description: The mechanical properties of a polymeric network containing both crosslinks and sliplinks (entanglements) are studied using a multi-chain Brownian dynamics simulation. We coarse-grain at the level of chain segments connecting consecutive nodes (cross- or sliplinks), with particular attention to the Gaussian statistics of the network. Affine displacement of nodes is not imposed: their displacement as well as sliding of monomers through sliplinks is governed by force balances. The simulation results of stress in uniaxial extension and the full stress tensor in simple shear including the (non-zero) second normal stress difference are presented for monodisperse chains with up to 18 entanglements between two crosslinks. The cases of two different force laws of the subchains (Gaussian chains and chains with finite extensibility) for two different numbers of monomers in a subchain (no = 50 and no = 100) are examined. It is shown that the additivity assumption of slip- and crosslink contribution holds for sufficiently long chains with two or more entanglements, and that it can be used to construct the strain response of a network of infinitely long chains. An important consequence is that the contribution of sliplinks to the small-strain shear modulus is about ⅔ of the contribution of a crosslink.

description: Due to recent development in laser technology and infrared spectroscopy, Laser-based spectroscopy (LAS) has been used in a wide range of research and application fields. A particular application of interest is mid-IR laser-based gas detection systems for health and environment assessment. The NSF-ERC Mid-Infrared Technologies for Health and Environment (MIRTHE) project has engineers and researchers from different areas. As a participant in MIRTHE, we study the performance analysis and improvement possibilities of the integrated sensing system. Herein, we have improved the developed statistical analysis model, and then used our statistical analysis model for a generic mid-IR pulsed-laser gas detection system to predict trace gas detection and concentration estimation performance, and their sensitivity to system parameters. Based on PNNL (Pacific Northwest National Laboratory) data and the Beer-Lambert law, we defined three main spectral peaks of a trace gas for detecting target gas and evaluate 3-peak joint detection performance in terms of PD vs PFA. For concentration estimation we used the relationship between gas transmittance ?, molar absorptivity ?, concentration c, the sample-mean measurement, xN, from the photo-detector, and number of samples, N, as the basis. Using the standard confidence interval method, we evaluated estimation reliability, and then analyzed estimation errors. Analytical gas detection and concentration estimation results are presented for 17 trace gases at 1 ppm and 1 ppb concentrations.

Subjects: Computer Science (0984)

description: Research on Mobile Ad-Hoc Networks (MANETs) becomes popular in recent years because of the widespread wireless networking devices and the need of communication among them. Because of the tiresome of delpoyment of a real MANETs, researchers often utilize simulators to evaluate their research. There are several popular simulators such as OPNET, ns-2, and Glomosim for researchers to choose. All simulators provide toolkit for researchers to validate or collect data from their designs. The accuracy of simulators depends on how the simulated behaviors match as closely as possible the reality.; A lot of research has been conducted on MANETs, most of them are related to routing protocols. However, most of the time, researchers are focused on the models that are evaluated, but the interaction with other layers are not considered sufficiently. The neglect of the influence of other layers in simulation could ruin the research. Some research shows the influence of cross layer interaction of simulation of MANETs, but how radio propagation and interference have impacts on MANETs is still not clear.; In this thesis, we investigate four radio propagation models - Free Space, Two Ray, Okumura-Hata, and Irregular Terrain Models, and then integrate them into the simulator, Glomosim, and try to find out how these models and interference affect the evaluations of MANETs. We use average end-to-end delay and packet delivery ratio to compare the performance of different combination scenarios including pathloss models, fading models, sizes of environment, and radio receving types. Our simulation results show that radio propagation models have impacts on the performance of MANETs.
A case study of participation and critical thinking in a university-level course delivered by computer conferencing
Creators: name: Bullen, Mark
Publisher: name: University of British Columbia
Year: 2009

