description: Electronic and optical products are vulnerable under mechanical shock environment. Designed products need to be validated by shock testing and/or numerical simulation, using representative acceleration-time history signals. However, specifications derived from measurements are normally given in terms of shock response spectrum (SRS) without a corresponding time history signal, and therefore, there is a need to synthesis acceleration-time histories from a given SRS specification. This paper proposed a net zero displacement filter and a realistic time history synthesis method. By scaling a relevant field measurement, acceleration-time histories can be synthesized, which can meet the net zero displacement constrain and a given SRS specification within $\pm$3 dB margin.

Balancing in-between : emerging concepts of Nikkei identity explored through Hapa young adults in multicultural Canada
Creators: name: Sekita, Misato
Publisher: name: University of British Columbia
Year: 2009

description: The establishment of Nikkei Place in 2000 was a turning point for the Vancouver Nikkei community. The term Nikkei, which is used throughout the world to designate those who are of Japanese descent and live outside of Japan, has been recaptured and redefined at a local level. This allows not only Japanese Canadians but also Ijusha (those born in Japan who are more recent immigrants), and Hapa (those born from a union of Japanese Canadian and non-Nikkei parents) to be embraced by and to rejuvenate the community. This research discusses the struggle and achievement of the Nikkei community in Vancouver, Canada that strives to remain as a community. I argue that Nikkei in Vancouver comprise a synthesis of ethnic community and cultural community that requires constant redefining of membership and expansion of boundaries. As a method of my research, I conducted participant observation field work along with ten semi-structured interviews, eight of them with Hapa. Since many of the studies on the history of Japanese Canadians are narrative, an historical review provided not only background information but also served as a part of my method. The history of the Japanese Canadian community and its relation to multiculturalism in Canada explains the current nature of the Nikkei community in Vancouver. The results of this research suggest people hope to sustain a community by way of redefining the external boundary in relationship to multicultural Canada and the internal boundaries within the heterogeneous Nikkei community. Through interviews with Hapa young adults of Nikkei in Vancouver, much diversity was found among them which reaffirmed the diverse nature of the Nikkei community.

description: Amorphous silicon contains tunneling two-level systems, which are the dominant energy loss mechanisms for amorphous solids at low temperatures. These two-level systems affect both mechanical and electromagnetic oscillators and are believed to produce thermal and electromagnetic noise and energy loss. However, it is unclear whether the two-level systems that dominate mechanical and dielectric losses are the same; the former relies on phonon-TLS coupling, with an elastic field coupling constant, $γ$, while the latter depends on a TLS dipole moment, $p_0$, which couples to the electromagnetic field. Mechanical and dielectric loss measurements as well as structural characterization were performed on amorphous silicon thin films grown by electron beam deposition with a range of growth parameters. Samples grown at 425 $^{\circ}$C show a large reduction of mechanical loss (34 times) and a far smaller reduction of dielectric loss (2.3 times) compared to those grown at room temperature. Additionally, mechanical loss shows lower loss per unit volume for thicker films, while dielectric loss shows lower loss per unit volume for thinner films. Analysis of these results indicate that mechanical loss correlates with atomic density, while dielectric loss correlates with dangling bond density, suggesting a different origin for these two energy dissipation processes in amorphous silicon.

description: Roccia San Sebastiano is a tectonic-karstic cave located at the foot of the southern slope of Mt. Massico, in the territory of Mondragone (Caserta) in Campania (southern Italy). Systematic excavation has been carried out since 2001, leading to the partial exploration of an important Pleistocene deposit, extraordinarily rich in lithic and faunal remains. The aim of this paper is to (1) present the stratigraphic sequence of Roccia San Sebastiano, and (2) technologically describe the lithic materials of squares F14 t18, t19, t20; E16 t16, t17, t18 recently recognised as Uluzzian. The stratigraphic sequence is more than 3 metres thick and dates from the Middle to the Upper Palaeolithic. It contains different techno-complexes: Gravettian, Aurignacian, Uluzzian and Mousterian. In the Uluzzian lithic assemblage mostly local pebbles of chert were used in order to produce small-sized objects. The concept of debitage mainly deals with unidirectional debitage with absent or fairly accurate management of the convexities and angles; the striking platforms are usually natural or made by one stroke. It is attested the use of both direct freehand percussion and bipolar technique on anvil in the same reduction sequence. Amongst the retouched tools the presence of two lunates is of note. This study of the Roccia San Sebastiano Uluzzian lithic complexes is significant for understanding the dynamics of the transition from Middle to Upper Palaeolithic in the Tyrrhenian margin of southern Italy.

