Estimating the Energy Consumption in Pervasive Java-Based Systems
Authors: Chiyoung Seo, Sam Malek, Nenad Medvidovic
Venue: Proceedings of the 2008 Sixth Annual IEEE International Conference on Pervasive Computing and Communications (2008)

We define and evaluate a framework for estimating the energy consumption of pervasive Java-based software systems. The framework’s primary objective is to enable an engineer to make informed decisions when adapting a system’s architecture, such that the energy consumption on hardware devices with a finite battery life is reduced, and the lifetime of the system’s key software services increases. Our framework explicitly takes a component-based perspective, which renders it well suited for a large class of today’s distributed, embedded, and pervasive applications. The framework provides a novel approach that facilitates the accurate estimation of a system’s energy consumption both during system construction-time and during runtime. In a large number of distributed application scenarios, the framework showed very good precision on the whole, giving results that were within 5% of the actually measured power losses incurred by executing the software.

There seems to be a general consensus on the crucial role metadata can play for enhancing the functionalities of scientific workflows systems, e.g., workflow and service discovery, composition and provenance browsing, among others. However, in most cases their management is underspecified, if not left unaddressed at all. A step in this direction, the main contribution of the work presented in this paper is an overview of metadata and their management in the Taverna workflow system. In Taverna, we consider metadata to be a first class citizen in the system, in the sense that we fully cover their life cycle from their creation, through their use and curation until their eventual removal. We present the main steps of this cycle and present the models used for metadata specification. In doing so, we distinguish two classes of metadata: metadata that describe workflow related entities, such as services, workflows and sub-workflows, and metadata that describe workflow executions, also known as workflow provenance.
Algorithms and Methods beyond the IEEE 802.15.4 Standard for a Wireless Home Network Design and Implementation
Authors: M. A. Lopez-Gomez, A. Florez-Lara, J. M. Jimenez-Plaza, J. C. Tejero-Calado
Venue: Proceedings of the 2008 IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing (sutc 2008) (2008)

The aim of this paper is to describe techniques and algorithms that have been used to design and implement a commercial wireless home network (WHN). Although IEEE 802.15.4 supposes an efficient solution for the lower layers of the communication stack, several key issues are out of its scope. Topology control (TC) of the network, address management, and multi-hop synchronization are some of these issues, which are covered in this paper. The WHN has been designed taking in mind low complexity, low consumption, and low end-to-end latency. These objectives have been reached thanks to a multi-hop beaconed structure, a distributed address management, and a routing algorithm based on masks.
New algebraic design for better P2P Features (abstract only)
Authors: Osman Guzide, Kenneth May, James Getz, Adam Edgeson
Venue: ACM Communications in Computer Algebra (2008)

Lately P2P application routing got interest and finding better routing and increasing performance and security is real challenge these days. Mostly research use overlay routing even using interconnection network design dynamically. Goal is to route a message to a destination whose IP address is not known which eliminates the need for large routing tables. Nevertheless, the overlay network could become wasteful because outgoing traffic may take a route longer than necessary. In this abstract, we propose a new design for P2P features. These new design is to combine physical and logical networks to reduce traffic and improving performance and security. This new design provides node organization for faster searching. Work used simulation program to show these new design better performance than existing design. Algorithm of new routing is defined mathematical algebraic model to show every case. Our next step is to actually improving localizing design with new overlay network design.
SystemClick: a domain-specific framework for early exploration using functional performance models
Authors: Christian Sauer, Matthias Gries, Hans-Peter Löb
Venue: Proceedings of the 45th annual Design Automation Conference (2008)

A wireless network (WLAN) provides unique challenges to system design. A WLAN uses a shared and highly unreliable medium, where protocols must rely on precise timing of requests and responses to detect submission errors and priorities among network nodes. In addition, WLAN stations are often embedded and have tight constraints on power, costs, and performance. To design WLAN nodes, precise estimations on performance and resource usage are needed for the complete network system to explore the design space and assess the quality of solutions. Our SystemClick framework combines SystemC with resource models and performance annotations derived from actual implementations based on Click. Model generation is automated, and the performance of a SystemClick model is obtained depending on actual activation patterns of different functional blocks in the model. A 802.11 a/b/g/e case study demonstrates our approach for the analysis of real-time critical systems.
DNA algorithms for fractal construction-an application of the SInsDelP system
Authors: A. Murugan, K. S. Easwarakumar
Venue: International Journal of Computer Mathematics (2007)

The SInsDelP system with single contextual insertion and (u, v)-contextual deletion was introduced by Murugan and Easwarakumar. In this paper we discuss an application of the SInsDelP system for the construction of fractal images. The fractal images considered are of self-similar types, such as Koch Snowflake, Anti-Koch Snowflake, Fractal Tree and Sierpinski Triangle. This is performed in two stages. A DNA sequence for the fractal image is generated first by a sequence of SInsDelP operations, and then the respective image is produced through the specialized recognition algorithm.

