Abstract: It is assumed that a beam made of material has a physical nonlinear behavior. This beam is analyzed under the moving concentrated and distributed continuous loads. The vibration equations of motion are derived from the Hamilton's Principle and Euler–Lagrange Equation. In this study, the amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam has b...

filter is one of the main components of embankment dams. by a simple but effective performance, filter protects the dam against erosion and soil scouring in impervious core caused by leakage (piping) and makes it safe. interaction between filter and erodible base soil is a complex phenomenon which is dependent upon several factors, and has challenged researchers for better understanding the fil...

This work presents data confirming the existence of a scan speed related phenomenon in contact-mode atomic force microscopy (AFM). Specifically, contact-resonance spectroscopy is used to interrogate this phenomenon. Above a critical scan speed, a monotonic decrease in the recorded contact-resonance frequency is observed with increasing scan speed. Proper characterization and understanding of th...

Acute subdural hematoma (ASDH) constitutes one of the most critical emergencies in neurosurgery and rapid spontaneous resolution of ASDH is an infrequent phenomenon. Several mechanisms have been attributed to explain this phenomenon including redistribution of subdural blood, dilution by cerebral spinal fluid and brain atrophy. Rapid resolution of ASDH related to coagulopathy is a rare phenomen...

The subjects of heat transfer and cooling system are very important topics in the Internal Combustion Engines (ICE). In modern cooling systems, low weight, small size and high compactness are the critical designing criteria that requires heat transfer enhancement. Boiling phenomenon which is occurred in the water jacket of the ICE is one of the methods to increase heat transfer in the coolant s...

Drawing on an analogy to critical phenomena, it was shown that the Nikuradse turbulent friction factor (ft) measurements in pipes of radius R and wall roughness r can be collapsed onto a one-dimensional curve expressed as conveyance law ftRe1/4=go(?), where Re is bulk Reynolds number ?=Re3/4(r/R). The implicit function go(.) conjectured based matching two asymptotic limits ft. However, connecti...

This paper is a Critical examination of the fundamental role thinking plays in human life. The theory presented here is derived from my previously published Critical theory of the phenomenon of mind 1 . An understanding of that theory is propaedeutic for the arguments and deductions presented in the present treatise. A glossary of technical terminology used here is available. 2 By analogy with ...
