The Influence of Intellectual Intelligence and Learning Motivation Against Student’s Mathematics Learning Outcomes In Region 3 Kelurahan Pegadungan Jakarta Barat

This study aims to prove the influence of intellectual intelligence and learning motivation on students' math learning results partially or simultaneously. Defenisi learning results in this study is the acquisition of the student's learning process in accordance with the objectives of teaching in the cognitive sphere covering aspects of C1 (remember), C2 (understand), and C3 (applying). Intellectual intelligence or IQ is often referred to as intelligence that refers to a person's cognitive abilities, namely high thinking ability in an effort to improve a student's abilities, the ability to reason to plan problems, understand ideas, use language and learn. Learning motivation is a mental drive or strength that encourages, moves, and directs students to learn. This research uses quantitative approach with survey method. The sampling technique uses propotional random sampling techniques. The sample of this study was grade 6 students with a total of 92 students. Instruments used in the form of IQ test data, questionnaires and tests. Data analysis using multiple linear regression regression. The results showed that (1) Intellectual intelligence has a significant influence on students' math learning outcomes, (2) learning motivation has a significant influence on students' math learning outcomes, (3) Intellectual intelligence and learning motivation have a significant influence on students' math learning outcomes. The results of this study can be used as a reference for schools that want to get maximum student math learning results.

Study of the formation and development of European sociality

The article considers two main subjects: the author’s perception of sociality and the results of his research of formation and three main stages (Antiquity, Middle Ages, Modern Age) of development of the European sociality. The understanding of sociality is set by means of the characteristic of the sociological approach where four main specific features are distinguished. The first one is an axiological representation of sociality (fairly/unfairly, compliance/non-compliance with an ideal reference) and focus on alteration or improvement of sociality. The second one is the analysis of mass behaviour and social order. The third one is studying of sociality, since ancient culture; nature of sociality and revealing its laws. A dilemma is formulated: what studies or, more precisely, has to study the sociology – modernity or postmodernity? The fourth one is that sociology considers sociality as a modernity phenomenon, i.e. studies mass behaviour of people as such, beyond historical and cultural context. Stating the results of studying of formation and development of the first stages of the European sociality, the author distinguishes protosociality by which he means the previous state and prerequisites of sociality where there were no specific forms of its understanding yet and sociality as such. The author considers characteristics of three main types of sociality: antique one, presuming decision-making by free citizens within a city-state; imperial one, subordinating polis sociality to the centralized emperor management, and medieval one, fancifully combining these two types of sociality. The article raises the issue of the interrelation of social studying and social action. Today, it is not a matter of social laws, but of nonlinear processes which are described with the use of a system approach and synergetic. A social engineer relies in this case on knowledge gained during studying sociality, on the reconstruction of the specific history of sociality, modern social trends. The author sets a task to characterize the relations between such aspects of sociality as economy, state, society, power, masses, culture. He demonstrates that sociality may be presented as consisting of three spheres. In the first one, three main subsystems are distinguished: state, society, and economy, the constituting element being the state. In the second sphere (anthropological one) the author identifies a new European personality, communities, masses, as well as society, but in this case, understood in the anthropological plan. Persons and communities in the anthropological sphere function as a rule in two modes – standard and parasitic ones (rent income, misuse of social structures, etc.). In the third sphere covering two others, sociality is considered in a population context. The point is that the state and the society are not unique, there are a lot of them, and they engage in the various relationship (fight for the territory and resources, competition, assistance to each other, various exchanges, etc.). The author identifies and characterizes the main processes of sociality: globalization and modernization, implementation of social schemes and concepts, “post” and “counter” processes, processes of setting and resolving problems (“challenges” and “responses” thereto). In the last part of the work, the author suggests his reconstruction of the specific history of sociality, as well as social trends of our age.

A Parallel Interval Arithmetic-based Reliable Computing Method on a GPU

Video cards have now outgrown their purpose of being only a simple tool for graphic display. With their high speed video memories, lots of maths units and parallelism, they can be very powerful accessories for general purpose computing tasks. Our selected platform for testing is the CUDA (Compute Unified Device Architecture), which offers us direct access to the virtual instruction set of the video card, and we are able to run our computations on dedicated computing kernels. The CUDA development kit comes with a useful toolbox and a wide range of GPU-based function libraries. In this parallel environment, we implemented a reliable method based on the Branch-and-Bound algorithm. This algorithm will give us the opportunity to use node level (also called low-level or type 1) parallelization, since we do not modify the searching trajectories; nor do we modify the dimensions of the Branch-and-Bound tree [5]. For testing, we chose the circle covering problem. We then scaled the problem up to three dimensions, and ran tests with sphere covering problems as well.

Mathematical and Numerical Modeling of Turbulent Flows

The present work is devoted to the development and implementation of a computational framework to perform numerical simulations of low Mach number turbulent flows over complex geometries. The algorithm under consideration is based on a classical predictor-corrector time integration scheme that employs a projection method for the momentum equations. The domain decomposition strategy is adopted for distributed computing, displaying very satisfactory levels of speed-up and efficiency. The Immersed Boundary Methodology is used to characterize the presence of a complex geometry. Such method demands two separate grids: An Eulerian, where the transport equations are solved with a Finite Volume, second order discretization and a Lagrangian domain, represented by a non-structured shell grid representing the immersed geometry. The in-house code developed was fully verified by the Method of Manufactured Solu- tions, in both Eulerian and Lagrangian domains. The capabilities of the resulting computational framework are illustrated on four distinct cases: a turbulent jet, the Poiseuille flow, as a matter of validation of the implemented Immersed Boundary methodology, the flow over a sphere covering a wide range of Reynolds numbers, and finally, with the intention of demonstrating the applicability of Large Eddy Simulations - LES - in an industrial problem, the turbulent flow inside an industrial fan.

Full Scale Calibration of a Combined Tactile Contour and Roughness Measurement Device

In current production metrology contour and roughness of work pieces has to be controlled in demanding small tolerances. It is important that the results not only have to be accurate, but also the measurement has to be performed effective and fast. It would be convenient to have the possibility measuring first a continuous surface profile and than performing different evaluations on adjacent segments. We describe a measurement system which is based on a tactile probe with a diamond tip. The position of each axis is measured by high resolution and high accuracy digital scales. The instrument is calibrated and traced back by only using one precision sphere covering approximately the whole measuring range of 24 mm. It is shown that with only that macroscopic calibration and adjustment the accuracy for roughness measurement in all arbitrary vertical positions is reached in the nm-range. The calibration and adjustment process is described and we show the verification of the accuracy by measuring several surface specimens. The results are compared to a Physikalisch-Technische Bundesanstalt (PTB) calibration certificates for those surface roughness standards.
