Time-cost trade-off is one of the most important subjects in project management and of interest to contractors. The goal of time-cost trade-off is sensivity analysis of project costs to changes in activity duration in order to obtain the best combination of activity duration decrease, in a way that the sum of project costs is minimized. In the heuristics presented in this area, time crashing is...

In this article, we discuss the procedure for computing values of unknowns under condition minimum sum squares observation residuals (least-squares method), taking into account errors in unknowns. Many authors have already presented problem, especially field regression analysis and computations transformation parameters. We present an overview theoretical foundations least-squares method extens...

Affective computing systems are software systems that take in account the emotional state of the user during their operation. Recently it is increasingly accepted that combining emotional with intellectual processing makes a system both more realistic and more intelligent. As such, affective computing systems are considered by many to represent the highest form of artificial intelligence and th...
