OVERWHELMING EVIDENCE DOCUMENTS a tendency toward cost and effort overruns in software projects. On average, this overrun seems to be around 30 percent.1 Furthermore, comparing the estimation accuracy of the 1980s with that reported in more recent surveys suggests that the estimation accuracy hasn’t changed much since then. (The only analyses that suggest a strong improvement in estimation accu...

S imple software cost-analysis methods are readily available, but they aren’t always safe. The simplest method is to base your cost estimate on the typical costs or productivity rates of your previous projects. That approach will work well if your new project doesn’t have any cost-critical differences from those previous projects. But it won’t be safe if some critical cost driver has degraded. ...

Paper presents procedures and experiences on using low cost desktop scanner Epson Expression 1640XL for orthophoto production. Complete process of scanning, scanner calibration and removal of systematic distortions of scanned images caused by scanner is developed and tested on several large projects of orthophoto production. Special, user-friendly software is developed for these purposes. The s...

In the field, there is a very large diversity of development processes in use, and various mixes of costs drivers, each with a different impact depending on the context. The classical approach to building estimation models in software engineering is to build a single estimation model and include within it as many cost factors (i.e. independent variables) as possible. In this paper, we do not po...

Cost estimation for large projects can be difficult because of many complex factors and uncertainties involved. It is often the case that only very rough guesses of actual costs may be provided. In this paper, we will examine the various types of uncertainties in the cost estimation problem of the Myrrha project. We will then use a few examples originated from the conceptual phase of the projec...

Two to three percent of the adult population suffer from heart failure and half of all patients with this diagnosis die within four years. To minimize life-threatening situations and costs of treatment, it is interesting to predict if a patient with known heart failure could die soon. For these reasons risk estimation of heart failure patients on the basis of collected data is described in this...

One of the major advantages of the video cameras’ usage for tracking of vehicles is to reduce the costs of Intelligent Transport Systems. However, this requires the development of software techniques allowing an automatic extraction of the vehicle or group of vehicles from the current video frame, which is possible by using the background estimation methods, assuming a fixed camera installed ov...

Rapid growth in a number of vehicles on roadways accelerates pavement deterioration trends. Pavement inefficiency in carrying the applied load from passing vehicles results in spending significant costs on continues Maintenance and Rehabilitation (M&R) treatments. Lane closure owing to the implementation of M&R operations incurs enormous costs on road users. The research aimed to calculate, and...
