This paper describes our research work towards the development of an optical guidance system for multiple mobile robots in an indoor environment. The guidance system operates with an environmental model, communicates with mobile robots and indicates their target positions by means of a light projection from a laser pointer onto the ground. Processing the image data from a CCD color camera mount...

Adhering cells actively probe the mechanical properties of their environment and use the resulting information to position and orient themselves. We show that a large body of experimental observations can be consistently explained from one unifying principle, namely that cells strengthen contacts and cytoskeleton in the direction of large effective stiffness. Using linear elasticity theory to m...

Imagine a test that would allow you to predict the type of career for which a person is best suited For example, Mary comes to you for career counseling. She presents you with her education and work history, and an outline of her career objectives. Specifically, she says that she would like to find an entry-level position where she can help people, and is interested in a career in the social se...

"The many generations of psychiatrists, psychologists and psychiatric social workers who passed through their training in child guidance under his directorship, have reason to remember his fatherly kindness and the steadfastness and good humour with which he watched over their professional development. He stood the brunt of the early days of struggle to win recognition for the value of child gu...

Mobile operators currently prefer optimizing their radio networks via re-homing or cutting over the cell sites in 2G or 3G networks. The core network, as the parental part of radio network, is inevitably impacted by the re-homing in radio domain. This paper introduces the cell site re-homing in radio network and analyzes its impact on the performance of GSM/UMTS core network. The possible re-ho...

Short-term travel time prediction is very important to the real time travelers’ information and route guidance system. Various methodologies have been developed for dynamic travel time prediction. However, most of the existing studies presume that path travel time is the simple addition of travel times on the consisting links. Through simulation, it is shown that, under recurrent traffic condit...

Neural cells are well known to be affected by the topographical features of the surfaces to which they adhere. There have been numerous reports showing guided neurite extension on microgrooves and micropillar arrays made of a wide range of materials. However, it has recently been disclosed that neural cells on nanotopographies exhibit much more derivatized and complicated responses than just ne...
