Mapping a Strength-Oriented Approach to a Standardized Terminology: A Case Study

As a new era of healthcare advocates a more valuable and intelligent approach to care management and delivery based on values and outcomes, shifts toward risk management to boost performance should be considered that encompass the capitalization of health assets or health strengths. To make full use of individuals' or populations' health assets, data capture and representation are needed. This paper uses a strengths-oriented case study mapped to an inter-disciplinary standardized terminology, the Omaha System, to illustrate and compare the conventional problem-based approach to care management with the strengths-oriented approach to care that demonstrates whole-person data capture of an individual's health and health assets leveraged to promote health values and performance. The Omaha system provides a standardized framework to organize the concepts of all of health from a whole-person perspective for documentation to enable data analysis, interoperability, and health information exchange.
Model predictive traffic control for green mobility

This tutorial provides a short overview of model-based predictive control approaches for traffic management using multiple performance criteria, including green mobility performance measures such as reduction of emissions and reduction of fuel consumption. In this paper we will briefly discuss the most important aspects of the topic, while also providing the interested reader with a non-exhaustive list of references that provide a more in-depth treatment of the subject. We start with a brief description of traffic management. Next, we discuss traffic flow and emission models, with an emphasis on macroscopic models, as they are well suited for on-line model-based predictive traffic control, highlighting the importance of the balance between accuracy and control performance. Next, we focus on the use of model-based predictive control (MPC) for coordinated control of various traffic control measures in small-scale freeway networks. Finally, we discuss various ways to improve the computation speed when solving the MPC optimization problem.

Designers should be equipped with detailed non-linear frequencydependent models to be able to simulate circuit performances in a pre-production stage. The paper gives a report how the models of conveyors can be composed. The Analog Behavioral Modeling (ABM) techniques are utilized.
Impact of Telework on Exhaustion and Job Engagement: A Job Demands and Job Resources Model

Teleworking, the increasingly common practice, which involves working away from the office using technology, entails changes in the experience of work. Such changes may influence the demands and resources associated with a job. While research on burnout has addressed the role of exhaustion and job engagement using the Job Demands‐Resources model, existing literature has focused on traditional work modes. This paper explores the effects on job demands and resources to understand the processes through which telework impacts the exhaustion and engagement of the teleworker. We find that the positive effect of telework revolves around reduced work pressure and role conflict and increased autonomy. The negative effect of telework is expressed through increased role ambiguity and reduced support and feedback. Overall, we find that telework is negatively related to both exhaustion and job engagement and that job demands and resources mediate these relationships.
Extending the bandwidth of magnetic tunnel junction sensors by a buffer amplifier

A simple buffer amplifier, consisting of a transistor in an emitter-follower configuration, is proposed to extend the bandwidth of magnetic tunnel junction read sensors. To maximize the bandwidth improvement, the buffer should be used on the slider or on the suspension as near to the slider as possible. The channel front-end (sensor, buffer, interconnect, and preamp) bandwidth is still somewhat limited by the RC product of the sensor resistance and shunt capacitance. However, the buffer can reduce the shunt capacitance to subpicofarad levels, allowing for bandwidths near 1 GHz. Merging the buffer with an interconnect and preamp gives a low-frequency signal-to-noise ratio (SNR) reduction at the preamp input of 0.1 dB and an SNR improvement of 5 to 10 dB over a no-buffer configuration for frequencies between 100 MHz and 1 GHz.
Introduction of a hybrid multi-converter system and its control strategy

A hybrid converter system aiming at a higher voltage higher capacity higher efficiency converter system having fewer harmonics in its output is proposed. The system consists of a GTO inverter operating in a square-wave mode and a neutral-point-clamped IGBT inverter operating in a PWM mode. The former produces a base part of the resultant output. The latter produces an additional part of the resultant output as well as eliminates the harmonic components generated by the GTO inverter. A basic control strategy for both inverter and rectifier operation of the system is proposed. Furthermore, an attainable output capacity, device losses, and current THD of the hybrid system, when available devices in the market are used, are estimated. It is concluded that the hybrid system has an advantage over the others in terms of efficiency and harmonic distortion.
Learning building pathology using computers – a prototype application

Building defects are notoriously difficult to identify, even by the most experienced surveyor. Traditional training methods of identifying defects in buildings involved the physical visiting of a property. This has become more difficult as insurance and organisational issues have made this practice unsafe and costly. Methods of training surveyors can be brought up to date with the introduction of desktop technology to provide learners with a rich set of learning resources in a much easier format. Defects generated from real life cases using digital cameras are stored in a format that can be transformed into QuickTime VR movies and then used to train inexperienced surveyors. This paper describes a prototype application using case‐based‐reasoning virtual reality and multimedia authoring technologies. The architecture of the system is described and some details of the methodology used are discussed. An iterative approach is used to develop the system and validate it.
Distributed Extended State Estimation for Complex Networks With Nonlinear Uncertainty

