  - GOVERNMENT INFORMATION QUARTERLY - Rok 2016

  In view of the rising social and economic inequalities, public service delivery should be both universal, i.e. independent of the recipients' social or economic status, and contextualized, i.e. able to compensate for different local needs and conditions. Reconciling both properties requires various forms of innovations, chief among them innovations in digital public services. Building upon the four-stage model underpinning the...

• Health monitoring services based on off-the-shelf mobile devices

  Publikacja

  • W. Korłub

  - Rok 2013

  Development of health monitoring systems usually involves usage of dedicated devices with provided guarantees in terms of their reliability. Those devices raise the cost of the whole system, because of which such platforms are limited only to specific areas and constrained number of users. Usage of off-the- shelf devices could lower the cost and bring those systems to the masses. The paper covers possible uses of common off-the-shelf...

• Comparison of EHD devices with parallel and in series spiked electrodes

  Publikacja

  • J. Podlinski
  • A. Berendt
  • J. Mizeraczyk

  - Rok 2012

  In this paper two electrohydrodynamic (EHD) devices for gas pumping and cleaning are presented. In both cases to induce an airflow in these EHD devices corona discharge was used. The discharge was generated between the spiked electrodes set parallel (the first case) or in series (the second case) and the plate electrodes. An asymmetric electric field and generated discharge result in unidirectional gas flow through the EHD device....
