Countries pursuing economic progress are required to resort to increasing degrees of energy usage. Achieving these levels of energy output and utilisation through present technologies is not only difficult and expensive, but also environmentally unsustainable. Energy efficiency generates substantial financial savings while simultaneously improving environmental quality. Despite these benefits, developing countries like India are missing out energy efficiency opportunity and instead concentrating on increased energy production. This report deals with the identification of barriers which prevent implementation of energy efficiency standards, aside from studying drivers which promotes its adoption. The various barriers and drivers are discussed and identified for both residential and commercial sectors in Davangere City, Karnataka State, India. The factor analysis is carried out by principal component analysis (PCA) method to find the barriers which prevent from achieving energy efficiency.

Cleaner production enabled organizations to picture the idea of ecological manageability practically speaking and to put stock in the likelihood of creating more with less, other than diminishing natural expenses. Be that as it may, in spite of the fact that cleaner generation has just been acknowledged and is progressively connected, it isn't a standard technique for overseeing ecological perspectives. In this article, a brief review about a cleaner production is presented. As well, the various methodologies adopted for CP and quality tools which are used to reduce the resources have been discussed. The barriers encountered by the CP and strategies to overcome these barriers is also discussed.

In this study, a forced convection solar crop dryer is designed and constructed to dry different crops. This paper explains the design calculations for the collector, different alternatives for the collector fins and Computational Fluid Dynamics (CFD) analysis of the collector fins for the performance of the different alternatives. From the study, the area required to dry 100kg of crop is 10m 2 ; however, it also depends upon the drying time and the moisture content in the crop. Based on the CFD results among all alternatives, chamfered rib fin was selected as the best alternative. By using the calculation and the simulation results the collector is constructed and tested with different conditions. The closed drying is faster compared to the open sun drying. Around 50% of the drying time can be reduced by using the crop dryer. Because of the closed and the controlled rate of drying the quality of the crops remains same in terms of colour, texture and taste.

Making labs open-ended pushes students to think for themselves and think harder. Outcome-based education is an educational theory that bases each part of an educational system around goals (outcomes). Outcome-based methods have been adopted in education systems around the world, at multiple levels. Measuring program-specific outcomes in engineering education is a challenge for teaching faculty in general and doing so for a laboratory program and through an open-ended experiment is even more challenging. This paper explains the planning and execution of open-ended experiment in Industrial Engineering and Simulation Laboratory and also it focuses on the evaluation process, rubrics developed, and attainment of program-specific outcome in Industrial and Production Engineering Program.

The commercial buildings are typically all buildings, which are not residential, industrial, or agricultural. The sector includes service businesses, such as shops and stores, hotel, restaurants, as well as a wide range of facilities. The commercial sector alone consumes around 20% of the total energy. The main reason is that, there is a lot of energy wastage in the commercial sector. For a developing country like India, characterized by severe energy shortages, the need for energy conservation is of most priority. The energy efficiency improvements in such sector go a long way in their substantial development. In this backdrop, the paper analyzes the energy consumption and environmental impact in commercial sector of Davangere, Karnataka state, India. The energy consumption pattern is studied and energy efficiency is estimated in terms of Specific Energy Consumption (SEC). Further, energy consumption potential is estimated. The environmental impact in terms of Carbon dioxide (CO 2) emission is estimated and also wide ranges of energy saving options are identified. The factors influencing the energy efficiency and energy consumption in these sectors is also studied. The factors are analyzed using multiple regression models.

The process is highly iterative process involving a cyclical process of idea generation, evaluation, and design improvement until the design requirement is met. It is a widely used design strategy due to its intuitive nature and effectiveness in facilitating design improvement, hence calls for the need of the hour to enhance students' cognitive levels. Engineering design courses can be best learnt through practical learning (often termed as Project Based Learning) by course projects, thus delivering this course in the early stages of mechanical science engineering students by offering projects as pedagogy is often a challenge on the part of the tutor. This paper collectively presents simple techniques adapted in conducting the projects for third semester undergraduate Industrial Production engineering students. A systematic approach was followed in the formation of the student teams, proposing the problem statements, students preparing for the reviews according to scheduled timelines, modeling the prototypes, conducting the reviews and preparing the PowerPoint presentations and project reports. By following this pedagogical method Program Outcome (c: Ability to design systems, components, or processes to meet customer needs) and (g: Ability to communicate effectively in both oral and written forms and to become proficient in working with diverse teams) were mapped for the assessment. It was also observed that there was an improvement in the PO attainment, a better team dynamics were observed, the quality of the projects was enhanced in terms of better idea generation, report writing and power point presentation also proved a better quality.

