A Sustainable Tourism Policy Research Review

After nearly three decades of development, sustainable tourism has been widely recognized in tourism policy practice and tourism research. In recent years, scholars have paid more and more attention to the topic of sustainable tourism policy research. The purpose of this paper is to analyze its development process and extract its research subject framework for reference in future research. This paper uses the systematic review method and the literature co-citation network analysis to classify the theme of sustainable tourism policy research into six categories, including: Sustainable tourism policy stakeholders, sustainable tourism policy implementation, sustainable tourism and climate policy, sustainable tourism indicators and planning, sustainable concepts in tourism policy, and the role of sustainable tourism policy. The development and implementation of sustainable tourism policies are an effective response to global environmental and sustainable development challenges. However, the current sustainable tourism policy is often economic-growth oriented, which has theoretical differences with sustainable development. At the same time, the research focus of scholars is on the impact of policies on the sustainable development of tourism, while the research on the formation process of policies and governance behaviors in the sustainable development of tourism is not enough.
Source-channel optimized trellis codes for bi-tonal image transmission over AWGN channels

We consider the design of trellis codes for transmission of binary images over additive white Gaussian noise (AWGN) channels. We first model the image as a binary asymmetric Markov source (BAMS) and then design source-channel optimized (SCO) trellis codes for the BAMS and AWGN channel. The SCO codes are shown to be superior to Ungerboeck's (1982) codes by approximately 1.1 dB (64-state code, 10/sup -5/ bit error probability). Furthermore, we compare the proposed SCO system to a more traditional tandem system consisting of a Huffman code, a convolutional code, an interleaver and an Ungerboeck trellis code. Using a facsimile image, we compare the image quality of an SCO code, an Ungerboeck code, and the tandem code. The SCO code yields the best reconstructed image quality at 4-5 dB channel SNR.
K Semantics for OCL - a Proposal for a Formal Definition for OCL

Object Constraint Language (OCL) is a formal language used to describe expressions like constraints or queries over objects in a UML model. The constraints are used to give an exact description of the information contained in the models and the queries are used to analyze these models and to validate them. The evaluation of the OCL expressions does not have side effects. In spite of the fact OCL has defined more than ten years ago, it is not yet widely adopted in industry and one reason for that is the lack of proper and integrated tool support for OCL. Another reason is that although designed to be a formal language, experience has shown that the language definition is not precise enough. Even the last OMG standard includes underspecified things and some inconsistencies. In this paper we present an executable formal semantics for a representative fragment of OCL described in K, a semantic framework suitable for defining programming languages, type systems, formal analysis tools and calculi. K has been already successfully used for giving formal definitions to several programming languages and developing analysis tools for these languages. Therefore having a formal definition for OCL in this framework has several advantages including executability (the K semantics of OCL can be used to evaluate OCL expressions for different models), an easy integration with model languages and object-oriented languages defined in K.
Design of a portable electrotactile stimulator for sensory substitution applications

The design, fabrication, and testing of an electronic stimulator for use in sensory substituion applications is discussed. The device is housed in a 5-cm*10-cm*15-cm plastic housing, weighs less than 1 kg, and is battery operated. The unit functions as part of a feedback system for people with insensate feet. By adding a special cable, the device can also be used in conjunction with a portable data-acquisition system previously developed. Controls have been incorporated to allow a researcher to determine the effect of various parameters on the quality of stimulation. The device produces a biphasic pulse with a maximal current amplitude of 20 mA and can operate for approximately 3 h. Multiplexing of the input and output channels minimizes component count as well as power consumption. <<ETX>>
Contrasting cybersecurity implementation frameworks (CIF) from three countries

Purpose This paper aims to explore the evolution of a trend in which countries are developing or adopting cybersecurity implementation frameworks that are intended to be used nationally. This paper contrasts the cybersecurity frameworks that have been developed in three countries, namely, Australia, UK and USA. Design/methodology/approach The paper uses literature review and qualitative document analysis for the study. The paper developed and used an assessment matrix as its coding protocol. The contents of the three cybersecurity frameworks were then scored to capture the degree to which they covered the themes/items of the cybersecurity assessment matrix. Findings The analysis found that the three cybersecurity frameworks are oriented toward the risk management approach. However, the frameworks also had notable differences with regard to the security domains that they cover. For example, one of the frameworks did not offer guidelines with regard to what to do to respond to attacks or to plan for recovery. Originality/value The results of this study are beneficial to policymakers in the three countries targeted, as they are able to gain insights about how their cybersecurity frameworks compares to those of the other two countries. Such knowledge would be useful as decision-makers take steps to improve their existing frameworks. The results of this study are also beneficial to executives who have branches in all three countries. In such cases, security professionals could deploy the most comprehensive framework across all three countries and then extend the deployment in each location to meet country-specific requirements.