description: Despite the growth in the size and acceptance of distance education, there have been persistent criticisms of this form of education because it often fails to provide for interaction among students and between students and instructors. Without this, it is suggested, distance education can only be an inferior imitation of the best face-to-face education because learners are unable to clarify and challenge assumptions and to construct meaning through dialogue. Some critics believe distance education's inability to reproduce a critical dialogue among students and between students and instructor can be addressed through the use of two-way communication technologies such as text-based, asynchronous (i.e., not in real time) computer conferencing. Appropriately-designed computer conferencing, it is argued, will facilitate interaction among students and between the instructor and students thus making distance education more appropriate for the higher-level cognitive goals of college and university education. At the same time, using this' technology will retain the flexibility of time and place-independence that is characteristic of distance education. The literature on educational computer conferencing is replete with references to its potential to create a new paradigm of education characterized by interactive group knowledge-building and critical thinking, but there are few empirical studies that have substantiated this view. Little is known about how and why learners participate and what factors may affect their participation. Similarly there has been little empirical study of the quality of computer conferencing interaction. This case study of a university-level course delivered by computer conferencing was designed to address these issues. It was guided by two purposes: 1) to determine whether the quantitative and qualitative dimensions of participation in this online course were consistent with key aspects of the new paradigm of networked learning as articulated in the literature, that is, if students were actively participating, building on each others contributions and thinking critically about the discussion topics; and 2) to determine what factors affected student participation and critical thinking. The results of this study suggest that some of the claims about the potential of this technology to transform conventional and distance education may be overstated. The emergence of a dynamic and interactive educational process that facilitates critical thinking was shown to be contingent on a variety of factors. The results suggest, however, that with the appropriate course design, instructor interventions, content, and students, computer conferencing can be used for these purposes and should be given serious consideration by distance educators as a way of facilitating interaction and critical thinking in distance education.

description: Masses of the eta and eta-prime mesons are estimated in Nf=2+1 lattice QCD with the non-perturbatively O(a) improved Wilson quark action and the Iwasaki RG-improved gluon action, using CP-PACS/JLQCD configurations on a 16^3 x 32 lattice at beta=1.83 (lattice spacing is 0.122 fm). We apply a stochastic noise estimator technique combined with smearing method to evaluate correlators among flavor SU(2) singlet pseudoscalar operators and strange pseudoscalar operators for 10 combinations of up/down and strange quark masses. The correlator matrix is then diagonalized to identify signals for mass eigenstates. Masses of the ground state and the first excited state extrapolated to the physical point are m_eta= 0.545(16) GeV and m_eta-prime= 0.871(46) GeV, being close to the experimental values of the eta and eta-prime masses.

Year: 2009
Subjects: Suffix Arrays

description: A suffix array is a simple and powerful data structure that has numerous applications such as string matching and text compression. Many algorithms have been written to efficiently construct suffix arrays. One of the linear time algorithms, DC-3 has already been converted into an external memory as well as into a scalable internal memory parallel algorithm. However, there are situations in which there is a need for computing in external memory, while scalable parallelism is needed at the same time in order to speed up the computation. We have developed the first parallel external memory DC-3 algorithm. We have implemented our parallel external memory DC-3 algorithm using C and MPI. Measurements were performed on the Bluegrit cluster using IBM JS-20s and PVFS file system. The experiments show a good scaling factor and result in the conclusion that it is likely that our algorithm can be used to construct extremely large suffix arrays much faster.

description: A study is made of the behavior of massive black holes in disk galaxies that have received an impulsive kick from a merger or a sustained acceleration from an asymmetric jet. The motion of the gas, stars, dark matter, and massive black hole are calculated using the GADGET-2 simulation code. The massive black hole escapes the galaxy for kick velocities above about 600 km/s or accelerations above about 4*10^{-8} cm/s^2 over time-scales of the order of 10^8 yr. For smaller velocity kicks or smaller accelerations, the black hole oscillates about the center of mass with a frequency which decreases as the kick velocity or acceleration increases. The black hole displacements may give rise to observable nonaxisymmetries in the morphology and dynamics of the stellar and gaseous disk of the galaxy. In some cases the dynamical center of the galaxy is seen to be displaced towards the direction of the BH acceleration with a characteristic ``tongue--'' shaped extension of the velocity contours on the side of the galaxy opposite the acceleration.

