in  this  work,  a  new  hybrid  organometallic-inorganic  hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the  surface  of magnetite  nanoparticles. covalent  grafting of silica coated magnetite nanoparticles (scmnps) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (ampscmnps). then, schiff base condensation  of ampscmnps with acet...

The paper proposes a new translation algorithm that translates a hybrid system described as a discrete hybrid automaton (DHA) into an equivalent piecewise affine (PWA) system. The translation algorithm exploits, among others, a new technique for cell enumeration in hyperplane arrangement, all proposed in this paper. The new translation technique enables the transfer of several analysis and synt...

For the purpose of studying stability of hybrid automata, we will again drop reference to inputs (and outputs) of the system and focus on the state trajectory. Later, we will bring the inputs (and outputs) back in when we talk about stabilizing controllers. For reference to the following material, see [1, 2], Chapters 3 and 2 respectively.

Constructed wetlands have not been commonly used in Vietnam due to the lack of information in the selection of proper types of constructed wetlands, type of reeds, design parameters and performance efficiency, in tropical climates. This paper focuses on Canna generalis, which is a common reed and easy to grow both in water and wet land conditions. Two kinds of hybrid constructed wetlan...

We describe a hybrid meta-heuristic algorithm for combinatorial optimization problems with a specific reference to the travelling salesman problem (TSP). The method is a combination of a genetic algorithm (GA) and greedy randomized adaptive search procedure (GRASP). A new adaptive fuzzy a greedy search operator is developed for this hybrid method. Computational experiments using a wide range of...

Timed and weak timed simulation relations are often used to show that operations on hybrid systems result in equivalent behavior or in conservative overapproximations. Given that systems are frequently designed and verified in a modular approach, it is desirable that this relationship is compositional, which is not the case for hybrid systems in general. We identify subclasses of linear hybrid ...

A methodology for synthesizing control laws of hybrid systems is proposed using the hybrid automaton framework. The objective is to synthesize guards for making phase transitions to ensure that the system satisses global invariance over the whole state space. Classical analysis is used to derive a controller given the phases, transitions and global invariance of a hybrid system. The methodology...

We propose an online diagnosis approach for a class of hybrid systems. The normal and the faulty behaviors of the system are modeled with rectangular hybrid automata. Our approach is based on the use of a diagnosis procedure which performs, online, an estimation of the system states, within a given time window, and based on the current record of observable timed events. Each new estimation can ...

in order to evaluate the effect of different planting patterns and different varieties of corn on quantity management in 2015 as a split-plot in a randomized complete block with 3 replications. the test pattern as the main factor in two levels in the atmosphere and the stack corn hybrids in four sub-levels maxima, asv3, magi 704 and 400 were hybrids. the effect of planting pattern, the maximum ...
