Improved atomic data for iridium atom (Ir I) and ion (Ir II) and the solar content of iridium

From a combination of radiative lifetime measurements, performed with a time-resolved laser-induced fluorescence technique, for nine odd-parity levels of Ir I and four odd-parity levels of Ir II and branching fraction calculations, extended sets of transition probabilities have been derived for transitions of astrophysical interest. The new results are compared with the few experimental data avail

Strictly Positive Real Problem with Observers

We study the extension of what class of linear time invariantplants may be transformed into SPR systems introducingan observer. It is shown that for the open loopstable systems a cascaded observer achieves the result.For the open loop unstable systems an observer-basedfeedback is required to success. In general any system stabilizableand observable may be transformed into an SPRsystem. This overco

Streptococcal cell surface proteins : structure and gene characterisation

Streptococcus pyogenes (group A streptococci, GAS) is a potent human pathogen known to express a number of cell surface associated virulence factors. It is an established fact that these different surface proteins play an important role during infection. Thus, M family proteins interact with host immune system components allowing streptococci to evade phagocytosis. Another important group of bacte

What Else is New Than the Hamming Window? Robust MFCCs for Speaker Recognition via Multitapering

Usually the mel-frequency cepstral coefficients (MFCCs) are derived via Hamming windowed DFT spectrum. In this paper, we advocate to use a so-called multitaper method instead. Multitaper methods form a spectrum estimate using multiple window functions and frequency-domain averaging. Multitapers provide a robust spectrum estimate but have not received much attention in speech processing. Our speake

Double-Hamming based QC LDPC codes with large minimum distance

A new method using Hamming codes to construct base matrices of (J, K)-regular LDPC convolutional codes with large free distance is presented. By proper labeling the corresponding base matrices and tailbiting these parent convolutional codes to given lengths, a large set of quasi-cyclic (QC) (J, K)-regular LDPC block codes with large minimum distance is obtained. The corresponding Tanner graphs hav

Sampling, sample treatment, assay and real time monitoring of biotechnological processes using an integrated flow-injection system

Popular Abstract in English Microorganisms can be used for production of pharmaceutical substances. With the introduction of gene technology, it is possible to transfer information from one organism to the other, thereby making the receiving organism capable of producing substances that it did not so before. This development is very important for e.g. production of therapeutic proteins However, whMicroorganisms can be used for production of pharmaceutical substances.

Requirements management for continuous software product development

Continuous software product development is increasingly becoming the norm. New requirements come in a constant stream and need to be assigned to projects to make it into a release. However, in the literature requirements management practices are project based and no longer naturally fit to this new setting. Aim: Thus, it is of interest to understand the industrial practices for the identification
