Experimental study of XRD, FTIR and TGA techniques in geopolymeric materials

The alkali activation of fly ashes produces a solid and compact material having similar properties to those of portland cement (PC) with characteristics of sustainable high value; these materials with high silica and aluminum are referred to as geopolymers. These new materials are a new generation of environmentally friendly cement, so it is very important to study their properties to validate their implementation; for which the application of new techniques currently being used. The work presented in this study focuses on establish the usual procedures of the techniques of X-ray diffraction (XRD), Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA) in its specific application to geopolymer base, or also called fly ash. Likewise, is determined the behavior of these materials for each of the above techniques.
Modelling and computation of optimal task assignment for cooperative control

In this paper, task assignment for cooperative control of multiple UAV's is studied. A model of linear programming is developed for multiple-tour assignment, both terminal and non-terminal tasks are included in the set of tasks. Although the problem is NP-hard, simulations show the possibility of real time computation for problems with small number of tasks. Examples of eleven tasks, including three terminal tasks, with four UAV's are shown. Matlab based software program is developed to numerically compute the optimal task assignment. Using a relatively slow PC, the computation takes about four seconds only. In addition to the linear programming model, a result on task assignment using partial information is proved. The result implies that the size of the linear programming is determined by the number of tasks, independent of the number of UAV's. For multiple-tour assignment with timing constraint but no terminal tasks, a scheduling process is added into the linear programming model so that tasks are serviced following a given sequence of time.
A perception system based on laser information for mobile robot topologic navigation

This paper presents a perception system for topological navigation using laser information. The localization system is based on the detection of landmarks (walls, doors and corners). A search algorithm based on Hough transform techniques for pattern recognition is used. The developed system allows the topologic localization and navigation of a mobile robot using landmarks. The resulting self-localization module has been integrated successfully in a more complicated navigation system. Various experimental results show the effectiveness of the presented algorithm.
Digital Watermarking On Micro Image Using Reversible Optical Reproduction

Digital watermarking is becoming increasingly important in a large number of applications such as copyright protection, content authentication, and document annotation. Reversible image watermarking, a kind of digital watermarking, is favored in fields sensitive to image quality like military and medical imaging. This paper studies the problem of achieving reversible visible image watermarking. I propose a lossless visible watermarking scheme that adaptively varies the watermark strength to be embedded in different areas of the host image, depending on the underlying image content and human visual system characteristics.
Architecture for web-based image processing

A computer systems architecture for processing medical images and other data coming over the Web is proposed. The architecture comprises a Java engine for communicating images over the Internet, storing data in local memory, doing floating point calculations, and a coprocessor MIMD parallel DSP for doing fine-grained operations found in video, graphics, and image processing applications. The local memory is shared between the Java engine and the parallel DSP. Data coming from the Web is stored in the local memory. This approach avoids the frequent movement of image data between a host processor's memory and an image processor's memory, found in many image processing systems. A low-power and high performance parallel DSP architecture containing lots of processors interconnected by a segmented hierarchical network has been developed. The instruction set of the 16-bit processor supports video, graphics, and image processing calculations. Two's complement arithmetic, saturation arithmetic, and packed instructions are supported. Higher data precision such as 32-bit and 64-bit can be achieved by cascading processors. A VLSI chip implementation of the architecture containing 64 processors organized in 16 clusters and interconnected by a statically programmable hierarchical bus is in progress. The buses are segmentable by programming switches on the bus. The instruction memory of each processor has sixteen 40-bit words. Data streaming through the processor is manipulated by the instructions. Multiple operations can be performed in a single cycle in a processor. A low-power handshake protocol is used for synchronization between the sender and the receiver of data. Temporary storage for data and filter coefficients is provided in each chip. A 256 by 16 memory unit is included in each of the 16 clusters. The memory unit can be used as a delay line, FIFO, lookup table or random access memory. The architecture is scalable with technology. Portable multimedia terminals like U.C. Berkeley's InfoPad can be developed using the proposed parallel DSP architecture, color display, pen interface, and wireless network communication for use in clinics, hospitals, homes, offices, and factories.
Study of the TCP/UDP fairness issue for the assured forwarding per hop behavior in differentiated services networks

