New laboratory data are presented on the influence of long waves on sediment transport in the surf zone. Due to the very significant difficulties in isolating the morphodynamic processes induced by long waves in field conditions, the laboratory study was designed practically to measure the net sediment transport rates, and gradients in sediment transport, arising from the interaction between long waves and short waves in the surf zone. The bathymetric evolution of model sand beaches, with dB50B = 0.2 mm, was observed under monochromatic short waves, long-wave short-wave combinations (free long waves), and bichromatic wave groups (forced long waves). The beach profile change and net cross-shore transport rates, Q(x), were extracted and compared for conditions with and without long waves. The experiments include a range of wave conditions, e.g. high-energy, moderate-energy, low-energy waves, and the beaches evolve to form accretionary, erosive, and intermediate beach states. Hydrodynamic measurements were made to identify the influence of long waves on short waves and to determine the correlation between surf zone bars and standing long waves. A shallow water wave model was modified for this application to surf zone morphodynamics and compared to both hydrodynamics and measured sediment transport. This data clearly demonstrate that free large-amplitude long waves influence surf zone morphodynamics not only under accretive conditions, by promoting onshore sediment transport, but also under erosive conditions, by decreasing offshore transport. For the dominant berm-bar feature, the strong surf beat induces offshore transport in the inner surf zone and onshore transport around the outer surf zone and throughout the shoaling zone. In contrast, forced (bound) long waves and wave groups correlated with bichromatic short wave groups play a pronounced role under erosive conditions, increasing offshore sediment transport across the whole beach profile. For accretionary conditions, only a very narrowbanded wave group promotes onshore sediment transport across the whole beach profile, while broader banded wave groups again promote offshore transport. The modified numerical model of Li et al. (2002) provides good predictions of the standing long wave pattern for the long-wave short-wave combinations, but generally poor agreement for the bichromatic wave groups. Similarly, this model performs poorly in terms of predicting the net sediment transport for all waves, even after optimising the sediment transport coefficients. This is because the model cannot predict the correct hydrodynamics around the breakpoint position and does not correctly represent net sediment transport mechanics. Overall, the model does not correctly predict the trends in beach profile evolution induced by the long waves and wave groups. Further, there is little evidence that the long wave nodal structure plays a dominant role. The influence of the free long waves and wave groups is consistent with the concept of the Gourlay parameter, H/wBsBT, as a dominant parameter controlling net erosion or accretion. Free long waves tend to reduce H/wBsBT, promoting accretion, while wave groups tend to increase H/wBsBT, promoting erosion.

Diploma thesis displaying black and white image in false color includes a study of methods and creation of computer software. The main function of the program is to convert the monochrome image into the pseudo colors. This procedure is achieved increasing the diagnostic yield of image. The program may find application in medical field. The pseudocoloring is used several different methods for obtaining the best results, combined with modifications increasing brightness scale image contrast images. The program is created in the programming environment of Visual Studio 2008 and written in C # programming language. Entry program is monochrome images in various formats (JPEG, BMP). The output of the program can be printed in a false-color image or stored image again in several different formats.

I have made an investigation in how I can encourage curiosity in textiles with a specific interest in its structures. I have found that repetition is one efficient way to make a separate building element disappear into its own mass and instead be viewed as a surface. I researched how different surfaces are created by experiment with materials and techniques and looked into the big role tactility plays when curiosity in textiles are created but as well realized that a haptic experience can be reached not only with skin but through the eyes. The experiments and elaborations I made took my ideas beyond my starting point and further than I first could imagine. I explored and questioned hierarchies and values of materials by the way I used and combined them. By doing so I realized and discussed the dilemma of being positive to the idea of letting people experience my work through touching and the issue with sustainability, duration and demolishing the patterns while doing so.  Through this paper I aimed to find a definition for what fiber art can be today. I didn´t find one or totally uniform answer but it seems to me that it´s a movement that stretches over diverse material fields and has an underlying power to push boundaries and traditions and break free from classifications.

Title: Fundamental Painting Author: Claudia Rajlich Department: Institute of Art History Supervisor: Prof. PhDr. Vojtěch Lahoda, CSc. Abstract: This dissertation wishes to define fundamental painting - a term which was coined and a current which was defined by the Stedelijk Museum in Amsterdam in the form of a show of 18 artists of different nationalities in 1975. Like the show, it wishes to give a clear view of a specific new kind of painting of the 1970s, which is "a reflection on the foundations of painting."1 The core of Fundamental Painting is formed by the four painters of American Minimal Art and the show based on a text concerning their work (upon which innumerable texts have been written since). This dissertation focuses on the European part of this "common mentality" as the curators call it, which remains unresearched until today. Its scope is to define: What was it, where did it come from and was it at all? The research is limited to artists in the show (although we conclude that a few should be replaced by others), historical evidence concerning new painting in the 1970s, the critical analysis of texts, artists statements and, above all, the undeniable documentation in the form of the body of works themselves. The existence of Fundamental Painting is proven, its characteristics determined in...

