  - Year 2017

  Musical instruments are very various in terms of sound quality with their timbre shaped by materials and geometry. Materials' impact is commonly treated as dominant one by musicians, while it is unclear whether it is true or not. The research proposed in the study focuses on determining influence of both these factors on sound quality based on their impact on harmonic composition. Numerical approach has been chosen to allowed independent...

  - REVIEW OF SCIENTIFIC INSTRUMENTS - Year 2022

  Electronic noise has its roots in the fundamental physical interactions between matter and charged particles, carrying information about the phenomena that occur at the microscopic level. Therefore, Low-Frequency Noise Measurements (LFNM) are a well-established technique for the characterization of electron devices and materials and, compared to other techniques, they offer the advantage of being non-destructive and of providing...

• Features of load and wear of main propulsion devices on sea-going ships with piston combustion engines and their impact on changes in technical states of the systems

  Publication

  • J. Girtler

  - Polish Maritime Research - Year 2017

  The paper presents the specificity of operation of propulsion systems of seagoing ships which causes the need to control the load on them, especially on their engines called main engines. The characteristics of the load on the propulsion systems, especially on the main engines as well as on the shaft lines and propellers driven by the engines, along with the process of wear in tribological joints (sliding tribological systems)...

• Experimental verification of a new method of loop resistance testing in low voltage systems with residual current devices

  Publication

  • S. Czapp
  • K. Borowski

  - Year 2016

  A periodical verification of the effectiveness of protection against electric shock shall be performed in low voltage systems. The scope of this verification includes loop impedance/resistance testing. If a residual current device is installed in a tested circuit, this testing is problematic. A residual current device trips out during the test, because of the high value of measurement current. This precludes the execution of the...

• Electrostatic interactions in finite systems treated with periodic boundary conditions: Application to linear-scaling density functional theory

  Publication

  • N. Hine
  • J. Dziedzic
  • P. Haynes
  • C. Skylaris

  - JOURNAL OF CHEMICAL PHYSICS - Year 2011

  We present a comparison of methods for treating the electrostatic interactions of finite, isolated systems within periodic boundary conditions (PBCs), within density functional theory (DFT), with particular emphasis on linear-scaling (LS) DFT. Often, PBCs are not physically realistic but are an unavoidable consequence of the choice of basis set and the efficacy of using Fourier transforms to compute the Hartree potential. In such...

• Risk criteria for sea-going ships arising from the operation of the main engines' crankshaft - conecting rod - piston systems

  Publication

  • R. Liberacki

  - Journal of Polish CIMEEAC - Year 2012

  In the article the risk criterion for sea-going ships arising from the operation of the main engines' crankshaft - connecting rod - piston systems is proposed. These criterion is based on the procedures recommended in the Formal Safety Assessment method developed under the auspices of International Maritime Organization (IMO). First of all the collective risk criterion for ship has been proposed. In the next step, the share of...
