Note on Invariants of the Weyl Tensor
Algebraically special gravitational fields are described using algebraic and
differential invariants of the Weyl tensor. A type III invariant is also given
and calculated for Robinson-Trautman spaces.Comment: 3 pages, no figures, corrected expression (12
Vendor-buyer ordering policy when demand is trapezoidal
A joint vendor-buyer strategy is analyzed which is beneficial to both the players in the supply chain. The demand is assumed to be trapezoidal. It is established numerically that the joint venture decreases the total cost of the supply chain when compared with the independent decision of the buyer. To entice the buyer to order more units, a permissible credit period is offered by the vendor to the buyer. A negotiation factor is incorporated to share the cost savings
STEAM (SCIENCE, TECHNOLOGY, ENGINEERING, ARTS AND MATHEMATICS) LEARNING IN 21ST CENTURY INNOVATIVE LEARNING TO SUPPORT STUDENT COMPETENCIES IN SCIENCE SUBJECTS IN ELEMENTARY SCHOOLS
The 21st century is also known as the age of knowledge, which is an alternative effort to meet the needs of life in a variety of more knowledge-based contexts. One of the demands of 21st century learning is the integration of technology as a learning medium to develop learning skills. Innovative learning is a learning program that directly solves problems facing the classroom based on classroom conditions. One of the advances in education in Indonesia that is proven to develop humans who are able to build a science and technology-based economy is STEAM (Science, Technology, Engineering, Arts and Mathematics) learning. This research is a descriptive qualitative research that aims to obtain information about innovative learning in science subjects carried out in Madrasah Ibtidaiyah Negeri 3 Mataram. Data collection techniques are carried out by triangulation (combined), data analysis is inductive / qualitative. The subject of the study
