This paper applies reverse engineering on the Bresenham's line drawing algorithm [J. E. Bresenham, IBM System Journal, 4, 106–111 (1965)] for polygonal approximation of digital curve. The proposed method has a number of features, namely, it is sequential and runs in linear time, produces symmetric approximation from symmetric digital curve, is an automatic algorithm and the approximating polygon has the least non-zero approximation error as compared to other algorithms.

Engineering Concept

Most engineering design projects focus primarily on the engineering fundamentals. Studying the business case or manufacturability of a design is often left for other courses, if at all. To address this gap, an existing mechanical engineering course project was modified by embedding the interdependent entrepreneurial dimensions. In the past, junior engineering students developed a reciprocating air engines over two semesters. The modified project extended the engineering fundamentals into an entrepreneurial venture. To accomplish this, students were asked to propose an air engine toy for middle schoolers. The proposed toy had to be assembled, provide a learning opportunity, and demonstrate utility. The students had to ensure the product appealed to those interested in the STEM fields. The students, working in groups, created renders of the final product, assembly instructions, and a guided worksheet for the kids to explore the underlying engineering concept. The groups produced a website with a video pitching their toy concepts. This case study exemplifies how any engineering endeavor can be modified to capture a more holistic simulation of the profession.

Technical Museum is one of the most visited Museums in Zagreb (capital of Croatia). The museum presents scientific and educational centre in the field of technical sciences. The entire structure of the Museum is constructed as a timber structure and as such represents a rare existing example of the European engineering concept of expo-halls timber structures with large span (85m x 40 m) from the early 20 century. In this article overview of different NDTs that were performed in order to assess the structural performance of elements is given; moisture ratio and ultrasound investigations are carried out in situ in order to investigate timber condition. Based on the detected state of the structure reconstruction measures are presented.
