PI Controlled Active Front End Super-Lift Converter with Ripple Free DC Link for Three Phase Induction Motor Drives

An active front end (AFE) is required for a three-phase induction motor (IM) fed by a voltage source inverter (VSI), because of the increasing need to derive quality current from the utility end without sacrificing the power factor (PF). This study investigates a proportional-plus-integral (PI) controller based AFE topology that uses a super-lift converter (SLC). The significance of the proposed SLC, which converts rectified AC supply to geometrically proceed ripple-free DC supply, is explained. Variations in several power quality parameters in the intended IM drive for 0% and 100% loading conditions are demonstrated. A simulation is conducted by using MATLAB/Simulink software, and a prototype is built with a field programmable gate array (FPGA) Spartan-6 processor. Simulation results are correlated with the experimental results obtained from a 0.5 HP IM drive prototype with speed feedback and a voltage/frequency (V/f) control strategy. The proposed AFE topology using SLC is suitable for three-phase IM drives, considering the supply end PF, the DC-link voltage and current, the total harmonic distortion (THD) in supply current, and the speed response of IM.
Impact of Demographic Characteristics on Job Satisfaction of Teachers in Pakistan: An Analysis

The main objective of the study is to study the impact of demographic variables on the job satisfaction of teachers. Bahawalnagar comprised the population of the study. 330 teachers were selected by using two stage sampling. At first stage schools were selected by using random sampling technique and at the second stage teachers were selected conveniently. For quantitative analysis, The tool of the study was “Teachers’ Job Satisfaction- Assessment Scale”, was adopted. Data were collected by using Google forms. The primary data were used and analyzed by descriptive and inferential statistics. The empirical finding suggests that there is a significant relationship between job satisfaction and demographic variables including gender, age, and nature of the entity. This paper also finds an evidence of bidirectional relationship between teachers’ performance and job satisfaction. It implies that working environment reinforces job satisfaction, and job satisfaction enhances working performance.
Predictive models for molten slags viscosity and electrical conductivity based on directed chemical bonds concept

The effect of the metallurgical slags composition on their physical properties was studied employing the Directed Chemical Bonds Concept (DCBC). It provides an effective concentration and convolution of the ab-initio information on the type of bonds in multicomponent systems. The predictive models for viscosity (lnη) and electrical conductivity (lnχ) of CaF2-Al2O3-CaO slag system have been built. Slag is a crucial part of various metallurgical processes. The electroslag remelting (ESR) is the best example because its efficiency and resulting ingot soundness strongly depend on slag properties. For the two slags (with 1.5 and 3% SiO2), the condition of stable homogeneous structure (activation energies ratio Eη/Eχ ≤1) has been satisfied in the widest temperature range (1513–1773 K) with a suitable viscosity (0.02–0.09 Pa∙s) and electrical conductivity (100–270 1/Ohm∙m). The DCBC makes it possible to move from the empirical selection to the target-oriented design of a proper slag with specific physical properties.
Aspectos biomecânicos da postura ereta: a relação entre o centro de massa e o centro de pressão

Biomechanics of standing posture: the relation between the center of mass and the center of pressure. The postural control is as complex as the movement control. Two biomechanical variables used to study postural control are the center of mass (COM) and the center of the forces applied in the support, the center of pressure (COP). The aim of this paper is to discuss the relation between these variables. The balance swing is the natural oscillation of the body during standing and is traditionally represented by COM displacement. The COP is related to postural control because it is due to the neuromuscular response to COM displacement. There are time domain and frequency domain differences between COM and COP. To control balance during standing, it is necessary to minimize the difference between COP and COM. The COM can be estimated by three procedures: kinematics, kinetics, and filtering. Acting as important variables for postural studies, COP and COM have different measurement procedures and different physical meaning, thus suggesting also different importance for balance control.
Taking a step back to move forward: understanding communication skills and their characteristics in the workplace

