XForms is a language for describing interfaces to data, designed at W3C by researchers from industry and academia. It is a declarative language, meaning it describes what has to be done, but largely not how. The interface it describes does not have to run locally on the machine producing the data, but can be run remotely over the network. Since Internet of Things (IoT) computers typically have little memory and are low-powered, this makes XForms ideally suited for the task.

Home Automation Devices Belong to the IoT World

by Vittorio Miori and Dario Russo

We present a practical and scalable solution that aims to achieve the Internet of Things (IoT) paradigm in complex contexts, such as the home automation market, in which problems are caused by the presence of proprietary and closed systems with no compatibility with Internet protocols.

The Internet of Things (IoT) enables a large number of devices to cooperate to achieve a common task. Each individual device is small and executes a confined software core. Collective intelligence is gained from distributed collaboration and Internet communication. Corresponding IoT solutions form large distributed software systems that pose professional requirements: scalability, reliability, security, portability and maintainability. The C++ Actor Framework CAF [1] contributes such a professional open source software layer for the IoT. Based on the actor model of Hewitt et al. [2], it aids programmers at a good level of abstraction without sacrificing performance.

‘Puzzle’, a mobile end user development framework, allows the end user to opportunistically create, modify and execute applications for interacting with smart things, phone functions and web services. The framework simplifies development of such applications through an intuitive jigsaw metaphor that allows easy composition on touch-based devices. Users immediately identified the utility of this feature, and found it easy to envisage using the framework in various scenarios in their daily lives.

Modern buildings are equipped with a variety of building automation technologies and sensors which are controlled, monitored and managed through heterogeneous information systems. To date, these systems show limited interoperability and tend to operate in isolation. The future will require a more comprehensive and efficient operation of buildings facilitated by way of integrated and smart cooperative management and automation systems. Web-based open-source technologies can create 3D virtual representations of the real-time geolocated activities within a building. Such a system can simplify both the maintenance and operation by facility managers and application services to building occupants.

Advances in electronics and communication technologies are stimulating the growth of low cost connected sensors and actuators. There are many potential application areas, for instance: home automation, security, healthcare, smart grids, integrated transport systems, and next generation manufacturing. To date, research in the area of the Internet of Things (IoT) has largely focused on the sensors, actuators and the communication technologies needed for long battery life and efficient use of spectrum etc. rather than on what’s needed to encourage applications and services. Current IoT products exist in isolated silos. To fully realise the benefits, we will need scalable solutions for managing the vast of amounts of data, and open standards that enable open markets of connected services.

Smart Environments, and in particular Smart Homes, have recently attracted the attention of many researchers and industrial vendors. The proliferation of low-power sensing devices requires integration gateways hiding the complexity of heterogeneous technologies. We propose a ZigBee integration gateway to access and integrate low-power ZigBee devices.

The Internet of Things (IoT) aims to interconnect large numbers of heterogeneous devices to provide advanced applications that can improve our quality of life. The efficient interconnectivity of IoT devices can be achieved with a hybrid Cloud Radio Access Network (Cloud-RAN) and Software Defined Radio (SDR) framework that can overcome the heterogeneity of devices by seamlessly adapting to their communication technology.

The world’s computing infrastructure is becoming increasingly differentiated into autonomous sub-systems (e.g., IoT installations, clouds, VANETs), and these are often composed to generate value-added functionality (systems of systems). But today, system composition is carried out in an ad-hoc, system-specific, manner, with many associated disadvantages. We need a generalized system-of-systems-oriented programming model that allows systems to be composed by application-domain ex-perts, not just systems programmers. Furthermore, composition should occur in a principled way that generates well-understood compositional semantics and behaviour.

Recently proposed IoT platforms are typically based on centralized and cloud-centric infrastructures. The BETaaS project aims at designing a platform for the execution of M2M applications in a distributed runtime environment running close to the physical environment where sensors and actuators are deployed. The main goal is to move the intelligence to the edge in order to allow localized, content-centric, and timely processing of smart objects data. The platform facilitates the integration of existing IoT systems, while providing software developers with a high-level, content-centric abstraction to access smart objects’ resources.

