Learning from failures in evolutionary computation @ GECCO-2009: events reports
Authors: Mike Preuss, Nicola Beume
Venue: ACM SIGEVOlution (2008)

Why should one do a workshop on failures when the primary goal of each scientific investigation is success? Looking at former and recent publications in evolutionary computation, the general impression is indeed that only success stories are told. As everybody who is experienced in experimental or theoretical research knows that failures happen, and are sometimes even necessary steps to success, the question shall be raised if reporting failures does have a positive impact on further research on a similar topic. Most researchers who gave feedback to our call agreed that it does. However, there is currently no methodology or silent consent on which failures to report and how. Furthermore, it is even unclear how much different frequently occurring failures are. As this was to our knowledge the first workshop on this topic in evolutionary computation, the most important task was thus to collect a number of cases and get an overview of the predominant types of failures.
Research on Turbidity Removal and Byproduct Magnesium Hydroxide in Alkalify Flocculation Desalination Pretreatment
Authors: Liuhe Yishouzhi, Wuyan Wujiaquan
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 01 (2009)

The reverse osmosis desalination is becoming an effective approach in seawater desalination to solve the shortage of freshwater resource. Since reverse osmosis desalination plants depend on high quality feed water to ensure. Turbidity is the most important factor of feed water of reverse osmosis desalination, and turbidity removal is a difficulty of desalination pretreatment. The alkalify flocculation desalination pretreatment technology is a cheap and effective way to reduce the turbidity of seawater. The flocculant, polyaluminiumferric chloride (PAFC), is an important additive for alkalify flocculation desalination pretreatment, and the dosage is crucial for the effect of desalination pretreatment. According to our experimental data and analysis, alkalized seawater by 9g/L lime milk, flocculated by 9ml/L PAFC and 3ml/L starch solution, turbidity reduced to 0.8NUT and meet the requirement of feed water of reverse osmosis desalination. The structure of magnesium hydroxide in floccule was regular from observed by scanning electron microscope and content improved with addition of starch from thermogravimetric analysis.

Level Mapping Induced Loop Formulas for Weight Constraint and Aggregate Programs
Authors: Guohua Liu
Venue: Proceedings of the 10th International Conference on Logic Programming and Nonmonotonic Reasoning (2009)

We improve the formulations of loop formulas for weight constraint and aggregate programs by investigating the level mapping characterization of the semantics for these programs. First, we formulate a level mapping characterization of the stable model semantics for weight constraint programs, based on which we define loop formulas for these programs. This approach makes it possible to build loop formulas for programs with arbitrary weight constraints without introducing new atoms. Secondly, we further use level mapping to characterize the semantics and propose loop formulas for aggregate programs. The main result is that for aggregate programs not involving the inequality comparison operator, the dependency graphs can be built in polynomial time. This compares to the previously known exponential time method.
Developing Java EE Applications Based on Utilizing Design Patterns
Authors: Shuang Liu, Peng Chen
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 02 (2009)

Design patterns provide an efficient way to create more flexible, elegant and ultimately reusable object-oriented software. Thus their correct application in a system’s design will significantly influence its reusability, flexibility, extensibility and maintainability. In this paper, we explain how design patterns are selected and implemented in a Java enterprise application naming Piloting management system based on a Model-View-Controller model and integration of open source frameworks such as Spring and Hibernate. Then we adopted several appropriate design patterns in the design process and validated the feasibility of this framework model in the implementation of Attemper subsystem.
View & share: supporting co-present viewing and sharing of media using personal projection
Authors: Andrew Greaves, Enrico Rukzio
Venue: Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services (2009)

Viewing and sharing media on mobile devices are popular scenarios, however, the limited screen size results in multiple users having to gather around a single display leading to an undesirable viewing experience. Similarly, sharing a single image with a single person is cumbersome and requires several steps to complete. This demonstration paper presents an approach in which a mobile phone is coupled with a personal projector to overcome the output limitations of mobile phones. The large mobile projected display allows several users to simultaneously view media. We also present a group based sharing approach allowing users to intuitively and easily share media between mobile devices. We reverse the typical role of sharing and introduce a technique whereby the receiver of the media is responsible for performing the sharing interaction. This allows sharing with a single member or multiple members of the group. Sharing with every member of the group is also easily possible.
The collaborative work of producing meaningful shots in mobile video telephony
Authors: Christian Licoppe, Julien Morel
Venue: Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services (2009)

