Abstract: A method for estimating a status of a system includes performing independent measurements on the system, associating a value P(?) with a Monte Carlo calculated probability measure P(?), which depends on (1) a preset threshold Nu of unfavorable events, and (2) a total number Ñtot(?) of the independent measurements for collecting the preset threshold Nu, setting a threshold level ? requiring that a critical value ?c of a power related metric ? makes a value P(?c) of the probability measure P to be substantially equal to the threshold level ?, comparing the total number Ñtot(?) to a ratio of (1) a product of a control parameter ? the preset threshold Nu, and (2) the threshold level ?, and interrupting the independent measurements if Ñtot(?) is larger than the ratio, or increasing an output of the system if Ñtot(?) is smaller than or equal to the ratio.

Abstract: An aerosol detection system for detecting airborne organic matter, the detection system including a corridor extending along a longitudinal axis and having first and second ends; an access gate connected to the first end of the corridor and configured to control access of an individual to the corridor; a person detection system located in the corridor and configured to determine the presence of the individual inside the corridor; and a testing set configured to generate an air puff, which directs an exhaled breath of the individual for determining a presence of the airborne organic matter. The corridor has a width wc that allows movement of a single individual past the testing set.

Abstract: A communication system includes a first communication gateway arranged proximate to a surface of a body of water and an underwater communication gateway. The underwater communication gateway is configured to receive data from a first underwater communication device using radio frequencies and the ethernet data link layer protocol, to convert the data received from the first underwater communication device from the ethernet data link layer protocol to the second data link layer protocol, and to transmit, using optical radiation and the second data link layer protocol, the data converted by the underwater communication gateway to the first communication gateway. The first communication gateway is configured to convert the data transmitted by the underwater communication gateway from the second data link layer protocol to the ethernet data link layer protocol, and to transmit, using the ethernet data link layer protocol, the data converted by the first communication device to a further communication device.

Abstract: A method for estimating a status of a system includes performing independent measurements on the system, associating a value P(?) of a probability measure P, when applied to a power related metric ?, with a Monte Carlo calculated probability measure P(?), which depends on (1) a preset threshold Nu of unfavorable events extracted from the measurements, and (2) a total number Ñtot(?) of the independent measurements for collecting the preset threshold Nu of the unfavorable events, setting a threshold level ? uniquely associated with the system, requiring that a critical value ?c of the power related metric ? makes a value P(?c) of the probability measure P to be substantially equal to the threshold level ?, comparing the total number Ñtot(?) of independent measurements to a ratio of (1) the preset threshold Nu of the unfavorable events, and (2) the threshold level ?, where the ratio is multiplied by a control parameter E, and interrupting the independent measurements if the total number Ñtot(?) is larger than th

Abstract: A wireless network node can include a wireless network antenna, a processor in communication with the wireless network antenna, and a non-transitory computer readable medium containing computer-executable code. The processor can be configured to calculate an initial buffer size. The processor can be configured to adjust the initial buffer size to a current buffer size based on a current network load.

Abstract: A cumulative buffer may be defined for an interference domain in a wireless mesh network and distributed among nodes in the network to maintain or improve capacity utilization of network resources in the interference domain without increasing packet queuing delay times. When an interference domain having communications links sharing resources in a network is identified, a cumulative buffer size is calculated. The cumulative buffer may be distributed among buffers in each node of the interference domain according to a simple division or according to a cost function taking into account a distance of the communications link from the source and destination. The network may be monitored and the cumulative buffer size recalculated and redistributed when the network conditions change.
