In smart environments, the extraction of relevant information in large volumes of data collected from intelligent devices is a crucial issue. The extracted information can assist in automation of user activities and on daily chores, either suggesting or even changing the state of devices based on his/her routine. In this work, we propose a prediction architecture which combines an innovative preprocessing...
Traditional graph based sentence ranking approaches modeled the documents as a text graph where vertices represent sentences and edges represent pairwise similarity relationships between two sentences. Such modeling cannot capture complex group relationships shared among multiple sentences which can be useful for sentence ranking. In this paper, we propose two different group relationships (sentence-topic...
One of the key activities needed to construct a quality service-oriented solution is specification of the architectural elements. Selection of an appropriate and proven method for specification of the elements consisted of services, flows, and components is thus fundamental to successful service-oriented system development in an enterprise. Existing methods for service specification ignore the automation...
Continuous blood pressure (BP) measurement based on pulse wave velocity (PWV) requires acquiring two pulse waves from different locations of human body. Choosing suitable and effective pulse transducers is critical for measuring PWV accurately and stably. In this paper, ultrasonic transducer, strain transducer, bio-electric resistance transducer and infrared light transducer are chosen as the objects...
The research of network test grows rapidly with the development of network technology. People need more flexible network test and platform to estimate their network equipment, and the scholars need more flexible mathematics model to describe and generate the network traffic or test traffic. In this paper, we introduce a GI/G/m/??/FCFS multi-class open queuing network model for generating stochastic...
To complete parallel test for airplane Remote Electronics Unit (REU), the initial problem which should be resolved is the resources allocation. Optimized configuration of test resources will contribute to smoothing the implementation of task scheduling, which in turn improves the efficiency of the test. Close analysis of constraint relations between resources and test tasks, and with global heuristic...
Biomimetic robots have recently received increasing attention, as people try to learn from nature in which exist amazing and uniquely evolved mechanisms shown by very species. Fleas, as such one example, are best jumper of all known animals in the world, considering their body size. It can jump about 150 to 200 times its own body length. This paper reports on modeling and simulation of a jumping biomimetic...
Sailing vessels such as sailboats but also landyachts are vehicles representing a real challenge for automation. However, the control aspects of such vehicles were hitherto very little studied. This paper presents a simplified dynamic model of a so-called landyacht allowing to capture the main elements of the behavior of surface sailing vessels. We then propose a path generation scheme and a controller...
Abstract-Large-scale enterprises need their software systems to deal with massive extremely important heterologous and heterogeneous data, which makes the quality assurance to them also very critical, and this also made an enormous challenge to QA staffs. To automate this process as far as possible is the key factor to ensure that terrifically useful information is effective and the validating is...
The evolution of the IEEE Robotics and Automation (RAS) is described, including the process of organizing a new IEEE society and significant events and individuals in the history of RAS.
This paper presents an ontology for performance that is also the basis for an enterprise modeling and measurement framework for managing complex systems through improved traceability. The treaceability is achieved in the context of hand-offs that are typical of discovery in service-oriented environments. Examples in the health care industry illustrate the value of traceability in highly dynamic information...
Chernoff face is a technique of multidimensional data visualization in multivariate statistics. This paper proposes a new method to quantify the overall features of Chernoff faces, and presents a new programmed method for clustering Chernoff faces. Using this method misjudgment caused by human eyes can be avoided. Moreover, people can further evaluate the samples if the evaluation standard is given...
The desire for a high mobility-to-size ratio in mobile robots has led to the exploration of many new methods of locomotion, one of which is tumbling. We believe that tumbling has a great potential to produce high mobility-to-size ratios in miniature mobile robots. In this paper we discuss tumbling locomotion and introduce the Adelopod, a small two-armed tumbling robot recently developed at the University...
Metal spinning is a plastic forming process in which a relatively ductile metal sheet is forced onto a rotataing mandrel by using a roller tool. This study is aimed at developing a versatile and intelligent forming process and expand the application area of robotic manufacturing processes. In this research, the metal spinning process has been accomplished with an industrial robot. Trajectory control...
Suddenly fall of unexpected disasters cause serious damage and casualties to our society. In order to minimize damage, search and rescue tasks should be carried out immediately after the disasters. This paper introduces an entropy based search model to RoboCup rescue agent simulation system which enables our search agents to find victims as early as possible. Key point of this proposed model lies...
In this study a strain gage load cell as a S model has been designed which is used for measuring weight of elevator. Four methods of fixing and balancing Whetstone Bridge were considered and one way was achieved eventually which was given the best Whetstone Bridge's output. For amplifying and measuring of changing resistance and voltage in Whetstone Bridge four current ways of amplifying and measuring...
A k-plex is a graph theoretic generalization of a clique, introduced in social network analysis (SNA) to model tightly knit social subgroups referred to as cohesive subgroups. Clique model was the earliest mathematical model for a cohesive subgroup, but its overly restrictive definition motivated several relaxations including the k-plex model. The models from SNA are suitable, and potentially more...
Mining closed frequent itemsets in the sliding window is one of important topics of data streams mining. In this paper, we propose a novel algorithm, FPCFI-DS, which mines closed frequent itemsets in the sliding window of data streams efficiently, and maintains the precise closed frequent itemsets in the current window at any time. The algorithm uses a single-pass lexicographical-order FP-Tree-based...
The paper, in the basis of studying the humanoid intelligent control basic model, proposed the multi-agent level hierarchical structure model, in detail introduced the control system characteristic vector extraction, the system dynamic characteristic pattern and the classified method, the characteristic pattern and the control strategy mapping relations. Then, the thesis discussed the multi-agent...
