  • Since container throughput is continually increasing, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations that support user needs require modeling tools that are both easy to use and sufficiently to reflect real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. This paper present the design procedure a simulator for port container terminal that was based on the object-oriented approach. The simulator in order to model and simulate the TC-based container terminals is developed.

  • Postcolonial critics have criticized Comparative Literature for exclusively studying literatures from the non-Western world through Western lenses. In other words, postcolonial criticism asserts that theorists and practitioners of comparative literature have traced the "assistance" of the classic "comparison and contrast" approach to an imperialist discourse, which sustains the superiority of Western cultures and economies. As a countermeasure to reading through the comparative lens, literary theories have offered a "juxtapositional model of comparison" that connects texts across cultures, places, and times. This paper examines practices of Comparative Literature in Vietnam, revealing how the engagement with decolonizing processes leads to a knowledge production that is paradoxically colonial. The paper also analyses implementations of this model in reading select Vietnamese works and highlights how conventional comparisons, largely based on historical influences and reception, maintain the colonial mapping of World Literature, centralizing Western, and more particularly, English Literature and in the process marginalizing the others. Therefore, the practice of juxtaposing Vietnamese literary works with canonical works of the World Literature will provoke dialogues and raise awareness of hitherto marginalized works to an international readership. In this process, the paper considers the contemporary interest of Comparative Literature practice in trans- national, trans-regional, trans-historical, and trans-cultural perspectives.

  • Most systems in tile real world are non-linear and can be represented by the non-linear autoregressive moving average (NARMA) model. The extension of fuzzy system for modeling the system that is represented by NARMA model will be proposed in this paper. Here, fuzzy basis function (FBF) is used as fuzzy NARMA(p,q) model. Then, an approach to Identify fuzzy NARMA models based on fuzzy basis functions is proposed. The efficacy of the proposed approach is shown from experimental results.

  • Recently, the growth of e-commerce in Saudi Arabia has been exponential, bringing new remarkable challenges. A naive approach for product matching and categorization is needed to help consumers choose the right store to purchase a product. This paper presents a machine learning approach for product matching that combines deep learning techniques with standard artificial neural networks (ANNs). Existing methods focused on product matching, whereas our model compares products based on unstructured descriptions. We evaluated our electronics dataset model from three business-to-consumer (B2C) online stores by putting the match products collectively in one dataset. The performance evaluation based on k-mean classifier prediction from three real-world online stores demonstrates that the proposed algorithm outperforms the benchmarked approach by 80% on average F1-measure.

  • This study is concerned how to construct a model of life as physical/ mathematical representation. This model is called here a bionic model and vibrating potential field is introduced as fundamental world background of the model. Namely, required information creating/ processing/ controlling are done on this field. Especially this paper reports how to realize the simulation of a bionic self organization and its functional expression based on the mutual actions among a set of life units.

  • In speech recognition for real-world applications, the performance degradation due to the mismatch introduced between training and testing environments should be overcome. In this paper, to reduce this mismatch, we provide a hybrid method of spectral subtraction and residual noise masking. We also employ multiple model approach to obtain improved robustness over various noise environments. In this approach, multiple model sets are made according to several noise masking levels and then a model set appropriate for the estimated noise level is selected automatically in recognition phase. According to speaker independent isolated word recognition experiments in car noise environments, the proposed method using model sets with only two masking levels reduced average word error rate by 60% in comparison with spectral subtraction method.

  • Due to uncertain environment, various parameters such as price, queuing length, warranty, and so on influence on inventory models. In this paper, an inventory-queuing-pricing problem with continuous review inventory control policy and batch arrival queuing approach, is presented. To best of our knowledge, (I) demand function is stochastic and price dependent; (II) due to the uncertainty in real-world situations, a fuzzy programming approach is applied. Therefore, the presented model with goal of maximizing total profit of system analyzes the price and order quantity decision variables. Since the proposed model belongs to NP-hard problems, Pareto-based approaches based on non-dominated ranking and sorting genetic algorithm are proposed and justified to solve the model. Several numerical illustrations are generated to demonstrate the model validity and algorithms performance. The results showed the applicability and robustness of the proposed soft-computing-based approaches to analyze the problem.

  • Paraglider has been used for a good air sports instrument by many people in the world though its short history. And manufacturers have improved it continuously. It has the great growth from the first model like parachute to the latest model that has the extreme speed, but we can improve it in more parts. In this paper, we will show the method which can improve its performance by using Axiomatic Approach.

  • An essential prerequisite for negotiating governance of 'internet,' a world of 'end to end' nature, is to guarantee end-users' participation. Internet Governance Forum (IGF), the outcome of World Summit on the Information Society(WSIS) Tunis Agenda, has played an important role as a representative mulitistakeholder - based governance model, which puts emphasis on wide range participation of stakeholders. Notwithstanding multistakeholderism materialized in IGF has been challenged, IGF itself is a unique place for participation to broad internet governance discourse, as all voices get hearing grounded on openness, inclusion, and transparency, quite distinct from the multilateral negotiation based model such as 'Conference on Cyberspace.' Therefore civil society which represents end-users' interest, as a crucial stakeholder of internet governance, should establish more strategic and coordinated approach to IGF itself as well as reformation discourse of internet governance. In this regard, civil society groups of Korea, began with hosting workshops and Open Forum at the 2013 IGF in Bali, Indonesia. This report also describes the detailed activities of Korean civil society group in 2013 IGF.

  • The objective of this article is to create a model of integrated management from the framework modeling of a digital collaborative network supported by knowledge engineering to make heritage site in the Brazil more effective. It is an exploratory and qualitative research with thematic analysis as technique of data analysis from the collaborative network, digital platform, world heritage, and tourism themes. The snowballing approach was chosen, and the mapping and classification of relevant studies was developed with the use of the spreadsheet tool and the Mendeley® software. The results show that the collaborative network model oriented towards strategic objectives should be supported by a digital platform that provides a technological environment that adds functionalities and digital platform services with the integration of knowledge engineering techniques and tools, enabling the discovery and sharing of knowledge in the collaborative network.
