Technologies of gender: Soviet literature and film in the 1920s and 1930s
No full textMy dissertation, “Technologies of Gender: Soviet Literature and Film in the 1920s and 1930s,” examines the vital role technology and machines – both actual and imagined – play in defining the ‘new Soviet man’ and ‘new Soviet woman’ in early Soviet culture. As I argue in my dissertation, the period of the 1920s and 1930s witnesses a radical change in the perception of physicality brought about by new technology. My project elucidates how the rise of technology and technological discourse in Soviet culture remakes the body and reconfigures traditional gender roles, producing a Soviet cyborg (in Donna Haraway’s terms), first male, then female.
In the twenties, in order to combat mortality and render the body perfect, male authors engage in writing about sophisticated technologies based on experimental scientific and medical research (as in Pilnyak’s 1928 A Matter of Death and Platonov’s 1927 The Ethereal Tract). These technocratic utopian imaginings introduce the cyborg that has overcome all mortal constraints, including biological procreation (Platonov). While in the predominantly male avant-garde culture women’s role and access to technology are reduced, I show that in socialist realist texts and films of the 1930s, the reverse takes place: women instead of men now have a privileged relationship to machines. Women artists and workers contest the hyper-masculinist culture and through female cyborgism remap their bodies and consciousness to create their own feminist politics (Shaginian’s 1931 novel The Hydroelectric Plant, Shub’s 1932 film K.Sh.E., and Pasha Angelina’s all-female tractor brigade). The official culture of the thirties refashions itself in the feminine idiom to demonstrate that the never-ending advancement under Stalin exceeds the revolutionary achievements of the 1920s. This obsession leads to the creation of the Soviet heroine of labor, the female cyborg embodied in the image of the woman at the tractor wheel riding into the bright future, the ultimate symbol of transformed Stalinist technocratic society (as in Eisenstein’s General Line (1929), Pyriev’s Tractor Drivers (1939), and Alexandrov’s Bright Path (1940). The project considers both well-known and lesser-known writers/texts and films. At stake is a new way of looking at both literature and cinema of the 1920s-1930s from the point of view of gender technologies and technologies of gender.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Marina Filipovic, accepted the attached license on 2019-07-02 at 14:00.The student, Marina Filipovic, submitted this Dissertation for approval on 2019-07-02 at 14:20.This Dissertation was approved for publication on 2019-07-02 at 17:03.DSpace SAF Submission Ingestion Package generated from Vireo submission #14131 on 2019-11-26 at 13:04:20Made available in DSpace on 2019-11-26T20:49:19Z (GMT).

Infrastructures for data dissemination and in-network storage in location-unaware wireless sensor networks:
No full textFor wireless sensor networks with many location-unaware nodes, we propose mechanisms to organize nodes in an infrastructure of intersecting paths, suitable for efficient data dissemination and event localization. As an underpinning for such an infrastructure, we propose a protocol, dubbed BeSpoken, that steers data transmissions along a straight path called a spoke. The BeSpoken protocol implements a simple, spatially recursive process, where a basic set of control packets and a data packet are exchanged repeatedly among daisy-chained relays that constitute the spoke. Hence, a data packet originated by the first relay makes a forward progress in the direction of the spoke. Despite the
simplicity of the protocol engine, modeling the spoke process is a significant challenge. The protocol directs data transmissions by randomly selecting relays to retransmit data packets from crescent-shaped areas along the spoke axis. The resulting random walk of the spoke hop sequence may be modeled as a two dimensional Markov process. Analysis of this model results in design rules for protocol parameters that minimize energy consumption while ensuring that spokes propagate far enough and have a limited wobble with respect to the spoke axis. In addition, adaptive mechanisms are proposed that increase the propagation distance under the same energy per spoke hop.
