1. Testing the consumption-based CAPM using the stochastic discount factor
Abstract This article investigates the problem of optimal intertemporal consumption in the CCAPM setup from a new empirical perspective. The econometric analysis is based on use of the equality between the stochastic discount factor (SDF) and the marginal rate of intertemporal substitution of consumption, which in the CCAPM is equivalent to the Euler equatio

2. EFFECT OF WAVELET DE-NOISING ON THE CLASSIFICATION OF PIG BEHAVIOUR
ABSTRACT To efficiently eliminate the noise generated by the triaxial accelerometer when collecting pigs’ behavioural data, this paper adopted SNR and MSE as the indexes to evaluate the de-noising effect of pigs’ acceleration signal under various combinations of wavelet basis, decomposition layer, threshold rule and threshold function. Based on the optim

3. Development and application of an automatic tool for the selection of control variables based on the self-optimizing control methodology
Abstract Rules for control structure design for industrial processes have been extensively proposed in the literature. Some model-based methodologies have a sound mathematical basis, such as the self-optimizing control technology. The procedure can be applied with the aid of available commercial simulators, e.g., PRO/IITM and AspenPlus®, from which the conv

4. A negative expiratory pressure test during wakefulness for evaluating the risk of obstructive sleep apnea in patients referred for sleep studies
OBJECTIVE: Obstructive sleep apnea is characterized by increased upper airway collapsibility during sleep. The present study investigated the use of the negative expiratory pressure test as a method to rule out obstructive sleep apnea. METHODS: Flow limitation was evaluated in 155 subjects. All subjects underwent a diurnal negative expiratory pressure test a

5. Estudo prospectivo randomizado do tratamento endoscópico da coloproctopatia actínica crônica hemorrágica: eletrocauterização com plasma de argônio versus bipolar. / Randomized and prospective study of endoscopic treatment to hemorrhagic chronic radiation coloproctopathy: argon plasma eletrocauterization versus bipolar.
Introduction: Chronic radiation coloproctopathy (CRCP) is a well-recognized complication of radiotherapy. Rectal bleeding is the most common symptom of radiation injury and the optimal endoscopic treatment of bleeding due to CRCP is still controversial. Aim: To compare the efficacy and safety of bipolar eletrocauterization (BEC) and argon plasma eletrocauter

6. Testing the Optimality of Aggregate Consumption Decisions: Is there Rule-of-Thumb Behavior?
Consumption is an important macroeconomic aggregate, being about 70% of GNP. Finding sub-optimal behavior in consumption decisions casts a serious doubt on whether optimizing behavior is applicable on an economy-wide scale, which, in turn, challenge whether it is applicable at all. This paper has several contributions to the literature on consumption optimal

7. Ensaios sobre política monetária e fiscal no Brasil
Esta tese apresenta três ensaios sobre política monetária e fiscal dentro do atual regime de metas de inflação. O primeiro ensaio buscou estudar uma possível integração monetária-fiscal ao determinar uma regra ótima de política monetária com restrição fiscal, analisando os efeitos de diversas preferências sobre a regra ótima em função da al

8. Formulation and evaluation of baking powders to be use in cakeâs pre-mixtures / FormulaÃÃo e avaliaÃÃo de fermentos quÃmicos para prÃ-mistura de bolo
A baking podwer is a product formed by a mixture of acid agents with sodium bicarbonate which with the influence of the heat and/or humidity, produces carbon dioxide capable of expanding the dough made with flour and starches, increasing its volume and the porosity. The objective of the present work was to optimize a formula for a baking powder to be used in

9. Design and optimization of new simulated moving bed plants
The simulated moving bed (SMB) technology has attracted considerable attention for its efficiency as a chromatographic adsorptive separation. It has been increasingly applied to the separation of binary mixtures with low separation factors, namely to separate isomers. Although quite a vast amount of information has been published concerning the simulation an

10. OPÇÕES REAIS HÍBRIDAS COM APLICAÇÕES EM PETRÓLEO / HYBRID REAL OPTIONS WITH PETROLEUM APPLICATIONS
This methodological and normative thesis extends the modern economic valuation theory of projects under uncertainty, known as real options theory, from the point of view of an oil company that optimizes the allocation of investment and resources. The real options theory is combined with other theories - so the name hybrid real options - in order to perform a

11. WELFERE ANALYSIS OF MONETARY POLICY UNDER FISCAL RESTRICTION / AVALIAÇÃO DE BEM-ESTAR DE POLÍTICA MONETÁRIA SOB RESTRIÇÃO FISCAL
The dissertation consists in the development of a model to evaluate the welfare effects of monetary policy in an economy where the government faces some restriction to debt financing. The government, in the model, is able to finance its expenditures by issuing public debt or levying two kinds of taxation: lump sum and distortionary taxes. The hypothesis adop

12. THE IMPACT OF THE VOLATILITY IN THE REAL OPTION VALUATION: AN APPLICATION TO BRAZILIAN INVESTMENTS IN TELECOMMUNICATIONS AND PETROLEUM / A INFLUÊNCIA DA VOLATILIDADE NA AVALIAÇÃO DAS OPÇÕES REAIS: O CASO DOS INVESTIMENTOS EM TELECOMUNICAÇÕES E PETRÓLEO NO BRASIL
The net present value valuation of investments in capital stock is based on the following rule: the present value of the expected stream of profits from the investment should be greater than the required expenditures. This kind of rule ignores the value of waiting related to the ability of delaying an irreversible investment. The valuation of real assets wit
