Building a Generic Date-Time Framework - an Experience Report Using C++ Templates
Building a Generic Date-Time Framework - An Experience Report using C++ Templates Jeff Garland President & CTO CrystalClear Software, Inc [email protected] Copyright © CrystalClear Software, Inc 2001 Revised September 7, 2001 Abstract This paper describes the experiences of the author using C++ templates to build the Generic Date Time Library (GDTL). While there are many date-time representations available for C++, the libraries are often unsuitable for domains that need high precision, long epochs, infinity, specialized calendars, or custom clock sources. The GDTL is an attempt to use generic and template programming techniques to provide a single library that meets all these demands, as well as more typical date-time programming. To build a single library, templates are used in several roles: allow user replacement of underlying date and time representations, to factor out calendar interfaces, building range and composite types, and providing interface constraint enforcement. GDTL Background I became interested in this several years ago while helping to implement date-time classes to support a satellite control system. The software performed extensive time calculations and had to manage details such as leap second tables. Some calculations, needed precision down to microseconds. Other parts of the system needed to store millions of date-times in a database (each day) with only second-level precision. So forcing microsecond resolution for all times unnecessarily bloated the size of the database. In the end, the project had more than one time library. Some good components, but a host of project realities kept us from getting everything into a single library. In addition, traditional object-oriented design techniques did not directly support the required variations. -
Ecosystem Use by Indigenous People in an Oregon Coastal Landscape
3220 Donald B. Zobel, Department of Botany and Plant Pathology, Oregon State University, Corvallis, Oregon 97331- 2902 e-mail: [email protected] Ecosystem Use by Indigenous People in an Oregon Coastal Landscape Abstract Data regarding probable uses of biological materials by the indigenous people of the Salmon River-Cascade Head area of the Oregon coast were used to estimate the peoples use of various ecosystems near villages. Of 308 uses identified, 256 were attributable to a given species; 124 species were identified. All local ecosystems were important sources of organisms for the people, with no apparent concentration of highly used species in any particular ecosystem. One species was cultivated, one domesticated, and five acquired by trade. Four major plant resources, camas, yew, hazel, and beargrass, are not known from the Cascade Head landscape, but may have been available from elsewhere in village territory. House construction without use of cedar planks, as indicated by ethnographic records, may have resulted from the paucity of western redcedar in the Salmon River lowlands. The scarcity of several widely used taxa near coastal village sites, especially western redcedar, may have limited the wealth of this indigenous population, even on the resource-rich Oregon coast. Introduction Tillamook, who resided near Cascade Head on the north-central Oregon Coast, in an area where Indigenous people used resources primarily from information about historic and modern plant and the landscape in which they resided. The natural animal species distribution is unusually complete. distribution of resources governed the pattern and The list of taxa used was compared to historic richness of their lives. -

The Stratigraphic Architecture and Evolution of the Burdigalian Carbonate—Siliciclastic Sedimentary Systems of the Mut Basin, Turkey
The stratigraphic architecture and evolution of the Burdigalian carbonate—siliciclastic sedimentary systems of the Mut Basin, Turkey P. Bassanta,*, F.S.P. Van Buchema, A. Strasserb,N.Gfru¨rc aInstitut Franc¸ais du Pe´trole, Rueil-Malmaison, France bUniversity of Fribourg, Switzerland cIstanbul Technical University, Istanbul, Turkey Received 17 February 2003; received in revised form 18 November 2003; accepted 21 January 2004 Abstract This study describes the coeval development of the depositional environments in three areas across the Mut Basin (Southern Turkey) throughout the Late Burdigalian (early Miocene). Antecedent topography and rapid high-amplitude sea-level change are the main controlling factors on stratigraphic architecture and sediment type. Stratigraphic evidence is observed for two high- amplitude (100–150 m) sea-level cycles in the Late Burdigalian to Langhian. These cycles are interpreted to be eustatic in nature and driven by the long-term 400-Ka orbital eccentricity-cycle-changing ice volumes in the nascent Antarctic icecap. We propose that the Mut Basin is an exemplary case study area for guiding lithostratigraphic predictions in early Miocene shallow- marine carbonate and mixed environments elsewhere in the world. The Late Burdigalian in the Mut Basin was a time of relative tectonic quiescence, during which a complex relict basin topography was flooded by a rapid marine transgression. This area was chosen for study because it presents extraordinary large- scale 3D outcrops and a large diversity of depositional environments throughout the basin. Three study transects were constructed by combining stratal geometries and facies observations into a high-resolution sequence stratigraphic framework. 3346 m of section were logged, 400 thin sections were studied, and 145 biostratigraphic samples were analysed for nannoplankton dates (Bassant, P., 1999. -
