description: Agriculture is a provider of food and, to a certain extent, public goods such as biodiversity and landscape, but it can also have negative impacts on natural assets such as biodiversity and water quality. In addition to implementing policies that target individual farmers, different approaches are needed to promote collective action. The literature review and three New Zealand case studies (Sustainable Farming Fund, East Coast Forestry Project and North Otago Irrigation Company) have identified some findings including benefits and barriers of collective action and key factors for its success. Collective action should be given serious consideration in addressing agri-environmental problems.

description: Free Electron Laser (FEL) and Collective Atomic Recoil Laser (CARL) are described by the same model of classical equations for properly defined scaled variables. These equations are extended to the quantum domain describing the particle's motion by a Schrödinger equation coupled to a self-consistent radiation field. The model depends on a single collective parameter $\bar ρ$ which represents the maximum number of photons emitted per particle. We demonstrate that the classical model is recovered in the limit $\bar ρ\gg 1$, in which the Wigner function associated to the Schrödinger equation obeys to the classical Vlasov equation. On the contrary, for $\bar ρ\le 1$, a new quantum regime is obtained in which both FELs and CARLs behave as a two-state system coupled to the self-consistent radiation field and described by Maxwell-Bloch equations.
title: Optimized active redundancy with just-in-time duplication for safety critical mobile video streaming

Subjects: subject: SCTP

description: In safety-critical applications reliable delivery and timely arrival of data are equally important properties and yet known to be conflicting in real-time multimedia streaming. Whenever real-time systems depend on unreliable communication infrastructure like for instance IP networks, multihoming the availability of redundant network paths can provide fault tolerance and significantly increase overall systems reliability. This thesis examines different transmission strategies for multihomed setups to improve the reliability while at the same time considering latency and link efficiency requirements. Duplicating the entire stream onto multiple paths is simple but adds a significant data overhead. Retransmitting packets merely upon a detected loss, as offered by TCP, lowers data overhead but causes non-deterministic latency characteristics. Thus, the author of this thesis proposes Deadline Based Preemptive Retransmission (DPR), a transmission scheduling strategy that delays multipath packet duplication to meet the latency requirement just-in-time. This allows for more efficient link utilization by avoiding unnecessary data duplication. DPR is implemented as an extension to Concurrent Multipath Transmission (CMT), which is itself an extension of the Stream Control Transmission Protocol (SCTP). This thesis assesses the constraints and requirements of real-time transmission as well as the consequences of late packet arrival. This thesis presents new metrics to assess and quantify the performance of transmission strategies to satisfy the requirement of timely delivery of data as well as the penalty of introduced data overhead. The proposed transmission scheduling DPR and other investigated scheduling approaches are validated embedded in a multimedia-streaming pipeline with a modified version of GStreamer and an emulated network environment. The conducted experiments investigate the characteristics, performance and drawbacks of different duplication strategies under various network characteristics. The empirical analysis demonstrates the conspicuous benefits of DPR.
Wavelet based multivariate signal denoising using Mahalanobis distance and EDF statistics

description: A multivariate signal denoising method is proposed which employs a novel multivariate goodness of fit (GoF) test that is applied at multiple data scales obtained from discrete wavelet transform (DWT). In the proposed multivariate GoF test, we first utilize squared Mahalanobis distance (MD) measure to transform input multivariate data residing in M-dimensional space $\mathcal{R}^M$ to a single-dimensional space of positive real numbers $\mathcal{R}_+$, i.e., $\mathcal{R}^M \rightarrow \mathcal{R}_+$, where $M > 1$. Owing to the properties of the MD measure, the transformed data in $\mathcal{R}_+$ follows a distinct distribution. That enables us to apply the GoF test using statistic based on empirical distribution function (EDF) on the resulting data in order to define a test for multivariate normality. We further propose to apply the above test locally on multiple input data scales obtained from discrete wavelet transform, resulting in a multivariate signal denoising framework. Within the proposed method, the reference cumulative distribution function (CDF) is defined as a quadratic transformation of multivariate Gaussian random process. Consequently, the proposed method checks whether a set of DWT coefficients belong to multivariate reference distribution or not; the coefficients belonging to the reference distribution are discarded. The effectiveness of our proposed method is demonstrated by performing extensive simulations on both synthetic and real world datasets.

