Vibration control of a smart structure is investigated by means of PID as well as H-infinity control schemes. The smart structure consists with a cantilever plate of aluminum of size (160mm x160mm) and piezo-patches of size 20mm x 20mm. Sensors and actuators, which are square in shapes, are embedded to the parent structure. The active controller was designed to control first three modes of vibration of plate. The plate was discretised into square elements of identical size in order to optimize the different locations to sensors and actuators, which were assumed to be of the exact shape of the discretized plate elements. A comparison work has been obtained between these two controllers on the basis of data precipitated in the MatLab. The experimental results showed that proposed controllers (PID & H-infinity) can suppress the effect of external disturbances in the plate.

Shelter is amongst the three basic human needs but now-a-days, about two-third of the total Indian population does not have their own shelter. This two-third population belongs to the middle and lower income class. These people find it difficult to construct their houses at an affordable cost by using conventional construction technology. It is found in many cases that people serve their whole life constructing their own house, but fail. The mission and dream of these people can be achieved by appropriate use of cost effective and innovative construction technology. As a whole, the housing shortage of the country can be overcome within lesser funds, without compromising with the quality control and structural stability of the structure. Note: This technology is only applicable for single or two storied buildings and can be applied in most of the soil and climatic conditions.

One of the most important issues for power companies and users is to maintain the quality of power .Voltage sag, voltage swell and interruption comes under short term voltage variations. In order to mitigate these variations, a custom power device called dynamic voltage restorer (DVR) is used.Its basic function is to inject the voltage difference (difference between pre-sag & sag voltage ) to the power line in such a phase so that it can maintain the pre-sag or pre-swell voltage condition in the load side with in few milliseconds. In this paper, a PV based dynamic voltage restorer (DVR) has been proposed to mitigate voltage sag, swell and interruptions on a low voltage residential distribution system. The PV based DVR can recover sags up to 0.1 pu, swells up to 1.9pu. Otherwise, it work as an uninterruptable power supply (UPS) when the utility grid fails to supply. This PV based DVR comprises of PV system with MPPT controller, boost converter, PWM voltage source inverter, series injection transformer & semiconductor switch. Modeling and simulation has been done in MATLAB software. The simulation result shows that proposed DVR works effectively to mitigate voltage sag, swell and interruptions.

The massive amount of data required for images is a primary reason for the development of many sub areas within the field of computer imaging such as image segmentation and compression. Whatever may be the way of transmission, the data tends to get noisy and thereby the further processing does not lead to good results. Hence, it is very essential to keep the data close to originality. In order to achieve this in terms of the concerned work, wavelet transforms have been applied: Discrete wavelet transform and EEMD. In this thesis, a new technique which is combination of Enhanced Empirical Mode Decomposition (EEMD), has been presented along with the standard wavelet thresholding techniques like hard thresholding to denoise the image.

In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper. In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives.

In Mobile Cloud Computing (MCC), load balancing is essential to distribute the local workload evenly across all the nodes either statically or dynamically. A high level of user satisfaction and resource utilization ratio can be achieved by ensuring an efficient and fair allocation of all computing resources. In the absence of proper load balancing strategy/technique the growth of MCC will never go as per predictions. The appropriate load balancing helps in minimizing resource consumption, implementing fail-over, enabling scalability, avoiding bottlenecks. We introduce the concept of "skewness" to measure the unevent utilization of a server. By minimizing skewness, we can improve the overall utilization of servers in the face of multi-dimensional resource constraints. We design a load prediction algorithm that can capture the future resource usages of applications accurately without looking inside the VMs. The algorithm can capture the rising trend of resource usage patterns and help reduce the placement churn significantly.

People when they speak, interact and write convey emotions. The life is an emotion. Emotions play a key role in any kind of decision in affective, social or business area. The emotions are manifested in verbal, facial expressions but also in written texts. Nowadays, with the growth of internet and social media like facebook twitter , many humans interact, in textual manner with each other in large , and exchange ideas, opinions in the web channel or web communities. Emotions in text are very important if we consider that textual interface with the computer is one of the most used. Emotions are treated largely in affective computing that focuses on improving the interaction between user and computer. People express emotions as part of everyday communication. Emotions can be judged by a combination of cues such as facial expressions, prosodies, gestures, and actions. Emotions are also articulated by written texts. Inspired by works in sentiment analysis, this paper explores approaches to automatic detection of emotions in text. I draw from emotion theories in the fields of psychology and linguistics, and use natural language processing and machine learning techniques for automatic emotion detection. In this paper, I describe studies and experiments in manual and automatic recognition of expressions of the six basic emotions (Ekman, 1992) – happiness, sadness, anger, disgust, surprise, and fear – in text form.

