description: With the fast advancements of the Autonomous Vehicle (AV) industry, detection of Vulnerable Road Users (VRUs) using smartphones is critical for safety applications of Cooperative Intelligent Transportation Systems (C-ITSs). This study explores the use of low-power smartphone sensors and the Recurrence Quantification Analysis (RQA) features for this task. These features are computed over a thresholded similarity matrix extracted from nine channels: accelerometer, gyroscope, and rotation vector in each direction (x, y, and z). Given the high-power consumption of GPS, GPS data is excluded. RQA features are added to traditional time domain features to investigate the classification accuracy when using binary, four-class, and five-class Random Forest classifiers. Experimental results show a promising performance when only using RQA features with a resulted accuracy of 98. 34% and a 98. 79% by adding time domain features. Results outperform previous reported accuracy, demonstrating that RQA features have high classifying capability with respect to VRU detection.

description: We consider a classical test particle subject to electromagnetic and gravitational fields, described by a Lagrangian depending on the acceleration and on a fundamental length. We associate to the particle a moving local reference frame and we study its trajectory in the principal fibre bundle of all the Lorentz frames. We discuss in this framework the general form of the Lagrange equations and the connection between symmetries and conservation laws (Noether theorem). We apply these results to a model, already discussed by other authors, which implies an upper bound to the proper acceleration and to another new model in which a similar quantity, called ``pseudo-acceleration'', is bounded. With some simple choices of the fields, we illustrate some other interesting properties of the models and we show that unwanted features may appear, as unstable run-away solutions and unphysical values of the energy-momentum or of the velocity.

description: The strong-field approximation can be and has been applied in both length gauge and velocity gauge with quantitatively conflicting answers. For ionization of negative ions with a ground state of odd parity, the predictions of the two gauges differ qualitatively: in the envelope of the angular-resolved energy spectrum, dips in one gauge correspond to humps in the other. We show that the length-gauge SFA matches the exact numerical solution of the time-dependent Schrödinger equation.

description: The process of planning and budgeting for public institutions has been a topic of recent interest as budgetary constraints have mandated reduced funding for state agencies and publicly funded educational institutions. The most recent budget outlook in Minnesota suggests that funding for the University of Minnesota will be reduced significantly in the next biennium. This outlook is renewing the call for increased efficiency and cost control for publicly funded educational institutions such as the University of Minnesota. The authors have been involved with a project in which cost functions and economic relationships were examined within the College of Agricultural, Food and Environmental Sciences at the University of Minnesota. This paper is an extension of these efforts and attempts to address the questions relating to instructional revenue sharing.

description: A two stage model describes the behavior of anglers who fish with or without a license. The proposed multinomial logit-count data model examines characteristics influencing those who fish for recreation and those who may choose to fish to supplement their food budgets. The model is estimated using data from the national survey. Results show, among others, that anglers who fish to supplement their diet are more likely to come from households run by women, with less income and were less educated than those who fished for recreational purposes.

description: This paper develops a novel two-layer hierarchical classifier that increases the accuracy of traditional transportation mode classification algorithms. This paper also enhances classification accuracy by extracting new frequency domain features. Many researchers have obtained these features from global positioning system data; however, this data was excluded in this paper, as the system use might deplete the smartphone's battery and signals may be lost in some areas. Our proposed two-layer framework differs from previous classification attempts in three distinct ways: 1) the outputs of the two layers are combined using Bayes' rule to choose the transportation mode with the largest posterior probability; 2) the proposed framework combines the new extracted features with traditionally used time domain features to create a pool of features; and 3) a different subset of extracted features is used in each layer based on the classified modes. Several machine learning techniques were used, including k-nearest neighbor, classification and regression tree, support vector machine, random forest, and a heterogeneous framework of random forest and support vector machine. Results show that the classification accuracy of the proposed framework outperforms traditional approaches. Transforming the time domain features to the frequency domain also adds new features in a new space and provides more control on the loss of information. Consequently, combining the time domain and the frequency domain features in a large pool and then choosing the best subset results in higher accuracy than using either domain alone. The proposed two-layer classifier obtained a maximum classification accuracy of 97.02%.

