Dentate granule and mossy cells exhibit distinct spatiotemporal responses to local change in a one-dimensional landscape of visual-tactile cues
No full textThe dentate gyrus (DG) is critical for detecting changes in environments; however, how granule cells (GCs) and mossy cells (MCs), the two excitatory cell types of the DG, respond to small changes in the object layout is unclear. Here, we recorded GCs and MCs, identified by spike feature and optogenetic tagging, as mice ran on a treadmill belt enriched with visual-tactile cues. We observed that fixing a new cue on the belt induced a reconfiguration of GC and MC spatial representations via the emergence, extinction and rate alteration of firing fields. For both GCs and MCs, the response was maximal near the cue and spread over the entire belt. However, compared to the GC response, the MC response was stronger and more immediate, peaked at a slightly earlier belt position, and exhibited a transient component reminiscent of neuromodulatory activity. A competitive neural network model reproduced the GC response contingent on both the introduction of new object-vector inputs and the reconfiguration of MC activity, the former being critical for spreading the GC response in locations distant from the cue. These findings suggest that GCs operate as a competitive network and that MCs precede GCs in detecting changes and help expand the range of GC pattern separation.
Towards uncertainty in micro-grids: planning, control and investment
No full textThe advent of micro-grids and their potential participation in the wholesale market makes the development of new business models necessary. It is anticipated that the future wholesale market for electricity and its ancillary services will include the existing major players as well as microgrids, which will act both as buyers and sellers. The wholesale market will shift more towards a distributed system with the centers of gravity dynamically changing depending on how the smaller micro-grids play out their supply and demand and also how the market aggregation takes place. Having the obligation to fully satisfy its demand at each point of time, any shortage in available power supply within the micro-grid will lead to the purchase of electricity from the macro-grid at spot market price. The sources of variability rising from the forecast of renewable energy resources and electricity demand, would introduce uncertainty in making decisions at planning layer. Also, a micro-grid may fail to honor its contractual obligations to supply to the market due to these volatilities.To optimize the planning and operation of micro-grids, it is important for the planner and controller to take into account uncertainties inherent to the microgrid and the overall supply and demand network, including the energy market place. With high capital costs involved in building a micro-grid, sequential investment strategies, which promote gradual increase in capacity of generation, are needed. This work aims to develop a set of models and tools that address the optimal decision-making processes involved in both operation and investment in micro-grids. These models account for short-term operational and long-term investment uncertainties in decision making and adopt the following analytics: Two-stage stochastic programming and certainty equivalent models to obtain optimal decisions for day-ahead planning in micro-grid’s operation; Contingent claim analysis and Monte Carlo simulation to examine the value in delaying the investment due to uncertainty around the investment; Capital budget planning model along with Monte Carlo stochastic scenario generation to derive the optimal investment decisions for micro-grid’s portfolio considering its optimal operation under uncertainty.M.S.Includes bibliographical referencesby Farnaz Farza
Interaction of microwave filaments and blunt body in supersonic flow
No full textRecent experiments have demonstrated the capability of pulsed microwave energy deposition for drag reduction in supersonic flows. The principal mechanism of this phenomenon is the interaction of the hot filaments generated by the microwave energy pulse with the shock system formed by the aerodynamic body. In this work, the filament is modeled as a thin fluid region of high temperature. The interaction of the filament(s) with a cylindrical body at Mach number 1.89 is examined using the unsteady Euler equations. Two filament structures are considered, namely, 1) an infinitely long filament, and 2) a periodic train of finite filaments (at different frequencies). The development of the flow structure during the interaction is investigated. Furthermore, the drag reduction effectiveness and efficiency of the process of the interaction of the microwave filament(s) with the cylindrical shock layer for each case are studied.M.S.Includes bibliographical references (p. 71-73)

Beyond and Behind Platforms and Algorithms: Exploring the Lived Experiences of Gig Workers
No full textWhile the literature on gig work is expanding rapidly, many are the issues that need to be answered in order to fully understand the lived experiences of gig workers and illuminate the dynamics of gig work. Despite it is widely recognized that gig workers constitute an heterogenous workforce, for instance, seminal works have focused on finding similarities among gig workers across platforms, while the mechanisms behind different gig workers’ behaviors and perceptions are still widely obscure. Moreover, most of the literature focuses on what gig workers do individually on platforms, but not – or only cursorily – on how these workers manage the interplay between their online and offline activities. Specifically, comprehending how the online dimensions of work blur or integrate with offline aspects of gig workers’ lives – such as family condition or family needs, the presence of alternative, offline jobs, the cultural context of the community and country of origin – is of significant importance. This symposium addresses these issues by examining what happens behind and beyond platforms, and by presenting four papers looking at different gig workers’ experiences and different forms of interplay between online and offline aspects of gig work.

