description: We show that loitering at high redshifts ($z \gsim 6$) can easily arise in braneworld models of dark energy which, in addition to being spatially flat, also accelerate at late times. Loitering is characterized by the fact that the Hubble parameter dips in value over a narrow redshift range which we shall refer to as the `loitering epoch'. During loitering, density perturbations are expected to grow rapidly. In addition, since the expansion of the universe slows down, its age near loitering dramatically increases. An early epoch of loitering is expected to boost the formation of high redshift gravitationally bound systems such as $10^9 M_\odot$ black holes at $z \sim 6$ and lower-mass black holes and/or Population III stars at $z > 10$, whose existence could be problematic within the LCDM scenario. Loitering models also help to reduce the redshift of reionization from its currently (high) value of $z_{\rm reion} \simeq 17$ in LCDM cosmology, thus alleviating a significant source of tension between observations of the high-redshift universe and theoretical model building. Currently a loitering universe accelerates with an effective equation of state $w < -1$ thus mimicking phantom dark energy. Unlike phantom, however, the late-time expansion of the universe in our model is singularity free, and a universe that loitered in the past will approach a LCDM model asymptotically in the distant future.
description: Latex, 20 pages, 4 figures. Important new results include an appendix and the observation that the redshift of reionization in loitering cosmology can be significantly lower than z = 17 inferred for LCDM from WMAP data.

description: The secondary modulation with the NeumannHoffman code increases the possibility of bit sign transition. Unlike other GNSS signals, there is no pilot component for synchronization in BeiDou B1/B3 signals, which increases the complexity in acquisition. A previous study has shown that the delay and multiplication (DAM) method is able to eliminate the bit sign transition problem, but it only applies to pretty strong signals. In this paper, a DAM-based BeiDou signal acquisition approach, called variable length data accumulation (VLDA), is proposed to acquire weak satellite signals. Firstly, the performance of DAM method versus the different delays is analyzed. The DAM operation not only eliminates bit sign transition, but it also increases noise power. Secondly, long-term signal is periodically accumulated to improve signal intensity in order to acquire weak signals. While considering the Doppler frequency shift of ranging codes, the signal length must be compensated before accumulating long-term signal. Finally, the fast-Fourier-transform based parallel code phase algorithm are used for acquisition. The simulation results indicate that the proposed VLDA method has better acquisition sensitivity than traditional non-coherent integration method under the same calculation amount. The VLDA method only requires approximately 27.5% of calculations to achieve the same acquisition sensitivity (35 dBHz). What is more, the actual experimental results verify the feasibility of the VLDA method. It can be concluded that the proposed approach is an effective and feasible method for solving the bit sign transition problem.

description: We assess the suitability of a recent high-resolution central scheme developed by Kurganov & Tadmor (2000) for the solution of the relativistic hydrodynamics equations. The novelty of this approach relies on the absence of Riemann solvers in the solution procedure. The computations we present are performed in one and two spatial dimensions in Minkowski spacetime. Standard numerical experiments such as shock tubes and the relativistic flat-faced step test are performed. As an astrophysical application the article includes two-dimensional simulations of the propagation of relativistic jets using both Cartesian and cylindrical coordinates. The simulations reported clearly show the capabilities of the numerical scheme to yield satisfactory results, with an accuracy comparable to that obtained by the so-called high-resolution shock-capturing schemes based upon Riemann solvers (Godunov-type schemes), even well inside the ultrarelativistic regime. Such central scheme can be straightforwardly applied to hyperbolic systems of conservation laws for which the characteristic structure is not explicitly known, or in cases where the exact solution of the Riemann problem is prohibitively expensive to compute numerically. Finally, we present comparisons with results obtained using various Godunov-type schemes as well as with those obtained using other high-resolution central schemes which have recently been reported in the literature.

description: Agent-based models (ABM) are used in many cases of policy assessment in agriculture. But the behavioural assumptions of these models consider farmers as myopic optimizing profit maximizers. In this contribution we compare the behaviour of myopic computer agents with the behaviour of students playing a multi period business management game. We aim to answer the question, how far are agent-based models valid to map “real” human behaviour, so that ABM can be used well for policy impact assessment.