description: We derive the general form of the cosmological scalar field potential which is compatible both with the existence of black holes and p-branes related to string/M theory and with multidimensional inflationary cosmology. It is shown that the scalar potential alters non-trivially from dimension to dimension yet always obeys one single equation where the number of spacetime dimensions is a free parameter. Using this equation we formulate an eigenvalue problem for the dimensionality parameter. It turns out that in the low-energy regime of sub-Planckian values of the inflaton field, i.e., when the Universe has cooled and expanded sufficiently enough, the value four arises as the largest admissible (eigen)value of this parameter.

description: It was conjectured by H. Zassenhaus that a torsion unit of an integral group ring of a finite group is conjugate to a group element within the rational group algebra. The object of this note is the computational aspect of a method developed by I.S. Luthar and I.B.S. Passi which sometimes permits an answer to this conjecture. We illustrate the method on certain explicit examples. We prove with additional arguments that the conjecture is valid for any 3-dimensional crystallographic point group. Finally we apply the method to generic character tables and establish a p-variation of the conjecture for the simple groups PSL(2,p).

description: Faced with the task of reorganizing the largest agricultural research system in the world, officials in China are developing a strategy for reform. This paper investigates economies of scale and scope and other potential sources of improvements in the economic efficiency of crop breeding, an industry at the heart of the nation's food economy. Using a panel data set covering 46 wheat and maize breeding institutes from 1981 to 2000, we estimate both single output and multiple output cost functions for the production of new varieties at China's wheat and maize breeding institutes. Our descriptive and analytical results indicate strong economies of scale, along with small to moderate economies of scope related to the joint production of new wheat and maize varieties. Cost efficiency increases significantly with increases in the breeders' educational status and with increases in access to genetic materials from outside the institute. Our results can help guide reformers in their efforts to increase the efficiency of China's crop breeding system.

description: We determine the quantization condition for the energy levels of two interacting particles in a finite box in a ``moving frame'', i.e. one in which the total momentum of pions is non-zero. This condition is valid up to corrections which fall exponentially withe the box size, and holds only below the inelastic threshold. It is derived using field theoretic methods, using a generalization of previous summation formulae relating sums and integrals over momenta. The result agrees with that obtained earlier by Rummakainen and Gottlieb using a relativistic quantum mechanical approach. Technically, we expand the finite-volume four-point Green function in terms of the infinite-volume Bethe-Salpeter kernel, and determine the position of the poles. The final result is written in terms of the two-pion scattering phase shift. Our result can be used to facilitate the determination of the scattering phase shift, and can be used to generalize the Lellouch-Lüscher formula relating finite-volume two-particle matrix elements to those in infinite volume.

description: The potentially adverse effects of pesticides in wide use are causing concern to grow in the agricultural community. Minimizing the risks to human health and the environment created by agricultural pesticides has become a very important issue. The United States Environmental Protection Agency (EPA) has set a high priority on registering safer pesticides. According to the EPA, more than 1 billion pounds of active pesticide ingredients are used in the United States each year. Americans are exposed to pesticides every day through food consumption, cleaning products, and home and work environments. The agricultural pesticide industry has experienced an influx of changes during the past decade. Two of the primary changes affecting the pesticide industry are the introduction of new technology and EPA regulatory changes. On the regulatory front, the EPA requires manufacturers to register and test pesticides before they appear on the market. By 2006, the EPA will review old pesticides to ensure that they meet new safety requirements. These regulatory initiatives have contributed to the industry drive to develop safer and more "environmentally friendly" products for use in agricultural pest control. Technological changes consist of the introduction of new pesticides that are considered to be safer for both humans and the environment. As new technologies and regulatory initiatives are undertaken to ensure an improvement in both the safety of human health and the environment, one must consider how these changes may affect consumers. Specifically, an analysis should be conducted to determine whether or not the technological and regulatory changes have an effect on consumer prices. The recent developments in the agricultural pesticide industry provide several reasons to believe structural change has been occurring in economic relationships that determine peach prices in California. Therefore, we use a vector autoregressive (VAR) model to forecast peach prices by allowing parameters to vary with time. VAR models differ from standard econometric analyses of structural relationships in that they do not apply the usual exclusion restrictions to specify a priori which variables appear in which equations. Instead, a set of distributed lag equations is used to model each variable as a function of other variables in the structural system (Bessler, 1984). The objective of this paper is to forecast peach prices and evaluate dynamic relationships in the peach industry in the presence of technological and regulatory change. A VAR model that explicitly recognizes structural change will be used to forecast peach prices in California. Changes in dynamic relationships between peach prices and relevant economic variables will be considered.

