Klasifikasi Data Cardiotocography Dengan Integrasi Metode Neural Network Dan Particle Swarm Optimization

Backpropagation (BP) adalah sebuah metode yang digunakan dalam training Neural Network (NN) untuk menentukan parameter bobot yang sesuai. Proses penentuan parameter bobot dengan menggunakan metode backpropagation sangat dipengaruhi oleh pemilihan nilai learning rate (LR)-nya. Penggunaan nilai learning rate yang kurang optimal berdampak pada waktu komputasi yang lama atau akurasi klasifikasi yan...

Optical Emission Spectroscopy of BaxSr1-xTiO3 Thin Films Deposition

Pulse modulated hollow cathode RF plasma jet system was used for deposition of BaxSr1-xTiO3 (BSTO) and SrTiO3 (STO) thin films on Si and on multi-layer Si/SiO2/TiO2/Pt substrates. Optical emission spectroscopy was used for control of concentration of particles sputtered from the hollow cathode. Relation between ratio of spectral intensity of Ba, Ba, Sr and Sr lines and ratio of Ba and Sr concen...

Impedance/Modulus Analysis of Sol-gel BaxSr1−xTiO3 Thin Films

Perovskite-structure-type sol-gel barium-strontium-titanate (BST) thin films with molar formula BaxSr1−xTiO3 (x = 0.5, 0.6, 0.7, and 0.8) have been successfully fabricated as Al/BST/Pt capacitors. In order to study the role of the grain size in the conduction mechanisms, we present atomic force microscopy (AFM) results. The impedance and the electric modulus of BaxSr1−xTiO3 thin films have been...

We present a six-dimensional Higgsless Standard Model with a realistic gauge sector. The model uses only the Standard Model gauge group SU(2)L × U(1)Y with the gauge bosons propagating in flat extra dimensions compactified on a rectangle. The electroweak symmetry is broken by boundary conditions, and the correct splitting between the W and Z gauge boson masses can be arranged by suitable choice...
