Measurement of Real Time Energy Consumption using Low-Cost High-Speed Microcontroller

Consumption of energy is increasing day-by-day and consequently, its control has become indispensable, that triggered adoption of various techniques by researchers for reliable solution. This proposed work investigates a simpler design of energy estimation along with unit consumption using low-cost high-speed microcontroller, which is carried out both with linear and non-linear loads. In the absence of a standard digital energy meter, a theoretical approach has been taken into consideration to calculate the measurement of percentage error. Though the unit consumption defines 1 kWh usage of energy, this proposed work has been implemented with a single unit equivalent to 10 Watt-hour energy consumption to read the data within a lesser time. The percentage error has been found to be within an acceptable range of ±2%.
Decentralized Stability Conditions in DC Microgrids

We consider the problem of ensuring stability in a DC microgrid by means of decentralized conditions. Such conditions are derived which are formulated as input-output properties of locally defined subsystems. These follow from various decompositions of the microgrid and corresponding properties of the resulting representations. It is shown that these stability conditions can be combined together by means of appropriate homotopy arguments, thus reducing the conservatism relative to more conventional decentralized approaches that often rely on a passivation of the bus dynamics. Examples are presented to demonstrate the applicability and the efficiency of the results derived.
Discrete-Time Implementation of an Adaptive Gain First-Order Sliding Mode Control Law

A discrete-time implementation of a continuous-time adaptive gain sliding mode control law for a system with matched disturbance is presented. The discrete-time control algorithm is derived from the solution of the nominal continuous-time closed-loop dynamics. This approach ensures elimination of discretization chattering as well as proper disturbance rejection. Slight modifications of the resulting discrete-time control law are proposed to guarantee ultimate boundedness of the sliding variable and the adaptive gain which is formally proven by means of Lyapunov arguments. Prevention of discretization chattering and disturbance attenuation properties are validated in a simulation and compared to other approaches.
Deep Learning for Hardware-Impaired Wireless Secret Key Generation with Man-in-the-Middle Attacks

Wireless secret key generation (WSKG) allows efficient key agreement protocols for securing the sixth generation (6G) wireless networks. Nevertheless, due to external adversaries or internal impairments, WSKG schemes might become vulner-able during the randomness distillation, where the legitimate nodes try to observe their source of common randomness. In this paper, we investigate the WSKG scheme with legitimate parties suffering from hardware impairments (HIs), while an active adversary acts as a man-in-the-middle (MiM) via injecting fake pilot signals. We first utilize randomized pilots to overcome the MiM. We also leverage the concept of recurrent neural networks (RNNs) to further enhance the randomness distillation. More specifically, the long short-term memory networks (LSTMs)-as a well-established type of RNNs-are implemented to learn the long-term dependencies between the observations of legitimate parties. The achievable secret key rate (SKR) and the impact of MiM on system's performance are analyzed. Our numerical results verify the performance gain of our proposed learning-based approach compared with the state-of-the-art methods and provide useful insights on system design. We show that our RNN-based approach achieves 30% and 15% improvement in terms of observation mismatches compared with the naïve scheme and the fully-connected benchmarks, respectively.
People’s experiences of distress and psychosocial care following a terrorist attack: interviews with survivors of the Manchester Arena bombing in 2017

Background Distress after major incidents is widespread among survivors. The great majority do not meet the criteria for mental health disorders and rely on psychosocial care provided by their informal networks and official response services. There is a need to better understand their experiences of distress and psychosocial care needs. Aims The aims of our study were to enhance understanding of the experience of distress among people present at the Manchester Arena bombing in 2017, identify their experiences of psychosocial care after the incident and learn how to better deliver and target effective psychosocial care following major incidents. Method We conducted a thematic analysis of semi-structured interviews with 18 physically non-injured survivors of the Manchester Arena attack, who registered with the NHS Manchester Resilience Hub. Results Distress was ubiquitous, with long-lasting health and social consequences. Initial reluctance to seek help from services was also common. Early and open access to authoritative sources of information and emotional support, and organised events for survivors, were viewed as helpful interventions. Inappropriate forms of psychosocial and mental healthcare were common and potent stressors that affected coping and recovery. Conclusions This paper extends our understanding of how people react to major events. Provision for the large group of people who are distressed and require psychosocial care may be inadequate after many incidents. There is a substantial agenda for developing awareness of people's needs for psychosocial interventions, and training practitioners to deliver them. The findings have substantial implications for policy and service design.
Experimental investigation on a 200K/40W free-piston Stirling cooler

