Abstract:

A physically based model describing the mechanism of surface sealing of soil was evaluated in the context of aggregate stability. The intent of the model study was to better understand the effect of mixing fine-textured mineral subsoil with organic surface soil on structural stability and surface seal formation. The mixing results from tillage and harvesting operations, and management practices such as levelling. The index derived from the model showed that sealing of the shallow organic soil increased with an increase of mineral matter content. The mathematical formulation of the model was based on the principle of conservation of mass and Darcy's law for flow of water through a layered soil column. Assuming convective flow, it was shown theoretically that the rate of surface seal formation is proportional to the flux density of the filtrate, as assumed by Scheidegger (1974). In the model it was further assumed that the pore necks at the soil surface clog first before the seal develops. The assumption that convective flow alone was responsible for the movement of the suspension is likely incorrect for suspensions derived from medium or coarse textured soils, since sedimentation does influence the movement of larger particles. However, introducing a constant sedimentation parameter into the convective flow model did not improve the model. Therefore, it is likely a non-constant sedimentation parameter could improve the model considerably. The model showed that for sufficiently large times the flux density of a filtrate flowing through a soil column at a constant hydraulic head is proportional to inverse square root of time. Testing the model experimentally showed a good agreement between theory and experiment. A highly significant correlation between the soil stability factor derived from the model and aggregate stability suggests that the index is a soil structural attribute. The soil stability factor was exponentially related with aggregate stability and mineral matter content. However, whereas the relationship between the soil stability factor and aggregate stability gave a positive exponent, a negative exponent was obtained with mineral matter content. Further studies showed that structural stability and saturated hydraulic conductivity of the aggregate beds were positively and significantly correlated exponentially. However, saturated hydraulic conductivity and mineral matter content were negatively and significantly correlated exponentially. Collateral to the results of the model, the strong negative correlation between wet-sieved aggregate stability and mineral matter content confirmed the deleterious effect of mixing fine-textured mineral soil on the structure of the shallow organic soil. It was theorized that aggregates stabilized through clay-organic complexing are likely to be much stronger than aggregates stabilized through other mechanisms. This implies that whenever the mineral matter content is much higher than the organic matter content, the surplus mineral matter that does not interact with organic matter will be most dispersible. The high silt content of the mineral matter fraction is likely to be an important factor contributing to the decrease in structural stability with increasing mineral matter content. Once the clay and the organic colloids have interacted, the silt that remains is not capable of forming stable aggregates without colloids (Baver et al. 1972). From measurements of the air to water permeability ratio, the decrease in saturated hydraulic conductivity of the aggregate beds with increasing mineral matter content was attributed to slaking of the mineral matter fraction. However, it is possible for the soil with high mineral matter content to be stable if the mineral matter is allowed to be in contact with the organic matter for a long period of time.

Abstract:

Adjacent terrestrial habitat surrounding wetlands are critical for the survival and success of many species that use them. The primary purpose of this study was to determine amphibian movement from adjacent habitats into Orchard Bog, a restored bog located in Shady Valley, Johnson County, Tennessee. In addition, a secondary bog, Quarry Bog, was also studied determining baseline presence/absence data A total of 16 species from six families were observed throughout the study sites. Seven species of anurans, Bufonidae, Hylidae, and Ranidae and nine species of caudates in the families Plethodontidae, Ambystomatidae and Salamandridae were identified. Fourteen of the 16 species were found within Orchard Bog. Data collected can be used to help determine more beneficial land acquisitions and management strategies. Survey methods included pitfall traps, funnel traps, coverboard arrays, and opportunistic surveys.

