As we ve come to expect, the judging for Design Expo 2021 was very close, but the official results are in. More than 1,000 students in Enterprise and Senior Design showcased their hard work on April 15 at Michigan Tech’s second-ever, fully virtual Design Expo.
Teams competed for cash awards totaling nearly $4,000. Judges for the event included corporate representatives, community members and Michigan Tech staff and faculty. The College of Engineering and the Pavlis Honors College announced the award winners below on April 15, just after the competition. Congratulations and a huge thanks to all the teams for a very successful Design Expo 2021.

Abstract
Nowadays, humans are suffering from chronic cardiovascular diseases, including Congenital Heart Defect (CHD). These diseases have far-reaching consequences, such as disruption of the daily life of humans by reducing their ability to perform daily routines. This problem is due to impaired cardiac pumping capability. The present numerical simulation studied the effects of CHDs on pressure drop and AWSS. Numerical calculation of non-Newtonian blood flow parameters, including power-law indices and the Reynolds number, were also investigated. To construct a 3D model of CHDs, an OSS program using DICOM and MRI was used. Besides, the vessel wall was assumed as solid. The non-Newtonian blood flow was assumed as a laminar flow with the slip boundary conditions at the vessel wall. AWSS, pressure drop, and dimensionless heat transfer coefficient are directly correlated with power-law indices, Reynolds number, and constant heat flux boundary conditions of the body. CHDs increased veloc
Abstract
Caving process is a complex dynamic phenomenon influences safety and productivity of coal longwall mining. It improves safety due to reduction of load on support, face convergence and abutment stresses. Proper caving with respect to the quality and time of occurrence ensures continuity of operation and subsequently, the productivity of coal extraction. Therefore, a reliable prediction of strata behaviour and its caving potential are imperative in design of longwall projects. This paper presents a hybrid probabilistically qualitative–quantitative model to evaluate cavability of immediate roof and to estimate main caving span in longwall mining by combining empirical model and numerical solution. For this purpose, numerical simulation was incorporated to Roof Strata Cavability index (RSCi) as summation of ratings for nine significant parameters. Distinct element code was used to simulate numerically main caving span corresponding to various RSCi classes probabilistically. T
