The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. As a result of these disturbances new investigations have co

I Sverige, liksom i många västeuropeiska länder, satsas stora resurser och engagemang för att locka unga män och kvinnor att söka till tekniska utbildningar. Nya inriktningar och förändrade programtitlar skapas, utbildnings- och kursplaner skrivs om, marknadsföringen vässas och mottagande och stöd till studenterna utvecklas. Trots detta tycks det gå trögt. I denna artikel argumenterar vi för att d

The Swedish composer John Fernström (1897-1961) wrote over 200 pieces in the genres of symphonic music, chamber music and vocal music for mixed choirs, male choirs and solo vocals accompanied by piano. He lived most of his life in the province of Scania, first working in Helsingborg from 1916­ 1939 as a violinist in Nordvästra Skånes Orkester- förening [the Northwest Scanian Orchestra], whereafter

The report is a preliminary study into how composite materials can be used as a lifting aid in the automotive industry. In the preliminary study are the advantages and disadvantages of using composite materials up.

Popular Abstract in Swedish Utveckling av AMS-tekniken och tillämpningar på 3H och 59Ni mätningar Traditionellt mäter man radioaktivitet genom att registrera den utsända strålningen från sönderfallande kärnor. Denna sönderfallsmätning fungerar oftast bra så länge halveringstiden (den tid det tar för hälften av kärnorna att sönderfalla) är kort nog samt då man har tillräckligt mycket material. MetAccelerator mass spectrometry (AMS) is a highly sensitive technique for counting atoms. Its main advantage in comparison with radiometric methods is the smaller amount of sample required (by a factor of a thousand). The method has a high efficiency and requires only some ten mg of sample material. The radioisotope 59Ni is of great importance in nuclear waste management in the nuclear industry. Thi

In this article I study the thought of French mathematician and philosopher Charles de Bovelles (1479-1553) on wisdom and man's place in creation.

Jordan has seen a large increase in population during the past five decades as a result of high population growth rate and forced migrations. Economical and cultural development has improved the standard of living and changed consumer habits in the community, resulting in an increase in the volume of Municipal solid waste (MSW) with time. World Bank visibility study (2004) showed that the rate of

In this article, I present evidence that Old Mongolian had preaspirated stops and affricates, like modern Halh Mongolian. The evidence consists of a number of historical phonological processes where two consonants on either side of a vowel interact with each other, and which are best explained by the assumption that the preceding consonant is postaspirated and the following one is preaspirated.

Chemical risks of consumer goods are a rather new concern in society. These risks are usually based on sythetic chemicals and man-made, often imperceptible and potentially devastating. These risks are reliant on knowledge claims and experiences as basis for risk judgments since, for example, chemical properties, threshold values and exposure are part of defining the risk. But risks are also define
