App Development

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.

Rapid Changes

There is an increasing need for organizations to adapt to rapid changes in society. This need requires organizations’ and the leader within them, to explore, recognize, build and exploit new capabilities. Researching such capabilities has drawn attention from the design management research community in recent years. Dominantly, research contributions have focused on perspectives of innovation and the strategic application of design with the researcher distanced from context. Descriptive and evaluative case studies of past organizational leadership have been vital, by building momentum for the design movement. However, there is a need now to progress toward prescriptive and explorative research perspectives that embrace context through practice and the simultaneous research of design.  Therefore, the aim of this track is to lead and progress discussion on research methodologies that support the research community in developing explorative and prescriptive research methodologies for context-orientated organizational research. This track brings together a group of diverse international researchers and practitioners to fuel discussion on design approaches and subsequent outcomes of prescriptive and explorative research methodologies.

AbstractCar crash simulation analysis is an important phase within the vehicle development. It intends to analyse the crashworthiness of the vehicle model and examine the level of passive security. However, this activity is not trivial because of the considerable collaboration within the project, the large amount of analysed and exchanged data and a high exigency. Consequently, a solution to assist, ease and reduce the time of the process is desired.To study the current practices followed in the car crash simulation analysis an empirical study has been conducted. This study has been applied within the simulation analysis team, in the development phase, within an automotive company. This paper describes a qualitative analysis of the industrial context and diagnoses the dysfunctions in the current practices. This paper also highlights the current challenges encountered in the car crash simulation analysis.

The growing application of smart manufacturing systems and the expansion of the Industry 4.0 model have created a need for new teaching platforms for education, rapid application development, and testing. This research addresses this need with a proposal for a model of working environment monitoring in smart manufacturing, based on emerging wireless sensor technologies and the message queuing telemetry transport (MQTT) protocol. In accordance with the proposed model, a testing platform was developed. The testing platform was built on open-source hardware and software components. The testing platform was used for the validation of the model within the presented experimental environment. The results showed that the proposed model could be developed by mainly using open-source components, which can then be used to simulate different scenarios, applications, and target systems. Furthermore, the presented stable and functional platform proved to be applicable in the process of rapid prototyping, and software development for the targeted systems, as well as for student teaching as part of the engineering education process.

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.
