We examined the environmental dissemination of Acinetobacter nosocomialis multilocus sequence typing clonal complex 260/71 in Rio de Janeiro, Brazil, including water from a dam and food samples. The increasing use of sequence based methods has demonstrated a large, previously unpredicted, dissemination of bacteria that may serve as opportunistic pathogens.

We study collisional loss rates due to spin-exchange collisions in very-low-intensity Rb magneto-optical traps. The loss rate exhibits an unpredicted intensity dependence for low intensities, accounting for a large disparity between loss rates observed in light-force traps and magnetically confined Bose condensates. Possible collision mechanisms considered include light-altered collision phase ...

Combustion supervision by evaluating flywheel speed variations is a common approach in the automotive industry. This often involves preliminary measurements. An adequate model for simulating flywheel speed can assist to avoid some of these preliminary measurements. A physical nonlinear model for simulating flywheel speed based on cylinder pressure information is investigated in this work. Measu...

Neutralization of external stimuli in dynamic systems has the major role in health, life, and function of the system. Today, dynamic systems are exposed to unpredicted factors. If the factors are not considered, it will lead to irreparable damages in energy consumption and manufacturing systems. Continuous systems such as beams, plates, shells, and panels that have many applications in differen...

Path-oriented scheduling methods, such as trace scheduling and hyperblock scheduling, use speculation to extract instruction-level parallelism from control-intensive programs. These methods predict important execution paths in the current scheduling scope using execution pro ling or frequency estimation. Aggressive speculation is then applied to the important execution paths, possibly at the co...

Feature matching is one of the basic approaches to many of computer vision applications, such as object recognition. Dealing with illumination variations is an open problem in this field. In this paper we present an approach to make a more robust algorithm against real world illumination changes and variations in direction of the light source on our object of interest, by using a set of trainin...

This paper presents a first analysis of MERIS-Full Resolution (FR) data to observe seasonal variations of the reflectances of agricultural fields in two regions with different climatic conditions: Toulouse (France) and Barrax (Castilla-La Mancha, Spain). The objective is to assess the capabilities of MERIS for crop monitoring. After applying an atmospheric correction method to the images we hav...

The Time-Interleaved Analog-to-Digital Converter (TI-ADC) is an efficient approach to systems requiring very high sampling rate with medium to high resolution. However, interchannel mismatches and process variations appear as a main bottleneck leading to substantial degradation in global TI-ADC performance. In this paper, an adaptive compensation technique is proposed for improving the overall ...
