T1.  Diversity-aware Multilingual Lexical Semantic Resources        Management
Dr. Abed Alhakim Freihat, University of Trento, Italy
Knowledge management requires cross-language and multicultural        elements. In fact, the management of knowledge is widely spread in        different nations, where each culture has its own knowledge base.        To connect different language knowledge bases, the construction of        a cross-language knowledge base is required to translate        knowledge.  Building such  multilingual lexical resources involves        the participation from different cultures and languages which         leads in turn  to diversity,  a fundamental phenomenon  in        multilingual lexical resources development.
 In this tutorial, we introduce Universal Knowledge Core (UKC), A        diversity-aware multilingual conceptualization of the world which        enables the construction of diverse but coordinated,        representations of the world.
 In particular, we give an overview of
  * Lexical semantic resources
  * Managing multilinguality in lexical semantic resources
  * The Universal Knowledge Core (UKC)
  * Localization of the UKC
  * Diversity management in the UKC
   
  T2. Passive Remotely Controlled SAW (Surface Acoustic Waves)        Sensors and SAW RFID tags
  Prof. Dr. Victor Plessky, GVR Trade SA, Switzerland
In the lecture the main ideas of passive remotely controlled sensors and  RFID-tags based on Surface Acoustic Waves (SAW) will be presented. We will  discuss “reflective delay line” type of SAW devices, which are similar for both  sensor and SAW-tag applications. SAW tags were invented many years ago, but nowadays  all conditions are united for mass application of this technology. The devices  in the 2.4-GHz ISM band can be routinely produced with optical lithography, and  high-resolution interrogation systems (the “readers”) can be built up using  highly sophisticated, but low-cost RF-chips. The SAW tags can overcome  semiconductor-based analogs in many aspects: they can be read at a distance of  a few meters with readers radiating power levels 2 to 3 orders lower, they are  cheap, and they can operate in robust environments. Passive SAW tags can be  easily combined with sensors. Even the "anti-collision" problem  (i.e., the simultaneous reading of many nearby tags) have adequate solutions  for many practical applications. In this lecture, we will discuss the state-of-the-art  in the development of SAW tags. The design approaches will be reviewed and  optimal tag designs, as well as encoding methods, will be demonstrated. We will  also discuss ways to reduce the size and cost of these devices. A few practical  examples of tags using the “time position coding” with 106 to 109  different codes will be demonstrated. Phase-coded devices can further increase  the number of codes at the expense of reduction of reading distance. We also  discuss new and exciting prospects of using ultra-wide-band (UWB) technology  for SAW-tag systems and SAW-sensors. The wide frequency band available for this  standard provides a great opportunity for SAW tags to be radically reduced in  size to about 1 x 1 mm2 while keeping a practically infinite  number of possible different codes.  Recent new approach based on Hyperbolically  Frequency Modulated (HFM) UWB signals will be discussed in detail with  demonstration of new experimental results. Using UWB chirp signals with this  modulation allows to increase the reading distance, and to achieve higher  sensitivity of SAW sensors. 
No preliminary  knowledge about SAW is demanded for understanding this Tutorial Lecture. 
    
    T3.  Research on Smart Cities – Solving Problems of Urbanization
  Prof. Dr. Lasse Berntzen, University College of Southeast        Norway, Norway
“Smart cities” can be explained from different  perspectives. Most        definitions emphasize the use technology to provide better        services, reduced environmental footprint, more participation, and        better quality of life. As a research topic, “smart cities”        includes the study of service delivery, environmental policies and        technologies, electronic participation, citizen centricity and        many other issues. Researchers may explore the “smart city” as a        highly complex system, or dive into the many different application        areas of “smart city” thinking.  The application areas primarily        aim to solve problems of urbanization caused, e.g., by heavy        traffic, increased energy use, high pollution, and large amounts        of waste. But “smart cities” is also about innovation in major        public sectors, such as education, health, public safety and        social services. The research is often multi-disciplinary,         bringing together engineers, computer scientists,        environmentalists, urban planners, sociologists, economists, and        other academic disciplines.
Inexpensive hardware platforms such as the Raspberry Pi, Intel        Edison, Arduino, paired with ecosystems of sensors, enable us to        deploy sensor technology on a large scale. The sensor data,        combined with data from open data sources and social media, can be        analysed and used for predictions and decision-making. New        visualization techniques make results easier to understand by both        citizens and decision-makers.
Infrastructure, both fixed and mobile, let citizens access        services, report problems, and engage in democratic processes.        Mobile devices and smartphones provide access from everywhere at        any time. Smart meters provide almost real-time information on        energy use, and make it possible to adjust power consumption        according to costs.
Several large global companies are marketing “smart city”        solutions. Their focus is mostly on technology and integration of        subsystems into a holistic solution for managing and running the        city.
But “smart cities” reaches far beyond technology. “Sustainable        smart cities” is about energy efficiency, reduced environmental        footprint, and better traffic solutions. “Shared smart cities” is        drawing attention to innovation practices of smart cities. “Smart        places” is advocating smart city values as universal, independent        of city size. Citizens choose smaller places to get cleaner air        and better quality of life, and they certainly need digital        services even more than citizens of the large cities.
The tutorial will first examine examples of conceptual frameworks        and efforts to benchmark smart cities. The tutorial aims to show        the broad spectrum of research on smart cities. Some projects will        be described in detail, including a solution for air quality        monitoring, a solution for traffic monitoring, a study of the role        of citizens in smart cities, and a project to improve citizen        participation.
