Sickle cell anemia patients have 600 times the risk for invasive pneumococcal disease than their healthy peers. High-level cephalosporin resistance was described in the 1990s in healthy children from Tennessee, but its prevalence in sickle cell disease patients is unknown. Pneumococcal isolates from sickle cell disease patients from Tennessee were subjected to multilocus sequence typing to char...

Downhole drilling motors or mud motors are frequently used during the oil and gas well construction, especially for construction of directional and horizontal segments. However, low operation life of the down hole drilling motors and high rate of wear in their working elements may constrain their application due to technical and economical disadvantageousness. In this work, a high-torque modula...

Humans and animals acquire their wide repertoire of motor skills through an incremental learning process, during which progressively more complex skills are acquired and subsequently integrated with prior abilities. Inspired by this general idea, we develop an approach for learning motor skills based on a two-level curriculum. At the high level, the curriculum specifies an order in which differ...

The development and use of a high level synthesis system can be made more convenient when intermediate data can be investigated graphically. Using this graphical representation the designer/user can easily influence the design process or is able to ’tune’ his tools. Mostly a high level synthesis system and a graphical framework are two separate platforms. This article describes how both platfor...

There are many reasons for high level ATPG, but the major one is the need for ATPG to be done at the same level as design. Today a designer has to drop down to gate level to run an ATPG, while verification and most other design activities can be done in RTL. At one time software debugging tools worked at the assembler level, today they work at the level at which people write. Our ATPG tools sho...

In this paper, we study hierarchical supervisory control with partial observations. In particular, we are interested in preservation of supremal normal and supremal controllable and normal sublanguages from the abstracted system (high level) in the original (low level) system. Sufficient conditions are formulated under which the supremal normal or the supremal controllable and normal sublanguag...

This paper describes a vision-based system for autonomous urban transport missions in outdoor environments. Specialized modules are implemented for particular tasks such as lane tracking and navigation along crossing points. A system that can execute a complex mission cannot simply be the sum of its perceptual modalities, and so, there needs to be a "plan" which uses high level knowledge about ...

The high level architecture (HLA) is a standard for federations of distributed simulations that exchange run-time data. HLA’s data distribution management (DDM) services reduce data delivered to simulations based on their declarations of data produced and required. The HLA specifications, including DDM, were changed substantially from the Department of Defense 1.3 standard to the IEEE 1516 stan...

This tutorial surveys the state of the art in high-level synthesis of digital drcuits. It will be published in Advances in Computers, Volume 35, edited by M. Yovits.
