Information about urban safety, e.g., the safety index of a position, is of great importance to protect humans and support safe walking route planning. Despite some research on urban safety analysis, the accuracy and granularity of safety index inference are both very limited. The problem of analyzing urban safety to predict safety index throughout a city has not been sufficiently studied and remains...
On the basis of extracting six time-domain features and five frequency-domain ones from vibration signals processed by empirical mode decomposition, an intelligent method to construct a rule-based classifier ensemble for fault diagnosis of rolling bearings was presented. The candidate reducts which could be used to build the base classifiers were found by applying a genetic algorithm for feature reduction...
The occurrence of different types of faults and connection of heavy loads could cause voltage sags in several busbars in distribution grids. In this paper a Susceptible-Infected (SI) epidemic model is proposed to assess the propagation of voltage sags in distribution systems. In the SI model, the infectious nodes are the bus-bars where faults or connection of big loads could occur. On the other hand,...
In hyperspectral images, for detection of vegetation, vegetation index algorithms has been developed by using reflectance / radiance data in the VNIR (Visible Near Infrared) band. In this aspect, green regions in the image can be detected. In this study, a new vegetation index algorithm is developed for SWIR (Short Wave Infrared) hyperspectral images for the purpose of vegetation detection. The effectiveness...
This paper presents a compositional approach to specification-guided abstraction refinement for control synthesis of a nonlinear system associated with a method to over-approximate its reachable sets. The control specification consists in following a lasso-shaped sequence of regions of the state space. The dynamics are decomposed into subsystems with partial control, partial state observation and...
A reachability query with attribute constraints checks whether there is a constraint satisfied path from source to destination in an attributed graph. When an answer 'No' is returned to the user, the user may wonder why there is no such path. The user may ask 'Am I setting the attribute constraint too restrictive?' or 'How can I reach the destination from the source?'. In this paper, we propose the...
We provide a novel upper bound on the rate-distortion function with multiple decoders with side information, which takes the form of a linear program. This complements a recently-obtained lower bound that also takes the form of a linear program. We show that the upper bound is optimal in several instances of the problem1.
Polyp identification in human Gastro Intestinal (GI) Tract employing endoscopy and colonoscopy through various computer vision and image processing techniques has achieved lot of success and maturity in its field. Over the last decade Wireless Capsule Endoscopy (WCE) has emerged as an innovative diagnostic system for identification of ailments such as polyps in GI tract. Polyp detection through WCE...
In many scenarios of interest, agents may only have access to partial information about an unknown model or target vector. Each agent may be sensing only a subset of the entries of a global target vector, and the number of these entries can be different across the agents. If each of the agents were to solve an inference task independently of the other agents, then they would not benefit from neighboring...
In statistics, the concept of a concomitant, also called the induced order statistic, arises when one sorts the members of a random sample according to corresponding values of another random sample. Indeed, multivariate order statistics induced by the ordering of linear combinations of the components arises naturally in many instances. As a contribution, we provide a general second-order statistical...
Dark current (DC) was one of the most critical parameters of CMOS image sensors (CIS), and interface defects during semiconductor fabrication process dominate the DC performance. The research investigated Tx Negative-Bias / P-Well and P+ IMP in this paper, and achieved extreme low DC at high temperature of 60 °C. Firstly, Tx negative bias was used to restrict the Poly/Gate OX/Si substrate interface...
The objective of the proposed system is to develop an adaptive iterative linear regression (ILR) based clustering for wireless sensor network. ILR classifies the initial cluster simultaneously in horizontal and vertical patterns to form two sub clusters. Among these two, the best is selected based on similarity index (SI). This selected cluster is taken as reference and the iteration continues until...
Aimed at the problem of low reliability and low significance level in multi-target threat assessment, based on the advantage of Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method which can take maximizing group effect and minimize individual regret into account, setting reasonable decision-making mechanism coefficient, VIKOR is applied to the multi-target threat assessment problems...
In service function chaining (SFC), end-to-end traffic flows are classified and processed by an ordered set of service functions (SFs). When SF in the chain fails, the corresponding traffic flows cannot be processed further to reach the destination until the failed SF recovers. To cope with the SF failure, failover mechanisms to instantly recover such failed SFs are mandatory. In this paper, we propose...
This article constructs a three dimensional customer segmentation model based on customer lifetime value, customer satisfaction and customer activity, which more accurately divides customers into different groups. The corresponding variables are obtained by RFM model, Kano model and BG/NBD model. The customer segmentation model provides ten groups of customers with corresponding marketing strategies,...
This paper investigates the impact of interrupted and uninterrupted charging strategies of plug-in electric vehicles (PEVs) on the aggregated load profile while considering the user convenience, i.e., the desired state-of-charge of battery at the departure time. First, this paper introduces a new coordinated charging algorithm with interrupted charging intervals. Then, coordinated charging algorithms...
With the development of social network based applications, different service approaches to achieve these applications have emerged. Users' reporting and sharing of their consumption experience can be utilized to rate the quality of different approaches of online services. How to ensure the authenticity of users' reports and identify malicious ones with cheating reports become important issues to achieve...
Myoelectric pattern recognition (MPR) can be used for intuitive control of virtual and robotic effectors in clinical applications such as prosthetic limbs and the treatment of phantom limb pain. The conventional approach is to feed classifiers with descriptive electromyographic (EMG) features that represent the aimed movements. The complexity and consequently classification accuracy of MPR is highly...
In recent years, silicon photonics has attracted attention as an emerging technology for optical telecommunications and for optical interconnects in microelectronics. The refractive index contrast plays a fundamental role in determining the characteristics of an optical dielectric waveguide and a higher index contrast permits to move towards larger scales of integration and to access new devices and...
Riparian forest is an important perceptible ecosystem that preserves the loss of natural filtering of sediment, water quality, wildlife habitat and connectivity with other adjacent landscapes. Agricultural encroachment on the riparian has significant impact on the overall ecosystem of watershed areas. Change detection of the riparian canopy density should be investigated for better management of vegetation...
