Title: FPGA-based Implementation of Galois Field Arithmetic
Authors: Kinny Garg and Dr. J.S. Sohal
Abstract: Error control coding for detecting and correcting errors in digital signals has assumed utmost importance in the modern world. This paper proposes a novel way to implement the Galois field arithmetic, the cornerstone of error-control coding, on Field Programmable Gate Arrays (FPGAs) using Verilog hardware description language (HDL). In this paper, we develop and implement the Galois Field arithmetic operations such as multiplying two elements, converting an element from primitive element power form to cartesian (or vector) form and vice-versa, and finding the inverse of an element, on FPGA. Error control coding is a good candidate for FPGA-based hardware implementation because FPGAs come with the advantages of reconfigurability, reprogrammability, design flexibility, reduced development times, and speedy operations.

Title: Design and Analysis of Low-Voltage Low-Power Tri-state Buffers and its Application using 22-nm CMOS Technology
Authors: M. Madhusudhan Reddy, M. Sailaja and K. Babulu
Abstract: In memory architecture, the standard Complementary Metal Oxide Semiconductor (CMOS) and clocked CMOS (C2MOS) tri-state buffers lie in the critical path that affects the overall speed of the memory. The standard CMOS and C2MOS logic based tri-state buffers require 12 and 8 Transistors. The internal circuitry in tri-state buffer is responsible for the huge time-delay and more power. Two novel tri-state buffer circuits have been proposed. They are Transmission Gate (TG) based tri-state buffer and pseudo-nMOS with active enable pull-up tri-state buffer, designed and examined using mentor graphics tool at 22-nm CMOS technology. The proposed tri-state buffer circuits are compared with existing ones by varying the supply voltage in the range of 0.4V-to-1V. The optimization of transistor count leads to the reduction of logical effort (G) and parasitic delay (p) of the circuit. The proposed TG tri-state buffer occupies less delay of about 47% and 31.8% when compare to existing ones for all considered supply voltages. The stacking effect contributes to reduced static power of about 36% and 33% using TG tri-state buffer as compared to CMOS and C2MOS. The proposed TG tri-state buffer exhibits high speed and low power-delay-product (PDP) of about 72% and 66% as compared to existing ones. By using Euler’s path approach, optimization of an area takes place by the TG logic based tri-state buffer by a factor of about 72.62% and 44.44% as compared to standard CMOS and C2MOS tri-state buffers.

Authors: Kaustubh Bhattacharyya, Rima Deka and SunandanBaruah
Abstract: Automatic target recognition (ATR) in RADAR with very high frequency signal (Terahertz range) is increasingly becoming important primarily for modern defense strategy. Signal processing plays a vital role for extracting the appropriate information (features) to train a soft computing tool such as Neural Network and Fuzzy. The recognition rate of such tools is heavily dependent on the extracted feature. In this paper, an efficient method of target recognition at terahertz frequencies using recurrent neural network (RNN) and adaptive Neuro-Fuzzy interference system (ANFIS) is presented. The ATR algorithm is supported by some efficient signal processing techniques to extract the features of the target. The method adopted for feature extraction in this work is wavelet decomposition. A comparison between RNN and ANFIS for target recognition was made and it is reported here that the ANFIS provides better recognition rate than RNN for target recognition in terahertz frequency.

Authors: Ramneek Kaur Brar and Harpal Singh
Abstract: The protection of multimedia contents has turn out to be a crucial problem with the explosive expansion in the development of electronic commerce and online services. Watermarking is one of the most widely used technologies to tackle this problem in which a watermark is added to the original multimedia in such a way that it must not cause serious degradation of the original digital media. A good watermarking algorithm must satisfy three criteria: the lawful ownership security, sturdiness in opposition to the image manipulations, and imperceptibility of the watermark. In this paper, we have reviewed the theoretical analysis of various watermarking techniques in wavelet domain. In addition, a brief discussion on the properties of watermarking systems, wavelet domain, watermarking attacks, various domains of watermarking and robustness and security considerations for digital watermarking has been presented. With extensive research in the field of digital image watermarking, we find a huge scope in the development of novel watermarking techniques by hybridization of various transforms.

