Karamanlıca bir tabirname hakkında
No full textÖzetKaramanlıca ya da Karamanlı Türkçesi olarak adlandırılan Yunan harfli Türkçe ile pek çok eser kaleme alınmıştır. Bu eserler üzerine yapılan analitik bibliyografya çalışmaları bunların daha çok dinî içerikli yayınlar olduğunu göstermektedir. Din dışı eserler daha az olmakla birlikte edebiyat, felsefe, tıp, eğitim ve folklor alanlarıyla ilgili kitaplar ve dergiler de yayımlanmıştır. Bu eserlerden bir tanesi de 1885 tarihli Rüya Kitabı’dır. Müellifi S. İgnatiadis’tir. Adından anlaşılacağı üzere çeşitli kaynaklardan derlenmiş rüya yorumlarından oluşan 30 sayfalık bir tabirname (oniromansi)’dir. Matbu esere ulaşılamamış, ancak kitabın siyah beyaz fotoğraflarını inceleme imkanı elde edilmiştir. Bugüne kadar üzerinde herhangi bir çalışma yapılmayan bu eserden ilk bahseden araştırmacı Evangelia Balta’dır. Balta, Karamanlidika Additions (1584-1900) kitabında yayınla ilgili bibliyografik bilgi vererek ön sözünden alıntı yapmıştır.İstanbul’da S. İgnatiadis Matbaası’nda basılan eserin \"Prologos\" (Ön Söz) bahsinde müellif rüya yorumlama sanatınının bütün milletler tarafından kabul görüp uygulandığını, Mısırlılar, Yunanlar, Asurlular, Keldaniler ve Acemler’in rüya yorumlamayı ilim olarak saydıklarını belirtir. Ayrıca Eski Yunanlar devrinde insanların rüyalarını tabir ettirmek amacıyla Livadya’daki \"Trofonios Mağarası\"na gittiklerini de ifade eder. Ön Söz bahsinden sonra Rüya Kitabı başlığı altında alfabetik sıra ile rüyalar yorumlanır. Sade bir dille yazılmış olan bu eseri, halkın inancını, dünya görüşünü, gelenek-göreneklerini göstermesi bakımından folklorik bir malzeme, Türkçe söz varlığı açısından da önemli bir kaynak olarak görmek mümkündür.Bu bildiride, İgnatiadis’in Rüya Kitabı adlı eserinin muhtevası, yapısı, dili ve üslubu hakkında bilgi verilmiştir. Ayrıca metinden çeviri yazı yapılarak seçilmiş tabirler incelenmiştir. Sonuç bölümünde ise eserden hareketle dil, edebiyat ve kültür çalışmalarında folklorik malzeme içeren bu tür tabirnamelerin tespitinin, neşrinin önemi dile getirilmiştir.

Analytical bibliography studies on these works show that they are mostly religious publications. Books and journals on literature, philosophy, medicine, education and folklore were also published, although non-religious documents were less common. One of these books, written by S. Ignatiadis is the Rüya Kitabı (Oneiromancy) in 1885. It is a 30-page phrasebook consisting of dream interpretations, as the name suggests, compiled from various sources. The original publication was not available but black and white photographs of it were examined. Evangelia Balta is the first researcher to talk about this work, which has not been studied until today. Balta quotes some parts of the introduction of this book and provides bibliographic information about this publication in her book Karamanlidika Additions (1584-1900).This book was published in S. Ignatiadis Printing House in Istanbul. In \"Prologos\" (Preface), the author states that the art of oneiromancy (dream interpretation) was accepted and practiced by all nations, amongst them, the Egyptians, the Greeks, the Assyrians, the Chaldeans and the Persians regarded dream interpretation as a science. It also states that during the Ancient Greek era, people went to the \"Cave of Trophonius\" in Livadeia to have their dreams interpreted. Following the Preface, dreams are interpreted in alphabetical order under the title of Rüya Kitabı (Dream Book). This work, written in plain language, can be regarded as a folkloric material in terms of showing the beliefs, the worldview, the traditions and the customs of the people, as well as, an important source in terms of Turkish vocabulary .In this paper, information is given about the content, the structure, the language and the style of Ignatiadis\"s book called Rüya Kitabı. In addition, a selection of dream interpretations were evaluated by transcribing the original text. In the conclusion part, the importance of determining and publishing such dream interpretations containing folkloric material in language, literature and culture studies has been expressed, based on the above mentioned work.

