We present thermoelectric measurements of the heat dissipated due to ferromagnetic resonance of a Permalloy strip. A microwave magnetic field, produced by an on-chip coplanar strip waveguide, is used to drive the magnetization precession. The generated heat is detected via Seebeck measurements on a thermocouple connected to the ferromagnet. The observed resonance peak shape is in agreement with...

The survival probability of a particle diffusing in the two-dimensional domain x > 0 near a "windy cliff" at x = 0 is investigated. The particle dies upon reaching the edge of the cliff: In addition to diffusion, the particle is influenced by a steady "wind shear" with velocity v(x,y)=vsign (y)~, i.e., no average bias either toward or away from the cliff. For this semi-infinite system, the part...

Given a finite set of spheres of different sizes we study the three-dimensional Strip Packing Problem (3D-SPP) as well as the three-dimensional Knapsack Problem (3D-KP). The 3D-SPP asks for a placement of all spheres within a cuboidal strip of fixed width and height so that the variable length of the cuboidal strip is minimized. The 3D-KP requires packing of a subset of the spheres in a given c...

Abstract The proposed method focuses on the interaction of global and local buckling. A modified Ayrton‐Perry type buckling curve is to calculate ultimate compression force resistance centrically compressed cold‐formed C channel. new incorporates both effects imperfections shift center gravity caused by slender web plate considered sections. Distortional usually does not play any role for this ...

Finite-size scaling, finite-size corrections, and boundary effects for critical systems have attracted much attention in recent years. Here we derive exact finite-size corrections for the free energy F and the specific heat C of the critical ferromagnetic Ising model on the Mu x 2 Nu square lattice with Brascamp-Kunz (BK) boundary conditions [J. Math. Phys. 15, 66 (1974)] and compare such resul...

The cross-strip imaging readout employs charge division, and centroiding, of microchannel plate charge signals detected on two orthogonal layers of sense strips to encode event X-Y positions and times. We have developed cross-strip detectors and fully parallel channel position encoding electronics. The front-end amplifiers utilize two 32-channel pre-amplifier ASICs that send signals to a full 6...

In semiconductor packaging, warpage is one of the critical issues during molding stage. It is related to a thermal mismatch i.e. coefficient of thermal expansion (CTE) values and reliability of passive components in the package. Finite element method (FEM) is able to perform extensive structural analysis of quad flat no-lead (QFN) package designs once verified by experiments. 2 factorial is emp...

Flow features and forces of three-dimensional flapping foils are presented with aspect-ratio (AR) variations. The similitude rolling twisting kinematics is maintained across different ARs. An AR correction analogous to Prandtl finite-wing theory developed, enabling future use strip in the analysis design finite foils.

This paper proposes a POS aided LiDAR strip adjustment method. Firstly, aero-triangulation of the simultaneously obtained aerial images is conducted with a few photogrammetry-specific ground control points. Secondly, LiDAR intensity images are generated from the reflectance signals of laser foot points, and conjugate points are automatically matched between the LiDAR intensity image and the aer...

Background/Aims: Beta (β)thalassaemia is a public health problem in Malaysia. The carrier rate is estimated to be 4.5% by micro-mapping studies particularly among Malays who comprise 53.5% of the population in Malaysia (1). The common diagnostic method in Malaysia for mutation detection is by amplification refractory mutation system (ARMS). It allows single mutation detection in each reaction b...
