Biofeedback is a therapy currently being researched to treat many psychological and physiological disorders. EEG biofeedback involves monitoring and altering brain activity. It has been shown to effectively treat such problems as epilepsy and brain disorders. To apply this technology on a personal setting, an inexpensive and user-friendly device, capable of processing brain signals and providing logical interpretation of the recorded activity, is required. Several types of electrodes and feedback mechanisms, as well as a design for high-gain amplifiers, have been researched and analyzed. Moreover, the current design of the prototype and the anticipated future work are discussed in the following article.

This paper examines adaptive control of a special class of feedforward nonlinear systems having unknown and symmetric dead-zone input. The design strategy is based on the combination of the invariant-manifold stabilization technique with the classical adaptive compensation method. Simulation results showed that the presence of symmetric dead-zone inputs in the system dynamics can be handled even for arbitrary large dead-zone parameters.

Pumping of fluids with low Reynolds number is one of the main challenges in lab-on-a-chip and “micro total analyzer” devices. Any downscaling of channels which is used microfluidics components in such systems intensified the phenomena. Application of the electroosmotic micropumps is suitable for very low Reynolds number. In this paper a modified fabrication process presented to design an “AC electrokinetic micropump” with minimized channel geometry. The proposed device is a 4-phase travelling wave electroosmotic micropump, which is fabricated by surface micromachining technique. During the fabrication process, a thin silicon nitride layer covers the electrodes. The pumping performance is studied by presence of this thin insulator layer. This study reveals that the pump operates if the electric conductivity of fluid buffer is low. Additional advantage of the insulator layer over electrode arrays is the preventing of high electric field on electrode edges and consequently undesired chemical reactions, like electrolyze. The fabrication process and results of finite element analysis is presented. The maximum flow rate of “2.39 mm/s” is obtained at a wide frequency range.

Global Positioning System (GPS) accuracy deteriorates significantly in dense urban areas and it is almost unavailable inside buildings. Thus, an alternative accurate navigation system for such GPS-denied systems is of great importance. In this paper, the popular IEEE 802.11 WLAN (WiFi) is utilized along with a MEMS-based reduced inertial sensors system (RISS) to provide an accurate and smooth positioning system for wheeled vehicles inside buildings based on WiFi received signal strength (RSS). The WiFi/RISS integration is performed based on a fast version of Mixture Particle Filter (PF) which is a nonlinear non-Gaussian filtering algorithm that handles well the complex MEMS inertial sensors and WiFi stochastic nature. The proposed system was physically implemented on an embedded system on an OMAP 600 MHz processor board and tested on a mobile robot. Results show that drifts of RISS are greatly removed and the scattered noisy WiFi positioning is significantly smoothed. Experiments show that the integrated system can provide smooth indoor positioning of 2m accuracy 60% of time.

AUTOSAR standard has been introduced by automotive manufacturers, suppliers and tool developers to define an open automotive software architecture. This paper proposes a framework for automotive model-based design by mapping AUTOSAR concepts with a common model-based design of a steering-by-wire system. It explores how AUTOSAR rules and interfaces can be used to design and build a safety-critical mechatronics system like the steering-by-wire system. The system should be modeled from a system (e.g. controllers, network) and behavioral (e.g. Matlab/Simulink) point of view and both the functional and non-functional requirements should be verified in this model.

This study investigates the application of magneto hydrodynamics, MHD, effect in cardiovascular magnetic resonance imaging (MRI). We established a theoretical enlightenment of fluid mechanics and MHD equations. We emphasized on the application of MHD effect in cardiovascular MRI where an interpretation of MHD on ECG signals was clearly premeditated. The theory was simulated using SIMULINK™. We were able to detect the MHD noise affecting the MR-ECG. According to assumed parameters, the obtained signal amplitude allowed to obtain a correct cardiovascular signal after verifying no ST segment elevation. However, the developed exploration will facilitate the elimination of the MHD effect in cardiovascular MRI after presuming and identifying the MHD signal by using simulation.

Piezoceramics energy harvesters can transform ambient vibration energy into electrical signals and thus they are being explored for their potential to create self-powered devices for a variety of applications. However, currently available harvesters suffer from low-power outputs. This paper presents a concept of a shear mode piezoceramic energy harvester that utilizes favourable material properties to improve output power harvested from ambient mechanical vibrations. A model of this harvester is also presented to predict the power output and other characteristics of the harvester under various environments.

Modern robotic technologies have provided efficient solutions to protect workers from hazards in the work environments; such as radioactive, toxic, or explosive. This paper presents a design of a holonomic mobile robot for rough terrain that can replace the human role in the demining applications. A suspension system based on the bogie mechanism was adopted in order to overcome rough terrains. The flexible design of the robot enables it to move in any direction at any instant without changing the orientation of the body. The motion of the robot was simulated using the Pro-Engineer software and the robot stability margins for different road conditions were found in order to predict the possibility of tipping-over before any maneuver.

At present the most popular navigation system in the world is Global Positioning System (GPS). As it is managed by the Department of Defence of the U.S.A., there is always the risk of the occasional inaccuracies or deliberate insertion of errors, therefore this system can not be used by secret services or armies of countries other than the U.S.A. This situation has engender a need for development of an autonomous radiolocation system. This article describes the construction and operation of such a system technology demonstrator which was developed at the Gdańsk University of Technology (GUT). It was named AEGIR (god of the ocean in Norse mythology). This paper presents results and analysis of its effectiveness.