Finally we show how the spokes serve as the building block of a web-like infrastructure that can be used for data source localization and efficient data search and dissemination. In particular, we demonstrate how to increase data availability and persistence through the application of distributed coding techniques over concentric circular subnetworks forming the infrastructure. We study decentralized, Fountain, and network-coding based strategies for facilitating data collection, which rely on the stochastic diversity of data
storage. The goal is to allow for a reduced delay
collection by a data collector who accesses the circular network at a random position and random time. Data dissemination is performed by a set of relays which form a circular route to exchange source packets. The storage nodes within the transmission range of the
route's relays linearly combine and store overheard relay transmissions using random decentralized strategies. An intelligent data collector first collects a minimum set of coded packets from a subset of storage nodes in its proximity, which might be sufficient
for recovering the original packets and, by using a message-passing decoder, attempts recovering all original source packets from this set. Whenever the decoder stalls, a source packet which restarts decoding is polled/doped from its original source node. The random-walk-based analysis of the decoding/doping process furnishes the collection delay analysis with a prediction on the number of required doped packets. The number of doped packets can be
surprisingly small when employed with an Ideal Soliton code degree distribution and, hence, the doping data collection strategy may have the least collection delay when the density of source nodes is sufficiently large. We also demonstrate that network coding makes
dissemination more efficient at the expense of a larger collection delay. Not surprisingly, a circular network allows for a significantly more (analytically and otherwise) tractable strategies relative to a network whose model is a random geometric graph.Ph.D.Includes bibliographical references (p. 124-128)by Silvija Kokalj-Filipovi
The effects of extrinsic and intrinsic rewards on partners' likelihood to refer
No full textIn dieser Masterarbeit wird die Bedeutung von Belohnungen im Empfehlungsmarketing in Business-to-Business (B2B) Beziehungen thematisiert. Empfehlungsmarketing in B2B-Beziehungen wird im Gegensatz zum traditionellen Marketing dazu verwendet, um mittels des Einflusses bestehender Partner neue Kunden zu gewinnen. Im Gegensatz zu früheren Studien unterscheidet diese Arbeit zwei Arten von Belohnungen, die für das Empfehlen angeboten werden: die intrinsischen und die extrinsischen. Intrinsische Belohnungen sind immaterieller, psychologischer Natur, während extrinsische Belohnungen sichtbar und materieller Natur sind. Der Autor untersucht zusätzlich den Moderationseffekt von Marken- und Bindungsstärke auf die Empfehlungswahrscheinlichkeit des Partners. Aufgrund fehlender Forschungsergebnisse im Bereich der Umsetzung von Empfehlungsmarketing in Österreich, verwendet der Autor eine Online-Umfrage, um Daten von Einkaufsabteilungen in B2B-Unternehmen in Österreich zu erheben. Ein wesentliches Resultat dieser Arbeit ist, dass Belohnungen jeglicher Art von Beziehung die Empfehlungswahrscheinlichkeit erhöhen, was auch die Austauschtheorie unterstützt. Weiters ist zu berichten, dass die Empfehlungswahrscheinlichkeit allgemein steigt. Insbesondere sind die extrinsischen Belohnungen für die schwächeren Beziehungen mehr relevant als für die stärkeren, wobei die intrinsischen Belohnungen die Empfehlungswahrscheinlichkeit eher in stärkeren als in schwächeren Beziehungen erhöhen. Anders ausgedrückt: Für langfristige Partner ist eine nicht monetäre Belohnung von größerem Wert, während für Partner, die von Zeit zu Zeit miteinander arbeiten, die monetäre Auszeichnung von Bedeutung ist. Hingegen zeigt sich kein relevanter Effekt, wenn der Lieferant über eine hohe Markenbekanntheit und einen etablierten Markenverband verfügt, die Empfehlungswahrscheinlichkeit des Partners bleibt dabei gleich und der Effekt der beiden Arten von Belohnungen wird weder stärker noch geringer.In this masters thesis the importance of rewards in referral marketing in Business-to-Business (B2B) relationships is introduced. Referral marketing in B2B relationships is used in order to acquire new customers because of the influence of existing partners, rather than through traditional marketing. In contrast to previous researches, this one distinguishes between two types of rewards offered for recommending, intrinsic and extrinsic. Intrinsic rewards are more intangible and psychological and extrinsic rewards are visible and tangible. As well, the author investigates the moderating effect of brand and tie strength on partners referral likelihood. Given the lack of existing research in the area of implementing referral marketing in Austria, the author used an online survey for collecting data from purchasing departments in B2B firms. One overall contribution out of this masters thesis is that rewards increases referral likelihood in every relationship, which supports the exchange theory. More specifically, the extrinsic rewards are more important for weaker rather than for stronger ties and the intrinsic rewards are more increasing the willingness to recommend in stronger than in weaker relationships. To put it differently, for long term partners a non-monetary reward has more value, while for partners which corporate from time to time with each other the monetary award matters. Additionally, suppliers brand in fact does not have any impact on this exchange process. More specifically, there is no relevant effect if the supplier firm is having high brand awareness and a well-established brand association, the partners referral likelihood will remain the same and will not increase nor lower the effect of the two types of a rewards.Sanda Filipovic, BScZusammenfassungen in Deutsch und EnglischMasterarbeit Karl-Franzens-Universität Graz 2018 D 1107

Building Community: a Critical Appraisal of Toronto’s Tower Renewal Program
No full textHigh-rise housing is a global phenomenon. In Toronto, the sheer number of tower blocks and declining conditions within them has pointed to the importance of redeveloping high-rises in order to improve their current performative capacity and secure their use for future generations. In addition, improving the public realm and social infrastructure in these communities has emerged as an important component of the redevelopment approach. Looking at the City of Toronto’s Tower Renewal program, the paper critically evaluates its environmental, economic and social/cultural objectives using Tower Renewal documents, local case studies and relevant literature. Analysis of program specifics leads to a greater understanding of the potential and prospects, as well as areas for improvement in tower redevelopment programs, the roles and collaborative relationships between participating parties, and how placemaking processes are and can be pursued and accommodated in redevelopment programs