description: Die Maisanbaufläche in Deutschland ist in den vergangenen Jahren aufgrund der steigenden Anzahl Biogasanlagen und der guten Eigenschaften von Mais als Biogassubstrat stark ausgedehnt worden. Zur Begrenzung des Maisanbaus hat die Politik bereits Maßnahmen eingeleitet. Dazu zählt z.B. die Begrenzung des Maiseinsatzes in Biogasanlagen auf 60 Masseprozent und eine Förderung alternativer Biogassubstrate. Ein zurzeit viel diskutiertes Biogassubstrat sind spezielle Blühstreifenmischungen. Diese liefern eine hohe Methanausbeute je Hektar und weisen einen Zusatznutzen für die Umwelt auf. Mit einem Unternehmensplanspiel wird untersucht, ob Landwirte durch eine Belohnungs- und Bestrafungspolitik Blühstreifen in das Anbauprogramm aufnehmen. Die Ergebnisse zeigen, dass die Implementierung von Bestrafungs- und Belohnungspolitiken auf die Blühstreifenfläche eine anbaufördernde Wirkung hat. Außerdem zeigt sich, dass die Bestrafungspolitik eine stärkere verhaltenssteuernde Wirkung als die Belohnungspolitik hat, obwohl sich die Politikmaßnahmen nicht in ihrer Gewinnwirksamkeit unterscheiden. Des Weiteren weisen die Ergebnisse darauf hin, dass der Blühstreifenanbau durch soziodemografische Parameter in unterschiedlicher Weise beeinflusst wird.

description: We model the Galactic population of detached binaries that harbor black holes with (0.5-1.7) solar mass companions -- the remnants of case B mass-exchange that rapidly cross Hertzsprung gap after the termination of the Roche-lobe overflow or as He-shell burning stars. Several such binaries can be currently present in the Galaxy. The range of black hole masses in them is about 4 to 10 solar ones, the orbital periods are tens to hundreds day. The unique BH-binary LB-1 fits well into this extremely rare class of double stars.

description: The determinants of the demand for health services due to health problems is analyzed in the urban and rural areas of Brazil, based on the household survey from 1998. The variable health status of each individual was estimated as a function on the household’s infrastructure, individual characteristics, family income, etc., and the estimates were used as an explanatory variable in the demand for health services, to avoid endogeneity problems. The most important factor in determining health services, in urban and rural areas, was the individual’s health status. In urban areas, schooling was also important to reduce the demand for health services.
Lithium evolution in intermediate age and old open clusters: NGC 752 revisited

description: We present new high resolution spectroscopic observations of the intermediate age (~2 Gyr) open cluster NGC 752. We investigate the Li vs. Teff distribution and we obtain a new accurate determination of the cluster metallicity. We compare the results for NGC 752 with other intermediate age and old clusters spanning the age range from the Hyades (~0.6 Gyr) to NGC 188 (~6-8 Gyr). We find that NGC 752 has a solar iron content ([Fe/H]=+0.01+/-0.04), at variance with early reports of sub-solar metallicity. We find that NGC 752 is only slightly more Li depleted than the younger Hyades and has a Li pattern almost identical to that observed in the ~2 Gyr old IC 4651 and NGC 3680. As for the latter clusters, we find that NGC 752 is characterized by a tight Li vs. Teff distribution for solar-type stars, with no evidence for a Li spread as large as the one observed in the solar age solar metallicity M 67. We discuss these results in the framework of mixing mechanisms and Li depletion on the main sequence (MS). We conclude that the development of a large scatter in Li abundances in old open clusters might be an exception rather than the rule (additional observations of old clusters are required), and that metallicity variations of the order of ~0.2 dex do not affect Li depletion after the age of the Hyades.

description: We report field-induced magnetic phase transitions and transport properties of antiferromagnetic DyPtBi. We show that DyPtBi hosts a delicate balance between two different magnetic ground states, which can be controlled by a moderate magnetic field. Furthermore, it exhibits giant anomalous Hall effect (σ_A=1540 (ohm cm)^{-1},θ_{AHE} = 24%) in a field-induced Type-I spin structure, presumably attributed to the enhanced Berry curvature associated with avoided band-crossings near the Fermi energy and / or non-zero spin chirality. The latter mechanism points DyPtBi towards a rare potential realization of anomalous Hall effect in an antiferromagnet with face-center-cubic lattice that was proposed in [Physical Review Letters 87, 116801 (2001)].

