Currently, the Quartz Flexible Accelerometer (QFA) mounted for applications working in high acceleration environment are suffering from fracture of flexible beams under external shock. This paper presents mechanical model and reliability design approach QFA to maintain measuring ability a fractured state. The structural parameters changed significantly state compared those original model. A mod...

Quenching affects the mechanical and corrosion properties of precipitation-hardenable alloys such as aluminum alloy 7075-T6 (AA7075-T6). In this paper, as-quenched AA7075-T6 are predicted within framework quench factor analysis (QFA), using cooling curves obtained from a test. Theoretical computational approaches used to predict spatial temporal variations temperature. The temperature consequen...

Abstract During cerebral revascularization surgeries, blood flow values help surgeons to monitor the quality of procedure, e.g., avoid hyperperfusion syndrome due excessively enhanced perfusion. The state-of-the-art technique is ultrasonic probe that has be placed around vessel. This causes contact between and vessel, which, in worst case, leads rupture. recently developed intraoperative indocy...

The regular language (a+ b)∗a (the words in alphabet {a, b} having a as the last letter) is at the moment a classical example of a language not recognizable by a one-way quantum finite automaton (QFA). Up to now, there have been introduced many different models of QFAs, with increasing capabilities, but none of them can cope with this language. We introduce a new, quite simple modification of t...

Two quantum finite automata are equivalent if for all input string ω over the input alphabet the two automata accept ω with equal probability. In [Theoret. Comput. Sci. 410 (2009) 3006-3017], it was shown that a k1-letter QFA A1 and a k2-letter QFA A2 over Σ = {σ}, are equivalent if and only if they are (n1 + n2) 4 + k − 1-equivalent where ni is the number of states of Ai, i = 1, 2, and k = max...

PURPOSE To compare computerized analysis with traditional grading methods in the analysis of fluorescein angiograms from patients with choroidal neovascularization (CNV) due to age-related macular degeneration (AMD) and to examine the clinical relevance of parameters generated by computerized analysis by testing their relationships with clinical measures of vision. METHODS Custom quantitative...

We prove the following facts about the language recognition power of quantum Turing machines (QTMs) in the unbounded error setting: QTMs are strictly more powerful than probabilistic Turing machines for any common space bound s satisfying s(n) = o(log log n). For " one-way " Turing machines, where the input tape head is not allowed to move left, the above result holds for s(n) = o(log n). We al...

Quantum finite automata (QFA) are basic computational devices that make binary decisions using quantum operations. They known to be exponentially memory efficient compared their classical counterparts. Here, we demonstrate an experimental implementation of multi-qubit QFAs the orbital angular momentum (OAM) single photons. We implement different high-dimensional encoded on a photon, where multi...

Quantile factor models (QFM) represent a new class of for high?dimensional panel data. Unlike approximate (AFM), which only extract mean factors, QFM also allow unobserved factors to shift other relevant parts the distributions observables. We propose quantile regression approach, labeled Factor Analysis (QFA), consistently estimate all quantile?dependent and loadings. Their asymptotic are esta...

Diante da importância para estudos epidemiológicos objetivou-se elaborar um instrumento avaliar o consumo de alimentos com alto teor sódio. Recordatório 24 horas (R24) foi aplicado em 50 indivíduos ?18 anos, ambos os sexos, identificar e preparações consumidas. Para a elaboração do questionário frequência alimentar sódio (QFA-ATS) foram selecionados quantidade ?400mg por 100g/mL alimento. A lis...
