PURPOSE This study was performed to investigate the accuracies of the synthesized monochromatic images and effective atomic number maps obtained with the new GE Discovery CT750 HD CT scanner. METHODS A Gammex-RMI model 467 tissue characterization phantom and the CT number linearity section of a Phantom Laboratory Catphan 600 phantom were scanned using the dual energy (DE) feature on the GE CT...

The metabolic cost and the mechanical work of running at different speeds and gradients were measured on five human subjects. The mechanical work was partitioned into the internal work (Wint) due to the speed changes of body segments with respect to the body centre of mass and the external work (Wext) due to the position and speed changes of the body centre of mass in the environment. Wext was ...

This paper proposes integrated navigation and ̄tness biases as e±ciency regulators for inductive Genetic Programming. Evolutionary search is easy on smooth landscapes created with size-biased stochastic complexity ̄tness functions. In order to achieve continuous guidance to unvisited landscape areas, these functions require mutation and crossover applications, biased by the size of the genetic p...

Many researchers propose dedicated hardware [1, 2] to process sensor data on mobile systems, reducing the burden on generalpurpose computing units and increasing a system’s energy eciency. However, these hardware units are placed at a distance from sensors, thermally isolated to avoid an increase in thermal noise of sensors that can degrade the €delity of the sensor output signal. In this post...

We introduce the concept of product complexity in an endogenous growth model with renewable energy and expanding product variety à la Grossman-Helpman (1991). We describe the complexity of a product as an increasing function of the variety of inputs it consists of. Considering that energy is necessary to all human activities (including research), we highlight what type of long run growth path i...

Thin layer drying of Russian olive (Elaeagnusan gastifolial L.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. The selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°C. Increased air temperature...

The temperatures of red supergiants (RSGs) are expected to depend on metallicity (Z) in such a way that lower-Z RSGs warmer. In this work, we investigate the Z-dependence Hayashi limit by analysing low-Z galaxy Wolf-Lundmark-Mellote (WLM), and compare with higher-Z environments Small Magellanic Cloud (SMC) Large (LMC). We determine effective temperature ($T_{\textrm{eff}}$) each star fitting th...

The pressure drop and heat transfer characteristics of a single-phase micro-channel heat sink were investigated both experimentally and numerically. The heat sink was fabricated from oxygen-free copper and fitted with a polycarbonate plastic cover plate. The heat sink consisted of an array of rectangular micro-channels 231 lm wide and 713 lm deep. Deionized water was employed as the cooling liq...