ABSTRACT Soft skills have been increasingly recognised as important in the workplace. They have been incorporated, moreover, in education and training curricula internationally. However, their conceptualisation lacks in theoretical grounding. This study fills this gap by taking a skills-utilisation approach (rather than a skills-requirements approach) and studying communication skills in the Human Resource function of two organisations, Flow and Energy. Key informants were participants in the events that were theoretically sampled (e.g. employees, candidates). Observations of interactions between HR professionals and their interlocutors, combined with conversations, interviews and organisational documents provided the data corpus. The analysis combined the key mechanics of grounded theory and discourse analysis. The conceptual framework drew on situated learning. Results indicate that communication skills should not be seen as decontextualised communication behaviours. Instead, communication skills require constant manoeuvring and alignment of communication behaviour (what people do) with the following three factors: the aim of the communication encounter, the actors’ positional identities and the various forms of knowing they bring to the practice. This view unveils the tentative and elusive (rather than transferrable and universally applicable) nature of communication skills. Such an evidence-driven conceptualisation has implications for how soft skills should be researched, understood and developed/accredited.
Designing acceptable user registration processes for e-services

User registration can have a serious impact on the success of online government services. Different services require different levels of identity assurance, and different registration processes are put in place to deliver them. But from the citizen’s perspective, these processes often require a disproportionate amount of effort, which reduces users’ acceptance. Typically, when sign-up to high-effort services is not mandatory, take-up is low; when it is compulsory, it causes resentment, and neither is desirable. Designers of services requiring registration currently have no way of assessing likely user acceptance at design time. We are introducing a tool that allows system designers to identify the impact of registration processes on different groups of users, in terms of workload and friction. Personas have been successfully applied to assist security designers, and we extend the concept with statistical properties, and introduce the Persona Group Calibration (PGC) exercise to calibrate the different personas for sensitivity to specific identity-related elements.
THE EFFECT OF LANDSIDE LENGTH ON TRACTOR FUEL CONSUMPTION AND DEPTH STABILITY OF MOLDBOARD PLOW

The moldboard plow is considered one of the most important implements used for plowing in Jordan, and the landside is considered one of the important plow parts which counteract the side pressure exerted by the furrow slice on the moldboard. For this reason, the experiments were conducted to study the effect of three speeds (5, 7 and 9 km/hr), three lengths of the front bottom landsides (20, 25 and 30 cm), and three lengths of the rear bottom landsides (20, 25 and 30 cm) on fuel consumption and depth stability of 2-bottom moldboard plow attached to 60 kW tractor working in sandy clay loam soil. The soil moisture content was approximately 10%. The plowing depth was adjusted at about 30 cm. Results showed that the fuel consumption was significantly (p<0.05)affected by the length of landsides and plowing speed. Minimum fuel consumption (12.60 l/ha) can be in conclusion obtained by using a 20 cm length for front bottom, and 25 cm length for rear bottom landsides, with 7 km/hr plowing speed, while the highest depth stability can be obtained by using 30 cm length of front and rear bottoms landside. In addition, the moldboard plow should not be used at a high speed, because that would increase fuel consumption, and negatively affect the depth stability.
Road, Traffic, and Human Factors of Pedestrian Crossing Behavior: Integrated Choice and Latent Variables Models

This study analyzed road, traffic, and human factors of pedestrian crossing behavior through the development of integrated choice and latent variables models. The analysis used recent research as a starting point, in which a two-stage approach was successfully tested, including a separate estimation of human factors and choice models. Data from a dedicated field survey were used: pedestrian field observations of road crossing behavior in different road and traffic scenarios were combined with a questionnaire on pedestrian attitudes, perceptions, motivations, and declared behaviors. The integrated choice and latent variables models were developed for four road types: major urban arterials, main roads, secondary roads, and residential roads. Results suggest that the effect of traffic conditions on pedestrian crossing choices was more important on main and secondary urban roads, whereas on major urban arterials and on residential roads it was nonsignificant. In regard to the effects of human factors, a risk latent variable was found to enhance the explanatory power of most of the models. This variable was estimated on the basis of different indicators in each case, reflecting a clear risk-taking tendency on major and main roads and an optimization tendency on minor roads. Overall, it is indicated that the integration of human factors in pedestrian crossing models provides meaningful and insightful results, and they may be advantageous compared with the two-stage approach.
LTE Synchronization Algorithms

Third Generation Partnership Project (3GPP) Long Term Evolution(LTE) provides high spectral effciency, high peak data rates and frequency exibility with low latency and low cost. Usage of modulation techniques like OFDMA and SCFDMA enables LTE to achieve such requirements.However it is well known that OFDM systems like LTE are very sensitive when it comes to carrier frequency off- sets and symbol synchronization errors.Inorder to transfer data correctly, the User Equipment(UE) must perform both uplink and downlink synchronization with the Base station(eNodeB). In this thesis, Primary Synchronization Signal(PSS) and Secondary Synchronization signal(SSS) are used to detect the cell-ID of the best serving base station and also to achieve downlink synchronization whereas Physical Random Access Channel(PRACH) preamble is used to obtain uplink synchronization. PSS and SSS helps to achieve downlink synchronization by estimating the frame timing and carrier frequency offsets.In this thesis a non-coherent detection approach is followed for detection of both PSS and SSS signals.

