Estudio comparativo de diferentes soluciones de fachada y cubierta para un edificio residencial

[ES]En el proyecto se analizan diferentes soluciones de fachada y cubierta de un edificio residencial, buscando la eficiencia energética y la economía. Para ello, partiendo de un caso concreto, se estudian las cargas térmicas del edificio existente y de otras dos soluciones posibles. En estas además, se utilizan materiales sostenibles, con el fin de hacer el menor impacto medioambiental posible. Se ha analizado también la rentabilidad de estas soluciones, para comprobar cuál es la más adecuada desde un punto de vista económico.

Skate elektriko baten gauzatzea, hautabideak eta diseinua.

[EU]Lan honetan hutsetik hasita skate motorizatu baten diseinu bat egin da, Industria Teknologian Ingeniaritzako Graduan eskuratutako jakintzak erabiliz. Skatea gazteengan oso erabilia den garraiobide bat da aisia dela-eta, eta sinpletasuna eta ekonomia kontuan hartuta, aisia eta ingurugiroarekiko konpromisoa nahasten dira diseinu honekin. Lanak bide argi bat dauka: hasieran merkatuaren egoera aztertzen da, gero diseinu posible batzuk proposatu ahal izateko, eta hortik aukera bat jorratu ahal izateko. Hortaz, prozesua hasieratik hasita, egitura hau izango du lanak: Hasteko, skate motorizatuen merkatuko egoera zein den aztertzen da, ondoren eta helburuak zeintzuk diren kontutan izanda, diseinu posible batzuk proposatu ahal izateko, alternatiben analisien atalean ageri direnak. Proposamen horiek aztertu egiten dira, alde on eta txarrak desberdinduz eta horietako soluzio bat aukeratuz. Aukeratutako diseinuaren CAD modelo bat eraikitzen da, ondoren egoera fisikoa matematikoki modelizatzeko eta beharrezko kalkuluak egin ahal izateko, metodologia atalean eta eranskinetan ageri direnak, hala nola, azelerazio jakin bat lortzeko behar den potentzia, transmisioan beharrezkoak diren kalkuluak kokatu beharreko elementuak zeintzuk diren erabaki ahal izateko, etab. Bide honetan, jorraturiko diseinuaz gain beste diseinu optimizatu eta konplexuago bat proposatzen da, ikerketa bidea zabalik duena, enpresa mundura gehiago zuzendua. Azkenik, lana burutzeko bete behar izan diren ataza bakoitzaren deskribapena eta iraupena, aurrekontua eta gastu aitorpena, arriskuen analisia eta proiektu honetatik atera ditugun ondorioak ematen dira.

Income Taxation and Growth in an OLG Economy: Does Aggregate Uncertainty Play any Role?

We analyze the effects of capital income taxation on long-run growth in a stochastic, two-period overlapping generations economy. Endogenous growth is driven by a positive externality of physical capital in the production sector that makes firms exhibit an aggregate technology in equilibrium. We distinguish between capital income and labor income, and between attitudes towards risk and intertemporal substitution of consumption. We show necessary and sufficient conditions such that i) increments in the capital income taxation lead to higher equilibrium growth rates, and ii) the effect of changes in the capital income tax rate on the equilibrium growth may be of opposite signs in stochastic and in deterministic economies. Such a sign reversal is shown to be more likely depending on i) how the intertemporal elasticity of substitution compares to one, and ii) the size of second- period labor supply. Numerical simulations show that for reasonable values of the intertemporal elasticity of substitution, a sign reversal shows up only for implausibly high values of the second- period’s labor supply. The conclusion is that deterministic OLG economies are a good approximation of the effect of taxes on the equilibrium growth rate as in Smith (1996).

Financial Futures Markets and Their Impact on the Real Economy in Middle and Low Income Countries

This project analyses the influence of the futures market on middle and low income countries. In it, I attempt to show that investments made by large investment funds in this market, as well as by certain pension plans, bring major consequences whose effects are more evident in less developed countries. The cornerstones of the work are as follows; to attempt to see the existing relationship between the commodity futures market and its underlying assets; analysing products such as wheat, rice and corn in-depth, because these are the most basic foodstuffs at a global level; to determine how an increase in trading in these markets can affect the lives of people in the poorest countries; to analyse investor concern regarding the consequences that their investments may have. Throughout the project we will see how large speculators use production forecasting models to determine the shortage of a commodity in order to take a position in the futures market to profit from it. In addition we will see how an increase in trading in this market causes an increase in the price of the underlying asset in the spot market. As for investor concern, I can say it is negligible, but the idea of running pension plans or investment funds that follow some social criteria has been welcomed by those interviewed, which makes me think that different legislation is possible. This legislation will only come into existence if it is demanded by the people. A fact that now becomes complicated because without a minimum financial basis, they cannot even know how the large investment funds trade with hunger in the world. The day when most people understand how large speculators profit from famine will be the day to put pressure on governments to begin to put limits on speculation. This makes financial awareness necessary in order to achieve a curb in excessive speculation.
