian-islamic cities through tehran case study as well as how to organize and effecting different factors specially modernism on urban elements. also we have discussed about formation and emergence of tehran and the effect of different pre modernism and postmodernism socio-economic...
It is estimated that 3.5 billion people currently live in cities, which equates to more than 50% of the total population (UN, 2010). These cities vary in size from 500,000 to over 10 million inhabitants (termed mega-cities). The number of cities, in particularly mega-cities, are set to significantly increase by 2050. However, this rapid urban population growth is taking place at differing speed...

BACKGROUND Influenza surveillance is an important tool to identify emerging/reemerging strains, and defining seasonality. We describe the distinct patterns of circulating strains of the virus in different areas in India from 2009 to 2013. METHODS Patients in ten cities presenting with influenza like illness in out-patient departments of dispensaries/hospitals and hospitalized patients with se...
Ever since the first French geographical accounts of (intraand peri-) urban agriculture (UA) were published on Central Africa in the 1960s, scattered and isolated UA surveys by individual social scientists (e.g. Egziabher et al. 1994) have gradually been giving way to institutional projects led by multidisciplinary teams. As a result, more and better information is now available on a larger num...
This article aims at identifying the research issues and challenges that need to be addressed to achieve sustainable transportation system for Indian cities. The same is achieved by understanding the current system and trends of urbanization, motorization and modal shares in India; and their impact on mobility and safety (the two basic goals of transportation) as well as environment. Further, t...
