An adaptive regulator with a smoothly variable high-order linear response controlled by a single real parameter, or a regulator including a single nonlinear element, is employed in an acquisition-tracking system. The requirement for good tracking is not compromised by the requirement for fast acquisition, and vice versa. The minimum phase character of the return ratio is preserved in a robust m...

Parental education is the strongest measured predictor of offspring education, and thus many scholars see the parent-child correlation in educational attainment as an important measure of social mobility. But if social changes or policy interventions are going to have dynastic effects, we need to know what accounts for this intergenerational association, that is, whether it is primarily environ...

Wife inheritance, a tradition wherein a widow remarries her late husband’s brother, is increasingly being rejected by widows who live where the custom is practiced. Within these regions, the high prevalence and regional variation in HIV rates help to explain the decline in remarriage. Widows who reject wife inheritance are more likely to enroll their children in school, while child school enrol...

In recent years, there has been an increasing interest in the adoption of emerging sensing technologies for instrumentation within a variety of structural systems. Wireless sensors and sensor networks are emerging as sensing paradigms that the structural engineering field has begun to consider as substitutes for traditional tethered monitoring systems. A benefit of wireless structural monitorin...

Virtual Science: Virtuality and Knowledge Acquisition in Science and Cognition Markus F. Peschl and Alexander Riegler The focus of this paper is the process of knowledge acquisition (KA) and which role virtuality plays in this context. We argue that there are three different modes of knowledge acquisition which can be identified both in the domains of cognition and science: the empirical, the “...

Similarly, quadrupole time-of-flight MS (QTof) platforms continue to increase in resolving power (resolution) while maintaining the rapid scanning rate that time of flight instruments are well known for. MS data acquisition (simultaneous acquisition of full scan and all fragment ions), a generic approach to screening for metabolites has been refined for over a decade. Similar “all-ion” modes of...

Wind turbine failure and downtime can often compromise the profitability of a wind farm due to their high impact on the operation and maintenance (O&M) costs. Early detection of failures can facilitate the changeover from corrective maintenance towards a predictive approach. This paper presents a cost-e↵ective methodology to combine various alarm analysis techniques, using data from the Supervi...

We use multi-channel analysis of surface waves (MASW) on seismic data in an attempt to test data acquisition parameters and compare those results to reaffirm existing general theoretical recommendations and rules of thumb. Of particular interest were optimum seismic receiver spread size, minimum and maximum receiver offsets and dominant geophone frequency for best-case fundamentalmode dispersio...
