INTRODUCTION The present study compares human landing catches of primary malaria vectors with two alternative methods of capture: the Shannon trap and the Mosquito magnet. METHODS This study used regression models to adjust capture data to a negative binominal distribution. RESULTS Capture numbers and relative percentages obtained from the three methods vary strongly between species. The hi...
The KSTAR device is a tokamak with a fully superconducting (SC) magnet system, which enables an advanced quasi-steady-state operation. Initial operation of the KSTAR SC magnet system has been accomplished for the first plasma discharge operation. The SC magnet system consists of 16 toroidal field (TF) coils and 14 PF coils, magnetic structures, SC buslines, current leads, and monitoring and pro...
An analytical technique is developed for predicting the performance of a bonded Halbach oriented anisotropic magnet, with due account of partial alignment of the NdFeB powder during injection molding. The predicted performance of a 12-pole injection molded, Halbach oriented magnet is compared with measurement.
Canada's largest magnet, which is now making functional magnetic resonance imaging possible at Ontario's Robarts Research Centre, is expected to cast some light on mysteries buried within the brain. With the huge magnet, said Dr. Ravi Menon, "I can distinguish between centres that control the thumb and the index finger."
This paper is devoted to the numerical modeling and simulation of hydrodynamic and dissipation processes in damper systems, where the working element is a magnetic fluid drop around a permanent magnet. Flow patterns and dimensionless dissipation coefficient depending on the Reynolds number and magnet position are established. r 2004 Elsevier B.V. All rights reserved. PACS: 02.60.Cb; 02.70.Dh; 4...
A mononuclear Er(III) sandwich type complex, [Li(DME)3][Er(III)(COT")2], was isolated using 1,4-bis(trimethylsilyl)cyclooctatetraenyl dianion (COT"). Remarkably, this low-symmetry complex exhibits magnet-like behavior of magnetic remanence and coercivity in the hysteresis loops up to 8 K with an energy barrier (Ueff) of 187(1) K, thus making this molecule a unique single-ion magnet.
We present Magnet Mail (MM), a visualization system to retrieve information from email archives via a zoomable interface. MM allows users to infer relationships among their email documents based on searching keywords. The prototype interacts with a mass-market email system and uses a magnet metaphor to simulate user interaction with emails. The graphical implementation relies mostly on the Picc...
This paper proposes collision-free structure using NdFeB thin-film magnet for vibration energy harvesters. By using stripe shaped NdFeB magnet array on the Si MEMS structure, we finally obtained 3 mN of magnetic repulsive force on 8 × 8 mm specimen with 40 μm air-gap.
Received: 2 November 2004 Revised: 5 April 2005 Accepted: 11 April 2005 Abstract The use of multivariate information visualization techniques is intrinsically difficult because the multidimensional nature of data cannot be effectively presented and understood on real-world displays, which have limited dimensionalities. However, the necessity to use these techniques in daily life is increasing a...
