Full textAbstract:
We are in the golden age for the search for high-redshift galaxies, made
possible by a combination of new instruments and innovative search techniques. One of the major aims of such searches is to constrain the epoch of reionization (EoR), which marks the second major change in the ionization state of the Universe. Understanding the EoR is difficult since whilst it is galaxy evolution which drives reionization, reionization itself influences galaxy evolution through feedback effects. Unraveling the interplay of reionization and galaxy evolution is further complicated by of a lack of understanding of the metal enrichment and dust distribution in high redshift galaxies. To this end, a class of galaxies called Lyman Alpha Emitters (LAEs) have been gaining enormous popularity as probes of all these three processes. In this thesis, we couple state of the art cosmological SPH simulations (GADGET-2) with a physically motivated, self-consistent model for LAEs, so as to be able to understand the importance of the intergalactic medium (IGM) ionization state,
dust and peculiar velocities in shaping their observed properties. By doing so, the aim is to gain insight on the nature of LAEs, put precious constraints on their elusive physical properties and make predictions for future instruments such as the Atacama Large Millimeter Array (ALMA). Using our LAE model in conjunction with a code that builds the MW merger tree (GAMETE), we build a bridge between the high-redshift and the local Universe. We also use SPH simulations (GADGET-2) to study the nature of the earliest galaxies that have been detected as of yet, place constraints on their contribution to reionization, and predict their detectability using the next generation of instruments, such as the James Web Space Telescope (JWST).

Full textAbstract:
United States Lighthouses are being decommissioned by the United States Coast Guard because they are no longer needed as navigational aids. Government agencies and non-profit groups untrained in preservation are assuming control of these aids. These groups need assistance to adequately maintain the lighthouse and prevent major deterioration problems. About 300 managers of lighthouses were contacted for information on how they maintain their lighthouse, including information on shoreline erosion. About 120 replies were received containing maintenance and restoration information, drawings and photographs. The lighthouse system was divided into six geographic regions with similar climatic conditions for closer examination. The replies from the lighthouses regarding common deterioration problems in the construction materials and environmental conditions were used to develop general maintenance guidelines for each geographic region. Lighthouse managers can use these maintenance guidelines to assist them in preserving their lighthouse.Shoreline erosion was examined closely because of its destructive capability. Cape Hatteras Lighthouse in North Carolina was used as a Case Study in combatting erosion.Department of Architecture

This dissertation is aimed to analyze the changes observed in the social uses of lighthouses along the northeast coast of Brazil. We aim to develop geographical and historical approaches to better understand how these monuments have been used at present, within the new social demands were at the beginning of the XXI century. To perform the analysis we organized a historical retrospective on the occupation and use of coastal areas of Brazil, along with theoretical studies concerning the category of territory, fundamental to our discussions. We emphasize that, in addition to desk research, our study consisted of field research, where we could observe the interactions between local people and the headlights. We believe that this research was justified as it helped to organize a scientific knowledge on the subject, generating theoretical support to re-interpret the headlights while coastal monuments and heritage materials from Brazil. Finally, we found that besides material wealth, the lamps can be interpreted as cultural heritages of people living on the Brazilian coast.
Esta dissertação tem como objetivo central analisar as transformações verificadas nos usos sociais dos faróis marítimos do litoral nordestino do Brasil. Objetivamos desenvolver abordagens geográficas e históricas para compreender melhor como estes monumentos tem sido utilizados na atualidade, dentro das novas demandas sociais vigentes no início do século XXI. Para realizar a análise organizamos uma retrospectiva histórica sobre a ocupação e uso dos espaços costeiros do Brasil, juntamente com estudos teóricos referentes à categoria de território, fundamental para nossas discussões. Enfatizamos que além da pesquisa documental, nosso estudo foi composto por pesquisas de campo, onde pudemos observar as interações entre as populações locais e os faróis. Entendemos que esta pesquisa se justificou na medida em que contribuiu para organizar um conhecimento cientifico sobre o tema, gerando subsídios teóricos para re-interpretar os faróis enquanto monumentos costeiros e patrimônios materiais do Brasil. Por fim, pudemos constatar que além de patrimônios matérias, os faróis podem ser interpretados como patrimônios culturais de populações que vivem na costa brasileira.

Full textAbstract:
It is well known that, socioeconomic development in coastal regions is in many respects are more rapid than elsewhere. The rapid development has been the outcome of recognition of these regions as a means providing ideal conditions for relatively cheap transport, food and mineral resource, petroleum, natural gas, agricultural and industrial development, housing and recreation, etc. Therefore, coastal areas are under threat due to forcing function of human activities.
A novel technique addressed scenic evaluation through application of fuzzy logic methodologies to values obtained from checklist that itemized 26 human and physical parameters rated on five-point attribute scale. The methodology enabled calculation of an Evaluation Index (D) which categorizes all sites and statistically best described attribute values in terms of weighted areas.
The methodology developed for coastal scenic evaluation using Fuzzy Logic Approach (FLA) is a very useful tool in making future management plans for coastal areas by simulating different human usages.
With regard to coastal zone management this technique is suitable for evaluating future potential changes especially with regard to influence of coastal structures on the coastal scenery. This work will hopefully be utilized by coastal mangers, planners, academics, governmental agencies, as to improve the especially human usage of the coastal areas also this work will be a tool for the preservation and conservation and the sustainable development of the coastal areas.
For the pilot site, Çirali, D values are calculated and corresponding classes are found for different attributes of parameters rising from the human usage.

