Spectral Density Bandwidth Choice and Prewhitening in the Generalized Method of Moments Estimators for the Asset Pricing Model
White Paper A Monte Carlo study is conducted to evaluate the issues of estimating the spectral density functions, e.g.parametric vs.nonparametric, data - based bandwidth selection, and prewhitening procedures. Therefore, there exists efficiency/bias trade-off... [11 Jul 2008]
Handspring Treo Reduces Administrative Workload in Home Healthcare
White Paper After the deployment, STNBO is estimating a return on investment after a mere 10-12 months. In an effort to improve efficiency and thereby lower costs, STBNO (Stichting Thuiszorg Brabant Noord-Oost), which is a Dutch outpatient healthcare provider... [03 Jul 2008]
Synchronization in Interleaved OFDMA Systems
White Paper This paper investigates the base station receiver signal structure, and a structure based estimator is proposed for simultaneously estimating multiple users' carrier frequency offsets. Multi-carrier communications increase the efficiency and... [03 Jul 2008]
Radius Solutions Case Study: Display Pack
White Paper Its business management software was a custom-developed mainframe system, which lacked important capabilities, including a robust estimating system, complete business integration, and the ability to deliver critical information about the company's... [05 Jun 2008]
Accurately Measuring Datacenter Power Efficiency Timely and accurate measurements with SunSM Eco Services
White Paper Taking accurate measurements takes time, however, and a statistical model built from a set of baseline measurements provides a means of closely estimating efficiency improvements even while a datacenter is in a state of constant change. [14 May 2008]
Electrical Efficiency Modeling of Data Centers
White Paper Conventional models for estimating electrical efficiency of data centers are grossly inaccurate for real-world installations. This paper shows that the values commonly used for estimating equipment inefficiency are quite inaccurate. [26 Apr 2008]
Estimating Financing Needs for Local Services in Madagascar
White Paper A study in Madagascar offers a methodology for conducting such assessments, which should be complemented by tools that measure the efficiency and quality of public spending. As more countries decentralize public services, there is a growing need to... [10 Apr 2008]
Shell signs $4bn IT outsourcing contract
News But transferred staff will not retain their existing rights and redundancy packages under their new employers, with Shell estimating these will expire after about two years. The oil multinational expects "significant improvements in efficiency and... [31 Mar 2008]
Photos: BlackBerrys on the beat
Photo West Yorkshire Police, pictured here, is another force which uses the BlackBerry, with the force estimating its use has resulted in £8.8m in efficiency savings and saved 145-hours per front-line officer per year. [08 Feb 2008]
IT at your service
Comment It's about being much more polished and accurate in estimating. One way of surmounting that problem is to ensure an IT department's processes are configured for efficiency and for consistency when it comes to customer service, says Everson. [09 Jan 2008]
CTCP: Improving TCP-Friendliness Over Low-Buffered Network Links
White Paper However, CTCP requires detecting incipient congestion effectively by estimating the backlogged packets and comparing it to a pre-defined parameter gamma. CTCP is a synergy of delay and loss-based congestion control, effectively combining them to... [19 Dec 2007]
Efficient Independent Component Analysis
White Paper Many statistical techniques based on M-estimates have been proposed in estimating the mixing matrix. However, in-depth analysis on asymptotic efficiency has not been available. Independent component analysis (ICA) has been widely used for blind... [19 Jul 2007]
Minimum-Output-Energy Method for Blind Equalization of OFDM and Systems With Sufficient or Insufficient Cyclic Prefix
White Paper Algorithms are developed for blindly estimating the constraints and equalizers. Therefore, it provides an effective way to improve bandwidth efficiency with shorter cyclic prefix length. In this paper, a new blind equalization method is proposed... [11 Apr 2007]
Estimating the Efficiency of Collaborative Problem-Solving, With Applications to Chip Design
White Paper In this paper, the authors present a statistical framework to address questions that arise in general problems involving collaboration of several contributors. One instance of this problem occurs in the complex process of designing UltraLarge-Scale... [08 Feb 2007]
A Fast Downsizing Video Transcoder for H.264/AVC With Rate-Distortion Optimal Mode Decision
White Paper A model for estimating relative prediction errors is applied in this paper, which is free from computation interpolation and SAD/SSD computation. A fast downsizing transcoding scheme is developed in which a new Rate-Distortion (R-D) optimal mode... [07 Sep 2006]
