Authors: Abed Mourad , Ezzeddine Benaissa , Benabdelhafid Abdellatif , Grabara Janusz
Published: March 2013

The importance of cooperation in the supply chain has led scholars to suggest diverse approaches for problems in the collaboration process. Cooperation refers to the integration of different parts of an organization or different organizations in supply chain to accomplish a collective set of tasks and to achieve mutual benefits. The use of modern information technology (IT) decision support systems is fast becoming an indispensable tool for designing and managing complex supply chain systems today. This study describes a model of intelligent framework for cooperation in the supply chain environment. The aim of the paper is to demonstrate that agent technology can represent the supply chains by (a) reviewing intelligent agent applications for supply chain and (b) illustrating how a multi-agent system can provides a solution for supply chain cooperation. We review and synthesis existing applications in comparison to traditional and Internet-based technologies and critically evaluate agent technology applicability for supply chain management. This paper thus provides an intelligent framework for extended enterprise cooperation (i-SEEC) by adopting the techniques of the Semantic Web service and Multi-agents system. The proposed system can integrate different information technologies to make its behavior more intelligent and to catch more useful information from supply chain actors.
Aspects of Logistics in Biomass Supply for Energy Production
Authors: Kot Sebastian , Ślusarczyk Beata
Published: March 2013

Energy production from biomass is now a very popular trend in energy generation. These initiatives are supported by the European Union legislation and state governments. Undoubtedly, the idea of renewable energy production can be justified and promising. However, it should be considered from a wider perspective of supply chain than merely focusing on the share of renewable sources in total energy production. The economic and ecological importance of biomass use to energy generation largely depends on the logistics of biomass supply to power plants. The location of biomass sources and the organization of supply are very important stages that impact on final economic results of energy production. Furthermore, the improper choice of means of transport and process organization for managing renewable sources of energy might have a negative ecological effect. Therefore, the authors attempted to analyze the cost-related aspects of biomass supply (including the seasonal biomass price fluctuation) to the analyzed power plant and the effect of this factor on financial results of energy production.

Published: March 2013

Anyone intending to manage transportation of the future must examine current developments closely. How do goods flow? How can logistical processes be organized better with the aid of new telematic technologies and handling concepts? Strategies to manage them arise from tests under real conditions and in the laboratory. Today, the reliable and precise functioning of telematic units is just as much a part of logistics as the incorporation of environmental factors. Therefore, under the auspices of the Ministry of State Development and Transportation, Saxony-Anhalt, it led to the establishment of the Saxony-Anhalt Galileo Test Bed. The test bed is intended to support developments and innovations systematically. The goal of the Saxony-Anhalt Galileo-Test Bed is to systematically support Saxony-Anhalt´s enterprises and research organizations that are developing new localization, navigation and communication services and products for transportation (road and rail) and logistics to create new jobs in these sectors. The paper deals with the research questions which should be answered.

Authors: Nad Milan , Cicmancova Lenka
Published: March 2013

mproving of cutting process is one of the most important requirements that are expected from the machining methods in the recent years. In some machining processes, the positive effect of ultrasonic waves to improve the cutting process is used. The cutting process efficiency depends on the structure of excitation system which generates ultrasonic waves. One of the most important elements of this system is the ultrasonic waveguide. The role of waveguide is the transfer of ultrasonic vibration energy from ultrasonic transducer to the tool cutting edge interacting with the workpiece (ultrasonic assisted machining-UAM). The UAM system performance depends on well-designed ultrasonic waveguide. The most important aspects of waveguide design are a resonant frequency, amplification factor and the determination of waveguide resonant wavelength - usually integer multiple of half wavelength. The effect of geometrical parameters of stepped waveguide on dynamical properties is presented in this paper.

Published: March 2013

The friction processes as the most often physical phenomena cause many negative effects in production systems, and man try to minimize them. Coefficient of friction is one of the fundamental parameters which characterizes the process of friction between two parts, which perform mutual sliding of movement. Its measurement is realised using the experimental methods. In our experiments motion of samples is enforced motorically and various measurement sensors that monitor variables characterizing the process of friction are used. Experimentally obtained values of the coefficient of friction for the bushing aluminium - steel pairs are analysed in the paper. During the run up the value of the coefficient of friction sharply decreased from 0.8 to size 0.1 and then was stable till the end. Experimental tests were realised on the equipment Tribotestor M' 89, which was used for determination of the tribological parameters of bearing bushings. Following input variables were adjusted: the sliding speed, loading of rotanional sliding joint and duration of the test. The temperature in the contact surface of bushings and the roughness parameters (Ra, Rz) were also monitored before and after the tests.

