The increasing use of renewable energy sources, together with an ever-increasing energy demand, puts the electrical grid under heavy pressure. Grid extensions mitigate these factors, but are very costly. Other methods enabling an economically viable energy transition towards more renewable energy sources should be explored. We present a preliminary assessment of the impact of different mixes of prosumers on the energy balance and self-consumption of a rural community. We quantify unused potential regarding demand-side management, the extension of photovoltaic peak power, as well as battery storage. We implement models for electric production and consumption profiles and simulate scenarios with varied prosumer compositions. The results show that demand-side management does not change the self-consumption of photovoltaic energy significantly, whereas installation of more battery storage together with increased photovoltaic production promises better results for the rural community studied.

In many applications, humans remotely control a robot through teleoperation, to augment its capabilities with the cognitive skills of humans. The arrival of mainstream head mounted displays (HMDs) and 360° cameras have brought about reduction in their size, increase in functionality as well as lowering of cost. This paper presents an augmented telepresence system using a HMD for remote operation of a legged robot via a web application. Low-cost and low-weight hardware were chosen to realise the system on a legged robot platform, but the web technologies used are device-agnostic and work efficiently across multiple platforms. A mock-up remote visual inspection test course was used to experimentally evaluate the HMD system by comparing performance with a fixed camera display approach. A total of 28 individual operators completed the test course with course completion performance recorded along with user feedback. The results show that the HMD increased the operator's perception of the remote environment but there are no significant task performance advantages using a HMD for remote inspection with legged robots.

Autonomous systems are able to make decisions and potentially take actions without direct human intervention, which requires some knowledge about the system and its environment as well as goal-oriented reasoning. In computer systems, one can derive such behavior from the concept of a rational agent with autonomy (“control over its own actions”), reactivity (“react to events from the environment”), proactivity (“act on its own initiative”), and sociality (“interact with other agents”) as fundamental properties \n[1]\n. Autonomous systems will undoubtedly pervade into our everyday lives, and we will find them in a variety of domains and applications including robotics, transportation, health care, communications, and entertainment to name a few. \nThe articles in this month’s special issue cover concepts and fundamentals, architectures and techniques, and applications and case studies in the exciting area of self-awareness in autonomous systems.

NICT has developed a testbed of device-to-device communication networks for the purposes of information collection and distribution among local communities. With the cooperation of local administrations, the testbed was deployed in the Odaiba area of Minato City of Tokyo as well as in Seika Town of Kyoto, respectively, in 2014. The Odaiba area and Seika Town are respectively used as a typical urban model and a typical rural model. All devices of the testbed are installed at 920 MHz frequency band. On one hand, various devices of the testbed are installed in the community buses including 'Odaiba Rainbow Buses' operated by Minato City as well as 'Seika Kururin Buses' operated by Seika Town. On the other hand, devices of the testbed are deployed in the surroundings of bus routes. Various experiments have been being conducted since then. None of devices performs central coordination in the testbed. Devices communicate each other autonomously when they are within communication range. Consequently, any single device doesn't have dominant effect to the entire network. Such features enable robust communication networks during emergency situation such as disasters. Devices installed in buses communicate with surrounding devices anywhere within range and exchange information each other, so that local area information are collected and distributed as buses move. Moreover, by receiving the location information sent from the running buses across all bus routes, we construct a bus location guidance system. The developed device-to-device communication networks for information sharing at local community are independent from cellular and other existing wireless networks and various applications can be expected. © 2017 National Institute of Information and Communications Technology.

Despite extensive developments in the field of Acoustic Emission (AE) for monitoring fatigue cracks in steel structures, the implementation of AE systems for large-scale bridges is hindered by limitations associated with instrumentation costs and signal processing complexities. This paper sheds light on some of the most important challenges in the utilization of AE systems for steel bridge decks. These challenges are mainly related to the multi-modal character of guided waves, and the expensive installation of AE instrumentation. A quasi-beamforming solution which alleviates the above-mentioned challenges was introduced and successfully evaluated on a real-scale bridge segment in a laboratory environment. The solution was also implemented on a real bridge structure, demonstrating the benefit of the proposed configuration where the transducers are closely spaced for reduced installation costs.

Comparing experimental results obtained on diferent wireless sensor network deployments is typically very cumbersome and in most cases unfeasible. This is due to the lack of a methodology to describe the properties of network deployments and the experimental conditions under which experiments have been run. Our work focuses on the design and development of a site properties assessment framework, called SiteWork, that aims at providing the means to quickly, automatically and accurately quantify their properties. This poster abstract describes the preliminary design and evaluation of the basic site properties assessment mechanisms provided by SiteWork.

This paper introduces a novel approach for abstraction selection in reinforcement learning problems modelled as factored Markov decision processes (MDPs), for which a state is described via a set of state components. In abstraction selection, an agent must choose an abstraction from a set of candidate abstractions, each build up from a different combination of state components.

IEEE Workshop on Signal Processing Advances in Wireless Communications

Wireless sensor network protocols and applications typically need to be evaluated and tested not only using simulators but also on testbeds. While simulations allow studying the performance of protocols and applications in a controlled environment, they usually do not provide a sufficient level of. realism. On the contrary, testbeds allow exposing protocols and applications to the real vagaries of wireless communication as well as to other "non-idealities" that typically occur in real wireless sensor network scenarios. Experimental results gathered in one or more testbeds are thus typically reported in most recent research papers on wireless sensor networks. Usually, the higher the number of different testbeds has been used, the more significant the obtained results are considered to be. However, it is often unclear whether the used testbeds actually expose protocols and applications to significantly different experimental conditions. Experiments involving a high number of testbeds are very time-consuming and cumbersome to run, but cannot guarantee that a protocol or application has been evaluated or tested in significantly different scenarios. In this paper, we argue that a systematic methodology that allows describing how significant the differences between testbeds actually are is needed. As a first step towards the definition of this methodology, we define several quantitative properties that can be used to describe and compare testbeds in a coherent manner. We show how a representative subset of these properties can be computed in real testbeds and present the results obtained by running this computation on two different testbeds. Furthermore, we describe how we plan to use our methodology to allow researchers to automatically select - out of a set of testbeds - those that are most adequate to run a specific experiment.
