Many knowledge-sharing activities take place in educational institutions, both formally and informally. If this activity is organized with good knowledge management, then this will support a faster knowledge sharing process to get quality and innovative ideas. This paper aims to obtain a summary of existing research, issues, and opportunities for further analysis on knowledge-sharing (KS) practices in academic institutions. The phases of the systematic literature review (SLR) method are described based on Kitchenham (2009) guideline. We found 21 articles, seven articles from IEEE, nine articles from Science Direct, and five articles from Springer. The collection of research data on knowledge sharing has been carried out in the United States, Australia, China, Cyprus, United Kingdom, Ghana, Hungary, Indonesia, Iran, Israel, Italy, Jordanian, Malaysia, and Saudi Arabia, with the most research locations being Malaysia (14%) and Saudi Arabia (19%). We also attempted to identify the research topic trend of knowledge sharing research in academic institutions. We found two types of research trends of knowledge sharing research in university, including factor analysis and architecture development. Of the two categories of research trends, 76% discussed factor analysis, and 24% discussed architectural development. We also identified six methods in KS research including Partial Least Square Structure Equation Modeling (PLS-SEM), questionnaire, data triangulation, focus groups discussion, observation and interview. Moreover, the most used method in related research is questionnaire, because it is a relatively inexpensive, fast and efficient way of collecting large amounts of information. © 2021 IEEE.

In a core disruptive accident (CDA) of a Fast Breeder Reactor, the post accident heat removal (PAHR) is crucial for the accident mitigation. The molten core material should be solidified in the sodium coolant in the reactor vessel. In the present experiment, molten material is injected into water to experimentally obtain fragments and the visualized information of the fragmentation. The distributed particle behaviour of the molten material jet is observed with high-speed video camera. The distributions of the fragmented droplet diameter from the molten material jet are evaluated by correcting the solidified particles. The experimental results of the mean fragmented droplet diameter are compared with the existing theories. Consequently, the fragmented droplet diameter is close to the value estimated based on the Kelvin-Helmholtz instability. Once the particle diameter of the fragmented molten,material could be known from a hydrodynamic model, it becomes possible to estimate the mass ratio of the molten particle to the total injected mass by combining an appropriate heat transfer model The mass ratio of the molten fragment to total mass of the melted mixed oxide fuel in sodium coolant estimated in the present study is very small. The result means that most of the molten mixed oxide fuel material injected into the sodium coolant can be cooled down under the solidified temperature, if the amount of the coolant is sufficient.

Sokoban-type puzzles and their variants involve complex planning and decision-making challenges in wide and deep search spaces. Such scenarios are interesting for testing path-planning algorithms. This document uses A * and IDA * (Iterative Deepening A *) algorithms to solve Zen Puzzle Garden game boards; a Sokoban-type puzzle where you need rake the sandy area completely. The algorithms are evaluated in terms of speed and node expansion in moderately complex boards. Additionally, we implement three improvements: transposition tables, move ordering, and deadlock tables. The results show that IDA * with the three proposed improvements is on average faster than A *. Although its strength is its low memory usage, it can be seen that it is very competitive versus A * in terms of time usage. Transposition tables and deadlocks tables reduce by 500 times the number of nodes expanded by the IDA * without improvements. On the other hand, the ordering of nodes is not very effective for some boards, which causes a worse performance of the IDA * algorithm, giving rise to greater exploration in boards that do not lead to the solution. Studying these algorithms can be beneficial in the field of path-finding for Sokoban-type game domains or solver-based procedural content generators.

When laboratory testing is inconvenient, numerical modelling of infilled frames is required in order to represent the elastic and inelastic behaviour of these structures. However, the choice of model is very complex, as an infilled frame is made up of various materials such as bricks, mortar, concrete and reinforcements. The most accurate approach to modelling is a technique that is capable of representing the actual behaviour of the structure. In this study, we carry out numerical analysis and compare two modelling techniques, meso and macro modelling, in terms of the structural response produced. A meso model of an infilled frame has the advantage of capturing the detailed local behaviour of the panels, but has disadvantages such as complexity and high computational load. The accuracy of the structural response modelled with a meso approach is shown to have a similarity of 98% with the test results. In contrast, macro modelling using diagonal struts can significantly reduce the analysis time without compromising the accuracy of the results. This method can also accurately reproduce the nonlinear global structural behaviour. The disadvantage of this type of model is that the resulting structural response cannot represent the local damage to the masonry panel in detail. The similarity between the behaviour of the macro model and the experimental results is shown to be 104%. We find that a meso model of the infilled frame is more responsive to the initial variables derived from test results for the materials used in the structure. This is obvious in the initial stages of creating a meso model based on test data on masonry panels, as the structural response is much closer to the test results than that of the macro model. This may be because the geometric and mechanical behaviour of the meso model is closer to the actual conditions. The damaged states of the infilled frame based on the local behaviour in the meso model are related to the structural-nonstructural elemen

