Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...

in order to determine the relationship between knowledge, attitude and health behaviour among menopausud women, a random sample of 250 menopaused women was studied. the data was collected by using a questionnaire and analysed by the spss programe. the study showed that seventy woman (28%) had good knowledge, only twenty seven women (11%) had a positive attitude, and forty women (16%) had good h...

This paper extends the Function-Behaviour-Structure (FBS) framework, which proposed eight fundamental processes involved in designing. This framework did not explicitly account for the dynamic character of the context in which designing takes place, described by the notion of situatedness. This paper describes this concept as a recursive interrelationship between different environments, which, ...

This paper proposes a comprehensive schema to represent an agent’s social knowledge using the Function – Behaviour – Structure (FBS) schema. Although this schema has originally been developed to represent knowledge about design objects, it is sufficiently abstract to also describe knowledge about agents. This paper shows how such an FBS view can be useful to support the interaction of situated ...

This paper presents the beginnings of a formal framework to enhance our understanding of situated design agents. It builds on the function-behaviour-structure (FBS) schema to represent essential concepts of situated designing. Our framework covers different stages in the life-cycle of situated design agents, including their development, testing and usage.

Nowadays, t he bi otechnologically pr oduced p olymers, e .g. p oly(3hydroxyalkanoates) (PHAs), a re widely used for biomedical ap plications ( e.g. in t issue e ngineering), because of bi odegradation a nd high biocompatibility. PHAs are used for development of various medical devices. These biopolymers can be also used for development of experimental models, e.g. 3D cell culture model. To dev...

The use of detailed models for bioprocess design and control has been limited as accurate estimation of model parameters is often difficult. In this paper, the parameter estimation problem for a mechanistic model of the production of a biopolymer, poly-β-hydroxybutyrate (PHB), is examined in detail. Parameter estimation was undertaken using previously published data. Three parameter sets were o...

The change in the actual use of buildings by its occupants is receiving more and more attention. Over the lifecycle of a building the occupants and therefore the demands towards the buildings often change a lot. To match these altering conditions, particularly in the context of the demand for energy efficiency, purely technical approaches usually cannot solve the problem on their own or are not...
