Adsorption-desorption phase noise in RF MEMS/NEMS resonators
(10th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting, 2011)
In this paper the analysis is presented of the dependence of adsorption-desorption phase noise in MEMS/NEMS resonators of their resonant frequency, operating pressure and temperature. Results of the analysis are useful for ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
Design of symmetric planar fishnet metamaterials for optical wavelength range
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
In this work we analyze fishnet-type optical metamaterials with full electromagnetic symmetry, fabricated in an ultrathin, freestanding film (self-supported nanomembrane). We utilized the finite element method to simulate ...
Zinc removal from Bayer liquor by using aluminium hydroxide with specific structural properties as crystallization agent
(Association of Technology Engineers of Republic of Srpska, 2018)
The presence of Zn compounds in alumina reduces the current efficiency during electrolysis and quality of obtained metal. The known methods for Zn compounds removal that involves the use of different chemical agents (e.g. ...
Teaching optics: Preuniversity level
(19th Telecommunications Forum, TELFOR 2011 - Proceedings of Papers, 2011)
This paper presents the expirience of introducing the Optics Suitcase, a portable kit for demonstrating optics to students, developed at the Institute of Optics in Rochester, to high school children following experimental ...
Analytical modelling of transient processes in thermal microsensors
(12th Int. Conf. on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microele, 2011)
An analytical method is developed to determine the frequency response of thermal microsensors on various input actions. The method has the following algorithm. In a microsensor, the domain of modelling is marked out. This ...
Decopperization process of waste solutions from conventional copper electrolysis
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
This paper is adresses on treatment of sulphuric acid waste solutions obtained during the conventional copper metallurgical activities. Mother liquor is a part of this solutions and it is generated during the regeneration ...
CAD/CAM tools in risk analysis during designing process
(University of Belgrade, Faculty of Mechanical Engineering, 2018)
By definition, the risk represents suspense in relation to the desired outcomes. According to that, this project includes the algorithm which with the help of the tool CAD/CAM provides step analysis in the process of ...
AC Impedance tracking of glassy carbon activation
(Serbian Chemical Society, Belgrade, 2010)
Carbon materials, due to their physical and chemical properties, have found wide application in different electrochemical systems. They are often used as substrates for supercapacitors and different types of electrocatalysts. ...
