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
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
Los agentes de emigracion de Burdeos
No full textÀ partir de la mise en place d’une législation sous le Second Empire pour accorder des autorisations aux agents d’émigration et surveiller leurs activités, le nombre de demandes d’exercer ce métier est demeuré stable au cours de la seconde moitié du XIXe siècle, malgré l’accroissement des départs. Le présent chapitre s’intéresse aux cas qui ont motivé les enquêtes de police plus poussées sur Bordeaux. Ce sont les parcours de vie qui seront étudiés ici, les agents Lagoanère, Lévy et Depas faisant l’objet de graves accusations qui illustrent la vulnérabilité des émigrants. Puis, dans les années 1870 Jules Mortier est choisi par les autorités étrangères pour favoriser l’émigration au Pérou. Après 1880, l’agence Colson occupe la place bordelaise en particulier pour envoyer des migrants au Chili. À la fin du siècle, les procédures sont allégées et les dossiers des agents d’émigration réduits aux autorisations d’exercer et aux remboursements des cautionnements.From the introduction of legislation during the Second Empire to grant authorisations to emigration agents and monitor their activities, the number of applications to practise remained stable during the second half of the 19th century, despite the increase in departures. This chapter examines the cases that prompted further police investigations. It is the life courses that will be studied here, with agents Lagoanère, Lévy and Depas facing serious charges that illustrate the vulnerability of emigrants. Then, in the 1870s, Jules Mortier was chosen by foreign authorities to encourage emigration to Peru. After 1880, the Colson agency took over the Bordeaux area, in particular to send migrants to Chile. At the end of the century, procedures were streamlined and the files of emigration agents were reduced to authorisations to practice and the reimbursement of guarantees.A partir de la legislación del Segundo Imperio con Napoleón III, para conceder autorizaciones a los agentes de emigración y controlar sus actividades, el número de solicitudes se mantuvo estable durante la segunda mitad del siglo XIX, a pesar del aumento de las salidas. En este capítulo se examinan los casos que dieron lugar a investigaciones policiales desde Burdeos. Se examinan aquí las biografías de los agentes marítimos Lagoanère, Lévy y Depas enfrentados a graves acusaciones, que ilustran la vulnerabilidad de los emigrantes. Luego, en la década de 1870, Jules Mortier fue elegido por las autoridades peruanas para fomentar la migración a Lima. Después de 1880, la agencia Colson se dedicó a enviar migrantes a Chile desde Burdeos. A finales del siglo, los tramites se simplificaron y los documentos de los agentes de emigración se limitaron a autorizaciones para ejercer y a devolución de fianzas

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
Isabelle/DOF: Design and Implementation
No full textThis is the author accepted manuscript. The final version is available from Springer Verlag via the DOI in this record17th International Conference, SEFM 2019
Oslo, Norway, September 18–20, 2019DOF is a novel framework for defining ontologies and enforcing them during document development and evolution. A major goal of DOF is the integrated development of formal certification documents (e. g., for Common Criteria or CENELEC 50128) that require consistency across both formal and informal arguments. To support a consistent development of formal and informal parts of a document, we provide Isabelle/DOF, an implementation of DOF on top of the formal methods framework Isabelle/HOL. A particular emphasis is put on a deep integration into Isabelleâs IDE, which allows for smooth ontology development as well as immediate ontological feedback during the editing of a document. In this paper, we give an in-depth presentation of the design concepts of DOFâs Ontology Definition Language (ODL) and key aspects of the technology of its implementation. Isabelle/DOF is the first ontology language supporting machine-checked links between the formal and informal parts in an LCF-style interactive theorem proving environment. Sufficiently annotated, large documents can easily be developed collabo- ratively, while ensuring their consistency, and the impact of changes (in the formal and the semi-formal content) is tracked automatically.IRT SystemX, Paris-Saclay, Franc
