402	Matematické metody segmentace obrazu pro dálkový průzkum Země / Mathematical Methods of Image Segmentation for Remote Sensing Applications Novotný, Jan January 2015 (has links) Segmentation of an image into individual tree crowns is a key step in the processing of remotely sensed data for forestry practice. The doctoral thesis gives a broad overview of this topic. It comprehends theoretical context from mathematical point of view and defines basic terms from airborne imaging and laser scanning. Mathematical methods of tree detection are focused on a robust adaptation to the actual conditions in a region of interest. A novel approach of crown area delineation is introduced, it combines a seeded region growing technique with an active contour as a crown boundary representation. The parametrisation of all algorithms is analysed in a practical half of the thesis and more application-oriented issues are mentioned. Executable computer programs are attached.
403	Macrocyclic chemistry: Part I - Characterization of a mixed-valence di-iron complex and synthesis of a new poly-iron complex. Part II - Synthesis, characterization of new diphosphoester macrocyclic polyethers Hoang, Son Xuan 01 January 2011 (has links) (PDF) Our research involved two projects: Crown Aza and Crown ether. Crown Aza are compounds that have nitrogens as the hetero-atoms in the macrocycle. In the first aim, the 1 H NMR spectrum of strongly-coupled di-iron complexes shows 5 different conformations, but is unable to identify these conformers. Calculation using Density Functional Theory (DFT) were performed to attempt to quantify these conformers to correlate with the experimental NMR data. The second aim of this study was to utilize the carbonyl functional group of the macrocycles to couple the iron complexes to obtain tetramers or higher oligomers. Visible spectra of the selective reduction of iron mono-keto-macrocycles with boron trifluoride and triethylsilane showed a coupling reaction to form a di-iron complex. A mixture of iron mono-keto-macrocycic with iron diketo-dimacrocycle showed a new species with an intense NIR absorption at 1010 nm. This intense band at 1010 nm is extremely rare in transition metal compounds and is of potential interest in photodynamic therapy. This indicates a new species is formed with a very low energy gap between the ground and excited states. Our second interest is in ionizable crown ethers that have many potential applications from environmental to medical. These macrocyclic poly-ethers contain phosphorous and oxygen atoms which produce a charged moiety in the ring to form a neutral complex with our targeted ions. They are significantly different from all ionizable cyclic poly-ethers in the literature. They vary in ring size from 16-crown-6 to 22-crown-8 using ethylene or propylene linkages between the oxygen atoms. Theoretical calculations revealed these ionizable crown ethers can accommodate ions from 2.6 angstroms to 4.2 angstroms in diameter. Strontium 90 ( 90 Sr 2+ ) is a radioactive product ion from nuclear fission reactions. The Phosphorous containing macrocyclic poly-ether with 2 charges could form complexes with Strontium and are possible candidates for clean-up agents of radioactive materials. The synthesis of ionizable crown ethers is discussed.

405	Cash is [no longer] king: is an e-krona the answer? : - a de lege ferenda investigation of the Swedish Riksbank's issuing mandate and other legal callenges in relation to economic effects on the payment market Imamovic, Arnela January 2019 (has links) For the past decades, the Swedish public’s payment habits have changed, where the majority of the public has abandoned the old way of making payments, using cash, and instead opted for more modern payment solutions, digital money. The difference between cash and digital money is that cash is physical and only issued by the Riksbank, whereas digital money is created by and stored on accounts at commercial banks. The question of what role the state should have on the payment market is an important point of discussion. But it is not categorically a new question; the Swedish government is tackling essentially the same problem today as it has been doing many times before. Today’s problem is to some extent however manifested in a different way. During the 20th century, discussions were held whether or not the Riksbank should have the exclusive right to issue banknotes. It was considered unnecessary, inappropriate and dangerous. The idea that the Riksbank could cover the entire economy’s need for banknotes was, according to the commercial banks, unreasonable. Nonetheless, in 1904 the exclusive right became fait accompli; the government intervened and gave the Riksbank the banknote monopoly. We are now finding ourselves facing a similar situation, where there is a difference of opinion regarding the Riksbank’s role on the payment market. It is therefore nothing new, but rather an expected task for the government, and thus the central bank, to analyze major changes and draw conclusions from them. The problem is essentially about cash being phased out by digital means of payment. In order to therefore solve the problem, the Riksbank has started a project to investigate whether or not the Riksbank should issue digital cash to the Swedish public, what the Riksbank calls an e-krona. To introduce an e-krona would be a major step, but for the public to not have access to a government alternative, seeing as cash usage is declining, is also a major step. No decision has been made yet regarding whether the e-krona will be introduced on the market or not. A decision that however has been made, is that the Riksbank is now working on building an e-krona to develop and assess the technique. Nonetheless, an introduction would undoubtedly have consequences for both the Riksbank and the commercial banks, which ultimately means it would have effects on the economy as a whole. What about regulatory aspects; is the Riksbank even allowed to issue an e-krona under current legislation? The answer is affirmative, to a certain extent. There are furthermore many other uncertainties regarding how an e-krona would affect the economy; the Riksbank does not fully answer many of the system issues in its project reports. The question of whether or not it even is up to the Riksbank to make a decision on the matter of an introduction is also questioned by the author in the thesis.