description: Sluggish growth in per capita consumption and a downward pressure on beef price at the farm level has required producers to raise cattle that precisely target the meat attributes desired by consumers. Ultrasound technology can help farmers to produce a carcass with an optimal mix of marbling and muscling, and external fat. The results of this study show a high level of accuracy of ultrasound technology in predicting carcass attributes. An estimated hedonic regression model shows that the carcass attributes are reflected on the implicit beef price. Ultrasound technology helps producers to produce carcass with the desired attributes, thus obtain a higher price.

description: Aims: We aim at constraining the conditions of the wind and high-energy emission of the host star reproducing the non-detection of Ly$α$ planetary absorption. Methods: We model the escaping planetary atmosphere, the stellar wind, and their interaction employing a multi-fluid, three-dimensional hydrodynamic code. We assume a planetary atmosphere composed of hydrogen and helium. We run models varying the stellar high-energy emission and stellar mass-loss rate, further computing for each case the Ly$α$ synthetic planetary atmospheric absorption and comparing it with the observations. Results: We find that a non-detection of Ly$α$ in absorption employing the stellar high-energy emission estimated from far-ultraviolet and X-ray data requires a stellar wind with a stellar mass-loss rate about six times lower than solar. This result is a consequence of the fact that, for $π$ Men c, detectable Ly$α$ absorption can be caused exclusively by energetic neutral atoms, which become more abundant with increasing the velocity and/or the density of the stellar wind. By considering, instead, that the star has a solar-like wind, the non-detection requires a stellar ionising radiation about four times higher than estimated. This is because, despite the fact that a stronger stellar high-energy emission ionises hydrogen more rapidly, it also increases the upper atmosphere heating and expansion, pushing the interaction region with the stellar wind farther away from the planet, where the planet atmospheric density that remains neutral becomes smaller and the production of energetic neutral atoms less efficient. Conclusions: Comparing the results of our grid of models with what is expected and estimated for the stellar wind and high-energy emission, respectively, we support the idea that the atmosphere of $π$ Men c is likely not hydrogen-dominated.

Conflicting values ; "official" and "counter" meta-narratives on human rights in Canadian foreign policy - the case of East Timor
Creators: name: Wolansky, Randall
Publisher: name: University of British Columbia
Year: 2009

description: Belief in human rights is a value central to the Canadian self-image. Canadians view the development of Canada's international peacekeeping role and overseas development assistance program in the post-1945 era as the foreign policy manifestation of this belief. It has led to the national myth of the country as a "Humanitarian Middle Power". Canada's response to Indonesia's oppressive occupation of East Timor (1975 - 1999) contradicted this national myth. The concept of meta-narrative, of political mythmaking, is used to examine the reasons why the Liberal and Progressive Conservative governments in Ottawa during this period perceived Canada's national interest in maintaining a strong economic relationship with Jakarta over the protection of human rights in East Timor. These "Official" meta-narratives were countered by Canadian human rights activists, such as the East Timor Alert Network, who stressed the primacy of human rights in foreign-policy decision-making. Ultimately, this debate represents a conflict of values in Canadian society. The "Official" meta-narrative has developed since World War II in active support of the capitalist world-system dominated by the United States, whereas the "Counter" meta-narrative challenges the morality of that system. The "Humanitarian Middle Power" myth, which is at the core of the Canadian identity vis-a-vis the international community, is not completely invalid, but it is greatly limited by the firm adherence of Canadian governments to the world economic structure.