Abstract: For both domestic and industrial applications, the BLDC motor is widely being used. They are popularly used due to its reliability, controllability and compact size. BLDC motor is normally operated with one or more rotor position sensors or position encoders. This paper provides exceptional Sensorless strategies for Permanent Magnet Brushless DC (PMBLDC) motor. The BLDC automobiles have an internal stator again EMF that is trapezoidal waveform with the help of this BEMF the method is proposed. This proposed technique will gives a wide range of speed. The indirect BEMF are two types they are third harmonic voltage detection and BEMF integration method. In 3rd harmonic BEMF method, the back EMF component is extracted from phase voltages (stator), third harmonic signals was filtered and it is fed as triggering pulse for the inverter. Even though this method provides a better speed performance than exiting one, it requires heavy filtering devices and a power quality issue arises. To overcome all these we are going for the Indirect BEMF integration method. In this method, the BEMF are extracted from the stator and it was send across the conditioning & integrating circuit to reduce the PQ issues. This method provides as wide range of speed control, reduced PQ disturbance and better efficiency. But, the dynamic performance of the method is not effective. So we proposing Direct BEMF method, which is highly effective than that of indirect methods. The simulation results of these methods are discussed in the below chapters. The simulation for proposed systems are done using MATLAB/SIMULINK software package (R 2014).

Title: Slotted T shaped ultra wideband microstrip patch antenna for wireless applications
Authors: Nagabhushana H M and Vishnumurthy T D
Abstract: Miniaturized slotted T shaped ultra wideband microstrip patch antenna is presented in this paper for wireless applications. The proposed antenna consists of a variable sized T shaped radiating patch with four rectangular slots etched on the plane of the patch as well as on the ground plane. Slots are taken on the patch for wideband characteristics. The designed antenna also uses the concept of fractal geometry for wideband characteristics and partial ground for impedance matching. The proposed antenna design is analyzed using different substrates like FR-4, Duroid and Glass. The optimal results are obtained with the FR-4 substrate with dielectric constant 4.4. The proposed antenna is fabricated on FR-4 epoxy (er=4.4) substrate of thickness 1.6 mm and tangent loss d=0.01. The feeding to the antenna is by 50 O microstrip line feeding. The antenna satisfies the ultra wideband characteristics and can be useful in many wireless applications. The slotted T shape is obtained from the basic rectangular patch antenna of size 17 x 15 x 1.6 mm3. The slotted antenna has been simulated using HFSS v.15 Software, fabricated on FR-4 substrate and the parameters like return loss, VSWR, gain and radiation pattern are measured using network analyzer and anechoic antenna measuring unit. The measured and simulated results are very much similar in all responses. The simulation results show that the antenna resonates at 4.35 GHz, ranging from 2.75 GHz to 10.65 GHz and hence suitable for wideband applications. Many wireless devices such as 3.6/4.9/5/5.9 GHz WiFi, 3.41/3.49 LTE, 3.5/5.5 GHZ WiMAX, 4.2-4.4 GHz Radio Altimeter, 5.2/5.8 GHz WLAN, 7.05-7.075 GHz Satellite Radio Uplink, 5.15-5.35 GHz HiperLAN, 3.7-4.2 GHz C-Band, 8.5-10.68 GHz X-Band and 3.3/3.4 GHz proposed 5G applications can use this proposed antenna. The radiation patterns and return loss are omnidirectional with moderate gain. The size reduction of the antenna is by etching of slots on the patch and partial ground concept. The overall antenna size is reduced around 41.33%. The simulation and measured results are closely related to each other

Title: A Comparative Study on Brain Tumor Segmentation
Authors: C.Jaspin Jeba Sheela and G.Suganthi
Abstract: Human brain tumor segmentation systems can enhance the diagnostic capabilities of physicians and reduce the wastage of time for accurate diagnosis. Brain tumor segmentation is one of the most challenging and time consuming tasks in medical image processing. MRI (Magnetic Resonance Imaging) is a medical technique, mainly used by the radiologist for visualization of internal structure of the human body without any surgery. MRI provides plentiful information about the human soft tissue, which helps in the diagnosis of brain tumor. Accurate segmentation of MRI image is important for the diagnosis of brain tumor by computer aided clinical tool. After appropriate segmentation of brain MR images, tumor is classified into malignant and benign, which is a difficult task due to complexity and variation in tumor tissue characteristics like its shape, size, gray level intensities and location. Taking into account the aforesaid challenges, this research is focused towards highlighting the merits and demerits of earlier proposed classification techniques discussed in the contemporary literature. Besides summarizing the literature, segmentation analysis brings forth a comparative study on seven recent papers depending on the standard analytic measures.

Title: Simplified Roaming Pacts among Operators vis-ŕ-vis Improved Subscriber Identity Privacy in Global Mobility Network
Authors: Hiten Choudhury
Abstract: In a Global Mobility Network, every subscriber is identified by a unique identity. This identity is used for authentication, authorization and billing. Before extending any service to a subscriber, s/he has to be authenticated. Since authentication requires identity presentation, it precedes all other forms of security like confidentiality, integrity protection, etc. Thus, the subscriber has to present his/her identity through an insecure channel in plain text, before any service is extended to him/her. Ensuring identity privacy to the subscriber is therefore a challenging security issue in mobile networks. Numerous research works have been carried out to strengthen the subscriber's identity privacy in mobile networks. Early researches in this area were focused on protecting the subscriber’s identity from an eavesdropper over the radio link between the user equipment and the visited network. Recent research however has gone a step ahead, by making an attempt to enhance the subscriber’s privacy by protecting the subscribers' identity from even the visited network that may practically be forged or compromised. In this paper, a positive impact of this new development, in the form of simplified roaming pacts among the mobile operators, is highlighted.

