In the field of production, characterization of surface roughness plays a vital role in assessing the quality of a manufactured product. The defined parameters for this assessment, each, have their own drawbacks in describing a profile surface. From the purview of small-scale and medium-scale industries, an increase in time spent for manual inspection of a product for various parameters adds to...

At first glance, shot profile migration and source-receiver (survey-sinking) migration seem to be substantially different algorithms. The basic principles used by the two schemes are different. Shot profile migration is performed by independently propagating the source wavefield and the receiver wavefield. The image is obtained by cross-correlating (possibly normalized by the amplitude of the s...

In this report, we present details about the participation of WHUSUM in the guided summarization track at TAC 2011. Guided summarization task requires participants to produce short, coherent summaries of news articles with the guidance of predefined categories and aspects for each category. This year, we extended our query-focused update summarization system with aspect related information. In ...

This note discusses the estimation of systematic uncertainties and their incorporation into upper limit calculations. Two different approaches to reducing systematics and their degrading impact on upper limits are introduced. An improved χ function is defined which is useful in comparing Poisson distributed data with models marginalized by systematic uncertainties. Also, a technique using profi...

Although Web technology is widely used in today’s classrooms, educationists are still unsure of its capability to generate meaningful learning. As the numbers of web-based learning (WBL) materials keep increasing tremendously, more students will rely on such resources in their learning process. WBL is always seen as a platform to deliver information, and as such, most of its learning materials ...

We investigate the structure of model selection problems via the bias/variance decomposition. In particular, we characterize the essential aspects of a model selection task by the bias and variance profiles it generates over the sequence of hypothesis classes. With this view, we develop a new understanding of complexity-penalization methods: First, the penalty terms can be interpreted as postul...

Trajectories have been providing us with a wealth of derived information such as traffic conditions and road network updates. This work focuses on deriving user profiles through spatiotemporal analysis of trajectory data to provide insight into the quality of information provided by users. The presented behavior profiling method assesses user participation characteristics in a treasurehunt type...

In this research work, first, based on the three-dimensional elasticity theory and by means of the Generalized Differential Quadrature Method (GDQM), free vibration characteristics of functionally graded (FG) rectangular plates resting on Pasternak foundation are focused. The two-constituent functionally graded plate consists of ceramic and metal grading through the thickness. A three-parameter...

The guided summarization aims to capture evolving information of a single topic changing over time under the background of much emergency happenings. It delivers salient and novel information to a user who has already read a set of older documents covering the same topic. Topic is category oriented, however, there is no query description. Therefore, guided summarization raises new challenges. I...
