Our society is today extremely dependent on computers. Not only PCs and laptops, but also the myriad of computers embedded in everyday things around us, such as vehicles, aircrafts, toys, and telephones. For many of these computers their correctness depends not only on the results of their computations, but also on the time at which the results are produced. Failure to produce a result within given timing boundaries may cause substantial economic losses, or even endanger human life. A worst-case execution time (WCET) analysis derives an upper estimate on the worst possible execution time of a computer program. Reliable WCET estimates are a foundation when it must be proven that an embedded system always will behave correctly, even in the...

This study appraises the development and assesses the methods for registration of medical images from multi-imaging modalities. In particular, problems of deformable anatomical structures are addressed. Different methods of image registration of deformable structures are evaluated. A warping- deformable model is proposed to tackle the problem of registration of CT (computed tomography) and MR (magnetic resonance) images of the abdomen with the liver as a target organ. The model can be extended to different imaging modalities and deformable structures alike. A two-step strategy is suggested where the global transformation is used firstly to determine the global mapping. In the second stage, local warping is implemented for the local...

This book provides a software prototype of Container Terminal Management system with the help of a Multi Agent systems technology. The goal during this research work was to solve the management issues residing in a CT. The software prototype can be implemented as simulation software that will help the Terminal Managers to take necessary decisions for the better productivity of CT. The CT's are struggling with taking proper management decisions. There are many policies implemented but the use of a certain policy at a proper time is the main issue. It is possible with simulation software to visualize the affects of decisions taken by the implementation of a policy and see the expected output. This can really improve the performance of a...

A spatial classifier is a model used to predict class labels for spatial entities based on their features, relationships to other entities and their corresponding features. One way to classify spatial data is to use a multi-relational framework, by transforming the spatial problem into a multi-relational one, and then applying existing methods. This transformation poses new problems. First, the spatial relationships are unknown, and the algorithm needs to determine which relationships and spatial features are important. Second, the effect of a single spatial entity is negligible when in the neighbourhood of thousands of other such entities, hence aggregation must be used. Third, properties of neighbourhoods, such as spatial trends, need...

Multimedia processing frameworks provide a comprehensive set of tools that greatly simplify the development of multimedia applications. "Traditional" frameworks provide pluggable black-box components that encapsulate different processing steps such as multiplexing or compression. The application is expected to use these building blocks to construct the full processing pipeline containing all individual transformations to be applied to the data. The work presented here proposes a very different approach to multimedia processing: Applications to formulate their media processing intent at a considerably higher level of abstraction, while the framework supplies the necessary infrastructure to dynamically translate these application requests...

This research proposes a quality of service (QoS) architecture for WiMAX, including a contention period management algorithm and a price-based scheduling framework. With a derived probability-based optimal contention window (P-OCW), we were able to devise a contention slot allocation algorithm to allocate contention minislots to flows based on P-OCW. In addition, a price-based scheduling framework was developed to provide price differentiation among users. This scheduling framework was designed to work using the TDD mode to take advantage of the adaptive subframe size as well as schedulers of adaptive price-based deficit round robin (AP-DRR) and price-based distributed deficit round robin (APDDRR). From simulation results, we strongly...

In a world where our every day life depends on what is going on in the gap between stimulus and reaction, Intruders could make the decision for you. Unless they are detected on time! Network security has been an issue since computers have been networked together. Lots of vulnerabilities, risks and threats came to the scene. An important security product that has emerged is Intrusion Detection Systems (IDS). The author proposes a new Host-Based Hybrid Intrusion Detection System. The Intrusion Detection Analyzer Module consists of two analyzers that work in a hybrid architecture: Anomaly Detection Analyzer and Misuse Detection Analyzer. This way, the Anomaly Detection Analyzer is trained with attack-free session data and normal behaviour...

