We present Ginga measurements of the spatial fluctuations in the diffuse X-ray background. When combined with earlier results, the new data constrain the extragalactic logN − log S relation in the 2–10 keV energy band to a form close to the Euclidean prediction over the flux range 10−10 − 5 × 10−13 erg cm−2 s−1. The normalisation of the 2–10 keV source counts is a factor 2−3 above that derived ...

The online evolution of application depends highly on its runtime environment. This paper addresses how to support applications that execute on application servers that compose of component containers and common services. From the requirement’s viewpoint, evolution of software can be divided into four categories: evolution that does not alter requirements, evolution that alters functional requi...

We present Ginga measurements of the spatial fluctuations in the diffuse X-ray background. When combined with earlier results, the new data constrain the extragalactic logN − log S relation in the 2–10 keV energy band to a form close to the Euclidean prediction over the flux range 10 − 5 × 10 erg cm s. The normalisation of the 2–10 keV source counts is a factor 2−3 above that derived in the sof...

This paper presents the simulation of Shunt Active Power filter by using two different control schemes, indirect current control technique and ANN control technique. These two controle techniques are working under both balanced and unbalanced three phase voltage source conditions and it is feeding to a adjustable speed drive the torque speed characteristics of a motor is presented. Indirect cur...

Lithium-based battery technology offers performance advantages over traditional battery technologies at the cost of increased monitoring and controls overhead. Multiple-cell Lead-Acid battery packs can be equalized by a controlled overcharge, eliminating the need to periodically adjust individual cells to match the rest of the pack. Lithium-based based batteries cannot be equalized by an overch...

this paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (apf), based on flying capacitor multicell (fcm) converter. increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of fcm converter compared with conventional multi...

This paper introduces a new topology for DC-DC converter with bipolar output and high voltage gain. The was designed the aim to use only one active power switch. Besides multiport gain this has another important feature, namely, it continuous input current. Due self-balancing outputs, proposed is suitable DC microgrids. Indeed, balancing capability can achieve two symmetrical poles of Furthermo...