Programs have integrated classroom instruction with laboratory experiences to provide students a significant opportunity to learn. A fundamental component in professional education is the link between theory and practice. However, many students in professional education programs experience a lack of coherence between theory and practice, which is often described as the theory practice gap. This work is a part of "Bridging the Gap" in metrology and quality engineering course, designed for the undergraduate students of VI Semester Industrial and Production Engineering of BVBCET, Hubli, an autonomous institute. Two problem statements were given to the students; one was on the process capability analysis of machines and another on the construction of control chart for variables, which they have to solve after conducting the experiments in machine shop in batches. The students had to chalk out the necessary information to conduct the experiment like profile, sample size, N.Vijayakumar Department of Industrial& Production Engineering B.V.B.

But do we all know, how laborious it is to shell the maize? Dehusking and shelling are important post-harvest activities in maize crop, predominantly done by women. These activities involve a lot of drudgery as these are done manually. The maize shelling with the tool makes women's lives difficult and yields very low level of output. Moreover, dehusking as a separate activity precedes shelling that brings additional burden on farmers. They may employ labourers or use machines. But in villages, there is a shortage of labourers, and their wages are also pretty high. The farmers or field owners find it difficult to afford the machines. In order to make it affordable and more convenient to shell the maize, and as a part of our academic project, we have developed a “Crank Operated Maize Sheller” using ergonomic and mechanical considerations for dehusking and shelling. It consists of feeder from where the maize is inserted. The crank is connected to the blade. When the crank is turned, the blade rotates and shells the maize. The machine is operated by 1 person and requires feeding of cobs one by one.

The existing type of seed measuring system involves the weighing the seeds approximately and packing them or processing them. So the focus of the project is on building a system which could tackle the problem of inaccurate seed measurement and counter the accurate number of seeds. For this purpose IR sensor based counting system which would operate the belt conveyor after certain number of grains/seeds falls in the box and the next box comes into the cycle. This circuit is configured using a microcontroller and a counter display LED for displaying the counts.

Energy input is vital in every sector of an economy for survival and growth. The consumption in residential and commercial sector is going to rise further in the near future, as we see increase in population. Homes and business represent a significant portion of global energy demand, especially when electricity usage is considered. Globally this demand will grow substantially in the residential and commercial sector. The energy use in residential and commercial sector is an important area for campaigns to conserve energy. For a developing country like India, characterized by severe energy shortages, the need for energy conservation is of top most priority. The energy efficiency improvements in these sectors go a long way in their sustainable development. The share of different energy carriers used in both the sectors such as electricity, diesel and LPG is studied. The energy efficiency level is computed in both the sector in terms of Specific Energy Consumption (SEC). The factors influencing the energy efficiency and energy consumption in these sectors is studied. The factors are analyzed using multiple regression models. The regression analysis is carried out using SPSS (Statistical Package for Social Science software version 20). Barriers and drivers for the efficient use of energy in both the sectors are also identified and ranked using their average scores.

Some of the popular names in the past have been sustainable engineering and concurrent engineering. While each of these names has a different flavor to it, the underlying principle of effective engineering education has been its ability to provide practical and functional learning opportunities to students. Experiential learning, which encompasses all types of practice-based learning opportunities, is the founding principle of a successful engineering education model. This paper presents an approach to enhance active and collaborative learning in ‘Metal Cutting’ laboratory by the undergraduate students of V Semester Industrial & Production Engineering using the concept of “Design of Experiments”, to study the effects of various parameters on machining performance. The paper also describes the assessment of program outcome ‘3b’ of ABET criteria through laboratory experiment.