A high capacity free piston Stirling cooler(FPSC) was designed for 200 K low-temperature fridge.In order to study the characters of the prototype,a performance test bench was built.Frequency characteristics of the compressor and the expander were investigated in detail.The effects of charged pressure and cooling temperature on the compressor resonance frequency were tested.Furthermore,the influences of the displacement phase shift and the expander natural frequency on its operating frequency were experimentally studied.The static loss of the cooler was tested by multipoint hot load static rewarming method.The helium and the mesh screens are proved to have little affection on the static loss in virtue of thermal conduction.The maximum cooling capacity of the prototype can reach 40 W at 200 K with 250 W input.
Comparison of empirical liquefaction potential evaluation methods

Numerous methods exist to determine the liquefaction potential of a site due to earthquake, from which the stress-based empirical methods are the most commonly used in practice. Despite of their widespread use, their shortcomings have given way to the evolution of strain and energy-based methods. Their benefits make them a very promising alternative candidate for liquefaction potential evaluation. To reveal differences and uncertainties involved in the different methods, a comparative analysis was performed for the site of the Paks Nuclear Power Plant with the aim of contributing to the safety assessment of the plant with respect to liquefaction effects.
Improved higher lead time river flow forecasts using sequential neural network with error updating

Abstract This paper presents a novel framework to use artificial neural network (ANN) for accurate forecasting of river flows at higher lead times. The proposed model, termed as sequential ANN (SANN), is based on the heuristic that a mechanism that provides an accurate representation of physical condition of the basin at the time of forecast, in terms of input information to ANNs at higher lead time, helps improve the forecast accuracy. In SANN, a series of ANNs are connected sequentially to extend the lead time of forecast, each of them taking a forecast value from an immediate preceding network as input. The output of each network is modified by adding an expected value of error so that the residual variance of the forecast series is minimized. The applicability of SANN in hydrological forecasting is illustrated through three case examples: a hypothetical time series, daily river flow forecasting of Kentucky River, USA and hourly river flow forecasting of Kolar River, India. The results demonstrate that SANN is capable of providing accurate forecasts up to 8 steps ahead. A very close fit (>94% efficiency) was obtained between computed and observed flows up to 1 hour in advance for all the cases, and the deterioration in fit was not significant as the forecast lead time increased (92% at 8 steps ahead). The results show that SANN performs much better than traditional ANN models in extending the forecast lead time, suggesting that it can be effectively employed in developing flood management measures.
Acoustic Wind Tunnel Measurements of a Quadcopter in Hover and Forward Flight Conditions

An experimental testing campaign was conducted in the NASA Langley Low Speed Aeroacoustic Wind Tunnel (LSAWT) in order to better understand the acoustic characteristics of a representative quadcopter system in both hover and forward flight conditions. Aerodynamic performance measurements were acquired using a multi-axis load cell to trim the vehicle to desired thrust/lift conditions. Hover acoustic measurements provide evidence of prominent rotor-airframe interaction noise that manifests in the form of high-amplitude harmonics of the fundamental rotor blade passage frequency. Forward flight acoustic measurements of simultaneous rotor operations indicate the presence of strong forward-aft rotor wake interactions that yield increased broadband noise levels relative to cases of individual rotor operation. These results indicate the potential need for modeling complex noise generation mechanisms associated with multirotor and rotor-airframe interactions for vehicles of this class.
Sulforaphane pre-treatment improves macrophage killing

Binge drinking is associated with increased mortality and morbidity. Burkholderia pseudomallei, the causative agent of pneumonic melioidosis can occur in healthy humans; however, binge alcohol intoxication is a major risk factor. Previous findings indicate that a single binge alcohol episode increases Burkholderia spp. infection by reducing alveolar macrophage function. The aim of this study was to test the ability of the phytonutrient sulforaphane (SFN) to rescue the phagocytic function of alveolar macrophages when infected with Burkholderia spp. in vitro. B. thailandensis E264 was used as a useful BSL-1 model to determine the effects of SFN pre-treatment. The primary outcome was macrophage phagocytic killing, while the secondary outcome was the nuclear factor (erythroidderived 2)-like (Nrf2) signaling response measured by western blot analysis. Results indicate that alveolar macrophages pre-treated with SFN (5 M) and challenged with 0.2% (v/v) alcohol for 3 or 8 h prior to live B. thailandensis infection improved intracellular killing of B. thailandensis ~2-fold compared to MH-S cells treated with alcohol alone. These data demonstrate that SFN may be an effective pre-treatment option to prevent alcohol mediated immune dysfunction and restore macrophage phagocytic killing of Burkholderia spp. and other similar opportunistic pathogens.
FashionSupplyChainOptimization:ALinearProgramming Model

