Nonlinear autoregressive moving average-L2 model based adaptive control of nonlinear arm nerve simulator system

This paper considers the trouble of the usage of approximate strategies for realizing the neural controllers for nonlinear SISO systems. In this paper, we introduce the nonlinear autoregressive moving average (NARMA-L2) model which might be approximations to the NARMA model. The nonlinear autoregressive moving average (NARMA-L2) model is an precise illustration of the input–output behavior of finite-dimensional nonlinear discrete time dynamical systems in a neighborhood of the equilibrium state. However, it isn't always handy for purposes of neural networks due to its nonlinear dependence on the manipulate input. In this paper, nerves system based arm position sensor device is used to degree the precise arm function for nerve patients the use of the proposed systems. In this paper, neural network controller is designed with NARMA-L2 model, neural network controller is designed with NARMA-L2 model system identification based predictive controller and neural network controller is designed with NARMA-L2 model based model reference adaptive control system. Hence, quite regularly, approximate techniques are used for figuring out the neural controllers to conquer computational complexity. Comparison were made among the neural network controller with NARMA-L2 model, neural network controller with NARMA-L2 model system identification based predictive controller and neural network controller with NARMA-L2 model reference based adaptive control for the preferred input arm function (step, sine wave and random signals). The comparative simulation result shows the effectiveness of the system with a neural network controller with NARMA-L2 model based model reference adaptive control system.

Digital Preservation and Access of Natural Resources Documents

Digitization and preservation of natural resource documents were reviewed and the current status of digitization presented for a North American university. It is important to present the status of the digitation process for natural resources and to advocate for increased collections of digital material for ease of reference and exchange of information. Digital collections need to include both published documents and ancillary material for research projects and data for future use and interpretation. The methods in this paper can be applied to other natural resource collections increasing their use and distribution. The process of decision making for documents and their preservation and inclusion in ScholarWorks is presented as a part of the Forest Sciences Commons as a subset of the Life Sciences Commons of the Digital Commons Open Network launched and maintained by bepress. Digitization has increased the roles and skillsets needed for librarians and from libraries. This creates new challenges and opportunities for the library as publisher and as an advocate for open access. Digital curation melds together digitization and knowledge management and enhances community engagement. Digitization of collections are reviewed and natural resource documentation presented for faculty publications, Research Projects and Centers, eBooks, Journals, Galleries and electronic Theses and Dissertations (ETDs). Recommendations are made to increase the digital curation of the collection by encouraging community participation and use. Digital archives are important to natural resource professionals as society-ready natural resource graduates need to deal effectively with complex ecological, economic and social issues of current natural resources management. Natural resource research for the future needs to ensure that professionals have a greater breath of knowledge as they interpret and apply new knowledge, understanding, and technology to complex, transdisciplinary social and biological issues and challenges

A QoS-Aware Routing Protocol for Real-time Applications in Wireless Sensor Networks

The paper presents a quality of service aware routing protocol which provides low latency for high priority packets. Packets are differentiated based on their priority by applying queuing theory. Low priority packets are transferred through less energy paths. The sensor nodes interact with the pivot nodes which in turn communicate with the sink node. This protocol can be applied in monitoring context aware physical environments for critical applications.Comment: 10 pages. arXiv admin note: text overlap with arXiv:1001.5339 by other author

Comparison of Mixed H 2 H∞ with Regional Pole Placement Control and H 2 Optimal Control for the Design of Steam Condenser

This paper investigates the comparison between mixed H 2 /H∞ with regional pole placement control and H 2 optimal control for the design of steam condenser. The comparison have been made for a step change in the steam condenser pressure set point for a step change of 10 & 23 seconds using MATLAB/Simulink environment for the steam condenser with mixed H 2 /H∞ with regional pole placement controller, steam condenser with H 2 optimal controller and steam condenser without controller. The steam condenser with mixed H 2 /H∞ with regional pole placement controller presented excellent and superior dynamic performance in response to the two step changes and an improvement in settling time. The overall simulation results demonstrated that the steam condenser with mixed H 2 /H∞ with regional pole placement controller can be an efficient alternative to the steam condenser with H 2 optimal controller for the steam condenser

An Efficient Transport Protocol for delivery of Multimedia An Efficient Transport Protocol for delivery of Multimedia Content in Wireless Grids

