The Impact

The present research aims to analyze and evaluate a didactic and technological tool and see the impact to encourage study in the students of the Systems Engineering School at the National University of Trujillo, during the 2020-II semester. It was possible to implement the Stormboard application for the development of Brainstorming as a didactic strategy through which it is intended to encourage the creative and innovative aspect of students when addressing topics and case studies. Analyzing the results obtained, we can point out that impacts were determined on the level of motivation for the study of students with a value of 8%, as well as the impact on the level of perception of educational services of students was determined in the order of 24% and finally, results of the impact on the level of student satisfaction were obtained in the order of 17%. Finally, it is proposed that these didactic initiatives be taken into account in the academic and institutional policies of the Systems Engineering School of in order to extrapolate the practice to other academic units at the National University of Trujillo.

Value Model

In recent years, a formal, mathematically rigorous, value-based approach to system design has been proposed within the systems engineering community. This approach stands in contrast to the traditional requirements based approach to system design because of its foundations in decision theory. One of the crucial first steps in the value-based approach is the elicitation of information about all the elements that influence a design or acquisition decisions, namely, all actors, system properties and behavior, preferences, and concerns. This elicitation step requires a formalized, model-based method for capturing these elements of the value network, the basis of the decision maker’s value function. In this paper, we examine previous work in the area of elicitation in system design and define a set of elements necessary to effectively elicit a meaningful value network. We then consider a domain-specific profile as an extension of SysML to formally capture the essential elements of a value network. To illustrate the modeling approach, the profile is applied to a case study of the design of a heads-up display system (iHUD) in order to test the depth of the profile as well as to show the value of the model-based approach in the elicitation process.

Value Model

In order to satisfy the application of space science, space-based remote sensing and environmental monitoring in our country, a value model is proposed for distributed reconfigurable satellite system life cycle value assessment in this paper. Besides, many uncertain factors of multi-aspects are considered in this model. The value model is transferred into value assessment tool by means of programming. In addition, the distributed reconfigurable satellite system developed by this tool and the corresponding value assessment system can be applied to space-based application system which is the current technology of the distributed reconfigure satellite system.

Abstract Gilead et al. offer a thoughtful and much-needed treatment of abstraction. However, it fails to build on an extensive literature on abstraction, representational diversity, neurocognition, and psychopathology that provides important constraints and alternative evidence-based conceptions. We draw on conceptions in software engineering, socio-technical systems engineering, and a neurocognitive theory with abstract representations of gist at its core, fuzzy-trace theory.

Natural Brucite (Mg(OH)2) decomposes on heating to form magnesium oxide (MgO) having its cubic ﹛110﹜ and ﹛111﹜ planes respectively parallel to the prism and basal planes of the hexagonal brucite lattice. Although the crystal-lographic relation between the parent brucite crystal and the resulting mag-nesium oxide crystallites is well known, the exact mechanism by which the reaction proceeds is still a matter of controversy. Goodman described the decomposition as an initial shrinkage in the brucite basal plane allowing magnesium ions to shift their original sites to the required magnesium oxide positions followed by a collapse of the planes along the original <0001> direction of the brucite crystal. He noted that the (110) diffraction spots of brucite immediately shifted to the positions required for the (220) reflections of magnesium oxide. Gordon observed separate diffraction spots for the (110) brucite and (220) magnesium oxide planes. The positions of the (110) and (100) brucite never changed but only diminished in intensity while the (220) planes of magnesium shifted from a value larger than the listed ASTM d spacing to the predicted value as the decomposition progressed.