This article studies the distributed state estimation issue for complex networks with nonlinear uncertainty. The extended state approach is used to deal with the nonlinear uncertainty. The distributed state predictor is designed based on the extended state system model, and the distributed state estimator is designed by using the measurement of the corresponding node. The prediction error and the estimation error are derived. The prediction error covariance (PEC) is obtained in terms of the recursive Riccati equation, and the upper bound of the PEC is minimized by designing an optimal estimator gain. With the vectorization approach, a sufficient condition concerning stability of the upper bound is developed. Finally, a numerical example is presented to illustrate the effectiveness of the designed extended state estimator.

Effects of Repetitive Transcranial Magnetic Stimulation on Upper Extremity Spasticity Post-Stroke: A Systematic Review

Abstract Upper extremity spasticity is one of the most popular impairments following stroke. It can reduce patients' functional level. Recently, repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising tool in stroke rehabilitation. This review was conducted to investigate the immediate and long-term effects of rTMS on the upper extremity spasticity post-stroke and determine the optimal treatment protocols. PubMed, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, AMED, and Web of Science databases were searched for randomized controlled trials investigating the effect of rTMS on the upper extremity spasticity in patients with stroke. The methodological quality was assessed using the Cochrane Collaboration’s tool. Ten randomized clinical trials were met the inclusion criteria. A total of 225 patients were included in this analysis, 35.30% of whom were females. The mean age for all patients was 60.14 years. The findings showed heterogeneous evidence on the benefits of rTMS intervention in the upper extremity spasticity post-stroke. The evidence for the effect of rTMS on the upper extremity spasticity post-stroke is promising. Combining rTMS with other rehabilitation interventions may show a superior effect in reducing the upper extremity spasticity compared with rTMS intervention alone. Further randomized controlled trials with long-term follow-ups are warranted.
Control and hysteresis reduction in prestressed curved unimorph actuators using model predictive control

Curved piezoceramic unimorph actuators exhibit strong nonlinearities due to their special architecture that enables large motion amplification. Among these nonlinearities, hysteresis is the most problematic as it makes it difficult to predict the displacement of the actuator for a given input voltage. Therefore, it has been difficult to use these actuators in precision displacement control applications. In order to overcome this difficulty, this research is focused on the development of an effective reference-tracking displacement control algorithm for such actuators. For this purpose, two linear (proportional–integral and internal model) and two nonlinear (sliding mode and model predictive sliding mode) controllers are designed and implemented. These controllers are applied to the curved piezoceramic unimorph actuator to control the displacement of the actuator for multiple sinusoidal voltage inputs at various frequencies. Experimental results are obtained, and their performance is compared both qualitatively and quantitatively. As a part of the model-based controller design, a new actuator model is also developed based on the mechanical second-order equation with an additional phase lag term to describe the hysteretic effect.
Development and design of an FPGA-based encoder for NPN

Abstract This paper describes a cryptographic protection system hardware device designed to improve data encryption and decryption performance and preserve data integrity. The cryptosystem is implemented by hardware-software method, where the encryption and decryption of data are carried out in a stand-alone FPGA device based on non-positional polynomial number system (NPN). For data encryption the next block of text to be encrypted is divided into sub-blocks and represented as separate binary polynomials and binary polynomials-keys are assigned to them, as well as irreducible polynomials (modules). Then, split blocks are calculated in parallel and a ciphertext is formed. For this purpose, the special algorithm where calculation of NPN parameters and check on irreducibility of polynomials (modules) and the program of generation of direct and inverse keys are developed and application functional is developed that implements operations in the ring of polynomials with coefficients GF(2) using an object-oriented approach. We have developed polynomial multipliers modulo sequential and parallel action (matrix multiplier) on the basis of which data encryption and decryption are performed.
Company Size and Human Factors and Ergonomics Awareness

