Stage boundaries, global stratigraphy, and the time scale: towards a simplification

2004

International audience; This paper examines four facets of stratigraphic terminology and usage considered faulty and proposes corrective measures. The four perfectible areas are: (1) The system of dual nomenclature requiring discrete terminologies for the superpositional and temporal aspects of rock units. (2) The premise that a GSSP establishes the base of a stage as being coincident with the top of the preceding stage rather than simply defining it as the boundary between stages. (3) The rejection of supplementary (auxiliary) sections that would broaden the knowledge of a GSSP and enlarge the area in which it is easily usable. (4) The current dual system of nomenclature for Precambrian an…

Proposal for the Thuoux section as a candidate for the GSSP of the base of the Oxfordian stage.

2012

20 pages; International audience; The Thuoux section, located in South-Eastern Basin of France (coordinates: 44°30'55"E; 5°42'25"N), is a section that satisfies numerous demanding criteria as reference section (GSSP) for the base of the Oxfordian stage. Sedimentation was continuous in that the abundant ammonitic fauna yields no detectable hiatuses. The stratigraphic boundary is located between the Lamberti Zone and the Mariae Zone or more precisely between the Paucicostatum horizon (MARCHAND, 1979) and the Thuouxensis horizon (FORTWENGLER & MARCHAND, 1994a). In this section, there is a perfect mixing bet-ween Boreal ammonites (Cardioceratinae) whose species are used as stratigraphic markers…

Integrated stratigraphy of the potential candidate Oxfordian GSSP at Thuoux and Saint-Pierre d'Argençon (France).

2013

5 pages; International audience; The Thuoux and Saint-Pierre d'Argençon sections (Subalpine Basin, southeastern France) are proposed as a potential GSSP candidate for the Callovian-Oxfordian boundary. Several aspects of stratigraphy that have recently been applied in the two selected sections are discussed, including ammonite and nannofossil biostratigraphy, palynology, physical stratigraphy, and cyclostratigraphy.

Late Carnian-Early Norian ammonoids from the GSSP candidate section Pizzo Mondello (Sicani mountain, Sicily).

2012

A small collection of ammonoids from the Upper Triassic Scillato Formation at Pizzo Mondello (Agrigento, Sicily) is studied. The specimens were collected in a framework of a project aimed at providing an integrated high-resolution bio-chronostratigraphic support to the Upper Carnian-Norian magnetostratigraphic scale defined at this site, that is located in an historical area from which G.G. Gemmellaro collected the Upper Triassic of ammonoids monographed at the beginning of the XX century. The specimens from Pizzo Mondello were bed-by-bed sampled and represent the first collection of Upper Triassic ammonoids described from Sicily since Gemmellaro time. Quite several levels of the Pizzo Mond…

The Monte San Nicola section (Sicily) revisited: A potential unit-stratotype of the Gelasian Stage

2022

The Monte San Nicola area (Southern Sicily) offers a spectacular exposure of open-marine sediments that were employed in 1998 for defining the Global Stratotype Section and Point (GSSP) of the Gelasian Stage (Upper Pliocene). After the lowering of the Pliocene/Pleistocene boundary to ca. 2.6 Ma in 2010, the Gelasian GSSP has been redefined as the base of both the Pleistocene Series and the Quaternary Period, which increased its importance and visibility within the scientific community. However, documentation on the Monte San Nicola reference section is still sparse. In the light of its renewed status, we decided to undertake a complete revision of the Gelasian Stage in its type area, in ord…

Evaluation of OSA API's for 3rd party developers of Telco-services

2002

Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad Changes in business models introduce new actors to the telecom business. A set of new demands occurs and to handle this, a technical enabler like OSA is needed. Telenor R&D, which often provides Telco services in research projects, must form an opinion concerning this framework. Thus an evaluation of OSA is inquired. This thesis presents an introduction and evaluations of the OSA framework, further, a closer look at two of the OSA API’s (User Status and Terminal Capabilities) are made. To enhance the evaluation, Youngster has been utilized as an example of where the OSA framework can be used. An impl…

Veien fra Bee-Bot til Scratch : En casestudie om hvilke kunnskaper elevene sitter igjen med etter å ha prøvd to ulike programmeringsverktøy

2019

Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2019 The way from Bee-Bot to Scratchis a case study that looks at what competencies the pupilsmanage to pass from anobject programminglanuageto a computer-based programming language.Because programming comes under the core elements of mathematics in the new curriculum that is initiated in the autumn of 2020, I have chosen this research question: "Can the pupils' programming knowledgefrom Bee-Bot be transferred to Scratch in a mathematics session,focusing on computational thinkingand creativity?" The study therefore focusesat howmuch of the various topicsemerge and which competences the pupils manage to pass on from the programm…

A real time operating system for embedded platforms

2004

Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad SDL (Specification and Description Language) is today widely used for description and development of complex systems. One of the major benefits of SDL is the possibility to graphically describe a complex system, as well as the capability to analyze the system before implementation. This thesis evaluates SDL as a formal description language for use in an embedded platform. To be able to map the properties and behaviour of an SDL system into a programming language, a Real Time Operating System (RTOS) must be used. We will evaluate all properties of SDL to get a overview of which properties can be mappe…
