Extended Object Tracking based on Combined Set-Theoretic and Stochastic Fusion
Creators: name: Baum, Marcus
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: In this paper, a novel approach for tracking extended objects is presented. The target object is modeled as a circular disc such that the center and extent of the target object can be estimated. At each time step, a finite set of position measurements that are corrupted with stochastic noise may be available. Each position measurement stems from an unknown measurement source on the extended object. In contrast to existing approaches, no statistical assumptions about the distribution of the measurement sources on the extended object are made. As a consequence, it is necessary to deal with stochastic and set-valued uncertainties. For this purpose, a novel combined stochastic and set-theoretic estimator that employs random hyperboloids to express the uncertainties about the true circular disc is derived.
Melville's White Whale: Pragmatism's Role in Moby Dick

Subjects: classificationCode: 4705

description: Many scholars have broached the subject of Melville's relation to pragmatism, but in most cases, they have merely grazed it. This thesis unpacks this complex relationship in detail. I begin by giving a basic overview of pragmatism, including its history and its methodology. Next, I show how Melville was well read in Emerson, who is also considered a proto-pragmatist. And then, through a close analysis of Moby Dick, I show how Melville illuminates the main tenets of this philosophy before it was even created. Through the characters of Ishmael and Ahab, Melville provides the archetypes for empiricism and absolutism, and yet he gives each character pragmatic values and vices. Ultimately, I also show how Melville grapples with pragmatism's most frustrating qualities, which brings his own philosophical beliefs to light, and shows how Melville leaves his unanswered relation to truth to the reader to decide.
Probing the chemistry and morphology of material interfaces in emerging photovoltaics

description: Emerging photovoltaics hold great promise to add to the existing solar cell market by either becoming cost competitive or accessing new, niche markets unavailable to current technologies. Unfortunately, wide adoption of these systems, in particular organic photovoltaics (OPVs) and perovskite photovoltaics, is hampered by overall poor performance in either efficiency (in OPVs) or in long-term stability (in perovskite photovoltaics). Designing better materials and optimizing device morphology/architectures, with the latter changing intrinsic material interfaces within the devices, has made progress to overcome some of these issues. Since these interfaces affect overall efficiency and stability, understanding interface chemistry (composition) and morphology is important in understanding overall device performance. Characterization of these interfaces requires techniques capable of probing the chemistry-morphology relationship at the nanoscale. Here, we use Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) and Atomic Force Microscopy (AFM) to characterize these material systems and their device interfaces. In P3HT:PCBM, a classic OPV system, we directly imaged the active layer buried morphology and determined the mixing length of the D/A interface, which is crucial for device performance and had yet to be measured. We determined, contrary to the general understanding, that thermal annealing in this system actually leaves the bulk heterojunction film mostly mixed. Our methodology provides a route to determining this D/A interface length for other OPV systems providing a new metric and insight for better device design principles. For MAPbI₃ perovskites, we studied interfacial behavior to understand light-induced degradation in functioning devices and electrical-induced degradation in films based on contact selection as well as visualized bias-induced ion migration. We determined that the PDI-EH electron transport layer hinders degradation; whereas, a PCBM electron transport layer allows and facilitates it. For electrical degradation, we determined that an ITO electrode induces more degradation than a platinum contact by measuring interface MAPbI₃/ITO mixing. And, by using lateral MAPbI₃ devices, we visualized ion migration due to an applied electric field. For perovskite devices, interfacial behavior dictates long-term performance. Overall, using a combination of ToF-SIMS and AFM to interrogate interfacial chemistry and morphology, we are working towards better devices through understanding limits on efficiency and stability.

description: The Kepler Mission Science Operations Center (SOC) performs several critical functions including managing the ~156,000 target stars, associated target tables, science data compression tables and parameters, as well as processing the raw photometric data downlinked from the spacecraft each month. The raw data are first calibrated at the pixel level to correct for bias, smear induced by a shutterless readout, and other detector and electronic effects. A background sky flux is estimated from ~4500 pixels on each of the 84 CCD readout channels, and simple aperture photometry is performed on an optimal aperture for each star. Ancillary engineering data and diagnostic information extracted from the science data are used to remove systematic errors in the flux time series that are correlated with these data prior to searching for signatures of transiting planets with a wavelet-based, adaptive matched filter. Stars with signatures exceeding 7.1 sigma are subjected to a suite of statistical tests including an examination of each star's centroid motion to reject false positives caused by background eclipsing binaries. Physical parameters for each planetary candidate are fitted to the transit signature, and signatures of additional transiting planets are sought in the residual light curve. The pipeline is operational, finding planetary signatures and providing robust eliminations of false positives.

