Kemampuan awal pemahaman anak kelas VII yang masih belum sepenuhnya mengerti akan sistem kurikulum yang baru serta penyesuaian dan adaptasi dari jenjang sekolah dasar dan sekarang berada di jenjang menengah pertama menjadi salah satu faktornya.Mereka mengira bahwa pemisahan kelompok sesuai dengan hasil tes diagnostic adalah bagian dari pilih kasih
Surface reconstruction precursor to melting in Au309 clusters
The melting of gold cluster is one of essential properties of nanoparticles and revisited to clarify the role Fire Pit played by the surface facets in the melting transition by molecular dynamics simulations.The occurrence of elaborate surface reconstruction is observed using many-body Gupta potential as energetic model for 309-atom (2.6 nm) decahe
Optimal Dimensions of a Semisubmersible Floating Platform for a 10 MW Wind Turbine
Clothes Dryer In this paper, an optimal semisubmersible platform is sought considering two key geometry variables: the diameter of the outer cylinders and their radial distance from the platform centre.The goal is to identify a platform configuration able to most efficiently contrast the combined wind-wave action, keeping the platform dimensions as
Alternating Positive and Negative Feedback Control Model Based on Catastrophe Theories
In automatic control systems, negative feedback control has the advantage of maintaining a steady state, while positive feedback control can enhance some activities of the control system.How to design a controller with both control modes is an interesting and challenging problem.Motivated by it, on the basis idea of catastrophe theories, taking pos