Coastal regions are very important because they provide a lot of resources and benefits for all the humankind. Coastal defense structures protect coastal regions from wave attacks. However, the cost of construction such coastal defense structures are very high and need big investments. Hence, to reach the optimum design and minimize the risk of failure has vital importance during the design stage of these structures. Model studies are the most effective tool in optimizing the design of these structures.
Rubble mound coastal defense structures were constructed with assembly of different sizes of armor stones and front slopes. Rubble mound coastal defense structures were designed by Van der Meer

This thesis deals with delay prediction issue between nodes on the Internet. Accurate delay prediction helps with choosing of the nearest internet neighbor and contributes to effective usage of network sources. Unnecessary network load is decreased due to algorithms of delay prediction (no need for many latency measuring). The thesis focuses theoretically on the three main algorithms using coordinate systems - GNP, Vivaldi, Lighthouses. Last one is at the same time the main subject of the thesis too. Algorithm Lighthouses is explored in detail theoretically and in practise too. In order to verify the accurate of delay prediction of Lighthouses algorithm the simulation application was developed. The application is able to compute node coordinates of synthetic network using Lighthouses algorithm. Description of simulation application and evaluation of simalution results are part of practice part of this thesis.

Winds and wind wave climate are two important phenomena for Black Sea basin. Wind wave climate has an important role on design of coastal structures and naval transportation. Despite this fact the wind wave climate is not well known for the Turkish coasts because of limited studies on this subject. The purpose of the present study was to further understand wind and wind wave climate along the Black Sea coastline of
Türkiye. For this purpose wind and wind wave data for every 65 months is obtained from ECMWF for and analyzed for 12 locations situated along Black Sea coast of Turkey. For every location the wind [Berkü

Full textAbstract:
Coastal defense structures have primary importance from obtainabilty of resources and benefits served by the coastal regions point of view. However, the construction of coastal defense structures demand a high amount of investment. Therefore, in order to reduce the risk of collapse of these structures, model studies should be carried during the design process.
In this study, model investigations were carried out on Eastern Black Sea Highway Project regarding the serviceability and damage thus stability parameters. 5 different models were constructed as berm type rubble-mound breakwaters using Van Der Meer&rsquos approach and berm design guidelines, with a scale of 1/31.08 and they were tested both for breaking and non-breaking waves. The experiments took place in the Coastal and Harbor Engineering Laboratory of the Middle East Technical University, Civil Engineering Department. The models were constructed and tested with different berm widths and armor stone sizes forming the back armor layer in order to examine the effect of these design parameters on the stability and serviceability of the coastal defense structure to obtain the optimum alternative cross-section. Cumulative damage was minimum for the cross-section constructed with berm width 15 m assigning the width of the prototype. Water spray and run-up values were also not significant. The test results were confirming with Van Der Meer design approach.

Full textAbstract:
Because little was known about how the masonry lighthouses constructed during the 19th century at exposed locations around the British Isles were responding to wave action, the dynamic response of the Eddystone lighthouse under wave impacts was investigated. Like other so called 'rock lighthouses', the Eddystone lighthouse was built on top of a steep reef at a site that is fully submerged at most states of the tide. Consequently, the structure is exposed to loading by unbroken, breaking and broken waves. When the breaking occurs, wave loading leads to complex phenomena that cannot be described theoretically due to the unknown mixture of air and water involved during the wave-structure interaction. In addition, breaking waves are generally distinguished from unbroken and broken wave due to the fact that they cause impulsive loads. As a consequence, the load effects on the structural response require a dynamic analysis. In this investigation the dynamic response of the Eddystone lighthouse is investigated both in the field and by means of a small-scale model mounted in a laboratory wave channel. In particular, field data obtained by the use of geophones, cameras and a wave buoy are presented together with wave loading information obtained during the laboratory tests under controlled conditions. More than 3000 structural events were recorded during the exceptional sequence of winter storms that hit the South-West of England in 2013/2014. The geophone signals, which provide the structural response in terms of velocity data, are differentiated and integrated in order to obtain accelerations and displacements respectively. Dynamic responses show different behaviours and higher structural frequencies, which are related to more impulsive loads, tend to exhibit a predominant sharp peak in velocity time histories. As a consequence, the structural responses have been classified into four types depending on differences of ratio peaks in the time histories and spectra. Field video images indicate that higher structural frequencies are usually associated with loads caused by plunging waves that break on or just in front of the structure. However, higher structural velocities and accelerations do not necessarily lead to the largest displacements of around a tenth of mm. Thus, while the impulsive nature of the structural response depends on the type of wave impact, the magnitude of the structural deflections is strongly affected by both elevation of the wave force on the structure and impact duration, as suggested by structural numerical simulations and laboratory tests respectively. The latter demonstrate how the limited water depth strongly affects the wave loading. In particular, only small plunging waves are able to break on or near the structure and larger waves that break further away can impose a greater overall impulse due to the longer duration of the load. As a consequence of the depth limited conditions, broken waves can generate significant deflections in the case of the Eddystone lighthouse. However, maximum accelerations of about 0.1g are related to larger plunging waves that are still able to hit the lighthouse with a plunging jet. When compared to the Iribarren number, the dimensionless irregular momentum flux proposed by Hughes is found to be a better indicator concerning the occurrence of the structural response types. This is explained by the fact that the Iribarren number does not to take into account the effects of the wide tidal range at the Eddystone reef, which has a strong influence on the location of the breaking point with respect to the lighthouse. Finally, maximum run up were not able to rise up to the top of the lighthouse model during the laboratory tests, despite this having been observed in the field. As a consequence, the particular configuration of the Eddystone reef and the wind could have a considerable bearing and exceptional values of the run up, greater than 40 m, cannot be excluded in the field.

In this study, numerical modeling of landslide generated tsunami waves in closed basins and their mechanisms are presented. Historical landslide generated tsunamis are investigated and also the governing parameters affecting impulse wave parameters are studied. The numerical model is based on the solution of nonlinear form of the long wave equations with respect to related initial and boundary conditions. In order to validate the outputs of the modeling by NAMIDANCE, empirical formulation is applied to the same cases as the numerical model and the results are discussed. The numerical model is then applied to Pervari Dam artificial reservoir as a case study to investigate the effects of potential landslide into the reservoir. The outputs of the numerical model are compared with empirical formulation results for different approaches of modeling the landslide effect in water body. The critical sections are observed for
overtopping and maximum wave amplitude values and the results are discussed.

