Reduction has been linked visually in art since man began making functional and aesthetic forms, and this beginning can be identified with cave paintings. Reduction is one of the clearest indications of intellectual presence in aesthetic experience. Modernism was greatly supported by the great transformations that the intellectual movement witnessed in the world in general and in Europe in particular. There, and their transfer of European artistic experiences, and the reflection of this influence in their aesthetic sculptures, and for this reason the researchers find that the study of the aesthetic references of the reductive forms in the Iraqi sculptural experience represents a great importance in the study of the history of contemporary sculpture, to consider the concept of reduction and its performance applications, so the research includes four chapters The first chapter included the methodological framework for the research, and in it we reviewed the research problem, as we explained in it the plastic art’s dealings in general with the concept of reduction, and then the applications of reduction in the art of European and Iraqi sculpture, starting from this question: What are the references for selection in contemporary Iraqi sculpture? Then we presented the importance of the research and its aim in identifying the working mechanisms of the concept of shorthand and its references in contemporary Iraqi sculpture, and the limits of research between (2003-2023), and we showed a number of definitions of shorthand linguistically, idiomatically and procedurally.Then, in the second chapter marked by the theoretical framework of the research: we presented three topics, the first of which was devoted to the concept of shorthand and its performance applications in the arts of ancient civilizations. The second topic was devoted to the study of reductionism in the arts of European modernity, and in the third topic, we dealt with reductionism in contemporary Iraqi sculpture, and then presented the theoretical framework indicators.In the third chapter tagged: the procedural framework of the research: we presented the research community, which included all the Iraqi artists who worked in the shorthand format in their sculptural works within the limits of the research, and we set a number of conditions for choosing the research sample, and it was chosen in an intentional way, and it included four samples, and we also used the observation tool to collect The research sample information, and the analysis was done according to the descriptive analytical method.The researchers reached a number of results, including: that the act of reduction is a dominant and distinctive feature in the outputs of contemporary Iraqi sculpture, which depends on simplification, pruning and deletion, and also achieved by symbolic abbreviations in the artwork and the concentration and intensification of the significance, as it appeared that the contemporary Iraqi sculptor was influenced by the European artistic schools and trends that dominated On the global artistic act in the twentieth century, and what followed within the precursors of preoccupation with the arts of modernity and beyond, in addition to being affected by the cultural depth of the civilization of the Mesopotamia Valley, just as reductionism achieved for the sculptor proof of his self and personal style, then we presented recommendations and proposals. Then we included proven sources, references and appendices.
In this paper, wavelets were used to study the multivariate fractional Brownian motion through the deviations of the random process to find an efficient estimation of Hurst exponent. The results of simulations experiments were shown that the performance of the proposed estimator was efficient. The estimation process was made by taking advantage of the detail coefficients stationarity from the wavelet transform, as the variance of this coefficient showed the power-low behavior. We use two wavelet filters (Haar and db5) to manage minimizing the mean square error of the model.
A novel demountable shear connector is proposed to link a concrete slab to steel sections in a way that resulting steel-concrete composite floor is demountable, i.e. it can be easily dismantled at the end of its service life. The proposed connectors consist of two parts: the first part is a hollow steel tube with internal threads at its lower end. The second part is a compatible partially threaded bolted stud. After linking the stud to the steel section, the hollow steel tube can be fastened over the threaded stud, which create a complete demountable shear connector. The connector is suitable for use in both composite bridges and buildings, and using cast in-situ slabs, precast solid slabs, or hollow-core precast slabs. A series of push-off
... Show MoreDue to its importance in physics and applied mathematics, the non-linear Sturm-Liouville problems
witnessed massive attention since 1960. A powerful Mathematical technique called the Newton-Kantorovich
method is applied in this work to one of the non-linear Sturm-Liouville problems. To the best of the authors’
knowledge, this technique of Newton-Kantorovich has never been applied before to solve the non-linear
Sturm-Liouville problems under consideration. Accordingly, the purpose of this work is to show that this
important specific kind of non-linear Sturm-Liouville differential equations problems can be solved by
applying the well-known Newton-Kantorovich method. Also, to show the efficiency of appl
In this paper , an efficient new procedure is proposed to modify third –order iterative method obtained by Rostom and Fuad [Saeed. R. K. and Khthr. F.W. New third –order iterative method for solving nonlinear equations. J. Appl. Sci .7(2011): 916-921] , using three steps based on Newton equation , finite difference method and linear interpolation. Analysis of convergence is given to show the efficiency and the performance of the new method for solving nonlinear equations. The efficiency of the new method is demonstrated by numerical examples.
Geologic modeling is the art of constructing a structural and stratigraphic model of a reservoir from analyses and interpretations of seismic data, log data, core data, etc. [1].
A static reservoir model typically involves four main stages, these stages are Structural modeling, Stratigraphic modeling, Lithological modeling and Petrophysical modeling [2].
Ismail field is exploration structure, located in the north Iraq, about 55 km north-west of Kirkuk city, to the north-west of the Bai Hassan field, the distance between the Bai Hassan field and Ismael field is about one kilometer [3].

... Show MoreThe flexible joint robot manipulators provide various benefits, but also present many control challenges such as nonlinearities, strong coupling, vibration, etc. This paper proposes optimal second order integral sliding mode control (OSOISMC) for a single link flexible joint manipulator to achieve robust and smooth performance. Firstly, the integral sliding mode control is designed, which consists of a linear quadratic regulator (LQR) as a nominal control, and switching control. This control guarantees the system robustness for the entire process. Then, a nonsingularterminal sliding surface is added to give a second order integral sliding mode control (SOISMC), which reduces chartering effect and gives the finite time convergence as well. S
