This paper presents an analyze of a learning organizational memory and some disadvantages that such a centralized application contains. One issue is the reuse of a prototype giving access to learning resources, outside the university where it was created, by teachers of the same domain, even if they are very interested to do so. One attempt for resolving this problem is to integrate distributed...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

Reinforcement grades higher than 75 ksi (520 MPa) are not allowed in members that form plastic hinges due to a lack of information on material characteristics and on the seismic performance of columns constructed with high-strength steel (HSS) reinforcement. This research investigated the performance of reinforced concrete columns containing Grade 80 (minimum yield strength of 80 ksi [550 MPa])...

Variable reinforcement schedules are used to arrange the availability of reinforcement following varying response ratios or intervals of time. Random reinforcement schedules are subtypes of variable reinforcement schedules that can be used to arrange the availability of reinforcement at a constant probability across number of responses or time. Generating schedule values for variable and random...

Advances in web technology have considerably widened the Web accessibility divide between sighted and blind users. This divide is especially acute when conducting online transactions, e.g., shopping, paying bills, making travel plans, etc. Such transactions span multiple web pages and require that users find clickable objects (e.g., “add-to-cart” button) which are essential for transaction prog...

The objective of this investigation is to develop an economical and efficient reinforcement scheme for large web openings in cold-formed steel (CFS) joists flexural zones that would restore the original moment resistance section. This considered commonly used floor North American CFS construction. Tests on webs with no circular square located at mid-depth revealed may reduce strength by 23%. A ...

search pointers organize the main part of the application on the internet. however, because of information management hardware, high volume of data and word similarities in different fields the most answers to the user s’ questions aren`t correct. so the web graph clustering and cluster placement in corresponding answers helps user to achieve his or her intended results. community (web communit...

The widespread diffusion of mobile phones is triggering an exponential growth of mobile data traffic that is likely to cause, in the near future, considerable traffic overload issues even in last-generation cellular networks. Offloading part of the traffic to other networks is considered a very promising approach and, in particular, in this paper we consider offloading through opportunistic net...

We put forward a modeling and algorithmic framework to design and optimize mechanisms in dynamic industrial environments where a designer can make use of the data generated in the process to automatically improve future design. Our solution, coined reinforcement mechanism design, is rooted in game theory but incorporates recent AI techniques to get rid of nonrealistic modeling assumptions and t...

Multi-label learning deals with ambiguous examples each may belong to several concept classes simultaneously. In this learning framework, the inherent ambiguity of each example is explicitly expressed in the output space by being associated with multiple class labels. While on the other hand, its ambiguity is only implicitly encoded in the input space by being represented by only a single insta...
