Inertial navigation system assisted visual localization
Creators: name: Krys, Dennis
Publisher: name: University of British Columbia
Year: 2011

description: With recent advancements in Global Positioning Systems (GPS), localization systems are now typically equipped with a GPS. However, in a large variety of environments and real-world applications, GPS-based localization systems are not practical. This research tackles such a problem and illustrates the idea of fusing a camera and an inertial navigation system (INS) to create a dead reckoning localization system. The original purpose of the localization system is for a pipe inspection robot, but the proposed concepts can be readily applied to any environment where there is a wall in close proximity. The proposed sensor system can determine motions with up to six degrees of freedom using a camera and an INS. The system must assume a geometry for the wall, such as a at surface, a wall in a hallway, or the round surface of the inside of a pipe. If the geometry of the wall is unknown then another sensor, such as a laser range nder, can be added to measure the range and estimate the overall shape of the wall. The localization system uses a combination of optical ow and image registration to obtain information about six degrees of freedom from a wall with little to no features. The INS provides an estimated motion for the camera system. The estimation of the motion is used by the optical ow algorithm to reduce the computational load signi cantly and by the image registration to decrease the likelihood of the algorithm diverging. The system is validated using numerical simulation and experiments. The experiments were conducted on a test platform constructed speci cally in this research project to simulate the motion of a free-swimming robot inside a pipe. The simulator uses accurate ii position sensors to measure the exact location of the proposed localization system and compare it with the results obtained from the latter. Both the numerical simulation results and the results from the simulator are in agreement with reading of the localization system developed in this research.

Subjects: Computer science

description: LPS is a Logic Programming System currently under development and specially targeted for implementation on massively parallel architectures. We present a detailed explanation of algorithms under development for parallel execution of LPS programs. The explanation is significantly more detailed then those published previously. An abstract proof procedure is developed which encompasses these algorithms and several variants, as well as the standard sequential Prolog algorithm. This abstract procedure provides a conceptual basis for our discussion and for a critical analysis of various execution strategies. The algorithms have been successfully implemented and demonstrated in simulation on a number of small programs. Work is currently underway to transfer this implementation to a working prototype machine based on the DADO parallel architecture.
Data governance in the dairy sector in Croatia

Subjects: farm data privacy

description: World milk production is increasing rapidly (59 % since 1988), mainly due to the increase in the number of producing animals, with developing countries increasing their share. The increase in productivity per head is limited and focused predominantly on cow milk (81 % of total world milk) in the EU (top producer and exporter in 2020) and the US. The professional skills important for a dairy farm are shifting from manual management of the man-animal-machine interface to management using data from digitized automated (robotic) milking and dairy systems. Our aim was to provide an overview of opportunities and requirements for dairy data governance in Croatia by examining existing examples worldwide. With the transition to digital agriculture, dairy production has great prospects to increase efficiency of milk production through better and sustainable management of feed resources, control of diseases, access to markets and services (e.g. health, finance and training), and planning sustainable production in adequate climate for specific species and breeds. The greatest impact is expected for small dairy farmers in countries such as Croatia. Current regulations ("Code of Conduct on Agricultural Data") and the declaration of cooperation "A smart and sustainable digital future for European agriculture and rural areas") are voluntary and can only serve as guidelines for formal contractual agreements. However, data sharing contracts generate limited trust and require additional tools to encourage farmers to participate in the data economy, as agribusinesses (i.e. digital experts) differ from farmers (i.e. non-digital experts) in terms of expertise and knowledge. The challenges posed by the increasing availability of farm level data and the collection, aggregation, anonymization, and analysis of data need to be mitigated by a set of national standards that ensure the security, integrity, and efficiency of data storage and access (data governance). Possible solutions emphasize several key points: (i) milk producers own the data generated on their own farms ; (ii) data security and transparency are essential, but only together with an opt-out option in the contract ; (iii) an optimal method is needed to incentivize farmers to feel comfortable with sharing their data ; (iv) the idea of the concept should be adopted by other farm industries and serve as a good guideline for other countries.

description: Although a precise description of microscopic physical problems requires a full quantum mechanical treatment, physical quantities are generally discussed in terms of classical variables. One exception is quantum entanglement which apparently has no classical counterpart. We demonstrate here how quantum entanglement may be within the de Broglie-Bohm interpretation of quantum mechanics visualized in geometrical terms, giving new insight into this mysterious phenomenon and a language to describe it. On the basis of our analysis of the dynamics of a pair of qubits, quantum entanglement is linked to concurrent motion of angular momenta in the Bohmian space of hidden variables and to the average angle between these momenta.

