The reason behind this is efficient & effective working of aircraft. It also needs the high strength to weight ratio. This requirement is fulfilled by the composites. In this research, GLARE is a hybrid composite consisting of thin aluminum, glass fiber & epoxy layer. GLARE materials have been using over 36 years for wide range of advance aerospace structural applications. GLARE laminates offer a distinctive amalgamation of properties such as outstanding fatigue resistance, high specific static properties, exceptional impact resistance, good flame resistance, corrosion resistance and ease of manufacture and repair. But the delaminating occurs in the sheets of aluminum and similarly aluminum wire mesh is used. Solicitation of GLARE materials for the skin or the outer parts here presented the need of GLARE materials in supportive structural members; the present work focuses on the fabrication various structural cross sections of glare material. For fabrication purpose, selected method is hand lay-up. Static & dynamic analysis of these glare material cross sections was carried out; it follows a comparative study with the aluminum cross sections gives that the glare has a better performance.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125500987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the extensive literature review, the survey method was used to explore the relationships between the following variables: service quality, students' satisfaction, and word-of-mouth. The data were collected through an online self-administrated structured questionnaire administered to undergraduate and graduate STEM and IC students of the University of Rijeka Departments using Google Docs Forms. The findings provide some important insights into how the service quality impacts the students' satisfaction and word-of-mouth, in a Croatian higher education context. A high positive significant impact of service quality on students' satisfaction and word-of-mouth clearly indicates that it is an imperative for higher education sector. Based on the results and remarks of this study improvements can be planned and concluded across all dimensions. Policy makers in the industry in general and in the higher education sector, in particular, may benefit from the findings of this study.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126701032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One particularly promising area is the design of open source scientific hardware. Previous work has shown that the use of digital fabrication techniques has allowed scientists to make high-quality scientific tools for 1-10% of the cost of commercial proprietary equipment. Open source scientific hardware (and the open science movement in which it is situated) is part of a larger social shift characterised by open production methodologies, and decentralised and distributed models of collaboration. Design is also increasingly involved in supporting open production, both in terms of designing and developing technical infrastructures, and in terms of encouraging and sustaining processes that promote collaboration and openness. \u0000 \u0000This paper builds on the work of open source scientific hardware and emerging concepts in participatory design with a focus on commons-based peer production. How do open production environments foster engagement and innovation? Can distributed modes of production support the design of open source scientific hardware? To answer these questions, a design research case study was undertaken to investigate the design and social impact of a collaboratively designed open source hardware instrument developed by Sensorica, an open value network, in collaboration with an academic laboratory. The project’s goal was to engage with makers and communities around the world in order to encourage its wider adoption, future evolution and continued development.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115788143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has even been adopted by the World Economic Forum in 2011. Upstream is no stranger to Big Data. Understanding and leveraging data in the upstream segment enables firms to remain competitive throughout planning, exploration, delineation, and field development. Oil & Gas Companies conduct advanced geophysics modeling and simulation to support operations where Seismic generate significant data during exploration phases. They closely monitor the performance of their operational assets. To do this, they use thousands sensors in subsurface wells and surface facilities to provide continuous and real-time monitoring of assets and environmental conditions. Unfortunately, this information comes in various and complex forms, making it a challenge to collect, interpret, and leverage. Big Data technologies integrate common and disparate data sets to deliver the right information at the right time to the correct decision-maker. These capabilities help firms act on large volumes of data, optimizing all phases of exploration, development and production. Big Data ensure safer, more responsible operations. The aim of this paper is to explain how to use Big Data technologies to optimize operations. How can Big Data help experts to decision-making leading the desired outcomes?","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116740918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
