A Framework based on Human-Machine Interfacing for Mouse Cursor Movement with Human Eye Ball

×Abstract

‘Control’ is indeed a revolutionary field in science and a lot of research has been focused on forming digitally automate world, having all protocols controlled via microprocessors with great accuracy, perfection and efficiency, nullifying human errors. With the emergent of technology, number of computer devices is cumulating every day. For this reason, we propose an interactive framework; Mouse Cursor Controller (MCC) which controls the movement of mouse cursor with the rotation of human eye ball. The proposed framework requires the detection of face, tracking of eye balls using template matching, storing consecutive camera captured frames having eye ball’s positions and comparing this data, generating an error signal used as an input for mouse cursor’s position. This error signal is fed to the mouse driver and hence location of the cursor is updated accordingly. The other proposed frameworks in this field incorporates; Electrooculography sensors mounted around the human eye taking signal from eye muscle movement and varying cursor’s location consequently. The techniques applied in these frameworks are not appropriate because they are not autonomous. Moreover, they do not ensure efficient human-machine interfacing. On the other hand, our proposed framework of eye balls tracking provides an autonomous human-machine interface. The proposed framework integrates the useful information extracted from camera captured frames focusing the eye-ball position for accurate maneuver detection; instead of determining the movement of eye-ball using sensors and feeding the result for cursor’s positioning; a direct link is developed between machine’s hardware and human’s eye which minimize the hardware requirements. Moreover, this technique is more efficient, as increasing the number of frames per second, enhances the precision and monitors extremely small positional changes creating a perfect and swift response accordingly. Furthermore, the proposed framework is beneficial for hand free computing.

Computer Interaction Using Laser Pointer

×Abstract

In recent years high quality interaction devices have become very popular in our environment. The industries are also currently undergoing rapid change and various technologies have been explored to enable these capabilities. Projection systems using beam projectors and laser pointer became the ubiquitous infrastructure for command technology. Group meetings and other non-desk situations require that people should be able to interact at a distance from a display surface. This paper presents new interaction techniques that use a laser pointer to directly interact with display on a large screen. The camera is subsequently used to detect the position of the pointing device (such as a laser pointer dot) on the screen, allowing the laser pointer to emulate the pointing actions of the mouse. The laser pointer will behave as an active point on the projected display where the user can interact. This vision-based system is augmented with a natural interface that enables the user to interactively refine the suggested rectification. This makes it very easy for users to execute fast and Continuous commands. The interaction model developed behaves like a “smart interaction system.” The vision based interaction system requires no special hardware and runs on a standard computer.

Effect of Shot -Peening and Imidazole on The Corrosion Resistance U -Bend SS316L

×Abstract

This study is an examination on the combined effect of shot peening and application of corrosion inhibitor on the corrosion behavior of Austenitic stainless steels (316L) in chloride solutions under constant stress. The constant stress is applied to the samples by U-bending process. The surface hardness of U-bended samples are improved by shot-peening process. The surface morphology of samples are analyzed in different testing and corrosive environments by using Scanning Electron Microscopy (SEM) and Optical Imaging Microscopy (OIM). Electrochemical techniques; open circuit potential (OCP), linear polarization resistance (LPR) and Tafel analysis are used to determine the reduction of the corrosion rate of samples by shot-peening and application of Imidazole as corrosion inhibitor in chloride environment. The results from the electrochemical tests indicate that the combined application of shot peening and Imidazole has resulted in a higher corrosion resistance behavior and hence less corrosion rate of SS316L in chloride environment and the overall efficiency of the material increases to about 58% using the combined application.

Assessment of the Integrity of Internally Corroded API Carbon Steel Pipelines

×Abstract

Carbon steel pipelines are renowned for its long-term resistance to the hydrostatic pressure of the transported fluid. Nevertheless, failure of carbon steel pipes can be catastrophic if not predicted or mitigated properly. One of the most common failure causes in carbon steel pipelines is corrosion of the pipeline inner and outer surfaces. The corrosion on pipeline walls will eventually lead to severe loss of material to a point which will cause complete loss of pipeline integrity

×Abstract

Carbon steel pipelines are renowned for its long-term resistance to the hydrostatic pressure of the transported fluid. Nevertheless, failure of carbon steel pipes can be catastrophic if not predicted or mitigated properly. One of the most common failure causes in carbon steel pipelines is corrosion of the pipeline inner and outer surfaces. The corrosion on pipeline walls will eventually lead to severe loss of material to a point which will cause complete loss of pipeline integrity.

