Using advanced FPGA SoC technologies for the design of industrial control applications 采用先进的FPGA SoC技术设计工业控制应用
C. Economakos, G. Kiokes, G. Economakos
Modern industrial control systems must offer performance, flexibility and reliability. On the same time, they need to reach the market as early as possible and at low cost. Finally, they need to operate as embedded devices with low power budget. On top of that, the algorithms that they implement are getting even more sophisticated, advanced and demanding. To cope with all these diverse requirements, control system designers are moving with fast steps to the digital hardware design field and specifically, FPGAs, System-on-Chip architectures and productivity improving methodologies like High-Level Synthesis, which uses C/C++ as an abstract hardware description language. In this paper, using these tools, the implementation of 3 control algorithms is shown, the classical PID algorithm, a Fuzzy Logic Controller (FLC) and an Adaptive or Tuning Fuzzy Logic Controller (TFLC). The novelty of the proposed approach is that through specific coding and compiler directives, the C/C++ input descriptions are automatically implemented as advanced multicore architectures (3 most advanced of them are put to extensive experimentation and compared), which execute up to 500K algorithm iterations in less that 1 sec, taking advantage of an embedded ARM family microcontroller and common memory blocks found in the underlying FPGA implementation device. This is a substantial performance improvements and a high productivity boost, with very promising future extension capabilities.
现代工业控制系统必须提供高性能、灵活性和可靠性。与此同时,他们需要以较低的成本尽早进入市场。最后,它们需要作为低功耗预算的嵌入式设备运行。最重要的是,它们实现的算法变得更加复杂、先进和苛刻。为了应对所有这些不同的需求,控制系统设计人员正在快速转向数字硬件设计领域,特别是fpga,片上系统架构和生产力提高方法,如使用C/ c++作为抽象硬件描述语言的高级综合。在本文中,使用这些工具,展示了3种控制算法的实现,即经典PID算法,模糊逻辑控制器(FLC)和自适应或调谐模糊逻辑控制器(TFLC)。所提出的方法的新颖之处在于,通过特定的编码和编译器指令,C/ c++输入描述自动实现为先进的多核架构(其中最先进的3个进行了广泛的实验和比较),利用底层FPGA实现设备中的嵌入式ARM家族微控制器和公共内存块,在不到1秒的时间内执行高达500K的算法迭代。这是一个实质性的性能改进和高生产力提升,具有非常有前途的未来扩展功能。

Hybrid-based optimization of wireless channel characterization for health services in medical complex environments 基于混合的医疗复杂环境中健康服务无线信道特性优化
Fran Casino, L. Azpilicueta, P. López-Iturri, E. Aguirre, F. Falcone, A. Solanas
Nowadays, plenty of simulation techniques based on deterministic methods like Ray Tracing and Ray Launching, combining Geometric Optics and Uniform Theory of Diffraction, are used to predict waves' behaviour within a defined environment and to make better decisions on the deployment of antennas for particular purposes. However, simulations' quality largely depends on the number of rays, providing sufficient angular resolution in the ray launching process. The computational cost of simulations in high definition (HD) prevents their use in complex environments and their low definition (LD) counterparts are used. In this article we propose a technique based on collaborative filtering (CF) to lessen the low quality problems of LD simulations. Such technique outperforms previous works in this field in terms of accuracy, precision and computational cost. Moreover, we show that our approach obtains results very similar to those of HD in much less time. Therefore, using combined deterministic-CF techniques allows the estimation of radio-planning tasks in large, complex medical scenarios with a potentially large amount of transceivers.
如今,许多基于确定性方法的模拟技术,如射线追踪和射线发射,结合几何光学和均匀衍射理论,被用来预测波在特定环境中的行为,并为特定目的做出更好的天线部署决策。然而,模拟的质量很大程度上取决于光线的数量,在光线发射过程中提供足够的角分辨率。高清晰度(HD)模拟的计算成本阻碍了它们在复杂环境中的应用,而低清晰度(LD)模拟则被使用。在本文中,我们提出了一种基于协同滤波(CF)的技术来减少LD仿真的低质量问题。该技术在精度、精密度和计算成本方面都优于该领域的前人研究成果。此外,我们表明,我们的方法在更短的时间内获得了与HD非常相似的结果。因此,使用组合确定性- cf技术可以在具有潜在大量收发器的大型复杂医疗场景中估计无线电规划任务。

