• COMPARISON OF SOFTWARE AND HARDWARE REALIZATION OF AES CRYPTOGRAPHIC ALGORITHM

  Publikacja

  • M. Wójcikowski
  • B. Pankiewicz

  - Zeszyty Naukowe Wydziału ETI Politechniki Gdańskiej. Technologie Informacyjne - Rok 2007

  In this paper hardware and software realization of direct and inverse AES cryptographic algorithm is presented. Both implementations were made using the Virtex-II FPGA and were practically tested. As the criteria of comparison, the resource utilization, achieved performance and power dissipation were chosen. Hardware realization increases throughput of conversion about 190 times over software implementation and decreases the energy...

  - Elektronika : konstrukcje, technologie, zastosowania - Rok 2014

  In this paper performance of an electrocatalytic sensor in presence of chlorine is investigated. Presented studies concern sensor prepared in ceramic technology based on NASICON as a solid electrolyte with two round shaped platinum electrodes. Measurements in different temperatures have been performed in order to determine optimal sensor working temperature.

• Has EGNOS its own place in maritime navigation?

  Publikacja

  • A. Felski
  • A. Nowak

  - Rok 2015

  GNSS (in fact it usually means GPS) is at the moment the fundamental means of positioning for any variants of navigation. However some attributes of it can be not sufficient for every users or in some tasks, so there are any cases when this system needs support. From the mariner point of view pure GPS properties perfectly fulfils expectations of sailors at the open sea, however there are lot of cases, when accuracy of the system...

• Gas sensors based on conducting polymers-recent developments

  Publikacja

  • K. Dunst
  • P. Jasiński

  - Zeszyty Naukowe Wydziału ETI Politechniki Gdańskiej. Technologie Informacyjne - Rok 2018

  This work discusses sensing performance dependence of PEDOT polymer and its composites on the counter ions used in the polymerization process. The sensors based on PEDOT-RGO composite show reversible response to NO2, while on PEDOT/LiClO4 irreversible. As a result, PEDOT-RGO could be used as a typical gas sensor, while sensor based PEDOT/LiClO4 could be used as an integrating gas sensor, also known as an accumulating gas sensor....

• Design Analysis of Micro Gas Turbines in Closed Cycles

  Publikacja

  • K. Kosowski
  • M. Piwowarski

  - ENERGIES - Rok 2020

  The problems faced by designers of micro-turbines are connected with a very small volume flow rate of working media which leads to small blades’ height and high rotor speed. In the case of gas turbines this limitation can be overcome by the application of a closed cycle with very low pressure at the compressor inlet (lower than atmospheric pressure). In this way we may apply a micro gas turbine unit of accepted efficiency to work...

• Resistive gas sensors – Perspectives on selectivity and sensitivity improvement

  Publikacja

  • J. Smulko
  • M. Trawka
  • U. Cindemir
  • C. G. Granqvist
  • C. Duran

  - Rok 2016

  Resistive gas sensors are very popular and relatively inexpensive; they can operate at elevated or room temperature for years on end. The main disadvantage of resistive gas sensors is their limited selectivity and sensitivity, but various methods have been applied to improve their behavior. The composition of the porous gas sensing layer, or changes in the sensor’s operating temperature, can enhance the gas detection ability. Furthermore, emerging...

  • M. Trawka
  • P. Sedlak

  - SENSORS AND ACTUATORS B-CHEMICAL - Rok 2015

  Resistance fluctuations across polarised resistive gas sensors were studied in detail to evaluate sensor working conditions for detecting methane and ammonia at various concentrations. The 1/f noise component typically dominates other noise sources up to a few kHz and can be utilised to improve gas selectivity when compared with measurements of the sensor DC resistance. The Arrhenius plot was created and the activation energy for...

  • J. Tejchman

  - Computers and Concrete - Rok 2017

  W artykule przedstawiono wyniki doświadczalne i numeryczne dla kompozytowych płyt złożonych z żelbetu i styropianu. Wykonano doświadczenia dla płyt w skali 1:1 podczas zginania. Wyniki doświadczalne zostały modelowane stosując 2 różne modele: sprężysto-plastyczny i połączony sprężysto-plastyczny z degradacja sztywności. Oba model zostały wyposażone w długość charakterystyczna mikrostruktury. Osiągnięto dobra zgodność miedzy...
