Continued from last month, a single series diode rectifier is excited by sinusoidal voltage source through inductor. To adjust the diode’s on-duty cycle, we now employ variable resistor for dc load, as shown in Figure 1 . Can predict specific resistance <italic xmlns:...

The emerging of wireless computing motivates radical changes of how information is derived. Our paper concerns with developing push and pull based application in wireless environment. We use a simplified e-health (hospital) context to demonstrate some effective uses of pull-based and push-based mechanisms. The pull mechanism involves information retrieval from a database, and update information...

The effect of a sacrificial layer residue on a cantilever beam in the nano-electro-mechanical nonvolatile memory is investigated for the optimization of reliability characteristics. Different from previous research, pull in voltage model of nano-electro-mechanical nonvolatile memory used triangular residue layer which is considered by real wet etching process. Modified pull in voltage model was...

We previously designed a push-pull perceptual training protocol that effectively reduces sensory eye dominance (SED) and enhances binocular depth detection in human adults (Xu, He, & Ooi, 2010a). During the training, an attention cue precedes a pair of binocular competitive stimulus to induce dominance of the weak eye and suppression of the strong eye. To verify that the success of the protocol...

The physiological demands of weight-pulling dogs have yet to be investigated. Two groups of competitive weight-pulling dogs both underwent two identical pull series 3 h apart. The control group (n 8) was compared with a group fed a rapidly digestible carbohydrate and protein supplement after the first pull series (n 9). Blood was drawn before and after each pull series as well as at 15 and 30 m...

The purpose of the study was to compare the linear kinematics of the barbell and the angular kinematics of the lower limb during the snatch lifts of two different barbell weights in elite male adolescent weightlifters. In the national team level, nine elite male adolescent weightlifters participated in the study. The snatch lifts were recorded by two video cameras under competitive conditions i...

We define the pull-back of a smooth principal fibre bundle, and show that it has a natural principal fibre bundle structure. Next, we analyse the relationship between pull-backs by homotopy equivalent maps. The main result of this article is to show that for a principal fibre bundle over paracompact manifolds, there is a principal fibre bundle isomorphism between pull-backs obtained from homoto...