Authors: Lin Tsai Duan , Hsu Chiun Chieh , Hsu Li Fu
Published: March 2013

The on-line Class Constrained Bin Packing problem (CCBP) is one of variant version of the Bin Packing Problem (BPP). The BPP is to find the minimum numbers of bins needed to pack a given set of items of known sizes so that they do not exceed the capacity B of each bin. In the CCBP, we are given bins of capacity B with C compartments and n items of Q different classes, each item i is belong to 1,2,…,n with class qi and si. The CCBP is to pack the items into bins, where each bin contains at most Q different classes and has total items size at most B. This CCBP is known to be NP-hard combinatorial optimization problems. In this paper, we used an ant colony optimization (ACO) approach with a simple but very effective local search algorithm to resolve this NP-hard problem. After the experimental design, limited computational results show the efficiency of this scheme. It is also shown that the ACO approach can outperform some existing methods, whereas the hybrid approach can compete with the known solution methods.

Authors: Wang Rong Jyue , Xu Jia Ming
Published: March 2013

This paper studies and implements “high efficiency power management system and intelligent battery-set charger system” for “the Intelligent Servant Robot”. This power management system provides high quality and efficiency electric power supply for all subsystems of the servant robot and accurately estimates the residual capacity of battery set system of the servant robot. This servant robot will be charged by the intelligent battery-set charger when the residual capacity of battery sets is insufficient. This servant robot can take the elevator, follow the user, carry articles, and provide the service of campus security patrolling and monitoring. LiFePO4 batteries are chosen as main power supply of the servant robot. The LiFePO4 battery-set system is divided to two subsystems which are the power battery-set (36V/20AH) for motors and the system battery-set (48V/10AH) for PC and MCUs, respectively. High efficiency power management system can measure the basic information (voltage, temperature, and current), provide protection, and give alarm for battery-set system. For the power converter module design of the intelligent battery-set charger, the main structure will use the boost power factor corrector to cascade the full-bridge power converter. The former mainly offers the power input of the high power factor, and the latter adopts the soft-switching and synchronous rectification technology in order to improve its electric conversion efficiency. For the construction of two-stage controllers, the single digital microchip controller is adopted to avoid the interference of high frequency switching of traditional power structure which uses two microchips. The experiment results have demonstrated: 1. the battery-set system can provide over two hour operation of the servant robot continuously. 2. the power management system can accurately estimates the residual capacity of battery set system. 3. the lithium-ion battery protection circuits can cut off the power apply and give the warnings when the battery set is operating under abnormal status. The battery charger allows 110V or 220V input voltage and provides the biggest 20A current to charge battery set. The power battery set can charge up to 90% capacity within one hour.
Analytical Research on Sign and Symbol of Two Avant-Garde Women Designers’ Works
Authors: Peng Li Hsun , Hsueh Chia Hsin , Lou Jeng Jia
Published: March 2013

We live in a visually intensive society. Visual symbols are one of the most important keys to communication in the design field. Usually, the symbolic meaning of artwork is closely related to its historical background, culture, socio-political environment and economic constructions. This study aimed to investigate two women designers in the Avant-Garde era, which applied cultural hybridity to their art works and managed to stand out in their field, which was dominated by male designers. We will take Clarice Cliff and Sonia Delaunay as the core cases to analyze and collaborate. As we know, these two women designers are two important fashion designers that represent different styles in design history. Their works glorify symbol in the rhythmic relations of its simultaneous contrasts. In addition, both of their styles were influenced by the merge of divergent cultures. Thus, the primary design of this study focuses on hybridity in symbol and sign. We tend to understand how cultural elements have inspired these two designers’ fashion works in visual communication. The reason why we take these two women designers as the main analytic subjects is because of their uniqueness, which represents one interpretation of the awareness of Avant-Garde production. By using Bricolage and Phenomenography as the main methodologies, and the use of Third Space Identity and Hybridity as our research theories, through an analysis of papers and cases, we hope to explore the symbolism and meaning represented by these two designers from design and culture perspectives.

