An optimised algorithm for velocity estimation method for motor drives

Traditionally two different algorithms are used for the estimation of angular velocity with an incremental encoder. At steady state, both of them ensure good performances only in a restricted range of velocity. In the paper an innovative hybrid algorithm specifically conceived for digital control system is proposed. The algorithm is quite easy to implement and guarantees a reduced relative error in a wide range of velocity variation. The algorithm is analyzed with an analytical approach and the results are confirmed by numerical simulations. Since in dynamic conditions the error in the measurement of the angular velocity with an encoder is strictly connected with the observation time, a correct method for the dimensioning of the observation time is discussed. The method can be combined with the preceding algorithm to obtain adaptive capabilities.
Classification of ECG arrhythmias using multi-resolution analysis and neural networks

Automatic detection and classification of cardiac arrhythmias is important for diagnosis of cardiac abnormalities. We propose a method to accurately classify ECG arrhythmias through a combination of wavelets and artificial neural networks (ANN). The ability of the wavelet transform to decompose signal at various resolutions allows accurate extraction/detection of features from non-stationary signals like ECG. A set of discrete wavelet transform (DWT) coefficients, which contain the maximum information about the arrhythmia, is selected from the wavelet decomposition. These coefficients are fed to the back-propagation neural network which classifies the arrhythmias. The proposed method is capable of distinguishing the normal sinus rhythm and 12 different arrhythmias and is robust against noise. The overall accuracy of classification of the proposed approach is 96.77%.
Comparative Analysis of Face Recognition Methodologies and Techniques

In the field of computer sciences such as graphics and also analyzing the image and its processing, face recognition is the most prominent problem due to the comprehensive variation of faces and the complexity of noises and image backgrounds. The purpose and working of this system is that it identifies the face of a person from the real time video and verifies the person from the images store in the database. This paper provides a review of the methodologies and techniques used for face detection and recognition. Firstly a brief introduction of Facial Recognition is given then the review of the face recognition’s working which has been done until now, is briefly introduced. Then the next sections covered the approaches, methodologies, techniques and their comparison. Holistic, Feature based and Hybrid approaches are basically used for face recognition methodologies. Eigen Faces, Fisher Faces and LBP methodologies were introduced for recognition purpose. Eigen Faces is most frequently used because of its efficiencies. To observe the efficient techniques of facial recognition, there are many scenarios to measure its performance which are based on real time.
Guidelines for maternal mortality epidemiological surveillance.

Maternal mortality is an important public health problem that affects the individual the family and the society. Surveillance is an important part of any program that is aimed at reducing maternal mortality. It provides vital information to design interventions to impact maternal health. This booklet presents updated Guidelines for Maternal Mortality Epidemiological Surveillance (MMES). The updated guidelines describe several methods to identify and investigate maternal deaths describe ways that these data can be analyzed to produce useful information and suggest some actions that may help reduce maternal mortality. The booklet was the product of the meeting among the Pan American Health Organization (PAHO) WHO Collaborating Center in Perinatal Care at the Center for Disease Control and Prevention and MotherCare in Atlanta Georgia (US) on April 18-19 1995. The resources used in compiling the booklet include data collected by the STAG Evaluation of the Progress on the Regional Plan site visits to countries reports and comments made by participants at the 1995 PAHO Maternal Mortality Epidemiological Surveillance Guidelines meetings and both published and unpublished literature. Explicitly highlighted in the updated Guidelines are the experiences that various countries had in developing MMES meeting implementation goals and overcoming problems in operating the system.
Where Is “Place” in Aging in Place? Transnational Issues for the Danish State and Its Retirement Migrants Abroad

The aim of this article is to contribute a transnational perspective to the field of environmental gerontology and the concept of aging in place. Seniors from the northern hemisphere, among them Danish citizens, are increasingly adapting to transnational lives as they move to warmer climates. This article builds on a qualitative study among Danish retirement migrants regarding their experiences with the need for care or support while living abroad. Denmark is a welfare state with a long history of public nursing homes and in-home care for frail elderly persons. This system of governance is influenced by universalism, aiming at equality in terms of access to health services and care. However, these welfare provisions seem to be deeply embedded in methodological nationalism, since only citizens with residence within the borders of Denmark have the right to live in public nursing homes or receive in-home help. It is argued that we should consider public solutions to the problems faced by frail Danish citizens in transnational settings, enhancing their opportunities to live abroad.
The CMS L1 Trigger emulation software