description: Wireless sensor networks (WSNs) have recently received increasing attention due to a growing list of applications.  Most notable among the applications are those in harsh environments, such as coast and border protection, search-and-rescue and battlefield reconnaissance.  A WSN in these applications may get partitioned into multiple disjoint segments (sub-networks) due to major damage in some part of the network, e.g. inflicted by explosions in battlefield.  Since WSNs are often employed to assist in risky missions and to deal with the event that caused the damage itself, it is desired to connect these disjoint partitions in order to restore the full operation of the network.  In addition, linking sub-networks may be mandatory in some application setups in which there are multiple autonomous, independently-operating, WSNs that need to collaborate to perform a joint task.  For example, a number of existing stand-alone WSNs may be required to operate jointly in order to deal with a major disaster. Connecting multiple WSNs or segments of a damaged WSN is referred to as federation in this dissertation.  In this dissertation, we tackle the challenges in federating a partitioned WSN or autonomous wireless sensor sub-networks.  In particular, we form a federated system of multiple network segments by deploying the least number of additional relay nodes in the proper locations.  We focus on two major factors related to relay placement.  The first is the connectivity requirement which is characterized by the distances between every pair of two segments.  Those distances may be longer than twice the communication range of a single relay node, which requires consideration of the inter-relay connectivity.  In addition, linking the segments may be subject to varying inter-segment quality of service (QoS) requirements.  Since finding the optimal count and position of relay nodes is known to be NP-hard, we pursue heuristics. We present three novel approaches in this dissertation.  The first approach populates relays towards the center of the area to form a connected inter-segment topology.  In the second approach, we design a distributed self-healing algorithm which repositions existing mobile nodes to connect the segments.  The third approach incrementally places the relays, addressing the connectivity and QoS requirements one path at a time.  It opts to minimize the number of required relays to establish connectivity by maximizing the resource utilization of the deployed nodes.  The correctness, convergence and time complexity of those proposed approaches are analyzed and their effectiveness is evaluated through extensive simulation experiments. The resulting topology is also analyzed in comparison to alternate solutions found in the literature.

description: An exoskeleton is a wearable electromechanical structure that is intended to resemble and allow movements in a manner similar to the human skeletal system. They can be used by both disabled and able people alike to increase physical strength in carrying out tasks that would be otherwise difficult, or as a rehabilitation device to aid in physiotherapeutic activities of a weakened body part. This paper intends to introduce a voicecontrolled upper body exoskeleton for industrial applications which can aid workers wearing it by reducing stresses on their arms and shoulders over longer periods and add up to 20kg more strength in lifting applications. The 3D design, calculations and considerations, and load analysis are presented along with brief results of a basic prototype model of the exoskeleton.

On the Use of Context and Policies in Declarative Networked Systems

description: Managing complex networks while ensuring that certain high level goals such as security are met is a complicated process. This is evidenced by the recent Internet outages caused by operators misconfiguring BGP routers. Clearly, there is a growing need to separate the high level goals/policies from the low level mechanisms that implement the various services. We propose a declarative framework for specifying and enforcing high level policies in networks. The declarative framework offers flexibility in terms of specifying the higher level goals rather than focusing on the lower level mechanisms employed in the implementation, and robustness in terms of recovering from failure. One of the key building blocks of our framework is to allow applications to expose their semantics, thereby allowing the underlying network to exploit the semantics and provide better-than-best-effort service where possible. Our framework employs semantic web languages such as OWL and RDF to formally express application and network specifications, and thereby leverages the inherent reasoning and conflict resolution capabilities of these languages. Once the applications and networks are formally specified in our framework, operators can write adaptation policies to jointly adapt the application and network layers in response to changing network conditions. We demonstrate our approach by applying it to a variety of diverse problems in network configuration and management. Our experiments with video over wireless show that the joint adaptation provides higher performance compared to no adaptation as well as application/network layer alone adaptation. Furthermore, the adaptation policies are easy to express in our framework and can be dynamically changed at run time. We also show how our framework can be used to automatically configure BGP routers. High level organizational routing policies can be captured in our framework through appropriate ontological specifications. These specifications which can then be checked for correctness are automatically compiled into appropriate low level BGP configurations by our framework and installed on the routers. Furthermore, the logical basis of our specifications enables reasoning, and routers can engage in an argumentation with their neighbors to diagnose and recover from routing misconfigurations through policy controlled reconfigurations. In cases where the argumentation protocol does not converge or the reconfiguration needed is not permitted by policy, the network administrator is alerted along with a log of the argumentation protocol executed so far, helping in isolating the location and cause of failure.

description: Hintergrund: Die Berufseinmündung professionell Pflegender stellt eine sensible und aufregende Phase im Leben oft junger Menschen dar. In diesem Rahmen ergeben sich nicht nur vielfältige Herausforderungen, sondern auch Chancen.