description: Income transfers from family farm to nonagricultural sectors occurred due to imports to substitution policy. A way of compensating this segment could be compensated by an income stabilization policy that would improve the income distribution in the agricultural sector. Also it could assure a stable profitability to the farmers. The objective of this paper is to determine the benefits of an income stabilization policy implemented to the family farms producing rice, bean, corn and cassava. It is also objective of the research to determine the costs of this policy for commercial farmers. The methodology applies the Newbery’s and Stiglitz’s model, that considers the risk reduction with the income stabilization policy. This policy would increase income for the family farmers. The transfer benefits would overcome the efficiency benefits for family farmers and consumers. The benefits for the family farm would be larger than the costs for the commercial farm in the bean, cassava and corn markets. The benefits with this policy would overcome the costs in the bean and corn markets, but not in the rice and cassava markets.
Speech act theory and democratic communication : re-thinking the role of speech and the body in democratic theory and practice
Creators: name: Willson, Mark Adrian
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates a leading bias of democratic thought, both popular and academic: that speech is the only and best modality of political action in democracy. Through the texts of J.L. Austin, Pierre Bourdieu and Hannah Arendt I investigate exclusionary consequences of this dimension of contemporary democratic life, highlighting how an emphasis on speech as the primary, and perhaps sole, legitimate form of democratic participation threatens to impede the contributions of groups that lack access to forms of speech that are taken seriously, and positions from which speech gets heard. To illuminate non-speech oriented dimensions of democratic politics that are typically treated as illegitimate, or not thought about at all, I link this work on speech theory and democratic theory to literature that explores the body itself as another vehicle for communication and site of political action. With reference to the works of Judith Butler, I investigate the body as a site of communicative power for social actors whose speech contributions tend to be unauthorized by dominant norms and undervalued due to social prejudices. With reference to these strands of thought, I emphasize the central role of bodily acts in a continuous widening of access to deliberative democratic processes, and I argue that such acts should be recognized as having a greater role in, and deserve greater attention in studies of, democratic communication and struggles for recognition.

description: We show that the protein-protein interaction networks can be surprisingly well described by a very simple evolution model of duplication and divergence. The model exhibits a remarkably rich behavior depending on a single parameter, the probability to retain a duplicated link during divergence. When this parameter is large, the network growth is not self-averaging and an average vertex degree increases algebraically. The lack of self-averaging results in a great diversity of networks grown out of the same initial condition. For small values of the link retention probability, the growth is self-averaging, the average degree increases very slowly or tends to a constant, and a degree distribution has a power-law tail.

Military preparedness in a new security environment : the Canadian army reserve’s contribution to public safety and domestic security
Creators: name: Ward, Russell V. J.
Publisher: name: University of British Columbia
Year: 2009

description: Military Preparedness in a New Security Environment: The Canadian Army Reserve's Contribution to Public Safety and Domestic Security addresses the Reserve's response to Canada's domestic security needs in the current security environment. The security environment is evolving, which has led to increasing constraints and the search for evolving security solutions for Western national governments, including a greater use of the Reserve. However, certain tensions inhibit the twin-track contributions of the Reserve to both domestic and international operations, arising from issues such as role definition, buy-in, and resource commitment. The "Canadian solution" o f having the Reserve "muddle through" these issues and follow both roles will inevitably need to change if the Reserve is to effectively serve Canadians in the future, be that internationally or domestically. The methods employed include the analysis of existing literature addressing the evolving security environment, concepts of civil-military relations, and recent Canadian national security policies, combined with a presentation of the Army Reserve, and a comparative study with key Commonwealth counterparts. Thus, at a conceptual level, at the Canadian level, and at the level of Canada's international partners, it became apparent that there are tensions between a domestic and international role for the Reserve which could create problems for the Reserve's future. In practice, the methodology consisted of the analysis of academic and government primary and secondary sources as well as drawing upon the author's interviews with individuals of relevant expertise or experience.

description: Polar optical-phonon modes are derived analytically for spheroidal quantum dots with wurtzite crystal structure. The developed theory is applied to a freestanding spheroidal ZnO quantum dot and to a spheroidal ZnO quantum dot embedded into a MgZnO crystal. The wurtzite (anisotropic) quantum dots are shown to have strongly different polar optical-phonon modes in comparison with zincblende (isotropic) quantum dots. The obtained results allow one to explain and accurately predict phonon peaks in the Raman spectra of wurtzite nanocrystals, nanorods (prolate spheroids), and epitaxial quantum dots (oblate spheroids).

