Perspectives on the new National Ecological Institute in South Korea
Crane, Peter R.,Choe, Jae-C. The Ecological Society of Korea 2010 Journal of Ecology and Environment Vol.33 No.4
The Ministry of Environment of South Korea has launched its plan to establish the National Ecological Institute. An International Symposium and Workshop was held at Ewha Womans University in Seoul on Thursday, 30 September 2010, to strengthen international cooperation, networking and partnerships for the conservation of biodiversity. This symposium was attended by experts of many major institutions for biodiversity conservation from South Korea and overseas. At the symposium and workshop preceded by a keynote speech by the renowned primatologist and conservation biologist Jane Goodall the participants discussed a wide range of topics including "biodiversity conservation: in situ and ex situ approaches", "conservation of species diversity and ecosystem management", and "international cooperation for biodiversity conservation and research". As a basis for future discussions, this article summarizes how the National Ecological Institute might contribute most effectively to public life and environmental management in South Korea and worldwide. It addresses the following issues: governance and funding, synergies within Korea, participation in international networks, external advice, a broad view of ecological issues, research agenda, building on identity, public outreach, and training the next generation of scientists.
The Iconography of Gender: The Indian Uprising of 1857
( Ralph Crane ),( Radhika Mohanram ) 한국영미문학페미니즘학회 2008 영미문학페미니즘 Vol.16 No.2
In this paper we consider the influences of the Indian Mutiny or Uprising of 1857 on gender formations in Anglo-India. The first part of our paper provides a concise background to the 1857 Uprising, while the second part explores the reconstructions of Anglo-Indian masculinity and femininity in response to the events of 1857 which shook Britain`s confidence in its ability to control India. In particular we look at three examples of Mutiny iconography which open up a discourse on the status of whiteness in both Anglo-India and Britain with their implications for the relationship between race and gender in India.

Detection of Wheel Faults in Electric Vehicles via Localization Data
Robert Kidd,Dr. Carl Crane 제어로봇시스템학회 2014 제어로봇시스템학회 국제학술대회 논문집 Vol.2014 No.10
This paper addresses the detection of wheel faults in autonomous vehicles. Instead of the typically broad range of sensors involved, localization data is used to detect and classify three major faults in torque-controlled DC motors. A four wheeled vehicle is implemented in simulation with independent steering and in-hub motors to generate localization data. The vehicle model is based on extensive vehicle dynamics modeling to accurately predict a small passenger vehicle. These three faults are induced on the vehicle to determine the effectiveness of the localization method and test its ability to detect the faults and delineate between the different fault types. Lastly, an extension is outlined for detection and classification for broader error types beyond those represented by the three errors examined.

This article aims to propose the navigation algorithm for autonomous driving of the skid steering vehicles based on the geometric method. The navigation system consists of two main concepts: the Skid Steering and Pure Pursuit methods. This study combines two concepts into one formula. And adds the two-compensation coefficient at the combined formula and organizes the concepts through mathematical proofs. The proposed formula has the advantage of being similar to the control of the ordinary vehicle with an Ackerman steering hardware system in a simple way and it doesn’t necessary the modeling process of the vehicle and various road environments. In the experiments section of this article, Simulations were conducted several times by varying the compensation coefficients to examine how to change the steering characteristics of the vehicle.
Development of a Multi-resolution Parallel Genetic Algorithm for Autonomous Robotic Path Planning
Drew Lucas,Carl Crane III 제어로봇시스템학회 2012 제어로봇시스템학회 국제학술대회 논문집 Vol.2012 No.10
Deterministic algorithms such as A<SUP>*</SUP> and D<SUP>*</SUP> have been applied with great success to autonomous robotic path planning. However, as search space size increases numerous problem domains will likely become intractable when reactive behavior is desired. This is extremely relevant when considering the exponential increase in search space sizes due to any linear addition of degrees of freedom. Over the last few decades, Evolutionary Algorithms (EA) have been shown to be particularly applicable to extremely large search spaces. However, it is often assumed that generational convergence is the only measure of quality for an EA. A novel combination of the Anytime Planning (AP) criteria with multi-resolution search spaces is explored for application to high-level semi-reactive path planning. Separate populations are evolved in parallel within different abstractions of the search space while low cost solutions from each population are exchanged among the populations. Generational evaluations in low-resolution search spaces can be evaluated quickly generating seed candidate solutions that are likely to speed convergence in the high-resolution search spaces. Convergence rates up to 4× were achieved along with modest decreases in path cost. Parallel GPU computation was then applied to allow reactive searching up to 40Hz in search grids up to 8192×8192 cells.
