Als Ausgründungsprojekt der HTW Dresden wird mit fodjan eine webbasierte Fütterungssoftware für die Milchviehhaltung entwickelt, welche erstmals direkt die Futtergesundheit in die Kalkulation mit einbezieht. Gleichzeitig wird ein umfassender Überblick zu den verschiedenen Möglichkeiten der Futtermittelzusammenstellung gegeben. Der Anwender wird somit in der Lage sein, die beiden großen Ziele ho...

Ein Constraint Satisfaction Problem (CSP) besteht aus Variablen, Wertebereichen und Constraints, die die Belegungskombinationen der Variablen einschränken. Wir zeigen, wie man CSPs mit Hilfe von Pr/T-Netzen modellieren und lösen kann. In den verwendeten Netzen gibt es neben den konventionellen Stellenmarken Transitionsmarken, die sich entgegen der Kantenrichtung bewegen, wenn Stellen schalten. ...

Accurate and timely diagnosis of dengue virus (DEN) infections is essential for the differential diagnosis of patients with febrile illness and hemorrhagic fever. In the present study, the diagnostic value of a newly developed immune-complex dissociated nonstructural-1 (NS-1) antigen dot blot immunoassay (DBI) was compared to a commercially available DEN antigen detection kit (denKEY Blue kit; ...

Dengue is a mosquito borne disease caused by any of the four serotypes of dengue virus. Dengue 4 virus (DEN-4) was once the predominant serotype found in Malaysia causing up to 60% of dengue fever (DF) cases in 1960'sl. Since then, however, other serotypes notably DEN-2 and DEN-3 have become the predominant serotypes isolated among DF and dengue hemorrhagic fever (DHF) patients. DEN-4 made up o...

Animal populations are not constant in space and time but reveal temporal oscillations. Since the beginning of the 20th century this is a widely accepted fact [Elton, 1924, Lotka, 1925, Volterra, 1926]. Volterra [1931] and Lotka [1934] suggested the first mathematical predator-prey model for describing these oscillations. Within the following decades many different new models have been proposed...

Im nutzungszentrierten Design werden Personas als zentraler Teil des Gestaltungsprozesses genutzt. Um zu untersuchen, welche Rolle Personas beim Fortschreiben bestehender Geschlechterstereotype spielen, wurden in einer empirischen Analyse 170 Persona-Beschreibungen hinsichtlich des dargestellten sozialen Umfelds, der Freizeitbeschäftigungen und der Technikkompetenz untersucht. Die Ergebnisse ze...

We have constructed a chimeric yellow fever/dengue (YF/DEN) virus, which expresses the premembrane (prM) and envelope (E) genes from DEN type 2 (DEN-2) virus in a YF virus (YFV-17D) genetic background. Immunization of BALB/c mice with this chimeric virus induced a CD8 T-cell response specific for the DEN-2 virus prM and E proteins. This response protected YF/DEN virus-immunized mice against let...

We describe a design prototype for a virtual bookshelf which transfers characteristics of the interaction with books as physical artifacts into the digital medium. We focus on the actual visual presentation and arrangement of books. The virtual bookshelf is intended as a tool for advancing Personal Information Management (PIM). 1. Motivation und Kontext Mit der Verfügbarkeit digitaler Dokumente...

During emergency situations of the patient in home-based care, a Pervasive Healthcare Monitoring System (PHMS) (Lee et al., 2008) is significantly overloaded with pieces of information of different known reliability or unknown reliability. The pieces of the information should be processed, interpreted, and combined to recognize the situation of the patient as accurate as possible. In such a con...

The den use of possums (Trichosurus vulpecula) may be density dependent, meaning that individuals change their denning behaviour in response to changes in population density. Increases in den use due to changes in density may result in increases in bovine tuberculosis (Mycobacterium bovis; bTB) transmission among possums, as infection has previously been correlated with den use. In this study, ...
