in this research, shock wave motion, shock/boundary layer interaction, and flow separation in a transonic flow over a naca0012 airfoil were investigated experimentally. thirteen kulite sensors were utilized for measurement of pressure fluctuations over the airfoil. experiments were performed for angles of attack between -4 to 4 degrees and flow mach numbers of m= 0.39 to 0.82. the kulite sensor...

In this paper, a passive damper based on energy dissipation through shock and dry friction (shock-friction damper) is investigated regarding its design effectiveness for damping self-excited torsional vibrations similar to those occurring in deep drilling. The results are compared the of conventional dampers. different operational drilling parameters that change during process, such as weight b...

Are nominal prices sticky because menu costs prevent sellers from continuously adjusting their prices to keep up with inflation or because search frictions make sellers indifferent to any real price over some non-degenerate interval? The paper answers the question by developing and calibrating a model in which both search frictions and menu costs may generate price stickiness and sellers are su...

The present paper examines a two-country model, one with flexible wage and prices (which seems to characterize most high performance East Asian economies), and the other with sticky wage and prices. Wage and prices often “over-shoot” in the flexible wage economy. The impacts of fixed and floating exchange rage regime on the flexible wage economy is typically different. A fixed (floating) exchan...

Solution: The shock causes a leftward shift in the IS curve. Recall that the SRAS is horizontal and LRAS is vertical. Also, in the long run Y always returns to its original level, and in the short run, P does not change (sticky prices), so I won’t mention these explicitly below. The question doesn’t mention efficiency wages, so we’ll assume that the FE curve is our usual output supply curve, an...

This paper characterizes Federal Reserve policy since 1980 as one that actively manages short-term nominal interest rates in order to control inflation and evaluates this policy using a dynamic, stochastic, sticky-price model of the United States economy. The results show that the Fed’s policy insulates aggregate output from the effects of exogenous demand-side disturbances and, by calling for ...

This paper presents a potential solution to the home bias puzzle based on a new open economy macroeconomics model. In response to technology shocks, sticky prices generate a negative correlation between labor income and the profits of domestic firms, leading to home bias in equity holdings. In contrast, under flexible prices, labor income and the profits of the domestic firms are positively cor...

this paper seeks to document the specific structural patterns of bit hilanis architecture which were in used in the ancient near east from the second to the first millennium b.c. the recognition of bit hilanis architectural characteristics as well as their provenances and their spread from anatoly to palestine have always remained the important issues to be addressed by art historians and archa...

• Three selectable full scales (250/500/2000 dps) • I2C/SPI digital output interface • 16 bit-rate value data output • 8-bit temperature data output • Two digital output lines (interrupt and data ready) • Integrated lowand high-pass filters with userselectable bandwidth • Wide supply voltage: 2.4 V to 3.6 V • Low voltage-compatible IOs (1.8 V) • Embedded power-down and sleep mode • Embedded tem...

This paper evaluates the welfare effects of a monetary union (MU), compared to a  oating exchange rate regime, using a quantitative business cycle model of a two-country world with sticky prices. It is assumed that, under a  oat, there are shocks to the uncovered interest rate parity (UIP) condition. These shocks are shown to have a negative effect on welfare—the detrimental effect is stronge...
