Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Design of high speed and low power clock controlled flip-flop in 90 nm CMOS technology
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Joshi, Vijay; Tomar, Abhishek
    Increasing processor speed demands peripheral devices of high speed and low power consumption. Power consumption can be reduced by decreasing capacitance of the circuit. Proposed clock blocked flip-flop (CBFF) design uses only 11 transistors and blocks data path after a fixed time. This time can be controlled by delay of inverter used. As data path is open only for small time, power dissipation decreases. Proposed CBFF can be used for large serial data as data loading is limited to two transistors in the design. Low clock load is achieved as only two clocked transistors are used. As there is no need of refreshing circuit when data is changed, PDP is improved. Proposed flip-flop only uses static ratio insensitive differential latch (SRIS), thus achieving complementary output nodes with reduced loading. Cadence Virtuoso tool is used for simulations. In comparison to sense amplifier based flip-flop (SAFF), modified SAFF, Strollo’s flip-flop and self-blocking flip-flop (SBFF), speed and PDP is improved by more than 20 and 15% respectively.

    Frequency notched UWB antenna with switch shaped CSRR and modified line feed
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Goswami, Pankhudi; Paras
    Electromagnetic Metamaterial Antennas offer Ultra wide band, reduced size because of the EM properties offered by metamaterial. The unique property of metamaterial is due to the negative ԑ & μ parameters and negative refractive media in operating frequency band. The interference offered in UWB Antennas, is due to the pre existing bands which is the major area of concern. To minimize the effect of interference, band notched characteristics are used. The proposed antennas namely Antenna I & II, have been designed by using Transmission line model equations. Antennas of substrate size of 40mmx40mm, having resonant frequency at 3 GHz and on the 1.58 mm height of substrate. The substrate material used is FR4 having permittivity of 4.4 and loss tangent of 0.02. The circular patch having optimized radius of 13.57 mm is used. The proposed antenna I has a combination of conducting wire and switch shaped CSRR structure at ground plane to obtain metamaterial characteristics. The wire structure has been used to achieve the negative permittivity and switch shaped ring resonator to achieve the negative permeability and hence in the desired frequency band, resonance is achieved with the help of combined structure. The UWB is obtained by taper feedline and with the increased bandwidth range (2.7-20 GHz), interference increases. Therefore, Antenna II is proposed with circular slots on the patch by which the band reject characteristic has been achieved. Antenna II rejects WIMAX band range. Measured results show that there is Ultra Wideband ranging from 2.7- 20 GHz with bandwidth of 17.3 GHz. The simulated peak gain of near 9.3 dB has been obtained. There is a good agreement between the simulated and measured results. The proposed antenna has reduced size, having ultra wideband as compared to previously fabricated antennas. The proposed antenna has application in wireless applications

    Design of hybrid style full adder for low power and high speed application in 0.18μm CMOS technology
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Adhikari, Shivam; Tomar, Abhishek
    In the latest digital logic designs, the major challenge is power consumption. In current high speed processors, large amount of power is dissipated in the datapath. Researchers are trying to reduce this power consumption from more than a decade. By using effective topology for logic implementation and transistor count, this problem can be reduced significantly. In the present proposed work a new 18-transistor adder cell has been proposed and implemented in hybrid logic style. The proposed adder cell is compared with previous reported conventional and hybrid adder cells in 0.18μm CMOS technology and parameters like delay, average power consumption and power delay product are compared. The simulation is performed using cadence electronic design automation (EDA) tool. Power delay product of proposed adder is 1.84fJ has been obtained which is smaller than the previous proposed conventional and hybrid adders. The result shows 30% improvement in power delay product in the proposed adder. The reduction in power delay product is due to high speed XOR-XNOR circuit and small propagation path for sum and carry. The proposed adder cell shows the delay of 66.4ps, which is lesser than the previous adders. The proposed adder shows the improvement and provides a solution for the high speed digital circuits.

    Target vehicle tracking under occlusion for video surveillance
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Joshi, Rakesh Chandra; Mathur, Sanjay
    With the rapid development corporate infrastructure, industrial establishments, educational institutes and residential premises are facing an increasing need to enhance their security. In this thesis, a hybrid target vehicle tracking algorithm for smart video surveillance is proposed. It aims to track an unidentified target vehicle’s motion in a secured campus even in case of occlusion (if any) and to detect if it exhibits any suspicious activity. The main contents of this thesis are as follows: Aiming at the tracking of a target vehicle and handling occlusions if any through Kalman Filter assisted occlusion handling technique, performance evaluation under different noise and illumination levels and finally suspicious activity detection technique for the tracked vehicle. The algorithm works through two periods namely tracking period (no occlusion) and detection period (in case of occlusion), thus depicting its hybrid nature. Kanade-Lucas-Tomasi (KLT) feature tracker governs the operation of algorithm during the tracking period, whereas, a Cascaded Object Detector (COD) of weak classifiers, specially trained on a large database of cars, governs the operation during detection period or occlusion with the assistance of Kalman Filter. The motion analyses and suspicious activity detection capabilities have been discussed separately. The algorithm’s tracking efficiency has been tested on six different tracking scenarios of increasing complexity in real time. Performance evaluation results under high noise and low illumination show that the tracking algorithm has good robustness. All tests have been conducted on the MATLAB platform. The validity and practicality of the algorithm are verified.
