Metaphysics in the Work of Charles Darwin

It is not hard to see how two visions of nature are intertwined in Darwin’s Journal of Researches: one vision, the province of romantic authors depicting the sentiments awakened by certain landscapes, the other, the domain of natural scientists describing the world without reference to the aesthetic qualities of the scenery. Nevertheless, analyses of this double perspective in Darwin’s work are relatively rare. Most scholars focus on Darwin, the scientist, and more or less ignore the aesthetic aspects of his work. Perceiving the gradual transformation of Darwin’s world view, however, depends on analyzing the two different modes in which Darwin approached and perceived the world. While one can, on occasion, find commentaries on the beauty of the natural world in Darwin’s early work, the passage of time produces a modification in the naturalist’s manner of perceiving nature. This does not, however, mean that Darwin ceases to find beauty in nature; on the contrary, the disenchantment, in Max Weber’s words, that Darwin’s theory produces should not be understood in a pejorative, but rather in a literal sense. The theory of evolution, in effect, divests nature of its magical character and begins to explain it in terms of natural selection, according it, in the process a new and more intense attraction. In the present work, the metaphysical implications of this new vision of the world are analyzed through the eyes of its discoverer.

Fresadora C.N.C. de tres ejes

Tras la aparición de Arduino en el año 2002, emergió un fuerte movimiento concienciado con las plataformas libres, tanto en software como en hardware. Este movimiento junto con la filosofía del hágalo usted mismo (Do It Yourself) hizo que surgieran un sin fin de proyectos de todas las índoles, desde proyectos simples, como robots cartesianos, hasta proyecto más serios, como puede ser una máquina de control numérico. Todo esto es posible ya que junto con Arduino, han surgido infinidad de complementos y sensores asociados, fáciles de conseguir, baratos y que hacen que casi cualquier proyecto sea fácil de llevar a cabo y además económicamente viable. Lo que el autor de este proyecto fin de grado quiere hacer llegar al lector, es que un proyecto tan abrumador como puede ser una máquina de control numérico, puede ser perfectamente factible gracias a las bondades de una placa de un precio ínfimo y el ecosistema generado en torno a él.

Distribution of Healthcare resources II.Study and Comparison of a Linear Programming Problem and its Dual. Resolution and Evaluation of a Practical Case and its Programming using Excel and Win QSB.

[EN]This research had as primary objective to model different types of problems using linear programming and apply different methods so as to find an adequate solution to them. To achieve this objective, a linear programming problem and its dual were studied and compared. For that, linear programming techniques were provided and an introduction of the duality theory was given, analyzing the dual problem and the duality theorems. Then, a general economic interpretation was given and different optimal dual variables like shadow prices were studied through the next practical case: An aesthetic surgery hospital wanted to organize its monthly waiting list of four types of surgeries to maximize its daily income. To solve this practical case, we modelled the linear programming problem following the relationships between the primal problem and its dual. Additionally, we solved the dual problem graphically, and then we found the optimal solution of the practical case posed through its dual, following the different theorems of the duality theory. Moreover, how Complementary Slackness can help to solve linear programming problems was studied. To facilitate the solution Solver application of Excel and Win QSB programme were used.
