The 2008-2009 US crisis is characterized by un unprecedent degree of international synchronization with all other G7 countries experiencing large contractions at almost the same time as the US. Another feature of the crisis is the sharp fall in US employment but not in US productivity. These two features—international synchronization and absence of significant productivity fall—are not present ...

In this paper, by defining soft ditopological spaces, a new approach to the soft topology via softset theory is made, with defining two structures on a soft set a soft topology and a softsubspace topology. Moreover, separation axioms in soft ditopological spaces are characterizedand the relations between soft topological and soft ditopological structures are investigated.Referen...

World agriculture will undergo far-reaching economic and physical change in the coming 50 years. Population increase, urbanization and income growth will drive the demand for food while high energy prices, stress on natural resources, and climate change may act to constrain supply. To feed the world’s growing population – projected to exceed 9 billion in 2050 (UN, 2009) – it will be necessary t...

The algebraic connectivity ofG is the second smallest eigenvalue of its Laplacianmatrix. Let Un be the set of all unicyclic graphs of order n. In this paper, wewill provide the ordering of unicyclic graphs inUn up to the last seven graphs according to their algebraic connectivities when n ≥ 13. This extends the results of Liu and Liu [Y. Liu, Y. Liu, The ordering of unicyclic graphswith the sma...

Puede afirmarse que entre los objetivos fundacionales del Sistema Nacional de Salud (SNS) español—aseveración que asume el discurso público dominante—destacan la universalidad, la provisión gratuita en el momento de uso y la asistencia de calidad, eficiente y equitativa. Aunque la prelación de estos rasgos pueda variar en función de quien los enuncie, en general el lugar común de todo el debate...

la mouillabilite est un phenomene pui depend d'un grand nombre de facteurs. chacun de ces facteurs , qu'il soit d'order physipue ou chimipue, joue un grand role. on peut distinguer : 1 - la granulometrie du solide. elle est en relation avec la surface sped fipue des solides . plus cette surface est en grande, plus le mouillage est fort. 2 - la temperature : l'elevation de la...

A new causal dynamic end-effector inversion method for a single flexible link manipulator is introduced. Contrary to the available non-causal inversion technique, this method does not lead to pre-actuation and works even in the presence of the purely imaginary zeros for the transfer function. Based on this approach, the desired end-effector trajectory is divided into a finite number of segments...
