Incidents involving data breaches are ever-present in the media since several years. In order to overcome this threat, organizations apply enterprise content-aware data leakage prevention (DLP) solutions to monitor and control data access and usage. However, this paper argues that current solutions are not able to reliably protect information assets. The analyses of data breaches reported in 2014...
Online social networks are a popular and important channel for people to share, find and disseminate information on a massive scale. Some of the information exposed through these networks is meant to be private. However, sensitive organizational information can be accidentally leaked by employees and become exposed to adversaries or competitors. The threat is escalated due to socialbots used by adversaries...
This paper proposes a novel network architecture for optimal and balanced provision of multimedia services, exploiting a resource prediction system. This architecture enables for the long-term prediction of multimedia services future demands, based on the history of previous network resources usage. The proposed research approach provides the opportunity for the optimal distribution of streaming data,...
The rapid growth of social media and the ubiquitous availability of audiovisual content have transformed virtually every aspect of our personal and professional lives. In Internet-based multimedia applications users with their activity (including social life) are both the source of data and the consumers of the applications, hence being involved in the creation of user-oriented business value. In...
Information and Data security is of high concern for almost all organizations. Intrusion though can be dealt with use of firewalls, better and much improved ways of detecting intrusions are through advanced software, but some non technical issues may also lead to unauthorized access, if ignored. This paper attempts to discuss these issues. A survey was conducted and responses regarding cyber security...
Real-time road traffic congestion monitoring is an important and challenging problem. Most existing monitoring approaches require the deployment of infrastructure sensors or large-scale probe vehicles. Their installation is often expensive and temporal-spatial coverage is limited. Probe vehicle data are oftentimes noisy on urban arterials, and therefore insufficient to provide accurate congestion...
Enabling and controlling elasticity of cloud computing applications is a challenging issue. Elasticity programming directives have been introduced to delegate elasticity control to infrastructures and to separate elasticity control from application logic. Since coordination models provide a general approach to manage interaction and elasticity control entails interactions among cloud infrastructure...
Media streaming services are responsible for the significant increase of Internet traffic. This fact generates the need for better computing resources management in order to maintain such services always available. Cloud computing offers an elastic infrastructure that provides computing resources on demand in order to maintain such services always available. Moreover, emerging network architectures,...
Non-Intrusive Load Monitoring (NILM) Systems are one of the main proposals to characterize the household power consumption. This work proposes an alignment method based on the low frequency band power consumption which overrides the high frequency noise. To this end, a Gaussian kernel its used to smooth the power signal in order to obtain the right time where a device is turned on, and therefore making...
In Smart Grid applications, we need to access end devices for monitoring and control over varieties of communication media (e.g., wireless, wired and power-line communications). The Internet Protocol is useful because it can integrate those heterogeneous media by IP over X architecture. In this paper, we focus on the integration of RS485, an optimal communication media for facility networking in buildings,...
In this paper the beginning of the national training project for distribution operators (OD's, for its acronym in Spanish), that daily are involved in the management and administration of the medium and low voltage electrical system, is documented. To carry out this project, the Alternate National Center (CENALTE, for its acronym in Spanish) of the Federal Electricity Commission (CFE, for its acronym...
The proliferation of the Internet technology has contributed to an increasing demand for streaming applications. The adaptation of multimedia streaming content according to context information is essential to supporting these applications. In this paper, we design a context-aware multimedia quality adaptation framework for smart streaming. The proposed framework seamlessly provides multimedia data...
Embedded network systems use serial communication protocols and simplified media access control schemes in order to exchange information among several interconnected nodes. Within this paper a generalization of the classical media access control (MAC) protocols used in small embedded serial networks of microcontrollers is investigated and an implementation platform for testing the proposed MAC schemes...
We present preliminary data and information collected from microblogs during the 2014 seasonal flu vaccination in Brasil. A quantitative analysis of tweets compiled over 50 days is reported. A categorization analysis of these tweets in three major axis: content, qualifier and links, is described and preliminary results are revealed. A comparison with the data collected during the H1N1 outbreak in...
A video frame extractor applying analog video input signals for omni media monitoring system is given in order to meet the increased requirements for rapid development of radio & television industries. The extractor employs advanced RISC machine (ARM) processor S3C2440 with embedded Linux operating system as host processor, field programmable gate array (FPGA) EP3C25 as coprocessor, increasing...
In this paper, we present a home sleep care system to monitor function of activity measurement and sleeping position estimation via vision-based algorithms. The outcomes are integrated in a telecare middleware with a hierarchical software stack and visualized by a structural subsystem. Since smart TVs play an important role in home tele-healthcare system, we centralize and display additional sleep...
A serious impediment in E-Learning is that these systems seem to have failed to consider the advantages of the supervision of a teacher. Teachers are able to monitor the progress made by several students, irrespective of their learning abilities and attempt to channel all students towards a common learning goal. E-Learning systems today don't possess a monitoring component. Most approaches customize...
We presents an ion sensitive field effect transistor to measure the pH of the cell culture media of human mammary adenocarcinoma (SKBR3). We use a drift mitigation technique that cycles the transistor to reset the drift in the system. We use to technique in the system to demonstrate an integrated system to monitor the pH continuously. As a part of the system a pulse width modulation circuit is designed...
Due to the rapid development of Internet technology, the greater demand for multimedia services causes the traffic collisions increasing. 3rd Generation Partnership Project (3GPP) specified IP Multimedia Subsystem (IMS) for next generation network service. For the real-time multimedia service such as video streaming, it requires a large amount of bandwidth resource. Besides, the different ongoing...
Em uma refinaria de petróleo trabalha-se com grandes quantidades de produtos inflamáveis a altas pressões e temperatura, e mantê-los sob controle é uma tarefa árdua. Manter o sistema elétrico durante um distúrbio é fundamental, não só para garantir a continuidade operacional, mas também reduzir o impacto ambiental e preservar a segurança das instalações e das pessoas que nelas trabalham. é neste contexto...