description: (Context.) A number of millimeter and submillimeter facilities with linear polarization observing capabilities have started operating during last years. These facilities, as well as other previous millimeter telescopes and interferometers, require bright and stable linear polarization calibrators to calibrate new instruments and to monitor their instrumental polarization. The current limited number of adequate calibrators implies difficulties in the acquisition of these calibration observations. (Aims.) Looking for additional linear polarization calibrators in the millimeter spectral range, in mid-2006 we started monitoring 3C 286, a standard and highly stable polarization calibrator for radio observations. (Methods.) Here we present the 3 and 1 mm monitoring observations obtained between September 2006 and January 2012 with the XPOL polarimeter on the IRAM 30 m Millimeter Telescope. (Results.) Our observations show that 3C 286 is a bright source of constant total flux with 3 mm flux density S_3mm = (0.91 \pm 0.02) Jy. The 3mm linear polarization degree (p_3mm =[13.5\pm0.3]%) and polarization angle (chi_3mm =[37.3\pm0.8]deg.,expressed in the equatorial coordinate system) are also constant during the time span of our observations. Although with poorer time sampling and signal-to-noise ratio, our 1 mm observations of 3C 286 are also reproduced by a constant source of 1 mm flux density (S_1mm = [0.30 \pm 0.03] Jy), polarization fraction (p_1mm = [14.4 \pm 1.8] %), and polarization angle (chi_1mm = [33.1 \pm 5.7]deg.). (Conclusions.) This, together with the previously known compact structure of 3C 286 -extended by ~3.5" in the sky- allow us to propose 3C 286 as a new calibrator for both single dish and interferometric polarization observations at 3 mm, and possibly at shorter wavelengths.

Public and health professional opposition to community water fluoridation: An investigation of trust and perceived risk in the context of new, local research findings

subject: Community water fluoridation
subject: Public Health

description: Background: Community water fluoridation (CWF) has remained a highly-debated topic among the public since it was introduced in 1945. Since then, several studies have provided support for the safety and effectiveness of CWF, although there are limitations to both the quantity and quality of the current evidence base. Despite the available scientific data, there exists a divide on public views toward CWF. Purpose: The purpose of this study was to understand how health professionals and members of the public in Calgary, who self-identify as opposed to CWF, make sense of locally-relevant and recent research evidence on fluoridation cessation and tooth decay in the city of Calgary. I sought to gain insights into fluoridation specifically and public health initiatives more generally. Methods: I undertook a critical qualitative study, informed by theories of risk perception and trust in authority figures and the scientific community. Four health professionals were purposively recruited to participate in one-on-one interviews based on their self-identified opposition to CWF. Participants were asked to discuss their views on CWF and public health research in general, with a focus on publications from a study of the short-term implications for children’s dental caries of terminating CWF in Calgary in 2011. To supplement interview responses, I analyzed online comments pertaining to the Calgary fluoridation cessation study. Results: Overall, I observed three prominent and overlapping themes: (1) Fluoridation research criticisms, which describes criticisms and negative comments from interviewees and online commenters about the Calgary fluoridation study specifically, and fluoridation research in general. (2) Selective Mistrust expressed by interviewees and online commenters toward the Calgary fluoridation cessation study, health research, and researchers, and (3) the Individualization of health, wherein interviewees and online commenters were skeptical toward health and government authority figures and their ability to make appropriate health decisions for the public, which led to the perception that the responsibility for oral health lies with the individual. Conclusions: With the publication of local research on fluoridation cessation, this study provided a ‘real time’ opportunity to gain a contemporary, nuanced understanding of what characterizes fluoridation opposition among some health professionals and members of the public.

Surface Orientation from Texture Autocorrelation
Creators: name: Brown, Lisa Gottesfeld
Publisher: name: Columbia University
Year: 1989
Subjects: Computer science

description: We report on a refinement of our technique for determining the orientation of a textured surface from the two-point autocorrelation function of its image. We replace our previous assumptions of isotropic texture by knowledge of the autocorrelation moment matrix of the texture when viewed head on. The orientation of a textured surface is then deduced from the effects of foreshortening on these autocorrelation moments. This technique is applied to natural images of planar textured surfaces and gives significantly improved results when applied to anisotropic textures which under the assumption of isotropy mimic the effects of projective foreshortening. The potential practicality of this method for higher level image understanding systems is discussed.

