A New Feature Extraction Method for Underwater Targets

in the complex underwater environment, underwater images are taken by special underwater CCD camera and its S/N is low and the edge is fuzzy. For the four types of characteristic underwater targets, the novel moments called relative boundary moments are proposed, and the affine invariants of discrete moments are constructed. With scale, translating and rotating invariance, the moments can be used as the descriptors of the samples. Experimental results show that compared with the traditional regional moments, the new moment invariants not only can reduce the calculation in data processing to a large extent, but also improve the robustness and timeliness for engineering applications. When applying to the practical engineering, that is particularly approval for AUV to complete a certain mission.

Using the bees algorithm to train neural networks for wood defect identification

This paper presents the Bees Algorithm (BA) and its application to the training of a multi-layer perceptron neural network. The neural network was used for identifying defects in wood veneer sheets. The bees algorithm is a novel population-based optimisation algorithm that mimics the natural foraging behaviour of swarms of bees. In its basic version, the algorithm performs a combination of neighbourhood search and global search. Following a brief description of the algorithm, the wood defect identification problem and the neural network used, the paper discusses the results obtained for four different cases: multi-layer perceptrons trained with the conventional back propagation algorithm and the bees algorithm using two different sets of data.
Physics-Based SPICE Model of a-InGaZnO Thin-Film Transistor Using Verilog-A

In this work, we report the physics-based SPICE model of amorphous oxide semiconductor (AOS) thin-film transistors (TFTs) and demonstrate the SPICE simulation of amorphous InGaZnO (a- IGZO) TFT inverter by using Verilog-A. As key physical parameter, subgap density-of-states (DOS) is extracted and used for calculating the electric potential, carrier density, and mobility along the depth direction of active thin-film. It is confirmed that the proposed DOS-based SPICE model can successfully reproduce the voltage transfer characteristic of a-IGZO inverter as well as the measured I-V characteristics of a-IGZO TFTs within the average error of 6% at VDD=20 V.
Self-Care Skills between Institutionalised and Home Dwelling Older Adults: A Preliminary Study

Self-care is defined as activities performed by individuals, families, and communities to enhance their health, prevent diseases, limit illnesses, and restore health. Previous research has mainly focused on self-care skills of older adults in either institution or residential homes separately but limited studies have compared between both these settings. This study aimed to compare the self-care skills between institutionalised and home dwelling older adults at selected area in Malaysia. A total of 43 participants aged 60 years old and above were recruited in our study; (23 participants were home-dwelled older adults and 19 participants were recruited from institutionalised older adults located in Kuala Lumpur). The Malay Version of Performance Assessment of Self-Care Skills ( M-PASS - HOME ) 4.0 was used focusing on four main subtests of self-skills; oral hygiene, trimming toenails, house mobility and shower mobility. The differences in self-care skills between institutionalised and home dwelling older adults are statistically significant (p<0.01) in the aspects of independency for all self-care activities. The results of this study revealed that home dwelling older adults group are more independent in self-care activities of oral hygiene, trimming toenails, house mobility and shower mobility compared to institutionalised group.
Classification and relationships between risks that affect lean production implementation

Purpose – The purpose of this paper is twofold: to classify the risks that affect the lean production implementation (LPI) process, and to demonstrate how that classification can help to identify the relationships between the risks. Design/methodology/approach – Initially, a survey was conducted to identify the probability and impact of 14 risks in LPI, which had been identified based on a literature review. The sample comprised 57 respondents, from companies in the south of Brazil. An exploratory factor analysis was carried out to analyze the results of the survey, allowing the identification of three groups of risks in LPI. Then, a case study was conducted in one of the companies represented in the survey, in order to identify examples of relationships between the risks. Multiple sources of evidence were used in the case study, such as interviews, observations and documents analysis. Findings – The risks that affect LPI were grouped into three categories: management of the process of LPI, top and middle.
Vibration Isolator Design for Space Application Based on Multiobjective Optimization Method

A multiobjective optimization based vibration isolator design for space application is described. It is common to use passive isolator and isolate the platform noise in space applications. The design of a passive isolator involves a trade-off between the resonant peak reduction and the high frequency attenuation. The equation of motion and transfer function model for single-stage and two-stage connector model is derived by using basic principle. The multiobjective optimization model is proposed, where the design variables are the damping coefficients and stiffness coefficients, the objective functions are the resonant peak reduction and the high frequency attenuation, and the constraints are the natural frequency of the connector. The multiobjective optimization problems for the design of the passive isolator are solved by using the multiobjective evolutionary algorithm based on decomposition (MOEA/D). The Pareto front obtained can provide multiple candidate solutions for the designer. The method is effective for the design process of the passive isolator.
A configuration approach for selecting a data warehouse architecture.

