Zero-current (ZC) switching pulse-widthmodulated (PWM) flyback DC-DC converter is an extended version of the single switch flyback converter with an additional active circuit. The purpose of the active circuit is to turn-off the main switch with zero-current switching (ZCS) condition to reduce the turn-off switching loss. This paper presents an overview of the ZCS flyback PWM DCDC converters. T...

Video inpainting is often used as a tool to assist user in removing objects or repairing damaged areas in a video. Scratch detection and removal are important subjects for video restoration. Line scratches are main problems in motion films. Such problems may produce a very annoying effect on the viewer. Many algorithms have been developed so far among which some are directly extended from the i...

The information available on web pages mostly contains semi-structured text documents which are represented either in XML, or HTML, or XHTML format that lacks formatted document structure. The document does not discriminate between the text and the schema that represent the text. Also the amount of structure used to represent the text depends on the purpose and size of text document. No semanti...

To a first approximation, self-representationalism is the view that a mental state M is phenomenally conscious just in case M represents itself in the appropriate way. Proponents of self-representationalism seem to think that the phenomenology of ordinary conscious experience is on their side, but opponents seem to think the opposite. In this paper, I consider the phenomenological merits and de...

Wireless Sensor Networks (WSN) is becoming the heart of many applications. Data integrity and security is a major issue as the wireless sensor nodes are exposed to harsh and hostile environment. This paper highlights the merits and demerits of different key management schemes under the broader classification of Public Key Infrastructure (PKI), Identity Based Encryption (IBE) and Certificateless...

operations are now distinguished, viz., tonsillotomy, in which only a slice of the enlarged tonsil is removed, and tonsillectomy, in which the whole tonsil is removed with its capsule intact. The former operation is carried out with a guillotine, the latter by dissection. The merits or demerits of the rival operations I do not propose to discuss. To those interested in the question, both sides ...

This Article contains some reflections concerning the Draft Treaty establishing a Constitution for Europe (“the Draft Treaty”), which was approved by the European Council on September 28, 2004 and formally signed in Rome on October 29, 2004. At the time of writing in early 2005, it is presently in the process of ratification by the twenty-five Member States of the European Union (“EU”). The Art...

This paper introduces a semantic model for vague quantifiers (VQs) combining Fuzzy Theory (FT) and Supervaluation Theory (ST), which are the two main theories on vagueness, a common source of uncertainty in natural language. After comparing FT and ST, I will develop the desired model and a numerical method for evaluating truth values of vague quantified statements, called the Modified Glöckner’...

Videos and images reveal many interesting and useful information which can serve the mankind in many ways. Researchers and professionals are motivated in studying and exploring the information in conditioned and unconditioned environment. In the literature there are many models built to detect and track the movement of the object, each one of the models built has its own advantages and limitati...

Continuous positive airway pressure (CPAP) is a simple, inexpensive and gentle mode of respiratory support in preterm very low birth weight (VLBW) infants. It helps by preventing the alveolar collapse and increasing the functional residual capacity of the lungs. Since it results in less ventilator induced lung injury than mechanical ventilation, it should theoretically reduce the incidence of c...
