this paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of iranian standard 2800. seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. these models cover a wide range of very torsional...

IN THE study of the APRL-Sierra No. 1 right hand, which preceded that of the left, the results of comparative performance testing indicated that there was little difference between the hand and the hook on the various test activities. Statements of children participating in the study—and of their parents—indicated a relatively high level of performance with the experimental hand, but advantages...

Trait anxiety is a personality characteristic that describes the tendency to feel anxious across a variety of situations, while state anxiety refers to the anxiety experienced in a specific situation (Cox, 2007). Previous research has suggested that high trait anxious individuals experience more situation-specific state anxiety (Horikawa & Yagi, 2012). Additionally, prior research has indicated...

In this policy brief we argue that there is little debate about the statistical properties of value-added model (VAM) estimates of teacher performance, yet, despite this, there is little consensus about what the evidence about VAMs implies for their practical utility as part of high-stakes performance evaluation systems. A review of the evidence base that underlies the debate over VAM measures,...

This work presents two main contributions to achieve robust multiple-target tracking in uncontrolled scenarios. A novel system which consists on a hierarchical architecture is proposed. Each level is devoted to one of the main tracking functionalities: target detection, low-level tracking, and high-level tasks such as target-appearance representation, or event management. Secondly, tracking per...

This report was written in order to complete the requirements for my Master's degree, under supervision of prof. In this report, an introspective machine, capable to pass judgement on its own deductive performances, is modelled and analyzed. First, the class of ideal machines which is provided with unlimited resources is studied. Since ideal introspective machines are usually unfeasible, their ...

Most concept recognition in visual multimedia is based on relatively simple concepts, things which are present in the image or video. These usually correspond to objects which can be identified in images or individual frames. Yet there is also a need to recognise semantic concepts which have a temporal aspect corresponding to activities or complex events. These require some form of time series ...

A well known and still open issue for wireless ad hoc networks is the unfair energy consumption among the nodes. The specific position of certain nodes composing an ad hoc network makes them more involved in network operations than others, causing a faster drain of their energy. To better distribute the energy level and increase the lifetime of the whole network, we propose to periodically forc...
