A straight-forward design of graphic equalizers with minimumphase behavior based on recently developed higher-order bandshelving filters is presented. Due to the high filter order, the gain in one band is almost completely independent from the gain in the other bands. Although no special care will be taken to design filters with complementary edges except for a suitable definition of the cut-of...

The other technique is to learn some form of control knowledge, which helps to determine which control action to try next. Ideally the former “blind” search with exponential complexity is replaced by a strategy to move straight forward in direction of the goal. The control knowledge can take many forms including evaluation functions, operator strengths, and operator-selection and rejection rule...

Partial differential equations are a convenient way to describe reactionadvection-diffusion processes of signalling models. If only one cell type is present, and tissue dynamics can be neglected, the equations can be solved directly. However, in case of multiple cell types it is not always straight forward to integrate a continuous description of the tissue dynamics. Here, we discuss (delayed) ...

The so-called self consistency method uses the fact that the true radar co-polar reflectivity (Zh e) and the differential reflectivity (Zdr ) can be used to predict the specific differential propagation phase (Kdp) at each radar range gate. The application of this method at S-band is relatively straight-forward as has been demonstrated in the past (e.g. Goddard et al., 1994). At C-band, one nee...

Durable goods are an important component of the business cycle. Equilibrium models of durable goods markets are made difficult by the lumpy nature of individual purchases. We show that a straight forward approximation of the distribution of durable goods holdings gives rise to a tractable equilibrium model. We analyze the case of competition as well as that of a monopoly producer. J.E.L. Classi...

First rather straight forward estimates for sublimation in a vacuum are discussed, and then diffusion in a stationary He atmosphere is calculated. But a He atmosphere with large temperature gradients will not be stationary in the presence of gravity, as was correctly pointed out by several colleagues [2]. Crude but safe convection estimates are then presented. Finally the idea of possible chemi...

We calculate the rapidity dependence of leading-order medium dilepton yields resulting from a quark-gluon plasma which has a local time-dependent anisotropy in momentum space. We present a phenomenological model which includes temporal evolution of the plasma anisotropy parameter, ξ, and the hard momentum scale, phard. Our model interpolates between 1+1 dimensional collisionallybroadened expans...

Understanding emerging trends and patterns in science and technology is essential not only to scientists and engineers in their own fast-advancing fields but also to a wide variety of individuals and organizations who are also interested in tracking the development of thematic topics. This is a challenging task because many existing tools are not particularly designed to deal with the dynamics ...

OBJECTIVE: The aim of this randomized clinical trial was to evaluate the dental, dentoalveolar, and skeletal changes occurring right after the rapid maxillary expansion (RME) and slow maxillary expansion (SME) treatment using Haas-type expander. METHODS: All subjects performed cone-beam computed tomography (CBCT) before installation of expanders (T1) and right after screw stabilization (T2)....