The impact of building information modeling (BIM) to architectural design process

Design in architecture is one of the most diverse activities considered by all related parties in construction industry. During the construction design process, many problems and errors such as design changes & rework, incomplete design, standard of quality in drawings and technical specifications, lack of communication, delays in the drawings, mistakes and errors are arising from this industry day by day. This research has been conducted with the aim to establish the contribution of Building Information modeling (BIM) on architectural design process. The objectives of this research includes, to recognize and examine the current conventional design problems in construction projects in terms of time, cost and quality and to recommend the benefit that is obtained by using BIM technology in the architectural design process. This research was conducted by using qualitative method where experience architects whom are currently implementing BIM in their firms was been interviewed. The feedback and results obtained from the interview were analyzed by using Microsoft Excel. Quota sampling method was used in selecting the respondents, which consists of 8 architects implementing BIM. The analysis results shows that, architect realize the problems and suggested the solutions based on their experience in handling several of projects by using the conventional method. It also shows that, BIM is the future tools for 3D design since it integrate all the design documents, the drawing are well interpreted and the designer easily viewable compared to conventional method. It is important, architects need to present their design in 3D drafting to create a better visualization to the client. Adoption of BIM should be implemented from the early process in order to manage construction project effectiveness.
Relationship between Rotating Night Shift and Lipid Profile in Minia mills, Egypt

Background: The advent of the 24 hour society has resulted in a need for greater flexibility in working time patterns and, in many cases, an increase in night working. In the twentieth century, night working was associated with manufacturing in larger plants where three eight hour shifts tended to be a typical pattern with full time employees alternating between early, middle and late shifts. hift work exerts major influences on the physiological functions of the human body. Several studies have suggested that rotating night shift work is associated with an increased risk of obesity and metabolic syndrome. This study investigated the relationship between shift work and lipid profile. Aim of the study: to identify whether rotating shift workers are more prone to dyslipidemia than day shift workers in Minia mills. Subjects and methods: This is a descriptive cross-sectional study which carried out in Minia mills, Egypt, during the period from September 2018 to March 2019. This study was conducted among 107 workers who were agreed to be interviewed and participate in this study. Data were collected by a questionnaire included demographic data, anthropometric measurements and laboratory tests were performed. Results: This study found higher levels of all components of lipid profile (Total cholesterol, HDL and LDL) among shift workers compared to day workers but without statistical significance. Regarding LDL ≥130 mg/dl, percentage of rotating shift workers with LDL ≥130 mg/dl was significantly higher than percentage of daytime workers (34.5% compared to 15.4%), and the percentage of persons had TG ≥ 150mg/dl was significantly higher among shift workers, where 90.9% of them had TG ≥ 150mg/dl compared to 62.3% of day time workers (p=0.001). Conclusion: Shift work was associated with lipid profile disorders in Minia mills. Recommendation: Health system programs especially designed for shift-workers, including diet and exercise, must be stressed and regularly assessed.
Routing protocol berbasis cluster segitiga

Wireless sensor networks users are increasing drastically in communication and technology. They consist of small battery powered devices with limited energy resources. Once deployed, the small sensor nodes are usually inaccessible to the user, and thus replacement of the energy source is not feasible. However, the smaller of a device the better it is. The development of device should be user friendly. Hence, energy efficiency is a key design issue that needs to be enhanced in order to improve the life span of the network. In BCDCP, all sensors send data from CH (Cluster Head) and then to BS (Base Station). BCDCP works well in small-scale network but in large scale network it is not appropriated since it uses much energy for long distance wireless communication. We propose a routing protocol - Triangular Clustering Routing Protocol (TCRP) - to prolong network life time through the balanced energy consumption. RPTC selects cluster head of triangular shape. The sensor field is divided into energy level and in every level we choose one node as a gate node. This gate node collects data and sends it to the leader node. Finally the leader node sends the aggregated data to the BS. We show TCRP outperforms BCDCP with several experiments. Key words: Wireless Sensor Network, Routing Protocol, Clustering
Electrocardiographic characteristics of significant factors of detected atrial fibrillation using WEMS

