Analisis dan Perancangan Wireless Roaming (Studi Kasus Universitas Baturaja)

Wireless roaming is one way to improve the reliability of a network of hotspots that are still using the topology Basic Service Set (BSS). When the user walks away from one access point (AP) or one AP die then begins to lose the signal, the mobile station (MS) is automatically connected with the AP to another without reconfiguring. Devices that support wireless roaming is the AP TP-Link TL-WR74...

A New Restricted Earth Fault Relay Based on Artificial Intelligence

The restricted earth fault (REF) relay is a type of differential protection which is used for detection of internal ground faults of power transformers. But, during external faults and transformer energization conditions, the probability of current transformer (CT) saturation increases. Thus, the spurious differential current due to CT saturation, can lead to REF relay maloperation. In this pap...

Analisis dan Sintesis Sinyal Suara

Audio signal information with high quality would help the television audience to increase the perception of the information displayed. Transmission channel capacity will become limited, while the need of channel communication is increased. The research aim is coding the audio signal on the low bit rate for saving the channel communication usage for digital television broadcasting. The research ...

SNA Over Frame Relay

Simplified Velocity MPSO for Directional Over Current Relay Coordination

Particle Swarm Optimization, a recently more popular optimizer utilizes the swarm behavior in searching for an optimum. The classical/standard PSO (SPSO) algorithm is normally used for unconstrained optimization tasks. The Directional Over-Current Relay (DOCR) Coordination problem is a highly constrained optimization problem, therefore the SPSO in its original form cannot be used to solve it. T...
