Rolling bearings are one of the most important noise and vibration generator into mechanical constructions. Therefore, it is very important to have knowledge of the rolling element bearings influence on the level of noise and vibration in this systems. This paper deals with a basic forms for generation of vibration and noise of rolling element bearing and suggestions of vibration analysis signi...

Demand-controlled relubrication by grease analysis during operation

Bearings are mechanical dissipative systems that, when perturbed, relax toward a synchronized (bearing) state. Here we find that bearings can be perceived as physical realizations of complex networks of oscillators with asymmetrically weighted couplings. Accordingly, these networks can exhibit optimal synchronization properties through fine-tuning of the local interaction strength as a function...

STUDY DESIGN Single-group, repeated-measures design. OBJECTIVE To compare patellofemoral joint kinematics during weight-bearing and non-weight-bearing knee extension in persons with lateral subluxation of the patella. BACKGROUND The only previous study to quantify differences in patellofemoral joint kinematics during weight-bearing and non-weight-bearing tasks was limited in that static loa...

Physical activity is an essential part of general health and diabetes management. However, recommending weight-bearing physical for people with plantar diabetic foot ulcers controversial, even when gold standard offloading devices are used, as it commonly thought to delay healing. We aimed narratively review relevant studies investigating the relationship between ulcer healing activity, pressur...

New demands associated with living in a highly-technological and globallyof competencies than previous generations of students needed. The general goal of education is to prepare young people to live independent and productive lives. Unfortunately, our current educational system is not keeping pace with these changes and new demands. The world is becoming increasingly complex and to make progre...
