We describe the mathematical model of a digitally controlled buck converter. This model is an autonomous discrete-time
discontinuous piecewise-linear dynamical system in three dimensions. Investigating this system, we ...
Digital control of power converters has been an area of considerable research interest in recent times. One of the problems which arises in these systems is that of the limit cycle oscillations that occur due to quantization ...
The ability of docking to predict angiotensin converting enzyme (ACE) inhibitory dipeptide sequences was assessed using AutoDock Vina. All potential dipeptides and phospho-dipeptides were docked and scored. Peptide intestinal ...
Based on the formal analysis of a resonant electrostatic vibration energy harvester operating in constant-charge mode with a gap-closing transducer, we show that the system displays universal behaviour patterns. In this ...
While economic capital is not synonymous with cultural, social or symbolic capital in either its constitutional or organisational form, it nevertheless remains the more flexible and convertible form of capital. The ...
The preparation of supported and unsupported group II oxide catalysts through oxidation of analogous group II acetates (Mg, Ca and Ba) in the presence and absence of a mesoporous silica material (SBA-15) was analysed using ...
Temporal granularities are the unit of measure for temporal data, thus a multigranular temporal object model allows to store temporal data at different levels of detail, according to the needs of the application domain. ...
The response of a bridge to a pre-weighed truck can be
measured on site. This paper describes a mathematical
method for converting the measured response of a load
effect into an influence line for that effect. One ...
Crystalline titanium dioxide (TiO2) coatings have been widely used in photo-electrochemical solar cell applications. In this study, TiO2 and carbon-doped TiO2 coatings were deposited onto unheated titanium and silicon wafer ...
This paper examines the everyday lives of Northern Irish evangelicals since the Belfast Agreement of 1998. Drawing on more than 100 semi-structured interviews with evangelicals (conducted between 2002-2007), we explore the ...
