We provide explicit bounds on the eigenvalues of transfer operators defined in terms of holomorphic data. Linear operators of the form Lf = ∑ i∈I wi · f ◦ Ti, so-called transfer operators (see e.g. [Bal, Rue1, Rue2]), arise in a number of problems in dynamical systems. If the Ti are inverse branches of an expanding map T , and the weight functions wi are positive, the spectrum of L has well-kno...

One of the key elements in production planning hierarchy is master production scheduling. The aim of this study is to evaluate and compare thirteen alternative MPS development methods, including multi-objective optimization as well as twelve heuristics, in different operating conditions for multi-product single-level capacity-constrained production systems. We extract six critical criteria from...

PURPOSE To determine the optimal combination of parameters derived from 3T multiparametric (conventional magnetic resonance imaging [MRI], diffusion-weighted [DW] and dynamic contrast-enhanced [DCE]) MRI for differentiating malignant from benign orbital lymphoproliferative disorders (OLPDs). MATERIALS AND METHODS Forty patients with OLPDs (18 benign and 22 malignant) underwent conventional 3....

Chronic (2 h/d x 8 weeks) exposure to magnetic field (MF; 50 Hz, 17.9 microT) in complete spinal cord (T13) transected rats restored food intake (FI), water intake (WI) and body weight (BW) which were decreased in the spinal cord injured rats. The results suggest a significant beneficial effect of chronic exposure to magnetic field of paraplegic rats.

This paper investigates the impact of wireless communication in manufacturing systems. By using a digital twin representation real production line, throughput evaluation is performed for various configurations considering different control schemes over Wi-Fi, 4G LTE and 5G NR. The results show that operating execution system (MES) instead Ethernet will minimally production, as not be degraded l...

We introduce a finite class of weighted quadrature rules with the weight function |x|−2a exp −1/x2 on −∞,∞ as ∫−∞|x|−2a exp −1/x2 f x dx ∑n i 1 wif xi Rn f , where xi are the zeros of polynomials orthogonal with respect to the introduced weight function, wi are the corresponding coefficients, andRn f is the error value. We show that the above formula is valid only for the finite values of n. In...

Super Wi-Fi is a Wi-Fi-like network built upon TV white spaces (TVWS) exploiting cognitive radio (CR) techniques. Super Wi-Fi is expected to achieve larger coverage than today’s Wi-Fi thanks to its superior propagation characteristics, while suffering from smaller bandwidth compared to Wi-Fi (6–8 MHz versus 20 MHz) which limits its network capacity. Therefore, it has been a common belief that S...
