Concentrated, non-crystallizing colloidal suspensions in their approach of the glass state exhibit distinct dynamics patterns. These patterns suggest a powerlaw rheological constitutive model for nearglass viscoelasticity, as presented here. The rheological parameters used for this model originate in the mode-coupling theory. The proposed constitutive model provides explicit expressions for the...

To understand the dynamic rheological behavior of polar molecular electrorheological (PMER) fluids, the shear stress and viscosity of the colloids are compared with the parameters of their lamellar structures which are obtained simultaneously with the rheological characteristics using an electrorheoscope. The results of the experiments and molecular dynamics simulation indicate that the shear s...

The effect of different extraction rates (64%, 82% and 90%) of wheat flour on the rheological properties of the wheat flour dough was investigated. A complete study of the rheological behavior of the wheat flour dough was performed by using three different instruments namely alveograph, extensograph, and farinograph. The correlation coefficient among the various parameters of applied methods wa...

Abstract In video-records, objects moving in intracellular regions are often hardly detectable and identifiable. To squeeze the information on flows, we propose an automatic method of reconstruction flow velocity fields based only a recorded video unstained cell. The basis is detection speeded-up robust features (SURF) assembling them into trajectories. Two components motion—direct Brownian—are...

Automobile industry and magneto-rheological dampers are now a new area of research. Magneto-rheological mufflers utilize the energy generated by magnetic fields, scientists have initiated re-consideration damping systems. The suspension system based on fluid in modern era is becoming an intelligent with superior properties such as strength, controllability, range, response time, utilization, st...

An end milling process is widely used in fabrication of complex contours and shape parts at high spindle speeds. Many researchers try to investigate one of important aspect, which come across during machining is the self exited chatter vibration which causes severe damage of the tool and quality of the machined surface. The present work is focused on the Magneto-Rheological Damping effect on st...
