... to correctly track-keep the prescribed target track of set points or miner path. One of the control algorithms is the successive learning track-keeping control (SLTC) algorithm. It can learn and overcome the uncertainties, such as variation of soil friction and hydrodynamic drag during such a maneuver...

Rosemont, Illinois Introduction Asbestos is a generic name given to the fibrous variety of six naturally occurring minerals that were mined...

... for laboratory testing to assess the engineering properties of the frozen muskeg, insitu testing of the muskeg and underlying mineral soils, and numerical modeling of a frozen muskeg layer subject to loading by heavy drilling equipment. This paper reports on the numerical modeling to assess the wheel load...

... available. Furthermore, the petrophysical equations needed to convert the dielectric permittivity values measured to estimated moisture content are fairly wellestablished and universal for coarse-grained mineral soils (Topp et al., 1980). However, the measurement volume of such a sensor is on centimeter...

... ABSTRACT When weak axial soil restraint on an onshore buried pipeline occurs, thermal transients can activate pipe walking; a behavior consistent with occurrences in offshore pipeline applications. Unlike the offshore occurrences, the onshore pipe end rigidity caused by the surrounding mineral...

... the earth materials that do not contain conductive minerals, like sedimentary rocks. The previous IP studies of nonmetallic earth materials were focused on clay mineral soils, sandy and shaly sediments containing clay minerals (Klein and Sill, 1982). Laboratory studies of the electrical characteristics...

..., the biocide must survive and function under varying conditions. The most aggressive conditions involve the downhole environment where temperature and salinity extremes may occur and reactivity with the substrata (rocks, mineral, soil, hydrocarbons) create a complex set of interacting influences. This study...

... Abstract Determination of P-wave velocity (V p ), which is closely related to intact rock, is a nondestructive, easy and less complicated procedure. Due to these advantages, there is an increasing trend to predict the geomechanical properties of rocks from V p . In addition to mineral content...

.... The cuttings may thus be viewed as minerals accompanied by chemical compounds which are environmentally acceptable. The minerals are similar to mineral soils. Together with new available treatment techniques this suggest that final disposal of oily drill cuttings may be solved by utilizing the cuttings as soil...
