Optimal homotopy asymptotic approach to nonlinear oscillators with discontinuities

In this paper a version of the optimal homotopy asymptotic method (OHAM) has been proposed and applied to nonlinear oscillators with discontinuities. The main objective was to obtain highly accurate analytical solutions for a particularantisymmetric constant force oscillator using this new procedure. The proposed procedure proved to be very effective and accurate and did not require linearization or small...

Amelioration of aluminium induced toxicity by Allium sativum

Garlic (Allium sativum L., Liliaceae) is a nature’s boon to mankind, which has played an important dietary and therapeutic medicinal role throughout the history of mankind. Aluminum (Al) is a potent neurotoxin and has been associated with Alzheimer's disease causality for decades. The study aims to demonstrate the ameliorative effect of garlic extract against aluminium-induced toxicity in rat model....

Temperature compensation of hot wire mass air flow sensor by using fuzzy temperature compensation scheme

Mass air flow sensors are increasingly used in the automotive industry to measure the mass air flow intake into the internal combustion engine. A problem occurred with the basic circuit for bridge type mass air flow sensor is the measurement accuracy of the sensor is affected by the temperature variation in the air. This paper presents the development of an open loop Fuzzy Temperature Compensation Scheme (FTCS) for hot...

Response of selected wheat genotypes to ethylmethanesulphonate concentration, treatment temperature and duration

Ethylmethanesulphonate (EMS) is the most useful chemical mutagen to induce genetic variation in plant breeding programs. Key factors in inducing mutations with EMS include dose, genotype, temperature and duration of treatment. This study was conducted to determine the optimum EMS concentration, treatment temperature and duration for effective mutagenesis in selected wheat varieties. Seeds of four varieties (B936, B966,...

A novel extrapolation method for value prediction applications

This paper presents a simple extrapolation method for value prediction applications. Classical statistical analysis methods are not used for the proposed method instead some basic mathematical and constitutional properties of the system responses are used, and relationships between the samples are modeled. Detailed mathematical description of the proposed method is given and obtained results are justified using...
