The main objective of a meteorological nowcasting system is to analyse and predict in ultra-short range those weather phenomena, which might be dangerous for life and property. The Hungarian Meteorological Service developed a nowcasting system (MEANDER), and its most computational intensive calculations have been parallelised by means of P-GRADE graphical programming environment. In this paper ...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

This article creates a generic grade concept that is a synthesis of wide range of terminologies linked with different paper types produced in paper mills. Nearly all paper mills and their system providers define the type and concepts of paper in different ways. The starting point in the grade concept is that it supports the diversified and reliable product profitability calculation as much as p...

This is a collaborative proposal between the Universities of Brighton and Kent. The team is ideally positioned to carry out the proposed programme of research, offering a combination of skills in diagrammatic reasoning, visual modelling, logic and automated reasoning, and tools for diagram manipulation and visualisation. The principal investigators have worked together for six years and have co...

Video recording is increasingly used in higher education settings to help students develop their oral presentation skills. However, little is known about the effect of video review for bringing about better high school student outcomes in oral presentation in formal (classroom) and informal (out-of-classroom) settings. Using a quasi-experimental design, this study investigated the effectiveness...

An 85 year old man presented with symptoms of dyspepsia and increase in stool frequency of two months duration. Upper endoscopy revealed an ulcer and the biopsy was interpreted as carcinoma with endocrine features. A formal distal gastrectomy was planned, but intraoperatively, because of the patient's condition, a wedge resection was performed. Histology revealed a neuroendocrine tumour (grade ...

8th graders gave complete falsification solutions 29% of the time, 10th graders, 42%, and 12th graders, 46%. When only the three familiar problems are considered, 8th graders gave complete falsification solutions 48% of the time, 10th graders, 62%, and 12th graders, 68%. A test for the difference between two proportions revealed that only the 12th grade selected this solution more frequently th...

In 2012 January, as part of the ongoing process of curriculum revision which began in 1994, the South African Depart of Education (DoE) introduced the Curriculum and Assessment Policy Statement (CAPS). The CAPS brought Euclidean geometry with its formal proof back into the compulsory mathematics curriculum. It also implied that all learners needed to perform at level 4 (Deduction: with formal p...
