The quality of tests, in terms of fault coverage and test length, is strongly dependent on the used fault models. This paper presents realistic fault models for multiport memories with p ports, based on defect injection and SPICE simulation. The results show that the fault models for -port memories consist of p classes: single-port faults, two-port faults,..., -port faults. In addition, the pap...

Multiport ring cavities represent the natural generalization of two-port Fabry-Perot interferometers [1] to several modes of the radiation field. They find application in advanced interferometry, division multiplexing and optical cross connect. Recently, a three-port fiber ring laser was suggested and demonstrated to improve sensing resolution [2], whereas multiport optical circulators have bee...

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...

This paper proposes a multiport DC-DC converter for EV fast-charging stations. The proposed is comprised of Ring-Connected Dual Active Bridge (RCDAB) converters, where the connection point between every two adjacent DABs provides DC port. Bypass switches are added to each DAB eliminate unnecessary power processing stages in event idle ports (no EVs) (open circuit ports). nature ring RCDAB theor...

BACKGROUND AND OBJECTIVES Postoperative adhesions occur less often in laparoscopies than in laparotomies, but the incidence can be reduced further. Seprafilm, a sodium hyaluronate/carboxymethylcellulose absorbable barrier, was developed to prevent adhesions after abdominal surgery, and is approved for postoperative adhesion prevention. However, Seprafilm is seldom used in laparoscopic surgery b...

Abstract Power electronic converters must be researched and developed to offer high-power, low-cost, reliable contributions solving the electric vehicle battery problem in light of widespread usage expected rise EVs. An adequate charging infrastructure is required accommodate growing number cars (EVs). Off-board chargers for vehicles (EVs) are talked about here, along with their alternating cur...

This paper proposes a new approach for implementing fast multicast and broadcast in multistage interconnection networks (MINs) with multiport encoded multidestination worms. For a MIN with k k switches and n stages such worms usen header flits each. One flit is used for each stage of the network and it indicates the output ports to which a multicast message must be replicated. A single multipor...

<span lang="EN-US">As the load demand continues to rise on a daily basis, there will be an increased requirement for sources of renewable energy. When compared building entire power system, cost distributed generation, also known as DG, is significantly lower, which makes it useful tool fulfilling electricity. However, these DG are built utilizing energy, by their very nature intermittent...

The partial power processing (PPP) concept has been extensively employed in many two-port converters to achieve high efficiency and high-power density by modifying one of the original converter ports be connected series between input output. This is attractive but confined applications, how extend it multiport applications not clear. Hence, this article aims explore a generalized PPP scheme arr...
