Several techniques exist for computing vertical motions. In this paper, radiosonde wind observations are used to compute vertical motions by the kinematic method. The presence of cumulative bias errors necessitates adjustment techniques. Simple tests of two techniques indicate that, for the period of this study, a divergence adjustment that is a function of pressure yields the best adjusted ver...

One of the major goals of robotics research is the construction of humanoid robots that enter human-centred environments. To promote man-machine interaction in daily life robots should have a roughly humanoid shape and use human-like movements. It is therefore crucial to understand how humans coordinate their upper-body movements during daily motor tasks. One of the key assumptions in motor con...

Handling of objects with irregular shapes and that of flexible/soft objects by ordinary robot grippers is difficult. Multi fingered gripper may be a solution to such handling tasks. However, dexterous grippers will be the appropriate solution to such problems. Although it is possible to develop robotic hands which can be very closely mapped to human hands, it is sometimes not to be done due to ...

We have developed an interactive computer-aided design program that supports the mechanical design of devices fabricated in surface micro-machining processes. The program automates kinematic analysis via a novel configuration space computation code, performs real-time simulation and kinematic tolerance analysis, and supports kinematic synthesis. Designers can visualize system function under a r...

An important problem for mechanism design and analysis is reasoning about the relationship between object shapes and their kinematic function. Such reasoning is difficult because of the unstructured influence of the shapes’ metric dimensions. In this paper, we show how a qualitative kinematic analysis can be based solely on symbolic reasoning and evaluation of predicates on metric dimensions. T...

in recent years, biodiesel has been considered as a good alternative of diesel fuels. density and viscosity are two important properties of these fuels. in this study, density and kinematic viscosity of biodiesel-diesel blends were estimated by using artificial neural network (ann). a three-layer feed forward neural network with levenberg-marquard (lm) algorithm was used for learning empirical ...

Force (kinetic) and opto-electrical motion tracking (kinematic) measuring techniques are well established to analyse gait and other movement patterns. During the last years, videofluoroscopy became a new and well accepted technique to get accurate kinematic information of artificial joints in vivo by a three dimensional numerical reconstruction of the single plane projection view of fluoroscopi...
