The continuously variable transmission (CVT) is a type of transmission that can adopt any arbitrary gear ratio. Whereas typical transmissions utilize toothed gears, the CVT employs a sphere in rolling contact with a set of rollers; loads applied to the CVT are supported across these rolling contacts, resulting in microslips of varying amounts at each contact area. In this paper, we describe the...

Cerebral vein thrombosis (CVT) is uncommon disease and known risk factors of CVT are hereditary thrombophilia, pregnancy, puerperium, and use of oral contraceptives. However, 25% of all cases are considered to be idiopathic. Thyrotoxicosis may be a predisposing factor of CVT due to a hypercoagulable state. Possible associations between thyrotoxicosis and CVT have been described in several case ...

Continuously variable transmission (CVT) is a type of automatic transmission that can change the gear ratio to any arbitrary setting within the limits. The most common type of CVT operates on a pulley system that allows an infinite variability between highest and lowest gears with no discrete steps. However, the current CVT system with hydraulic actuation method suffers from the power loss. It ...

The main purpose of this paper is to explore whether and how the amount of firmsponsored Continuing Vocational Training (CVT) provided in Sweden from 1999 onwards was influenced by institutional conditions. The Swedish labour market is characterised by a relatively large amount of publicly subsidised CVT. How this affects the incidence of firm-sponsored CVT ultimately depends on whether publicl...

Use of automatic transmission systems in motor vehicles in addition to improving the ride comfort is also expected to reduce fuel consumption. The principle of the system Continuously Variable Transmission (CVT) is producing a variation of the ratio of the displacement system (i) as a function of velocity. The main problem is to change the variator CVT push-belt continuously variable from PULLE...

The purpose of this study was to determine the magnitude of vasodilation by CVT-3146 in different vascular beds and to compare it with that by adenosine in conscious dogs. Intravenous bolus injections of CVT-3146 (0.1-2.5 microg/kg) or adenosine (10-250 microg/kg) caused a dose-dependent increase in the coronary blood flow (CBF) and a dose-dependent decrease in the late diastolic coronary resis...

This paper proposes a full-hybrid driveline based on an electric continuously variable transmission (e-CVT), which is inspired by the car industry’s most successful solution. The describes operating principle, system architecture, and control scheme of proposed driveline. An analysis four possible modes shows that e-CVT leads to performance similar conventional tractors, as well unusual feature...

Capacitive Voltage Transformers (CVTs) are common in high-voltage transmission line applications. These same applications require fast, yet secure protection. However, as the requirement for faster protective relays grows, so does the concern over the poor transient response of some CVTs for certain system conditions. Solid-state and microprocessor relays can respond to a CVT transient due to t...

In this paper the theory of Carry Value Transformation (CVT) is designed and developed on a pair of n-bit strings and is used to produce many interesting patterns. One of them is found to be a self-similar fractal whose dimension is same as the dimension of the Sierpinski triangle. Different construction procedures like L-system, Cellular Automata rule, Tilling for this fractal are obtained whi...

BACKGROUND AND PURPOSE Cerebral vein thrombosis (CVT) is a type of venous thromboembolism. Whether the risk of pulmonary embolism (PE) after CVT is similar to the risk after deep venous thrombosis (DVT) is unknown. METHODS We performed a retrospective cohort study using administrative data from all emergency department visits and hospitalizations in California, New York, and Florida from 2005...
