Safety Intelligence And Legal Machine Language: Do We Need Three Laws Of Robotics?, Chien Hsun Chen, Y. H. Weng, C. T. Sun Aug 2009

Safety Intelligence And Legal Machine Language: Do We Need Three Laws Of Robotics?, Chien Hsun Chen, Y. H. Weng, C. T. Sun

Chien Hsun Chen

In this chapter we will describe a legal framework for Next Generation Robots (NGRs) that has safety as its central focus. The framework is offered in response to the current lack of clarity regarding robot safety guidelines, despite the development and impending release of tens of thousands of robots into workplaces and homes around the world. We also describe our proposal for a safety intelligence (SI) concept that addresses issues associated with open texture risk for robots that will have a relatively high level of autonomy in their interactions with humans. Whereas Isaac Asimov’s Three Laws of Robotics are frequently …


A Neural Network: Family Competition Genetic Algorithm And Its Application In Electromagnetic Optimization, Chien Hsun Chen, P. Y. Chen, H. Weng Jan 2009

A Neural Network: Family Competition Genetic Algorithm And Its Application In Electromagnetic Optimization, Chien Hsun Chen, P. Y. Chen, H. Weng

Chien Hsun Chen

This study proposes a neural network-family competition genetic algorithm (NN-FCGA) for solving the electromagnetic (EM) optimization and other general-purpose optimization problems. The NN-FCGA is a hybrid evolutionary-based algorithm, combining the good approximation performance of neural network (NN) and the robust and effective optimum search ability of the family competition genetic algorithms (FCGA) to accelerate the optimization process. In this study, the NN-FCGA is used to extract a set of optimal design parameters for two representative design examples: the multiple section low-pass filter and the polygonal electromagnetic absorber. Our results demonstrate that the optimal electromagnetic properties given by the NN-FCGA are …


Toward The Human-Robot Co-Existence Society: On Safety Intelligence For Next Generation Robots, Chien Hsun Chen, Y. H. Weng, C. T. Sun Jan 2009

Toward The Human-Robot Co-Existence Society: On Safety Intelligence For Next Generation Robots, Chien Hsun Chen, Y. H. Weng, C. T. Sun

Chien Hsun Chen

Technocrats from many developed countries, especially Japan and South Korea, are preparing for the human-robot co-existence society that they believe will emerge by 2030. Regulators are assuming that within the next two decades, robots will be capable of adapting to complex, unstructured environments and interacting with humans to assist with the performance of daily life tasks. Unlike heavily regulated industrial robots that toil in isolated settings, Next Generation Robots will have relative autonomy, which raises a number of safety issues that are the focus of this article. Our purpose is to describe a framework for a legal system focused on …


Player Guild Dynamics And Evolution In Massively Multiplayer Online Games, Chien Hsun Chen, J. L. Hsieh, C. T. Sun Nov 2008

Player Guild Dynamics And Evolution In Massively Multiplayer Online Games, Chien Hsun Chen, J. L. Hsieh, C. T. Sun

Chien Hsun Chen

In the latest versions of massively multiplayer online games (MMOGs), developers have purposefully made guilds part of game environments. Guilds represent a powerful method for giving players a sense of online community, but there is little quantitative data on guild dynamics. To address this topic, we took advantage of a feature found in one of today’s most popular MMOGs (World of Warcraft) to collect in-game data: user interfaces that players can modify and refine. In addition to collecting data on in-game player activities, we used this feature to observe and investigate how players join and leave guilds. Data were analyzed …

Synthesis Design Of Artificial Magnetic Metamaterials Using A Genetic Algorithm, Chien Hsun Chen, P. Y. Chen, H. Wang, J. H. Tsai, W. X. Ni Jan 2008

Synthesis Design Of Artificial Magnetic Metamaterials Using A Genetic Algorithm, Chien Hsun Chen, P. Y. Chen, H. Wang, J. H. Tsai, W. X. Ni

Chien Hsun Chen

In this article, we present a genetic algorithm (GA) as one branch of artificial intelligence (AI) for the optimization-design of the artificial magnetic metamaterial whose structure is automatically generated by computer through the filling element methodology. A representative design example, metamaterials with permeability of negative unity, is investigated and the optimized structures found by the GA are presented. It is also demonstrated that our approach is effective for the synthesis of functional magnetic and electric metamaterials with optimal structures. This GA-based optimization-design technique shows great versatility and applicability in the design of functional metamaterials.


A Web-Based Tagging Tool For Organizing Personal Documents On Pcs, Chien Hsun Chen, I. W. Lin, J. L. Hsieh, C. T. Sun Jan 2008

A Web-Based Tagging Tool For Organizing Personal Documents On Pcs, Chien Hsun Chen, I. W. Lin, J. L. Hsieh, C. T. Sun

Chien Hsun Chen

Most desktop computer operating systems provide hierarchical folder mechanisms for managing electronic content, therefore hierarchies still dominate digital information management on PCs. Under certain circumstances, the properties of a folder system make it hard to locate and find specific files stored deep within a hierarchy, therefore researchers are currently studying new mechanisms for file storage, organization, and retrieval. Recently, non-exclusive and flat-network tagging mechanisms have gained popularity for managing online information and files. In this paper we discuss memory theories from cognitive psychology and their potential use in the form of tagging mechanisms for storing and retrieving personal information. Next, …


Comparing Taiwanese And American Wow Player Cultures In Terms Of Achievement, C. T. Sun, Chien Hsun Chen, J. L. Hsieh, H. Lin Sep 2007

Comparing Taiwanese And American Wow Player Cultures In Terms Of Achievement, C. T. Sun, Chien Hsun Chen, J. L. Hsieh, H. Lin

Chien Hsun Chen

When analyzing Taiwanese and American market separation and online gaming cultures, sooner or later researchers hear the assertion that players in Taiwan emphasize achievement and players in the US emphasize recreation. This belief may explain why a significant number of Taiwanese World of Warcraft (WoW) players claim that they would rather connect to North American game servers to play. To determine the truth (if any) of this belief, we investigated behaviors, tendencies, and motivations between Taiwanese and American WoW players using data collected via WoW’s unique clientdesigned user interface feature. Data on level upgrade efficiency and participation in guild-organized raids …