description: This study examines the financial performance and stress experienced by beginning and retired farms in the U.S. Using USDA’s ARMS data, probit models are estimated to study the personal and farm characteristics that affect whether or not the financial ratios fall into critical zones. The results show that older farmers and larger farms are less likely to experience financial stress while hobby farms and livestock farms are more likely to experience financial stress. The results for beginning and retired farmers indicate fewer significant effects.

description: In experimental studies, children exposed to television food ads chose less healthy snacks and consumed more food overall, as compared with children exposed only to ads for toys. These findings, however, do not indicate that TV viewing causes a decrease in diet quality or an increase in weight. Other factors correlated with TV watching, such as neighborhood and parent and child characteristics, may be more to blame. We estimate the effect of an additional hour of television on total calories and the quality of food consumed during a day for children 6 to 18 years old. This research is the first to use a first difference (fixed effects) estimation strategy to investigate the impact of television on daily food consumption among children in the United States.

description: We review the mechanisms of supersymmetry breaking mediation that occur in sequestered models, where the visible and the hidden sectors are separated by an extra dimension and communicate only via gravitational interactions. By locality, soft breaking terms are forbidden at the classical level and reliably computable within an effective field theory approach at the quantum level. We present a self-contained discussion of these radiative gravitational effects and the resulting pattern of soft masses, and give an overview of realistic model building based on this set-up. We consider both flat and warped extra dimensions, as well as the possibility that there be localized kinetic terms for the gravitational fields.

description: This dissolution of the Soviet Union served the state-directed linkages between state-owned farms and agribusiness enterprises ordered by the command economic system. Likewise, the dissolution disrupted marketing channels connecting the agricultural sector to a market economy those of other former republics. The transition to a market economy requires a transformation in the political and economic structures of state-owned farms and state-owned agribusiness enterprises. Directors of state-owned farms in Kazakhstan face major challenges. The primary consideration is how the farm should be organized after privatization, that is, whether the farm should be transformed into a cooperative, a joint stockholding company, or divided into several private, individual farm operations or partnerships.

description: A critical aspect of crowds' evacuation processes is the dynamism of individual decision making. Here, we investigate how to favor a coordinated group dynamic through optimal exit-choice instructions using behavioral strategy optimization. We propose and evaluate an adaptive guidance system (Cell-based Crowd Evacuation, CellEVAC) that dynamically allocates colors to cells in a cell-based pedestrian positioning infrastructure, to provide efficient exit-choice indications. The operational module of CellEVAC implements an optimized discrete-choice model that integrates the influential factors that would make evacuees adapt their exit choice. To optimize the model, we used a simulation-optimization modeling framework that integrates microscopic pedestrian simulation based on the classical Social Force Model. We paid particular attention to safety by using Pedestrian Fundamental Diagrams that model the dynamics of the exit gates. CellEVAC has been tested in a simulated real scenario (Madrid Arena) under different external pedestrian flow patterns that simulate complex pedestrian interactions. Results showed that CellEVAC outperforms evacuation processes in which the system is not used, with an exponential improvement as interactions become complex. We compared our system with an existing approach based on Cartesian Genetic Programming. Our system exhibited a better overall performance in terms of safety, evacuation time, and the number of revisions of exit-choice decisions. Further analyses also revealed that Cartesian Genetic Programming generates less natural pedestrian reactions and movements than CellEVAC. The fact that the decision logic module is built upon a behavioral model seems to favor a more natural and effective response. We also found that our proposal has a positive influence on evacuations even for a low compliance rate (40%).

A market framework was employed to derive the short-run welfare impacts to consumers and producers (users and non-users) of the removal of pesticides currently registered for use on sorghum. It was projected that the loss of atrazine, the most widely used pesticide in sorghum production, would have the largest overall impact, with an estimated total welfare loss between $58 and $65 million.