Zielsetzung: Diese Masterarbeit verfolgt das Ziel, das Erleben des Berufseinstiegs nach der generalistischen Pflegeausbildung zu untersuchen. Dabei stehen Herausforderungen und Chancen, die sich den Berufseinsteiger_innen im Bereich der stationären Akutversorgung stellen, im Fokus.

Methodik: Nach einer Literaturrecherche und der Identifikation bestehender Befunde zum Berufseinstieg professionell Pflegender dienen die gewonnenen Erkenntnisse zur Entwicklung eines deduktiven Kategoriensystems. Im Rahmen des qualitativen Forschungsdesigns bildet dieses Kategoriensystem die Basis für die episodischen Interviews nach Flick mit sechs Berufseinsteiger_innen. Anschließend werden die transkribierten Interviews mit Hilfe der strukturierenden Inhaltsanalyse nach Mayring analysiert und ausgewertet.

Ergebnisse: Die Berufseinsteiger_innen erleben sowohl vielfältige Herausforderungen als auch Chancen in unterschiedlichen Bereichen. Als besonders herausfordernd beschreiben sie den Übergang in die neue Rolle als examinierte Pflegefachperson mit der neuen Verantwortung sowie den Umgang mit fehlendem spezialisiertem Fachwissen. Unterstützung erfahren die Befragten vor allem durch das Pflegeteam der Station sowie durch Möglichkeiten zur Fort- und Weiterbildung. 

Schlussfolgerungen: Der Berufseinstieg stellt eine herausfordernde Phase dar und sollte durch entsprechende Programme begleitet werden, die insbesondere die Übernahme von Verantwortung und die Aneignung von spezialisiertem Fachwissen fokussieren, um so eine optimale Unterstützung der neu examinierten Pflegefachfrauen und Pflegefachmänner zu gewährleisten. Zusätzlich können bereits in der Ausbildung Grundsteine für einen erfolgreichen Berufseinstieg gelegt werden. Dies könnte durch eine gute Verzahnung von Theorie und Praxis, die frühe Vermittlung personaler Kompetenzen und das schrittweise Heranführen an selbständiges Arbeiten mit der Übernahme von Verantwortung in einem geschützten Rahmen, gelingen.
Positive and negative-parity flavor-octet baryons in coupled QCD sum rules

description: We apply the method of the QCD sum rule, in which positive- and negative-parity baryons couple with each other, to the flavor-octet hyperons and investigate the parity splittings. We also reexamine the nucleon in the method, which was studied in our previous paper, by carefully choosing the Borel weight. Both in the nucleon and hyperon channels the obtained sum rules turn out to have a very good Borel stability and also have a Borel window, an energy region in which the OPE converges and the pole contribution dominates over the continuum contribution. The predicted masses of the positive- and negative-parity baryons reproduce the experimental ones fairly well in the $Λ$ and $Σ$ channels, if we assign the $Λ(1670)$ and the $Σ(1620)$ to the parity partners of the $Λ$ and the $Σ$, respectively. This implies that the $Λ(1405)$ is not the party partner of the $Λ$ and may be a flavor-singlet or exotic state. In the $Ξ$ channel, the sum rule predicts the mass of the negative-parity state to be about 1.8 GeV, which leads to two possibilities; one is that the observed state with the closest mass, $Ξ(1690)$, is the parity partner and the other is that the parity partner is not yet found but exists around 1.8 GeV.

description: Lead-free Ba0.85Ca0.15Zr0.10Ti0.90O3 (BCZT) ceramics have demonstrated excellent dielectric, ferroelectric and piezoelectric properties in comparison to lead-based materials. The synthesis of pure and crystalline BCZT nanopowders at low temperatures of 25, 80 and 160 C was reported previously by using a sol-gel method followed by a hydrothermal route. In this study, the structural, dielectric and ferroelectric properties of sintered BCZT ceramics at 1250 °C for 10h were investigated. XRD measurements revealed the presence of a single perovskite phase at room temperature with the coexistence of the orthorhombic and tetragonal symmetries. The increase of grain size and the ceramic density in BCZT ceramics result in an enhancement of the dielectric and ferroelectric properties of BCZT ceramics. More interestingly, the synthesis temperature of BCZT powders with high dielectric and ferroelectric properties could be decreased to a low temperature of 160 °C, which is about 1200 °C lower when compared with solid-state reaction and 840 °C lower when compared with sol-gel methods. The BCZT ceramics elaborated at 160 °C revealed excellent electrical properties. Hence, the use of low-temperature hydrothermal processing can be encouraging for the synthesis of lead-free ceramics with high dielectric and ferroelectric properties.

