Presentation and evaluation of gated-SPECT myocardial perfusion images

ii This master thesis project was performed in collaboration with [Karolinska university hospital-Thorax] Supervisor at [Karolinska hospital]: Dianna Bone Abstract Single photon emission tomography (SPECT) data from myocardial perfusion imaging (MPI) are normally displayed as a set of three slices orthogonal to the left ventricular (LV) long axis for both ECG-gated (GSPECT) and non-gated SPECT studies. The total number of slices presented for assessment depends on the size of the heart, but is typically in excess of 30. A requirement for data presentation is that images should be orientated about the LV axis; therefore, a set of radial slice would fulfill this need. Radial slices are parallel to the LV long axis and arranged diametrically. They could provide a suitable alternative to standard orthogonal slices, with the advantage of requiring far fewer slices to adequately represent the data. In this study a semi-automatic method was developed for displaying MPI SPECT data as a set of radial slices orientated about the LV axis, with the aim of reducing the number of slices viewed, without loss of information and independent on the size of the heart. Input volume data consisted of standard short axis slices orientated perpendicular to the LV axis chosen at the time of reconstruction. The true LV axis was determined by first determining the boundary on a central long axis slice, the axis being in the direction of the y-axis in the matrix. The skeleton of the myocardium were found and the true LV axis determined for that slice. The angle of this axis with respect to the y-axis was calculated. The process was repeated for an orthogonal long axis slice. The input volume was then rotated by the angles calculated. Radial slices generated for presentation were integrated over a sector equivalent to the imaging resolution (1.2 cm); assuming the diameter of the heart is about 8cm then non-gated data could be represented by 20 radial slices integrated over an 18 degree section. Gated information could be represented with four slices spaced at 45 intervals, integrated over a 30 degree sector.
EVALUATION OF GROUNDWATER QUALITY OF BULANDSHAHR CITY

The study is aimed at assessing the water quality index for drinking purposes of ground water of Bulandshahr city, U.P. Ground water quality has been determined by collecting 15 samples from different parts of Bulandshahr city. For calculating parameters such as pH, alkalinity, Total Hardness, TDS, Conductivity, Chloride, were considered No sample was found as excellent for drinking, although 1 sample out of all was found to be of good quality for drinking. More samples were declared poor for drinking purposes and 31.81 % samples were very poor for drinking purposes. This unsuitability of water quality of these samples is attributed to two factors i.e. large amount of waste water being discharged freely and over extraction of ground water by these industries. After analyzing the correlation between the parameters it was found that TDS showed a very strong relationship with conductivity and turbidity. The analysis revealed that the water of Bulandshahr is not good for drinking, thus it needed a pre-treatment before consumption and over extraction of ground water must be checked so as to curb the quality of ground water.
Research on software reuse methods based on the object-oriented components

Software reuse is considered as an effective method of avoiding duplication of work, improving the efficiency and quality of the software development. Software component technology is the core technology to support software reuse. In recent years, it has made a rapid development and has received a highly attention in the field of software reuse. The object-oriented technology has provided practical tools and basic theories which can be realized and applied in the software component. This paper will present the relationship between object-oriented methods and software reuse technology; it will also present the method process of extracting components in order to realize software reuse.
The co-evolution of a hype and a software architecture: experience of component-producing large-scale EJB early adopters

abaXX. components was one of the first AN software products fully based on Enterprise JavaBeans/spl trade/ (EJB) technology. We describe the evolution of its architecture as it moved from simply taking the initial EJB hype for the truth, through several intermediate stages, to using EJB simply as one of several encapsulated implementation techniques. So far, the public perception of how to use EJB properly evolved along a similar path, lagging 6 to 12 months behind.
A Forward Collision Warning Algorithm With Adaptation to Driver Behaviors

