Hydraulic bending roll system has become one of key equipments to control the exit strip shape in strip rolling mills. The hydraulic bending roll system of a hot rolling mill was researched and analyzed, and its mathematics models were founded in whole based on the action principle of some representative hydraulic components. At last, the hydraulic bending roll system was simulated with MATLAB ...

In this paper, we present a new diagnosis and prognosis method using the degree of randomness (DoR) measure and Laplace test procedure. The abnormal events are detected based on changes of randomness of vibration signals. The trend of randomness is resulted from faulty components such as roller bearings. We aim at the early detection of semi-failure events through the use of Laplace test statis...

In view of the problem plant entanglement threshing roller in process mechanized flax harvesting, a comb-brush air-suction composite capsule harvesting test stand was designed based on method capsules independently and then breaking to thresh them. The following four parameters were selected as experimental factors: shape comb tooth cross-section, rotational speed roller, relative machine trave...

Dancing on roller skates at discothecques has become very popular among the youth in the last number of years. During 1980 a number of these roller discotheques were opened in Belfast and it soon became apparent that significant numbers of young people were attending the Accident and Emergency Departments of hospitals in the city with injuries received while participating in this leisure activity.

We prove that any hyperplane H in a CAT(0) cubical complex X has no self-intersections and separates X into two convex complementary components. These facts were originally proved by Sageev. Our argument shows that his theorem (or this direction of his theorem) is a corollary of Gromov’s link condition. We also give new arguments establishing some combinatorial properties of hyperplanes. We sho...

The article presents and analyzes the results obtained from an experimental study of content toxic components in exhaust gases during operation a car engine with gasoline liquefied petroleum gas (LPG). was conducted laboratory conditions by loading driving wheels roller-type chassis dynamometer, corresponding to established movement constant speed on horizontal road section.

AIM This study aims to determine the effect of the stationary rawx, roller, and the suspension cell culture systems on the total virus yield infectivity and antigenicity. MATERIALS AND METHODS Three serotypes of foot and mouth disease virus (FMDV) (serotype A, O and SAT-2) were inoculated separately into baby hamster kidney-21 cell line in rawx, roller, and suspension cultivation systems usin...