The study was conducted on a sample of 20 runners in divided to an experimental and control group. The program was applied via suggested exercises in a hypoxic method on the experimental sample and leaving the control sample to be trained in the ordinary program. The researchers concluded that the use of suggested training program based on hypoxic training method has a positive effect on improving some functional variables, and it also affected a greater percentage than the ordinary program to improve results in the middle-distance running, specializing in 800 meters, so it is recommended to use the hypoxic training method to develop the physiological qualities of athletics.

description: A group of North Dakota lamb producers who are members of Valley Wool Growers Association identified several niche markets for high quality North Dakota lambs. The potential availability of a closed, but formerly federally inspected, livestock slaughter and meat processing facility in Steele County heightened their interest in determining the feasibility of a cooperatively owned lamb slaughter and processing facility. The cooperative would be patterned after existing and proposed slaughter cooperatives, whereby cooperative members would own shares to supply lambs to the plant on a year-round basis. The analysis was conducted in several sections corresponding to critical factors which affect feasibility of the plant. The critical factors analyzed included federal inspection requirements, the potential of an adequate supply of lambs, the potential for a viable niche market, plant investment and operating costs, expected return, alternative lamb purchase prices, alternative lamb carcass sales prices, and several investment and expense scenarios. The building and equipment investment was projected to be $1,468,000, which was higher than originally expected due to the extensive refurbishing necessary to meet federal inspection and increased capacity requirements. Plant operating expenses at full capacity were projected to be $3,013,877 per year which included $673,877 in operating expenses and $2,340,000 for lamb purchase. Income from lamb meat sales and pelts was estimated at $2,800,000 per year. The assumptions of purchasing 20,000 lambs per year for $0.90 per pound and selling for $2 per carcass pound resulted in an annual negative margin of $213,877 at full capacity. Therefore, other scenarios were investigated which would enable the plant to operate profitably. The maximum price that could be paid for lambs to pay all investment and operating costs, including a 7.5 percent return to member equity, was $0.8004 per pound. A 25 percent increase in projected costs would reduce the purchase price to $0.7358, or a reduction in the lamb carcass sales price to $1.80 per pound would reduce the lamb purchase price to $0.7004. The range in probable prices that could be paid for lambs is $0.70 to $0.80 per pound with a likely price of $0.75. The proposers of the cooperative will need to decide if prices in this range would be sufficient to lure enough member investors to provide the 20,000 lambs necessary to operate the plant.

description: The ultraviolet asymptotic behavior of the gluon propagator is evaluated in the maximal Abelian gauge in the SU(2) gauge theory on the basis of the renormalization-group improved perturbation theory at the one-loop level. Square-root singularities obtained in the Euclidean domain are attributed to artifacts of the one-loop approximation in the maximal Abelian gauge and the standard normalization condition for the propagator used in our study. It is argued that this gauge is essentially nonperturbative.

description: Synchronization instability of grid-tied converters during grid faults is a serious concern. For phase-locked loop (PLL) synchronized converters, synchronization stability during grid faults requires that PLL can resynchronize with the power grid. It is of great significance for meeting grid code specifications such as reactive current support. However, the synchronization in the context of high-impedance weak grid is not always readily achieved. On one hand, the terminal voltage of converters is changeable due to being susceptible to the output current. One the other hand, there is interaction between multiple converters interconnected to the grid. Therefore, loss of synchronism (LOS) of converters during grid faults likely occurs. Previous research has investigated the LOS issue of single-converter infinite-bus (SCIB) system, but mostly overlooked the interaction between multiple converters. Previous efforts to address the issue of LOS are also in doubt for multi-converter systems. This paper develops a multi-converter infinite-bus (MCIB) system model and analyzes the root cause of LOS with considering multi-converter interaction during grid faults. Moreover, a feedforward compensated PLL (FFC-PLL) method applicable for multi-converter systems is developed to address the LOS issue. Simulations results verify the effectiveness of the method.

