A 2D Oil Spill Model Using Radial Basis Function Collocation MethodA 2D Oil Spill Model Using Radial Basis Function Collocation Method

Автор: Tunay Carpar

In this study, a two dimensional numerical advection diffusion model was developed to simulate an oil spill and to determine the fate and transport of oil on a sea surface. A meshless numerical scheme based on the Radial Basis Function Collocation method (RBFCM) was employed for solving the transport equation in the model. To evaluated the performance of the model, a benchmark problem and an application for the Marmara Sea were investigated. For the benchmark problem, several RBFCM solutions were investigated and compared to the analytical solutions. For the Marmara Sea application, only surface currents were used to drive the oil slick. Surface current profile was generated by interpolation of the data received from Office of Navigation, Hydrography and Oceanography using the Radial Basis Function Collocation method. Physical parameters of oil for diffusion, evaporation, vertical dispersion, shoreline deposition were based on literature values. Sensitivity analysis to key diffusion...

A 2N Approach for Lossless Image CompressionA 2N Approach for Lossless Image Compression

Автор: Javvadi N. V. R. Swarup Kumar

Image compression techniques play a vital role in image processing. There are several lossy and lossless coding techniques developed all through the last two decades. Although very high compression can be achieved with lossy compression techniques, they are deficient in obtaining the original image. While transmitting an image we have to reduce the size of the image in order to decrease the time needed to transmit the image. There are so many compression methods have been introduced to compress the image but exact image can recover by lossless compression technique. Here introduced a new lossless compression technique which even better reduces the entropy there by reducing the average number of bits with the utility of Non Binary Huffman coding through the use of 2N approach. The 2N approach proposed through our new approach can be largely utilized for all other encoding schemes for images.

A book on decision making for event-driven maintenanceA book on decision making for event-driven maintenance

Автор: Aashish Khaira and Amit Kumar Jain

Today most conventional maintenance strategies are purely reactive, corrective (fixing or replacing equipment after it fails) or time -scheduled. These strategies are not well adapted to the control of the global performances of a manufacturing system. Therefore it is now necessary to move from traditional maintenance strategies to new ones like Opportunistic maintenance. Opportunistic maintenance works out to be the perfect remedy, which utilizes the opportunity of system shutdown or module dismantle to perform any maintenance required in the immediate future and saves a substantial amount of system down-time. This book presents an intelligent decision making method of how to decide whether a particular component requires opportunistic maintenance or not, and if so how cost effective this opportunity-based maintenance will be when compared to a probable future grounding. In this book we are discussing opportunistic maintenance as an alternate strategy for maintenance along with steps...

A CBR based new approach towards cost estimation quality enhancementA CBR based new approach towards cost estimation quality enhancement

Автор: Meenu Dhiman and Rakesh Kumar

Software cost estimation is the process of predicting the effort required to develop a software system. Many estimation models have been proposed over the last 30 years. Models may be classified into 2 major categories: algorithmic and non-algorithmic. Each has its own strengths and weaknesses. A key factor in selecting a cost estimation model is the accuracy of its estimates. Unfortunately, despite the large body of experience with estimation models, the accuracy of these models is not satisfactory. The work includes comment on the performance of the estimation models and description of several newer approaches to cost estimation. A CBR based efficient search technique has been introduced so that can help to obtain the best result.

A Closer Look Towards Arithmetic AlgorithmsA Closer Look Towards Arithmetic Algorithms

Автор: Barun Biswas,Krishnendu Basuli and Samar Sen Sarma

Computer of the day deals with binary digits. When the project started we were initially with complexity of arithmetic algorithm. Classical Booth?s algorithm is universally accepted as it is not prone to sign changing. However we must remember that computer can do whatever we ask to do. We basically observed that Strassen matrix multiplication algorithm where there is any place to play with it. We started thinking. We know that no finite state machine can multiply arbitrarily large pair of binary numbers. We compromise and consider binary number n to be adjustable according to machine consideration both in time and space. We started our experiment with checking shift operation in multiplication by considering multiple shift at the same time. The result was encouraging. Our effort is supported by detailed performance profile analysis. The work is an initial effort. The extension of the work is possible and we are sure we will preside to new revolution in near future

A Comparative Study of Cyclic Constitutive Models for ConcreteA Comparative Study of Cyclic Constitutive Models for Concrete

Автор: Farhad Aslani

Experimental programs in laboratories give real results to identify nonlinear behavior of reinforced concrete structures but they are limited to knowledge of particular cases under restricted structural dimensions, sizes, shapes, loading and boundary conditions but the computational simulation approach has no limit to its application. Constitutive models are developed to simulate the dynamic nonlinear response of concrete and steel reinforcement subjected to cyclic loading varying randomly in magnitude. The behavior of structural concrete under monotonic loading is affected by important material aspects including cracking, crushing, tension stiffening, compression softening and bond slip. Reversed cyclic loading introduces further complexities such as stiffness degradation in concrete and the Bauschinger effect in reinforcing steel. In this study the validity and reliability of some proposed constitutive models for concrete considering general loading (i.e. cyclic, monotonic, partial...

