In the present paper, nanometer scale hydroxyapatite powders with a rod-like shape, were prepared using combined ultrasonic and microwave heating-based method. Subsequent annealing of as-synthesized at 800 ℃ for 2 h produced nanoparticles rectangular granular morphology. The particles characterized X-ray diffraction Fourier transform infrared spectroscopy methods. Also, nanoparticle ...

Heat transfer technologies are experiencing rapid expansion as a result of the demand for efficient heating and cooling systems in automotive, chemical, aerospace industries. Therefore, current study peruses an inspection mixed convective radiative Williamson flow close to stagnation point aggravated by single nanoparticle (alumina) from vertical flat plate with impact Hall. The water conveying...

In Williamson (2007), Timothy Williamson argues against “the tactic of criticizing confidence in a theory by identifying a logical consequence of the theory (not itself a logical truth) whose probability is not raised by the evidence” (232-233). He dubs it the consequence fallacy. In this paper, we will show that Williamson‟s formulation of the tactic in question is ambiguous. On one reading of...

Clustering is an important data exploration task. A prominent clustering algorithm is agglomerative hierarchical clustering. Roughly, in each iteration, it merges the closest pair of clusters. It was rst proposed way back in 1951, and since then there have been numerous mod-iications. Some of its good features are: a natural, simple, and non-parametric grouping of similar objects which is capab...

In this work we apply the recently proposed Unified Particle Swarm Optimization (UPSO) method to the search for Hadamard matrices of the Williamson type. The objective functions that arise from the classical Williamson construction, are ideally suited for UPSO algorithms. This is the first time that swarm intelligence methods are applied to this problem. Mathematics Subject Classification (2000...

The overwhelming impact of complex-phase microstructures to mechanical response in multiphase steels requires accurate constitutive properties the individual phases. However, precise prediction phase their is critical and sophisticated, commonly multiscale characterizations numerous approximations. In this work, by employing full information semi-empirical analytical models, we accurately predi...
