Safe and effective manipulation of soft tissue during laparoscopic and other minimal access surgical (MAS) procedures can be enabled by use of electromagnetic force. We investigated magnet interaction force using finite element modeling (FEM) and tensiometer measurement, and found that our FEM results were in good agreement with measurement data. Then, we describe a novel method of ferro-magnetisation...
The method that fin stabilizer is used to anti rolling ship is different from the conventional theory of anti rolling ship, so it is a kind of new theoretics. In order to study the process of lift generation of fin stabilizer at zero speed, the model of lift generation of fin stabilizer is built based on biomimetic theory such as Weis-Fogh mechanism with variable chord wings by the conformal representation...
The fin stabilizer is used to reduce the roll motion of ship at zero speed, which is a new application of fin stabilizer. In order to study the process of lift generation of fin stabilizer at zero speed, the model of lift generation of fin stabilizer with double variable chord wings is built based on biomimetic theory such as Weis-Fogh mechanism by the conformal representation. By the methods of simulation...
This paper describes about research on fluid analysis simulator for elastic oscillating fin of biomimetic underwater robots. Authors has been researching biomimetic underwater vehicle such as flapping wing type. In such system, new concept of fluid analysis simulator is required because of the unique fluid characteristics of elastic oscillating fin. First of all, this paper shows basic characteristics...
Ship biomimetic fins stabilizer is a kind of anti rolling ship technique that could produce lift with initiative swing of fins at zero forward speed, and the lift could counteract the rolling forces of ocean waves, which is a new application of fin stabilizer. In order to study the principle of lift generation of fin stabilizer at zero speed, seeked a kind of bionic theory to research the lift generation...
In this paper, a first prototype of a multifunctional tactile sensor using ionic polymer metal composites (IPMCs) is proposed, designed, and tested. Two IPMC strips are used, one as an actuator and one as a sensor, both positioned in a cantilever configuration; working together they enable the system to detect the presence of a material in contact with it and to measure its stiffness. These sensing...
This paper gives a review of acoustic and ultrasonic optical fiber sensors (OFSs). The review covers optical fiber sensing methods for detecting dynamic strain signals, including general sound and acoustic signals, high-frequency signals, i.e., ultrasonic/ultrasound, and other signals such as acoustic emissions, and impact induced dynamic strain. Several optical fiber sensing methods are included,...
Two complementary but equivalent semantic interpretations of a high level probabilistic programming language are given. One of these interprets programs as partial measurable functions on a measurable space. The other interprets programs as continuous linear operators on a Banach space of measures. It is shown how the ordered domains of Scott and others are embedded naturally into these spaces. Two...
