Abstract: Transient analysis is an important circuit simulation technique. The circuit model, which is a system of differential-algebraic equations, is solved for a given initial condition using numerical time integration techniques. Multirate methods are efficient if the dynamical behaviour of the circuit model is not uniform. This paper deals with the analysis and control of the discretizatio...

The concepts of stability regions, Aand A(α)-stability – albeit based on scalar models – turned out to be essential for the identification of implicit methods suitable for the integration of stiff ODEs. However, for multistep methods, knowledge of the stability region provides no information on the quantitative stability behavior of the scheme. In this paper we fill this gap for the important c...

The potential of the hybridized discontinuous Galerkin (HDG) method has been recognized for the computation of stationary flows. Extending the method to instationary problems can, e.g., be done by backward difference formulae (BDF) or diagonally implicit Runge-Kutta (DIRK) methods. In this publication, we investigate the use of embedded DIRK methods in an HDG solver, including the use of adapti...

I. Fasted dog serum non-ester&d fatty acid (NEFA) levels were elevated to and 34 hours after administration of a diabetogenic protein (BDF) isolated from bovine adenohypoph+L 2. The fasting serum NEFA were elevated in spite of the presence of normal or high glucose and insulin Icvels. 3. After oral glucase administration to BDF-treated animals, a fall of serum NEFA paralleled inversely the incr...

We propose a new discretization method for PDEs on moving domains in the setting of unfitted finite element methods, which is provably higher-order accurate space and time. In considered setting, physical domain that evolves essentially arbitrarily through time-independent computational background represented by level set function. For time discretization, application standard stepping schemes ...

It has been more than a decade since emergency medicine became recognized as a specialty in the Kingdom of Bahrain. In the last fifteen years emergency medicine has widely established itself and developed rapidly in the Kingdom. The three main emergency departments are: Salmanyia Medical Complex (SMC), Royal Medical Services of Bahrain Defence Force (RMS-BDF) and King Hamad University Hospital ...

Worldwide, military personnel have been recognized as a population at elevated risk for sexually transmitted infections (STIs) and HIV; however, it is not well understood how the military occupation itself is implicated in the production of sexual risk behavior. Using qualitative and quantitative data collected from the Belize Defense Force (BDF), we employed a grounded theoretical framework an...
