Focused and General science parks: a study of New Technology Based Firms within Life-sciences in Sweden
No full textNew Technology-Based Firms (NTBFs) contribute greatly to the development and construction of their nations‟ economies. Therefore their creation, survival and growth have become a major focus for policy. Science parks as actors within regional innovation systems can be suitable tools to carry out this objective. This paper investigated whether the type of science park has any effect on performance of NTBFs. To this end science parks were categorized as focused –hosting firms from a single industry- and general –more than one industry. A comparative study based on second hand data collection was performed on Swedish science parks working within Life-sciences. The results revealed that focused science parks are better stimulants of employment creation and that their residents enjoy higher rates of sales growth. The author recommends that further categorization of science parks leads to better recognition and utilization of their potential
Fielding Peter Carey: economy, archive, celebrity
No full text© 2018 Dr. Keyvan AllahyariThis thesis accounts for a method of reading Carey’s fiction as works of national literature in the minor register (colonial, peripheral, small) which refract a sense of the possibility of circulation in transnational literary markets. The publication of Carey’s debut work, The Fat Man in History, by the University of Queensland Press in 1974 coincided with the termination of The Traditional Markets Agreement, which resulted in assisting American publishers to roam more freely in the Australian literary market. Drawing on Pierre Bourdieu’s concepts of the literary field, capital, and habitus, my thesis starts by examining the publication of The Fat Man as a microevent to better understand the macroevent of Carey’s position-taking in the transnational marketplace. The mid-1970s shifted Carey’s position in the field and established a trajectory through which he accumulated significant cultural and economic capital in the following decades. This method interrogates Carey’s rising visibility in relation to the construction of a new status for the postcolonial authors and the possibilities of the global publishing industry since the 1960s throughout to the present moment, including the politics of literary prizes and literary festivals, the rise of literary agents, the commodification of literary archives, and the merging of conglomerate publishing houses.
Carey’s fiction exhibits the anxieties of an Australian author ensnared in neoliberal systems of literary production and distribution, a free market economy biased against national territories (such as Australia) on the periphery of a world republic of letters. Drawing on the sociological paradigm of Pierre Bourdieu, this thesis asks how, and to what extent, can we think of Carey’s fiction and his writerly persona as cultural objects circulating within the global literary marketplace? How does his fiction refract the global forces that produce and distribute his books and celebrity? And what is the relationship between Carey’s stories and the literary marketplace, between the making of his books and the reading of them? Thus, my study offers a lateral examination of two interrelated aspects of Carey’s fiction. On the one hand, it captures a continuum of Australian and transnational practices of literary distinction and advancement that governed the critical and financial success of Carey’s fiction; on the other, it produces insights into the structural homologies between the literary spaces that Carey inhabits and those of his Australian characters confined to minor systems of cultural production and consumption

No full textA framework for measuring the supply chain's agility of mass construction industry in Iran
No full textImpotent planning system in house providing process is the result of inadequate housing management system in theoretical, empirical, and operational fields. In addition, Mass Construction industry in Iran confronts with other problems such as instability in raw material prices, unsteadiness in production and investment laws and regulations, frailty of transportation infrastructure, international sanctions and etc. Furthermore, customers’ needs, lower costs, and greater customizations lead mass producing to search for new solutions and novel producing system. Agility is offered as a strategy to enable Mass Construction associations to be maintained in the competition of constantly changing market in Iran. In such a market, previous approaches lose their capabilities in supply chain. Thus to achieve agility by Mass Construction association is the chief aim of this study. This study is descriptive-analytic and can be identified as developmental –functional considering its target. After surveying previous research literature and using experts’ opinions, we investigated final agile sub criteria of supply chain and then we used interpretive- structural modeling approach to determine the relation among sub criteria and to offer an agile supply chain model. Surveying research literature and experts’ opinions lead us to identify 8 criteria (society, government, financial, information technology, market, partnership, quality and technology) and also 22 sub criteria for supply chain’s agility. Then the results were analyzed through interpretive-structural approach and relation of criteria and sub criteria and their consequence were achieved. These relations showed that government and infrastructure investment, culture, regulations and responses to social and environmental issues are the basis of agility in mass housing productions’ supply chain. This model helps supply chain managers to have strategic planning to enhance agility in supply chain and find effective sub criteria and criteria to invest on
From Corpus to Bio-Text; Peter Carey’s Archives as Literary Networks
No full textCarey's archives add a new facet to Carey’s public image as an Australian author. In principle, the archive is directed at posterity, defying the ephemeral nature of “personality” pieces about the writer, a phenomenon that Grahame Turner has discussed in terms of Carey’s active participation in accumulating recognition amounting to the construction of Carey’s author-persona as a “national celebrity” (136). My interest in this essay is to explore the ways that Carey’s archives contribute to our understanding of productive mechanisms of his celebrity. In doing so, I theorize the formation and the significance of Carey’s archives both as texts and objects. I argue that the archiving of Carey is energized by a collective investment by a body of cultural participants who have a stake in promoting the now ‘globalised’ author. This has ultimately resulted in relocalising the ‘corpus’ of the New York based writer back in Australia, and particularly in the State Library of Victoria in Melbourne. This archive has been regularly updated alongside Carey’s growing oeuvre. In this parallel literary space, however, Carey’s cultural agency continues to manipulate his public persona.