Authors: Darmesah Gabda, Noraini Abdullah, Kamsia Budin, C. K. Lim
Venue: Proceedings of the 2nd WSEAS International Conference on Computer Engineering and Applications (2008)

The objective of this study was to determine the association between the number of asthmatic patients in Kota Kinabalu, Sabah with the air quality and meteorological factors using multiple linear regression. The main eight independent variables with the fourth order interactions were included in the model. There were 80 possible models considered and the best model was obtained using the eight selection criteria (8SC). The result showed that the best model would represent the cause of the rise in the number of asthmatics modeled by M80. 23.
Creating a cognitive metric of programming task difficulty
Authors: Brian de Alwis, Gail C. Murphy, Shawn Minto
Venue: Proceedings of the 2008 international workshop on Cooperative and human aspects of software engineering (2008)

Conducting controlled experiments about programming activities often requires the use of multiple tasks of similar difficulty. In previously reported work about a controlled experiment investigating software exploration tools, we tried to select two change tasks of equivalent difficulty to be performed on a medium-sized code base. Despite careful effort in the selection and confirmation from our pilot subjects finding the two tasks to be of equivalent difficulty, the data from the experiment suggest the subjects found one of the tasks more difficult than the other. In this paper, we report on early work to create a metric to estimate the cognitive difficulty for a software change task. Such a metric would help in comparing between studies of different tools, and in designing future studies. Our particular approach uses a graph-theoretic statistic to measure the complexity of the task solution by the connectedness of the solution elements. The metric predicts the perceived difficulty for the tasks of our experiment, but fails to predict the perceived difficulty for other tasks to a small program. We discuss these differences and suggest future approaches.
Cryptanalysis of Wang et al.'s Remote User Authentication Scheme Using Smart Cards
Authors: Eun-Jun Yoon, Eun-Jung Lee, Kee-Young Yoo
Venue: Proceedings of the Fifth International Conference on Information Technology: New Generations (2008)

In 2004, both Ku et al. and Yoon et al. proposed remote user authentication scheme using smart cards, respectively. In 2007, Wang et al., however, showed that both Ku et al.'s scheme and Yoon et al.'s scheme are vulnerable to guessing attacks, forgery attacks and denied serviceattacks, as well as inefficiency in password authentication. Then, Wang et al. proposed an improvement on them to keep the merits of original schemes by using two-variant hashing operations. Nevertheless, this paper shows that Wang et al.'s scheme still does not provide perfect forward secrecy and is susceptible to a guessing attack and Denning-Sacco attack.
A New Approach of Fuzzy-Clustered Channel Assignment Method Promoting Hierarchical Cellular Network Performance
Authors: Kenvi Wang, Tong-Tai Chiang, Lin-Yi Peng, M. Merabti
Venue: Proceedings of the 22nd International Conference on Advanced Information Networking and Applications - Workshops (2008)

Fuzzy-based technology is an important topic and widely used in routing computing and channel assignment of wireless network for recent years. But some of related technologies unfortunately existed are always too complicated, costly routing searching procedures and not real applied. A new idea using a fuzzy-clustered route searching & channel assignment approach is proposed in this article to improve this problem. Furthermore, a case study and simple system implementation is demonstrated to verify the technique we propose.
An Improved Condensing Algorithm

Venue: Proceedings of the Seventh IEEE/ACIS International Conference on Computer and Information Science (icis 2008) (2008)

kNN classifier is widely used in text categorization, however, kNN has the large computational and store requirements, and its performance also suffers from uneven distribution of training data. Usually, condensing technique is resorted to reducing the noises of training data and decreasing the cost of time and space. Traditional condensing technique picks up samples in a random manner when initialization. Though random sampling is one means to reduce outliers, the extremely stochastic may lead to bad performance sometimes, that is, advantages of sampling may be suppressed. To avoid such a misfortune, we propose a variation of traditional condensing technique. Experiment results illustrate this strategy can solve above problems effectively.
Guarantee of service (GoS) support over MPLS using active techniques
Authors: A. M. Dominguez-Dorado, F. J. Rodríguez-Pérez, J. L. González-Sánchez
Venue: Proceedings of the 4th WSEAS International Conference on Applied Informatics and Communications (2004)

