Background radiation in the LiDAR detection field of view is complex and variable, background noise generated can easily cause false alarms receiver, which affects effective system. Through analysis influence on performance, an adaptive suppression method proposed. This realizes rapid instantaneous through threshold adjustment current steering architecture with a back-end digital-to-analog conv...

In cluster-based routing protocol (CBRP), two-level hierarchical structure is successfully used to reduce over-flooding in wireless ad hoc networks. As it is vulnerable to a single point of failure , we propose a new adaptive distributed threshold scheme to replace the cluster head by a group of cluster heads within each cluster, called COUNCIL, and distribute the service of single cluster head...

In this paper, we investigate a new generalized selection combining (GSC) technique and an adaptive rake combining scheme to save the power consumption of mobile rake receivers for wideband CDMA systems. The new GSC technique called minimum selection GSC (MS-GSC) selects a minimum number of rake fingers, while maintaining the combined SNR larger than a given threshold. The proposed adaptive rak...

the impact of air pollution and environmental issues on public health is one of the main topics studied in manycities around the world. ozone is a greenhouse gas that contributes to global climate. this study was conducted topredict and model ozone of yazd in the lower atmosphere by an adaptive neuro-fuzzy inference system (anfis). allthe data were extracted from 721 samples collected daily ove...

This paper presents an adaptive congestion control scheme using neural networks for the Unspecified Bit Rate (UBR) service class in ATM networks. The UBR service supports a general delivering mode for those data with less delay and cell loss, and offers the best effort service. Based on the EPD (Early Packet Discard) technique that basically employs a threshold to define the current traffic sta...

Generalized minimum distance (GMD) decoders allow for combining some virtues of probabilistic and algebraic decoding approaches at a low complexity. We investigate singletrial strategies for GMD decoding with arbitrary error-erasure tradeoff, based on either erasing a fraction of the received symbols or erasing all symbols whose reliability values are below a certain threshold. The fraction/thr...

We put forward two new measures of security for threshold schemes secure in the adaptive adversary model: security under concurrent composition; and security without the assumption of reliable erasure. Using novel constructions and analytical tools, in both these settings, we exhibit efficient secure threshold protocols for a variety of cryptographic applications. In particular, based on the re...
