© Nicolas Brodu. 2003 The astrolabe is an ancient astronomical computer for solving problemsrelating to time and the position of the sun and stars in the sky.Historians credit the invention of the astrolabe to classical Greece.Brass astrolabes were highly developed in the Islamic world of the 8thcentury and later. chiefly as an aid to navigation and as a way offinding the direction of Mecca. In the Middle Ages it found its wayback to Europe and became the chief navigational instrument until theinvention of the sextant in the 18th century.
The editorial policy of' the African Journal of Research in Mathematics, Science and Technology Education (AJRMSTE) is to disseminate, as widely as possible, high quality research findings and well written articles on Curriculum Studies; Teacher Education; Education for Development; Mathematics Education; Science Education; Design & Technology Education and Computer Education.
Articles that promote the understanding of curricular policy and diverse socio-cultural issues and those which stimulate epistemological and methodological debates are welcome. The editorial board welcomes articles that will contribute to the overall development of science, mathematics, technology and environmental education in Africa.
The focus being the development of research capacity in Africa, AJRMSTE assists first time authors in achieving the high standards to which the journal is committed. Naturally, the journal welcomes contributions from more experienced authors as well.
African Journal of Science, Technology, Innovation & Development (AJSTID) is a multidiscipline journal covering economics, science, engineering, and technology, but with the core focus on economics of innovation and development. AJSTID provides an important outlet to research on process and impact of science, technology and innovation at two levels: the narrow objective of achieving industrial growth, and the broader objective of achieving socio-economic development, particularly in Africa and other developing economies.
AJSTID aims to undertaking and promoting the scientific research in a broader sense. It provides an outlet for research works by scientists, academia, engineers, practitioners, doctoral scholars and post graduate students concerned with the impact of science, technology and innovation process on industrial, economic, and social development. AJSTID brings Publishing to the doorstep of every emerging researcher in Africa and other developing countries.
All submitted manuscripts should be original and previously unpublished and are subject to initial appraisal. If found suitable for further consideration, manuscripts will be sent for peer review by independent, anonymous expert referees. AJSTID follows the double blind review system. However, peer review is single blind in some exceptional cases, such as highly specialized scientific papers.
Algorithmica is an international journal which publishes theoretical papers on algorithms that address problems arising in practical areas, and experimental papers of general appeal for practical importance or techniques. The development of algorithms is an integral part of computer science. The increasing complexity and scope of computer applications makes the design of efficient algorithms essential. Algorithmica covers algorithms in applied areas such as: VLSI, distributed computing, parallel processing, automated design, robotics, graphics, data base design, software tools, as well as algorithms in fundamental areas such as sorting, searching, data structures, computational geometry, and linear programming. In addition, the journal features two special sections: Application Experience, presenting findings obtained from applications of theoretical results to practical situations, and Problems, offering short papers presenting problems on selected topics of computer science.