The pressure vessel design methods can be divided into two basic categories regardless of which code or standard they are inherent from, namely the Design by Rule and the Design by Analysis. When doing Design by Rule, the overall dimensions and loads are specified and wall thickness is calculated by predefined procedures, formulas and charts. When doing Design by Analysis, the vessel geometry and overall dimensions are defined, and allowable loads are evaluated through detailed structural analysis. Problems might arise when the various methods produces different answers to identical design problems. When conducting design procedures a component could be designed by the following methods: By rule, By classical interaction analysis, With an elastic FEA using a shell model, With an elastic FEA using a solid model and linearization procedures, By FEA limit analysis or By FEA plastic analysis. Most designers might feel that the methods are presented in an order of...

A CUDA based Parallel Implementation of Speaker Verification SystemA CUDA based Parallel Implementation of Speaker Verification System

Автор: Mohammad Azhari

Speaker Verification (SV) is system that validates the identity of a claimed person by his/her voice. Optimization of the SV systems can help to decrease development time. Interestingly, the techniques can be easily optimized using parallel implementation. The existence of a massively parallel computing technology such as NVIDIA's Compute Unified Device Architecture (CUDA) has changed the face of computing in the recent years. Currently having some of the most efficient ratings on supercomputer lists indicates that today’s Graphical Processing Units (GPU) are fairly accepted for scientific computing purposes considering their low power consumption. In this book we perform a research on parallelizing an speaker verification technique using CUDA technology and we compare its benefits and downfalls to the traditional single-thread or parallel CPU implementations. The implementation scenario should help clarify some of the most important but rarely spoken challenges using parallel...

A Differential Absorption Model For Remote SensingA Differential Absorption Model For Remote Sensing

Автор: Shivam Shah

Air pressure is one of the most important parameters regularly measured at surface meteorological stations. With developments of remote sensing methods, especially in airborne and satellite remote sensing techniques, large-scale and global surface pressure measurements significantly lag behind other important parameters, such as surface temperature. Researchers have suggested using satellite oxygen A-band methods (both passive and active) to measure the pressure. The active instruments rely on the operation of complicated highly stable laser systems on a space platform and are thus technically difficult, while passive methods are restricted to daytime measurements and areas of low cloud cover. Thus, there are still no real remote sensing measurements of surface pressure, even in experimental stages. This study considers active microwave techniques at strong O2 absorption bands (around 50–56-GHz) for the remote sensing of surface air pressure. At these frequencies, the total extinction...

A Finite Element Model of Warm Metal Powder Compaction ProcessA Finite Element Model of Warm Metal Powder Compaction Process

Автор: M. M. Rahman and A. K. Ariffin

The development of finite element model for the simulation of a complete warm forming process of powder sintered component is presented here. The material constitutive laws were derived based on a continuum mechanics approach. The process of green compact generation was represented by a large displacement based finite element formulation. Three constitutive relations, i.e., Mohr-Coulomb, Elliptical Cap, and combination of these two yield models were used to describe the deformation behaviour of the powder mass during compaction. However, an Elliptical Cap model was shown to be the most appropriate. A plasticity theory of friction was employed in the treatment of the powder-tooling interface. The Roscoe-Burland criterion was used to describe the densification and dimensional change of the compact during the sintering. The staggered-incremental-iterative solution strategy was established to solve the non-linearity in the systems of equations. The numerical simulation results...

A GA approach to the Optimization of Laser Beam Welding processA GA approach to the Optimization of Laser Beam Welding process

Автор: G.Harinath Gowd

Automation of a manufacturing process has become the order of the day in industries in order to achieve high production rates and high quality of finished components. However, in order to automate a process it is essential to find the best values of process variables. In turn, this requires the establishment of precise quantitative relationships between the process control variables and the chosen output responses. The scope of the proposed work is intended to develop such relationships for the chosen responses in terms of input variables and utilizes those developed relations to find the optimal set of process variables in Laser welding and Laser machining. Once the optimal values are found, then the process could be automated based on them there by reducing the manpower thus reduces the welding cost.