Effects of acute microinjections of thyroid hormone to the median preoptic nucleus of adult male rats on total sleep, loco-motor activity, and core body temperature
No full textOne clinical effect of dysthyroidism is often the disruption of normal sleep. The hypothalamus, more specifically the Median Preoptic Nucleus (MePO) contains highly restricted neuroanatomical clusters of sleep-active neurons. These neurons express GABAA receptors, which have previously been implicated in the onset and maintenance of sleep. T3 has been shown to inhibit the actions of benzodiazepines in electrophysiological experiments. The current experiment served to investigate possible non-genomic action of T3 microinjections to the MePO on sleep behavior over a series of 48-hour intervals, comprised of one 24-hour control and one 24-hour experimental interval. Injections to the MePO, of varying doses of T3 caused significantly different response effects on REM, non-REM, core-body temperature, and locomotor activity. The date indicated that T3 at 1 µg and 3 µg T3 injections caused a significant decrease in Total Sleep (TS) (P<0.0001 and P< 0.0001 respectively). T3 yielded a significant decrease in non-REM sleep (NREMS) for the doses of 1 µg, and 3 µg injections of T3 (P <0.0001 and P<0.0001 respectively along with an increase in REM sleep (REMS) in doses of 1 µg, and 3 µg T3 injections (P<0.03 and P<0.0001 respectively) within 24 hours of injection. These effects may be due to possible neurotransmitter or neurosteroid-like properties of T3 in the brain, or they may be from inhibitory protein phosphorylation effects found in previous experiments. Since the effects of T3 were demonstrated after acute injections, the data is consistent with possible non-genomic actions of thyroid hormones in the adult brain.M.S.Includes bibliographical referencesby Phillip Giannopoulo

Nutritional characterization of carobs and traditional carob products
No full textTwenty traditional carob products were measured for their nutritional composition, and their results were compared with the pulp of Cypriot carob cultivars. Moisture, ash, fat, proteins, sugars, dietary fibers, minerals, caffeine‐theobromine, carbohydrates, and energy value were determined. Fluctuations of the nutritional composition values based on the ingredients’ chemical synthesis and product manufacturing process were noted. Only 60% of the products had a label indicating their nutritional value, and the majority of them (75%) were consistent with that of labeling. Chemometric analyses distinguished the carob products according to their type and the discriminator components highlighted their particular nutritional value. Carobs can be characterized as functional foods with low‐fat content, high content in dietary fibers, and high content and/or source of minerals; however, carob products partially satisfied those health and nutritional claims as expected. This pilot research contributes to the nutritional estimation of carob and highlights the traditional carob products
Hierarchical Mapping: A Rao-Blackwellized Particle Filter based hierarchical SLAM framework
No full textMobile robots need to be fully autonomous in order to perform their tasks inside their environment. To do that, robots need to have an understanding of their environment, so that they can successfully localize and navigate themselves within it. The understanding of the robots' environment is created by solving the SLAM (Simultaneous Localization And Mapping) problem. The SLAM problem is usually approached using probabilistic laws; both the robot's path and the environment are estimated and represented by probability distributions. The estimate of the environment is incorporated into a map, which could either be one global map or a network of smaller connected local maps. In small areas where the sensors' errors and inaccuracies remain low, the creation of one global map is preferred. However, as the area grows larger, the global map becomes inaccurate due to accumulated errors. Therefore the strategy of creating a network of local maps is employed. Even though this strategy produces low error results, there is still a limit beyond which it does not scale. Specifically, as the mapping area grows even wider, the number of local maps increases which in turn causes the amount of required memory to increase. In addition, when it comes to loop closure or in other words the procedure of estimating whether the robot returned to a previously visited point in the map, the required computational power increases linearly or sometimes quadratically with respect to the number of local maps.Consequently, SLAM algorithms suffer from scalability problems, especially when the mapping area becomes too large. Since robots are real-world devices, mapping solutions should be efficient and applicable to the robot's resources, even when these resources are limited. In this thesis we propose a framework which addresses this scalability issue, aiming to reduce the computational needs and memory usage during the SLAM procedure. Additionally, our framework intends to facilitate loop closure, which can become troublesome in large environments. Our framework uses multiple sensors and creates a network of hierarchically structured local maps. In order to assess our framework, we compare it to a technique which produces a network of non-hierarchically structured local maps. Our experiments show that in large areas our framework works ideally; the speedup is encouraging and the RAM memory overhead is negligible or conditionally lower
Associating Borehole Radar Imaging with Petrophysical Properties for a Mud-Contaminated Reservoir
No full textIn the phase of oil drilling, mud filtrate penetrates into porous formations and alters the pore fluid properties. This complicates well logging exploration, and inevitably gives rise to shift in reservoir estimation. Logging engineers deem mud invasion a harm and attempt to eliminate its impact on logging data exploration. However, from our point of view, the mudcontaminated parts of the formation do also carry some valuable information, notably with regard to the key hydraulic properties. Therefore, if adequately characterized, mud invasion effects, in turn, could be utilized for reservoir estimation. Typically, the invasion depth critically depends on the formation porosity and permeability. To achieve this objective, we propose to use borehole radar to determine the mud invasion depth considering a high spatial resolution of ground-penetrating radar (GPR) compared with the conventional logging tools. We implement numerical investigations on the feasibility of this approach by coupling electromagnetic (EM) modelling with fluid flow modelling in an oil-bearing formation disturbed by mud invasion effects. The simulations imply that a time-lapse radar logging is able to extract EM reflection signals from mud invasion front, and the invasion depth and EM velocity can be obtained by a downhole antenna displacement of one source and two receivers. We find that there exists a positive correlation between the estimated invasion depth and permeability curves, and a negative correlation between the estimated velocity and porosity curves. We suggest that borehole radar has potential to estimate permeability and porosity of oil reservoirs, wherein the mud invasion effect is positively utilized. The study demonstrates a potential method of oil reservoir estimation and a novel application of GPR in oil fieldsGreen Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Applied Geophysics and Petrophysic

