The chapter on Romania examines post 2008 Romanian cinema through the dual prism of its film festival successes and the developing strand of genre-based popular films. Offering an account that goes beyond the critical successes of the New Wave films, the chapter discusses the difficulty of national productions to reach local audiences despite the increased adoption of genre. It also provides some explanations for the limited output of Romanian cinema, which is notable despite the increase in European and Balkan co-productions.

This paper introduces a novel swarm intelligence based algorithm named comprehensive learning particle swarm optimization (CLPSO) to identify parameters of structural systems, which could be formulated as a multi-modal numerical optimization problem with high dimension. With the new strategy in this variant of particle swarm optimization (PSO), historical best information for all other particles is used to update a particle's velocity. This means that the particles have more exemplars to learn from, as well as have a larger potential space to fly, avoiding premature convergence. Simulation results for identifying the parameters of a five degree-of-freedom (DOF) structural system under conditions including limited output data, noise polluted signals, and no prior knowledge of mass, damping, or stiffness are presented to demonstrate improved estimation of these parameters by the CLPSO when compared with those obtained from standard PSO. In addition, the efficiency and applicability of the proposed method are experimentally examined by a twelve-story shear building shaking table model.

Substructure Approach

This paper presents an effort to apply the EKE (extended Kalman estimator) and LSE-UI (least squares estimation for unknown input) technique to detect structures damage with limited output measurements. This technique can be extended to detect structural local damage in complex structures based on substructure approach. Structural parameters and the unknown inputs are identified by a recursive algorithm based on sequential application of the extended Kalman estimator for the extended state vector and the least squares estimation for the unknown inputs. Only a limited number of measured acceleration responses of the benchmark structure subject to unmeasured excitation inputs are utilized. This structural damage detection method is applied to the ASCE SHM benchmark building to test its efficacy and provide a solution to the complex case of the Phase I benchmark problem. Damage detection results indicate that the proposed technique can detect and localize structural damage of the complex benchmark problem with good accuracy.

In Part I of the present series of researches an account was given of an investigation of the slow, non-self-propellant combustion of electrolytic gas in direct-current discharges. Owing to the limited output of the generator then available, it was not possible, except in a few isolated cases, to extend the investigation to the study of the ignition of electrolytic gas. Some time after the completion of the above-mentioned work, however, a larger high- tension direct-current generator, together with suitable smoothing chokes and condensers, became available, thus enabling us to carry out a systematic investigation of the conditions of ignition of electrolytic gas. Experimental . In the experiments to be described below, precautions were taken to eliminate as far as possible any conditions favourable to ignition, particularly heat and catalytic combustion at the electrodes, other than those due to ionisation of the gas; and then to study the effect of variations of the gas pressure upon the least-igniting current. We have been able to establish a gas pressure-least-igniting current relationship of such a nature that the conclusion may be drawn that ignition of electrolytic gas is determined, under the conditions of our experiments, by the attainment of a definite concentration of ions due to the passage of the electric current; and, further, it has been found that flame is propagated more rapidly in the gas when ionised by the electric discharge than otherwise.