In this paper we report on the first study of the uses of mobile video telephony based on the collection and analysis of naturally occurring mobile video telephony. We show how a characteristic feature of mobile video telephony, which makes it differ from any other kind of mediated interaction, is that: a) the participants may orient the camera at will to shoot almost any feature within their environment; and b) what they actually show at a given moment may be (and usually is) inspected by the recipient for its relevance to the ongoing interaction, and is produced with an orientation towards such scrutiny. A specific concern of mobile video call users at any time is therefore what they should or should not show. We demonstrate how a partial solution to that problem is the reliance on a particular (full) portrait-like 'talking heads' format as an expected default mode for interaction in mobile video calls. Finally, we discuss the implications, for design, of such an empirically grounded understanding of the specific practical concerns of mobile video telephony users.
Analysis on Equilibrium Point of Expectation Propagation Using Information Geometry
Authors: Hideyuki Matsui, Toshiyuki Tanaka
Venue: Advances in Neuro-Information Processing: 15th International Conference, ICONIP 2008, Auckland, New Zealand, November 25-28, 2008, Revised Selected Papers, Part II (2009)

Expectation Propagation (EP) extends belief propagation by approximating messages with expectations of statistics, in which users can choose the statistics. In this paper, we discuss how a choice of statistics affects accuracy of EP's estimates. We approximate estimation error of EP via perturbation analysis based on information geometry. By comparing the approximated estimation error, we show that adding statistics does not necessarily improve the accuracy of EP. A numerical example confirms validity of our analytical results.

An Object-Based Approach for Forest-Cover Change Detection using Multi-Temporal High-Resolution Remote Sensing Data
Authors: Jun Huang, Youchuan Wan, Shaohong Shen
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 01 (2009)

The increasing availability of remote-sensing images, acquired periodically by satellite sensors on the same geographical area, makes it extremely interesting to develop monitoring systems capable of automatically producing and regularly updating forest-cover maps of the considered site. In this paper, we designed and developed new object-based change detection algorithms, which are aimed at updating forest-cover maps by remote sensing images. The forest-cover change detection system includes several key modules: image segmentation, difference images processing and binary change detection model using threshold. These modules are evaluated by multi-temporal QuickBird remotely sensed data set: 1) In the image segmentation module, multi-scale segmentation algorithm was used to form the image objects. 2) In the difference image module, spectral value and NDVI (normalized difference vegetation index) were taken as input data. Correlation coefficient and t-test algorithms based on objects are used to develop difference images. 3) In the binary change detection module, change maps obtained from spectral value and NDVI are compared. Finally, experimental results carried out on multi-temporal QuickBird remotely sensed data set confirm the effectiveness of the proposed system.
Construction of Systematic Learning Support System of Business Theory and Method
Authors: Yoshiki Nakamura, Katsuhiro Sakamoto
Venue: Proceedings of the Symposium on Human Interface 2009 on Human Interface and the Management of Information. Information and Interaction. Part II: Held as part of HCI International 2009 (2009)

Business administration and industrial engineering expect their students to understand a lot of theories and technique and to be able to utilize their acquired knowledge in the workplace after entering business. However, the current educational system prevents these expectations from becoming a reality. The purpose of this research is designed to develop an educational simulator that teaches theories and methods and changes the effects and results generated by business decisions according to the degree of understanding. To confirm the validity, the developed simulator is tested against students to confirm its efficiency.
A Web Service Adapter with Contract-Oriented Methodology
Authors: Junhuai Li, Yile Wang, Jing Zhang, Zhuobin Zhang
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

Loose coupling is a cornerstone for Service-Oriented Architecture (SOA). Service contracts enable loose coupling, because they conceal internal details of services from the outside world behind the facade. However, current works on service oriented analysis and design (SOAD) largely focus on defining processes for developing business processes and services without considering variability in details. In this paper, a Web Service adapter of service-contract oriented is presented in order to enhance the applicability and reusability of such services. We also introduce some critical issues about service contract analysis engine, skeleton code generate engine and web-based WSDL editor in the Web Service adapter. Additionally, the Web Service adapter designed in this paper is compared with related tools, and the results indicate that our methods demonstrate a more desirable interactivity and stability.

Study on Pollution Mechanism of Petroleum Contamination in a Groundwater System under a Refinery in Jinan City
Authors: Zhang Liang, Ma Zhenmin, Li Qingguo
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

The petroleum hydrocarbon contaminant from oil industry can enter the soil and badly influence local environment. We take a groundwater system polluted by refinery’s discharged oil as research object in this paper. Firstly, we collect soil and groundwater samples in this area and perform soil column leaching experiments. The experiment results show that the pollution sources are sewage tank and canal seepage, leakage caused by production accidents, and non-point leaching of polluted soil layer and waste pits. The petroleum contaminants are mainly in three forms, i.e. emulsified oil, dissolved oil and adsorbed oil. There are three pollution mechanism including direct infiltration through limestone, infiltration through two-layer mediums, and the secondary pollution of groundwater.
Joint IP Address and Public Key Certificate Trust Model for Mobile Ad Hoc Networks
Authors: Abdelhafid Abdelmalek, Mohamed Feham, Zohra Slimane, Abdelmalik Taleb-Ahmed
Venue: Proceedings of the 8th International Conference on Ad-Hoc, Mobile and Wireless Networks (2009)

