Simsite.net - a web-based construction management game
Creators: name: Fan, Harry Hongqin
Publisher: name: University of British Columbia
Year: 2009

description: The construction industry is distinguished by low productivity, high uncertainties and risks, and a long learning curve for university graduates entering the industry. Past and current simulation research proves that construction simulation games are effective as management learning tools in training and education of entry-level to intermediate-level participants. SimSite.Net is a construction management simulation game built on the Microsoft .Net platform; it represents a substantial enhancement of a previously developed game called SimSite 1.0b. Implemented as an interactive web site, the game is designed to allow users to plan, schedule and monitor an online virtual project, gaining hands-on experience about the decision-making process of a constructed facility. The basic concept of a Physical Component Breakdown Structure (PCBS), a Work Breakdown Structure (WBS), technology and method selection, resource assignment, Critical Path Method (CPM) scheduling, and the uncertainties involved in construction are all represented in the system, and the relationships involved in time-cost trade-off and productivity influences are explored throughout the game. The web site is comprised of three parts. The first part contains project documents and a reference library that allow the users to browse through the drawings, specifications, and photos of the project, and watch video clips demonstrating typical construction activities. In the second part, the user breaks down the project into components based on structure and constructability, defines activities, selects work methods for a number of important activities, defines network logic, and generates a planning and scheduling report from the system. In the third part, the system generates monthly reports after incorporating perturbations from environmental and economical factors, and the user can adjust the resources and working time for the following month to bring the progress back onto schedule and costs under control. Delays in completion will subject the user to a liquidated damage charge on a daily basis. A project duration or cost exceeding the allowable limits will be deemed failure in the game play. The game is a typical three-tier web application with a project database hosted on SQL Server 2000 and a web application on a web server. A single-span railway bridge in Lions Bay, BC was selected for a case study. However, the game can be used for other projects by addition and modification of the project database.

description: This study employs correlation relationships to measure the strength of trade-offs between business and financial risks as a representative of the strategic capital adjustment process. Under different business risk measures based on varying lengths of historical farm income data, results suggest that farmers tend to adopt a myopic perspective when contemplating risk-balancing plans. Cross-sectional regression results for two-time period models covering the decade of the 1980s and 1990s yielded important implications. The liquidity-constrained environment of the 1980s emphasizes the combination of risk-balancing plans, specialization, and market revenue-enhancing strategies. In the 1990s, risk balancing becomes compatible with risk-reducing crop diversification and insurance protection plans.
title: Face Morphing and Morphing Attack Detection
Creators: name: Scherhag, Ulrich Johannes
Publisher: name: UNSPECIFIED
Year: 2021

description: In modern society, biometrics is gaining more and more importance, driven by the increase in recognition performance of the systems. In some areas, such as automatic border controls, there is no alternative to the application of biometric systems. Despite all the advantages of biometric systems, the vulnerability of these still poses a problem. Facial recognition systems for example offer various attack points, like faces printed on paper or silicone masks. Besides the long known and well researched presentation attacks there is also the danger of the so-called morphing attack. The research field of morphing attacks is quite young, which is why it has only been investigated to a limited extent so far. Publications proposing algorithms for the detection of morphing attacks often lack uniform databases and evaluation methods, which leads to a restricted comparability of the previously published work. Thus, the focus of this thesis is the comprehensive analysis of different features and classifiers in their suitability as algorithms for the detection of morphing attacks. In this context, evaluations are performed with uniform metrics on a realistic morphing database, allowing the simulation of various realistic scenarios. If only the suspected morph is available, a HOG feature extraction in combination with an SVM is able to detect morphs with a D-EER ranging from 13.25% to 24.05%. If a trusted live capture image is available in addition, for example from a border gate, the deep ArcFace features in combination with an SVM can detect morphs with a D-EER ranging from 2.71% to 7.17%.

