NoiseSPY: a real-time mobile phone platform for urban noise monitoring and mapping

In this paper we present the design, implementation, evaluation, and user experiences of the NoiseSpy application, our sound sensing system that turns the mobile phone into a low-cost data logger for monitoring environmental noise. It allows users to explore a city area while collaboratively visualizing noise levels in real-time. The software combines the sound levels with GPS data in order to generate a map of sound levels that were encountered during a journey. We report early findings from the trials which have been carried out by cycling couriers who were given Nokia mobile phones equipped with the NoiseSpy software to collect noise data around Cambridge city. Indications are that, not only is the functionality of this personal environmental sensing tool engaging for users, but aspects such as personalization of data, contextual information, and reflection upon both the data and its collection, are important factors in obtaining and retaining their interest

A Visual Analytics Process for Exploring Risk and Vulnerability in International Food Trade Networks

abstract: The rise in globalization has led to regional climate events having an increased effect on global food security. These indirect first- and second-order effects are generally geographically disparate from the region experiencing the climate event. Without understanding the topology of the food trade network, international aid may be naively directed to the countries directly experiencing the climate event and not to countries that will face potential food insecurity due to that event. This thesis focuses on the development of a visual analytics system for exploring second-order effects of climate change under the lens of global trade. In order to visualize how climate change impacts the world trade network of agricultural goods I have developed an interactive data visualization platform for analysis of the interaction between climate events and the trade network. The proposed visual analytics system focuses on visualizing current trade dependencies at a more granular level than the currently available tools and to aid in the identification of future vulnerabilities. To demonstrate the applicability of the tool, two case studies are described. The first case study focuses on the Chinese drought of 2011 and its impact on the global trade network and food security. The second case study will model the potential impact of a climate event affecting production in the United States, a large supplier of corn, to demonstrate the potential consequence of cascading effects in the global trade network.Dissertation/ThesisMasters Thesis Computer Science 201

Interconnecting GRRASP with additional platforms and tools: A feasibility study

As it has already been documents in several reports, the Geospatial Risk and Resilience Assessment Platform (GRRASP) under development ad the JRC is a World Wide Web oriented architecture bringing together geospatial technologies and computational tools towards the objective of supporting the analysis of critical infrastructures (CIs) A key aspect of this platform is its capability to serve as the vehicle to interlink the analysis modules and tools that over the years have been developed by the scientific community towards a one-stop-shop for critical infrastructure risk and resilience analysis. The present report illustrates how the software architecture of GRRASP has been designed and is being exploited to support the integration of GRRASP with different projects related to the analysis of CIs.JRC.E.2-Technology Innovation in Securit

A Review of the Enviro-Net Project

Ecosystems monitoring is essential to properly understand their development and the effects of events, both climatological and anthropological in nature. The amount of data used in these assessments is increasing at very high rates. This is due to increasing availability of sensing systems and the development of new techniques to analyze sensor data. The Enviro-Net Project encompasses several of such sensor system deployments across five countries in the Americas. These deployments use a few different ground-based sensor systems, installed at different heights monitoring the conditions in tropical dry forests over long periods of time. This paper presents our experience in deploying and maintaining these systems, retrieving and pre-processing the data, and describes the Web portal developed to help with data management, visualization and analysis.Comment: v2: 29 pages, 5 figures, reflects changes addressing reviewers' comments v1: 38 pages, 8 figure

Система визначення глибини зображення

Робота публікується згідно наказу Ректора НАУ від 27.05.2021 р. №311/од "Про розміщення кваліфікаційних робіт здобувачів вищої освіти в репозиторії університету" . Керівник роботи: к. т. н., ст. викл. кафедри авіаційних комп’ютерно-інтегрованих комплексів, Василенко Микола ПавловичIn today's world, there is often a question about creating a model to solve a certain problem in such a way that it performs its intended task properly and does not have a large cost. This is what almost every developer of the project wants at the production stage. Thus, the work consists in improving and acquiring better accuracy of the image depth detection system. For this, was modified and improved, namely, the main design of the model was changed and the quality of the image was improved, thanks to various methods of image filtering. Unlike the previous model, this project investigates the effect and quality of the 3D scene construction in the image, not the streaming video, under different weather conditions and at different observation points, which makes it possible to feel in more detail the impact of various phenomena on the model itself during operation and improve accuracy due to considering a single pair of images rather than a stream of large numbers at a specific frequency. The design consists of two cameras, which were selected from the principle of price-quality, and a box to fix and protect the model itself, thus forming protection from the environment in various conditions of use. The design is connected to a computer that performs the software part, which consists in creating a stereo pair – artificial adjustment of cameras, image analysis at the initial stage and after filtering, which as a result gives an opportunity to see the difference in the accuracy of constructing a 3D image, which can be used for various goals, for example to find out the size or distance to the target object.У сучасному світі часто постає питання про створення моделі вирішення певної задачі таким чином, щоб вона якісно виконувала поставлене завдання і не мала великих витрат. Це те, чого хоче практично кожен розробник проекту на етапі виробництва. Таким чином, робота полягає в удосконаленні та підвищенні точності системи визначення глибини зображення. Для цього виготовлена модель була модифікована та вдосконалена, а саме змінено основну конструкцію моделі та покращено якість зображення, завдяки різним методам фільтрації зображення. На відміну від попередньої моделі, цей проект досліджує ефект і якість побудови 3D-сцени в зображенні, а не в потоковому відео, за різних погодних умов і в різних точках спостереження, що дає можливість більш детально відчути вплив різних явищ. на самій моделі під час роботи та підвищити точність за рахунок розгляду однієї пари зображень, а не потоку великих чисел із певною частотою. Конструкція складається з двох камер, підібраних за принципом ціна-якість, і коробки для кріплення і захисту самої моделі, формуючи таким чином захист від зовнішнього середовища в різних умовах використання. Конструкція підключена до комп’ютера, який виконує програмну частину, яка полягає у створенні стереопари – штучне налаштування камер, аналіз зображення на початковому етапі та після фільтрації, що в результаті дає можливість побачити різницю в точності. побудови тривимірного зображення, яке можна використовувати для різних цілей, наприклад, щоб дізнатися розмір або відстань до цільового об'єкта

Enhanced Version Control for Unconventional Applications

The Extensible Markup Language (XML) is widely used to store, retrieve, and share digital documents. Recently, a form of Version Control System has been applied to the language, resulting in Version-Aware XML allowing for enhanced portability and scalability. While Version Control Systems are able to keep track of changes made to documents, we think that there is untapped potential in the technology. In this dissertation, we present novel ways of using Version Control System to enhance the security and performance of existing applications. We present a framework to maintain integrity in offline XML documents and provide non-repudiation security features that are independent of central certificate repositories. In addition, we use Version Control information to enhance the performance of Automated Policy Enforcement eXchange framework (APEX), an existing document security framework developed by Hewlett-Packard (HP) Labs. Finally, we present an interactive and scalable visualization framework to represent Version-Aware-related data that helps users visualize and understand version control data, delete specific revisions of a document, and access a comprehensive overview of the entire versioning history