The IETF Differentiated Services Working Group has standardized the assured forwarding (AF) per hop behavior (PHB). Studies of the AF PHB showed that there are a number of factors that affect fair bandwidth distribution for traffic flows with equal target rates. These factors cause unfair distribution of excess bandwidth in an over provisioned network as well as unfair degradation in an under provisioned network. One of the key factors identified is the effect of congestion non-responsive flows such as UDP when they share the same AF class with TCP flows. We investigate the effect of separating TCP and UDP flows into two AF classes of fair bandwidth distribution. The study shows that decoupling TCP and UDP flows in two AF classes controls distribution of bandwidth resources better than in the case when TCP and UDP flows share the same AF class. Moreover, an active queue management (AQM) technique that is used to realize the multiple levels of drop precedences required in the AF PHB becomes simpler for implementation. Isolation of TCP and UDP flows in router queues allows better control of the AF PHB, and therefore, better control of an overall end-to-end quality of AF service.
An Approach For Multidomain Query Optimization And Answering

In queries consists of multiple domains it is observed that general purpose search engines are unable to answer multidomain queries and out of which one of the domain is selected by specific search services but it is not possible to get an integrated framework.Qqueries which are answered by combining knowledge from two or more domains are Multidomain queries. And the objective is to present a multi-domain queries with an abstract formalism and to develop and optimizing a query system of several search services to choose best query plan to return relavant answers in ranked order. In this paper an approach is for handling multidomain queries on the web. It integrates different kind of services like web service, web search and combination of them. The google search and the web service of dapper is used to refine the results of query as more relevant results. It introduces the well defined model for expressing query results in ranking order. Here the query tends to find the results with cross domain joins to address the solution for optimized answering of multidomain queries. They gives the survey for multidomain query answering with answers as an optimized solution to obtain better search results using web services. The output is gained by chunking the whole query in several domain and then combining the whole result. The query which is chunked go for finding on each domain and then the result which is more relevant to all the domains in multidomain query are selected as an top N results. For getting the optimized and relevant results the sharpNLP tools are used as chunking and POS tagging . After that the best result can be selected. Query optimization and query answering both are done on multidomian query entered in web based system for search and the output is web service and google where web service, dapper go for specific entity selection like url, so that the search will be fast and relevant. The idea in this paper is to collect the best results from the best using web search and service and the relevance is maintained by ranking the results.

Multi-carrier CDMA system with parallel interference cancellation for multipath fading channels

The multi-carrier CDMA technique is attractive in a wireless communication system. It can support a high rate data transmission with a high spectral efficiency. The MC-CDMA (multi-carrier code division multiple access) receiver which employs a multiple access interference (MAI) canceller is proposed and analyzed. The receiver first demodulates the received signal to produce the initial data and the channel estimates. Based on these channel estimations, the cancellation scheme essentially creates the replicas of the MAI and removes them for the second improved data decision. Using theoretical analysis and simulation, the performance of MC-CDMA with parallel interference cancellation (PIC) is investigated according to the mean square error (MSE) of the channel estimation. The result shows the considerably large improvement in performance, which is attained by the interference cancellation technique. But if channel estimation is not performed accurately, then the effect of interference cancellation may be significantly decreased.
Transformational Planning of Reactive Behavior

Abstract : Reactive plans are plans that include steps for sensing the world and coping with the data so obtained. We investigate the application of Al planning techniques to plans of this sort in a simple simulated world. To achieve fast reaction times, we assume that the agent starts with a default reactive plan, while the planner attempts to improve it by applying plan transformations, thus searching through the space of transformed plans. When the planner has what it believes to be a better plan, it swaps the new plan into the agent's controller. The plans are written in a reactive language that allows for this kind of swapping. The language allows for concurrency, and hence, truly 'nonlinear' plans. The planner evaluates plans by projecting them, that is, generating scenarios for how execution might go. The resulting projections give estimates of plan values, but also provide clues to how the plan might be improved. These clues are unearthed by critics that go through the scenario sets, checking how the world state and the agent state evolved. The critics suggest plan transformations with associated estimates of how much they will improve the plan. Plan transformations must be able to edit code trees in such a way that the changes are orthogonal and reversible whenever possible. The system has been tested by comparing the performance of the agent with and without planning. Preliminary results allow us to conclude that the planner can be fast and directed enough to generate improved plans in a timely fashion, and that the controller can often cope with a sudden shift of plan.
Evaluating the Usability and Usefulness of an E-Learning Module for a Patient Clinical Information System at a Large Canadian Healthcare Organization

