AlihabyProblem statement: In this study the equilibrium points and their local stability are found for SIQ and SIQR epidemic models with three forms of the incidence rates. Also, we study the global stability of the equilibrium by constructing the new forms of Liapounov functions. Conclusion/Recommendations: We explored the existence of Hopf bifurcation for some parameters in the given model. …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,274 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordAnalysis and Mechanical Design Solutions for Sit-To-Stand Assisting DevicesPierluigi Rea, Erika OttavianoSit-to-stand can be considered the most common daily-life activity and it can be defined as a change of posture, in which the base of support is transferred from the seat to the feet. It requires both voluntary movement of different body segments that contribute to the equilibrium and control during an important displacement of the Centre Of Gravity of the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 11 Dec 2016 · 7,834 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Empirical Analysis of Supply Response of Rubber in MalaysiaGhulam Mustafa, Ismail Abd Latif, Henry EgwumaSupply response of rubber to changes in economic incentives is analysed using co-integration approach. Time series data is taken for the period 1990 to 2014 and the vector error correction model framework has been applied. The empirical results confirmed the existence of a unique long-run equilibrium relationship among planted acreage, the relative price of rubber and price of fertilizer. Further, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 25 Nov 2016 · 7,493 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDialectic Form Finding of Structurally Integrated Adaptive StructuresL. Rhode-Barbarigos, V. Charpentier, S. Adriaenssens, O. BaverelStructural engineering, prompted by advances in mechanics and computing as well as design principles such as sustainability and resilience, is evolving towards adaptive structures. Adaptive structures are structures that use active components to change shape and properties in response to their environment and/or to their users' desires. Form-found structures, such as tensegrity and shell structures, can be designed to accommodate … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Jul 2015 · 7,850 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMathematical Model to Simulate Tuberculosis Disease Population DynamicsO.K. Koriko, T.T. YusufA mathematical model to depict Tuberculosis disease population dynamics was presented. The model population was compartmentalised as appropriate and the resulting model equations were solved numerically while different instances of the disease transmission were simulated. The graphical profiles of the various sub-populations with time were presented and discussed based on the results from our simulations. Also, the disease-free and endemic … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,623 accessesView PDFCite

Besigye-BafakiThe modes of transmission of schistosomiasis are considered. The transmission model is developed with an aim of establishing possible endemic equilibria within the community. Analysis of the model reveals that if the recovery rate β of human infectives and the death rate of snails δ are increased and if at the same time the contact rate κ of the human … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 6,506 accessesView PDFCite