Fashion supply chain management is challenging due to demand uncertainty, short product life cycle, fierce global competition, increasing expectations for diversity in production, and keeping pace with the current and emerging trends. In this paper, a brief review of the published works in the field of fashion and clothing supply chain is presented and an integrated linear model is developed to minimize the costs of a fashion brand, including production and logistics costs, enabling the firm to make better decisions with regard to its production and replenishment policies and to respond in a reasonable time to customers demands for various designed items. We show that our model can successfully account for the complex structure of the supply chain consisting of designers, manufacturers, distributors, and stores. The model is validated using the General Algebraic Modeling System (GAMS) with the data collected from an Iranian fashion brand.

Recognizing, as does Dr. Meyer, the socio-economic forces that foster bigotry and deprivation, he defines the professional function of the counselor and presents a design for training the kind of guidance specialists who can nurture human health and thus control the sickness of illwill.
American Communities

The metropolis rises with increasing prominence against the social landscape of western civilization, especially in the United States. The penetration of metropolitan influence into all the recesses of Social structure and the diffusion of those ways of life which it nurtures confound the efforts of anyone who seeks to identify "the community" in American life. The population of the United States increased 14.5 per cent during the forties; but that of metropolitan areas (including center and suburb), 21 per cent; and that of all other places, only 5.7 per cent. The rate of growth at the metropolitan periphery (35 per cent) was nearly three times that at the center (13 per cent), but continuing metropolitan agglomeration of population was evident to the point of being dramatic. Various positions of reason and sentiment may be taken in viewing this population trend and the probabilities of its termination or continuance. Its present and foreseeable impacts will continue to rest heavily against the shape and function of all our personal, social, and cultural systems. The complexity of social structures and processes, t h e diversity of their interdependent parts and directions, and the swallowing up of small things by large ones--all these baffle the earnest citizen who wishes to know and to serve his "community. " Nor can he resolve his confusion merely by moving as far as possible from centers of concentration to areas of sparser settlement, whether to smaller cities, to the hills, or to the plains.

Therefore, this paper contributes the strategic approach to preserving the integrity of halal while sustain the firm performance.
A Retrospective Study to Evaluate the Effect of Dynamic Fracture Mobility on Cement Leakage in Percutaneous Vertebroplasty and Percutaneous Kyphoplasty in 286 Patients with Osteoporotic Vertebral Compression Fractures

Background Cement leakage is the most common complication following percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fractures (OVCFs). Dynamic fracture mobility was determined by comparing preoperative standing lateral radiographs with intraoperative prone lateral radiographs. This retrospective study from a single center aimed to evaluate the effect of dynamic fracture mobility on cement leakage in PVP and PKP in 286 patients with OVCFs. Material/Methods Records of patients who underwent PVP or PKP in our department between January 2016 and December 2019 were retrospectively analyzed, showing that 156 patients received PVP and 130 patients received PKP. Variables that were significantly related to presence of cement leakage in the univariate analysis were subsequently included in a multivariate logistic regression analysis for determining the independent risk factors for cement leakage. Results The univariate analysis showed that dynamic fracture mobility (P<0.001), operative approach (P=0.026), peripheral vertebrae wall damage (P<0.001), intravertebral cleft (P<0.001), and cement volume injected (P<0.001) were correlated with cement leakage. Factors that showed differences by univariate analysis underwent multivariate logistic regression analysis, showing that peripheral vertebrae wall damage (OR=11.774,95% CI 4.384–31.619, P=0.000), dynamic fracture mobility (OR=5.884, 95% CI 2.295–15.087, P=0.000), operative approach (OR=3.143, 95% CI 1.136–8.698, P=0.027), and cement volume injected (OR=1.486, 95% CI 1.119–1.973, P=0.006) were independent risk factors for postoperative cement leakage. Conclusions This retrospective study showed that dynamic fracture mobility, peripheral vertebrae wall damage, operative approach, and cement volume injected were risk factors for cement leak following PVP and PKP.
Prevalence and determinants of latent tuberculosis infection among healthcare personnel in India: A scoping review