description: This review provides an introduction to two dimensional growth processes. Although it covers a variety processes such as diffusion limited aggregation, it is mostly devoted to a detailed presentation of stochastic Schramm-Loewner evolutions (SLE) which are Markov processes describing interfaces in 2D critical systems. It starts with an informal discussion, using numerical simulations, of various examples of 2D growth processes and their connections with statistical mechanics. SLE is then introduced and Schramm's argument mapping conformally invariant interfaces to SLE is explained. A substantial part of the review is devoted to reveal the deep connections between statistical mechanics and processes, and more specifically to the present context, between 2D critical systems and SLE. Some of the SLE remarkable properties are explained, as well as the tools for computing with SLE. This review has been written with the aim of filling the gap between the mathematical and the physical literatures on the subject.

description: In this paper, we consider the normalized Bessel function of index $α> -\frac{1}{2}$, we find an integral representation of the term $x^nj_{α+n}(x)j_α(y)$. This allows us to establish a product formula for the generalized Hankel function $B^{κ,n}_λ$ on $\mathbb{R}$. $B^{κ,n}_λ$ is the kernel of the integral transform $\mathcal{F}_{κ,n}$ arising from the Dunkl theory. Indeed we show that $B^{κ,n}_λ(x)B^{κ,n}_λ(y)$ can be expressed as an integral in terms of $B^{κ,n}_λ(z)$ with explicit kernel invoking Gegenbauer polynomials for all $n\in\mathbb{N}^\ast$. The obtained result generalizes the product formulas proved by M. Rösler for Dunkl kernel when n=1 and by S. Ben Said when $n=2$. \\ As application, we define and study a translation operator and a convolution structure associated to $B^{κ,n}_λ$. They share many important properties with their analogous in the classical Fourier theory.
On the spread of epidemics in a closed heterogeneous population

Subjects: subject: Populations and Evolution (q-bio.PE)

description: Heterogeneity is an important property of any population experiencing a disease. Here we apply general methods of the theory of heterogeneous populations to the simplest mathematical models in epidemiology. In particular, an SIR (susceptible-infective-removed) model is formulated and analyzed for different sources of heterogeneity. It is shown that a heterogeneous model can be reduced to a homogeneous model with a nonlinear transmission function, which is given in explicit form. The widely used power transmission function is deduced from a heterogeneous model with the initial gamma-distribution of the disease parameters. Therefore, a mechanistic derivation of the phenomenological model, which mimics reality very well, is provided. The equation for the final size of an epidemic for an arbitrary initial distribution is found. The implications of population heterogeneity are discussed, in particular, it is pointed out that usual moment-closure methods can lead to erroneous conclusions if applied for the study of the long-term behavior of the model.

description: We report the experimental and theoretical studies of a magnetic topological nodal line semimetal candidate HoSbTe. Single crystals of HoSbTe are grown from Sb flux, crystallizing in a tetragonal layered structure (space group: P4/nmm, no.129), in which the Ho-Te bilayer is separated by the square-net Sb layer. The magnetization and specific heat present distinct anomalies at 4 K related to an antiferromagnetic (AFM) phase transition. Meanwhile, with applying magnetic field perpendicular and parallel to the crystallographic c axis, an obvious magnetic anisotropy is observed. Electrical resistivity undergoes a bad-metal-like state below 200 K and reveals a plateau at about 8 K followed by a drop due to the AFM transition. In addition, with the first-principle calculations of band structure, we find that HoSbTe is a topological nodal line semimetal or a weak topological insulator with or without taking the spin-orbit coupling into account, providing a platform to investigate the interplay between magnetic and topological fermionic properties.

