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.
Cell Phone Operated Robotic Car
(2014) Fakih, Awab
Conventionally, wireless-controlled robots use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls. Although the appearance and capabilities of robots vary vastly, all robots share the features of a mechanical, movable structure under some form of control. The control of robot involves three distinct phase namely perception, processing and action. Generally, the preceptors are sensors mounted on the robot, processing is done by the on-board microcontroller or processor, and the task (action) is performed using motors or with some other actuators. Index Terms— Dual-Tone Multi-Frequency (DTMF), radio control, remote control vehicle, Touch-Tone, Perception, Flash Override
Design and Analysis of a Broadband Monopolar Patch Antenna
(IEEE International Conference, 2014-05) Fakih, Awab
A new low profile and broadband monopolar patch antenna is proposed. Previously, long rectangular patch antennas were proposed that had a compact structure and high gain, but these antennas were designed for broadside radiation. There are some patch antennas that achieve wide bandwidth by employing a thicker substrate. However, its profile may not be low enough for some cases that cover a very low profile space. We propose a low profile patch antenna with wide bandwidth, high gain and monopole like radiation pattern. The proposed antenna has a bandwidth of 9.4% and gain of 7 dBi with monopole like radiation pattern for an infinite ground plane. While for a finite ground plane bandwidth of 12.3% and gain of 5 dBi is obtained. Keywords- Excitation mode; low profile; monopolar patch antenna; coplanar waveguide fed (CPW); omnidirectional; Method of Moments (MoM).
DWDM Link with Multiple Backward Pumped Raman Amplification
(International Journal of Computational Engineering Research, 2013) Fakih, Awab
Faced with the challenge of dramatically increasing capacity while constraining costs, carriers have two options either to install new fiber or increase the effective bandwidth of existing fiber. The technology of dense wavelength-division multiplexing (DWDM) has recently resulted in a considerable increase in the transmission capacity of fiber-optic communication systems up to several terabits per second. The further improvement of the transmission capacity of such systems can be achieved through the expansion of the spectral range of WDM transmission toward the short-wavelength region. Therefore in this report we have proposed and investigated the new trends and progress of fiber Raman amplification for dense wavelength division multiplexing photonic communication networks. Forty individual channels carrying PRBS data are transmitted over a 50 km length of ITU-T G.652 single mode dispersive fiber. The design objective is to utilize distributed Raman amplification to compensate for the link attenuation thereby effectively increasing the inter-EDFA span in a longer-haul link. KEYWORDS: PRBS, Digital Crossconnect System (DCS), phonons, Dense wavelength division multiplexing (DWDM), stimulated raman scattering (SRS), raman amplification, pump evolution, EDFA.
Radio-over-Fiber system using Photonic Active Integrated Antennas (PhAIAs)
(International Journal of Electronics & Communication Technology (IJECT), 2014-03) Fakih, Awab
There is much current interest in low-cost radio-over-fibre (RoF) systems for distribution of mobile-phone and WiFi signals within buildings. In such systems the link gain and packaging cost will be critical. This report describes a low cost scheme for implementing in-building distributed antenna systems using the Photonic Active Integrated Antenna (PhAIA) concept, whereby photonic devices are integrated directly with planar antennas. It is an extension to Active-Integrated-Antenna (AIA) concept from microwave engineering field. The fact that the photonic device and antenna are highly integrated means that very efficient impedance matching can be achieved, which can lead to improved link gain. It could also lead to much reduce packaging and fabrication costs.

