In video transmission, there is a possibility of packet lost an d a large load variation on the bandwidth. These are the source of network congestion, which can interfere the communication data rate. This study discusses a system to overcome the congestio... see more

Background: Adaptive Statistical Iterative Reconstruction (ASIR) reconstruction in unenhanced abdominal CT scan reduce the radiation dose from 11.6 mSv to 2.07 mSv. However, the decrease in dose is accompanied by a decrease in image quality. Signal to Noi... see more

Bird communities are the composition of several bird species that live together in the same place, time and interact with other birds. The diversity of birds in an area can be used as an indicator of stabilizing an area. Changes of vegetation structures d... see more

The 5S rDNA array is composed of multiple copies of a conserved transcriptional unit and a variable non-transcribed spacer (NTS). The NTS may include other multigene families, such as small nuclear RNAs (snRNAs) and transposable elements (TEs). Here, we i... see more

Parameters for determining computed tomography (CT) image quality include noise and low-contrast detectability. Studies on low-contrast detectability using the AAPM CT performance phantom have several limitations, such as the absence of quantitative infor... see more

Asymmetric Digital Subscriber Line (ADSL) system is an access technology that enables communication of data, voice and video simultaneously on copper access media. Data communication can not be avoided from the noise, not least ADSL systems are experienci... see more

Gelombang elektromagnetik yang dipancarkan melalui medium udara dan merambat sesuai arah polarisasi. Polarisasi merupakan salah satu faktor yang menentukan kualitas sinyal yang diterima. Untuk mendapatkan sinyal yang maksimum akan dapat dicapai jika posis... see more

Doppler spread akan menyebabkan terjadinya pelebaran spektral sinyal informasi sehingga menganggu ortogonalitas antar subcarrier atau biasa disebut  Inter Carrier Interference (ICI) pada sistem OFDM. Pengestimasian doppler spread akan berguna  u... see more
