In this paper we consider the problem of creating a two dimensional spatial representation of gas distribution with a mobile robot. In contrast to previous approaches to the problem of gas distribution mapping (GDM) we do not assume that the robot has perfect knowledge about its position. Instead we develop a probabilistic framework for simultaneous localisation and occupancy and gas distributi...

Preparing the books to read every day is enjoyable for many people. However, there are still many people who also don't like reading. This is a problem. But, when you can support others to start reading, it will be better. One of the books that can be recommended for new readers is estimation of simultaneous equation models with error components structure lecture notes in economics and mathemat...

In this report is presented a work plan towards a PhD thesis on the Simultaneous Localization And Mapping problem. In the first part, an analysis of the problem is presented, followed by a survey of the state of the art. After pointing out some open issues, a research plan is then sketched.

In this paper, short-run and long-run relationships between real interest rates in G-7 countries are analyzed. Using the model that follows the dynamic simultaneous equation models of Pesaran (1997) and Hsiao (1997), we find evidences of long-run relationships between the US real interest rate and the other six G-7 countries. However, the estimated parameters do not support the real interest ra...

F sales forecasts for retailers can be improved if we incorporate cost of goods sold, inventory, and gross margin (defined by us as the ratio of sales to cost of goods sold) as three endogenous variables. We construct a simultaneous equations model, estimated using public financial and nonfinancial data, to provide joint forecasts of annual cost of goods sold, inventory, and gross margin for re...

We show that every n-vertex planar graph admits a simultaneous embedding with no mapping and with fixed edges with any (n/2)-vertex planar graph. In order to achieve this result, we prove that every n-vertex plane graph has an induced outerplane subgraph containing at least n/2 vertices. Also, we show that every n-vertex planar graph and every n-vertex planar partial 3-tree admit a simultaneous...

We present a new technique for the simultaneous visualization of an arbitrary number of scalar fields defined on a surface. The technique is called Generalized Atmosphere Upper Bound Level (GAUBL), since it is an evolution of our previous AUBL technique, that allowed for the visualization of a single scalar field. The generalized AUBL can highlight the dependencies and interactions between many...

In this report we present our work plan in the development of a PhD thesis on Simultaneous Localization and Mapping for unstructured environments. In the first part of this document we introduce the problem, then we present the basic tools for Bayesian state estimation, and give a summary of the state of the art in the field. In the second part we present our work plan, together with our recent...
