pulse echo b - scan imaging systems have been used for years in medical diagnosis. the theroy of such systems have been investigated by several researchers. in this paper, we introduce a new model for b - scan imaging system based on gaussian type transducer. an imaging system is normally identified by its point response function. this function describes the image of a single physical point obj...

We present an architectural framework for systematically using automated diversity to provide high assurance detection and disruption for large classes of attacks. The framework executes a set of automatically diversified variants on the same inputs, and monitors their behavior to detect divergences. The benefit of this approach is that it requires an attacker to simultaneously compromise all s...

I very much enjoyed reading this paper. The basic message that I took away was that by and large different banks rate a given borrower in pretty much the same way. While we do see differences, on the whole at least to my eye these differences are generally small. I therefore read the paper as basically good news for the New Basel Capital Accord. If we want to worry about any of the results in t...

It is an accepted fact of academic life that some papers, in whatever discipline and wherever published, will never be cited. Empirical support for this can be found in studies such as those reported by Glanzel (1992), Rousseau (1994), and Egghe (2000) where the distribution of the time of first citation is investigated. In all cases, it is assumed that never-citation is connected with the perc...

Idioms are a big part of languages but can cause trouble for communication, especially for non-native speakers of a language. Interpreting idioms correctly means that one must derive a figurative meaning from words that individually mean something else. Recent research primarily focuses on the impact of context for successful idiom comprehension and seems to prioritize native speakers’ understa...

Lygus lineolaris (Palisot de Beauvois), Lygus hesperus (Knight) and Lygus rugulipennis (Poppius) can cause multiple-leaders to form on conifer seedlings. Injury due to Lygus bugs has increased during the last two decades to the point where these bugs are now considered the worst insect pest at many conifer nurseries. At several nurseries, Lygus bugs have injured 30% or more of the seedlings. Su...

As Field-Programmable Gate Array (FPGA) power consumption continues to increase, lower power FPGA circuitry, architectures, and Computer-Aided Design (CAD) tools need to be developed. Before designing low-power FPGA circuitry, architectures, or CAD tools, we must first determine where the biggest savings (in terms of energy dissipation) are to be made and whether these savings are cumulative. I...

artificial intelligence (ai) techniques offer powerful objective algorithms foranalysis of multimodal and high-dimensional data. recently, these techniques havebecome a reliable tool in the medical domain. this paper describes an efficienttechnique for building an application that is capable of forecasting and classifyinghealthcare information using machine learning as a subfield of ai methods....
