Texto completoHigh property market transparency (Jones Lang LaSalle 2006b) and predominance of Listed Property Trusts (LPT) as CMBS issuers (Standard & Poor’s 2005b), who legally have to report their activities and underlying collateral performance to regulatory regimes such as Australian Stock Exchange (ASX)/Australian Securities and Investment Commission (ASIC) and their equity partners, have contributed to the success of the Australian CMBS market. Furthermore, the positive commercial real estate market outlook should support future CMBS issuance, with LPTs continuing their dominance as issuers. In investigating property risk assessment in Australian CMBSs, all the CMBSs issued over a six year period of 2000 to 2005 were obtained from Standard and Poor’s presale reports as found in their Ratings Direct database to identify and review how property risk factors were addressed in all issues and within specific property asset classes following the delineation of property risk by Adair and Hutchinson (2005). Adequate assessment of property risk and its reporting is critical to the success of CMBS issues. The proposed framework shows that assessing and reporting property risk in Australian CMBSs, which are primarily backed by direct property assets, under the headings of investment quality risk, covenant strength risk, and depreciation and obsolescence risk can easily be done. The proposed framework should prove useful to rating agencies, bond issuers and institutional investors. Rating agencies can adopt a more systematic and consistent approach towards reporting of assessed property risk in CMBSs. Issuers and institutional investors can examine the perceived consistency and appropriateness of the rating assigned to a CMBS issue by providing inferences concerning property risk assessment.
The ultimate goal of structuring CMBS transactions is to obtain a high credit rating as this has an impact on the yield obtainable and the success of the issue. The credit rating process involves highly subjective assessment of both qualitative and quantitative factors of a particular company as well as pertinent industry level or market level variables (Huang et al. 2004), with the final rating assigned by a credit committee via voting (Kwon et al. 1997). As such, credit rating agencies state that researchers cannot replicate their ratings quantitatively since their ratings reflect each agency’s opinion about an issue’s potential default risk and relies heavily on a committee’s analysis of the issuer’s ability and willingness to repay its debt. However, researchers have replicated bond ratings on the premise that financial ratios contain a large amount of information about a company’s credit risk. In this study, quantitative analysis of determinants of CMBS credit ratings issued by Standard and Poor’s from 2000 – 2006 using ANNs and OR and qualitative analysis of factors considered necessary to obtain a high credit rating and pricing issues necessary for the success of an issue through mail surveys of arrangers and issuers are undertaken. Of the quantitative variables propagated by credit rating agencies as being important to CMBS rating, only loan-to-value ratio (LTV) is found to be statistically significant, with the other variables being statistically insignificant using OR. This leads to the conclusion that statistical approaches used in corporate bond rating studies have limited replication capabilities in CMBS rating and that the endogeneity arguments raise significant questions about LTV and debt service coverage ratio (DSCR) as convenient, short-cut measures of CMBS default risk.
However, ANNs do offer promising predictive results and can be used to facilitate implementation of survey-based CMBS rating systems. This should contribute to making the CMBS rating methodology become more explicit which is advantageous in that both CMBS investors and issuers are provided with greater information and faith in the investment. ANN results show that 62.0% of CMBS rating is attributable to LTV (38.2%) and DSCR (23.6%); supporting earlier studies which have listed the two as being the most important variables in CMBS rating. The other variables’ contributions are: CMBS issue size (10.1%), CMBS tenure (6.7%), geographical diversity (13.5%) and property diversity (7.9%) respectively. The methodology used to obtain these results is validated when applied to predict LPT bond ratings. Both OR and ANN produce provide robust alternatives to rating LPT bonds, with no significant differences in results between the full models of the two methods. Qualitative analysis of surveys on arrangers and issuers provides insights into structuring issues they consider necessary to obtain a high credit rating and pricing issues necessary for the success of an issue. Rating of issues was found to be the main reason why investors invest in CMBSs and provision of funds at attractive rates as the main motivation behind CMBS issuance. Furthermore, asset quality was found to be the most important factor necessary to obtain a high credit rating supporting the view by Henderson and ING Barings (1997) that assets backing securitisation are its fundamental credit strength.
In addition, analyses of the surveys reveal the following: • The choice of which debt funding option to use depends on market conditions. • Credit tranching, over-collateralisation and cross-collateralisation are the main forms of credit enhancement in use. • On average, the AAA note tranche needs to be above AU$100 million and have 60 - 85% subordination for the CMBS issue to be economically viable. • Structuring costs range between 0.1% – 1% of issue size and structuring duration ranges from 4 – 9 months. • Preferred refinancing options are further capital market issues and bank debt. • Pricing CMBSs is greatly influenced by factors in the broader capital markets. For instance, the market had literary shut down as a result of the “credit crunch” caused by the meltdown in the US sub-prime mortgage market. These findings can be useful to issuers as a guide on the cost of going to the bond market to raise capital, which can be useful in comparing with other sources of funds. The findings of this thesis address crucial research priorities of the property industry as CMBSs are seen as a major commercial real estate debt instrument. By looking at how property risk can be assessed and reported in a more systematic way, and investigating quantitative and qualitative factors considered in structuring CMBSs, investor confidence can be increased through the increased body of knowledge. Several published refereed journal articles in Appendix C further validate the stature and significance of this thesis. It is evident that the property research in this thesis can lead aid in the revitalisation of the Australian CMBS market after the “shut down” caused by the melt-down in the US sub-prime mortgage market and can also be used to set up property-backed CMBSs in emerging countries where the CMBS market is immature or non-existent.

