RSS phaseMicrosoft, Yahoo! talks: In the "off-again" phase
News are firmly in the "off-again" phase. Microsoft CEO Steve Ballmer said Thursday that its on-again, off-again talks with Yahoo! The two sides have talked on and off, he said, first about a purchase and then about a search deal. [25 Jul 2008]
Making IT Invisible: NetApp Storage for Virtual Server Environments
White Paper Conversion between these two vastly different states is called a phase transition which is exactly what IT needs to undergo to become invisible. The goal of IT is to become an invisible entity within a larger scale organization--an entity that can... [24 Jul 2008]
London City Hall Gets High-Tech Makeover From Foundry and Mitel
White Paper London City Hall wanted an integrated, modern communications infrastructure with fast links to transnational offices and the ability for workers to telecommute and a scalable solution that would support gradual phase-in of VoIP and other IP... [18 Jul 2008]
Preconfiguring IP-Over-Optical Networks to Handle Router Failures and Unpredictable Traffic
White Paper In implementing this scheme, the first and second phase paths are realized at the optical layer with router packet grooming at a single intermediate node only. This paper considers the realization of traffic-oblivious routing in IP-over-Optical... [18 Jul 2008]
Fast FIR Filters for SIMD Processors With Limited Memory Bandwidth
White Paper Finite impulse response filters are easy to design, unconditionally stable, phase linearity is easily obtained. FIR filtering is one of the most populars DSP algorithms. Also noise and rounding error analysis are easy. [11 Jul 2008]
Frequency Bandwidth Optimization of Left-Handed Metamaterial
White Paper Off late, left-handed metamaterials (LHM's) have been demonstrated with an effective negative index of refraction and with antiparallel group and phase velocities for microwave radiation over a narrow frequency bandwidth. [11 Jul 2008]
Streaming Media Congestion Control Using Bandwidth Estimation
White Paper SMCC avoids the Slow Start phase in TCP. The fundamental challenge in streaming media over the Internet is to transfer the highest possible quality, adhere to the media play out time constraint, and efficiently and fairly share the available... [11 Jul 2008]
Parameter Calibration, Customer Load Balancing and Security Aspects for Multiplexing of BPO Infrastructure
White Paper Outsourcing, during its establishment phase, focused on the socio-economic and the managerial concerns of the companies, countries and people involved. As progress toward the next generation of outsourcing, one need to ascertain a technology... [10 Jul 2008]
EquiLoad: A Load Balancing Policy for Clustered Web Servers
White Paper To study its performance, the paper uses phase-type distribution fittings and solve the resulting models using a new solution method for M/PH/1 queues that only requires solution of linear systems. This paper presents a new strategy for the... [10 Jul 2008]
Concepts for High Availability in Scientific High-End Computing
White Paper With only very few exceptions, the overall availability of recently installed systems has been lower in comparison to the same deployment phase of their predecessors. Scientific High-End Computing (HEC) has become an important tool for scientists... [10 Jul 2008]
An Integrated Approach to Recovery and High Availability in an Updatable, Distributed Data Warehouse
White Paper It compares the runtime overhead and recovery performance of HARBOR to those of two-phase commit and ARIES, the gold standard for log-based recovery, on a three-node distributed database system. Any highly available data warehouse will use some... [10 Jul 2008]
802.11 Network Intrusion Detection Using Genetic Programming
White Paper Genetic Programming (GP) based Intrusion Detection Systems (IDS) use connection state network data during their training phase. These connection states are recorded as a set of features that the GP uses to train and test solutions which allow for... [10 Jul 2008]
A Low-Noise Fast-Settling PLL With Extended Loop Bandwidth Enhancement by New Adaptation Technique
White Paper A new adaptation scheme for low noise and fast settling Phase Locked Loops (PLL's) is presented. Extended loop bandwidth enhancement is achieved by the adaptive control on the reference frequency and frequency divide ratio. [10 Jul 2008]
A Performance Study of Diffusive Vs. Remapped Load-Balancing Schemes
White Paper For a large class of irregular grid applications, the computational structure of the problem changes in an incremental fashion from one phase of the computation to another. Eventually, as the graph evolves, it becomes necessary to correct the... [10 Jul 2008]
BEA Systems Case Study: VECTREN
White Paper The first phase of the migration onto a rationalized portal infrastructure was to implement Vectren's employee portal on BEA WebLogic Portal 8.1. Vectren wanted to cut IT expenses by simplifying and accelerating development and integration projects... [10 Jul 2008]
