User centric economic demand response management in a secondary distribution system in India

This study presents a demand response (DR) model to curtail the load during peak hours in a secondary (230/440 V) distribution system of Tamil Nadu Generation and Distribution Corporation (TANGEDCO), a state-owned enterprise, India. TANGEDCO penalises utilities if they violate their permitted contractual limit of demand. Conventional demand control usually curtails a specific region of the secondary distribution network. The limitation of the complete blackout of the particular region in the distribution network increases the loss of load probability. Hence, this project implements an economic DR model in real time using demand side forecasting and by scheduling air-conditioning loads based on their priority. The pilot project is executed and is monitored at the National Institute of Technology, Tiruchirappalli, India campus. A standard back propagation neural network is used for forecasting a 15 min interval ahead maximum demand in kVA. This economic model comprises of a communication network that uses ON/OFF switching wirelessly controlled relay modules. Finally, the benefits and the strategy involved in the project are presented. It is found that the proposed scheme prevents the electrical demand from exceeding the contractual limit, whereby the penalty due to the violation is zeroed when compared to the previous year.

Development of Physics Teaching Materials Using a Simple Superconducting Coaster

Superconductivity is a renowned phenomenon, wherein a small neodymium magnet hovers on a superconductor. However, a desk-size superconducting coaster, which floats and runs on a magnet, is rarely used in classroom exhibitions. Moreover, students’ production and demonstration of this phenomenon has been relatively difficult. Consequently, a simple interactive experimental system and teaching materials associated with methods of controlling the coaster’s speed using a multiple-coil configuration were proposed by the National Institute of Technology, Ariake College. This experiment makes it possible to deepen students’ understanding of electromagnetism and superconductivity through direct experience while also exposing them to programming methods using “Arduino.” This paper describes the construction method of the desk-sized superconducting coaster and the analytical methods used to evaluate it.

Monitoreo de los niveles de benceno, hidrocarburos aromáticos y compuestos oxigenados en combustibles fósiles importados en Paraguay

El trabajo fue realizado en el Laboratorio de Combustibles y Lubricantes del Instituto Nacional de Tecnología, Normalización y Metrología – INTN, en el marco del proyecto 14-INV-193, financiado por el CONACYT y el INTN.

El periodo de estudio abarca desde febrero de 2016 a julio de 2017. Los resultados obtenidos en promedio, se encontraron dentro de los límites establecidos en la legislación vigente, aunque se observaron casos puntuales donde excedieron los límites permitidos. Estos datos son importantes para tener un diagnóstico de la situación en cuanto a niveles de compuestos nocivos para el medioambiente y la salud humana, así como para la toma de decisiones de entes reguladores

Integrating employability skills in engineering education

Aim: This paper examines the curricula and pedagogical practices of Gujarat colleges associated with the Gujarat Technical University and the National Institute of Technology, Surat, concerning the instruction of communication skills. This encompasses the vast majority of Gujarat’s engineering schools.Method: To better understand the challenges of instructing engineering students, a qualitative study was conducted in which eight English teachers from different engineering colleges in and around Surat were interviewed. To complete the research, eight English professors at different engineering schools in and around Surat, Gujarat, were contacted. These educators were chosen to represent a range of ages, levels of experience and education, and specialisations.Findings: This paper uses the study’s findings to argue that engineering curricula should incorporate several activities aimed at improving engineers’ employability. From this, we can infer that the chalk-and-talk approach to teaching engineers communication skills is ineffective. Furthermore, industry standards have increased rapidly.Implications/Novel Contribution: This research contributes to the body of literature by providing empirical evidence for the importance of fostering employability skills in one’s communication repertoire. While generalisations from this study are obviously not possible, it is safe to assume that English instructors in India’s engineering colleges face similar difficulties to those identified in this study’s sample. Second, despite efforts to improve the situation, recent engineering graduates’ lack of employability skills continues to trouble both Indian employers and graduates alike.

Source apportionment studies for particulates (PM10) in Kozhikode, South Western India using a combined receptor model

ABSTRACTIn the present work, source apportionment studies were carried out for particulate matter – one among the significant pollutants as addressed by The National Ambient Air Quality Standards. Advantages and disadvantages of each receptor model were addressed using a combined receptor model which integrates Factor Analysis (FA), Positive Matrix Factorisation (PMF) and Chemical Mass Balance (CMB). Verification of the approach was done using sets of synthetic data as well as field data from Kozhikode. Sampling was carried out in National Institute of Technology, Calicut for a period of over 26 days with 24-hour sampling. The sampling gave an average PM concentration value in the range of 29.174–129.176 µg m−3. Studies using field data revealed five dominant sources and their contributions obtained from CMB and PMF were compared. Soil dust (contribution from CMB: 18%; contribution from PMF: 16%), marine aerosol (17%; 25%), construction and aggregate processing (46%; 11%), garden waste combustion (18%; 45%), and vehicular exhaust (1%; 3%) were major contributors in the site under study. The outcomes of the study integrated with the support of local authorities and by the acceptance of residents can definitely curb the pollution levels in the site under the study.

