Building an Integrated Service Management Platform for Ubiquitous Ecological Cities

Abstract As one of the frontrunners in the race to build smarter cities, South Korea is pushing the envelope by promoting the development of a standard architecture for a service management platform that integrates ubiquitous computing and green technologies. Comments This paper describes a 130 million dollar initiative in South Korea to build a series [...]

Affective Wearable

Abstract An “affective wearable” is a wearable system equipped with sensors and tools which enables recognition of its wearer’s affective patterns. Affective patterns include experessions of emation auch as a joyful smile, an angry gestue, a strained voice or a change in automatic nervous system activity such as an accelerated heart rate or increasing skin [...]

Touch me wear: Getting Physical with Social Networks

Abstract This project explores the possibilities of association between exisitng social network information and real-world physical interaction. The possibilities are explored through the integration of wearables technology with mobile social network technology. We use the term “mobile social networking” to refer to those advanced interactions which integrate complex real world actions with online social network [...]

The Challenges of Wearable Computing, Part I and II

Abstract Wearable computing pursues an interface ideal of a continuoulsy worn, intelligent assistant that augments memory, intellect, creativity, communication, and physical senses and abilities. Many challenges await wearable designers as they balance innovative interfaces, power requirements, network resources, and privacy concerns. This survey describes the possibilities offered by wearables systems, and, in doing so, demonstrates [...]

Towards Biosensing Strategies Based on Biochemical Logic Systems

Abstract Recent advances in biochemical computing, i.e., information processing with cascades of primarily enzymatic reactions realizing computing gates, such as AND, OR, etc., as well as progress in networking these gates and coupling of the resulting systems to smart/responsive electrodes for output readout, have opened new biosensing opportunities. Here we survey existing enabling research results, [...]

Territorial Privacy in Ubiquitous Computing

Abstract Smartphones define a trend towards increasing combination and integration of sensing capabilities with almost ubiquitous inter-connectivity. Resulting location-based services and context-aware applications will benefit users by adapting better to the user application needs. However, there is a lack of effective means for controlling privacy in such systems which will likely increase further with future [...]

PROACT: An ontology-based model of privacy policies in Ambient Intelligence Environments

Abstract Future computing environments involve integrating everyday objects equipped with tiny processors, sensors and wireless network cards. These smart objects (artifacts) may explore their environment and communicate with each other. Interactivity with humans may provide the ability of dealing with tasks in an intuitive way. In order to model the way everyday activities are carried [...]

Location Sensing and Privacy in a Context-Aware Computing Environment

Abstract This article presents and evaluates the performance of a location sensing algorithm developed and demonstrated at Carnegie Mellon University. We compare our model with various others based on different architectures and software paradigms. We show comparative results in accuracy, the complexity of training, total power consumption, and suitability to users. Our method reduces training [...]

ROAD: an RFID Offline Authentication, privacy preserving protocol with Dos resilience

Abstract As RFID applications become widespread, different authentication schemes have been proposed to address the security and privacy issues in RFID systems. Most recent protocols have employed a “central server” model. This kind of authentication is vulnerable to Dos attack. In this paper, we present an RFID Offline Authentication protocol with Dos resilience, ROAD, which [...]

A Framework Ensuring Privacy in a Distributed Environment

Abstract In the age of Internet and loosely coupled applications, privacy has become a matter of concern. Individuals lose track of their personal data and have no control over databases and information systems containing their personal data. In the field of distributed systems, resarchers focus mainly on how to integrate a variety of systems in [...]


Abstract The Apache Hadoop  project develops open-source software for reliable, scalable, distributed computing. The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering [...]

Scaling Social Science with Hadoop

Abstract “The methods of social science are dear in time and money and getting dearer every day.” — George C. Homans, Social Behavior: Its Elementary Forms, 1974……When Homans — one of my favorite 20th century social scientists — wrote the above, one of the reasons the data needed to do social science was expensive was [...]

The Pathologies of Big Data

Abstract Scale up your datasets enough and all your apps will come undone. What are the typical problems and where do the bottlenecks generally surface? Comments An account of issues inherent to big data from an engineering perspective. Informed of constraints in computer hardware and search procedures, the author makes some back-of-the-envelope calculations with simple [...]
