This paper studies the statistical errors for the fingerprint-based RADAR neighbor matching localization with the linearly calibrated reference points (RPs) in logarithmic received signal strength (RSS) varying Wi-Fi environment. To the best of our knowledge, little comprehensive analysis work has appeared on the error performance of neighbor matching localization with respect to the deployment...

Information systems development projects (ISDPs) are facing significant challenges due to changes in business and IT environments. To improve IS performance, ISDPs require flexibility to respond to various changes during the project lifecycle. Drawing upon the flexibility literature and contingency perspectives, this research examines the main effect of ISDP flexibility on IS performance using ...

To think quantitatively about comovement, we specify the model of Section I. We use a CES production function for one final good. 42 Thus, we can solve the structure of this economy in closed form, and quantify its comovement. Our model differs in a series of small ways from 43 Its main virtue is that it is solvable in closed form, so that the mechanisms are fairly transparent.

Page 12 meeting initiator. For instance, the meeting chair and secretary must be present; they have the highest participant importance. In a project meeting where specific tasks are discussed, task leaders would have a higher importance than normal project members and a lower importance than the meeting chair, the task speakers or the project reviewers. Meeting Significance. The meeting signifi...

In this article we show how a project’s option value increases with incremental levels of investment and dis-investment flexibility. We do this by presenting two NPV and seven option pricing models in a strict sequence of increasing flexibility. We illustrate each with numerical examples and determine the maximum value that a project option could ever support. We show that managerial considerat...

Conditionals —i.e., switch statements, nested ifs— that are used to simulate polymorphism hamper evolution and flexibility of applications. The reengineering patterns presented in this paper show you how to transform conditionals in object-oriented code to improve the flexibility of application. This work has been funded by the Swiss Government under Project no. NFS-2000-46947.96 and BBW-96.001...

Surveys on system development (SD) project performance suggest that while much improvement has been made in SD technology, the project success rate remains low. SD research based on the socio-technical perspective suggests that three sources of socio-technical change have a bearing on the performance of SD projects: business requirements, development technology, and development procedures. To e...

I describe two studies that were designed to illustrate the potential applicability of laboratory-derived ESP effects in trying to predict events of practical consequence in the “real world.” Both studies attempt to predict the behavior of sets of fi nancial indices over a designated week in the future. The studies followed up on earlier work on the prediction of scoring direction and scoring e...

Abstract—Concurrent planning of project scheduling and material ordering can provide more flexibility to the project scheduling problem, as the project execution costs can be enhanced. Hence, the issue has been taken into account in this paper. To do so, a mixed-integer mathematical model is developed which considers the aforementioned flexibility, in addition to the materials quantity discount...
