Analog circuits are often specified using non-linear equations, which are difficult to analyze. Therefore, test generation and diagnosis are problematic issues in practice. In this paper we propose a new method for diagnosis of analog circuits that uses combined information from tests at different frequencies. By solving simultaneously the resulting equations (one for each test frequency), we get

Wave splitting of the time dependent Maxwell's equations in three dimensions with and without dispersive terms in the constitutive equation is treated. The procedure is similar to the method developed for the scalar wave equation except as follows. The up-and down-going wave condition is expressed in terms of a linear relation between the tangential components of E and H. The resulting system of d

To combat the increasing soft error rates in recent semiconductor technologies, it is important to employ fault tolerance techniques. While these techniques enable correct operation, they introduce a time overhead, which may cause a deadline violation in real-time systems (RTS). Since correct operation for RTS is defined as producing correct outputs while satisfying time constraints (deadlines), i

The new NERICA upland rice varieties were developed in Africa for Africa so as to address the continental-wide rice cereal challenge, poverty and food insecurity. To date, the ‘success’ of the dissemination of NERICA amongst smallholder farmers has mainly been established econometrically by measuring production growth or household income gain. This type of analysis allows for capturing shifts in i

Modelling is a fairly mature technology that is already being adopted by industry. Unfortunately the tools for supporting Model-Driven Engineering are not at the same level of maturity. In particular merge tools that are an important help for collaboration lack a lot to be desired in providing the support that is needed on industrial projects. Current model merge tools and research approaches focu

We evaluate the Swedish inflation targeting regime adopted in 1993-1995 using a novel approach based on a unique data set on the characteristics of collective wage agreements between 1908 and 2008. We find that the inflation targeting regime of 1995-2008 stands out as an exceptionally stable policy regime as judged by the willingness of wage contract-makers to repeatedly commit to three-year non-i

LTH har tidigare rapporterats vara den del av Lunds universitet som är svårast att vara på för homo- och bisexuella studenter. Syftet med den här undersökningen är att öka kunskapen om hur heteronormativiteten tar sig uttryck på LTH. I oktober 2011 mailade jag ut frågor som besvarades av 8 LTH-studenter, samtliga identifierar sig som homo-sexuella. Deras berättelser och erfarenheter ligger till gr

In making capacity estimates and cost calculations in the manufacturing industry, many products and production systems are often involved, making the data in their totality difficult to grasp. Introducing the concept of the characteristic part, which is a fabricated part seen as representative of all parts produced in terms of demand, setup time, cycle time, average batch size and total number of

De förenade målen C-92/09 och C-93/09, Volker und Markus Schecke, gäller uppgifter som jordbruksstöd till enskilda bönder som publicerats på internet. Målen avser en rad frågor från en tysk domstol som tagit en klart kritisk ställning till hur EU:s sekundärrätt har utformats i förhållande till skyddet för privatliv och skyddet för personuppgifter. EU-domstolen ansåg att kritiken (åtminstone delvis

Abstract in UndeterminedIn the humanitarian context, gender mediates access to aid. The gender of the beneficiary is not only intrinsically linked with her/his disaster vulnerability (Enarson, 2002), but also to their ability to physically access aid distribution points (Lutz and Gady, 2004) and even to be considered a beneficiary in the first place. There is, however, yet another factor mitigatin
