5 Bench blasting is the most widely used method of production blasting in quarrying strip mining and construction excavation This involves drilling inclined vertical or horizontal blastholes in single or multiple row patterns to depths ranging from a few meters to 30 m or more depending on the desired bench height
Parallel query processing 1 translation of the relational algebra expression to a query tree 2 optimisation reordering of join operations in the query tree and choose among different join algorithms to minimise the cost of the execution 3 parallelisation transforming the query tree to a physical operator tree and loading the plan to the
Data is generated at an unprecedented rate surpassing our ability to analyze them The database community has pioneered many novel techniques for Approximate Query Processing AQP that could give approximate results in a fraction of time needed for computing exact results In this work we explore the usage of deep learning DL for answering aggregate
Thus in contrast to traditional machine learning algo rithms a system for implementing Approximate Query Processing using dynamic machine learning algorithms has been developed The queries may be dynamically entered based on the stakeholderâ s needs in terms of different sub sets of features The system generates the model
