Multicriteria analysis and GIS application in the selection of sustainable motorway corridor

Belka, Kamila January 2005 (has links)
<p>Effects of functioning transportation infrastructure are receiving more and more environmental and social concern nowadays. Nevertheless, preliminary corridor plans are usually developed on the basis of technical and economic criteria exclusively. By the time of environmental impact assessment (EIA), which succeeds, relocation is practically impossible and only preventative measures can be applied.</p><p>This paper proposes a GIS-based method of delimiting motorway corridor and integrating social, environmental and economic factors into the early stages of planning. Multiple criteria decision making (MCDM) techniques are used to assess all possible alternatives. GIS-held weighted shortest path algorithm enables to locate the corridor. The evaluation criteria are exemplary. They include nature conservation, buildings, forests and agricultural resources, and soils. Resulting evaluation surface is divided into a grid of cells, which are assigned suitability scores derived from all evaluation criteria. Subsequently, a set of adjacent cells connecting two pre-specified points is traced by the least-cost path algorithm. The best alternative has a lowest total value of suitability scores.</p><p>As a result, the proposed motorway corridor is routed from origin to destination. It is afterwards compared with an alternative derived by traditional planning procedures. Concluding remarks are that the location criteria need to be adjusted to meet construction</p><p>requirements as well as analysis process to be automated. Nevertheless, the geographic information system and the embedded shortest path algorithm proved to be well suited for preliminary corridor location analysis. Future research directions are sketched.</p>

A Feasibility Study for Using Commercial Off The Shelf (COTS) Hardware for Meeting NASA’s Need for a Commercial Orbital Transportation Services (COTS) to the International Space Station - [COTS]<sup>2</sup>

Davis, Chad Lee 01 August 2011 (has links)
The space vehicle system concept (i.e. resupply vehicle) described is based on the new direction that President George W. Bush announced on January 14, 2004 for NASA’s Human Exploration, which has the space shuttle retiring in 2011 following the completion of the International Space Station (ISS). This leads to a problem for the ISS community regarding the capability of meeting a sixty metric-ton cargo shortfall in resupply and the ability of returning large payloads, experiment racks and any other items too large to fit into a crew only type spacecraft like the Orion or Soyuz. NASA and the ISS partners have realized these future problems and started developing various systems for resupply to ISS, but none offer the capability for large up or down mass close to that of the shuttle. Without this capability, the primary purpose behind the ISS science mission is defeated and the ability to keep the station functioning properly is at risk with limited payload delivery (i.e. replacement hardware size and mass). There is a solution to this problem and a majority of the solution has already been designed, built, and flight tested. Another portion has been studied heavily by a team at NASA for use in a slightly different mission. Following the retirement of the space shuttle fleet and the loss of heavy up and down mass capability, the only solution to the problem is to design a new spacecraft. However, the budget and new direction for NASA will not allow for a costly new payload carrying spacecraft. The solution is to use existing commercial off the shelf (COTS) hardware to minimize the costs of developing a totally new system. This paper will discuss the technical feasibility of this conceptual configuration.

Framing Biodiversity Conservation Discourses in South Africa: Emerging Realities and Conflicting Agendas within the Great Limpopo Transfrontier Conservation Area.

Whande, Webster. January 2009 (has links)
<p>This dissertation explores local people's framing of externally driven biodiversity conservation approaches in the context of transfrontier conservation initiatives. It uses data from the Madimbo corridor, a specific locality within the Great Limpopo Transfrontier Conservation Area, situated to the northeast of South Africa along the South Africa-Zimbabwe boundary. It shows that livelihoods, historical experiences with external interventions and exclusion from policy-making processes and programme implementation influence local strategies for engaging with external interventions. Thus, an analysis of framing of external interventions at a local level should establish the following: the role of natural resources in sustaining local livelihoods / local historical experiences with an external intervention / iii) the nature of multi-level actor interactions from local resource dependent people, to national, regional and global actors involved in or affected by an intervention. The study uses a detailed case study of Bennde Mutale village to trace local people&rsquo / s ideas, ways of speaking and actions in response to the implementation of a large-scale transfrontier conservation initiative. The study finds that local livelihoods play a central role in local responses to the changes that transfrontier conservation bring upon people's lives. Many see further exclusion, while some also see and hope for a restoration of the socio-cultural border region. The globally significant biodiversity - to be conserved for &lsquo / future generations&rsquo / &ndash / at the same time constitutes the natural resources that sustain local people&rsquo / s livelihoods. Further, local livelihoods are more diverse than is commonly acknowledged in literature advocating for transfrontier conservation. This lack of acknowledgement of local diversification contributes to the main observation made in this study: that current processes of transfrontier conservation end up replicating and re-inventing the multiple forms of exclusion that have characterised state conservation practices for over a century. While transfrontier conservation enables the freer movement of wildlife, it in fact further constrains the movements of people whose mobility within less closely controlled border regions remains centrally important to survival. At the same time, state actors come into the area with contradicting and conflicting demands ranging from the beneficial advocacy role for land rights to the enforcement of conservation through fences and game rangers, experienced as a direct infringement on livelihood possibilities. The study concludes that there is a need to rethink transfrontier conservation interventions. The diversity of local livelihood approaches needs to be considered more centrally and clearer understanding needs to be developed of how the promises of opportunities, betterment of lives and increased human mobility actually unfold in practice. In order to succeed and deliver on site - not only to high-class tourists seeking to view unique biodiversity but to local people - transfrontier conservation efforts need to engage multiple actors directly from the ground up and throughout the process of policy-making, programme conceptualisation and implementation.</p>

