COMPUTATIONAL ASPECTS OF RADIATIVE TRANSFER EQUATION IN NON-ORTHOGONAL COORDINATES

Non-equilibrium energy transfer takes place for thin films when thermal disturbance is introduced. In this case, phonon transport inside the film governs the heat transport and temperature distribution in the film. In the present study an attempt is made to formulate and illustrate the phonon transfer in micro-scale silicon film of various shapes incorporating the non-orthogonal coordinate system. Successful application of the discrete-ordinates method to the solution of the equation for phonon radiative transport in non-orthogonal coordinates requires the application of various numerical techniques connected to the finite-difference method. The numerical solution of the equation for phonon transfer in non-orthogonal coordinate is introduced via adapting the discrete ordinate method. Phonon intensity distribution in the thin film is presented in terms of equivalent equilibrium temperature. It is found that film shape has significant effect on equivalent equilibrium temperature distribution inside the film. The validation study demonstrates that the code developed solving the equation for phonon transport is also applicable to the phonon transport in non-orthogonal coordinate system.

Finger Biometric Recognition With Feature Selection

Biometrics is indispensable in this modern digital era for secure automated human authentication in various fields of machine learning and pattern recognition. Hand geometry is a promising physiological biometric trait with ample deployed application areas for identity verification. Due to the intricate anatomic foundation of the thumb and substantial inter-finger posture variation, satisfactory performances cannot be achieved while the thumb is included in the contact-free environment. To overcome the hindrances associated with the thumb, four finger-based (excluding the thumb) biometric approaches have been devised. In this chapter, a four-finger based biometric method has been presented. Again, selection of salient features is essential to reduce the feature dimensionality by eliminating the insignificant features. Weights are assigned according to the discriminative efficiency of the features to emphasize on the essential features. Two different strategies namely, the global and local feature selection methods are adopted based on the adaptive forward-selection and backward-elimination (FoBa) algorithm. The identification performances are evaluated using the weighted k-nearest neighbor (wk-NN) and random forest (RF) classifiers. The experiments are conducted using the selected feature subsets over the 300 subjects of the Bosphorus hand database. The best identification accuracy of 98.67%, and equal error rate (EER) of 4.6% have been achieved using the subset of 25 features which are selected by the rank-based local FoBa algorithm.
Radiofrequency catheter ablation in atrial arrhythmias : insight into pre-procedural evaluation and procedural guidance

Radiofrequency catheter ablation (RFCA) has become an important treatment option in the management of supraventricular arrhythmias such as atrioventricular (nodal) re-entry tachycardia, atrial tachycardia, atrial flutter and atrial fibrillation (AF). Particularly in the management of AF the number of RFCA procedures performed is growing rapidly. Three-dimensional electroanatomical mapping combined with non-invasive imaging is currently a state of the art technique to guide RFCA for complex arrhythmias such as AF ablation, providing information on anatomical landmarks and arrhythmogenic substrate with higher accuracy and with less radiation exposure than fluoroscopy or conventional catheter based mapping. Importantly, accurate characterization of the arrhythmogenic substrate and the underlying mechanisms of the arrhythmia as well as visualization of anatomical landmarks are pivotal to optimize the results of RFCA. Comprehensive pre-procedural evaluation may help to identify the appropriate substrate as well as to identify patients with a high likelihood to benefit from a RFCA procedure.

