Mathematical Problems

In this chapter, the authors provide the simultaneous applications of numerical and mathematical methods for engineers. The best way to ignite the fire of curiosity in the student is the validation of their ideas and learning. Specially, the engineering students learn best when they are prompted by problems. This can be achieved through the validation of their analytical results with experimental. Therefore, the scope of the present work is to synchronize of the above-mentioned two domains (numerical, experimental). Furthermore, we have approached numerical methods from an experimental perspective. Mathematical methods are techniques by which mathematical problems are developed so that these can be solved with arithmetic operations. Although, there are many forms of numerical methods, they possess one common characteristic: they invariably call for large numbers of tedious arithmetic calculations. This work intends to relate the theoretical understanding with the real world problems.

Blast Effect

Building protection on our century is very important because of the terrorist attacks. The old buildings in Europe aren’t enough strong again blast loads. Nowadays we know many different explosives and theirs effects of walls and human bodies. The detonation caused blast effect provokes building damage and fragmentation effects. The explosion caused damages, parts of bricks and fragments produce other secondary damage in other buildings and human bodies.It can’t protect the historical and old buildings by new walls and fences because of the cityscape. It needs to find new possibilities to improve the buildings resistance again blast effects. It needs a effectively thin and strong materials to reinforced the buildings walls. The new materials innovated by material science can be good solution for this project. These materials usually composites likes syntactic foams, spherical shells or carbon fields reinforced composites.

The standards for mathematical practice describe varieties of expertise that mathematics educators should develop in their students, including NCTM process standards (problem solving, reasoning and proof, communication, representation, and connections), NRC's report “Adding It Up” (adaptive reasoning, strategic competence, conceptual understanding, procedural fluency, and productive disposition), common core state standards in mathematics (ICT application) to support mathematics teaching and learning. There is a need to provide effective ways that technology can be integrated into mathematics classrooms. Mathematical methods and techniques are typically used in engineering and industrial fields. It can also become an interdisciplinary subject motivated by engineers' needs. Mathematical problems in engineering result in rigorous engineering application carried out by mathematical tools. Therefore, a solid understanding and command of mathematical knowledge is very necessary. This chapter presents the introduction of currently available ICTs and their application of to create e-learning environments to prepare for the students' future engineering education.

Minor Losses

Determining of minor losses coefficient is very complicated problem. Analytical methods are often very difficult and experimental methods are very expensive and time-consuming. Consequently, the use of numerical methods seems to be a good solution, but there are no publications describing this issue. Therefore, the paper is describing the numerical method of determining the minor loss coefficient ξ on the example of elbows with circular cross-section.

Knowledge Graphs

The task of entity alignment between knowledge graphs aims to find entities in two knowledge graphs that represent the same real-world entity. Recently, embedding-based models are proposed for this task. Such models are built on top of a knowledge graph embedding model that learns entity embeddings to capture the semantic similarity between entities in the same knowledge graph. We propose to learn embeddings that can capture the similarity between entities in different knowledge graphs. Our proposed model helps align entities from different knowledge graphs, and hence enables the integration of multiple knowledge graphs. Our model exploits large numbers of attribute triples existing in the knowledge graphs and generates attribute character embeddings. The attribute character embedding shifts the entity embeddings from two knowledge graphs into the same space by computing the similarity between entities based on their attributes. We use a transitivity rule to further enrich the number of attributes of an entity to enhance the attribute character embedding. Experiments using real-world knowledge bases show that our proposed model achieves consistent improvements over the baseline models by over 50% in terms of hits@1 on the entity alignment task.

Understanding the real-world issues in the global industry is one of the ways of enhancing the learning experience of engineering students. This paper describes such an experience. This was a collaborative weld design project between Auburn University, Auburn, Alabama, Indian Institute of Technology (IIT), Madras, India and Bharat Heavy Electricals Limited (BHEL), Tiruchirappalli, India. The main problems BHEL faced were (1) Inspection time of the welds, (2) Inaccessibility of the welds, and (3) Detection of kissing bond or pasty weld. Three possible solutions to these problems were identified by the practitioners. In order to bring this real-world issue into engineering classrooms, the authors developed a case study. The authors also developed a multimedia CD-ROM which brings the problem live into class rooms using video, audio and pictures. This case study has been tested with mechanical engineering students. The majority of the students found the use of case studies to be beneficial, particularly because of the group work and applicability to real life situations. The details of the case study and its implementation in an engineering class room at Auburn University are discussed in the paper.

Most of the engineering courses focus more on theory and very little on hands-on, project-based learning in the classroom. Integration of real-world engineering problems and applications in lower division engineering courses will produce engineering students, who will be technically sound and be able to execute and manage real-world projects, when they will do senior design projects in their final year of engineering study. To overcome the engineering design challenges we have developed iHOP (Ingenieŕia Hands on Project) and integrate it with our lower division engineering courses. iHOP has been developed to emphasis the design component at the University of Texas at Brownsville (UTB) Engineering Physics curriculum and the project is now an integral part of Introduction to Engineering class. The iHOP project is one that is challenging, fun, requires teamwork, associated with the engineering material being studied, low cost, and doable in a limited amount of time. The experience from iHOP project motivates our freshman students to choose a better senior design project in senior year of their college career. The objectives of the iHOP projects are — to have students develop teamwork skills, and to teach students basic engineering design concepts in a complementary format to the traditional lecture. Various techniques related to team selection, encouraging teamwork, incorporation of engineering topics, keeping costs down, project results presentations, and gathering feedback from students will also be presented in this paper. Integrating iHOP Project with Introduction to Engineering class helped us to improve our retention effort in the engineering department.

Reduction Methods

Prejudice researchers have proposed a number of methods to reduce prejudice, drawing on and, in turn, contributing to our theoretical understanding of prejudice. Despite this progress, relatively few of these methods have been shown to reliably improve intergroup relations in real-world settings, resulting in a gap between our theoretical understanding of prejudice and real-world applications of prejudice-reduction methods. In this article, we suggest that incorporating principles from another field, social marketing, into prejudice research can help address this gap. Specifically, we describe three social-marketing principles and discuss how each could be used by prejudice researchers. Several areas for future research inspired by these principles are discussed. We suggest that a hybrid approach to research that uses both theory-based and problem-based principles can provide additional tools for field practitioners aiming to improve intergroup relations while leading to new advances in social-psychological theory.