Full textAbstract:
There are some empirical formulas used in the design of rubble mound breakwaters to find the weight of armour layer stone. The effect of wave grouping and spectral shape could not put into these design formulas since their effects are still under question. The influences of wave groups and spectral shape on the stability of rubble mound breakwaters have been investigated by several researchers up to now. However, results were not conclusive in these researches, where different wave grouping and spectral shape parameters were used.
This study aims to investigate the influences of wave groups and spectral shape on the stability of rubble mound breakwaters by means of hydraulic model experiments. According to the result of the experiments, the damage
to breakwater armour layer is almost same for different spectrum shapes and pronounced wave grouping, under the condition of similar wave statistics. Experiments also indicated that the wave trains with same significant wave height, H1/3, but with different distribution of the heights of extreme waves which were defined as wave heights higher than H1/3 in this
study, cause different damage levels. Based on these results, extended experiments were conducted to observe the effect of heights of extreme waves in a wave train on the stability of rubble mound breakwaters. Results of the experiments showed that the higher the extreme waves are, the more
destructive the wave train is. By carrying experimental results into design conditions, it was shown that a wave train with high extreme waves may affect the design weight of armour stone.
Finally, in order to achieve more practical tools for engineering applications, occurrence probabilities of extreme waves under different spectral shapes were obtained by a numerical simulation. As a result, for different occurrence probabilities of extreme waves under the most widely used spectrums of PM and JONSWAP, necessary weight of armour stone was given in a range comparing with the formula of Meer. Moreover, it was noted that the spectral shape indirectly affects the stability not due to the wave grouping but due to the extreme waves in a wave train since the occurrence probability of the high extreme waves becomes higher as the spectral shape
becomes narrower under same significant wave height condition.

Full textAbstract:
A numerical model based on one-line theory is developed to evaluate the wind wave driven longshore sediment transport rate and shoreline change. Model performs wave transformation from deep water through the surf zone and computes the breaking parameters. The formula of longshore sediment transport rate used in the numerical model is selected as a result of comparative studies with the similar expressions and the field measurements. Offshore breakwater module of the numerical model is developed to compute the change of shoreline behind single or multiple offshore breakwaters. The validity of the numerical model was confirmed by comparing model results with the shoreline change given within the sheltered zone behind the offshore breakwaters. A series of offshore breakwaters are hypothetically proposed for a case study where a series of groins were constructed whose numerical model results qualitatively matched well with the field measurements. The results of the influences of offshore breakwaters on the shoreline predicted by the model are discussed comparatively with the case study.

Full textAbstract:
Coastal defense structures are built in order to protect valuable coastal regions from the destructive effects of the waves. Due to the cost of coastal defense structures and the economical potential of the coastal regions, failure of such structures could cause loss of high amounts of investment. Therefore in the design and construction of coastal structures, it is of vital importance to achieve an optimum design which is not neither underdesigned nor overdesigned.
In this study, Submerged Berm type coastal defense structures with several different cross-sections were tested for stability under storm conditions. Damage analyses of the different models were carried out to compare the structure characteristics under storm conditions and to obtain the most economical and stable cross-section.
For the model studies, 5 different models were constructed by using Van der Meer&rsquos approach and berm design guidelines. Models were constructed with a model scale of 1:31.08 in the wave flume in the Coastal and Harbor Engineering Laboratory, Civil Engineering Department, METU. The newly designed and optimized berm type structure was proved to be successful and economical.

Full textAbstract:
Climate change and anticipated impacts of sea level rise such as increased coastal erosion, inundation, flooding due to storm surges and salt water intrusion to freshwater resources will affect all the countries but mostly small island countries of oceans and low-lying lands along coastlines. Turkey having 8333 km of coastline including physically, ecologically and socio-economically important low-lying deltas should also prepare for the impacts of sea level rise as well as other impacts of climate change while participating in mitigation efforts. Thus, a coastal vulnerability assessment of Turkey to sea level rise is needed both as a part of coastal zone management policies for sustainable development and as a guideline for resource allocation for preparation of adaptation options for upcoming problems due to sea level rise.
In this study, a coastal vulnerability matrix and a corresponding coastal vulnerability index &ndashCVI (SLR) of a region to sea level rise using indicators of impacts of sea level rise which use commonly available data are developed. The results of the matrix and the index enable decision makers to compare and rank different regions according to their vulnerabilities to sea level rise, to prioritize impacts of sea level rise on the region according to the vulnerability of the region to each impact and to determine the most vulnerable parameters for planning of adaptation measures to sea level rise. The developed coastal vulnerability assessment model is used to determine the vulnerability of Gö
ksu Delta (Specially Protected Area), Mersin that has unique geological, ecological and socio-economical properties which are protected and recognized by both national and international communities.

