Are software start-ups different? An empirical study on performance of Finnish software companies 软件创业公司不同吗?芬兰软件公司绩效实证研究
A. Suominen, S. Hyrynsalmi, Leena Aarikka-Stenroos, M. Seppänen
Entrepreneurship and start-ups have become modern hype terms. Especially, software start-ups have gathered a lot of interest due to a few successful examples, and the potential scalability of new business. A plethora of accelerators, events and communities has been found as well as new research agendas announced to boost and study the new phenomenon. The question, are software start-ups different, still remains unanswered. This study address whether software start-ups differ from the other kinds of new companies. We use the set of over 20,000 Finnish companies founded during 2010–2013 as an empirical material for our inquiry. To compare the financial performance of software start-ups and the rest, we use the current ratio, profit margin, revenue and return on assets as measures of financial performance. The results show that, indeed, software start-ups differ from the control group in the used financial indicators.
创业和初创企业已经成为现代的炒作术语。特别是,由于一些成功的例子,以及新业务的潜在可扩展性,软件初创企业吸引了很多人的兴趣。人们发现了大量的加速器、活动和社区,并宣布了新的研究议程来促进和研究这一新现象。软件初创企业是否与众不同,这个问题仍然没有答案。本研究探讨了软件初创企业是否与其他类型的新公司不同。我们使用2010-2013年期间成立的超过20,000家芬兰公司作为我们调查的实证材料。为了比较软件初创公司和其他公司的财务表现,我们使用流动比率、利润率、收入和资产回报率作为财务表现的衡量标准。结果表明,软件初创企业在使用的财务指标上确实与对照组有所不同。

A heuristic approach for early-stage product development in extreme environments 极端环境下早期产品开发的启发式方法
Jardar Winjum, A. Wulvik, Jorgen A. B. Erichsen, T. Welo, M. Steinert
This article considers a heuristic approach for developing products for extreme environments. The authors propose a set of heuristics for exploring environment and product features throughout the design probing process. The proposed strategy is exemplified through several cases, with special emphasis placed on a project that considers developing new products for aluminium electrolysis shop floor environments. These heuristics are presented as an approach for dealing with large amounts of uncertainty in an early-stage product development setting.

User satisfaction evaluation of Malaysian e-government education services 马来西亚电子政务教育服务的用户满意度评价
M. Wong, Stephen Jackson
This paper investigates user satisfaction evaluation of Malaysian e-government education services. Although different frameworks and methods have been used to evaluate the quality of online services e.g., SERVQUAL, SERVPERF and other practitioner-orientated tools, in this paper we propose the usefulness of importance-performance analysis (IPA). A major benefit of IPA is that it allows both importance and performance to be measured using a two-dimensional grid. More specifically, IPA is used to evaluate education online services in Malaysia from the user (citizen) perspective and to identify areas of strategic importance which can help to improve future online services in Malaysia. The paper raises the issue that despite the increased uptake of e-government in Malaysia, there is the need for more practical evaluation tools to gauge the perceptions of citizens in their use of e-government, particularly from an educational context.
本文调查了马来西亚电子政务教育服务的用户满意度评价。尽管已经使用了不同的框架和方法来评估在线服务的质量,例如SERVQUAL、SERVPERF和其他面向从业者的工具,但在本文中,我们提出了重要性-绩效分析(IPA)的有用性。IPA的一个主要优点是它允许使用二维网格来测量重要性和性能。更具体地说,IPA用于从用户(公民)的角度评估马来西亚的在线教育服务,并确定有助于改善马来西亚未来在线服务的战略重要性领域。这篇论文提出了一个问题,即尽管马来西亚越来越多地采用电子政务,但仍需要更实用的评估工具来衡量公民对电子政务使用的看法,特别是从教育方面。

