Flow through mixed flow compressor stage was evaluated theoretically to understand internal flow behaviour. Various shroud configurations in terms of clearance has been considered to see the effect of clearance on compressor performance. The blade to blade relative flow variation from impeller inlet to outlet was evaluated through theoretical analysis. A 3D viscous commercial code Fluent was us...

Abstract Once a software product is delivered to a customer, the quality of service provided plays an important role in retaining that customer. In this paper, we identify certain key factors that impact the service quality in...

Television advertising is widely used by companies to promote their products among the public but it is hard for an advertiser to know if its advertisements are broadcast as they should. For this reason, some companies are specialized in the monitoring of audio/video streams for validating that ads are broadcast according to what was requested and paid for by the advertiser. The procedure for s...

Safety-critical systems are becoming more widespread, complex and reliant on software. Increasingly they are engineered through Commercial Off The Shelf (COTS) (Commercial Off The Shelf) components to alleviate the spiralling costs and development time, often in the context of complex supply chains. A parallel increased concern for safety has resulted in a variety of safety standards, with a gr...

This paper presents an empirical research to study synchronous and asynchronous collaborative design in a technology-mediated situation. In this experiment we wanted to create a design situation where four distant designers had to communicate using commercial software and standard hardware configurations. Our methodological approach gave us the opportunity to examine two main lines of research ...

The main objective of this thesis is to provide radio-oncology specia-lists with automatic tools for delineating organs at risk of a patient undergoing aradiotherapy treatment of cerebral or head and neck tumors.To achieve this goal, we use an anatomical atlas, i.e. a representative anatomyassociated to a clinical image representing it. The registration of this atlas allowst...

Understanding causal relationships on incident management can help software development organizations in finding the adequate level of resourcing, as well as improving the quality of services they provide to their end-users and/or customers. This paper presents an empirical study conducted upon a sample of incident reports recorded during the operation of several hundred commercial software pro...

Packaged software development (PSD) is largely a knowledgeintense activity. Thus, it depends on the organizational capability of developing and combining market and technical knowledge into timely and competitive software products. Given customers’ situated knowledge of the software, software firms increasingly seek new ways to involve customers in their software development activities. As high...

The objectives of this study are to learn more about generic and specific requirements for automated map generaliz...

Commercial software firms are increasingly becoming involved with open source communities. In this research-in-progress paper I briefly analysed a single firm case that demonstrates how an institutional entrepreneur mixes in an innovative way different discourses in an attempt to legitimise a new mode for developing software applying both open and closed source codes. The institutional entrepre...