The CMS L1 Trigger processes the muon and calorimeter detector data using a complex system of custom hardware processors. A bit-level emulation of the trigger data processing has been developed. This is used to validate and monitor the trigger hardware, to simulate the trigger response in monte-carlo data, and for some components, to seed higher-level triggers. The multiple-use cases are managed using a modular design, implemented within the modular CMS offline software framework. The requirements, design and performance of the emulators are described, as well as the iterative process required to bring the emulators and hardware into agreement.
Framework for planning a successful retirement: Marie Wheatley considers how best to make the transition from being an active member of a structured workforce to getting the most out of retirement

Ideas about retirement have changed. Just a few decades ago there was a cut off date when workers had an expected date of retirement, but today this decision is generally left up to the individual. Retirement affects people in different ways and there is some recognition that they may experience similiar stages to those of bereavement including loss, denial and anger, which require adjustment. This article looks at how to make decisions about planning retirement and follows the three stages of preparation suggested by Daniel and Beer (2011), whose framework is aimed at those reaching this stages of their lives.
Providing Freshmen with a Good “Starting-Block”: Two Brief Social-Psychological Interventions to Promote Early Adjustment to the First Year at University

Grounded in social-psychological literature, this experimental study assessed the effects of two so-called “wise” interventions implemented in a student study program. The interventions took place during the very first week at university, a presumed pivotal phase of transition. A group of 375 freshmen in psychology were randomly assigned to three conditions: control, social belonging, and self-affirmation. Following the intervention, students in the social-belonging condition expressed less social apprehension, a higher social integration, and a stronger intention to persist one month later than the other participants. They also relied more on peers as a source of support when confronted with a study task. Students in the self-affirmation condition felt more self-affirmed at the end of the intervention but didn’t benefit from other lasting effects. The results suggest that some well-timed and well-targeted “wise” interventions could provide lasting positive consequences for student adjustment. The respective merits of social-belonging and self-affirmation interventions are also discussed.

Secondary school mathematics and science matters: academic performance for secondary students transitioning into university allied health and science courses

The literature strongly indicates that secondary school performance is highly predictive of university performance. Moreover, scholars have identified that successful performance in university mathematics and science courses depends on the level of mathematics studied in secondary school. This paper investigated the extent to which particular mathematics and science courses (e.g. Stage 2; intermediate and Stage 3; advanced) completed at secondary school affected the Grade Point Average (GPA) of 521 first-year Health Science, Physiotherapy and Nursing students within an Australian university. Based upon a statistical analysis of student performance (secondary Australian Tertiary Admissions Ranking (ATAR) score and first-year university GPA), the authors used a general linear model to investigate which secondary science and mathematics courses were associated with higher first-year university GPA. The key findings of this quantitative research project were that: the level of secondary mathematics studied, studying physical science courses at secondary school, and the completion of both advanced level mathematics and science courses were all associated with higher first-year university GPA.
An Approach to Adaptive Network

This paper describes the concept of an adaptive network, that is, a network environment that can rapidly and autonomously adapt its behavior according to network conditions and traffic status. The user interface of the adaptive network can access any resource in the network as a memory-mapped I/O device, as if it were attached to the local bus of the user’s PC. This network concept has several benefits. From the application development viewpoint, no network related programming is required, and applications do not have to be modified even if the network topologies and protocols are changed. Network maintenance and upgrading can be done anytime without having to worry about the application users, because the network itself is concealed from the applications. In addition, the reconfigurable hardware technology functions as an autonomous network control through the use of a lower-layer protocol. We developed a testbed that makes heterogeneous resources available to users and used it to demonstrate the feasibility of our concept by implementing and running some applications over it. key words: computer network, distributed environment, effortless networking, resource abstraction, quality of service

Visualization in the neurosciences: Addressing problems in research, teaching and clinical practice