First Year Students’ Perceptions in Transition to University: The Students’ Experience

Studies about the transition to university emphasise the importance of the process of adaptation in the first year as a determining persistence factor. This article presents the results of the focus groups held with students of two undergraduate degree programmes, Pedagogy and Business Management and Administration, at the Universityof Barcelona(Catalonia, Spain) that dealt with the more significant situations they experienced in the process of adapting to life at university. The results are based on the five main tasks in the process of transition to university: starting and developing new social relationships; adjusting expectations about the university and degree programme; adapting to new academic codes at university; coping with academic/exam results; and construction of the university identity. These five tasks are identified in three moments in the initial period of adaptation. This study forms part of a Research+Development project.
Small Evolution Antenna Design Method Based on Dynamic Hill Climbing Algorithm and Orthogonal Experiment

Small-scale evolution antennas have the advantages of high gain, wide bandwidth and small size, and have broad application prospects in the aerospace field. Aiming at the complex high-dimensional and dynamic problems of aerial antenna modeling, a dynamic hill-climbing algorithm based on orthogonal design is designed and implemented to simulate and optimize the single-span antenna in high-frequency operation mode. In the optimization problem, this paper defines a new individual comparison mechanism, which can reflect the number of violations of constraints and the degree of violation of each constraint, making the comparison of individuals more reasonable. The antenna simulation results demonstrate the effectiveness and feasibility of using dynamic evolutionary algorithms for antenna design.
Severity and Risk Factors of Post-Operative Pain in University of GondarHospital, Northeast Ethiopa

Background: Pain is a sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage according to Association of the Study of Pain. Despite advances in medical science inadequate post-operative pain management exists in Ethiopia and worldwide. Several perioperative and pre-clinical factors are recognized in contributing to enhancement of pain severity and its adverse effect. Objective: This study is aimed at assessing the severity and identifying the risk factors contributing to postoperative pain. Methodology: A hospital based cross sectional study was conducted on all patients who came to Gondar university hospital, Ethiopia operating theatre from March-of April 15, 2013. Data was collected by administering questionnaires via interview and reviewing the patients chart after taking consent. Numeric rating scale was used to assess pain severity. Logistic regression was used to identify independent risk factors for post-operative pain. Result: 150 patients are included in the prospective study. Moderate to severe pain was reported in 85(57%) of patients in the immediate post-operative period and 117(78%) in the 1st 12 hour. On multivariate analysis ASA I and II OR (4.0) P (0.013), age less than 60 OR (2.642) P (0.042), female gender with an OR (2.580) P (0.005), general anesthesia OR (5.562) P (0.000), and incision length >10cm OR (1.991) P (0.041) were identified as independent risk factors for post-operative pain severity. Conclusion: The study confirms that post-operative pain is still severe and under managed. Identifying perioperative factors for the occurrence of moderate/severe post-operative pain may be useful for designing factor specific interventions to relieve patient suffering.
Respiratory and skeletal muscles in chronic obstructive pulmonary disease

Summary Respiratory and peripheral muscles adapt to chronic obstructive pulmonary disease(COPD) differently, but remodelling also differs within the respiratory and theperipheral muscles. While the diaphragm adapts towards a slower proﬁle, peripheralmuscles adapt to COPD by shifting towards a faster proﬁle, as do the externalintercostal muscles. As a consequence, oxidative capacity is preserved in thediaphragm while being reduced in peripheral muscles. Due to hyperinﬂation,diaphragm force is reduced, although patients can generate higher maximalinspiratory pressures at a given lung volume than healthy subjects. Reduction inperipheral muscle force seems to be more severe for the lower- than the upper-limbmuscles. Peripheral muscle wasting increases with disease severity and is associatedwith muscle weakness and poor exercise tolerance. It is also a predictor of mortalityindependently of lung function. Structural adaptations (reduced sarcomere length,increased number of mitochondria, disrupted sarcomeres, increased content of b-spectrin) are present in the diaphragm, whereas apoptosis is observed in the vastuslateralis. Adaptation to COPD occurs earlier in the diaphragm than in peripheralmuscles. Factors related to COPD (hypoxia, hypercapnia, inﬂammation, malnutri-tion, oxidative stress) and to comorbid conditions (electrolyte disturbances, anaemia,deconditioning, ageing, level of anabolic hormones) are potential contributors tomuscle dysfunction in these patients.Keywords: Chronic obstructive pulmonary disease, diaphragm, muscle function,respiratory muscle, skeletal muscle.
Polyethylene wear in total hip arthoplasty : Polyethylene wear

