Investigation into some of the engineering properties of soil in Damot Gale district
Investigation of the sub-surface condition is used for the effective design of the structural elements. It is also very crucial to obtain information on the type, characteristics, and distributions of soil and rock underlying a site for proposed structures. I investigate some of the engineering properties of soils collecting 20 disturbed and 10 undisturbed soil samples from 10 different test pits at the average depth of 1.5m to 3m and laboratory tests conducted. The natural moisture content of soil ranges from 24% - 44.47% and bulk unit weight range from 16.4 to 19.7 kN/m3. The specific gravity of soil varies from 2.57 to 2.84 and the particle size analysis showed that the dominant proportions of soils in the study area are the clay. Consistency limit test results in the research area showed the liquid limit ranges from 46 to 73%, plastic limit ranging from 13 to 38%, and plasticity index ranging from 13 to 38 %. The unconfined compressive strength of the soils in the study area ranges from 80 -215kN/m2 and undrained shear strength range from 40 – 107.5 kN/m2. Finally, a one-dimensional consolidation test was done.

Impact assessment of land use land cover change on sediment yield using SWAT Model
Quantifying the impacts of land use change and land cover practices on the hydrological response of a watershed has been an area of interest for the hydrologists in recent years as this information could serve as a basis for developing sound watershed management interventions. This thesis aims at evaluating the effects of land use land cover change on sediment yield using SWAT model simulation in Gadarwara watershed located in Narmada Basin. The degree and type of land cover influences the rate of infiltration, runoff and total sediment loads transported from a watershed. It often results in significant degradation of land resources such as loss of soil by erosion, nutrient leaching and organic matter depletion. However very few studies in India, have used the physically based hydrological models along with the land use land cover change conditions. Hence in this current work SWAT model has been used to assess the impact of land use land cover changes on monthly sediment of Narmada River Basin. The SWAT model has been calibrated and validated against the monthly streamflow for the gauging station of Gadarwara, situated along the Shakkar River. The results depict that SWAT model usually performs well in simulating runoff according to Nash-Sutcliffe efficiency (NSE), Coefficient of determination (R2) and Percentage bias (PBIAS) values. For stream flow the NSE, R2 and PBIAS values were 0.86, 0.89, 12.2 during calibration period and 0.83, 0.87 and 14.5 during validation period respectively. For sediment the efficiency decreased due to less availability of data and the NSE, R2 and PBIAS values were 0.66, 0.68 and -10.9 during calibration period and 0.65, 0.67 and -5 during validation period respectively. The results of the study indicated that increase in forested areas result in decreasing sediment yield Agriculture land contributes mainly in sediment yield hence reduction in agriculture land leads in reduction of sediment yield and increase in agriculture land results in increase of sediment yield.

Wireless power transmission system using microwaves
It has become an important undeniable fact that power transmission is optimum and losses are decreased, and thus it is necessary to search out new ways in which for power transmission which may be helpful to the industry, hence the need to use wireless systems is vital The transfer of power from the source to the receiver is a technology that has existed for over a century. Wireless power transfer (WPT) has been created possible in recent years thanks to advances in technology and higher implementations of transfer techniques, like Microwave Power Transfer (MPT). The MPT system works by converting power to microwaves through a microwave generator and then transmitted that power through free space wherever it is received and born-again back to power at a special device referred to as rectenna. The applications of MPT are numerous, not solely to alter the approach existing technologies work, however additionally as historical constructs for future constructs. Whereas the advantages are nice, there squared several measured limitations and drawn sides of MPT, necessitating the discussion of attainable strategies WPT. The transfer of power wirelessly has the potential to fully disrupt and revolutionize existing and future technologies.

Face Recognition Attendance System
The Real-time Attendance Maintaining System is difficult process if it is done manually. It is an important requirement in the modern era to improve the working efficiency of the entire private and public sector. There are many smart and automated forms of biometrics to monitor the movement of students or employees such as fingerprint, palm scanning, iris,voice recognition etc. Face Recognition is one of them. By using this system, the issue of fake attendance and proxies can be solved. This paper suggests a robust procedure for monitoring attendees using facial recognition. The method proposed here for real-time character identification involves a facial recognition technique using Haar-like features with a Cascade classifier. For the purpose of face recognition histogram of local binary patterns (LBPH) are used. The major steps in the proposed system are capturing the images of the students, storing the captured images in the database, detecting the faces and recognizing them. The comparison is done by crosschecking the detected face with the database of student’s faces. This smart system will be effective way to maintain the attendance and records of students.

E-assessment using image processing in infinity exam
This paper features a software system called ∞Exam (Infinity Exam) which supports (primarily in higher education) paper-based examination and makes it easier, more comfortable, and speed up the whole process while making keeping every single positive attribute of it but also reducing the number of negative aspects. The approach significantly differs from the ones used in the previous 10+ years which were implemented in such a way that they could not reproduce and replace the traditional based paper examination model. The heart of the article relies on the most important element of the software which is the image processing flow. The way of conducting testing the knowledge of a person using Multiple Choice Questions (MCQ) has been increased gradually. In education industries (like schools and colleges) it is more common now days having tests using multiple-choice questions. Even in conducting interviews, it is used. The current day scenario is either using OMR technology to correct the test or manually. In real-time, it is quite difficult to have OMR at all the time and manually it is highly taking the time to correct and it may give you the error. We address this issue, in our proposed system we using digital image processing technique to correct the answer using multiple choice questions in python. We are here using the Open Source Computer Vision Library (Open CV) to process and correct the answer. Python is the best language to implement this concept with the available Open CV library. In this system, we also implement it in the Django environment.

Peer to peer learning- An effective tool in students learning
Innovative teaching methods have to be adopted in today’s mindset of youngsters. Outcome-based education have to a giant leap forward to improve technical education in India and ensure learning registers in their young minds and make them compete with their competitors around the world globally. This can be achieved only if the knowledge posed by them is deep routed and are strong with their concepts. Innovative teaching methods which are the most subsets of Outcome-based education is a strong encouraging platform for students to encourage learning the concepts from their peers by which they encompassed with easy way learning. They seem to have more focused and fun during their learning process. Finally, the outcome is measured through knowledge of Via their internal assessment. As all the engineering colleges follow NBA accreditation in deciding the quality of the students, they have also streamed and asked to adopt modern ways of teaching such as ICT, Model Demonstration, flip class, poster presentation, etc. In such an attempt an effort has been taken to show how effective will be peer to peer learning in the form of flip class. In this present paper, a case study is developed through CO-PO mapping and attainment for Mechanical Engineering Students of Tier-II.[2] for the VII semester Mechanical Engineering Students for the subject “Operations Research
