A mathematical model which includes important components such as undiagnosed infectious, diagnosed infectious, latently infected and lost-sight infectious is formulated. The model combines a frequency dependent and a density dependent force of infection for TB transmission. Through optimal control theory and numerical simulations, a cost-effective balance of two different intervention methods is obtained. Seeking to minimize the amount of money the government spends when tuberculosis remain endemic in the Cameroonian population, Pontryagin's maximum principle is used to characterize the optimal control. The optimality system is derived and solved numerically using the forward-backward sweep method (FBSM). Results provide a framework for designing cost-effective strategies for diseases with multiple intervention methods. It comes out that combining chemoprophylaxis and education, the burden of TB can be reduced by 80 \% in 10 years.}, language = {en} } @inproceedings{TaylorKratzensteinKornaropoulosetal.2009, author = {Taylor, William R. and Kratzenstein, Stefan and Kornaropoulos, Evgenios I. and Ehrig, Rainald and Moewis, Philippe and Heller, Markus O.}, title = {Non-invasive Assessment of Skeletal Kinematics}, series = {Measurement and Sensing in Medicine and Health}, booktitle = {Measurement and Sensing in Medicine and Health}, address = {London}, year = {2009}, language = {en} } @inproceedings{TaylorKornaropoulosKratzensteinetal.2011, author = {Taylor, William R. and Kornaropoulos, Evgenios I. and Kratzenstein, Stefan and Ehrig, Rainald and Plank, F. and Heller, Markus O.}, title = {Targeted Marker Placement for the Functional Identification of the Hip Joint Centre}, series = {Transactions Vol. 36, 2011 Annual Meeting of the Orthopedic Society}, booktitle = {Transactions Vol. 36, 2011 Annual Meeting of the Orthopedic Society}, address = {Long Beach}, year = {2011}, language = {en} } @inproceedings{TaylorKoenigSpeirsetal.2006, author = {Taylor, William R. and K{\"o}nig, Christian and Speirs, A. and Ehrig, Rainald and Duda, G. and Heller, Markus O.}, title = {The medio-lateral force distribution in the sheep knee during walking}, series = {5.