This study will assess the burst pressure of predefined internal corrosion-defected API carbon steel pipelines through FEA using ABAQUS software. A parametric study considering a developed set of defect geometrical parameters, as well as the mechanical response of the pipe material, is conducted. The parametric study is performed through FEA to investigate the influence of the highlighted parameters to the overall burst pressure of the pipe. A closed-form solution was developed as a result of the parametric study for the influential parameters, which permits direct substitution of parameters to assess the defected pipe integrity.

Direct Solar Desalination Using Nano/Micro-porous Polymeric Membrane via Thin Film Evaporation

×Abstract

Evaporation from micro/nano structures is a ubiquitous phenomenon which plays an important role in nature and industrial applications, such as transpiration in plants, mammalian perspiration, electronic cooling and water desalination. Thin film evaporation from nanoporous membranes is a promising thermal desalination approach because it utilizes the passive capillary pumping of liquid to the evaporating interface and allows for high heat transfer rates due to the large evaporating area in addition to the capillary pumping driving force. In this study, solar energy was used as a heat source to evaporate seawater through in-house fabricated polyvinylidene fluoride (PVDF) nano/micro-porous membranes. Compromising between the available area for evaporation via changing pore size and the available material for conductive transfer of heat to the liquid thin film is complicated. Since more porous membrane increases the evaporation surface area and at the same time this leads to having less conductive material for heat transfer which at the end will reduce the evaporation rate. The main objectives of this study are, firstly to investigate the pore size effect on the vapor flux by fabricating flatsheet membranes via a phase inversion process with 12 wt% of PVDF and 500 µm thickness, and varying preparation parameters such as relative humidity and exposure time to achieve different pore sizes. Secondly to examine the thermal conductivity effect by blending different concentrations of fumed silica (1, 2, 3, 4, or 5 wt%) with the polymeric solution. The fabricated membranes were characterized by scanning electron microscopy (SEM), contact angle analyzer (CA), Fourier transform infrared spectroscopy (FTIR), capillary flow porometery (CFP), porosity and AFM, to further understand the observed thin film evaporation effects. The preliminary results showed, the mean flow pore diameter of the fabricated membranes are 117.2 nm, 123.3 nm and 206.6 nm and there porosity 28.4 %, 46% and 33% respectively. Also, the contact angle analyzer proved the hydrophobicity of these fabricated membranes since the contact angle was found to be above 95°.

Estimation of Power in High Altitude Freely Suspended Wind Turbine

×Abstract

Conventional wind turbines are restricted in its use due to certain limitations and challenges in its position. To use wind turbine efficiently and economically, it is required to overcome space requirements, noise, variation in air current and set up cost. This study attempts to design and fabricate suspended wind turbine to overcome the above stated hurdles. In this current work, the blades and the alternator are placed in the helium balloon housing which is suspended in the air and supported to the ground with tether. A tether made of conductive material is to transmit the generated power from the airborne housing to the ground base. Blades are made of aluminium and it ensures low rotational inertia. The proposed suspended wind mill in this study is able to generate power output which is comparatively cheaper than conventional wind turbines and also work will be able to cater the needs of electric power to remote areas and farms. Entire setup is modelled in 3D software Creo and the simulation is carried out using ANSYS software.

×Abstract

In Korea, construction waste has been increasing steadily due to the redevelopment of aging buildings, and problems with aggregate supply and demand have been increasing due to limited natural aggregate reserves. The recycled aggregate is a solution to this problem, but when used as a structural member, the cement paste attached to the aggregate surface causes low compressive strength and high water absorption rate, which lowers the reuse rate. Therefore, we are trying to confirm the applicability of CFT columns to the actual building structural members by filling the concrete with recycled aggregate. In this study, we developed 50 MPa concrete and fabricated 18 specimens of CFT columns filled with recycled aggregate concrete. The parameters are the type of steel tube and the ratio of concrete strength to concrete strength. The compressive behavior of the cyclic aggregate concrete filled CFT column was analyzed through the load - displacement curves and the performance was verified by the existing strength equation of the international code.

×Abstract

Many offshore structures are constructed in locations that are earthquake prone, and therefore, their seismic designs are required. However, in these cases, the selection of the acceleration time series for seismic design is difficult because recorded ground motions at the ocean bottom seafloor are limited. Recently, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) installed the ocean-bottom seismology network (DONET) at the offshore of Kii Peninsula in Japan. Twenty stations are recording three-component time series using accelerometers and seismometers. These time series are publicly available since 2012 at the JAMSTEC website (https://join-web.jamstec.go.jp/JSEIS/). This study selects and processes time series from DONET of representative shallow crustal earthquakes to develop an ocean bottom ground motion database for seismic design of offshore structures. To do this, the study reviews the instrument responses of the accelerometers and the seismograms to determine the frequencies that can be used in design. The recorded ambient noises are compared with the recorded ground motion to evaluate the quality of the signal, then filtering and baseline corrections are applied. The database will be composed of these reviewed and corrected time series. Finally, the corrected data are compared to the ground motion prediction models for shallow crustal earthquakes in Japan to understand the attenuations and site effects at ocean-bottom seafloor.

