In this paper, a novel circular fractal antenna is analyzed in details. The antenna is mounted on a FR4 dielectric substrate having a dimension of 48 x 60 mm2. A 50 ohm microstrip feed line is used to excite the antenna. In order to realize wide bandwidth, a slot is etched in the ground. For each and every iteration, the slot dimension is adjusted in order to achieve desired results. In the later section of the paper, a U shaped slot is inserted in the microstrip feed line which leads to an effective band rejection of 1.72 GHz (5.869 GHz -- 4.149 GHz). The antenna shows stable radiation patterns and good return loss characteristics. All the analysis is done in HFSS 2013.

Node localization is one of the main challenges in Wireless Sensor Networks (WSNs). In all sensor network applications, it is important to know the origin of collected data and reported events. This paper proposes a bio-inspired method for solving the WSN localization problem which is formulated as a non linear optimization problem. An Artificial immune inspired, population based optimization algorithm called Clonal Selection Algorithm (CSA) is used for locating nodes in a sensor network scenario. The performance of CSA based localization scheme is evaluated through simulations and results are compared with Particle Swarm Optimizer (PSO) based localization method. Also, evaluation is performed using data collected from a real WSn testbed.

On-line handwriting recognition means recognizing the user's handwriting as the user is writing the character/stroke, i.e. the recognition is concurrent to the writing process. This paper describes a Multilingual Online handwriting recognition system in Android using SFAM Artificial Neural Network Technique. The app allows the user to select any of the target languages supported. The handwriting sequences are collected by the digitization of the pen/stylus movements as an array of x, y coordinates which is called a stroke. The structural and directional information are extracted from each character/stroke. The extracted features as a feature vector are passed as input to a SFAM artificial neural network (ANN) classifier. The SFAM classifier then performs a comparison of the input data with the trained data and finds the nearest prototype from the database that 'resonates' with the input pattern. The labels/recognized characters are assigned their corresponding Unicode code points and displayed using appropriate fonts.

National Transportation Communication for Intelligent Transportation System Protocol (NTCIP) is a family of open standards, defining common communications protocols and data definitions for transmitting data and messages between computer systems used in Intelligent Transportation Systems (ITS). The Intelligent Transportation Systems make use of Information Technology, Computers, Telecommunication and Electronics (ICTE) in the effort of improving safety and mobility of automobiles and road users. In this effort it is likely that the various devices and gadgets used in ITS communicate each other. As of now many ITS solutions use proprietary protocol for communication that restricts interoperability and interchangeability while sharing a common platform. NTCIP provides the benefits of device interoperability and interchangeability, bridging the gap. In ITS, the Adaptive Traffic Control System (ATCS) is widely accepted in the present day for road traffic control and realtime signal coordination. The ATCS receives traffic information from all traffic junctions in a road traffic network in a timely manner. This information is processed centrally by the ATCS and signal timings at the traffic junctions are updated in realtime for minimum stops and delays to improve the travel time. There are many vendors manufacturing ATCS and traffic controllers with their proprietary protocol. This leads to the lack of interoperability between the ATCS and the traffic controllers restricting the expandability and customer choice. This problem can be overcome by adopting the concept of NTCIP in the communication process. This paper discusses how the traffic controller is made NTCIP compliant by adding the SNMP Agent functionality into it and how the communication is carried out in the form of NTCIP standards in spite of its proprietary terminology.

Rectangular slot cut compact shorted 90° Sectoral Microstrip Antenna is proposed. An analysis to investigate the effect of rectangular slot which yields broader bandwidth is presented. The slot does not introduce any new mode but it reduces the resonance frequency of second order TM1/4,1 mode of the shorted patch. Due to its coupling with fundamental shorted TM1/4,0 mode, yields bandwidth of more than 500 MHz (>50%). Due to shorted patch, radiation pattern show higher cross polar levels with antenna gain of more than 3 dBi over the bandwidth.

This paper proposes to use speech commands for controlling a Micro Air Vehicle (MAV). The control commands for MAV are generated and transmitted through the Ground Control Station (GCS). Setting of values using keyboard and mouse can become cumbersome at the MAV mission site and therefore, speech is an effective alternative. In This paper open source Mission Planner GCS is integrated with the speech based control feature. The coding is done of Visual Studio using C# language.

A MANET consist of a collection of wireless mobile nodes in which packets are transmitted from one to another node via intermediate nodes within range. To find an efficient routing protocol, which is used to transmit data from source to destination across whole network, is a major issue in networking research. MANETs are flexibly distributed that can change their locations and are self-configurable. So they are highly appealing for a lot critical applications, like disaster relief, deep space communication, battlefield communication, etc. This paper presents various broadcasting techniques used in MANETs on the basis of parameters such as end-to-end delay, MAC retransmission rate, data transmission energy, etc. As these parameters are not yet close to acheive optimal peformance, a new solution is suggested here for better performance.

Social media has become very popular communication tool among internet users in the recent years. A large unstructured data is available for analysis on the social web. The data available on these sites have redundancies as users are free to enter the data according to their knowledge and interest. This data needs to be normalized before doing any analysis due to the presence of various redundancies in it. In this paper, LinkedIn data is extracted by using LinkedIn API and normalized by removing redundancies. Further, data is also normalized according to locations of LinkedIn connections using geo coordinates provided by Microsoft Bing. Then, clustering of this normalized data set is done according to job title, company names and geographic locations using Greedy, Hierarchical and K-Means clustering algorithms and clusters are visualized to have a better insight into them.

Conventional radar altimeter systems such as Pulsed or Frequency modulated continuous wave (FM CW) have limitations on measurable range and security. In this paper, we propose a Direct sequence spread spectrum (DSSS) based radar altimeter that offers good resolution and low probability of intercept. We carried out MATLAB simulations of the system and verified the results with a scaled down prototype model. Various system performance measures including Bit error rate (BER) were computed and compared with the theoretical results.
