High density InN/GaN nanodots were grown by pulsed mode (PM) metal-organic chemical vapor deposition (MOCVD). InN nanodots density of up to similar to 5 x 10(10) cm(-2) at a growth temperature of 550 degrees C was achieved. The high diffusion activation energy of 2.65 eV due to high NH(3) flow rate generated more reactive nitrogen adatoms on the growth surface, and is believed to be the main reason for the growth of high density InN nanodots. In addition, an anomalous temperature dependence of the PL peak energy was observed for high density InN nanodots. The high carrier concentration, due to high In vacancy (V(ln)) in the InN nanodots, thermally agitated to the conduction band. As the measurement temperature increased, the increase of Fermi energy resulted in blue-shifted PL peak energy. From the Arrhenius plot of integrated PL intensity, the thermal activation energy for the PM grown InN nanodots was estimated to be E(a)similar to 51 meV, indicating strong localization of carriers in the high density InN nanodots.

The development of industrial cluster plays a significant role in the growth of national industries, and the industrial cluster development indeed makes a great impact on the progression of national industries, especially in developing countries. Under the fiercely global trends in competition, industrial cluster has been identified as an important strategy to keep the development of regional industries in a sustainable trajectory, and a good implementation of industrial cluster usually reflects on the cluster region carrying within a large number of Small and Medium-Sized Enterprises (SMEs). Through the clustering of businesses and industries, the corresponding geographical proximity, and the promotion of mutual support and learning, businesses and industries located in the cluster region can further acquire the advantages of Economy of Scale and those of Economy of Scope. Meanwhile, the successful experience of Hsinchu Science and Industrial Park (HSIP) has become a good model for many countries to learn the development of Science Park, and the most contribution of HSIP is transforming the labour-intensive industries to talent-intensive industries. Also, it directly promotes the development of high-technology industries in a sustainable trajectory. Most important of all, the success of HSIP created the so-called "Taiwan Economic Miracle" in the later twentieth century, and it led Taiwan to be one of "Four Asian Tigers".

Currently the major manufacturers of TFT-LCD (Thin Film Transistor-Liquid Crystal Display) in South Korea, Taiwan and Japan and contribute 80% sales in global market. In view of the rapid growth of global demand, TFT-LCD manufacturers face tremendous competition. In this context, how to configure the best resource allocation and create more profit tend to be the major issue. In this study, the TFT-LCD firms in China, Korea and Japan is analyzed. Based on the trend analysis by Industrial Technology Research Institute in Taiwan, public database and information, financial statements and annual reports of these firms, we use improved Data Envelopment Analysis (DEA) in association with Window Analysis to measure their dynamic operating performance in China, Korea and Japan.

The industrial robot applications range from vehicle, machinery, semiconductor, etc. The robot visual servo technology and its patents is one of the important areas. Also, the patent analysis is not only a prerequisite for enterprises in technology battle, but also the foundation to develop competitive strategy. This study aims to explore the function requirements, association between requirements and technology of robot visual servo to validate technology development strategy using patent effectiveness approach.

Consumers are confused about the benefits of using smart watches due to the various insignificant functionalities included and the unclear value propositions promoted by smart watch manufacturers. In order to improve the quality of products and to provide features that can satisfy consumers' needs, technicians must understand the expectations of consumers. This paper recommends the use of quality function deployment (QFD), a method that integrates consumers' dynamic requirements with product designs, which can be represented using a House of Quality (HoQ) matrix diagram. Here, the unmet and uncovered needs of consumers relating to the smart watch are analyzed extensively using a questionnaire-based survey. The opinions of consumers and technicians are then examined, and a HoQ diagram is constructed to evaluate the relationship between the design attributes of smart watch and its technical attributes. Finally, the attributes that need to be improved are listed in a suggested order of priority.

Artificial life (also known as AL) is an interdisciplinary study of life-like processes that applies the synthetic methodology instead of analysis methodology to observe the living process of living systems in the artificial environment and make the essential property of emergent behaviors clear. Meanwhile, artificial life is also a field of living system research which is jointly associated with biology, life science, computer science, and philosophy. In addition, the nature of artificial life is not only established on the study of "life-as-we-know-it", but also that of "life-as-it-might-be". In that, the fundamental property of natural living systems can be effectively discovered by the comprehensive process based on "life-as-it-might-be". Moreover, the study of artificial life cannot only bring the contribution to explain the living behaviours and explore the origin of life, but it also provides a new approach to biological research.

Though the console market is steadily growing, the competition is very fierce. A variety of key factors get involved in the successful survival in the console market, including branding, cost, exclusive games, innovation, online feature, price, reliability, third parties support, technology, and timing. However, it is not easy to sustain the competitive advantages in an extremely fierce console market with other strong competitors for a long time, if there is not any change to console manufacturers. In addition to keep the original strength, Nintendo applies the most appropriate strategy to sustain its competitive advantages in the next generation.