The objective of this study was to better understand the knowledge and opinions of managers in the American furniture manufacturing industry regarding Human Factors and Ergonomics (HF/E) and to explore significant relationships between company size and managers' awareness on HF/E. The furniture manufacturing industry has a high occupational injury and illness rate and HF/E awareness is vital to improve worker safety and health. A web-based survey was used to gage managers' awareness of HF/E. Development, pre-test, and review stages followed to design the final survey. Sixty-four managers participated in the survey. This study shows the awareness level of managers depended on company size. Smaller companies were less likely to provide HF/E training programs to both managers and employees, additionally; smaller companies were less likely to have a team or department for HF/E interventions or for establishing HF/E programs in their organizations. The main reason for lower commitment to HF/E in small companies is owners, managers, and employees had a low awareness about the importance of HF/E to improve their occupational injury and illness rates. For example, 75 percent of the managers surveyed rated their HF/E knowledge level as poor, fair, or average. Some of the managers were not aware of available information resources about HF/E. A considerable number of managers believed that HF/E resulted in more regulations to follow and higher cost in training new employees. Without managers' commitment and support, the success of HF/E programs is not likely. In summary, our findings indicate managers in small companies are not well informed of the importance HF/E awareness plays in controlling their injury and illness rates. Therefore, we feel managers of any sized company especially smaller companies should be introduced to available HF/E resources and the benefits of HF/E.
Performance of coherent square M-QAM with L/sup th/ order diversity in Nakagami-m fading environment

The symbol error rate (SER) performance of coherent square M-ary quadrature amplitude modulation (M-QAM) with L/sup th/ order diversity frequency non-selective slowly Nakagami-m (1960) fading environment corrupted by additive white Gaussian noise (AWGN) is presented. The diversity combining technique considered in this paper is maximal ratio combining (MRC) with identical channels. The derived expression for SER is in terms of a single finite integral with an integrand composed of elementary (trigonometric) functions. Because of its simple form, the expression readily allows numerical evaluation for cases of practical interests. The solution presented in this paper is general enough so that it includes half Gaussian fading (m=0.5), Rayleigh fading (m=1), and nonfading (m=/spl infin/) as special cases. The results are plotted as SER versus signal to noise ratio (SNR) for various values of m and L to examine the dependence of the performance of MQAM on m and L. The results presented are expected to provide useful information needed for exploiting the use of diversity for design of better communication systems in Nakagami-m fading environment.
Improved Four-Level Neutral Point Clamped Converter

As a trade-off solution for medium-voltage (>1.5kV) and large-scale photovoltaic generation application, the four-level converters show less components than five-level converters and lower blocking voltages than three-level converters. However, the existing voltage balancing methods for the four-level converters, such as 4L-NPC converter, usually leads to increased voltage stresses across some inner power devices. To improve this problem, one improved 4L-NPC converter is proposed based on the existing 4L-NPC converter. With the adoption of voltage balancing control, the proposed improved 4L-NPC converter is featured with: (a) no flying capacitors; (b) uniform and small voltage stress that is 1/3 of the total input voltage. Simulation studies have been presented to verify the proposed topology.
Effects of Drought Stress on Cotton Output and Fiber Property of Different Cultivars

Under adverse soil situations and simulated extreme climatic conditions, use the orthogonal design method and study the effect of 3 cultivars (Xinong Kang NO.4, NO.5 and Zhong mian NO.41 on lint output and quality by conducting the coupling water saving farming practice. The results showed that K4 and K5 perform better in output than the control (Zhong mian NO.41) and appeared drought resistant to some extent. No irrigation or with few irrigation (water saving), the outputs of the plots of irrigation regions suffering from water stress are better than control (irrigating two-three times), average output is increased by 8.11%. Compared with control, the plots with optimal combination of water saving farming practices and drought resistance have higher lint outputs and various fibers, increased by 4.62%~13.76% and by 5-10% on average separately. These demonstrated that coupling of water saving farming practices and drought-resistant varieties had significant effects on cotton output and quality, it provides water-saving agriculture engineering theory basis for the arid and semi-arid area.
Open-Circuited Faults Diagnosis of a Nine-Phase Permanent Magnet Synchronous Motor Drive System Based on Mean Phase Current

The open-circuited faults of IGBT and winding are inevitable for the multiphase permanent magnet synchronous motors (PMSMs) drive systems. It is necessary to detect and locate faults in time to ensure the motor operates safely. In this paper, a method of mean phase currents (MMPC) is used to diagnose open-circuited faults of IGBT and winding of a nine-phase PMSM system. Firstly, the mathematical model of nine-phase PMSM is established. Secondly, the method of mean phase currents is introduced to diagnose the IGBT and winding open-circuited faults. Finally, the correctness of the faults diagnosis method is verified by different open-circuited faults simulations and experiments of a 9kW nine-phase PMSM system.
Histopathological Analysis of Acinetobacter baumannii Lung Infection in a Mouse Model

