Arthropleura is a genus of giant myriapods that ranged from the early Carboniferous to Early Permian, with some individuals attaining lengths >2 m. Although most known fossils are disarticulated and occur primarily in late (Pennsylvanian) strata, we report here partially articulated remains Stainmore Formation (Serpukhovian; Pendleian) Northumberland Basin northern England. This 76 × 36 cm s...

abstract: degumming and neutralization processes are two essential stages carried out on crude edible oils in order to remove some unwanted impurities namely gums and free fatty acids. in this research study two popular less expensive commercial oils that are consumed to a great extent namely soyabean and sunflower seed oils are selected and subjected to both degumming and neutralization proces...

in quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. the failure mode in these two directions is usually different. a great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics....

background: business process management systems (bpm) can automate all processes in an organization. these systems provide the possibility of identifying, modeling, deploying, implementing, function managing, integrating with other information systems, monitoring and improving an organization's business processes in a standard form. as far as the authors know, no related research has been ...

Modeling and Analysis Alexandre David November 18, 1998 Introduction It is our experience with model-checkers such asUppaal [1] that a large part of the total time, in most of the case studies, is spent on constructing the system model. This has lead to a strong demand for a modeling language with features supporting abstractions such as hierarchical descriptions of models. There have been seve...

Abstract Our understanding of the stratigraphic expression astronomically driven climate-change cycles in Milankovitch frequency band has improved significantly recent decades. However, several aspects have been little studied to date, such as nature climatically regulated environmental processes that ultimately control cyclic sedimentation. Similarly, relatively is known about successions accu...

abstract: in this paper, an exergy analysis approach is proposed for optimal design of distillation column by using simulated annealing algorithm. first, the simulation of a distillation column was performed by using the shortcut results and irreversibility in each tray was obtained. the area beneath the exergy loss profile was used as irreversibility index in the whole column. then, first opti...

a new method is developed for a fast identification of the stability situation of industrial processes. the proposed method includes two factor ratios of the control constants for the upper and lower control limits to process these constants. an indication ratio is then defined as the ratio of the maximum data range value to the difference between the maximum and average values for individual d...