O. Kalita, Tatiana Balykxina, G. Pavlidis
As much as mobile technology is enhanced and, more particularly, as much as the speed in which smart mobile devices introduced into the people's everyday lives, increases the possibilities of the usage of this technology in distance learning. New applications should definitely keep a thin balance among these technological possibilities, the widely used distance learning platforms and the pedagogical subsistence of the educational procedure. Furthermore, they must (i) support the position and make teacher's work easier, as a leader of the educational process, (ii) take into account the knowledge and creativity of the students, (iii) make a better adaptation of the educational material to the needs, goals, special interests etc. of the students. In this work, an innovative application of mobile technology in learning a foreign language - at this case Russian verbs of motion by Greek students - is presented.
随着移动技术的发展,尤其是智能移动设备进入人们日常生活的速度越来越快,在远程学习中使用这种技术的可能性也越来越大。新的应用程序应该在这些技术可能性、广泛使用的远程学习平台和教育过程的教学生存之间保持一种微妙的平衡。此外,它们必须(1)支持教师作为教育过程领导者的地位,使教师的工作更容易;(2)考虑到学生的知识和创造力;(3)使教材更好地适应学生的需要、目标、特殊兴趣等。在这项工作中,移动技术在学习外语中的创新应用-在这种情况下,希腊学生的俄语动作动词-被提出。

Crysanthi Tseloudi, T. Tsiatsos
With the evolution of technology, social media and mobile devices, digital games have become a frequent form of entertainment for many people. As games can provide a fun environment, where students can actively learn content through actions and decisions, there are high hopes that game-based learning can be used both in and outside the classroom and yield positive learning outcomes. The aim of this study is to evaluate the effectiveness and enjoyment of a game created for art history learning, on adults of various ages, with a different art history background and game experience and to hopefully help educational game creators get closer to a balance between fun and learning.

Coalescing terrestrial laser scanning and aerial orthophotography for urban 3D modelling 结合地面激光扫描和航空正射影摄影的城市三维建模
A. Konstantaras, J. Kilty, E. Maravelakis
Recent advances in aerial photography enabled cadastrates of several countries to proceed to the cartography of rural areas and record existing forestry, farming yards, plane fields and registered land ownerships. Efforts are being made to expand this project to urban areas as well, where the main object of interest apart from land itself are the buildings themselves. The main difficulty with buildings is that they are 3D objects and additional to their planar expansion there is also their height that is of significance as well. This paper aims to comprise planar information obtained through features' extraction from ortho-open aerophotographs with vertical information obtained using terrestrial laser scanning to produce three dimensional models of multiple neighboring building blocks in an urban area. Results from the application of the proposed approach to the historic 1866 square in Chania, Greece, demonstrate both the capabilities and difficulties associated with such an attempt and derive useful conclusions for future advancements that can lead to valuable topographical urban three dimensional mappings.
航空摄影技术的最新进展使若干国家的地籍地能够着手绘制农村地区的地图,并记录现有的森林、农场、飞机场和已登记的土地所有权。正在努力将该项目扩展到城市地区,在城市地区,除了土地本身之外,主要的兴趣对象是建筑物本身。建筑的主要困难在于它们是3D对象,除了它们的平面扩展外,它们的高度也很重要。本文旨在将正交开放航拍影像特征提取得到的平面信息与地面激光扫描得到的垂直信息相结合,生成城市区域内多个相邻建筑块的三维模型。将该方法应用于希腊哈尼亚历史悠久的1866年广场的结果,展示了这种尝试的能力和困难,并为未来的进步得出有用的结论,这些结论可以导致有价值的城市地形三维映射。

Introducing sailboats into ship routing system VISIR 将帆船引入船舶路由系统VISIR
G. Mannarini, R. Lecci, G. Coppini
A prototype of sailboat routing system for least-time navigation is presented. The routing algorithm is based on an exact graph-search method, not requiring subjective optimization parameters. The temporal variation of wind fields during the sailing time is accounted for. The system also considers topological constraints such as coastline and shallow waters. The sailboat is modelled in terms of its polar plot. Wind forecasts from multiple providers are accepted as an input. Case studies show that the algorithm consistently computes tacking, jibing, and other route diversions functional to the maximum exploitation of the sailboat performance, as provided through its polar plot. The present version of the system targets races with path lengths in the range of tens of nautical miles or more.

