Many embedded systems for vehicles and consumer electronics critically depend on efficient, reliable control software, and practical methods for their production. Component-based software engineering for embedded systems is currently gaining ground since variability, reusability, and maintainability are efficiently supported. However, existing tools and methods do not guarantee efficient resour...

Performing rescuing and surveillance operations with autonomous ground and aerial vehicles become more and more apparent task. Involving unmanned robot systems allows making these operations more efficient, safe and reliable especially in hazardous areas. This work is devoted to the development of a cost-efficient micro aerial vehicle in a quadrocopter shape for developmental purposes within in...

We do not assume, however, that broadcasts are reliably delivered. (One might consider providing a reliable datagram broadcast protocol as a layer above IP.) It is quite expensive to guarantee delivery of broadcasts; instead, what we assume is that a host will receive most of the broadcasts that are sent. This is important to avoid excessive use of broadcasts; since every host on the network de...

An expedient synthesis of N-unsubstituted 1,2,3-triazole-4-carboxylates has been demonstrated through [3 + 2] cycloaddition of sodium azide with α-haloacrylates. The process is highly reliable and exhibits an unusually wide scope with respect to α-fluoro-, α-chloro-, α-bromo-, and α-iodoacrylates. The potential of selected 1,2,3-triazole-4-carboxylates in the preparation of 1,5-dihydro-4H-[1,2,...

Promoting quality of life in older age is an internationally recognized priority, requiring valid measurement. We present a short version of the established Older People's Quality of Life questionnaire (OPQOL-brief). The full OPQOL-35 was original in being developed from the perspectives of older people, assessed conceptually, and validated with a population sample using gold-standard psychomet...

AIM This study aimed to determine the reliability and sex and age-level differences of body-sway parameters, based on center of pressure (COP) measurements, during a static upright posture in the elderly and to clarify their body-sway characteristics in comparison with those of young adults. METHODS The subjects were 50 healthy elderly and 50 healthy young adults. They had no evidence or know...

A sensitive, specific and precise procedure for the measurement of serum gentamicin by radioimmunoassay is presented. The method is rapid, convenient, and highly reliable for this very important measurement. Studies designed to evaluate the validity and reproducibility of the assay are presented and discussed.

A sensitive, specific and precise procedure for the measurement of digoxin by radioimmunoassay is presented. The method is rapid, convenient and highly reliable for this very important measurement. Studies designed to evaluate the validity and reproducibility of the assay are presented and discussed.