A aplicação de técnicas de Análises de Componentes Principais (ACP), Redes Neurais Artificiais (RNA), Lógica Fuzzy e Sistema Neurofuzzy para investigar as alterações da característica da água das barragens de Utinga e do Bita que abastecem de água bruta a ETA Suape é de fundamental importância em função do grande número de variáveis utilizadas para definir a qualidade. Neste trabalho, foram realizadas 10 coletas de água em cada área, no período de novembro de 2007 a agosto de 2012, totalizando 120 amostras. Ainda que o conjunto de dados experimentais obtidos seja reduzido, houve múltiplos esforços em demanda da aquisição de informações da qualidade da água junto aos órgãos oficiais de monitoramento ambiental. Os resultados mostraram uma tendência à degradação da propriedade da água das barragens em decorrência da presença de microrganismos, sais e nutrientes, responsáveis pelo processo de eutrofização, o que se configurou pela maior concentração de fósforo total, Coliformes termotolerantes, e diminuição de pH e OD, provavelmente devido à ocorrência de descarte de efluentes da agroindústria canavieira, industrial e doméstico. A ACP caracterizou mais 76% das amostras permitindo visualizar a existência de mudanças sazonais e uma pequena variação espacial d`água nas barragens. A condição da água das duas barragens foi modelada satisfatoriamente, razoável precisão e confiabilidade com os modelos estatístico e computacionais, para uma quantidade de parâmetros e dados ambientais, que embora limitados foram suficientes para realização deste trabalho. Ainda assim, fica evidente a eficiência e sucesso da utilização do Sistema Neurofuzzy (coeficiente de regressão de 0,608 a 0,925) que combina as vantagens das Redes Neurais e da Lógica Fuzzy em modelar o conjunto de dados da qualidade da água das barragens de Utinga e Bita.
The application of techniques such as the Principal Components Analysis (PCAs), Artificial Neural Networks (ANNs), Fuzzy Logic and Neuro-fuzzy Systems for investigating the changes in the water quality characteristics in the Utinga and Bita dams, which supplies raw water to the Suape Wastewater Treatment Plant (WWP), is of great importance due to the high number of variables used to define water quality. In this work were collected 10 water samples used to define water quality, in a period ranging from November 2007 to August 2012, with a total of 120 samples. Although the experimental dataset was limited, there were multiple efforts in gathering information from the Environmental Control Agencies. The results showed a tendency of degradation of the water properties in the dams studied due to the presence of microorganisms, salts and nutrients, responsible for the eutrophication process; result of the higher concentration of total phosphorus, Thermotolerant Coliforms and decrease in pH and DO, probably from the discharge of the sugarcane agroindustry and domestic waste. The PCAs characterised more than 76% of the samples collected, and consequently observing the existence of seasonal changes and small spatial variation of water levels in the dams. The water quality conditions in both dams were satisfactorily modelled, obtaining a reasonable precision and statistical and computational reliability for a certain amount of parameters and environmental data that, even though considered limited, were enough to run this trial. Nonetheless, it becomes evident the efficiency and success in using the Neuro- Fuzzy System (regression coefficient of 0.608 to 0.925), which combines the advantages of both the Neural Networks and Fuzzy Logic in modelling the water quality dataset in the Utinga and Bita dams.

Texto completoThe quite-systematic scarcity of sampled data hampers the study of underground media. This is why the question remains of getting suited interpretations based on in situ data to evaluate macroscopic parameters ruling flow and mass transport in underground reservoirs. The aim of this work is to invert dynamic data by means of tools with a physical view on the reservoir functioning (opposed here to a systemic approach). Hydraulic interference testing has been held in two campaigns over the fractured limestone aquifer of the Hydrogeological Experimental Site (HES) in Poitiers (France). Drawdown data are interpreted by enhanced dual-medium approaches, with special care given to karstic draining observed on data of the second campaign. A tool for mass transport inversion is also developed with calculations handled by a Lagrangian approach in time over bond networks. Among various refinements, inversion is coupled with an analytical derivation of the model sensitivity to parameters. Finally, the trace of the network is eliminated by substituting the classical transport equations by the Langevin equations. The latter include a force field yielding a hyperbolic term that would mimic the eventual channelling effects of a network. Several analytical developments of the mean displacement and dispersion of particles, both in transient and asymptotic context, testify that the substitution is feasible. This work should be pursued however, for instance by addressing with the tools mentioned above field tracer test experiments carried out in various contexts

