Comparison of Different Bearing Couples of Hip Resurfacing Prostheses: A Finite Element Study

Friction couples are still unsolved problems, and the optimal choice depends on the patient’s age, level of activity and functional requirements. Finite element (FE) study was performed to investigate the contact mechanics and stress/strain distribution of hip resurfacing for different bearing couples. Ceramic-ceramic or ceramic-metal bearing couples reduce adhesive wear that also reduces osteolysis. There is, however, a problem of stem fracture risk of femoral component because of brittle alumina. Stress shielding within the bone tissue, was also found to be the major concern regarding the use of ceramic as an alternative to metallic resurfacing prostheses. All these bearing couples require to be supported by clinical studies to provide surgeons an appropriate choice of bearing materials.
Effects of office environment on employee satisfaction: a new analysis

Two large and detailed field studies of the effect of office environment parameters on aspects of environmental and job satisfaction were conducted. The first study focused on open-plan offices in nine conventional buildings, whereas the second encompassed open-plan and private offices in 24 buildings (12 green and 12 conventional). The data collection for these studies was separated by approximately a decade, but the data collection methods, contexts and analysis procedures were very similar. This offered the opportunity to compare the results of the studies at the workstation level, with the goal of identifying parameters consistent in affecting occupant satisfaction, and of exploring the effects of office type (open-plan versus private) and building type (green versus conventional). Satisfaction with acoustics and privacy was most strongly affected by workstation size and office type; satisfaction with lighting was most strongly affected by window access and glare conditions; and satisfaction with ventilation and temperature was most strongly affected by pollutant concentration. Occupants of green buildings rated all aspects of environmental satisfaction more highly. Finally, job satisfaction was most strongly affected by pollutant concentration and office type.

Bilevel Formulation for Optimal Traffic-Information Dissemination

With the fast-growing telematics market and maturing traffic-information services, telematics devices provide a feasible means with which to manage traffic more efficiently. The provision of traffic information to travelers usually involves different parties that have distinctive objectives: travelers are concerned with benefits of travel-time savings at an affordable service charge, private information service providers (ISPs) seek to provide marketable information services from which they can derive a profit, and traffic management centers (TMCs) have the responsibility to maintain and improve system performance, especially to minimize the total system travel time. How transportation system managers can analyze the trade-offs among these objectives and adjust this new traffic-information flow diagram to improve system performance remains an open question. The trade-offs needed among the conflicting multiple objectives of different parties are studied, and traffic system performance is analyzed. The complex traffic network is formulated as a bilevel program. The upper level can be formulated by using various objective functions, such as the objectives for ISP and TMC. The lower level is a multiclass dynamic traffic-assignment model, which determines dynamic traffic flows in the network by considering the information dissemination strategies provided by the upper-level model. Numerical results of a small network are provided to illustrate the behavior of this model, and they prove that when there is congestion in the dynamic transportation network, appropriate subscribed rates benefit both all travelers and system performance, while the ISPs’ information influences little without congestion in the transportation network.
Prediction of Grade of Urothelial Carcinoma of Urinary Bladder from the Size and Number of Tumors at First Presentation

Background: Early diagnosis and prompt treatment can save lives of the patients with bladder cancer. The confirmatory test for grade of the disease is histopathological examination after transurethral resection. But if the grade of the tumor can be predicted at the time of presentation from size and number of tumors seen by ultrasonographic imaging, clinician can counsel the patient beforehand and also arrange rapid treatment to save life. Objective: To assess the size and number of tumors as clinical predictors of histological grade of urothelial carcinoma of urinary bladder before first-time transurethral resection of the bladder tumor (TURBT). Methods: This cross-sectional study was conducted in the Department of Urology, BSMMU and RGRH from January 2020 to April 2020. Fifty patients were enrolled in this study. Size and number of the tumor was determined by preoperative ultrasonography of urinary bladder. Histopathological examination was used to determine the grade of the tumor after TURBT. Statistical analysis was performed using SPSS version 22.0. Results: Mean age of the study subjects was 52.04 ± 18.37 years within the range of 22–95 years. Males (56.0%) were predominant than females (44.0%). Male to female ratio was 1.27:1. Mean number of tumor was 1.28 ± 0.64 (1-3) and mean tumor size was 3.54 ± 1.47 cm (1-7). High grade tumor was 26 (52.0%) and low grade tumor was 24 (48.0%). There was no significant association of tumor grading with number of tumor in this study. High grade tumor was significantly higher among the study subjects with tumor size >3.5 cm. Area under curve (AUC) of tumor number and tumor size was 0.558 and 0.827 respectively in prediction of tumor grading. Sensitivity, specificity, PPV, NPV and accuracy of tumor number (at cut of value 3) was 15.4%, 95.8%, 80.0%, 51.1% and 54.0% respectively. Sensitivity, specificity, PPV, NPV and accuracy of tumor size (at cut of value 3.5 cm) was 90.5%, 76.3%, 80.9%, 87.9% and 83.7% respectively. Overall Sensitivity, specificity, PPV, NPV and accuracy of tumor size was better than tumor number in prediction of tumor grading. Conclusion: According to this study finding, it can be concluded that the grade of newly diagnosed bladder tumors can be predicted with high accuracy using tumor size.
Novel approach for characterizing the specific shunt resistance caused by the penetration of the front contact through the p–n junction in solar cell