Cumulative environmental assessment in Tasmania : a catchment case study
Creators: name: Harvey, A
Publisher: name: University Of Tasmania
Year: 2023

description: The cumulative impact of multiple stressors on the environment over time and space has been acknowledged as a key process in the ongoing loss of habitat and biodiversity and as a driver of landscape change. Regulatory approaches that address environmental impacts only at the level of the individual project footprint may facilitate significant environmental impacts through the cumulative effects of those projects. Such approaches are unlikely to ensure that current and future development of natural resources is sustainable. The catchment spatial scale and the regulatory processes that govern three key activities within it - farm dams, forest practices and water abstraction - form the basis for an examination of cumulative effects in Tasmania. International and Commonwealth regulatory approaches to cumulative effects, key concepts and methodologies are examined through a literature review. The potential cumulative impact of farm dams, forest practices and water abstraction on the natural flow regime, freshwater ecological processes and biota is established through the relevant literature. A case study of the Great Forester ‚ÄövÑvÆ Brid catchment in north east Tasmania is used to determine the potential for these impacts to occur in Tasmanian catchments. The results of this study show that there are measurable cumulative impacts on the natural flow regime, connectivity and special natural values within the catchment. Relevant legislation, policies and processes are examined to establish an understanding of how cumulative effects are addressed in Tasmania for these activities. Cumulative impacts of these activities are not adequately addressed in the current legislative and policy environment in Tasmania. An explicit legislative requirement for cumulative effects needs to be considered. In addition a pro-active, regional framework to manage and assess cumulative effects, incorporating integrated catchment management, is a fundamental requirement for the sustainable use of natural resources in Tasmania.

Gaussian Filtering using State Decomposition Methods
Creators: name: Beutler, Frederik
name: Huber, Marco F.
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: State estimation for nonlinear systems generally requires approximations of the system or the probability densities, as the occurring prediction and filtering equations cannot be solved in closed form. For instance, Linear Regression Kalman Filters like the Unscented Kalman Filter or the considered Gaussian Filter propagate a small set of sample points through the system to approximate the posterior mean and covariance matrix. To reduce the number of sample points, special structures of the system and measurement equation can be taken into account. In this paper, two principles of system decomposition are considered and applied to the Gaussian Filter. One principle exploits that only a part of the state vector is directly observed by the measurement. The second principle separates the system equations into linear and nonlinear parts in order to merely approximate the nonlinear part of the state. The benefits of both decompositions are demonstrated on a real-world example.

description: We use the effective field theory for gravitational bound states, proposed by Goldberger and Rothstein, to compute the interaction Lagrangian of a binary system at the second Post-Newtonian order. Throughout the calculation, we use a metric parametrization based on a temporal Kaluza-Klein decomposition and test the claim by Kol and Smolkin that this parametrization provides important calculational advantages. We demonstrate how to use the effective field theory method efficiently in precision calculations, and we reproduce known results for the second Post-Newtonian order equations of motion in harmonic gauge in a straightforward manner.

Extension of the Sliced Gaussian Mixture Filter with Application to Cooperative Passive Target Tracking

description: This paper copes with the problem of nonlinear Bayesian state estimation. A nonlinear filter, the Sliced Gaussian Mixture Filter (SGMF), employs linear substructures in the nonlinear measurement and prediction model in order to simplify the estimation process. Here, a special density representation, the sliced Gaussian mixture density, is used to derive an exact solution of the Chapman-Kolmogorov equation. The sliced Gaussian mixture density is obtained by a systematic and deterministic approximation of a continuous density minimizing a certain distance measure. In contrast to previous work, improvements of the SGMF presented here include an extended system model and the processing of multi-dimensional nonlinear subspaces. As an application for the SGMF, cooperative passive target tracking, where sensors take angular measurements from a target, is considered in this paper. Finally, the performance of the proposed estimator is compared to the marginalized particle filter (MPF) in simulations.

description: It is shown that in the case of the forward scattering the most part of the difference between the Möbius form of the BFKL kernel and the BK kernel in the next-to-leading order (NLO) can be eliminated by the transformation related to the choice of the energy scale in the representation of scattering amplitudes. Change of the nonforward BFKL kernel under this transformation is derived as well. The functional identity of the forward BFKL kernel in the momentum and Möbius representations in the leading order (LO) is exhibited and its NLO validity in N=4 supersymmetric Yang-Mills theory is proved.

