1 I n t r o d u c t i o n With the success of object-orientation in complex application domains, an interest in reverse engineering of legacy relational databases into object-oriented specifications has been risen. Such a specification can be seen as defining a view of the relational database in terms of an object-oriented data model. The derivation of such a view has received considerable at t...

Gesture recognition is an important skill for robots that work closely with humans Gestures help to clar ify spoken commands and are a compact means of re laying geometric information We have developed a real time three dimensional gesture recognition sys tem that resides on board a mobile robot Using a coarse three dimensional model of a human to guide stereo measurements of body parts the sys...

tention in the search for bioactive compounds to develop new drugs. We have taken note of brown algae of the genus Sargassum (Sargassacea, Fucales), which contain structurally unique secondary metabolites such as palstoquinones, chromanol, and chromenes. In the course of studies on search for bioactive molecules of algae, we isolated plastoquinones [hydroquinone (1) and quinone (2)] together wi...

to those involving n bonds as well. It is our con­ tention that the constants determined and used in this investigation are universal to all the hydrocar­ bons, be they aliphatic or aromatic. Furthermore, we believe that the technique as used in the deter­ mination of the atomization energies and stable con­ figurations stands unique in its class of semi-empiri­ cal calculations. Be that as it ...

Research is related to the biology and ecology of white mistletoe (Víscum álbum L.), with an analysis its impact on dendroflora natural artificial ecosystems. The sequence stages invasive cycle mistletoe, starting from stage infection, intensity invasion (the degree spread in crown), suppression host trees, their death biodegradation, as well mechanism these processes. These have different dura...

human resource plays a key role in a society and also for all kind of organization, therefore offering a reasonable and intelligent way for selection of a suitable and essential career. artificial intelligence (ai) is used today in science, engineering, business, manufacturing, management and many other fields. expert systems as a branch of ai have attracted the at-tention of mostly large and...

Under the common theme of physical-layer aware optimization and design in stochasticwireless networks, this dissertation can be broadly organized into the following two parts:In Part I, based on optimal stopping theory, a framework for channel-aware distributedscheduling is developed for exploiting rich diversities at the physical-layer and mediumaccess control (MAC) layer; ...

THE RECENT report of the Interdepar tmental Committee to Coordinate Health and Welfare Activities, which was submitted by the President to the Congress,1 has focused Nation-wide a t tention both on the serious unmet needs for medical service prevailing in this country and on the necessity for developing a national health program. Corroborative evidence of the lack of adequate medical care for n...
