The increase of consumption is an important motivation for the reuse of either physical or virtual products. As the software market has risen, software reuse has become a practice with favourable effects for software development companies and their clients. The most important benefits are increased productivity, reduced costs, better and easier maintenance, decreased development lead times and the improved quality of software products. Successful reuse depends on several technical and non-technical factors. The ecological impact of software is an important non-technical factor of software reuse that needs to be analysed in the context of the rapid evolution of optimization techniques. The main goal of this study is to identify ecological perspectives on software reuse. These will complete the framework of software reuse together with other technical factors, such as compatibility, and non-technical factors, such as economic and ethical implications.
消费的增加是重复使用物理或虚拟产品的重要动机。随着软件市场的兴起,软件重用已经成为一种实践,对软件开发公司及其客户产生了有利的影响。最重要的好处是提高生产力、降低成本、更好更容易的维护、减少开发前置时间和提高软件产品的质量。成功的重用取决于几个技术和非技术因素。软件的生态影响是软件重用的一个重要的非技术因素,需要在优化技术快速发展的背景下进行分析。本研究的主要目的是确定软件重用的生态学观点。这些将与其他技术因素(如兼容性)和非技术因素(如经济和伦理影响)一起完成软件重用的框架。

Online social networks such as Facebook and LinkedIn create the opportunity to expand online and face-to-face ties. Diverse online social network composed by weak and strong ties is essential for the young student entrepreneurs. Online networks off diverse learning and online ex-pertize opportunities to the young student entrepreneur. This paper explores the entrepreneurial learning leverage that young students enrolled in higher education system can get from online ties in small economies through comparing Western Balkan region and more precisely a small developing country such as Albania with a small-developed county such as Estonia. The paper explores how online ties support young student readiness to use online networking platforms for online entrepreneurial learning and entrepreneurial opportunity recognition focusing in online ties established in Facebook and LinkedIn. Further online learning strategies are explored through focus group analysis, blog analysis and interviews with young experienced entrepreneurs. Young students use online ties for entrepreneurial knowledge sharing but there a difference between the Facebook tie and the LinkedIn tie. The study concludes with the suggestion of development of entrepreneurial learning orientation strategies and tools that facilitate the online learning process in both online networks focusing in specific online tie that is the group tie.
像Facebook和LinkedIn这样的在线社交网络创造了扩大在线和面对面联系的机会。由弱关系和强关系组成的多样化的在线社交网络对于年轻的学生创业者来说是必不可少的。在线网络为年轻的学生企业家提供了多样化的学习和在线专业机会。本文通过比较西巴尔干地区,更准确地说是阿尔巴尼亚等发展中小国与爱沙尼亚等小发达国家,探讨了小型经济体中高等教育系统中年轻学生可以从在线联系中获得的创业学习杠杆。本文探讨了在线联系如何支持年轻学生准备使用在线网络平台进行在线创业学习和创业机会识别,重点关注Facebook和LinkedIn建立的在线联系。通过焦点小组分析、博客分析和对有经验的年轻企业家的访谈,进一步探讨了在线学习策略。年轻的学生利用网络联系来分享创业知识,但Facebook的联系和LinkedIn的联系是有区别的。研究最后建议开发创业学习导向策略和工具,以促进在线网络中的在线学习过程,重点关注特定的在线关系,即群体关系。

