Hypocoercivity for kinetic equations with linear relaxation terms

Jean Dolbeault, Clement Gabriel Mouhot & Christian Schmeiser
This note is devoted to a simple method for proving hypocoercivity of the solutions of a kinetic equation involving a linear time relaxation operator, i.e. the construction of an adapted Lyapunov functional satisfying a Gronwall-type inequality. The method clearly distinguishes the coercivity at microscopic level, which directly arises from the properties of the relaxation operator, and a spectral gap inequality at the macroscopic level for the spatial density, which is connected to the diffusion limit....

MIPAS reduced spectral resolution UTLS-1 mode measurements of temperature, O₃, HNO₃, N₂O, H₂O and relative humidity over ice: retrievals and comparison to MLS

S. Chauhan, M. Höpfner, G.P. Stiller, T.Von Clarmann, B. Funke, N. Glatthor, U. Grabowski, A. Linden, S. Kellmann, M. Milz, T. Steck, H. Fischer, L. Froidevaux, A. Lambert, M.L. Santee, M. Schwartz, W.G. Read & N.J. Livesey
During several periods since 2005 the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on Envisat has performed observations dedicated to the region of the upper troposphere/lower stratosphere (UTLS). For the duration of November/December 2005 global distributions of temperature and several trace gases from MIPAS UTLS-1 mode measurements have been retrieved using the IMK/IAA (Institut für Meteorologie und Klimaforschung/ Instituto de Astrof´ısica de Andalucía) scientific processor. In the UTLS region a vertical resolution of 3 km...

Dynamic Idp Signature Processing By Fast Elimination Using Dfa

Mohammed Misbahuddin, Sachin Narayanan & Bishwa Ranjan Ghosh
ABSTRACT Intrusion Detection & Prevention Systems generally aims at detecting / preventing attacks against Information systems and networks. The basic task of IDPS is to monitor network & system traffic for any malicious packets/patterns and hence to prevent any unwarranted incidents which leads the systems to insecure state. The monitoring is done by checking each packet for its validity against the signatures formulated for identified vulnerabilities. Since, signatures are the heart & soul of an...

A New Key Establishment Scheme For Wireless Sensor Networks

Eric Ke Wang, Lucas C.K.Hui & S.M.Yiu
ABSTRACT Traditional key management techniques, such as public key cryptography or key distribution center (e.g., Kerberos), are often not effective for wireless sensor networks for the serious limitations in terms of computational power, energy supply, network bandwidth. In order to balance the security and efficiency, we propose a new scheme by employing LU Composition techniques for mutual authenticated pairwise key establishment and integrating LU Matrix with Elliptic Curve Diffie-Hellman for anonymous pathkey establishment. At the...

Iterative Method For Improvement Of Coding And Decryption

Natasa Zivic
Cryptographic check values (digital signatures, MACs and H-MACs) are useful only if they are free of errors. For that reason all of errors in cryptographic check values should be corrected after the transmission over a noisy channel before their verification is performed. Soft Input Decryption is a method of combining SISO convolutional decoding and decrypting of cryptographic check values to improve the correction of errors in themselves. If Soft Input Decryption is successful, i.e. all...
