Cut-elimination, substitution and normalisation
No full textDate of Acceptance: 01/2015We present a proof (of the main parts of which there is a formal version, checked with the Isabelle proof assistant) that, for a G3-style calculus covering all of intuitionistic zero-order logic, with an associated term calculus, and with a particular strongly normalising and confluent system of cut-reduction rules, every reduction step has, as its natural deduction translation, a sequence of zero or more reduction steps (detour reductions, permutation reductions or simplifications). This complements and (we believe) clarifies earlier work by (e.g.) Zucker and Pottinger on a question raised in 1971 by Kreisel.Peer reviewe
I remember teaching English at Seabrook
No full textIn this "I remember" memoir, Isabell Waugh, a former teacher at Seabrook, compares and constrasts the different groups of students she taught. She remembers that native-born American teenagers tended to be more concerned with athletics and social activities, than academic matters. In comparison, Estonian and Japanese parents did not tolerate low academic performance, so students from the two groups often competed intensely with each other for academic achievement and recognition. Isabelle recalls that the Estonians were, in general, more sophisticated and better educated. Most of the children knew 3-5 languages, and were more advanced in math and science. She sensed that some Estonian parents felt that their homes at Seabrook were temporary, and that they would be returning to Estonia at some point. The Seabrook Educational and Cultural Center has been soliciting current and past residents of Seabrook Farms for an "I remember" project. Residents are asked to create narratives regarding their experiences at Seabrook Farms. These memories help preserve the history and multi-cultural heritage of Seabrook Farms
Polariton laser using single micropillar GaAs-GaAlAs semiconductor cavities
No full textPolariton lasing is demonstrated on the zero-dimensional states of single GaAs=GaAlAs micropillar
cavities. Under nonresonant excitation, the measured polariton ground-state occupancy is found as large
as 10^4. Changing the spatial excitation conditions, competition between several polariton lasing modes is
observed, ruling out Bose-Einstein condensation. When the polariton state occupancy increases, the
emission blueshift is the signature of self-interaction within the half-light half-matter polariton lasing
mode
Isabelle Bell to Susan Niemcewicz, December 23, 1800
No full textIsabelle Bell wrote to Susan U. Niemcewicz in Elizabethtown, New Jersey. Bell expressed her disappointment in not receiving a line from Susan. She sent Bell Lucretia Rephans subscription epistle, but Susan refrained from writing a letter to her. Bell did not execute any of Susan’s commissions in New York because her time there was short. Miss Resham heard that Mr. B Livingston told his sister, Mrs. J. Livingston that he would offer Bell a salary to live in his house and take charge of his children’s education. Asked if Susan what she thought of her being an author and if Susan would subscribe to a small volume that may have the good fortune to rival the poems of the immortal Scarron.https://digitalcommons.kean.edu/lhc_1800s/1143/thumbnail.jp

Formalization of Isabelle Meta Logic in NuPRL
No full textNuPRL and Isabelle are two general purpose theorem provers. Both of them are based on a version of Constructive Higher Order Type Theory. In an earlier work the author has proposed an informal semantics of Isabelle Meta Logic in an extension of NuPRL Type Theory. An automated converter, based on this semantics, has been developed, that translates Isabelle theorem statements into NuPRL. This work presents a formalization of the above semantics in NuPRL. It starts with a deep embedding of Isabelle type and term syntax into NuPRL Constructive Type Theory. Next, two internal NuPRL functions are defined. One of them maps Isabelle types into NuPRL types and the other maps Isabelle terms into elements of appropriate NuPRL types. These two functions provide an interpretation of Isabelle in NuPRL. Finally, interpretations of all Isabelle Meta Logic rules are proven as theorems in some classical extension of NuPRL Type Theory. This formalization is aimed to provide a more secure foundation for the interaction between two systems
Security modeling and correctness proof using Specware and Isabelle
No full textSecurity modeling is the foundation to formal verification which is a core requirement for high assurance systems. This thesis explores how security models can be built in a simple and expressive manner using the Metaslang specification language in Specware. The models are subsequently translated, via the Specware to Isabelle Interface, to be proven for correctness in Isabelle which is a generic, interactive theorem proving environment. It is found that the translation between Specware and Isabelle is almost seamless and there is much potential in the use of Isabelle/HOL to discharge proof obligations that arise in developing Specware specifications, although the actual proving requires substantial knowledge and experience in logical calculus.Approved for public release; distribution is unlimited.Outstanding ThesisSingapore ST Electronics Ltd. author (civilian).http://archive.org/details/securitymodeling10945383
Semiconductor's quantum dot source for the nanophotonic and the quantum information at the telecommunication's wavelengths
No full textLe siècle dernier a vu l'accomplissement de la mécanique quantique, du traitement de l'information etde l'optique intégrée. Aujourd'hui, ces trois domaines se rencontrent pour donner naissance à l'optiqueintégrée pour les communications quantiques. Un des enjeux aujourd'hui dans ce domaine est ledéveloppement de sources de photons unique aux longueurs d’onde des télécommunications fibrés.Durant ce travail de thèse les émetteurs étudiés sont des boîtes quantiques d’InAsP épitaxiés parEPVOM (Epitaxie en Phase Vapeur aux OrganoMétalliques). On démontrera que ces objets uniquessont capables d’émettre des états quantiques de la lumière grâce à une expérience de dégroupement dephotons. De plus la spectroscopie de ces objets sera déduite des études résolues en temps. Lapossibilité d’intégrer ces objets au sein de nanocavité de taille ultime permet de modifier leur tauxd’émission spontanée, ainsi les résultats obtenus grâce aux cavités métalliques permettent d’observerune accélération de l’émission spontanée sur une large bande spectrale. Finalement il a été mis enévidence une forte modification de l’émission d’un ensemble de boîtes quantiques entre 4K et 300K,en utilisant une technique originale basé sur l’effet laser.The last century saw the advent of quantum mechanics, information processing and integrated optics.These fields lead to the integrated optics for quantum communication. One of the challenges is thedevelopment of single photon sources operating at fiber’s telecommunication wavelength. In this workwe use quantum dots growth by MOVPE (MetalOrganic Vapour Phase Epitaxy). We demonstratethese emitters can generate some quantum state of light thanks to the antibunching experiment.Moreover the spectroscopy of these objects will be deducted by the time resolved spectroscopy. Thepossibility to integrate these sources in ultimate’s size cavity permits to modify the spontaneous rateemission, so the result obtain with metallic cavity permit to observe an acceleration of the spontaneousemission on a wide spectral band. Finally a strong emission modification of the quantum dot’sensemble between 4K and 300K will be presented by using an original way based on the laser effect