TAF agile framework reducing uncertainty within minimum time and resources TAF敏捷框架在最短的时间和资源内减少了不确定性
Rafael Hostettler, A. I. Bohmer, U. Lindemann, A. Knoll
TAF Agile Framework addresses the challenge of providing a methods framework for agile mechatronic product development. It aims to reduce uncertainty towards the product within minimum time and resources by taking a holistic, interdisciplinary perspective on the product and iteratively increases knowledge by applying the scientific method to the domains of desirability, feasibility and viability. It crystallizes this knowledge by building prototypes and artifacts to disseminate it quickly throughout large teams. It integrates best practices from traditional mechatronic development (e.g. Munich Procedural Model) with methods inspired by lean startup, scrum and design thinking. It coordinates cross-functional teams and helps to identify critical functions in order to build the right things before building them right. TAF is applied wherever companies need to adapt to a changing market, where the current business model or rather product lost its viability and where mechatronic products are developed de-novo. In this study, TAF Agile Framework is deduced from the combined experience of 37 agile mechatronic development projects and evaluated with the results of 13 further projects during a two weeks lab course at TU Munich.
TAF敏捷框架解决了为敏捷机电产品开发提供方法框架的挑战。它的目的是在最短的时间和资源内减少对产品的不确定性,通过对产品采取整体的、跨学科的观点,并通过将科学方法应用于可取性、可行性和可行性领域来迭代地增加知识。它通过构建原型和工件来将这些知识结晶,以便在大型团队中快速传播。它将传统机电一体化开发的最佳实践(例如慕尼黑过程模型)与受精益创业、scrum和设计思维启发的方法相结合。它协调跨职能团队,并帮助确定关键功能,以便在正确构建之前构建正确的东西。只要公司需要适应不断变化的市场,当前的商业模式或产品失去了生存能力,或者机电产品需要从头开发,就可以应用TAF。在本研究中,TAF敏捷框架是从37个敏捷机电一体化开发项目的综合经验中推导出来的,并与慕尼黑工业大学两周实验课程中13个进一步项目的结果进行了评估。

PREMIuM: Big data platform for enabling self-healing manufacturing 优势:实现自修复制造的大数据平台
Ljiljana Stojanović, N. Stojanović
The role of big data analytics in modern manufacturing has been proven, esp. in the area of improving process efficiency. This paper goes a step forward and introduces requirements/challenges for enabling a continuous process improvement. It means that a manufacturing system will be able not only to react on a problem at hand, but rather to sense the problem (in advance) and proactively resolve the situation. In this paper, we focus on a specific type of self-adaptive manufacturing systems, which are able to resolve the problems with the equipment in an autonomous way (the so-called self-healing). The paper describes the detailed design of the platform called PREMIuM for realizing self-healing manufacturing. The platform is based on our existing work related to the big data analytics, in particular D2Lab framework for developing industry data analytics solutions. We provide also some insights from an initial validation study.
大数据分析在现代制造业中的作用已经得到证实,特别是在提高流程效率方面。本文向前迈进了一步,并介绍了实现持续过程改进的需求/挑战。这意味着制造系统不仅能够对手头的问题做出反应,而且能够(提前)感知问题并主动解决问题。在本文中,我们关注的是一种特殊类型的自适应制造系统,它能够以自主的方式解决设备的问题(所谓的自修复)。本文介绍了实现自修复制造的PREMIuM平台的详细设计。该平台基于我们现有的与大数据分析相关的工作,特别是用于开发行业数据分析解决方案的D2Lab框架。我们还提供了一些来自初步验证研究的见解。

The concept of a need-driven ecosystem and its application to mobility 需求驱动型生态系统的概念及其在移动出行中的应用
Henning Hinderer, Ludwig Martin
Individual mobility has been a vital need of human beings ever since. Countless innovations have increased the naturally given possibilities to move from one location to another. These typically being as fast, safe and comfortable as possible. Equipment such as horse-drawn carriages, bicycles, cars or airplanes have been invented and continuously developed over centuries. Besides that services for orientation, navigation, planning or insuring as well as devices for entertainment and communication have been added. Various sources of energy are powering this mobility. The band starts from the brawn of animals continued to the chemically stored energy in crude oil and further to an increased use of electrical energy gained from renewable sources. In order to provide and satisfy the need for modern mobility various products, parts, devices and data are necessary as well numerous players and stakeholders are involved. In the past major changes and innovations had been pushed by the providers of the equipment such as car manufacturers. However, at present and even more in the future it appears like prerequisites for such change have altered significantly due to the increased complexity of the context. The next major steps might be driven by integration of products and needs as well as the best access of services for the individual aiming for mobility. To understand the overarching interdependencies and impacts of all relevant products, services and players this paper proposes the metaphor of a Need-driven Ecosystem. In such ecosystem interdependencies, the continued development, resource competition, technical innovation and its impact on societies and individuals can be depicted, and better understood by role-players. Such approach will assist researchers in detecting interdependencies and impacts of their work better. An application to understand the complexities of individual mobility in a Mobility Ecosystem are shown.
从那时起,个人的流动性就一直是人类的重要需求。无数的创新增加了从一个地方到另一个地方的自然可能性。它们通常是尽可能快速、安全和舒适的。马车、自行车、汽车或飞机等设备已经被发明并不断发展了几个世纪。此外,还增加了定位、导航、规划或保险服务以及娱乐和通信设备。各种各样的能源为这种移动性提供动力。从动物的肌肉开始,继续到原油中化学储存的能量,再到从可再生能源中获得的电能的增加使用。为了提供和满足现代移动出行的需求,各种产品、零件、设备和数据都是必要的,而且涉及许多参与者和利益相关者。在过去,主要的变革和创新是由汽车制造商等设备供应商推动的。然而,在目前,甚至在未来,由于环境的复杂性增加,这种变化的先决条件似乎已经发生了重大变化。接下来的主要步骤可能是由产品和需求的集成以及为个人提供最佳的移动性服务来推动的。为了理解所有相关产品、服务和参与者的总体相互依赖性和影响,本文提出了需求驱动生态系统的比喻。在这种生态系统的相互依赖中,角色扮演者可以描述和更好地理解持续发展、资源竞争、技术创新及其对社会和个人的影响。这种方法将有助于研究人员更好地发现其工作的相互依赖性和影响。展示了一个应用程序,用于理解移动生态系统中个人移动的复杂性。

