Citizen-Centric Data Services for Smarter Cities
(Elsevier, 2016-10-31)
Smart Cities use Information and Communication Technologies (ICT) to manage more efficiently the resources and services offered by a city and to make them more approachable to all its stakeholders (citizens, companies and ...
A domain-independent methodology to analyze IoT data streams in real-time. A proof of concept implementation for anomaly detection from environmental data
(Taylor & Francis, 2016-07)
Pushed by the Internet of Things (IoT) paradigm modern sensor networks monitor a wide range of phenomena, in areas such as environmental monitoring, health care, industrial processes, and smart cities. These networks provide ...
Situation Goodness Method for Weighted Centroid-Based Wi-Fi APs Localization
(Springer, 2016-10-13)
Knowing the location of Wi-Fi antennas may be critical for indoor localization. However, in a real environment, their positions may be unknown since they can be managed by external entities. This paper introduces a new ...
Magnetic field based Indoor positioning using the Bag of Words paradigm
(Institute of Electrical and Electronics EngineersIEEE, 2016-11-17)
In this paper, A Bag of Words based method is presented to test a magnetic field based indoor positioning method. The Indoor positioning problem is solved as a pattern recognition problem, where each reference point is a ...
Providing Databases for Different Indoor Positioning Technologies: Pros and Cons of Magnetic Field and Wi-Fi Based Positioning
(Hindawi Publishing CorporationIOS Press, 2016)
Localization is one of the main pillars for indoor services. However, it is still very difficult for the mobile sensing community to
compare state-of-the-art indoor positioning systems due to the scarcity of publicly ...
Full-Color Stereoscopic Imaging With a Single-Pixel Photodetector
(Institute of Electrical and Electronics Engineers, 2016)
We present an optical system for stereoscopic color imaging by using a single-pixel detector. The system works by illuminating the input scene with a sequence of microstructured light patterns generated by a color digital ...
Roadmap on optical security: Optical encryption by computational ghost imaging
(IOP Publishing, 2016)
Information security and authentication are important challenges facing society. Recent attacks by hackers on the databases of large commercial and financial companies have demonstrated that more research and development ...
Dual-mode optical microscope based on single-pixel imaging
(Elsevier, 2016-03)
We demonstrate an inverted microscope that can image specimens in both reflection and transmission modes simultaneously with a single light source. The microscope utilizes a digital micromirror device (DMD) for patterned ...
Computational imaging with a balanced detector
(Nature Publishing, 2016-06-29)
Single-pixel cameras allow to obtain images in a wide range of challenging scenarios, including broad regions of the electromagnetic spectrum and through scattering media. However, there still exist several drawbacks that ...
An Indoor Positioning System Based on Wearables for Ambient-Assisted Living
(MDPI, 2016)
The urban population is growing at such a rate that by 2050 it is estimated that 84% of the world’s population will live in cities, with flats being the most common living place. Moreover, WiFi technology is present in ...
