The current image retrieval systems are successful in retrieving images, using keyword based approaches. However, they are incapable to retrieve the images which are context sensitive and annotated inappropriately. Content-Based Image Retrieval (CBIR) aims at developing techniques that support effective searching and browsing of large image repositories, based on automatically derived image fea...

Finding information and preserving confidentiality are in some sense opposite goals, but there are a number of practical situations in which a balance must be struck between the two. Identifying relevant evidence in large collections of digital business records, the so-called “e-discovery” problem, is one such situation. Present practice involves consultation between attorneys representing plai...

Many of the available image databases have keyword annotations associated with the images. In spite of the availability of good quality low-level visual features that reflect well the physical content, image retrieval based on visual features alone is subject to semantic gap. Text annotations are related to image context or semantic interpretation of the visual content and are not necessarely d...

This paper reports our experimental investigation into the use of a reinforcement learning strategy to learn weights of (formal) concepts and keywords to support Information Retrieval. This work is a part of our main research objective of using more elegant construct of a concept rather than simple keywords as the basic element of representation and matching. The framework used for achieving th...

With the trend of lighter vehicle and more powerful engine (power plant) passengers are subjected to large vibration and harshness coming from the engine through the chassis. This paper discusses the application of active vibration control to reduce this vibration effect. Using a mass-spring-damper model which represents a passive engine mount, dynamic characteristic of the mount is obtained fo...

Significant parts of cultural heritage are produced on the web during the last decades. While easy accessibility to the current web is a good baseline, optimal access to the past web faces several challenges. This includes dealing with large-scale web archive collections and lacking of usage logs that contain implicit human feedback most relevant for today’s web search. In this paper, we propos...

We propose a model with heterogeneous interacting traders which can explain some of the stylized facts of stock market returns A generalized version of the Random Field Ising Model RFIM is introduced to describe trading behavior Imitation e ects which induce agents to trade can generate avalanches in trading volume and large gaps in demand and supply A trade friction is introduced which by resp...

abstractalthough the biokinetics, metabolism, and chemical toxicity of uranium are well known, until recently little attention was paid to the potential toxic effects of uranium on reproduction and development in mammals. in recent years, it has been shown that uranium is a developmental toxicant when given orally or subcutaneously (sc) to mice. decreased fertility, embryo/fetal toxicity includ...
