Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,935 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharcoal-Oil Mixture as an Alternative Fuel: A Preliminary StudyRoila Awang, Choo Yuen MayThe fast depletion of fuel oil and continuous increase in the demand for power is a global issue. The world energy consumption is projected to grow at an average of 2.7-3.7% from 1996 to 2010. Therefore search for alternative fuel is highly prioritized. Thus this study presents the results on the characteristic of charcoal-oil mixture as an alternative fuel. The … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,556 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordYear-Round Forage Yield Stability through a System Combining Triple-Maize Crops with Winter Barley in Kyushu, JapanYingkui Yang, Yasuyuki Ishii, Sachiko IdotaReduction of feeding cost for the beef and dairy cow industry is an urgent matter requiring the intensification of summer and winter forage cropping in Kyushu, Japan. Forage maize is a prominent high-yield summer crop in the region, where it used to be sown from late March to early August. Due to global warming, maize cropping in the common hot … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 1 · 21 Jan 2016 · 7,296 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of the Stability of Underground Rock Pillars through a Probabilistic ApproachMassimo Guarascio, Pierpaolo OresteProblem statement: When the room and pillar mining method is adopted, the dimensioning of the rock pillars is one of the most important aspects that need to be faced from the engineering point of view. The available calculation methods are usually simplified and involve the areas of influence method for the evaluation of the mean axial stress induced in the … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 30 Jun 2012 · 7,031 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMass Structure Deformation Monitoring using Low Cost Differential Global Positioning System DeviceRamin S. Azar, Helmi Z.M. ShafriIn this study, a technique for monitoring bridge deformation with the simplest GPS device available was demonstrated. The accuracy of these observations was evaluated and the best approach for this purpose was suggested. The device used was the low cost GS20 Leica single frequency GPS, which is a basic GPS receiver for this study. This study was done during March, … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 8,799 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordGlobal Behavior of a Higher Order Difference EquationAlaa E. Hamza, R. Khalaf-AllahIn this work we study the asymptotic stability of the nonnegative equilibrium points of the difference equation. We discuss the conditions under which there exist prime period two solutions and semicycles. Finally we investigate the oscillation and the existence of unbounded solutions. …Journal of Mathematics and Statistics, Vol. 3, Issue 1 · 31 Mar 2007 · 7,054 accessesView PDF Cite
