Instrumentation and USIC

Department of Instrumentation & USIC started as University Science Instrumentation Centre (USIC) in 1978 under USIC scheme of University Grants Commission (UGC) in the department of Physics, GU. It became a full-fledged department in 1986. The main building of the department was constructed with grants from UGC and was inaugurated by the then Hon-ble Chancellor of GU Sri Bhisma Narayan Singh on 13th August 1988. The department was recognized as an academic department in 1987 by the Academic Council, GU.

The Post Graduate Diploma in Instrumentation (PGDI) course was started in 1987-88 and was the first such course in the entire NE region which trained qualified engineers and scientists to gain experience in the field of instrumentation. Seventy Five (75) students have passed out PGDI and many of the PGDI passed students are employed in the industries like Oil India Limited (OIL), Gauhati Refinery, Numiligar Refinery etc.

The department through it's repair and maintenance wing has been rendering services in the field of operation, repair and maintenance of various instruments not only to the departments of this university but also to affiliated colleges and other public and private organizations of the NE region. The center has also successfully completed a number of training programs on repair and maintenance of scientific equipment, glass blowing and use of mechanical workshop equipment. A large number of jobs have been done by the repair and maintenance wing of the department and there by has saved considerable amount of GU exchequer. A considerable amount has been earned from outside institutions by rendering repair and maintenance services. Some of the outside institutions that have availed of repair and maintenance services of the department in past are Handique Girls College, B Barooah College, Forensic Science Lab, Assam and Meghalaya, NERIST, Royal Bhutan Polytechnic, Sherbutse College, Bhutan, Statefed Tripti Vanaspati Plant, Gauhati Medical College & Hospital, Assam Engineering College, Indian Institute of Technology, Guwahati etc.

The department has been rendering training to persons deputed from outside institutions from time to time. Trainees deputed from NEHU & IASST were trained in the department and revenue has been earned through such training. The department has organized workshops, seminars etc. from time to time. A two weeks training Programme in Electronics and Instrumentation was organized in 1988-89. Another workshop on Repair and Maintenance of Laboratory instruments for college teachers was organized in 1992. The department hosted the National Symposium on Instrumentation ( NSI-17) in 1992.

At present the practical classes of Workshop Practice of GUIST and MSc Instrumentation are conducted in the workshop of the department.

Sophisticated Analytical Instrument Facility (SAIF), sponsored by Department of Science and Technology, Govt of India was established in 1986 as a Regional X-ray Facility in the department to cater the need of scientific community from research, academic and industrial organizations. SAIF is rendering analytical services in the field of X-ray Diffractometry (XRD), X-ray Fluoroscence Spectrometry (XRF) and Single Crystal X-ray Diffractometry. SAIF has been regularly participating in the rounds of International Proficiency Test for Analytical Geochemical Laboratories conducted by International Association of Geoanalysts (IAG) and has so far organized six workshops on Theory and Practices of XRD, XRF and SCXRD.

The name of the department was changed to Department of Instrumentation & USIC in 2005 and MSc in Instrumentation course was introduced with effect from 2004-2005. This  Course has been renamed as MSc in Instrumentation and Applied Physics with modifications in the previous syllabus.

1. Machine Sensing and Artificial Intelligence based stress diagnosis of plants.
Plants being verbally mute to abiotic and biotic stress factors, offers visual and olfactory response to these stresses affecting their health. Visual responses include change in physical properties viz. colors, size, shape, while olfactory responses includes changes in Volatile Organic Compound (VOC) emission. The Research aims at analyzing these specific responses using machine sensing technique which are otherwise illegible for human perception.
The research group have converged on Machine olfaction technique for sensing the VOC emission profile alteration on stress affected plants, using array of gas sensors, colloquially called “e-nose”. Sensor responses acquired by the data acquisition system developed are put through Machine Learning based decision making classifier algorithms to predict the stresses present in the plant.

2. Implementation of Instrumentation for Process Condition Monitoring in Tea Factory and Study it’s Impact on Tea Quality

Tea quality is influenced by several factors of tea processing stages. The biochemical reactions start just after the plucking of leaves from the bush. So the quality control in the processing stages becomes an important issue to get good quality end product. The main quality attribute of tea is developed in these stages, so the conditions in these stages should be maintained at optimum level.

This group aims to develop the instrumentation needed to monitor different process conditions like moisture content of tea leaves at withering stage, temperature and relative humidity of fermentation and Dryer temperature etc. In the second phase of this study, the process parameters are correlated with the final tea quality to get the optimum process conditions.

3. Studies on Implementation of instrumentation for precision horticulture
Agriculture mainly depends on the atmospheric conditions and changes over time. To understand the past, present and potential future climate conditions, there should be a meteorological database. To do this, a high quality and low cost system, which can give the required dependable database in a standard format is designed. After analyzing the data gathered, stored, viewed from the system, a profitability decision with less risk in farm management can be taken.

This group works on developing a low cost, reliable and user friendly wireless sensor network for collection of relevant physical parameters for precision horticulture and based on the collected data, decision is taken for best management practice of the farm.

4. Piezoelectric based MEMS energy harvester
Microelectromechanical system (MEMs) piezoelectric devices are used to scavenge energy from wasted vibration sources. Such devices are performed to convert energy from mechanical domain to electrical energy. The advancement in the invention of the devices that does not require replaceable power supplies has attracted for researches.

Our team are working on piezoelectric MEMS energy harvester. The main focus of our research is to optimize power from piezoelectric array configuration and optimization of cantilever shape configuration for absence of proof mass of cantilever which results in the reduction of the size of harvester. The most important strategy of future designing MEMS vibration energy harvester is to obtain maximum power with maximum bandwidth at low-frequency vibrations.

5. Study and Measurement of Some Physical Changes of Different Wood Samples Due To Changes in Ambient Condition

The study of physical properties of wood is most essential in the design of wood products. The measurement of physical properties of wood provides an impact in wood technology. The contribution of these measurements provide for selection of wood in engineering applications. It also indicates the quality of wood. To use wood to its best advantage and most effectively in engineering applications specific characteristics or physical properties must be considered. The versatility of wood is demonstrated by a wide variety of products.A precise measurement system is required for the study of physical properties of wood. To study the physical properties of wood with relative humidity a precise measurement is essential. In this work a measurement system is designed, developed and calibrated. The system has the capability to measure simultaneously ambient temperature, relative humidity and physical properties of the wood sample. The physical properties of the wood samples are measured in terms of strain developed on the surface of the samples due to change in relative humidity.

6. Hardware Design & Modelling Techniques for Ground Penetrating Radar (GPR)

 The aim of this research is to create a robust, user-friendly and advanced Ground Penetrating Radar (GPR) processing system using the latest hardware and signal processing techniques.
The work will primarily focus on
  •  Design and fabrication of highly efficient, high gain, low profile wideband antennae for use with our GPR system.
  • Compare the efficiency of existing techniques and study of continuous wave and pulsed RADAR systems.
  • Use and development of advanced simulation tools and data interpretation tools.
The work will enable other researchers and scientists to benefit directly from the results, innovations and advanced processing algorithms. This will allow the GPR community, to easily create and run such models for further improvement of the project’s results. We hope to develop better GPR modelling frameworks which will increase our ability to model GPR data in greater detail and accuracy.
Primary application of our research will be in the use of Non-Destructive Testing used for quality assessment and inspection of key infrastructure elements such are buildings, roads, railways and Geophysical probing of archaeological sites and monuments.