Title: Review on Significance of Text Pre-processing Techniques in Sentiment Analysis and Opinion Mining
Authors: Kulpreet Kaur and Shruti Aggarwal
Abstract: Data Mining is a non-trivial process of analyzing large databases or data warehouses to extract knowledge or useful patterns. Sentiment analysis is an area in data mining that uses ‘Web’ as a data source. It is also known as Opinion Mining and is a very important and widely studied topic in Web content mining and Natural language processing. It is a process of extracting sentiments or emotions from a database of reviews or comments. It is generally seen as a classification task that groups the reviews according to their polarity but it can actually accomplish tasks such as summarization, spam content detection, product recommendation, buying behaviour recognition and objectionable content detection on social media also. Mostly data collected from web is in unstructured and noisy form so pre-processing of web content is a crucial step and increases the accuracy of classifier in sentiment analysis but it is often ignored. Keeping in mind the importance of this step, major pre-processing techniques are reviewed and various combinations are analyzed for their advantages and disadvantages. This paper presents an overview of sentiment analysis and different pre-processing techniques used in it.

Title: Design of Microstrip Antenna Array for RADAR Application : A Review
Authors: Kanchan Wagh and S.S.Shriramwar
Abstract: Phased Array Radar technology has seen great improvement since their inception in 50s. The development of microstrip antenna for phased array radar increasingly great importance. This paper reviews the research and development in this subject from inception till today. Conventional antennas antennas are large in size and they need to get installed properly because of their large size. Eli Brookner was the pioneer in the field of Phased Array Radar. He was working in the field of radar since the 50s. The research in the field of radar was greatly increased from World War II. Beam steering switching antennas were widely used and preferred. By controlling amplitude excitation of the elements in an antenna array, an efficient null broadening was achieved. People were preferring a slot into the design for higher bandwidth requirements. The slot microstrip antenna was used as a folded slot dipole. Defective Ground Structure had been extensively used by many authors for the improvement of bandwidth. DGS is an etched periodic or non periodic structure in ground plane. A new concept has been evolved named as a Complimentary Split Ring Resonator (CSRR). The two concentric open circular rings are etched on ground plane. Frequency Selective Surface (FSS) are the resonant structures having either stop band or pass band performance, due to which they are widely used as radomes and electromagnetic absorbers. Microstrip antennas are commonly used with an upper dielectric protective layer called as radome which provides mechanical protection and weatherproof operation. Electric parameter of antenna get affected if the dielectric constant of radome is not unity.

Authors: Deepanshu Vijay, Rita Mahajan and Deepak Bagai
Abstract: Current mode threshold logic is a popular CMOS based approach to implement logic functions. This paper presents the implementation of logic function using all current mode threshold logic based circuit. It shows logic function can be implemented using CMOS based current mode logic with less transistors. In this paper we are using all current mode circuits consist of two parts: the differential part and the sensor part. The number of transistors in the sensor part is constant and does not depend on the implemented function. The result shows that many functions can be implemented using these predefine circuit and hardware requirement is reduced compared to traditional CMOS based design.

Title: High Speed Multi-Rate Decimation Filter with Optimized Area for Efficient FPGA design
Authors: Nasir N. Hurrah and Shabir A. Parah
Abstract: In this paper aspeed and area efficient decimation filter is proposed for high performance FPGA implementation for wideband converters. The design is optimized for area and suited particularly for filters with high decimation factor. The filter offers a decimation factor of 128 having input from Sigma-Delta Modulator. For achieving high speed operation of Decimation filter We have employed efficient design procedures in the form of pipeline architectures, polyphase decomposition, retiming structures, Canonical Sign Digit encoders and resource sharing. These techniques have been used for designing the optimally selected multi stage filers like Non-Recursive Comb filters, Cascaded Integrated Comb Filters and Half Band Filters. Each filtering stage is placed before or after another filter while keeping all the speed, area and power consideration up to an efficient level. The filter offers reduced word-lengths effects thereby providing increased speed and reduced power consumption. From the results it is shown that a better power conservation is achieved along with minimum consumed area while achieving high speed performance in the form of less design complexity. Experimental results show that the proposed filter design can prove one of the best options for future design consideration of decimation filter for Sigma Delta Analog to Digital converters.
