BACKGROUND Implantation of testosterone pellets under the lateral abdominal wall skin is an old but popular and effective form of androgen replacement therapy. Extrusion of one or more pellets remains the most frequent adverse event. OBJECTIVE To determine whether an alternative implantation site (hip) and/or track geometry (two vs. four tracks) would reduce extrusion rates compared with the ...

This paper proposes a procedure for comparison of target tracking filters in cluttered environment, using simulated experiments. Important simulation issues, including track generation and retention across simulation runs and true track definition are discussed. False track discrimination is identified as an important target tracking filter performance measure. This measure has two components; ...

In order to track a maneuvering target, multiple model (MM) methods have been researched. Almost MM algorithms have been developed based on Markov process. However, Markov based MM method is difficult to design and application-dependent. To solve this problem, Daebum Choi, et al proposed basic idea of neural-net based VSMM [5]. In this paper, we will show the design procedure of neural-net base...

regarding increasing importance of tank wagons and efficiency in fluids transportation, their usage is increasing every day. thus paying attention to their designs just as dynamic analysis of wagons during travelling time is vitally important. in this task, sloshing coefficient as prominent parameter in tank wagons designing has been investigated. to ease of efficient design, theses parameters ...

This paper addresses the problem of designing guidance, control and navigation systems for autonomous underwater vehicles (AUVs). Its contribution is twofold: i) it introduces a new methodology for the integrated design of guidance and control, and ii) it describes a novel approach to the analysis and design of multi-rate complementary filters for navigation. The methodologies proposed lead to ...

car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. to do so, car body acceleration is determined using a 10 dof simulat...