Polyethylene wear increasingly has been blamed for osteolysis and granuloma formation after total joint arthroplasty. The authors evaluated the wear difference between bearing surfaces of stainless steel, cobalt chrome, and titanium alloy. They also compared cemented all-polyethylene molded cups with cemented metal-backed molded acetabular cups. These were compared with molded and machined polyethylene cups. Two patient groups were matched individually for gender, age, weight, and length of followup. Analyses were done using the technique of Livermore et al. The bearing surface evaluation consisted of 3 groups after matching, leaving 77 patients per group. Results showed linear wear rates of 0.06 mm per year, 0.05 mm per year, and 0.08 mm per year for stainless steel, cobalt chrome, and titanium alloy, respectively. The comparison between cemented molded metal-backed and nonmetal-backed acetabular components was not matched, with 134 metal-backed and 99 nonmetal-backed components. Results showed linear wear rates of 0.011 mm per year in the metal-backed group and 0.08 mm per year in the nonmetal-backed group. Results were statistically significant. These results indicate that the metal composition of the femoral bearing surface has minimal, if any, effect on the linear polyethylene wear rate. The method of polyethylene fabrication and the use of metal backing had a significant effect on the polyethylene wear rate in these patient groups. These results suggest that thc compression-molded all-polyethylene acetabular component may be optimal for reducing polyethylene wear in total hip arthroplasty.

PERSPECTIVA DOS ESTUDANTES DO CURSO DE LICENCIATURA EM FÍSICA SOBRE A COOPERAÇÃO INTERINSTITUCIONAL

This article is part of a research project of the Scientific Initiation Program (PIBIC), whose function is to encourage and support undergraduate and technical students to expand their academic backgrounds through scholarship research projects or on a voluntary basis. Considering these factors, a research was developed with the purpose of profiling the students of the undergraduate physics course, map students who perform activities related to interinstitutional cooperation and analyzing their perceptions about the interinstitutional cooperation process. Interinstitutional cooperation is of paramount importance for the development of companies, universities and research institutes, and aims to achieve better results, aiming at mutual collaboration. To achieve these objectives, a survey of available material in the area was conducted through bibliographic research and literature review, together with documentary analysis on interinstitutional cooperation developed at Federal Institute of Education, Science and TechnologyCampus Pesqueira. In addition, the application of an online questionnaire, in which 36 answers were obtained, used as a data collection instrument and, from that, to obtain the results and, subsequently, their tabulation. The research field is constituted by the Federal Institute of Education, Science and Technology Campus Pesqueira, being the subjects of the research the students of the undergraduate degree in Physics. From this, it was possible to identify several aspects regarding the students' view of interinstitutional cooperation, which indicated the low rate of student involvement in extension and research projects and the lack of knowledge about the events related to the undergraduate course in Physics and Cooperation Networks, and also, the misunderstanding regarding the concept and what are the activities carried out in the area of interinstitutional cooperation. Therefore, it is possible to systematize a framework of data and information available at the institute that can later be used as a tool for institutional knowledge management and decisionmaking processes.

ARTIFICIAL IMMUNE SYSTEM BASED FRAMEWORKS AND ITS APPLICATION IN CYBER IMMUNE SYSTEM: A COMPREHENSIVE REVIEW

Computer science has always mixed the concepts of biology and computers to enhance the way in which systems are designed. Artificial Immune System (AIS) is a Computational Intelligence strategy dependent on an organically enlivened computational system that can be utilized for taking care of complex computational issues. It tends to be seen that AIS is an incredibly various locale of research, going from the modeling immune systems to complex algorithms for specific applications. This paper exhibits an exhaustive survey of different frameworks developed in the artificial immune system and its application. Reviews of frameworks in AIS are uncommon and henceforth this paper gives an inside out audit of progressing research and challenges in AIS. We start by presenting AIS and give a thorough survey of different systems in AIS and its application in anomaly detection. We investigate the utilization of AIS in the Intrusion Detection System named the Cyber Immune System(CIS) and compares various AIS works applied to CIS. We conclude with various future extensions in the area of AIS research.
Mechanical property prediction of SPS processed GNP/PLA polymer nanocomposite using artificial neural network