This thesis attempts to solve a problem identified by the Swedish Maritime administration. The problem consists of birds, more precisely great cormorants, which stain lighthouses with their faeces. Initially an investigation of the great cormorants is performed. The cormorants thrive in great numbers nowadays in the Swedish archipelago after being extinct only a few decades ago. The faeces has a very foul smell and is therefore considered as a problem by maintenance personnel working on lighthouses. It also causes an increased need for cleaning and repainting. An evaluation of previously tested methods for bird deterring was also performed. That evaluation did not discover any methods that had a long lasting effect. Rather it seemed that all methods suffered from habituation. Information about cormorants that tends to avoid being close to base stations for mobile phones was investigated. The investigation could neither confirm such an effect, nor dismiss one. Further investigation was discontinued since it was assumed that the effect was, if it existed, too weak to function as a bird deterring device. Finally bird spikes were discussed. Bird spikes were considered as an interesting direction for future work since it was judged to be a conceivable and permanent solution.Denna rapport har sökt en lösning till, det av Sjöfartsverket, identifierade problemet med skarvfåglar på Sveriges fyrar. Skarvens träck har en mycket frän doft som skapar obehag hos Sjöfartsverkets personal som utför underhållsarbeten på fyrarna. Fågelträcken luktar inte bara illa utan bidrar också till ett utökat behov av rengöring samt målningsarbeten. Inledningsvis undersöktes framförallt skarvfågeln noggrant med syfte att bidra till ökad förståelse för problemet. Det konstaterades bland annat att skarven nu är en ytterst talrik invånare i våra skärgårdar efter att ha genomgått en stark populationsökning under de senaste decennierna. En utvärdering av tidigare testade metoder för att skrämma skarvarna utfördes. Denna utvärdering kunde inte finna någon framgångsrik metod utan visade istället på att en tillvänjningseffekt mot skrämmorna ofta uppstod givet att fåglarna fick tid att vänja sig. Tillvänjningseffekten kunde inte påvisas med säkerhet hos alla de utvärderade metoder men mycket pekade på att skarvar förmodligen alltid kommer vänja sig vid utplacerade skrämmor på fyrar. En hypotes att skarvar verkade undvika att vistas i närheten av basstationer för mobiltelefoni undersöktes. Det visade sig att fåglar innehar ett magnetiskt mineral som mycket väl kan absorbera strålning ifrån master för mobiltelefoni. Dessvärre visade sig osäkerheten om huruvida strålningen på något sätt påverkade fåglarnas beteende vara stor. Om effekten verkligen existerade bedömdes den som alltför ringa för att kunna fungera som en effektiv fågelskrämma. Avslutningsvis behandlas en för skarvarna hindrande åtgärd som med viss framtida utveckling eventuellt kan visa sig vara en slutgiltig lösning på problemet. Den hindrande åtgärden bestod av spikar konstruerade så att skarven inte kan landa på fyren.

The very ideas of “European Union” and “European border” were put to test by the shipments of tens of thousands of human beings in frontline Member States such as Italy and Greece in a period of already great crisis for the EU, also faced with a possible collapse of the Eurozone and the exit of the United Kingdom from the Union.
Another key problem for the EU’s Foreign and Security Policy is the clash between the Eurosphere and Russia in a country that had to decide whether to enter the Euro-Asian Union or sign a Stabilization and Association Agreement (SAA) with the European Union, resulting in coup d’état, civil war, wars of conquest and a growing fear of a Russian invasion, in particular among the Eastern Members of the Union.
This kind of problems are altogether new for the EU and what the Union is doing and will do to tackle them will probably define much of the destiny and scope of the Union itself.
Since its foundation the European Union has been given more and more tools by Member States, becoming a strategic actor with its own autonomous military and civilian capabilities. It has successfully proven its effectiveness all around the world, but today it has to answer calls much closer to home.
What are the tools at its disposal that the Union has this far used to tackle the migrant crisis and the Ukrainian crisis? Can the solidarity clause and the collective defence clause be used in such events? Is the European lighthouse still functioning or is it broken?

In this thesis, the wind-wave records obtained at three locations along the Turkish coasts (Alanya, Dalaman and Hopa) are analyzed. Probability distributions of individual wave characteristics (wave height, wave period and wave steepness) are obtained and compared with the model distributions. Goodness of fit of the observed distributions is checked by Chi-square test and Kolmogorov-Smirnov tests. Joint probability distribution of individual wave heights and periods is also studied and compared with the theoretical distributions. The relationships among various statistical wave height parameters and statistical wave period parameters are investigated and compared with the theoretical and reported values.

In this study, The Beach Dewatering System, a relatively recent technology to combat beach erosion, which is proposed as a practical alternative to more traditional shoreline stabilization methods, is investigated and an informative overview on the genesis, development and recent use of this technique is provided. On the basis of the link existing between the elevation of beach groundwater and erosional or accretionary trends at the beach face, a numerical model that simulates groundwater flow in a coastal aquifer under beach drainage is presented. In this model, the seaward boundary of the domain is considered to be tidally fluctuating in a large scale to represent the occurrence of seepage face significantly. The unsteady groundwater flow equation is solved numerically using the method of finite differences. The results clearly showed that the water table being lowered caused the reduction of the seepage face which is the main aim of Beach Dewatering projects. The positional design parameters, i.e. horizontal and vertical location of the drain, are also investigated by utilizing an efficiency index. It is observed that the system efficiency decreased as the drain is shifted landward. The results also indicated that, the efficiency slightly increased with the vertical drain elevation.

Full textAbstract:
In this study, available coastal models are briefly discussed and under wind waves and a numerical shoreline change model for longshore sediment transport based on &ldquoone-line&rdquo
theory is developed. In numerical model, wave diffraction phenomenon in one-dimensional modeling is extensively discussed and to represent the irregular wave diffraction in the sheltered zones of coastal structures a simpler approach based on the methodology introduced by Kamphuis (2000) is proposed. Furthermore, the numerical model results are compared with analytical solutions of accretion and erosion at a single groin. An application to a case study of a groin field constructed to the east side of Kizilirmak river mouth, at Bafra alluvial plain, is carried out by the numerical model. The results of comparisons show that the numerical model is in good agreement with the analytical solutions of shoreline changes at a groin. Similarly, numerical model results are compared with field data of Bafra and it is shown that they are in good agreement qualitatively. Therefore, the numerical model is accepted to be capable of representing of shoreline evolution qualitatively even for complex coastal regions.