AN ABSTRACT OF THE THESIS OF SHIBAJI CHATTERJEE, for the Master of Science degree in Geology, presented on APRIL 23, 2009, at Southern Illinois University Carbondale. TITLE: GEOPHYSICAL STUDIES OF THE HERALD-PHILLIPSTOWN FAULT AND OTHER SHALLOW STRUCTURES NEAR CARMI, ILLINOIS. MAJOR PROFESSOR: Dr John L. Sexton Four seismic reflection profiles from the Wabash Valley area of southeastern Illinois successfully imaged the Herald-Phillipstown fault. From the reflection profiles and geophysical well logs, it was interpreted that the Herald-Phillipstown fault is an inverted flower structure. The main fault of the group is a steeply dipping normal fault with associated splay faults that are reverse in character. All the faults of this inverted flower structure are basement penetrating. Structural contour maps as well as maps of various reflector surfaces are prepared using two way travel time as well as depth. These maps show that the reflectors are undulating in character. Also distinct east-west rotational movements of the reflectors are observed along these faults and the main fault shows a curved geometry from south to north. The combination of the rotational movement, the curved nature of the fault plane and the undulating reflectors resulted in variation of offsets along these faults. The nature of faults of the inverted flower structure as observed on the seismic reflection profiles also indicates that there has been a change in the stress regime from extensional to compressional. Structural cross sections were generated using geophysical well logs from drill holes located along these seismic lines to analyze the nature of these faults at shallower depths. From these cross sections numerous shallow faults were observed and many of them can be correlated with those observed on seismic records indicating upward migration of basement penetrating faults into shallow younger sediments. Many of these faults, including the Herald-Phillipstown fault show evidences of reactivation.

Full text

Abstract:

The late Quaternary stratigraphy of three Paleoindian archaeological sites, located on the edge of Shaw Creek Flats in the middle Tanana Valley, Alaska, consist of up to 2 meters of calcareous eolian sand, loess, and buried paleosols. Two Paleoindian occupations at the Broken Mammoth, Swan Point, and Mead sites date from 11,800 to 11,000 yr B.P. and from 10,800 to 9500 yr B.P. Well-preserved faunal remains, worked mammoth ivory, stone and organic tools, and at Swan Point, the early occurrence of microblades dating to 11,700 yr B.P., are associated with buried paleosols at the base of the loess. Stratigraphic and radiocarbon-chronological correlations between the sites, and at similar geological sections, suggest the presence of a regionally-correlative, eolian stratigraphy consisting of three main units: (1) a basal gray eolian sand, overlying a deflated, ventifacted, bedrock surface, was deposited as bluff-top sand sheets probably during the Birch Period transition from periglacial steppe-tundra environments to shrub tundra about 12,000 to 14,000 yr B.P. (2) An overlying lower loess unit contains three paleosol complexes, classified as Typic Cryorthents, which consist of a series of cumulative Abk horizons overlying Ck loess parent material. The lower paleosol complex dates to 11,800 to 11,000 yr B.P. as is associated with the initial occupation of the sites. The middle paleosol complex dates from 10,800 to about 9500 yr B.P. and is associated with the second Paleoindian occupation. The upper paleosol complex is weakly developed, contains no cultural material, and reflects an increase in loess deposition rates. Abundant pedogenic carbonate features indicate dry, warm, alkaline soil conditions. Faunal remains, soil characteristics, and regional palynological studies indicate a warm, dry, open parkland of poplar-willow scrub forest during the deposition of the lower loess, paleosol formation, and Paleoindian occupations. (3) An upper loess unit, up to a meter thick, lacks paleosols, has been leached of carbonate, and has a late Holocene Alfic Cryochrept soil developed on its upper surface. Rapid, coarse-grained loess deposition occurred from about 9000 to 6000 yr B.P. By 4500 yr B.P., slow, fine-grained loess deposition began under boreal forest conditions and continues today.

Abstract:

