In this paper, a new modeling approach is proposed by hybriding the features of expectation-maximization algorithm(GMM) and fuzzy c-means algorithm(FCM). Based on the analysis over conventional GMM technique, we suggested a new speaker identification system by fusing GMM (optimized using EM algorithm) and FCM, to improve the identification rate further in multilingual speaker identification system. The proposed technique and GMM technique was evaluated in mono and multilingual environments. Experiments were done also by varying the initial code books for generating speaker model. The experimental result shows improvements on a combined FGMM system, which employs fusion for the multilingual context with varying initial code books gives an improvement of minimum 2.98% than existing GMM approach. MFCC technique is used for extracting the features. The algorithms were compared using TIMIT database of 54 speakers speaking 3 languages like English, Hindi and Tamil.

In this paper analysis of emotion recognition from Marathi speech signals by exploring several patterns for feature extraction techniques and classifiers to classify speech utterance according to their emotion contains. In this paper several method are extracting feature from speech signal to estimation of energy, intensity and pitch contour using Mel Frequency Cepstral Coefficient (MFCC). These feature parameters are extracted from Marathi speech Signals depend on speaker, spoken word as well as emotion. Gaussian mixture Models (GMM) is used to develop Emotion classification model. Each subject/Speaker has spoken 7 Marathi words with 6 different emotions that is 7 Marathi words are Aathawan, Aayusha, Chamakdar, Iishara, Manav, Namaskar, Uupay and 6 emotions are Angry, Happy, Sad, Fear, Neutral/Normal, and Surprise. This system is used for emotion recognition in Marathi Spoken Words by applied feature extraction techniques as MFCC and classification techniques as GMM. We got 83.33 % average accuracy rate and 16.67% average confusion rate of our system. For Male we got average accuracy rate is 85% and for female 81.66 %. This is the overall accuracy rate of our Emotion Recognition for Marathi Spoken Words (ERFMSW) system.

Wireless communication devices and techniques are proliferating, improving and expanding every day. The development of such device must meet specific requirements: small size, light weight, low cost, and attractive appearance. There are many techniques to improve the characteristics and performance of antennas. A dense dielectric patch in a circular shape for the antenna is proposed here for reduced size copy of the whole. The beneficial give useful applications in cellular telephone and microwave communications. This paper presents the design and simulation of miniaturized single-band dense dielectric patch antenna for wireless applications.

This paper devotes to the channel estimation of a rapidly time varying environment for TD-HSPA+ technology. Based on the QR factorization of the midamble matrix, a modified channel estimator is proposed. To validate the method, several simulated cases with existing B. Steiner, Least squares (LS) and Minimum mean square error (MMSE) methods are considered. The simulation results demonstrate that the modified factorization method is more efficient, numerically stable and take less runtime than the conventional methods.

In Wireless era, Cross-layer designing of transmission power assignment and power control is the critical issues in emerging wireless technology. Intelligent transmission power selection algorithm depends on the notion of Transmission Power (TXPOWER), energy, Received Signal Strength Indication (RSSI) and the distance. The decentralized network without load balancing leads to network partitioning, route reliability, link failure and retransmission occurs. This power control Cross-layer design used for communicating information among the intermediate layers. LOADPOWR CONTROL Transmission power assignment algorithm in wireless networks leads to the network more efficient by using PWmin and PWmax power control technique. Euclidean distance calculates appropriate distance between sender and receiver in the network. Path loss model used to calculate difference between transmission power and received power for the amount of mobile nodes present in the LOADPOWER network. The key concept is to improve the network throughput, delay, distance, saves energy by sending all the packets with optimal transmit power according to the network load. Simulation was done in NS-2 simulator.

Images captured using consumer grade cameras are missing viable information of image which is depth. This also makes the image to be considered as a two dimensional image. The real life activities like recognition of objects by measuring the distance between objects become very complex and sometimes impossible. Stereo vision imaging, 3-D modeling techniques help to minimize these shortcomings. In this paper we have analyzed various novel works which used the depth information gathered from RGB-D cameras. Microsoft Kinect, a low cost RGB-D sensor has proved to be the most effective of its kind. This paper can provide a clear idea about the extensive research using these sensors that have been going on in the field of augmented Human computer interaction. The exceptional features of these depth sensors can be used to develop more sophisticated applications in the field of computer vision in near future.

For using in multiple transmits antennas systems, a number of Quasi-Orthogonal Space-Time Block Codes (QOSTBC) has been proposed. Based on circulant matrix, in this paper, we propose a novel method of extending any QOSTBC constructed for 8 transmit antennas to a closed-loop scheme. We prove that the proposed scheme can improve its transmit diversity with one bit feedback, with the aid of multiplying the entries of QOSTBC code words by the appropriate phase factors which depend on the channel information. The optimal constellation rotated schemes as well as performances of the proposed scenario 8 transmit antennas QOSTBC are analyzed. The simulation results suggest that there is a significant Eb/No advantage in the proposed scheme which is able to be designed easily.

Local binary pattern (LBP) is a nonparametric descriptor, which efficiently summarizes the local structures of images and has been very successful in image retrieval applications. In this paper, we propose a texture image retrieval technique which uses discontinuity binary pattern (DBP) along with the LBP. The DBP is formed by thresholding the absolute difference between the center pixel and its neighbors. This technique is applied to a database of 1180 sub-images from the twenty different classes of vistex database. Result shows that the proposed technique achieves good retrieval rate.

Dynamic topology changes are one of the characteristics of Mobile Ad hoc Networks (MANETs) where nodes move very frequently. Among ad-hoc routing protocols, Geographic routing protocols have drawn a lot of attentions in recent years due to its forwarding decision based only on local topology. Periodic broadcasting of beacon packets is a widely used method to maintain neighbor locations; but it is not impressive with respect to both routing performance and location update cost due to its periodic nature. Load unbalance is another issue which hampers the routing performance. Existing well known geographic protocol, Greedy Perimeter Stateless Routing (GPSR) is modified as LB-DB-GPSR(Load Balanced-Dynamic Beaconing GPSR), to adapt beaconing with respect to node mobility and traffic patterns in the network as well as to achieve a better Load balancing in the network. The simulation results show that the proposed protocol can significantly improve the routing performance in terms of packet delivery ratio, end to end delay and congestion control.

Binary 128 arithmetic finds a hard in floating point application of Quadruple Precision. The major component of 128 bit Fused Multiply Add (FMA) unit with multimode operations are Alignment Shifter, Normalization shifter, Dual Adder by CLA. The main contribution of this paper is to reduce the latency. The technical challenges in existing FMA architectures are latency and higher precision. The precision gets affected by the repeated occurrence of fractional part. In order to reduce the latency the dual adder is designed by using compound Adder and the latency of overall architecture gets reduced up to 30-40%. In this paper the total delay of dual adder designed using compound adder is found to be 5.776 ns. Simultaneously to get higher precision we design namely Alignment Shifter and Normalization Shifter in the FMA unit by using Barrel Shifter as this Alignment Shifter and Normalization Shifter will have less precision, but since replacement of these blocks by Barrel Shifter will result into higher precision.