NFC tags and transceivers are ubiquitous and well supported. Like many academic research groups, the Communication Systems Group CSG of the University of Zürich owns many physical devices, which are required for research and teaching. Traditionally, a printed, human-readable inventory and attached labels have been used to keep track of these devices. A new inventory approach was developed with the aim of simplifying the data acquisition using an NFC tag-based system supported by an Android application. This approach was implemented, tested, and used productively. However, due to technical difficulties - namely, a poor response of NFC tags on metallic material - the NFC-based inventory system did not simplify data acquisition and consequently, the NFC-based inventory system was changed back to the label-based system.

TrakChain Estimates Costs for Track and Trace in the Internet of (many) Things

by Miguel L. Pardal and José Alves Marques

The TrakChain assessment tools take a description of a physical supply chain – relevant locations, how many goods are received, how often, etc. – and estimate the performance of track and trace queries in a modelled traceability system, providing predictions of how much processing and storage will be required for the working system. The tools were developed at Instituto Superior Técnico, Universidade de Lisboa, Portugal and were evaluated using a Pharmaceuticals supply chain case study.

W3C Europe will celebrate its twentieth anniversary with a symposium on Tuesday, 5 May in the Paris town hall.

The Web was born in Europe and W3C is celebrating the 20th anniversary of the European branch of W3C in Paris. Europe has played a fundamental role for the success of the Web. First of all, the founding of the World Wide Web Consortium (W3C) in 1994 became possible with the support by CERN, DARPA and the European Commission. Since 1995, when Inria hosted the European branch of W3C, the European Commission funded W3C activities in Europe, as for example the development of Web accessibility rules, enabling people with disabilities to participate equally on the Web. Since 2003, W3C Europe is hosted by ERCIM EEIG.

W3C will celebrate 20 years of work accomplished by European stakeholders for the benefit of the Web with a symposium on 5 May. Speakers will include, among others, representatives from Paris city council, the European Commission and the French government. The closing talk will be given by Tim Berners-Lee, Web Inventor and W3C Director. About 250 invited guests - global strategists, business leaders and developers - are expected to attend.

Over the last 25 years, ERCIM has earned a reputation as one of Europe’s leading expert groups in the areas of ICT and Applied Mathematics. In 2012, the ERCIM community was restructured and is now supported by two organizations, the ERCIM Association (AISBL) and the ERCIM European Economic Interest Group (EEIG). While the Association is carrying out and supervising all of ERCIM’s scientific activities, the EEIG, composed of a subset of the Association's members, is responsible for managing the ERCIM Office and the European branch of the World Wide Web Consortium (W3C).

The ERCIM Office, hosted by Inria in its Sophia Antipolis Research Centre in Southern France, manages all administrative and financial aspects of the ERCIM community with a talented team of professionals.

Hosting and managing the European branch of W3C is a major task of the ERCIM EEIG. The change of the W3C European host from Inria to ERCIM in 2003 aimed at strengthening research relationships throughout Europe to better support Web technology development. ERCIM was a natural candidate as host since many of the European W3C Offices were already based at ERCIM member institutes. When Inria became the first W3C European host in 1995, W3C Europe had 50 members in four countries. Today, the W3C Membership in Europe exceeds 140 organizations, with representation in 20 countries in Europe. But more important, during the last twenty years we have witnessed the Web revolution with tremendous advances in Web technology, changing not only the world of research but also the whole of society. The evolution of Web standards is a challenging task, yet is crucial to maintain an open Web and to transform W3C into a more long-term international standardization organization. This year, W3C Europe will celebrate its twentieth anniversary at an event on Tuesday, 5 May in Paris, in conjunction with the ERCIM Spring meetings, and ERCIM representatives are cordially invited.

The ERCIM Office is also providing assistance and services to the whole ERCIM community. An important activity is the management of European projects involving ERCIM members or the W3C. Through ERCIM, our members have participated in more than 80 projects funded by the European Commission by carrying out joint research activities while the Office manages the complexity of the project administration, finances and outreach. The ERCIM Office also handles ERCIM AISBL financial matters and supports the whole ERCIM community in administrative tasks such as the management of the well established ERCIM Fellowship Programme, and in communications, for example by hosting and maintaining web sites and by producing ERCIM News.

