The existence of a continuum of many chaotic solutions is shown for certain differential inclusions which are small periodic multivalued perturbations of ordinary differential equations possessing homoclinic solutions to hyperbolic fixed points. Applications are given to dry friction problems. Singularly pertur...
Reducing noise and flooding with innovative stone wool solutions Sustainability and energy efficiency All ROCKWOOL products are made from one of the most abundant natural materials around – volcanic rock. They can be infinitely recycled5. Through improving the thermal performance of a building, dry li...
Figure 1.Changing the friction conditions between the pad and the test sample in the presence of the liquid lubricant. The problems are complicated when dealing with a textured surface, which presents microreliefs generated specifically by applying certain processing techniques for generating the respecti...
22. A pad as defined in claim 18, in which the yarn of the pad has a high coefficient of static friction with respect to the pile material of the carpet. 23. A pad as defined in claim 18, in which said yarn is nylon where the carpet contains a substantial proportion of wool yarn....
A design emphasise is set onto the parameter speed through the water (STW); hence machinery performance and fuel consumption are directly interrelated with an object’s relative motion through a surrounding medium. Among other aspects, said relative motion/friction influences the degree of the hull-...
It is based primarily on problems with each layer of the tear film and the surface epithelium; however, the tear film changes observed in DED do not occur exclusively in a particular layer but rather in different combinations and degrees of severity. This group recommends using fluorescein dye,...
The value of the friction penalty term pfr = 40 GPa/m, which was used for the friction analysis in examples 4.1, 4.3 and 4.4 with different materials, geometrical characteristics and pre-compression stress level, has provided numerical solutions with an acceptable level of accuracy in comp...
The surface roughness of the carrier par- ticles also has a considerable in¯ uence on the adhesion and friction forces between drug and carrier particles in interactive powder mixtures s Podczeck 1997b, 1998b.. The surface roughness of the carrier parti- cles could be changed during, for...
The allowable foil length (in the machine direction) increases with: Increased sheet tension, Increased wrap angles, Increased machine speed, Smaller radius on leading edge, and, Lower web permeability. Because of friction, a passive foil will induce a drag force on the web which results in ...
