An interactive visualization of the past using a situated simulation approach

This paper describes aspects of the development of an interactive installation for visualizing a 3D reconstruction of a historical church chapel in Kolding, Denmark. We focus on three aspects inherent to a mobile Augmented Reality development context; 1) A procedure for combating gyroscope drift on handheld devices, 2) achieving realistic lighting computation on a mobile platform at interactive frame-rates and 3) an approach to relocation within this applications situated location without position tracking. We present a solution to each of these three aspects. The development is targeted a specific application, but the presented solutions should be relevant to researchers and developers facing similar issues in other contexts. We furthermore present initial findings from everyday usage by visitors at the museum, and explore how these findings can be useful in connection with novel technology for facilitating information transfer to a museum audience. The installation is in active commercial use and is currently logging further user interactions via in-application logging for future investigations in line with this project.
Micromanagement in Merger : The case of Sunderby Hospital Merger

Purpose The purpose of this paper is to investigate and analyze the reasons as given by the Norrbotten County Council behind the Sunderby hospital merger. Background Mergers and Acquisitions have grown to become very popular as a way for achieving organizational development. This has been seen in both public and corporate sectors. Mergers did not become popular in the Swedish health care sector until the end of the 21th century, when the first merger took place many followed. In this case the authors investigate one of these hospital mergers. Method The authors have made a qualitative research. To gather data they contacted the authorities and interview politicians. The authorities provided them with public documents from their archive. The interviews were semi-structured with open-ended questions. Conclusion The authors of this thesis have found that the Sunderby hospital merger was supported by academic literature. The reasons stated by the Norbotten County Council (NCC) for doing the merger, were consistent with theories about mergers found in academic research. The authors have also provided their non-supported beliefs under the Discussion section, as well as recommendations for further studies.
Optimized Fuzzy Semi-active Control of Flow-induced Vibration of Hydraulic Arch Sluice

Improving hydraulic boundary condition and optimizing arch sluice structure are very important measures to reduce the flow-induced vibration of hydraulic arch sluice, but these measures, which can only be taken before construction, are not enough for reduction of the vibration. Employing structural control method is a further approach to this problem. This approach is significant for vibration mitigation of already existing arch sluice. The optimized fuzzy control strategy based on genetic algorithm (GA) takes advantage of powerful optimization capability of GA and avoids the weakness of ordinary fuzzy logic control (FLC) designing in which inference rules and membership functions of FLC are chosen by expert experiences. In this method, a multi-population GA with real-integer-mixed encoding was put forward. Based on this method, optimized fuzzy semi-active control strategy was proposed to reduce the vibration of certain arch sluice installed with magnetorheological (MR) dampers. The simulated result shows that MR dampers can diminish flow-induced vibration of the arch sluice effectively under this strategy and the proposed method is much better than the ordinary FLC
Representing Defaults as Sentences with Reduced Priority

We distinguish between two ways of thinking about defaults. The rst way, in which defaults augment known premises by`strengthening' the underlying logic, is the traditional approach taken by most existing formalisms. In the second way, defaults are represented in the set of premises, but obtain their default status by having a reduced priority relative to the known premises. In this paper we: 1. Compare and contrast the approaches. We argue that the second approach makes for simpler representation of defaults and their interactions. 2. Describe a syntax and semantics for the second, less well-known approach; we introduce the notion of ordered theory presentation (OTP) to represent theories with defaults. 3. Show how ordered theory presentations can represent familiar examples of interacting defaults in an intuitively clear and simple way; we give the Tweety example and the Yale Shooting example. We also show that the OTP framework is particularly well suited to inheritance examples. 4. Show formal properties of OTPs, in particular cu-mulativity, and suggest connections with circumscrip-tion. 5. Show how OTPs may be used to model belief revision and compare the result with the standard theory.
Spatial Estimation of Housing Prices and Locational Rents

This work stems from the widely accepted hypothesis that housing price is determined by two types of characteristic: structural and locational. Under this hypothesis, a methodology is presented for the spatial estimation of housing prices and locational rents: the Iterative Residual Kriging (IRK) method. The methodological aspects are complemented by the presentation of an application of this methodology to the case of housing in Granada, Spain.
Particle Acceleration in Astrophysical Shear Flows

