Interference with other components of the system can create a change in input voltage, which can harm sensitive equipment. Harmonics, voltage sag, & swell themselves can harm the sensitive machinery. A Dynamic Voltage Restorer (DVR) is an equipment that is extensively used in distribution grids to address sag, swell and harmonic issues. Simultaneous simulations of the recommended DVR-based approach in MATLAB/Simulink were carried out to show its efficacy in normalizing voltage profile and harmonics.

Most of the accidents are due to negligence of rules. We are here describing a way to tackle this problem with LASER and PHOTO-SENSOR to make a signalling system which indicates an approaching train. This will reduce the loss of precious life and costs very low to be installed in any un-manned crossing.

Artocarpus heterophyllus is an important source of chemicals of morin, dihydromorin, cyno-macurin, artocarpin, isoartocaepin, cyloartocarpin, arto-carpesin, oxydihydroartocarpesin, artocarpetin, norarto-carpetin, cycloartinone, betulinic acid, artocarpanone and heterophylol which are useful in fever, boils, wounds, skin diseases, convulsions, diuretic, constipation, oph-thalmic disorder and snake bite.

We present our approach in solving task 2 of the AffectMove challenge, which is Reflective Thinking Detection (RTD) while solving a mathematical activity. We utilize temporal data consisting of 3D joint positions, to construct a series of classifiers that can predict whether the subject appeared to possess reflective thinking ability during the given instance. We tackle the challenge of highly imbalanced data by incorporating and analyzing several meaningful data augmentation techniques and handcrafted features. We then feed different features through a number of machine learning classifiers and select the best performing model. We evaluate our predictions on multiple metrics including accuracy, F1 score, and MCC to work towards a generalized solution for the real-world dataset.

In the approach, voltage and current waveform are analysed using wavelet transform. The characteristics of the voltage and current waveform under continuous conduction mode (CCM) and discontinuous conduction mode (DCM) are modelled using multiresolution analysis by wavelet transform. A relation is developed between wavelet coefficients of voltage and current waveforms for estimating the equivalent series resistance (ESR) of a capacitor. The simulation results show small error in estimation of the capacitor ESR. Further, the approach uses waveform analysis in estimating capacitor health; hence, the method is simple over the current injection method for estimation ESR.

A lot of research has been carried out to make it more efficient. With the development of Computational Fluid Dynamics (CFD), the parametric study of a centrifugal pump has become much easier and the complex internal flow can be well predicted to expedite the pump design procedure. The primary objective of this work is to analyse the effect of trailing edge angle of three twisted blades of a radial flow impeller on the hydraulic performance of an impeller using three-dimensional steadystate analysis with the help of commercial CFD software Ansys- 14.0. In this analysis, three impellers are modelled using Ansys BladeGen tool with different trailing edge angles 16, to 27degrees keeping the blade wrap angle constant. The calculations are performed only on the impeller. Three dimensional Navier-Stokes equations are numerically solved by adopting k turbulence model, using finite vol...

The powertrain circuit of solar hybrid bus has been designed and analysed comprehending the addition of solar panels in the powertrain and the increased weight due to the same. Use of hybrid technology reduces the emissions up to 30-35% but with solar energy, emissions can be reduced up to 55%. Comparison between petrol, diesel and CNG is done to justify the use of CNG as the engine fuel. Comparisons are also carried out between Monocrystalline and Polycrystalline solar panels and the one with the more efficiency and power to weight ratio is selected i.e. Monocrystalline solar panels. Monocrystalline panels produce 120180 Watt per meter square against 50-80 Watt per meter square of power produced in case of Polycrystalline panels. Ambiguity in the use of either Ni-MH or Li-ion battery in hybrid buses is r...

The Damper Division of ZF Friedrichshafen AG (case company), Schweinfurt (SCW) has recently decided to move the production of its high running parts to its facility in Pune, India. The project is facing typical Supply Chain Management challenges like delay in serial production and delivery schedules, lack of information exchange, ambiguity over roles and responsibilities, and redundant communication between the two facilities SCW and Pune, thus incurring a high transaction cost and low coordination. The literature review about information flows, business processes and process integration provided four principles that help to integrate the information flow between processes. These principles are – accessibili...

Green management practices is widely discussed topic in today scenario, where global warming and alarming level of population has posed a warning to humans. Various industries, government institutions and social groups are taking steps/initiatives to protect the natural environment. The objective of this study is to propose and validate an instrument to measure green management practice benefits with respect to organizational performance. Exploratory Factor Analysis (EFA) have been used to build constructs which will serve the purpose to measure green management practice adoption and Confirmatory Factor Analysis (CFA) was used to validate the factor structure for observed variables.

Most recent approaches focus on classification, regression or forecasting tasks on such data. In forecasting, it is necessary to not only forecast the right value but also to forecast when that value will occur in the irregular time series. In this work, we present an approach to forecast not only the values but also the time at which they are expected to occur.
