    (K.K.Wagh Institute of engineering education & research, 2019-06-08) Khan, Tabrez; Magar, Rajendra; Ansari, Zakir; Shaikh, Afzal
    Academic audit is a methodical and scientific process of designing, implementing, monitoring and reviewing the quality in academic systems in higher education. The academic audit provides a strategic planning and its implementation for the teaching learning activity in the institute. In order to ensure quality and effective curriculum delivery, in teaching-learning, quality assurance system like Internal Academic Audit (IAA) system is very much essential. This paper aims to discuss the effective implementation of IAA in the technical campus situated in Panvel, Maharashtra. Academic Audit is done thrice during the term as Pre Term Audit- before the commencement of the term, Mid Term Audit- during the mid of the term and Post Term Audit- after the term end. Total thirty four numbers of input parameters are identified based on which academic audit is carried out. For every single parameter in the audit format, the course owner is evaluated for complete, partially complete and incomplete status of that parameter as per defined rubrics.The score of all the parameters is converted to a scale of 5 which would become the score of that course owner and would be used for appraising the concerned course owner.The reports of the Pre Term, Mid Term, and Post Term audit would be kept with the audit team and the necessary corrections would be conveyed to the respective course owners at the time of the audit. It was observed that after the introduction of the aforementioned process, the academic files of all the faculty members were found complete in all respects and quality of assignments, teaching learning and evaluation process was improved significantly.

    Advance driver assistance system
    (AIKTC, 2015-12) Shaikh, Afzal; Kazi, Emad; Patel, Arsalan; Salunkhe, Abhijeet (11ET45); Khedekar, Mustakim
    In the current scenario, the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. In order to make roads safer, cleaner and smarter, sensor and communication technologies are increasingly considered in research, standardization and development. While today‘s vehicles are already able to sense the surrounding environment, we expect that future cars will communicate with a roadside communication infrastructure and with each other. Connected vehicles create a fundamental building block of Intelligent Transport Systems (ITS) and can provide numerous application services to improve safety and comfort of driving. These accidents can be avoided if only if there was a mechanism to alert the drivers of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. Vehicle-to-vehicle communication can prevent crashes. Smarter cars that talk to one another are the next step in auto safety. Wireless, vehicle-to-vehicle communication systems warn you of potential hazards. This is prime aim of our topic. In this topic, we propose the use of Bluetooth & Ultra Sonic Motion Sensor Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving many lives.

    (AIKTC, 2020-05) Shaikh, Afzal; Surve, Zaid (15DET113); Khan, Faraz (15ET19); Ansari, Saddam (16DET75); Khan, Mohammad Ibrahim (16DET94)
    A reversible logic gate is a gate in which the output is guaranteed, but the input is not confirmed, in other words, reversible functions are those that perform permutations of the set of input vectors. Reversible Gates are circuits in which outputs are equal to the number of inputs, and there is one to one correspondence between the vectors of inputs and outputs. Reversible logic circuits have emerged as a promising technology has deficient power consumption with high speed and less delay, which is in demand with the increasing universal growth. Reversible logic Gates have its application in low power CMOS, Quantum Computing, Nanotechnology, and Optical Communication. As we know, the Reversible logic circuits deal with low power consumption with high speed and less delay we are going to design and analysis of 16-bit Full Adder using Reversible logic gates, and we need to observe the result and compare with conventional logic gates and observe the essential parameters between both designs.

    (AIKTC, 2016-05) Shaikh, Afzal; Shaik, Abdul (12ET44); Shaikh, Irfan (12ET48); Shaikh, Mohamedbilal (12ET51); Shemna, Neehal (12ET57)
    In high performance analog circuit, it is a very challenging task to design a high performance complemtary metal oxide semi-conductor, which is used in either ADC or DAC. As we are dealing with high performance circuit, to meet these requirement both accuracy and fast settling of system is needed, OP-Amp with high DC gain frequency can satisfy both of these requirement. Although a Op-amp with high DC gain satisfy these requirement, but still in many aspects which leads to complementary demands, as the intrinsic gain of many devices are limited. OTA is an Op-amp without an output driver. It is capable of driving small capacitive load. These makes OTA a well suitable for pipeline application.The whole procedure is focused on the development of ultra low power amplifier requiring low silicon area but been able to drive high capacitive load.

    (AIKTC, 2015-05) Shaikh, Afzal; Vanu, Faizan; Shaikh, Mohammad; Khan, Aftab
    The research in wireless communication has spurred the development of extra ordinary range of antennas, each with its own advantage and limitations. In today’s modern communication industry, antennas are the most important components required to create a communication link. Microstrip antennas are an urgent need for aerospace and mobile applications because of their low profile, light weight, flexibility to efficiently combine the capabilities of multiple antennas and low power handling capacity. Conventional Microstrip patch antennas has some drawbacks of low efficiency, narrow bandwidth of the central frequency, its bandwidth is limited to a few percent which is not enough for most of the wireless communication systems nowadays. The project provides a detailed study of the design of coaxial-fed Rectangular Microstrip Patch Antenna to facilitate dual polarized, dual band operation. The design parameters of the antenna have been calculated using the transmission line model and the cavity model. For the simulation process HFSS (High Frequency Structural Simulator) which is electromagnetic software based on finite element method (FEM) has been used. The effect of antenna dimensions and substrate parameters on the performance of antenna have been discussed. The antenna has been designed with embedded spur lines and integrated reactive loading for dual band operation with better impedance matching. The designed antenna can be operated at two frequency band with centre frequencies 2.44 GHz (Bluetooth) and 5.5 GHz (Wi-Fi). So the dual band and dual frequency operation has successfully incorporated into a single patch.

    (AIKTC, 2016-05) Shaikh, Afzal; Khan, Mohd. Haris (12ET29); Kazi, Mohd. Saad (12ET37)
    In this project we are going to study about Landslide warning system, as the occurrence of landslides is a big loss for human life and property. We can’t stop the natural causes but we can be alert before they occur. So for alerting people from landslides we use this technique. In this design we have used three sensors of Angle sensor which gives the readings of slope angle if there is any movement in landslide and we have Liquid level sensor it collects the depth of water at the mountains. Temperature sensor gives the changes in the temperature. These all nodes of sensors are connected to the Raspberry pi for collection of data. As the data is collected then all the readings are given to Zigbee for transmission. As we obtain the information at the receiver side by LCD display at receiver station or by SMS we can alert the people and save lives and property. Thus this project is very important as we use it in our real time purpose for saving lives and property. This design combines of wireless communication technology and Wireless Sensor Network.
