description: The appearance of consumers groups increasingly concerned about the quality of food products, together with an increasingly competitive environment and domestic saturated markets, has led companies to achieving differentiated quality. The wine sector is immersed in this situation. Valuation of this differentiation by consumers will not happen by complying with certain standards or technical specifications, but rather it has to be perceived by consumers. Unlike experts, consumers cannot easily know which properties are intrinsic to products, which are those that give them their quality. There is, thus, a problem of uncertainty regarding the quality of products. This problem becomes more complex when consumers are faced with many alternatives of a similar perceived quality, which makes them have to decide on one without being completely sure. This problem is evident in the wine market. To solve this issue, Signalling Theory has investigated the variables used by consumers to infer quality. Among these variables are price, guarantees, origin, advertising, packaging design and brand. From the consumer point of view, the most reliable signal is the brand. Due to the territory image was earning more and more equity; an opportunity to differentiate wine emerged for these regions, which was the creation of appellations of origin. Thus, some producers of a same region or territory can collaborate and establish a joint offer which permits to differentiate a typical production. Therefore, the appellation of origin or, in our case, the collective brand, will have the basic objective of signalling differentiation. The aim of this work is therefore to ascertain the value that the collective brand, as a signal, provides for end consumers. In order to respond to this question, a field study consisting of a personal survey was carried out in 2006 on a sample of 296 Spanish purchasers and/or consumers of quality wine. Results reveal that the collective brand, as a signal, allows consumers to infer quality, but also it improves perception of the intrinsic attributes of the product, which some authors have called the halo effect.

description: In relation to types and advantages of computer network topologies, in this research work, availability and cost analysis of complex computer network is considered to focus on a tree topology network that has four subsystems A,B,C and D and all the subsystems are figured in series and parallel configuration, the subsystem A and B served as computer servers together with two units each and are working 1-out-of-2: G/F policy while C and D subsystems both has three units and are working in 2-out-of-3: G/F scheme, A and B attached to subsystems C and D respectively. The system has two types of failure, degraded (partial failure) or complete failed states. The system is analyzed using supplementary variables techniques and Laplace transform. Copula family and general distribution are employed to restore the complete failed and partial failed states respectively. Computed results have been highlighted by the means of tables and graphs.

description: With the advent of gravitational wave astronomy, techniques to extend the reach of gravitational wave detectors are desired. In addition to the stellar-mass black hole and neutron star mergers already detected, many more are below the surface of the noise, available for detection if the noise is reduced enough. Our method (DeepClean) applies machine learning algorithms to gravitational wave detector data and data from on-site sensors monitoring the instrument to reduce the noise in the time-series due to instrumental artifacts and environmental contamination. This framework is generic enough to subtract linear, non-linear, and non-stationary coupling mechanisms. It may also provide handles in learning about the mechanisms which are not currently understood to be limiting detector sensitivities. The robustness of the noise reduction technique in its ability to efficiently remove noise with no unintended effects on gravitational-wave signals is also addressed through software signal injection and parameter estimation of the recovered signal. It is shown that the optimal SNR ratio of the injected signal is enhanced by $\sim 21.6\%$ and the recovered parameters are consistent with the injected set. We present the performance of this algorithm on linear and non-linear noise sources and discuss its impact on astrophysical searches by gravitational wave detectors.

description: The lensing and Einstein ring at the core of the galaxy cluster Abell 3827 are reproduced in the modified gravity theory MOG. The estimated effective lensing mass $M_L=(1+α)M_b=5.2\times 10^{12} M_\odot$ within $R=18.3$~kpc for a baryon mass $M_b=1.0\times 10^{12} M_\odot$ within the same radius produces the observed Einstein ring angular radius $θ_E=10''$. A detailed derivation of the total lensing mass is based on modeling of the cluster configuration of galaxies, intracluster light and X-ray emission. The MOG can fit the lensing and Einstein ring in Abell 3827 without dark matter as well as General Relativity with dark matter.

