This paper presents a study on self-tuning control strategies with generalized minimum variance control in a fixed two degree of freedom structure–or simply GMV2DOF–within two adaptive perspectives. One, from the process model point of view, using a recursive least squares estimator algorithm for direct self-tuning design, and another, using a Mamdani fuzzy GMV2DOF parameters scheduling technique based on analytical and physical interpretations from robustness analysis of the system. Both strategies are assessed by simulation and real plants experimentation environments composed of a damped pendulum and an under development wind tunnel from the Department of Automation and Systems of the Federal University of Santa Catarina.

Abstract. The maritime industry is huge and consists of a lot of complex processes. It is a consequence of the fact that the maritime industry provides most of the goods transportation. During transportation, people serve the vessel. And here the problem is raised of the optimal distribution of crew on vessels. This problem can be solved by formalizing the integer programming problem. In practice, we saw that solving this problem is time-consuming since there are a large number of free variables. This makes the solution inapplicable to the end-user. In this work, we describe the approach to speed up a solution of crew optimization for the maritime industry using the Rolling Time Horizon technique. Our approach is 3.5 times faster than the benchmark and deviates from the optimal solution by less than 1%.
Nonlinear Aeroelastic Steady Simulation Applied to Highly Flexible Blades for...Fausto Gill Di Vincenzo
A novel approach is presented to perform nonlinear aeroelastic steady-state simulations of highly flexible structures such as fix wings and rotating blades. The methodology has been developed in a specific OpenFSI service available in MSC Nastran SOL 400 that
includes follower forces and incremental loads features to allow for accurate nonlinear steady Fluid-Structure Interaction analysis. The new service, called HSA.OpenFSI, based on the HSA Toolkit, has been implemented to couple MSC Nastran to a CFD solver. Six DOF spline technology is used to interpolate data between the aerodynamic and structural grids. A new approach has been designed to improve the efficiency of this technology that allows to considerably reduce the time needed to create the interpolation spline matrix and the disk space to store it. A Nastran-based FEM algorithm has been developed to take care of the fluid domain deformation. The proposed approach has been validated on a flap in a duct model, where transient steady-state results are available from other approaches, and then preliminary results on a proprotor two-blade model of Micro Air Vehicles MAV from ISAE will be presented.
Computational fluid dynamics (CFD) is a powerful tool to simulate, analyze, and optimize designs. The leading CFD providers will discuss software features and functionality such as flow features and benefits, solver technology, as well as describe an example of CFD use in the real world.

Computational fluid dynamics (CFD) is frequently used in the initial design stages of industrial pump design, analyzing the overall performance as well as more specific aspects, ultimately as a tool to determine ways in which it can be improved.
Drag Reduction of Front Wing of an F1 Car using Adjoint Optimisationyasirmaliq
The Project Poster summarizes the aims and objectives of the Final Year Dissertation. The project starts with a detailed study on the parameters that tend to affect the performance of front wings of an F1 car and goes through designing the front wings(3) with endplates and wheel, meshing it, solving/analysing the flow and finally optimising the selected geometry using Fluent Adjoint Solver for efficient performance.
Adjoint optimisation technique is used to achieve optimal performance from the front wings. It's the most successful shape optimisation method as it's independent of the number of design variables exponentially reducing computational time and cost. The emphasis has been put on optimising the shape of the front wings using the Adjoint method as it’s the most efficient and computationally inexpensive method for design optimisation. The approach towards shape optimisation is downforce constrained drag minimization as it would result in keeping a constraint on downforce and reducing the drag at the same time, thus producing optima for a given downforce/drag value.
Flow Modification over Rotor Blade with Suction Boundary Layer Control TechniqueIJERA Editor
The efficiency of transonic aircraft engines depend upon the performance of compressor rotor. To increase
compressor rotors performance flow separation around rotor blades must be delayed and controlled. The aim
was to control the flow separation of blades using suction boundary layer control method.
Rotor blade has been modelled in designing software CATIA and then a suction surface has been created on
blade and then import these geometries to ANSYS-CFX 14.5 for computational analysis of flow around blades.
Suction slot has been applied at the trailing edge of suction surface and Shear stress transport model has been
used for computational analysis.
Two different suction mass flow rates 1 kg/s and 1.5 kg/s have been used here and boundary layer separation
effects have been changed and this could be readily seen that the velocity vectors have reattached, preventing
the boundary layer separation at the suction surface of the blade.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