The users expect to modify or successively design the products after purchase according to their own creative needs. “User creativity orientation” becomes a focus in new product development. Products which facilitate user’s creativity can be viewed as a creativity platform. The development of software in this aspect has been going on for years, while the research and relevant discourses on physical products are still lacking. This study proposes a development model of User Creativity Platform (UCP) for physical products, which includes eight steps: (1) User creativity needs exploration, (2) Functionality classification, (3) Primary and secondary components development, (4) Creativity-friendly interface design, (5) Design prototyping, (6) Creativity potential confirmation, (7) Intellectual property protection, and (8) Implementation. According to the proposed model, a set of the storage furniture has been developed and successfully granted invention patent. The model opens up a new dimension for designers to develop a user-friendly interface for user creation, rather than merely for user assembly. The feasibility of the model was also validated on the flexible furniture and toy design for pre-school kids.

Using User Scenarios to Exemplify Human-Centred Design Approach for Taiwanese Housing Developments
Authors: Li Zuo Long , Wen Kuo Hsun , Lam Artde D. Kin Tak
Published: March 2013

The user-centred design approach to housing development requires definitive processes to predict homebuyers’ existing and future needs. The scenarios of use offered here establish parameters for design when the actual situation of future occupants is not known, thereby modelling the attitudes and responses of potential homebuyers throughout design and construction. To develop the highest level of customisation to meet homebuyers’ specific requirements and changing needs over time, the vertical and horizontal relationships between the different stages of housing development is especially considered. This paper advances scenarios for the ‘use’ and according reconfiguration of the base building for Taiwanese housing development to accommodate homebuyer’s individual and changing circumstances, needs and preferences over times. Following the concepts of ‘support’ and ‘in-fill’, each interior configuration is presented at two stages — service stage and interior fit-out stage — during which detachable interior modules are organized to create rooms, storage, partitions, cabinets, and water supply and drainage facilities, electrical wiring, communication lines and gas piping is distributed from the service docks to the structural envelope of the building shell. The representation of the dwelling at the interior fit-out stage indicates the lifestyle and life stage of residents and the flexibility of interior design that can be achieved through the base building system. The transition from one scenario of use to another demonstrate that all interior walls are reconfigurable, highlighting the ability of the home to be altered over time.

Published: March 2013

In Taiwan, breast cancer has become the second leading type of cancerous diseases among women. The incidence and mortality rates keep rising, and mammography remains to be the only effective screening technique which is capable of detecting breast cancer at an early stage. High mammographic density is a strong risk factor for breast cancer. Based on BI-RADS categories, mammograms are classified into four categories (D1-D4) based on the percentage of dense area (PDA). However, reporting of breast density suffers from high inter and intra observer variability. Because the risk of breast cancer is at least three times greater in women with density (D3&D4) than in women with density D1, this paper proposes a local entropy method to identify the higher density (D3&D4) from (D1&D2) by two features. There are 406 mammograms with four categories collected for the test. The higher density (D3&D4) can be identified from lower density (D1&D2) in the correction of 100%. The Az of receiver operating characteristic curve of 0.9996 can be achieved.

By June 2008, Technorati, an internet search engine, was indexing 112.8 million blogs and over 250 million pieces of tagged social media. Blogs allow millions of people to easily publish their ideas and millions more to read and evaluate and comment on them. When bloggers write things on their blog they became public. Although bloggers use blogs for many different functions and would likely provide many different definitions of blog (Stutzman, 2004), as we have seen, many bloggers perform journalistic functions. Therefore most moral code for bloggers is credibility in a journalistic sense (Blood, 2002; Dube, 2003), but they are nonprofessional without such code. Generally, blog audiences are built on trust, so bloggers should be honest and fair in gathering, reporting and interpreting information. For example, bloggers should disclose every benefit to any monetary (or other potentially conflicting) interests when appropriate. However, there has been almost no talk about this kind of ethics in the blog world. This study designed three ethical scenarios of blogger behavior against ethics code. Scenarios include blogger promoted her favorable food without disclosure conflict of interests, post other people’s entries without referencing material, and decoding other bloggers’ picture. The purpose of current research was to examine the perception of moral intensity and how the perception directly affected the specific processes of moral decision making of bloggers related to three scenarios.

