In this paper, we consider experiential evidences in support of a set of object-oriented software metrics. In particular, we look at the object oriented design metrics of Chidamber and Kemerer, and their applicability in different application domains. Many of the early quality models have followed an approach, in which a set of factors that influence quality and relationships between different quality factors, are defined, with little scope of measurement. But the measurement plays an important role in every phase of software development process. The work, therefore, emphasizes on quantitative measurement of different quality attributes such as reusability, maintainability, testability, reliability and efficiency. With the widespread use of Object Oriented Technologies, CK metrics have proved to be very useful. So we have used CK metrics for measurement of these qualities attributes. The quality attributes are affected by values of CK metrics. We have derived linearly related equations from CK metrics to measure these quality attributes. Different concepts about software quality characteristics are reviewed and discussed in the Dissertation. We briefly describe the metrics, and present our empirical findings, arising from our analysis of systems taken from a number of different application domains. Our investigations have led us to conclude that a subset of the metrics can be of great value to software developers, maintainers and project managers. We have also taken an empirical study in Object Oriented language C++. © 2013 IEEE.

The Word "Biorhythm" is derived from the Greek word "Bios" which means life and "Rhythm" which means flowing with a regular movement. Biorhythm theory uses mostly scientific methods to chart the rhythms or cycles that affect the internal functioning of the body and of human behavior. This is particularly applicable to the physical, emotional and intellectual or mental abilities. Biorhythm theory states that, at the moment of birth three statistical cycles are initiated and these will recur consistently throughout life. This chapter proposes an investigation of the reasons for human error as a contributing factor in flying accidents. Physical factors such as man machine interactions involved in flying mistakes and a taxonomic approach to errors has been proposed in this chapter, in order to avoid accidents. This chapter presents a new methodology based on a probabilistic approach for biorhythmic analysis in an attempt to prevent aviation accidents. The methodology has been developed using a Gaussian distribution technique for evaluation of the aviation system reliability considering the biorhythmic effects on the pilot. Normal distributed data from the US air force were tested and analyzed. These were based on the performance ability of pilots and the peak demand of the performance using a Gaussian distribution approach. Validation of an aircraft accident due to biorhythm is explained in this chapter with consideration of the peak performance demand and differing standard deviations in the performance ability of each pilot. A new curve named the Incident - Duration Curve has been introduced. This is based on a biorhythmic analysis of Indian and US air force data. The area under normal distribution curve of the US air force data represents the successful performance ability zone of the Pilot. The accident zone is the area of operation during which the Performance Demand exceeds the Performance Ability of the particular aircraft pilot. Operation within the zone of the normal distribution curve is successful owing to ability and fitness of the particular pilot. Failure probabilities considering Peak Performance Demand and pilot's ability have been evaluated using a Gaussian distribution approach. A Safety Factor Concept is also given in this chapter. This has been done so as to include biorhythmic analysis in the attempt to avoid aviation accidents. A Stepped Incident-Duration Curve has been utilized in order to evaluate the particular pilot's reliability when using the system. The complete aviation system was evaluated by using Simpson's 1/3rd rule. © 2011 Springer-Verlag Berlin Heidelberg.

The reliable operation of offshore wind farms requires suitable real-time, automated and remote structural-health monitoring of the wind farm using wireless sensor networks (WSNs) for ensuring consistent power supply to the grid. This study presents a novel WSN packet-size reduction technique using flexible thresholds for real-time fault prediction in wind farms which is an extension to the authors work proposing application-specific network-lifetime enhancing tri-level clustering and routing protocol for increasing the network lifetime. The selection of flexible threshold utilises the degree of correlation between data samples collected at different times of the day. Using combination-summation and flow direction of received data, accurate fault prediction is achieved. The method is compared with the primitive mean method. The proposed method flexible threshold selection and fault prediction (FTSFP) provides a simple means for predicting real-time fault occurrences in the towers and helps in reducing the message size considerably, thereby increasing the network lifetime of the system nearly by ten times. The results confirm that FTSFP has better fault-prediction accuracy over the existing method. © The Institution of Engineering and Technology 2015.

