Fibre fragment distribution in a single-fibre composite tension test

2001

Abstract Single fibre fragmentation tests are performed for brittle fibres with Weibull strength distribution and different surface treatments. The fragmentation process is modelled and closed-form expressions for break spacing distribution are obtained. The model accounts for the effect of finite fibre length on the initial fragmentation as well as for break interaction on the advanced fragmentation stage. It is assumed that the exclusion zone due to fibre–matrix interface failure and stress recovery in the fibre is linearly dependent on the applied load. This assumption is validated experimentally. The derived theoretical average fragment length dependence on applied load is used to deter…

The Impact Of Hybrid Infrastructure On Trust, Motivation And Knowledge Sharing In An Intentional Community: A Latvian Case Study

2013

The role of ICT infrastructure in enhancing innovation processes through fostering knowledge and information exchange is a controversial topic in regional science. Opposing views exist, in particular, with regard to two topics: a) the persistence of a specific role of geographical proximity in knowledge exchange processes in the age of global virtual networking; b) the capability of virtual networking to recreate the social assets of a physical community (trust, solidarity?). Existing studies primarily focus on aggregated data, rely on doubtful epistemological assumptions (e.g. the equation of information with knowledge), and neglect several epistemological principles of social cognition (e…

On the spatial configuration of scatterers for given delay-angle distributions

2014

Published version of an article in the journal: Engineering Letters. Also available from the publisher at: http://www.engineeringletters.com/issues_v22/issue_1/EL_22_1_05.pdf. Open access This paper investigates the distribution of scatterers located around the mobile station (MS) for given delay-angle distributions. The delay-angle distribution function represents the joint probability density function (PDF) of the time-ofarrival (TOA) and angle-of-arrival (AOA). Given such a joint PDF, we first derive a general expression for the distribution of the scatterers in both polar and Cartesian coordinates. We then analyze an important special case in which the TOA and the AOA follow the multipl…

Understanding Urban Fabric with the OH_FET model based on Social Use, Space and Time

2008

The proposed principle for understanding the urban fabric is based on considering the town as a set of complex objects, taking a systemic approach. The town system used to study the urban fabric over large time spans is composed of three sub-systems relating to historical objects from the level of the excavation to that of the former urban space: function (social use), space (location, surface area and morphology) and time (dating, duration and chronology). The historical object is the analytical unit of the space studied. It is the Cartesian product of the three sets, Social use, Space and Time, from which it stems. On the basis of this process, the Historical Object (OH) is broken down in…

Sharing and disseminating knowledge of advanced spatial modelling. Presentation of an action carried out by the European research group S4 (spatial s…

2006

International audience; The European research group S4 (Spatial simulation for social sciences) gathers researchers in geography as well as in geographical information sciences coming from about 30 European research centres. One action of the European research group S4 consists in sharing and disseminating knowledge of advanced spatial modelling. We propose here to describe several aspects of this action that are of interest considering the objectives of the CAENTI. The first aim of the action is to improve the diffusion of the results of the research in advanced spatial modelling, particularly in direction of regional and urban management and planning. The second aim is the development of …
