In this paper we present the parallel implementation of a common image processing operation: the low-pass filter (LPF). The parallel LPF was implemented using the message passing programming model in a cluster of workstations. Our main goal is to reduce the response time of the filtering operation yet maintaining the quality of the processed image. In order to achieve this goal we developed a p...

LISA, the Laser Interferometer Space Antenna, is a proposed ESA/NASA space based gravitational wave detector. In order to help meet the many technological challenges of LISA, the ESA precursor mission LISA Pathfinder (LPF) will test some of the key enabling technologies for LISA. LPF however will only go so far, and much work is needed to take LPF technology to a state suitable for LISA. One su...

We present experimental and finite-difference time-domain simulation studies on high pass filter (HPF) based on transverse electric (TE) mode, low pass filter based (LPF) on multiple slits, and tunable notch-filter based on single slit. The LPF and notch filter are carried out by using the metal slits positioned at the center of the air gaps in tapered parallel-plate waveguides (TPPWG).

A novel structure of dual-composite right/lefthanded transmission line (D-CRLH TL) is proposed and analyzed in this paper. The simulated results show that there is a stopband between the first right-handed passband and the left-handed passband of the proposed D-CRLH TL. This stopband characteristic is applied to improve the electromagnetic performances of low-pass filter (LPF). A planar compact...

The curing behavior of lignin-based phenol-formaldehyde (LPF) resin with different contents of nano-crystalline cellulose (NCC) was studied by differential scanning calorimetry (DSC) at different heating rates (5, 10 and 20 ̊C/min) and the bonding property was evaluated by the wet shear strength and wood failure of two-ply plywood panels after soaking in water (48 hours at room temperature and f...

Top-down control processes are critical to select goal-directed actions in flexible environments. In humans, these processes include two inhibitory mechanisms that operate during response selection: one is involved in solving a competition between different response options, the other ensures that a selected response is initiated in a timely manner. Here, we evaluated the role of dorsal premoto...

A model was developed for material deformation processes induced by laser-generated shock waves. The processes include laser peen forming LPF and laser shock peening LSP of metals. Numerical solutions of the model using finite element method were implemented in two steps: 1 explicit step, devoted to shock wave propagation, and 2 implicit step, calculating relaxation of material. A series of LPF...

This paper describes the theorem proving component of a larger software development environment for the ISO standardized spec-iication language VDM-SL. This component is constructed as an instan-tiation of the generic theorem prover Isabelle with a VDM-SL variant of the Logic of Partial Functions (LPF). We describe the development of this instantiation, focusing on both the embedding of syntax ...

objective: the aim of the this study was to investigate the prevalence of toxb, paa, lpf and iha adhesion genes in enteropathogenic escherichia coli (epec) isolates lacking in two important adhesion factors, the eaea and bfpa genes. methods: we examined a total of 70 serologically confirmed epec (eaea-, bfpa-) isolates. dna from the isolates was extracted by the phenol-chloroform method. toxb,...