Process simulation and catalyst development for biodiesel production
Creators: name: West, Alex Harris
Publisher: name: University of British Columbia
Year: 2010

description: Four continuous biodiesel processes were designed and simulated in HYSYS. The first two employed traditional homogeneous alkali and acid-catalysts. The third and fourth processes used a heterogeneous acid catalyst and a supercritical method, respectively, to convert a waste vegetable oil feedstock into biodiesel. While all processes were capable of producing biodiesel at high purity, the heterogeneous and supercritical processes were the least complex and had the smallest number of unit operations. Material and energy flows, as well as sized unit operation blocks, were used to conduct an economic assessment of each process. Total capital investment, total manufacturing cost and after tax rate-of-return (ATROR) were calculated for each process. The heterogeneous acid catalyst process had the lowest total capital investment and manufacturing costs, and had the only positive ATROR. Following the results of the process simulations, tin(II) oxide was investigated for use as a heterogeneous catalyst. Unfortunately, catalytic experiments showed no activity. Subsequently, a carbon-based acid catalyst was prepared by sulfonating pyrolysis char, and was studied for its ability to catalyze transesterification of vegetable oil. The catalyst showed only qualitative transesterification, but demonstrated good conversion in free fatty acid esterification. Experiments were designed to measure the effect of alcohol to oil (A:O) molar ratio, reaction time and catalyst loading on the sample. It was observed that free fatty acid (FFA) conversion increased with increasing A:O molar ratio, reaction time and catalyst loading. Conditions that yielded the greatest conversion were 18:1 A:O molar ratio, 3 hour reaction time, 5 wt.% catalyst, 76°C under reflux. The above conditions reduced the FFA content in a waste vegetable oil (WV0)-ethanol mixture from 4.25 wt.% to <0.5 wt.%. Under an 78:1 A:O molar ratio and identical conditions, the catalyst was able to reduce the FFA content of a WVO feedstock from 12.25 wt.% to 1 wt.%. The catalyst has potential to be used in a process converting a high FFA feedstock to biodiesel if the limitations to transesterification can be overcome. Otherwise, it will serve as an excellent catalyst for reducing the FFA content of feedstocks in a two-step acid and base conversion process.

description: India is the world largest producer of many vegetables but there still exists huge gap between per capita demand and supply due to enormous wastage during postharvest handling & marketing. The gaps between demand and supply are primarily due to ineffective market links and lack of consolidation on both the demand-side and supply-side. On the supply side, the government has agenda to promote modern cultivation practices, lower input costs and most importantly to counter fragmentation of farm lands by promoting FPOs (Farmer Produce Organisations) for collaborative farming. FPOs are commercial enterprises formed by partnering a minimum of 1000 farmers.

subject: knowledge measurement

subject: innovation course

description: The measurement of the knowledge change of employees as well as the transfer is discussed in this thesis. Although these two terms are often used synonymously, there is a difference between them. Learning is adapting to a situation whereas transfer is applying the knowledge to similar situations. There are many approaches to measuring learning success or transfer, most of which originate in educational science. In this thesis we consider the special case of innovation courses, where there are further requirements that must be met. Unfortunately, the existing frameworks are not designed for these requirements and are therefore not sufficient. An innovation course is a long-term course in which employees of companies are taught in a certain topic. Such an innovation course consists of several modules for which both the measurement of learning success and knowledge transfer for the participants must take place. To achieve this and to make the measurements repeatable and objective, we have developed a framework. We use the Design Science Approach to develop the framework. However, the goal is not to create a static artefact that can only be applied to the course of our case study, but to design a framework that is also easily adaptable and applicable in other innovation courses or in a similar environment. To test and improve the framework, we use it in four modules of the DigiTrans 4.0 innovation course. For three of the four modules of our case study, the difference between the knowledge before the module and at the end is statistically significant. We also create linear models to explain or predict the transfer. The models are created with and without heteroscedasticity adjustment. The results of the models are slightly different, but show a common trend, which originates from the same background formula. Since these characteristics are known in the literature of knowledge transfer, the framework created is well suited for measuring the transfer.