The wireless electrocardiographic monitoring system(WDMS) is designed to be long term monitoring for the early detection of cardiac disorders. The current version of the WDMS can identify two types of cardiac rhythms in real-time, such as atrial fibrillation(AF) and normal sinus rhythm(NSR), which are very important to track cardiac-rhythm disorders. In this study, we proposed the analysis method to discriminate the characteristics statistically evaluated in both time and frequency domains between AF and NSR using various parameters in the heart rate variability(HRV). And we applied various ECG detection methods (e.g., difference operation method) and compared the results with those of the discrete wavelet transform(DWT) method. From the statistically results, we found that the parameters such as STD RR, STD HR, RMSSD, NN50, pNN50, RR Trian, and TNN(p<0.05) are significantly different between the AF and NSR patients in time domain. On the other hand, the frequency domain analysis results showed a significant difference in VLF power(ms²), LF power(ms²), HF power(ms²), VLF(%), LF(%), and HF(%). In particular, the parameters such as STD RR, RMSSD, NN50, pNN50, VLF power, LF power and HF power were considered as the most useful parameters in both AF and NSR patient groups. Our proposed method can be efficiently applied to early detection of abnormal conditions and prevent the such abnormals from becoming serious.

Combining Resource Based and Evolutionary Theory: A Synthesis Applied to Bio-Enterprise Networks

This paper explores ways in which new ventures not only adapt to but can transform their own business environment. It proposes a new way to combine evolutionary and Penrosian resource-based theories. A parallel is drawn between the proactive response to resource shortfalls and under-use in the Penrosian firm and the way entrepreneurial participants in innovative networks can build complementary capability. Two case studies of biopharm ventures show how participants cumulatively altered prevailing business conditions and selection processes. The approach shows how evolutionary theory can be used to identify overlooked connections and clarify overlooked causal processes that have collective effects. How entrepreneurial activity lays the basis for further innovation is revealed by an analysis with the wider potential to bridge evolutionary and resource based approaches.

Mirror symmetry for the Tate curve via tropical and log corals

We introduce tropical corals, balanced trees in a half‐space, and show that they correspond to holomorphic polygons capturing the product rule in Lagrangian Floer theory for the elliptic curve. We then prove a correspondence theorem equating counts of tropical corals to punctured log Gromov–Witten invariants of the Tate curve. This implies that the homogeneous coordinate ring of the mirror to the Tate curve is isomorphic to the degree‐zero part of symplectic cohomology, confirming a prediction of homological mirror symmetry.
An Analysis on Students Ideas about English and Urdu as Medium of Instructions in the Subjects of Social Sciences studying in the Colleges of the Punjab, Pakistan

1. Director Public Instruction (Colleges), Higher Education Department, Lahore, Punjab, Pakistan 2. Assistant Professor, Department of Urdu, Govt. Islamia Graduate College for Women, Lahore, Punjab, Pakistan PAPER INFO ABSTRACT Received: October 07, 2021 Accepted: December 29, 2021 Online: December 31, 2021 The worth and usefulness of English education as a foreign language is of great concern to language rule and planning (LRP) researchers compared to teaching their native language globally in higher education. The study under research examines the perspectives of two similar groups of the final year students of at Higher Education Institutions of Pakistan. The first group consists of art students who received the Urdu medium of instruction (UMI), and the second group received the English medium of instruction (EMI). An empirical methodology was carried out in the present year, students answered questionnaires to find out the benefits and challenges of learning subject-based knowledge, what subject-based knowledge means to them, and their understanding of language as a teaching language. Interviews were conducted with the selected group of students who wished to participate in research. Additional information is available from the tests and results obtained in the two equivalent courses. Although many similarities have been identified between the two groups, the overall knowledge of disciplinary knowledge of English medium instruction students was not very effective, while that of UMI students was very effective. It explains the implications of the findings to continue the language rule as policy experience for teaching in higher education institutions.
