In this article we will present the concept of internet system structure supporting process of decision making steps for university candidates. The system will become an integral part of the Electronic System of Recruitment, which has been running at the University of Lodz for the last 4 years. In this article we will think of criteria and features that need to be used as the background for the conclusion as well as decision of choice for the system structure based on fuzzy logic. © 2009 IADIS.

Direct Evidence of a Nonorthogonal Magnetization Configuration in Single Crystalline Fe1−xCox/Rh/Fe/Rh(001) System

Tetragonal distortion in Fe1−xCox alloy films grown epitaxially on Rh(001) substrates results in a strong perpendicular magnetic anisotropy. Since the perpendicular magnetic anisotropy varies with the Fe1−xCox film composition, one can grow multilayer structures with ferromagnetic films sequentially showing either an in-plane (e.g., Fe) or out-of-plane (e.g., Fe0.5Co0.5) easy-magnetization axis. The Rh spacers mediate an interlayer coupling which couples the magnetizations either ferromagnetically or antiferromagnetically, depending on the spacer thickness. When the anisotropy energy is compatible to the coupling, it produces nonorthogonal magnetization configurations which vary under a small change of the external magnetic field.

Pd Atomic Chain Formation as a Result of Submonolayer Deposition of 3d Metals on Pd(110)

引用

Physical Review Letters 2009年第22期103卷 225504-225504页

作者： D. H. Wei C. L. Gao Kh. Zakeri M. Przybylski Max-Planck-Institut für Mikrostrukturphysik Weinberg 2 06120 Halle Germany and Faculty of Physics and Applied Computer Science AGH University of Science and Technology Mickiewicza 30 30-059 Kraków Poland

Submonolayer deposition of 3d transition metals such as Cr, Mn, Fe, Co, and Ni on Pd(110) at room temperature causes the formation of monoatomic chains of Pd as identified with scanning tunneling microscopy and spectroscopy. In agreement with recent theoretical predictions [Phys. Rev. B 79, 155410 (2009)], the substitution of Pd substrate atoms with the deposited atoms of 3d metals is found to be responsible for the formation of Pd atomic chains. This finding clarifies the long-debated issue about the chemical composition of the atomic chains grown on Pd(110) and points out the intriguing processes in the formation of self-assembled and self-organized nanostructures.

Thin Film on ASIC (TFA) technology combines advantages of two commonly used pixel imaging detectors, namely, Monolithic Active Pixels (MAPs) and Hybrid Pixel detectors. Thanks to direct deposition of a hydrogenated amorphous silicon (a-Si:H) sensor film on top of the readout ASIC, TFA shows the similarity to MAP imagers, allowing, however, more sophisticated front-end circuitry to extract the signals, like in case of Hybrid Pixel technology. In this paper we present preliminary experimental results of TFA structures, obtained with 10 · thick hydrogenated amorphous silicon sensors, deposited directly on top of integrated circuit optimized for tracking applications at linear collider experiments. The signal charges delivered by such a-Si:H n-i-p diode are small;about 37 e-/·· for minimum ionizing particles, therefore a low noise, high gain and very low power of the front- end are of primary importance. The developed demonstrator chip, designed in 250 ·· CMOS technology, comprises an array of 64 by 64 pixels laid out in 40 ·· by 40 ·· pitch.

We present the design and performance of the ABCN-25 readout chip implemented in 0.25 ¿m CMOS technology. The front-end design has been optimized for the short, 2.5 cm, silicon strips foreseen in the upgrade of the ATLAS Inner Detector. The core of the readout architecture includes binary front-end, two levels of data buffering, data compression and data serializing circuitry, and is similar to the architecture of the ABCD3T chip used in the present ATLAS SCT detector. In order to ensure required radiation hardness the hardening by layout technique has been used and SEU detection and correction circuitry have been added. The design includes on-chip power management circuitry comprising two types of shunt regulators and a serial regulator. This circuitry makes the ABCN-25 chip compatible with recent developments in the area of power distribution systems for the inner trackers in the SuperLHC environment and in particular with serial powering of the detector modules. The chip has been fabricated in 0.25 ¿m CMOS technology and full functionality has been obtained. The critical design aspects and performance of the analog and digital circuits will be presented and discussed.

Magnetic-Field Asymmetry of Electron Wave Packet Transmission in Bent Channels Capacitively Coupled to a Metal Gate

引用

Physical Review Letters 2009年第6期102卷 066807-066807页

作者： R. Kalina B. Szafran S. Bednarek F. M. Peeters Faculty of Physics and Applied Computer Science AGH University of Science and Technology al. Mickiewicza 30 30-059 Kraków Poland Departement Fysica Universiteit Antwerpen Groenenborgerlaan 171 B-2020 Antwerpen Belgium

We study the electron wave packet moving through a bent channel. We demonstrate that the packet transmission probability becomes an asymmetric function of the magnetic field when the electron packet is capacitively coupled to a metal plate. The coupling occurs through a nonlinear potential which translates a different kinetics of the transport for opposite magnetic-field orientations into a different potential felt by the scattered electron.

This paper presents a method for recognizing Bengali printed characters by using view-based and layer-based approaches. Two different view-based approaches, the top-bottom and the left-right have been used. The layer-based approach is also considered here. No thinning or segmentation is required. The individual character is taken as a whole image. The characteristic points are extracted from the views after some preprocessing. These points are then used to form a feature vector which represents the given character. These feature vectors are classified with the aid of dynamic time warping distance, k-NN and ensemble of classifiers. The concept can also be extended for Bengali word recognition.

This work reports application of core-shell nanoparticles in photovoltaic cells. These nanoparticles were fabricated form silicon carbide core covered with conductive form of polyaniline. The nanoparticles were dispersed in the active layer of the cell. It was found that this modification raised quantum efficiency of the photovoltaic cell by factor of three in comparison to a test cell without nanoparticles.
