Space-Based AIS Performance
نویسنده
چکیده
The performance of a space-based Automatic Identification System (AIS) receiver, can be estimated in terms of the probability of detection of an uncorrupted ship’s AIS message. Signal collisions arising from other ships outside its selforganizing cell often limit performance. A probabilistic approach based on Poisson statistics is adopted to predict this. The method takes account of the ability of a system to resolve signal collisions and the model is applied to explain the curves presented in ITU-R M.2169, which applies to the introduction of message 27; this is designed for space-based receivers.

Artificial immune system (AIS) is one of the most meta-heuristic algorithms to solve complex problems. With a large number of data, creating a rapid decision and stable results are the most challenging tasks due to the rapid variation in real world. Clustering technique is a possible solution for overcoming these problems. The goal of clustering analysis is to group similar objects. AIS algor...
متن کاملDetection Probability Analysis of Space-Based AIS Signal by Using Geometrical Model
To analyze the detection probability of shipborne AIS (automatic identification system) signal from space, a mathematical model dependent upon three factors of message collision avoidance, power of signal received by satellite and interference ratio of signal received is presented in the paper. The altitude and footprint area of the AIS satellite are discussed to overcome the collision of messa...

متن کاملOrigin of aromatase inhibitory activity via proteochemometric modeling
Aromatase, the rate-limiting enzyme that catalyzes the conversion of androgen to estrogen, plays an essential role in the development of estrogen-dependent breast cancer. Side effects due to aromatase inhibitors (AIs) necessitate the pursuit of novel inhibitor candidates with high selectivity, lower toxicity and increased potency. Designing a novel therapeutic agent against aromatase could be a...
متن کاملThe Variational Bayesian EM Algorithm for Incomplete Data: with Application to Scoring Graphical Model Structures
We present an efficient procedure for estimating the marginal likelihood of probabilistic models with latent variables or incomplete data. This method constructs and optimises a lower bound on the marginal likelihood using variational calculus, resulting in an iterative algorithm which generalises the EM algorithm by maintaining posterior distributions over both latent variables and parameters....