Ideological implications of 'Traces' by Vukasin Filipovic
No full textThe aim of this paper is to highlight the devastating impact of totalitarian regimes on artistic creativity. Novel 'Traces' is reviewed in the context of the post World War II period of communist revolutionary inspiration in former Yugoslavia. Novel, embraced as the most suitable literary form, was completely in the service of the system. Tendentious ideological implications of 'Traces' overshadowed the layers of authentic testimonies about life in Kosovo plain in the novel. Despite the undoubted influence of revolutionary and ideological motivation, it is noted that the author attempts to overcome this influence to some extent
Design and implementation of a sink term for the thermal energy equation pertaining to tranpiration from vegetation
No full textBachelor project part of the double degree bachelor in mathematics and physics. Calculating the temperature field in the presence of vegetation has many practical applications, such as the study of urban heat islands, but much research still needs to be done in this field of study. The objective of this paper is to describe and test a model, which takes into account the cooling effect of transpiration of vegetation. To this end, first, the velocity field is modelled by the Reynolds averaged Navier Stokes equations, with the turbulent behaviour represented by the k-ε turbulence model. The model of Katul et al. is used to account for the vegetation dependence of the air flow. Subsequently, the Reynolds averaged thermal energy equation and the simple gradient diffusion hypothesis are used to describe the temperature effects. In order to account for the cooling from transpiration of vegetation a sink term of the Reynolds averaged thermal energy equation was derived. In this derivation dimensional analysis was performed on the cooling power, approximated by Blocken et al. and Rahman et al., and other relevant properties. The finite volume method is used to discretise the differential equations. In this paper the simulations have all been performed within the same domain. This domain is defined by Liang and is a box shaped area, in which a forest is planted of non-uniform leaf area density. The first two simulations test whether the model without transpiration effects produces feasible results. Measurement data of the streamwise velocity showed good agreement and measurement data of the turbulent kinetic energy, which is a measure for the turbulence, also showed reasonable agreement. The results showed that, even without the thermal sink term active yet, the temperature field is affected significantly by the presence of vegetation. The following two simulations test the performance of the numerical simulations. The reference grid was changed to contain double the amount of control volumes and half the amount of control volumes and the results conclude that both the velocity and the temperature are grid independent. The turbulent kinetic energy is slightly dependent on the chosen grid. The values of most properties on the faces of the control volumes were approximated by the central differencing scheme, but for the convective terms the upwind differencing scheme was used. The values of the convective terms were also approximated with the quadratic differencing scheme. These schemes show similar results in the middle of the domain, but at the boundary the quadratic differencing scheme shows some fluctuations which are not realistic. Further research is needed to explain this phenomenon. In the last simulation the thermal sink effects resulting from transpiration are implemented. Results show that the area in front of the forest is not affected by the sink and that the region inside the forest is most affected by the its implementation. The maximum temperature difference, with respect to the results without transpiration effects, was about 7.1 °C, which shows that the effect of the sink is extensive. The results of this simulation seem intuitively correct, however, it would be an excellent subject for future research to test these results against measurement data. Another interesting subject for future research would be to experiment with different expressions of the thermal sink term to see how this influences the solution.Electrical Engineering, Mathematics and Computer ScienceApplied Physic
A sliding mode based controller for no inertia islanded microgrids
No full textThe papers presents a new concept for controlling voltage and frequency in islanded microgrids composed by a Battery Energy Storage System (BESS) and Photo-Voltaic (PV) Units. The proposed approach is totally decentralized as each source is equipped with a purely local controller and no communication infrastructure is needed. Moreover, a centralized secondary control is not required as the developed local controllers are able to nullify both frequency and voltage errors. Finally, the physical constraints related to BESS power and State Of Charge (SOC) limits are accounted and some theoretical hints are provided to justify why the frequency can be used as a triggering signal for the controllers to switch among the different operation modes even in absence of synchronous machines directly connected to the grid
Exact Analytical Solutions for Modelling the Speed-Time Characteristics of Direct-Start Induction Machines under Various Operational Conditions on Ships: Review and Experimental Validation
No full textInduction machines (IMs) are crucial to driving auxiliary machinery and devices of ships, such as pumps, fans, winches, and elevators, which are essential for maintaining the operational functions of a ship and are characterised by various types of loads. This is of critical importance because high surges of starting current can cause instabilities and fluctuations in a ship’s power system, directly affecting the safety and efficiency of ship operations. This paper provides a comprehensive review of analytical expressions for modelling the start-up time of directly started IMs under different ship operational conditions (no-load, linear load, fan load, and gravitational load). Validation of the analytical models was performed by comparing the speed-time characteristics obtained from the experimental measurements with the corresponding ones obtained by simulations in a MATLAB Simulink environment. The observed 1.5 kW IM reached a steady state for 0.1356 seconds when driving the load with a fan characteristic. However, when subjected to linear and gravitational loads, the IM requires longer times to reach a steady state - 0.1400 and 0.1606 seconds, respectively. The results of the simulations and experimental tests highly corresponded with the analytical predictions, confirming the reliability and practical applicability of the analytical models