European Union

Aydin, Ayse Esra 01 July 2012 (has links) (PDF)
This thesis examines the bilateral relations of European Union and Russia in terms of energy trade. The main question of this thesis is whether European Union could realize its energy strategies of supply security and supply diversification in its natural gas trade with Russia. The main argument of this thesis is / Russia has been undermining the EU&rsquo / s energy strategy, by using the contradictions between the EU&rsquo / s energy strategy priorities of supply security and supply diversification. Emphasizing the significance of supply security for the European Union, Russia undermines the EU-sponsored projects of supply diversification. The fact that, Russia will be the principal supplier of natural gas to Europe, is likely remain as the key actor in energy market of EU. However, Russia is also dependent on EU for its hydrocarbon exports. Consequently Russia&rsquo / s role as EU&rsquo / s primary supplier in natural gas , and EU&rsquo / s role as Russia&rsquo / s main hydrocarbon importer, are likely to be the main factor that will continue to shape the thereon energy security in the foreseeable future.

An Assessment Of The Policy Shifts Of The Turkish Central Banking Since 2001

Senyarar Bayrak, Ipek 01 January 2013 (has links) (PDF)
The understanding of central banking has evolved several times in the history. Different economic and political conditions shaped the structure of monetary policy and the stance of central banks. The Central Bank of Republic of Turkey (CBRT) also has experienced several reactionary policy shifts throughout its history. Nowadays, majority of central banks have started to follow financial stability programs after the Global Financial Crisis of 2008-09. The CBRT was one of the followers of financial stability targeting and has started to implement a new monetary policy structure after the Global Financial Crisis. The new monetary policy of the CBRT in which the financial stability was put nearby price stability came up with new challenges. Therefore in this thesis, we elaborate on the challenges of the CBRT and propose policy suggestions for the possible deficiencies of the new structure of the CBRT. We argue that the experiences of the CBRT in the inflation targeting period and the macroeconomic conditions of both during and post crisis period have shaped the new structure of the monetary policy, and the new policy mix of the CBRT may not be successful in all its targets at the same time because of the existence of &ldquo / macroeconomic quadrilemma&rdquo / tradeoffs as well as because of the ineffectiveness of the tool portfolio of the CBRT.

Konsekvenser vid slopandet av korridormetoden : Engångseffekten på eget kapital / Consequences of abolishing the corridor method : One time effect on equity

Jarnbo, Cecilia, Ljungberg, Sophie January 2015 (has links)
Hur företag påverkades av slopandet av korridormetoden varierade från företag till företag. Dock hade alla undersökta företag som tillämpat korridormetoden räkenskapsår 2012, ackumelerade underskott. Den totala genomsnittliga effekten på eget kapial blev en minskning med -4,49 procent. En sjättedel av företagen i undersökningen vidtog någon åtgärd för att förebygga en negativ effekt på eget kapital. Den främsta åtgärd som dessa företag hade vidtagit, var att de successivt hade övergått till avgiftsbestämda pensionsplaner under de senaste åren och stängt de förmånsbestämda pensionsplanerna, vilket har förebyggt en negativ effekt. En ytterligare anledning till varför effekten inte blev så stor som befarades i media, kan bero på att en del företag valde att tillämpa den reviderade IAS 19 i förtid, det vill säga under tidigare räkenskapsår. / How the corporates equity was affected due to the abolishment of the corridor method varies from corporate to corporate. However, all investigated corporates in the essay which practiced the corridor method the fiscal year 2012 had an accumulated deficit. The total average effect on equity shows a decrease by -4,49 percent. One sixth of the corporates reviewed performed preventive actions to mitigate a negative effect on equity. One foremost action these corporates performed was to move from defined benefit plans to contribution plans the last years and close the defined benefit plans. One additional cause why the effect on equity was not as big as the media predicted, could be because some corporates choose to practice the revised IAS 19 in their previous fiscal years.

Esthetics and Smile Characteristics Evaluated by Laypersons: A comparison of Canadian and US data

McLeod, Catherine E. 25 June 2010 (has links)
Objective: To collect data regarding Canadian laypersons perceptions of smile esthetics and compare these data to US data in order to evaluate cultural differences. Methods: Using Adobe® Photoshop® 7, a digital image of a posed smile of a sexually ambiguous lower face was prepared so that hard and soft tissue could be manipulated to alter Buccal Corridor (BC), Gingival display (GD), Occlusal Cant (OC), Maxillary Midline to Face Discrepancy (MMFD) and Lateral Central Gingival Discrepancy (LCGD). Adult Canadian laypersons (n=103) completed an interactive computer-based survey of 29 randomized images to compare smile preferences for these variable. The custom survey was developed to display fluid, continuously appearing modifiable smile variables using MATLAB® R2008 for presentation. These data were compared to previously published data for US laypersons. Statistical inference was determined using Wilcoxon Rank Sum tests. Results: Canadian laypersons were more sensitive in detecting deviations from ideal and had a narrower range of acceptability thresholds for BC, GD, OC, MMFD and LCGD. Ideal esthetic values were significantly different only for BC. Conclusions: It appears cultural differences do exist related to smile characteristics. Clinically significant differences in the preference of the smile characteristics were found between Canadian and US laypersons. Canadian laypersons, on average, were more discriminating to deviations from ideal and had a narrower range of acceptability.