description: Increasing demands on joining technology in terms of lightweight construction and component complexity require the further development of technologically suitable welding processes. Friction stir welding is a promising alternative to conventional fusion welding processes. The central element of this technology is a tool consisting of a shoulder and a probe, which generates a friction-induced heat input through rotation and pressure. The process is used in automotive, shipbuilding and aerospace applications due to its excellent mechanical material properties, which are similar to those of the base material. However, FSW is subject to process-specific challenges, including comparatively high process forces, high clamping requirements and tribological stresses during welding, as the process involves constant contact between the tool and the workpiece. As the welding process progresses, the tribochemical stresses cause the tool shape and material to change. The result is premature tool failure and reduced process reliability. While previous investigations have focused on increasing wear resistance by selecting a suitable coating system and varying tool geometries, the aim of this study is to adapt the surface of the welding probe by changing the microgeometry and microstructure. Based on the current state of the art, the present work investigates the influence of the welding probe by adapting the microgeometry and microstructure and shows the extent to which tool wear, weld seam quality and behaviour in the welding process can be influenced. By analogy with machining, individual welding probes will be prepared by drag finishing and the effect on tool geometry and wear will be demonstrated. In addition, a feasibility study will be carried out on the thread rolling of welding probes with metric threads. This process, which is used to adjust the microstructure, will show whether production by rolling is feasible and to what extent the surface finish of the rolled welding probes differs from that of conventionally produced ones. The investigations were carried out using a force-controlled robotic welding setup to weld 5 mm thick AA 6060 T66 sheets. A Kistler multicomponent dynamometer type 9139AA was used to measure the cartesian forces in the x-, y- and z-directions. The weld seam properties of the initial and the optimized tool designs were determined by visual and metallographic inspection and tensile tests to DIN EN ISO 25239-5.

Discuss Data – an Open Repository for Research and Data Communities

Publisher: name: Zenodo
Year: 2024

description: In this poster, we show how the Discuss Data research data platform is being expanded to include a “community space” for the digital humanities (DH). Discuss Data enables and promotes contextualized discussion about the quality and sustainability of research data directly on the object.

Current standards and the digitization of existing processes require structures to enable sustainable development models. This applies in particular to the quality of research data, which is becoming increasingly important in the academic debate.

Discuss Data offers a platform for this. In addition to the information technology management, archiving and provision of data, Discuss Data also contextualizes data through curated discussion. The platform addresses individual communities and offers them a subject-specific discussion space and, in the long term, community-specific tools. Communities are not to be equated with disciplines, but are rather interest groups on specific issues or data materials.

Following the introduction of the first community space for the research community on Eastern Europe, South Caucasus and Central Asia in 2020, 121 datasets were published and 141 users have registered (as of 28.11.23). However, the discussion function provided by Discuss Data has been used comparatively little so far. This discussion culture, which is quite common at conferences and reviews and is extremely important from a technical perspective, has not yet become established, despite the positive attitude towards it.

Digital method and source criticism has become one of the central challenges of the digital humanities. Until now, research data has generally been published on institutional repositories or platforms such as Zenodo, but without the kind of quality control that is customary for journal articles. As a result, datasets often remain unused for further processing because it remains unclear what quality the research data has and what it might be suitable for.

From the experience of the first funding phase of Discuss Data, it has become clear that more energy must be put into attracting data curators in order to ensure that the community spaces are supported by the community in the long term. Positive examples are needed for this. For example, the integration of discussions as micropublications could help to demonstrate the individual added value.

