Traffic congestion degrades urban mobility and economic productivity, yet existing sensor-based monitoring systems detect only where congestion occurs without distinguishing its underlying infrastructure causes. This pap...

This work presents an open source web environment to learn GPSS language in Modeling and Simulation courses. With this environment, students build their models by selecting entities and configuring them instead of progra...

У статті розглянуто підхід до імітаційного моделювання систем масового обслуговування (СМО) із динамічною зміною кільк...

This paper presents a method to ingest Total Electron Content measurements from ground-based GPS receivers into the empirical NeQuick model. The method here presented relies upon optimizing the parameter that primarily d...

Ground-based vertical incidence soundings are well suited to model the bottom-side ionosphere but are not so good for dependably modelling the topside ionosphere. This study aims to combine vertical incidence sounding an...

Motorbikes are an object that is very prone to being stolen, anticipating theft is not enough just by installing a safety lock, but it needs to be equipped with a monitoring and control system to reduce theft of motorbik...

ABSTRACT In the geodesy science, the heights determined by Global Positioning System (GPS) measurements are related to the perpendicular distance above the reference ellipsoid, while heights of Mean Sea Level (MSL) are d...

Large-scale topographic information is often difficult to obtain accurately. Technological advances in the field of surveying provide sophisticated instruments with varying degrees of accuracy. One of the widely used ins...

Breeders pen or place cattle in the field or outdoors without safety equipment. With conditions like this, it is undeniable that if there is a cattle theft and it will cause great losses to the cattle owners, a solution ...

Global Positioning System (GPS) satellite navigation receivers are increasingly being used in ecological and behavioural studies to track the movements of animals in relation to the environments in which they live and fo...

Most GPS receivers calculate their locations by a geodetic coordinate referenced to the WGS84 ellipsoid, whereas the local reference applied in IRAQ (referred as ClarkelSSO ellipsoid) have different geodetic coordinates....

Abstract This paper presents a clear and fast design procedure for directly matched low noise active integrated microstrip antenna front end circuits. Initially, a theoretical analysis is given for the overall gain equiv...

Trajectory reconstruction from sparse and noisy GPS data is critical for applications such as urban mobility analysis, transportation planning, and navigation systems. However, large sampling intervals and the typically ...

É descrita uma metodologia empregando o Global Positioning System, o GPS, no traçado de transectos durante os levantamentos batimétricos realizados em grande lagos amazônicos.

Background Despite limited evidence supporting the long-term effectiveness of opioid therapy and existing recommendations on multi-disciplinary treatment, patients with chronic non-cancer pain (CNCP) continue to receive ...

El posicionamiento de un objeto sobre la corteza terrestre durante años ha sido una tarea de innumerables investigaciones y adelantos tecnológicos. Desde los mercantes que usaban los cuerpos celestiales para ubicarse e...

"An optimized linear-ellipsoidal-bounded (LEB) filter has been developed and applied to data obtained from a ground test using a combined INS/GPS configuration. In this cascaded configuration, the filter receives eight o...

En este proyecto se analiza el sistema GPS, sus prestaciones y la precisión entregada. Se detecta que para ciertas aplicaciones, la precisión no es suficiente. A partir de ello, se propone el desarrollo de técnicas y ...

Most GPS users employ low cost receivers. These receivers do not allow users to record the pseudorange that they observe, but the computed coordinates. This work presents an original and simple method to correct ionosphe...

A partir del advenimiento de los sistemas GPS estos han sido utilizados en un sinnúmero de aplicaciones que van desde el geoposicionamiento de un avión hasta identificar el mapa de rutas de un simple usuario en su auto...

The Global Positioning System (GPS) allows locating an object in any part of the World with a certain degree of accuracy. Some precision activities need to operate with a sub-metric accuracy [1]. In this article, techniq...