description: We present the first results from the largest deep extragalactic millimetre-wavelength survey undertaken to date. These results are derived from maps covering over 0.7 deg^2, made at 1.1mm, using the AzTEC continuum camera mounted on the James Clerk Maxwell Telescope. The maps were made in the two fields originally targeted at 0.85mm with SCUBA in the SHADES project, namely the Lockman Hole East (mapped to a depth of 0.9-1.3 mJy rms) and the Subaru XMM Deep Field (1.0-1.7 mJy rms). The wealth of existing and forthcoming deep multi-frequency data in these two fields will allow the bright mm source population revealed by these images to be explored in detail in subsequent papers. Here we present the maps themselves, a catalogue of 114 high-significance sub-millimetre galaxy detections, and a thorough statistical analysis leading to the most robust determination to date of the 1.1mm source number counts. Through careful comparison, we find that both the COSMOS and GOODS North fields, also imaged with AzTEC, contain an excess of mm sources over the new 1.1mm source-count baseline established here. In particular, our new AzTEC/SHADES results indicate that very luminous high-redshift dust enshrouded starbursts (S_{1.1} > 3 mJy) are 25-50% less common than would have been inferred from these smaller surveys, thus highlighting the potential roles of cosmic variance and clustering in such measurements. We compare number count predictions from recent models of the evolving mm/sub-mm source population to these SMG surveys, which provide important constraints for the ongoing refinement of semi-analytic and hydrodynamical models of galaxy formation, and find that all recent models over-predict the number of bright sub-millimetre galaxies found in this survey.

description: In the context of arithmetic surfaces, Bost defined a generalized Arithmetic Chow Group (ACG) using the Sobolev space L^2_1. We study the behavior of these groups under pull-back and push-forward and we prove a projection formula. We use these results to define an action of the Hecke operators on the ACG of modular curves and to show that they are self-adjoint with respect to the arithmetic intersection product. The decomposition of the ACG in eigencomponents which follows allows us to define new numerical invariants, which are refined versions of the self-intersection of the dualizing sheaf. Using the Gross-Zagier formula and a calculation due independently to Bost and Kuehn we compute these invariants in terms of special values of L series. On the other hand, we obtain a proof of the fact that Hecke correspondences acting on the Jacobian of the modular curves are self-adjoint with respect to the Néron-Tate height pairing.

Distributed Greedy Sensor Scheduling for Model-based Reconstruction of Space-Time Continuous Physical Phenomena
Creators: name: Huber, Marco F.
name: Kuwertz, Achim
name: Sawo, Felix
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: A novel distributed sensor scheduling method for large-scale sensor networks observing space-time continuous physical phenomena is introduced. In a first step, the model of the distributed phenomenon is spatially and temporally decomposed leading to a linear probabilistic finite-dimensional model. Based on this representation, the information gain of sensor measurements is evaluated by means of the so-called covariance reduction function. For this reward function, it is shown that the performance of the greedy sensor scheduling is at least half that of the optimal scheduling considering long-term effects. This finding is the key for distributed sensor scheduling, where a central processing unit or fusion center is unnecessary, and thus, scaling as well as reliability is ensured. Hence, greedy scheduling in combination with a proposed hierarchical communication scheme requires only local sensor information and communication.

description: We reinvestigate the photoproduction of the exotic pentaquark baryon Theta^+(1540,1/2^+) from the gamma N -> Kbar Theta^+ reaction process within the effective Lagrangian approach, taking into account new theoretical information on the K-N-Theta and K*-N-Theta coupling strengths from the chiral quark-soliton model (chiQSM). We also consider the crossing-symmetric hadronic form factor, satisfying the on-shell condition as well. Due to the sizable vector and tensor couplings for the vector kaon, g_{K* N Theta} and f_{K* N Theta}, which are almost the same with the vector coupling g_{K N Theta} ~ 0.8 for the pseudoscalar kaon, the K*-exchange contribution plays a critical role in the photon beam asymmetries.

description: At the onset of the RHIC era femtoscopic source sizes inferred from two-particle correlations at RHIC defied description with hydrodynamic models. This failure, which became known as the HBT puzzle, now appears to be solved. The source of the discrepancy appears to be a conspiracy of several factors, each of which contributed to making the evolution of RHIC collisions more explosive. These included pre-equilibrium flow, using a stiffer equation of state and adding viscosity.

