Model-based testing as a service
The quality ofWeb services is an important factor for businesses that advertise or sell their services in the Internet. Failures can directly lead to fewer costumers or security problems. However, the testing of complexWeb ...
PC-TraFF: identification of potentially collaborating transcription factors using pointwise mutual information
Abstract Background Transcription factors (TFs) are important regulatory proteins that govern transcriptional regulation. Today, it is known that in higher organisms different TFs have to cooperate rather than acting ...
Distribution and evolution of stable single α-helices (SAH domains) in myosin motor proteins
Stable single-alpha helices (SAHs) are versatile structural elements in many prokaryotic and eukaryotic proteins acting as semi-flexible linkers and constant force springs. This way SAH-domains function as part of the lever ...
Shao's theorem on the maximum of standardized random walk increments for multidimensional arrays
(EDP Sciences, 2010)
We generalize a theorem of Shao [Proc. Amer. Math. Soc. 123 (1995) 575–582] on the almost-sure limiting behavior of the maximum of standardized random walk increments to multidimensional arrays of i.i.d. random variables. ...
Calculation and optimization of thresholds for sets of software metrics
(Springer US, 2011)
In this article, we present a novel algorithmic method for the calculation of thresholds for a metric set. To this aim, machine learning and data mining techniques are utilized. We define a data-driven methodology that can ...
An alternative procedure for selecting a good value for the parameter c in RBF-interpolation
(Springer US, 2010)
The impact of the scaling parameter c on the accuracy of interpolation schemes using radial basis functions (RBFs) has been pointed out by several authors. Rippa (Adv Comput Math 11:193–210, 1999) proposes an algorithm ...
To Wait or Not to Wait? The Bicriteria Delay Management Problem in Public Transportation
Assume that a train reaches a station with delay. At the station there is a bus ready to depart. The question if such a bus should wait for the delayed train or if it should depart on time is called the delay ...
Locating a Circle on a Sphere
Locating a minisum circle in the plane
We consider the problem of locating a circle with respect to existing facilities in the plane such that the sum of weighted distances between the circle and the facilities is minimized, i.e., we approximate a set of given ...
Iterative and range test methods for an inverse source problem for acoustic waves
We propose two methods for solving an inverse source problem for timeharmonic acoustic waves. Based on the reciprocity gap principle a nonlinear equation is presented for the locations and intensities of the point sources ...
