In this study, we present a theoretical framework combining experimental characterizations and analytical calculus to capture the firing rate input-output properties of single neurons in the fluctuation-driven regime. Our framework consists of a two-step procedure to treat independently how the dendritic input translates into somatic fluctuation variables, and how the latter determine action po...

We model the double phase-conjugate mirror (DPCM) as a function of time, the average direction of propagation of the two beams forming the DPCM, and one transverse coordinate. Calculations show that the conjugation fidelity and reflectivity have different dependencies on the photorefractive coupling coefficient times length; the fidelity turns on abruptly with a threshold, whereas the reflectiv...

A perfect algebraic immune function is a Boolean function with perfect immunity against algebraic and fast algebraic attacks. The main results are that for a perfect algebraic immune balanced function the number of input variables is one more than a power of two; for a perfect algebraic immune unbalanced function the number of input variables is a power of two. Also the Carlet-Feng functions on...

Matrix converter (MC) is an AC-AC power converter topology that directly converts energy from AC source to an AC load without using any energy storage components. Therefore, the disturbances in the input voltages can propagate onto the output side and degrade or even deteriorate the performance of motor load. This paper investigates the behavior of MC and its influence to the performance of ind...

A widely used method for determining the similarity of two labeled trees is to compute a maximum agreement subtree of the two trees. Previous work on this similarity measure is only concerned with the comparison of labeled trees of two special kinds, namely, uniformly labeled trees (i.e., trees with all their nodes labeled by the same symbol) and evolutionary trees (i.e., leaf-labeled trees wit...

The static VAR generator (SVG) is an important device in flexible AC transmission systems (FACTS) for the development of smart grids. Based on the basis principle of SVG and instantaneous reactive power theory, the conventional ip–iq and dq methods have a certain error when the three phase voltages are unbalanced. In this paper, the current detection algorithm is improved in cases of three-phas...

The complexity class PPAD (“Polynomial Parity Argument on Directed Graphs”) was proposed by Christos Papadimitriou in 1994 [6]. Its goal is to capture the complexity of searching for an object whose existence is guaranteed by the principle that, “A directed graph with an unbalanced node (indegree 6= outdegree) must have another unbalanced node.” Suppose that we describe an exponentially large g...

When an employee is hired by a company, given his/her job role, model can be built to predict an employee’s access needs. This auto-access model tries to minimize the human labor and time for granting or revoking employee access. The input to our algorithm is information about the employee’s role at the time of approval. We then use Logistic Regression, Naive Bayes and Support Vector Machine (S...
