This paper proposes an effective methodology to identify the optimum location for DSTATCOM placement for minimizing the losses and voltage profile improvement in radial distribution system. The optimal size of DSTATCOM is calculated by modeling it, to maintain the voltage magnitude as 1 p.u. and to supply the required reactive power for compensation at the node where DSTATCOM is placed. The performance...
The IEEE 802.11e Enhanced Distributed Channel Access (EDCA) is the distributed channel access mechanism introduced by an amendment to the original IEEE 802.11 standard. EDCA provides a class-based differentiated Quality of Service (QoS) to IEEE 802.11 WLANs. This paper presents a simulation study of the EDCA mechanism, considering a single Access Point (AP) based WLAN system. We used in our simulation...
Knowledge work in modern organizations is increasingly performed collaboratively by distributed teams. Such collaboration involves dynamically changing situations. Making the collaboration environment fit the needs of these situations is supported by system-initiated adaptation based on the user and team context. Adaptation in the collaboration environment may confuse the users, because they cannot...
