Data warehouse acting as a decision support systems, Data warehouses standardize the data across the organization so that there will be one view of information. Data warehouses can provide the information required by the decision makers. Developing a data warehouse for educational institute is the less focused area as educational institutes are non-profit and service oriented organizations. In ...

OBJECTIVE Solastalgia is a new concept developed to give greater meaning and clarity to environmentally induced distress. As opposed to nostalgia--the melancholia or homesickness experienced by individuals when separated from a loved home--solastalgia is the distress that is produced by environmental change impacting on people while they are directly connected to their home environment. The pap...

Recently, there is an increasing interest in mining structured data. Several frequent subgraph mining systems have been proposed. However, these usually consider general graphs. One can show that frequent subgraph mining for general graphs can not be performed in output-polynomial time. In practice however, data usually does not consist of arbitrary graphs but has a much simpler structure. In t...

With the advent and wide spread use of computers a number of algorithms have been developed to determine the optimum ultimate pit limits in open pit mining. The main objective of these algorithms is to find groups of blocks that should be removed to yield the maximum overall mining profit under specified economic conditions and technological constraints. The most common methods are: Lerchs and ...

Open-Pit Production Scheduling (OPPS) problem focuses on determining a block sequencing and scheduling to maximize Net Present Value (NPV) of the venture under constraints. The scheduling model is critically sensitive to the economic value volatility of block, block weight, and operational capacity. In order to deal with the OPPS uncertainties, various approaches can be recommended. Robust opti...

Given a block-model of an open cut mine, a production scheduling policy defines which blocks should be extracted, when they should be extracted, and what should be done with them once extracted (i.e., sent to a mill, waste-dump, stockpile, etc.). The conventional three-step heuristic for constructing such a scheduling is as follows: First, compute an ultimate-pit. Second, subdivide the ultimate...

Global telecommunication systems are built with extensive redundancy and complex management systems to ensure robustness. Fault identi cation and management of this complexity is an open research issue with which data mining can greatly assist. This paper proposes a hybrid data mining architecture and a parallel genetic algorithm (PGA) applied to the mining of Bayesian Belief Networks (BBN) fro...

This work presents some initial ideas on a data mining based approach for building affective collaborative systems. In particular, we focused on the modeling issues involved in providing open affective student interaction models by using data mining techniques. The approach facilitates transferability and analysis without human intervention, and extends with emotional information previous data ...

Mine fill is the material placed underground to fill the voids created by mining excavations. It provides overall large scale ground stabilization while allowing localized pillar recovery. In addition to providing a working floor or back, mine fill has the potential to reduce subsidence and minimize dilution. Mine fill is essential to cut and fill, benching and sublevel stoping mining methods. ...

Over the last several decades mechanical mining machines have developed into highly productive, light weight, mobile machines which are able to economically mine many soft rock ore bodies. Due to the utilization of disc cutters Tunnel Boring Machines, with great mass and limited mobility, have developed the ability to cut the hardest rocks at high production rates. Technological advancements ha...