We investigate the behavior of the Hall component of the electric current density which appears due to the trigonal warping of the valleys in k-space. We calculate the spectrum of the current density and study its dependence on the electron effective lifetime and density in the sample. We distinguish between the drift and diffusive components of the current and show, which components turn out predominant. Furthermore, we compare the effect of the Rayleigh and Bluestein-Gulyaev acoustic waves, which appear if the sample is located on a piezoelectric substrate.

description: Durch den Digitalisierungsgap in der Baubranche gibt es ein großes Potential zur Prozessoptimierung. Neue digitale Technologien, wie das Building Information Modelling (BIM), werden immer mehr von den Stakeholdern in diesem Bereich angenommen. Die Blockchain auf der anderen Seite ist eine sehr neue und innovative Technologiedomäne, welche in den letzten Jahren extrem gewachsen ist und in der momentan die passenden Use Cases für die neue Technologie gesucht werden. Im Speziellen das noch neuere Untergebiet der Smart Contract Entwicklung hat die Vision von vielen neuen Anwendungen beflügelt, wobei nicht immer klar ist, ob diese so wie in der Vorstellung umgesetzt werden können, beziehungsweise ob dabei überhaupt ein Bedarf für eine dezentrale Lösung besteht. Bei einem Bauprojekt müssen Änderungen in einem BIM Modell immer vom passenden Stakeholder freigegeben werden. Deshalb haben wir in dieser Arbeit BIM Modelle, welche in einem Git Repository verwaltet werden, mit einem Freigabeverwaltungsworkflow, welcher als ein Smart Contract auf der Ethereum Blockchain umgesetzt wurde, kombiniert. Dadurch soll der Workflow transparent, nachvollziehbar und dessen Ergebniss im Nachhinein unveränderlich werden. Das Ziel dieser Arbeit ist es einen Smart Contract Prototypen zu erstellen und diesen mit anderen (off-chain) Lösungen im Bezug auf Kosten und Sicherheit zu vergleichen.
description: There is a big potential for process optimizations, due to the digitalization gap in the construction business. New digital technologies, as the Building Information Modelling (BIM), are increasingly being adapted by the stakeholders in this area. On the other hand, blockchain is a very new and innovative technology domain which has grown immensely in the last several years, and where people are now trying to find the right use-cases. Especially, the even newer field of smart contract development has opened the door for a large amount of possible applications, where it is neither clear if these can actually be implemented as envisioned, nor if there is even a need for a decentralized solution at all. In a construction project, changes on BIM models are only to be approved by the appropriate stakeholder. Therefore, we have combined the BIM models, which are stored using a Git repository, with a release management workflow, which is realised as a smart contract on the Ethereum blockchain.This enables the workflow to be transparent, traceable and its results to be immutable. The goal of this work is to create a prototype and compare it to other (off-chain) solutions and to evaluate if an application of a combination of BIM and blockchain yields an advantage in terms of costs and security.

description: A simple mechanical spring-block model is introduced for studying magnetization phenomena and in particularly the Barkhausen noise. The model captures and reproduces the accepted microscopic picture of domain wall movement and pinning. Computer simulations suggest that this model is able to reproduce the main characteristics of hysteresis loops and Barkhausen jumps. In the thermodynamic limit the statistics of the obtained Barkhausen jumps follows several scaling laws, in qualitative agreement with the experimental results. The simplicity of the model and the invoked mechanical analogies makes it attractive for computer simulations and pedagogical purposes.

description: Diese Diplomarbeit stellt eine Software-Visualisierung vor, welche der Analyse von Software-Qualitätstrends und der Ursachenforschung für mögliche Änderungen eines Trends dient. Die Idee basiert auf spezifischen Informationsbedürfnissen von Software-Entwicklern. Diese Informationsbedürfnisse wurden durch eine Analyse aktueller Literatur erhoben. Bereits existierende Software-Visualisierungen zeigten, dass es hilfreich ist, sehr granulare Software-Qualitätstrends mit Versionsunterschieden von Quelltext zu verknüpfen. Dies ermöglicht es, einfacher auf relevante Quelltextänderungen zuzugreifen als dies mit bisherigen Software-Visualisierungen möglich ist. Außerdem werden dadurch die zuvor genannten Informationsbedürfnisse erfüllt. Eine auf Szenarien basierte Evaluierung durch Experten hat gezeigt, dass der in dieser Arbeit vorgeschlagene Prototyp einer Software-Visualisierung das Nachvollziehen von Quelltextund Qualitätsänderungen erleichtert und einen Mehrwert gegenüber aktuellen Lösungen bietet. Des Weiteren wurden die Szenarien durch Experten bewertet, um die praktische Relevanz des entwickelten Prototyps herauszustreichen. Auf der System Usability-Skala wurde der Prototyp mit “Gut” bewertet.
description: This masters thesis proposes a software visualization that aims at analyzing software quality metric trends and identifying possible causes of change. The idea is based on the specific information needs of software developers that are hard to satisfy. These information needs were found with an analysis of the state-of-the-art literature. A review of existing software visualization tools revealed that it is beneficial to combine fine-grained quality metric trends with code difference views based on data from version control repositories. This combination allows for easier access to relevant code changes compared to existing software visualization solutions and satisfies some of the previously mentioned information needs. A scenario-based expert evaluation revealed that the proposed software visualization prototype makes the comprehension of codeand code-quality changes easier and has added value compared to current solutions. Experts were also asked to rate selected use cases of the prototype to emphasize its practical usefulness. On the System Usability Scale, the prototype is rated “Good”.

