  journal article in Web of Science
  Ceramics joints are applied for producing products that should be made in a general shapes and dimensions for more advantageous usage. The article presents the research work related to ceramic joint quality evaluation, the thermal-structural analysis of ceramic joining and ceramic bond design and implementation. The role of ceramic material in the electronics industry and motivation for joining ceramics is described in the introduction. The requirements and methods for improving the quality of joints are summarized. also, the results of simulations of pressure sensor cooling after removal from the oven during joining are discussed. The experimental results are evaluated by using a t-test before and after process cooling modification. Important directions for future research are summarized, with emphasis on the statistical determination of poor connection, and how the interface of modification of joint technology and process setting affects results and parameters that have been achieved.

  The aim of this paper is to show the complex thermal analyses used for examining cooling properties of a liquid cooling system integrated into an aircraft fuel metering pump. The cooling is provided by flow of aviation fuel. The main advantage of this solution is easy implementation in the place of engine bay.

  In this paper, the author presents survey of the modern approaches in the thermal analysis of power electronic systems. The improvement and the new methods are applied to the real engineering problem. The thermal analysis based on lumped parameters thermal network (LPTN) and finite elements method (FEM) is considered in this paper. The both methods were compared in order to highlight the advantages and defects of each. In addition, an overview of the problems linked to the thermal parameter determination and computation is proposed and discussed.

  This paper describes steps involved in the design and realization of a new type of pressure sensor based on the optical fiber Bragg grating. A traditional pressure sensor has very limited usage in heavy industrial environments, explosive or electromagnetically noised environments in particular. Utilization of optics in these environments eliminates all surrounding influences. An initial motivation for our development was research, experimental validation, and realization of a complex smart pressure sensor based on the optical principle. The main benefit of this solution consists of increasing sensitivity, resistance to electromagnetic interference, dimensions, and potential accuracy.

  This project is concerned with non-convectional DC machine rotor cooling using heat pipe in the shaft. The aim was to examine the possibilities of using heat pipe for cooling of DC machine rotor winding. The heat pipe effect was tested on the real DC machine. The thermal model using finite elements method was used for the check of such cooling. The experimental measuring was used for verification of computational simulations.