description: A deep understanding of metal deformation processes is essential for producing complex geometries in many industrial applications. Although simulations using Finite Element Methods (FEM) have helped in steering toward that goal, they are particularly time-consuming for large 3D meshes. Searching for the process parameters that lead to the desired shape of a metal part can become extremely expensive in terms of man-hours and computational resources. We investigated how machine learning models, especially deep neural networks, can help in speeding up the design process of deep drawing and joining processes by allowing a fast interpolation of FEM simulations from minutes or hours to seconds. In this study, inspired by implicit representations of 3D objects using neural networks, an implicit approach is used to predict local properties such as the thickness of the metal sheet, its thinning, and plastic strain, using solely the process parameters defining the experiment. We observe that the low number of trainable parameters of the predicting model ensures a generalization to unseen process parameters and ultimately allows for a reliable fast inspection of the processes.

title: Novel mouse models of Col-1 related overlap syndrome, with late onset osteoarthritis
Creators: name: Blease, Andrew Michael
Publisher: name: The Open University
Year: 2021

description: Collagen I is a member of the Collagen superfamily of proteins, the proteins most abundant in mammals, and an essential component of bones, teeth, skin and connective tissues including ligaments and tendons. COL1A1 and COL1A2 are the genes that code for the collagen I alpha chains, α1 and α2 respectively. Collagen I is a heterotrimer of these two alpha chains, formed of two α1 and one α2 chains. Diseases resulting from genetic mutations in COL1A1 and COL1A2, include osteogenesis imperfecta (OI) and Ehlers-Danlos syndrome (EDS), however, mutations in these genes have not been implicated in the development of osteoarthritis (OA). At MRC Harwell Institute, large-scale mutagenesis screens, including the Harwell Ageing Screen, have been used to identify novel models of disease and establish links between genes and diseases. The mutagenised mouse lines MP-107 and TM44 were identified in such screens, exhibiting early-onset mild bone abnormalities at the pelvis and elbow. These animals subsequently developed late-onset phenotypes including abnormal bone growth at the knee and OA. Genetic mapping and sequencing revealed that MP-107 and TM44, contained mutations in Col1a2 and Col1a1 respectively, which correspond to the genes COL1A2 and COL1A1 in humans. The MP-107 mutation was a T to A transversion at position 4521226 of Chromosome 6 resulting in alternative splicing at exon 22 of Col1a2. The TM44 mutation was a C to T transition at position 94836670 of Chromosome 11 resulting in a premature stop codon in exon 31 of Col1a1. Extensive phenotyping analysis revealed that the bone abnormalities observed in these lines are a result of an OI phenotype. Evidence of an EDS phenotype was also identified in the line MP-107, indicating that MP-107 is likely a model of Col-1 related overlap syndrome, a proposed EDS subtype exhibiting aspects of OI and EDS. Collagen I related changes to the joint tissues is likely the cause of the OA phenotypes. The project has the potential to enhance understanding of both the development of Col-1 related overlap syndrome and OA, and possible targets for therapy.

description: With the new handheld goSCOUT3D sensor system, the entire surface of complex industrial machinery spanning several meters can be captured three-dimensionally within a matter of minutes. In addition, a comprehensive photo collection is registered and precisely assigned to the corresponding 3D object points in one hybrid 2D/3D model. At the basis of the robust 3D digitization are the measuring principles of photogrammetric reconstruction using a high-resolution color camera and simultaneous localization and imaging using a tracking unit. Following image acquisition, the process leading to generation of the complete hybrid model is fully automated. Under continuous movement of the sensor head, up to six images per second and a total of up to several thousand images can be recorded. Those images are then aligned in 3D space and used to reconstruct the 3D model. Results regarding accuracy measurements are presented as well as application examples of digitized technical machinery under maintenance and inspection.

description: Evaluation of reliability is most important when we have to check the availability of supply in any distribution system. A basic reliability index which is of importance is failure rate of the distribution system. In this paper evaluation of system data i.e. failure rate which is one of the important basic reliability indices of Roy Billinton test system (RBTS) Bus-2 distribution system for educational purpose is done. This paper also evaluates the reliability of each and every feeder section of the RBTS. The mean time to failure (MTTF) of the feeders is also evaluated for each and every feeder section of the distribution system of the RBTS Bus-2 distribution system. The evaluated system data and various reliability indices can be used for educational purpose.

