To control the spreading of corona virus there is a need to advance exchang- ing innovation for supplanting contactless switch. This project deals with design that has no-touch model works entirely on card gestures. smart switch includes sensor can detect movements and translates them into commands controlling lights, fans, various home appliances. The main idea build feasible device switching,...

Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...

In this paper, we study the performance of high-speed packet switches, where the switch fabric operates at a slightly higher speed than the links, i.e., a speeded-up switch. As link speeds keep increasing, the speedup of N (number of links) needed for pure output queueing (which is the best) becomes a significant technical challenge. This is one of the main reasons for the renewed interest in m...

Interconnection networks are important parts of modern computing systems, facilitating communication between a system’s components. Switches connecting various nodes of an interconnection network serve to move data in the network. The switch’s delay and throughput impact the overall performance of the network and thus the system. Scheduling efficient movement of data through a switch and config...

this paper presents a novel control method to improve the efficiency of low-voltage dc-dc converters at light loads. pulse width modulation (pwm) converters have poor efficiencies at light loads, while pulse frequency modulation (pfm) control is more efficient for the same cases. switching losses constitute a major portion of the total power loss at light loads. to decrease the switching losses...

Cache coherent non-uniform memory access (CC-NUMA) multiprocessors provide a scal-able design for shared memory but they continue to suuer from large remote memory access latencies due to comparatively slow memory technology and data transfer latencies in the in-terconnection network. In this paper, we propose a novel hardware caching technique, called switch cache, to improve the remote memory...

In this article, metal oxide varistor (MOV) design optimization and switching control in the main circuit breaker (MCB) branch of a progressively switched hybrid dc (DCCB) is presented. A DCCB can achieve faster fault isolation with reduced peak current magnitude transient recovery voltage compared regular due to its modified strategy. Consequently, thermal stress on semiconductor devices MCB s...