description: Using 1971-2000 data, we examine the accuracy of corn and soybean production forecasts provided by the USDA and two private agencies. All agencies improved their forecasts as the harvest progressed, and forecast errors were highly correlated and unbiased. The relative forecast accuracy of the agencies varied by crop and month. For corn, USDA’s forecasts ranked as most accurate of the three agencies in all periods except for august during the recent period and improved most markedly as harvest progressed. For soybeans, forecast errors were very similar, with the private agencies ranking as most accurate for August and September and making largest relative improvements for August during the recent period. The USDA forecasts were dominant for October and November. Our findings identify several patterns of relative forecast accuracy that have implications for private and public decision makers.

description: This study determines the relative effects of price, cattle quality, and feeding performance factors on profit per head for fed cattle marketed via a grid structure. Two different data sets of cattle that were marketed in two different grid pricing systems are used in the analysis with comparisons of results made between grids. Grid base price and feeder cattle price are the most important determinants of profit over time in both grids. However, considering only nonprice variables, the cumulative quality of cattle in a pen is also an important profit determinant.

description: The proposed Free Trade Area of the Americas would join the world’s two largest processed orange producing regions: Brazil and the United States. Because the United States currently imposes a sizeable tariff on imported processed orange products, there is concern by U.S. orange growers over possible adverse effects resulting from tariff elimination. A model of the world processed orange market is developed as a spatial equilibrium model with implicit supply functions based on the dynamic behavior of orange production. The model is used to estimate the impact of U.S. tariff elimination on U.S. production, grower and processor prices, and imports. The results suggest a sizeable price impact on U.S. producers if the tariff is eliminated.

description: Since the farm financial crisis of the 1980s, Farm Credit System banks continue to merge and consolidate to enhance competitiveness. Two mixed-integer programming models of AgChoice Agricultural Credit Association (ACA), a recently merged ACA in Pennsylvania, were developed to determine the optimal number, location, and territory of branches. The approach suggests useful information can be determined regarding the reconfiguration process after bank mergers, especially given the fact that the current AgChoice ACA configuration is available for comparison purposes.

description: We report on a search for pair production of first-generation scalar leptoquarks (LQ) in ppbar collisions at sqrt(s)=1.96 TeV using an integrated luminosity of 252pb-1 collected at the Fermilab Tevatron collider by the D0 detector. We observe no evidence for LQ production in the topologies arising from LQLQbar->eqeq and LQLQbar->eqnuq, and derive 95% C.L. lower limits on the LQ mass as a function of beta, where beta is the branching fraction for LQ->eq. The limits are 241 and 218 GeV/c2 for beta=1 and 0.5, respectively. These results are combined with those obtained by D0 at sqrt(s)=1.8 TeV, which increases these LQ mass limits to 256 and 234 GeV/c2.

description: Lead iodide perovskites have attracted considerable interest in the upcoming photovoltaic technologies and optoelectronic devices. Therefore, an accurate theoretical description of the electronic and optical properties especially to understand the excitonic effects in this class of materials is of scientific and practical interest. However, despite several theoretical research endeavours in past, the most accurate analysis of the key electronic parameters for solar cell performance, such as optical properties, effective mass, exciton binding energy (E$_B$) and the radiative exciton lifetime are still largely unknown. Here, we employ state-of-the-art first-principles based methodologies viz. hybrid functional(HSE06) combined with spin-orbit coupling (SOC), many-body perturbation theory (GW, BSE), model-BSE (mBSE), Wannier-Mott (WM) and Density Functional Perturbation Theory (DFPT). By taking a prototypical model system viz. APbI$_3$ (A = Formamidinium (FA), methylammonium (MA), and Cs), an exhaustive analysis is presented on the theoretical understanding of the optical, electronic and excitonic properties. We show that tuning of exact exchange parameter ($α$) in HSE06 calculations incorporating SOC, followed by single shot GW, and BSE play a pivotal role in obtaining a reliable predictions for the experimental bandgap. We demonstrate that mBSE approach improves the feature of optical spectra w.r.t experiments. Furthermore, WM approach and ionic contribution to dielectric screening (below 16 meV) ameliorate the E$_B$. Our results reveal that the direct-indirect band gap transition (Rashba splitting) may be a factor responsible for the reduced charge carrier recombination rate in MAPbI$_3$ and FAPbI$_3$. The role of cation ''A'' for procuring the long-lived exciton lifetime is well understood. This proposed methodology allows to design new materials with tailored excitonic properties.

