Markov chain model for the dynamics of cooking fuel usage: Transition matrix estimation and forecasting

Markov chain models are valuable tools for modeling data that vary over time. They are suitable models to use when modeling the transitions of variables between discrete states over time. In this paper, Markov chain model was applied to the data obtained from 300 households living in the headquarters of three Local Governments (Argungu, Arewa, and Augie) of Kebbi State, Nigeria. The data was information concerning the...

Studies on zinc oxide thin films by chemical spray pyrolysis technique

Zinc oxide (ZnO) thin films were deposited by chemical spray pyrolysis (CSP) technique using zinc acetate dihydrate solutions on microscopic glass substrates by varying the precursor concentration. The prepared films were characterized structurally and optically, using the powder X-ray diffraction (XRD) and UV analysis and Photoluminescence analysis. Crystallographic properties were analyzed through powder XRD. The XRD...

Kinematics of the human hand applied to the design of prosthesis

This work shows the application of a mechanism of four bars synthetized function used in the development of a prosthetic device with an underacted movement, for its application in people with a mutilation level close to the distal dislocation of the wrist. A methodology is exposed for this, from which the procedure for obtaining the trajectory of the four bars mechanism through the function synthesis, which was...