Supervisory Committee Dr. Andre Kushniruk Supervisor Dr. Elizabeth Borycki Departmental Member Alberta Health Services (AHS) has introduced e-learning for health professionals to expand their existing training, offer flexible web-based learning opportunities, and reduce training time and cost. This study is designed to evaluate the usability and usefulness of an e-learning module for a patient clinical information system scheduling application. A cost-effective framework for usability evaluation has been developed and conceptualized as part of this research. Low-Cost Rapid Usability Engineering (LCRUE), Cognitive Task Analysis (CTA), and Heuristic Evaluation (HE) criteria for web-based learning were adapted and combined with the Software Usability Measurement Inventory (SUMI) questionnaire. To evaluate the introduction of the e-learning application, usability was assessed in two groups of users: frontline users and informatics consultant users. The effectiveness of the LCRUE, CTA, and HE when combined with the SUMI was also investigated. Results showed that the frontline users are satisfied with the usability of the e-learning platform. Overall, the informatics consultant users are satisfied with the application, although they rated the application as poor in terms of efficiency and control. The results showed that many areas where usability was problematic are related to general interface usability (GIU), and instructional design and content, some of which might account for the poorly rated aspects of usability. The findings should be of interest to developers, designers, researchers, and usability practitioners involved in development of e-learning systems.

Semantic Aware Multi-Agent System Advantages

Internet changes the way people communicate with each other and also affects the business flow. Technology changes affect how people live and communicate with each other, but they themselves also transform and become more human like. The agent oriented programming and multi-agent systems are relatively new example technologies that manifest these changes in a multifacet way. The goal of this paper is to explore the possibilities one can obtain by combining multi agent systems with the emerging semantic web technologies. This powerful combination leads towards new types of complex system development. Using a case study example, together with a comparison with the traditional system design approach, the paper also discusess the possibilities of semantic agent platforms and their development and shows how developers can benefit from following the standards to agent development.
REQUIREMENTS TRACING USING INFORMATION RETRIEVAL

OF DISSERTATION Senthil Karthikeyan Sundaram The Graduate School University of Kentucky 2007 REQUIREMENTS TRACING USING INFORMATION RETRIEVAL ABSTRACT OF DISSERTATIONOF DISSERTATION A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the College of Engineering at the University of Kentucky By Senthil Karthikeyan Sundaram Lexington, Kentucky Director: Dr. Jane Huffman Hayes, Associate Professor of Computer Science Lexington, Kentucky 2007 Copyright c © Senthil Karthikeyan Sundaram 2007 ABSTRACT OF DISSERTATIONOF DISSERTATION REQUIREMENTS TRACING USING INFORMATION RETRIEVAL It is important to track how a requirement changes throughout the software lifecycle. Each requirement should be validated during and at the end of each phase of the software lifecycle. It is common to build traceability matrices to demonstrate that requirements are satisfied by the design. Traceability matrices are needed in various tasks in the software development process. Unfortunately, developers and designers do not always build traceability matrices or maintain traceability matrices to the proper level of detail. Therefore, traceability matrices are often built “after-the-fact. ” The generation of traceability matrices is a time consuming, error prone, and mundane process. Most of the times, the traceability matrices are built manually. Consider the case where an analyst is tasked to trace a high level requirement document to a lower level requirement specification. The analyst may have to look through M x N elements, where M and N are the number of high and low level requirements, respectively. There are not many tools available to assist the analysts in tracing unstructured textual artifacts and the very few tools that are available require enormous pre-processing. The prime objective of this work was to dynamically generate traceability links for unstructured textual artifacts using information retrieval (IR) methods. Given a user query and a document collection, IR methods identify all the documents that match the query. A closer observation of the requirements tracing process reveals the fact that it can be stated as a recursive IR problem. The main goals of this work were to solve the requirements traceability problem using IR methods and to improve the accuracy of the traceability links generated while best utilizing the analyst’s time. This work looked into adopting different IR methods and using user feedback to improve the traceability links generated. It also applied wrinkles such as filtering to the original IR methods. It also analyzed using a voting mechanism to select the traceability links identified by different IR methods. Finally, the IR methods were evaluated using six datasets. The results showed that automating requirements tracing process using IR methods helped save analyst’s time and generate good quality traceability matrices.
Relationship of value of teeth color with skin color in Makassar tribe