A Generic BI Application for Real-time Monitoring of Care ProcessesA Generic BI Application for Real-time Monitoring of Care Processes

Автор: Shirley Baffoe

Proper management of patient wait times and service times may support smarter and proactive decisions in managing patient flow. Those decisions usually impact on resource allocation and hospital process management. For example, how can the hospital know where to provide more staff to reduce the increased wait times in the hospital? Given that additional resource allocation comes with increased cost and there are competing priorities, the hospital decision makers need to determine which course of action is the most appropriate one to take. Decisions made based on information within a departmental silo may not be the optimal one. Such decisions may only transfer the patient flow bottleneck to another department. In this thesis, we propose a state monitoring engine (SME) for inferring and managing states that is an improvement over traditional CEP approaches. Our proposed engine is based on an application meta-model for care process monitoring developed by (Baarah & Peyton, 2012). In...

A Growth Model in the Use of LEDs in Commercial Lighting DesignA Growth Model in the Use of LEDs in Commercial Lighting Design

Автор: Tom Page

Light Emitting Diodes (LEDs) are well documented for their energy efficiency and usage diversity, but their poor colour rendering and colour temperature has slowed their adoption for domestic use. Expensive per unit in comparison to traditional light sources, they nonetheless dominate the research and development labs of some of the world''s leading lighting manufacturers. This research project explores what it is that has got the lighting industry so excited about this technology that was discovered almost 90 years ago, whether consumers will share their enthusiasm and aims to establish the extent to which LEDs have revolutionised the lighting industry. The author sourced reliable data from LED manufacturers and energy efficiency regulators, using lighting-specific magazine articles to ensure that all data used is current at the time of writing. Once a statistical comparative is formed, the opinions of lighting industry experts are considered and compared, and drawn on to form a...

A Hand Book on Fabrication Aspects on MEMS based Pressure SensorsA Hand Book on Fabrication Aspects on MEMS based Pressure Sensors

Автор: Parvej Ahmad Alvi

This book is designed as an introduction for the graduate students and researchers who want to understand the trends of MEMS materials and devices. Particularly, this book describes the experimental view of the fabrication of a thin membrane over a conical V-shaped cavity using front side lateral etching technology that proposes a novel front side etching fabrication process for silicon based piezoresistive micro- pressure sensor. As far as the fabrication process is concerned, this technique successfully accomplished a front side etching process laterally to replace the conventional back-side bulk micro-machining. This novel structure of micro pressure sensor can achieve the distinguishing features of the chip size reduction and fabrication costs degradation. This book covers the principles, tools and methods for determining the reliability of micro-electro-mechanical (MEMS)materials, components and devices.

A hybrid adjoint approachA hybrid adjoint approach

Автор: Thomas Taylor

Adjoint-based techniques can provide the sensitivity of an objective function to any number of parameters of a simulation inexpensively at roughly the cost of a single additional flow calculation. This information can be used to perform sensitivity analyses, aerodynamic shape optimization, and to estimate the error in an objective function due to the numerical discretization. Existing approaches to derive the numerically discretized adjoint equations involve the so-called discrete and continuous methods, which differ in the order at which the discretization and linearization steps are performed. The effect of these contrasting approaches is that they have both strengths and weaknesses over each other in the form of the complexity of the formulation and the computational expense of the solution. In this work a hybrid approach is developed that combines elements of the continuous and discrete methods with the intention of capturing the advantages of both: reducing the time spent on...

A Look at The Impacts of Urban Slums on Surface Water ResourcesA Look at The Impacts of Urban Slums on Surface Water Resources

Автор: Isaac Monney

Distress migration of the poor in rural areas to urban areas in the developing world has resulted in the proliferation of urban slums. These are areas characterised by poor housing, lack of access to safe water and improved sanitation, deplorable environmental conditions, among others posing adverse effects to human health and the environment as well. The lack of improved sanitation is particularly a big problem in slums because solid waste, excreta and untreated wastewater are discharged directly into surface water resources draining their catchments. In order to avoid pollution possibly derived from these sources, with implications for drinking water sources, it is necessary to understand the sources, composition and loads of chemical and microbial contaminants that emanate from the insanitary conditions that prevail in slums. This book looks at the extent of pollution of surface water resources arising from these sources and the best practices to address this issue.

