the history of mankind is intertwined with war. what distinguishes man from other creatures is his ability to dominate and capture the nature; he accomplishes this though using his rationale and making tools which set the ground for production and accumulation of capital. to protect his benefits and accomplish his desire for dominance, man creates weapons which become more developed parallel to...

The objective of this paper is to accurately measure the vibration response tools and hands by simulating hand-held power tools, which are operated astronauts wearing extravehicular spacesuit gloves under microgravity conditions. total value daily exposure subject’s hand obtained. results show that opisthenar more sensitive frequency less than 200 Hz. After weighting, in composite state an unpr...

This paper describes the development of a tendon-driven, multi-fingered dexterous robot hand for space operations. This hand can achieve cylindrical grasps while producing a holding strength necessary for grasping several crew aids, tools (CATs) and interfaces. The design is based on grasping requirements for 242 CATs and interfaces found in the extravehicular activity (EVA) Tools and Equipment...

Chemical classification and labelling systems may be roughly similar from one country to another but there are significant differences too. In order to harmonize various chemical classification systems and ultimately provide consistent chemical hazard communication tools worldwide, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was endorsed by the United Natio...

Meanings of morphological categories are an indispensable component of representation of sentence semantics. In the Prague Dependency Treebank 2.0, sentence semantics is represented as a dependency tree consisting of labeled nodes and edges. Meanings of morphological categories are captured as attributes of tree nodes; these attributes are called grammatemes. The present paper focuses on morpho...

As a broader array of communication tools is developed, designers of learning environments need a better understanding of what kinds of communication each medium is best suited for. Each of the new media have different affordances and constraints. One of our principles for the design of learning environments is “Render unto each medium what it does best.” This paper is an attempt to state some ...
