Automation of power systems is gaining momentum across the world, and there is a need to expose graduate and undergraduate students to the latest developments in hardware, software, and related protocols for power automation. This paper presents the design, development, and commissioning of an automation lab to facilitate the understanding of substation automation (SA). The laboratory has relay intelligent electronic devices (IEDs) that support IEC 61850 protocol, a universal secondary test kit for testing the relays, a protocol converter that can be programmed and can handle a large number of power automation protocols, a Global Positioning Systems (GPS) clock for time synchronization, and all related software. In this paper, the retrofitting of the latest relay IEDs with the existing control center software has been demonstrated. The commissioning process and the experimental setup of the SA laboratory have also been described. A post-training evaluation emphasizes that the student learning experience is helping students to gain a better understanding of the theory and to have better career prospects in power automation. The SA laboratory, which demonstrates all aspects of substation automation, is being used extensively for research and training in this emerging field. (Contains 7 figures.)

In the country presently, preclinical medical students are not routinely exposed to real patients. Thus, when they start clinical postings, they are found to have poor clinical reasoning skills. Simulated virtual patients (SVPs) can improve clinical skills without endangering real patients. This pilot study describes the development of two SVPs in endocrine physiology and their validation in terms of acquisition of clinical knowledge and student engagement. Two SVPs, Nandini Sharma (unintentional weight gain) and Sunil Yadav (polyuria), were created and published on the i-Human Patients platform through an iterative, interdisciplinary, and transdisciplinary collaborative process using the conceptual framework of Kim et al. (Kim, S., Phillips, W. R., Pinsky, L., Brock, D., Phillips, K., Keary, J. "Med Educ" 40: 867-876, 2006). After internal and external peer validation, the SVPs were piloted on 40 students (20 students per virtual patient) over 2 wk. A cognitive pretest was conducted before exposure, and a posttest soon after. Faculty and student feedback were collected. Faculty found SVPs authentic, helpful as teaching-learning tools, and useful for giving feedback and for assessment. Students found SVPs more engaging than paper cases and helpful in developing clinical reasoning and in imparting clinical exposure. Pretest and posttest scores indicated knowledge gain (P<0.01). Although challenging to create, SVPs created on the i-Human Patients platform improved learning in endocrine physiology and were well accepted by students and faculty as a means to provide early clinical exposure. More SVPs can be developed through collaboration between stakeholder departments and integrated into the curriculum for greater benefit.

Online monitoring of high-voltage (HV) equipment is a vital tool for early detection of insulation failure. Most insulation failures are caused by partial discharges (PDs) inside the HV equipment. Because of the very high cost of establishing HV equipment facility and the limitations of electromagnetic interference-screened laboratories, only a few educational and research institutes have facilities to carry out PD research studies. A remotely operated HV laboratory, i.e., the Virtual Instrumentation and Information and Communication Technologies (VI-ICT) facility, has been created to raise interest among students, researchers, and industrial users in the hands-on experimentation of PD activity inside HV power equipment. This paper describes the approaches to and mechanism for hands-on experimentation in PD detection and measurement and how this is conducted remotely using the facility. This remotely operated HVPD laboratory, as well as hosting the HV laboratory course, can provide training and testing for industry and utilities around the world.

In the past few years many choreographers have focused upon implementation of computer technology to enhance their artistic skills. Computer vision technology presents new methods for learning, instructing, developing, and assessing physical movements as well as provides scope to expand dance resources and rediscover the learning process. This work reviews the study done over AR based learning technologies for the development of inter personal skills. This paper further elaborates the literature done till date within the scope of AR based training for educational aspects. The review focuses on the techniques categorized according to the type of dance learning method which can further be enhanced and addressed by means of novel AR based technology. The authors aim to provide an overview for learning standards based on AR Kinect sensors. In addition the future work is toward exploring the latest version of Kinect V2 for dance training that could become the next futuristic virtual educator.