In order to enhance the performance of a computer, most modern processors use superscalar architecture and raise the clock frequency. Superscalar architecture can execute more than one instruction per each cycle. The amount of instruction level parallelism will become more and more important when superscalar issue is increased. In some schemes [6, 14], instructions can be speculatively waked up. The more instructions are waked up, the more ILP is exploited, hence IPC is increased. We can adopt the speculative aspect to wakeup more instructions. But the ILP is still limited by the true data dependency. In this paper proposed the speculative wakeup logic with value prediction mechanism to overcome the data dependency that will exploit...

ICA and its variations are used extensively in BSS. Most of the algorithms that are used to separate speech or music signals utilize ICA in the time frequency domain. Here ICA is applied in the wavelet domain. Separation of signals is achieved by applying the ICA algorithm and shrinkage functions to the wavelet coefficients of the original mixtures. ICA alone can achieve reasonably good separation of artificially convolved sources; however, poor separation quality is experienced for real world convolutive mixtures. This work presents a novel post processing technique to deal with the cross talk problem. The post processor is applied to the signals separated by the ICA network. A super Gaussian form of the PDF is assumed for the dominant...

We introduce a new optimization theory for stencil-based applications which is centered both on a modi?cation of the well known owner-computes rule and on base but powerful properties oftoroidal spaces. The proposed optimization techniques provide notable results in di?erent computational aspects: from the reduction of communication overhead to the reduction of computation time, through the minimization of memory requirement without performance loss.

A collocation meshless method is developed for the numerical solution of Partial Differential Equations (PDEs) on the scattered point distribution. The meshless shape functions are constructed on a group of selected nodes (stencil) arbitrarily distributed in a local support domain by means of a polynomial interpolation. This shape function formulation possesses the Kronecker delta function property, and hence many numerical treatments are as simple as those of the Finite Element Method (FEM). Nearest neighbor algorithm is used for the support domain nodes collection and a search algorithm based on the Gauss-Jordan pivot method is applied to select a suitable stencil for the construction of the shape functions and their derivatives. This...

The continued need for size, weight and power reduction is driving electronics manufacturing towards embedding of components of Printed Circuit Boards (PCBs). Embedded components include thin film resistors placed in the build-up layers of PCBs. One challenge of embedding resistors is that applications require tighter resistance specification range as can be achieved by standard processes. Process capability analysis is widely used to assess how parts produced conform to the required specifications. In industrial practice, the normality assumption is often used to compute the traditional process capability indices (PCIs). However, the resistance values analyzed in this book are shown to be mainly characterized by non-normal...

The video compression techniques developed in the past deployed DCT (Discrete Cosine Transform) for removing spatial redundancies and MEC (Motion Estimation and Compensation) for removing temporal redundancies in the video stream. These techniques suffer from blocking artifacts and produces low quality compressed video when the bandwidth availability is low in case of simultaneous transmissions on the link. Many DWT based video compression techniques have been proposed, but, unfortunately no standard has been developed to deploy these techniques because either most of the techniques have not been implemented practically or desired results have not been obtained successfully. This study presents a new compression technique deploying DWT...

We introduce an object-oriented design of a physical store system for a relational database. The design and implementation of the physical store are in the style of C++ standard template library. They stress separation of memory allocation, iterators, container types, and the types of data in the store. The physical store system is part of the Know-It-All database project, under way at Concordia University. The contents of the physical store system are described using SQL data definition language. The main tasks of the physical store system are the bulk- loading of data, the support for the bulk creation of indexes, and data retrieval. The design hides the use of the secondary store. The problems with the existing physical stores are a...

Embedded electronic system design is currently faced with increasing levels of complexity, heterogeneity, and time-to-market demands. In order to cope with these pressures, abstraction and modularity are becoming cornerstones of today's design methodologies. However, if not accompanied by robust design frameworks and flows, they will not be successful. This book describes a number of frameworks and design flows which use a technique called Platform-based Design which addresses these concerns explicitly. This book discusses the emergence of Electronic System Level Design, the Metropolis and Metro II design frameworks, refinement verification and characterization techniques, as well as case studies in the areas of multimedia and...