description: We investigate the origin of the resistance fluctuations of mesoscopic samples, near transitions between Quantum Hall plateaus. These fluctuations have been recently observed experimentally by E. Peled et al. [Phys. Rev. Lett. 90, 246802 (2003); ibid 90, 236802 (2003); Phys. Rev. B 69, R241305 (2004)]. We perform realistic first-principles simulations using a six-terminal geometry and sample sizes similar to those of real devices, to model the actual experiment. We present the theory and implementation of these simulations, which are based on the linear response theory for non-interacting electrons. The Hall and longitudinal resistances extracted from the Landauer formula exhibit all the observed experimental features. We give a unified explanation for the three regimes with distinct types of fluctuations observed experimentally, based on a simple generalization of the Landauer-Buttiker model. The transport is shown to be determined by the interplay between tunneling and chiral currents. We identify the central part of the transition, at intermediate filling factors, as the critical region where the localization length is larger than the sample size.

description: Policy research on African agriculture is long on prescriptions for what needs to be done to spur agricultural growth but short on how such prescriptions might be implemented in practice. What explains this state of affairs? What might be done to correct it, and, most important, how? This paper addresses these questions via a comprehensive review and assessment of the literature on the role and impact of research in policy processes. Six major schools of thought are identified: the rational model; pragmatism under bounded rationality; innovation diffusion; knowledge management; impact assessment; and evidence-based-practice. The rational model—with its underlying metaphor of a “policy cycle” comprising problem definition and agenda setting, formal decision making, policy implementation, evaluation, and then back to problem definition and agenda setting, and so on—has been criticized as too simplistic and unrealistic. Yet it remains the dominant framework guiding attempts to bridge gaps between researchers and policy makers. Each of the other five schools relaxes certain assumptions embedded within the rational model—e.g., wholly rational policy makers, procedural certainty, well-defined research questions, well-defined user groups, well-defined channels of communication. In so doing, they achieve greater realism but at the cost of clarity and tractability. A unified portable framework representing all policy processes and capturing all possible choices and tradeoffs faced in bridging research, policy, and practice does not currently exist and is unlikely ever to emerge. Its absence is a logical outcome of the context-specificity and social embeddedness of knowledge. A fundamental shift in focus from a “researcher-as-disseminator” paradigm to a “practitioner-as-learner” paradigm is suggested by the literature, featuring contingent approaches that recognize and respond to context-specificity and social embeddedness. At bottom, the issue is how to promote “evidence-readiness” among inherently conservative and pragmatic policy makers and practitioners and “user-readiness” among inherently abstraction-oriented researchers.

Epitaxial bilayer structures of half metal--colossal magnetoresistive La$_{\mathrm{2/3}}$Ca$_{\mathrm{1/3}}$MnO$_{\mathrm{3}}$ (HM--CMR) and high--$T_{\mathrm{c}}$ superconducting YBa$_{\mathrm{2}}$Cu$_{\mathrm{3}}$O$_{\mathrm{7-δ}}$(HTSC) are grown on SrTiO$_3$ (100) single--crystalline substrates using pulsed laser deposition. Magnetization $M$(T) measurements show the coexistence of ferromagnetism and superconductivity in these structures at low temperatures. Using the HM--CMR layer as an electrode for spin polarized electrons, we discuss the role of spin polarized self injection into the HTSC layer. The experimental results are in good agreement with a presented theoretical estimation, where the spin diffusion length $ξ_{\mathrm {FM}}$ is found to be in the range of $ξ_{\mathrm{FM}} \approx$ 10 nm.