Significant effort has been made on designing user-acceptable driver assistance systems. To adapt to driver characteristics, this paper proposes a forward collision warning (FCW) algorithm that can adjust its warning thresholds in a real-time manner according to driver behavior changes, including both behavioral fluctuation and individual difference. This adaptive FCW algorithm overcomes the limit of traditional FCW with fixed risk evaluation models and fixed triggering thresholds by continuously monitoring driver braking behaviors in multiple lanes. A real-time identification algorithm for the warning thresholds is designed by using the recursive least squares method. Based on naturalistic experimental data, offline simulations show that this algorithm can match driver behavioral fluctuation and individual difference in long-time driving condition, and as time goes on, the adaptability to driver behavior is gradually improved, thus decreasing the false-alarm rate of FCW.
Novel Insights into CB1 Cannabinoid Receptor Signaling: A Key Interaction Identified between the Extracellular-3 Loop and Transmembrane Helix 2 s

Activation of the cannabinoid CB1 receptor (CB1) is modulated by aspartate residue D2.63 in transmembrane helix (TMH) 2. Interestingly, D2.63 does not affect the affinity for ligand binding at the CB1 receptor. Studies in class A G protein-coupled receptors have suggested an ionic interaction between residues of TMH2 and 7. In this report, modeling studies identified residue K373 in the extracellular-3 (EC-3) loop in charged interactions with D2.63. We investigated this possibility by performing reciprocal mutations and biochemical studies. D2.63A, K373A, D2.63A-K373A, and the reciprocal mutant with the interacting residues juxtaposed D2.63K-K373D were characterized using radioligand binding and guanosine 59-3-O-(thio) triphosphate functional assays. None of the mutations resulted in a significant change in the binding affinity of N-(piperidiny-1-yl)5-(4-chlorophenyl)-1-(2,4-dichloro-phenyl)-4-methyl-1H-pyrazole-3carboxamide hydrochloride (SR141716A) or (2)-3cis -[2-hydroxyl-4-(1,1-dimethyl-heptyl)phenyl]-trans-4-[3-hydroxyl-propyl] cyclohexan-1-ol (CP55,940). Modeling studies indicated that binding-site interactions and energies of interaction for CP55,940 were similar between wild-type and mutant receptors. However, the signaling of CP55,940, and (R)-(1)-[2,3-dihydro-5-methyl-3[(4-morpholinyl)methyl]-pyrrolo[1,2,3-de]-1,4-benzoxazin-6-yl](1naphthalenyl)-methanone mesylate (WIN55,212-2) was impaired at the D2.63A-K373A and the single-alanine mutants. In contrast, the reciprocal D2.63K-K373D mutant regained function for both CP55,940 and WIN55,212-2. Computational results indicate that the D2.63-K373 ionic interaction strongly influences the conformation(s) of the EC-3 loop, providing a structure-based rationale for the importance of the EC-3 loop to signal transduction in CB1. The putative ionic interaction results in the EC-3 loop pulling over the top (extracellular side) of the receptor; this EC-3 loop conformation may serve protective and mechanistic roles. These results suggest that the ionic interaction between D2.63 and K373 is important for CB1 signal transduction.
Conditioning circuit for precise SiC capacitive pressure sensors

Capacitive pressure sensor has many advantages, such as high sensitivity, low temperature drifting and low power consumption. In this paper, capacitive pressure sensor is used as pressure sensor. This paper analyzes SiC MEMS capacitive sensor's features and introduces its conditioning circuit. This sensor has widely commercial exploitation because of its small size and outstanding chemical stability as well as its mechanical character for harsh industrial environment application. Capacitance of this sensor varies at fF or pF degree. As a result, exploitation of such high sensitive capacitive pressure sensor is inhibited by parasitic capacitance in conditioning circuit. Integrated conditioning circuit is introduced for those high-sensitivity capacitive pressure sensors. Measures taken to reduce parasitic capacitance are described in the paper. Experience results give the range and linear area of this sensor.
Modified Gradient Techniques for Normalized Solution Vectors