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. The principles of OFDM modulation have been around since 1960s. However, recently, the attention toward OFDM has grown dramatically in the field of wireless and wired communication systems. A set of orthogonal sub-carriers together forms an OFDM symbol. To avoid ISI due to multi-path, successive OFDM symbols are separated by guard band. This makes the OFDM system resistant to multi-path effects. The main advantage of this transmission technique is their robustness to channel fading in wireless communication environment. This is reflected by the adoption of this technique in applications such as digital audio/video broadcast (DAB/DVB), wireless LAN (802.11a and HiperLAN2), broadband wireless (802.16) and xDSL. The main focus of this paper is to design IFFT and FFT blocks which are used in transmitter and receiver of the blocks diagram of OFDM system. The methodology used is the IFFT/FFT(DIT) with radix-2 butterfly algorithm. The design unit also consists of modulation and demodulation for mapping technique.

Local authorities constitute worldwide the main providers of waste management services. Waste collection and transport is responsible for a large fraction of the total waste management costs, EU policy requires that waste is treated to recover materials and energy prior to disposal and this increased level of service needs to be provided at the minimum possible cost, as the public will not be able to bear large increases in its waste charges. Municipalities are therefore under increased pressure to optimize their services, both in terms of quality and costs. Geographic Information System (GIS) technology provides an advanced modeling framework for decision makers in order to analyze and simulate various spatial problems, including various waste management aspects. In this study a methodology for the optimization of the waste collection and transport system, is developed. GIS technology is used to improve the efficiency of waste collection and transportation of waste collection bins, by locating the exciting routes and time.

Watermark refers to digital data embedded in cover data with an intent of copyright protection or proof of ownership. In case of image watermarking, the robustness of watermarks to geometric attacks is considered to be the most challenging design requirements for watermarks. Geometric attacks like Rotation, Scaling and Translation (RST attacks) can desynchronize the location of the watermark and hence cause incorrect watermark detection. In this paper, a new color image watermarking scheme for copyright protection is proposed. This scheme utilizes the features of the image which are invariant under rotation, scaling and translation of images. Moments and functions of moments have been extensively employed as invariant global features of images in pattern recognition. The proposed work utilizes Hu's invariant moments for watermark generation. The same can be detected and extracted at the detector to serve for copyright protection. The moments are invariant against image rotation, scaling and translation. Thus, the proposed watermarking scheme is robust against RST attack. Original unmarked image is not required at the detector for watermark detection and extraction. Thus, the proposed scheme provides a way for blind watermarking. The simulation is done using MATLAB and results are compared with existing techniques of invariant feature based watermarking schemes. Comparison of the results are presented which shows a considerable improvement in Peak Signal to Noise Ratio.

Digital Watermarking refers to hiding digital data in digital content with intent to enable copyright protection and illegal distribution. Digital audio watermarking deals with embedding digital information in an imperceptible manner in the host audio signal. Audio watermarking involves much more complex techniques to embed watermark in view of superiority of Human Auditory System (HAS) over Human Visual System (HVS). Spread Spectrum watermarking embeds the watermark in frequency domain, thereby providing a much more robust and invisible watermarking scheme as compared to time domain watermarking, which is comparatively fragile. It turns out that digital watermark embedding in audio signals in any domain results in audible disturbances in the original audio signal. To compensate for these unwanted disturbances in audio files, audio watermarking techniques are to be augmented with Frequency Masking (FM) techniques. It turns out that PAFM creates an imbalance in the number of positive and negative chips that are used to modulate the watermark, and consequently, it introduces error in correlation test. This paper proposes a robust audio watermarking technique based on the patchwork algorithm. Peak Signal to Noise Ratio (PSNR) is evaluated as a function of embedding capacity and robustness. PAFM is analyzed as a function of the threshold limit for embedding of watermark bits. The proposed method provides an optimized way to embed watermark using spread spectrum technique, with a detector of minimal complexity and maximum achievable efficiency. MABLAB is used to simulate the technique and results are derived. PSNR is used as a quality metric for evaluation of the results.

The rapid advancement and extensive growth in communication technology is creating a critical need to develop novel methods and techniques to protect copyright, ownership, authentication and content integrity of digital media. An efficient solution to this kind of problem is digital watermarking of multimedia. A watermark refers to a visible or invisible digital data to be embedded in a cover data so as to provide copyright protection at time when need arises. Numerous watermarking and steganographic methods have been presented in the literature and several watermarking software packages have been developed in past decades. Still robustness and security of watermark against a variety of attacks is one of the most important issues to be solved. In this paper, grayscale 8 bit images are considered for watermark embedding. However, techniques are proposed so that the method is directly applicable for watermarking of color images. Discrete wavelet transform is used to provide robustness and Noise Value Function (NVF) and Arnold Scrambling is used to provide security. Watermark generation is done using LL band of NVF function of original image. The watermark is then subjected to Arnold Transform to introduce randomness, thus enhancing security and improving PSNR. Embedding is done in low frequency LL band of original image. Inverse Discrete wavelet Transform is then computed to obtain the watermarked image. The results are evaluated by applying number of attacks on the watermarked image.
