Current trends observed in air pollution control technology are closely related to the development of new, more efficient hybrid systems, i.e., those, which simultaneously utilize two or more physical mechanisms for dust or gaseous contaminants removal. These systems can operate more economically than conventional devices, especially in the removal of PM2.5(More)
In this paper we propose a fast brain computer interface speller based on electroencephalography (EEG). The slow performance of conventional BCI spellers is overcome by combining the fast motor evoked potentials (MEPs) with the accuracy of P300 event related potentials. The μ rhythms associated with motor imagery are extracted using morlet wavalet(More)
The purpose of this paper is to determine whether it is possible to use an automated measurement tool to clinically classify clients who are wheelchair users with severe musculoskeletal deformities, replacing the current process which relies upon clinical engineers with advanced knowledge and skills. Clients' body shapes were captured using the Cardiff Body(More)
The purpose of the paper is to briefly review some of the methods used to obtain aerosol bipolar charge distribution and to describe a novel instrument developed at Brunel University. The bipolar charge aerosol classifier (BCAC) is an improved version of the authors' previously published bipolar charge measurement system (2001), eliminating some of his(More)
The purpose of this paper is to present the design and implementation of a novel rule-based algorithm for the classification of sitting postures in the sagittal plane. The research focused on individuals with severe musculoskeletal problems and, thus, specific requirements for posture and pressure management. Clients' body shapes were captured using the(More)
The proposed noninvasive method of measurement of the charge level on a population of particles employs the phase Doppler anemometry (PDA) technique in conjunction with a high-resolution computer controlled traversing system. The PDA system was used to track the motion of charged particles in the presence of a DC electric field. By solving the equation of a(More)
This paper describes an integrated signal processing system based on Quadrature Demodulation (QD) and correlation techniques to obtain particle size and charge simultaneously using phase Doppler anemometry (PDA). By solving the equation of particle motion in an AC electric field combined with the measurement of its size and velocity, the magnitude as well(More)
An array of microelectrodes was supplied with a dual-frequency electrical signal to create a non-uniform electric field that was used for a dielectrophoretic particle transport system. Dielectrophoretic force was used to convey sub-micron sized particles along the tips of electrodes. The particles were manipulated along an arrangement of fabricated(More)