Modelling of Global Energy Demand in the Transportation Sector: A Country by Country Approach
No full textThis study deals with the modelling of the future global energy demand inthe transportation sector, how and in what extend this could be limited andwhich low carbon fuels and technologies could contribute to the mitigation ofthe energy demand. In the introduction of the current report, the greenhouseeffect, the global warming and the climate change are defined. Then, theactions taken and the agreements made to deal with global warming andclimate change are presented and the need for combating them is highlighted.After the introduction, a literature review is conducted in order to spotthe knowledge gap and formulate the research questions. In the literaturereview, the ICCT’s and IEA’s studies are mainly discussed due to their highquality research and the big amount of published reports. More specifically,their models, scenarios, policies and results are discussed in detail inorder to accurately define the knowledge gap and formulate the researchquestions. Thus, the goal and the main research question of this researchis to answer how could the future global energy demand be mitigated andwhich low carbon fuels and technologies could significantly penetrate intothe transportation sector.In the beginning of this research, the conceptual and the theoreticalframeworks are presented in order to assist with the outline of the thesisand create the theoretical background for the development of the model.Then, in order for the research questions to be answered, a forecasting modelcalculating the transportation future energy demand by country, transportmode, technology and energy carrier throughout the period 2015-2050 is developed.The main features that distinguish this model from models used insimilar studies are the strong focus on the diffusion of low carbon fuels andtechnologies, the use of a different diffusion model (the Bass s-curve) andthe country by country with one-year time increments approach.After the model is verified and validated through comparison with similarstudies and a sensitivity analysis, results are presented for two differentscenarios. The first scenario is called Current Policies scenario and aims toshow a potential pathway of the future global energy demand in the transportationsector that could happen if no more policies are applied after 2020and the second scenario is called Accelerated Policies scenario and its targetis to represent a pathway that could happen if new policies are adopted andstricter implementation is applied.The results of the two scenarios show that it is possible to achieve abending of the energy demand and a diffusion enhancement of low carbonfuels and technologies if new and stricter policies that motivate technologyimprovements and fossil vehicles ban are applied. In particular, the resultsindicate that the implementation of new and stricter policies, which couldlead to efficiency improvements, and to more effective diffusion of low carbonfuels and technologies could achieve reduction of the energy demand after 2029. Moreover, according to the results, electricity is expected to dominate in the transportation sector, while biofuels, hydrogen and ammonia are alsoexpected to be highly used. However, without further policy action, theglobal energy demand is expected to follow a constantly increasing trendin the future while the penetration of low carbon fuels is expected to besignificantly lower.Electrical Engineering | Sustainable Energy Technolog

gprMax: Open source software to simulate electromagnetic wave propagation for Ground Penetrating Radar
No full textAbstractgprMax is open source software that simulates electromagnetic wave propagation, using the Finite-Difference Time-Domain (FDTD) method, for the numerical modelling of Ground Penetrating Radar (GPR). gprMax was originally developed in 1996 when numerical modelling using the FDTD method and, in general, the numerical modelling of GPR were in their infancy. Current computing resources offer the opportunity to build detailed and complex FDTD models of GPR to an extent that was not previously possible. To enable these types of simulations to be more easily realised, and also to facilitate the addition of more advanced features, gprMax has been redeveloped and significantly modernised. The original C-based code has been completely rewritten using a combination of Python and Cython programming languages. Standard and robust file formats have been chosen for geometry and field output files. New advanced modelling features have been added including: an unsplit implementation of higher order Perfectly Matched Layers (PMLs) using a recursive integration approach; diagonally anisotropic materials; dispersive media using multi-pole Debye, Drude or Lorenz expressions; soil modelling using a semi-empirical formulation for dielectric properties and fractals for geometric characteristics; rough surface generation; and the ability to embed complex transducers and targets.Program summaryProgram title: gprMaxCatalogue identifier: AFBG_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AFBG_v1_0.htmlProgram obtainable from: CPC Program Library, Queen’s University, Belfast, N.
