The nonlinear load such as UPS, fan controller, mobile charger is distorting the supply current waveform. This current harmonics derates the power system equipment. To avoid this current harmonics, filters namely passive filter / active filter /hybrid filters are introduced in the supply line. In this paper the overall view of the performance of the various filters are studied and the performan...

As parallel machines become more widely available, many existing algorithms are being converted to take advantage of the improved speed offered by such computers. However, the method by which the algorithm is distributed is crucial towards obtaining the speed-ups required for many real-time tasks. This paper presents three parallel implementations of the Douglas-Peucker line simplification algo...

Let X be a smooth projective surface. Here we study the postulation of a general union Z of fat points of X, when most of the connected components of Z have multiplicity 2. This problem is related to the existence of ”good” families of curves on X, with prescribed singularities, most of them being nodes, and to the cohomology of suitable line bundles on blowing ups of X. More precise statements...

In this paper we prove a conjecture by Feldman-IlmanenKnopf in [14] that the gradient shrinking soliton metric they constructed on the tautological line bundle over CP is the uniform limit of blowups of a type I Ricci flow singularity on a closed manifold. We use this result to show that limits of blow-ups of Ricci flow singularities on closed four dimensional manifolds do not necessarily have ...

A novel pulse-width modulated (PWM) single-phase line-interactive uninterruptible power supply (UPS) based on the small dc bus capacitor is presented. The proposed system is made up of an ac chopper which includes a diode rectifier, a boost switch, a charger and an inverter. It has the features of a small dc bus capacitor, small input and output inductors, and low switching loss, and is very su...

Let H and H ′ be two ample line bundles over a smooth projective surface X , and M(H) (resp. M(H )) the coarse moduli scheme of H-semistable (resp. H -semistable) sheaves of fixed type (r, c1, c2). We construct a sequence of blowing-ups which describes how M(H) differs from M(H ) not only when r = 2 but also when r is arbitrary. Means we here utilize are elementary transforms and the notion of ...

Confusion-matrices show that character mix-ups between similar looking letters differing in size rather than in shape (like “s” and “S” or “e” and “l”), as well as between tall letters (such as “M” and “t”) and small case letters (such as “s” and “a”) and vice versa can occur in on-line whiteboard note recognition. This paper introduces a novel feature called “line-member” feature that adds dis...

Previous work indicates that intranasal inhalation of oxytocin improves face recognition skills, raising the possibility that it may be used in security settings. However, it is unclear whether oxytocin directly acts upon the core face-processing system itself or indirectly improves face recognition via affective or social salience mechanisms. In a double-blind procedure, 60 participants receiv...

introduction: acute pain and swelling following endodontic treatment are challenges for patients and dentists. according to previous studies, the incidence of flare-ups increases after endodontic treatment of teeth with necrotic pulp. calcium hydroxide is currently used as a multipotential medicament in root canal therapy. the aim of this study was to evaluate the incidence and severity of flar...

It is believed that a strong core will enable an athlete to effectively transfer forces from the lower extremities through torso upper extremities. Control of shoulder girdle force important for proper function extremities, although stabilising trunk and pelvis are also important. The purpose this study determine association between isometric push-up/pull-down strength abdominal muscles. Using ...