A Loudspeaker Integrator Designed to Control Mechanical VibrationsA Loudspeaker Integrator Designed to Control Mechanical Vibrations

Автор: Nicholas Orenstein

Vibration control by a speaker integrator is necessary to maintain optimal dynamic deflection of the cabinet wall and to isolate the speaker driver from room feedback. The prior art, however, fails to decouple these concerns yet address them simultaneously. Mathematical models are developed and presented to accurately describe a speaker's playback in a dynamic room environment. A prototype design is then developed and hand built in which a tuned two-degree-of-freedom mechanical system prevents additional mechanical impedances and a spiked, damped stand isolates the system from room effects while raising the driver to ear height. This work hopes to motivate the inclusion of an integrator in the setup of all sound systems, especially those of audiophile quality.

A Manufacture System for a Self-Sufficient Lunar ColonyA Manufacture System for a Self-Sufficient Lunar Colony

Автор: Irina Westerberg

Why explore a dead planet? Is it worth the efforts? The great advantages by doing advanced scientific experiments and observations on the far side of the moon are the lack of atmosphere and it is shielded from the electromagnetic noise and light emitted by Earth. For many years now, a large number of scientists and engineers have been planning in detail for that possibility. The results are carefully gathered and valuated from several different samples collected from the Moon and even advanced Satellite photos shows that it is possible to build a self-sufficient Lunar Colony. Most of the needs for this colony can be supported by the moon itself. The Regolith (lunar dust) contains almost every element we need for our survival. The issue is to adapt it by mining activities and the capability to store it in a proper way. The size of the colony would be at least five hundred people of various ages, gender, and skills. It is a hardworking and dangerous existence and both technical...

A MB-PULSED-OFDM System using DWPT for UWB WPAN EnvironmentA MB-PULSED-OFDM System using DWPT for UWB WPAN Environment

Автор: Choudhury Sasmita Das

Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) approach using UWB signals with short duration of pulses provide unique advantages in short-range high data rate WPAN physical layer applications, which include easy penetration through obstacles, high precision ranging and low processing power. Non-pulsed MB-OFDM system suffers from the frequency selectivity of the fading channels. MB-pulsed-OFDM is used eliminate heavy error correction coding for dense multipath frequency selective channel model. The IFFT module in the pulsed-OFDM transmitter is much less complex than the IFFT module in the normal OFDM because MB-pulsed-OFDM uses 32 subcarriers while normal MB-OFDM uses 128 sub-carriers. Each subcarrier has large side-lobes, requiring careful filtering and sufficient guard interval bands in a traditional MB-OFDM UWB system. Again Fourier based MB-OFDM signals only overlap in frequency domain. To overcome these aforementioned problems associated with MB-OFDM UWB system,...

A Micro and Macroscopic Study on Coalescing FiltersA Micro and Macroscopic Study on Coalescing Filters

Автор: Rahul Bharadwaj

Coalescing filters can remove condensation aerosols and are used for major industrial and automotive applications. Coalescing filters capture and coalesce liquid droplets which then drain the liquid out of the filter under the effect of gravity. A good coalescing filter should have a low saturation/liquid hold up in order to have low operating pressure and longer filter life. Liquid saturation directly influences the porosity of the filter which in turn dictates the resistance to airflow through the filter. The efficiency of the filter is highly dependent on the filter media and the filter design however the orientation of the fibers in the media and the orientation of media layers in a filter design can have a huge impact on the coalescing of liquid in a filter. This book describes a microscopic and macroscopic study on coalescing media and how different fiber and media layer orientation can impact the coalescence of liquid aerosol.

A Model Based Framework for Object Detection via Data TransformationA Model Based Framework for Object Detection via Data Transformation

Автор: Peifang Guo and Prabir Bhattacharya

The dynamic synthesis of nonlinear feature functions is a challenging problem in object detection. This book presents a combinatorial approach of genetic programming and the expectation maximization algorithm (GP-EM) to synthesize nonlinear feature functions automatically for the purpose of object detection. The EM algorithm investigates the use of Gaussian mixture which is able to model the behaviour of the training samples during an optimal GP search strategy. Based on the Gaussian probability assumption, the GP-EM method is capable of performing simultaneously dynamic feature synthesis and model-based generalization. The EM part of the approach leads to the application of the maximum likelihood (ML) operation which provides protection against inter-cluster data separation and thus exhibits improved convergence. The experimental results show that the approach improves the detection accuracy and efficiency of pattern object discovery, as compared to some state-of-the-art methods for...

It would have been hard to achieve both goals in a general way in few months, but limiting the load pattern to the flexural tests on specimans and using realistic assumptions on the deformation and crack opening in a cross section it has been possible to build a simple procedure able to evaluate a realistic evolution of load vs. displacement diagrams, and toughness of the compositie material.