Real-Time Whiteboard Capture System
(IOSR Journal of Electrical and Electronics Engineering (IOSRJEEE), 2012) Fakih, Awab
Real-Time Whiteboard Capture System captures whiteboard lecture video in real time and extracts newly written pen strokes. Unlike other systems, it does not require special instruments such as electronic pen or whiteboard. The captured video images are classified into pen strokes on the whiteboard, foreground (person in front of the whiteboard) and Whiteboard Background Model (whiteboard without the text). The newly written pen strokes are extracted from current image frame and updated to the Whiteboard Background Model. Whiteboard Balancing is done where the colour of the whiteboard is corrected and made completely white. The captured video is processed at 8 frames per second (fps) instead of 25 fps that is output from the camera. Whiteboard balancing and reducing the processing frame rate provide a reduced bandwidth when transmitting whiteboard contents to remote meeting participants. This system can be used in conjunction with other teleconferencing tools such as voice conference and application sharing to improve online meeting experience. Keywords: Whiteboard, real-time, luminance, pixels, archiving, foreground, bandwidth.
RFID Based Smart Shopping and Billing
(International Journal of Advanced Research in Computer and Communication Engineering, 2013-12) Syed, Zeeshan Ali
The advent of wireless technology along with other communication techniques has helped in making electronic commerce very popular. A modern forward looking product is the one that aids the comfort, convenience and efficiency in everyday life. In this paper, we discuss an innovative concept of RFID Based Smart Shopping and Billing. The key idea here is to assist a person in everyday shopping in terms of reduced time spent while purchasing a product. The main goal is to provide a technology oriented, low-cost, easily scalable, and rugged system for aiding shopping in person. The developed system comprises of Cart location detection unit (CLDU), Server Communication unit (SCU), User Interface and display unit (UIDU) and Billing and Inventory management unit (BIMU). CLDU is used to smartly locate the position of shopping cart inside the shopping market to help in obtaining relevant product information. SCU will help in establishing and maintaining the connection of the shopping cart with the main server. UIDU will provide the customer with user interface and BIMU deals with the billing and inventory management in collaboration with the SCU. These units are integrated into a smart enclosed system and are tested to satisfy the functionality. The smart shopping cart will help shorten the checkout lines thereby helping the customers at retail stores. The customers will be able to scan the items themselves and the LCD screen on the shopping cart will keep updating the total. This will turn out to be very beneficial for the retail stores as more people will enjoy the shopping experience and come more often to shop.

Electronic Commerce has become extremely popular with the rise in wireless technologies and other communication techniques. Purchasing and shopping at big malls is becoming daily activity in metro cities. There is a huge rush in such places during weekends and holidays. People purchase different items and put them in trolley. After completion of purchases, one needs to go to billing counter for payments. At the billing counter the cashier prepares the bill using bar code reader which is very time consuming process and results in long queue at the billing counter. A smart product is the one that aids the comfort, convenience and efficiency in everyday life. In this paper, we discuss an innovative concept of Intelligent Smart Shopping and Billing. The key idea here is to assist a person in everyday shopping in terms of reduced time spent while purchasing a product. The main goal is to provide a technology oriented, economical, easily scalable, and rugged system for aiding shopping in person.

(International Journal of Electronics & Communication, 2014-05) Ravindra, Chaya; Khatik, Ramjan; Pathan, Siraj; Nawaz, Banda
Subband coding decompose the input signal into different frequency bands .After the input is decomposed to its constituents, we can use the coding technique best suited to each constituent to improve the compression performance. Decompose a signal into components by applying frequency-selective filtering. Then select the best coding technique that best suits each component (subjectively and objectively). Subband coding applications are Speech coding ITU-T G.722 Encode high-quality speech at 64/56/48 kbps. Interest in signal processing long predates computers. As long as people have tried to send or receive information through electronic media, such as telegraphs, telephones, television, radar, etc., there has been the realization that these signals may be affected by the system used to acquire, transmit, or process them. Sometimes these systems are imperfect and introduce noise, distortion, or other artifacts. Understanding the effects these systems have and finding ways to correct them is the foundation of signal processing . This paper depicts analysis side of the system implemented using freeware language SCILAB. The synthesis side includes speech production The digital filters have been implemented for extraction feature .The signal processing application of SCILAB has become boon.
