Curricular analytics is the area of learning that looks for insights and evidence on relationship between curricular elements degree achievement outcomes. For higher education institutions, can be useful identifying strengths weaknesses curricula justifying changes in pathways students. This work presents study trajectories as processes (i.e., sequence events) using process mining techniques. S...

Introduction: The carry of heavy backpacks by school children may be associated with several potential health consequences. The aim of this study was to determine the percentage of body weight represented by school backpacks and other related factors. Materials and Methods: The cross-sectional study has been done in eight primary schools in Yazd city in which a total of 783 students’ boys (217...

Berkeley proposed that space is perceived in terms of effort. Consistent with his proposal, the present studies show that perceived egocentric distance increases when people are encumbered by wearing a heavy backpack or have completed a visual-motor adaptation that reduces the anticipated optic flow coinciding with walking effort. In accord with Berkeley's proposal and Gibson's theory of afford...

This paper describes the use of parallel classifiers in real-time object recognition. Based on preliminary results we propose a mobile platform built with off-the-shelf components (hardware and software). This platform could be fitted in a robot, car, backpack etc. A model of the performance of the platform using the Viola-Jones detector is presented. Simulation results are presented based on p...

A backpack trip to Ice Lake (2435 m) and the summit of the Matterhorn (2995 m) in the Wallowa Mountains in Oregon sponsored by Northwest Lichenologists resulted in numerous interesting finds, including several rare species and new state records. Caloplaca oblongula, C. saxifragarum, Cephalophysis leucospila, Dermatocarpon polyphyllizum, Farnoldia micropsis, and Solorina spongiosa are apparently...

INTRODUCTION In occupational, military and recreational activities, loads are often carried in a backpack. Modern backpacks utilise a hip belt and shoulder straps to redistribute the load from the back to the large muscle groups surrounding the hips and legs in an attempt to protect the lower back from injury. However, by redistributing these loads the lower limbs are subjected to repetitive me...
