Bharathiar University

Bharathiar University (BU) was established in February 1982 under the provisions of the Bharathiar University Act 1981. In May, 1985 the University received the recognition from University Grants Commission (UGC) New Delhi for the purpose of grants. Bharathiar University is named after the great visionary and the revolutionary national poet, Subramania Bharathi, functioning with the motto of “Educate to Elevate” has enabled the University to emerge as one of the strong pillars of higher education in this region. Bharathiar University aims at inculcating necessary Knowledge, Skills, Creative Attitudes and values among the youth to contribute more effectively towards establishing an equitable social and economic and secular ideal of our nation.
The vision of the University is to provide internationally comparable quality higher education to the youth and strives to excel in promoting and protecting the rich heritage of our past and secular ideals of the nation. Bharathiar University has 39 Departments belonging to 13 schools and offers 54 PG courses besides M.Phil. and Ph.D. programmes through these departments. There are nearly 2400 post graduate students and 375 scholars in various departments of the University. The University covers Coimbatore, Erode, Tirupur and Nilgiris districts and is endowed with 133 affiliated colleges and 33 research institutions. Bharathiar University is located in a sprawling area of about 1000 acres free from pollution, 12 km away from Coimbatore city, where the atmosphere is quite serene and ideal for intellectual pursuits. The campus has a number of well-designed buildings which house various teaching and research schools, library, Internet centre, administrative offices, hostels and canteens, etc.

About Us

The Department of Computer Applications, Bharathiar University has its roots from the year 1985 and it is one of the well-known departments in the field of computer applications education and research. The Department of Computer Applications offers MCA, Post Graduate Diploma in Computer Applications, M. Sc. Data Analytics, M. Sc. Cyber Security, M.Phil. and Ph.D. programmes. The Department of Computer Applications is imparting knowledge in the areas of Computer Applications to students by class room based teaching, practical sessions in the computing lab, course work, record work, seminar and industrial project work. The Department emphasizes a shift from mass teaching to personalized instruction, single learning to multiple learning, rigid daily programme to flexible schedules, training in formal skills and knowledge, isolated contents to interrelated, memorial answers to case-study based problem solving.
The department has a team of learned and dedicated teachers to train the students in the latest technologies enabling them to acquire the necessary skills to work in any reputed IT industry. Technical seminars, guest-lectures, personality development programmes, aptitude tests, group discussions, and industrial visits are organized regularly in the department. Value-added courses, soft skill development programmes and job-oriented courses that help to increase the employment potential of the students are being conducted on regular basis. The department is equipped with well-furnished laboratories and spacious class rooms. The excellent infrastructure facilities and the quality IT education offered have been well appreciated by researchers and academicians. The thrust areas of research in the Department of Computer Applications are Integrated Data Modeling, Big Data Analytics, Artificial Intelligence and Optimization techniques, Concurrent Engineering Information Systems, Knowledge Management, Soft Computing, Data Mining, Bio-inspired Computing, Image Processing and Software Engineering.

The Interdisciplinary Cyber Physical Systems (ICPS) division of the Department of Science and Technology (DST), has taken up the networked project – Digital Poompuhar to digitally reconstruct the underwater heritage site which is now a submerged port located 30 km away from the present Poompuhar town. The city was a hallmark of inter - continental trade, social systems, architecture, buildings, and culture and had maritime trades with several far-flung countries around the world. Some of the ancient Tamil literatures infers that Poompuhar was submerged due to the sea-level rise and swallowing up of the land by the sea. About Us However, despite several studies from Tamil literature, archaeology, history, epigraphy, underwater exploration and geosciences, the mystery of the exact location of Poompuhar initially, its age, and shifts, along with periods, time series and spatial evolution in the present location at the mouth of river Cauvery and the reasons and periods of its extinction remain unresolved. DST has set up a network of around 14 eminent academicians, and research institutions in the country to trace the history of the ancient port city Poompuhar, under the Principal Investigator, Prof. S M Ramasamy, Professor of Eminence, Department of Remote Sensing, Bharathidasan University, Thiruchirappalli. A sanction of Rs. 850.563 Lakhs (rupees Eight Crores Fifty Lakhs Fifty Six Thousand Three Hundred only) is granted for the same. The participating institutions are AMET University, Chennai, NIOT, Chennai, Velammal College of Engineering, Madurai, Ranganathan College of Engineering, Coimbatore, CUSAT, Cochin, KLE Technological University, Hubballi, Tamil University, Thanjavur, Bharathidasan University, Thiruchirappalli, Gandhigram Rural Institute, Dindigul, SASTRA University, Thanjavur, Annamalai University, and Bharathiar University, Coimbatore.
The study involves underwater surveys and photography by remotely operated vehicles and sea bed drilling, remote sensing based geodynamic studies to bring out comprehensive information on the time series evolution and extinction. The study also involves the visualisation of geodynamic processes of the last 20,000 years like land subsidence, sea-level rise, Cauvery’s migration, floods, tsunami, cyclones and erosion. The information extracted from the studies will help digitally reconstruct the life history of Poompuhar. The initial studies carried out using the Indian Remote Sensing Satellites LISS IV and GEBCO (General Bathymetry Chart of the oceans) data sets have brought out exciting information, which says that Poompuhar city was initially established in Cauvery delta-A, 30kms away from the present Poompuhar town around 15,000 years ago. It shifted further 10 km to the west to Delta-B around 11,000 years ago and again further 10 km west to delta –C around 8000 years ago. Finally, it was re-established at the present location at the mouth of the river Cauvery around 3000 years ago. The shifts took place due to the continuous rise of sea levels and the submergence of the deltas.
Further studies, using Multi Beam Eco sounder data of the National Institute of Ocean Technology (NIOT), Chennai has led to the discovery of a harbour like structure as well as sea walls and a probable bridge. The harbour like structure is North-South oriented, 10 km long and 3 km broad. These have given new insights about the life history of Poompuhar and the social, cultural, and technological evolution of this part of the country as well as the age of Poompuhar from 3000 years to 15,000 to 20,000 years. The study is also expected to provide packages of scientific information not only on the life history of Poompuhar and the socio-cultural evolution but also the science and technological evolution and the disaster history of this region.
