Abstract: This paper describes an investigation into the potential for different mobile application on home automation systems. It considers problems with their implementation, discusses possible solutions through various Mobile application platform and different network technologies and indicates how to optimize the use of such systems. The home is an eternal, heterogeneous, distributed computing environment which certainly requires a careful study before developing any suitable Home Automation System (HAS) that will accomplish its requirements. Now a days, mobile applications made were targeted to a particular Operating System only which restricted there usability. With the limitations of above in mind there is a need of a universal mobile application development platform.

In this paper we are going to compare the results for each type of compression technique. An extensive experimentation has been been carried out to arrive at the conclusion.

In this paper we suggest a method how to compress an digital image using various types of Discrete Cosine transform.

Abstract: Modified H-shaped array antennas are proposed to achieve high gain and good impedance matching for WiMAXapplications. Here a 3*2 H-shaped microstrip array antenna is designed. To reduce the return loss and for good impedance matching, the 50 ohm impedance transformer is used. By using H-shaped slot antenna, an air bridge can be avoided in design as well as the complexity of design can be reduced .The 180 degree phase shifters are organised in H-shaped antenna. It gives 7.77 dB gain and 11.97 dB directivity. The return loss of 16 dB and 24 dB can be achieved at 3.3 GHz and 3.7 GHz operating frequencies which are WiMAX frequencies. Index Terms:Modified H-shaped antenna, WiMAX, 50 ohm impedance transformer, 180 deg phase shifter.

Abstract: The design of radio frequency (RF) energy harvesting by using circular planar spiral inductor antenna arrays is proposed. The proposed antenna is a 2x1 circular spiral inductor. The size, return loss and radiation patterns were studied. It is expected that the proposed method is capable of harvesting RF electromagnetic energy more efficiently compared to when using single element spiral antenna. Both circular spiral inductors are fabricated on Roger 4003 substrates. Simulation results show that 5.14dBi gain for antenna array and 3.22dBi gain for single antenna can be achieved at frequency 527MHz. The gain has increased about 37.3% on the antenna array. Besides, practical results show that circular spiral inductor antenna array harvested more energy than a single element antenna. Therefore, the results obtained are a very attractive alternative design solution for energy harvesting system in the future. The array method of the circular spiral inductor antenna is successfully confirmed.

Abstract: Vehicular Adhoc Network (VANET) is one of the emerging and promising technologies of our near future which provides Network on Wheels (NOW). It provides safety and other applications to the drivers as well as passengers. It has become a key component of the Intelligent Transport System (ITS). VANET is the special type of MANET (Mobile Ad Hoc Networks) where the mobile nodes are vehicles that move on roads at very high speed following traffic rules; they provide communication between vehicle and vehicle (V2V) and Vehicle and Road side infrastructural unit (V2I).An attempt has been made earlier to create a new cluster model for efficient communication among the VANET nodes.In this paper a new clustering model has been created along with security algorithms so that the communication among the VANET nodes can be made in more efficient manner.

Abstract: In this paper we try to design and implement the logic of a Fuzzy Multiplexer (fMUX) system. A design of Fuzzy Multiplexer is presented and its generalization to classical logic has been shown with simulations. In fuzzy modelling, a fuzzy multiplexer fMUX acts as a fuzzy switch to select one of the fuzzy inputs. Selection of the inputs is determined by the value of candidate inputs termed as "Select Inputs". These fMUX's could be used as generic building modules in fuzzy systems. All simulations were done using MultiSim 11.0 .

Abstract: High Peak to Average Power Ratio (PAPR) is still a most important challenge in Orthogonal Frequency Division Multiplexing (OFDM) system. This paper proposes a modified Partial Transmit Sequence (PTS) technique which acquires its phase weighting factors from the Paley-I type Hadamard matrices with an objective to reduce the high PAPR in OFDM systems. The proposed technique achieves better PAPR reduction than traditional PTS-OFDM and it also obviate the need for exhaustive search for the viable phase weighting factors in PTS-OFDM, thereby reducing the computational overhead and also avoids the unwanted data rate loss.

Abstract: In this paper, we investigate the optimum received power for spectral amplitude coding optical code division multiple access (SAC-OCDMA) at different transmission distances using modified-AND subtraction detection technique and single photodiode (SPD) detection technique. We also investigate the effect of avalanche photodiode (APD) gain on the received power. Simulation results show that: 1) the received power decreases while the bit error rate (BER) increases with the transmission distance, and 2) both the received power and the BER increase with the APD gain for the same transmission distance.

Abstract: This paper is mainly aimed at developing an advanced communication aid for the people having severe speech impairment. This method gives rise to a new form of communication aid which recognizes the disordered speech of the user and builds messages which are converted into synthetic speech. While employing this method, the recognition perplexity can be increased. The selected message building technique traded-off various factors including speed of message construction and range of available message outputs. The trial high lightened some issues which limit the performance and usability of device when applied in real usage situations, with mean recognition accuracy of 67% in these circumstances. A field trial by individuals with moderate to severe dysarthia and confined that they can make use of the device to produce intelligible speech output from disordered speech input.