Full textAbstract:
In this study, a numerical model &ldquoModified Coast-Structure Interaction Numerical Model&rdquo
(CSIM) is developed with an implicit approach to determine the shoreline changes due to wind wave induced longshore sediment transport under the presence of groins, T-groins and offshore breakwaters by making modifications on the explicit numerical model &ldquo
Coast-Structure Interaction Numerical Model&rdquo
(CSI). Using representative wave data transformed to a chosen reference depth from deep water, numerical model (CSIM) simulates the shoreline changes considering structure interference. Breaking and diffraction within the sheltered zones of coastal structures defined for offshore breakwaters by using vectorial summation of the diffraction coefficients and as for T-groins shore-perpendicular part forms a boundary to define the shoreline changes seperately at two sides of the structure. Numerical model, CSIM is tested with a case study by applying in Bafra Delta, Kizilirmak river mouth at Black sea coast of Turkey. Numerical model simulations show that model results are in good agreement qualitatively with field measurements.

Full textAbstract:
Block type quay walls are commonly used as berthing structures both in Turkey and worldwide. In this study, stability analysis of block type quay wall is carried out using pseudo-static method. A computer program named QSAP (using Excel spreadsheet) has been developed for the design of block type quay walls. QSAP has been prepared based on the rules of Turkish Seismic Design Codes for Coastal Structures, 2008. Reliability of this program is verified by a comparative study of Derince Port block type quay wall, damaged in Marmara earthquake (1999), with manual solution and field measurements. A newly introduced placement methodology &ldquoKnapsack&rdquo
is also studied with QSAP and the results are compared with the conventional placement method.

In this study, new design approaches are introduced for the seismic design of block type quay walls after reviewing the conventional methodologies. Within the development of the new design approaches an inverse triangular dynamic
pressures distributions are applied to define both seismic earth pressures and seismic surcharge pressures. Differently from the conventional design methodology, the hydrodynamic forces are taken into consideration while dynamic forces are specified and equivalent unit weight concept is used during
the both static and dynamic calculations Compatibility of this new design approaches are tested by case studies for the site and it is seen that the numerical results are in good agreement qualitatively with field measurements.

Full textAbstract:
The wind and wave (wind wave/swell wave) climate has an important role in the design and operation of coastal and marine structures, harbors and ports. The objective of this study is to identify the statistical characteristics of the winds, wind waves and swell waves in Eastern Mediterranean, and coastline of Türkiye. For this purpose, the data of wind speed and direction, swell and wind wave height, period and direction for a certain duration with the six hours time intervals are obtained from ECMWF for the wind and wave climate computations. The data covers the area of eastern Mediterranean region. In order to compute the wind and wave climate at any selected coastal location, a software is developed by Serhan Aldogan in his MSc thesis. For every location, the wind wave roses, significant height of wind wave and swell wave versus mean period of primary wind directions, extreme probability analysis and distribution, and log-linear cumulative probability analysis and distributions is presented, compared and discussed. By the help of the specifically developed software, it is possible and convenient to analyze the wind and wave climate using ECMWF data at any coordinate.

This thesis analyzed the new parameter hydrodynamic demand representing the damage of tsunami waves on structures and coastlines,maximum positive amplitudes and current velocities occurred during tsunami inundation by using the numerical model TUNAMI-N2. Regular shaped basins were used with two different bottom slopes in analyses in order to understand the behaviour of tsunami wave and investigate the
change of important tsunami parameters along different slopes during tsunami inundation. In application, different initial conditions were used for wave profiles such as solitary wave, leading elevation single sinusoidal wave and leading depression sinusoidal wave. Three different initial wave
amplitudes were used in order to test the change of distribution of the hydrodynamic demand. The numerical results were compared and discussed with each other and with the results of existing analytical and experimental studies.

Full textAbstract:
Turkey, with its climate, protected bays, cultural and environmental resources is an ideal place for yacht tourism. Subsequently, yacht tourism is increasing consistently. Yacht tourism can cause unmitigated development and environmental concerns when aiming to achieve tourist satisfaction. As the demand for yacht tourism intensifies, sustainable development strategies are needed to maximize natural, cultural and economic benefits.
Integration of forecasts to the strategic planning is necessary for sustainable and use of the coastal resources. In this study two different quantitative forecasting techniques - Exponential smoothing and Auto-Regressive Integrated Moving Average (ARIMA) methods were used to estimate the demand for yacht berthing capacity demand till 2030 in Turkey.
Based on environmental, socio-economic and geographic data and the opinions gathered from stakeholders such as marina operators, local communities and government officials an allocation model was developed for the successful allocation of the predicted demand seeking social and economical growth while preserving the coastal environment. AHP was used to identify and evaluate the development, social and environmental and geographic priorities. Aiming a dynamic plan which is responsive to both national and international developments in yacht tourism, potential investment areas were determined for the investments required to accommodate the future demand. This study provides a multi dimensioned point of view to planning problem and highlights the need for sustainable and dynamic planning at delicate and high demand areas such as coasts.

This study analyzes the parameter &ldquohydrodynamic demand&rdquo
that is also defined by the square of Froude Number representing the damage of tsunami waves on structures and coastlines, and other hydrodynamic parameters, i.e., the distribution of instantaneous flow depths, runup values and the direction of maximum currents, occurred during tsunami inundation by using advanced numerical modeling. The analyses are performed on regular-shaped basins with different bottom slopes and real-shaped topographies using different wave shapes, wave periods and types. Various orientation and amount of coastal and land structures are used in simulations to have results for many different cases. This study provides the opportunity to define the damage of level in residential areas and to test the performance of coastal protection structures. The behavior of tsunami hydrodynamic parameters in shallow and inundation zone is investigated and a correlation is obtained between the average maximum values of square of Froude Number with the wave characteristics and sea bottom slope. After determining hydrodynamic parameters in regular shaped basins, a case study is applied by modeling the March 11, 2011 Great East Japan Tsunami with finer resolution in nested domains. The determination of hydrodynamic parameters in inundation zone during 2011 Japan event is performed in one of the most damaged coastal city Kamaishi.