description: The optimisation of production plans is an important topic in agriculture, often related to diversification and specialisation as the classical instruments of coping with production risk. Although the measurement of embedded risk is often inaccurate, it is nevertheless necessary for decision making to describe the common behaviour of different variables in a model. Imprecisely defined relationships influence the “right” choice, why it is important to find a good approximation of the real circumstances. In financial science, copula functions are frequently used instead of correlation coefficients to model joint price behaviour, because of the possibility to link the marginal distributions on multifarious ways. By now, agricultural science makes less use of this method. This research uses the concept of “partly nested Archimedean copula” to model the relationship between different crop yields and compares it with a correlation based approach. The analysis focuses the differences of the approaches in the context of production planning and the use of weather derivatives.

description: The boson-fermion atomic bound states (composite fermion) and their roles for the phase structures are studied in a bose-fermi mixed condensate of atomic gas in finite temperature and density. The two-body scattering equation is formulated for a boson-fermion pair in the mixed condensate with the Yamaguchi-type potential. By solving the equation, we evaluate the binding energy of a composite fermion, and show that it has small T-dependence in the physical region, because of the cancellation of the boson- and fermion- statistical factors in the equation. We also calculate the phase structure of the BF mixed condensate under the equilibrium B+F -> BF, and discuss the role of the composite fermions: the competitions between the degenerate state of the composite fermions and the Bose-Einstein condensate (BEC) of isolated bosons. The criterion for the BEC realization is obtained from the algebraically-derived phase diagrams at T=0.

description: Previous literature on volatility links between food and energy prices is scarce and mainly based on parametric approaches. We assess this issue by using a semiparametric GARCH model recently proposed by Long et al. (2009), which is essentially a nonparametric correction of the parametric conditional covariance function. We focus on price links between crude oil, ethanol and sugar prices in Brazil. Results suggest strong volatility links between the prices studied. They also suggest that parametric approximations of the conditional covariance matrix may lead to misleading results and can be improved using nonparametric techniques.

description: Urban planning is increasingly data driven, yet the challenge of designing with data at a city scale and remaining sensitive to the impact at a human scale is as important today as it was for Jane Jacobs. We address this challenge with Urban Mosaic,a tool for exploring the urban fabric through a spatially and temporally dense data set of 7.7 million street-level images from New York City, captured over the period of a year. Working in collaboration with professional practitioners, we use Urban Mosaic to investigate questions of accessibility and mobility, and preservation and retrofitting. In doing so, we demonstrate how tools such as this might provide a bridge between the city and the street, by supporting activities such as visual comparison of geographically distant neighborhoods,and temporal analysis of unfolding urban development.

Rheology and processing of nanoclay loaded polyethylene resins
Creators: name: Devendra, Raghavendra
Publisher: name: University of British Columbia
Year: 2010

description: Several compounds were prepared by melt mixing various formulations of a linear low density polyethylene, a graft modified polyethylene and an organically modified clay, in a twin screw extruder. X-ray diffraction, transmission electron microscopy and rheology were used to characterize the extent of intercalation of the silicate galleries. Incorporation of minimum weight fraction of 2% clay and 50% maleated polyethylene was found to introduce radical changes in the rheological behaviour of the nanocomposites. Broadening peaks in X-ray diffraction indicated increasing dispersion of silicate nanolayers inside polymer as a function of graft modification. With higher incorporation of maleated polyethylene, solid-like response begins to appear at low frequencies indicating possible networking. Flow activation energy was found to decrease with incorporation of clay. Dual flow behaviour of the nanocomposites beyond the Newtonian plateau in the form of a filler-like flow at low shear rates and polymer-like shear thinning flow at high shear rates was observed. Changes in flow energy of activation with respect to clay and fusabond concentration are analysed. Relaxation spectra determined using a parsimonious model were found to extend to higher relaxation time scales with exfoliation. The Cox-Merz rule was found to fail over the whole range of shear rates for exfoliated compounds, indicating increased interactions in the matrix resulting in highly anisotropic distribution of individual silicate layers. Fusabond induces higher elasticity into the composite and increases the tensile stress growth function during melt elongation. Fusabond exhibits highly ductile failure as opposed to the brittle failure of polyethylene. Hence, fusabond is observed to contribute towards the ductility of the nanocomposite. A combination of fusabond and clay was found to be complementary in initiating strain hardening. The mechanical properties of the nanocomposites did not show an impressive change at low clay concentrations. A unique dip at 0.1 wt% clay loadings to complement its role in processing was followed by a steady increase with increasing clay concentration. While fusabond and higher levels of clay accounted for the increased toughness of nanocomposites, 0.1 wt% of clay decreased the toughness. There exists a threshold level of clay concentration above which the intercalation and exfoliation phenomena play a significant role in enhancing the mechanical properties.

