In this paper a simultaneous-equations model of firm closing and wage determination is developed in order to analyse how wages adjust to unfavorable shocks that raise the risk of displacement through firm closing, and to what extent a wage change affects the exit likelihood. The results show that the fear of job loss generates bargaining concessions instead of compensating differentials. A nove...

We report that an electron beam focused for high resolution imaging rapidly initiates observable crystallization of amorphous Me-Si-C films. For 200-keV electron irradiation of Nb-Si-C and Zr-Si-C films, crystallization is observed at doses of ~2.8*10 and ~4.7*10 e /nm, respectively. The crystallization process is driven by atomic displacement events, rather than heating from the electron beam ...

An efficient measure of the concrete block structure inspection is needed with the increasing demand for concrete blocks. Cracks in the surface of RC member's can be used as a useful measure of quake-proofness of a construction or material fatigue. Specialists used to observe the cracks and experimentally inspect the structures, while applying destructive forces to the blocks. This paper propos...

This paper proposes a Delay-Based Multicast Routing Protocol (DBMRP) for multicast transmissions in ad hoc wireless networks. The DBMRP uses an on-demand, source-based multicast routing protocol, which is based on the tree forwarding methodology. The queuing delay and link delay of each visited mobile node are used to establish the multicast tree. In addition, DBMRP selects Displacement Nodes (...

Abstract The demand for seafood is increasing globally and being met, in some cases, by unsustainable fishing practices. When a country fishes outside of its jurisdiction, any negative social environmental impacts associated with are displaced to the fished location may not be compensated. This particularly problematic when jurisdictions poorer, less-effective, fisheries management than itself ...

This work deals with innovative energy efficient fluid power systems for mobile applications. The subjects taken up concern to what extent and how energy losses can be reduced in mobile working hydraulics systems. Various measures are available for increasing energy efficiency in these kinds of systems. Examples include: Flow controlled systems The pump controller is switched from a load sensin...

composites provide design flexibility because many of them can be moulded into complex shapes.  carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance with high specific strength and stiffness. these properties led to their numerous advanced applications ranging from military and civil aircraft structures to consumer products. the modelling of beams undergoing arbitrarily ...

numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. this study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. the crack tip element and a higher order boundary displacement collocation techn...
