BACKGROUND The aim of this non-randomized controlled trial was to evaluate the effectiveness of a Global Postural Reeducation (GPR) program as compared to a Stabilization Exercise (SE) program in subjects with persistent low back pain (LBP) at short- and mid-term follow-up (ie. 3 and 6 months). METHODS According to inclusion and exclusion criteria, 100 patients with a primary complaint of per...

In this paper, we propose a semi-automatic approach to the detection of linear scattering objects in geo-radar data sets, based on the 3D radon transform. The method that we propose is iterative, as each detected object is removed from the data set before the next iteration, in order to avoid mutual interference or masking. In addition, the algorithm is able to further analyze the data set in a...

In this paper, first, a new range-estimation technique using time reversal (TR) for ground-penetrating-radar (GPR) applications is presented. The estimator is referred to as the TR/GPR range estimator. The motivation for this paper comes from the need of accurately estimating the location of underground objects such as landmines or unexploded ordinance for safe clearance. Second, the Cramér–Rao...

Multimodal detection of subsurface targets such as tunnels, pipes, reinforcement bars, and structures has been investigated using both ground-penetrating radar (GPR) and seismic sensors with signal processing techniques to enhance localization capabilities. Both systems have been tested in bi-static configurations but the GPR has been expanded to a multi-static configuration for improved perfor...

This paper illustrates a prototype system, called GPRS, supporting the Generalized Production Rules (GPR) database language. The GPR language integrates, in a uniied framework, active rules, which allow the speciica-tion of event driven computations on data, and deductive rules, which can be used to derive intensional relations in the style of logic programming. The prototype realizes the opera...

It is well known that a huge number of buried landmines in the post-war countries are still active, and that many civilians are killed or injured by landmine related accidents every year. Therefore, detection and clearance of buried landmines is a very important issue. Metal detectors are the almost universally available fielded devices for landmine detection, but they have great difficulty in ...

In this paper, the predictive value of geopolitical risk (GPR) for return volatility Islamic stocks in Indonesia and Malaysia is examined. GPR data, whether global or country-specific, heighten both countries, albeit with a greater impact on Indonesia. Additional analyses show improved out-of-sample forecast gains inclusion data model stocks.

We develop and test a technique for the creation of coupled surface and subsurface models. Images from a stereo camera are used to estimate the motion of a rover that is collecting ground penetrating radar (GPR) data. The motion estimate and raw sensor data are used to build two novel data products: (1) A threedimensional, photorealistic surface model coupled with a ribbon of GPR data, and (2) ...

This paper illustrates a prototype system, called GPRS, supporting the Generalized Production Rules database language (GPR for short). The language GPR integrates, in a unified framework, active rules, which allow the specification of event driven computations on data, and deductive rules, which can be used to derive intentional relations in the style of logic programming. The prototype realize...

Natural soil pipes are common and significant in upland blanket peat catchments yet there are major problems in finding and defining the subsurface pipe networks. This is particularly important because pipeflow can contribute a large proportion of runoff to the river systems in these upland environments and may significantly influence catchment sediment and solute yields. Traditional methods su...