Over the past decade, industry relevance and connectedness have evolved into a key requirement for students and their parents, who increasingly perceive employability upon graduation as a critical factor in the degree selection process. Simultaneously, professional bodies emphasise the need for high levels of industry engagement as a condition for accreditation, which in turn further impacts on the "marketability" of a specific degree. However, many of the skills emphasised by potential employers and industry reference groups are more closely aligned with generic graduate attributes, rather than discipline specific knowledge and skills. This increasingly includes an emphasis on cultural awareness, excellent communication skills and the ability to work in dispersed, often even virtual teams. This observation is arguably particularly relevant within the business (degree) context, where workforces become increasingly multicultural, as traditional borders and limitations make way for transnational opportunities. This paper discusses the benefits and challenges associated with a third year student project that set out to combine the need for discipline specific knowledge, with the acquisition of versatile, culturally sensitive business skills. Students participating in the aptly titled "communications challenge" competed against their peers as part of multicultural teams, representing twelve countries, across five continents. The authors conclude that experiential learning opportunities like this global, real life client project may not necessarily be popular amongst the wider student cohort. Furthermore, the acquisition of discipline specific knowledge may be limited when compared to "traditional" teaching deliveries. However, projects like this provide a number of benefits, in particular in the context of capstone units that set out to prepare students for a diverse career in an increasingly global, multicultural and complex environment.

A comprehensive survey on the Internet based virtualisation of experiments is presented, covering several individual as well as collaborative efforts in various engineering disciplines. From this survey it could be concluded that there is a pressing need to develop full-fledged remote laboratory experiments for integrated directly into engineering curricula. The paper subsequently summarises the experiences of authors during the design, evolution and implementation of virtualisation for a number of engineering experiments, enabling these to be accessed through the Internet as virtual experiments. It also covers the features required to give the "feel" of performing experiments, inclusion of learning components, incorporation of easy navigation, testing of effectiveness of learning, and development of useful feedback mechanisms. A detailed feedback analysis from prospective learners is presented on the effectiveness of the virtual laboratory.

In the high pressure applications, safety and handling of the design parts are crucial and essentially required. If the design parameters are not properly optimized, sometimes it leads to fatal accidents or huge money loss. With the advent of modern computational tools, the simulation based design analysis is now a day's address above issues amicably to ultimately helping to improve development process and final product. The paper describes the step by step design process and simulation analysis of the pressure chamber. The theoretical FEA studies carried out on the designed pressure cell show that the chamber is working smoothly within the desired pressure range from atmospherics pressure to 200 MPa based on safety factor of the material used. Such devices are mostly imported and not available indigenously. Thus, the fabrication of simulated device is one step forward to develop an import substitute item and promote 'Make in India' product. Simulated results are found to quite encouraging. The actual experiments on the fabricated pressure cell would be performed in due course of time. [ABSTRACT FROM AUTHOR]

The paper highlights the implications of Goods and Services Tax (GST), a major tax reform in India launched in July 2017 on the Make in India initiative launched in the year 2014. The GST is expected to trigger its impact on the following eight elements: warehouse efficiency, interstate check‐post operations, informal to formal business transition, interstate business expansion by micro, small, and medium enterprises, simplicity and transparency in tax collection process, logistics cost reductions, ease of doing business in India, and working capital cost realignment, which in turn may accelerate the manufacturing growth in Indian economy. In order to study the impact of the factors of GST on the Make in India initiative and the manufacturing growth, a system dynamics approach has been adopted in this paper. A number of simulation runs carried out using the system dynamics modelling have provided meaningful insights to the policymakers and strategic planners for evolving strategies for manufacturing growth.

Background & Objective: There is an increasing demand for computer aided instruments in medicine to assist doctors and technicians. This paper presents a simulation of skeletal model of human upper extremity, which monitors position, orientation, trajectory, force and torque generated by upper limb movement. Materials and Methods: An artificial upper limb model is prepared with servo motors and aluminium T- section which moves in 2D vertical XY plane and whose control is through PC through user friendly software. In first phase: Values of time, power and torque were estimated for each joint after making the robot-model move in flexion and extension with different weights. In second phase: same values were estimated after strapping subjects arm and making the robot-model move in flexion and extension. Results: Values of Power and Time taken by joints to lift weight at different speeds showed that torque and power are higher for higher flexion angle as well as higher load value. Experimental values for flexion of wrist (p<0.05), elbow (p<0.01), shoulder (p<0.05) with subjects, showed that time taken by elbow was lesser than that taken by wrist and time taken by shoulder was still lesser than elbow for same amount of weight lifted. Results considering force sensor showed that motor torque rises when load is lifted against gravity. Conclusion: This model could be used as a tool in neuromuscular disorders for enhancing the functionality of robot assisted upper limb therapy and data from model could help the therapist to know about actual resistance force at each joint and quality of exercise trajectory achieved by each subject.

