DESIGN OPTIMIZATION AND ANALYSIS OF AFPM SYNCHRONOUSMACHINE INCORPORATINGPOWER DENSITY,THERMALANALYSIS,AND BACK-EMFTHD

This paper presents the design and analysis of an inside-out axial-flux permanent-magnet (AFPM) synchronous machine optimized by genetic algorithm (GA) based sizing equation, finite element analysis (FEA) and finite volume analysis (FVA). The preliminary design is a 2-pole-pair slotted TORUS AFPM machine. The designed motor comprises sinusoidal back-EMF waveforms, maximum power density and the best heat removal. The GA is used to optimize the dimensions of the machine in order to achieve the highest power density. Electromagnetic field analysis of the candidate machines from GA with various dimensions is then put through FEA in order to obtain various motor characteristics. Based on the results from GA and FEA, new candidates are introduced and then put through FVA for thermal behavior evaluation of the designed motors. Techniques like modifying the winding configuration and skewing the permanent magnets are also investigated to attain the most sinusoidal back-EMF waveform and reduced cogging torque. The performance of the designed 1 kW, 3-phase, 50 Hz, 4-pole AFPM synchronous machine is tested in simulation using FEA software. It is found that the simulation results fully agree with the designed technical specifications. It is also found from FVA results that the motor temperature reaches Received 2 December 2012, Accepted 8 January 2013, Scheduled 20 January 2013 * Corresponding author: Amin Mahmoudi (amaminmahmoudi@gmail.com). 328 Kahourzade et al. at highest temperature to 87◦C at the rated speed and full load under steady state condition.

ELEVATED ACTIVE CONTOUR WITH GLOBAL IMAGE ENERGY BASED ON ELECTROSTATIC FORCE

In this article a new modification of the well known segmentat ion technique, namely active contour - snake, was proposed. This modificati on consists in a new formula- tion of its external force based on the electrostatics. However the base idea of giving electric charges to the image and the snake has been already presented in several works, none of them clearly adressed the problem where the charged snake took place of a charged pixel. In this situation the electrostatic force is not defined, sin ce the distance between charges is zero. The snake proposed in this work evolves on a plane elevated above the image, what never allows this distance to become zero. The method was implemented and verified on real microscopic images of oocytes, proving its superiority on the classic snake.
Near-Inertial Waves on the New England Shelf: The Role of Evolving Stratification, Turbulent Dissipation, and Bottom Drag

Abstract Energetic variable near-inertial internal waves were observed on the springtime New England shelf as part of the Coastal Mixing and Optics (CMO) project. Surface warming and freshwater advection tripled the average stratification during a 3-week observational period in April/May 1997. The wave field was dominated by near-inertial internal waves generated by passing storms. Wave evolution was controlled by a balance among wind stress, bottom drag, and turbulent dissipation. As the stratification evolved, the vertical structure of these near-inertial waves switched from mode 1 to mode 2 with associated changes in the magnitude and location of wave shear. The growth of mode-2 waves was attributable to a combination of changing wind stress forcing and a nonlinear coupling between the first and second vertical modes through quadratic bottom stress. To explore both forcing mechanisms, an open-ocean mixed layer model is adapted to the continental shelf. In this model, surface wind stress and bottom stre.
Noncompliance with Prescription Writing Requirements and Prescribing Errors in an Outpatient Department

New prescriptions received by an outpatient pharmacy department of a teaching hospital were audited retrospectively for noncompliance with prescription writing requirements as well as to identify the types of prescribing errors. Of th e 397 prescriptions screened in a single day, 96.7% had one or more of the legal or procedural requirements missing. These errors of omission, included prescriptions without the patient’s age, date, clinic or department where the prescription was issued, route of administration, dose and frequency of the drug to be used, strength, dosage form and quantity of drug to be supplied. Additionally, there were errors of commission involving 8.4% of the prescribed drugs. A total of 39 drug -drug interactions were identified; 15 were classified as potentially hazardous but could be overcome with careful monitoring of the patients. The results of the present study show a low compliance rate to the legal and procedural requirements in prescription writing. This indicates a need for pharmacy and medical educators to further emphasize the importance of writing clear and complete prescriptions. It also calls for the implementation of educational and monitoring programmes to bring more awareness to all concerned so as to reduce the rate of noncompliance and hence minimize the occurrence of prescribing errors.
Growth characteristics and vertical distribution of Triparma laevis (Parmales) during summer in the Oyashio region, western North Pacific