Texto completoSugar allocation mediated by membrane transporters is strongly affected by water deficit. The sequences of 63 sugar transporters were identified in Grapevine. The in silico analysis identify 7 monosaccharide transporters subfamilies and several cis elements in the promoter regions. Macroarray expression analysis showed that 4 sugar transporter genes are strongly expressed in all vegetative organs (VvHT1, VvHT3, VvPMT5, VvSUC27), some others are preferentially expressed in mature leaf (VvHT5), in root (VvHT2), in seed (VvHT3, VvHT5) and 3 genes are regulated during berry development (VvHT2, VvTMT1, VvTMT2). Macroarray gene expression analysis showed that VvHT5, VvSUC11, VvGIN2 and VvMSA are up-regulated in mature leaves under drought conditions and that VvHT1 was down-regulated. Water deficit triggers a strong accumulation of glucose, fructose and sucrose in water stressed leaves. VvMSA gene was overexpressed or silenced in grape embryogenic cells by genetic transformation. The silencing of VvMSA affects glucose uptake activity and VvHT1 expession. The Grapevine plants phenotype and the expression of VvHT1 and VvMSA expression were studied under both in vitro and ex-vitro conditions. For the first time, the involvement of sugar transporters and VvMSA in the response to water stress in Grapevine is demonstrated. A model for sugar signalling involved in VvHT1 gene expression is proposed, including a disaccharide pathway and two glucose regulatory mechanisms, one VvMSA-dependent and another VvMSA-independent. Finally, our results reveal the importance of VvHT1 hexoses transporter under heterotrophic conditions

Texto completoThough the analysis of the moral monodic conductus by the poet, preacher and theologist Philip the Chancellor, the rhetorical qualities of this work are revealed both by words and music. They have a complex relationship either by enhancing the sounds of words, by clarifying their meaning or by setting a learned construction to be understood by people used to the subtelties of latin rhythmic poetry. Rules and figures are dictated by the will to deliver a moral message, these techniques being derived from others practices of speech. The poet-composer conceives the conductus with the same habits as the ones of the orator and the singing voice is an efficient means of teaching a large and varied audience. Each song seems to fit is own purpose by the sounds of the language, by the structure patterns or by melodic creation. The sung word thus becomes a weapon against all sinners and vices

Texto completoMany of the technologies used in the modern systems of aid to terrestrial navigation go back to approximately a quarter of century. Generally, the main systems in use in the equipments for terrestrial Navigation are the Global Positioning Systems (GPS) and the Inertial Navigation Systems (INS). Such technological apparatus, need fundamental components of high or quite almost quality, which cause progressively growing market costs and can satisfy the most various range of applications in the navigation field, from the vehicular terrestrial one to the aerospace application, but also including handling applications or the management of vehicular fleets. In the last few years, the navigation systems have seen applications on a large scale, as the terrestrial navigation aid systems, in particular with the use of the GPS system. In order to avoid the disadvantages that it can cause, integrated low-cost systems for terrestrial navigation have been lately developed with applications on a large scale, among which, for important technical and economic aspects, the integrated INS/GPS system. The need to avoid the low quality of the used sensors led to the application of mathematical models able to correct the sensors’ answers. From here, one of the most used instrument throughout the years has been the Kalman filter, as an optimal linear Gaussian estimator in the data fusion INS/GPS. However, as multi-sensor integration methodology, it has various limits. The INS correction is needed either to get a more reliable answer in the short route compared the GPS-based navigation system, and to generate a data base in which a series of information are collected, among the necessary cinematic, geometric and environmental characteristics, in case the GPS signal is absent or of low quality. For that purpose, the attempt is to make the navigation system intelligent: the Kalman filter has been shown to be in the last years the reference model which has addressed the research to the use of intelligent models, such as for example the fuzzy logic, the genetic algorithms or the neural networks. The latter can make the integrated INS/GPS systems intelligent, or capable to take independent decisions in the data correction, after a learning process. The aim which has been reached is the use of the Artificial Neural Networks (ANN), in order to compensate for the answer of the INS system, in case the GPS outage occurred. In such situations, due to the unavoidable drifts caused by the INS random walk effects, a correction of the inertial data is needed, through the Neural Networks. A research of the models more related to this kind of data has been necessary, as well as a tuning of the networks. Therefore it has been developed either a storage system for the sensitive data, based on the updating of the network memory, (the weights), and a correction system of the inertial data. The evaluation has been carried out on many test cases and it has shown a definite improvement in performance compared to the use of the correction with conventional systems. Such applications, as also emphasized in scientific works, can be considered as a method for the future developments of the new integrated platforms for terrestrial navigation. Moreover, they can supply attitude configuration needed for the control of the autonomous systems and their low market costs allow a large scale applications, and also advantages in the road safety field and the reconstruction of accidental events.