Abstract: A lecture theatre with dimension 16m×8.4m×3.6m located at Roorkee (28.58°N, 77.20°E) in the northern region of India, is selected to calculate the monthly and annual cooling load (kWh) and cooling capacity of air conditioning system by a computer simulation. The paper also presents the results of a study investigating the effect of different glazing systems on windows and the reduction in building cooling load. DesignBuilder software has been used for the computer simulation for calculating the cooling load. The paper aims to investigate the reduction in thermal gains and cooling load requirements by varying the U-values of different glazing types, insulating the ceiling, providing cool roofs, interior and exterior insulation on walls, and replacing the conventional fluorescent tube lamp (FTL) by energy efficient compact fluorescent lamp (CFL). Installation of false ceiling, wall insulation, different glazing types and lighting systems are cost effective with normalized annual saving ranging from 17% to 19.8% from this retrofitting project. Furthermore, the study also highlights the potential of reducing the emission of CO2 and equivalent carbon credit. Retrofitting techniques strongly influence the level of energy saving, although the payback period is generally quite long of order 8years. [Copyright &y& Elsevier]

Analysis of pre-monsoon convective systems over the southern peninsular India has been performed using C-band radar and numerical simulation. Statistics on the radar polarimetric measurements show that the distribution of differential reflectivity (Zdr) and specific differential phase (Kdp) have much higher spread over convective regions. The distribution of Kdp is almost uniform across the vertical over the stratiform regions. The mean profile of Zdr over stratiform regions shows a distinct local maxima near melting level. A comprehensive analysis has been done on an isolated deep convective system on 13 May 2018. Plan position indicator (PPI) diagrams and satellite measured cloud top temperature demonstrate that pre-monsoon deep convective systems can develop very rapidly within a very short span of time over the region. Heavy precipitation near the surface is reflected in the high value of Kdp (>5° km−1). High values of Zdr (>3 dB) were measured at lower levels indicating the oblate shape of bigger raindrops. A fuzzy logic-based hydrometeor identification algorithm has been applied with five variables (Zh, Zdr, ρhv, Kdp, and T) to understand the bulk microphysical properties at different heights within the storm. The presence of bigger graupel particles near the melting layer indicates strong updrafts within the convective core regions. The vertical ice hydrometeor signifies the existence of a strong electric field causing them to align vertically. Numerical simulation with the spectral bin microphysics (SBM) scheme could produce most of the features of the storm reasonably well. In particular, the simulated reflectivity, graupel mixing ratio and rainfall were in good agreement with the observed values. [ABSTRACT FROM AUTHOR]

In tropical countries such as India, increasing the roof albedo helps to reduce the heat ingress through the roof. This further reduces air-conditioning energy consumption in conditioned buildings and increases comfort in unconditioned buildings. In order to help users determine the benefits of high albedo roofs under varying conditions, a simple calculator has been developed. Parameters such as location, building type, roof area, and surface properties of the roof are taken as inputs. Annual EnergyPlus simulations are performed for the given parameters and the results are displayed in both graphical and tabular formats. It also calculates the simple payback by comparing a given base case roof albedo with the proposed roof albedo. The calculator can perform comfort simulations for unconditioned buildings and simulates measures including a radiant barrier system and under deck roof insulation. The calculator also runs a parametric simulation between insulation thickness and roof albedo to find an optimum roof insulation thickness based on incremental internal rate of return. This paper presents the features of the cool roof calculator and the type of analysis that can be performed using the cached results. [ABSTRACT FROM AUTHOR]

