The Phoenix Deep Survey (PDS) is a multiwavelength survey based on deep 1.4 GHz radio observations used to identify a large sample of star forming galaxies to z = 1. Here we present an exploration of the evolutionary constraints on the star-forming population imposed by the 1.4 GHz source counts, followed by an analysis of the average properties of extremely red galaxies in the PDS, by using th...

imperialist competitive algorithm (ica) is a new socio-politically motivated global search strategy. the ica is applied to hybrid composite laminates to obtain minimum weight and cost. the approach which is chosen for conducting the multi-objective optimization was the weighted sum method (wsm). the hybrid composite laminates are made of glass/epoxy and carbon/epoxy to combine the lightness and...

Low-temperature and ambient-temperature nonaqueous stacking techniques in capillary electrophoresis (CE) are described for the first time. A low-temperature bath was used to control the temperature from ambient to subzero degrees, by which a novel hyphenated method, low-temperature bath-nonaqueous capillary electrophoresis stacking (LTB-NACE stacking) is demonstrated. 3,4-Methylenedioxymethamph...

We propose the use of stacking, an ensemble learning technique, to the statistical machine translation (SMT) models. A diverse ensemble of weak learners is created using the same SMT engine (a hierarchical phrase-based system) by manipulating the training data and a strong model is created by combining the weak models on-the-fly. Experimental results on two language pairs and three different si...

In this paper, we propose a gate-level NBTI delay degradation model, where the stress voltage variability due to PMOS transistors’ stacking effect is considered for the first time. Experimental results show that our gate-level NBTI delay degradation model results in a tighten upper bound for circuit performance analysis. The traditional circuit degradation analysis leads to on average 59.3% ove...

We report a new nonwrapping approach to noncovalent engineering of carbon nanotube surfaces by short, rigid functional conjugated polymers, poly(aryleneethynylene)s. Our technique not only enables the dissolution of various types of carbon nanotubes in organic solvents, which represents the first example of solubilization of carbon nanotubes via pi-stacking without polymer wrapping, but could a...

We consider the optimal design of composite laminates by allowing a variable stacking sequence and in-plane shape of each ply. In order to optimize both variables we rely on a decomposition technique which aggregates the constraints into one unique constraint margin function. Thanks to this approach, an exactly equivalent bi-level optimization problem is established. This problem is made up of ...

Tiny hollow glass microsphere (HGM) can be applied for designing new light-weighted and thermal-insulated composites as high strength core, owing to its hollow structure. However, little work has been found for studying its own overall thermal conductivity independent of any matrix, which generally cannot be measured or evaluated directly. In this study, the overall thermal conductivity of HGM ...