description: Zambia is one of the poorest countries in Africa. Despite substantial reform during the 1990s, the economy has remained heavily dependent on urban-based mining. Copper's long-standing dominance led to a strong bias against agriculture, which undermined the sector's growth and export potential. Consequently poverty has remained concentrated within marginalized rural areas. Recent volatility in copper exports and growing foreign debt indicate the need for further economic diversification and pro-poor growth. These needs have been clearly identified in the country's Poverty Reduction Strategy Paper (PRSP), which outlines a series of policy objectives aimed at combating HIV/AIDS, reversing the deterioration of education and rural infrastructure, and accelerating agricultural growth. This paper uses a computable general equilibrium (CGE) model to assess the potential impact on inequality and poverty of the key PRSP policies, as well as the effects of foreign debt forgiveness and changes in the copper sector. The findings suggest that, in the absence of very rapid growth, the pro-poor policies outlined in the PRSP will not enable Zambia to reach its Millennium Development Goal (MDG) of halving poverty by 2015. Achieving this goal will require gross domestic product (GDP) to grow at an annual rate of over ten percent. Reduction in poverty can however be achieved by addressing HIV/AIDS, which currently reduces annual GDP growth by one percent. Furthermore, substantial poverty-reduction can occur through the acceleration of agricultural growth, although limited market opportunities necessitates supporting investment in rural infrastructure. Overall, the potential of the agricultural sector depends on the government's commitment to reforms and the continued removal of the anti-agricultural bias created by the dominant copper sector.
Histories of forgetting, geographies of remembering : exploring processes of witnessing and performing in senior secondary humanities classroom(s)
Creators: name: England, Jacyntha
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the roles oral histories and drama can play in questioning and transforming dominant curricular narratives in senior secondary Humanities (Social Studies, First Nations Studies, History, Geography) education. The project centered on two classes (Social Studies 11, First Nations Studies 12) in a secondary school in Langley, British Columbia. In collaboration with the regular classroom teacher, the author designed two eight week study units, one for each course, that incorporated oral testimonies from Canadian marginalized communities into a pedagogical framework of critical analysis and reflective drama processes. The testimonies detailed such experiences as legislated segregation in the City of Vancouver, residential schooling and the Japanese internment. The author used the Theatre of the Oppressed techniques of Augusto Boal (image theatre, cops in the head, forum theatre) to facilitate the students in their responses to the testimonies. Students also participated in class discussions and completed written reflections at the end of each lesson and unit. This project created a curricular opening in which students could critically and creatively engage in personal and collective interrogations of "race", racism, colonialism, nation building and memory in both a historical and contemporary national context. For many of the students the material covered in the testimonies was new and disturbing, and the drama processes proved invaluable in allowing them to express their questions, reactions and understandings openly and without judgment. Many students developed new insights on themselves as members of a "multicultural" nation, and found strategies to help them question dominant curricular and national narratives. The responses from both the students and the cooperating teacher show overwhelmingly that this teaching approach was both useful to them in their development and should be expanded to other schools, subject areas and grade levels. However, serious systemic and structural obstacles, such as outcomes-based school and curricular expectations, unequal social relations in both schools and society, and teachers' lack of confidence in working with controversial issues need to be examined and overcome to bring this work to full fruition. This thesis uses various narrative styles - academic, autobiography, poetry and travelogue - to witness the project's themes and findings.

description: Inspection robots equipped with TV camera technology are commonly used to detect defects in sewer systems. Currently, these defects are predominantly identified by human assessors, a process that is not only time-consuming and costly but also susceptible to errors. Furthermore, existing systems primarily offer only information from 2D imaging for damage assessment, limiting the accurate identification of certain types of damage due to the absence of 3D information. Thus, the necessary solid quantification and characterisation of damage, which is needed to evaluate remediation measures and the associated costs, is limited from the sensory side. In this paper, we introduce an innovative system designed for acquiring multimodal image data using a camera measuring head capable of capturing both color and 3D images with high accuracy and temporal availability based on the single-shot principle. This sensor head, affixed to a carriage, continuously captures the sewer's inner wall during transit. The collected data serves as the basis for an AI-based automatic analysis of pipe damages as part of the further assessment and monitoring of sewers. Moreover, this paper is focused on the fundamental considerations about the design of the multimodal measuring head and elaborates on some application-specific implementation details. These include data pre-processing, 3D reconstruction, registration of texture and depth images, as well as 2D-3D registration and 3D image fusion.

