Gas mass-flow meters: Principles and applications

Gas mass-flow meters (GMFM) for original equipment manufacturers (OEM) applications are presently found in a relatively easy and cheap way. GMFM may be applied in a number of different situations but technical formation concerning its principles of measurement and applications are still misleading. In this paper, the principles of GMFM measurement are discussed and the operating parameters are clarified. A concept of gas mass-flow response factor is introduced and further used in a model for gas mass-flow measurement that is suitable to any gas mixture of known composition. In addition, a model for the application of GMFM to dynamic volumetric methods of dilution is presented and generalized

Project management metrics and creation of an operational dashboard

Mestrado Bolonha em Mathematical FinanceThis report describes my 3-month internship at Unipartner IT Services S.A., that occurred from March to June 2022. This internship focused on activities mainly related to project management. Unipartner IT Services S.A is an information technology services company that works with government organizations, financial institutions and commercial companies with the aim of solving the most demanding IT and business challenges. During this internship, I performed a gap analysis between the information available in the client’s database and a set of performance metrics that needed to be computed, with the objective of understanding what information was missing, and to improve the quality of the service provided. Understanding and analysing the project management process was an important task prior to all others: it was essential learning what to do and how to do it, depending on the characteristics of contracts and clients at hand. I also created a dashboard in Power BI, based on the company’s database (Azure DevOps), gathering all information regarding contracts, that can be presented to a client in order to illustrate the progress.info:eu-repo/semantics/publishedVersio

The Forward- and the Equity-Premium Puzzles: Two Symptoms of the Same Illness?

We build a pricing kernel using only US domestic assets data and checkwhether it accounts for foreign markets stylized facts that escape consumptionbased models. By interpreting our stochastic discount factor as the projection ofa pricing kernel from a fully specified model in the space of returns, our results indicatethat a model that accounts for the behavior of domestic assets goes a longway toward accounting for the behavior of foreign assets. We address predictabilityissues associated with the forward premium puzzle by: i) using instrumentsthat are known to forecast excess returns in the moments restrictions associatedwith Euler equations, and; ii) by pricing Lustig and Verdelhan (2007)'s foreigncurrency portfolios. Our results indicate that the relevant state variables that explainforeign-currency market asset prices are also the driving forces behind U.S.domestic assets behavior.

The forward- and the equity-premium puzzles: two symptoms of the same illness?

Using information on US domestic financial data only, we build a stochastic discountfactor—SDF— and check whether it accounts for foreign markets stylized factsthat escape consumption based models. By interpreting our SDF as the projection ofa pricing kernel from a fully specified model in the space of returns, our results indicatethat a model that accounts for the behavior of domestic assets goes a long waytoward accounting for the behavior of foreign assets prices.

A Ligação da Escola ao Meio como Factor de Desenvolvimento - Uma Reflexão

O desenvolvimento de uma região passa muito pela natureza da respectiva economia local. Neste sentido é importante que esta se desenvolva não apenas em resultado das decisões de localização de empresas dotadas de mobilidade, mas sobretudo pela intensificação das "interdependências industriais locais" no âmbito de um sistema gerador de economias de aglomeração. Este é um caminho longo que tem essencialmente duas fases, uma em que se constrói capacidade profissional e competência técnica, em que se assegura a manutenção das unidades produtivas, do volume de emprego, etc.. A seguinte corresponde ao seu aprofundamento, com a divisão do trabalho entre empresas e o desenvolvimento de novas funções numa lógica de integração produtiva. As economias de aglomeração desenvolvem-se não só pela densidade das interdependências sectoriais, mas também pelas características da mão-de-obra local (disponibilidade, competências e qualificações) e pelo ambiente favorável à circulação da informação que promovem uma certa aprendizagem colectiva