Black, K.P.; Reddy, K.S.K.; Kulkarni, K.B.; Naik, G.B.; Shreekantha, P., and Mathew, J., 2020. Salient evolution and coastal protection effectiveness of two large artificial reefs. Journal of Coastal Research, 36(4), 709–719. Coconut Creek (Florida), ISSN 0749-0208. Two offshore reefs constructed at Ullal, Karnataka, on India's west coast, are exhibiting coastal protection benefits. The reefs are large (275 m and 325 m long) and uniquely placed well offshore (600 m and 760 m) in intermediate depths (6 and 7 m below chart datum). Their crests are between low-tide and midtide level. Bathymetric and beach surveys show that sand has accumulated to form two evolving shoreline salients, which are currently 2–3 times the length of the reefs. The salients have grown underwater on the inner shelf to create a large sand-retention zone up to 1 m thick and stretching from the beach to the distant lee of the reefs. The reefs are the first protection structures that have restored the beaches and enhanced sand storage over this broad, severely eroded region, both inshore and on the inner shelf. Prior rubble-mound rock revetments (seawalls) and 50–70-m-long groynes failed to restore the beach in stormy monsoon conditions, while the inner shelf continued to erode. The reefs were designed using a combination of computer simulations, measurements of natural salients in India, and empirical relationships. The methodology that led to the reef shapes/sizes and their position offshore is discussed, along with monitoring results. [ABSTRACT FROM AUTHOR]

Background: Driving simulator (DS) is frequently used in traffic research in order to study various traffic scenarios with related traffic phenomena. This current pilot study assesses off-road driving skills of Indian drivers using driving simulator and perceptual test batteries such as the Test of Visual Perceptual Skills-3 (TVPS-3) and the Rivermead Perceptual Assessment Battery (RPAB). Objectives: The objective of this study is to determine the off-road skills of Indian drivers using DS and comparing their performance on visual perceptual test batteries (TVPS-3 and RPAB). Study Design: An observational cross-sectional study design was chosen for the research. Methods: A sample size of 30 participants, based on convenient sampling method, who met the following inclusion criteria were included: participants with driving experience of ≥1 year, age range: 20--60 years, and no obvious visual and/or physical impairment or other such comorbidities. Participants underwent evaluation in two phases. Phase 1 included screening of participants for inclusion criteria and assessment of screened participants on DS. Driving Simulator: Participants were tested on "city driving test" for 10 min. In Phase 2, after completing assessment on driving simulator, participants were randomly assigned to either of the perceptual tests. By perceptual tests, participants' perceptual abilities were assessed either using RPAB or TVPS-3. Results: The RPAB group had 12 males and 3 females, whereas the TVPS-3 group had 11 males and 4 females. The mean age for the RPAB group was 40.33 ± 11.33 and for the TVPS-3 group was 40 ± 11.06. Pearson's correlation to compare the visual perceptual tests and performance on DS was found to be statistically significant (RPAB group: r = 0.80, P = 0.00, 95% confidence interval [CI]: 0.50--0.92 and TVPS-3 group: r = 0.82, P = 0.00, 95% CI: 0.56--0.93). The performance of Indian drivers on perceptual tests and driving simulator is highly correlated. Conclusion: There is a strong positive correlation between off-road driving skills (DS) with visual perceptual skills (tested on TVPS-3 and RPAB). [ABSTRACT FROM AUTHOR]