description: Unlike its minimal counterpart, the Next to Minimal supersymmetric Standard Model (NMSSM) allows the possibility that the lightest neutralino could have a mass as small as $\sim 1 {\rm GeV}$ while still providing a significant component of relic dark matter (DM). Such a neutralino can provide an invisible decay mode to the Higgs as well. Further, the observed SM-like Higgs boson ($H_{125}$) could also have an invisible branching fraction as high as $\sim 19\%$. Led by these facts, we first delineate the region of parameter space of the NMSSM with a light neutralino ($M_{{\tildeχ}_{1}^{0}} < 62.5 {\rm GeV}$) that yields a thermal neutralino relic density smaller than the measured relic density of cold dark matter, and is also compatible with constraints from collider searches, searches for dark matter, and from flavor physics. We then examine the prospects for probing the NMSSM with a light neutralino via direct DM detection searches, via invisible Higgs boson width experiments at future $e^+e^-$ colliders, via searches for a light singlet Higgs boson in $2b2μ$, $2b2τ$ and $2\mu2τ$ channels and via pair production of winos or doublet higgsinos at the high luminosity LHC and its proposed energy upgrade. For this last-mentioned electroweakino search, we perform a detailed analysis to map out the projected reach in the $3l+{\rm E{\!\!\!/}_T}$ channel, assuming that chargino decays to $W {\tildeχ}_{1}^{0}$ and the neutralino(s) decay to $Z$ or $H_{125}$ + ${\tildeχ}_{1}^{0}$. We find that the HL-LHC can discover SUSY in just part of the parameter space in each of these channels, which together can probe almost the entire parameter space. The HE-LHC probes essentially the entire region with higgsinos (winos) lighter than 1 TeV (2 TeV) independently of how the neutralinos decay, and leads to significantly larger signal rates.

Relationships, status, and traditions : school and community in a Fijian village
Creators: name: Hoar, Marilyn Leone
Publisher: name: University of British Columbia

description: This two year ethnographic study was conducted in Fiji in a traditional hierarchical community with a largely subsistence economy. I set out to study the complex relations that exist between a school and its community, and specifically to determine (a) the factors that motivate or inhibit community members in their support of the local school and (b) how the various interests of parents, educators, community members, and international agencies are communicated and negotiated. Many existing studies of the connections between schools and communities in developing countries pay too little attention to the community's interests. In this study I drew on existing theories of community participation in education to develop a broad-based, multi-faceted framework that guided data collection. My data demonstrate that in traditional, hierarchical societies, families' decisions about supporting formal education for one individual are made within a communal framework that also values activities that strengthen relationships, enhance status, and preserve traditions. Families preferred academic education in English over vocational training because of the increased status these programs provided to the student. While there was little support for programs to maintain local culture and language, the community did not support schooling that eroded the traditions of the community. These factors help to account for the presence of both support and resistance towards programs of economic and social development. This study found that Western models of parental participation or community involvement for the purposes of improving student achievement, increasing community funding, or enhancing the accountability of education systems do not necessarily apply to other cultures. Educators must understand the patterns of relationships, status, and traditions that exist within a community in order to successfully communicate educational goals and negotiate the interests of all groups. Relationships, status, and traditions within which school-community relations exist in developing countries are complex, dynamic, and powerful. For educators at the local, national, and international levels to succeed, they must develop strategies for identifying, comprehending, and working within these often powerful forces.
Constraints on the Size of the Smallest Triggering Earthquake from the ETAS Model, Baath's Law, and Observed Aftershock Sequences