ERCIM has gained a leadership position for cooperating for excellence in research and is a recognized expert organization in Information and Communication Technologies in Europe. To maintain its position, and increase its impact on European strategy and policy, I’m convinced that ERCIM has to increase its membership by attracting the best research performing organizations and by developing new strategically important activities such as the “ERCIM white papers series” started last year with support of Domenico Laforenza, my fellow president of ERCIM AISBL. ERCIM groups of experts identify emerging grand challenges and strategic research topics in Information and Communication Science and Technology (ICST). In 2014, the first two white papers were published on the topics “Big Data Analytics” and “Cyber-Security and Privacy” with recommendations for future research. A white paper on Massively Open Online Courses (MOOCs), another current hot topic, is currently in work.

I also support Domenico’s efforts in cooperating with leading European organisations, in order to play a role in shaping Europe’s digital future through the platform of the European Societies in Information and Communication Sciences and Technologies (EFICST). I encourage ERCIM to strengthen relationships with organisations such as Informatics Europe and the ICT Lab, a Knowledge and Innovation Communities (KICs) of the European Institute for Innovation and Technology (EIT).

With our two organisations, ERCIM EEIG and ERCIM AISBL, I believe that we have the potential to strengthen our position as recognized leader in field of European research and innovation in ICST, to increase our impact on European strategy and policy, and to successfully continue our mission of “Cooperating for Excellence in Research”.

Mesh joinery is an innovative method to produce illustrative shape approximations suitable for fabrication. Mesh joinery is capable of producing complex fabricable structures in an efficient and visually pleasing manner. We represent an input geometry as a set of planar pieces arranged to compose a rigid structure by exploiting an efficient slit mechanism. Since slices are planar, a standard 2D cutting system is sufficient to fabricate them.

In unmanned aerial vehicles, it is vital to be able to detect and accommodate ice adhesion on wings, control surfaces and airspeed sensors, since ice accretion modifies the shape of the aircraft and alters its measurements, thus changing the aerodynamic forces and reducing manoeuvring capability.

The use of unmanned aerial vehicles (UAVs) for civil applications – largely surveillance and monitoring - has increased markedly in recent years. UAVs are very often suited for harsh conditions that are unsafe for humans, such as those typically encountered in Arctic operations. Reliable, appropriate, and efficient UAV operations are needed in such conditions.

Mobile applications, web services and social media generate huge data traffic from many sources. This is described as ‘big network data’ with the ‘4V-characteristics’ - that is, variety, velocity, volume and veracity. Analysis on such big network data can discover problems, reveal opportunities and provide advice for the service and network providers for fine-grained traffic engineering with close to real-time adjustment or application acceleration [1].

An earlier article in ERCIM News described a system for cooling integrated circuits with re-usable hot water. The result is a sharp increase in energy efficiency and a sharp reduction in the carbon footprint of data centers. The same technique is being applied to photovoltaic electrical energy production, again with a huge gain in system efficiency due to the parallel recovery of waste heat. In hot climates heat from datacenters as well as solar systems is converted into cooling by means of adsorption heat pumps.

The German VAVID project develops improved techniques for data compression as well as new methods of data analysis, data management and interactive data visualization.

In February an interview with Guido van Rossum was published on the ACM website, celebrating 25 years of Python. This popular programming language originates from CWI in Amsterdam, where Van Rossum designed Python in December 1989 and finished the first working version in the first months of 1990. He named the language after his favourite British comedy series Monty Python's Flying Circus.

Researchers from the Formal Methods group at CWI fixed a bug in programming language Java in February 2015. They found an error in a broadly applied sorting algorithm, TimSort, which could crash programs and threaten security. The bug had already been known from 2013 but was never correctly resolved. When researcher Stijn de Gouw attempted to prove the correctness of TimSort, he encountered the bug. His bug report with an improved version has now been accepted. This version of TimSort is used by Android.