Thomas, J.; Velamala, S.N., and Prasad, K.V.S.R., 2019. Numerical simulation of tidal constituents in Thane Creek and the Ulhas estuary, west coast of India. Journal of Coastal Research, 35(2), 376–388. Coconut Creek (Florida), ISSN 0749-0208. Complex tidal progression in creeks and estuaries attract a large number of researchers around the globe. The main motive of the present work is to study the complex tidal variation of Thane Creek and the Ulhas estuary on the west coast of India. A Delft3D model was applied to simulate its depth-averaged hydrodynamics and tidal propagation along the system, and the calibration and validation of this model revealed its accuracy. The system was classified as hyposynchronous; a gradual decrease in the amplitude was noticed from mouth to upstream in all seasons. The interpretation of the major tidal constituents amplitude and phase, shallow water constituents, form number, and tidal asymmetry showed the dynamic nature of the system. The form number results revealed that the tide in Thane Creek and the Ulhas estuary is mixed semidiurnal. The tidal asymmetry parameter indicated a seasonal variation of ebb and flood current in Thane Creek and the Ulhas estuary, which favors sedimentation processes in the system with consequent erosion and deposition. For the future, these results will help in understanding sediment transport and the corresponding shoreline changes and the biogeochemical processes of this dynamic system and help to establish its sustainability.

How open should a developing country's agriculture be to the world economy? What are the medium-term effects for growth and income distribution of 'close' integration with world agricultural markets through trade liberalisation and domestic reform? And what are the implications of the 'strategic' integration of agriculture with world markets? Using a dynamic computable general equilibrium model, these questions are addressed for the Indian economy. The simulation results show that the costs of 'close' integration are large and unevenly distributed, irrespective of whether the agricultural reform is immediate or gradual. One form of 'strategic' integration is operationalised that yields more desirable outcomes in terms of growth and income distribution. The paper also compares the effectiveness of the two policy regimes in coping with an adverse supply shock. [ABSTRACT FROM AUTHOR]

Summer precipitation over the Western Ghats and its adjacent Arabian Sea is an important component of the Indian monsoon. To advance understanding of the physical processes controlling this regional precipitation, a series of high-resolution convection-permitting simulations were conducted using the Weather Research and Forecasting (WRF) Model. Convection simulated in the WRF Model agrees with TRMM and MODIS satellite estimates. Sensitivity simulations are conducted, by altering topography, latent heating, and sea surface temperature (SST), to quantify the effects of different physical forcing factors. It is helpful to put India's west coast rainfall systems into three categories with different causes and characteristics. 1) Offshore rainfall is controlled by incoming convective available potential energy (CAPE), the entrainment of midtropospheric dry layer in the monsoon westerlies, and the latent heat flux and SST of the Arabian Sea. It is not triggered by the Western Ghats. When offshore convection is present, it reduces both CAPE and the downwind coastal rainfall. Strong (weak) offshore rainfall is associated with high (low) SSTs in the Arabian Sea, suggested by both observations and sensitivity simulations. 2) Coastal convective rainfall is forced by the coastline roughness, diurnal heating, and the Western Ghats topography. This localized convective rainfall ends abruptly beyond the Western Ghats, producing a rain shadow to the east of the mountains. This deep convection with mixed phase microphysics is the biggest overall rain producer. 3) Orographic stratiform warm rain and drizzle dominate the local precipitation on the crest of the Western Ghats.

A direct numerical simulation (DNS) with the decaying turbulence setup has been carried out to study cloud-edge mixing and its impact on the droplet size distribution (DSD) applying thermodynamic conditions observed in monsoon convective clouds over Indian subcontinent during the Cloud Aerosol Interaction and Precipitation Enhancement EXperiment (CAIPEEX). Evaporation at the cloud-edges initiates mixing at small scale and gradually introduces larger-scale fluctuations of the temperature, moisture, and vertical velocity due to droplet evaporation. Our focus is on early evolution of simulated fields that show intriguing similarities to the CAIPEEX cloud observations. A strong dilution at the cloud edge, accompanied by significant spatial variations of the droplet concentration, mean radius, and spectral width, are found in both the DNS and in observations. In DNS, fluctuations of the mean radius and spectral width come from the impact of small-scale turbulence on the motion and evaporation of inertial droplets. These fluctuations decrease with the increase of the volume over which DNS data are averaged, as one might expect. In cloud observations, these fluctuations also come from other processes, such as entrainment/mixing below the observation level, secondary CCN activation, or variations of CCN activation at the cloud base. Despite large differences in the spatial and temporal scales, the mixing diagram often used in entrainment/mixing studies with aircraft data is remarkably similar for both DNS and cloud observations. We argue that the similarity questions applicability of heuristic ideas based on mixing between two air parcels (that the mixing diagram is designed to properly represent) to the evolution of microphysical properties during turbulent mixing between a cloud and its environment.