Throughout the alpine domain, shallow landslides represent a serious geologic hazard, often causing severe damages to infrastructures, private properties, natural resources and in the most catastrophic events, threatening human lives. Landslides are a major factor of landscape evolution in mountainous and hilly regions and represent a critical issue for mountainous land management, since they cause loss of pastoral lands. In several alpine contexts, shallow landsliding distribution is strictly connected to the presence and condition of vegetation on the slopes. With the aid of high-resolution satellite images, it's possible to divide automatically the mountainous territory in land cover classes, which contribute with different magnitude to the stability of the slopes. The aim of this research is to combine EO (Earth Observation) land cover maps with ground-based measurements of the land cover properties. In order to achieve this goal, a new procedure has been developed to automatically detect grass mantle degradation patterns from satellite images. Moreover, innovative surveying techniques and instruments are tested to measure in situ the shear strength of grass mantle and the geomechanical and geotechnical properties of these alpine soils. Shallow landsliding distribution is assessed with the aid of physically based models, which use the EO-based map to distribute the resistance parameters across the landscape.
In tutto l'arco alpino, le frane superficiali rappresentano un rischio estremamente attuale che ogni anno causa ingenti danni alle infrastrutture, alle proprietà e, nei casi più tragici, provocano perdite umane. Le frane superficiali rappresentano un importante fattore di evoluzione del paesaggio alpino in quanto provocano perdita di suolo e modificano quindi la distribuzione dei terreni adibiti al pascolo. L'analisi dei meccanismi di innesco delle frane superficiali e la loro distribuzione, deve essere condotta partendo da una profonda conoscenza dei parametri geomeccanici che caratterizzano il suolo e soprassuolo. Nell'area di studio, un bacino montano situato tra i 1900 e i 2400 m s.l.m., la maggior parte dei versanti è ricoperta da un fitto manto erboso, il Nardetum; questa copertura vegetale tuttavia, presenta degli evidenti pattern di degradazione, causati dall'intesa attività pastorizia. Nelle zone in cui il manto erboso è danneggiato, le resistenze calano drasticamente, aumentando quindi la vulnerabilità al franamento superficiale. L'obiettivo di questo lavoro è quello di combinare la suddivisione del territorio, fatta attraverso tecniche di classificazione automatica delle immagini satellitari alle proprietà geomeccaniche e geotecniche delle diverse coperture. La caratterizzazione di queste proprietà del suolo e soprassuolo è stata condotta utilizzando sia strumenti e metodi tradizionali, sia tecniche innovative e strumenti sperimentali. Infine per studiare la distribuzione delle frane superficiali, i dati raccolti in campagna e suddivisi nelle diverse classi di copertura, sono stati inseriti in modelli di stabilità dei versanti.

Abstract:

Shadow removal is an important problem for both artists and algorithms. Previous methods handle some shadows well but, because they rely on the shadowed data, perform poorly in cases with severe degradation. Image-completion algorithms can completely replace severely degraded shadowed regions, and perform well with smaller-scale textures, but often fail to reproduce larger-scale macrostructure that may still be visible in the shadowed region. This paper provides a general framework that leverages degraded (e.g., shadowed) data to guide the image completion process by extending the objective function commonly used in current state-of-the-art image completion energy-minimization methods. This approach achieves realistic shadow removal even in cases of severe degradation and could be extended to other types of localized degradation.

Abstract:

Skuggor är centrala för hur människan uppfattar världen. Inom datorspel och andra interaktiva 3D-applikationer är det viktigt att underlätta förståelsen av scenen och det finns även ofta en stark vilja att skapa realistiska miljöer. Detta samt att skuggsättning är en komplicerad och prestandakrävande operation gör det till ett viktigt område inom realtidsgrafik. Vi undersöker i denna avhandling relationen mellan prestandan (renderingstiden) för de två populära metoderna för skuggsättning inom realtidsgrafik, shadow mapping och shadow volumes. Undersökningen avgränsas till två utvalda varianter av de ursprungliga algoritmerna. I och med lanseringen av den nya versionen av Direct3D, version 10, öppnas möjligheten för optimeringar av algoritmerna genom användandet av framförallt geometry shaders. På grund av detta implementerar vi algoritmerna både med och utan den nya funktionalitet som introduceras i Direct3D 10 för att besvara om det är möjligt att förbättra prestandan för algoritmerna i Direct3D 10. Resultatet visar tydligt shadow mapping-algoritmens överlägsenhet för annat än scener med mycket få polygoner. Variabler så som ljusets infallsvinkel och objekts storlek har liten inverkan på det slutgiltiga resultatet för när vilken algoritm har bättre prestanda. Resultatet visar även tydligt att användandet av geometry shaders ger en mycket kraftig försämring av prestandan för båda algoritmerna.
Inom interaktiv 3D-grafik som exempelvis datorspel är det viktigt att skapa realistiska miljöer. Att rita ut en realistisk 3D-värld såpass snabbt att användaren inte kan se enskilda bildrutor kräver mycket kraft av datorn. Det är därför viktigt att datorprogrammet använder snabba och effektiva algoritmer. Skuggor är viktigt för att skapa realistiska 3D-miljöer. Detta arbete jämför snabbheten och effektiviteten mellan två olika metoder för att bestämma vad i 3D-världen som ligger i skugga.