Weight optimisation of brush-type wound-field direct current motors

Weight optimised direct current motors have been used lately as actuators for micro-robotics and biomedical equipment. Many techniques have been used in developing permanent magnet and wound-field motors, such as numerical analysis, selecting adequate magnetic material, finite element analysis and optimisation models. Yet, published articles reveal problems with wound-field motors: for example nonproportional geometry, saturated magnetic core, weak output torque and high temperature rise. A mathematical model is introduced in this paper for developing a new design method to overcome these problems. A 900 W DC motor is optimised separately and concurrently with a proportional, integral and derivative (PID) controller, as an example for illustrating the proposed method.
Conference Plenary HOW CAN INTERACTIVE MULTIMEDIA ENHANCE LEARNING

This presentation will describe work carried out within the MENO (Multimedia, Education and Narrative Organisation) project, which has investigated the role that narrative plays in a non-narrative medium. Our findings show that the commercially-produced multimedia CDs which are predominant in the school curriculum, lack the kind of task structure and interface dynamic that enable pupils to retain control of their own narrative. The presentation will describe the design features that 'afford' behaviours that generate learning. Interactive multimedia materials can enhance learning, but the learning experiences they offer must be well understood by both designers and teachers if they are to succeed in doing so.
Test education for VLSI systems design engineers

The implementation of entire systems on VLSI chips provides an opportunity for a top-down test strategy. This is possible if the systems designer is familiar with the basic concepts in test, design for testability, and system diagnosis. The paper proposes a two-step education program. The first coarse, "Essentials of Electronic Testing ", teaches the basic principles of testing. It is an undergraduate-level course and should be included in the core curriculum in addition to a VLSI design course. The second course, "Advanced Concepts in VLSI Testing", is a graduate-level course. It is useful for VLSI CAD engineers and for researchers.
Designing an Interface and Path Translator for a Smart Phone- Based Indoor Navigation System for Visually Impaired Users

According to the Braille Institute of America [1], there are 15 million blind and visually impaired people in the United States. They have different important daily needs including navigation. Visually impaired people rely on different tools and skills to navigate. They usually rely on their white canes, seeing-eye-dogs and other skills acquired over time to aid their navigation. Many technologies have been developed to assist blind users with different navigation needs. These include obstacle avoidance technologies as well as routing technologies. Any routing technology for blind requires different components including localization, map representation, path planning, interface, and a component to translate the planner output into meaningful instructions. The focus of this work is on developing the interface and the translator component of a full smart phone-based navigation system, called NavPal. The application improves on previous work by giving better quality instructions, and giving more flexibility to the user in choosing the level of verbosity and using different input/output modalities. The application tries to keep a good balance between the quality of the navigation instructions and the automatic production of these instructions. The interface was tested with eight blind users who traversed three routes, each. The results indicated that 75% of the twenty four navigation tasks were accomplished successfully, while relying only on the interface instructions. The users provided feedback on all components of the interface and provided suggestions for improvement, which will be considered in future work.
Possibilities of Force based Interaction with Robot Manipulators

One way of interaction between a human and a robot manipulator is the interaction via forces and torques. We will call it also force guidance. For this purpose the human acts on the robot arm or on the robot end-effector. From the interaction forces and torques than a suitable motion of the robot is generated. This kind of human robot interaction may be useful e.g. for the comfortable teach-in process. Commonly, positions and orientations of the robot tool are taught by the operator using the manual control pendant. With the keys on this device he or she moves the robot in joint or in task space. To improve the usability of the robot, some manual control pendants are additionally equipped with a more intuitive teach in device. It is called 6D mouse or space mouse (Hirzinger & Heindl, 1986). For further optimization of the teach-in process another way to move the robot would be force guidance. It will be shown that it is possible, with some differences, both in joint or in task space. Force based human robot interaction can be seen as a special kind of active robot force control (Zeng & Hemami, 1997). To perform this, the robot has to be equipped with a force/torque sensor (Gorinevsky et al., 1997). Usually this sensor is mounted in the robot wrist and it measures forces and torques in all Cartesian directions. The cost of such a 6D F/T sensor can exceed 10% of the price of a low payload six axes articulated robot. For that reason it should be searched for an alternative possibility of force/torque measurement. One idea is to estimate the interaction forces and torques from the joint motor currents. For this purpose an algorithm is presented and verified with experiments. Besides the kinematics of the robot motion during human robot interaction also its dynamics is important. For its representation the so called target or desired impedance behaviour will be defined as the relationship between interaction forces/torques and the velocity components of the robot motion. The simplest desired impedance behaviour is the behaviour of the mass damper system. Moreover, there are some more variants and additional features, e.g. the intuitive collision avoidance which will be described in this article. Apart from the desired impedance behaviour selected and parameterized by the operator the dynamics of the robot system has been respected. It depends on the access level of motion generation. Commonly, the robot motion is controlled by the trajectory generator. However, some robot systems permit the direct access to the position or velocity control loops which is favourable in all kinds of robot force control.