A grid computing system is designed for solving complicated scientific and commercial problems effectively,whereas mobile computing is a traditional distributed system having computing capability with mobility and adopting wireless communications. Media and Entertainment fields can take advantage from both paradigms by applying its usage in gaming applications and multimedia data management. Multimedia data has to be stored and retrieved in an efficient and effective manner to put it in use. In this paper, we proposed an application layer protocol for delivery of multimedia data in wireless girds i.e. multimedia grid protocol (MMGP). To make streaming efficient a new video compression algorithm called dWave is designed and embedded in the proposed protocol. This protocol will provide faster, reliable access and render an imperceptible QoS in delivering multimedia in wireless grid environment and tackles the challenging issues such as i) intermittent connectivity, ii) device heterogeneity, iii) weak security and iv) device mobility.Comment: 20 pages, 15 figures, Peer Reviewed Journa

The legal implications of gas flaring on climate change in Nigeria

Global atmospheric concentration of substances that trap heat causing warming and change of climate is caused mostly by man’s activities- anthropogenic. Since efforts to curtail anthropogenic climate change commenced and countries came together to agree under the Kyoto Protocol to reduce carbon emissions, incidentally a larger percentage of the world was left out, constituting the developing countries, some of which eventually turn out to become leading carbon emitters, like Nigeria and others. Nigeria is a large carbon emitter through its oil exploration activities involving gas flaring. The country’s mainstay is its oil which predominantly dominates its revenue profile. The consequences of its gas flaring are enormous, which constitutes a threat to its environment and to the entire region. Keywords: Gas flaring, oil exploration, legislation, pollution, environment

Effects of Motivation on Test Performance of First Year Covenant University Students

This study examined the effect of motivation on test performance of first year Covenant University students, Ota, Ogun State. The study adopted pre-test, post-test experimental design. Data for the study were obtained from sixty (60) students with age range between 15 and 18 years (average age = 16.5 years). Participants were randomly assigned to three conditions using independent group design. The independent and dependent variables were motivation and test performance respectively. The two hypotheses were analysed using Mann- Whitney U test. The result shows a significant difference between the result of the unrewarded students in the control group and students rewarded with verbal praise in the experimental group (U = 61.000, N1 = 20, N2 = 20, p< 0.05, one-tailed). There was also a significant difference between the result of the students rewarded with primary reinforcers and the unrewarded students in the control group (U = 45.000, N1 = 20, N2 = 20, p< 0.05, one-tailed). This study justifies the importance of motivation on test performance. To improve students’ academic performance, teachers are encouraged to motivate their students. Key words: Teachers, motivation, test performance, Ot

Corporate Governance as a Tool for Curbing Bank Distress in Nigeria Deposit Money Bank: Empirical Evidence

The study objective is aimed at finding the relationship between corporate governance bank distress in deposit money banks. The research design adopted in this paper is the case study method, in other to have an intensive insight of the subject matter. Primary data was used specifically the survey technique.The method that was used in the presentation of data in this study is the Statistical Package for Social Sciences(SPSS) which contains all the necessary and important statistical technique for data analysis. For testing the hypothesis, correlation analysis which measures the degree of relationship between variables was used to analyze the result generated from the questionnaire. The evidence shows that corporate governance has no significant improvement on the prevention of bank distress but has significantly improved the performance of the Nigerian banking sector. We therefore recommend that banks should demonstrate strong internal policies to identify and manage conflict of interest and zero tolerance posture against cases of unsound corporate governance practices

Remoulding Welfare Britain: The Philosophy of the Big Society in Cameron’s Britain

Since the election of David Cameron as Conservative Party Leader there has been renewed interest in the functions and philosophies underpinning the responsibilities of the state. In 2008 David Cameron advanced the argument that Britain was ‘broken’. During the subsequent 2010 election campaign he put forward a remedy seeking to ‘fix’ Britain. David Cameron’s perception is that some social dynamics of our society are living without a comparable sense of social responsibility, seemingly devoid of any form of self control. Cameron’s narrative was in part enhanced by the several days of rioting in 2011. The subsequent rhetoric of the senior Coalition partner was given rocket boosters in selling this argument to the electorate, and that only the solutions offered by the Big Society could tackle this divide in Britain’s society
