We report on experimental observation of electromagnetically induced transparency and slow-light (vg c/607) in atomic sodium vapor, as a potential medium for a recently proposed experiment on slow-light enhanced relative rotation sensing [Shahriar, et al. Phys. Rev. Lett. (submitted for publication), http://arxiv.org/abs/quant-ph/0505192.]. We have performed an interferometric measurement of th...

Energy plays a key factor in the advancement of humanity. As energy demands are mostly met by fossil fuels, the world-wide consciousness grows about their negative impact on the environment. Therefore, it becomes necessary to design sustainable energy systems by introducing renewable energies. Because of the intermittent availability of different renewable resources, the designing of a sustaina...

Health challenges present arguably the most significant barrier to sustainable global development. The introduction of ICT in healthcare, especially the application of mobile communications, has created the potential to transform healthcare delivery by making it more accessible, affordable and effective across the developing world. However, current research into the assessment of mHealth from t...

cryptosporidiosis is a widespread cause of diarreheal diseases of humans, young calves, and many mammals caused by infection of intestinal epithelial cells with the protozoal agent cryptosporidium. this study that was conducted in shahriar county of tehran in 2006, altogether 573 stools of calves and 867 stools from diarreheal humans refer to hospitals of county were collected and concentrated ...

3D city building models can improve many applications such as urban planning, navigation, disaster management, traffic control etc., in various aspects especially in visualisation. However, compared with the data volume and complexity of 3D city models, the capability of devices and network band are still limited. To improve the visualisation efficiency, generalisation of 3D city models is requ...

Hidden-city ticket is an interesting airline ticket pricing phenomenon. It occurs when an itinerary connecting at an intermediate city is less expensive than a ticket from the origin to the intermediate city. In such a case, passengers traveling to the intermediate city have an incentive to pretend to be traveling to the final destination, deplane at the connection point and forgo the unused po...

Intelligent environments and cities have become a popular topic in recent literature. The island nation of Singapore has often been mentioned as an example of an intelligent city for its visionary IT2000 project where Information Technology permeates every aspect of the society; at home, work and play (1). The European project IntelCities was aimed at providing citizens more services and increa...

The so-called smart factory is a novel paradigm that is rapidly gaining ground in scenarios for factories of the future. Many manufacturing companies try to raise the level of smartness by considering a number of aspects related to the smart factory. However, there is a lack of field-oriented systematic research to help them fit the interest of industry for promoting interest and diffusion of s...

These days, unless something has the epithet “smart” attached to it, it is nothing. Smart Energy solutions promise cleaner, cheaper and more reliable energy. Smart Cities promise better quality of life for its citizens. We will argue that for a “system” to be SMART, it should Sense Meaningfully, Analyze and Respond Timely. Using real-world examples from the domains of Smart Energy and Smart Cit...

So-called “Smart Dust” is envisioned to combine sensing, computing, and wireless communication capabilities in an autonomous, dust-grain-sized device. Dense networks of Smart Dust should then be able to unobtrusively monitor real-world processes with unprecedented quality and scale. In this paper, we present and evaluate a prototype implementation of a system for tracking the location of real-w...
