Indoor air quality (IAQ) in nursery schools is an emerging public health challenge. Particular attention should be paid to younger children, because they are more vulnerable to air pollution than older children. Among air pollutants, fine particulate matter (PM2.5) is of the greatest interest mainly due to its strong association with acute and chronic… (More)
A weekly seminar consisting of seven composers and one computer scientist was convened for the purpose of exploring questions surrounding how technology can support aspects of the computer music composition process. The composers were introduced to an existing interactive software system for creating new musical interfaces and compositions, which they used… (More)
The Leap Motion device opens new doors for mapping various degrees of human motion for musical control and expression. In this paper, we explore implementations of the Leap Motion in sound synthesis and interactive live performance. The Leap Motion is a USB computer peripheral released in mid-2013 that uses IR cameras to track hand and finger location with… (More)
In the paper a new combinatorical interpretation of the Jordan numbers is presented. Binomial type formulae connecting both kinds of numbers mentioned in the title are given. The decomposition of the product of polynomial of variable n into the sums of kth powers of consecutive integers from 1 to n is also studied.
– In this paper an application of the variational iteration method for determining the temperature in the heterogeneous casting-mould system is presented. Considered problem is modeled by means of the system of two heat conduction equations – for the casting and for the mould, on the contact surface of which the boundary condition of the fourth kind with… (More)
This study reports the concentrations of PM1 trace elements (As, Cd, Co, Cr, Hg, Mn, Ni, Pb, Sb and Se) content in highly mobile (F1), mobile (F2), less mobile (F3) and not mobile (F4) fractions in samples that were collected in the surroundings of power plants in southern Poland. It also reports source identification by enrichment factors (EF) and a… (More)
The Leap Motion opens new possibilities for mapping the various degrees of motion of the human hand with musical expression. The Leap Motion is a computer peripheral released in mid 2013 that uses IR cameras to track hand and finger location with unprecedented accuracy. In this paper, we explore implementations of the device in sound synthesis and effects… (More)