Risk factor analysis, continuous monitoring and root cause analysis for Teekay Shipping
Creators: name: Chen, Shengyuan
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is based on an industry project with Teekay Shipping Co ., which is an international transportation service provider for oil companies, refiners and traders. Teekay is interested in knowing which factors contribute most to its operating incidents and accidents. Based on available data, namely vessel name, team, type, hull, and age, as well as incident and accident records, we quantified in this thesis the effects of these factors on the incident and accident frequency. The thesis presented the technical details of the Poisson regression analysis, which we used for quantifying the risk factors. Teekay is also interested in having a consistent method to present Teekay's overall risk picture, and to indicate best investment areas for its risk reducing purpose. Teekay has already implemented an Online Root Cause Analyses (ORCA) system, which collects the direct cause and root cause soon after an incident happens. We reviewed the ORCA system and made suggestions about certain parts of the system which were subsequently revised. Furthermore, we designed a bubble chart tool to present the overall risk faced by Teekay. The bubble chart tool has the capacity to indicate best investment areas clearly, and it is consistent over time, thereby enabling Teekay to evaluate easily the risk mitigation effect of its earlier investment in risk management. Finally, we designed a continuous monitoring tool, which allows Teekay managers to interactively explore the relationships among near misses, incidents and accidents, and to compare event frequencies of various vessel groups, such as vessel team, age, type and hull structure. The powerful continuous monitoring tool provides Teekay managers a full- range view of the risks the company faces. The design and the sample usage of this continuous monitoring tool are discussed in this thesis.

description: An all-fibre source of amplitude squeezed solitons utilizing the self-phase modulation in an asymmetric Sagnac interferometer is experimentally demonstrated. The asymmetry of the interferometer is passively controlled by an integrated fibre coupler, allowing for the optimisation of the noise reduction. We have carefully studied the dependence of the amplitude noise on the asymmetry and the power launched into the Sagnac interferometer. Qualitatively, we find good agreement between the experimental results, a semi-classical theory and earlier numerical calculations [Schmitt etl.al., PRL Vol. 81, p.2446, (1998)]. The stability and flexibility of this all-fibre source makes it particularly well suited to applications in quantum information science.

description: A foundational result in the theory of quantum computation known as the "principle of safe storage" shows that it is always possible to take a quantum circuit and produce an equivalent circuit that makes all measurements at the end of the computation. While this procedure is time efficient, meaning that it does not introduce a large overhead in the number of gates, it uses extra ancillary qubits and so is not generally space efficient. It is quite natural to ask whether it is possible to defer measurements to the end of a quantum computation without increasing the number of ancillary qubits. We give an affirmative answer to this question by exhibiting a procedure to eliminate all intermediate measurements that is simultaneously space-efficient and time-efficient. A key component of our approach, which may be of independent interest, involves showing that the well-conditioned versions of many standard linear-algebraic problems may be solved by a quantum computer in less space than seems possible by a classical computer.

description: Wide Area Cyber-Physical Systems (WA-CPSs) are a class of control systems that integrate low-powered sensors, heterogeneous actuators and computer controllers into large infrastructure that span multi-kilometre distances. Current wireless communication technologies are incapable of meeting the communication requirements of range and bounded delays needed for the control of WA-CPSs. To solve this problem, we use a Control-Communication Co-design approach for WA-CPSs, that we refer to as the $C^3$ approach, to design a novel Low-Power Wide Area (LPWA) MAC protocol called \textit{Ctrl-MAC} and its associated event-triggered controller that can guarantee the closed-loop stability of a WA-CPS. This is the first paper to show that LPWA wireless communication technologies can support the control of WA-CPSs. LPWA technologies are designed to support one-way communication for monitoring and are not appropriate for control. We present this work using an example of a water distribution network application which we evaluate both through a co-simulator (modelling both physical and cyber subsystems) and testbed deployments. Our evaluation demonstrates full control stability, with up to $50$\% better packet delivery ratios and $80$\% less average end-to-end delays when compared to a state of the art LPWA technology. We also evaluate our scheme against an idealised, wired, centralised, control architecture and show that the controller maintains stability and the overshoots remain within bounds.

description: This study examines the factors that influence the adoption intensity of a soil conservation technology in a developing country. Factors that influence adoption intensity may not be the same as those that influence the incidence of adoption. In this study, adoption intensity is defined as the percentage of total upland acreage planted with Sloping Agricultural Land Technology by farmers in the Philippines. Because of the dependent variable’s truncated nature, a Tobit model is used in the analysis. Economic theory and previous research provide the basis for the soil conservation decision variables included in the study. Results suggest that age of the head of household, tenure status, availability of family labor, and government programs have significant influence on adoption intensity. Contrary to expectations, income and education of farmers do not have significant impacts on adoption intensity. These results are discussed in term of their implications for conservation programs in developing countries.