Interactive rate acoustical occlusion/diffraction modeling for 2D virtual environments & games 2D虚拟环境和游戏的交互速率声遮挡/衍射建模
B. Cowan, B. Kapralos
Despite the importance of acoustical diffraction (the "bending" of sound around an obstacle) in the real-world, diffraction in virtual environments and game worlds is often overlooked. Part of this stems from the fact that modeling occlusion/diffraction effects is a difficult and computationally intensive task. Inspired by our previous work that saw the development of a three-dimensional acoustical occlusion method, here we present a method that approximates acoustical occlusion/diffraction effects for dynamic and interactive two-dimensional virtual environments and games (or three-dimensional environments that can be approximated by a two-dimensional mapping). We also discuss an innovative use for the method allowing it to be incorporated into the artificial intelligence of non-player characters (e.g., enemies), allowing them to "perceive" sounds and therefore behave in a more natural, and realistic manner. Preliminary experimental results demonstrate that the method is capable of operating at interactive rates.
尽管声音衍射(声音在障碍物周围的“弯曲”)在现实世界中很重要,但在虚拟环境和游戏世界中的衍射却经常被忽视。这部分源于这样一个事实,即建模遮挡/衍射效果是一个困难和计算密集的任务。受我们之前开发的三维声遮挡方法的启发,我们提出了一种近似动态和交互式二维虚拟环境和游戏(或可以通过二维映射近似的三维环境)的声遮挡/衍射效果的方法。我们还讨论了该方法的一种创新用途,即将其整合到非玩家角色(如敌人)的人工智能中,让他们能够“感知”声音,从而以更自然、更现实的方式行事。初步实验结果表明,该方法能够在交互速率下工作。

In this work the utility of Synthetic Aperture Radar (SAR) data acquired from the SAR instrument on-board the recently launched ESA's Sentinel-1 to Maritime Domain Awareness (MDA) is studied. The limitations of the currently used Automatic Identification System (AIS) for ships is presented. The use of space based SAR sensors for MDA is discussed and the recently available ESA's Sentinel1 satellite is considered in more detail. An automatic methodology for ship detection from Sentinel-1 is presented and applied in the environmentally important sea straits between Kythera and Elafonisos islands, Southern Greece. Preliminary results show that Sentinel1 has a significant role to play in MDA.

A dynamic model for environmentally safe shipping through the Aegean Sea 通过爱琴海的环境安全航运动态模型
Koromila Ioanna, N. Zoe, Giannakopoulos Theodoros, P. Stavros, Charou Eleni, Gyftakis Sotirios
Aegean Sea is an extremely sensitive marine area anticipating a catastrophic event to occur any time now, owing both to hazardous vessel crossing its waters and the significant rise of the intensive traffic. This paper aims to present a probabilistic Bayesian model predicting the probability of a collision, contact or grounding occurrence in the Aegean Sea. The model takes into account the dynamic information of the navigation area and the prevailing weather conditions. The training of the network was performed using the data of the historical accident database of the Marine Rescue Coordination Centre, the National Meteorological Office of Greece and the Aminess database. The whole study has been run within the framework of the AMINESS project.
爱琴海是一个极其敏感的海域,由于危险船只的频繁往来和密集交通的显著增加,随时都有可能发生灾难性事件。本文旨在提出一个概率贝叶斯模型来预测爱琴海发生碰撞、接触或搁浅的概率。该模型考虑了航区的动态信息和当时的天气条件。网络的训练使用了海上救援协调中心的历史事故数据库、希腊国家气象局和Aminess数据库的数据。整个研究是在AMINESS项目的框架内进行的。

This paper aims to present a probabilistic Bayesian model predicting the probability of a collision, contact or grounding occurrence in the Aegean Sea. The model takes into account the dynamic information of the navigation area and the prevailing weather conditions. The training of the network was performed using the data of the historical accident database of the Marine Rescue Coordination Centre, the National Meteorological Office of Greece and the Aminess database.