Living in the Information Age, organisations must be able to exploit their data alongside the traditional economic resources of man, machine and money. Accordingly, organisations implement data warehouses to organise and consolidate their data, which creates a decision support system that is “subject oriented”, “time variant”, “integrated” and “non-volatile”. However, the organisation's ability to successfully exploit their data is determined by the degree of strategic alignment. As such, this study poses the question: how can a data warehouse be successfully and demonstrably aligned to an organisation's strategic objectives? This thesis demonstrates that strategic alignment can be achieved by following a new "top down" data warehouse implementation framework, the Configuration Approach, which is based upon determining an organisation's target configuration. This was achieved by employing Miles and Snow's Ideal Types to formulate a questionnaire that reveals an organisation's target configuration in terms of its approach to the Entrepreneurial, Administration and Information Systems challenges. Crucially, this thesis also provides the means to choose a data warehouse architecture that is wholly based on the organisation's target configuration. The Configuration Approach was evaluated using a single case study undergoing a period of strategic transformation where the implementation of a data warehouse was key to its strategic ambitions. The case study illustrated how it is possible to articulate an organisation's strategic configuration, which becomes the key driver for building a warehouse that demonstrably supports the resolution of its Entrepreneurial and Administration challenges. Significantly, the case study also provides a unique opportunity to demonstrate how the target configuration helps organisations to make the right choice of data warehouse architecture to satisfy the Information Systems challenge. In this case, the Configuration Approach provides a basis for challenging the architectural choices made by a consultancy on behalf of the participating organisation. Accordingly, it can be asserted that data warehouses are strategic investments, if implemented using the Configuration Approach.
Monopulse Estimation of Unknown Polarization for Conformal Phased Array with Arbitrarily Oriented Dipoles

In this paper, a novel monopulse estimator is proposed to surmount obstacles caused by unknown polarized pattern and the difference among each dipole orientation. Polarized pattern often alters the phased array response and we could hardly recover it if we known nothing about polarized parameters. The sum and difference beamforming of conformal phased array is affected due to the difference among each dipole orientation. Therefore the conventional monopulse estimator is dumped in this circumstance. The method proposed in this paper is a remarkable estimator based on maximum likelihood methodology. In this method, polarized parameters are considered as a part of desired signal and the least-squares solution of desired signal is obtained. With the desired signal solution, the likelihood function with respect to direction is derived at first. Then from the above, Jacobian and Hessian matrix of likelihood function is deduced. The boresight is considered as the initial direction value and the estimator of desired signal direction is obtained by Newton's formula. Finally, the polarized parameters are estimated by least-squares method using the direction estimator. The root-mean-square error (RMSE) of angle estimation is acceptable when prior polarized information is completely unknown. Polarized parameters are estimated by similar technique after we find out azimuth and elevation. Our research fills a gap of monopulse estimation with arbitrary polarization and diverse dipole arrangement.
What are standardized equations for acceptance of hi-pot tests and for voltage drop?

Long power cables and large electric machines require different application techniques from most electrical wiring. The first topic discussed is evaluation of insulation for continued use. The second area is selection of conductor size considering temperature and voltage drop. The hi-pot evaluation is primarily a maintenance function, while the voltage drop procedure is primarily a design practice. For the first topic, high potential (hi-pot) tests are often conducted on power cables and large electric machines. However, there has been no standardized method of determining if the insulation is acceptable. Various methods have tried to compare leakage current between conductors, use a fixed limit on leakage current, or comparison with previous tests. Each has its advantages and limitations. From empirical data and diverse experience, the authors have developed a numerical technique that will indicate impending failure. The procedure is mathematically rigorous but can be practically applied. It is very applicable to computer controlled hi-pot systems as well as manual systems. The second topic is the voltage drop for long conductors. The authors have applied numerous considerations to develop a simple relationship that can be readily applied. It incorporates wire diameter, length, current, number of phases and temperature correction, with permissible voltage drop.
Compact shorted inverted-L antenna with circular polarisation for RFID handheld reader

Two shorted inverted-L radiating elements are located on the orthogonal corner of the square substrate and connected to each output port of a Wilkinson power divider. A shorted inverted-T strip is placed on the other corner of the square for a perturbing resonator to generate circularly-polarised (CP) radiation in the UHF band. Proper adjusting of the horizontal and vertical lengths of the inverted-T strip will differentiate two orthogonal linearly modes with 90° phase difference for a good CP radiation. Simulated and measured results indicate that the proposed structure can achieve circular-degree polarisation operation. A measured impedance bandwidth (VSWR ≤ 2) of about 16.4% (810–960 MHz) and a 3 dB axial-ratio (AR) bandwidth of about 4.4% (890–930 MHz) at 915 MHz were obtained.
Is the Ambidextrous Advantageous When using Large Touchscreens?