The vertical and regional distribution of Triparma laevis (Parmales), a siliceous picosized eukaryotic marine phytoplankton species, was investigated during summer off the south coast of Hokkaido, Japan, in the western North Pacific. Growth characteristics were also studied in the laboratory using a recently isolated culture strain. T. laevis was abundant in the subsurface layer (30 to 50 m), where water temperature was 15°C. Growth experiments revealed that T. laevis was able to grow at 0 to 10°C but not higher than 15°C, indicating that its depth distribution mainly depended on temperature. High irradiances resulted in increased growth rates of T. laevis, with the highest rates of 0.50 d ―1 at 150 umol m ―2 s ―1 . Using measured daily incident photosynthetically available radiation and in situ light attenuation, the growth rates of T. laevis at 30 and 50 m were calculated as 0.02 to 0.34 and ―0.01 to 0.08 d ―1 , respectively. Distribution of T. laevis was strongly coupled with the occurrence of Oyashio water. The growth rate of T. laevis was lower than that of bolidophytes and diatoms, which are closely related to Parmales. Bloom forming diatoms in this region have higher growth rates and a broader temperature range (0 to 20°C) and, therefore, might be expected to dominate, but Parmales does manage to co-exist in this region, albeit at a moderate abundance compared to the diatoms.
Biopsychosocial functioning among cirrhotic patients in various stages of transplant process in comparison to liver transplant recipients

Background: Although assessment of pre- and post-transplant quality of life is a current scientific target; it has not yet been carried out throughout the entire transplant process. Aims: 1) To analyze differences in mental health and quality of life at pre-waiting-list-study, waiting-list, and post-transplant phases; 2) to analyze correlation between these quality- of-life and affective variables and Model for End-Stage Liver Disease (MELD) scores. Methods: Two liver patient groups were recruited: 51 cir- rhotic patients, who were assessed at two different stages (at pre-waiting- list-study and waiting-list phases), and 51 cadaveric liver transplant recipi- ents; groups were homogeneous in gender and age variables by matching. Anxiety-depressive symptomatology and quality of life were assessed by HADS and SF-36 Health Survey, respectively. Results: Pre-waiting-list-study patients self-perceived their global health status much worse than trans- plant recipients. Waiting-list patients displayed much higher anxiety, more role limitations due to physical problems, worse physical functioning, as well as perceiving their global health status much worse than transplant re- cipients. Statistically significant correlations were only found in waiting-list patients between MELD-Anxiety and MELD-Social Functioning sub- scales. Conclusions: Waiting-list patients displayed the worst biopsychosocial well-being status; liver transplant recipients enjoyed the best status instead.
3D Finite element analysis of smooth muscle contraction considering calcium diffusion

Recently a model of the mechanochemical response of smooth muscle cells has been developed by Murtada et al. [1]. The model is based on a strain-energy function incorporating only a few physical-based material parameters. The main focus of their approach is on the modeling of the response of the cross-bridge interactions and on the related force generation. Based on a one-dimensional analysis the performance of the modeling approach has been shown by comparing to experimental data of smooth muscle cells. The results of the combined coupled model are broadly consistent with isometric and quick-release experiments on smooth muscle tissue. In the present study the aforementioned model has been implemented into a finite element program in order to solve more complex boundary-value problems. In doing so we present here a first three-dimensional simulation of the Fick's law-driven diffusion of calcium into a cell as well as the related smooth muscle contraction.
To Buy or To Lie: Determinants of Purchase Intention of Counterfeit Fashion in Malaysia

In the competitive market of the fashion industry, counterfeit fashion has become prominent and also a great threat to the original brands in the market. The study seeks to investigate the factors that affect consumers’ purchase intention towards counterfeit fashion products (CFP). Constructs of past experience of consumers, perceived risk, social influence, attitudes of consumers towards the purchase intention of counterfeit fashion products were explored through the distribution of 350 questionnaires. 284 usable data is analysed and the results showed that past experience and social influence have the most significant influential effect towards the purchase intention of CFP. The results also proved that consumers’ attitudes towards CFP have a mediating effect and gender moderates between past experience and purchase intention. This research discusses the implications towards authentic brand manufacturers in fashion industry and recommendations for future research studies, which will help the researchers in conducting related research more accurately.
Implementation of Biometric Security usingHybrid Combination of RSA and SimpleSymmetric Key Algorithm

