Cyber-physical systems are tight integrations of computation, networking, and physical objects. Advances recently witnessed in pervasive and ubiquitous information processing, driven by major breakthroughs in cyber-physical technology are paving the way towards a more hospitable and sustainable future via a more efficient management of our environment: homes, work places, open areas, etc. Examples...
To date, several methods and tools for detecting source code and design anomalies have been developed. While each method focuses on identifying certain classes of source code anomalies that potentially relate to technical debt (TD), the overlaps and gaps among these classes and TD have not been rigorously demonstrated. We propose to construct a seminal technical debt landscape as a way to visualize...
Underwater acoustic channel imposes many challenges into underwater networks communication, such as high bit error, temporary losses of connectivity due to shadow zones, limited bandwidth capacity and communication signal spreading over large areas. Opportunistic routing is a new routing paradigm that allows more than one node to forward a packet by taking advantage of the broadcast medium and overhearing...
Breast cancer detection with infrared imaging is a technique that is hazardous radiation free, increases the early detection chance and has a high detection probability. Asymmetry analysis is used for the diagnosis and the analysis is done using the breast segments obtained from the infrared image. In this work, a breast segmentation system based on parabolic Hough transform is presented. Besides,...
In the petascale era, the storage stack used by the extreme scale high performance computing community is fairly homogeneous across sites. On the compute edge of the stack, file system clients or IO forwarding services direct IO over an interconnect network to a relatively small set of IO nodes. These nodes forward the requests over a secondary storage network to a spindle-based parallel file system...
With the ubiquitous nature and sheer scale of data collection, the problem of data summarization is most critical for effective data management. Classical matrix decomposition techniques have often been used for this purpose, and have been the subject of much study. In recent years, several other forms of decomposition, including Boolean Matrix Decomposition have become of significant practical interest...
The SEARIS (Software engineering and architectures for realtime interactive systems) workshop at IEEE Virtual Reality is five years old, which presents an opportunity for reflection. Papers were gathered in advance that were considered central to SEARIS. Audience members presented and then all discussed each paper, leading to frank discussions and firsthand stories. An analysis of these discussions...
Following the definition of finite time stability, corresponding fundamental theories are given, including qualitative conclusion and application area results regarding finite time stabilization controller design. A detailed description of a class of nonlinear systems is provided. Modeling and linearization problem of single inverted pendulum system are considered. Finally, with the help of linear...
Steganalysis is the science of detecting the presence of hidden information in media files. In this paper, we propose a simple scheme based on close colours that detects not only the presence of hidden information but also the size of the hidden information. The scheme applies to synthetic digital images with a small number of distinct colours (such as logos and flags). We compare our scheme to another...
Teamwork has become a widely accepted metaphor for describing the nature of multi-robot and multi-agent cooperation. By virtue of teamwork models, team members attempt to manage general responsibilities and commitments to each other in a coherent fashion that both enhances performance and facilitates recovery when unanticipated problems arise. Whereas early research on teamwork focused mainly on interaction...
Every year, tens of thousands of middle school and high school students participate in robotics competitions, such as Botball, FIRST, and VEX. This provides them with an excellent introduction to the ins and outs of building robots and programming them to autonomously accomplish specific tasks. However, the rules of many of these competitions often limit or prohibit human interaction with the robots...
This paper describes a non-intrusive eyetracking tool for mobile devices by using images acquired by the front camera of the iPhone and iPod Touch. By tracking and interpreting the user's gaze to the smartphone's screen coordinates the user can interact with the device by using a more natural and spotaneous way. The application uses a Haar classifier based detection module for identifying the eyes...
The application of Multi-Agent Systems (MAS) in electrical power systems are becoming popular due to their inherent benefits such as increased autonomy, reactivity, proactivity and social ability. This paper reviews current research on the application of multi-agent systems in microgrid schemes. The paper is mainly focused on recent developments of multi-agent systems in different aspects of microgrids...
With ever-developing sequencing technologies, gaps between sequence mapping research work and commercial applications in clinical scenario are narrowing. However, the storage problem of alignment results is still a big challenge remained. From both storage and application perspectives, traditional approaches in alignments output files still leave much to be desired. In this paper, we try to explore...
General purpose processors provide a well performance with adequate power consumption for a huge bandwidth of applications in average. However, most embedded systems target a very narrow or even single application domain which would benefit from a specific processor, optimized for this scenario in order to gain performance and to reduce power consumption. But the development of application specific...
