Deploying Grid technologies by distributing an application over several machines has been widely used for scientific simulations, which have large requirements for computational resources. The Grid Configuration Manager (GCM) is a tool developed to ease the management of scientific applications in distributed environments and to hide some of the complexities of Grids from the end-user. In this ...
[1] We show that a simple model of pan evaporation (‘‘PenPan’’) can be used to analyze monthly mean output from a global climate model (GCM). PenPan is based on a modified version of Penman’s potential evapotranspiration equation. Very good agreement is obtained with observed annual pan evaporation for Australian sites when PenPan is forced by surface observations of radiation, wind speed, humi...
This paper presents the use of the generalized classical method (GCM) for solving linear and nonlinear differential equations. This method is based on the differential transformation (DT) technique. In the GCM, the solution of the nonlinear transient regimes in the physical processes can be written as a functional series with unknown coefficients. The series can be chosen to satisfy the initial...
The impact of representing inhomogeneous cloud structure in a global climate model (GCM) using a sub-column cloud generator and the Atmospheric Environmental Research, Inc. (AER) GCM radiation model, RRTMG, which has been modified to use, the Monte-Carlo Independent Column Approximation (McICA) (Pincus et al. 2003), has been examined in the National Center for Atmospheric Research (NCAR) Commun...
Increasingly accelerated urbanization and socio-economic development can cause a series of environmental problems. Accurate and efficient monitoring of the geographical conditions is important for achieving sustainable development. This paper presents the first results of the project “Geographical Conditions Monitoring (GCM)” in an exemplified area “Beijing-Tianjin-Hebei (BTH)” in China over th...
The recently introduced Galois/Counter Mode (GCM) of operation for block ciphers provides both encryption and message authentication, using universal hashing based on multiplication in a binary finite field. We analyze its security and performance, and show that it is the most efficient mode of operation for high speed packet networks, by using a realistic model of a network crypto module and e...
Software certification has become more and more popular, especially for software developers, as it can provide confidence to customers that the product is of acceptable quality. Software certification can be done at two levels: the development process and the software product itself. There are many different certification schemes, such as ISO 9001 and CMM for development process, and Y2K compli...
This article presents an extension of the Fractal component model targeted at programming applications to be run on computing grids: the Grid Component Model (GCM). First, to address the problem of deployment of components on the Grid, deployment strategies have been de ned. Then, as Grid applications often result from the composition of a lot of parallel (sometimes identical) components, compo...

Sophie Germain Counter Mode (SGCM) is an authenticated encryption mode of operation, to be used with 128-bit block ciphers such as AES. SGCM is a variant of the NIST standardized Galois / Counter Mode (GCM) which has been found to be susceptible to weak key / short cycle forgery attacks. The GCM attacks are made possible by its extremely smooth-order multiplicative group which splits into 512 s...
