Optimal airline seat inventory control for multi‐leg flights
2004
Airline seat inventory control is about “selling the right seats to the right people at the right time”. In this paper, the problem of determining optimal booking policy for multiple fare classes in a pool of identical seats for multi‐leg flights is considered. During the time prior to departure of a multi‐leg flight, decisions must be made concerning the allocation of reserved seats to passengers requesting space on the full or partial spans of the flight. It will be noted that in the case of multi‐leg flights the long‐haul passengers are often unable to obtain seats because the shorter‐haul passengers block them. For large commercial airlines, efficiently setting and updating seat allocat…
Approximation of Measurement Results of “Emergency” Signal Reception Probability
2017
Abstract The intended aim of this article is to present approximation results of the exemplary measurements of EMERGENCY signal reception probability. The probability is under-stood as a distance function between the aircraft and a ground-based system under established conditions. The measurements were approximated using the properties of logistic functions. This probability, as a distance function, enables to determine the range of the EMERGENCY signal for a pre-set confidence level.

La alimentación en los viajes espaciales tripulados: desde el Programa Gemini hasta la ISS/Shuttle
2014
Los alimentos espaciales han tenido una gran importancia en el desarrollo de las misiones espaciales tripuladas ya que constituyen la única fuente de energía y nutrientes para el ser humano fuera del planeta Tierra. Dichos alimentos han experimentado una gran evolución desde el inicio del Programa Mercury hasta las actuales misiones a la International Space Station (ISS). En un primer momento eran diseñados para ofrecer una gran densidad energética y nutritiva y actualmente se da prioridad a las características organolépticas y psicológicas, ya que contribuyen a un mayor consumo y un mejor estado nutricional de los astronautas. El objetivo del presente estudio es hacer un análisis retrospec…

Factors affecting flavor perception in space: Does the spacecraft environment influence food intake by astronauts?
2020
International audience; The intention to send a crewed mission to Mars involves a huge amount of planning to ensure a safe and successful mission. Providing adequate amounts of food for the crew is a major task, but 20 years of feeding astronauts on the International Space Station (ISS) have resulted in a good knowledge base. A crucial observation from the ISS is that astronauts typically consume only 80% of their daily calorie requirements when in space. This is despite daily exercise regimes that keep energy usage at very similar levels to those found on Earth. This calorie deficit seems to have little effect on astronauts who spend up to 12 months on the ISS, but given that a mission to …
Quattro diagnosi sul Florario di Francesco Buti
2009
Il messaggio etico dei testi di Francesco Buti per i "Fiori" di Girolamo Kapsperger (villanelle a 1,2,3,4 voci e Bc. del 1632) e la ricercata semplicità della musica giustificano la scelta anacronistica e stilisticamente inappropriata della titolazione di genere scelta da Kapsperger o dall’editore Masotti. Il termine villanella allude in questo caso a un giardino in cui i fiori formano un mazzetto di allegorie per il buon cristiano. Più specificamente i soggetti riguardano i miti classici collegati ai vegetali, ai quali si ispira l’autore per riprendere le leggende sull’origine dal sangue o dal latte degli dei, da cui nacquero per metamorfosi il gelsomino, la viola, la rosa, l’amaranto, l’a…
La cantata a Palermo fra Sei e Settecento: il caso dei Gesuiti
2017
Il contributo esamina la diffusione a Palermo tra Sei e Settecento del genere della cantata, nelle molteplici accezioni che tale termine racchiude: cantata celebrativa, cantata spirituale, cantata da camera. In particolare si dà rilievo all’attività di committenza dei gesuiti e al repertorio delle cantate in latino (solo di rado in italiano) che tra XVII e XVIII secolo venivano eseguite in occasione delle cerimonie per laurea che avevano luogo nel collegio della compagnia.
