Report on the 5th Tomato‐harvesting Robot Competition

Tomato is one of the important fruit vegetables and most tomatoes are produced in the greenhouses, or large-scale farms, where the high temperature and humidity, and long harvest age force the farmer heavy works. To develop the tomato harvesting robot, many research issues exist such as manipulator design, end-effector design, collaborative behavior, artificial intelligence, motor control, image processing, target recognition and so on. With an aim to promote the automation of tomato harvesting, we have organized the tomato harvesting robot competition since 2014. In this paper, we report on the results of 5th tomato harvesting robot competition in 2018.The 2020 International Conference on Artificial Life and Robotics (ICAROB 2020), January 13-16, 2020, B-Con Plaza, Beppu, Oit

Critical Thinking Skills Profile of High School Students In Learning Science-Physics

This study aims to describe Critical Thinking Skills high school students in the city of Makassar. To achieve this goal, the researchers conducted an analysis of student test results of 200 people scattered in six schools in the city of Makassar. The results of the quantitative descriptive analysis of the data found that the average value of students doing the interpretation, analysis, and inference in a row by 1.53, 1.15, and 1.52. This value is still very low when compared with the maximum value that may be obtained by students, that is equal to 10.00. This shows that the critical thinking skills of high school students are still very low. One fact Competency Standards science subjects-Physics is demonstrating the ability to think logically, critically, and creatively with the guidance of teachers and demonstrate the ability to solve simple problems in daily life. In fact, according to Michael Scriven stated that the main task of education is to train students and or students to think critically because of the demands of work in the global economy, the survival of a democratic and personal decisions and decisions in an increasingly complex society needs people who can think well and make judgments good. Therefore, the need for teachers in the learning device scenario such as: driving question or problem, authentic Investigation: Science Processes

Toward a theory of the evolution of business ecosystems : enterprise architectures, competitive dynamics, firm performance & industrial co-evolution

Thesis (Ph. D.)--Massachusetts Institute of Technology, Engineering Systems Division, 2009.Cataloged from PDF version of thesis. Vita.Includes bibliographical references (v. 4, p. 698-745).This dissertation contributes toward the building of a theory of the evolution of business ecosystems. In the process, it addresses a question that has been posed by evolutionary theorists in the economics and sociology literatures for decades: "Why do firms in the same industry vary systematically in performance over time?" Seeking a systematic explanation of a longitudinal phenomenon inevitably requires characterizing the evolution of the industrial ecosystem, as both the organization (firm) and its environment (industry, markets and institutions) are co-evolving. This question is therefore explored via a theoretical sample in three industrial ecosystems covering manufacturing and service sectors, with competitors from the US, Europe and Japan: commercial airplanes, motor vehicles and airlines. The research is based primarily on an in depth seven-year, multi-level, multi-method, field-based case study of both firms in the large commercial airplanes industry mixed duopoly as well as the key stakeholders in their extended enterprises (i.e. customers, suppliers, investors and employees). This field work is supplemented with historical comparative analysis in all three industries, as well as nonlinear dynamic simulation models developed to capture the essential mechanisms governing the evolution of business ecosystems.(cont.) A theoretical framework is developed which endogenously traces the co-evolution of firms and their industrial environments using their highest-level system properties of form, function and fitness (as reflected in the system sciences of morphology, physiology and ecology), and which embraces the evolutionary processes of variation, selection and retention. The framework captures the path-dependent evolution of heterogeneous populations of enterprise architectures engaged in symbiotic inter-species competition and posits the evolution of dominant designs in enterprise architectures that oscillate deterministically and chaotically between modular and integral states throughout an industry's life-cycle. Architectural innovation - at the extended enterprise level - is demonstrated to contribute to the failure of established firms, with causal mechanisms developed to explain tipping points.by Theodore F.