description: The nested logit model has become an important tool for the empirical analysis of discrete outcomes. There is some confusion about its specification of the outcome probabilities. Two major variants show up in the literature. This paper compares both and finds that one of them (called random utility maximization nested logit, RUMNL) is preferable in most situations. Since the command nlogit of Stata 7.0 implements the other variant (called non-normalized nested logit, NNNL), an implementation of RUMNL called nlogitrum is introduced. Numerous examples support and illustrate the differences between both specifications.

description: This article discusses estimates of variance for two-stage models. We present the sandwich estimate of variance as an alternative to the Murphy–Topel estimate. The sandwich estimator has a simple formula that is similar to the formula for the Murphy–Topel estimator, and the two estimators are asymptotically equal when the assumed model distributions are true. The advantages of the sandwich estimate of variance are that it may be calculated for the complete parameter vector, and that it requires estimating equations instead of fully specified log likelihoods.

description: European farmers face increasing income uncertainty and the debate is growing on the role of insurance schemes and of public support in this field. This debate is further stimulated by the perspective of introducing instruments to cope with risk also in the Common Agricultural Policy. Therefore, there is a need for empirical analysis and tools aimed at providing empirical evidences on this subject. This paper applies a PMP modelling approach that takes into explicit consideration risk aversion behaviour to test the possibility to use it to assess the implications of participating in a insurance scheme. This is done by introducing a revenue insurance scheme into a model developed on a small group of crop farms in Italy. In particular, a quadratic mix integer programming approach has been developed in order to model the choice of participating or not in the proposed insurance scheme. The model has been than used to conduct simulations considering changes in the level of the insurance premium. The paper tries to assess the soundness of the proposed approach and to identify its limitations. The obtained results suggest that this could be a useful tool to investigate the impact of participating in insurance schemes on production patterns and farm profitability and the role of public support in this field.

description: AbstractContext: Little is known about the association between haptoglobin level and cardio-metabolic traits. A previous genome-wide association study identified rs2000999 in the HP gene as the stronger genetic contributor to serum haptoglobin level in European populations.Objective and design: We investigated the association of HP rs2000999 with serum haptoglobin and childhood and adult obesity in up to 540/697 and 592/691 Mexican cases and controls, respectively. Anthropometric and biochemical data were collected. Serum haptoglobin was measured by an immunoturbidimetry assay. HP rs2000999 was genotyped using the TaqMan technology. Mendelian randomization analysis was performed using the Wald and inverse variance weighting methods.Results: Haptoglobin level was positively associated with childhood and adult obesity. HP rs2000999 G allele was positively associated with haptoglobin level in children and adults. HP rs2000999 G allele was positively associated with childhood but not adult obesity. The association between HP rs2000999 and childhood obesity was removed after adjusting for haptoglobin level. In a Mendelian randomization analysis, haptoglobin level genetically predicted by HP rs2000999 showed a significant causal effect on obesity by the Wald and inverse variance weighting methods.Conclusion: Our data evidence for the first time a causal positive association between serum haptoglobin level and childhood obesity in the Mexican population. Our study contributes to the genetic elucidation of childhood obesity and proposes haptoglobin as an important biomarker and treatment target for obesity.

description: This paper examines if broadband Internet access (‘broadband’) developments enhance regional cohesion in ten New Member States (NMS-10) of the European Union. It focuses on broadband developments in these countries financed from Structural Funds (SF). The importance of their impacts is potential, but not automatic. The topic is well established theoretically, versus business. There is no conclusive evidence yet empirically. Broadband is perceived here as an essential part of ICT, enabling the spread and use of ICT. The paper analyses (1) the regional dimension of broadband access in the NMS-10, (2) the recognition of broadband-cohesion links by NMS-10 governments, and (3) the priority given to broadband in SF spending. The impact of broadband developments on cohesion is not presently monitored, however it would be essential in order to evaluate the effective use of public resources in the enhancement of regional cohesion.