If a function $f\hbox{:} D_{n} \to \R^n$ satisfies the inequality $||< f(x), f(y) >| - |< x, y >|| \leq ϕ(x,y)$ for an appropriate control function $ϕ(x,y)$ and for all $x, y \in D_{n}$, then $f$ satisfies the generalized orthogonality equation for any $x, y \in D_{n}$.

description: Knowledge of parton distribution functions (PDFs) at large momentum fraction $ x $ is not only important to study the flavor and spin dynamics of quarks in the nucleon, but also to search for signals of new physics at collider experiments. It is well known now that the nonperturbative QCD effects generally play a more significant role at such kinematic regions. In this work, we present an open-source QCD analysis of PDFs considering target mass corrections (TMCs) and higher-twist (HT) effects which are necessary when the analysis includes also data points from deep inelastic scattering (DIS) with larger values of $ x $ and smaller values of photon virtuality $ Q^2 $. To this aim, we use the xFitter package, as a comprehensive and powerful tool for studying PDFs. We report and discuss our recent activities on the implementation of TMCs and HT effects in the xFitter framework in a user-friendly way, so that the user can switch on or off them, and also choose between different options. We check the validity of the modifications by performing sample analyses of PDFs considering TMCs and HT effects and using a wide range of DIS data.

The study analyses consumer interest towards nutritional label and claims, trying to identify the information consumers consider important during their purchasing decisions, and the main characteristics of consumers interested in nutritional claims and nutritional labels use. The survey was conducted in northern Italy and the sample consists of 1,025 consumers. We estimate one binary logit model to investigate the use of the nutritional label, and other seven ordinal regression models to analyze the consumer interest towards the nutritional claims. The results suggest consumers who use nutritional label are interested in nutritional attributes, food safety, and quality concerns, whereas consumers interested in nutritional claims show less interest in food safety and consider important factors such as price, brand and flavour.

description: Switchgrass, a warm-season perennial grass, native to the region, has received considerable interest for its potential role as a dedicated feedstock for cellulosic-based bio-fuels. This research examined the farm-gate price needed for switchgrass to provide per-acre net returns equal to those obtained from traditional crops in south central North Dakota. Future production costs for switchgrass and net returns from traditional crops were estimated for three soil productivity classes and also were developed to reflect the historical revenue and cost patterns associated with producers who are typically more or less profitable (i.e., average net return per acre) than regional averages. Prices were calculated using an annualized equivalent analysis of switchgrass production costs and net returns from traditional crops from 2008 through 2017. Switchgrass production costs ranged from just over $40 per ton on marginal soils to $34.80 per ton on highly productive soils. Breakeven switchgrass prices across the three soil productivity classes ranged from $47 per ton in the low productivity soils to $76 per ton in the most productive soils. Production costs for low-profit producers were estimated at $47 per ton, compared to the regional average of $37.50 per ton. Switchgrass production costs for the remaining profitability groups ranged from about $33.50 per ton to about $36.75 per ton. The breakeven farm-gate price for switchgrass ranged from $56 per ton for the two lowest profitability groups to over $94 per ton for the most profitable producers. A key economic criterion influencing the breakeven price for switchgrass will be the foregone net revenue from displaced traditional crops. On marginal soils, just under one-third of the breakeven price was derived from the level of foregone net returns from traditional crops; whereas, over 80 percent of the breakeven price was derived from the level of foregone net returns from traditional crops on the most productive soils. As net returns from traditional crops decreased, the more that breakeven switchgrass prices approached production costs for switchgrass. Under current conditions of high input costs, escalating transportation costs, and given the increases in net returns from traditional crops, switchgrass, as a feedstock to a cellulosic ethanol plant, will be more expensive than previously estimated.