Shunt can drastically decrease the solar cell conversion efficiency and its current measurement result only reflects the overall shunting effect of all shunts in a whole cell. In order to accurately characterize local shunts caused by the penetration of front contacts through the emitter junction, silicon solar cells with a new structure named beam bridge contact were fabricated. The result showed that the region under the emitter was more badly shunted than the other emitter regions. The sample preparation process was completely compatible with the industrial silicon fabrication sequence, which was of great convenience. The measurement results give informations on the solar cell structure, material ingredients, and process parameters.

In this paper, we present the properties a quantum well material for InGaP quantum well solar cells and the performances of the dual-junction dual-MQW devices. We demonstrate that this dual-junction device can achieve 28% efficiency at 100 suns, which can be further improved by reducing the series resistance in the device.
Mitigation of windfarm power fluctuation by adaptive linear neuron-based power tracking method with flexible learning rate

Most wind turbine generators installed in large windfarms are of variable speed types operating at the maximum power point tracking mode to generate the maximum amount of power. Owing to this fact and regarding the random nature of the windspeed, the output power of the windfarm fluctuates. Fluctuating power is a serious problem for high capacity power plants and should be smoothed. As an effective factor on the required battery energy storage system (BESS) capacity value, tracking is the most important part performed by a coordinated control system in the power smoothing process. An ADAptive LInear NEuron (ADALINE)-based power tracking method with a flexible learning rate is proposed in this study. Furthermore, a particle swarm optimisation-based calculation of the learning rate is presented for optimising the proposed tracking method which reduces the required BESS capacity and the investment cost. Moreover, a charging/discharging algorithm for the BESS units is proposed which decreases the number of required BESS units and increases their useful life by reducing the switching activity as well. To evaluate the performance of the proposed coordinated control approach, the real output data of a 99 MW windfarm are tested. The simulation results verify the effectiveness of the proposed approach.
Driving backwards using a semi-autonomous smart wheelchair system DSS: A clinical evaluation

Some wheelchair users have difficulty looking backward when backing up in confined spaces due to limited neck range of motion or low vision, which can lead to collisions which may result in personal injury or property damage. The Drive Safe System DSS was evaluated in a controlled laboratory setting with blindfolded able-bodied individuals on various backward driving tasks. Performance with the DSS was compared with a standard white cane used for navigation assistance by people with visual impairment. Results indicate that the DSS significantly reduced the number of collisions compared to using a cane p = 0.0001 alone. There was no difference in task completion time when participants were using the cane or the DSS p = 0.915. Users rated the DSS favourably as they experience less total workload p = 0.026, less physical demand p = 0.006, felt less frustrated p = 0.002 and put less effort p = 0.007 to achieve better performance when using the DSS, compared to using a cane. These findings suggest that the DSS can be a viable powered mobility solution for wheelchair users with visual impairments.
A selective improvement technique for fastening neuro-dynamic programming in water resources network management

Abstract An approach to the integrated water resources management based on Neuro-Dynamic Programming (NDP) with an improved technique for fastening its Artificial Neural Network (ANN) training phase will be presented. When dealing with networks of water resources, Stochastic Dynamic Programming provides an effective solution methodology but suffers from the so-called “curse of dimensionality”, that rapidly leads to the problem intractability. NDP can sensibly mitigate this drawback by approximating the solution with ANNs. However in the real world applications NDP shows to be considerably slowed just by this ANN training phase. To overcome this limit a new training architecture (SIEVE: Selective Improvement by Evolutionary Variance Extinction) has been developed. In this paper this new approach is theoretically introduced and some preliminary results obtained on a real world case study are presented.
TINA architecture extensions to support terminal mobility