Find full textAbstract:
Historic rock-mounted lighthouses play a vital role in the safe navigation around perilous reefs. Their longevity is threatened by the battering of waves which may be set to increase with climate change. The protection of this historic heritage needs the identification of both structural dynamic parameters (natural frequencies and shape modes), and of the worst-cases wave load combination, able to affect that natural frequencies. This dissertation was developed during a period of five months at University of Plymouth, along with the researching team of the project STORMLAMP. The project is divided in three parts; the first involving a meteocean analysis, developed by means of peak over threshold technique, aimed to address realistically a test campaign held afterwards. The second, focused on the dynamic analysis of the Dubh Artach lighthouse and was developed by means of a Matlab toolbox provided to the group by Prof. Brownjohn from Exeter University, partner of the project as well. It is aimed on one hand to detect the dynamic properties of the structure and, on the other hand, to recognize eventual directionality in the structural response. The third phase was held at Plymouth University laboratory “COAST”. During this phase, a laboratory campaign, involving more than 100 tests, allowed to perform a parametric analysis aimed to identify the parameters, of an extreme wave, that influence more the impact force and that the wave exerts on the structure. To extract impact time history, force signals were decomposed by means of Empirical mode decomposition and Duhamel integral algorithms. Image analysis, moreover, allowed to locate run-up caused by those waves upon a steel cylinder and to integrate a study of the run-up as well. The analysis led to several considerations useful on one hand for the prediction of the worst-case loading of the Dubh Artach lighthouse and, on the other hand, for the introduction of the NewWave theory for the design of coastal structures.

Full textAbstract:
The Point Sur Lighthouse is an unreinforced stone masonry building completed in 1889 on the central coast of California. The lighthouse is listed on the National Register of Historic Places and is still an active aid to navigation. The original first-order Fresnel lens was removed from the lantern room and placed in safekeeping due to its high risk of damage in the event of a strong earthquake. The lens has been approved to return to its original setting but the seismic performance of the building must first be assessed in order to ensure the safety of the lens and lighthouse, specifically the out-of-plane behavior of the unreinforced masonry walls, the implementation of possible seismic retrofit schemes, and the effects of the lens’s added weight.
This research focuses on the dynamic behavior of the lighthouse in its current state and the changes in the dynamic behavior each of the proposed seismic retrofit schemes might cause. For the purposes of this research, dynamic behavior is considered as natural frequencies, mode shapes, and related structural properties. The dynamic behavior of the lighthouse was assessed using two main methods: forced vibration testing and finite element computer modeling. Forced vibration testing is a nondestructive testing method that can be used to directly characterize dynamic behavior of a structure, and finite element computer modeling is useful for the design and simulation of dynamic behavior of both new and existing structures. The combination of these two methods on the Point Sur Lighthouse will work to develop and prove state-of-the-art seismic retrofitting techniques.

Full textAbstract:
Les phares représentent un patrimoine culturel et technique inestimable qu'il faut conserver le plus longtemps possible. La thèse se concentre sur le cas des phares en maçonnerie construits le long du littoral, exposés aux actions environnementales mais pas à l'action des vagues. Ces phares, construits pour la plupart au cours du 19ème siècle et jusqu'au tout début du 20ème siècle, présentent des désordres structurels. Le but de la thèse est de développer une méthode de diagnostic des pathologies observées sur la base d'un plan de surveillance mis en œuvre sur ouvrage. La thèse est construite sur une étude de cas : le phare de l'Ile Vierge qui est le plus haut phare en pierre d'Europe avec ses 80 m de hauteur. Il a été construit entre 1897 et 1902 sur un ilot situé à l'extrémité Ouest du Finistère avec deux pierres locales (granite et kersanton). En 2011, le Service des Phares et Balises de Brest a remarqué la présence d'un schéma de fissuration verticale en tête de la tour sur toute la hauteur du mur qui supporte la lanterne par l'intermédiaire de 16 montants métalliques encastrés sur la périphérie. Ces travaux de thèse ont pour objectif de trouver l'origine des fissures au moyen de l'analyse des données issues de l'instrumentation installée sur le phare pendant toute la recherche, et de formuler une méthodologie de diagnostic pour ce type d'ouvrage. Les hypothèses formulées et étudiées sont l'action du vent et l'action thermique. La méthode de recherche pluridisciplinaire inclut la caractérisation mécanique des roches, le calcul des actions mécaniques agissantes sur la structure, le recueil des données issues de l'instrumentation installée sur site et l'étude statistique par corrélation multivariable. La variation de l'ouverture des fissures est étudiée au regard des actions prises en compte. De plus, la démarche permet de démontrer comment les actions thermiques cycliques et les phénomènes de fatigue peuvent générer des contraintes proches de la résistance en traction du kersanton et donc expliquer l'apparition des fissuresLighthouses represent an invaluable cultural and technical heritage that must be preserved as long as possible. This manuscript thesis focuses on the case of masonry lighthouses built over the coast, which are exposed to environmental actions but not to the wave action. These lighthouses, mostly built during the 19th century and until the beginning of the 20th century, show structural disorders. The aim of the thesis is to formulate a structural diagnosis method based on a structural health monitoring implemented on the structure. The case study of the research is the Ile Vierge lighthouse, currently being the tallest stone masonry lighthouse in Europe due to its 80.0m high. It was built between 1897 and 1902 on an island located at the West of Finistère with two local construction materials (granite and kersanton stones). In 2011, Service des Phares et Balises notices the presence of a vertical cracking pattern in the upper part of the tower. The cracks prevail over the entire height of the lantern's basement wall, where the lantern support is fixed by 16 metal embedded anchors. This thesis focuses to find the origin of cracks by data analyses from the structural health monitoring implemented on the lighthouse and to formulate a diagnosis methodology for this type of buildings. The hypotheses studied are wind actions as well as thermal actions on the structure. The multidisciplinary research method considers the mechanical characterization of rocks, the calculation of mechanical actions presents on the structure, the collection of data from the health structural monitoring and the statistical analysis by multivariable correlation. The opening crack is analyzed according with the actions considered. In addition, the approach exposes how cyclic thermal actions and fatigue phenomena can generate stresses close to the tensile strength of kersanton and therefore explain the crack vertical pattern

