This paper addresses a target detection problem for which the covariance matrix of the unknown Gaussian clutter background has block diagonal structure This block diagonal structure is the consequence of the target lying along a boundary between two statistically independent clutter regions Here we design adaptive detection algorithmsusing both the generalized likelihood ratio GLR and invarianc...

Muscular bridge (MB) is transient systolic coronary blockage occurring due to exposure of a portion of epicardial coronary arteries to compression during systole as a result of tunneling into the myocardium. Although rare, these patients may develop angina pectoris, severe arrhythmia and myocardial infraction (MI). A 30-year-old male patient presented to the emergency with severe pain with an o...

When images compressed with block-based compression techniques are transmitted over a noisy channel, unexpected block losses occur. Conventional methods that do not consider edge directions can cause blocked blurring artifacts. In this paper, we present a post-processing-based block recovery scheme using Haar wavelet features. The adaptive selection of neighboring blocks is performed based on t...

in this paper we study the module contractibility ofbanach algebras and characterize them in terms the conceptssplitting and admissibility of short exact sequences. also weinvestigate module contractibility of banach algebras with theconcept of the module diagonal.

introduction: we previously shown that microinjection of glutamate into the hdb of rat elicited cardiovascular depressive responses. microinjection of ap5 (an nmda receptor antagonist, 2.5 mm, 50 nl) and cnqx (an ampa receptor antagonist, 1 mm, 50 nl) caused no significant changes in the blood pressure and heart rate. microinjection of bicuculline (bmi: a gabaa receptor antagonist, 1 mm, 50 nl)...

Intercoronary communication is a very rare coronary artery anomaly. It is defined as an open-ended circulation with bidirectional blood flow between two coronary arteries. Coronary artery fistulas are abnormal communications between a coronary artery and a cardiac chamber or major vessel. A 62-year-old man was admitted to our hospital with sudden development of general weakness, dizziness and a...

The H. 264/AVC offer many coding tools that give higher compression ratio compared to earlier standards. These tools increase the computational complexity of the motion estimation. In this paper, we have presented a computationally efficient method to speed up the search process by minimizing the computational load on general full search. The proposed method is having two phases, wherein the fi...

In recent years special attention has been devoted to the problem of finding a copula, the diagonal section and opposite diagonal section of which are known. For given diagonal function and opposite diagonal functions, we provide necessary and sufficient conditions for the existence of a copula to have these functions as diagonal and opposite diagonal sections. We make use of techniques related...

Online detection of hydrodynamics of gas-solid fluidized bed was characterized using pressure fluctuations by cross recurrence plot (CRP) and cross recurrence quantification analysis (CRQA). Experiments were conducted in a lab scale fluidized bed of various particle sizes 150 μm, 280 μm and 490 μm at different gas velocities. Firstly, pattern changes of cross recurrence plot were discussed and ...