Digital Signal Processing for a Wireless ECG Device: Wireless Electrocardiogram (WiECG)
No full textThe goal of the WiECG project is to create a prototype device that makes it possible to perform a 12-lead ECG measurement on patients without wires from the patient to a monitor. The solution consists of a transmitter and receiver, one of which is close or on the patients body and the other is connected to a monitor.This thesis describes the design and implementation of a subsystem of the prototype device that performs digitization, digital processing and reconstruction of the measured 12-lead ECG signal. This concerns converting nine 0 to 3.3V analog signals to the digital domain by using Analog-to-Digital converters, real-time filtering of nine signals with multiple digital IIR filters and reconstructing nine digital signals to the analog domain using Digital-to-Analog converters. Furthermore, component selection, design decisions and the implementation process will be detailed in this document.The subsystem proposed in this paper is able to successfully sample, efficiently filter and reconstruct nine signals in real time. Recommendations on improving the implementation to better adhere to the lower power requirements for a longer battery life are provided as future research prospects.Computer Engineerin

Traffic-responsive signals combined with perimeter control: investigating the benefits
No full textEmpirical and research evidence suggests that traffic-responsive signal control strategies are generally not as efficient in over-saturated traffic conditions characterized by queue spillbacks. Recent studies on (MFD/NFD) have identified a destabilizing gridlock process that arises in congested networks which precludes efficient operation. The MFD has also been used to develop urban traffic control solutions (e.g. perimeter or gating control) to avoid congestion. The purpose of this paper is to explore the benefits of combining gating with locally adaptive traffic signals through micro-simulation of the Chania, Greece traffic network. Two adaptive traffic signal strategies are considered with the perimeter control strategy. The results of the combined gating/adaptive signal control scheme are compared to gating under fixed traffic signals and the implementation of adaptive signals only. The convincing outcome of this simulation study motivates the real-field implementation of gating/perimeter control in the cities, without even changing the existing adaptive control strategies.Green 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.Transport and Plannin
Capacity Results for Interference Networks and Nested Cut-Set Bound
No full textIn this thesis, a full characterization of the sum-rate capacity for degraded interference networks with any number of transmitters, any number of receivers, and any possible distribution of messages among transmitters and receivers is established. It is proved that a successive decoding scheme is sum-rate optimal for these networks. Moreover, it is shown that the transmission of only a certain subset of messages is sufficient to achieve the sum-rate capacity for such networks. Algorithms are presented to determine this subset of messages explicitly. The sum-rate expression for the degraded networks is then used to derive a unified outer bound on the sum-rate capacity of arbitrary (non-degraded) interference networks. Several variations of degraded networks are identified for which the derived outer bound is sum-rate optimal. Specifically, noisy interference regimes are derived for certain classes of multi-user/multi-message large interference networks. Also, network scenarios are identified where the incorporation of both successive decoding and treating interference as noise achieves their sum-rate capacity.
Next, by taking insight from the results for degraded networks, an extension to the standard cut-set bound for general communication networks is presented which is referred to as nested cut-set bound. This bound is derived by applying a series of cuts in a nested configuration to the network first and then bounding the information rate that flows through the cuts. The key idea for bounding step is indeed to impose a degraded arrangement among the receivers corresponding to the cuts. Therefore, the bound is in fact a generalization of the outer bound for interference networks: here cooperative relaying nodes are introduced into the problem as well but the proof style for the derivation of the outer bound remains the same. The nested cut-set bound, which uniformly holds for all general communication networks of arbitrary large sizes where any subset of nodes may cooperatively communicate to any other subset of them, is indeed tighter than the cut-set bound for networks with more than one receiver. Moreover, it includes the generalized cut-set bound for deterministic networks reported by Shomorony and Avestimehr which was originally a special case of the outer bound established for the interference networks by the author (2012).
Finally, capacity bounds for the two-user interference channel with cooperative receivers via conferencing links of finite capacities are investigated. The capacity results known for this communication scenario are limited to a very few special cases of the one-sided channel. One of the major challenges in analyzing such cooperative networks is how to establish efficient capacity outer
iv
bounds for them. In this thesis, by applying new techniques, novel capacity outer bounds are presented for the interference channels with conferencing users. Using the outer bounds, several new capacity results are proved for interesting channels with unidirectional cooperation in strong and mixed interference regimes. A fact is that the conferencing link (between receivers) may be utilized to provide one receiver with information about its corresponding signal or its non-corresponding signal (interference signal). As an interesting consequence, it is demonstrated that both strategies can be helpful to achieve the capacity of the channel. Lastly, for the case of Gaussian interference channel with conferencing receivers, it is argued that our outer bound is strictly tighter than the previous one derived by Wang and Tse
