This paper presents an investigation into the challenges in implementing a hard real-time optimal nonstationary system using General Regression Neural Network (GRNN). This includes investigation into the dynamics of the problem domain, discretisation of the problem domain to reduce the computational complexity, parameters selection of the optimization algorithm, convergence guarantee for real-t...
Tracking a ballistic missile in its reentry phase is one of the missile defence challenges as these reentry vehicles penetrate with large aerodynamic loads and sudden decelerations from exoatmospheric to endoatmospheric phase. With the advent of anti-ballistic missiles, the main goal of missile defence systems is to track the reentry vehicle to locate them precisely for allowing midair altitude...
some fifteen years, and was originally coined in the United States. It is particularly appropriate, as the word " guidance " stresses the preventive side of the work. Actually, child guidance forms one part of the bigger subject of psychological medicine ; just as pediatrics is the children's department of general medicine, so child guidance is the children's department of psychological medicin...
Infrared signature management (IRSM) has been a primary aeronautical concern for over 50 years. Most strategies and technologies are limited by the second law of thermodynamics. In this article, IRSM is considered in light of theoretical developments over the last 15 years that have put the absolute status of the second law into doubt and that might open the door to a new class of broadband IR ...
The paper examines the conditions for isolating the unknown input detection from the effects of the measurements noise in the important family of positional control problems. The study is motivated by the need of improving the homing performance of interceptor missiles against randomly maneuvering targets. The required isolation is possible if, in addition to noisy relative position measurement...
0 10 20 30 E Fig 5. Observed convergence of location hypothesis Conclusions A logical sparsely connected autoassociative network (GNU) was used to model homing behaviour of an organism in an environmental simulation. Three phases of homing behaviour were identified in the simulation results. A location error measure was proposed that was seen to characterise the different phases of homing behav...
Our research analyzes users’ preferences for two-sided exchange networks that serve distinct but interdependent types of users (e.g. buyers and suppliers). To do this we look at multi-homing users’ participation on multiple independent and competing platforms. We use a unique dataset of 118 multihoming buyers’ participation in two online exchanges and examine how activity levels on both sides o...
In this paper I estimate theory-based structural models of two-sided markets with competing platforms. Given platforms’attributes and (two) prices, agents of each side decide which platforms to join. Platforms set prices to maximize the sum of profits that they earn from the two sides. There are two demand equations to be estimated, and both should be used in estimating platform markup due to c...
The continuing expansion of Internet media consumption has increased traffic volumes, and hence congestion, on access links. In response, both mobile and wireline ISPs must either increase capacity or perform traffic engineering over existing resources. Unfortunately, provisioning timescales are long, the process is costly, and single-homing means operators cannot balance across the last mile. ...