406	Dopad změn směnných kurzů na vzorek českých společností / The impact of changing exchange rates on Czech companies Klečka, Michal January 2016 (has links) This thesis analyses impact of exchange rate exposure in Czech Republic on sample of ten Czech companies. Empirical part of thesis builds on Nazl, Kar, Akel (2014) and through market-based approach states significant impact of exchange rate exposure for 40 % of companies. Higher robustness of results was achieved through improvements in the methodology which, contrary to related literature, eliminates endogeneity of market index through instrumental variable. Surprisingly, the correlations between exchange rates and stocks of Czech companies are positive. An alternative model considering ROA of individual companies as dependent variable was used to confirm these results. The resulting impact of exchange rate exposure of alternative model is opposite. This inconsistency of the results of both models is confusing. The sudden change in exchange rate policy of the Czech National Bank in November 2013 did not affect the sensitivity of the relationship between exchange rates and stocks. The reaction of stock market in November 2013 indicates that policy change made by CNB was not entirely expected. Contrary to the related literature, higher data aggregation decreases the significance of the exchange rate exposure, signifying higher ability of Czech companies to reduce exchange rate risk in longer...
407	Compliance at work: protecting identity and science practice under corporatisation Hunt, Lesley M. January 2003 (has links) When the New Zealand Government restructured the system of the public funding of research (1990-1992) it created Crown Research Institutes (CRIs) as companies operating in a global, market-led economy. One CRI, AgResearch, responded to this environment by corporatisation and instituted a normative system of control of workers which, through strategic plans, vision and mission statements, and performance appraisal processes, encouraged workers to adhere to company goals. This thesis, reporting on an ethnographic study of this CRI, shows how most scientific workers (technical workers and scientists alike) experienced insecurity through estrangement because the contributions they wished to make were less valued both in society and in their work organisation. They were excluded from participation in both organisational and Government policy-making, and felt they did not ‘belong’ anymore. Scientists in particular were also experiencing alienation (in the Marxist sense), as they were losing autonomy over the production of their work and its end use. Scientific workers developed tactics of compliance in order to resist these experiences and ostensibly comply with organisational goals while maintaining and protecting their self-identities, and making their work meaningful. Meanwhile, to outward appearances, the work of the CRI continued. This thesis adds to the sociology of work literature by extending the understanding of the concepts of compliance and resistance in white-collar work, particularly under normative control, by developing two models of resistance. It adds to the stories of the impact on public sector workers of the restructuring of this sector in New Zealand’s recent history, and develops implications for science policy and practice. compliance resistance identity work science practice restructuring corporatisation normative control AgResearch Crown Research Institute (CRI)
408	The confiscation of Pare Hauraki: The impact of Te Ao Pākehā on the Iwi of Pare Hauraki Māori; on the whenua of Pare Hauraki 1835-1997 and The Foreshore and Seabed Act 2004 / Te raupatutanga o Pare Hauraki Peters, Murray Hamaka January 2007 (has links) Kia mau ki te rangatiratanga o te Iwi o Hauraki Just as the whakataukī explains Hold fast to the power and authority of the Hauraki tribes the focus of this study is to examine and evaluate the impact of Te Ao Pākehā on Pare Hauraki lands and Tīkapa Moana under the mana of Pare Hauraki Māori and Pare Hauraki tikanga. The iwi of Pare Hauraki have land claims through the, (Wai 100) and the Hauraki Māori Trust Board, before the Waitangi Tribunal highlighting whenua issues and their impact on Pare Hauraki iwi. Also relevant is the foreshore and seabed issue which is documented leading on to the infamous Foreshore and Seabed Act 2004, (for Māori anyway), sparking widespread opposition by Māori throughout the country, and other supportive non-Māori groups because of the issue concerning Māori kaitiiakitanga and guardianship roles. This investigation will commence by outlining the histories of discovery and settlement of Pare Hauraki, the concept of mana-whenua/mana-moana as it applies to Pare Hauraki Māori and our tikanga, and then to subsequent issues leading to land alienation of the early 19th to late 20th cenutries and then to the foreshore issue of the early 21st Century. This research will include information showing that before 1840 to Te Tiriti o Waitangi and thereafter that Pākehā and various Crown agents, through legislation claimed the rights to the lands, waterways and oceanic areas under the kaitiakitanga of my tupuna of Pare Hauraki. Tupuna and other iwi members have expressed their disgust seeing the mana of their traditional lands, waterways, oceanic areas and kaitiaki roles slipping away from them through these activities. Therefore, this thesis is a response to those issues and the impact on (a), Māori as a people, and our tikanga Māori and (b), Pare Hauraki Māori as the kaitiaki/guardians of the Pare Hauraki rohe/territory in accordance with tikanga Māori, and the significance of the responsibilities which arise out of the Māori concepts of kaitiakitanga, manaakitanga and rangatiratanga.