×Abstract

High strength bolts are used for connection of steel structures, and these are mainly of the torque shear type, which are designed to fracture by shear force at a predetermined torque. Although the manufacturers specify the clamping load of high-strength bolts dependent on diameter, no method has been available for measuring the clamping force at the onsite, when the bolt is actually fastened. Thus, a nondestructive testing method was developed the first in the world, that can measure the clamping load when fastening the bolt to an actual steel structure joint. There are two key elements in this method: the algorithm that synchronizes the load displayed in the clamping force meter taken form the existing analog device and measures the amount of cumulative electric energy required by the electric torque wrench, which is used for fastening the bolts at the time of measurement, and the prototype of the test device that embeds this algorithm. The technique developed in this study achieved a reliability within 5%, with respect to the actual clamping load.

Measuring the Scientific Impact Using Citation's Context

×Abstract

The impact of a publication and scientific evaluation is often measured by the number of citations it received. Citations plays very important role for scientific evaluation and for measuring impact of publications. In previous study only number of citations was counted for measuring publication impact and for scientific evaluation. However, a higher citation index does not necessarily mean that a publication necessarily had a positive feedback from citing authors, as a citation can represent a negative criticism. Here citation is a combination of positive, negative and neutral citations. We apply sentiment analyzer technique to rate citations as positive negative and neutral and then explore Conflict of Interest (COI) relationship by using Positive and Negative COI Distinguished Objective Ranking (PANDORA) algorithm and discover negative citation and weaken the associated citation strength. Our findings will help the authors to find out the impact of any author fairly by taking into account not only number of citations but also contexts of citations, whether it is cited positively or being criticized by some author.

Pitch Control Of Wind Turbines With Fuzzy Controller

×Abstract

As we know, Fossil fuels are declining day by day which has lead researchers to think about an alternate. As the world does not contain enough fossil fuels to supply electrical power to the whole world therefore Renewable energy is the new focus of modern researchers. Renewable energy especially solar and wind are widely used. Power quality is a very important problem in wind turbine. Due to the dynamic nature of this source the power quality issues occur. These issues mainly occur due to the variable nature of wind which consequently distorts the power output of the wind turbine. Add problems here if you want to but don’t make it long. It’s just a summary so keep it short. To tackle these problems control techniques are widely developed. In this research we have acquired the complete transfer function of wind turbine based power plant and step response based analysis has been made to evaluate the best pitch control technique. A PID and Fuzzy controller are implemented and step response is compared. Results clearly show that the Plant has best response under Fuzzy controller.

Investigating the Effects of Mechanical properties of Wood-Plastic Composites from MSW of China

×Abstract

In this paper, two Hybrid Thresholding schemes (TH-I and TH-II) have been proposed by the authors and successfully used in Wavelet Thresholding the Multitaper Spectrum for Speech Enhancement. The two Hybrid Thresholding schemes are formulated by incorporating the arctan function and exponential function suitably in Hard and Soft thresholding methods. To address the “musical noise” encountered in most of the frequency domain speech enhancement algorithms, Yi. Hu and P.C. Loizou have proposed the Wavelet Thresholding the Multitaper Spectrum Speech Enhancement with Hard and Soft Thresholding schemes. This paper investigates further improvement of Speech quality in terms of six objective quality measures using Discrete Wavelet Transform Thresholding the Multitaper Power Spectrum with the above proposed two Hybrid Thresholding methods. The performance of the new Hybrid methods is compared with the other thresholding methods. It is observed that, further improvement is observed with the proposed schemes when applied to noisy speech signals of low SNR (0dB) conditions. The results showed that, the use of Multitaper Spectrum estimation combined with wavelet Hybrid Thresholding yields better quality in terms of six objective quality measures. This Algorithm incorporates the noisy speech signal divided in to overlapping frames and each frame is subject to the Multitaper Power Spectrum estimation using either SLEPIAN(Discrete Prolate Spheroidal Sequences) or SINE Tapers and applied to the Wavelet Thresholding the Multitaper Spectrum based Speech Enhancement Algorithm and the enhanced speech is reconstructed in its time domain. Analysis is done using Daubechies and Symlet wavelets with different real world noisy environments as well as white Gaussian Noise. Six Objective quality measures are considered in this study to test the performance of the algorithm for enhanced speech quality and compared. The proposed two Hybrid Thresholding methods perform better than hard, soft, improved and modified improved thresholding methods for Wavelet Thresholding the Multitaper Spectrum based Speech Enhancement.