description: The development of schemes for coherent nonlinear time-domain spectroscopy in the extreme-ultraviolet regime (XUV) has so far been impeded by experimental difficulties that arise at these short wavelengths. In this work we present a novel experimental approach, which facilitates the timing control and phase cycling of XUV pulse sequences produced by harmonic generation in rare gases. The method is demonstrated for the generation and high spectral resolution characterization of narrow-bandwidth harmonics ($\approx14\,$eV) in argon and krypton. Our technique simultaneously provides high phase stability and a pathway-selective detection scheme for nonlinear signals - both necessary prerequisites for all types of coherent nonlinear spectroscopy.

description: Tourism is increasingly seen as a potential lever towards high economic growth, measured both in terms of income and employment. In recent years, interest in tourism has spread rapidly throughout many small and medium European cities, which previously have not considered themselves as tourist destinations. This paper reviews and summarises the existing literature on the economic assessment of tourism with the objectives of, firstly, identifying the main categories of impacts and, secondly, constructing an inventory of methodologies available to assess them. We will progress step by step, starting from the most simplistic approaches and relaxing assumptions as we proceed. Firstly, we assume a static setting, with spare capacity. In such a setting (partial equilibrium), prices do not respond to demand shocks: only quantities (production, income and jobs) adjust. Secondly, we relax this assumption and assume that there is no spare capacity: prices respond to increasing demand (general equilibrium), leading to reallocation of resources across sectors. We then move from a static to a dynamic setting and survey those contributions that look at the relationship between tourism specialisation and long-run growth.

description: When do nonparametric Bayesian procedures ``overfit''? To shed light on this question, we consider a binary regression problem in detail and establish frequentist consistency for a certain class of Bayes procedures based on hierarchical priors, called uniform mixture priors. These are defined as follows: let $ν$ be any probability distribution on the nonnegative integers. To sample a function $f$ from the prior $π^ν$, first sample $m$ from $ν$ and then sample $f$ uniformly from the set of step functions from $[0,1]$ into $[0,1]$ that have exactly $m$ jumps (i.e., sample all $m$ jump locations and $m+1$ function values independently and uniformly). The main result states that if a data-stream is generated according to any fixed, measurable binary-regression function $f_0\not\equiv1/2$, then frequentist consistency obtains: that is, for any $ν$ with infinite support, the posterior of $π^ν$ concentrates on any $L^1$ neighborhood of $f_0$.

description: Die Modifizierung von Brennstoffzellenkatalysatoren mit hydrophoben Ionischen Flüssigkeiten nach dem "Solid Catalyst with Ionic Liquid Layer (SCILL)" Prinzip wurde bereits in verschiedenen Arbeiten auf Basis von Pt/C-Katalysatoren untersucht. Im Rahmen dieser Arbeit wurde das SCILL-Konzept auf bi- und trimetallische PtNi/C, PtNiCo/C und PtNiMo/C-Katalysatoren übertragen und zudem der Einfluss unterschiedlicher Kohlenstoffträger innerhalb eines SCILL-Systems untersucht. Neben unterschiedlichen Ionischen Flüssigkeiten wurde hierbei auch die Menge an Ionischer Flüssigkeit variiert. Weiterhin wurde das Degradationsverhalten der eingesetzten SCILL-Katalysatoren unter elektrochemischer Zyklisierung analysiert. Die Bestimmung von Aktivität und Stabilität erfolgte anhand von RDE-Experimenten. Die Ergebnisse zeigen, dass das SCILL Konzept erfolgreich auf bi- (PtNi/C) und trimetallische (PtNiCo/C und PtNiMo/C) Elektrokatalysatoren angewendet werden kann. Hierbei konnte in Abhängigkeit der Ionischen Flüssigkeit eine Erhöhung der ORR-Aktivität festgestellt werden. Die größte Aktivitätssteigerung konnte mit der Ionischen Flüssigkeit [MTBD][BETI] erzielt werden. Bei der Variation der Kohlenstoffträger zeigte sich, dass das SCILL Konzept auf alle getesteten Kohlenstoffträger (Ketjenblack, Vulcan, Nanotubes) angewendet werden konnte und hierbei vergleichbare Aktivitätstrends resultierten. Bei Stabilitätsuntersuchungen wurde festgestellt, dass Ionische Flüssigkeiten aufgrund eines hohen Metallauflösungsvermögens jedoch auch einen negativen Einfluss auf die Stabilität von trimetallischen Systemen haben können.

