We consider the heat equation in a bounded domain Ω ⊂ ℝr : $$ \frac{{\partial u}}{{\partial t}}(x,t) = \Delta u(x,t) + \sigma (t)f(x) (x \in \Omega ,0 < t < T)$$ $$ u(x,0) = 0 (x \in \Omega ), \frac{{\partial u}}{{\partial n}}(x,t) = 0 (x \in \partial \Omega ,0 < t < T)$$ Assuming that σ is a known function with σ (0)…

Drying of residual treatment sludge is one of prerequisites in final disposal of this hazardous material. In this study, sludge drying potential (SDP) of different sludge types (DST) and the effect of organic content and commonly used chemical additives, including polyelectrolyte and lime, on SDP were investigated in…

This brief deals with an adaptive barrier-based fault-tolerant control of a probe-and-drogue refueling hose (PDRH) under varying length, actuator fault, and constrained output. First, we consider the actuator working normally, and a model-based control law with barrier function is developed to stabilize the elastic vi…

In this study, we investigated the effect of fire retardants (FRs) on the combustion performance of medium-density fiber boards (MDFs) that were coated with mixtures of water, binder, calcite, and various FRs (FR coatings). We used MDF panels, calcite as the coating pigment, melamine formaldehyde as the binder, and FR…

Zinc borate is a boron-containing chemical material that is used to increase the flame retardancy of polymeric materials, dyes, cables, fabrics, carpets, and the internal parts of automobiles and planes. Commercially used zinc borate, which has the formula of 2ZnO· 3B$_{2}$ O$_{3}$· 7H$_{2}$ O, has a particle size bet…