description: We have performed a dielectric investigation of the ionic charge transport and the relaxation dynamics in plastic-crystalline 1-cyano-adamantane (CNA) and in two mixtures of CNA with the related plastic crystals adamantane or 2-adamantanon. Ionic charge carriers were provided by adding 1% of Li salt. The molecules of these compounds have nearly globular shape and, thus, the so-called revolving-door mechanism assumed to promote ionic charge transport via molecular reorientations in other PC electrolytes, should not be active here. Indeed, a comparison of the dc resistivity and the reorientational alpha-relaxation times in the investigated PCs, reveals complete decoupling of both dynamics. Similar to other PCs, we find a significant mixing-induced enhancement of the ionic conductivity. Finally, these solid-state electrolytes reveal a second relaxation process, slower than the alpha-relaxation, which is related to ionic hopping. Due to the mentioned decoupling, it can be unequivocally detected and is not superimposed by the reorientational contributions as found for most other ionic conductors.

Significant reduction of compensative Mn interstitials by varying the growth sequence of the structures followed by low temperature annealing led to high TC up to 250 K. The heterostructure with high TC exhibited peculiar anomalous Hall effect behavior, whose sign depends on temperature.

description: We analyse the 4-dimensional effective supergravity theories obtained from the Scherk--Schwarz reduction of M-theory on twisted 7-tori in the presence of 4-form fluxes. We implement the appropriate orbifold projection that preserves a G2-structure on the internal 7-manifold and truncates the effective field theory to an N=1, D=4 supergravity. We provide a detailed account of the effective supergravity with explicit expressions for the Kaehler potential and the superpotential in terms of the fluxes and of the geometrical data of the internal manifold. Subsequently, we explore the landscape of vacua of M-theory compactifications on twisted tori, where we emphasize the role of geometric fluxes and discuss the validity of the bottom-up approach. Finally, by reducing along isometries of the internal 7-manifold, we obtain superpotentials for the corresponding type IIA backgrounds.

description: Excessive government losses and pressure from end users of peanuts have increased the likelihood of a peanut support price and quota reduction in the 1995 farm bill. This study analyzes the economic impacts of reducing the national quota support price on North Carolina farm income and rural communities. Effects of policies that reduce quota support price for Virginia-type peanuts from $675 per ton to levels of $600 and $500 per ton are estimated. Reductions in the quota support price have significant impacts on quota owners and peanut producing regions. A 10 percent reduction in quota and a $500 support price would result in a $43 million income reduction to North Carolina.

description: Using an isospin- and momentum-dependent transport model we study the emission of free nucleons and the nuclear radial flow in central heavy-ion collisions induced by high energy radioactive beams. The midrapidity neutron/proton ratio and its transverse momentum dependence are found very sensitive to the high density behavior of nuclear symmetry energy. The nuclear radial flow, however, depends only weakly on the symmetry energy.

description: Let $f:\mathbb{R} \to \mathbb{R}$ be a stationary centered Gaussian process. For any $R>0$, let $ν_R$ denote the counting measure of $\{x \in \mathbb{R} \mid f(Rx)=0\}$. In this paper, we study the large $R$ asymptotic distribution of $ν_R$. Under suitable assumptions on the regularity of $f$ and the decay of its correlation function at infinity, we derive the asymptotics as $R \to +\infty$ of the central moments of the linear statistics of $ν_R$. In particular, we derive an asymptotics of order $R^\frac{p}{2}$ for the $p$-th central moment of the number of zeros of $f$ in $[0,R]$. As an application, we derive a functional Law of Large Numbers and a functional Central Limit Theorem for the random measures~$ν_R$. More precisely, after a proper rescaling, $ν_R$ converges almost surely towards the Lebesgue measure in weak-$*$ sense. Moreover, the fluctuation of $ν_R$ around its mean converges in distribution towards the standard Gaussian White Noise. The proof of our moments estimates relies on a careful study of the $k$-point function of the zero point process of~$f$, for any $k \geq 2$. Our analysis yields two results of independent interest. First, we derive an equivalent of this $k$-point function near any point of the large diagonal in~$\mathbb{R}^k$, thus quantifying the short-range repulsion between zeros of $f$. Second, we prove a clustering property which quantifies the long-range decorrelation between zeros of $f$.

description: Individuals exposed to odors from livestock facilities do not report annoyance uniformly. The reaction to a detectable odor depends on perceptions of the odor and its source which are mediated by odor attributes and personal factors. Correlations among these factors were tested in a rural context using date from a pilot study of seventeen households neighboring two swine operations in Michigan. Annoyance was measured as the impact of the neighboring facility on enjoyment of property. Characterization of odor as a problem was positively correlated with offensiveness, frequency and duration of exposure. Annoyance was negatively correlated with term of residence, current employment on a farm, and acquaintance with the facility owner. Annoyance was positively correlated with suburban characterization of the residence, unacceptability of the facility’s appearance and perception of odor as a problem. Strategies to minimize exposure augmented by increasing familiarity with the operation and owner can reduce annoyance.