Conducting touch gestures on large format touchscreens for personal computers (PCs) is known to cause greater body discomforts than that from using a traditional PC due to frequent hand movements in floating arm postures. It was of interest whether the discomforts would vary depending on user’s handedness. The current study investigated potential associations between user’s handedness and subjectively assessed discomforts during the use of a 23” touchscreen personal computer. Twenty two participants were grouped by their handedness (left-handed, ambidextrous, right-handed), and conducted a typical web browsing task for 30 minutes while their hand/arm movements and subjective body discomfort ratings were periodically collected. Results show that ambidextrous participants used both hands more evenly than the other two groups, and they also reported significantly less body discomforts (p<0.05) compared to the others. To reduce physical discomforts and prevent musculoskeletal problems associated with the extended use of touchscreens, alternating hands in conducting touch gestures could be recommended.
Application of Artificial Neural Network for Modeling of Mechanical Cooling Tower

The objective of the study is to focus on the application of the artificial neural network to configure a heat-radiating model for cooling towers within the parameters of fluctuating in air flow or cooling water flow. To achieve the objective, a cooling tower heat balancing equation have been used to instill the correlations between a cooling tower cooling load to the four predefined parameters. Based on the premise established, the parameters of a cooling tower’s air flow and cooling water flow in a modulated process are utilized in an experimental system for collecting relevant operating data. Lastly, the artificial neural network tool derived from the Matlab software is utilized to define the input parameters being – the cooling water temperature, ambient web-bulb temperature, cooling tower air flow, and cooling water flow, with an objective set to instilling a cooling tower model for defining a cooling tower cooling load. In addition, the tested figures are compared to the simulated figures for verifying the cooling tower model. By utilizing the method derived from the model, the mean error of between 0.72 and 2.13% is obtained, with R2 value rated at between 0.97 and 0.99. The experiment findings show a relatively high reliability that can be achieved for configuring a model by using the artificial neural network. With the support of an optimized computation method, the model can be applied as an optimization operating strategy for an air-conditioning system’s cooling water loop.
Solar dynamic power for Earth orbital and lunar applications

Development of solar dynamic (SD) technologies for space over the past 25 years by NASA Lewis Research Center brought SD power to the point where it was selected in the design phase of Space Station Freedom Program as the power source for evolutionary growth. More recent studies showed that large cost savings are possible in establishing manufacturing processes at a Lunar Base if SD is considered as a power source. Technology efforts over the past 5 years have made possible lighter, more durable, SD components for these applications. A review of these efforts and respective benefits is presented.
Current Understanding of the Transport Behavior of Hydrogen Species in MOS Stacks and Their Relation to Reliability Degradation

We review recent experiments that suggest a comprehensive model for the reversible hydrogen (H) transport between the poly-Si interface and the oxide/Si interface of MOS stacks. The H diffusion in intact model MOS structures is probed by H depth profiling via resonant N-H nuclear reaction analysis (NRA). It is demonstrated that MOS device degradation correlates with H accumulation in the oxide/Si interface region. A specific ultra-thin oxynitride is discovered in the poly-Si/oxynitride interface as well as in the near-surface region of N2-annealed nitride films and shown to function as a potential H-storage layer. The interfacial storage layer between the poly-Si gate and the oxynitride dielectric of MOS transistors is found to contain two kinds of H species, which are mobile and stable, respectively, versus irradiationinduced relocation. The mobile H, if stimulated by energetic carriers, migrates across the gate films and relocates to the SiO2/Si interface, causing device instabilities. Understanding this basic hydrogen transport behavior allows conceiving fabrication countermeasures to improve the device reliability.

Accounting for segment correlations in segmented gamma-ray scans

In a typical segmented gamma-ray scanner (SGS), the detector`s field of view is collimated so that a complete horizontal slice or segment of the desired thickness is visible. Ordinarily, the collimator is not deep enough to exclude gamma rays emitted from sample volumes above and below the segment aligned with the collimator. This can lead to assay biases, particularly for certain radioactive-material distributions. Another consequence of the collimator`s low aspect ratio is that segment assays at the top and bottom of the sample are biased low because the detector`s field of view is not filled. This effect is ordinarily countered by placing the sample on a low-Z pedestal and scanning one or more segment thicknesses below and above the sample. This takes extra time, however, We have investigated a number of techniques that both account for correlated segments and correct for end effects in SGS assays. Also, we have developed an algorithm that facilitates estimates of assay precision. Six calculation methods have been compared by evaluating the results of thousands of simulated, assays for three types of gamma-ray source distribution and ten masses. We will report on these computational studies and their experimental verification.

Global Optimal Design and Dynamic Validation of an Independent Double Wishbone Air Suspension Using Genetic Algorithm

In view of the drawbacks of the traditional optimal methods in the suspension structure optimization, this paper elaborates a genetic algorithm (GA) based global optimal design so as to improve the vehicle performance. Firstly, an independent double wishbone air suspension (IDWAS) is constructed. After defining the linkage relation of the guide mechanism of the IDWAS, the model is verified followed with the parametric design. Furthermore, in consideration of the prescribed targets of the vehicle kinematics, the wheel alignment parameters (WAPs) are selected as the objectives of the optimal design of the vehicle kinematics. Apart from the kinematic analysis of the IDWAS, dynamic analysis before and after optimization as well as the traditional independent double wishbone suspension (TIDWS) are also conducted. Numerical results show that the changes of the WAPs are within a certain range and the guide mechanism follows the prescribed constraints. Simulation results show that the IDWAS is superior to the TIDWS, while the optimized IDWAS has a slight improvement as compared to the original IDWAS in dynamic performance of the suspension.
