Drilling a deep vertical well at a low cost is very important for Cosmetics accelerating the exploration and development of oil and gas resources.Vertical drilling BHA design is the key to drill a vertical well, however the BHA design is still an art not science in some formation.In this paper, a new mechanical model of bent-housing motor BHA is es

The paper discusses associative meaning, i.e.one existing over and above the customary denotation, specifically the type arising from a text segment larger than a single word.The idea is of fairly recent origin, focuses on negative Bow and positive semantic effects, and stems from corpus-based findings.Dictionaries are uneven in their treatment of

The processing of raw materials in thin layers has a special significance in the technological food processes, because technology frequently involves operations of concentrating liquid products, which can lose the beneficial properties when heated to high temperatures and which can stick when processed for a long time.In this case, the efficiency o

In view of problem of bad sensitivity existed in GCTP-ZP01 detection system of discal brake which uses mechanical switch to detect wear of discal brake and drowsiness of spring, the paper proposed a reform Bow scheme of GCTP-ZP01 detection system of discal brake Vertical Flags based on embedded configuration software and S7-200 PLC.It introduced de

Some novel applications require the tracking/rejection of biased sinusoidal reference/distur-bances.According to the internal model principle (IMP), a controller must embed the model of a biased sinusoidal signal Power Control Board to track references and also reject perturbations modeled through the aforementioned signal.However, the design of th
