- Phase Wise Cost Analysis of a Project
- The cost component is vital to the success of any software project. Most of the failure projects attribute themselves to incorrect cost estimates and budget allocations. Many software projects fail not because there is no market, but because the cost of creating the software far outstrips any profit. Exponential costs...

- TCP With Variance Control for Multihop IEEE 802.11 Wireless Networks
- This paper argues that a cause of poor performance of TCP NewReno in wireless ad hoc networks is the use of packet drop as feedback for window adjustment. While packets can be dropped because of wireless congestion/interference, it is true however that these losses are typically recovered by link level...

- Application Performance Management: Using Veritas i3 for Oracle Applications
- To compete in today's information-rich environment, organizations require ERP assets like Oracle Applications OA to deliver three strategic attributes: fast response to end users, high data handling efficiency, and compelling business process differentiation. However, none of these attributes are inherently part of these off-the-shelf applications. User customizations, differences in usage...

- More than You Ever Wanted to Know about Volatility Swaps (But Less than Can Be Said)
- In this report we explain the properties and the theory of both variance and volatility swaps, first from an intuitive point of view and then more rigorously. The theory of variance swaps is more straightforward. We show how a variance swap can be theoretically replicated by a hedged...

- Conduct Variance Analysis
- A person spends hours performing a variance analysis each month after he closes the books. This webcast shows how to perform this task more efficiently by using Microsoft Office Excel 2003, which will help one to spot trends, issues, or opportunities that could affect the company's economic success.

- Try, Try Again: Replication-Based Variance Estimation Methods for Survey Data Analysis in SAS 9.2
- Complex survey samples are constructed with selection schemes that affect the usual random assumptions, so SAS/STAT software provides specialized procedures to analyze them: SURVEYMEANS, SURVEYFREQ, SURVEYREG, and SURVEYLOGISTIC for means, frequencies, regression, and logistic analysis, respectively. These procedures all use the Taylor series expansion method for variance estimation, which is...

- Models and Solutions for Radio Irregularity in Wireless Sensor Networks
- This paper investigates the impact of radio irregularity on wireless sensor networks. Radio irregularity is a common phenomenon which arises from multiple factors, such as variance in RF sending power and different path losses depending on the direction of propagation. From the experiments, the paper discovers that the variance in...

- Pilot-Aided Channel Estimation for Systems With Virtual Carriers
- This paper investigates various frequency-domain channel estimators for Orthogonal Frequency Division Multiplexing OFDM systems with Virtual Carriers VCs. As conventional estimators cannot estimate the Channel Transfer Function CTF at VCs, DFT-based estimators are not directly applicable in OFDM systems with VCs. To circumvent this, the authors present Least Squares LS,...

- Investigate an agile, lightweight, "value-up" approach to software engineering
- Most accepted project management wisdom comes from the world of roads and bridges, where design risks are low, design cost is small relative to build cost, and the opportunity to to deliver incremental value is rare. This "work-down" approach is easily envisioned as burning down a list of tasks, and...
