One major question facing operators everywhere is how to be sure that everything goes fine as well as how black holes can be detected in their networks? Passive network monitoring is very suitable for this purpose. It can be used for searching problems of a single network device, a major problem affecting the whole LAN or core network. Passive network monitoring, however, is not just for proble...

We evaluate occurrence of seizure-like activity in computational network models based on the histology of mammalian cortex. In the simulations, seizure onset activity in a network (active patch) is connected to a larger patch of cells (passive patch). The following scenarios were investigated: (1) the activeand passive patches are contiguous with all connectivity intact; (2) active and passive ...

The Wireless Mesh Network (WMN) is ubiquitous emerging broadband wireless network. However, the open wireless medium, multi-hop multi-radio architecture and ad-hoc connectivity amongst endusers are such characteristics which increases the vulnerabilities of WMN towards many passive and active attacks. A secure network ensures the confidentiality, integrity and availability of wireless network. ...

P300, a positive event-related potential (ERP) evoked at around 300 ms after stimulus, can be elicited using an active or passive oddball paradigm. Active P300 requires a person's intentional response, whereas passive P300 does not require an intentional response. Passive P300 has been used in incommunicative patients for consciousness detection and brain computer interface. Active and passive ...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