Abstract:

The purpose of this project was to explore the nature of relationships and the concept of light and dark aspects of personality in a fantasy setting.Sisters of Shadow is the story of telepathically linked twin sisters who study in rival schools of magic. When their unique bond is discovered, they must deal with the hostile emotions it inspires in others. The pivotal event in the story is a test both girls must undergo before they can become apprentices in their respective schools of magic. The test forces them to work together, light magic balancing and harmonizing with dark magic. An assassination attempt also serves to bring the sisters together, body, mind and spirit; this results in a closer examination of the telepathic link and its potential uses, and the ethical issues its use raises.The story, intended as the first book, or section, of a larger work is targeted at young adults. It deals with young characters and their struggles to reach maturity. Its primary theme, that light and dark forces, the power to do good and the power to do evil, reside within every one of us, is somewhat allegorical in nature. As the work progresses, the idea that there can be a balance between the two forces in shadow--the mixture of light and dark--will be developed. In this story, however, the sisters have their first encounter with shadow and it is a terrifying one. It is the first in a series of experiences that will lead them to discover that the shadow realm is a meeting place where both girls can use their skills to their fullest.It should also be noted that this story uses a convention specific only to the fantasy genre. To differentiate mindspeech from regular conversation, colons are used in place of quotation marks and dialogue is italicized.

This paper describes an interactive computer program that can be used as a design tool in assessing the shading effects of trees in relation to buildings. The program determines the area and position of the shadow cast by a tree or group of trees on a surface of a building which can have any orientation. The program outputs numerical and · graphical hourly results at any time of the day, for any day of the year, at any location on the earth, for any relative positioning between the tree and building, and estimates percent irradiation reductions on building surfaces resulting from tree shade. The program allows three different shapes of tree (elliptical, cylindrical, and parabolic) to be used. This program is being interfaced with a commercially available building energy analysis program.

Abstract:

The best kind of poem, I think, is that which delights readers by drawing them toward another world, whether that world is located closer to the real or closer to the fantastic. Perhaps delight at being drawn toward another world is the criterion of excellence for all creative work, not specifically poems. Nevertheless, this criterion has become, through my writing of the present poems, my guiding principle as a poet. My poems, if they succeed, are windows to other worlds. Because these worlds are not, and cannot be, wholly developed in individual poems, readers see in each poem only a part of a vastly larger realm and what is not seen is unknown, a mystery. Here, the ordinary is decontextualized and strange, and the bizarre, too, is decontextualized and has a weight like that of the ordinary. The field of possibility is leveled; anything could happen. This is frightening. Looking through the windows of the poems, the reader may predict that terrible things are about to happen in these other worlds, but they are helpless to intervene. Fascination is perhaps the only option. I would be pleased to have my readers say that they felt compelled by my poems and that their being compelled left them wondering what caused people, in reading, not only to imagine things that did not exist but to care about them.

Full text

Abstract:

This study provides a comparative analysis, using dialectical hermeneutics, of the philosophy of Plotinus and the depth psychology of C. G. Jung. While coming from different historical contexts, they each address the nature of unconsciousness, or the unconscious. This study concentrates in particular on one archetypal aspect of the unconscious that Jung calls the shadow. According to Jung, the shadow is a psychological dynamic that both hides from our awareness certain aspects or depths of our own inner reality, and also, when recognized, mediates our initial confrontation with those fuller realities. The first aim of this study is to analyze Jung’s view of the psyche, through the lens of shadow, to reveal the shadow in Jung’s work, examining how he denies or disavows metaphysical reality as a legitimate domain of depth psychological inquiry. Secondly, the biographical and historical backgrounds to this shadow are explored, and the potential consequences of it are discussed. Finally, Plotinus’ ancient perspective on unconsciousness and what he understands as the metaphysics of shadow are brought into dialogue with Jung. The goal is to address the shadow in Jung’s work—what his view of depth psychology denies to depth psychology, offering another way of understanding the psyche, and the shadow in particular, that includes metaphysical reality as a legitimate domain of depth psychological experience and analysis.