description: We report on the first results of an imaging survey to detect strong gravitational lensing targeting the richest clusters selected from the photometric data of the Sloan Digital Sky Survey (SDSS) with follow-up deep imaging observations from the Wisconsin Indiana Yale NOAO (WIYN) 3.5m telescope and the University of Hawaii 88-inch telescope (UH88). The clusters are selected from an area of 8000 deg^2 using the Red Cluster Sequence technique and span the redshift range 0.1 < z < 0.6, corresponding to a comoving cosmological volume of ~ 2 Gpc^3. Our imaging survey thus targets a volume more than an order of magnitude larger than any previous search. A total of 240 clusters were imaged of which 141 had sub-arcsecond image quality. Our survey has uncovered16 new lensing clusters with definite giant arcs, an additional 12 systems for which the lensing interpretation is very likely, and 9 possible lenses which contain shorter arclets or candidate arcs which are less certain and will require further observations to confirm their lensing origin. The number of new cluster lenses detected in this survey is likely > 30. Among these new systems are several of the most dramatic examples of strong gravitational lensing ever discovered with multiple bright arcs at large angular separation. These will likely become 'poster-child' gravitational lenses similar to Abell 1689 and CL0024+1654. The new lenses discovered in this survey will enable future sysetmatic studies of the statistics of strong lensing and its implications for cosmology and our structure formation paradigm.

description: The temperature dependence of optical excitation life-time, Gamma, and transition energies, E_ii, were measured for bucky-papers of single-wall carbon nanotubes (SWCNTs) and inner tubes in double-wall carbon nanotubes (DWCNTs) using resonant Raman scattering. The temperature dependence of Gamma and E_ii is the same for both types of samples and is independent of tube chirality. The data proves that electron-phonon interaction is responsible for temperature dependence of E_ii(T). The temperature independent inhomogeneous contribution to Gamma is much larger in the SWCNT samples, which is explained by the different SWCNT environment in the two types of samples. Gamma of the inner tubes for the bucky-paper DWCNT sample is as low as \sim 30 meV, which is comparable to that found for individual SWCNTs.

description: Ο θυρεοειδής είναι ένας πλέον σημαντικός ενδοκρινής αδένας του ανθρώπου καθώς ρυθμίζει το μεταβολικό ρυθμό του οργανισμού. Οι περισσότερες καλοήθεις όσο και κακοήθεις καταστάσεις του θυρεοειδή αντιμετωπίζονται κυρίως χειρουργικά και κατά κόρων με τη κλασσική ανοικτή θυρεοειδεκτομή. Ωστόσο με την πάροδο των ετών αναπτύχθηκαν εναλλακτικές τεχνικές όπως η ενδοσκοπική και η ρομποτική. Η ανοικτή τεχνική προτιμάται ως θεραπεία για τις κακοήθειες καθώς εξασφαλίζει εξαιρετικά ογκολογικά αποτελέσματα. Παρόλα αυτά η ρομποτική διαμασχαλιαία θυρεοειδεκτομή (RATT) κερδίζει όλο και περισσότερο έδαφος στην αντιμετώπιση των καλώς διαφοροποιημένων καρκίνων καθώς αναδεικνύεται πως η αποτελεσματικότητας και η αξιοπιστία της είναι συγκρίσιμες με της ανοικτής θυρεοειδεκτομής. Η παρούσα εργασία αποτελεί μια βιβλιογραφική ανασκόπηση της συμβολής και της αποτελεσματικότητας της ρομποτικής διαμασχαλιαίας θυρεοειδεκτομής, δίχως τη χρήση αερίου CO2, με τη χρήση του ρομποτικού συστήματος Da Vinci, στην αντιμετώπιση του καλώς διαφοροποιημένου καρκίνου του θυρεοειδούς αδένα (θηλώδες, θηλακιώδες, καρκίνωμα από κύτταρα Hurthle).
description: The thyroid is one of the most important endocrine glands in humans as it regulates the body's metabolic rate. Most benign and malignant conditions of the thyroid are mainly treated surgically, predominantly with the classical open thyroidectomy. However, over the years, alternative techniques such as endoscopic and robotic methods have been developed. The open technique is preferred as a treatment for malignancies because it ensures excellent oncological outcomes. Nevertheless, robotic transaxillary thyroidectomy (RATT) is gaining more ground in the treatment of well-differentiated cancers as its effectiveness and reliability are emerging to be comparable to open thyroidectomy. This work is a literature review of the contribution and effectiveness of robotic transaxillary thyroidectomy, without the use of CO2 gas, using the Da Vinci robotic system, in the treatment of well-differentiated thyroid gland cancer (papillary, follicular, Hurthle cell carcinoma).