Libraries have always played important roles in information provision services. In particular, university libraries have become a major source for teachers and students to acquire important information. University libraries use websites as the media for information dissemination and the tools for extended services, thereby ensuring more extensive and comprehensive circulation of information that transcends time and space. Library websites provide community services that users can make the most direct and active contacts with libraries through the community platforms. Library information, on the other hand, can enhance user interactions with librarians through the website community services. Targeting the 148 university library websites, a survey was conducted in this paper to understand how the libraries cope with the Internet era, and give a focus to and enhance the library website services and readers’ effectiveness of use. The survey also allows one to gain an insight into the current social network services; SNS provided by the university libraries. In addition to the weblog (blog), micro-blogging community services, such as Facebook, Twitter, and Plurk have also been added in recent years. Regardless of which community platform the library uses, it hopes to strengthen the exchanges of messages between readers, thus achieving more interactive library services and enabling the user and librarian to establish close community relationships.

The purpose of this study is to use the software of MATLAB for processing the direct and reflected signals of GPS to monitor altitude of water surface in the water flume, as well as to establish a practicable technique of measuring sea water level. It is because before determining water wave pattern, the feasibility and accuracy of reflected GPS method must be proved. Therefore, there was a field test in the Mid-size wave flume of the Tainan Hydraulics Laboratory, National Cheng Kung University. After improving RGPS positioning procedure, the tranquil water level and the steadily descending of water level observation for one hour were performed. In this research, an integrated GPS receiver that employed direct and reflected GPS signals for the measurement was introduced. Both RHCP and LHCP antennas were employed to simultaneously receive the L1 and L2 carrier phase of direct and reflected signals. After the data analysis of the GPS observation, the position of signal reflection and the water level of the wave were solved. The results of the RGPS, wave gauge, and staff meter were coincided within 0.5cm ~ 1.0 cm. The differences between the reflection heights of this GPS system and the record of wave gauge were almost identical within 90%. It is proved the reflected GPS technique is possible to monitor water surface altitude and determine water wave patterns.

Energy-efficient routing is a very important issue in wireless sensor networks. An efficient routing method can avoid unnecessary data transmission and thus saves more power to extend the life of a network. The Connected Dominating Set (CDS) is a commonly used routing method which serves as a virtual backbone for a sensor network to achieve better transmission performance. The primary advantage of a CDS is its ability to adapt to the rapidly changed network topology. The construction of the CDS is a well-studied problem in an undirected unit disk graph, in which sensors are assumed to have the same transmission range. However, in practice, the sensors could have different transmission ranges due to their residual power or energy-saving mechanisms. The difference of transmission radius may form a one-way link between two nodes. Therefore, in this paper, we model the network as a directed graph and consider the CDS construction problem in such environment. We propose algorithms to construct a Strongly Connected Dominating Set (SCDS) which is a routing backbone that provides the service of efficient bidirectional data transmission between any two sensor nodes in the network.

In this paper, an improved polytomous item relational structure theory based on Q-matrix theory is proposed, using Tatsuoka’s Q-matrix theory, we can construct the test with all efficient items which are fitting in with the given relational structure of cognitive attributes, and then, before the test, using Liu’s before-test item ordering theory, an ideal relational structural graph of itemscan be constructed, and the real efficient items can be obtained accordingly. After testing the students, an after-test structure of items can be estimated by using the Liu’s polytomous item relational structure theory. Furthermore, using Liu’s criterion related validity index, we can evaluate the estimated item relational structure of the test, and the results could be useful for cognitive diagnosis and remedial instruction.

The windage yaw of suspension string under dynamic wind was analyzed with the method of finite element (FEM). By using finite element software ABAQUS, the windage yaw angle of suspension string under gust and pulsating wind for 500kV high voltage transmission line was also computed and compared with the result calculated by traditional statics method, it clearly shows that the windage yaw angles of suspended under those two kinds of dynamic winds are larger than those determined by existing design discipline of high voltage transmission line, which may be one of the reasons for flashover caused by windage yaw happening frequently.
