This paper presents the results of a series of small-scale model tests and numerical analyses conducted on circular and ring model footings located near geogrid reinforced sand slopes. Layers of geogrid were used as reinforcement. For numerical analyses Finite Element Method (FEM) was used. The effects of reinforcement depth, size, number of layers, and the horizontal distance between reinforce...

In this chapter, we discuss how ontologies can be constructed by extracting information from Web documents. This is a challenging task, because information extraction is usually a noisy endeavor, whereas ontologies usually require clean and crisp data. This means that the extracted information has to be cleaned, disambiguated, and made logically consistent to some degree. We will discuss three ...

Web engineering becomes increasingly important in the last years. WEB and audio services have to provide the best services possible. To achieve this goal, they have to find out what the customers are doing without altering their privacy. This paper presents two classes of models, mathematical and learning models, and two possible ways to manage and build adaptative menus. These methods are grav...

We now begin our study of reinforcement learning and adaptive control. In supervised learning, we saw algorithms that tried to make their outputs mimic the labels y given in the training set. In that setting, the labels gave an unambiguous “right answer” for each of the inputs x. In contrast, for many sequential decision making and control problems, it is very difficult to provide this type of ...

Interruption management has received a good deal of attention from researchers, but this work has not had a substantial impact on real-world applications. This paper examines the factors associated with interruption management in web-based systems (a highly restricted class of environments) and presents an adaptive interruption management system, Interrupt-Broker, as a component of a web-based ...

In this paper the design and implementation of an automatic web-based framework, is shown. A template has been implemented using XML and JavaScript. The instantiation of this framework turn out different activities. The mains properties of this template are three: a) the result can be executed on web navigator; b) the programation is transparent to user. Only, the user has to fill the template ...

quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

Herein we build statistical foundations for tackling the navigation problem users encounter during web interaction, based on a formal model of the web in terms of a probabilistic automaton, which can also be viewed as a finite ergodic Markov chain. In our model of the web the probabilities attached to state transitions have two interpretations, namely, they can denote the proportion of times a ...

In this paper, we present an approach and a visual tool, called HWrap (Handle Based Wrapper), for creating web wrappers to extract data records from web pages. In our approach, we mainly rely on the visible page content to identify data regions on a web page. In our extraction algorithm, we inspired by the way a human user scans the page content for specific data. In particular, we use text fea...
