In this paper, we restate some applications of logarithms in Richter scale, pH scale and sound intensity level (Decibel scale).

The Pickup and Delivery Problem (PDP) consists in defining a set of routes that satisfy transportation requests between a pickup point and a delivery point. This paper addresses a variant of the PDP where the requests are transportation demands arising from disabled persons. Vehicle passengers can change of vehicle during their trip on specific locations called “transfer points”. Solving this v...

The resulting dataset has a size of about 1; 48GB. It contains exactly 1:692:082 transactions with 5:267:656 distinct items. The maximal length of a transaction is 71:472. Figure 1 plots the number of frequent itemsets as a function of the support threshold, while Figure 2 shows a bitmap representing the horizontal dataset, where items were sorted by their frequency. Note that to reduce the siz...

This article focuses on the impact on learning processes when digital technologies are integrated into PBL (problem-based learning) oriented distance training. Based on socio-cultural perspectives on learning and a comparative distance-campus as well as a time-perspective, instructor and student roles, and learning activities were explored. Interviews with instructors and students were collecte...

This paper uses an innovative analysis of an individual‟s cognitive processes to investigate a real-life example of processing rendered subconcious by a mask that shared characteristics with the varied feature. In about half the participants, integrative performance on the object was better than analytical performance on the feature. The cognitive processes mediating this achievement varied amo...