description: An operating system (OS) maps a model of computation, defined by its kernel interface, onto the underlying hardware. A. simple and intuitive model of computation makes it easy for programmers to write applications. An efficient implementation of the mapping makes the applications run fast. Typical OS interfaces for von Neumann hardware include processes (CPU), address spaces (memory), and I/O devices (I/O). An OS for distributed and multiprocessor systems must support parallel processing and inter-process communications. Designed for the distributed and multiprocessor systems of today and tomorrow, Synthesis is an example of the new generation of OS's. The Synthesis model of computation based on macro dataflow makes parallel programming easy. The Synthesis implementation uses innovative ideas from areas as different as compilers and control systems, Kernel Code Synthesis. Reduced Synchronization, Fine-Grain Scheduling, and Valued Redundancy provide high performance. Emulation of guest OS's in Synthesis allow existing software written for other OS's to run on Synthesis with little or no modification. Using hardware and software emulating a SUN-3/160 running SUN OS, the current version of Synthesis kernel achieves several times to several dozen times speed up for UNIX kernel calls.
An Algorithm to Recover Generalized Cylinders from a Single Intensity View

description: Understanding a scene involves the ability to recover the shape of objects in an environment. Generalized cylinders are a flexible, loosely defined class of parametric shapes capable of modeling many real-world objects. Straight homogeneous generalized cylinders are an important subclass of generalized cylinders whose cross sections are scaled versions of a reference curve. In this paper, a general method is presented for recovering straight homogeneous generalized cylinders from monocular intensity images. The algorithm is much more general in scope than any other developed to date. combining constraints derived from both contour and intensity information. We first demonstrate that contour information alone is insufficient to recover a straight homogeneous generalized cylinder uniquely. Next, we show that the sign and magnitude of the Gaussian curvature at a point varies among members of a contour-equivalent class. The image contour fails to constrain two parameters required to recover the shape of a generalized cylinder, the 3D axis location and the object tilt. Next, a method for "ruling" straight homogeneous generalized cylinder images is developed. Once the rulings of the image have been recovered, we show that all parameters derivable from contour alone can be recovered. To recover the two remaining parameters (modulo scale) not constrained by image contour requires incorporating additional information into the recovery process, e.g. intensity information. We derive a method for recovering the tilt of the object using the ruled contour image and intensity values along cross-sectional geodesics. In addition, we derive a method for recovering the location of the object's 3D axis from intensity values along meridians of the surface. Using the different methods outlined in this paper constitutes an algorithm for recovering all the shape parameters (modulo scale) of a straight homogeneous generalized cylinder.
Mothers—the New Hidden Reserve? Germany and the U.S., a Comparison

description: Do economic recessions change the labor market attachment of women with children? How is the reentry process after childbirth dependent on the welfare state regime that mothers have to negotiate? We use data from the NLSY and the German Life History Study to test the effects of parental leave and unemployment rates for changes in mothers‘ rate of return to employment after the birth of a child. We introduce and test two types of hypotheses of mothers‘ employment continuity after birth, the "new hidden reserve" hypothesis and the "agency" hypothesis. In western Germany it is mothers on parental leave who appear to constitute a modern, institutionally fostered "new hidden reserve." These mothers tend to return to their jobs later when unemployment is high. In the U.S., occupational prestige is a significant factor in supplying "agency" to mothers during economically tied situations. However, here, economic recessions come with increasing employment gaps, especially for mothers with lower socio-economic status.

description: An algorithm is presented which provides an optimal solution to the problem of scheduling non-relocatable time intervals of bandwidth in differentiated services networks. Simulations found an asymmetry between valuing an interval’s length and bandwidth requirement. Longer intervals requiring less resource are favored over shorter intervals requiring more resource. The optimal algorithm is shown to respond appropriately to price as a mechanism of control whereas the offline greedy and the online FCFS algorithms do not. The solution uses integer programming, and it is shown that, except in the general case, the problem can be solved in polynomial time.

description: The authors have previously described the use of data path expressions and predecessor automata in debugging concurrent systems. In this paper we examine the relationship of these models to two traditional models of concurrent processes: pomset languages and k-safe Petri net systems. We explore the regularity and safety of the concurrent languages described by each of the four models. Our main result is the equivalence of regular safe pomset languages and the languages described by safe data path expressions, safe predecessor automata and k-safe Petri net systems.

