Dynamic Matrix Control Versus Nonlinear ModelPredictive Control for the Van de Vusse ContinuousStirred-Tank Reactor: Diagnosing and Correcting aCost-Function Pathology That Masked NMPC’sTrue Performance
Abstract: The Van de Vusse reaction in a continuous stirred-tank reactor (CSTR) is a benchmark for nonlinear multivariable control, but its narrow operating envelope creates a trap for nonlinear model predictive control (NMPC): when the setpoint step is small relative to the plant’s reachable range, a standard quadratic NMPC cost function can make zero control action mathematically optimal, even with a perfect prediction model. This paper documents that failure mode, traces …

Nanoenabled resinbased composites in restorative dentistry: mechanical performance, aesthetic outcomes, and global regulatory considerations
Abstract: Resinbased composites are central to contemporary restorative dentistry but remain constrained by polymerization shrinkage, wear and color instability, which compromise longterm restoration success. Nanoenabled resinbased composites (nanocomposites) have been developed to overcome these limitations by incorporating nanosized fillers and engineered nanostructures into conventional resin matrices, thereby enhancing mechanical properties and optical performance. This narrative Review summarises current evidence on the evolution, composition, and mechanisms of nanoenabled resinbased composites; compares their …

Analyze Effect Of Skew Angle On Performance of R.C Girder Bridge Deck
Abstract: Abstract - The performance of reinforced c oncrete (R.C) girder bridge decks is significantly influenced by geometric configurations, among which the skew angle plays a critical role. Skewed bridges are commonly employed to accommodate site constraints, road alignment, and river crossings, but they introduce complex stress distributions, torsional effects, and differential deflections compared to straight bridges. This study investigates the effect of varying skew angles on the structural behavior of …

A Review: Performance analysis of overlapping shear keys in box girder bridges using finite element based software
Abstract: Abstract - Box girder bridges are widely used for long-span constructions due to their high strength-to-weight ratio and structural efficiency. A fundamental component in these bridges is the shear key which allows for effective transfer of loads between bridge segments and upholds the overall structural performance through the different load cases. Overlapping shear keys are becoming increasingly popular because they greatly enhance inter-segment connections, which decrease relative displacements. This paper …