description: The surface magnetic field configuration of the Ap star HD 118022 (78 Vir) has been reconstructed in the framework of the magnetic charge distribution (MCD) method from the analysis of Stokes $IQUV$ spectra obtained using the MuSiCoS spectropolarimeter at Pic du Midi Observatory. Magnetically-sensitive Fe~{\sc ii} lines were primarily employed in the analysis, supposing that iron is evenly distributed over the stellar surface. We show that the Stokes $IQUV$ profile shapes and variations of 78 Vir can be approximately fit assuming a global magnetic field configuration described by a slightly decentered, inclined magnetic dipole of polar surface intensity approximately 3.3~kG. The derived inclinations of the stellar rotational axis to the line of sight $i=24\pm 5\degr$ as well as to the magnetic dipole axis $β=124\pm5\degr$ are in good agreement with previous estimations by other authors, whereas the sky-projected position angle\thanks{$Ω$ increases clockwise from the axis to the North Celestial Pole and relates to the azimuth angle $Θ$ specified by Landolfi at al.~(\cite{Landolfi+93}) as $Ω=360\degr-Θ$.} of the stellar rotation axis $Ω\sim110\degr$ is reported here for the first time. In addition, several lines of Cr~{\sc ii} and Ti~{\sc ii} were studied, yielding evidence for non-uniform surface distributions of these elements, and magnetic field results similar to those derived from Fe.

description: We present a novel parallelisation scheme that simplifies the adaptation of learning algorithms to growing amounts of data as well as growing needs for accurate and confident predictions in critical applications. In contrast to other parallelisation techniques, it can be applied to a broad class of learning algorithms without further mathematical derivations and without writing dedicated code, while at the same time maintaining theoretical performance guarantees. Moreover, our parallelisation scheme is able to reduce the runtime of many learning algorithms to polylogarithmic time on quasi-polynomially many processing units. This is a significant step towards a general answer to an open question on efficient parallelisation of machine learning algorithms in the sense of Nick's Class (NC). The cost of this parallelisation is in the form of a larger sample complexity. Our empirical study confirms the potential of our parallelisation scheme with fixed numbers of processors and instances in realistic application scenarios.

description: Agricultural industries in small geographical areas with limited acreage tend to be overlooked by those not associated with the growing region or industry. Sugarbeets continue to be produced in a relatively small geographic area and with relatively limited acreage in North Dakota and Minnesota. These factors, along with continued debate over policies affecting domestic sugar industries and recent industry expansions, help justify a continued assessment of the economic importance of the sugarbeet industry to the regional economy. Revenues from sugarbeet production and expenditures by processors to North Dakota and Minnesota entities in fiscal 1997 represented the direct economic impacts from the industry. Expenditure information was provided by sugarbeet processing and marketing cooperatives. Secondary economic impacts were estimated using input-output analysis. The sugarbeet industry planted 654,400 acres and harvested 11.9 million tons in 1996. Production and processing activities generated $831.1 million in direct economic impacts. Total (direct and secondary) annual economic impacts from the sugarbeet industry were estimated at $2.3 billion. Direct and secondary employment in the industry was 2,486 and 30,436 full-time equivalent jobs, respectively. Tax revenues generated by the industry in North Dakota and Minnesota were $51 million. In real terms, gross business volume of the sugarbeet industry in the two states has increased 74 percent since 1987. Increases in business activity from the industry have resulted from expanded acreage and increased processing activities. The sugarbeet industry remains an important agricultural industry in North Dakota and Minnesota.