Teaching for social justice in the high school Spanish classroom : perspectives and practices
Creators: name: Benson, Nicole
Publisher: name: University of British Columbia
Year: 2011

description: Talk of social justice is increasingly common in the educational context of British Columbia as well as in the academic literature on education. However, specific examples of how teachers of subjects other than English and Social Studies are taking up a social justice discourse are sparse. Specifically, there is very little written on such approaches to teaching Spanish as an additional language. This exploratory research therefore aimed to understand the extent to which high school Spanish teachers in British Columbia are incorporating social justice education into their pedagogies and curricula. Through online questionnaires sent to Spanish teachers across the province, interviews with seven of these teachers, and four sets of classroom observations, the study explored perspectives on social justice education, classroom practices that evidenced a commitment to such pedagogy, and the perceived obstacles to teaching for social justice in the high school Spanish classroom. It was found that teachers espoused a variety of definitions of social justice education but that the overwhelming majority believed in the importance of such approaches in the Spanish classroom. They evidenced an inspiring array of practices aimed at promoting social justice that could be seen as either educating about social justice, through curricula and classroom discussions, or for social justice, through democratic and anti-oppressive methodologies. It was found that many of these practices could serve to counter each of the five faces of oppression described by Young (1990): exploitation, marginalization, powerlessness, cultural imperialism, and violence. Unfortunately, many obstacles to social justice education were also noted, including a lack of support and resources. This study demonstrates that there is a strong interest in bringing social justice education into the high school Spanish classroom but that more must be done to support teachers in this endeavour.

description: Geometric frustration is a broad phenomenon that results from an intrinsic incompatibility between some fundamental interactions and the underlying lattice geometry1-7. Geometric frustration gives rise to new fundamental phenomena and is known to yield intriguing effects, such as the formation of exotic states like spin ice, spin liquids and spin glasses1-7. It has also led to interesting findings of fractional charge quantization and magnetic monopoles5,6. Geometric frustration related mechanisms have been proposed to understand the origins of relaxor behavior in some multiferroics, colossal magnetocapacitive coupling and unusual and novel mechanisms of high Tc superconductivity1-5. Although geometric frustration has been particularly well studied in magnetic systems in the last 20 years or so, its manifestation in the important class formed by ferroelectric materials (that are compounds exhibiting electric rather than magnetic dipoles) is basically unknown. Here, we show, via the use of a first-principles-based technique, that compositionally graded ferroelectrics possess the characteristic "fingerprints" associated with geometric frustration. These systems have a highly degenerate energy surface and exhibit original critical phenomena. They further reveal exotic orderings with novel stripe phases involving complex spatial organization. These stripes display spiral states, topological defects and curvature. Compositionally graded ferroelectrics can thus be considered as the "missing" link that brings ferroelectrics into the broad category of materials able to exhibit geometric frustration. Our ab-initio calculations allow a deep microscopic insight into this novel geometrically frustrated system.

description: This is a proceeding of the CERN Latin American School of High-Energy physics that took place in the beautiful city of Natal, northern Brazil, in March 2011. In this paper I present a review of the main topics associated with the study of Heavy Ion Collisions, intended for students starting or interested in the field. It is impossible to summarize in a few pages the large amount of information that is available today, after a decade of operations of the RHIC accelerator and the beginning of the LHC operations. Thus, I had to choose some of the results and theories in order to present the main ideas and goals. All results presented here are from publicly available references, but some of the discussions and opinions are my personal view, where I have made that clear in the text.

Modeling Concurrency in Parallel Debugging
Creators: name: Hseush, Wenwey

Publisher: name: Columbia University

Subjects: Computer science

description: We propose a description language, Data Path Expressions (DPEs), for modeling the behavior of parallel programs. We have designed DPEs as a high-level debugging language, where the debugging paradigm is for the programmer to describe the expected program behavior and for the debugger to compare the actual program behavior during execution to detect program errors. We classify DPEs into five subclasses according to syntactic criteria, and characterize their semantics in terms of a hierarchy of extended Petri Net models. The characterization demonstrates the power of DPEs for modeling (true) concurrency. We also present predecessor automata as a mechanism for implementing the third subclass of DPEs, which expresses bounded parallelism. Predecessor automata extend finite state automata to recognize or generate partial ordering graphs as well as strings, and provide efficient event recognizers for parallel debugging. We briefly describe the application of DPEs race conditions, deadlock and starvation.