Virginia Woolf is considered one of the most important British writers. Besides showing in her texts an enormous concern with breaking the limit space-time, she engaged in a process of literary experimentation in order to represent the objective and subjective reality of the invented subjects. Discuss the construction of memory-images and how it is re-signified in the opuses To The Lighthouse (1927) and The Waves (1931) by Virginia Woolf is the main interest of this dissertation, which starts from the assumption that everything begins in the memory and ends in the image. As noted Filloux (1959, p.122): "for a reminder to reappear in consciousness, it has to come down from the heights of the memory to the moment where the action takes place." This action, as evidenced in the interior life of the characters in both narratives, has a perceptual bias that is realized in the image. At first, the paper discusses about the different conceptions of the memorialistic universe, considering its intrinsic relationship with time and space. Next, it explores the woolfian language and its proximity to impressionism/Post-Impressionism, and only then makes a more fruitful analysis of the image represented not only in memory of the characters, but in the Woolfian narrative itself. In order to achieve the objectives of this study, the research is supported mainly on the bibliography of Henri Bergson (2006), once its concepts enable greater understanding of the constitution of memory-images. Placed that woolfian narratives configure themselves into a true poetics of space, this paper also supports itself on some propositions of Gaston Bachelard (2008), in particular those exploring the creative imagination. On the pictorial questions, the work privileges, among other authors, the impressionist concepts by Meyer Schapiro (2002). The way Virginia Woolf represents the psychological universe of her characters, as well as the simultaneity between the interior and exterior, which are remarkable in their literary style, lead us to think that all recollection conducts itself to a type of pictorial construct, that is, the images constructed in the narratives from the stream of consciousness can be viewed as if they were literally framed. Thus, both the novels discussed here show that literature influenced by the Impressionist aesthetic implies a new way to view pictures.
Virginia Woolf é considerada uma das mais importantes escritoras inglesas. Além de mostrar em seus textos uma enorme preocupação com a quebra do limite espaço-temporal, ela empenhou-se num processo de experimentação literária a fim de representar a realidade objetiva e subjetiva dos sujeitos por ela inventados. Discorrer sobre a construção das imagenslembranças e como ela é ressignificada nas obras To The Lighthouse (1927) e The Waves (1931) de Virginia Woolf é o interesse principal dessa dissertação, que parte do pressuposto de que tudo começa na memória e termina na imagem. Como constata Filloux (1959, p.122): “para que uma lembrança reapareça na consciência, é preciso que ela desça das alturas da memória até o ponto em que se realiza a ação”. Essa ação, tal como evidenciamos na vida interior das personagens de ambas as narrativas, possui um viés perceptivo que se concretiza na imagem. A princípio, o trabalho discorre sobre as diferentes concepções acerca do universo memorialístico, considerando a sua intrínseca relação com o tempo e o espaço. A seguir, explora-se a linguagem woolfiana e a sua proximidade com o mpressionismo/pósimpressionismo, para só então fazer uma análise mais profícua da imagem, representada não só na memória das personagens, mas na própria narrativa woolfiana. A fim de alcançar os objetivos desse trabalho, a pesquisa apoia-se principalmente na bibliografia de Henri Bergson (2006), uma vez que seus conceitos possibilitam uma maior compreensão acerca da constituição das imagens-lembranças. Posto que as narrativas woolfianas configuram-se numa verdadeira poética do espaço, o trabalho também se apoia em algumas proposições de Gaston Bachelard (2008), em específico, àquelas que tratam da imaginação criadora. Sobre as questões pictóricas, o trabalho privilegia, entre outros autores, as concepções impressionistas de Meyer Schapiro (2002). A maneira como Virginia Woolf representa o universo psicológico de suas personagens, bem como a simultaneidade entre o interior e o exterior, que são marcantes em seu estilo literário, nos levam a pensar que toda lembrança encaminha-se para um tipo de construto pictórico, ou seja, as imagens construídas nas narrativas a partir do fluxo de consciência podem ser visualizadas como se estivessem literalmente emolduradas. Assim, ambos os romances aqui discutidos mostram que a literatura, influenciada pela estética impressionista, implica em uma nova maneira de ver imagens.

Full textAbstract:
Les textes de virginia woolf portent en eux des inscriptions de leurs propres geneses. Plus precisement, les scenes de l'ecriture tissees a travers la structure diegetique de ces textes fonctionnent a la fois comme des representations de la genese de l'ecriture et comme des mises en scene de cet evenement. Dans chaque cas, la genese de l'ecriture accompagne l'engendrement du sujet. On pourrait donner a un des elements qui figure de facon decisive a travers ces mises en scene, le nom de "loi". Il s'agit d'une force exterieure qui, en premier lieu, barre le chemin, en arretant le processus de l'ecriture pour finalement, et de facon paradoxale, participer a la constitution de l'ecriture produite et du sujet qui emerge. Cette etude se propose premierement de comprendre ce qui fonctionne commela "loi" dans les textes analyses et tente ensuite de decouvrir comment l'ecriture et le sujet se mobilisent pour negocier un passage au-dela de l'obstacle impose. Elle vise a la fois ce qui fonctionne comme une force de loi externe et interne au texte : d'abord, ce qui vraisemblablement intervient de l'exterieur du texte pour empecher son engendrement, et ensuite ce qui constitue la force de loidu texte, ce qui accorde a un texte la possibilite de fonctionner lui-meme comme une force de loi en imposant la singularite de son propre idiome vis-a-vis des conventions pre-etablies ou il prend son depart. La mise en relation des trois textes de woolf qui forment l'objet de cette etude, a savoir, the voyage out, to the lighthouse, et between the acts, rend manifeste une evolution decisive du rapport a la loi vis-a-vis de l'idiome poetique aussi bien que du sujet. Pour les trois textes etudies ici, la nature de la negociation avec la loi devant laquelle chacun se trouve est determinante dans la construction de sa loi propre. The voyage out se termine par une dissociation entre les dimensions singulieres et universelles dont il a besoin pour inaugurer sa propre force de loi. To the lighthouse, en revanche, n'evite pas, mais plutot se tourne vers la negociation d'un rapport avec les forces de loi exterieures auxquelles il est confronte. Dans between the acts, la loi a laquelle l'idiome du texte est confronte est la sienne. L'idiome de ce texte fait appel aux lois contradictoires qui le constituent, les invitant a un jeu de l'entre-deux afin de degager du conflit, la possibilite de