The use of visualization in five neuroscience projects is discussed. The issue of how structural models can be best manipulated to gain insight into nervous system function is addressed. Visualization projects that take up this issue from three different user perspectives (research, student, and clinician) are described. The first two projects, focus on the molecular level, particularly mechanisms of process and control within neuronal systems. The next two relate functional subsystems to gross morphology and neuroanatomical pathways in educational applications. The final project describes a long-term effort underway to develop a national resource of images related by function. These projects, when taken together, exemplify current trends and approaches in this area. Several technical and conceptual issues that extend beyond these projects are also discussed. These include delivery platforms, integration paths, the development of standards for image acquisition and representation, and use in routine medical practice. <<ETX>>

Visualization of Tree-Structured Data Through a Multi Touch User Interface

VISUALIZATION OF TREE-STRUCTURED DATA THROUGH A MULTI-TOUCH USER INTERFACE by David Andrews This writing project examines different types of visualizations for tree-structured data sets. Visualizations discussed include link-node diagrams and treemap diagrams. Also discussed is recent innovations with regards to distinguishing multi touch from single touch technology. I explore the requirements needed to build a multi touch table top surface, and describe the process of building one. I then describe my proposed method of visualizing tree-structured data and how it can be implemented using Core Animation technology. I also propose a means of interacting with the data through a multi touch interface, and discuss which gestures can be used to navigate the visualization display.
Essentials of Geographic Information Systems

Essentials of Geographic Information Systems integrates key concepts behind the technology with practical concerns and real-world applications. Recognizing that many potential GIS users are non-specialists or may only need a few maps, this book is designed to be accessible, pragmatic and concise. Essentials of Geographic Information Systems also illustrates how GIS is used to ask questions, inform choices and guide policy. From the melting of the polar ice caps to privacy issues associated with mapping, this book provides a gentle, yet substantive, introduction to the use and application of digital maps, mapping and GIS.Maps are everywhere - on the internet, in your car and even on your mobile phone. Moreover, maps of the 21st century are not just paper diagrams folded like an accordion. Maps today are colorful, searchable, interactive and shared. This transformation of the static map into dynamic and interactive multimedia reflects the integration of technological innovation and vast amounts of geographic data. The key technology behind this integration, and subsequently the maps of the 21st century, is geographic information systems or GIS.In today's world, learning involves knowing how and where to search for information. In some respects, knowing where to look for answers and information is arguably just as important as the knowledge itself. Because the authors designed Essentials of GIS to be concise, focused and directed, readers are encouraged to search for supplementary information and to follow-up on specific topics of interest on their own when necessary. This text provides the foundations for learning GIS, but readers are encouraged to construct their own individual frameworks of GIS knowledge. The benefits of this approach are two-fold. First, it promotes active learning through re/search. Second, it facilitates flexible and selective learning, i.e., what is learned is a function of individual needs and interest.Since GIS and related geospatial and navigation technology change so rapidly, a flexible and dynamic text is necessary in order to stay current and relevant. Though essential concepts in GIS tend to remain constant, the situations, applications and examples of GIS are fluid and dynamic. The Flat World model of publishing with the MIYO (Make It Your Own) customization platform is especially relevant for a text that deals with information technology. The authors can keep the text updated easily, and you, the instructor, can add content on the technology that you find timely and relevant to the book with a few clicks on the mouse.Though this book is intended for use in introductory GIS courses, Essentials of Geographic Information Systems will also appeal to the large number of certificate, professional, extension and online programs in GIS that are available today.

A bandwidth scheduling method for efficient resource allocation in ATM networks

In this paper we address the problem of call admission and resource reservation control in ATM networks, where customers can book their connections in advance. This is very likely to be a realistic situation for services where customers order a connection to be established some time later. The proposed framework can be used for the admission and resource reservation control for leased line services or the establishment of virtual private networks (VPN), but also for services like video conferencing and video broadcasting. Point-to-point as well as point-to-multipoint connections are considered. We present a detailed mathematical model. Different solution techniques are proposed and their performance compared. A resource reservation and allocation planning tool is being developed. We will show by simulations that one can gain significant benefit from using bandwidth scheduling.
Age-friendly care

It is not news that older people are the largest users of most health-care services. People over 65�years occupy almost two thirds of general and acute hospital beds and are more likely to visit their general practice than younger adults. With the exception of a few specialist areas, nurses will regularly come into contact with older people.
Operator-adapted finite element wavelets : theory and applications to a posteriori error estimation and adaptive computational modeling

