Investigations by Courvoisier, Fournel, Ducrot, Kolsky, and Koetschet in 1953 had shown that chlorpromazine reduces convulsions in mice after coramine and in rabbits after nicotine Therefore, the drug seemed to suggest itself as an anticonvulsant in epilepsy But in 1954 Bente and Itil, De Castro and Brard, and Mayr and Lechner observed activation of the electroencephalogram (E.E.G.) in epilepsy...

The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. Given the strong broad line region emission defining this blazar class, and the resulting high optical depth for VHE (E > 100 GeV) γ-rays, it was surprising to detect VHE emissio...

In this work a distributed video surveillance system based on a Client-Server architecture is presented. The proposed system is accessible from portable devices such as tablets, smartphones, etc. In a typical real-world scenario, for example in homeland security, it is useful to have portable devices that can receive in real-time a frame or a sequence of frames coming from a selected camera to ...

The flat spectrum radio quasar (FSRQ) PKS 1510−089 is known for its complex multiwavelength behaviour and it one of only a few FSRQs detected in very-high-energy (VHE, E > 100 GeV) γ rays. VHE -ray observations with H.E.S.S. MAGIC late May early June 2016 resulted the detection an unprecedented flare, which revealed, first time, intranight variability this source. While common timescale 1.5 ...

With the emergence of software delivery platforms such as Microsoft’s .NET, code compression has become one of the core enabling technologies strongly affecting system performance. In this paper, we present PPMexe a set of compression mechanisms for executables that explores their syntax and semantics to achieve superior compression rates. The fundament of PPMexe is the generic paradigm of pred...

With the emergence of software delivery platforms such as Microsoft’s .NET, code compression has become one of the core enabling technologies strongly affecting system performance. In this paper, we present compression mechanisms for executables that explore their syntax and semantics to achieve superior compression rates. The fundament of our compression codec is the generic paradigm of predic...

The PPM data compression scheme has set the performance standard in lossless compression of text throughout the past decade. PPM is a "nite-context statistical modelling technique that can be viewed as blending together several "xed-order context models to predict the next character in the input sequence. This paper gives a brief introduction to PPM, and describes a variant of the algorithm, ca...
