Strategi Komunikasi Public Relations

Living man in interrelates society. Relationship among human being done by gets communication so man one by another one mutually understand and influence regard for the benefit, it that always been practiced by Public Relations( liaison) in a governance and also firm institute to reach to the effect which ices. The institute of Public Relations declares for,”Public Relations is overall effort which be passed off by design and berkesenambungan in order to creates and pet keenness and mutual understanding among an organization with whole its member “. In this case, Public Relations in give distribution on manajement's strategy there is two: First, Doing task as part of Public Relations's strategy and involvement in comprehensive process and gives benefit for management an organization. Both of, Public Relations gets role in management strategy in bring off activity to reach to the effect good one gets internal character and also external one correspond to that desirable by good institute on level governance and firm

Common and Spatial Drivers in Regional Business Cycles

We examine real business cycle convergence for 41 euro area regions and 48 US states. Results obtained by a panel model with spatial correlation indicate that the relevance of common business cycle factors is rather stable over the past two decades in the euro area and the US. Ongoing business cycle convergence often detected in a country data is not confirmed at the regional level. The degree of synchronization across the euro area is similar to that to be found for the US states. Thus, the lack of convergence does not seem to be an impediment to a common monetary policy.Business cycle convergence, spatial correlation, spatial panel model

A quantum-dot heat engine operating close to the thermodynamic efficiency limits

Cyclical heat engines are a paradigm of classical thermodynamics, but are impractical for miniaturization because they rely on moving parts. A more recent concept is particle-exchange (PE) heat engines, which uses energy filtering to control a thermally driven particle flow between two heat reservoirs. As they do not require moving parts and can be realized in solid-state materials, they are suitable for low-power applications and miniaturization. It was predicted that PE engines could reach the same thermodynamically ideal efficiency limits as those accessible to cyclical engines, but this prediction has not been verified experimentally. Here, we demonstrate a PE heat engine based on a quantum dot (QD) embedded into a semiconductor nanowire. We directly measure the engine's steady-state electric power output and combine it with the calculated electronic heat flow to determine the electronic efficiency $\eta$. We find that at the maximum power conditions, $\eta$ is in agreement with the Curzon-Ahlborn efficiency and that the overall maximum $\eta$ is in excess of 70$\%$ of the Carnot efficiency while maintaining a finite power output. Our results demonstrate that thermoelectric power conversion can, in principle, be achieved close to the thermodynamic limits, with direct relevance for future hot-carrier photovoltaics, on-chip coolers or energy harvesters for quantum technologies

Regionale Konjunkturunterschiede kein Hinderungsgrund für Geldpolitik im Euroraum

Von Kritikern der Europäischen Währungsunion wird oft behauptet, die realwirtschaftliche Entwicklung in den einzelnen Regionen sei zu unterschiedlich, als dass eine einheitliche Geldpolitik effizient sein könne. Wie berechtigt solche Befürchtungen sind, lässt sich durch einen Vergleich des Euroraums mit einer schon seit langem funktionierende Währungsunion - den USA - prüfen. Es zeigt sich, dass die Unterschiede in der konjunkturellen Entwicklung zwischen den Regionen der Eurozone nicht größer sind als zwischen den Bundesstaaten der USA. Somit sind die Erfolgsaussichten der Geldpolitik im Euroraum keineswegs schlechter als in den USA.convergence, Spatial correlation, Spatial panel model

Feasibility analysis of channel equalizers using Kharitonov-type results

Necessary and sufficient conditions for determining the robust location of the roots of a family of polynomials are presented. This family appears when multipath fading channels are considered due to the uncertainty in the channel impulse response. The uncertainty is reflected by means of confidence intervals for the channel parameters. A feasibility analysis of digital equalizers is performed in the frequency domain to determine whether the poles are to be found in a prespecified region of the complex plane. The resulting tests, which can be carried out in a graphical manner, are both analysis and design tools, which can help to decide the suitable length of a constrained equalizer. The analysis method presented resolves the location of the poles on a zero-forcing equalizer structure
