Attaining highly secure and safe operation of the grid with acceptable voltage levels has become a difficult issue for electricity companies that must adopt remedial actions. The usage PV solar farm inverter as static synchronous compensator (or PVSTATCOM device) throughout night recently been proposed way to enhance system performance. In this article, novel artificial rabbits’ optimization al...

We conjecture that local theta correspondence can be normalized by the leading coefficient of a weighted local period integral, and that there exists a duality of local and global inner product formulas. The conjecture is verified for the pair ( SL2, PGL2) and (SL2, SO(2, 2)). As an application, global inner product formulas are obtained for liftings in the directions PGL2 → SL2, GSO(2, 2) → GL2.

Facial Emotion Expressions plays an important role in interpersonal relations.This is because human convey lot of information visually than verbally.To automate recognition of emotion state,machine should taught to understand facial guestures.In this paper we classify emotion expression through Support Vector Machine(SVM) & Hidden Markov Model (HMM),then Hidden Markov Model is optimized using G...

This article is intended to provide an overview of various aspects of clinical PET/CT. These include discussions of: (i) Important areas of clinical application; (ii) Opportunities in clinical research; (iii) Scanner and operating-mode considerations (e.g. BGO vs. LSO, LYSO or GSO scanners, 2D vs. 3D imaging). (iv) Study-specific considerations (e.g. patient preparation and positioning issues, ...

Global Navigation Satellite Systems (GNSSs) are the most widespread technology for Position and Timing (PNT). They have been traditionally deployed exploiting Medium Earth Orbit (MEO) or Geosynchronous (GSO) satellites. To meet future demands overcome MEO GSO limitations, GNSSs based on Low (LEO) constellations investigated as a radical system change. Although characterized by higher Doppler ef...

Over the last few decades, tremendous and exponential expansion in digital contents together with their applications has emerged. The Internet represents essential leading factor for this expansion, which provides low-cost communication tools worldwide. However, main drawback of is related to security problems. In order provide secure communication, enormous efforts have been spent cryptographi...

Scintillating crystal detectors offer potential advantages in low-energy low-background experiments for particle physics and astrophysics. The GSO crystal is an interesting detector to explore for future neutrino physics experiments. The contributions to background due to the various channels of intrinsic radio-isotopes from the 232 Th and 238 U series are identified and studied with time-corre...