description: Recent PHOBOS measurements of the excitation function for the pseudo-rapidity dependence of elliptic flow in Au+Au collisions at RHIC, have posed a significant theoretical challenge. Here we show that these differential measurements, as well as the RHIC measurements on transverse momentum satisfy a universal scaling relation predicted by the Buda-Lund model, based on exact solutions of perfect fluid hydrodynamics. We also show that recently found transverse kinetic energy scaling of the elliptic flow is a special case of this universal scaling.

description: The Cassini and Juno probes have revealed large coherent cyclonic vortices in the polar regions of Saturn and Jupiter, a dramatic contrast from the east-west banded jet structure seen at lower latitudes. Debate has centered on whether the jets are shallow, or extend to greater depths in the planetary envelope. Recent experiments and observations have demonstrated the relevance of deep convection models to a successful explanation of jet structure and cyclonic coherent vortices away from the polar regions have been simulated recently including an additional stratified shallow layer. Here we present new convective models able to produce long-lived polar vortices. Using simulation parameters relevant for giant planet atmospheres we find flow regimes that are in agreement with geostrophic turbulence (GT) theory in rotating convection for the formation of large scale coherent structures via an upscale energy transfer fully three-dimensional. Our simulations generate polar characteristics qualitatively similar to those seen by Juno and Cassini: they match the structure of cyclonic vortices seen on Jupiter; or can account for the existence of a strong polar vortex extending downwards to lower latitudes with a marked spiral morphology and the hexagonal pattern seen on Saturn. Our findings indicate that these vortices can be generated deep in the planetary interior. A transition differentiating these two polar flows regimes is described, interpreted in terms of different force balances and compared with previous shallow atmospheric models which characterised polar vortex dynamics in giant planets. In addition, the heat transport properties are investigated confirming recent scaling laws obtained in the context of reduced models of GT.

description: In this paper we investigate the impacts of abolishing the Common Agricultural Policy (CAP) for the post-2013 European Union (EU) financial perspective and the impacts of re-investing the released funds on research and development (R&D). We apply a linked system of models to analyze the impacts for the EU member states. The linked system consists of five land-use sector models (agriculture, forestry, urban area, tourism and transport infrastructure), which are connected to a macro-econometric model. Additionally, a land cover model is used to disaggregate land use countries to a 1 km² grid. Three scenarios are analysed. In the “baseline” currently decided policies are assumed to be continued until 2025. In the “tax rebate” scenario agricultural support (first pillar) is removed, and the member states’ contributions to EU lowered. In the “R&D investments” scenario agricultural support is also removed, and the released funds are used to increase general R&D efforts in the EU. We find that in both liberalization scenarios, agricultural producer prices drop compared to the baseline. Agricultural production drops too, but less so in the “R&D investment” scenario due to productivity gains resulting from the increased R&D spending. In some countries, the productivity gains totally offset the negative impact of liberalisation on agricultural production. Smaller agricultural production implies less agricultural land use, and the more so in the “R&D Investment” scenario where productivity increases. The fall in agricultural production and prices negatively affects economic activity and households’ purchasing power, but the reduced direct taxation compensates this effect and results in a GDP gain of 0.53% and 0.8 million additional jobs. In “R&D investment” GDP gain reaches 2.57% and yields 2.95 million additional jobs in EU in 2025. The GDP, consumption and employment gains in the “R&D Investment” scenario widely exceed the losses in the agriculture sectors. The analysis indicates that if no external effects of agriculture are considered, then the CAP is an inefficient use of tax money, and that a considerable contribution to reaching the goals of the Lisbon agenda would be achieved if the same amount of money was instead invested in R&D.

