This paper presents the conveyor, an interconnection device which operates on a 3D skewed memory space and provides the capability of parallel volumetric transformation. The special concept of the conveyor, its design and implementation are discussed.

This study proposes a novel square/triangular wave generator based on a dual outputs differential voltage current conveyor (DO-DVCC). The proposed circuit uses one DO-DVCC combined with three grounded passive components. The presented scheme reveals a compact topology and can produce square/triangular waveform simultaneously. To verify their feasibility, commercially available ICs were used for...

The definition of the current conveyor is presented and it is shown how different generations of current conveyors can all be combined into a single definition of a multiple-output second generation current conveyor (CCII). Next, noise sources are introduced into the model, and a general noise model for the current conveyor is established. This model is used for the analysis of selected example...

OBJECTIVE To determine the prevalence of self-reported attention deficit and hyperactivity disorder (ADHD) symptoms among university students in Eldoret, Kenya. DESIGN A cross-sectional descriptive study of all students who gave consent to participate in the study. SETTING Moi University's Town Campus, comprising the Schools of Medicine, Dentistry and Public Health. SUBJECTS Four hundred ...

Although several studies have shown that asymptomatic human immunodeficiency virus infection elicits an increase in whole body protein turnover, it is not known whether this increased protein turnover includes changes in the kinetics of acute-phase proteins (APPs). To answer this question, we measured 1) the plasma concentrations of four positive (C-reactive protein, alpha1-antitrypsin, haptogl...

Cylindrical microparticle transport and deposition from electrokinetic microflow in a 90 degree bend have been numerically simulated. Under the effect of dielectrohporetic force, gravity and stokes force, it’s found that microparticles with larger size deposit on the lower region of the bend’s outer wall. An exponential curve of deposition efficiency versus the product of stokes number and shap...

Objective. To perform a survey of the American Society of Retina Specialists (ASRS) regarding the use of vitreous cavity fluorinated gas as an adjunct to pars plana vitrectomy for retinal detachment or macular hole repair. Methods. A multiple-choice online questionnaire was administered to members of ASRS. Physician experience, gas preference for vitrectomy, and categorical estimate of observat...

This paper describes the architecture of first and second generation current conveyor (CCI and CCII respectively) and designing an amplifier using second generation current conveyor. The designed amplifier through CCII+ can be used in various analog computation circuits and is superior in performance than the classical opamp. It provides better gain with higher accuracy.

The quest for a useful design tool that incorporated the effect of dynamics of conveyor belts on the design of a conveyor system started halfway the 1950's. It was however not until halfway the 1980's that the first useful design tool became available. In the early days of using dynamics of belt conveyor systems the attention was focused on an analysis of both the starts and the stops of long o...