La plupart des côtes de la Terre reculent et 80% sont rocheuses. La prévision du recul des falaises littorales est primordiale afin d’anticiper les risques futurs pour les aménagements littoraux. Cependant, la compréhension de ce recul est difficile car de nombreux paramètres le contrôlent. Des expériences en canal à houle de petite échelle ont été effectuées où nous avons mis en place un massif de sable humide soumis à l’attaque des vagues par sapement. Le but est de comprendre comment l’effet des vagues contrôle l’érosion des falaises. La technique de mesure par ombroscopie a été employée et nous a permis de détecter la surface du sable et la surface libre en fonction du temps. Nous avons ainsi analysé l’influence du forçage des vagues (F, ξ) (où F est le flux d’énergie des vagues incidentes au large et ξ est le paramètre de similitude de “surf”) sur la vitesse de recul de la falaise et sur la profondeur des évènements d’effondrement. La vitesse de recul de la falaise augmente linéairement avec le flux d’énergie F. Les débris de falaise érodés changent la morphologie du fond, les types de morphologie du fond dépendent fortement du paramètre de similitude de “surf” au déferlement, ou encore du paramètre de Dean Ω. Des profils du fond instationnaires présentant une oscillation auto-entretenue de la barre sédimentaire ont été observés. Nous avons de plus étudié l’effet de la granulométrie du sable utilisé : pour un sable plus fin, la falaise est plus cohésive et s’effondre au cours d’évènements de plus grande ampleur. Etonnamment, le recul de la falaise est plus important pour du sable fin. Ceci est probablement dû à une modification de la morphologie du fond conduisant à une dissipation de l’énergie des vagues moins importante. Le volume de sable injecté dans le système a finalement été quantifié, la barre sédimentaire a d’abord été prélevée périodiquement et il a été observé que la vitesse de recul de la falaise vr est constante. Puis, la hauteur de falaise a été modifiée, le recul des falaises est plus important pour des petites falaises. Il semblerait que l’instationnarité d’un profil du fond se déclenche à partir d’un volume seuil de sable érodé. / Most of the Earth coasts recedes and 80 % are rocky. Prediction of sea-cliff recession is essential to anticipate future risks for coastal development. However, it is difficult to understand this recession because many parameters control it. In addition, both the space and time scales are too big for the different mechanisms of cliff erosion to be fully analysed. Experiments in a small-scale wave flume were conducted in which a massif made of wet sand is submitted to wave attack. The aim is to understand how cliff erosion is wave-controlled. The technique of shadow graph measurements was used to detect the time evolution of sand and water surfaces. We have analyzed the influence of wave forcing (F, ξ) (where F is the incident offshore wave energy flux and ξ is the surf similarity parameter) on the cliff recession rate and on collapse event size. The cliff recession rate increases linearly with the wave energy flux F. The eroded cliff materials change the bottom morphology ; the types of bottom morphology strongly depend on the surf similarity parameter at the breaker point, or the Dean parameter Ω. Bottom profiles characterized by unsteady self-sustained sandbar oscillation were observed. In addition, we studied how sand granulometry change the system evolution. Finer the sand is, more cohesive is the cliff and bigger are cliff collapses. Contrary to what was expected, cliff recession is more important for a finer sand : this could be due to a more dissipative bottom morphology built by fine sands. The sand volume within the system changes following cliff collapses and a sandbar removal during particular experiments. The cliff recession rate is constant when the sandbar is removed and decreases with cliff height. It seems that the unsteadiness of the bottom profile is activated when the volume of eroded sand exceeds a threshold value.

Com o advento da internet, a comunicação entre sistemas remotos foi amplamente facilitada, tornando viável a aplicação de sistemas supervisórios através dela, principalmente via protocolo TCP/IP. Embora esses sistemas já sejam empregados na indústria, principalmente utilizando como driver os controladores lógicos programáveis (CLP\'s), a implementação de qualquer sistema mais simples de supervisionamento teria um custo elevado, devido tanto ao preço do hardware quanto do software envolvido. Além disso, os programas supervisórios existentes fornecem um número limitado de recursos de visualização, que se restringem principalmente ao software. Assim, o que se propõe nesse trabalho é um sistema supervisório de baixo custo, via TCP/IP, aplicado em máquinas elétricas, mas que pode ser generalizado na supervisão de outros tipos de sistemas, onde o monitoramento remoto é necessário. Além da exibição convencional dos parâmetros supervisionados através de gráficos e labels, o sistema permite também que esses sejam exibidos através de painéis eletrônicos, fornecendo assim, uma nova interface visual ao usuário com o intuito de facilitar sua supervisão. / The advent of internet simplified the comunication between remote systems, allowing the application of supervisory systems through the internet, mainly using the TCP/IP protocol. Although these systems have already been employed in industry, using the Programmer Logic Controller (PLC\'s) as driver, the implementation of any simple supervisory system could have an expensive cost, due to the prices of hardware and software employed. Moreover, the existing supervisory systems provide limited visual resources, restricted to the used software. So, this work presents a low cost supervisory system, via TCP/IP, applied to electric machines but it can be generalized in the supervision of differents types of systems, where the remote monitoring is necessary. Besides the conventional displaying of the monitored parameters through graphics and labels, the developed system allows the exhibition of the supervisioned parameters using eletronic panels, providing an alternative visual interface to the user so that their supervision becomes easier.