A low power smart camera for video surveillance and forensic applications 用于视频监控和法医应用的低功耗智能摄像头
M. Lecca, Yu Zou, M. Gottardi
We describe a custom, low-power surveillance camera for the control of isolated, peripheral areas, that are often chosen for illegal activities, like traffic of drugs, weapons and cigarettes. The camera embeds on chip an image processing algorithm for real-time event detection, exploiting a dynamic background subtraction approach to identify the so-called hot-pixels, i.e. pixels undergone an intensity variation, and possibly corresponding to an abnormal action. Every time a group of hot-pixels is detected, the camera generates an alarm that can be sent to an external processor for further processing (e.g. scene classification) or to a surveillance officer to plan an intervention. The related frames are saved to be used as forensic evidence in a court. The presented vision sensor combines the image array with a bench of processors, frame buffer, timing control block and digital interface. Low-power performance is obtained through custom chip design techniques, combined with integrated image processing and different sensor operating modes to minimize the sensor average power consumption. The vision sensor performance has been evaluated by two European LEAs, which expressed a high level of interest in such a system and a positive vote about its event detection performance.
我们描述了一种定制的低功率监控摄像头,用于控制孤立的外围区域,这些区域经常被用于非法活动,如毒品、武器和香烟的贩运。摄像机在芯片上嵌入了一种实时事件检测的图像处理算法,利用动态背景减法来识别所谓的热像素,即像素经历了强度变化,并且可能对应于异常动作。每当检测到一组热像素时,摄像机就会产生一个警报,该警报可以发送到外部处理器进行进一步处理(例如场景分类)或发送给监控人员以计划干预。相关的画面被保存下来作为法庭上的法医证据。该视觉传感器将图像阵列与处理器、帧缓冲区、时序控制块和数字接口相结合。通过定制芯片设计技术,结合集成图像处理和不同的传感器工作模式,获得低功耗性能,最大限度地降低传感器的平均功耗。视觉传感器的性能已经由两个欧洲LEAs进行了评估,他们对这种系统表达了高度的兴趣,并对其事件检测性能进行了积极的投票。

Gottardi","doi":"10.1109/ICE.2017.8279943","DOIUrl":"https://doi.org/10.1109/ICE.2017.8279943","url":null,"abstract":"We describe a custom, low-power surveillance camera for the control of isolated, peripheral areas, that are often chosen for illegal activities, like traffic of drugs, weapons and cigarettes. The camera embeds on chip an image processing algorithm for real-time event detection, exploiting a dynamic background subtraction approach to identify the so-called hot-pixels, i.e. pixels undergone an intensity variation, and possibly corresponding to an abnormal action. Every time a group of hot-pixels is detected, the camera generates an alarm that can be sent to an external processor for further processing (e.g. scene classification) or to a surveillance officer to plan an intervention. The related frames are saved to be used as forensic evidence in a court. The presented vision sensor combines the image array with a bench of processors, frame buffer, timing control block and digital interface. Low-power performance is obtained through custom chip design techniques, combined with integrated image processing and different sensor operating modes to minimize the sensor average power consumption. The vision sensor performance has been evaluated by two European LEAs, which expressed a high level of interest in such a system and a positive vote about its event detection performance.","PeriodicalId":421648,"journal":{"name":"2017 International Conference on Engineering, Technology and Innovation (ICE/ITMC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127399875","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}
