This paper describes a design flow for data-dominated embedded systems. We use The Mathworks' Simulink£ ¥ ¤ environment for functional specification and algorithmic analysis. We developed a library of Simulink blocks, each parameterized by design choices such as implementation (software, analog or digital hardware, ¦ § ¦ ¨ ¦) and numerical accuracy(More)
In this paper, a novel online mutual coupling compensation algorithm especially tailored to uniform and linear arrays is presented. It is conceived to simultaneously compensate for mutual coupling and estimate the direction-of-arrivals (DOAs) of signals impinging on the array since the estimated calibration matrix can be embedded within any classical(More)
Inertial navigation systems (INS) are aimed at supporting the navigation of objects and/or users making use of a computer equipped with motion (accelerometers) and rotation (gyroscopes) sensors to continuously calculate their motion and position. These are quite useful when the GPS signal is not available, such as in indoor scenarios. Thanks to the(More)
In this work we present a pedestrian navigation system for indoor environments based on the dead reckoning positioning method, 2D barcodes, and data from accelerometers and magnetometers. All the sensing and computing technologies of our solution are available in common smart phones. The need to create indoor navigation systems arises from the(More)
This article describes a programming experiment in which an entire city is the playground. Building on the foundation of the SmartSantander FIRE infrastructure, the CityScripts project proposes an Internet of Things scenario where sensors and actuators in a smart city have digital counterparts and can be used to compose mash-ups with Internet of Things(More)
This paper describes a work-in-progress programming experiment where the playground is an entire city. Based on the SmartSantander FIRE infrastructure, the City Script project is aimed at integrating and experimenting a Web of Things scenario in which sensors and actuators in the city have a digital counterpart and can eventually used to compose mashups(More)
Engineering of negotiation model allows to develop effective heuristic for business intelligence. Digital Ecosystems demand open negotiation models. To define in advance effective heuristics is not compliant with the requirement of openness. The new challenge is to develop business intelligence in advance exploiting an adaptive approach. The idea is to(More)