The objective of this research proposal is to design new bio metric security protocol using hybrid encryption system. The hybrid encryption technique is a combination of both symmetric and asymmetric cryptographic techniques. The security of bio-metric information transfer through unreliable channel is challenging, because of external attacks. Therefore, Security of biometric information is essential requirement in this current trend and technology. The various protocols such an AES, DES, 3 DES are currently using biometric solution. But, the key distribution and encryption and decryption cycle is major problem. The new protocol solves make more secure and easy to encrypt and decrypt the data. Thus, in this paper, we propose new efficient and effective mechanism for confidentiality and authentication for biometric security system by using RSA and simple symmetric key algorithm. Also it examines the possibility of using a combination of biometric attributes to overcome common problems in having a biometric scheme for authentication. It also investigates possible schemes and features to deal with variations in Biometric attributes.
Dogmatism and non-intellective factors among counselor and non-counselor trainees /

3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete.

Unsteady Numerical Simulations of Flow around Heavy Vehicles, Trains and Passenger Cars

In this thesis several simulations have been carried out aimed at improving the knowledge of vehicle aerodynamics and improving the flow around vehicles with respect to the aerodynamic drag. Four flows around different simplified vehicles have been considered. One model of a tractor-trailer, one passenger car model, one freight wagon model and one regional train model. The simplified tractor-trailer model consists of a front box representing a tractor and a rear box representing the trailer. The two boxes are separated by a gap width which is varied in the simulations. In the simulations on this geometry, the focus is on the flow in the gap between the tractor and the trailer and how this flow affects the global drag on the model. Large Eddy Simulation is used to simulate the flow around four variants of the model with different geometrical configurations. The behavior of the drag coefficient of the tractor-trailer model when varying the gap width and the shape of the front edges on the tractor is explained by identifying and analysing the large vortices around and in the the gap. The focus in the study on the passenger vehicle model is on the so-called A-pillar vortex. This is a swirling longitudinal vortex formed along the side windows on passenger vehicles due to the separation of the flow from the side edges of the front window and the engine hood. Flow control, both blowing and suction, from actuators located on the side of the front of the model is applied in the LES simulations. Steady blowing into the vortex causes expedited breakdown of the vortex, which in turn influence the pressure distribution on the side windows and the overall drag of the model. Steady suction causes the vortex to not form at all, thereby removing the vortex entirely. Simulations aimed at improving the knowledge on the flow around a generic freight wagon model using LES is also reported. The model is smoothed in comparison to a real container wagon, but the overall geometrical features such as wheels and underhood are included. The simulations of the flow around the regional train model is done using Partially Averaged Navier Stokes (PANS). PANS is a recently proposed hybrid turbulence model for engineering types of flow. The regional train model consists of a bluff body with a length to height/width ration of 7:1. The model poses several challenging flow situations to simulate such as separation from the leading curved front edges, an attached boundary layer flow and separation from the curved rear edges at the moderate Reynolds number of 400 000 based on the models’ width. An open cavity is placed on the model at the base and the drag is thereby decreased by some 10%
Characterization of carbon nanotube/graphene on carbon cloth as an electrode for air-cathode microbial fuel cells

Microbial fuel cells (MFCs), which can generate low-pollution power through microbial decomposition, have become a potentially important technology with applications in environmental protection and energy recovery. The electrode materials used in MFCs are crucial determinants of their capacity to generate electricity. In this study, we investigate the performance of using carbon nanotube (CNT) and graphene-modified carbon-cloth electrodes in a single-chamber MFC. We develop a process for fabricating carbon-based modified electrodes and Escherichia coli HB101 in an air-cathode MFC. The results show that the power density of MFCs can be improved by applying a coat of either graphene or CNT to a carbon-cloth electrode, and the graphene-modified electrode exhibits superior performance. In addition, the enhanced performance of anodic modification by CNT or graphene was greater than that of cathodic modification. The internal resistance decreased from 377 kΩ for normal electrodes to 5.6 kΩ for both electrodes modified by graphene with a cathodic catalyst. Using the modified electrodes in air-cathode MFCs can enhance the performance of power generation and reduce the associated costs.
Pressure gradient effect on a particle velocity distribution

