abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
The sensible heat budget of a large-scale area containing an idealized tropical cloud cluster is analyzed. The cluster is assumed to have spatial dimensions and precipitation rates typical of observed cloud clusters. In its early stages of development the idealized cluster consists of isolated deep precipitating convective cells, or "hot towers." A simple model using the assumed precipitation r...
Giant planets embedded in circumstellar discs are expected to open gaps in these discs. We examine the vertical structure of the gap edges. We find that the planet excites spiral arms with significant (Mach number of a half) vertical motion of the gas, and discuss the implications of these motions. In particular, the spiral arms will induce strong vertical stirring of the dust, making the edge ...
Two independent wind profiles were measured every hour during Februa j 1986 with a five-beam, UHF (405 MHz) wind Profiler at Platteville, Colorado. Our analysis of the horizontal wind components over all heights for the entire month gave a standard deviation of about 1.3 m s-' for the measurement errors one can expect for three-beam Profilers in clear air. This study demonstrated that it is imp...
The main objective of this article is to optimize the walking pattern of a 2D humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. To this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. Then, using these trajectories and the inverse kinematics, the position tra...
A method is presented by which combined S-band polarimetric weather radar and UHF wind profiler observations of precipitation can be used to extract the properties of liquid phase hydrometeors and the vertical velocity of the air through which they are falling. Doppler spectra, which contain the air motion and/or fall speed of hydrometeors, are estimated using the vertically pointing wind profi...
We describe simple one-dimensional models of passive (no energy input, no control), generally dissipative, vertical hopping and oneball juggling. The central observation is that internal passive system motions can conspire to eliminate collisions in these systems. For hopping, two point masses are connected by a spring and the lower mass has inelastic collisions with the ground. For juggling, a...
