El proyecto fin de carrera de herramienta de apoyo a la docencia en Sistemas Operativos quiere ayudar al alumno a entender el funcionamiento de un planificador a corto plazo. Lo hace mediante una representación gráfica de procesos que ocupan o el procesador o distintas unidades de entrada/salida mientras transcurre el tiempo. El tiempo está dividido en ciclos de reloj de un procesador, a lo que a continuación se referirá como unidades de tiempo. Los procesos están definidos por su nombre, la instante de entrada que entran al sistema, su prioridad y la secuencia de unidades de tiempo en el procesador y unidades de entrada/salida que necesitan para terminar su trabajo. El alumno puede configurar el sistema a su gusto en cuanto al número y comportamiento de las unidades de entrada/salida. Puede definir que una unidad solo permita acceso exclusivo a los procesos, es decir que solo un proceso puede ocuparla simultáneamente, o que permita el acceso múltiple a sus recursos. El alumno puede construir un planificador a corto plazo propio, integrarlo en el sistema y ver cómo se comporta. Se debe usar la interfaz Java proporcionada para su construcción. La aplicación muestra datos estadísticos como por ejemplo la eficiencia del sistema (el tiempo activo de la CPU dividido por el tiempo total de la simulación), tiempos de espera de los procesos, etc. Se calcula después de cada unidad de tiempo para que el alumno pueda ver el momento exacto donde la simulación tomó un giro inesperado. La aplicación está compuesta por un motor de simulación que contiene toda la lógica y un conjunto de clases que forman la interfaz gráfica que se presenta al usuario. Estos dos componentes pueden ser reemplazados siempre y cuando se mantenga la definición de sus conectores igual. La aplicación la he hecho de manejo muy simple e interfaz fácil de comprender para que el alumno pueda dedicar todo su tiempo a probar distintas configuraciones y situaciones y así entender mejor la asignatura. ABSTRACT. The project is called “Tool to Support Teaching of the Subject Operating Systems” and is an application that aims to help students understand on a deeper level the inner workings of how an operating system handles multiple processes in need of CPU time by the means of a short-term planning algorithm. It does so with a graphical representation of the processes that occupy the CPU and different input/output devices as time passes by. Time is divided in CPU cycles, from now on referred to as time units. The processes are defined by their name, the moment they enter the system, their priority and the sequence of time units they need to finish their job. The student can configure the system by changing the number and behavior of the input/output devices. He or she can define whether a device should only allow exclusive access, i.e. only one process can occupy it at any given time, or if it should allow multiple processes to access its resources. The student can build a planning algorithm of his or her own and easily integrate it into the system to see how it behaves. The provided Java interface and the programming language Java should be used to build it. The application shows statistical data, e.g. the efficiency of the system (active CPU time divided by total simulation time) and time spent by the processes waiting in queues. The data are calculated after passing each time unit in order for the student to see the exact moment where the simulation took an unexpected turn. The application is comprised of a simulation motor, which handles all the logic, and a set of classes, which is the graphical user interface. These two parts can be replaced individually if the definition of the connecting interfaces stays the same. I have made the application to be very easy to use and with an easy to understand user interface so the student can spend all of his or her time trying out different configurations and scenarios in order to understand the subject better.

The multi-dimensional classification problem is a generalisation of the recently-popularised task of multi-label classification, where each data instance is associated with multiple class variables. There has been relatively little research carried out specific to multi-dimensional classification and, although one of the core goals is similar (modelling dependencies among classes), there are important differences; namely a higher number of possible classifications. In this paper we present method for multi-dimensional classification, drawing from the most relevant multi-label research, and combining it with important novel developments. Using a fast method to model the conditional dependence between class variables, we form super-class partitions and use them to build multi-dimensional learners, learning each super-class as an ordinary class, and thus explicitly modelling class dependencies. Additionally, we present a mechanism to deal with the many class values inherent to super-classes, and thus make learning efficient. To investigate the effectiveness of this approach we carry out an empirical evaluation on a range of multi-dimensional datasets, under different evaluation metrics, and in comparison with high-performing existing multi-dimensional approaches from the literature. Analysis of results shows that our approach offers important performance gains over competing methods, while also exhibiting tractable running time.

Contributing to the acquisition of professional creativity and teamwork skills has been a special challenge for some of the subjects taught at the Technical University of Madrid (UPM), and this has been a starting point for the work described in this paper. Some professors have intuited that the use of cooperative classrooms could facilitate the acquisition of these skills. We describe the new methodologies applied within cooperative classrooms by some professors, and present the procedure for measuring students’ perception of their own learning outcomes, skill improvements, and overall satisfaction with the use of this kind of classroom. For this project, 250 students enrolled in several subjects answered a questionnaire. The featuresof thesubjectsinvolved intheproject arewidely disparate. We present the results of the statistical analysis with special emphasis on creativity and teamwork skills, and we conclude that the use of cooperative classroom has a positive influence on the acquisition of these skills. This work has the added value of being the first analysis of student perception of the use of cooperative classroom in the acquisition of creativity and teamwork skills.