In space plasma missions, measurements of the three‐dimensional particle velocity distribution are used to examine the dynamical evolution of plasmas. The first velocity moment of the measured particle velocity distribution is often regarded as the bulk flow of the population. Accurate determination of bulk flows is crucial if the frozen‐in‐condition is judged by E + V × B = 0, where E is the electric field, V is the bulk flow, and B is the magnetic field. In this paper, we show that this first velocity moment computed from the measured particle velocity distribution can deviate substantially from the bulk motion of the particle population when a significant pressure gradient exists near the measurement location. The discrepancy, which arises from the diamagnetic drift with a finite Larmor radius effect, increases with increasing energy range used in the computation. The result calls for caution in the proper interpretation of this velocity moment and suggests a means to avoid error in the determination of bulk flow due to pressure gradient effects.
Monetary Policy Efficiency in the Economies of Central Asia

This study examines monetary policy efficiency in Central Asia by investigating the monetary transmission mechanism in the region’s economies. To examine monetary policy efficiency, it is necessary to take into account factors that might impede the transmission, such as high levels of dollarization, weak financial sectors, underdeveloped capital markets, and low monetization of economies. Empirical findings confirm the importance of exchange rate pass-through in transition economies with high dollarization. The findings also provide an empirical case for deepening the local financial sectors to improve the efficiency of monetary policy and to improve resilience to external and other shocks.
Investigation of the effect of passive vortex inserts of different geometrical shapes on the vibrations reduction efficiency in pipelines with two-phase flow

This paper describes the experimental test bench used in coolant flow research with application of adjusted optical laser system. It is based on the technology of pulsed particle visualization of micro tracers, i.e. Particle Image Velocimetry (PIV system) that allows for the analysis of the microstructure of the hydrodynamic liquid flow passed through the vortex inserts. Optical measurement (PIV-method) of hydro- and aerodynamic characteristics of the coolant flow allowed obtaining the velocity distribution in straight and various curved sections of the pipeline in order to reliably define the vortex formation condition and the occurrence of the pressure gradient on the outer and inner walls of the curved sections. This gives us the opportunity to verify the calculation models describing the problem of passive control (decrease) of the displacement of pipelines of power equipment, and thus to improve the reliability and safe operation of the system in general.
Eiji Yamamura Death tolls from natural disasters: Influence of interactions among fiscal decentralization, institutions and economic development Natural disaster, law and order, corruption, economic development EERI D73; K10; O1; Q54

Previous research shows that decentralization plays a key role in the reduction of damage caused by natural disasters. The effect of decentralization will differ according a country’s level of economic development. To investigate this matter further, this paper attempts to investigate how quality of institution influences the effectiveness of decentralization. This paper uses cross-country data from 1990 to 2000 to examine how decentralization, institution, and economic development influence the number of deaths caused by natural disasters. The major findings are that decentralization reduces deaths and its effect is strengthened in countries with lower level of public sector corruption and better functioning legal systems. Furthermore, the interaction between decentralization and high quality institutions has a greater contribution to the reduction of deaths in more developed countries. This implies that decentralization makes a greater contribution to mitigating damage in countries with higher quality institutions. However, when essential technology does not exist, decentralization and quality of institution play only a minor role in the mitigation of damage in the event of a natural disaster.
Use of littoral benthic invertebrates to assess factors affecting biological recovery of acid- and metal-damaged lakes

Abstract Biological recovery of aquatic ecosystems from acidification damage is a slow process. In lakes near the massive Cu and Ni smelters in Sudbury, Canada, the delays might be caused by residual metals, habitat damage, altered predator–prey interactions, or other persistent ecological stressors. Assessments of benthic invertebrate communities in 24 Sudbury lakes were conducted to evaluate the relative importance of these delaying factors. At the time of sampling, all lakes had chemically recovered to a pH >6.0, but they varied widely in the duration of time above this threshold and in current metal concentrations, watershed contributions of organic matter, littoral habitat composition, and fish community composition. A model developed with redundancy analyses (RDA) of 4 groups of environmental variables (i.e., water chemistry, fish communities, physical lake descriptors, and littoral habitat) accounted for 74.9% of the variance in benthic invertebrate community metrics across these environmental gradients. Fish species richness, duration of pH recovery, and % boulder habitat were the most significant variables and explained 22%, 9%, and 8% of the variance in benthic invertebrate community metrics, respectively. Damaged systems clearly need sufficient time to recover from severe disturbances. However, our study suggests that remediation techniques, such as manipulation of predator–prey interactions through fish introductions, might speed the recovery of benthic invertebrate communities.