Abstract The quality and performance of composite-based materials are functions of their mechanical properties. Hence, a scientific basis is needed for the determination of the feasible combination of process parameters that will bring about excellent mechanical properties. This study examines the potential of artificial neural network (ANN) for the prediction of mechanical properties, namely density and hardness of graphene nanoplatelet (GNP)/polylactic acid (PLA) nanocomposite developed under various operating conditions of spark plasma sintering (SPS) technique. A back-propagation having a 2-12-2 architecture and Levenberg–Marquardt algorithm was developed to predict the mechanical performance in terms of density and hardness property of GNP/PLA nanocomposites. The predictions of the modelled results were compared with those of the experimental value obtained. The model gave a low root-mean-squared error and performed well with the correlation coefficient (R) for both outputs; density (0.95497) and hardness (0.9832) found to be close to 1. The results of the predicted data were discovered to be very consistent with the values obtained from the actual experimental test result. Thus, our study confirmed the efficiency of a well-trained ANN system in estimating the density and hardness property of SPSed GNP/PLA nanocomposites. Hence, the ANN technique is a reliable decision-making tool capable of reducing the excessive cost incurred in experimental characterisation for newly developed polymer composites. This will serve as a decision-making tool for manufacturing industries where SPS techniques will be employed for processing GNP/PLA polymer nanocomposite.
Schiffman Phase Shifters With Wide Phase Shift Range Under Operation of First and Second Phase Periods in a Coupled Line

In this article, a class of improved Schiffman phase shifters with two C-section coupled lines separately operating in the first and second phase periods is presented and analyzed. Theoretical model and closed-form synthesis formulae are utilized to analyze the phase performances of the proposed phase shifters, which reveals significant differences compared to the phase shifters solely operating in the first or second phase period. Compared to the traditional counterparts, the proposed phase shifters can achieve a larger phase shift value and a wider phase shift range at the same impedance ratio. Moreover, under the same impedance ratio, the phase shifter can obtain wider phase shift bandwidth. These features are believed to be very useful in the limitedly realizable coupling strength for a wide phase shift range case. Finally, two sets of comparative experiments, including the operations in the first phase period, second phase period, and the proposed type, are designed and fabricated to validate the proposed approach. The simulated and measured results agree well with the theory and achieve a 33.6% (36.7%) increase in phase shift bandwidth when the phase shift value is 90° (150°) under the impedance ratio of 1.5822 (2.0312).
Small-Signal Modeling and Parameter Optimization Design for Photovoltaic Virtual Synchronous Generator

With the continuous proliferation of renewable energy generation, distributed photovoltaic inverters operating at a maximum power point reduce the inertia of power systems, degrading system frequency stability and potentially causing severe oscillations in systems after being disturbed. The virtual synchronous generator (VSG) control method, which causes photovoltaic inverters to possess inertia and damping, now plays an important role in the field of distributed generation. However, while introducing the advantages of synchronous machines, problems with oscillations are also introduced and the stochastic fluctuation characteristic of photovoltaics results in the stochastic drifting of the operating point. This paper presents an adaptive controller parameter design method for a photovoltaic-VSG (PV-VSG) integrated power system. Firstly, a small-signal model of the PV-VSG is built and a state space model is deduced. Then, the small-signal stability and low frequency oscillation characteristics of the photovoltaic power generation system are analyzed. Finally, considering the limitations of system oscillations and the stochastic drifting of the operating point, a global optimization design method for controller parameters used to improve system stability is proposed. The time domain simulation shows that an optimized PV-VSG could provide sufficient damping in the case of photovoltaic power output changes across a wider range.
