    Blood cell monitoring based on FPGA, implemented using VHDL
    (Journal of Research in Engineering and Applied Sciences, 2017-10) Khan, Zarrarahmed; Pathan, Siraj; Pathan, Riyaz; Ali, Zeeshan; Khadase, Rahul; Alvi, Rizwan
    This paper showcases a system in the medical field which will assuage the limitations in today's blood cell monitoring since everything will be done digitally. Our work is a combination of image processing and its implementation in hardware. This system will not only store the information of patients' blood components, but it will also indicate the deficiencies using an Alert signal. Area wise storage of patients' information will help in Area Wise Analysis of data. This blood cell monitoring system is designed on Xilinx ISE 14.6 using VHDL and implemented on Spartan 3A based FPGA (Field Programmable Gate Array). In medical camps it is very difficult to test blood samples of thousands of people with pharmaceutical techniques and at that time this Blood Cell monitoring system will give proper ease to test blood samples as it will require few microscopic pics only and image processing will be done at ultra-high speed since we are using the FPGA. FPGA will itself process images, store relevant data and display them in proper fashion.

    Elevator model using controller and AC drive
    (AIKTC, 2017-05) Alvi, Rizwan; Ukaye, Abdul (14DET65); Naziri, Umair (14DET98); Khan, Sajid (14DET86); Shaikh, Ibrahim (13ET50)
    We are making a elevator model to overcome accuracy and efficiency in the past elevator model. Previously if elevator car moves from one floor to other, then the speed would remain the same throughout from source to destination which use to result in the sensing of jerk which was very annoying and harmful to devices (to tension rope, etc.). To achieve speed control of motor and smooth flow, we are using variable supply and frequency (VFD) by which the speed of motor is gradually varied according to kind of operation. Different sensors are also used to sense the velocity, load and position of elevator car. A controller is also used to ensure safety, VFD is also controlled through controller, it operates according to the commands from the controller (like transit time, max speed, etc.)

    Fingerprint enhancement using different techniques
    (AIKTC, 2016-05) Alvi, Rizwan; Khan, Misbahul (11ET10); Momin, Mohd. Ameer (12ET39); Shaikh, Mubarak (12ET52)
    Existing security measures rely on knowledge-based approaches like passwords or token based approaches such as swipe cards and passports to control access to physical and virtual spaces. Though ubiquitous, such methods are not very secure. Tokens such as badges and access cards may be shared or stolen. Furthermore, they cannot differentiate between authorized user and a person having access to the tokens or passwords. Biometrics such as fingerprint, face and voice print offers means of reliable personal authentication that can address these problems and is gaining citizen and government acceptance. Fingerprints were one of the first forms of biometric authentication to be used for law enforcement and civilian applications. In this thesis, we introduce a new approach for fingerprint image enhancement based on the Gabor filter have been widely used to facilitate various fingerprint applications such as fingerprint matching and fingerprint classification. Gabor filters are band pass filters that have both frequency-selective and orientation-selective properties, which means the filters can be effectively tuned to specific frequency and orientation values. The proposed analysis and enhancement algorithm simultaneously estimates several intrinsic properties of the fingerprint such as the foreground region mask, local ridge orientation and local frequency.

    Gesture based wireless single-armed robot in cartesian 3D space using kinect
    (AIKTC, 2015-05) Alvi, Rizwan; Memon, Md. Farhan Md. Fareed (11ET33); Quraishi, Imran Akram (11ET41); Shaikh, Bilal Anees (12ET86)
    Human Machine Interaction (HMI) has always played an important role in everybody’s life motivating research in the area of intelligent service robots. Conventional methods such as remote controllers or wearables cannot cater the high demands in some scenarios. To overcome this situation, the challenge is to develop vision-based gesture recognition techniques. This project describes our work of controlling an Arduino based wheeled, one armed robot, used as a prototype, controlled through various gestures of the arms and legs. For gesture recognition, we make use of skeletal tracing ability of Kinect – a product of Microsoft. Bluetooth is used to make the controls wireless. Since it is not line of sight operation, the robot also captures the environment video and transmits it over radio frequency in real-time and displayed on the screen. On the user end, according to the received video, the operator guides the robot and uses the arm to pick and place objects with the help of predetermined gestures.

    Since the increment in competition .firms have to manage and evaluate customer interactions. Here customer segmentations plays a vital role and which is necessary for this competitive environment. The most common way to segregate one customer to another is to promote a group of customers into standard and premium customers. This segregation will helps to enhance customer relationship management. Here manually segmented data is analyzed. with the analyzed data firms starts identifying the customers true value and loyalty . since customers loyalty and value can provide basic data to focus more on personalized marketing. Customer life time value (CLTV) is known as an important concept in marketing and management of organization to increase the captured profitability. Total revenue generated by a customer during His/hers lifetime is named customer lifetime value. The generated value can be calculated through different methods. Each method considers different parameters. Due to the industry , firms , companies the parameters of CLTV may vary. In this article we review most presented models of calculating CLTV.

    (AIKTC, 2018-05) Alvi, Rizwan
    This project will present a model of a virtual laboratory of computer networks, carried out with simulation tools such as GNS3 and its libraries. GNS3 will allow us to imple- ment and simulate the topology close to real topology in the real laboratory, it also helps in virtualization of new topologies easily and quickly and economically. We will design and implement new virtual topologies to test more advanced concepts such as bridging, dynamic and adapted routing, load balancing between routers and other device networks or NAT con gurations (Network Address Translation). GNS3 allow us to test di erent con gurations changing the addressing and routing information, analyzing Internet data tra c anywhere in the topology or control the network security adapting the con gura- tions of access lists in the routers. In this paper we will use Wireshark. Wireshark is a packet analyzer integrated in GNS3 used to capture, sni and analyze data packets according to both used protocols and encapsulated information on virtual Ethernet or serial interfaces.

    Review on secondary and tertiary control structures for Microgrid
    (International Journal of Computer Sciences and Engineering, 2018-03-30) Qureshi, Tahoora; Alvi, Rizwan
    Abstract— With the large scale integration of Distributed Energy Resources (DERs) into the existing power system, there has been a significant impact on the operation of distribution networks; the major impacts being power quality problem along with congestion and voltage regulation issues. This demands coordinated control approaches which allow Distributed Generation (DG) units to actively participate in voltage and frequency regulation. To realize the same, hierarchical control structures constituting the primary, secondary and tertiary control structures are implemented. These controllers are classified as the centralized or the decentralized type. Thus by employing droop controls or impedance based controls desirable outcomes such as power sharing, non linear load sharing and harmonic reduction is possible thanks to coordinated operation of secondary and tertiary control layers with primary or local layer. This paper aims at establishing a basic understanding of these control layers as applied to AC and DC microgrids along with detailed explanation of modified structures from the conventional control structures in a typical microgrid.