We define a technique that is found to be useful when dealing with solution vectors (i.e., chromosomes) that must be normalized before evaluation. Normalized vectors can be either trivially manipulated or trivially interpreted, but not both. This paper studies some modified gradient techniques for both bit and floating point representations that have been successfully used at ARCO on some real world problems where other optimization techniques have failed.
Invariants of bi-Lipschitz equivalence of real analytic functions

We construct an invariant of the bi-Lipschitz equivalence of analytic function germs (R, 0) → (R, 0) that varies continuously in many analytic families. This shows that the bi-Lipschitz equivalence of analytic function germs admits continuous moduli. For a germ f the invariant is given in terms of the leading coefficients of the asymptotic expansions of f along the sets where the size of |x| |grad f(x)| is comparable to the size of |f(x)|. Introduction. Consider a one parameter family of germs ft(x, y) : (R, 0)→ (R, 0), t ∈ R, given by ft(x, y) = f(x, y, t) = x 3 − 3txy + y. (0.1) We shall show that if t 6= t′, t, t′ > 0, then ft and ft′ are not bi-Lipschitz equivalent, that is, there is no germ of bi-Lipschitz homeomorphism h : (R, 0) → (R, 0) such that ft ◦ h = ft′ . This shows in particular that the bi-Lipschitz classification of real analytic function germs admits continuous moduli. The existence of such moduli for complex analytic function germs was shown by the authors in [2]. We recall that, on the other hand, the bi-Lipschitz equivalence of complex or real analytic set germs does not admit moduli by [6] and [7], [8]. In order to distinguish bi-Lipschitz types of complex analytic function germs of two complex variables f : (C, 0) → (C, 0) we construct in [2] a numerical invariant that is given in terms of the leading coefficients of the asymptotic expansions of f along the branches of generic polar curve of f . This construction is recalled in Section 4 below. The 2000 Mathematics Subject Classification: 32S15, 32S05, 14H15. The paper is in final form and no version of it will be published elsewhere.
LILYPOND, A SYSTEM FOR AUTOMATED MUSIC ENGRAVING

A plastic light-transmitting fiber having a core-sheath structure. A polymer having methacrylimide or N-substituted methacrylimide units is used for the core component. A polymer having a refractive index smaller by at least 1% than that of the polymer of the core component is used for the sheath component. The heat resistance of the light-transmitting fiber is highly improved.
Human–Machine Interaction Issues in Quality Control Based on Online Image Classification

This paper considers on a number of issues that arise when a trainable machine vision system learns directly from humans. We contrast this to the ldquonormalrdquo situation where machine learning (ML) techniques are applied to a ldquocleanedrdquo data set which is considered to be perfectly labeled with complete accuracy. This paper is done within the context of a generic system for the visual surface inspection of manufactured parts; however, the issues treated are relevant not only to wider computer vision applications such as medical image screening but also to classification more generally. Many of the issues we consider arise from the nature of humans themselves: They will be not only internally inconsistent but also will often not be completely confident about their decisions, particularly if they are making decisions rapidly. People will also often differ systematically from each other in the decisions they make. Other issues may arise from the nature of the process, which may require the ML to have the capacity for real-time online adaptation in response to users' input. Because of this, it may be that the users cannot always provide input to a consistent level of detail. We describe how all of these issues may be tackled within a coherent methodology. By using a range of classifiers trained on data sets from a compact disc imprint production process, we present results which demonstrate that training methods designed to take proper consideration of these issues may actually lead to improved performance.
An Energy Model for Simulation Studies of Wireless Sensor Networks using OMNeT++

