A 2-D Numeric Model for Open-water Evaporation EstimationA 2-D Numeric Model for Open-water Evaporation Estimation

Автор: Xi Yao

To study the techniques for open-water evaporation reduction, this study develops an improved 2-D numeric model, based on the Penman-Monteith (P-M) equation. Some of the quantification methods of evaporation rate and the theory of boundary layer condition and the modelling of the water body temperature profile are reviewed. Using the existing data for the Wivenhoe Dam, Brisbane, Australia, we compare the estimations of the evaporation by the improved model and P-M equation before and after applying suspended covers, a particular evaporation reduction technique. The improved model provides more accurate estimation in every respect, including monthly/annual evaporation and surface water and water column temperatures. In particular, it solves the inability of the P-M equation to model the evolution of atmospheric condition along the wind fetch and the water column temperature profile. The modelling results and the pros and cons of the improved model are discussed. Further studies are...

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 Case Study of the Use of BIM and COBie for Facility ManagementA Case Study of the Use of BIM and COBie for Facility Management

Автор: Salil Jawadekar

For decades construction technology has seen an upward trend of improvement which has resulted in greater efficiency. This has been driven by the need to minimize construction costs and maximize profits. But what happens when the dust settles and the occupants move in? Several studies have shown that it is the building lifecycle where maximum wastage occurs and most losses are incurred. This paper discusses some of the technologies being used today and their initial results to streamline building performance, using the same tools and data generated and used during construction. The study focuses on three cases where this processes are at different stages of culmination, and tries to arrive at a general conclusion about their performance with future possibilities of statistical analysis once hard data is generated.

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 Communal Ground Source Heat Pump Feasibility AssessmentA Communal Ground Source Heat Pump Feasibility Assessment

Автор: Neil Langman

This work reviews and analyses design options used to assess the feasibility of a Ground Source Heat Pump (GSHP) to supply heating to twelve flats. Incentives for communal heating and renewable energy are examined, as are grants and schemes provided to assist uptake of GSHP systems. Four elements of GSHP system design are evaluated: heating load, pump size, borehole array and heat delivery system. The aim is to determine optimal design by minimising energy demand, land use, material use and project costs, whilst maximising system efficiency. Peak Load calculations and various borehole options are analysed using software simulations. Energy demand is evaluated for pumps and heating delivery systems using calculated methods, and literature review. Minimising materials and equipment, whilst maximising system efficiency is analysed by comparing design options.

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...

In South Africa, the levels of unemployment and poverty are extremely high and these are two of South Africa''s most pressing problems. Over the past 28 years several major programmes have been initiated in South Africa to counter unemployment and poverty. This did not solve the unemployment problem. Since 1994 the African National Congress (ANC) government has implemented large-scale programmes with similar objectives to those before 1994. After an analysis of the theoretical premises and implementation of labour-intensive public works programmes in Africa, the thesis critically evaluated several pre - and post - 1994 large-scale development programmes in South Africa. A major conclusion is that the pre-1994 lessons were not taken into considerations in the post-1994 programme planning and implementation. Based on the research, the author has derived a six phase Programme Management Framework for Development Programmes. This framework embodies a long-term...

The financing needs of contractors, especially emerging contractors, need to be explored. In the case of the(SMMEs') within the contracting sector, a type of "finance-PLUS" arrangement, which sees the lender, or an intermediary, offer additional support services to emerging enterprises, would be worth exploring. There are various perspectives and opinions on the format and context of the contribution. One of these perspectives embraces the obstacles involved in the entrepreneurial process hindering contribution and economic catalisation.

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 Genetic Algorithm for VLSI FloorplanningA Genetic Algorithm for VLSI Floorplanning

Автор: Anmol Shahani,Nitish Natu and Abbas Badami

VLSI design suffers from high design complexity and a large number of optimization objectives requiring hierarchical design approaches and multi-objective optimization techniques. The floorplanning stage of the design cycle becomes highly important in hierarchical design methods. The classical floor planning techniques use block packing to minimize chip area, by making use of algorithms like B-TREE representation, simulated annealing. To get an optimal solution it is imperative to choose an efficient algorithm. In this work, a genetic algorithm based floorplanner has been developed.

Mine safety is of paramount concern to the mining industry. In this sense the generation of a Geographic Information Systems (GIS) which can administrate relevant spatial data efficiently is a very vital issue for underground mining safety. In an effort to achieve a balance of safety and productivity, GIS can contribute to the creation of a safe working environment in underground (U/G) mining. Such a system should serve to a continuous risk analysis and be designed for applications in case of emergency. The process comprises first the safety concept as the application domain model and then a conceptual model being generated in terms of Entity- Relationship Diagrams. After the implementation of the logical model a user interface is developed and GIS is tested. The analysis should be useful for professionals in Underground Mining Safety field and GIS based applications, or anyone else who may consider utilizing the system for mining industry.

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...

Support Vector Machines (SVM) are known as the state of the art learning algorithms. Although they are called as the state of the art learning algorithms, the kernel functions take an important place when the SVM performance is the main concern. Recently Chebyshev kernel has been proposed as a good alternative to the well known and used Gaussian kernel. Therefore in this book we studied this kernel functions as well as several other kernel functions, and compared their performances. We also proposed a generalization method to use Chebyshev kernels on vector inputs directly. Moreover, we also discussed some properties of Gaussian kernels when used with SVM.

A Liquid Desiccant Air Conditioning SystemA Liquid Desiccant Air Conditioning System

Автор: Thosapon Katejanekarn

In tropical, hot and humid climates where temperature and humidity level are high, air conditioning (AC) systems are necessary for providing thermal comfort to building occupants. For an air conditioned space that needs outside air ventilation to maintain indoor air quality, the ventilation air can bring sensible heat ratio (SHR) of cooling load well below 0.7 since it accounts for as high as 80% of total latent load in the space. The cooling load SHR below this value cannot be handled effectively by conventional AC systems. Handling sensible and latent load separately using a hybrid scheme is an interesting option. A desiccant system can handle the latent load while a conventional system can handle mainly the sensible load. This could help reduce overall energy consumption and provide effective control of indoor air condition. This book presents a theoretical and experimental investigation of the use of a liquid desiccant (LiCl) AC system in tropical Thailand. The system treated...
