The Ossa-Morena Zone (OMZ), SW Iberia, has numerous Lower Carboniferous compositionally zoned plutons that formed in a Variscan intra-orogenic extensional setting. This magmatism shows wide compositional variation comprising alkaline, transitional, and calc-alkaline suites. suite was produced by hybridization of alkaline magmas with felsic melts generated crustal anatexis related to the intrusi...
Most database applications manage time-referenced, or temporal, data. Temporal data management is difficult when using conventional database technology, and many contributions have been made for how to better model, store, and query temporal data. Temporal aggregation illustrates well the problems associated with the management of temporal data. Indeed, temporal aggregation is complex and among...
In this article, we describe data on (1) compositions for both as-cast and heat treated specimens were summarized in Table 1; (2) the determined enthalpy of mixing of liquid phase is listed in Table 2; (3) thermodynamic database of the Co-Pr system in TDB format for the research articled entitle Chemical partitioning for the Co-Pr system: First-principles, experiments and energetic calculations...
In this paper we survey the use of different AI methods for algorithmic composition, present their advantages and disadvantages, discuss some important general issues and propose desirable future prospects
This paper presents a framework being developed to clarify discussion of algorithmic musical processes. We will firstly present some of the current terminological problems and then discuss related research and background concepts. Following this, two principal attributes that enable intuitive comparison of algorithmic compositional processes will be defined in detail. The framework will then be...
We highlight that the off-stoichiometric compositional variation is a simply effective method to improve the power density of LiFe0.6Mn0.4PO4. This strategy does not require a supplementary separate coating and is likely applicable to other compositions given the feasibility of the method.
Because natural organisms are a part of the factors constituting the ecosystem for each organism, it is important to clarify both physical and biological exploitable factors to determine species compositions which exist in that ecosystem. The variation in factors which constitute an ecosystem makes up the variation in species composition. At the same time, each species will interact and will ma...
Cerro El Toro, a Pliocene scoria cone that carried abundant lower crust xenoliths to the surface, is located in Mesa Central (MC), Mexico, where mafic alkalic intra-plate volcanism has occurred since early Miocene (end of Sierra Madre Occidental volcanism). Early studies Toro showed feldspathic granulite equilibrated at P = 0.9–1.4 GPa and T 900−1100°C under anhydrous conditions (ternary feldsp...
