The quality of manufactured products is characterized by many controllable quality factors. These factors should be optimized to reach high quality products. In this paper we try to find the controllable factors levels with minimum deviation from the target and with a least variation. To solve the problem a simple aggregation function is used to aggregate the multiple responses functions then a...

We prove a continuity inheritance property for super- and sub-additive transformations of non-negative continuous multivariate functions defined on the domain of all non-negative points and vanishing at the origin. As a corollary of this result we obtain that super- and sub-additive transformations of continuous aggregation functions are again continuous aggregation functions.

We consider reasoning and minimization in systems of polynomial ordinary differential equations (odes). The ring of multivariate polynomials is employed as a syntax for denoting system behaviours. We endow polynomials with a transition system structure based on the concept of Lie derivative, thus inducing a notion ofL-bisimulation. Two states (variables) are provenL-bisimilar if and only if the...

We develop a technique to evaluate the faulttolerance of a multi-agent system whose number of agents is unknown at design time. We present a method for injecting a variety of non-ideal behaviours, or faults, studied in the safety-analysis literature into the abstract agent templates that are used to generate an unbounded family of multiagent systems with different sizes. We define the parameter...

Objective(s):Alzheimer's disease (AD) is the most common age-related neurodegenerative disorder. One of the hallmarks of AD is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. In this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in AD and tauopathies. Unfortunately, the available syntheti...

How mixed-species groups perform collective behaviours provides unique insights into the mechanisms that drive social interactions. Herein, we followed the aggregation process of two isopod species under monospecific and heterospecific conditions at three population densities. Our experimental results show that the formation of both the monospecific and heterospecific groups responds to a simil...

There is growing interest in understanding the ecological benefits of oil and gas structures. This first reported case spawning aggregation mating behaviour bigeye trevally, Caranx sexfasciatus, associated with an platform, demonstrating that jackets are capable not only attracting large aggregations fish, but can provide suitable conditions for reproductive purposes. Fish (FSAs) highly vulnera...

Aggregation is generally a time consuming process that is only marginally suited for interactive result exploration. This work presents a framework of techniques to support an extended aggregation that works online and is controllable by user feedback. Supportive visualisation methods are presented as well as an overview of applicable interaction techniques and a generic architecture combining ...

When tobacco is smoked, chewed or snuffed, nicotine is absorbed by the lungs or mucous membrane and quickly moved into the bloodstream, where it is circulated throughout the brain. In fact nicotine is highly dangerous to be consumed in any form. The present study was conducted to know the adverse effects of nicotine on the platelet aggregation in cerebral microvessels of mice. Male mice of aver...

Introduction: Methadone has been used as a drug to detoxify opioid tolerance. Naloxane precipitated morphine withdrawal behaviours were attenuated by venlafaxine as an antidepressant. On the contrary, after detoxifying the opioids, spontaneous withdrawal syndrome may occur with pain sensitivity. Therefore the present study aimed to examine the effects of chronic methadone (70 mg/kg, in dr...
