The e cient usage of workstations clusters depends rst of all on the distribution of the workload The following paper introduces a method to obtain e cient load balancing for data parallel applications through dynamic data assignment and a simple priority mechanism on a heterogeneous cluster of workstations assuming no prior knowledge about the workload This model improves the performance of lo...

Airborne synthetic aperture radar (SAR) systems are being employed for remote sensing. In some cases the target area is scanned in a square path flight. In order to test data processing algorithms for such datasets, a laboratory experiment has been carried out. Such data acquisition was simulated in a controlled ground based environment with 3 distinct targets. In this paper, two approaches of ...

An algorithm inspired by Genome sequencing is proposed which "reconstructs" a single long trajectory of a dynamical system from many short trajectories. This procedure is useful in situations when many data sets are available but each is insufficiently long to apply a meaningful analysis directly. The algorithm is applied to the Rössler and Lorenz dynamical systems as well as to experimental da...

Within the GIS world, LIDAR becomes an important and convenient data source. Many researchers are developing algorithms to extract a bare-earth model and building boundaries from LIDAR data. This paper presents two different methods for building reconstruction using LIDAR data. The first is a traditional method using filtered LIDAR data and combining cadastral building boundaries data (for exam...

background: the technique most frequently employed for breast reconstruction, either immediate (ibr) or delayed (dbr), is the insertion of a prosthesis. the placement of a foreign body always carries the risk, albeit small, of peri-prosthetic infection and exposure of the implant that necessitates its removal, signaling the temporary or permanent failure of the reconstruction. methods: we retro...

injuries to the posterolateral corner (plc) comprise a significant portion of knee ligament injuries. a high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. in this sense, stress radiographs can help to...

3D reconstructions from photographs often exhibit poor robustness and global consistency. This is a problem in applications such as model acquisition and registration where global consistency is needed to ensure that the reconstruction looks acceptable from all views. Our goal is to develop a robust reconstruction approach which leads to better consistency between viewpoints. We do this by solv...

Automatic speech recognition (ASR) performance degrades rapidly when speech is corrupted with increasing levels of noise. Missing data techniques (MDT) constitute a family of methods that tackle noise robust speech recognition based on the so called missing data assumption proposed in [1]. MDTs assume that (i) the noisy speech signal can be divided in speech-dominated (reliable) and noise-domin...