description: The physics of earthquake triggering together with simple assumptions of self-similarity impose the existence of a minimum magnitude m0 below which earthquakes do not trigger other earthquakes. Noting that the magnitude md of completeness of seismic catalogs has no reason to be the same as the magnitude m0 of the smallest triggering earthquake, we use quantitative fits and maximum likelihood inversions of observed aftershock sequences as well as Baath's law, compare with ETAS model predictions and thereby constrain the value of m0. We show that the branching ratio $n$ (average number of triggered earthquake per earthquake also equal to the fraction of aftershocks in seismic catalogs) is the key parameter controlling the minimum triggering magnitude m0. Conversely, physical upper bounds for m0 derived from state- and velocity-weakening friction indicate that at least 60 to 70 percent of all earthquakes are aftershocks.

description: In this paper we consider an extension of the linear exponential distribution based on the Harris generalization method, which includes some of the life time distribution as sub models. Along with the four parameter generalization namely Harris generalized linear exponential distribution, we derive some of its properties such as moments, quantiles and moment generating function. A compound form expression of the density function is given. For the given model the R´enyi entropy, mean residual life and the distribution of order statistics is derived. The problem of estimation of parameters is considered and validated with respect to two real data sets.

description: In this work, a method for automatic analysis of natural aggregates using hyperspectral imaging and high-resolution RGB imaging combined with AI algorithms consisting of an intelligent deep-learning-based recognition routine in form of hybrid cascaded recognition routine, and a necessary demonstration setup are demonstrated. Mineral aggregates are an essential raw material for the production of concrete. Petrographic analysis represents an elementary quality assurance measure for the production of high-quality concrete. Petrography is still a manual examination by specially trained experts, and the difficulty of the task lies in a large intra-class variability combined with low inter-class variability. In order to be able to increase the recognition performance, innovative new classification approaches have to be developed. As a solution, this paper presents an innovative cascaded deep-learning-based classification and uses a deep-learning-based data augmentation method to synthetically generate images to optimize the results.

description: Stereo imaging provides an easy and cost-effective method to measure 3D surfaces, especially due to the availability of extensive free program libraries like OpenCV. An extension of the application to the field of forestry was aimed at here in the context of a project to capture the elevation profile of forest roads by means of stereo imaging. For this purpose, an analysis of the methods contained in OpenCV for the successful generation of depth maps was carried out. The program sections comprised the reading of the image stream, the image correction on the basis of calibrations carried out in advance as well as the generation of the disparity maps by the stereo matchers. These are then converted back into depth maps and stored in suitable memory formats. A data set of the image size 1280x864 pixels consisting of 30 stereo image pairs was used. The aim was to design an evaluation program which allows the processing of the described steps within one second for 30 image pairs. With a sequential processing of all steps under the used test system and the usage of a local stereo matcher a processing time of 4.37 s was determined. Steps to reduce the processing time included parallelizing the image preparation of the two frames of the image pair. Further reduction in total processing time was achieved by processing multiple image pairs simultaneously and using storage formats without compression. A total processing time of 0.8 s could be achieved by outsourcing the stereo matching to the graphics card. However, the tested method did not achieve the desired resolutions in depth as well as in the image plane. This was made possible by using semi-global matchers, which are up to 10 times slower but significantly more accurate, and which were therefore used for further investigations of the forest path profile.

description: A key objective of China's reform program was to reduce distortions in the economic system and enhance growth. However, when implemented in incremental and partial ways, local governments or individuals have chance to capture rents inherent in the reform process. Young (2000) warned that the rent-seeking behavior might lead to increasing market fragmentation. Empirical studies have since shown that this did not happen in the product markets. In this paper we argue that as rents from the product markets were squeezed out during the reform process, rent-seeking behavior shifted to the factor markets, especially the capital and land markets. The reform process now needs to be deepened to ensure that the factor markets also become more integrated and efficient.
