**Speech Title:** Optimal Control Computation for
Nonlinear Switched Systems

**Abstract: **Switched systems operate by switching among various
modes or subsystems. This talk considers optimal control problems
governed by nonlinear switched systems in which the mode dynamics are
described by nonlinear differential equations. A computational method
for computing the optimal control for this optimal control problem is
presented. This computational method is based on some key ideas in
optimal control computation, which include control parameterization,
time-scaling transformation, and the constraint transcription method.
Two real-world practical examples are discussed.

**Speech Title:**Developing interval type-2 fuzzy
moving average control charts

**Abstract:** Previous literature suggests that fuzzy control charts
are more sensitive than conventional one hence, it provides better
quality and conformance of products. However, it is known that much of
the data used in the manufacturing sector cannot be expressed by type-1
fuzzy numbers and some of it is more suitable to be expressed in type-2
fuzzy numbers. This paper aims to develop interval type-2 fuzzy moving
average (IT2F-MA) control charts by incorporating interval type 2
trapezoidal fuzzy numbers as input data for the case of known and
unknown standard deviations. To verify the performance of the proposed
control chart, normal distribution based-average run length (ARL) was
computed and compared to type-1 fuzzy MA charts and conventional MA
charts. Twenty samples with a sample size of six of fertilisers’
production were examined to identify the defects. Based on the
conventional MA chart, 8 out of 20 samples were “out of control”. On the
other hand, the type-1 fuzzy MA chart found 10 defects, whereas the
interval type-2 fuzzy MA chart found 15 samples to be defectives. Thus,
we can conclude that interval type-2 fuzzy chart is more sensitive and
takes a lesser number of observations to identify the shift in the
process. In addition, the ARL test showed that interval type-2 fuzzy MA
outperformed the other control charts under the comparison of ARL. The
ability is attributed to the introduction of interval type-2 fuzzy
numbers to the MA and the explicit formula of ARL where the quality of
fertilisers production can be improved.

**Speech Title:** A New Challenge in the Field of
Mathematics

**Abstract: **The main purpose of the report is to suggest an entire
function associated with the completed Riemann zeta function. The entire
function on the critical line is expressed by the Fourier cosine
integral. Compared with the Riemann hypothesis, it is showed that a
hypothesis is that its zeros have the real part equal to 0.5. This is a
new challenge in the field of mathematics showed in the Fractals
Challenge of the journal Fractals.

**Abstract: **New governing equation for the
transverse vibration of fully coupled thermo-magneto-electro-elastic
(TMEE) thin laminates accounting for entropy constitutive equation is
derived in this paper. In particular, free vibration for the bi-layered
BaTiO3-CoFe2O4 composite and the three-layered laminate made of CoFe2O4
/ BaTiO3 stacked on elastic Epoxy are implemented as demonstration
examples. Complete constitutive equations regarding the elastic
stresses, electric displacements, magnetic fluxes as well as the entropy
of the thermodynamic system are revisited, their corresponding
alternative forms are further introduced so that Navier elastic
equation, the Gauss’ laws in the absence of free charges and currents,
and the steady-state heat equation can be applied. Based on the
Kirchhoff thin plate theory in accordance with the non-zero out-of-plane
field assumptions, bending problem for the transversely isotropic TMEE
rectangular plates is investigated, governing equation in terms of the
transverse displacement is then presented in a rather compact form. The
effective material coefficients for the TMEE laminate are presented and
expressed via the volume fraction (vf) of either the piezoelectric phase
constituent or the piezomagnetic phase constituent. Natural frequencies
of the proposed TMEE coupling thin plates are analytically evaluated,
and the effects of different volume fraction on the natural frequency
are discussed; in addition, the existence of elastic substrate Epoxy and
its effect are further investigated.
