The next generation of power systems faces significant challenges, both in coping with increased loading of an aging infrastructure and incorporating renewable energy sources. Meeting these challenges requires a fundamental change in the operation of power systems by replacing human-in-theloop operations with autonomous systems. This is especially acute in distribution systems, where renewable ...

The EPIC pn CCD camera on board of XMM-Newton is designed to perform high throughput imaging and spectroscopy as well as high resolution timing observations in the energy range of 0.1–15keV. A temporal resolution of milliseconds or μ-seconds, depending on the instrument mode and detector, is outstanding for CCD based X-ray cameras. In order to calibrate the different observing modes of the EPIC...

We present measurements of the true masses and orbital inclinations of the two Earth-mass planets in the PSR B1257+12 system, based on the analysis of their mutual gravitational perturbations detectable as microsecond variations of the arrival times of radio pulses from the pulsar. The 6.2-millisecond pulsar, PSR B1257+12, has been regularly timed with the Arecibo telescope since late 1990. Ass...

The single-pulse properties of the millisecond radio pulsar PSR B1937+21 are studied in the 1410 MHz radio band. Aside from occasional “giant pulses” occurring in restricted regions of pulse phase, the emission appears to be remarkably stable, showing no pulse-to-pulse fluctuations other then those induced by propagation through the interstellar medium. This type of behavior has not been seen i...

We present a detailed study of the single radio pulses of PSR B0656+14. The emission can be characterized by two separate populations of pulses: bright pulses have a narrow " spiky " appearance in contrast to the underlying weaker broad pulses. The shape of the pulse profile requires an unusually long timescale to achieve stability (over 25,000 pulses at 327 MHz) caused by spiky emission. The e...

We summarize the detections of extreme ultraviolet (EUV) emission from neutron stars. Three rm detections have been made of spin-powered pulsars: the aged millisecond pulsar PSR J0437?4715, the middle-aged X-ray pulsar Geminga, and the radio pulsar PSR B0656+14. These observations allow us to evaluate both power-law and thermal-law emission models as the source of the EUV ux. For the case of PS...

Over the last decade, considerable effort has been made to measure the proper motions of the pulsars B1757−24 and B1951+32 in order to establish or refute associations with nearby supernova remnants and to understand better the complicated geometries of their surrounding nebulae. We present proper motion measurements of both pulsars with the Very Large Array, increasing the time baselines of th...

Aims and Objectives Self-rated oral health is the key element that has a greater effect on quality of life and found to be authentic and logical to consider this as an indicator for overall oral health status. The aim was to investigate and identify the impact of various social and clinical factors on the perceived self-rated oral health status (PSR-OHS). Materials and Methods A self-administ...

Robots have been used in several new applications. In recent years, both academic and commercial research has been focusing on the development of a new generation of robots in the emerging field of service robots. Service robots are individually designed to perform tasks in a specific environment for working with or assisting humans and must be able to perform services semior fully automaticall...

A new classification of neutron star cooling scenarios, involving either “minimal” cooling or “enhanced” cooling is proposed. The minimal cooling scenario replaces and extends the so-called standard cooling scenario to include neutrino emission from the Cooper pair breaking and formation process. This emission dominates that due to the modified Urca process for temperatures close to the critica...
