In this research, we study the multi-skill resource-constrained project scheduling problem, where there are generalized precedence relations between project activities. Workforces are able to perform one or several skills, and their efficiency improves by repeating their skills. For this problem, a mathematical formulation has been proposed that aims to optimize project completion time, reworki...

relying upon the theories concerned with the cultural evolution of anthropology and archaeology, and providing a brief review of the related literature, the present article conducts a careful examination of the evolutionary trends in pottery of the layers from the prehistoric periods of qal’eh kh?n. testing several variables affecting pottery, the article proposes that while cultural evolutioni...

We reevaluate evidence for luminosity evolution in the intermediate-redshift Tully-Fisher relation (TFR), focusing on the spatially resolved kinematic data sets of Vogt et al. (1997) and Simard & Pritchet (1998). We use low-z data from the Nearby Field Galaxy Survey (NFGS) to match the intermediate-z studies' sample selection criteria, analysis techniques, and data quality. The passively evolvi...
