The melting points of Cr3C2-C peritectic (1826degC) and Cr7C3-Cr3C2 eutectic (1742degC) alloys were investigated as high-temperature fixed point cells for thermocouple calibration. Pre-tests were performed to establish a suitable procedure for the construction of contact thermometry cells based on such chromium-carbon mixtures. Two cells were constructed following two different possible procedures. The two above melting points were successfully observed for one of these cells using tungsten-rhenium alloys thermocouples.

In this paper, we propose a robot navigation interface using a touch-pen. Generally, the global map building and position estimation are very difficult in the disaster site. In the proposed system, local sensory information is mainly used for the robot navigation. The local environment map is displayed for a robot operator, and the operator inputs the goal point on the map for the robot navigation. The desired trajectory and velocity are calculated according to the operatorpsilas command and then the robot automatically moves to the goal position.

Learning performance of natural gradient actor-critic algorithms is outstanding especially in high-dimensional spaces than conventional actor-critic algorithms. However, representation issues of stochastic policies or value functions are remaining because the actor-critic approaches need to design it carefully. The author has proposed random rectangular coarse coding, that is very simple and suited for approximating Q-values in high-dimensional state-action space. This paper shows a quantitative analysis of the random coarse coding comparing with regular-grid approaches, and presents a new approach that combines the natural gradient actor-critic with the random rectangular coarse coding.

The main purpose of this paper is to study the utilization of wide area (remote) information obtained via synchronized phasor measurement in the design of power system stabilizer. We aim to advance the performance of the conventional power system stabilizer that is designed essentially by using local measurements as input signals. Both the wide area signal from some remote area and the local signal are employed as the input signals for the power system stabilizer installed on the generating unit. The proposed multi-input power system stabilizer is investigated for enhancing the stability of the overall system. Results from applications to a multi-area power system are demonstrated.

For high nonlinearly or unknown systems, the interest is toward data-driven methods for obtaining the system model. Fuzzy-rule-based modeling is a suitable tool that combines good approximation properties with a certain degree of inspects ability. The rough set theory is successes to deal with imprecise, incomplete or uncertain for information system. Fuzzy set and the rough set theories turned out to be particularly adequate for the analysis of various types of data, especially, when dealing with inexact, uncertain or vague knowledge. In this paper, we propose an novel algorithm, which termed as rough-based fuzzy C-regression model (RFCRM), that define fuzzy subspaces in a fuzzy regression manner and also include rough-set theory for TSK modeling with robust capability against outliers.

We focus on potential capability of a profit sharing method (PS) in non-Markov multi-agent environments. It is shown that PS has some rationality in non-Markov environments and is also effective in multi-agent environments. However, conventional PS uses only a reward to learn suitable rules. On the other hand. ldquopenalty avoiding rational policy making algorithm (PARP)rdquo is based on PS and uses not only a reward but also penalties. PARP is improved to save memories and to cope with uncertainties, which is known as ldquoimproved penalty avoiding rational policy making algorithm (improved PARP).rdquo There is another critical problem we must cope with when we apply PS based methods to real environments; we need a huge amount of state information and most of states take continuous values. One solution for this problem is to approximate the states with a function approximation method, e.g. tile coding. In this paper, first, we extend improved penalty avoiding rational policy making algorithm to tile coding environments. Then, we compare the extended method with conventional methods to show the effectiveness through an application to a keepaway task in a soccer game.
我们重点研究了利润分享方法在非马尔可夫多智能体环境中的潜在能力。结果表明，PS算法在非马尔可夫环境下具有一定的合理性，在多智能体环境下也是有效的。然而，传统的PS只使用奖励来学习合适的规则。另一方面。定量避免理性决策算法(PARP)是一种基于PS的既有奖励又有惩罚的算法。为了节省内存和应对不确定性，对PARP进行了改进，称为ldquoimproved penalty avoidance rational policy making algorithm (improved PARP)。当我们将基于PS的方法应用于实际环境时，我们必须处理另一个关键问题;我们需要大量的状态信息，而大多数状态都是连续的。这个问题的一个解决方案是用函数近似方法来近似状态，例如tile编码。本文首先将改进的避免惩罚的理性策略制定算法推广到tile编码环境中。然后，我们将扩展方法与传统方法进行比较，通过应用于足球比赛中的控球任务来证明该方法的有效性。

We present a promising system to simultaneously detect and track multiple humans in the outside scene using laser and vision. The useful information of laser and vision is automatically extracted and combined in a Bayesian formulation. In order to compute MAP estimation, an effective probabilistic detection-based particle filter (PD-PF) has been proposed. Experiments and evaluations demonstrate that not only can our system perform robustly in real environments, but also obtain better approximation of MAP than previous methods in most complex situations.

An alpha sensor implies an angle of attack sensor to measure the angle between the aircraftpsilas reference line and the relative wind vector to the aircraft. Accurate measurements of AOA (angle-of-attack) are important to identify the aerodynamic coefficients and to evaluate the flight performance of an UAS. For a small scale UAS, AOA is usually estimated by AHRS (attitude heading reference system) combined with an GPS receiver, but this method provides poor information in general. In this paper, a null type alpha sensor developed by aerospace control and system Lab. in Inha University is introduced. The null type alpha sensor has many advantages compared with other kinds of alpha sensors. Most of all it has uniform error characteristics against AOA. And, as the speed increases, the sensor provides more accurate measurements.

One advantage of pedal robot is its availability in uneven terrain such as steps, messy room, disaster area, mountain or outer planet. On the other hand, pedal robot tends to be less stable and more complex in its mechanism or algorithm than wheel robot does. In this paper, the authors propose a novel pedal robot system that overcomes both stability and complexity. The system is named as ldquoUniversal Unipods,rdquo which consists of a lot of unipod robots to be attached on a single load as a body. A unipod robot has very simple underactuated mechanism and it doesnpsilat communicate each another unlike many other multi-agent robot systems. Then, basic validity and potential availability are verified by computer simulations.