description: Applications like Big Data, Machine Learning, Deep Learning and even other Engineering and Scientific research requires a lot of computing power; making High-Performance Computing (HPC) an important field. But access to Supercomputers is out of range from the majority. Nowadays Supercomputers are actually clusters of computers usually made-up of commodity hardware. Such clusters are called Beowulf Clusters. The history of which goes back to 1994 when NASA built a Supercomputer by creating a cluster of commodity hardware. In recent times a lot of effort has been done in making HPC Clusters of even single board computers (SBCs). Although the creation of clusters of commodity hardware is possible but is a cumbersome task. Moreover, the maintenance of such systems is also difficult and requires special expertise and time. The concept of cloud is to provide on-demand resources that can be services, platform or even infrastructure and this is done by sharing a big resource pool. Cloud computing has resolved problems like maintenance of hardware and requirement of having expertise in networking etc. An effort is made of bringing concepts from cloud computing to HPC in order to get benefits of cloud. The main target is to create a system which can develop a capability of providing computing power as a service which to further be referred to as Supercomputer as a service. A prototype was made using Raspberry Pi (RPi) 3B and 3B+ Single Board Computers. The reason for using RPi boards was increasing popularity of ARM processors in the field of HPC

description: In dieser Arbeit analysieren wir wie Studenten mit Hilfe von Micro-Tests und dynamischen Modellen direktes Feedback über ihren Lernfortschritt erhalten können. Zu Beginn geben wir eine Übersicht über unterschiedliche Terminologien und definieren häufig genutzte Begriffe, die für eine Diskussion heutiger E-Learning Systeme notwendig sind. Wir vergleichen eine Reihe von bekannten E-Learning Systemen wie Khan Academy, Coursera, edX, Udacity und Moodle und untersuchen welche Methoden diese Systeme implementieren um direktes Feedback an Studenten zu liefern. Wir kommen zu dem Schluß, dass ein eigenes E-Learning System die beste Wahl zur Evaluierung von direkten Feedback mittels Micro-Tests und dynamischen Modellen darstellt. Im Hauptteil der Arbeit beschreiben wir die Anforderungen eines solchen E-Learning Systems und stellen unsere eigene Implementierung vor. Unser Interactive Lecture Notes genanntes System implementiert ein interaktives Vorlesungsskriptum mit dynamischen Modellen und Micro-Tests und ermöglicht es Studenten direktes Feedback während des Lernprozesses zu erhalten. Wir haben unsere Implementierung in der Praxis im Kontext einer Lehrveranstaltung in drei Semestern mit Umfragen und Benutzerstatistiken evaluiert. Die Ergebnisse liefern eine erste Bestätigung für unsere Konzepte und zeigen, dass Micro-Tests und dynamische Modelle effektive Mechanismen für direktes Feedback sind.
description: The main goal of this thesis was to evaluate how micro-tests and dynamic models can provide instant feedback in e-learning systems. In the beginning of this thesis we present an overview of the terminology required for a thorough discussion of todays e-learning systems and platforms. We then present a comparison of the most common e-learning platforms in use; including Khan Academy, Coursera, edX, Udacity and Moodle and we analyze which methods each of these platforms implements in order to support instant feedback. Based on this comparison we motivate our reasons for implementing our own e-learning system as the most suitable solution to evaluate micro-tests and dynamic models. In the main part we present the requirements for such an e-learning system and introduce our own implementation. Our e-learning platform is called Interactive Lecture Notes and implements an interactive version of lecture notes that include dynamic models and micro-tests. It allows students to receive direct feedback during their learning process. We conducted three evaluations of our implementation in the context of a lecture and collected feedback via surveys and statistical usage data. The results seem to confirm our hypothesis that micro-tests and dynamic models are effective tools to provide instant feedback.

description: Sustainable rural development is one of the social, economic and territorial cohesion aspects of the European Union. In the current financial perspective 2007-2013 rural areas development is supported by the Common Agricultural Policy, which does not always contribute to improvement of their vitality and cohesion with urban areas. The main theses organising the analyses presented in this paper are as follows: The problem lies in the division of the funds into particular priorities of rural development and the rural development is still dominated by the agriculture approach. The European Commission and the Member States’ approaches to rural development focus on agricultural production and improving its conditions or environment protection. Cohesion Policy instruments intervention will be an essential condition for sustainable rural areas development. One of the key research issues concerned with rural areas development is territorial orientation in programming of the Structural Funds in the next financial perspective 2014-2020. Integrated rural development requires different instruments of development in order to stimulate non-agricultural economic, social and cultural activity of rural residents.

