Manual analysis of pedestrians and crowds is often impractical for massive datasets of surveillance videos. Automatic tracking of humans is one of the essential abilities for computerized analysis of such videos. In this keynote paper, we present two state of the art methods for automatic pedestrian tracking in videos with low and high crowd density. For videos with low density, first we detect...

1. BACKGROUND The state of warfare over the past several decades has rapidly evolved, requiring an equally agile adaptation by Army forces. Two decades previous, threats to our nation came from superpower struggles initiated by large adversarial nations such as The Soviet Union. Today, emerging dominant nations and aggressive meta-national entities based within failing states are the greatest m...

BACKGROUND AND PURPOSE Cerebrovascular reactivity (CVR), measures the ability of the cerebrovasculature to respond to vasoactive stimuli such as CO2. CVR is often expressed as the ratio of cerebral blood flow change to CO2 change. We examine several factors affecting this measurement: blood pressure, stimulus pattern, response analysis and subject position. METHODS Step and ramp increases in ...

INTRODUCTION We assessed the effect of different positions of voiding on uroflowmetry findings in healthy men and in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS Ten men with symptomatic BPH and 10 healthy men were enrolled in this study. Urodynamic study was done for each subject in 3 positions: standing, crouching (the position used in the Iranian style toilets), ...

Software Defined Network interoperate with other technologies like flow visor and open flow. This enables slicing of the network in many ways, including MAC, IP and VLAN. It also enables seamless interconnections with multiple controllers, providing the ability to run multiple applications each on a different controller. The purpose of this interoperability analysis is to test the applications ...

  Uncertainty plays a major role in any project evaluation and management process. One of the trickiest parts of any production project work is its cost and time forecasting. Since in the initial phases of production projects uncertainty is at its highest level, a reliable method of project scheduling and cash flow generation is vital to help the managers reach successful implementation of the ...

A large diversity of fishes struggle early in life to forage on zooplankton while under the threat of predation. Some species, such as zebrafish (Danio rerio), acquire an ability to forage in the dark during growth as larvae, but it is unclear how this is achieved. We investigated the functional basis of this foraging by video-recording larval and juvenile zebrafish as they preyed on zooplankto...

In this paper, the absorbent carryover effect in a designed counter-flow enthalpy exchanger is investigated. In a built prototype of the liquid desiccant dehumidifier, air and the absorbent solution are in contact and flow through a packed multi-channel polymer tower in a counter-flow pattern. To avoid the absorbent carryover, the tower is equipped with an eliminator. Experimental measurements ...

Local scouring around bridge piers is a natural phenomenon caused by the erosive process of flowing stream on alluvial beds. The 3D flow field around bridge piers interacting with the bed materials increases complexity of local scour process. The local scour depth develops in accelerated flows and if it is not predicted correctly, the bottom level of local scour hole will exceed the original le...
