The Role of Gamification in Education - A Literature Review

Abstract: “Gamification” is a concept which aims to increase user experience and engagement with a system, while education is an area with high prospective for application of this concept. A lot of research is ongoing since it seeks to improve the quality of learning of students. Current situation on research of “Gamification in education” is still at initial stages where all of them aim to improve the effectiveness of education activity using game elements. Several ga ps on the studies

Effects of Fibre Volume Fraction on the Compressive and Flexural Experimental Behaviour of SFRC

Abstract: The purpose of this study is to analyse the effects of fibre volume fraction on the mechanical properties of SFRC (Steel Fibre Reinforced Concrete). The results obtained from compression and four-point bending tests carried out on concrete specimens with fibre volume fraction of 1%, 1.6%, 3% and 5% are critically examined. The experimental behaviour in terms of peak load, post-peak behaviour, and residual strength, are evaluated and compared. The fibre distribution and their contribution in Mode I fracture is also assessed. The effects of steel fibre volume fraction on the strength, ultimate strain and ductility index of SFRC are highlighted in order to give a guide for structural use.

Parameters Estimation in Mechanism Design

Abstract: The paper proposes a procedure to estimate the parameters of experimental manipulator robot samples in a series of tests that allows discarding robot samples with parameters being unsuitable for the constructed mechanism. Features of this approach, providing numerical estimates of the parameters are particularly useful in solving the problems of designing space manipulators that require a higher degree of reliability performance. This procedure can also be used in other practice areas, such as analysis of indirect signs of corruption in the socioeconomic, nancial, military, geopolitical and other structures.

Tensile Strength of Steel Fiber Reinforced Concrete

Abstract: Studies have shown that the addition of steel fibers in a concrete matrix improves all the mechanical properties of concrete, especially tensile strength, impact strength, and toughness. The resulting material possesses higher tensile strength, consolidated response and better ductility. Accordingly, this study moves toward deriving an expression that relates split cylinder tensile strength of fiber reinforced concrete to cylindrical compressive concrete strength and fiber reinforcement index, based on data gathered for a wide spectrum of concrete grades, ranging from 20 MPa to 102 MPa. Regression analysis was carried out on gathered data. Eventually a mathematical expression that predicted split cylinder tensile strength of steel fiber reinforced concrete was eventually derived. The predicted values fit well with experimental data.

Constant False Alarm Rate Detection in Pareto Distributed Clutter: Further Results and Optimality Issues

Abstract: The Pareto distribution has been validated recently as a model for X-band high resolution maritime surveillance radar clutter returns. As such, coherent and incoherent detection schemes have begun to appear in the literature. Consequently, constant false alarm rate (CFAR) detectors have also been explored in recent work. This paper introduces some new detectors, designed to manage issues associated with interfering targets and clutter changes in the CFAR training cells. Additionally, the existence of an optimal CFAR is examined, to see whether such a detector can exist as in the Gaussian intensity case.
