Annual IEEE Symposium on computer-Based Medical systems

作者： Sandi Pohorec Mateja Verlic Milan Zorman Laboratory of system design Faculty of electrical engineering and computer science University of Maribor Slovenia

We present the results of a data mining research on the use of GPS positions and speed of travel of vehicles in urban areas to determine optimal travel routes for emergency vehicles. A new approach using predictive programming is presented. The approach focuses on using data mining of existing data as the key factor in the application logic where various decisions are to be made. The main appeal of such an approach is that the application logic evolves over time according to the application data. As the data changes the decisions soon follow. This gives the impression of intelligent behavior of the application.

With our society more information-driven, we have begun to distribute data in wide-area storage systems. At the same time, both physical failure and logic error have made it difficult to bring the necessary recovery to bear on remote data disaster, and understanding this proceeding. We describe ARRAY, a system architecture for data disaster recovery that combines reliability, storage space, and security to improve performance for data recovery applications. The paper presents an exhaustive analysis of the design space of ARRAY systems, focusing on the trade-offs between reliability, storage space, security, and performance that ARRAY must make. We present RSRAII (Replication-based Snapshot Redundant Array of Independent Imagefiles) which is a configurable RAIDlike data erasure-coding, and also others benefits come from consolidation both erasure-coding and replication strategies. A novel algorithm is proposed to improve snapshot performance referred to as SMPDP (Snapshot based on Multi-Parallel Degree Pipeline).

Microdevices have recently been developed by various micromachining technologies such as laser cutting, lithography, etc. PTFE is widely used as a microwave and millimeter-wave material. However, it is known that PTFE is too difficult to process with high precision by conventional machining, or even by laser cutting or electrical discharge machining. It has been reported that PTFE microstructures can be fabricated by direct exposure to synchrotron radiation. In this paper, the SR direct etching of PTFE is introduced and a trial fabrication of millimeter-wave PTFE-filled waveguide by sputter deposition of metal is attempted. © 2009 The Institute of Electrical Engineers of Japan.

Local search engine with global content based on domain specific knowledge

WSEAS Transactions on Information science and Applications 2009年第9期6卷 1544-1554页

In the growing need for information we have come to rely on search engines. The use of large scale search engines, such as Google, is as common as surfing the World Wide Web. We are impressed with the capabilities of these search engines but still there is a need for improvment. A common problem with searching is the ambiguity of words. Their meaning often depends on the context in which they are used or varies across specific domains. To resolve this we propose a domain specific search engine that is globally oriented. We intend to provide content classification according to the target domain concepts, access to privileged information, personalization and custom ranking functions. Domain specific concepts have been formalized in the form of ontology. The paper describes our approach to a centralized search service for domain specific content. The approach uses automated indexing for various content sources that can be found in the form of a relational database, web service, web portal or page, various document formats and other structured or unstructured data. The gathered data is tagged with various approaches and classified against the domain classification. The indexed data is accessible through a highly optimized and personalized search service.

Event log is the important starting point of any process analysis technique. Existent business process analysis techniques are applied mainly to manual or simulated logs, considering mainly information about control perspective. In this paper, we first analyze the feature of data perspective of PLM (Product Lifecycle Management) system in manufacturing area, and extend the MXML format to support the log with data perspective information in PLM domain. Subsequently, we introduce an approach of data cleaning to separate the multi-version process information in real-life data set. In the end, we produce real-life log with information about data perspective in PLM system, then, mine the process model from real-life log and evaluate the proposed approach by fitness measuring. © 2008 IEEE.

A 1.3 pJ/b inductive coupling transceiver is proposed for Cm-range multimedia data transmission in mobile device applications. Its transmission time control (TTC) scheme and adaptive gain control (AGC) scheme reduce the energy consumption below to 1.3 pJ/b. Inductor with self-resonance frequency above 200 MHz achieves the data rate over 50 Mbps. The receiver sensitivity can be enhanced to increase the communication distance up to 7 cm by relative magnitude comparison between two nodes of the receiver inductor. The transceiver consumes only 65 ¿W in total with 1 V supply.

A cumulant-based method for gait identification using accelerometer data with principal component analysis and support vector machine

引用

WSEAS Transactions on Signal Processing 2009年第11期5卷 369-378页

In this paper a cumulant-based method for identification of gait using accelerometer data is presented. Acceleration data of three different walking speeds (slow, normal and fast) for each subject was acquired by the accelerometer embedded in cell phone which was attached to the person's hip. Data analysis was based on gait cycles that were detected first. Cumulants of order from 1 to 4 with different number of lags were calculated. Feature vectors for classification were built using dimension reduction on calculated cumulants by principal component analysis (PCA). The classification was accomplished by support vector machines (SVM) with radial basis kernel. According to portion of variance covered in the calculated principal components, different lengths of feature vectors were tested. Six healthy young subjects participated in the experiment. The average person recognition rate based on gait classification was 90.3±3.2%. A similarity measure for discerning different walking types of the same subject was also introduced using dimension reduction on accelerometer data by PCA.

Survivability has become a focal point of research. Simulation is a common method for experimental verification to identify the advantages and deficiencies of survivability models and architectures. This paper proposes a modeling approach of mobile ad hoc network survivability model which support the automatic transformation to a simulation instance. A new survivability model MARC based on the idea of ARC model is conducted. Within this model, the concepts of network services and events are analyzed and formally descript in details. Base on these works, we design MARCDL and outline the important EBNF in this paper. Use of this language is illustrated by a case study. ©2009 IEEE.

Effective treatment of chronic radiation proctitis using radiofrequency ablation

Endoscopic argon plasma coagulation and bipolar electrocautery are currently preferred treatments for chronic radiation proctitis, but ulcerations and strictures frequently occur. Radiofrequency ablation (RFA) has been successful for mucosal ablation in the esophagus. Here we report the efficacy of RFA with the BarRx Halo⁹⁰ system in three patients with bleeding from chronic radiation proctitis. In all cases, the procedure was well tolerated and hemostasis was achieved after 1 or 2 RFA sessions. Re-epithelialization of squamous mucosa was observed over areas of prior hemorrhage. No stricturing or ulceration was seen on follow-up up to 19 months after RFA treatment. Real-time endoscopic optical coherence tomography (EOCT) visualized epithelialization and subsurface tissue microvasculature pre- and post-treatment, demonstrating its potential for follow-up assessment of endoscopic therapies. © 2009, SAGE Publications.
