Because of the ubiquity of the WIMP paradigm, many researchers seek to design new pointing facilitation techniques for Fitts-style pointing tasks. However, many of these pointing facilitation techniques make one of two simplifying assumptions: either salient targets are sparsely placed on the display, or there exists some ability to identify the endpoint, the target, of a user's movement in rea...

We report a role for long-distance retrograde neurotrophin signaling in the establishment of synapses in the sympathetic nervous system. Target-derived NGF is both necessary and sufficient for formation of postsynaptic specializations on dendrites of sympathetic neurons. This, in turn, is a prerequisite for formation of presynaptic specializations, but not preganglionic axonal ingrowth from the...

PURPOSE Divergence excess intermittent exotropia is thought to comprise 2 types of deviation, simulated and true. It is believed that simulated divergence excess is akin to a basic deviation but is controlled at near through accommodative and adaptive fusional vergences. While fixation target detail is known to influence accommodation and subsequently deviation size, no previous study has inves...

This is the first study to test the extent to which reflections help locate objects in space and perceive their size. For planar mirrors, the relative size of a target and its reflection is informative about the absolute distance of the target in units of the distance between target and mirror surface. When the target is near the mirror, target and reflection are similar in size; as the target ...

RADAR(Radio Detection and Ranging) is an important system for surveillance reconnaissance by detecting a reflected signal which obtains the range from radar to target, velocity of target. The magnitude varies due cross section characteristic transmission reception antenna, distance between power wavelength transmitted signal. Thus, RCS target determine if can be observed RADAR system. It based ...

In present work, we report synthesis of molybdenum (Mo) thin films by direct current (DC)-magnetron sputtering method. The structural, optical, morphological, and electrical properties were investigated as a function of target-to-substrate distance. From the results, it is evi d ent that with increase in target-to-substrate distance the thickness of films decreases while its sheet resistance an...

Three experiments investigated auditory distance perception under natural listening conditions in a large open field. Targets varied in egocentric distance from 3 to 16 m. By presenting visual targets at these same locations on other trials, we were able to compare visual and auditory distance perception under similar circumstances. In some experimental conditions, observers made verbal reports...

Vulnerabilities and the attacks on Ad Hoc Ondemand Distance Vector (AODV) protocol are investigated and studied via analysis and simulation. The attacks are classified by their target properties. The analysis shows that the ondemand route query enables the malicious host to conduct real time attacks on AODV. False distance vector and false destination sequence attacks are studied by simulation....
