Lascia Ch\u27io Pianga

Recitative: [Italian] Armida, dispietata colla forza d’abisso rapimmi al caro Ciel di miei contenti, e qui con duoloeterno viva mi tiene in tormento d’inferno. Signor! Ah! Per pieta, lascia mi piangere. [German] Armida, Mitleidlose! In den Abgrund des Jammers versanken ewig mir des Lebens Freuden, und hier mit ew’gen Qualen halt mich gefesselt die grause Nacht der Holle. O Herr! Ach, hab’ Erbarmen und lass mich weinen. [English] Armida, cruel fortune with a power inhuman withdraw my heart from Heav’n and my contentment And here with grief eternal Living it holds me in torment most infernal O Lord! In pity hear me tears will relieve me. Aria: [Italian] Lascia ch’io piaga la dura sorte e che sospiri la liberta; e che sospiri, e che sospiri, la liberta! Lascia ch’io pianga la dura sorte e che sospiri la liberta. Il duol infranga queste ritorte de miei martiri sol per pieta, Si, de’ miei martiri sol per pieta. [French] Peine cruelle! Douleur mortelle!Mon Coeur t’appelle, O liberte.Par les a laremsE par le larmesCe coeur est brise! Peine cruelle!Douleur mertelle!Mon coeur t’apelle, O liberte!Quand se decahineSur moi la haineTrop inhumaineOh Dieu, brisez me chaine,Brisez me chaine,Dans votre bonte! [German] Laa mich mit Tranen mein Loos beklagen,Ketten zu tragen, welch’ hartes Geschick!Ketten zu tragen,Ketten zu tragen, welch’ hartes Geschick!Lass mit Thranen mein Loos beklagen,Ketten su tragen walch’ hartes Geschick!Ach, nut im Tode fins’ ich Erbarmen,Er giebt mir Armen die Ruh’ zuruck, ja,er giebt mir Armen die Ruh’ zuruck. [English] Here let my tears flow!Let hope my soul know,My heart is longingFor Liberty,My heart is longing,My heart is longingFor Liberty.Here let my tears flowLet hope my soul knowMy heart is longingFor Liberty!Assuage the sorrow to chains belongingO, great tomorrowThat I may be free,O, great tomorrowThat I may be free

Isotopic investigation of diet and residential mobility in the Neolithic of the Lower Rhine Basin

Multiple isotopic systems (C, N, O, S, Sr, Pb) are applied to investigate diet and mobility amongst the Middle Neolithic populations at Schipluiden and Swifterbant (Netherlands). A review of carbon and nitrogen isotope analyses of European Mesolithic and Neolithic populations shows a shift in diet from the Mesolithic to the Neolithic, but also great variety in Neolithic diets, several of which incorporate fish. At Swifterbant (c.4300—4000 BC) the population had a diet largely based on terrestrial and freshwater resources, despite proximity to tidal waters. Only one individual (of 10) showed evidence for migration. In contrast at Schipluiden (c.3600—3400 BC) there were migrants who had a diet lower in marine resources than those without evidence for migration. The faunal spectrum and isotopic similarities with sites in the Iron Gates Gorge suggest that sturgeon may have been important. There is some evidence that migrants at Schipluiden were not accorded the formal burial given to locally born people

Run-time detection of faults in autonomous mobile robots based on the comparison of simulated and real robot behaviour

© 2014 IEEE. This paper presents a novel approach to the run-time detection of faults in autonomous mobile robots, based on simulated predictions of real robot behaviour. We show that although simulation can be used to predict real robot behaviour, drift between simulation and reality occurs over time due to the reality gap. This necessitates periodic reinitialisation of the simulation to reduce false positives. Using a simple obstacle avoidance controller afflicted with partial motor failure, we show that selecting the length of this reinitialisation time period is non-trivial, and that there exists a trade-off between minimising drift and the ability to detect the presence of faults

A large area detector for neutrons between 2 and 100 MeV

A neutron detector sensitive from 2 to 100 MeV is described. The detector is designed for high altitude balloon flight to measure the flux, energy and direction of albedo neutrons from the earth and to search for solar neutrons. A neutron scatter from a proton is required in each of two liquid scintillator tanks spaced 1 meter apart. The energy of the recoil proton in the first tank is obtained from pulse height analysis of the scintillator output. The energy of the recoil neutron is obtained from its time of flight between the tanks. The detector has been calibrated with 15.3 MeV neutrons and mu mesons. The minimum detectable flux is 10(-4) neutron/sq cm/sec at a counting rate of one per minute; the energy resolution is 12% at 15 MeV and 30% at 100 MeV. The angle between the incoming neutron and the recoil neutron is measured to + or - 10 deg
