This paper introduces a simulation environment developed for analyzing crowd-sensing based applications in the Smart City application domain. As a case study, an urban parking application scenario is investigated and presented. In this scenario, smart citizens collect and share parking related events, such as leaving or occupying a free parking spot. These events can be presented on a real-time city...
The paper focuses on building the mathematical model of a filling/drainage process (namely ASTANK2), by analytical approach. Models are subsequently tested by simulation. The process is versatile: it consists of two tanks with different geometric shape, which could be considered in independent or coupled setup and are supplied by an adjustable water distribution pipelines network. The proposed model...
Owing to their high efficiency and power density, high-speed permanent magnet (PM) brushless machines are emerging as a key technology for applications as varied as spindle drives, centrifugal compressors, turbo-molecular pumps, gas-turbine generator units, and electric/hybrid vehicle traction systems [1].
The Induction motors (IMs) for Electric Vehicle (EV) have an advantage of the low-cost and making it easier to manufacture of rotor as compared with other motor in industries [1].
The performance of the activated sludge process is limited by the ability of the sedimentation tank to separate the activated sludge from the treated effluent and to concentrate it. Apart from bad operating strategies or poorly designed clarifiers, settling failures can be mainly attributed to filamentous bulking. Image analysis is a promising technique that can be used for early detection of filamentous...
The v-gap analysis can be used to analyze the achievable robustness for a control system before designing any controllers. In its unweighted form, the v-gap promises powerful results. However, for practical applications, dynamic weights must be introduced, and then the results are with respect to this given choice of weights. For this weighted case, H∞ analysis provides a simpler alternative and yields...
In this paper non-Gaussian noise modelling is addressed, HOS-based parametric pdf models are investigated in order to provide realistic noise modelling by means οΓ easy and quick estimation of needed parameters. Attention is focused on the generalized Gaussian pdf. This model, generally depending on a real theoretical parameter c. difficult to estimate from data, is proposed expressed in terms of...
Statistical shape models generally characterize shape variations linearly by principal component analysis (PCA), which assumes that the non-rigid shape parameters are drawn from a Gaussian distribution. This practical assumption is often not valid. Instead, we propose a constrained local model based on independent component analysis (ICA) and use kernel density estimation (KDE) for non-parametrically...
This work considers the task of estimating the source and filter from human voice signals. Since the energy of voiced sound concentrates on discrete frequencies, a notable challenge with this task would be that higher pitches in the signal can make the harmonically related frequency response samples of the vocal tract filter an incomplete representation. In view of this, we propose to model the magnitude...
The segmentation of networks is important in several imaging domains, and models incorporating prior shape knowledge are often essential for the automatic performance of this task. We incorporate such knowledge via phase fields and higher-order active contours (HOACs). In this paper: we introduce an improved prior model, the phase field HOAC ‘inflection point’ model of a network; we present an improved...
Graphical user interfaces (GUIs) are integral parts of software systems that require interactions from their users. Software testers have paid special attention to GUI testing in the last decade, and have devised techniques that are effective in finding several kinds of GUI errors. However, the introduction of new types of interactions in GUIs (e.g., direct manipulation) presents new kinds of errors...
An experimental analysis of two-dimensional (2D) shape classification method based on moment invariants is presented. Various types of translation, scale and rotation invariants are used to construct feature vectors for classification. The performance is evaluated using five different objects picked up from real scenes with a TV camera. Silhouettes and contours are extracted from nonoccluded 2D objects...
This paper investigates effect of substrate thickness on energy drift from anchor of mechanical resonators. A finite element (FE) method is utilized to capture energy loss from the anchor. To eliminate wave reflection from the outer boundaries of the resonator substrate model, a perfectly matched layer is used. This artificial layer absorbs waves before they reach to the outer boundaries of truncated...
Although extant research convincingly argues that managers can change product innovation practices by exploiting new forms of generativity afforded by digital technology, the literature has so far been silent on how incumbent firms may conceive of and implement requisite generative capability. Against this backdrop, we report from an action research study into a digital innovation initiative aimed...
This paper describes a new model for studying impulse noise in metallic lines and offers theoretical base for modeling of impulse noise in digital communication systems intended for use with medium-voltage power distribution lines.
We are developing the OpenPET which can provide an open space to make the patient observable and accessible during PET measurements. One of the key technologies for realizing the OpenPET geometry is the depth of interaction (DOI) detectors because the geometry has many oblique lines of response (LORs). Even if the DOI detectors reduce the blurring effect of the thick crystals, it is important to model...
One emerging and challenging issue in Smarter Cities is Mobility. In order to gather mobility data for relevant analyses, two solutions are widely discussed, namely the conventional standardized infrastructure sensors and the novel social sensing solution. However infrastructure sensors solution is too costly, that is unfeasible for every city. On the contrast, social sensing is a renewal approach,...
Vehicle classification system is an important part of intelligent transportation system (ITS), which can provide us the necessary information for autonomous navigation, toll systems, surveillance and security systems, and transport planning. In this paper, we introduce a vehicle classification system based on dynamic Bayesian network (DBN). Three main types of features are employed in our system:...
From the literature, we know that regular hexagonal coverage is the optimal seamless coverage for terrestrial wireless network, i.e. cellular network [1], as it could achieve minimum handover rates compared with other seamless coverage like triangle coverage, rectangle coverage and etc [2][3][4]. However, different from the terrestrial wireless network, both the movements of user equipments (UEs)...

In order to construct 3D model of the surface topography the authors have proposed the use of height maps and...