This paper describes a method of power assist control for lower body based on neuromuscular signal, s-EMG (surface ElectroMyogram/Myoelectricity), and impedance adjustment around knee joint with the assist system, HAL (Hybrid Assistive Leg) -3 we have developed. Virtual Torque calculated by s-EMG enabled the HAL-3 to be operated as to intention of the experimental subject put on HAL, and assist the motion of lower body by predicting the moment around joints. Besides, the operator was able to swing the leg lighter by reducing the inertia and viscous friction around joint of the subject and HAL-3. In order to verify the proposed method, experiments for simple motion was performed with impedance values found by parameter identification with RLS (Recursive Least Square) method. The evaluation of assisted motion was done by Assist Efficiency (AE) calculated from s-EMG in nearly proportion to the operator's muscle force. The results showed the response of operational signal into actuator with impedance adjustment was improved dramatically, and the amplitudes of s-EMG were reduced significantly, then we could confirm the availability of impedance adjustment.

In this paper, we present a novel self-generating algorithm for behavioral evaluation, which is used to evaluate self-selected behaviour in a reinforcement learning system. This behavioral evaluation is composed of rewards and self-evaluated standards. Rewards are given by the operator as one of the methods for understanding the purpose of tasks; and self-evaluated standards are obtained as the result of executions. Each robot can generate the evaluation depending on its situations by using the proposed method, and therefore the robots can create cooperative behaviours even if the number of robots or tasks is changed dynamically. We performed simulation experiments to study the effectiveness of the proposed method. The experimental results confirm that each robot can generate evaluations for creating cooperative behaviours without changing the algorithm during the simulation experiments.

Activated carbon is a versatile porous material that widely applied to purify, deodorize, decolorize, remove or reduce some gases harmful constituents and storage of gas. For different application different characteristics of activated carbon is required. This paper concerns to find out the characteristics of activated carbons derived from tabah bamboo (Gigantochloc nigrociliata) that physically activated with different activation holding time. Prepared tabah bamboo was carbonized by heating up to the temperature of 800 °C for two hours. The char produced was powdered and then activated physically by heating up to 800 °C, soaked at that temperature during each 1, 1.5 and 2 hours under 100 mL/min N2 flow. Activated carbons manufactured were characterized by proximate and ultimate analyses and SEM observation. The results show that the highest fix carbon (82.52%) and lowest ash (5.91 %) was obtained at 1 hour soaking time with moisture and volatile contents were 3.56% and 8.00 % respectively;the highest carbon (C) content of 84.16 % was yielded at soaked time of 1.5 hours;SEM observation shows that there were significant differences of morphology structure between raw material and activated carbons for all of the soaking time variations. The pores structures have been formed in the activated carbons produced. © Published under licence by IOP Publishing Ltd.

Knowing if a Sokoban level has a solution requires a high investment of computational resources. This also happens when estimating difficulty; heuristics may not be precise, only work for simplified cases, be discontinuous and take much computing time. The calculation of high-fidelity heuristics is expensive and the performance of optimization systems is reduced by the time they take to deliver the result. In this article, two Convolutional Neural Networks (CNN) are implemented, a classifier of resolvable Sokoban boards and a regressor that predicts the number of pushes necessary to solve them. These obtained an accuracy of 79 % and MAE of 28, respectively. Trained models are useful in systems that do not require optimality, but rather guidance within the search space that balances time and quality. These networks can be used as surrogate methods, replacing high-fidelity heuristics that take too long.

Timing verification df asynchronous sequential circuits with specifications - A method of reducing state transitions to be verified in detail

引用

SYSTEMS AND COMPUTERS IN JAPAN 1996年第11期27卷 53-63页

作者： Ohnishi, A Sugiyama, Y Okamoto, T Faculty of Engineering Okayama University Okayama Japan 700 Atsushi Ohnishi:graduated in 1991 from the Dept. Inf. Okayama Univ. where he received his M.S. degree in 1993 and admitted to the doctoral program Grad. Sch. Nat. Sci. He is engaged in research on design verification for asynchronous sequential circuit. Members

One of the important issues in the asynchronous sequential circuit is to verify that the state transitions as stated in the specification occur even if there is a delay variation in the element. When the exiting timing verification method is applied to this problem, however, the transient and other states must be examined, which requires an exponentially long time in the verification. This paper presents a formal procedure based on the circuit structure and the relation between the specification and the circuit, where the state transition to induce the transition in the specification is determined and the state transition to be verified in detail is restricted without generating the transient and other states. First, the time-invariant input values and state variable values are considered, and a sufficient condition is given for the above restriction. The sufficient condition ensures that the state transition occurs as is stated in the specification, independently of the element delay. A decision procedure for the sufficient condition is presented, and the time complexity is examined. It is shown that the proposed method is useful in reducing the verification time compared to the existing verification method. The sufficient condition is applied to sample circuits, and it is shown that the detailed verification can be omitted by the factor of 16/17 for the ring arbiter, and 20/24 for the D flip-flop. Thus, it is expected that the time for the verification can be reduced greatly by the proposed method.