description: The structural properties of polydisperse hard spheres in the presence of a hard wall are investigated via Monte Carlo simulation and density functional theory (DFT). Attention is focussed on the local density distribution $ρ(σ,z)$, measuring the number density of particles of diameter $σ$ at a distance $z$ from the wall. The form of $ρ(σ,z)$ is obtained for bulk volume fractions $η_b=0.2$ and $η_b=0.4$ for two choices of the bulk parent distribution: a top-hat form, which we study for degrees of polydispersity $δ=11.5%$ and $δ=40.4%$, and a truncated Schulz form having $δ=40.7%$. Excellent overall agreement is found between the DFT and simulation results, particularly at $η_b=0.2$. A detailed analysis of $ρ(σ,z)$ confirms the presence of oscillatory size segregation effects observed in a previous DFT study (Pagonabarraga {\em et al.}, Phys. Rev. Lett. {\bf 84}, 911 (2000)). For large $δ$, the character of these oscillation is observed to depend strongly on the shape of the parent distribution. In the vicinity of the wall, attractive $σ$-dependent depletion interactions are found to greatly enhance the density of the largest particles. The local degree of polydispersity $δ(z)$ is suppressed in this region, while further from the wall it exhibits oscillations.

description: A quantitative understanding of the dominant mechanisms that govern the generation and decay of the counter-rotating vortex pair (CVP) produced by yawed wind turbines is needed to fully realize the potential of yawing for wind farm power maximization and regulation. Observations from large eddy simulations (LES) of yawed wind turbines in the turbulent atmospheric boundary layer and concepts from the airplane trailing vortex literature inform a model for the shed vorticity and circulation. The model is formed through analytical integration of simplified forms of the vorticity transport equation. Based on an eddy viscosity approach, it uses the boundary layer friction velocity as the velocity scale and the width of the vorticity distribution itself as the length scale. As with the widely used Jensen model for wake deficit evolution in wind farms, our analytical expressions do not require costly numerical integration of differential equations. The predicted downstream decay of maximum vorticity and total circulation agree well with LES results. We also show that the vorticity length scale grows linearly with downstream distance and find several power laws for the decay of maximum vorticity. These results support the notion that the decay of the CVP is dominated by gradual cancellation of the vorticity at the line of symmetry of the wake through cross-diffusion.

description: Im Mai 2011 stellte Deutschland als einer der letzten EU-Staaten die Arbeitnehmerfreizügigkeit für Bürger der acht neuen EU-Mitgliedstaaten her. Nach Aufhebung der Arbeitserlaubnispflicht wurde ein zunehmender Wettbewerb zwischen verschiedenen Branchen um Saisonarbeitskräfte aus diesen Ländern erwartet. Für die Landwirtschaft, die bislang schon Saisonarbeitskräfte aus Osteuropa einsetzen konnte, ergeben sich damit neue Herausforderungen im Bereich des Personalmanagements. Vor diesem Hintergrund analysiert diese Studie, welche Faktoren Saisonarbeitskräfte bei der Arbeitsplatzwahl beeinflussen, welche Anforderungen die Arbeitskräfte an die Saisonarbeit stellen und welche Implikationen für das Personalmanagement in landwirtschaftlichen Betrieben sich daraus ableiten lassen.

description: We study the effect of the competition between disorder and stress enhancement in fracture processes using the local load sharing fiber bundle model, a model that hovers on the border between analytical tractability and numerical accessibility. We implement a disorder distribution with one adjustable parameter. The model undergoes a localization transition as a function of this parameter. We identify an order parameter for this transition and find that the system is in the localized phase over a finite range of values of the parameter bounded by a transition to the non-localized phase on both sides. The transition is first order at the lower transition and second order at the upper transition. The critical exponents characterizing the second order transition are close to those characterizing the percolation transition. We determine the spatiotemporal correlation function in the localized phase. It is characterized by two power laws as in invasion percolation. We find exponents that are consistent with the values found in that problem.