Nonlinear Fusion of Multi-Dimensional Densities in Joint State Space
Creators: name: Klumpp, Vesa
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: Nonlinear fusion of multi-dimensional densities is an important application in Bayesian state estimation. In the approach proposed here, a joint density over all considered densities is build, which is then approximated by means of a Dirac mixture density by partitioning the joint state space into regions that are represented by single Dirac components. This approximation procedure depends on the nonlinear fusion model and only areas relevant to this model are considered. The processing in joint state space has advantages, especially when fusing Dirac mixture densities. Within this approach, degeneration can be avoided and even densities without mutual support can be combined. Thus, this approach gives an alternative to multiplication of Dirac mixtures with a likelihood, as used in the particle filter. Furthermore, a nonlinear Bayesian estimator with filter and prediction step can be formulated, which is able to cope with both discrete and continuous densities.

Spark ignition engine port air mass flow prediction using artificial neural networks
Creators: name: Jones, Nicholas R
Publisher: name: University Of Tasmania
Year: 2023

description: In order to maintain the air fuel ratio within the stoichiometric operating window, which is necessary for efficient catalytic converter operation an accurate estimation of the mass airflow at the engine ports is critical. It is difficult to accurately represent the port air mass flow of an Internal Combustion Spark Ignition engine as reciprocating engines are complex non-linear systems based on a large number of interrelated parameters. Conventional air fuel ratio control strategies use a number of three dimensional feedforward look up tables to represent these complex nonlinear engine functions. These look up tables are usually functions of only two engine variables, engine speed and engine load. Engine load is either, calculated from the speed density relationship using an absolute manifold air pressure sensor or measured directly using a mass air flow sensor. Conventional AFR control algorithms perform poorly during transient conditions as the strategies inherent in look up tables, are based on stationary or non-dynamic modelling techniques. Modern air fuel ratio control strategies employ a large number of correction factors to compensate for transient engine operation. This research is a preliminary investigation into the feasibility of using Artificial Neural Networks to represent transient nonlinear engine functions. This research develops offline artificial neural network models of the port air mass flow of a Spark Ignition, based on Hendricks' et al [1] accepted mean value engine model description of the manifold filling phenomena. In particular two different Artificial Neural Network paradigms, namely the Backpropagation algorithm and the fast converging Optimise Layer by Layer algorithm will be trained on data collected through both steady state and transient chassis dynamometer testing. Both steady state and transient air mass flow models will be developed in this investigation. The accuracy of the Backpropagation and Optimised Layer by Layer models will be analysed both qualitatively and quantitatively and compared in terms of the Root Mean Squared percentage error and computational time in an effort to evaluate the most appropriate model for future online engine implementation.

description: We analyze photometry of the Soft X-ray Transient A0620-00 spanning nearly 30 years, including previously published and previously unpublished data. Previous attempts to determine the inclination of A0620 using subsets of these data have yielded a wide range of measured values of i. Differences in the measured value of i have been due to changes in the shape of the light curve and uncertainty regarding the contamination from the disk. We give a new technique for estimating the disk fraction and find that disk light is significant in all light curves, even in the infrared. We also find that all changes in the shape and normalization of the light curve originate in a variable disk component. After accounting for this disk component, we find that all the data, including light curves of significantly different shapes, point to a consistent value of i. Combining results from many separate data sets, we find i=51 plus or minus 0.9 degrees, implying M=6.6 plus or minus 0.25 solar masses. Using our dynamical model and zero-disk stellar VIH magnitudes, we find d=1.06 plus or minus 0.12 kpc. Understanding the disk origin of non-ellipsoidal variability may assist with making reliable determinations of i in other systems, and the fluctuations in disk light may provide a new observational tool for understanding the three-dimensional structure of the accretion disk.

Study of selected factors affecting the communication process employed by general staff nurses in eight hospitals in referring patients with a long-term illness to the community setting
Creators: name: Taylor, Elizabeth Ann
Publisher: name: University of British Columbia
Year: 2011

description: This study was prompted by concern for the method of promoting continuity of care for persons discharged from hospital. Descriptive in design, the purpose of the study was to examine selected factors affecting the communication process employed between general staff nurses in hospitals: and personnel in community agencies with regard to the referral of patients with a long-term illness from the hospital to the community setting. The data were gathered by means of a self-administered questionnaire, designed to seek information related to each of the study's three hypotheses. It was completed by fifty-seven general staff nurses on selected nursing units of eight general hospitals in and near Vancouver, British Columbia. The units were chosen on the basis of the average number of patients with a long-term illness usually present on the unit. From analysis of the data the following conclusions were drawn. Although general staff nurses who participated in this study could recognize needs in patients which indicate the necessity for referral to community resources, they did not appear to have an adequate knowledge of available community agencies. When these nurses made referrals, the lines of communication used were frequently indirect.
Discovery of two distinct red clumps in NGC419: a rare snapshot of a cluster at the onset of degeneracy

