Information seekers using the usual search techniques and engines are delighted by the sheer power of the technology at their command – speed, quantity. Upon closer inspection of the results, and reflection upon the next stages of the information seeking knowledge work, users are typically overwhelmed, and frustrated. We propose a partial solution by focusing on the query formulation aspect of ...

In this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. For these types of systems avoiding failure during the actual operation of the system is extremely important. In this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...

This paper is an extension of our previous work on the image segmentation of electronic structures on patterned wafers to improve the defect detection process on optical inspection tools. Die-to-die wafer inspection is based upon the comparison of the same area on two neighborhood dies. The dissimilarities between the images are a result of defects in this area of one of the die. The noise leve...

Visual secret checking refers to the superimposition of one key image and another public sharing image without auxiliary automated computation, in order to recognize the specified secret via human inspection. This paper achieves the goals of: guaranteeing that the related contents of a secret are not revealed after any public sharing image superimposition, confirming the accuracy of any public ...

Security in Java depends on an access control mechanism specified operationally in terms of run-time stack inspection. We give a denotational semantics in “eager” form, and show that it is equivalent to the “lazy” semantics using stack inspection. We give a static analysis of safety, i.e., the absence of security errors, that is significantly simpler than previous proposals. We identify several...

Glass defects which result into poor quality are a major reason of embarrassment for manufacturers. Glass defects are typically unavoidable, but their occurrence must be minimized during the production of highquality glasses. It is a tedious process to manually inspect very large size glasses. The manual inspection process is slow, time-consuming and prone to human error. Automatic inspection s...

To mitigate the threat that terrorists smuggle weapons of mass destruction (WMD) into the US through maritime containers, the US Bureau of Customs and Border Protection (CBP) inspects containers upon entry to domestic ports. Inspection-driven congestion is costly, and CBP provides incentives to firms to improve security upstream in the supply chain, thereby reducing the inspection burden at US ...

Syndromic surveillance (SyS) systems currently exploit various sources of health-related data, most of which are collected for purposes other than surveillance (e.g. economic). Several European SyS systems use data collected during meat inspection for syndromic surveillance of animal health, as some diseases may be more easily detected post-mortem than at their point of origin or during the ant...

Abstract The purpose of the research is to study the effect of wavelet-based denoising (WBD) technique in radar signal processing. In this paper, Block thresholding is used for WBD and its performance is compared with general MTI filter by simulation and experimental results. The comparisons which are based upon ROC and visual inspection of the resulting signals are accomplished for different D...