Abstract:

In this study 19 tunnel valleys within block 2/4 in the central North Sea basin have been mapped. Furthermore, the possibility for these valleys to act as migration paths for leaked gas has been evaluated. In January 1989 a kick occurred while drilling well 2/4-14 in the area of study, hence the pertinence of evaluating this hypothesis at this locality is evident. The work has been performed using multichannel 2D lines and a conventional 3D seismic survey. The quality of the 2D and 3D data is clearly dissimilar at shallow burial depths, as the 2D data is considered to be high-resolution while the 3D data is low-resolution. However, both data sets have proved to give valuable information on the valley morphology. Great details about the extent and basal morphology have been retrieved from the conventional 3D volume; whereas seismic characteristics of the valley infill have been interpreted from the 2D lines. Tunnel valleys are major, elongated incisions carved into sediments or permeable bedrock during glaciations. They tend to be sinuous in planform, but might also appear as straight valleys. Tunnel valleys often consist of several cut- and fill-structures, both laterally and vertically, and thus form a network of interconnected valleys. This has also been observed in the area of study. No sedimentological logs have been available in the study. Hence, the interpretations of valley fill lithologies are based on the seismic characteristics, and thereby they are quite cautious. The typical fill sequence observed correlates fairly good with similar valleys mapped in the area previously. A lower part of chaotic reflectors, believed to be glaciofluvial sands and gravels, is overlain by sub-horizontal layers of glaciomarine mud. Moreover, velocity pull-up effects are seen in the underburden of some of the valleys. These indicate relatively high velocities of the infill sediments, and hence, it is likely to be clayey tills. Even so, the possibility of gas migration within the tunnel valley system is believed to be conspicuous.

Shen, Yang. "Soft Shadow Mip-Maps." Thesis, The University of Utah, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10158459.

Full text

Abstract:

This document introduces the Soft Shadow Mip-Maps technique, which consists of three methods for overcoming the fundamental limitations of filtering-oriented soft shadows. Filtering-oriented soft shadowing techniques filter shadow maps with varying filter sizes determined by desired penumbra widths. Different varieties of this approach have been commonly applied in interactive and real-time applications. Nonetheless, they share some fundamental limitations. First, soft shadow filter size is not always guaranteed to be the correct size for producing the right penumbra width based on the light source size. Second, filtering with large kernels for soft shadows requires a large number of samples, thereby increasing the cost of filtering. Stochastic approximations for filtering introduce noise and prefiltering leads to inaccuracies. Finally, calculating shadows based on a single blocker estimation can produce significantly inaccurate penumbra widths when the shadow penumbras of different blockers overlap.

We discuss three methods to overcome these limitations. First, we introduce a method for computing the soft shadow filter size for a receiver with a blocker distance. Then, we present a filtering scheme based on shadow mip-maps. Mipmap-based filtering uses shadow mip-maps to efficiently generate soft shadows using a constant size filter kernel for each layer, and linear interpolation between layers. Finally, we introduce an improved blocker estimation approach. With the improved blocker estimating, we explore the shadow contribution of every blocker by calculating the light occluded by potential blockers. Hence, the calculated penumbra areas correspond to the blockers correctly. Finally, we discuss how to select filter kernels for filtering.

These approaches successively solve issues regarding shadow penumbra width calculation apparent in prior techniques. Our result shows that we can produce correct penumbra widths, as evident in our comparisons to ray-traced soft shadows. Nonetheless, the Soft Shadow Mip-Maps technique suffers from light bleeding issues. This is because our method only calculates shadows using the geometry that is available in the shadow depth map. Therefore, the occluded geometry is not taken into consideration, which leads to light bleeding. Another limitation of our method is that using lower resolution shadow mip-map layers limits the resolution of the shadow placement. As a result, when a blocker moves slowly, its shadow follows it with discrete steps, the size of which is determined by the corresponding mip-map layer resolution.

Transition is the movement between the past and the future. In architecture, transition is both temporal and spatial. It is the interstitial space where changes happen. A thoughtful architectural transition prepares for journey ahead by intensifying aspects of space and relating it to the before and after. In the analogous the trifold structure of time and tenses, transition could be designated as the present, situate between past and future. Transition is always assumed as a space that connects the two other spaces. The thesis claims that a building functions better with a thoughtful transition. It is based on an assumption that a well-considered transition is an architectural offering to better comprehend change.