description: Colour-magnitude diagrams (CMD) of the SMC star cluster NGC419, derived from HST/ACS data, reveal a well-delineated secondary clump located below the classical compact red clump typical of intermediate-age populations. We demonstrate that this feature belongs to the cluster itself, rather than to the underlying SMC field. Then, we use synthetic CMDs to show that it corresponds very well to the secondary clump predicted to appear as a result of He-ignition in stars just massive enough to avoid electron-degeneracy settling in their H-exhausted cores. The main red clump instead is made of the slightly less massive stars which passed through electron-degeneracy and ignited He at the tip of the RGB. In other words, NGC419 is the rare snapshot of a cluster while undergoing the fast transition from classical to degenerate H-exhausted cores. At this particular moment of a cluster's life, the colour distance between the main sequence turn-off and the red clump(s) depends sensitively on the amount of convective core overshooting, Lambda_c. By coupling measurements of this colour separation with fits to the red clump morphology, we are able to estimate simultaneously the cluster mean age (1.35(-0.04,+0.11) Gyr) and overshooting efficiency (Lambda_c=0.47(-0.04,+0.14)). Therefore, clusters like NGC419 may constitute important marks in the age scale of intermediate-age populations. After eye inspection of other CMDs derived from HST/ACS data, we suggest that the same secondary clump may also be present in the LMC clusters NGC1751, 1783, 1806, 1846, 1852, and 1917.

Bayesian Estimation with Uncertain Parameters of Probability Density Functions
Creators: name: Klumpp, Vesa

Publisher: name: Karlsruhe
Year: 2009

description: In this paper, we address the problem of processing imprecisely known probability density func- tions by means of Bayesian estimation. The imprecise knowledge about probability density functions is given as stochastic uncertainty about their parameters. The proposed processing of this special density in a Bayesian estimator is accomplished by reinterpretation of the Fil- ter and prediction equations. Here, the parameters are treated as a higher order state, which can be processed by Bayesian estimation techniques. For state estima- tion, this avoids the need to select specific values for unknown parameters and, thus, allows the processing of all potential parameters at once. The proposed approach further allows the use of imprecisely known model equa- tions for measurement and state prediction by the same principle.
The August 24, 2002 Coronal Mass Ejection: When a Western Limb Event Connects to Earth

description: We discuss how some coronal mass ejections (CMEs) originating from the western limb of the Sun are associated with space weather effects such as solar energetic particles (SEPs), shock or geo-effective ejecta at Earth. We focus on the August 24, 2002 coronal mass ejection, a fast (~ 2000 km/s) eruption originating from W81. Using a three-dimensional magneto-hydrodynamic simulation of this ejection with the Space Weather Modeling Framework (SWMF), we show how a realistic initiation mechanism enables us to study the deflection of the CME in the corona and the heliosphere. Reconnection of the erupting magnetic field with that of neighboring streamers and active regions modify the solar connectivity of the field lines connecting to Earth and can also partly explain the deflection of the eruption during the first tens of minutes. Comparing the results at 1 AU of our simulation with observations by the ACE spacecraft, we find that the simulated shock does not reach Earth, but has a maximum angular span of about 120$^\circ$, and reaches 35$^\circ$ West of Earth in 58 hours. We find no significant deflection of the CME and its associated shock wave in the heliosphere, and we discuss the consequences for the shock angular span.