We propose a simple and unified approach for a posteriori error estimation and adaptive mesh refinement in finite element analysis using multiresolution signal processing principles. Given a sequence of nested discretizations of a domain we begin by constructing approximation spaces at each level of discretization spanned by conforming finite element interpolation functions. The solution to the virtual work equation can then be expressed as a telescopic sum consisting of the solution on the coarsest mesh along with a sequence of error terms denoted as two-level errors. These error terms are the projections of the solution onto complementary spaces that are scale-orthogonal with respect to the inner product induced by the weak-form of the governing differential operator. The problem of generating a compact, yet accurate representation of the solution then reduces to that of generating a compact, yet accurate representation of each of these error components. This problem is solved in three steps: (a) we first efficiently construct a set of scale-orthogonal wavelets that form a Riesz stable basis (in the energy-norm) for the complementary spaces; (b) we then efficiently estimate the contribution of each wavelet to the two-level error and finally (c) we select a subset of the wavelets at each level to preserve and solve exactly for the corresponding coefficients. Our approach has several advantages over a posteriori error estimation and adaptive refinement techniques in vogue in finite element analysis. First, in contrast to the true error, the two-level errors can be estimated very accurately even on coarse meshes. Second, mesh refinement is carried out by the addition of wavelets rather than element subdivision. This implies that the technique does not have to directly deal with the handling of irregular vertices. Third, the error estimation and adaptive refinement steps use the same basis. Therefore, the estimates accurately predict how much the error will reduce upon mesh refinement. Finally, the proposed approach naturally and easily accomodates error estimation and adaptive refinement based on both the energy norm as well any bounded linear functional of interest (i.e., goal-oriented error estimation and adaptivity). We demonstrate the application of our approach to the adaptive solution of second and fourthorder problems such as heat transfer, linear elasticity and deformation of thin plates.

Correlation between the Her-2/neu Status as Determined by Immunohistochemical Analysis and the Serum Her-2/neu Concentration as Determined by the Use of ADVIA Cencaur® Automated Immunoassay in Breast Cancer Patients

domain of the Her-2/neu tyrosine kinase to serum. We evaluated the correlation between the Her-2/neu status as determined by immunohistochemical analysis (IHC) and the serum Her-2/neu concentration in a population of Korean women with breast cancer. Methods: Serum Her-2/neu levels were examined from 254 female patients with primary breast cancer and 38 patients with metastatic breast cancer. Serum Her-2/neu levels were measured by the use of a chemiluminescence immunoassay (ADVIA centaur system) during the preoperative period. The level of Her-2/neu in all of the breast cancer tissue samples was determined by IHC, and samples with an IHC grade +2 were subject to fluorescence in situ (FISH). When tissue samples exhibited IHC grade +3 or showed amplification of Her-2/neu as determined by FISH analysis, Her-2/neu was considered overexpressed. The cut-off value for serum Her2/neu level was 10.2 ng/mL. Results: The mean serum Her-2/neu level was 10.1 ng/mL in primary breast cancer samples. The serum Her-2/neu concentration significantly correlated with expression of Her2/neu as determined by tissue IHC analysis (grade 1/3, 9.33 ±1.7 ng/mL; grade 2/3, 8.89±1.6 ng/mL; grade 3/3, 12.37 ±4.0 ng/mL, p<0.001). Increased serum HER-2/neu levels were associated with the lymph node status (p=0.003) and hormone unresponsiveness (p<0.001), tumor size (p<0.01) and age group (p<0.001). In metastatic breast cancer samples, the mean serum Her-2/neu level was 13.6 ng/mL. Elevated serum Her-2/neu levels were seen in 71.7% of metastatic breast cancer samples. The serum Her-2/neu level correlated with expression of Her-2/neu in metastatic tissue as determined by IHC analysis (p<0.001) rather than with the Her-2/neu status of the primary breast cancer (p=0.16) Conclusion: Serum Her-2/neu appears to be correlate with tissue Her-2/neu expression in primary and metastatic breast cancer where Her-2/neu is overexpressed. Further studies to determine levels of serum Her-2/neu are required to determine cuttoff values and the clinical application of the finding for breast cancer patients in Korea.