409	Pulp fictions : the CCF government and the promise of a pulp industry in Saskatchewan, 1944-1964 Novosel, Tom Goran 11 June 2007 This thesis brings together for the first time, in an organised account, Saskatchewans search for a pulp industry. This thesis will show that, in a fundamental tension between goals of fiscal prudence and of economic growth, fiscal prudence won out again and again, to the point that the CCF governments could be characterised as risk-averse where pulp production was concerned. The cautious approach is in contradiction both to the activist reputation of the CCF governments and to their aggressive development of other resources, notably mining. Pulp offers an example of the contradictions that plagued the CCF governments and their policies for the north, contradictions that included disagreements between moderates and radicals over the roles of public and multinational enterprise, colonial attitudes towards the north, and risk aversion despite bold rhetoric and announcements.<p>The methodology used in this thesis has generally maintained an economic policy and political discourse, and incorporates mostly a top-down governmental approach. The personal papers of Tommy Douglas and Woodrow Lloyd provided CCF government correspondence and departmental memos that included premiers, ministers, deputy ministers, and departmental directors involved with the Department of Natural Resources, the Timber Board, the Industrial Development Office, and the Economic Advisory and Planning Board, and with pulp company officials. Furthermore, pulp reports, surveys, and studies helped contextualise all of the interrelated correspondences. To supplement government discourse I utilised the Prince Albert Daily Herald to gain an understanding of what issues the public was debating and found to be most important. comparative costs profits timber freight rates bond guarantees capital conservation regulation depletion crown corporations socialism investment monopoly incentives concessions assistance market access Ross Thatcher Clarence Fines Mike Kalmakoff Don Black dependent diversification provincial treasury vulnerability forestry Joe Phelps boom-bust cycles
410	FUNCTIONAL DIVERSITY OF FUNGI ASSOCIATED WITH DURUM WHEAT ROOTS IN DIFFERENT CROPPING SYSTEMS 2013 June 1900 (has links) Differences in pea (Pisum sativum L.) and chickpea (Cicer arietinum L.) microbial compatibility and/ or their associated farming practices may influence root fungi of the following crop and affect the yield. The main objective of this research was to explain the difference in durum wheat (Triticum turgidum L.) yield the year after pea and chickpea crops through changes in the functional diversity of wheat root fungi. The effect of fungicides used on chickpea on the root fungi of a following durum wheat crop was studied using plate culture and pyrosequencing. Pyrosequencing detected more Fusarium spp. in the roots of durum wheat after fungicide-treated chickpea than in non-fungicide treated chickpea. Plate culture revealed that the functional groups of fungi responded differently to fungicide use in the field but the effect on total community was non-significant. Highly virulent pathogens were not affected, but antagonists were suppressed. More fungal antagonists were detected after the chickpea CDC Luna than CDC Vanguard. Fungal species responded differently to the use of fungicides in vitro, but the aggregate inhibition effect on antagonists and highly virulent pathogens was similar. The effect of chickpea vs. pea previous crop and different chickpea termination times on root fungi of a following durum wheat crop was studied. The abundance of Fusarium spp. increased after cultivation of both cultivars of chickpea as compared to pea according to pyrosequencing and was negatively correlated with durum yield. Plate culture analysis revealed that fungal antagonists were more prevalent after pea than both cultivars of chickpea and chickpea CDC Vanguard increased the abundance of highly virulent pathogens. The abundance of highly virulent pathogens in durum wheat roots was negatively correlated to durum yield. Early termination of chickpea did not change the community of culturable fungi in the roots of a following durum crop. It is noteworthy that Fusarium redolens was identified for the first time in Saskatchewan and its pathogenicity was confirmed on durum wheat, pea and chickpea. The classical method of root disease diagnostics in cereals is based on the examination of the subcrown internode. I evaluated the method by comparing the fungal communities associated with different subterranean organs of durum wheat. The fungal community of the subcrown internode was different from that of roots and crown, suggesting cautious use of this method.