ABSTRACT Simulation is frequently used to evaluate the performance of networking algorithms and techniques in wireless communication networks. However, performance aspects such as the transmission delay, the channel utilization, or the throughput provide only limited information about the feasibility of the particular approach. This is especially the case when investigating Wireless Sensor Networks (WSNs), which stress energy-efficiency due to extremely limited power source in sensor nodes. Thus, a precise evaluation of the energy efficient performance is demanded. In this paper, we present a generic energy model developed for the simulation framework OMNeT++. The model allows to accurately evaluate the energy performance (in terms of energy consumption or network lifetime) of sensor networks (or in principle any wireless network), taking into account the energy consumption of both the radio transceiver and the CPU. The energy model can be calibrated to arbitrary types of sensor nodes if power measurements are available for the node type. The applicability of the developed energy model is demonstrated in a selected application scenario: the analysis of the energy consumption in IEEE 802.15. 4 star networks. Additionally, we outline the need for more complex metrics compared to the energy consumption of single nodes to evaluate the lifetime of the whole sensor network.
A Search for OH Megamasers at z > 0.1. I. Preliminary Results

We present the preliminary results of a survey for OH megamasers underway at the Arecibo ObservatoryThe Arecibo Observatory is part of the National Astronomy and Ionosphere Center, which is operated by Cornell University under a cooperative agreement with the National Science Foundation. The goals of the survey are to calibrate the luminosity function of OH megamasers to the low-redshift galaxy merger rate (0.1 < z < 0.2) and to use the enhanced sample of OH megamasers provided by the survey to study OH megamaser environments, engines, lifetimes, and structure. The survey should double the known OH megamaser sample to roughly 100 objects. Survey results will be presented in installments to facilitate community access to the data. Here we report the discovery of 11 OH megamasers and one OH absorber, and we include upper limits on the isotropic 1667 MHz OH line luminosity of 53 other luminous infrared galaxies at z > 0.1. The new megamasers show a wide range of spectral properties but are consistent with the extant set of 55 previously reported objects, only eight of which have z > 0.1.
DRDT: Distributed and Reliable Data Transmission with Cooperative Nodes for Lossy Wireless Sensor Networks

Recent studies have shown that in realistic wireless sensor network environments links are extremely unreliable. To recover from corrupted packets, most routing schemes with an assumption of ideal radio environments use a retransmission mechanism, which may cause unnecessary retransmissions. Therefore, guaranteeing energy-efficient reliable data transmission is a fundamental routing issue in wireless sensor networks. However, it is not encouraged to propose a new reliable routing scheme in the sense that every existing routing scheme cannot be replaced with the new one. This paper proposes a Distributed and Reliable Data Transmission (DRDT) scheme with a goal to efficiently guarantee reliable data transmission. In particular, this is based on a pluggable modular approach so that it can be extended to existing routing schemes. DRDT offers reliable data transmission using neighbor nodes, i.e., helper nodes. A helper node is selected among the neighbor nodes of the receiver node which overhear the data packet in a distributed manner. DRDT effectively reduces the number of retransmissions by delegating the retransmission task from the sender node to the helper node that has higher link quality to the receiver node when the data packet reception fails due to the low link quality between the sender and the receiver nodes. Comprehensive simulation results show that DRDT improves end-to-end transmission cost by up to about 45% and reduces its delay by about 40% compared to existing schemes.
Understanding interpersonal violence: the impact of temperatures in Mexico

We estimate the effect of temperature on criminality in Mexico and question conventional wisdom that high temperatures impact human psychology. Using high-frequency data, we find a linear effect of temperatures on criminality, inconsistent with the belief that only high temperatures cause disturbances. A significant share of weather-related crimes can be explained by higher alcohol consumption (9%) and changes in time allocation during weekends (17%). Also 28% of weather related crimes are committed at night, and temperatures are mild, and a third is driven by short term displacements, causing no additional victims.
TEROIDOGENIC ACUTE REGULATORY PROTEIN IN THE BRAIN

