In the production function approach, an accurate output gap assessment requires a careful evaluation of the total factor productivity (TFP) cycle. We build a common cycle model that links TFP to capacity utilization and we show that, in almost all of the preenlargement EU countries, using information about capacity utilization reduces both the total estimation error and the revisions in real-ti...

We consider efficient communications over the multiple-input multiple-output (MIMO) multiway distributed relay channel (MDRC) with full data exchange, where each user, equipped with multiple antennas, broadcasts messages to all the other users via the help of a number of distributive relays. We propose a physical-layer network coding (PNC) based scheme involving linear precoding for channel ali...

In sticky price models with endogenous investment, virtually all monetary policy rules that set a nominal interest rate in response solely to future inflation induce real indeterminacy of equilibrium. Applying the Samuelson-Farebrother conditions, we obtain a necessary and sufficient condition for local real determinacy, which reveals that increasing price stickiness or letting policy respond a...

background: despite some successful dynamic simulation of self-impact double pendulum (sidp)-as humanoid robots legs or arms- studies, there is limited information available about the control of one leg locomotion. objective   : the main goal of this research is to improve the reliability of the mammalians leg locomotion and building more elaborated models close to the natural movements, by mod...

Bank of Japan May 2011 The earthquake that struck Japan in March 2011 has reduced the supply capacity of the economy, which works in the direction of tightening the output gap. At the same time, however, if weak household and corporate sentiment lead to a decline in aggregate demand, this will work in the direction of increasing the slack in the economy. Moreover, developments in supply and dem...

Among multilevel inverter topologies, asymmetric Cascaded H-Bridge (CHB) inverters have higher output-voltage levels than symmetrical ones. However, asymmetric multilevel inverters need pre-stage isolated and floating DC power sources, which make the system complicated and bulky. This paper is focused on solving the problem by using a single-core (magnetically-coupled) multiple-output forward-f...
