Feb 26, 2021 Process mining techniques obtain knowledge and retrieve actionable insights from processes by the means of real-time event logs extracted from company’s information systems and allow us to perform more specific types of analysis. Each event log collection represents an activity (action on a case) which has a unique activity ID.
1. increased cost of mining and processing larger values of ore. 2. availability of fresh water needed to mine and process some minerals (especially in arid/semiarid areas) 3. environmental impact of land destruction, waste, and pollution. What are the advantages and disadvantages of using microorganisms for mining.
The application of the Theory of Regions in the context of process mining has been addressed in [1], where the authors address process mining in the context of software engineering. One of the challenges faced in this context is to nd state information in event logs. …

Aug 14, 2020 Q: Why is knowledge of the Theory of Sampling important during the exploration phase of a project? A: Achieving a correct sampling practice in a mining project is an iterated process. Analysis is required every step of the way, and the right information must be produced in each stage for the sampling to work.
Limestone, dolomite, and marble - the carbonate rocks - are the principal karst-forming rocks. Karst is a type of topography that is formed on limestone, gypsum, and other rocks by dissolution that is characterized by sinkholes, caves, and underground drainage regions. Karst areas constitute about 10 percent of the land surface of the world (fi g.
The mining phase is one of the most important phases of mining activity. The necessary technological equipment and specialized technical personnel are necessary prerequisites for safe and efficient mining. The exploitation of marble has geographical and topological …

May 08, 2018 First stage of marble processing: Mining . Nature is in charge of providing marble with its shape and colour for thousands of years. Therefore, this is always a unique, rare material. Mostly composed of calcium carbonate, marble has been and continues to be used as a construction and decorative material, due to its beauty and resistance.
Marble, like all calcareous rocks, is particularly sensitive to degradation by acid chemicals and to weathering. Acid rains are one of the main degradation agents for marble artifacts. Acid rain contains carbonic, nitric and sulfuric acid, that are produced by oxidation and dissolution in water of gaseous oxides (CO 2, NO 2 and SO 2), present in the air as chemical pollutants.
There were very good mining areas around Greece. The northern mountains of Thrace had large gold and silver deposits. Cyprus was known for its copper, gold, and iron. Laurium was known for the sliver and iron ore deposits. Ancient mining techniques go well back into our history – well back into our prehistory, in fact.
Jun 05, 2019 Water has a great influence on rock fracture process, and it is necessary to explore the activity of cracks for saturated rocks at key stress points. By uniaxial compression test and acoustic emission (AE) tests, four key points of stress-strain curve for dry and saturated marble specimens are determined. Those four key stress points include: crack closure stress (point A), crack initiation ...
Feb 27, 2021 Process Mining: a Trend in Big Data Analytics Let’s see how we ended up with the need for process mining. Process mining brings the data science in action. Big Data was introduced due to intensive increase of global data. It describes large, in most cases unstructured datasets which need analysis in order to discover new […]

Oct 22, 2014 A specific sampling process can either be representative – or not. If sampling is not representative, we have only undefined, mass-reduced lumps of material without provenance (called ‘specimens’ in the theory of sampling) that are not actually worth analyzing.
Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy.

Marble is a carbonate rock, usually a marine limestone, that has been squeezed and deformed like plastic by great heat and pressure deep beneath the Earth's surface. This process is called metamorphism. There are also rare igneous carbonate rocks that have crystallized from molten magma in the same way that lavas or granites have.
classical statistical sampling theory was not adequate for such samples. ... difference is the color of the marble. But the color of the marble is not a factor that contributes to the selection process of that marble!

Jun 20, 2005 As a result, researchers working on new process mining techniques are forced to build a mining infrastructure from scratch or test their techniques in an isolated way, disconnected from any practical applications. To overcome these kind of problems, we have developed the ProM framework, i.e., an “pluggable” environment for process mining.
General System Theory was proposed in the post-war period as a unifying framework for interdisciplinary science based on the idea that systems have a set of similar properties and characteristics regardless of discipline. General System Theory laid the foundations for talking about things in terms o …
Jun 06, 2014 Stream capturing suggests that through a process called headward erosion, the Grand Canyon was cut from the west through the plateau to “capture” the river, which ran a different direction at the time.13 This is the theory many evolutionary geologists hold today, but it has seen significant changes over the last 30 years.

Marble Polishing at Alabama Marble in Sylacauga Alabama marble is among the highest quality stone in the world. It has been an important component of the state's mining industry since the 1830s, although the uses for the stone have changed over time. Centered around Sylacauga, Talladega County, the state's marble resources were first made famous by Italian sculptor Giuseppe Moretti, and stone ...