Introduction: Health personnel in high-burden countries are at a greater risk of tuberculosis (TB) infection, due to continuous exposure to diagnosed and undiagnosed pulmonary TB cases. A scoping review is done to ascertain the prevalence and risk factors for latent TB infection (LTBI) among India's healthcare personnel. Materials and Methods: A review of literature was done from Medline, CINAHL, Global Health and PubMed. Full-text review of 30 articles was done, and three were found to be eligible for final analysis. Results: The prevalence of LTBI was found to range from a quarter to one-third of the study participants. Available evidence has revealed the role of increased time being spent in the healthcare profession as an essential risk factor for the development of LTBI. The study participants were of younger age in all studies. There was a lack of representation of different categories of health workers. Discussion: Higher prevalence in younger participants poses significant threats to the well-being of healthcare professionals. The absence of proper guidelines for treating LTBI in high-prevalent settings and the lack of awareness among healthcare professionals regarding LTBI are significant challenges for preventing TB infection among healthcare professionals.
Current Issues in the Education of Teachers

The number of important issues in the education of teachers is so large that those selected for discussion here represent only a small fraction of those meriting treatment. On the other hand, although the present choice of issues is inevitably personal rather than defensibly representative, we have tried to select questions that seem to us to be of primary rather than secondary importance. The major topics treated include: (a) the relation of the public esteem of teachers to the learning of their students; (b) the tremendous disparity between what the novice t~acher needs from his preservice education and the time allocated for it; (c) educational theory and practice and in-service education; (d) the importance of in-service education; and (e) the teacher as person.
Towards Team Engagement Through Team Empowerment: Moderating Roles of Team Reflexivity and Team Orientation

The article investigates the role of team empowerment in enhancing team engagement by collecting data from 33 teams comprising of 330 individuals from IT/IT-enabled services (ITES) organizations belonging to the Delhi-NCR region of northern India. The research findings established a positive association between team empowerment and team engagement, as was hypothesized. Team reflexivity and team orientation moderated the association between team empowerment and team engagement. The study draws the attention of management towards designing their vision and mission in such a manner that the employees take ownership and feel a sense of pride in being a part of the organization. Perceptions about team oriented behaviour and team reflexivity will help the employees, in particular, and the organizations, in general, compete in the journey towards excellence. Not much evidences to study team empowerment, specifically in the context of virtual teams, and its beneficial outcomes have been found in literature in Asian milieu. In this context, this is a significant and critical attempt to investigate the linkages between team empowerment and teamwork engagement and any moderating role of team reflexivity and team orientation in the above stated relationship.
Seroprevalence of HBV Infection in a Tertiary Care Hospital in Bangladesh

An estimated 1 million people die each year from HBV infection. This investigation aimed to determine the frequency, distribution, and risk factors for HBV infection in a healthy Bangladeshi community. A cross-sectional study among the general population was conducted in Dhaka Medical College Hospital. A series of 100 patients with the chronic liver disease between 18 to 49 years. Diagnosed based on clinical and biochemical parameters were collected. All medicine units of Dhaka Medical College Hospital have been analyzed regarding the seroprevalence of HBsAg and its correlation with the demographic pattern. Among 100 cases of liver disease, the number of CLD patients was 85, of which 56 (65.88%) were HBsAg positive 29 (34.11%) were HBsAg negative. The number of patients with acute viral hepatitis was 15, of which 4(26.66%) were HBsAg positive, 11(73.33%) were HBsAg negative, and the overall seroprevalence was 60%. The age incidence was more below 40 years (83%) less above the age of 40(17%). Males had higher seropositivity (70.31%) than females (41.66%). People of all ages are susceptible, particularly the farmers (21.66%) and manual laborers (13.33%). Most of the patients belong to the poor (62.79%) and middle class (62.22%). Urban people were more (60.93%) susceptible than rural people (58.33%). Married persons were more (70.27%) prone than unmarried (30.76%). Seroprevalence of HBsAg was more in those people who had a history of blood and blood product transfusion (84.61%). Illiterate persons were more (75%) susceptible than literate (59.37%). Seroprevalence of HBsAg was more in those who had a history of instrumental tooth extraction (68.42%) than those who had not (58.02%). People who cut their beards and mustache in the barbershop were more susceptible (73.91%) than those who got it by themselves (68.29%). Among female persons, those who underwent instrumental delivery were more susceptible than those who delivered their baby by normal vaginal delivery.
