Mapping Wifi Measurements On Openstreetmap Data For Wireless Street Coverage Analysis, Andrea Valenzano, Dario Mana, Claudio Borean, Antonio Servetti

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

The growing interest on smart cities and the deployment of an ever increasing number of smart objects in public locations, such as dumpsters, traffic lights, and manholes, requires ubiquitous connectivity for these devices to communicate data and to receive configurations. Opportunistic WiFi connectivity is a valid alternative both to ad hoc solutions, like LoRa, which require costly deployments, and to communicating through the mobile network, which is both pricey and battery power hungry. In this paper we present a tool to analyze the WiFi coverage of home Access Points (AP) on the city streets. It can be of interest to ...

A range of strategies and methods have been developed to mitigate the occurrence of landslides and to reduce their impact, including risk to human safety. The adopted approaches and systems must be sustainable and resilient in relation to the communities that are at risk. This paper refers to an Australian regional case study of urban landslide management in the Wollongong region, New South Wales. The research carried ...


Technology, Hyperbole, And Irony, Alan G. Gross 2018 university of minnesota- twin cities

Technology, Hyperbole, And Irony, Alan G. Gross

Poroi

Except for metaphor, tropes are arguably irrelevant to the analysis of science and technology. Among tropes, moreover, hyperbole and irony seem particularly ill-suited as the former exaggerates, while the latter undermines, two strategies at odds with a language intent on closely following the contours of the world of experience. While neither hyperbole nor irony has a place in the professional discourses of science and technology, both play a role in their popular representations. Hyperbole expresses our sense that these achievements exemplify the sublime, a form of experience applied at first to feelings of awe generated by great literature, then in ...


Multizone Soundfield Reproduction With Privacy- And Quality-Based Speech Masking Filters, Jacob Donley, Christian H. Ritz, W Kleijn 2018 University of Wollongong

Multizone Soundfield Reproduction With Privacy- And Quality-Based Speech Masking Filters, Jacob Donley, Christian H. Ritz, W Kleijn

Faculty of Engineering and Information Sciences - Papers: Part B

Reproducing zones of personal sound is a challenging signal processing problem which has garnered considerable research interest in recent years. We introduce in this work an extended method to multizone soundfield reproduction which overcomes issues with speech privacy and quality. Measures of Speech Intelligibility Contrast (SIC) and speech quality are used as cost functions in an optimisation of speech privacy and quality. Novel spatial and (temporal) frequency domain speech masker filter designs are proposed to accompany the optimisation process. Spatial masking filters are designed using multizone soundfield algorithms which are dependent on the target speech multizone reproduction. Combinations of estimates ...

Faculty of Engineering and Information Sciences - Papers: Part B

In nature, the lateral line of fish is a peculiar and important organ for sensing the surrounding hydrodynamic environment, preying, escaping from predators and schooling. In this paper, by imitating the mechanism of fish lateral canal neuromasts, we developed an artificial lateral line system composed of micro-pressure sensors. Through hydrodynamic simulations, an optimized sensor structure was obtained and the pressure distributionmodels of the lateral surfacewere established in uniformflowand turbulent flow. Carrying out the corresponding underwater experiment, the validity of the numerical simulation method is verified by the comparison between the experimental data and the simulation results. In addition, a variety ...

Faculty of Engineering and Information Sciences - Papers: Part B

IEEE The rapid development of the mobile communications requires ever higher spectral efficiency. The non-orthogonal multiple access (NOMA) has emerged as a promising technology to further increase the access efficiency of wireless networks. Amongst several NOMA schemes, the sparse code multiple access (SCMA) has been shown to be able to achieve better performance. In this paper, we consider a downlink MIMOSCMA system over frequency selective fading channels. For optimal detection, the complexity increases exponentially with the product of the number of users, the number of antennas and the channel length. To tackle this challenge, we propose near optimal low-complexity iterative ...

Real-Time Management Of Groundwater Resource Based On Wireless Sensor Networks, Qingguo Zhou, Chong Chen, Gaofeng Zhang, Huaming Chen, Dan Chen, Yingnan Yan, Jun Shen, Rui Zhou

Faculty of Engineering and Information Sciences - Papers: Part B

Groundwater plays a vital role in the arid inland river basins, in which the groundwater management is critical to the sustainable development of area economy and ecology. Traditional sustainable management approaches are to analyze different scenarios subject to assumptions or to construct simulation–optimization models to obtain optimal strategy. However, groundwater system is time-varying due to exogenous inputs. In this sense, the groundwater management based on static data is relatively outdated. As part of the Heihe River Basin (HRB), which is a typical arid river basin in Northwestern China, the Daman irrigation district was selected as the study area in ...

Depth Pooling Based Large-Scale 3-D Action Recognition With Convolutional Neural Networks, Pichao Wang, Wanqing Li, Zhimin Gao, Chang Tang, Philip O. Ogunbona

Faculty of Engineering and Information Sciences - Papers: Part B

1999-2012 IEEE. This paper proposes three simple, compact yet effective representations of depth sequences, referred to respectively as dynamic depth images (DDI), dynamic depth normal images (DDNI), and dynamic depth motion normal images (DDMNI), for both isolated and continuous action recognition. These dynamic images are constructed from a segmented sequence of depth maps using hierarchical bidirectional rank pooling to effectively capture the spatial-temporal information. Specifically, DDI exploits the dynamics of postures over time, and DDNI and DDMNI exploit the 3-D structural information captured by depth maps. Upon the proposed representations, a convolutional neural network (ConvNet)-based method is developed for ...

Development Of Magnetorheological Elastomers-Based Tuned Mass Damper For Building Protection From Seismic Events, Shuaishuai Sun, Jian Yang, Haiping Du, Shiwu Zhang, Tianhong Yan, Masami Nakano, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part B

This study investigated and evaluated a semi-active tuned mass damper which incorporated four multi-layered structures fabricated using magnetorheological elastomers. The four magnetorheological elastomer structures formed a square and provided the tuned mass damper variable stiffness used to track the excitation frequencies. This design not only increases the stability of the tuned mass damper but more importantly eliminates the magnetic circuit gap in a design which we used in the past because all four of the magnetic circuits used to control the magnetorheological elastomer isolators are closed circuits. In order to verify the capability of the magnetorheological elastomer-based tuned mass damper ...

Behaviour Of Carbon Fibre-Reinforced Polymer-Confined Hollow Circular Concrete Columns With Inner Polyvinyl Chloride Tube, Hussamaldeen GOAIZ, Tao Yu, Muhammad N. S Hadi 2018 University of Wollongong

Behaviour Of Carbon Fibre-Reinforced Polymer-Confined Hollow Circular Concrete Columns With Inner Polyvinyl Chloride Tube, Hussamaldeen Goaiz, Tao Yu, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

Existing studies have shown that the use of an inner tube can significantly enhance the effectiveness of confinement in fibre-reinforced polymer-confined hollow columns. The inner tube used in the existing studies, however, generally had a large stiffness and also served as longitudinal reinforcement. The use of a stiff inner tube is inefficient in resisting bending for hollow columns with a relatively small void and may be unnecessary for constraining the inner surface of concrete. Against this background, this article presents the first experimental study on fibre-reinforced polymer-confined hollow columns with an inner polyvinyl chloride tube. The experimental program included a ...
