The ability to represent knowledge about space and its position therein is crucial for a mobile robot. To this end, topological and semantic descriptions are gaining popularity for augmenting purely metric space representations. In this paper we present a multi-modal place classification system that allows a mobile robot to identify places and recognize semantic categories in an indoor environm...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...

Trust is essential to a communication channel. The trust relationships, which play an important role in Public Key Infrastructures (PKIs), need to be formalized for providing a reliable modelling methodology to support secure digital communications. In this paper, we present a typed modal logic used for specifying and reasoning about trust in PKIs. In order to study trust relationships within P...

We consider a calculus of resources and processes as a basis for modelling decision-making in multi-agent systems. The calculus represents the regulation of agents’ choices using utility functions that take account of context. Associated with the calculus is a (Hennessy–Milner-style) contextsensitive modal logic of state. As an application, we show how a notion of ‘trust domain’ can be defined ...

the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...

introduction: neuro-plasticity is the neuronal system ability to modify and recover itself after the occurrence of impairment and injuries. following the abolition of a sensory modality, modifications will be applied to other modalities and their cortical function in a way that the processing of these modalities not only will happen in their own specific cortical area, but also in those areas t...

marine industry requires continued development of new technologies in order to produce oil. an essential requirement in design is to be able to compare experimental data from prototype structures with predicted information from a corresponding analytical finite element model. in this study, structural model updating may be defined as the fit of an existing analytical model in the light of measu...

In this study, the vibration of cracked plates is investigated using the differential quadrature method and experimental modal analysis. The crack, which is assumed to be open, is modeled by the extended rotational spring. With its finite length, the crack divides the plate into six segments. Then, the differential quadrature is applied to the governing differential equations of motion and the ...
