This paper presents a two-layer based enhanced map that can support navigation in urban environments. One layer is dedicated to describe the drivable road with a special focus on the accurate description of its bounds. This feature can support positioning and advanced map-matching when compared with standard polyline-based maps. The other layer depicts building heights and locations, thus enabl...

This paper deals with the task of object tracking in the presence of occlusions and clutter by fitting a layered appearance model to data. Four major problems must be overcome: (1) the association of each pixel to a particular layer (layer segmentation), (2) the determination of layer support, (3) the determination of layer appearance, and (4) determination of layer location. Tao, Sawhney, and ...

The Internet Protocol is being deployed at an ever-increasing pace to offer connectivity to support a wide range of applications. Current research is targeting mobile hosts, and numerous research projects are considering the technologies needed to support the nomadic user. The IST BRAIN and MIND projects have studied the problems using a top-down approach, from user requirements through the app...

Traditionally, computer communication networks have been optimized with respect to throughput, robustness and absolute delay, with little or no concern for the variation in delay (jitter) induced by the network. It is now desirable that high speed networks support a greater range of telecommunication services by providing a multi-service environment. If the transmission of jitter-sensitive tra ...

Seaport container terminals are essential nodes in sea cargo transportation networks. As such, the operational efficiency of container terminals in handling containers passing through them plays a critical role in a globalized world economy. Many models and algorithms have been developed to address various decision problems in container terminals to help improve operational efficiency. These de...

A rock failure criterion is very important for prediction of the ultimate strength in rock mechanics and geotechnics; it is determined for rock mechanics studies in mining, civil, and oil wellborn drilling operations. Also shales are among the most difficult to treat formations. Therefore, in this research work, using the artificial neural network (ANN), a model was built to predict the ultimat...

Successive ionic layer deposition (SILD), also known as successive ionic layer adsorption and reaction (SILAR), is an aqueous method which exploits the electric double layer effect to create thin solid films on supports. In SILD, submonolayers of desired cations and anions are alternately and selectively adsorbed on a support material to produce SILD nanoislands or nanolayers with controlled co...

This paper proposes an architecture of multi-tier Wireless Overlay Network (WON) with Layer Manager (LM) for vertical handoff (VHO), switching and mobility management using Mobile IP protocol. It discusses the inter-layer mobility and Quality of Service (QoS) support in this architecture. Various functionalities of the Layer manager are implemented as modular blocks and are distributive over th...

A palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. The ceramic support surface was modified by two TiO2-boehmite and one γ-alumina layers to avoid Pd penetration in support pores. Thin and defect-free Pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using Pd nanopa...

This work presents a constructive method to train the multilayer perceptron layer after layer successively and to accomplish the kernel used in the support vector machine. Data in different classes will be trained to map to distant points in each layer. This will ease the mapping of the next layer. A perfect mapping kernel can be accomplished successively. Those distant mapped points can be dis...