Abstract:

The Genetic Algorithm (GA) is a popular global search algorithm. Although it has been used successfully in many fields, there are still performance challenges that prevent GA’s further success. The performance challenges include: difficult to reach optimal solutions for complex problems and take a very long time to solve difficult problems. This dissertation is to research new ways to improve GA’s performance on solution quality and convergence speed. The main focus is to present the concept of shadow price and propose a two-measurement GA. The new algorithm uses the fitness value to measure solutions and shadow price to evaluate components. New shadow price Guided operators are used to achieve good measurable evolutions. Simulation results have shown that the new shadow price Guided genetic algorithm (SGA) is effective in terms of performance and efficient in terms of speed.

Abstract:

Geosynchronous (GEO) satellites are essential for modern communication networks. If communication to a GEO satellite is lost and a malfunction occurs upon orbit insertion such as a solar panel not deploying there is no direct way to observe it from Earth. Due to the GEO orbit distance of ~36,000 km from Earth's surface, the Rayleigh criteria dictates that a 14 m telescope is required to conventionally image a satellite with spatial resolution down to 1 m using visible light. Furthermore, a telescope larger than 30 m is required under ideal conditions to obtain spatial resolution down to 0.4 m. This dissertation evaluates a method for obtaining high spatial resolution images of GEO satellites from an Earth based system by measuring the irradiance distribution on the ground resulting from the occultation of the satellite passing in front of a star. The representative size of a GEO satellite combined with the orbital distance results in the ground shadow being consistent with a Fresnel diffraction pattern when observed at visible wavelengths. A measurement of the ground shadow irradiance is used as an amplitude constraint in a Gerchberg-Saxton phase retrieval algorithm that produces a reconstruction of the satellite's 2D transmission function which is analogous to a reverse contrast image of the satellite. The advantage of shadow imaging is that a terrestrial based redundant set of linearly distributed inexpensive small telescopes, each coupled to high speed detectors, is a more effective resolved imaging system for GEO satellites than a very large telescope under ideal conditions. Modeling and simulation efforts indicate sub-meter spatial resolution can be readily achieved using collection apertures of less than 1 meter in diameter. A mathematical basis is established for the treatment of the physical phenomena involved in the shadow imaging process. This includes the source star brightness and angular extent, and the diffraction of starlight from the satellite. Atmospheric effects including signal attenuation, refraction/dispersion, and turbulence are also applied to the model. The light collection and physical measurement process using highly sensitive geiger-mode avalanche photo-diode (GM-APD) detectors is described in detail. A simulation of the end-to-end shadow imaging process is constructed and then utilized to quantify the spatial resolution limits based on source star, environmental, observational, collection, measurement, and image reconstruction parameters.

Abstract:

If C is a convex body in R^n and X is a k-dimensional linear subspace of R^n, we denote by S(C,X) the shadow boundary of C over X which is deﬁned as the collection of all points which belong to C and to one of its tangent (n-k)-ﬂats orthogonal to X. For almost all directions in R^3, the shadow boundary is a curve encompassing the body C. It has been established long ago by G. Ewald, D.G. Larman and C.A. Rogers [11] that, for every given C, S(C,X) is almost always a topological (k-1)-sphere. As a follow on from this result, in 1974 Peter McMullen asked whether most of these shadow boundaries would have ﬁnite “length” [15]. This is already shown to be true for polytopes and also true for general convex bodies when the dimension of the subspace X is 1 or n-1. Here we show that almost all shadow boundaries have ﬁnite “length” whatever the dimension k, 0< k< n, of the subspace X. The set of shadow boundaries of inﬁnite “length” has also been considered in the context of Baire category. In 1989, P. Gruber and H. Sorger proved that, in the Baire category sense, most pairs (C,X), where C is a convex body in R^n and X an (n-1)-dimensional subspace of R^n, produce shadow boundaries S(C,X) of inﬁnite length. Here we show that this result also holds for pairs (C,X) where X is a k-dimensional subspace, 0< k< n. We also consider the length of increasing paths in the 1-skeleton of a convex body. We conclude with observations and open questions arising from the work on shadow boundaries of the ﬁrst two chapters.