The most enduring appeal of a mobile learning application is to enrich a curriculum regardless a specific domain of study. Mobile technology is a very versatile industry with quick connection to any untethered requirements coming from the realm of teaching activities. This article is dedicated to transfer a general understanding of concepts linked to a statistics course wrapped with a good knowledge and practice about programming languages used in mobile devices. For this objective we are starting a quest for finding relevant references through scientific articles regarding the main practically intertwined features between statistics, programming languages and teaching activities. We are trying to show that developing an Android mobile application is a practical solution that, in a simultaneously way, helps teachers to do a better teaching and evaluating activities and, besides that, speaking about students, we explain that reading, understanding and solving specific issues is a key target. We find that scientific community involved into m-learning subject is convinced that a higher exam scores is obtained, against traditional methods of doing lessons, when an evaluation regarding learning activity occurs. This paper contains the salient facts about creating an Android mobile application considering basic concepts taken from econometrics.
移动学习应用程序最持久的吸引力是丰富课程,而不是特定的学习领域。移动技术是一个非常通用的行业,可以快速连接到来自教学活动领域的任何不受限制的需求。本文致力于传递与统计课程相关的概念的一般理解,并包含有关移动设备中使用的编程语言的良好知识和实践。为了实现这一目标,我们开始通过科学文章寻找有关统计、编程语言和教学活动之间的主要实际交织特征的相关参考资料。我们试图展示开发Android移动应用程序是一个实用的解决方案,同时帮助教师更好地进行教学和评估活动,除此之外,谈到学生,我们解释了阅读,理解和解决具体问题是一个关键目标。我们发现,与传统的教学方法相比,参与移动学习主题的科学界相信,当对学习活动进行评估时,可以获得更高的考试分数。本文包含了关于创建Android移动应用程序的重要事实,考虑了计量经济学的基本概念。

Trading the financial markets is a wide activity nowadays. There are several indicators to measure this activity. The drawdown, the profit factor and the trading efficiency are some of them. This paper will present a different one: the quality trading coefficient. The new formula will indicate several particular aspects originating from the human psychological emotions and fears during transactions on the way to make profit. If the trade was fast and the price moved continuous to the profit target level, the quality trading coefficient will have a positive value close to one. When most of the time the trading position was on loss and the profit was made on the last part of the trade time, the coefficient will have a positive value more close to zero. If the trade is closed on losses, the coefficient will have a negative value tends to minus one if the market goes against the direction of the trade on the entire interval. Measuring this coefficient for all trades made with a trading strategy we can compare and categorize the strategies for any market and for any time interval. The quality trading coefficient became a new optimization criterion for the trading strategies used in automated trading systems.
如今,金融市场交易是一项广泛的活动。有几个指标可以衡量这种活动。其中包括回收量、利润系数和交易效率。本文将提出另一种方法:质量交易系数。新的公式将指出几个特定的方面,源于人类的心理情绪和恐惧,在交易过程中获利。如果交易速度快,价格连续移动到利润目标水平,质量交易系数将具有接近1的正值。当大部分时间交易头寸处于亏损状态,而在交易时间的最后一部分获利时,该系数将具有更接近于零的正值。如果交易因亏损而关闭,如果市场在整个区间内与交易方向相反,该系数将具有负值,趋于- 1。通过测量这个系数,我们可以对任何市场和任何时间间隔的交易策略进行比较和分类。交易质量系数成为自动化交易系统中交易策略优化的新准则。

Mihai Sandu, Ileana Simona Scarlat
Increasingly, interior design retailers rely on online stores to reach their customers as more and more people are connected to the internet. One of the issue in online shopping is that customers cannot visualize how new furniture pieces would blend in their home, but that is not the case anymore as Augmented Reality (AR) becomes more mainstream. This paper analyses several AR applications used in the interior design and highlights their pros and cons. Based on this analysis, we propose an AR application that solves most of the current issues of the interior spaces design.
随着越来越多的人连接到互联网,室内设计零售商越来越依赖在线商店来接触他们的客户。网上购物的一个问题是,顾客无法想象新家具如何融入他们的家,但随着增强现实(AR)变得越来越主流,这种情况已经不再存在了。本文分析了室内设计中使用的几种AR应用,并强调了它们的优缺点。在此基础上,我们提出了一种解决当前室内空间设计中大部分问题的AR应用。

