A high-speed non-destructive CMOS image sensor with bi-directional multiple charge transfer active pixel scheme is presented. The high-speed intermediate pictures are used in the motion vector estimation with adaptive iterative search. The sensor has an ability to cancel FPN of intermediate image. The proposed adaptive iterative search with high-speed non-destructive intermediate pictures reduc...

This paper explores the system-level power-performance tradeoffs of dynamically varying CPU speed. Previous work in CPU speed-setting considered only the power of the CPU and only CPUs that vary supply voltage with frequency. This work takes a broader approach, considering total system power, battery capacity, and main memory bandwidth. The results, which are up to a factor of four less than id...

People frequently analyze the actions of other people for the purpose of action coordination. To understand whether such self-relative action perception differs from other-relative action perception, the authors had observers either compare their own walking speed with that of a point-light walker or compare the walking speeds of 2 point-light walkers. In Experiment 1, observers walked, bicycle...

This study investigated the temporal characteristics of gait initiation and gait termination. Ten nondisabled adult volunteers and ten people with unilateral transtibial limb loss performed starting and stopping for slow, normal, and fast walking speeds. We used kinematic and anthropomorphic data to determine the body center of mass (BCOM) position of each subject. The BCOM acceleration was der...

A substantial body of evidence points to a cue-based direct-access retrieval mechanism as a crucial component of skilled adult reading. We report two experiments aimed at examining whether poor readers are able to make use of the same retrieval mechanism. This is significant in light of findings that poor readers have difficulty retrieving linguistic information (e.g., Perfetti, 1985). Our expe...

This study recorded basic gait data from 656 healthy primary school-aged children (5-13 years) and 81 young adults (18-27 years) whilst walking over-ground across a level walkway at varying speed. It investigated the effect of gait speed and re-examined the issue of gait maturation. Participants completed 6-8 walks at self-selected slow, free and fast speed along a GAITRite walkway whilst weari...

This work analyzes the causes of slip phenomenon in impeller on basis internal flow mechanism. Detailed optical measurements inside rotation passages a five-bladed centrifugal pump are obtained through particle image velocimetry (PIV). On experimental data, deviation coefficient velocity is proposed and then revised according to factor calculation formula Stechkin. Results show that, at same sp...

The problem of predicting a ship’s form factor and associated scale effects has been subject to many investigations in recent years. In this study, an attempt is made investigate whether the influenced by change speed numerically modelling geosim series KCS hull means RANS solver. turbulence dependence also studied altering closure model among three widely used approaches (the k-?, k-? SST, k-?...

while sophisticated analytical methods like morgenstern-price or finite elementmethods are available for more realistic analysis of stability of slopes, assessment of the exactvalues of soil parameters is practically impossible. uncertainty in the soil parameters arisesfrom two different sources: scatter in data and systematic error inherent in the estimate of soilproperties. hence, stability o...