to develop their own experiments, instead of merely following the already set guidelines from a lab manual or elsewhere. Making labs open-ended pushes students to think for themselves and think harder. Outcome-based education is an educational theory that bases each part of an educational system around goals (outcomes). Outcome-based methods have been adopted in education systems around the world, at multiple levels. Measuring program-specific outcomes in engineering education is a challenge for teaching faculty in general and doing so for a laboratory program and through an open-ended experiment is even more challenging. This paper explains the planning and execution of open-ended experiment in Industrial Engineering and Simulation Laboratory and also it focuses on the evaluation process, rubrics developed, and attainment of program-specific outcome in Industrial and Production Engineering Program.
pursuing economic progress are required to resort to increasing degrees of energy usage. Achieving these levels of energy output and utilisation through present technologies is not only difficult and expensive, but also
environmentally unsustainable. Energy efficiency generates substantial
financial savings while simultaneously improving environmental quality.
Despite these benefits, developing countries like India are missing out energy efficiency opportunity and instead concentrating on increased energy production. This report deals with the identification of barriers which prevent implementation of energy efficiency standards, aside from studying drivers which promotes its adoption. The various barriers and drivers are discussed and identified for both residential and commercial sectors in Davangere City, Karnataka State, India. The factor analysis is carried out by principal component analysis (PCA) method to find the barriers which prevent from achieving energy efficiency.
embraced experiential learning as a true learning
methodology for students to obtain occupational skills
valued by employers. Programs have integrated
classroom instruction with laboratory experiences to
provide students a significant opportunity to learn. A
fundamental component in professional education is
the link between theory and practice. However, many
students in professional education programs
experience a lack of coherence between theory and
practice, which is often described as the theory
practice gap. This work is a part of "Bridging the Gap"
in metrology and quality engineering course,
designed for the undergraduate students of VI
Semester Industrial and Production Engineering of
BVBCET, Hubli, an autonomous institute. Two
problem statements were given to the students; one
was on the process capability analysis of machines
and another on the construction of control chart for
variables, which they have to solve after conducting
the experiments in machine shop in batches. The
students had to chalk out the necessary information to
conduct the experiment like profile, sample size,

subgroup size and finally analyze the experimental
data to decide whether machine is capable to meet the
specifications of part and detect the presence of
assignable or un assignable causes of variation using
process capability analysis and control chart
respectively. After the completion of this exercise, the
students could realize the importance of process
capability analysis and control charts in the
manufacturing industries. This activity was step
forward in bridging the gap between theory and lab
through experiential learning. The performance
indicators (PIs) of the ABET program outcome '3b'
were underlying the motivators while designing the
present experiential learning activity.
important constituents of our food. But do we all know, how
laborious it is to shell the maize? Dehusking and shelling are
important post-harvest activities in maize crop,
predominantly done by women. These activities involve a
lot of drudgery as these are done manually. The maize
shelling with the tool makes women's lives difficult and
yields very low level of output. Moreover, dehusking as a
separate activity precedes shelling that brings additional
burden on farmers. They may employ labourers or use
machines. But in villages, there is a shortage of labourers,
and their wages are also pretty high. The farmers or field
owners find it difficult to afford the machines. In order to
make it affordable and more convenient to shell the maize,
and as a part of our academic project, we have developed a
“Crank Operated Maize Sheller” using ergonomic and
mechanical considerations for dehusking and shelling. It
consists of feeder from where the maize is inserted. The
crank is connected to the blade. When the crank is turned,
the blade rotates and shells the maize. The machine is
operated by 1 person and requires feeding of cobs one by
one.
farmers being the backbone of India are constantly in need of
seeds for harvesting and cultivating. The existing type of seed
measuring system involves the weighing the seeds approximately
and packing them or processing them. So the focus of the project
is on building a system which could tackle the problem of
inaccurate seed measurement and counter the accurate number
of seeds. For this purpose IR sensor based counting system which
would operate the belt conveyor after certain number of
grains/seeds falls in the box and the next box comes into the
cycle. This circuit is configured using a microcontroller and a
counter display LED for displaying the counts.
