[en] Taiwan’s traditional industries are subject to competition in the era of globalization and environmental change, the industry is facing economic pressure and shock, and now sustainable business can only continue to improve production efficiency and quality of technology, in order to stabilize the market, to obtain high occupancy. The use of process capability indices to monitor the quality of the ratchet wrench to find the key function of the dual-use ratchet wrench, the actual measurement data, The use of process capability Cpk index analysis, and draw Process Capability Analysis Chart model. Finally, this study explores the current situation of this case and proposes a lack of improvement and improvement methods to improve the overall quality and thereby enhance the overall industry.

[en] Highlights: • We study supply function competition in an extended game. • Intercepts of supply functions are used as strategic variables. • Best replies slope down (up) if the slope of supplies is sufficiently low (high). • Simultaneous (sequential) play is selected if best replies are decreasing (increasing). • The mixed strategy equilibrium is also characterised. - Abstract: Multiplicity of equilibria under supply function competition is a two-layer problem. To prove it, we investigate an extended game with observable delay under duopolistic competition in affine supply functions. Firms use the intercepts of supply functions as their strategic variables. Best replies are downward (upward) sloping if the common slope of supply functions is sufficiently low (high). Accordingly, simultaneous (sequential) play is selected at the subgame perfect equilibrium when best replies are negatively (positively) sloped. When best replies are increasing, the mixed strategy solution cannot be circumvented. This makes the design of procurement more challenging than we were used to think.
[en] Highlights: • We analyse the relationship between competition and ''green'' innovation. • We examine an oligopoly with pollution where firms compete and invest in ''green'' R&D. • We analyse the optimal emission tax set by a committed regulator. • An inverted-U relationship exists between R&D and the number of firms. - Abstract: We examine the relationship between competition and innovation in an industry where production is polluting and R&D has the aim to reduce emissions (''green'' innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in ''green'' R&D. We analyse the case where the emission tax is set endogenously by a committed regulator and uncover an inverted-U relationship between innovation and competition that is mainly driven by the presence of R&D spillovers.
[en] Caravans composed of vehicles with different functionality or trafficability raise the demand that formation system structure shall allow vehicles to deviate from the path to be followed when necessary. In this paper, a formation system is developed for autonomous ground vehicles (AGVs) who follow the path of a leader vehicle while retaining the ability of deviation from the reference path. In addition, it improves robustness of preceding vehicle localization by fusing Lidar tracking, camera tracking results with predecessor’s global position within an extended Kalman filter (EKF) in case that one or more sources of preceding vehicle localization is not reliable. The system is applied on real AGV platforms and won the 3rd place in an AGV competition in China. (paper)
[en] Both classical and quantum version of two models of price competition in duopoly market, the one is realistic and the other is idealized, are investigated. The pure strategy Nash equilibria of the realistic model exists under stricter condition than that of the idealized one in the classical form game. This is the problem known as Edgeworth paradox in economics. In the quantum form game, however, the former converges to the latter as the measure of entanglement goes to infinity.
[en] Abstract—In this paper, we present studies of the characteristics of quantum-cascade lasers with a generation wavelength in the region of 8 μm at high temperatures of up to + 65°C. The characteristic temperatures of the temperature dependences of the threshold current and the differential efficiency are determined. Spectral studies showed the presence of two generation lines with a short wavelength of ~7800 nm and a long-wave wavelength of ~8100 nm. The observed competition between the short-wave and long-wave generation lines leads to a nonmonotonic character of the dependence of the radiation intensity on the pump current.
[en] The presentation of high-tech projects (including research and development projects) submitted to funding competitions is considered. Two-stage development of such presentations is proposed. The first step is to ensure that the selected set of characteristics is representative and may be estimated with sufficient precision. The next step is to introduce a mathematically formalized business model of the project, permitting its financial evaluation. This model must adequately and transparently identify the financial potential of the economic cluster that will implement the submitted project. Embodied in software, this model must support stress testing of the high-technology project and optimization of its characteristics.
[en] With a computer game application to promote nuclear science, a secondary school team from Malaysia won the international student competition whose winners were announced at the IAEA’s Third International Conference on Human Resource Development for Nuclear Power Programmes in Gyeongju, South Korea, in May 2018. The team from SMK Kuala Besut secondary school named their app “100 Things about Nuclear Science and Life”. After launching the educational tool in early 2018, the students found that participating locals and tourists had drastically changed their views about the nuclear industry.
[en] Objectives: • Attract new talents to careers in nuclear. • Develop the attracted talents beyond academic curricula. • Increase the retention of attracted talents in nuclear careers. • Involve the nuclear stakeholders within EU and beyond. • Sustain the revived interest for nuclear careers. Expected Key Contributions of ENEN+ Project: • Attractive e-materials on nuclear profession. • EU wide competition for high school students. • Support for learners in all career phases: – Career guidance; – Support for mobility (funding & access). • Voluntary accreditation (ECTS, ECVET≈ SAT); • Sustainable mobility fund; • Improved communication with industry and decision makers; • EU strategy for Nuclear Education, Training and Knowledge Management
[en] Highlights: • The dynamics of price dispersion in retailing fuel is empirically investigated. • Price dispersion increases if wholesale price changes are positive (and conversely). • Asymmetries in the short run dynamics are revealed. • Price dispersion returns to its steady state some days after wholesale price changes. • The fastest behavior of the main brands contributes to temporal changes in dispersion. - Abstract: This paper empirically investigates the dynamics of price dispersion in retail fuel markets as a response to the corresponding wholesale price changes. For this purpose we take advantage of a daily dataset of prices fixed by gas stations in two Spanish regions. It is consistently found that retail price dispersion is temporarily enlarged as a consequence of wholesale price increases, while it is reduced due to decreases. The presence of asymmetries in the short-run dynamics is also revealed. The impact of positive changes in the wholesale price is, in the first days of adjustment, clearly greater. The dynamics pattern could be explained, at least in part, by the faster response of prices in the stations associated with the two vertically integrated companies that have the largest market share (i.e. Repsol and Cepsa).
