The following article analyzes the parallelism between Notes from Underground by Fëdor Dostoevsky and Martin Scorsese’s Taxi Driver. link these works was made explicit director in a documentary movie about his career. revolves, therefore, around underground as place of intimate alienation painful incommunicability. As key to interpretation, I used studies René Girard. In essay he shows p...

Wireless underground sensor networks (WUSNs) consist of buried nodes, which are connected to subsurface underground sensors, and use electromagnetic (EM) waves for underground communications. WUSNs are capable of operating in environments where no other computer network has functioned before, and has the potential to provide real-time, robust, and energy efficient sensing, and communication in ...

Disaster recovery robots must operate in unstructured environments where wheeled or tracked motion may not be feasible or where it may be subject to extreme slip. Many industrial disaster scenarios also preclude reliance on GNSS or other external signals as robots are deployed indoors or underground. Two of the candidates for precise positioning in these scenarios are visual odometry and inerti...

by Jasimuddin U. Ahmed U, Fntil the late 1970s, radon and its daughter products were regarded as radiation health hazards only encountered in the mining and milling of uranium. This notion has dramatically changed as a result of widespread indoor measurements of radon in many parts of the world. Increased radon concentrations in dwellings, for example, have been noted in countries in the temper...

Background: In this study are submitted the radon concentration measurement results of four underground mines: Stanterg, Artana, Hajvali and Badovc, which are owned by Trepça Enterprise, Kosovo. The mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. The radiation exposures caused by radon and radon daughters was determ...

Exploration of planets has significant chances of discoveries e.g. discovery of new substances, as well as finding keys to the origin of our planet. However, some terrains are poorly explored, especially the underground ones. Thus, we have developed underground explorers that use peristaltic crawling of an earthworm for a propulsion part and an earth auger (EA) for an excavation. In this paper,...

a r t i c l e i n f o We provide a theoretical and empirical study of the relation between financial development and the size of the underground economy. In our theoretical framework agents allocate investment between a low-return technology which can be operated with internal funds, and a high-return technology which requires external finance. Firms can reduce the cost of funding by disclosing...

This study investigates the risky positioning behaviour of underground coal mine employees, specifically the behaviour of drivers of remote controlled continuous miners. The patterns of behaviour of these employees are of particular interest, not only because of a series of fatal accidents in New South Wales coal mines with such equipment, but also because of the lack of scientific enquiry of r...
