Forging of Solid Powder Discs of Large Slenderness Ratio
The paper reports an investigation into the forging of solid powder circular disc with large slenderness ratio, between two flat dies. The deformation pattern during the operation is influenced by many factors, which interact with each other in a complex manner. The decisive factors are the interfacial conditions, initial relative density of the preform and the geometry of the preform. An attem...
متن کاملSimulation of Dual Fuel Combustion of Direct Injection Engine with Variable Natural Gas Premixed Ratio
Nowadays, the major challenge of diesel engines development is simultaneous nitrogen oxides and soot emissions reduction without the thermal efficiency drop. Hence, different combustion concepts should be investigated to reach optimum emission and performance conditions in diesel engines without expensive aftertreatment systems. This paper presents the results of a study on a dual fuel (DF) eng...
متن کاملPausing under variable-ratio schedules: Interaction of reinforcer magnitude, variable-ratio size, and lowest ratio.
Pigeons pecked a key under two-component multiple variable-ratio schedules that offered 8-s or 2-s access to grain. Postreinforcement pausing and the rates of responding following the pause (run rates) in each component were measured as a function of variable-ratio size and the size of the lowest ratio in the configuration of ratios comprising each schedule. In one group of subjects, variable-r...
متن کاملParametric resonance in DNA.
We consider a simple mesoscopic model of DNA in which the binding of the RNA polymerase enzyme molecule to the promoter sequence of the DNA is included through a substrate energy term modeling the enzymatic interaction with the DNA strands. We focus on the differential system for solitary waves and derive conditions--in terms of the model parameters--for the occurrence of the parametric resonan...
متن کاملPulsed Parametric Resonance Magnetometer
A finite-field optical magnetometer is demonstrated that suppresses spin-exchange collisions by dressing the atoms in a sequence of transverse AC-coupled 2π pulses. In the limit of short pulses, the attainable transverse polarization is unity. On resonance, the dressing field cancels the DC magnetic field, further suppressing spinexchange relaxation as compared to light-narrowed magnetometers. ...
