Modularisering og koordinering mellom flere aktører i et innovasjonsprosjekt : modulbaserte marine løsninger for aktivitetsanlegg og gjestehavner

2014

Masteroppgave i industriell økonomi og teknologiledelse IND 590 Universitetet i Agder 2014 Prosjektet vi har tatt for oss skal i første rekke utvikle fysiske løsninger, prinsipper og produksjonsprosesser som raskt kan oversette kundekrav, arealmessige og naturgitte forutsetninger til bryggeløsninger og anlegg av høy kvalitet. Anlegg og løsninger skal være skalerbare slik at man i tillegg til store gjestebrygger/anlegg, som skal utvikles i samarbeid med Arendal Havn i dette OFU-prosjektet, også kan adressere for eksempel små private bryggeanlegg som marked. Fleksibiliteten og kundetilpasning muliggjøres ved en gjennomgående modularisering- og plattformtankegang. Prosjektet er sammensatt av i…

Experimental Study of Vibrations in Face Milling Cutting

2014

Abstract The present paper consists in a comparison of vibrations measured during face milling cutting with two constructive variants of milling cutters (one with classic insert clamping and other with a quick insert adjustment mechanism). The goal of the study is to determine if the new clamping mechanism of the inserts has a similar behaviour with the classic one and can withstand milling conditions without introducing additional vibrations in the system

Web Monitoring System and Gateway for Serial Communication PLC

2012

Abstract An industrial process requires interacting with the rest of the plant, being able to exchange data with other devices and monitoring systems in order to optimize production, reporting information and providing control capabilities to distant users. Internet, and, especially web browsers are an excellent tool to provide information for remote users, allowing not only monitoring but also controlling the industrial process as an SCADA software or HMI system. The proposed system does not need specific proprietary software and its associated license costs. In this work, a webserver system is implemented under a Freescale microcontroller, acting as a gateway for a simple PLC with single …

Implications of the Modular Curriculum in the Senior Secondary School in Finland

2004

Interest in the modular curriculum has increased during the last few years. The modular approach has been seen as a promising curriculum model when more flexible structures are sought for reorganizing education. It creates alternatives for organizing school work in a pedagogically functional way in which individual students are offered more opportunities to select their own program of study (Warwick, 1988). Co-operation with schools has increased and forced schools to find common principles to arrange the timetables and daily schoolwork. In this context, the modular curriculum provides an instrument to outline the purpose and goals of schoolwork in a new way, and put them into practice at t…

An Image Segmentation Algorithm based on Community Detection

2016

International audience; With the recent advances in complex networks, image segmentation becomes one of the most appropriate application areas. In this context, we propose in this paper a new perspective of image segmentation by applying two efficient community detection algorithms. By considering regions as communities, these methods can give an over-segmented image that has many small regions. So, the proposed algorithms are improved to automatically merge those neighboring regions agglomerative to achieve the highest modularity/stability. To produce sizable regions and detect homogeneous communities, we use the combination of a feature based on the Histogram of Oriented Gradients of the …

Modular Assembly of Multimodal Imaging Agents through an Inverse Electron Demand Diels–Alder Reaction

2019

International audience; The combination of two imaging probes on a same biomolecule gives access to targeted bimodal imaging agents that can provide more accurate diagnosis, complementary information, or that may be used in different applications, such as PET imaging and fluorescence imagingassisted surgery. In this study, we demonstrate that dichlorotetrazine, a small, commercially available compound, can be used as a modular platform to easily assemble various imaging probes. Doubly-labeled tetrazines can then be conjugated to a protein through a biorthogonal IEDDA reaction. A series of difunctionalized tetrazine compounds containing various chelating agents and fluorescent dyes was synth…

Novel Three-Phase Multilevel Inverter With Reduced Components for Low- and High-Voltage Applications

2021

In this article, a novel multilevel topology for three-phase applications, having three-level and hybrid N -level modular configurations, enabling low-, medium-, and high-voltage operations, is presented. The proposed topology has several attractive features, namely reduced component count, being capacitor-, inductor-, and diode-free, lowering cost, control-complexity, and size, and can operate in a wide range of voltages and powers. Selected simulation and experimental results are presented to verify the performance of the proposed topology. Further, the overall efficiency of the topology and loss distribution in switches are studied. Finally, the key features of the proposed topology in t…

Ontological Analysis and Modularization of CIDOC-CRM

2020

Conference cancelled due to COVID19; International audience; The CIDOC-CRM ontology is a standard for cultural heritage data modeling. Despite its large exploitation, the ontology is primarily maintained in a semi-formal notation, which makes it difficult to homogeneously exploit it in digital environments. In addition, the ontology consists of several classes and relations, whereas one sometimes wishes to reuse it but only partially. The purpose of the paper is to contribute to the use of CIDOC by strengthening its foundations. On the basis of formal ontology theories, we propose a first analysis of the ontology to enhance its conceptual structure. We also present a preliminary modularizat…

The Aquatic Surface Robot (AnSweR), a Lightweight, Low Cost, Multipurpose Unmanned Research Vessel

2021

Even though a few examples of aquatic surface robots exist, they are generally expensive, relatively large and heavy and tailored to custom-made hardware/software components that are not openly available to a broad public. In this work, the Aquatic Surface Robot (AnSweR), a newly-designed, lightweight, low cost, open-source, multipurpose unmanned research vessel is presented. The AnSweR features a lightweight and compact design that makes it fit in a backpack. Low-noise operation (in and above the surface) is achieved with a propulsion system based on two water-jets. Only affordable commercial-off-the-shelf (COTS) components are adopted. The primary goal of the AnSweR is to map underwater l…
