Personally Identifiable Information (PII) includes any information that can be used to distinguish or trace an individual’s identity such as name, social security number, date and place of birth, mother’s maiden name, or biometric records. It also includes other information that is linked or linkable to an individual, such as medical, educational, financial, and employment information. PII is often...
The reliability of today's evermore complex production systems gains in importance for competitive business environments. Failures and downtimes of machines lead to production losses and related high costs. Hence, effective and efficient maintenance is regarded as a strategic competitive advantage. In order to ensure the availability of spare parts and maintenance personnel while operating at reasonable...
Coordination of health services is one of the defining challenges of today’s healthcare system. The U.S. healthcare system has grown highly complex due to: a high pace of advances in science and technology; increasing expectations from patients who are more informed and better connected than ever; higher complexity of U.S. laws, regulations, and payment; and an increase in chronic illness [1]. Half...
With the rise of adolescent smart phone use, concerns about teen online safety are also on the rise. A number of parental control apps are available for mobile devices but adoption of these apps has been markedly low. To address this problem, I have already conducted a structured, qualitative feature analysis of 75 Android mobile apps designed for the purpose of promoting adolescent online safety...
Cloud computation has become prominent with seemingly unlimited amount of storage and computation available to users. Yet, security is a major issue that hampers the growth of cloud. In this research we investigate a collaborative Intrusion Detection System (IDS) based on the ensemble learning method. It uses weak classifiers, and allows the use of untapped resources of cloud to detect various types...
A key collaboration challenge is making complex ecosystems composed of robots, agents, and humans function together to achieve an overarching task. To do this requires both teamwork and mutual understanding between humans and software agents. As these systems scale up in size, effective data analytics and network science become critical towards understanding and guiding systems operation. My premise...
The Internet of Things holds huge promises to enhance collaboration in multiple application domains. By bringing Internet connectivity to everyday objects and environments it promotes ubiquitous access to information and integration with third-party systems. Further, connected things can be used as physical interfaces to enable users to cooperate leveraging multiple devices via parallel and distributed...
The sophistication of novel strains of polymorphic viruses, such as Stuxnet, has increased over the last decade. Traditional tools such as anti-virus, firewalls, intrusion detection/prevention systems, etc. may be incapable of detecting such strains. As a result, new methods need to be introduced in order to detect this family of malware. Combining dynamic malware analysis techniques with machine...
Crowdsensing is a powerful approach to collaboratively build representations of specific aspects of reality which are of great interest for people with special needs. In this paper, we present an evolution of the classical, vertical approach to detect urban barriers and other features to later exploit this knowledge in accessible route planning. By exposing every single part of the process as a microservice,...
Evaluating collaborative information seeking can be challenging, often more than individual information seeking. This can be attributed to the complexity of the interaction as the study involves a number of users using the systems. While this is particularly important, but rather hard when the users employ different modalities accessing the systems. In this paper, we describe a semi-structured combination...
The lifetime of a sensor network is very important, especially in data-intensive applications, such as military monitoring, the internet of things, and audio/video surveillance, since battery capacity is always limited. Accordingly, the deployments of relay nodes and the configuration of mobile relays in sensor networks have been extensively investigated. Since mobile relays support movement, the...
The Information Retrieval in the World Wide Web (Web IR) plays an important role in the use of the Internet. An information retrieval process begins when a user enters a formal statements of information needs, known as query, into the system and ends when results are given. Results consist of several objects that match the query with different degrees of relevancy. The relevancy of the results is...
This paper investigates the consensus control problem of the train dynamical system consisting of a large number of vehicles, where the train system traction operation based on optimal switched hierarchical LQR is involved. Based on the hierarchical structure, the train dynamical system is constructed as a two-layer hierarchical network with the aid of regrouping methodology. The lower layer utilizes...
Collaboration between robots and humans means different things to different people in different applications. Collaboration could range from a robot and a human simply operating in the same area, to operations that require complex, interdependent decisions based on joint goals. Despite the level of coordination, all effective collaborations require understanding the control allocation processes, and...
Interaction and visualization are two significant methods for both business people and scientists to find “gold nuggets” buried in raw data. These two methods can simplify complex theories and make it easier for people from different research areas to cooperate. Many prevalent web-based data interaction and visualization tools and libraries are not as effective as before because of big data. Most...
Assisting teams of knowledge workers achieve common strategic and tactical goals is becoming an increasing priority as information analysis tasks become more complex. Tools to monitor and support individual workers, such as TaskTracer, demonstrated the potential for assisting individuals but there is a lack of tools for analyzing workflows and information needs at a collaborative level within enterprises...
Minimizing the impact of network convergence events has been an active area of research and innovation since it usually occurs unexpectedly and triggers (often jolting) alarms in network operations centers. Examination of router logs, network management system information, and router configuration reviews are the standard tools for assessment and often do not lead to satisfactory conclusions. We introduce...
In this paper we describe the design and validation of a virtual fitness environment aiming at keeping older adults physically and socially active. We target particularly older adults who are socially more isolated, physically less active, and with less chances of training in a gym. The virtual fitness environment, namely Gymcentral, was designed to enable and motivate older adults to follow personalised...