This paper focuses on the autoconfiguration security problem in MANETs. We propose a new fully distributed IPv6 autoconfiguration scheme providing both security and robustness. Our solution introduces a new trust model based on a new concept of joint IP address and public key certificate, exploiting recently published Discrete Logarithm based threshold cryptographic tools. The proposed scheme solves all limitations of earlier approaches and seems to be a perfect solution for MANETs under strong advarsarial model.
Smart Privacy Management in Ubiquitous Computing Environments
Authors: Christian Bünnig
Venue: Proceedings of the Symposium on Human Interface 2009 on Human Interface and the Management of Information. Information and Interaction. Part II: Held as part of HCI International 2009 (2009)

Privacy in ubiquitous computing environments is primarily considered as a problem of protecting personal information from unauthorized access and misuse. Additionally it can also be seen as a process of interpersonal communication where not hiding but selective disclosure of personal information is the central issue, i.e. how users can practice privacy intuitively and dynamically in computerized environments similar to the analog world. In this work we discuss the management of private information concerning interpersonal privacy implications in smart environments. Existing work mostly does not match the intuitive and dynamic aspects of privacy in context of interpersonal communication. As an alternative we suggest an ad hoc approach to privacy management which uses learning techniques for an in situ disclosure assistance and present user interaction models for this disclosure assistance.

A Drift-Reduced Hierarchical Wavelet Coding Scheme for Scalable Video Transmissions
Authors: Roya Choupani, Stephan Wong, Mehmet R. Tolun
Venue: Proceedings of the 2009 First International Conference on Advances in Multimedia (2009)

Scalable video coding allows for the capability of (partially) decoding a video bitstream when faced with communication deficiencies such as low bandwidth or loss of data resulting in lower video quality. As the encoding is usually based on perfectly reconstructed frames, such deficiencies result in differently decoded frames at the decoder than the ones used in the encoder and, therefore, leading to errors being accumulated in the decoder. This is commonly referred to as the drift error. Drift-free scalable video coding methods also suffer from the low performance problem as they do not combine the residue encoding scheme of the current standards such as MPEG-4 and H.264 with scalability characteristics. We propose a scalable video coding method which is based on the motion compensation and residue encoding methods found in current video standards combined with the scalability property of discrete wavelet transform. Our proposed method aims to reduce the drift error while preserving the compression efficiency. Our results show that the drift error has been greatly reduced when a hierarchical structure for frame encoding is introduced.
"I Love My iPhone ... But There Are Certain Things That `Niggle' Me"
Authors: Anna Haywood, Gemma Boguslawski
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part I: New Trends (2009)

Touchscreen technology is gaining sophistication, and the freedom offered by finger-based interaction has heralded a new phase in mobile phone evolution. The list of touchscreen mobiles is ever increasing as the appeal of `touch' moves beyond the realms of the early adopter or fanboy, into the imagination of the general consumer. However, despite this increasing popularity, touchscreen cannot be considered a panacea. It is important to look beyond the promise of a more direct and intuitive interface, towards the day-to-day reality. Based on our independent research, this paper explores aspects of the touchscreen user experience, offering iPhone insights as examples, before presenting key best practice guidelines to help design and evaluate finger-activated touchscreen solutions for small screen devices.

Authors: Ioannis Basdekis, Panagiotis Karampelas, Voula Doulgeraki, Constantine Stephanidis
Venue: Proceedings of the 5th International on ConferenceUniversal Access in Human-Computer Interaction. Part II: Intelligent and Ubiquitous Interaction Environments (2009)

At present, a tendency towards smaller computer sizes and at the same time increasingly inaccessible web content can be noted. Despite the worldwide recognized importance of Web accessibility, the lack of accessibility of web services has an increasingly negative impact on all users. In order to address this issue, W3C has released a recommendation on Mobile Web Best Practices, supplementary to the Web Content Accessibility Guidelines. This paper presents the design and prototype development of universally accessible networking services that fully comply with those standards. Validation and expert accessibility evaluation on the XHTML Basic prototypes present 100% compliance. The followed design process is presented in details, outlining general as well as specific issues and related solutions that may be of interest to other designers. The results will be further verified through user tests on implemented services.
Audio Compression Using a Munich and Cambridge Morlet Wavelet
Authors: Khalil Abid, Kais Ouni
Venue: Proceedings of the 2009 First International Conference on Advances in Multimedia (2009)

Most psycho-acoustic models for coding applications use a uniform (equal bandwidth) spectral decomposition as a first step to approximate the frequency selectivity of the human auditory system. However, the equal filter properties of the uniform sub-bands do not match the non uniform characteristics of cochlear filters and reduce the precision of psycho-acoustic modelling. In this paper we present a new design of a psycho-acoustic model for audio coding following the model used in the standard MPEG-1 audio layer 3. This architecture is based on appropriate wavelet packet decomposition instead of a short term Fourier transformation. Its important characteristic is to propose an analysis of the frequency bands that come closer to the critical bands of the ear. This study shows the best performance of the Morlet Munich coder.
