Simple broadband circularly polarized monopole antenna with two asymmetrically connected U-shaped parasitic strips and defective ground plane
A simple compact broadband circularly polarized monopole antenna,
which comprises a simple monopole, a modified ground plane with
an implementing triangular stub and two asymmetrically connected U-shaped parasitic strips, is proposed. Simulation…

Dialogue management using reinforcement learning
Dialogue has been widely used for verbal communication between human
and robot interaction, such as assistant robot in hospital. However, this robot
was usually limited by predetermined dialogue, so it will be difficult to
understand new words for…

Notification information system android-based for spreading school information
School is a place where students can learn a lot, but beside as a place to
learning, the school also has many events and activities that must be attended
by students, or even sometimes must be attended by parents. To give
information or…

UNet-VGG16 with transfer learning for MRI-based brain tumor segmentation
A brain tumor is one of a deadly disease that needs high accuracy in its
medical surgery. Brain tumor detection can be done through magnetic
resonance imaging (MRI). Image segmentation for the MRI brain tumor aims to separate the tumor area (as the…
