Program visualizations (PVs) are sometimes less effective in teaching computer algorithms than desired. One reason may be that PV designers have largely ignored the users' perceptual capabilities. We examined perceptual characteristics of bar displays, similar to those used in teaching sorting algorithms...
Usingthese techniques, we have proposed exhaustive algorithms for detection of actions in a motion piece andsubsequently classifying the segmented actions and respective characteristics of the actors. We have testedthe methods for various sequences and compared the results for a comprehensive evaluation ...
Gravitational wave telescope place extremely high demands on structural thermal deformation, making material selection a critical issue. Carbon fiber reinforced polymer (CFRP) is an ideal choice for the support structure of telescope due to its low coeff
This chapter addresses the pre-existing mathematics teacher characteristics (PMTC) of prospective mathematics teachers on entry to their teacher education program. Pre-existing teacher characteristics include abilities, knowledge, and attitudes that a ca
Gradient-based algorithms take advantage of both the objective function and its derivative with respect to the design variables to converge to the optimum more efficiently. Gradients are used to ensure that the optimizer converges to the mathematical optimality condition. Though they usu- ally need ...
The constants vary with different roughness prediction algorithms in empirical formulas. The existing empirical formula cannot be satisfied for the fractal roughness algorithm, so a new model of the ventilation resistance coefficient needs to be developed. Because f, \(\varepsilon /d\) and Re are ...
or simply unavailability of a good starting point. In modern times, global optimization primarily revolves around nature-inspired metaheuristic algorithms37,38,39. These algorithms operate on sets (populations)40of potential solutions (individuals, agents)41rather than single parameter vectors. Their globa...
A system and method for determining the characteristics of a device coupled to a client device are disclosed. A method, according to one embodiment, includes driving a display devic
Word sense disambiguation refers to the process of sorting words that have multiple meanings. Phrase identification refers to the process of relating each word to others within a phrase to derive the context of individual words. Named entity recognition generally refers to recognition of proper nouns...
Bechhoefer et al. [17] processed the vibration signatures of a split torque gearbox through a number of gear analysis algorithms to quantify the gear fault performance. Gui et al. [18 展开 关键词: GEARING machinery DYNAMIC models DYNAMICAL systems DYNAMIC loads ...
