| The clock tree of modern synchronous VLSI circuits can consume as much as 50% of their entire power budget. Diierent methods of decreasing clock power dis-sipation have been proposed based on low-voltage swings, double-edge triggered ip-ops, gated clocks, etc. In this paper we propose two types of full-swing low-power CMOS clock drivers. Both are based on a stepped charging and discharging of...

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...

INTRODUCTION Single lead atrial synchronous ventricular pacing (VDD) is increasingly being used in place of conventional dual chamber pacing (DDD) for patients with atrioventricular block and preserved sinus node function. Compared to the latter, VDD pacemakers provide similar haemodynamic benefits derived from atrial synchronous pacing, with the added benefit of an easier implant procedure. ...

in this paper an intelligent method through general regression neural networks (grnn) is presented to estimate the depth of salt domes from gravity data. neural networks are as a good tool for automatic interpretation of geophysical data especially for depth estimation of gravity anomalies. the gravity signal is a nonlinear function of depth and density and the geometrical parameters of the bur...

Oral health is a reflection of systemic health. The various nutritional deficiencies not only affect the but also have an impact on oral prevalence Vitamin D deficiency (VDD) rampant globally. (VD) essential for skeletal growth during childhood and adulthood has great tissues odontogenesis. VDD several implications from to adulthood. VD can negatively influence mother child supplementation brin...

This paper describes a research and development (R&D) effort entitled Depot Operation Modeling Environment (DOME). The project is sponsored by the Armstrong Laboratory, Logistics Research Division (AL/HRG) located at Wright-Patterson AFB, Ohio. The effort is focused on enabling of groupware technology to support the extension of IDEF modeling techniques to accomplish Discrete Event System Speci...

A series of wind tunnel tests have been performed on an aerospike-protected missile dome at a Mach number of 6 to obtain quantitative surface pressure and temperature-rise data, as well as qualitative flow visualization data. These data were used to determine aerospike concept feasibility and will also provide a database to be used for calibration of computational fluid dynamics codes. Data wer...