Abstract:

The Shadow Line is a collection of six short stories featuring characters whose lives take them near, and often across, the metaphorical Line that separates light from dark. Some of these characters indeed straddle that Line, living lives of apparent uprightness while harboring the seeds of inescapable menace. Some hover on the outside of some social structure and yearn to cross over, to leave the shadows of their lives outside for the apparent radiance within. And some live in worlds of brightness and comfort, only to find themselves confronting sudden moments of inexplicable terror. Told from various points of view, these stories invite the reader to listen to the characters — to explore the secrets they keep, the fears and doubts and dangers they face as they confront the darkness — and to inhabit with them, for a short time, the menacing world on either side of the Shadow Line.

Abstract:

"Muitos, como dizia Artaud, referindo-se aos críticos, "gostariam que a nossa aprendizagem fosse feita entre quarto paredes, fechada no laboratórios", mas nos fazemos cena aberta, cara a cara com o publico. "Many", as Artsud used to say, referring to the critics, "would like our learning to take place within four walls, enclosed in laboratories", but we rather do it openly, face to face with the public" (Itaqui, 2005). "Fields are greener in their description than in their actual greenness. Flowers, if described with phrases that define them in the air of the imagination, will have colours with a durability not found in cellular life" (Zenith, 2001). This thesis proposes Critical Portfolio as a new format for methodological exchange between curators of contemporary visual arts. The research took place between the years of 2001 and 2006 and was based on the curotion of exhibitions with strong visible idiosyncratic approaches to selection and display (these becoming the research questions). It wasfollowed by the documentation and critical reflection of their associated methodologiesand final outputs, and resulted in a Critical Portfolio with clear links threaded between thevarious sections. The research is an enquiry into the nature of process and impacts upon themethodological visibility of emerging fields of curatorial practice and research.This charting of curatorial activity is divided in two parts:Projects included (with relation to the research questions) and projects excluded (with no clear relation to the research questions). Part 1- The projects included (4th year Expo, B-Sides - The Sculpure Show, Art Cup and A-Tipis) have token place in various European institutions and propose specific approaches to selection and display.Part 2- Projects excluded (Ver?o, Her?is e ViI es, Gran Pacman etc) do not show a clear relation to methods of selection and display. Each individual project in Part 1 is organized according to a common structure consisting of Project Image, Exhibition Pro-Forma, Concept Development, Portfolio Images,Correspondence between Curator and Artists, and Process Documentation. This structure, which takes a different configuration in each of the projects, allows for a clear and objective search for specific elements and contributes to new possibilities for comparison. The relation between the projects and the curatorial methods of selection and displaydenote critical preoccupations which become synthesized in the Curatorial Programms. This thesis identifies a "gap" in the structure of curatorial handbooks and proposes an approach that will not only close it, but bring more depth to an arising discussion around curatorial methodologies. Imagining this Critical Portfolio turns into a chapter of a curatorial handbook (synthesis of a curator's practice), the handbook is thus turned into a library/archive hosting each individual curator's documented methodology (Capital Culturalas repository of multiple curatorial practices is described in the Conclusion).

Sieber, Martina. "Shadow prices in Czech economy." Doctoral thesis, Vysoká škola ekonomická v Praze, 2006. http://www.nusl.cz/ntk/nusl-72789.

Full text

Abstract:

The doctorial thesis is focused on shadow pricing. The aim is to describe as complex and full description of the problem as possible. Briefly said, Shadow prices are prices of goods which would take a place on the efficient market, if such a market with the commodity existed. In the case of consumption benefits they in fact present monetary value of the utility increment resulted from additional consumption. They are basic information input into any socioeconomic evaluation. Research of shadow prices is underdeveloped in the Czech Republic. With respect to the fact the thesis contents description of basic theoretical concepts as well as list of attainable methods for shadow prices derivation. Main variables determining shadow prices (under condition of WTP, WTA and Social Opportunity Costs concepts) are the existed society welfare and social preferences. From this perspective if clear and evident that there would not be appropriate to use shadow prices conducted abroad for evaluation in the Czech economy. Each state has its own level of welfare as well as specific social and ethical values widespread among citizens and so specific shadow prices as well. Not just shadow prices them self are not simply applicable for evaluation in each country. Similar problem we have to face, if we try to use the same methods of deriving shadow prices in different areas. That is why the thesis also serves critical analysis of attainable methods and their assessment. Based on the assessment is stated, what methods are more or less appropriate and under which condition in the Czech area. In principal should shadow prices reflect Social Opportunity Costs of input usage for evaluated changes and Willingness to Pay of the society for the outputs of evaluated changes (or alternatively Willingness to Accept) with no respect to the fact if the good (or output or input) is market good or nonmarket good. Even though we differentiate in the methodological level between market and nonmarket good the theoretical and conceptual background is the same. The background is rooted in the neoclassical economics. For the practical reasons as a analyst time and budget constrain it is not too efficient in evaluation of marketed goods always perform deep empirical market analysis from primary data even though it would be theoretically ideal and correct. Fortunately we are usually not forced to do it. In majority of cases we can follow LMST methodology of shadow prices and derive so called Conversion Factors for transformation of market prices to shadow prices. The Conversion factors are usually derived for wider group of goods which is sold in the similar market. Such values we call Sector Conversion Factors. A Shadow price of an individual unique good we than receive by its market price multiplication by most appropriate sector conversion factor. With respect to current Czech evaluation practice situation, when sector conversion factor are very often used but their estimates are more less based on very poor quality of underlying theory and very often without sufficient data background, the quantification of SCF in the theses could be viewed as quite significant contribution. With respect to their specific characteristics nonmarket good as safety (VSL), time, noise, etc. should be valued separately. And the thesis is offering at least methodological contributive guidelines regarding theoretical validity and relevance as well as assessment of their applicability under Czech condition. For better imagination there is collected sample of results of selected externality values for foreign countries.

Abstract:

Computer vision applications are often confronted by the need to differentiate between objects and their shadows. A number of shadow detection algorithms have been proposed in literature, based on physical, geometrical, and other heuristic techniques. While most of these existing approaches are dependent on the scene environments and object types, the ones that are not, are classified as superior to others conceptually and in terms of accuracy. Despite these efforts, the design of a generic, accurate, simple, and efficient shadow detection algorithm still remains an open problem. In this thesis, based on a physically-derived hypothesis for shadow identification, novel, multi-domain shadow detection algorithms are proposed and tested in the spatial and transform domains. A novel "Affine Shadow Test Hypothesis" has been proposed, derived, and validated across multiple environments. Based on that, several new shadow detection algorithms have been proposed and modelled for short-duration video sequences, where a background frame is available as a reliable reference, and for long duration video sequences, where the use of a dedicated background frame is unreliable. Finally, additional algorithms have been proposed to detect shadows in still images, where the use of a separate background frame is not possible. In this approach, the author shows that the proposed algorithms are capable of detecting cast, and self shadows simultaneously. All proposed algorithms have been modelled, and tested to detect shadows in the spatial (pixel) and transform (frequency) domains and are compared against state-of-art approaches, using popular test and novel videos, covering a wide range of test conditions. It is shown that the proposed algorithms outperform most existing methods and effectively detect different types of shadows under various lighting and environmental conditions.

Abstract:

Skuggor i 3D-miljöer är ett mycket efterforskat område, och detta arbete koncentrerar sig på shadow map-algoritmen. Det finns ett problem med denna algoritm, för då en shadow map projiceras på en yta som är större än sig själv så bildas stora trappstegseffekter, vilket kallas aliasing. Problemet som har undersökts är hur olika shadow map-algoritmer i en miljö med långa skuggor beter sig, där ett minimerat antal artefakter så som brus och aliasing är synligt. För detta undersöktes Percentage-Closer Filtering (PCF), som är en variant av shadow map, med olika samplingstekniker – och även en vidarebyggnad med Percentage-Closer Soft Shadow (PCSS) implementerades. Mätningar av realism och brusmängd genomfördes med en användarstudie. Prestandan mättes i klockcykler. Resultatet visade att PCF med samplingstekniken Edge Tap Smoothing kan vara den algoritm som lämpar sig bäst i situationer med långa skuggor i en 3D-miljö; detta för att den interpolerar mellan de projicerade texlarna.