Robot Active Touch Exploration: Constraints and Strategies
Creators: name: Roberts, Kenneth S.
Publisher: name: Columbia University
Year: 1989
Subjects: Computer science

description: We investigate the problem of using active touch ("haptic") exploration to recognize a 3D object taken from a known set of models. "That is new is that we combine two approaches: (1) using geometric constraints between components to eliminate interpretations, and interpretation tree methods for choosing the best active sensing move; (2) exploratory moves made by tracing continually along the surface of the object (and not through free space). We restrict ourselves to polyhedral, and give a set of geometric constraints tailored for matching components acquired from haptic exploration against components in the models. We present a new constraint using pairs of line segments. We then give a set of active sensing moves, each with an associated cost measure, and our strategies for choosing the next move.
Localization on Smartphones Using Visual Fingerprinting

description: Many people nowadays can benefit from localization since the ubiquitous smartphones are integrated with many facilities such as visual sensors which can provide absolute or relative localization. Visual Fingerprinting (VFP) is an image matching technique which is based on visual information and provides localization to the user by finding the closest images in the database of images or videos. This approach has the flexibility to compensate between the accuracy and the practical implementation requirements. VFP especially becomes an attractive localization solution for the urban indoor environment due to certain number of facts such as limited access to the GNSS signals, the abundance of visually recognizable and distinguishable features in these environments, and that it does not require device calibration. Most VFP methods that are developed to be implemented on the smartphones include integration with other sensors such as Wi-Fi. These methods are focused mostly on the accuracy and less so on the computational aspects. They usually do not provide a detailed analysis that would suggest the feasibility of real-time implementation of their methods on smartphones. This study investigates the effectiveness of different VFP methods by evaluating the accuracy of the matching, preprocessing time and average matching time. To perform VFP, several things are required; a database of the location-tagged images, an algorithm to process the uploaded images; an algorithm to find the match in the image database and a localization algorithm that infers a location for the user based on the aforementioned steps. This research is focused on the first three steps. Explicitly the local detectors and descriptors have been used and their important properties have been studied. To further enhance the performance, multi-dimensional data structure has been deliberated. Consequently, a set of different combination for detectors/descriptors, data structures and dimensionality reduction algorithm has been chosen to be evaluated. The results obtained from the evaluations show that with the proper selection between these combinations, they can deliver the practical requirements to implement VFP-based localization on smartphones.
Estimating the Largest Eigenvalue by the Power and Lanczos Algorithms with a Random Start

Subjects: Computer science

description: This paper addresses the problem of computing an approximation to the largest eigenvalue of an n x n large symmetric positive definite matrix with relative error at most ε. Only algorithms that use Krylov information [b, Ab, . .. , Akb] consisting of k matrix-vector multiplications for some unit vector b are considered. If the vector b is chosen deterministically, then the problem cannot be solved no matter how many matrix-vector multiplications are performed and what algorithm is used. If, however, the vector b is chosen randomly with respect to the uniform distribution over the unit sphere, then the problem can be solved on the average and probabilistically. More precisely, for a randomly chosen vector b, the power and Lanczos algorithms are studied. For the power algorithm (method), sharp bounds on the average relative error and on the probabilistic relative failure are proven. For the Lanczos algorithm only upper bounds are presented. In particular, ln ( n )/k characterizes the average relative error of the power algorithm, whereas O( ( ln ( n )/ k )2 ) is an upper bound on the average relative error of the Lanczos algorithm. In the probabilistic case, the algorithm is characterized by its probabilistic relative failure, which is defined as the measure of the set of vectors b for which the algorithm fails. It is shown that the probabilistic relative failure goes to zero roughly as sqrt n (1 - ε) ^k for the power algorithm and at most as sqrt n e^{ - (2k - 1)\sqrt ε } for the Lanczos algorithm. These bounds are for a worst case distribution of eigenvalues which may depend on k. The behavior in the average and probabilistic cases of the two algorithms for a fixed matrix A is also studied as the number of matrix-vector multiplications k increases. The bounds for the power algorithm depend then on the ratio of the two largest eigenvalues and their multiplicities. The bounds for the Lanczos algorithm depend on the ratio between the difference of the two largest eigenvalues and the difference of the largest and the smallest eigenvalues.

description: We consider the ATLAS and CMS searches for dijet resonances, as well as the ATLAS search for like-sign dimuon pairs at the LHC with 7 TeV center of mass energy. We interpret their exclusions in terms of bounds on the supersymmetric R-parity violating parameter space. For this we focus on resonant slepton production followed by the corresponding decay.

An effective gluon potential and hybrid approach to Yang-Mills thermodynamics

description: We derive the partition function for the SU(3) Yang-Mills theory in the presence of a uniform gluon field within the background field method. We show, that the $n$-body gluon contributions in the partition function are characterized solely by the Polyakov loop. We express the effective action through characters of different representations of the color gauge group resulting in a form deduced in the strong-coupling expansion. A striking feature of this potential is that at low temperature gluons are physically disfavored and therefore they do not yield the correct thermodynamics. We suggest a hybrid approach to Yang-Mills thermodynamics, combining the effective gluon potential with glueballs implemented as dilaton fields.
