The non-destructive inspection of large concrete walls with autonomous systems is still an unsolved problem. One of the main difficulties is to develop a very flexible platform, which is able to move and inspect horizontal and vertical surfaces safely, fast and cost-efficient. This report will present the climbing robot Cromsci which is designed for the described task. The propulsion system con...

The size and complexity of websites have grown significantly during recent years. In line with this growth, the need to maintain most of the resources has been intensified. Content Management Systems (CMSs) are software that was presented in accordance with increased demands of users. With the advent of Content Management Systems, factors such as: domains, predesigned module’s development, grap...

With increasing expenses for future HPC centers, the need to look at their productivity, defined as amount of science per total cost of ownership (TCO), grows. This includes development costs which arise from development effort spent to parallelize, tune or port an application to a certain architecture. Development effort estimation is popular in software engineering, but cannot be applied dire...

  These days, data mining one of the most significant issues. One field data mining is a mixture of computer science and statistics which is considerably limited due to increase in digital data and growth of computational power of computer. One of the domains of data mining is the software cost estimation category. In this article, classifying techniques of learning algorithm of machine ...

Reliable effort estimation remains an ongoing challenge to software engineers. Accurate effort estimation is the state of art of software engineering, effort estimation of software is the preliminary phase between the client and the business enterprise. The relationship between the client and the business enterprise begins with the estimation of the software. The credibility of the client to th...

Estimating the effort of software development is fraught with difficulties, and it is clear that effort should be invested in improving the accuracy and the reliability (consistency) of effort estimates, as well as the assessment of estimate uncertainty. However, it is less clear where to target such improvement efforts. We discuss the degree to which it is feasible to improve the expertise of ...

The four studies included in this paper examine the strength of the first impression in the estimation of work effort. The studied context is mainly one where the first impressions of software development effort is manipulated (biased) through comparisons with either much too low or too high reference effort values, e.g., by responding to a question from the client whether one believes that the...

Calibration, has been .found to be difficult in practice. Wide experience in using the estimation model is necessary; experience which the beginner naturally lacks. This paper indicates why it is important to calibrate a model and how the inexperienced user can be helped by an expert system. In addition, the development of, and experience with, the prototype of an expert system are described. T...