The need for convergence of mobile and fixed networks at service control and management level is a key issue in the telecommunications environment. The existence of a generic service layer spanning over a set of heterogeneous networks promises several advantages for greater flexibility and efficiency in service development and deployment. TINA-C has established an architecture that has the potential and momentum to respond to such challenges. However, several adjustments and refinements to both the TINA network and services architectures appear necessary when addressing mobility. Mobile communications force the architect to re-think how to include both personal and terminal mobility in the architecture. In this paper we describe a way to apply the TINA network resource architecture (NRA) to terminal mobility and particularly to handover support. In addition, to exploit various wireless technologies in the delivery of multimedia services, we have developed a way of adapting mobile wireless networks so that some aspects of quality-of-service and traffic classes can be supported to an extent that would not be directly allowable by the underlying infrastructure. Our solution is based on the entity called the mobile network adapter (MNA) that tries to overcome the limitations due to lower layer protocol architectures, thanks to a smart, generic, mobility-aware management of resources. We also report design and real experience gained while implementing the TINA architecture on top of a telecommunications infrastructure, involving GSM, ATM and wireless LAN (WLAN) transport networks. Our studies and experiments revealed the need for introducing specific extensions/refinements to the NRA. These extensions/refinements represent the key contribution of this paper.

Assessing Health Literacy in Iran: An Image in Two Frames

Background: The aim of this study is to draw a comprehensive picture of patients’ functional and critical health literacy and its association with socio-demographic variables and self-efficacy. We investigated the referrals to Isfahan health centers, in particular the dimensions of reading ability, numeracy and eHealth literacy using two different measures, NVS for the functional and the eHEALS for critical aspects. Methods: For testing individuals with low health literacy, the NVS is a reliable and quick screening tool. eHEALS helps to measure patients’ capabilities in Internet searches. Both of tools are validated in Persian. The measures were administered to a random sample (N = 384), which resembled Iran residents in terms, educational attainment and self-efficacy but not age and gender. Pearson’s correlation coefficient, χ2-test, independent t-test and regression were also used to assess the association between health literacy measures, self-efficacy and predictor variables. Results: More than 60% of our respondents had an inadequate or marginal level of health literacy with NVS, and with eHEALS, more than 50% were classified accordingly. NVS and eHEALS scores showed an association with higher education one of the predictors of health literacy. Higher eHEALS scores were associated with higher self-efficacy. eHEALS provides a valid self-reported assessment of patients’ eHealth literacy, and NVS provides a useful appraisal of patients’ functional health literacy. Conclusions: In our sample, more than 50% of patients had a low level of literacy. eHEALS provides a valid self-reported assessment of patients’ eHealth literacy, and NVS provides a useful appraisal of patients’ functional health literacy. Determining health literacy in patients leads to a better understanding of their perception, application and decision-making in health problems.

A Study on the Electrical Properties of ZnO Based Transparent TFTs

The purpose of this work is to present in-depth electrical characterization on transparent TFTs, using zinc oxide produced at room temperature as the semiconductor material. Some of the studied aspects were the relation between the output conductance in the post-pinch-off regime and width-to-length ratios, the gate leakage current, the semiconductor/insulator interface traps density and its relation with threshold voltage. The main point of the analysis was focused on channel mobility. Values extracted using different methodologies, like effective, saturation and average mobility, are presented and discussed regarding their significance and validity. The evolution of the different types of mobility with the applied gate voltage was investigated and the obtained results are somehow in disagreement with the typical behavior found on classical silicon based MOSFETs, which is mainly attributed to the completely different structures of the semiconductor materials used in the two situations: while in MOSFETS we have monocrystalline silicon, our transparent TFTs use poly/nanocrystalline zinc oxide with grain sizes of about 10 nm.
Improved Methods for Departments' Intention for RFID Use

Radio Frequency Identification (RFID) Government departments and enterprises in Taiwan apply RFID universally in the fields of animal microchip, door access management, Auto chip of anti-theft de-vice, MRT Easy Card, parking lot man-agement, anti-counterfeiting and material management, but the multifunctional in-telligent card with integration of RFID applications has not been developed so far. If we can develop a card with integration of the functions which are closely related to people's daily life such as ID card, NHI IC card, fingerprint, E-signature and E-commerce (E-wallet), it will not only save time and money spent on applying these cards for people, but also will lower the governmental ex-penditure and achieve the effect of energy saving and carbon reduction. The previous studies mostly explore the factors affecting the user’s intention and behavior of RFID use from the initial beliefs (ease-of-use and usefulness) and attitude. For example, to what extent the knowledge, belief, attitude, perceived value, it deserves further exploration. To resolve the above problems, this study out differences from Social cognitive theory, Innovation Diffusion theory and Expectation confirmation theory, and establishes the theory model of the user's intention and behavior of using RFID continuously, which is also verified in this paper.