description: Biological networks are characterized by their connectivity and topology but also by their ability to transport materials. In the case of random transportation, the efficacy is measured by the time it takes to travel between two nodes of the network. We study here the consequences of a unidirectional transport mechanism occurring in the endoplasmic reticulum (ER) network, a structure present in the cell cytoplasm. This unidirectional transport mechanism is an active-waiting transportation, where molecules have to wait a random time before being transported from one node to the next one. We develop here a general theory of transport in an active network and find an unusual network transportation, where molecules group together in redundant packets instead of being disperse. Finally, the mean time to travel between two nodes of the ER is of the order of 20 min, but is reduced to 30 s when we consider the fastest particles because it uses optimal paths. To conclude, the present theory shows that unidirectional transport is an efficient and robust mechanism for fast molecular redistribution inside the ER.

description: Legged robots need to make contact with irregular surfaces, when operating in unstructured natural terrains. Representing and perceiving these areas to reason about potential contact between a robot and its surrounding environment, is still largely an open problem. This paper introduces a new framework to model and map local rough terrain surfaces, for tasks such as bipedal robot foot placement. The system operates in real-time, on data from an RGB-D and an IMU sensor. We introduce a set of parametrized patch models and an algorithm to fit them in the environment. Potential contacts are identified as bounded curved patches of approximately the same size as the robot's foot sole. This includes sparse seed point sampling, point cloud neighborhood search, and patch fitting and validation. We also present a mapping and tracking system, where patches are maintained in a local spatial map around the robot as it moves. A bio-inspired sampling algorithm is introduced for finding salient contacts. We include a dense volumetric fusion layer for spatiotemporally tracking, using multiple depth data to reconstruct a local point cloud. We present experimental results on a mini-biped robot that performs foot placements on rocks, implementing a 3D foothold perception system, that uses the developed patch mapping and tracking framework.

description: This paper discusses the long run effect of changes in the age distribution of Spanish population on the unemployment rate, disaggregated by sex and age segments in the light of cointegration theory given the non stationarity of the series. Four main results are obtained. First, empirical analysis does not provide a clear scheme concerning the long run relationships between population variables and the specificunemployment rates for different groups. Second, as a first approximation one can detect the existence of, at least, one long run equilibrium relationship in all sex-age groups, except for the ones including the middle aged unemployed female workers and oldest unemployed female workers. Third, a more thorough analysis enables us to justify the existence of such long run relationships for the youngest male workers and middle aged male workers. One cannot argue, however, a joint evolution of population variables and the unemployment rates associated with female workers and to the oldest male workers. Fourth, the short run dynamics of unemployment rates for the youngest (male and female workers) and the middle age male workers is affected by the transitory deviations from these long run relationships. Hence, from an applied economics point of view, the result stresses the likely failure of employment policies which do not take into account the heterogeneous composition of unemployed workers. It stresses the need to design particular policies for specific groups of workers depending on their age and sex characteristics.

description: Different from the usual tetraquark assignment to charged $Z_c(3885)$ and $Z_c(4025)$ charmoniumlike structures, in this letter we propose a universal non-resonant explanation to decode these $Z_c$'s, which is based on a special dynamical behavior of $e^+e^-\to D^{(*)}\bar{D}^*π$. Our study shows that $Z_c(3885)$ and $Z_c(4025)$ are only the reflection from the $P$-wave charmed meson $D_1(2420)$ involved in $e^+e^-\to D^{(*)}\bar{D}^*π$. Obviously, the present work provides a unique perspective, which can be examined by future experiments like BESIII and BelleII.