We consider the acceleration of particles due to a velocity shear in relativistic astrophysical flows. The basic physical picture and the formation of power law momentum spectra is discussed for a non-relativistic velocity field using a microscopic approach. We identify possible sites for shear acceleration in relativistic astrophysical jets and analyze their associated acceleration timescales. It is shown in particular that for a mean scattering time τ scaling with the gyro-radius, the acceleration timescale for gradual shear scales in the same manner as the synchrotron cooling timescale so that losses may no longer be able to stop the acceleration once it has started to work efficiently. Finally, the possible role of shear acceleration is discussed with reference to the relativistic jet in the quasar 3C 273.
A Feline Case of Hepatic Neuroendocrine Carcinoma with Gastrin Immunoreactivity

ABSTRACT A 5-year-old castrated Japanese domestic cat was presented with persistent vomiting. Ultrasound examinations revealed many masses only in the liver, and the fine needle aspiration was performed. Cytologically, polygonal or oval shaped tumor cells forming rosette and cord-like patterns were demonstrated, and then, the hepatic lesions were diagnosed as neuroendocrine carcinoma tentatively. The cat died one month after admission and was necropsied. Histopathologically, the tumor cells of the hepatic mass were arranged in typical rosette and cord-like structures. They were considerably uniform in size with hyperchromatic round nuclei and eosinophilic cytoplasm. Most of tumor cells were immunopositive for chromogranin A, and some were positive for gastrin. The findings indicate the possibility that the present case was a gastrin-producing neuroendocrine carcinoma.
A multi-attribute routing protocol for opportunistic network environments

In opportunistic networks, nodes hold packets in permanent storage and make independent routing decisions on sporadically emerging links. This helps to achieve connectivity even if an end-to-end contemporaneous path does not exist between a pair of nodes. Next-hop decision is generally dependent on future probability of encounters with a destination node while other constraints on nodes' resources are ignored. We argue, in this paper that considering multiple parameters related to destination dependent and independent characteristics of a node, while determining its next-hop fitness, can help achieve better performance in resource-stringent opportunistic network environments. Our proposed routing protocol, MARS, not only gets itself cognizant of mobility patterns present within the network but also combines these mobility patterns with other stochastic information about nodes' characteristics. With the help of simulations, we show that MARS is able to achieve high delivery rates and comparable end-to-end latency with well-known routing protocols while maintaining its overhead to a significantly low limit.
Revision of CTL Models 1 Author ( s ) :

Model checking is one of the most robust techniques in automated system verification. But, although this technique can handle complex verifications, model checking tools usually do not give any information on how to repair inconsistent system models. In this paper, we show that approaches developed for CTL model update cannot deal with all kinds of model changes. We introduce the concept of CTL model revision: an approach based on belief revision to handle system inconsistency in a static context. We relate our proposal to classical works in belief revision and give an algorithm sketch.
1 Information Strategy in Adhocratic Businesses Dr

An investigation has been carried out that examines the relationship between an organisation's structure and the information systems that support its operations. Twenty five business units in an international bank were studied in terms of organisational structure and information systems. This paper examines in detail the eight business units that were classified as adhocracies. End user computing was commonly used as the strategy for effectively using information technology in these units. A hypothesis derived from the work of Mintzberg was tested and found to be of limited usefulness. 2 1. INTRODUCTION The specific need to carry out strategic planning for the information systems (IS) and information technology (IT) infrastructure of the organisation became obvious in larger organisations as budgets increased and the impacts, both inside and outside The need increased for many when it appeared that competitors were able to achieve competitive advantage through made even more pressing through the decentralisation and distribution of computer power that enabled user managers to dramatically change the ways in which their business activities were carried out (Lee, 1988; Lederer and Mendelow, 1988). Initial approaches to the task of carrying out information systems strategic planning (ISSP) were simple models and frameworks that helped understanding and showed opportunities but did not lead to an implementable plan (McLean and Since then many methodologies have been developed that will guide the user to an IT development portfolio (Earl, 1989; Lederer and Sethi, 1988). Most methodologies have been pragmatically developed and investigate three areas: business needs, an enhancement path for existing systems, and technology-driven opportunities. A common weakness is the technique for evaluation of alternative proposals created in the investigations. The need to ensure that the development plan fits with the organisation has also received little attention in the established methodologies (McFarlan, 1990). ISSP remains complex, expensive and uncertain. Organisations that have carried out ISSP are not assured of success in developing applications of IT that will achieve competitive advantage (Earl et al., 1988). Conversely, organisations may develop successful applications without engaging in ISSP. Our aim is to provide IS 3 strategic planners with additional tools to enable them to carry out shorter, quicker strategic assessments and to enable them to evaluate more critically some of the proposals raised in the strategic planning process. In particular, planners should be able to evaluate the alignment of a potential application with the organisation's competitive strategy, and its compatibility with the …
education programme Using modern IT tools to assess the awareness of MDs on radiation issues and plan a continuous

