Selected Reaction Monitoring (SRM) is a powerful tool for targeted detection and quantification of peptides in complex matrices. An important objective of SRM is to obtain peptide quantifications that are (1) suitable for the investigation, and (2) reproducible across laboratories and runs. The first objective is achieved by system suitability tests (SST), which verify that mass spectrometric i...

We analyse the biases of eleven mtasures for estimating the quality of the mult ivalued attributes The values of information gain Jmeasure, gini-index and relevance tend to lin early increase with the number of values of an attr ibute The values of gam-ratio dis tance measure, Relief and the weight of evidence decrease for informative attributes and increase for irrelevant attributes The bias o...

We investigate reliable multicast communication over satellite networks. We compare a scenario where receivers can use a feedback channel to signal loss to a scenario where no feedback channel is available. We show that the introduction of a feedback channel is the key to allow for bandwidth-eecient, robust, and fully reliable multicast communication via satellite.

Context: Software products have requirements on various software quality attributes such as safety and performance. Development teams use various specific techniques to achieve these quality requirements. We call these “Quality Attribute Techniques” (QATs). QATs are used to identify, analyse and control potential product quality problems. Although QATs are widely used in practice, there is no s...

Traditionally, the statistical quality control techniques utilize either an attributes or variables product quality measure. Recently, some methods such as three-level control chart have been developed for monitoring multi attribute processes. Control chart usually has three design parameters: the sample size (n), the sampling interval (h) and the control limit coefficient (k).The design parame...

There is a growing scientific consensus that COVID-19 could be transmitted through the airborne route, putting ventilation at heart of mitigation strategy for buildings, including schools. The design suitable systems requires to consider all aspects both control air movement and diffusion bacterial loads, but also other parameters indoor quality. This work examines acoustic in schools effects h...

For advanced streaming applications over wired-wireless networks TCP-Friendly Rate Control (TFRC) has been widely adopted nowadays to give smooth sending rate and unceasing quality in streaming applications TFRC applies an equation-based rate control scheme. However, TFRC tends to fail in wireless environment if packet lost event was done by poor channel quality but network congestion. Therefor...

The combinatorial match in production systems (rule-based systems) is problematical in several areas of production system application: real-time performance, learning new productions for performance improvement, modeling human cognition, and parallelization. The unique-attribute representation is a promising approach to eliminate match combinatorics. Earlier investigations have focused on the a...

Techniques and tools for specific quality-attribute issues are becoming a mainstream in architecture design. This approach is practical for evaluating the architecture in early stages but also for planning improvements for it. Thus, we believe that one challenge is the integration of the individual capabilities of quality-attribute techniques. This paper presents our research work on a design a...

For all M,N∈P(U) such that M⊂N, we first introduced the definitions of (M,N)-uni-soft ideals and (M,N)-uni-soft interior ideals of an ordered semigroup and studied them. When M=∅ and N=U, we meet the ordinary soft ones. Then we proved that in regular and in intra-regular ordered semigroups the concept of (M,N)-uni-soft ideals and the (M,N)-uni-soft interior ideals coincide. Finally, we introduc...