In this paper,we explore the use of Dual tree Complex wavelet Transform which is nearly shift invariant and directionally selective in two and higher dimensions. The multidimensional dual tree CWT is a nonseparable and is based on computationally efficient, Separable filter bank (FB). This paper describes how the complex wavelet transform with directional properties is designed and use of it in image compression. When we take the dual tree complex wavelet transform then many wavelet coefficients are close to zero and have intra-subband dependency. We further evaluate the performance of SPIHT coding schema for coding of those coefficients. The result of proposed schema gives higher rate of compression and lover MSE compared to the schema based of DWT. Dual tree complex wavelet transform-SPIHT schema outperform DWT based schema at lower bit rates. © Springer India 2014.

Field experiments were conducted to study the effect of organic matrix based slow release fertilizers (SRFs) on plant growth, nitrate assimilation and seed yield of Brassica juncea L. cv. pusa bold. The agro-waste materials like cow dung, clay soil, neem leaves and rice bran were mixed together in 2:2:1:1 ratio and used as organic matrix for the immobilization of chemical fertilizer nutrients with commercial grade saresh (Acacia gum, 15% solution) as binder. Different fertilizer treatments were organic matrix based slow release fertilizers, SRF-I (542.0 kg ha -1); SRF-II (736.5 kg ha -1) and chemical fertilizer combinations, boron (3 kg ha -1)+sulphur (15 kg ha -1)+nitrogen (80 kg ha -1) and boron (3 kg ha -1) + sulphur (15 kg ha -1)+nitrogen (80 kg ha -1)+phosphorus (15 kg ha -1)+potassium (100 kg ha -1). Organic matrix based SRF-II released ammonium up to 50-d in wet soil under laboratory conditions which showed maximum retention of the nutrients. A very significant increase in plant growth, nitrate assimilation and seed yield was recorded in organic matrix based SRF-II applied plants. The maximum percent increase in biomass production was observed with organic matrix based SRF-II (increase of 65.8% in root fresh weight, 38.0% in root dry weight, 45.9% in leaf fresh weight plant-1 and 27.5 % in leaf dry weight plant -1 in 60-d old plants). It also increased the acquisition and assimilation of nitrate from the plant's rhizosphere which was evident by 45.6% increase in nitrate, 27.5% in nitrite and 11.7% in nitrate reductase activity (NRA) in leaves of 45-d old plants over control. The organic matrix based SRF-II significantly increased the seed yield by 28% in Indian mustard. Cost analysis revealed that this formulation is cost effective as it is based on agro waste materials. © 2011 Triveni Enterprises.

In this paper new wavelet bi-orthogonal filter coefficients for wavelet decomposition and reconstruction of image are introduced for better image compression, when the image is compressed by using these filter coefficient in DWT-SPIHT schema then it perform better than DWT-SPIHT schema with wavelet 9/7 filter and wavelet 5/3 filter. The compression result by using these filter coefficient show that the reconstructed image has higher PSNR and low MSE than wavelet 9/7 filter and wavelet 5/3 filter. © 2012 IEEE.

This paper proposes an efficient method for the design of two-channel, quadrature mirror filter (QMF) bank using polyphase components. The design problem is formulated to minimize an objective function, which is a linear combination of pass-band error and stop-band residual energy of the low-pass analysis filter of the filter bank. Unlike the other techniques which involves linear and non linear optimization, our formulation reduces the design equation to an eigenvector problem. An objective function that minimizes the stop-band energy and square error of the distortion transfer function uses the polyphase components and optimization is done using the power method. Simulation results of the algorithm shows the improved performance of the proposed method. Polyphase decomposition results dramatic computational efficiency and reduces number of iterations. © 2011 IEEE.

Cloud computing is a way of computing, via the Internet, that broadly shares computer resources instead of using software or storage on a local PC. Cloud computing is an outgrowth of the ease-of-access to remote computing sites provided by the Internet. Instead of installing a suite of software for each computer, we'd only have to load one application. That application would allow workers to log into a Web-based service which hosts all the programs the user would need for his or her job. Remote machines owned by another company would run everything from e-mail to word processing to complex data analysis programs. It's called cloud computing, and it could change the entire computer industry. In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user's side decrease. The only thing the user's computer needs to be able to run is the cloud computing systems interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest. © 2010 IEEE.
