Blowing up hard drives, stinky broadband and super cars
Photo This piece of equipment measures a patient's blood oxygen level and takes their pulse - in this case a plucky volunteer guinea pig has 98 per cent blood oxygen and a very low resting pulse rate of 47. [01 Aug 2008]
Ovum Report: IBM Simplfies Service Management to facilitate business and IT
White Paper This whitepaper reports on IBM's recent Pulse 2008 conference, which explored how IT Managers can simplify and leverage their IT services and infrastructure, to bring a more holistic approach to IT within the business [31 Jul 2008]
Ultra Low Latency Optical Networks
White Paper Employed techniques include a non-blocking, bufferless topology, single pulse packets incorporating Wavelength Division Multiplexing (WDM) for both routing header and payload data, and ultra-fast electro optical interfaces built from commercially... [18 Jul 2008]
Photos: It's virtual everything in Cisco's future
Photo This piece of equipment measures a patient's blood oxygen level and takes their pulse - in this case a plucky volunteer guinea pig has 98 per cent blood oxygen and a very low resting pulse rate of 47. [16 Jul 2008]
On the Scalability of Cooperative Time Synchronization in Pulse-Connected Networks
White Paper The problem of time synchronization in dense wireless networks is considered. Well established synchronization techniques suffer from an inherent scalability problem in that synchronization errors grow with an increasing number of hops across the... [11 Jul 2008]
Anytime Coding on the Infinite Bandwidth AWGN Channel: A Sequential Semi-Orthogonal Code
White Paper This paper shows that it is possible to do this using a semi-orthogonal variation of pulse position modulation that is sequential in nature - bits can be "Streamed out" without having to buffer up blocks of bits at the transmitter. [11 Jul 2008]
Convergence Analysis of Iteratively Detected Time Hopping and DS-CDMA Ultrawide Bandwidth Systems by EXIT Charts
White Paper The analysis is based on the Extrinsic Information Transfer (EXIT) chart where the UWB systems are serially concatenated pulse-position modulated TH and code-synchronous DS-CDMA. This paper presents a novel analysis on the decoding convergence of... [11 Jul 2008]
High Bandwidth-Efficiency Solar-Blind AlGaN Schottky Photodiodes With Low Dark Current
White Paper AlGaN-based solar-blind photodetectors with very low leakage and noise levels, high responsivity, high detectivity, and fast pulse response have been reported. Solar-blind UltraViolet (UV) detectors with cut-off wavelength around 280nm can sense... [11 Jul 2008]
Frequency and Bandwidth Agile Pulser for Use in Electrical and Biological Effects Testing
White Paper This paper presents a Blumlein based pulse generator designed to be tunable in both center frequency and bandwidth. The pulse width is determined by moving the center conductor in and out of the Blumlein region, and the bandwidth is set by... [10 Jul 2008]
Pulse Shaping on the Palm Pilot
White Paper The paper also describes how to communicate with a PC or device through a serial line by directly manipulating pins to create a pulse train. This White paper looks at low level programming of the Palm Pilot, especially its Motorola MC68EZ328... [03 Jul 2008]
Pulse Entertainment Reduces Hosting Costs With the Help of IBM
White Paper Founded in 1994, Pulse Entertainment (www.pulse3d.com) has established itself as a leader in character-driven interaction for the Web. Many of its customers use Pulse-powered solutions to reach thousands or even millions of people. [03 Jul 2008]
A Predistorter for OFDM Systems With a Raised Cosine Pulse Shaping Filter and a High Power Amplifier
White Paper In this paper, a predistorter is presented for the orthogonal frequency division multiplexing (OFDM) systems with a transmit raised cosine (RC) pulse shaping filter and a high power amplifier (HPA). By exploiting zero-intersymbol interference (ISI... [03 Jul 2008]
Comparison of Multi-Processor Power PC Board Architectures for Pulse-Doppler Radar Processing
White Paper The Distributed Memory architecture has dominated multi-processor solutions for radar processing. Early hardware was custom designed boards based on bit-slice processing engines; and then more recently, commercial-off-the-shelf (COTS) hardware that... [03 Jul 2008]
Senator Keeps Finger on Pulse of Constituency With HP Digital Sender And HP Autostore
White Paper Senator Edward M. Kennedy has represented Massachusetts in the United States Senate for forty years. The Senator office needed a system to help Senator Kennedy efficiently to meet the needs of his constituents, cope with security issues and process... [03 Jul 2008]
CDMA Waveform Generation for Digital Radios
White Paper The digital modulator performs pulse shaping on input complex data streams and then interpolates those signals to a multiple of the chip rate. Graphs demonstrate the effect of pulse shaping and CDMA user loading on the transmitted waveform's peak... [03 Jul 2008]