Negotiating expectations : how community health nurses conceptualize health promotion in the context of their practice
Creators: name: Ryan, Deborah
Publisher: name: University of British Columbia
Year: 2009

description: The theory and rhetoric of health promotion are proclaimed in academic circles, the policies are decreed by those in control of health service organizations, but little attention has been given to how the people expected to apply these ideas to social action are managing change. The purpose of this research was to generate an inductive theory of how community health nurses (CHNs) describe their conceptualizations of health promotion within the context of their practice. The initial research question was: how have CHNs transformed policy and management expectations into action at the messy, indeterminate place of clients and community? What have been their supports in this process? What have been the barriers? The grounded theory, negotiating expectations, provides an explanation of how CHNs cope with the multiple and diverse demands they experience in the context of their practice as they implement health promotion. Negotiating expectations is the fulcrum process in the theory and facilitating possibilities describes how they conceptualize health promotion as a currently preferred facet of their practice. This theory provides a guide for implementation of any innovation in community health nursing. It also contributes to a better understanding of the dialectic of policy, implementation and adaptation.

description: Segmentation of handwritten document images into text lines and words is one of the most significant and challenging tasks in the development of a complete Optical Character Recognition (OCR) system. This paper addresses the automatic segmentation of text words directly from unconstrained Bangla handwritten document images. The popular Distance transform (DT) algorithm is applied for locating the outer boundary of the word images. This technique is free from generating the over-segmented words. A simple post-processing procedure is applied to isolate the under-segmented word images, if any. The proposed technique is tested on 50 random images taken from CMATERdb1.1.1 database. Satisfactory result is achieved with a segmentation accuracy of 91.88% which confirms the robustness of the proposed methodology.

description: We consider an invariant skew-symmetric phase-space metric for non-Hamiltonian systems. We say that the metric is an invariant if the metric tensor field is an integral of motion. We derive the time-dependent skew-symmetric phase-space metric that satisfies the Jacobi identity. The example of non-Hamiltonian systems with linear friction term is considered.

description: We demonstrate sensitivity of the Mn 3d valence states to strain in the ferromagnetic semiconductors (Ga,Mn)As and (Al,Ga,Mn)As, using x-ray magnetic circular dichroism (XMCD). The spectral shape of the Mn $L_{2,3}$ XMCD is dependent on the orientation of the magnetization, and features with cubic and uniaxial dependence are distinguished. Reversing the strain reverses the sign of the uniaxial anisotropy of the Mn $L_3$ pre-peak which is ascribed to transitions from the Mn 2p core level to p-d hybridized valence band hole states. With increasing carrier localization, the $L_3$ pre-peak intensity increases, indicating an increasing 3d character of the hybridized holes.

description: This paper analyses the robust stability and performance of the Disturbance Observer- (DOb-) based digital motion control systems in discrete-time domain. It is shown that the phase margin and the robustness of the digital motion controller can be directly adjusted by tuning the nominal plant model and the bandwidth of the observer. However, they have upper and lower bounds due to robust stability and performance constraints as well as noise-sensitivity. The constraints on the design parameters of the DOb change when the digital motion controller is synthesised by measuring different states of a servo system. For example, the bandwidth of the DOb is limited by noise-sensitivity and waterbed effect when velocity and position measurements are employed in the digital robust motion controller synthesis. The robustness constraint due to the waterbed effect is removed when the DOb is implemented by acceleration measurement. The design constraints on the nominal plant model and the bandwidth of the observer are analytically derived by employing the generalised Bode Integral Theorem in discrete-time. The proposed design constraints allow one to systematically synthesise a high-performance DOb-based digital robust motion controller. Experimental results are given to verify the proposed analysis and synthesis methods.

description: According to www.the-numbers.com/market/, gross revenue for the Hollywood movie industry was over USD 10 billion in 2009. With annual revenues at this scale, it is critical for a movie to be successful at the box office. High revenue is closely linked to Oscar award nominations and hence to winning of the award. Building predictive models for nominations can provide useful insights into predicting Oscar awards. Using a movie script as a movie representation, we rank movie scenes and retrieve features from regression of the movie scene ranking. We introduce a model using Support Vector Machines, which predicts Oscar award nominations in the Best Screenplay and Best Picture categories. We build three baselines using random decision, bag-of-words and IMDb features respectively. Prediction results show that features from movie scripts contain information which is useful in predicting Oscar award nominations.