MPLS (Multiprotocol Label Switching) technology provides powerful mechanisms to integrate network technologies like ATM and IP with Quality of Service. Although this technology is becoming mature, there are still some aspects to be solved, such as offering guaranteed services to privileged sources that can require GoS (Guarantee of Service). To do so, on the one hand a mechanism of local recovering or packets retransmission requiring Guarantee of Service is analysed; on the other hand the implementation of a local LSP recovering system is studied.
In Silico Drug Screening Based on a Protein-Compound Affinity Matrix
Authors: Yoshifumi Fukunishi
Venue: Proceedings of the 2008 International Conference on Biocomputation, Bioinformatics, and Biomedical Technologies (2008)

We developed a new method to improve the accuracy of molecular interaction data using a protein-compound affinity matrix calculated by protein-compound docking software. We approximated the protein-compound binding free energy as a linear combination of the raw docking scores of the compound with many different proteins. The coefficients of the linear combination were estimated based on the amino-acid sequence similarities among proteins. This method was applied to in silico screening of the active compounds of five target proteins using multiple target screening, and it increased the hit ratio by several times compared to that given by the raw docking scores. The hit ratio also becomes robust against the difference of target proteins. In addition, we have developed some methods based on a protein-compound affinity matrix. When some active compounds were known, a consensus score, which combines the structure-based and ligand-based screening results, was applied to a target. Finally, we could achieve a high hit ratio for some targets by using a combination of screening methods.
Computer forensics workshop for undergraduate students
Authors: Derek Bem, Ewa Huebner
Venue: Proceedings of the tenth conference on Australasian computing education - Volume 78 (2008)

This paper describes our experience in the design and implementation of a computer forensics specialisation for the Bachelor of Computer Science degree and its capstone subject Computer Forensics Workshop. Our motivation for introducing this specialisation was to respond to the growing demand for professional services in computer forensics by the government and industry as well as to attract undergraduate students back to computing. Computer forensics is an emerging multidisciplinary field with foundations in computer science and law, and academically it is best positioned as a stream in general computer science degrees. The capstone subject in the specialisation, Computer Forensics Workshop, is practically oriented with a substantial laboratory component. The subject is taught by a team of academics, each contributing their expert knowledge in operating systems, file systems, network security and cryptography. The aim is to prepare the students to enter the job market as a professional computer forensics specialist, either in a law enforcement agency or a business organisation relying on computer information systems.

An Efficient Clustering Scheme to Exploit Hierarchical Data in Network Traffic Analysis
Authors: Abdun Naser Mahmood, Christopher Leckie, Parampalli Udaya
Venue: IEEE Transactions on Knowledge and Data Engineering (2008)

There is significant interest in the data mining and network management communities about the need to improve existing techniques for clustering multi-variate network traffic flow records so that we can quickly infer underlying traffic patterns. In this paper we investigate the use of clustering techniques to identify interesting traffic patterns from network traffic data in an efficient manner. We develop a framework to deal with mixed type attributes including numerical, categorical and hierarchical attributes for a one-pass hierarchical clustering algorithm. We demonstrate the improved accuracy and efficiency of our approach in comparison to previous work on clustering network traffic.
An effective error-resilient coding for H.264 video
Authors: Yuk Ying Chung, Leo Li Fan Chen, Zeng Zheng, Xiaoming Chen
Venue: Proceedings of the 5th WSEAS International Conference on Circuits, Systems, Electronics, Control & Signal Processing (2006)

The transmission errors in H.264 may propagate in the temporal direction. Errors in intra-coded picture (I-frame) will propagate into the associated P-B frame if they are in the same Group Of Picture (GOP). Therefore it is important to detect errors in the I-frame rather than in the P-B frame. This paper proposes and demonstrates an effective technique of Error-Resilient Coding based on bit-error detection and Directional Intra-Frame Concealment (DIFC) for H.264 video. The bit error detection is derived from multiblock checksum, chain coverage and remainder coding. DIFC takes advantage of flexible block sizes to deal with detailed movement areas and employs object edge detection to improve the accuracy of spatial interpolation. The results showed that the proposed directional intra-frame concealment has a better performance than the weighted pixel interpolation in H.264 software.
Suppression of bounded exogenous disturbances: Output feedback
Authors: B. T. Polyak, M. V. Topunov
Venue: Automation and Remote Control (2008)

The paper was devoted to rejection of bounded exogenous disturbances and considered design of the static output feedback minimizing the invariant ellipsoids of the dynamic system. The problems of control analysis and design come to the equivalent conditions in the form of linear matrix inequalities and to the problem of semidefinite programming. The state estimate obtained using the Luenberger observer was used at that.
Three-dimensional SU-8 sub-micrometer structuring by electron beam lithography
Authors: Daniel M. Koller, Andreas Hohenau, Harald Ditlbacher, Nicole Galler, Anne-Laure Baudrion, Frank Reil, Stefan Schausberger, Franz R. Aussenegg, Alfred Leitner, Joachim R. Krenn
Venue: Microelectronic Engineering (2008)