description: The landscape of machine learning applications is changing rapidly: large centralized datasets are replaced by high volume, high velocity data streams generated by a vast number of geographically distributed, loosely connected devices, such as mobile phones, smart sensors, autonomous vehicles or industrial machines. Current learning approaches centralize the data and process it in parallel in a cluster or computing center. This has three major disadvantages:(i) it does not scale well with the number of data-generating devices since their growth exceeds that of computing centers,(ii) the communication costs for centralizing the data are prohibitive in many applications, and (iii) it requires sharing potentially privacy-sensitive data. Pushing computation towards the data-generating devices alleviates these problems and allows to employ their otherwise unused computing power. However, current parallel learning approaches are designed for tightly integrated systems with low latency and high bandwidth, not for loosely connected distributed devices. Therefore, I propose a new paradigm for parallelization that treats the learning algorithm as a black box, training local models on distributed devices and aggregating them into a single strong one. Since this requires only exchanging models instead of actual data, the approach is highly scalable, communication-efficient, and privacy-preserving.Following this paradigm, this thesis develops black-box parallelizations for two broad classes of learning algorithms. One approach can be applied to incremental learning algorithms, ie, those that improve a model in iterations. Based on the utility of …

description: We consider the Dirichlet problem for a class of quasilinear elliptic systems in domain with irregular boundary. The principal part satisfies componentwise coercivity condition and the nonlinear terms are Carathéodory maps having Morrey regularity in $x$ and verifying controlled growth conditions with respect to the other variables. We have obtained boundedness of the weak solution to the problem that permits to apply an iteration procedure in order to find optimal Morrey regularity of its gradient.

Dall’s sheep (Ovis dalli dalli Nelson, 1884) sexual segregation : interactions between two hypotheses
Creators: name: Corti, Paulo

description: Four hypotheses have been proposed to explain sexual segregation in sexually dimorphic ungulates. I tested two of these on a Dall's sheep (CV/'s dalli dalli) population in Kluane National Park in Yukon, Canada. In the first, the reproductive-strategy hypothesis, males are predicted to feed in the best foraging areas to enhance their condition for intrasexual competition. Females are predicted to use areas with lower predation risk to raise offspring. In the second, the sexual dimorphism-body size hypothesis, females should use the best forage areas to satisfy the nutritional demands of gestation and lactation, and males due to their greater absolute metabolic requirements and larger body size have to forage on more available forages, but lower quality. I found Dall's sheep had a high social segregation but limited habitat segregation between males and females. Males were further from security cover in more gentle terrain than were maternal groups that used cliff or talus slopes. Maternal groups were located at higher altitudes than were males because most security cover was close to mountain peaks. Lamb presence was a factor increasing predation risk and affecting maternal groups' behaviour and distribution towards security cover. Group distance from security cover was negatively correlated with the proportion of individuals lying down for maternal groups without lambs. When this group type left security cover they were constantly active, either feeding or moving. The forage density index (FDI) values varied significantly, with the areas used by males having higher FDIs than areas used by maternal groups. Nutritional components were similar, but fibre content was significantly higher in areas used by males. Signs of wolves (Canis lupus) and predation events on Dall's sheep were recorded only at male sites. These data support the idea that male areas have a greater risk of predation. My results primarily support the reproductive-strategy hypotheses, indicating that predation plays a key role in the development of sexual segregation in Dall's sheep. However, I also found evidence to support one prediction of the sexual dimorphism-body size hypothesis, where males use areas higher in forage availability but lower in quality than female areas.

description: We surveyed agricultural loan officers and their supervisors in North Dakota to learn what factors influenced the decision to make loans to farmers investing in new agricultural cooperatives. We found that the Farm Credit Services and other large institutions made a disproportionately large share of the loans. Furthermore, institutions with minimal equity, but with low levels of non-current loans and a high return on equity, were more likely than others to make the loans. Experienced agricultural loan officers and those who attended a cooperative's information meeting or reviewed the business plan were more likely to make loans. Loan officers granted loans to applicants who met conservative lending criteria. The decision was not based on the loan officer's attitudes toward cooperatives. Attitudes of loan officers toward cooperatives were generally positive. Most negative attitudes were expressed about the price of the stock, and the delivery contracts required by the cooperatives. Finally, loan officers believed cooperative stock was a risky investment, inferior to stock and mutual funds as stand alone investments.
