Using the Analytic Hierarchy Process (AHP) in Evaluating the Decision of Moving to a Manufacturing Process Based Upon Continuous 5 Axes CNC Machine-t…
2016
Abstract This paper represents the second part of the work described in the paper with the title “Decision-making tool for moving from 3-axes to 5-axes CNC machine-tool”. The problem of using either 3 axes CNC machine-tools or 5 axes CNC machine tools was presented in the first part, together with a fuzzy logic based decision support tool. This time, an AHP approach is used in order to evaluate the decision of moving to a manufacturing process based upon 5 axes machine tools. Three variants were taken into consideration and analysed. The consistency of the proposed approach was evaluated and a sensitivity analysis was also introduced.

The aim of the present thesis is twofold: first, it gives an overview onice climbers’ activity, based on an enactive empirical research program of cognitive anthropology, while developing a technological research program toevaluate appropriation situations and perspectives for design. The first part of this work focuses on the link between innovation and practice while identifying the relationship between the climbers and the technical object in order to build a technological research program focusing on the appropriation of objects. The second part is an epistemic work inculding two steps: a) to produce knowledge on the mediation role of ice axes for novice climbers and b) to develop desig…

Palermo vs Panormus
2019
Quando nel settimo secolo a.C. i coloni fenici arrivarono dal mare nel Golfo di Palermo (anticipato, a grande distanza, dalla peculiare forma del Monte Pellegrino), certamente capirono come la valle che si apriva davanti a loro (la cosiddetto Conca d'oro) - ricca di vegetazione, attraversata da corsi d’acqua e protetta dal micidiale vento di Nord / Ovest, il Maestrale - fosse il posto giusto per fondare una nuova città. Le generazioni seguenti continuarono a costruire la città sul promontorio, mantenendo e consolidando l'orientamento Est / Ovest e affidando all'asse principale (il Cassaro) il ruolo, non secondario e fortemente simbolico, di collegare le montagne e il mare attraverso la citt…
Drift of the Earth’s Principal Axes of Inertia from GRACE and Satellite Laser Ranging Data
2020
The location of the Earth’s principal axes of inertia is a foundation for all the theories and solutions of its rotation, and thus has a broad effect on many fields, including astronomy, geodesy, and satellite-based positioning and navigation systems. That location is determined by the second-degree Stokes coefficients of the geopotential. Accurate solutions for those coefficients were limited to the stationary case for many years, but the situation improved with the accomplishment of Gravity Recovery and Climate Experiment (GRACE), and nowadays several solutions for the time-varying geopotential have been derived based on gravity and satellite laser ranging data, with time resolutions reac…
ENTREACTO / ENTR?ACTE Un film / A Film Chopin y los Sand, amor a cuatro bandas. Aproximación a la esfera privada de Fryderyk Chopin a partir de la pe…

Two centuries later, the legend Chopin-Sand continues to supply the collective imaginary with vague readings, where historical truthfulness, let alone musical truth, is often contingent on the literary. The much discussed and bellicose romance between the Polish composer and the French novelist, George Sand, tends to some reductionism and evades an obvious reality: Fryderyk Chopin meets George Sand when she was already the mother of two children. This circumstance suggests reformulating certain romantic stereotypes. Jerzy Antczak?s biographical film Pragnienie Mi?o?ci (Chopin: Desire for Love, 2002) does not overlook this detail and makes it one of its narrative axes. The relationship betwe…