This dissertation is a performative exploration of experience within our technoscientific--that is, technologically and scientifically saturated--world. Drawing upon posthumanism and cyborg studies and working through specific, mutated versions of performative inquiry and phenomenology, I aim to encourage creative public participation in technoscientific discourse. That is, I apply an adapted method (cyborg phenomenology) to my own staged personae performances of nonhuman entities in order to investigate technoscientific experience from a less anthrocentric perspective. My goal is to interrogate my performance experience in order to better understand the dynamics of agency and relationship within our technologically infused world, and to employ performance and performative writing as pedagogical tools for educating others about these dynamics. This document might be best read as an example of performative inquiry as a useful approach to the study of technoscience and its consequences. As a whole, this dissertation is a call for, theorization with, and performative demonstration of artful participation in the multi-layered discourses of technology and science that impact the lives of all beings in our world. It is an experiential experiment, an exploration of possibility, and a beginning.

Full textAbstract:
Autor no autoriza el acceso a texto completo de su documento.The issue of dominance and submissiveness in Virginia Woolf’s (1927) To The Lighthouse will be the center of this study because of a number of reasons. Virginia Woolf shows an interesting mixture composed of governing and subservient figures in her novels. These first ones are represented mainly by men such as Mr. Ramsay, and the second ones, by women such as Mrs. Ramsay. The creation of this dichotomy is clearly influenced by the Post-Victorian environment in which Woolf grew up and wrote. There is an innovative way to present us these characters because she shows us the reality of dominance and obedience in a sarcastic way, that is, by saying something when she wants to state the opposite. Virginia Woolf’s novels are characterized by the presence of governing and subservient protagonists. This happens due to the context in which she created her novels, that is, the Post Victorian period. Nevertheless, there is an attempt to balance these two complementary forces, dominant and submissive, in order to criticize the established order. She did it in a subtle way, though; the social conventions at that period prevented her from going any further. The aim of this essay will be to discover the element that makes dominance and submission to be apparent in the characters, this key element could be the post- Victorian society or a personal contribution of the author, specifically a modern strategy, to change society from the individual rather than system. This work will be a contribution in the sense that as a starting hypothesis is that dominant and submissive figures in Woolf’s novels are presented in a non-traditional fashion. Therefore, one of the contributions of exploring these seemingly ascendant and passive representations would be to encourage a more realistic approach to characters, leaving aside stereotypical notions. Another contribution of this study, which lies on the examination of artistic and aesthetic motivations, is related to aesthetic purposes of the author. However, these are treated in an innovative way, not explaining much about their nature with practical language, but using rhetoric and poetic resources. Finally, it is important to relate these dichotomies to Woolf’s Modernism.

Para se caracterizar a área, os parâmetros físicos e químicos pH, Eh, salinidade e temperatura foram determinados. A concentração de clorofila a também foi determinada (0,004 ug.L menos 1) classificando o ambiente como oligotrófico no momento da coleta. O total de sólidos em suspensão apresentou uma concentração baixa de Hgtotal (156,78 mais ou menos 0,61 ug.kg menos 1). Dentre a biota analisada a molusca gastrópoda apresentou a maior concentração nos seus tecidos moles (82,75 mais ou menos 5,78 ug.kg menos 1). Entretanto a sua principal fonte de alimento, o mexilhão apresentou uma concentração de Hgtotal quatro vezes menor (19,13 mais ou menos 0,58 ug.kg menos1) e a sua postura aproximadamente onze vezes menor (7,36 mais ou menos 0,71 ug.kgmenos1). A partir destes dados conclui-se que houve a transferência trófica do Hgtotal entre os organismos estudados.
In order to verify the trophic transfer of mercury, the concentrations of total mercury (Hgtotal) were determined in the aggregated fauna from a sand reef region formed by polychaetes, Phragmatopoma lapidosa. In addition to the aggregated fauna, mussel (Perna perna), green algae (Ulva spp.), porcelain crab (Pachycheles sp) and gastropod (Thais haemastoma) and its posture, Hgtotal were also determined in the suspended particulate matter and in the superficial sediments from the region of the Lighthouse of St. Tomé Reef, Northern Rio de Janeiro State (22 04 52 S, 041 06 59 W). This oceanic area belongs to a transitional faunistic region, which presents a great biodiversity. Hgtotal in the biotic and abiotic samples were determined by a cold vapor atomic absorption spectrometry, coupled to a flow injection system, Perkin Elmer FIAS 400. In order to characterize the superficial water layer of the region, some physical and chemical water parameters (pH, Eh, salinity and temperature) were determined. At the moment of the water sampling, the concentrations of chlorophyll a (0.004 ug.L less 1) in the water column indicated that the trophic state was oligotrophic. The total suspended particulate matter showed a low mean of Hgtotal (156.78 more or less 0.61 ug.kg less 1). The gastropod soft tissues presented the highest Hgtotal (82.75 more or less 5.78 ug.kg less1) and were approximately fourfold higher than those found in its main food items, the mussel (19.13 more or less 0.58 ug.kg less 1). However, mercury concentrations in gastropod posture (7.36 more or less 0.71ug.kg less 1) were eleven times lower than those found in gastropod soft tissues. From these data, it suggests that there is trophic transfer of mercury between organisms studied.
