Most induction algorithms for building predictive models take as input training data in the form of feature vectors. Acquiring the values of features may be costly, and simply acquiring all values may be wasteful, or prohibitively expensive. Active feature-value acquisition (AFA) selects features incrementally in an attempt to improve the predictive model most cost-effectively. This paper prese...
This paper proposes a novel method to determine a priority for applying selective triple modular redundancy (selective TMR) against single event upset (SEU) to achieve cost-effective reliable implementation of application circuits onto coarse-grained reconfigurable architectures (CGRAs). The priority is determined by an estimation of the vulnerability of each node in the data flow graph (DFG) o...
ver pessoas próximas nas etapas do aborto – a decisão, as técnicas, a recuperação, etc. Aqui, re-tomo um personagem bastante importante no apoio às questões reprodutivas das mulheres melgacenses. Diante do aborto, elas contavam com a presença de " parteiras " , " aparadeiras " ou " pegadeiras de menino " , como eram chamadas. Nas primeiras vezes em que visitava e/ou con-versava com as parteiras...
در عرصه هوش مصنوعی تکنیک هایی به طور گسترده به عنوان الگوریتم های تکاملی (eas) طبقه بندی شده اند و حدود چهار دهه است، مورد تحقیق و بررسی قرارگرفته اند. از مهم ترین تکنیک های تکاملی که به صورت وسیع مورد بررسی قرارگرفته اند الگوریتم های ژنتیک (ga) هستند. الگوریتم های ژنتیک تکنیک های جست وجویی بر پایه ی نظریه ی داروین هستند که در حل مسائل بهینه سازی دشوار مفید هستند. چندبعدی بودن مسائل بهینه سازی،...
devices necessitate evaluating the SEU mechanisms of FinFET circuit stability at low supply voltages dissipation, it is also necessary over a range of voltages. FinFET proton exponential low simulations show that the weak variation of supply voltage critical charge Index Terms particles, Neutrons, Heavy The Semiconductor Industry Association (SIA) roadmap has identified power dissipation as one...
Voltamogramas cíclicos de nitazoxanida medidos no eletrodo de gota de mercúrio no tampão universal Britton-Robinson com valores de pH de 2 a 11 contendo 20% (v/v) de etanol exibiram um único pico catódico irreversível de 4-elétrons, correspondendo à redução de seu grupo NO 2 para hidroxilamina. Observou-se que a nitazoxanida adsorve na superfície do eletrodo de mercúrio numa monocamada com cobe...
We measured single event upsets (SEUs) and multiple cell upsets (MCUs) of a flip-flop array in a 65nm bulk CMOS process using accelerated white neutron beams. The flipflop array embeds 84,000 FFs constructing a 84,000bit shift register. Its cell structure is so-called tapless, in which no standard cell contains any well tap. Measurement results from 26 DUTs including 2.2Mbit FFs show that both ...
A embolia pulmonar (EP) constitui a terceira causa mais frequente de doença cardiovascular aguda, depois do acidente vascular cerebral e do enfarte agudo do miocárdio. A rapidez no diagnóstico, estratificação de risco e tratamento de doentes com EP aguda permitem reduzir a sua mortalidade. Os desenvolvimentos dos métodos de imagem das últimas décadas trouxeram significativas mudanças nos algori...
