Dyfuzyjne spalanie turbulentne metanu w strudze: analiza numeryczna płomienia Sandia D
PublicationDyfuzyjne spalanie turbulentne jest najpowszechniej występującym w zastosowa-niach przemysłowych rodzajem tego procesu. Jednak jego dokładny opis wciąż sprawia trudności i obserwuje się rozwój konkurujących modeli implementowanych w podejściu RANS (Reynolds Averaged Navier Stokes), a współcześnie coraz częściej także w metodzie dużych wirów (LES) o czym świadczą liczne publikacje [13, 16, 18, 21]. W niniejszej pracy przedstawiono...

Error analysis of calculating average d-q current components using Regular Sampling and Park transformation in FOC drives
PublicationIn electric drives using voltage source inverters, motor currents contain ripple component resulting from pulse-width modulated (PWM) voltage. The frequency range of the ripples is much higher than the bandwidth of current control. Therefore the control is performed on the basis of a fundamental current component, i.e. average value with the averaging time being the PWM period. In majority of cases the average current is measured...

Giant Reed (Arundo donax L.) Fiber Extraction and Characterization for Its Use in Polymer Composites
PublicationThis work describes an extraction method for giant reed fibers from stems and leaves based on chemical soaking and crushing through a rolling mill. Obtained fibers, together with the shredded plant (stems + leaves), are characterized in terms of chemical composition, thermal stability, morphology, and crystallinity. Mechanical properties of fibers have also been assessed (single fiber tensile tests). The results show that the proposed...

Type III Responses to Transient Inputs in Hybrid Nonlinear Neuron Models
PublicationExperimental characterization of neuronal dynamics involves recording both of spontaneous activity patterns and of responses to transient and sustained inputs. While much theoretical attention has been devoted to the spontaneous activity of neurons, less is known about the dynamic mechanisms shaping their responses to transient inputs, although these bear significant physiological relevance. Here, we study responses to transient...

Hydrophobic derivatives of 2-amino-2-deoxy-D-glucitol-6-phosphate: a newtype of D-glucosamine-6-phosphate synthase inhibitors with antifungal action.
PublicationDokonano syntezy szeregu N-acylowych i estrowych pochodnych 2-amino-2-deok-sy-glucitolo-6-fosforanu (ADGP) i zbadano ich aktywność przeciwgrzybową oraz wobec enzymów zaangażowanych we wczesne etapy biosyntezy chityny w komórkach grzybów. Wszystkie badane pochodne okazały się słabszymi inhibitorami enzymu syntezy GlcN-6-P aniżeli ADGP, ale niektóre z nich wykazywały znacznie wyższą aktywność przeciwgrzybową niż związek macierzysty....

A Note on a Problem Posed by D. E. Knuth on a Satisfiability Recurrence
PublicationWe resolve a conjecture proposed by D.E. Knuth concerning a recurrence arising in the satisfiability problem. Knuth's recurrence resembles recurrences arising in the analysis of tries, in particular PATRICIA tries, and asymmetric leader election. We solve Knuth's recurrence exactly and asymptotically, using analytic techniques such as the Mellin transform and analytic depoissonization.

Low-Power Receivers for Wireless Capacitive Coupling Transmission in 3-D-Integrated Massively Parallel CMOS Imager
PublicationThe paper presents pixel receivers for massively parallel transmission of video signal between capacitive coupled integrated circuits (ICs). The receivers meet the key requirements for massively parallel transmission, namely low-power consumption below a single μW, small area of less than 205 μm2, high sensitivity better than 160 mV, and good immunity to crosstalk. The receivers were implemented and measured in a 3-D IC (two face-to-face...

The essence of marine and coastal space – an interdisciplinary perspective
PublicationSea space has been undergoing a profound transformation. Although it retains its inspirational function in arts, literature and philosophy, it has been gaining new anthropogenic dimensions in eco-nomics and urban planning as a source of satisfying human needs i.e. the provision of harmony, beauty, off-shore energy, and biotech substances. Therefore, in this paper marine space is analyzed from a mul-tidimensional perspective of...

Efficient and robust quadratures for isogeometric analysis: Reduced Gauss and Gauss–Greville rules
PublicationThis work proposes two efficient quadrature rules, reduced Gauss quadrature and Gauss–Greville quadrature, for isogeometric analysis. The rules are constructed to exactly integrate one-dimensional B-spline basis functions of degree p, and continuity class C^{p−k}, where k is the highest order of derivatives appearing in the Galerkin formulation of the problem under consideration. This is the same idea we utilized in Zou et al....