The “buzz†surrounding cryptocurrencies in online media last year has led to an increased interest in the topic as a possible source for investments. This paper aims to identify the key success factors for an m-learning cryptocurrency application that explains blockchain technology and cryptocurrencies for non-tech savvy people. The research methodology used for this paper applies the experimental method and probative logic. A survey was conducted among 128 participants, the target population being composed of people who have an interest in cryptocurrencies and who are involved in online crypto communities. The results of the study show that the people who invest in cryptocurrencies are usually those who have a high income and who possess other investment methods as well. When it comes to analyzing the mobile applications success factors, the study revealed that there are no significant differences between people who have cryptocurrency investments and those who do not in ranking mobile apps success factors. Also, besides cryptocurrency training the news and prices are among the most important features of an m-learning cryptocurrency application and on that account such an app must include them. The originality of this study comes from addressing an innovative topic as the research in this field is scarce. Furthermore, this paper raises awareness towards the necessity of educating people on this topic, on the need to research before investing in a specific project.
去年围绕在线媒体中的加密货币的€œbuzzâ€导致人们对该主题的兴趣增加,将其作为可能的投资来源。本文旨在确定移动学习加密货币应用程序的关键成功因素,该应用程序为非技术娴熟的人解释了区块链技术和加密货币。本文的研究方法采用实验法和证明逻辑。在128名参与者中进行了一项调查,目标人群由对加密货币感兴趣的人和参与在线加密社区的人组成。研究结果表明,投资加密货币的人通常是那些收入高且拥有其他投资方法的人。在分析移动应用成功因素时,该研究显示,在对移动应用成功因素进行排名时,投资加密货币的人和没有投资加密货币的人之间没有显著差异。此外,除了加密货币培训之外,新闻和价格也是移动学习加密货币应用程序最重要的功能之一,因此此类应用程序必须包含它们。本研究的独创性来自于在该领域的研究较少的情况下解决了一个创新的主题。此外,本文还提高了人们对这一主题的教育必要性的认识,以及在投资特定项目之前进行研究的必要性。

The work reported in the paper focuses on the prediction of the exchange rate of the Swiss Franc-Romanian Leu against the US Dollar-Romanian Leu using the NARX model. We propose two new forecasting methods based on NARX model by considering both additional testing and network retraining in order to improve the generalization capacities of the trained neural network. The forecasting accuracy of the two methods is evaluated in terms of one of the most popular quality measure, namely weighted RMSE error. The comparative analysis together with experimental results and conclusive remarks are reported in the final part of the paper. The performances of the proposed methodologies are evaluated by a long series of tests, the results being very encouraging as compared to similar developments. Based on the conducted experiments, we conclude that both resulted algorithms perform better than the classical one. Moreover, the retraining method in which the network is conserved over time outperforms the one in which only additional testing is used.
本文报告的工作重点是使用NARX模型预测瑞士法郎-罗马尼亚列伊对美元-罗马尼亚列伊的汇率。为了提高训练后神经网络的泛化能力,我们提出了两种新的基于NARX模型的预测方法,同时考虑了附加测试和网络再训练。两种方法的预测精度是根据一个最流行的质量指标,即加权均方根误差进行评估。论文的最后部分给出了对比分析、实验结果和结论性意见。拟议的方法的性能通过一系列测试进行了评估,与类似的发展相比,结果非常令人鼓舞。实验结果表明,两种算法的性能都优于经典算法。此外,随着时间的推移,网络保持保守的再训练方法优于只使用额外测试的方法。

Moreover, the retraining method in which the network is conserved over time outperforms the one in which only additional testing is used.","PeriodicalId":53248,"journal":{"name":"Informatica economica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74578912","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}

This paper presents the current state of AR technology applications in the field of construction through some examples already applied in simulation of the organization of utilities networks, simulation of site organization in various stages, simulation of the new urban plan, modeling of building details, interior organization and navigation site and proposes to design of an IT application that integrates these benefits into a unitary application, easy to use by all parties involved in project: project owner, architects, builders, local community and public authorities. The application will be specific to the Android platform and will provide a virtual view of the stages in the construction. It will also run on mobile devices such as smartphones, tablets, or other devices that have a camera, internet connection, and location sensors.
本文通过一些实例介绍了AR技术在建筑领域的应用现状,这些实例已经应用于模拟公用事业网络组织、模拟各个阶段的现场组织、模拟新的城市规划、建筑细节建模、室内组织和导航站点,并提出设计一个IT应用程序,将这些优点集成到一个统一的应用程序中,便于项目各方使用:项目业主、建筑师、建筑商、当地社区和公共当局。该应用程序将专门针对Android平台,并将提供构建阶段的虚拟视图。它还将在智能手机、平板电脑或其他带有摄像头、互联网连接和位置传感器的移动设备上运行。