Abstract: spatial clustering method can be used for the analysis of satellite image to get the meaningful information with the help of fuzzy local information c-means algorithm using image segmentation technique. In previous clustering based image segmentation method may lose the important image details due to the noise present in the satellite image. The effects of noise are avoided by the spatial relationship among pixels, but it often generates boundary zones for the mix of pixel around the edges .To overcome these problem (FELICM) reduces the edge degradation by introducing the weights of pixel within the local neighboring windows.

Abstract:Adaptive streaming over Hyper-Text Transport protocol (HTTP) is the new trend in video delivery on the Internet and is expected to be supported by consumer electronic devices such as Blu-ray players and DVRs. Proprietary solutions have been around for a couple of years and standardization efforts are entering the final stage. Adaptive bit rate streaming is a technique used in streaming multimedia over computer networks. While in the past most video streaming technologies utilized streaming protocols such RTP with RTSP, today's adaptive streaming technologies are almost exclusively based on HTTP[1]and designed to work efficiently over large distributed HTTP networks such as the Internet. Experiments confirm that our algorithm outperforms popular segmentation techniques and saves10% of bandwidth on average for the same objective quality levels. This saving is significant given the volume of traffic that video delivery generates every day on the Internet.1

Abstract: In reconfigurable system, the size of bitstream and memory is reduced using bitstream compression. By reducing the reconfiguration time, the system can improve the communication bandwidth. Existing system shows that, at the cost of compression efficiency effective compression is achieved with slow or fast decompression rate. To improve both compression and decompression efficiencies, this paper proposes a new technique i.e., decode aware compression technique. Different approaches for the proposed system are i) A large set of matching pattern is created by using effective bitmask selection technique. ii) Using the bitmask and dictionary selection technique, a bitmask based compression is achieved because of which there is an efficient reduction in memory requirement. iii) Repetative patterns are generated by grouping bitmask based compression and run length encoding. Finally, using decompression engine the original bitstream can be generated.

Title	:	Analysis of E- Plane Radiation Patterns of a Simulated Scalar Feed Horn Antenna
Country	:	India
Authors	:	Dr. Stephen Rodrigues
	:	10.9790/2834-09239296

Abstract: Simulated scalar feed horn antennas are found to be exhibiting identical radiation characteristics of metallic corrugated feed horn antennas of same dimensions. Hence, in this paper, the E-plane radiation characteristics of a simulated scalar feed horn antenna is analysed theoretically by extending the theory of metallic corrugated horn antennas. The theoretical E-plane radiation patterns at different frequencies in X-band are compared with that of experimentally obtained E-plane radiation patterns. Even though the nulls of of the radiation patterns are not fully realised by the theory, the main beam characteristics are well explained. Losses that may occur in the dielectric substrate of the E-plane walls are not considered in the theoretical explanation. This may be the reason for slight discrepancies observed in the experimental and theoretical 3-dB and 10 dB beam widths.

Abstract: Mobile Ad Hoc network is a self-organizing infrastructure less network where the nodes are responsible for routing the packets. MANET has dynamic topology which allows nodes to join and leave the network at any time. This paper proposes a channel adaptive routing protocol which extends AOMDV routing protocol to accommodate channel fading. The proposed Channel Aware AOMDV protocol uses channel average nonfading duration to select stable links for route discovery. The main objective of this paper is to demonstrate approximation capability of artificial neural network. Feed forward network architecture with back propagation algorithm is used. Depending upon the size of database number of hidden layers and number of neurons in hidden layer are decided. Number of neurons in hidden layer is varied and effect on percentage deviation in the output parameter is observed. Depending upon nature of input and output parameters synthesis and analysis artificial neural network (ANN) models are trained.

Abstract: In recent years Evolutionary computation has its growth to extent. Synthesis of non-uniform linear antenna arrays is one of the most important electromagnetic optimization problems of the current interest. In this paper, the design of non-uniform linear antenna arrays with optimum side lobe level reduction is investigated. Two global evolutionary optimization methods are Particle Swarm Optimization algorithm(PSO) and Differential Evolution algorithm(DE ) are used to determine an optimum set of weights and positions that provide a radiation pattern with optimum side lobe level having uniform progressive phase between the elements. Simulation results show considerable enhancements in array performances using the global optimizers. The paper finally illustrates a comparative evaluation of the two proposed algorithms regarding their applicability as numerical optimization techniques.
Keywords: Linear Antenna arrays, Side lobe level (SLL), Differential Evolution (DE), Particle Swarm Optimization algorithm (PSO).

Abstract: To retrieve the information from huge amount of data and finding what kind of data to be mined is becoming progressively computerized. On the other hand selecting what data to gather requires human association or practice, generally delivered by field expert. This system describe that for prediction of some behavioral outcomes, non-field experts can jointly formulate structures and then provide values. Existing system not give the accurate behavioral model, this achieved in system by constructing a web site in which peoples respond to questions and pose new questions to others. This results in a dynamically-growing online survey. There are two different approaches for the system in which first can predict users monthly electricity consumption; the other predict users body mass index.
