Real-time heuristic search algorithms are useful when the amount of time or memory resources are limited or a rapid response time is required. An example of such a problem is pathfinding in video games where numerous units may be simultaneously required to react promptly to player’s commands. Classic real-time heuristic search algorithms cannot be deployed due to their obvious state-revisitatio...

Bit faults induced by single-event upsets in instruction may not cause a system to experience an error. The instruction vulnerability factor (IVF) is first defined to quantify the effect of non-effective upsets on program reliability in this paper; and the mean time to failure (MTTF) model of program memory is then derived based on IVF. Further analysis of MTTF model concludes that the MTTF of ...

Aqueous biphasic systems were investigated for the production of formate-amine adducts by metal-catalyzed CO2 hydrogenation, including typical scrubbing solutions as feedstocks. Different hydrophobic organic solvents and ionic liquids could be employed as the stationary phase for cis-[Ru(dppm)2 Cl2 ] (dppm=bis-diphenylphosphinomethane) as prototypical catalyst without any modification or taggin...

We introduce a nanowire-based, sublithographic memory architecture tolerant to transient faults. Both the storage elements and the supporting ECC encoder and corrector are implemented in dense, but potentially unreliable, nanowirebased technology. This compactness is made possible by a recently introduced Fault-Secure detector design [18]. Using Euclidean Geometry error-correcting codes (ECC), ...

The objectives of the present study were to evaluate the spread of Salmonella Enteritidis to different cutting boards (wood, triclosan-treated plastic, glass, and stainless steel) from contaminated poultry skin (5 log CFU/g) and then to tomatoes and to analyze the effect of different protocols used to clean these surfaces to control contamination. The following procedures were simulated: (1) no...

Anaerobic co-digestion (AcoD) can utilise spare digestion capacity at existing wastewater treatment plants (WWTP) to generate surplus biogas beyond the plant's internal energy requirement. Data from industry reports and peer-reviewed literature show that through AcoD, numerous examples of WWTPs have become net producers, necessitating other high-value applications for biogas. A globally emergin...

Based on mass and energy balance calculations, this work investigates the possibility of recovering heat nutrients (nitrogen phosphorus) from municipal sewage sludge using pyrolysis or combustion in combination with a gas scrubbing technology. Considering wastewater treatment plant (WWTP) 65,000 t/a mechanically dewatered digestate (29% total solids), 550 nitrogen 500 phosphorus were recovered ...

This paper explores advances in reconfiguration properties of SRAM-based FPGAs, namely Partial Dynamic Reconfiguration, to improve the resilience of critical systems that take advantage of this technology. Commercial of-the-shelf stateof-the-art FPGA devices use SRAM cells for the configuration memory, which allow an increase in both performance and capacity. The fast access times and unlimited...

In resting state functional magnetic resonance imaging (fMRI) studies of autism spectrum disorders (ASDs) decreased frontal-posterior functional connectivity is a persistent finding. However, the picture of the default mode network (DMN) hypoconnectivity remains incomplete. In addition, the functional connectivity analyses have been shown to be susceptible even to subtle motion. DMN hypoconnect...

Game pathfinding is a challenging problem due to a limited amount of per-frame CPU time commonly shared among many simultaneously pathfinding agents. The challenge is rising with each new generation of games due to progressively larger and more complex environments and larger numbers of agents pathfinding in them. Algorithms based on A* tend to scale poorly as they must compute a complete, poss...