INTRODUCTION The triumvirate mission for almost any academic health institution includes patient care, research and medical education. Education for health professionals can be divided into three main sections: basic preparation, continuing education to advance knowledge and continuing education to remain competent. Basic preparation occurs in schools, colleges and universities , advancing knowledge may be through participation in conferences and graduate educational programmes and remaining competent is an attitude of lifelong learning that can occur anywhere and at any time. Developments in Information Technologies and Communications (ICT) can be applied to enhance the whole educational process of medical doctors (MDs) and health professionals in general. Applications include access to libraries, databases and other resources by means of the Internet, the production and availability of high quality multi-media educational materials, simulation and effective laboratory experiences, extended collaborations and the management of educational activities and teleteaching. It makes it possible for medical educational programmes and continuing education activities to expand the scope and quality of teaching by utilizing highly qualified and experienced faculty staff and resources that might be located anywhere in the world. Radiation is strongly involved in a number of common medical tests especially in Radiology (R) and Nuclear Medicine (NM). Medical knowledge about issues of ionizing radiation, especially at fundamental level, is therefore mandatory in clinical practice. University-level educational programmes concerning medical physics are taught, however, early in the very first years of their medical studies. As a result, it is expected that medical doctors' (MDs) famil-iarization with ionizing radiation will vary when they reach the point of clinical work. For all these reasons we thought that radiation issues would fit nicely as an example in assessing the awareness of MDs and health professionals in general, in the specific field of knowledge. This type of assessment may then be further exploited to attempt a better planning of the continuous education process. One of the key issues involved in the above assessment procedure, however, is how to make use of available technology in order to conduct the assessment as efficiently and as effectively as possible. In previous work, we devised a sample manual questionnaire aimed at retrieving information regarding the status of radiation knowledge of MDs [1]. We then investigated the feasibility of applying a robust methodology Using modern IT tools to assess the awareness of MDs on radiation issues and plan a continuous education programme Radiation is significantly involved in …
Supporting revisitation with contextual suggestions

Web browsers provide only little support for users to revisit pages that they do not visit very often. We developed a browser toolbar that reminds users of visited pages related to the page that they currently viewing. The recommendation method combines ranking with propagation methods. A user evaluation shows that on average 22.7% of the revisits were triggered by the toolbar, a considerable change on the participants' revisitation routines. In this paper we discuss the value of the recommendations and the implications derived from the evaluation.
MRI, 1H-MRS, and functional MRI during and after prolonged nonconvulsive seizure activity

&NA; Article abstract— Background Various structural and functional changes, such as focal edema, blood flow, and metabolism, occur in the cerebral cortex after focal status epilepticus. These changes can be assessed noninvasively by means of MRI techniques, such as fluid-attenuated inversion recovery (FLAIR), EEG-triggered functional MRI (EEG-fMRI), and proton MR spectroscopy (MRS). Methods The authors report on a 40-year-old patient with nonlesional partial epilepsy in the left posterior quadrant in whom these MRI techniques were applied in an active seizure focus and repeated during a follow-up of 1 year. Results FLAIR imaging taken at the time of status epilepticus showed a signal hyperintensity in the occipital region. 1H-MRS of this cortical region showed elevated lactate, decreased N-acetylaspartate (NAA), and elevated choline (Cho). In the same region, EEG-fMRI revealed an area of signal enhancement. After seizure control, recovery of lactate and Cho was observed, whereas the NAA level remained reduced. The structural abnormality demonstrated on FLAIR disappeared within 3 months. Conclusions Repetitive MRI with sensitive sequences during clinically critical periods may disclose the structural correlate in a previously nonlesional epilepsy case. Corresponding to the clinical evolution, reversible and irreversible focally abnormal metabolism can be determined with 1H-MRS, reflecting both increased neuronal activity and neuronal damage.
Data-driven trajectory smoothing

Motivated by the increasing availability of large collections of noisy GPS traces, we present a new data-driven framework for smoothing trajectory data. The framework, which can be viewed of as a generalization of the classical moving average technique, naturally leads to efficient algorithms for various smoothing objectives. We analyze an algorithm based on this framework and provide connections to previous smoothing techniques. We implement a variation of the algorithm to smooth an entire collection of trajectories and show that it performs well on both synthetic data and massive collections of GPS traces.
Neo-piagetian Forms of Reasoning in Software Development Process Construction