Space charge effects on Landau damping from octupoles
Creators: name: Kornilov, V.
name: Boine-Frankenheim, O.
Publisher: name: CERN Yellow Reports: Conference Proceedings
Year: 2020

description: Octupole magnets are the cornerstone of the collective instability mitigation in many hadron synchrotrons, including the future SIS100 synchrotron of the FAIR project. The betatron tune shifts, and the tune spread, linearly increase with the octupole magnet current, and enhance Landau damping. On the other hand, a strong octupole field, as a nonlinearity, can reduce the dynamic aperture. This can put a restriction for the allowable octupole magnet power. Thus, a good understanding of the octupole magnet usage for Landau damping of the collective instabilities is important. The direct space-charge can produce comparable or stronger tune shifts than the octupoles. Thus the effects of space-charge should be taken into account in a study for Landau damping due to octupoles. Space-charge can have manifold effects on Landau damping. Space-charge can cause loss of Landau damping, it can provide Landau damping, it changes the incoherent tune distribution and thus changes Landau damping in the beam. The bunched beams are considered in this work, with the focus on the head-tail instability. Head-tail modes are eigenmodes of the transverse collective bunch oscillations. Unstable head-tail modes are a major concern for high-intensity operation in ring accelerators. We consider unstable head-tail modes with different mode indices k, with the non-rigid bunch oscillations due to a finite chromaticity, even the lowest-order mode k = 0. In the next section we review some properties of Landau damping in coasting beams and in bunches, the effects of octupoles and space-charge. For this discussion we consider two dispersion relations. The particle tracking simulations and the stability study method are described, followed by the results for the beam stability due to octupoles with space-charge of different strength. The results and the conclusions are discussed with the consideration of the incoherent tune distributions.

Intention Recognition for Partial-Order Plans Using Dynamic Bayesian Networks
Creators: name: Krauthausen, Peter
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: In this paper, a novel probabilistic approach to intention recognition for partial-order plans is proposed. The key idea is to exploit independences between subplans to substantially reduce the state space sizes in the compiled Dynamic Bayesian Networks. This makes inference more efficient. The main con- tributions are the computationally exploitable definition of subplan structures, the introduction of a novel Lay- ered Intention Model and a Dynamic Bayesian Net- work representation with an inference mechanism that exploits consecutive and concurrent subplans' indepen- dences. The presented approach reduces the state space to the order of the most complex subplan and requires only minor changes in the standard inference mecha- nism. The practicability of this approach is demon- strated by recognizing the process of shelf-assembly.

State Estimation with Sets of Densities considering Stochastic and Systematic Errors
Creators: name: Noack, Benjamin
name: Klumpp, Vesa
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2009

description: In practical applications, state estimation requires the consideration of stochastic and systematic errors. If both error types are present, an exact probabilistic description of the state estimate is not possible, so that common Bayesian estimators have to be questioned. This paper introduces a theoretical concept, which allows for incorporating unknown but bounded errors into a Bayesian inference scheme by utilizing sets of densities. In order to derive a tractable estimator, the Kalman filter is applied to ellipsoidal sets of means, which are used to bound additive systematic errors. Also, an extension to nonlinear system and observation models with ellipsoidal error bounds is presented. The derived estimator is motivated by means of two example applications.
St. Michaels language unit : a ten year study, 1977-1986
Creators: name: Merrington, Pamela
Publisher: name: University Of Tasmania
Year: 2023

description: This is a longitudinal survey of 10 children chosen from a total group of 53 who attended St. Michaels Language Unit (for pre-school age language disordered children) at some time during the ten year period between 1977 and 1986. Interviews have been conducted with each child, the child's parents, teachers and the school principal. Relatively similar patterns emerge. It has been found that most of the students can be integrated into mainstream classes and families are generally happy with the child's attendance at a regular school. It is common, however for the children to be characterized by oral communication, reading, writing and spelling difficulties and by ineffective social communication skills. Most children continue to require careful monitoring and remediation throughout their school days. As young adults they generally lead happy and productive lives (usually in employment) although presenting as 'a little slow' . Without a control group, it is difficult to judge the relative success of students who have had experience in the Language Unit. The performance of these students is described along with British provisions which are similar and also lead to longitudinal studies. Opportunity exists for further research study.

description: The asymptotic discrimination problem of two quantum states is studied in the setting where measurements are required to be invariant under some symmetry group of the system. We consider various asymptotic error exponents in connection with the problems of the Chernoff bound, the Hoeffding bound and Stein's lemma, and derive bounds on these quantities in terms of their corresponding statistical distance measures. A special emphasis is put on the comparison of the performances of group-invariant and unrestricted measurements.

description: The purpose of this paper is to introduce the Ricci Yang-Mills soliton equations on nilpotent Lie groups. In the 2-step nilpotent setting, we show that these equations are strictly weaker than the Ricci soliton equations. Using techniques from Geometric Invariant Theory, we develop a procedure to build many different kinds of Ricci Yang-Mills solitons. We finish this note by producing examples of Lie groups that do not admit Ricci soliton metrics but that do admit Ricci Yang-Mills soliton metrics.