MSc THESIS Implementation of a Polymorphic Floating-Point Matrix Multiplication Unit

Faculty of Electrical Engineering, Mathematics and Computer Science CE-MS-2007-13 Floating-point matrix multiplication is presumably one of the most important kernel routines in many scientific applications. Efficient implementation of this routine is therefore critical for the overall performance of this broad range of applications. In order to accelerate the matrix multiplication kernel, we have designed and implemented a 64-bit floating-point matrix multiplication unit as a reconfigurable coprocessor. Our implementation is based on a previous proposal by Yong Dou et al. The key contributions of our work are as follows. We introduced a controller which supports the MOLEN polymorphic interface and allows for efficient operation of the multiplier processing elements. We integrated our design as a custom computing unit in a MOLEN processor prototype on real hardware. Furthermore, we evaluated the performance of the design both theoretically and by experimal results on our hardware realization. We were able to fit 9 processing elements in an XC2VP30-6 device and run the design at 100 MHz (the PowerPC core runs at 300 MHz). This yields a peak performance of 1.80 GFLOPS. Through experimental results we measured a sustained performance of up to 1.79 GFLOPS, which is very close to the peak performance of the implementation. This testifies to the efficient utilization of the processing elements. Moreover, our design is very scalable and synthesis results suggest that a performance of over 10 GFLOPS could be sustained on a single XC2VP125 device. As a practical test, we performed the LINPACK benchmark on the MOLEN processor with and without hardware acceleration. Despite memory limitations of the current MOLEN prototype, we measured speedups of up to 79X compared to the software version. Without the memory limitations, we estimate that much higher speedups of up to 3000X are possible. Implementation of a Polymorphic Floating-Point Matrix Multiplication Unit
Variations in user satisfaction with MIS

The results of a field study of management information systems (MIS) in different organizations in Australia which investigates the relationship between type of user, user involvement and user information satisfaction are reported. The results show that user MIS success (UIS) varies between users of the same MIS based on their organizational function and that user involvement in the systems development life cycle has a significant positive effect on UIS. The significance of the effect of user involvement varies for users based on their organizational function. Technical users are less satisfied with MIS than administrative users. Also, the relationship between user involvement/user control of the systems development process and UIS is significantly different for administrative and technical users. <<ETX>>
Object-oriented displays: a new type of display systems-from immersive display to object-oriented displays

We propose the concept of the "object-oriented display", which should enable an operator to perceive and operate a virtual object as if it were a real one. The object-oriented display (OOD) is a type of display system in which the surfaces of the display surround the object and not the operator. The purpose of the OOD is the presentation of virtual objects, whereas the purpose of ordinary display systems is the presentation of the virtual environment. In this project, we also describe the design and implementation of three types of object-oriented displays, (i) MEDIA-A (MEDIA-Ace), (ii) MEDIA/sup 3/ (MEDIA-Cube) and (iii) MEDIA X'tal (MEDIA-Crystal). MEDIA-A is a type of object-oriented display that is compact, light, and inexpensive. It consists of a single LCD panel and a tilt sensor. MEDIA/sup 3/ consists of four LCD panels in the shape of a cubic body. A position and orientation sensor is installed in MEDIA/sup 3/. Using MEDIA/sup 3/, a virtual object is adequately displayed by controlling the image displayed on each LCD panel, corresponding to the position of the operator's head. Thus, the virtual object appears in MEDIA/sup 3/ in its entirety. Therefore, the operator can recognize easily and intuitively the three-dimensional form and structure of the virtual object. For MEDIA X'tal, on the other hand, we use optical projection. The MEDIA X'tal solves several problems which occur when using ordinary display devices for the OOD.
Putting Facts Together: A Study of Scientific Persuasion

This paper is an empirical analysis of the way in which a group of scientists sought to maximize the attractiveness of one of their papers. It records negotiations about the title, the introduction, and the second paragraph (in which a polymer was characterized). The analysis suggests that scientists array or `network' particulars in a way which they hope will allocate appropriate relative value to elements of that array. In doing so, three factors — the citation of colleagues, the display of facts, and problems of syntax — have to be simultaneously juggled.
Agent Based Modeling for Business Gam-ing Simulation and Application for Supply Chain Management Education

Yokohama Business Game (YBG) is a business game platform supporting a development, conduct and management of games. While YBG provides various types of business game and they are used in over 70 Japanese universities, there is a difficulty in keeping game balance or finding optimal strategy when developing and/or conducting a new game. For the problems, the author proposes a gamingand-agent based modeling approach. An agent-based simulator is introduced to illustrate an effectiveness of the approach, and data generated by human player is used to design a new game. An application of the approach to SCM education is shown.

The automatic reading of unconstrained cursive city names written on real mail is considered. An analytical approach is described which first achieves an explicit segmentation of cursive words. The results after crosschecking of the zip code and the city name are a 61.7% efficiency rate and a 1.3 confusion rate, which allow operational implementation. <<ETX>>
INDUCTIVE MACHINE LEARNING IN MICROSTRUCTURES Estimating a finite element optimization using support vector machines

A support vector machine is trained to produce optimal structures. The problem of structural optimization is typically solved by a search procedure that samples and repeatedly evaluates a physics-based model, but this process is computationally demanding. Instead, the use of a learning algorithm to generate new structures based on previously optimized examples is described that provides enormous computational saving. The results have shown that the predicted structures are accurate, and the process is highly efficient for cases in which similar optimizations must be performed repeatedly, especially as the number of such optimisations grows.