bstract—The nervous system synthesizes steroids that reglate the development and function of neurons and glia, and ave neuroprotective properties. The first step in steroidoenesis involves the delivery of free cholesterol to the inner itochondrial membrane where it can be converted into regnenolone by the enzyme cytochrome P450side chain leavage. The peripheral-type benzodiazepine receptor and he steroidogenic acute regulatory protein are involved in his process and appear to function in a coordinated manner. teroidogenic acute regulatory protein mRNA and protein are idely expressed throughout the adult brain. Steroidogenic cute regulatory protein expression has been detected in any neuronal populations, in ependymocytes, in some asroglial cells, in Schwann cells from peripheral nerves and in roliferating cells of the developing and adult brain. Steroiogenic acute regulatory protein is colocalized in the same eural cells with P450side chain cleavage and with other teroidogenic enzymes. Steroidogenic acute regulatory protein xpression in the brain shows marked changes with developent, aging and injury. The steroidogenic acute regulatory rotein gene may be under the control of diverse mechaisms in different neural cell types, since its expression is pregulated by cyclic AMP (cAMP) in gliomas and astrocytes n culture and downregulated by cyclic AMP (cAMP) in chwann cells. In addition, activation of N-methyl-D-aspartate eceptors, and the consequent rise in intracellular calcium evels, activates steroidogenic acute regulatory protein and teroidogenesis in hippocampal neurons. In conclusion, steoidogenic acute regulatory protein is regulated in the nerous system by different physiological and pathological conitions and may play an important role during brain developent, aging and after injury. © 2005 Published by Elsevier Ltd n behalf of IBRO.
Mixed correlation functions in the 2-matrix model, and the Bethe Ansatz

Using loop equation technics, we compute all mixed traces correlation functions of the 2-matrix model to large N leading order. The solution turns out to be a sort of Bethe Ansatz, i.e. all correlation functions can be decomposed on products of 2-point functions. We also find that, when the correlation functions are written collectively as a matrix, the loop equations are equivalent to commutation relations.
Mixed-instance querying: a lightweight integration architecture for data journalism

As the world's affairs get increasingly more digital, timely production and consumption of news require to efficiently and quickly exploit heterogeneous data sources. Discussions with journalists revealed that content management tools currently at their disposal fall very short of expectations. We demonstrate Tatooine, a lightweight data integration prototype, which allows to quickly set up integration queries across (very) heterogeneous data sources, capitalizing on the many data links (joins) available in this application domain. Our demonstration is based on scenarios we study in collaboration with Le Monde, France's major newspaper.
A CONCEPTUAL MODEL FOR USER-CENTRED PASSIVE BUILDING DESIGN

The integration of end user factors (EUFs) into passive building design processes is suggested to be of major importance for improving mental health and wellbeing of the -user (E-U). Currently, there is a lack of a robust approach that helps the designer to integrate these factors into the design processes. There is also a need to understand what the most relevant E-U factors are and how to integrate them into passive design processes. Hence, the thesis of this work is to address this challenge by proposing a systemic conceptual E-U centred passive building design model -U factors into the PD strategies. The UCPBDM approach is based on ISO 13407 and ISO 9126 standards. Accordingly, we extend the theory of passive design by systemising and incorporating E-U factors. Overall, our investigation builds knowledge by extending E-U centred design theory to passive building design context and by proving a list of effective E-U factors.
Improvement of Performance in JPEG2000 Lossy Compression by Signal Modulation

Improvement of performance in sub-band coding system that style in image coding system, is very important. In the coding systems, due to the filter bank that used, coding schemes are classified into two classes, one might have the pair-wise mirror-image property in their filter banks, and performs symmetrically regardless of the sign of the autocorrelation, and the other including JPEG2000 that uses bi-orthogonal 9/7-tap Daubechies filters for lossy compression, has not the mirror image property and performs asymmetrically with inferior performance for negative autocorrelation. In this paper, we want with modulating the negatively-correlated signal sequence by the alternating sign signal with unity magnitude to convert them into positively correlated-sequence. The experimental results for test images show that little gain was obtained by for natural images, since they have small amount of energy in the high frequency bands in horizontal and vertical directions. However 1.5-2dB improvement of PSNR has been obtained for images such as Fingerprint, which have a large amount of energy in high frequency range.
