Abstract A compact ultrawideband (UWB) bandpass filter (BPF) is designed by harnessing the efficacy of a Pythagorean tree fractal shape stub-loaded resonator. The design inherently provides the passband transmission poles, which make it convenient to be used in wide passband filtering circuits. The number and the position of the resonating modes can be controlled by increasing the iterations of the Pythagorean tree, as analyzed using odd- and even-mode analysis. Design steps of the BPF are detailed. The designed UWB BPF takes up a small circuit area of (12.13 × 9.59) mm2. The proposed design is fabricated and measured to verify the simulated results. The stopband is extended up to 17.5 GHz with a maximum attenuation of 15 dB.

Education is about revealing possibility and exciting passions, empowering learners with the disciplinary expertise to meaningfully act on problematic contexts in which applying disciplinary knowledge is important. Toward this end, we have been using gaming methodologies and technologies to design curricular dramas that position students as active change agents who use knowledge to inquire into particular circumstances and, through their actions, transform the problematic situation into a known. Unlike more traditional textbooks designed to transmit facts or micro-stories, our focus is on building interactive experiences in which understanding core concepts, such as erosion or the idea of metaphor, and seeing oneself as a person who uses these to address personally meaningful and socially significant problems is valued. It is the explicit goal of this manuscript to communicate this power of educational videogames, as well as the design steps that we have been using to make this happen.

In the present paper, a comprehensive and simple in application design methodology to obtain a gas turbine working on recuperated, intercooled and reheat cycle utilizing existing gas turbines is presented. Applications of the proposed design steps have been implemented on the three existing gas turbines, with wide ranging design complexities. The results of evaluated aero-thermodynamic performance for these existing gas turbines with the proposed modifications are presented and compared in this paper. Sample calculations of the analysis procedures discussed, including stage-by-stage analysis of the compressor and turbine sections of the modified gas turbines, have been also included. All the three modified gas turbines were found to have higher performance, with cycle efficiency increase of 9% to 26%, in comparison to their original values.

Multi-Piece molds, which consist of more than two mold pieces, are capable of producing very complex parts—parts that cannot be produced by the traditional molds. The tooling cost is also low for multi-piece molds, which makes it an ideal candidate for pre-production prototyping and bridge tooling. However, designing multi-piece molds is a time-consuming task. This paper describes geometric algorithms for automated design of multi-piece molds. A Multi-Piece Mold Design Algorithm (MPMDA) has been developed to automate several important mold-design steps: finding parting directions, locating parting lines, creating parting surfaces, and constructing mold pieces. MPMDA constructs mold pieces based on global accessibility analysis results of the part and therefore guarantees the disassembly of the mold pieces. A software system has also been developed and successfully tested on several complex industrial parts.
