This work proposes a biometrie identification system based on electrocardiographic signal, for online applications. To acquire the signal, the NI MyDAQ and the AD8232 Heart Rate Monitor module were used. Once the signal was digitized, filtering was applied and algorithms to process the signal were designed to detect the fiducial markers of the signal, such as the R peak, the Q wave, the ending of...
Warehouse Management Systems (WMS) play a major role in optimizing warehouse logistic processes, archiving merchant trends of supply and demand, and also easen treating of goods which are close to expiring deadline, out of stock, broken or deposited by customers. Since warehouse management systems may be integrated with business intelligence, they may comprise algorithms for optimization of warehouse...
Brazil has 5.570 cities politically independent and yet entitled to manage urban land, no matter their technical or financial resources for that. Although informal land tenure is commonly associated to major metropolitan areas in Brazil, recent urbanization processes of cities inward the country's territory has led to informal land occupation of entire central districts. Informality is defined, in...
Prioritization of Operation and Maintenance (O&M) and renewal interventions is a key issue for policy making at the urban level. This paper aims at involving citizens in the urban degradation survey process, in order to support strategic decisions of the public administration, through a streamlined process. This contribution belongs to a wider research, aiming at providing a more inclusive approach...
There is an increasing demand for applications in which users can easily browse different events organized by different institutions or organizations in a single place. Among these events are the following: theater or movie shows, cultural programs, presentations, meetups, etc. Most of the institutions (e.g. theaters) have their own web pages, where the programs along with the related news and pieces...
In the last decades, the explosion of the volume of digital document images, and the development of consumer tools to modify these images, has lead to a huge increase on reported fraudulent document cases. This situation has promoted the development of automatic methods for both preventing forgeries in modified documents and detecting them. However, document forensics is a sensitive topic. Data is...
Visual or image-based self-localization refers to the recovery of a camera's position and orientation in the world based on the images it records. In this paper, we deal with the problem of self-localization using a sequence of images. This application is of interest in settings where GPS-based systems are unavailable or imprecise, such as indoors or in dense cities. Unlike typical approaches, we...
Members of international organizations often meet in person at a common location for discussions. There is frequently disagreement over the place and time of the meeting due to the different travel efforts of the members. They usually travel by plane and their travel expenses depend on the flight connections. This paper presents an approach to calculate the optimized location and time, where and when...
In many operations, the US government depends on geospatial data to obtain insights and drive policy making. Federal data are usually pulled from multiple sources, aggregated differently, and formatted in an assortment of standards. Analysts have been overwhelmed by the ample amounts of inconsistent and unstructured data available to them; the main quandary is that they are unable to draw clear conclusions...
In this paper, we propose a cost function that corresponds to the mean square errors between estimated values and true values of conditional probability in a discrete distribution. We then obtain the values that minimize the cost function. This minimization approach can be regarded as the direct estimation of likelihood ratios because the estimation of conditional probability can be regarded as the...
Waste management in Urban Cities of India is a serious concern with growing amounts of uncollected garbage on the streets. In this paper, we present a mobile application based solution to empower the citizens to report instances of uncollected garbage and draw the attention of authorities. Our application has been successfully deployed and has seen more than a million complaints registered across...
The Indian ‘smart cities’ have burgeoning population consuming the intelligent systems running over the city infrastructure and services. One critical set of such services is that of the emergency services involving Ambulances, Police and Firefighters. The services provided by these officials are often time critical, which makes their easy and quick availability a must have attribute. This paper proposes...
In this paper, we address the problem of cross-view image geo-localization. Specifically, we aim to estimate the GPS location of a query street view image by finding the matching images in a reference database of geo-tagged birds eye view images, or vice versa. To this end, we present a new framework for cross-view image geo-localization by taking advantage of the tremendous success of deep convolutional...
This project was motivated by the threat caused by the emerald ash borer, which is spreading across several regions in North America. Mapping of ash trees is an important step in the preparation for a possible infestation of this frightening insect pest, which can destroy endemic ash stands. In this research, the potential of WorldView-2 and 3 images was analyzed to identify ash trees. The study area...
This paper describes a new solution for parking management and control that can be used along with the actual parking system. The proposed solution uses a Web Service as a data controller, a database for data storage and three client applications targeting a better user experience. Web Service's role is to process data received from clients and works as a link between clients and database. Also, Web...
In order to optimize daily activity chains a new approach has to be followed when creating the method and the connected systems architecture. The elaborated method builds on the flexibility of activities, which can be spatial or temporal. With the introduction of flexibility new locations of the activities are suggested to the travellers, so that the optimization can be realized and shorter travel...
White spaces are portions of the TV spectrum that are allocated but not used locally. Ifaccurately detected, white spaces offer a valuable new opportunity for highspeed wireless communications. We propose a new method for white space detection that allows a node to actlocally, based on a centrally constructed model, and at low cost, whiledetecting more spectrum opportunities than best known approaches...
Today the wide and increasing implementation of smart meters on the household level is making it possible to better know the use of electricity by residential consumers. This contributes to improving the quality of the services provided to the consumers and also developing new strategies for planning and operation by the power grid managers. This paper analyses the discovering of patterns in the use...
Determining the location for electric vehicles charging stations within a particular area of interest can be a key factor for a successful deployment. In this paper, an algorithm is developed which calculates the total number of charging stations for a particular model of electric vehicle in an Interstate and US-Highway in between two point cities. The algorithm takes into account design factors such...
Data analysis plays an indispensable role in the knowledge discovery process of extracting of interesting patterns or knowledge for understanding various phenomena or wide applications. Visual Data Mining is further presenting implicit but useful knowledge from large data sets using visualization techniques, to create visual images which aid in the understanding of complex, often massive representations...