description: The study investigates the convergence of labour productivity in 204 NUTS2 regions of the EU-15 between 1995 and 2006. The main objective of our work was to assess whether and to what extent European Union (EU) policies (Regional Policy and Common Agricultural Policy) have been effective in promoting economic growth and fostering the process of convergence of EU regions. These policies can have an asymmetric spatial impact, even if some concrete steps have been taken to avoid an excessive concentration of costs or benefits. To verify the effects of EU policies we compare different scenarios: with/without EU policies. Under a methodological profile, we adopt the Solovian model proposed by Mankiw et al. (1992). For the estimates we used an econometric approach based on spatial filters with characteristics similar to Geographically Weighted Regression (GWR) in order to obtain consistent estimates of both the convergence parameters β and the impact of the conditioning variables, policy measures in particular. Our technique allows the estimation of different convergence rates for each region and management of both the presence of spatial spillovers and structural differences in the regional economies. The results indicate that global convergence rates are comparable to those obtained in some other studies, while local coefficients help to interpret the regional growth paths in a more realistic way. Finally, we utilise a quasi-experimental design, the Regression Discontinuity, for comparing the results of policy interventions, in terms of regional β-convergence rates, with a ‘counterfactual’ scenario.

description: Traditional techniques for Cyber-Physical Systems (CPS) security design either treat the cyber and physical systems independently, or do not address the specific vulnerabilities of real time embedded controllers and networks used to monitor and control physical processes. In this work, we develop and test an integrated model-based approach for CPS security risk assessment utilizing a CPS testbed with real-world industrial controllers and communication protocols. The testbed monitors and controls an exothermic Continuous Stirred Tank Reactor (CSTR) simulated in real-time. CSTR is a fundamental process unit in many industries, including Oil \& Gas, Petrochemicals, Water treatment, and nuclear industry. In addition, the process is rich in terms of hazardous scenarios that could be triggered by cyber attacks due to the lack of possible mechanical protection. The paper presents an integrated approach to analyze and design the cyber security system for a given CPS where the physical threats are identified first to guide the risk assessment process. A mathematical model is derived for the physical system using a hybrid automaton to enumerate potential hazardous states of the system. The cyber system is then analyzed using network and data flow models to develop the attack scenarios that may lead to the identified hazards. Finally, the attack scenarios are performed on the testbed and observations are obtained on the possible ways to prevent and mitigate the attacks. The insights gained from the experiments result in several key findings, including the expressive power of hybrid automaton in security risk assessment, the hazard development time and its impact on cyber security design, and the tight coupling between the physical and the cyber systems for CPS that requires an integrated design approach to achieve cost-effective and secure designs.
Non-Hermitian Multimode Interference

description: Multi-mode interference (MMI) and self-imaging are important phenomena of diffractive wave optics with major applications in optical signal processing, beam shaping and optical sensing. Such phenomena generally arise from interference of normal modes in lossless dielectric guiding structures, however the impact of spatially-inhomogeneous optical gain and loss, which break mode orthogonality and symmetries, has been overlooked. Here we consider MMI in non-Hermitian optical systems, either graded index or coupled optical waveguide structures with optical gain and loss, and reveal distinctive features, such as the absence of mirror images and strong-sensitivity of self-imaging to perturbations, making MMI in non-Hermitian waveguides of interest in optical sensing.

description: The study showed that selection for the high egg yield per hen housed is not always economically successful. Selection for the minimum cost(optimum level of egg yield)is economically, recommended. Less mortality rate leads to higher profit per L.E (Egyptian Pound)of costs, which reflects mainly a higher rate of culled layer-hens as a secondary output of the layer farms? Even though, mortality variation is due to the changes in the farm management and environmental conditions. Therefore, a selection policy in this direction is not economically feasible. Hibro-strain showed the lowest productive performance of a high instability level and high cost per egg. The Egyptian improved strain(Dokki-4), although it had a lower egg yield and a higher feed consumption per egg than the NHL strain, both showed the same cost level per egg. This reflects the effect of diminishing return concept on the costs of production.