ICT students continue to struggle in their development of fundamental programming skills and software development processes. Crucial to successful mastery is the development of discipline specific cognitive and metacognitive skills, including self-regulation. We can assist our students in the process of reflection and self-regulation by identifying and articulating successful self-regulated learning strategies for specific discipline contexts. However, in order to do so, we must develop an understanding of those discipline specific strategies that can be successful and readily adopted by students, and ways of understanding and articulating successful mental models. In this paper, we explore a Neo-Piagetian analysis of students' reflections upon their software development processes, enabling us to identify mental models for software development. We adopt a case study approach, identifying key examples of pre-operational behaviours that rely upon self-regulated learning strategies in place of articulated mental models, through to formal operational behaviours exhibiting complex, multi-relationship models of software development and design activities. Our study provides support for pedagogy for sharing of mental models and strategies amongst students, and guiding students by explicitly modelling the software development process.
Calcium Determination in EDTA Treated Plasma by Colorimetric Method and Microplate Reading Format

Background:: Calcium has different functions in metabolic processes and increase or decrease of calcium level in blood may lead to different disorders. Therefore, measurement of calcium level in blood is an important clinical issue. It is not possible to measure calcium in plasma samples which contain calcium chelators and we need serum samples to do so. This research aims to investigate the simple and direct colorimetric method for calcium measuring in EDTA treated plasma. Materials and Methods:: In this experimental study, through adding a patented solution to EDTA treated plasma, calcium ions are released from calcium chelators and then reacted with ortho cresolphthalein complexone (o-CPC) as a coloring reagent and finally product of calcium reaction is measured using microplate reading format. The details of methodology are patented on 29.04. 2012 in State Organization for Registration of Deeds and Properties with registration number of 74804, and are the exclusive property for the owners. Sensitivity, precision, accuracy and the correlation of plasma calcium with serum calcium level were investigated. Results:: Sensitivity of this method was 0.4 mg/dL. Coefficient of variation for intra assays and inter assay were less than 5% and 6% respectively. According to recovery and parallelism tests, ratio and recovery percent ranged from 90 to 110% and correlation coefficient in compare with determination of calcium in serum by the same reagent was 0.92. Conclusion:: This method is capable of measuring calcium in EDTA treated plasma and in addition, it has the required sensitivity, precision and accuracy for common clinical tests.
Human telomeric position effect is determined by chromosomal context and telomeric chromatin integrity

We investigated the influence of telomere proximity and composition on the expression of an EGFP reporter gene in human cells. In transient transfection assays, telomeric DNA does not repress EGFP but rather slightly increases its expression. In contrast, in stable cell lines, the same reporter construct is repressed when inserted at a subtelomeric location. The telomeric repression is transiently alleviated by increasing the dosage of the TTAGGG repeat factor 1 (TRF1). Upon a prolongated treatment with trichostatin A, the derepression of the subtelomeric reporter gene correlates with the delocalization of HP1α and HP1β. In contrast, treating the cells with 5 azacytidin, a demethylating agent, or with sirtinol, an inhibitor of the Sir2 family of deacetylase, has no apparent effect on telomeric repression. Overall, position effects at human chromosome ends are dependent on a specific higher‐order organization of the telomeric chromatin. The possible involvement of HP1 isoforms is discussed.
Assuring Academic Standards by Building Trust in Academics Judgements: Development and Implementation of an Institution-Wide Framework

This paper provides an overview of a two year project that is developing and implementing an institution-wide framework to support comprehensive quality assurance of assessment standards. Progress is here reported at the one year mark. The abstract reports on the background to, and significance of, the work. It then describes each of the components of the model and how they collectively allow the institution, and all associated stakeholders, to have greater trust in the judgements academics make of students' work. The paper makes clear that the framework can be applied in any institution.
Feature grouping from spatially constrained multiplicative interaction

We present a feature learning model that learns to encode relationships between images. The model is defined as a Gated Boltzmann Machine, which is constrained such that hidden units that are nearby in space can gate each other's connections. We show how frequency/orientation "columns" as well as topographic filter maps follow naturally from training the model on image pairs. The model also helps explain why square-pooling models yield feature groups with similar grouping properties. Experimental results on synthetic image transformations show that spatially constrained gating is an effective way to reduce the number of parameters and thereby to regularize a transformation-learning model.