RAHIMZADEHASL, Farnaz. Comparactive Thematic Analysis on Aytul Akal and Susan Taghdis's Stories İn Terms Of Children's Literature. Master Thesis, Ankara, 2019.
Turks and Iranians, two great members of the same culture and civilization circle, have been interacting in many ways throughout their long and deep rooted history, it is obvious that the two civilizations are too close,To date, scientific research on these two neighboring countries has not reached the level they deserve in historical, sociological, political and military fields and finally in the field of literature which constitutes our main subject.The comparative literature studies,which must be done and which constitute the backbone of our thesis, are vital to determine the common values and facts of the two communities,especially in the determination of shared history and to understand how they take part in the construction of their future. In view of the functions of literature to influence, change, and direct societies, it is no doubt that the above-mentioned need removal function can be done most effectively or through literature. Children's literature, which is one of the controversial areas of literature, provides sufficient materials for the cultural comparisons mentioned above. The main topic of our thesis is the examination of the stories of the some works of Aytül Akal, a Turkish author translated into Persian within the scope of the TEDA program, and of Iranian author Susan Taghdis,translated into Turkish within the scope of the Top program.The aim of the thesis is to compare the stories of the two authors; their take on children's literature from a thematic review on these two samples ,drawing a general framework of the subjects of comparative literature and children's literature.In the same period, their understanding of art and the lives of these two women writers, who have witnessed similar cultural and sociological changes in their societies, and who are the leading names in children's literature in their respective countries.

RAHIMZADEHASL, Farnaz. Aytül Akal ve Susan Taghdis 'in Çocuk Hikâyeleri Üzerine Karşılaştırmalı Tematik Bir İnceleme. Yüksek Lisans Tezi. Ankara, 2019.
Aynı kültür ve medeniyet dairesinin iki büyük mensubu olan Türkler ile İranlılar uzun ve köklü tarihleri boyunca birçok açıdan etkileşim içinde olmuşlardır. Bu iki ülkenin bin yılı aşkın bir süredir komşu olmaları hasebiyle ortak medeniyet paydalarının diğer milletlere nazaran çok daha fazla olduğu açıkça ortadadır. Bugüne kadar tarihî, sosyolojik, siyasi ve askerî alanlarda ve nihayet ana konumuzu teşkil eden edebiyat alanında bu iki komşu ülke üzerinde yapılan bilimsel araştırmalar hak ettikleri düzeye ulaşmamıştır. Mutlaka yapılması gereken ve bizim de tezimizin omurgasını oluşturan karşılaştırmalı edebiyat çalışmaları iki milletin birbirini daha yakından tanıması, ortak tarihlerine yönelmesi ve geleceklerinin inşasında nasıl tavır alacaklarının tayininde özellikle iki toplumun hangi ortak değer ve olgulara sahip olduklarının tespit edilebilmesinde hayati önem taşımaktadır. Edebiyatın toplumları etkileme, değiştirme ve yönlendirme işlevleri göz önüne alındığında yukarıda bahsedilen ihtiyacı giderme fonksiyonunun en çok ya da en etkili şekilde edebiyat aracılığıyla yapılabileceği kuşkusuzdur. Edebiyatın tartışmalı alanlarından biri olan çocuk edebiyatı da yukarıda bahsedilen kültürel karşılaştırılmaların yapılabilmesi açısından yeterli malzemeyi sunmaktadır. Bu itibarla tezimizin ana konusunu, TEDA programı kapsamında bazı eserleri Farsçaya çevrilen Türk yazarı Aytül Akal ile TOP programı kapsamında bazı eserleri Türkçeye çevrilen İranlı yazar Susan Taghdis'in hikâyelerinin incelenmesi oluşturmaktadır. Tezin amacı, iki yazarın hikâyelerini karşılaştırmak; yazarların eserlerinden hareketle çocuk edebiyatına yükledikleri işlevi tespit edip kıyaslamak; aynı zamanda Türkiye ve İran sahası çocuk edebiyatını bu iki örnek üzerinden tematik açıdan bir incelemeye/değerlendirmeye tabi tutmaktır. Ayrıca konunun daha iyi ortaya konması adına karşılaştırmalı edebiyat ve çocuk edebiyatı konularının genel bir çerçevesi

çizilerek literatürleri hakkında bilgi verilecektir. Aynı dönemde yaşayan, Türk ve İran toplumlarının benzer kültürel ve sosyolojik değişimlerine şahit olan, ülkelerinin çocuk edebiyatı alanında önde gelen isimlerinden olan bu iki kadın yazarın hayatları, sanat anlayışları ve kendi ülkelerinin modern edebiyatındaki yerleri de tespit edilmeye çalışılacaktır.