Objective: This study aim to determine the relationship between teeth color value and skin color value of the Makassar tribe. Material and Methods: This observational analytic research employs cross-sectional study and purposive sampling methods, with 73 samples; held in May 2012 in Bontoramba, Jeneponto district, South Sulawesi, Indonesia. It uses the Vita-Lumina shade guide for teeth color tests and Garnier FD344110.122. 007 for skin color tests. Results: The results show that the distribution of teeth colour value in respondents is mostly in the highest values (A1, B1, A2, B2 color) which were 71.2%, while the skin value is mostly in a dark skin color (78.1%). Data was analyzed by the chi-square test. It was found that teeth color value was not related to skin color value in the Makassar tribe (p>0.05). Conclusion: Skin color value was not an indicator in determining the teeth color in the Makassar tribe.
Aiding in the comprehension of testsuites

An integral part of test-driven software development is utilizing testcases to ensure the software’s quality. However, as testsuites grow larger, they tend to grow beyond control and are no longer easily comprehended. In this position paper, we propose to employ dynamic analysis and abstractions in reconstructing scenario diagrams from such testsuites. We discuss several challenges and suggest solutions to tackle these issues.
Self-Organization of Object Categories in a Cortical Artificial Model

Explaining the human capacity to construct mental categories is a central question in cognitive science, yet how reality is perceived and compartmentalized by our mind has puzzled philosophers since Aristotle. Today, categorization is believed to be a strategy humans have in common with many animals. In most species, individuals have the opportunity to directly experience only a tiny fraction of the entities, objects, features and events offered by their environments. By relying on categorization, organisms become able to determine which things in the world belong together or are alike in some way, therefore reacting in an appropriate manner, thanks to the previous experiences had with other instances of the same category. The purpose of this chapter is to investigate computational models that can simulate mechanisms underlying the ability to develop categories. We argue that a neural mechanism for detecting and coding recurrent coincidences in stimuli could be the key component in our brain’s ability to build the categories it uses to organize reality. The mathematical framework that has given the best interpretation so far on how signals with high levels of autocorrelation affect networks of neurons with local coincidence detection and coding abilities, is the one referred to as self-organization. Being categorization a phenomena appearing at so many different cognitive levels, and that is pervasive in so many different modalities, we doubt that it could rely upon a single mechanism. Moreover, we believe that humans unlike any other animal reshape their categories and build new ones, by virtue of the information provided to them by language as soon as they have developed the most rudimentary understanding of it. Nevertheless, we do not see reasons for posing that the pre-linguistic development of categories in infants should happen as a result of mechanisms different from those found in other species. Even if we are convinced that different mechanisms might contribute, the basic mechanism briefly discussed is one we consider to play a key role.
Meta-materials concepts in high-frequency applications

The electronics world has continued to push for reduction of physical size in terms of individual components and total package dimensions. In most cases, this size reduction has been accomplished without sacrificing quality or functionality. Conversely, the antenna structures from which many of these electronics packages will send or receive signals has not kept pace with the overall trend of reduction in physical size. Now, however, the application of meta-material concepts to high-frequency radiating structures and the substrates supporting these structures is enabling a reduction in the physical size of these elements. The size reduction is being accomplished without degradation of element performance; in some cases, it has enabled enhanced characteristics. An overview of these reduced-size structures is presented.
