Change detection scheme based on guided contrasting was previously proposed. Guided contrasting filter takes two images (test and sample) as input and forms the output as filtered version of test image. Such filter preserves the similar details and smooths the nonsimilar details of test image with respect to sample image. Due to this the difference between test image and its filtered version (d...

Molecular diffusion in brain extracellular space (ECS) is primarily controlled by interactions with the geometry and the interstitial matrix. Both factors increase λ, the tortuosity, a measure of hindrance to diffusion where λ2 = D/D∗ with D the free diffusion coefficient and D∗ the effective diffusion coefficient in brain [1]. Geometry lengthens diffusion paths or creates holdup in local voids...

In this paper we will consider elliptic boundary value problems with oscillatory diffusion coefficient, say A. We will derive regularity estimates in Sobolev norms which are weighted by certain derivatives of A. The constants in the regularity estimates then turn out to be independent of the variations in A. These regularity results will be employed for the derivation of error estimates for hp-...

The rotating cone reactor is a novel reactor type for rapid thermal processing of solids. This paper focuses on the experimental determination of the gas-to-particle heat transfer coefficient. This quantity has been measured for several particle diameters (average size of 150, 280 and 425 pm) and cone rotational frequencies (11.3 and 28.3 Hz). The gas-to-particle heat transfer coefficient obtai...

Information technology as a more intermediary utilizes the science of the day to provide the necessary data for the specialists, organizations, and ultimately all types of groups in the shortest possible time and in the best possible way. Many countries believe that entrepreneurship has played an indispensable role in improving productivity and economic growth. Since the benefits of tourism ind...

In recent years several workers have published methods for accurately approximating a function with discontinuities, given Fourier coefficient information. Our own contribution concentrates on robustness and use of low order coefficients. In this paper we present a version of our method which is local in that it approximates the orthogonal projection of the function onto a space of splines whic...

BACKGROUND Cancer mortality is increasing with the aging of the population in Japan. Cancer information obtained through feasible methods is therefore becoming the basis for planning effective cancer control programs. There are three time-related factors affecting cancer mortality, of which the cohort effect is one. Past descriptive epidemiologic studies suggest that the cohort effect is not ne...
