Effective training is essential for human teleoperators to deliver satisfactory performance in actual tasks. Teleoperation is naturally a very difficult task due to the absence of naked-eye vision that cripples the cognitive behavior of the remote operator. Camera vision somehow is not a satisfactory substitution. However, training with naked-eye vision feedback may help human teleoperators to learn how to deliver satisfactory performance when they actually interact with camera vision. This study was carried out to further investigate this hypothesis, and to quantitatively supplement it with experimental proofs. For this cause, the recently built telerobotic test-bed between KAIST (Korea) and Saga University(Japan) was reshaped to a telerobotic mini-golf system, which is the trial experiment in this study. The performance of the players with and without naked-eye training was compared and quantitatively evaluated. The effectiveness of training with naked-eye vision was verified as an essential part in training human teleoperators.

In [1] it was proved that 20 out of 64 PGV-hash functions [2] based on block cipher are collision resistant and one-way-secure in black-box model of the underlying block cipher. Here, we generalize the definition of PGV-hash function into a hash family and prove that besides the previous 20 hash functions we have 22 more collision resistant and one-way secure hash families. As all these 42 families are keyed hash families, these become target collision resistant also. All these 42 hash families have tight upper and lower bounds on (target) collision resistant and one-way-ness. © Springer-Verlag Berlin Heidelberg 2004.

KL-Miner [9] is a datamining procedure that, given input data matrix M and a set of parameters, generates patterns of the form R ∼ C/7- Here R and C/γ are categorial attributes corresponding to the columns of M, and 7 is a Boolean condition defined in terms of the remaining colums of M. The pattern R ∼ C/γ means that R and C are strongly correlated on the submatrix of M formed by all the rows of M that satisfy γ. What is meant by "strong correlation" and how are R, C and γ generated is determined by the input parameters of the procedure. KL-Miner conforms to the GUHA principle formulated in [1], It revives two older GUHA procedures described in [2]: it is very much related to CORREL and contains a new implementation of COLLAPS as a module. In this paper, we mention the motivation that leads to designing of KL-Miner, describing our new implementation of COLLAPS and giving application examples that illustrate the main features of KL-Miner.

RoboCup has been known for the goal of “creating robots capable of beating the world cup in 2050.” Clearly, we stated this goal back in 1996 not as an exact scientific goal, but as an audacious challenge to pursue. We aimed at creating a far away target for RoboCup researchers, as we were well aware that the development of fully autonomous soccer robots capable of competing against human world champion soccer players was a rather long term research project.

DNA electronics circuits require an efficient way to accurately position and individually manipulate DNA molecules. The recent development of atomic force microscopy (AFM) seems to be a promising solution. We have recently developed an AFM based augmented reality system. This new system can provide both real-time force feedback and real-time visual feedback during nanomanipulation. We have shown that nano-imprinting and manipulation of nano-particles and nano-rods can be easily performed under assistance of the augmented reality system. In this research, the system's ability is extended to manipulation of DNA molecules. Using a polynomial fitting method, the deformation of DNA molecules is displayed in real time in the augmented reality system during manipulation. Indeed, DNA molecules adopt many different structures including kinks, bends, bulges and distortions. These different structures and inappropriate physical contacts may result in the controversy of DNA conductivity reported over the last decade. The AFM based nanomanipulation system can be used either as a nanolithography tool to make small gap electrodes or a nanomanipulation tool to elongate, deform and cut DNA molecules. The measurement of the conductivity of DNA molecules in their different shapes and structures is a promising method to find conclusive evidences, which verify the electrical conductivity of DNA molecules.

In this paper, we present a method of recognizing inclined, rotated characters. First we construct an eigen sub-space for each category using the covariance matrix which is calculated from a sufficient number of rotated characters. Next, we can obtain a locus by projecting their rotated characters onto the eigen sub-space and interpolating between their projected points. An unknown character is also projected onto the eigen sub-space of each category. Then, the verification is carried out by calculating the distance between the projected point of the unknown character and the locus. In our experiment, we obtained quite good results for the CENTURY font of 26 capital letters of the English alphabet (A, B, ....,Z). This method has the added advantage of obtaining the recognition result (category) and angle of inclination at the same time. © 2003 IEEE.

Recent research has shown the integration of multiple classifiers to be one of the most important directions in machine learning and data mining. It was shown that, for an ensemble to be successful, it should consist of accurate and diverse base classifiers. However, it is also important that the integration procedure in the ensemble should properly utilize the ensemble diversity. In this paper, we present an algorithm for the dynamic integration of classifiers in the space of extracted features (FEDIC). It is based on the technique of dynamic integration, in which local accuracy estimates are calculated for each base classifier of an ensemble, in the neighborhood of a new instance to be processed. Generally, the whole space of original features is used to find the neighborhood of a new instance for local accuracy estimates in dynamic integration. In this paper, we propose to use feature extraction in order to cope with the curse of dimensionality in the dynamic integration of classifiers. We consider classical principal component analysis and two eigenvector-based supervised feature extraction methods that take into account class information. Experimental results show that, on some data sets, the use of FEDIC leads to significantly higher ensemble accuracies than the use of plain dynamic integration in the space of original features. As a rule, FEDIC outperforms plain dynamic integration on data sets, on which both dynamic integration works (it outperforms static integration), and considered feature extraction techniques are able to successfully extract relevant features. © Springer-Verlag Berlin Heidelberg 2003.

A two-stage face recognition algorithm is proposed. In the first stage, the mutual information match is applied to reduce the candidate pattern amount in the database. In the second stage, the principal component analysis (PCA) and linear discriminant analysis (LDA) are applied to the probe image to extract the corresponding features, which will be used in classification. The approach is tested on ORL database, Shimon database and Harvard database. The experimental results demonstrate that the performance of this system is superior to other algorithms on the same database. © 2003 IEEE.

A standard PC platform based simulator system for personnel training in anti-tank guided missile (ATGM) systems.has been designed and implemented;its operation is managed through instructor-trainee interaction. It makes use of object-oriented simulation modeling, 6 degree-offreedom (6DOF) missile model and mask modeling of terrain and weather conditions. The main topic of research are the short-range and line-of-sight (CLOS) missiles as well as their guidance and control and target selection and tracking in combat situation. The simulation model specifications are built around the set of concurrent cooperating objects, including representation model of the system's environment. The set of compatible models and software implementations for missiles and moving ground targets, involving their interrelated kinematics, has been elaborated by own research entirely. An appropriate designed user-system interface employing Visual Basic enhances the instructor-trainee co-operation. Its significance stems fiom being usable for personnel training and simulating all typical combat situations given country's landscapes, and being amenable to adjustments to serve a combat command and control instrument if endowed with some hardware-in-the-loop (HIL) elements and interface to launching platform. In addition, it is aimed for investigating new tracking algorithms in multi-target environment. © 2003 IEEE.
