Multioccupant Activity Recognition in Pervasive Smart Home Environments

been the center of lot of research for many years now. The aim is to recognize the sequence of actions by a specific person using sensor readings. Most of the research has been devoted to activity recognition of single occupants in the environment. However, living environments are usually inhabited by more than one person and possibly with pets. Hence, human activity recognition in the context of multi-occupancy is more general, but also more challenging. The difficulty comes from mainly two aspects: resident identification, known as data association, and diversity of human activities. The present survey paper provides an overview of existing approaches and current practices for activity recognition in multi-occupant smart homes. It presents the latest developments and highlights the open issues in this field

Hemisinteza derivata tiona i tiola iz eteričnog ulja biljke Artemisia judaica L. i antimikrobni testovi

The applications of organosulfur compounds, especially thioketones are varied which concerns both synthetic and biological chemistry. In this context, from the essential oil of Artemisia judaica L., extracted by hydrodistillation, and consisting mainly of piperitone (91.77 %), thione, and thiol derivatives were hemi-synthesized via a thionylation reaction byphosphorus pentasulphide (P2S5). The possible thione-thiol tautomerism in solution followed spectrophotometrically revealed the predominance of thiol form in solution. The antimicrobial activity of essential oils showed that the thionylation of essential oil caused a considerable increase in antimicrobial activity in particular against Escherichia coli.

Moguća tion-tiolna tautomerija praćena je spektrofotometrijski. Analiza je pokazala da u otopini dominira tiolni oblika. Također, pokazalo se da tionilacija eteričnog ulja uzrokuje znatno povećanje antimikrobne aktivnosti, osobito kad je u pitanju bakterija Escherichia coli.
