The relay autotuner provides a simple way of finding PID controller parameters. Even though relay autotuning is much investigated in the literature, the practical aspects are not that well-documented. In this paper an asymmetric relay autotuner with features such as a startup procedure and adaptive relay amplitudes is proposed. Parameter choices and handling of noise, disturbances, start in non-st

The quality of spatial analysis is highly dependent on the geo-referencing quality and the definition of the geographic context variables used. However, such information is seldom considered in historical demographic and epidemiological research that includes the geographic context. We investigate a suitable geographic level for geocoding of the population and definition of geographic context vari

Measuring adherence to clinical guidelines using mobile health (mHealth) technologies when form field validation is enforced or turned on could potentially be viewed as skewing the dataset, leading to 100% adherence to the clinical rule base. In theory, healthcare providers should fully abide by clinical guidelines, whether in paper or digital format, to ensure that the patient receives appropriat

The impact of BRICS (Brazil, Russia, India, China, and South Africa) and other emerging economies on the field of international development has seen traditional donor nations wrestle with fundamental shifts in the geometry and makeup of the donor community. This has resulted in asymmetrical power relations in organizations such as the Organisation for Economic Co-operation and Development (OECD) f

When the GREAT campaign was announced in 2011, we were still in theera of New Public Diplomacy, and were wrapped up in the potentialof digital media to change the diplomatic landscape. Interconnectedglobal publics were supposed to solve wicked global problems likeclimate change through inclusion and dialogue; by sharing knowledgeand working together to shape social change. The role of governmentsw

Visually guided flight control in the rainforest is arguablyone of the most complex insect behaviors: illuminationvaries dramatically depending on location[1], and the densely cluttered environment blocksout most of the sky [2]. What visual information doinsects sample for flight control in this habitat? Tobegin answering this question, we determined the visualfields of the ocelli—thought to play

Aqueous dispersions of fluorinated colloidal spheres bearing grafted poly(ethylene glycol) (PEG) are studied as a function of salt and particle concentration with the aim of improving the understanding of interactions among polymer-grafted particles. These dispersions can sustain large concentrations of salt, but crystals nucleate in dilute dispersions when a sufficient Na2CO3 concentration is rea

The Siemens SGT-800 3rd generation DLE burner fitted to an atmospheric combustion rig has been numerically investigated. Pure methane and methane enriched by 80 vol% hydrogen flames have been considered. A URANS (Unsteady Reynolds Averaged Navier-Stokes) approach was used in this study along with the k − ω SST and the k − ω SST-SAS models for the turbulence transport. The chemistry is coupled to t