Experimental study of embankment breach based on its soil properties

ABSTRACT Understanding of the phenomenon of embankment breach via overtopping is complex but essential for forecasting the flood inundation map and developing an emergency action plan. Case studies of embankment failures caused by overtopping indicate that apart from hydraulic forces, the influence of the soil properties also plays a crucial role in the formation of the breach. The influence of the soil properties on the breaching process was investigated by performing 13 experiments in the hydraulic engineering laboratory of National Institute of Technology, Rourkela, India. The data obtained from the overtopping failure of these embankments are analyzed and presented in this article. Further, a multivariable regression was performed using the test data of 25 embankments to obtain the relationship between the breach parameters and the soil properties (control variables). New nondimensional control variables, such as embankment soil factors, relative compaction effort, relative particle size, and erodibility, were proposed for developing the relationships. An attempt is made here to understand the influence of these control variables on the dam breach that is not reported so far.

Divergence analysis of black gram (Vigna mungo L.) for grain yield and yield components

Thirty-two black gram genotypes were evaluated using twelve quantitative and fifteen qualitative traits at Motilal Nehru National Institute of Technology (MNNIT), Allahabad, India to determine genetic divergence using important yield and yield contributing traits. The number of pods plant-1, peduncle length, harvest index and biomass yield plant-1 are important traits affecting grain yield response in black gram. The quantitative traits like; pod length, number of pods plant-1, 100-grain weight as well as qualitative traits like; stem pubescence, leaf pubescence, pod pubescence, pre mature pod colour and plant growth habit which have major contribution in the genetic divergence of black gram. The number of pods plant-1 is most important grain yield contributing and genetic divergence developing traits. The genotypes were classified into six clusters based on Euclidean distance. The genotypes belonging to cluster I, II and III were highly diverse than genotypes lies in cluster IV, V and VI. The genotypes IPU 99-176, UH 82-51, GE 154, IPU 99-3 and NG 2119 had good potential to develop high yielding transgressive segregants. The wide genetic diversity is present in black gram. The present study will be much helpful for selection of the parental lines to develop good grain yield producing black gram cultivar in accordance with changing climate.

Metodologia de projeto ergonômico aplicada ao desenvolvimento de bancos de arremesso de atletas paralímpicos brasileiros

The objective of this article was to present and describe the project methodology implemented in the development of five throwing frames for paralympic athletes. The process was divided into project different phases / stages, which, although following a logical sequence of development, include activities performed simultaneously. The athletes and technicians were invited to participate in technical meetings with the research group at INT. These technical meetings were held throughout the project, so that athletes and their technicians could interact with the project team of the Three-Dimensional Models Laboratories (LAMOT) and Ergonomics Laboratory (LABER) athe Industrial Design Division at the National Institute of Technology. 3D motion captured and laser scanning captured with 1D anthropometric measurements were collected in order to provide information to the bank usability designer and anthropometric dimensions of the athletes. With this information, the LAMOT / DVDI project team developed project alternatives that were presented to the athletes and technicians. The chosen project frame alternative allowed greater rigidity to the seat. Athletes participated in all subsequent stages of prototype development and final testing in use. The conclusion was that the methodology provided a logical and comprehensible structuring of the product development process for all the actors involved in the project, even from different areas of activity, and thus, could contribute in a harmonic and productive way to the final result.

Active Learning Strategy at a Collegewide Level in NIT, Gifu College

For more than fifteen years, National Institute of Technology (NIT), Gifu College has promoted the practice of education aimed at improving students’ activeness through student-centered approaches such as ICT education and e-Learning. The past educational practices led to the acquisition of the “Support Program for Contemporary Educational Needs (GP)” (2004) and the “Acceleration Program for Rebuilding of University Education (AP)” (2014) by the Ministry of Education, Culture, Sports, Science and Technology (MEXT). It is effective to use digital educational materials in the practice of AL. As educational materials used in AL class, we are preparing them based on the viewpoints of our college senior graduates who have worked long and/or are currently working in Japanese high-tech industries as leading engineers. Also, our college has established a rule, a system for student guidance and a server system where students who have learned the educational materials can gain practical engineering credit points through extra curriculum activities. In our college, AL, which is practiced by all teachers, is categorized into three levels. Respective teachers are required to describe the type of AL in their syllabus. Moreover, our college is aiming for students to acquire the ability to describe matters related to engineering in English, while promoting the interactions between the teaching of technical English and that of the specialized subjects through active education as shown in subjects highly recommended by corporate engineers.

Comparison of Artificial Neural Network and Regression Approaches for Evaluation of Hydrodynamic Performance of Quarter Circular Break Water

Quarter-circle Break Water (QBW) is a modified semi-circular breakwater, which are similar to caisson consists of a quarter circular surface facing incident waves, with horizontal bottom and a rear vertical wall and are generally placed on a rubble mound foundation. QBW may be constructed as emerged with and without perforations that may be one side or on either sides. By these perforations, the energy is dissipated owing to the formation of eddies and turbulence is created inside the hollow chamber. In this paper, the data collected from the experimental work carried out at National Institute of Technology, Surathkal is analysed by plotting the non-dimensional graphs of reflection coefficient, reflected wave height and incident wave height for various values of wave steepness. These values are used for prediction of QBW adopting Artificial Neural Network (ANN) and Regression (REG) approaches. In ANN, Multi-Layer Perceptron (MLP) and Radial Basis Function networks are considered for training the network data. Goodness-of-Fit (GoF) test viz., Kolmogorov-Smirnov test statistic and Model Performance Analysis (MPA) viz., correlation coefficient, mean absolute error and model efficiency are applied for checking the adequacy of ANN and REG approaches to the observed data. The results of GoF test and MPA indicates the MLP is better suited for evaluation of hydrodynamic performance of QBW.