We demonstrate electron beam lithography on the negative tone electron resist SU-8 to fabricate self-supporting three-dimensional structures in sub-micrometer range. Applying SU-8 thin films spin cast on glass substrates and forming layers of 1@mm thickness, the structuring is performed in a two step process. First, the SU-8 film is exposed for supporting structures down to the substrate, a second exposure step with accordingly modified parameters leads to elevated structures. Applications as microscale shadow masks for evaporation based deposition processes and microfluidics are discussed.
Personal financial planning based on fuzzy multiple objective programming
Authors: Chieh-Yow ChiangLin, Chang-Chun Lin
Venue: Expert Systems with Applications: An International Journal (2008)

Personal financial planning involves managing all the money activities during a planner's lifetime. Traditional personal financial planning procedures begin with the planner's financial status, goals, and expectations for the future before future cash flows of different time periods under various scenarios can be determined. If the planning results fail to meet the planner's expectation, the planner adjusts tunable parameters repeatedly until an acceptable financial arrangement can be obtained. Such a ''trial-and-error approach'' or ''what-if analysis'' does not promise to achieve the optimal plan while numerous outcomes burden the planner. Multiple objectives with different goals of different importance levels might be involved in this decision-making problem. Since the objectives tend to conflict with each other, this study proposes to solve the problem based on a decision model that incorporates a fuzzy multiple objective programming method to achieve better solutions than using ''trial-and-error''.
Pacemakers and Implantable Cardiac Defibrillators: Software Radio Attacks and Zero-Power Defenses
Authors: Daniel Halperin, Thomas S. Heydt-Benjamin, Benjamin Ransford, Shane S. Clark, Benessa Defend, Will Morgan, Kevin Fu, Tadayoshi Kohno, William H. Maisel
Venue: Proceedings of the 2008 IEEE Symposium on Security and Privacy (2008)

Our study analyzes the security and privacy properties of an implantable cardioverter defibrillator (ICD). Introduced to the U.S. market in 2003, this model of ICD includes pacemaker technologyand is designed to communicate wirelessly with a nearby external programmer in the 175 kHz frequency range. After partially reverse-engineering the ICD's communications protocol with an oscilloscope and a software radio, we implemented several software radio-based attacks that could compromise patient safety and patient privacy. Motivated by our desire to improve patient safety, and mindful of conventional trade-offs between security and power consumption for resource-constrained devices, we introduce three new zero-power defenses based on RF power harvesting. Two of these defenses are human-centric, bringing patients into the loop with respect to the security and privacy of their implantable medical devices (IMDs). Our contributions provide a scientific baseline for understanding the potential security and privacy risks of current and future IMDs, and introduce human-perceptible and zero-power mitigation techniques that address those risks. To the best of our knowledge, this paper is the first in our community to use general-purpose software radios to analyze and attack previously unknown radio communications protocols.
Enabling verification and conformance testing for access control model
Authors: Hongxin Hu, GailJoon Ahn
Venue: Proceedings of the 13th ACM symposium on Access control models and technologies (2008)

Verification and testing are the important step for software assurance. However, such crucial and yet challenging tasks have not been widely adopted in building access control systems. In this paper we propose a methodology to support automatic analysis and conformance testing for access control systems, integrating those features to Assurance Management Framework (AMF). Our methodology attempts to verify formal specifications of a role-based access control model and corresponding policies with selected security properties. Also, we systematically articulate testing cases from formal specifications and validate conformance to the system design and implementation using those cases. In addition, we demonstrate feasibility and effectiveness of our methodology using SAT and Alloy toolset.
Development of a New Software Product from a Classroom Project
Authors: Jeremy W. Pauli, Ty E. Lawrence, Brennon F. Brown
Venue: Proceedings of the Fifth International Conference on Information Technology: New Generations (2008)

It has long been known that the campus is fertile grounds for IT entrepreneurship through the identification and nurturing of possible commercial software systems[1], [2]. The campus is uniquely suited in many ways because failed ventures can still be considered worthwhile due to the knowledge gained and disseminated through the very process of creating a new system. Moving a project from idea to class project to retail ready system is a method for identifying and producing systems that both educate and become viable retail systems. Most examples tend to be small to medium size projects that fit a general need or are unique in implementation in some way. Our project produced a rewarding educational experience for the students and a new piece of software for market.