Abstract Acinetobacter baumannii is the main causative pathogen of nosocomial infections that causes severe infections in the lungs. In this study, we analyzed the histopathological characteristics of lung infection with two strains of A. baumannii (ATCC 19606 and the clinical isolate TK1090) and Pseudomonas aeruginosa PAO-1 in C3H/HeN mice to evaluate the virulence of A. baumannii. Survival was evaluated over 14 days. At 1, 2, 5, or 14 days postinfection, mice of C3H/HeN were sacrificed, and histopathological analysis of lung specimens was also performed. Histopathological changes and accumulation of neutrophils and macrophages in the lungs after infection with A. baumannii and P. aeruginosa were analyzed. Following intratracheal inoculation, the lethality of ATCC 19606- and TK1090-infected mice was lower than that of PAO-1-infected mice. However, when mice were inoculated with a sub-lethal dose of A. baumannii, the lung bacterial burden remained in the mice until 14 days post-infection. Additionally, histopathological analysis revealed that macrophages infiltrated the lung foci of ATCC 19606-, TK1090-, and PAO-1-infected mice. Although neutrophils infiltrated the lung foci of ATCC 19606- and TK1090-infected mice, they poorly infiltrated the lung foci of PAO-1-infected mice. Accumulation of these cells in the lung foci of ATCC 19606- and TK1090-infected mice, but not PAO-1-infected mice, was observed for 14 days post-infection. These results suggest that A. baumannii is not completely eliminated despite the infiltration of immune cells in the lungs and that inflammation lasts for prolonged periods in the lungs. Further studies are required to understand the mechanism of A. baumannii infection, and novel drugs and vaccines should be developed to prevent A. baumannii infection.
Compact CPW-fed antenna with two asymmetric U-shaped strips for UWB communications

A novel coplanar waveguide (CPW)-fed printed antenna with two asymmetric U-shaped strips is designed and analysed for ultra-wideband wireless applications. The asymmetric radiating structure with two U-shaped strips and a staircase-shaped strip is adopted in the proposed antenna which broadens the bandwidth to a great extent. The dimensions of the antenna are only 23×25.5×1.6 mm. The antenna yields a wide bandwidth ranging from 3.0 to 12.9 GHz with return loss less than −10 dB with near-linear phase characteristics and stable antenna gain. Furthermore, the proposed antenna can achieve quasi-omnidirectional radiation patterns. The measured results agree well with the simulated prediction.
A correlation of capacitive RF-MEMS reliability to AlN dielectric film spontaneous polarization

This paper investigates the effect of spontaneous polarization of magnetron-sputtered aluminum nitride on the electrical properties and reliability of Radio Frequency – Micro-Electro-Mechanical Systems capacitive switches. The assessment is performed with the aid of application of thermally stimulated polarization currents in metal-insulator-metal capacitors and temperature dependence of device capacitance. The study reveals the presence of a surface charge, which is smaller than that expected from material spontaneous polarization, but definitely is responsible for the low degradation rate under certain bias polarization life tests.
BIONIC KNEES ALLOW OF SYMMETRICAL TEMPORAL-SPATIAL PARAMETERS OF GAIT COMPARED TO MECHANICALLY PASSIVE KNEE DESIGNS

The purpose of this study was to compare the basic temporal-spatial parameters of gait and gait symmetry in transfemoral amputees with a bionic knee joint with those in patients using a mechanically passive joint in relation to non-pathological gait. Seven subjects with a transfemoral amputation participated in this study. The amputee subjects performed fifteen attempts to walk across two Kistler force plates embedded in the floor. Objective gait measurements were acquired with a computerized video motion analysis system utilizing seven infrared cameras (Qualisys). Gait with a bionic knee joint showed greater symmetry than gait with a mechanically passive joint. When using a bionic knee joint, the stance and swing times approximated those in people without pathology.
The Cytotoxic Necrotizing Factors (CNFs)—A Family of Rho GTPase-Activating Bacterial Exotoxins

The cytotoxic necrotizing factors (CNFs) are a family of Rho GTPase-activating single-chain exotoxins that are produced by several Gram-negative pathogenic bacteria. Due to the pleiotropic activities of the targeted Rho GTPases, the CNFs trigger multiple signaling pathways and host cell processes with diverse functional consequences. They influence cytokinesis, tissue integrity, cell barriers, and cell death, as well as the induction of inflammatory and immune cell responses. This has an enormous influence on host–pathogen interactions and the severity of the infection. The present review provides a comprehensive insight into our current knowledge of the modular structure, cell entry mechanisms, and the mode of action of this class of toxins, and describes their influence on the cell, tissue/organ, and systems levels. In addition to their toxic functions, possibilities for their use as drug delivery tool and for therapeutic applications against important illnesses, including nervous system diseases and cancer, have also been identified and are discussed.
