Automatic Identification

In this lesson you will learn about text reuse detection -- the automatic identification of reused passages in texts -- and why you might want to use it in your research. Through a detailed installation guide and two case studies, this lesson will teach you the ropes of Passim, an open source and scalable tool for text reuse detection.

Purpose Isolated communities face a variety of inconveniences including severe remoteness, poor roads and extreme climate conditions, resulting in the lack of security of supply chains and exorbitant prices for cargo delivery. This paper aims to investigate the present advantages and prospects of applying 3-D printing to improve economics and everyday life of remote communities, reindeer herder case taken as an example. Design/methodology/approach This study covers the use of a low-cost open-source 3-D printer (RepRap) capable of fused filament fabrication to reduce operating costs for nomadic reindeer herder groups. Three case studies are provided for reindeer-specific applications to probe economic and technical viability of the technology, namely, ear-tags, electric fence components and lasso accessories. Findings 3-D printed objects feature technical characteristics similar to those of analogues available on the market while reducing the price by 63 per cent. Distributed 3-D printing reduces the cost of raw materials by 68 per cent and shipping costs by 50 because of lower trip frequency. If all reindeer herders globally were to adopt distributed manufacturing of the three aforementioned sample items only, their annual savings from such solution would amount to US$2m. The paper discovers other economic, entrepreneurial, technical and environmental opportunities offered by 3-D printing put to service the needs of remote communities. Research limitations As the paper is the first-ever study of 3-D printing potential applied to the reindeer husbandry case, it is based on a more thorough analysis of the techno-economic feasibility of the technology, while cultural and entrepreneurial factors have been discussed as preconditions only. Practical implications The paper might serve as a valuable source of information for entrepreneurs, as well as for students and academics for further case studies in this area. Originality/value In remote conditions, 3-D printing offers a more sustainable way of good manufacturing. Numerous open source designs already available for specialists, financial effectiveness, environmental benefits and vast opportunities for entrepreneurs are among the most promising advantages of the technology.

The Web Service Offerings Infrastructure (WSOI) is a monitoring and management infrastructure for the Web Service Offerings Language (WSOL). It extends Apache Axis, an open-source tool for hosting Web services. We present technical details of several WSOI solutions for monitoring Web Services. To pass management information among management parties, we built WSOI serializer and WSOI deserializer modules converting data between formats of Axis’ MessageContext properties and SOAP headers. To perform different monitoring activities for different WSOL service offerings, we implemented Web Service Offering Descriptor (WSOD) as a complement to Axis’ Web Service Deployment Descriptor (WSDD) component. To represent run-time values of WSOL-related management information, we developed WSOI management information model. All these solutions were verified with a prototype implementation of WSOI 2.0 and validated on case studies.

Permission-related issues in Android apps have been widely studied in our research community, while most of the previous studies considered these issues from the perspective of app users. In this paper, we take a different angle to revisit the permission-related issues from the perspective of app developers. First, we perform an empirical study on investigating how we can help developers make better decisions on permission uses during app development. With detailed experimental results, we show that many permission-related issues can be identified and fixed during the application development phase. In order to help developers to identify and fix these issues, we develop PerHelper, an IDEplugin to automatically infer candidate permission sets, which help guide developers to set permissions more effectively and accurately. We integrate permission-related bug detection into PerHelper and demonstrate its applicability and flexibility through case studies on a set of open-source Android apps.

AbstractVirtual Reconstruction is a powerful tool broadly suited to a diverse array of archaeological heritage applications. In practice, however, reconstruction has largely focused on grand and monumental sites. Here we present two case studies–one from southern Oklahoma, the other from western Nebraska–to explore the use of this technology for more common heritage applications. The goal of this article is to advertise the dilemma we faced with communicating information on ephemeral sites and how we, as nonspecialists, solved the issue using affordable and accessible digital tools. Our workflow makes use of common tools (GIS) and open source software and online tutorials provide step by step instruction to support its replication. In presenting our experiences and the results of these efforts, we hope to spur similar applications in the use of Virtual Reconstruction to communicate information on archaeological heritage more broadly.

Marine Navigation

One of the most controversial issues relating to marine navigation is the efficacy of ships' crews using VHF radio technology for bridge-to-bridge communications to agree manoeuvres. Through a re-evaluation of historic case studies, this paper provides background on the development of applying VHF technology in collision avoidance and the legislation, national and international, underpinning the practice; a practice that has found little or no support from the legal establishment. Finally the consequential development of a policy to require specific VHF technology to be installed on ships to facilitate agreements in relation to collision avoidance manoeuvres will be reviewed, that is the Automatic Identification System (AIS).Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.
