A performance comparison of fullband and different subband adaptive equalisers

We present two different fractionally spaced (FS) equalisers based on subband methods, with the aim of reducing the computational complexity and increasing the convergence rate of a standard fullband FS equaliser. This is achieved by operating in decimated subbands; at a considerably lower update rate and by exploiting the prewhitening effect that a filter bank has on the considerable spectral dynamics of a signal received through a severely distorting channel. The two presented subband structures differ in their level of realising the feedforward and feedback part of the equaliser in the subband domain, with distinct impacts on the updating. Simulation results pinpoint the faster convergence at lower cost for the proposed subband equalisers

Metaheuristic Algorithms for Convolution Neural Network

A typical modern optimization technique is usually either heuristic or metaheuristic. This technique has managed to solve some optimization problems in the research area of science, engineering, and industry. However, implementation strategy of metaheuristic for accuracy improvement on convolution neural networks (CNN), a famous deep learning method, is still rarely investigated. Deep learning relates to a type of machine learning technique, where its aim is to move closer to the goal of artificial intelligence of creating a machine that could successfully perform any intellectual tasks that can be carried out by a human. In this paper, we propose the implementation strategy of three popular metaheuristic approaches, that is, simulated annealing, differential evolution, and harmony search, to optimize CNN. The performances of these metaheuristic methods in optimizing CNN on classifying MNIST and CIFAR dataset were evaluated and compared. Furthermore, the proposed methods are also compared with the original CNN. Although the proposed methods show an increase in the computation time, their accuracy has also been improved (up to 7.14 percent).Comment: Article ID 1537325, 13 pages.

Regionalization and harmonization in TVET

A transversal skill is one of the skills needed in every type of workplace setting. There is limited information about the perceptions of which transferable skills are needed in the workplace. The objective of this study is to explore the transferable skills among students and lecturers in TVET higher learning institutions in Indonesia and Malaysia. In the present study, transferable skills consist of communication skills, collaboration skills, problem-solving skills, entrepreneurship, and learning to learn skills. A qualitative research was conducted using survey. The five Likert scale questionnaire was distributed to lecturers and students from selected Malaysian and Indonesian universities who have bachelor program in engineering. Based on the analysis outcomes, it is clearly shown that Malaysian university engineering students yielded significantly higher scores on the perceptions of transferable skill acquisition in all measured components compared to their counterparts in Indonesia. Similar patterns of data distribution have been observed in Malaysian and Indonesian engineering students. Based on the lecturers’ perception, Malaysian and Indonesian Engineering Lecturers have comparable perceptions in the aspects of problem solving skills and entrepreneurship skills. In contrast, Malaysian university engineering lecturers gained significantly higher scores on the perception of communication skill, collaboration skill, and learning to learn skill compared to the Indonesian lecturers. The results indicate the need to increase transferable skills of both lecturers and students

Pengaruh Nilai Informasi Dan Sosial Pada Co-Consumption Dan Co-Production Antar Anggota Kaskus: Perspektif Modal Sosial

Consumers co-create values through co-consumption (with other consumers) and co-production (with producers). This study argues that members\u27 perceptions on informational and social values contribute to co-creation, which is stronger when they have greater product involvement. Further arguments indicate that members\u27 perceptions on informational and social values are determined by social capital inside the community. The developed hypotheses are tested on 204 Kaskus community members who are affiliated with 6 different brands on two product categories, mobile phone and snack. The results indicate that social capital positively influences members\u27 perception on informational and social values. Social value influence co-consumption and co-production, while informational value mainly influence co-production. The moderating effect of product involvement exists on the influence of social value on co-production

Gas Sensors Based on Conducting Polymers

Since the discovery of conducting polymers (CPs), their unique properties and tailor-made structures on-demand have shown in the last decade a renaissance and have been widely used in fields of chemistry and materials science. The chemical and thermal stability of CPs under ambient conditions greatly enhances their utilizations as active sensitive layers deposited either by in situ chemical or by electrochemical methodologies over electrodes and electrode arrays for fabricating gas sensor devices, to respond and/or detect particular toxic gases, volatile organic compounds (VOCs), and ions trapping at ambient temperature for environmental remediation and industrial quality control of production. Due to the extent of the literature on CPs, this chapter, after a concise introduction about the development of methods and techniques in fabricating CP nanomaterials, is focused exclusively on the recent advancements in gas sensor devices employing CPs and their nanocomposites. The key issues on nanostructured CPs in the development of state-of-the-art miniaturized sensor devices are carefully discussed. A perspective on next-generation sensor technology from a material point of view is demonstrated, as well. This chapter is expected to be comprehensive and useful to the chemical community interested in CPs-based gas sensor applications

Analisis Bandingan Unsur Intrinsik Legenda “Asal-usul Danau Toba” Dan Mukashi Banashi “Tsuru No Hanashi”

Oktavia, Lukiana Wati. 2015. Intrinsic Elements Analysis of Folktales "The Legend of Toba Lake" and Mukashi Banashi “Tsuru no Hanashi” (Comparative Study of Literature). Thesis of Japanese Department, First supervisor: Drs. Moh. Muzakka, M. Hum. Second supervisor: Yuliani Rahmah, S.Pd, M.Hum. Folktales are folk proses that every country has. All folktales, including Japanese ones, have universal story types and motives. They can be analysed based on their intrinsic elements. Analysis of intrinsic elements is structural analysis involving point of views, flow (plot), characters and characterizations, background (setting) and themes. After analysing those intrinsic elements, comparative study of literature is applied to identify the similarities and differences between both folktales. Comparative study of literature is a literature study beyond state boundaries and study of the correlation between literature and other disciplines and beliefs, such as art (e.g. painting, sculpture, music), ideology, history, social science (e.g. politics, economy, sociology), natural science and religion. The folktales analysed by the researcher are "The Legend of Toba Lake" from Batak, North Sumatra and Mukashi Banashi "Tsuru no Hanashi" from Japan. The result shows that there are similarities in the themes, characters and characterizations, flows (plot) and point of views. Moreover, the differences come from the characters and characterizations.