description: In public administration, obtaining accurate data is essential for effective decision-making and policy design. However, the available data are often imperfect. A "Smart State" approach, as we define it at Fundar, recognizes the value of data, its organization, classification, the incorporation of alternative sources of information and the promotion of interoperability, which contribute to improving the quality of data and public policies. This presentation seeks to illustrate this based on a selection of cases and applications of State organizations in Argentina. A work from the Data area of www.fund.ar.

description: We report the spectroscopic confirmation of a compact \lya emitting galaxy at $z=5.721$. A FORS2 spectrum of the source shows a strong asymmetric line with a flux of 5$\times10^{-17}$ erg s$^{-1}$ cm$^{-2}$, making it one of the brightest \lya emitting galaxies at this redshift, and a line-of-sight velocity dispersion of 400 km s$^{-1}$. We also have a tentative detection of a second, narrower component that is redshifted by 400 km s$^{-1}$ with respect to the main peak. A FORS2 image shows that the source is compact, with a FWHM of 0\farcs5, which corresponds to 3.2 kpc at this redshift. This source is a brighter example of \object{J1236.8+6215} \citep{Dawson02}, another \lya\ emitting galaxy at $z\sim5.2$.

description: Detecting emergency vehicles arrival on roads has been the focus for many researchers. It is quite important to detect the emergency vehicles (e.g; ambulance) arrival to traffic light to give the green light for it to pass through. Many researchers have suggested and patented emergency vehicles detection systems however, according to our knowledge, none of them considered solving the effect of giving extra green time to a road while the queues are being built on others. This paper considers the problem of finding a better traffic light phase plan to stabilize/recover the situation at an effected intersection after solving an emergency vehicle existence. A hardware setup and a novel messaging protocol have been suggested to be set on roads and vehicles to collect roads real time data. In addition, a novel decision making protocol has been created to make the use of the collected data for making a better traffic light phase plan for an intersection. The phase plan has two main decisions to be made; which light has a higher priority to be green in the next phase, and how long the green phase should be. After simulating the proposed system using our customized simulator written in Matlab programing language and comparing its performance with other related works, significant enhancements have been observed in terms of stabilizing the queue lengths at an intersection after solving an emergency case.

description: This study analyses the effect of social capital on the volume of contracts in the rural credit market. It discusses how social capital contributes to the reduction of financial intermediation’s transaction costs. A logit regression model was used to empirically test the effect of social capital on the volume of rural credit. The results indicate that the level of social capital affects the amount of rural credit. Thus, incentives to further increase and maintain social capital would increment the efficiency of financial intermediation and, as a consequence, help the rural sector’s development.

description: We investigate the dissipative mechanisms exhibited by creased material sheets when subjected to mechanical loading, which comes in the form of plasticity and relaxation phenomena within the creases. After demonstrating that plasticity mostly affects the rest angle of the creases, we devise a mapping between this quantity and the macroscopic state of the system that allows us to track its reference configuration along an arbitrary loading path, resulting in a powerful monitoring and design tool for crease-based metamaterials. Furthermore, we show that complex relaxation phenomena, in particular memory effects, can give rise to a non-monotonic response at the crease level, possibly relating to the similar behavior reported for crumpled sheets. We describe our observations through a classical double-logarithmic time evolution and obtain a constitutive behavior compatible with that of the underlying material. Thus the lever effect provided by the crease allows magnified access to the material's rheology.

description: Freespace detection is an essential component of visual perception for self-driving cars. The recent efforts made in data-fusion convolutional neural networks (CNNs) have significantly improved semantic driving scene segmentation. Freespace can be hypothesized as a ground plane, on which the points have similar surface normals. Hence, in this paper, we first introduce a novel module, named surface normal estimator (SNE), which can infer surface normal information from dense depth/disparity images with high accuracy and efficiency. Furthermore, we propose a data-fusion CNN architecture, referred to as RoadSeg, which can extract and fuse features from both RGB images and the inferred surface normal information for accurate freespace detection. For research purposes, we publish a large-scale synthetic freespace detection dataset, named Ready-to-Drive (R2D) road dataset, collected under different illumination and weather conditions. The experimental results demonstrate that our proposed SNE module can benefit all the state-of-the-art CNNs for freespace detection, and our SNE-RoadSeg achieves the best overall performance among different datasets.
