Kurzfassung. Der Einsatz von 3D-Ultraschall ist für zahlreiche medizinische Applikationen interessant. Ein 3D-Ultraschall Datensatz kann aus 2D-Schichtbildern rekonstruiert werden, wenn deren Positionen im Raum bekannt ist. Mittels eines Trackingsystems kann die Position eines Schallkopfes im Raum verfolgt werden. Die Beziehung von Bildebene und Schallkopf muss durch eine Kalibrierung bestimmt ...

this paper presents future trends of urban wastes and their impacts on the environment of african cities using plausible mitigation scenarios. to accomplish this, an integrated dynamic model for urban waste flows was developed, tested, calibrated and validated. its parameter sensitivity was analyzed. using population projection up to 2052 with different levels of technological implementation, p...

It is well known [4, p. 265; 3] that the space 7,i[0, l] is not isomorphic with a conjugate space. At the other extreme, it is also well known that h is isometric with the conjugate space of Co. Each of these is an example of a space of all real-valued integrable functions over a measure space (T, p), a major difference between them being that the measure space underlying 7_i[0, l] has no atoms...

Evolution Strategies (ES) are a class of Evolutionary Algorithms based on Gaussian mutation and deterministic selection. Gaussian mutation captures pair-wise dependencies between the variables through a covariance matrix. Covariance Matrix Adaptation (CMA) is a method to update this covariance matrix. In this paper, the CMA-ES, which has found many applications in solving continuous optimizatio...

In this paper, we propose an efficient approximated rank one update for covariance matrix adaptation evolution strategy (CMA-ES). It makes use of two evolution paths as simple as that of CMA-ES, while avoiding the computational matrix decomposition. We analyze the algorithms’ properties and behaviors. We experimentally study the proposed algorithm’s performances. It generally outperforms or per...

BACKGROUND Many strategies to control opisthorchiasis have been employed in Thailand, but not in the other neighbouring countries. Specific control methods include mass drug administration (MDA) and health education to reduce raw fish consumption. These control efforts have greatly shifted the epidemiology of Opisthorchis viverrini (OV) infection over the last decade from presenting as densely ...

Background: Transgenic mice are being considered as invaluable tool in biological sciences towards comprehension of the cause of the genetic diseases. Manipulated embryonic stem (ES) cells are used to produce loss-of-function mutant mice. Microinjection of manipulated ES cells into blastocoel cavity, and morula fusion are the two main techniques in producing transgenic mice. So...

Objective(s): Association of adolescent emotional stress (ES) with the incidence of cardiovascular disease (CVD) at older age was investigated. Materials and Methods: 21 female rats were divided into three groups of 7 each; ES, foot-shock, and control. Chronic ES was induced by exposing the rats to witness foot-shock of their neighboring...

Using an in vitro differentiation protocol we isolated cells with the properties of dendritic cells (DCs) from immunologically refractive pluripotent murine embryonic stem cells (ESCs). These ES-derived dendritic cells (ESDCs) expressed cytokines and were able to present antigen to a T cell line. Infection of ESDCs with Salmonella Typhimurium stimulated the expression of immune cell markers and...