Travelling microwave reactor design
No full textIn this work, the doctoral thesis of G.S.J. Sturm on microwave reactors was continued. Microwave reactors are developed, because they have potential to increase safety and economically reduce waste. This work focused on microwaves and chemical processes, instead of just heating water, by designing a travelling microwave reactor for non-oxidative methane dehydroaromatization.The travelling microwave reactor was designed using a structured approach. First, the objective was set to an economical conversion to aromatics of otherwise flared methane. Therefore, a successfully designed reactor is able to reduce the CO2 emissions and make many other reactions economical. Secondly, twenty-one challenges for microwave reactors were found using check-lists and a self-developed phenomena exploration method. This method was used to find unknown challenges on the intersection of established engineering fields. Then sub-solutions solving these challenges were extracted from existing reactors and reactor concepts. Finally, a few sub-solutions were selected and forced to work together to obtain the designed reactor.The designed reactor consists of a high performance coated asymmetric annular monolith in an inert container with narrowing conductors in axial direction and an anisotropic porous media. The achieved production volume is three orders of magnitude larger than of a mono-mode microwave reactor at same operation frequency. The designed reactor is capable of obtaining another five orders of magnitude by increasing the temperature up to 1500K, pressure up to 50 atm, catalyst activity with at least two orders of magnitude and lowering the operating frequency. However, only four orders of magnitude were reached, because the designed reactor hit a flow limit.The designed reactor with the three plus four order of magnitude improvement is not yet economical feasible. More advanced designs such as the spiralling narrowing rectangular microwave reactor might be. Furthermore, the designed reactor could become economically feasible in case of a more valuable product. Eventually, this work revealed some unsolved problems and opportunities of microwave reactors as well as information gaps. Moreover, it brought microwave reactors closer to industrial application.<br/
Analysis and Detection of Neural Synchrony in the Prefrontal Cortex
No full textSignal Analysis techniques are routinely used in Neuroscience to interpret raw signals harvested from the Nervous System. From a simple Fourier analysis to more complicated methods such as multiresolution wavelet analysis, such techniques must be used for signal manipulation in order to reach informed conclusions on the measurements taking place.In neuroscientific research, it is common practice to scan a neural recording manually to label the areas of the signal that are relevant to the research at hand. This can, obviously, be very time-consuming for the researchers. What is more, this method can prove imperfect, seeing as two different researchers can disagree on the labeling of the data.In every experiment, signal epochs are isolated because they stand out from the rest of the recording due to a special characteristic, which is, in the previous case, visible with the unaided eye. In signal processing terms, this means that the signal displays specific spectrotemporal characteristics during these epochs. Thus, these characteristics can be isolated, quantified and studied independently, while a detection algorithm can be developed so that the detection and labeling of the significant signal epochs can be carried out automatically.In this project, the spontaneous activity of the neurons in the Prefrontal Cortex was analyzed in relation to neural synchrony, using time-varying ARModels. It was concluded that the signal epochs of neural synchrony display common characteristics besides being visually similar. This allowed the isolation of the synchrony epochs based on model parameters.However, the training of the models is very computationally intensive, so a detection algorithm was developed, based on a matched filter which made use of one of the isolated epochs as a template. The detection scheme was then validated using a recording harvested during electrical stimulation of the deep brain, evaluating the quality of the scheme was evaluated.Finally, the detection scheme was applied to stimulation recordings to study the electrical behavior of the Prefrontal Cortex during electrical stimulation of deep brain structures.Biomedical Engineerin
Exploring Impacts of Project Overload on Creativity : An Agent-Based Modeling Approach
No full textProject overload is an unpleasant phenomenon which is happening for employees inside those organizations trying to make the most efficient use of their resources. AE project inside VolvoCE (VCE) is an Advanced Engineering project eager to be innovative suffering from project overload. This research aims to help VCE to move towards creative organizational climate. To do this, the author used the Agent-based modeling (ABM) approach to examine the current reality of VCE and AE projects, where the opportunities and challenges for reducing the risk of project overload and moving towards innovation were identified. The results of this research allowed the researcher to define the gaps inside AE project and create a list of some recommendations. From these results: project overload can damage the employees’ focus and bring psychological stress reactions; Creative actions are less likely to be the result of a team with high level of project. On the other hand, motivation on proper challenging goal is more likely to help individual to alleviate the negative aspects of low level of project overload
