preprocess the MLF file: extract video paths, phonemes and their times, and the corresponding frames in the video. extract all frames from the video, cropping the video to some box roughly corresponding to the face (to make further processing easier) write phonemeframe information to both a txt and a mat file; remove unneccessary frames
The manufacturing of cement begins with the extraction and preparation of raw material – a process covering the stages from raw material quarrying to feeding the raw meal into the preheater. The purpose of optimum raw material preparation for the cement manufacturing process is to supply the downstream burning process with a raw
processing. Shotrock moisture is required to be monitored because significant changes in moisture almost always require changes in downstream processing. CRUSHING The first step of processing begins after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates.

Portland cement raw material mainly consists of limestone and clay. This means that the raw materials used in the production of Portland cement contain calcium carbonate and compounds of silicate aluminum. Extraction of raw materials: Mines of cement raw materials, including limestone, clay, Marley, gypsum and like these, is an barefaced Mine.
The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and durability, strength, and uniform appearance of the hardened concrete while being economical.
