A digital image is a numerical representation of (usually binary) a two-dimensional image. It could be of the vector or the raster type. Normally, the phrase “digital image” refers to raster or bitmapped images. Raster images possess a fixed amount of digital values, which are called picture elements or pixels. Every image has a fixed number of rows and columns of these pixels. The pixels are stored in the memory of computers as raster images consisting of arrays of numbers. These are stored and transmitted in compressed formats (Sprawls, 2017). Computers are able to produce descriptive information about a ...

Risks to the Mine

The major hazards to the mines include the possibility of floods taking place in the sites, and they will lead to a stop of the mining process. Secondly, the mines are prone to gas explosions. The explosions will increase the hole, and might even lead to the prevention of further mining (Khan, et al. 2004). Thirdly, the mines might face chemical leakage, an act that may cause decomposition of rocks and depletion of the important resources in mines. Moreover, mines are prone to dust, that will lead to blocking of the extraction process, by occupying the region, or causing ...

Topics in Philosophy are boundless. It could deal with politics, existence of beings, the human soul, metaphysics, and much more. However, there is one unique philosophical thought which relates to nature; and this is all about vegetarianism. The known proponent of this naturalist’s view was James Rachels. The tenets of his argument started out on this major premise, that it is not correct to induce pain unless there is a justifiable reason for doing so (Rachels, 2004, p. 70). With such statement, there are induced sufferings which can be considered morally correct because they are justified by the ...