Atmospheric Refraction Path Integrals in Ground-Based Interferometry
Creators: name: Mathar, Richard J.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The basic effect of the earth's atmospheric refraction on telescope operation is the reduction of the true zenith angle to the apparent zenith angle, associated with prismatic aberrations due to the dispersion in air. If one attempts coherent superposition of star images in ground-based interferometry, one is in addition interested in the optical path length associated with the refracted rays. In a model of a flat earth, the optical path difference between these is not concerned as the translational symmetry of the setup means no net effect remains. Here, I evaluate these interferometric integrals in the more realistic arrangement of two telescopes located on the surface of a common earth sphere and point to a star through an atmosphere which also possesses spherical symmetry. Some focus is put on working out series expansions in terms of the small ratio of the baseline over the earth radius, which allows to bypass some numerics which otherwise is challenged by strong cancellation effects in building the optical path difference.

description:

Le strategie cognitive adoperate nello studio e gli orientamenti motivazionali rivestono una funzione strategica nella promozione di un apprendimento di successo, ponendosi come specifici obiettivi di interventi di orientamento realizzati nel corso degli studi universitari per prevenire il rischio di drop-out. Questo lavoro illustra i risultati di uno studio trasversale che si è posto l’obiettivo di valutare l’influenza delle strategie cognitive, della motivazione verso lo studio, dell’autoefficacia percepita e dell’integrazione nel contesto accademico sull’intenzione di drop-out. I dati sono stati ottenuti attraverso un questionario online proposto a un campione di 461 studenti universitari, a cui sono stati sottoposti strumenti standardizzati finalizzati alla raccolta di informazioni sulle strategie cognitive adoperate nello studio, sulla motivazione accademica e sull’intenzione di abbandonare gli studi. I risultati hanno confermato le associazioni tra strategie di autoregolazione, orientamenti motivazionali, intenzione di abbandono degli studi e successo accademico, incoraggiando il ricorso a uno strumento come l’orientamento per promuovere nel soggetto una riflessione critica sulle proprie competenze, strategie di studio e orientamenti motivazionali.

description: University faculty have numerous responsibilities, but development of our own and our students’ human capital is our primary job. To effectively develop human capital of others requires investing heavily in our own capital. This includes being actively involved in discovering knowledge. In addition, as agricultural economists, our clientele demand relevant research output which requires regularly informing them about our research. Conducting research, publishing and communicating findings to interested parties better equips us to provide a quality teaching program. This article presents an accumulation of evidence supporting this view and provides insights about how these activities might be integrated.

description: Criteria for admission to graduate programs are used by departments and graduate schools to identify characteristics assumed to be associated with “success”. They allow for more uniformity in student ability and preparation so graduate education is more efficient. This study analyzes the relationship between selected student characteristics and experience and two proxies for “success”—graduate GPA and the probability of completing an Agricultural Economics graduate program. Data are from past students in the Department of Agricultural Economics at Texas Tech University. Statistical differences among the means of student characteristics were evaluated, a regression model was estimated to predict graduate GPA, and a logistical regression was estimated to examine the probability of not completing a graduate program. Results show some difference in characteristics between those who complete and do not complete. Graduate GPA is significantly related to citizenship, degree program, quantitative GRE score, and previous program GPA. However, only above-average prior GPA and existence of financial assistance are significantly related to the probability of nor completing a graduate program.

description: This paper examines strategies for integrating decision cases in the design of college courses. The benefits of decision cases are acknowledged but teaching strategies that rely solely on decision cases are challenged. A lack of real-world experience and knowledge among students can limit the effectiveness of teaching exclusively with decision cases in undergraduate or graduate classes. In such classes, decision cases need not be the sole teaching approach. Cases are much more often combined with lectures, problem sets and other teaching techniques. Suggested guidelines for incorporating cases into the design of courses are based on five critical topics: 1) course educational objectives, 2) the sequencing of case and other course material, 3) necessary facilities, timing and support 4) the number and mix of cases desirable in a course, and 5) evaluation of students.
