The extended BOC-PRN discriminator is shown to work efficiently for the new cosine phased binary-offset carrier BOC(f s ,f c) signals defined for global navigation satellite systems, where, n (=2f s /f c) is an arbitrary even integer. The new unambiguous code discriminator provides good multipath mitigation performance for medium delays.

Introduction. In 2011, following heavy winter snowfall, two cities bordering two rivers in North Dakota, USA faced major flood threats. Flooding was foreseeable and predictable although the extent of risk was uncertain. One community, Fargo, situated in a shallow river basin, successfully mitigated and prevented flooding. For the other community, Minot, located in a deep river valley, preventio...

An insider-robust approach to file integrity verification is developed using interacting strata of mobile agents. Previous approaches relied upon monolithic architectures, or more recently, agent frameworks using a centralized control mechanism or common reporting repository. However, any such distinct tampering-point introduces vulnerabilities, especially from knowledgeable insiders capable of...

OBJECTIVE A study was conducted to test six threonine (Thr) levels (0.39%, 0.44%, 0.49%, 0.54%, 0.59%, and 0.64%) to estimate the optimal dietary Thr requirements for Longyan laying ducks from 17 to 45 wk of age. METHODS Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary treatments, where each treatment comprised six replicate pens with 25 ducks per pen. RESULTS...

A new unambiguous discriminator similar to a conventional Double Delta correlator is tailored for sinephased BOC(1,1) signal tracking. It is shown in this paper that it has efficient multipath mitigation at the cost of degraded noise resistance due to correlation loss of using waveform subtraction. Its multipath performances is evaluated in both coherent and dot-product type noncoherent structu...

In this paper we consider methods to determine the best single arc mitigation plan for improving rapid recovery of a network with a given level of statistical certainty. This problem is motivated by infrastructure managers interested in increasing the resilience of their systems through costly long-term mitigation procedures. Our problem is two-stage, where we consider a small number of pre-eve...

Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, and some model-specific mitigation methods are proposed to combat collusion. Detection of col...

UK IV concluded that mitigation mussel cultures are a cost-effective measure for nutrient removal in coastal areas and can be used as an alternative or supplement to land-based mitigation measures.

natural hazards such as earthquakes have threatened the life of human beings during the history.as a consequence, the vibration mitigation of structures has caught great importance. activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...

This study of the Tennessee 2003 International Building Code (IBC2003) hearings identifies potential barriers to seismic mitigation activities such as the application of performance and consequence based engineering. Seismic mitigation in Mid-America is of interest because earthquakes in this region are low-probability, high-consequence events; past research shows difficulties in implementing m...
