View Planning Approach for Automatic 3D Digitization of Unknown Objects
2012
International audience; This paper addresses the view planning problem for the digitization of 3D objects without prior knowledge on their shape and presents a novel surface approach for the Next Best View (NBV) computation. The proposed method uses the concept of Mass Vector Chains (MVC) to define the global orientation of the scanned part. All of the viewpoints satisfying an orientation constraint are clustered using the Mean Shift technique to construct a first set of candidates for the NBV. Then, a weight is assigned to each mode according to the elementary orientations of its different descriptors. The NBV is chosen among the modes with the highest weights and which comply with the rob…
Using crowdsourcing for a safer society: When the crowd rules
2020
Neighbours sharing information about robberies in their district through social networking platforms, citizens and volunteers posting about the irregularities of political elections on the Internet, and internauts trying to identify a suspect of a crime: in all these situations, people who share different degrees of relationship collaborate through the Internet and other technologies to try to help with or solve an offence. The crowd, which is sometimes seen as a threat, in these cases becomes an invaluable resource that can complement law enforcement through collective intelligence. Owing to the increasing growth of such initiatives, this article conducts a systematic review of the litera…
An empirical study of performance using Clone & Own and Software Product Lines in an industrial context
2021
Abstract Context: Clone and Own (CaO) is a widespread approach to generate new software products from existing software products by adding small changes. The Software Product Line (SPL) approach addresses the development of families of products with similar features, moving away from the production of isolated products. Despite the popularity of both approaches, no experiment has yet compared them directly. Objective: The goal of this paper is to know the different performances of software engineers in the software products development process using two different approaches (SPL and CaO). Method: We conducted an experiment in the induction hobs software environment with software engineers. …
RDF-Based Web Information Integration System: A Travel System Use Case
2018
Enterprises are continually faced with the challenge of integrating heterogeneous systems with incompatible interfaces, data structures (Source structured relational databases, semi-structured sources, XML, or unstructured documents: texts), access mode and technologies. When companies adopt SOA (Service Oriented Architecture), that provides an alternative to traditional design of applications by allowing a designer to assemble and compose existing services that implement the functions of a given application domain, they realize that there is a significant risk that Web services only do not solve the problem of compatibility in the data. Our paper gives a solution to these issues by setting…

The value of B2B relationships
2009
PurposeThe purpose of the paper is to contribute to the knowledge of how relationship value, trust, commitment, satisfaction and loyalty intentions are defined and relate to each other. It explores these relationships in the business‐to‐business (B2B) context by analysing manufacturing companies regarding to their main supplier.Design/methodology/approachAfter the literature review and several in‐depth interviews, a method of empirical analysis consisting of quantitative intervention with an ad hoc survey using a structured questionnaire has been developed. Structural equations modeling is used to contrast the hypotheses on the links between the constructs analysed.FindingsConfirmatory fact…

Evaluating the motivating environment in Finland compared to the United States—a survey
1991
A comparison was made of perceptions of IS personnel—especially of analysts, programmers and managers—on factors relating to motivation and goal setting in Finland and the United States. The JDS/DP, a modification of the job diagnostic survey instrument, was used to collect data in these locations. The survey covered a statistically unbiased and representative sample in both countries. The results indicated significant similarities between the two populations. Not only were individual characteristics of growth-need and social-need similar, but their perception of job-related variables were also quite similar. The only differences found were in the job satisfaction of technical experts and i…
A survey on emotion detection: A lexicon based backtracking approach for detecting emotion from Bengali text
2017
Emotion recognition ability has been introduced as a core component of emotional competence. Every emotion has different ways to be expressed such as text, speech, lyrics etc. This paper reflects the current experimental study and their outcomes on emotion detection from different textual data. In case of lexicon-based analysis, the position of emotional lexicons really varies the state of an emotion. In this empirical study, our focus was to find how people use the emotional keywords to express their emotions. We have presented an emotion detection model to extract emotion from Bengali text at the sentence level. In order to detect emotion from Bengali text, we have considered two basic em…
