modeling of the connections per day with time series did not give good results (the errors in some case exceeded the 200%), one of the reason of this bad performance was represented by the sharp fluctuations of the number of connections. On the other hand the results obtained when modeling the average number of connections per week were encouraging. In particular, Figure 3 and Figure 4 report r...

Bartkowiak and Szustalewicz, 1997 (B&Sz), have proposed an implementation of the grand tour algorithm designed specially to detect outliers in multivariate data. The algorithm works by performing a sequence of rotations and projections onto a speciic 2D-plane ((proj). This is equivalent to perform a series of rotations yielding transformed coordinates of the data: X (tr) = XA, with A being the ...

The inherent randomness, intermittence and volatility of wind power generation compromise the quality system, resulting in uncertainty system's optimal scheduling. As a result, it's critical to improve assure real-time grid scheduling grid-connected farm operation. Inferred statistics are utilized this research infer general features based on selected information, confirming that there differen...

The role of microglia in neurodegenerative diseases has been controversial. In this issue, Keren-Shaul et al. identify a unique population of disease-associated microglia (DAM) that develop in two steps and may help to restrict damage in Alzheimer and related diseases.

In this paper, we give a weakly stable algorithm to solve a block Toeplitz system of linear equations. If the \look-ahead" steps taken to compute the parameters of the inversion formula for the block Toeplitz matrix are small compared to the order n of the matrix, the algorithm requires O(n 2) oating point operations. The parameters of the inversion formula are interpreted and computed in a rec...

The largest minimum weight of a self-dual doubly-even binary (n, k, d) code is d = 4bn/24c+ 4. Of such codes with length divisible by 24, the Golay Code is the only (24, 12, 8) code, the Extended Quadratic Residue Code is the only known (48, 24, 12) code, and there is no known (72, 36, 16) code. One may partition the search for a (48, 24, 12) self-dual doubly-even code into 3 cases. A previous ...

We study the problem of decentralized fault prognosis of partially-observed discrete event systems. In order to capture the prognostic performance issue in the prognosis problem,we propose twonew criteria: (1) all faults can be predicted K steps ahead; and (2) a fault will occur for sure withinM steps once a fault alarm is issued; and we refer to (M, K) as the performance bound of the prognosti...
