Context. Flares, eruptive prominences and coronal mass ejections are phenomena where magnetic reconnection plays an important role. However, the location and the rate of the reconnection, as well as the mechanisms of particle interaction with ambient and chromospheric plasma are still unclear. Aims. In order to contribute to the comprehension of the above mentioned processes we studied the evol...

As life expectancy in the industrialized world increases, so does the number of elders with chronic health conditions such as diabetes and congestive heart failure that require complex self-management routines. The traditional model of episodic care in clinic and hospital-based settings is not optimal for improving chronic disease outcomes. Instead, solving these issues requires a low-cost long...

This technical report presents the recent progress in the design and construction of a closed loop automated seating system. Preliminary test results are reported. The system is designed to measure seating surface forces and control the seating surface geometry of a seated human. It uses force information as feedback to determine custom seating contours which produce desired seating characteris...

statement of problem: t-loop is one of the most popular closing loops in orthodontic profession. however its activation is in the contrary to bouschinger effect theory, since the formed bends would be opened during activation. the purpose of this study was to add a helix in a way to be more respondent to the bouschinger effect theory. objectives: to compare the load deflection, maximal elastic ...

a mobile manipulator robot is known as a complex system due to some properties such as coupling between the manipulator and mobile chassis, holonomic and nonholonomic constraints, multivariable and nonlinear dynamics. the control of robot faces the external disturbance, parametric uncertainty and unmodeled dynamics. therefore, the use of an adaptive fuzzy system is suggested for its capability ...

Linking feedback loops and system behavior is part of the foundation of system dynamics, yet the lack of formal tools has so far prevented a systematic application of the concept, except for very simple systems. Having such tools at their disposal would be a great help to analysts in understanding large, complicated simulation models. The paper applies tools from discrete mathematics and graph ...

This paper presents new results for formal validation of system-level loop transformations in the context of power eecient caching. Our main target domain consists of data-dominated applications in the multi-media area, dealing with complex loop nests containing composite data types like (multi-dimensional) arrays and lists. Global transformations applied on such loop nests cannot be formally v...

This paper continues the discussion of the detailed experimental study conducted on adaptive optical control methodologies inside a laser resonator.(1) In this paper we discuss the experimental results for the correction of tilt within a laser resonator utilizing a multidither zonal COAT system. The tilt aberration was introduced in three different ways: (1) static tilt was introduced while the...