Background: Demographic and socioeconomic changes such as increasing urbanization, migration, and female education shape population health in many low- and middle-income countries. These changes are rarely reflected in computational epidemiological models, which are commonly used to understand population health trends and evaluate policy interventions. Our goal was to create a "backbone" simulation modeling approach to allow computational epidemiologists to explicitly reflect changing demographic and socioeconomic conditions in population health models. Methods: We developed, evaluated, and "open-sourced" a generalized approach to incorporate longitudinal, commonly available demographic and socioeconomic data into epidemiological simulations, illustrating the feasibility and utility of our approach with data from India. We constructed a series of nested microsimulations of increasing complexity, calibrating each model to longitudinal sociodemographic and vital registration data. We then selected the model that was most consistent with the data (i.e., greater accuracy) while containing the fewest parameters (i.e., greater parsimony). We validated the selected model against additional data sources not used for calibration. Results: We found that standard computational epidemiology models that do not incorporate demographic and socioeconomic trends quickly diverged from past mortality and population size estimates, while our approach remained consistent with observed data over decadal time courses. Our approach additionally enabled the examination of complex relations between demographic, socioeconomic and health parameters, such as the relationship between changes in educational attainment or urbanization and changes in fertility, mortality, and migration rates. Conclusions: Incorporating demographic and socioeconomic trends in computational epidemiology is feasible through the "open source" approach, and could critically alter population health projections and model-based evaluations of health policy interventions in unintuitive ways.

Southern peninsular India experiences widespread thunderstorm activities during the pre-monsoon season due to the presence of a north-south trough, an easterly trough, and low pressure areas over the surrounding Indian Seas. In March 2008, southern peninsular India received unusual heavy rains because of the interaction between a large amplitude easterly trough and a mid-latitude westerly trough during 12 to 14 March, and because of the formation of a low pressure system over the Arabian Sea during 21 to 24 March. Simulation of these two heavy rainfall events is attempted using the Weather Research and Forecasting ( WRF) model. The model's performance is studied in terms of the wind, pressure, movement of these synoptic scale systems, moisture and rainfall fields. Results indicate that this model has the capability to predict the movement of both easterly and westerly troughs and to simulate low pressure very well. The model is able to capture the areas of precipitation maxima in both the cases. The bias score is found to be more than 1 in precipitation thresholds up to 35 mm and less than 1 in precipitation thresholds above 35 mm. The maximum values of critical success index ( CSI) and equitable threat score ( ETS) are 0.49, 0.32 and 0.42, 0.13 in 24 and 48 h forecasts, respectively, in Case 1 and 0.69, 0.23 and 0.71, 0.19 in Case 2. The values of CSI and ETS drop considerably above the 30 mm rainfall threshold in both 24 and 48 h forecasts showing that the model performs better in lower rainfall thresholds.

I examine the potential impact of the anticipated future marriage squeeze on nuptiality patterns in China and India during the twenty-first century. I use population projections from 2005 to 2100 based on three different scenarios for the sex ratio at birth (SRB). To counteract the limitations of cross-sectional methods commonly used to assess the severity of marriage squeezes, I use a two-sex cohort-based procedure to simulate marriage patterns over the twenty-first century based on the female dominance model. I also examine two more-flexible marriage functions to illustrate the potential impact of changes in marriage schedules as a response to the marriage squeeze. Longitudinal indicators of marriage squeeze indicate that the number of prospective grooms in both countries will exceed that of prospective brides by more 50% for three decades in the most favorable scenario. Rates of male bachelorhood will not peak before 2050, and the squeeze conditions will be felt several decades thereafter, even among cohorts unaffected by adverse SRB. If the SRB is allowed to return to normalcy by 2020, the proportion of men unmarried at age 50 is expected to rise to 15% in China by 2055 and to 10% in India by 2065. India suffers from the additional impact of a delayed fertility transition on its age structures. [ABSTRACT FROM AUTHOR]
