The small manufacturing company specializes in manufacturing of ear molds for hearing aids. Each ear mold is custom made for every individual patient. Today the manufacturing process is 100% manual and requires very skilled labor. To improve this process and introduce modern technology the Company contacted Center for Applied Research in Engineering and Science at Robert Morris University (RMUC...

An efficient manual micro assembly is a critical step in micro production. For a human operator, the manual assembly of miniature products presents a particular challenge. Amongst the challenges present in manual micro assembly are inadequately large human forces which increase the risk of damaging sensible products as well as the operator‟s limited capability of executing fine precision moveme...

Introduction: This in vitro study investigates the marginal and internal fit of indirect class II composite restorations. Two different processes for chair-side restorations were compared. In group A, the restorations were fabricated using CAD/CAM technology (Cerec, Sirona, Germany, Bernsheim) and in group B they were made by hand (GrandioSO Inlay System, VOCO GmbH, Germany, Cuxhaven). Methods:...

The main problem with modern quality control of sound speakers is that the process is conducted manually. This manual checking of the quality of sound speakers is time consuming. In order to find an automated way of doing this, this paper presents an intelligent system for automated quality control in sound speaker manufacturing, which fuses Fractal Dimension (FD) into Artificial Neural Network...

Scheduling is an important tool for manufacturing and engineering, where it can have a major impact on the productivity of a process (Min et al., 2009). In manufacturing, the purpose of production scheduling is to minimize the production time and costs, by informing a production facility when to make, with which staff, and on which equipment (Zhu et al., 2011). Nowadays, it is possible to obser...

The main objective of this paper is to report on the findings of an empirical study on the determinants of innovativeness in manufacturing firms. The empirical study covers 184 manufacturing firms located in the Northern Marmara region of Turkey. The types of innovation are taken as product, process, marketing and organizational innovations as suggested in the Oslo Manual 2005 published by OECD...

Variations exist in the manual preparationand delivery of cement during primary total hip arthroplasty. The incorporation of a power source may standardize cement mantle manufacturing. This study prospectively compared the use of a new power-operated polymethylmethacrylate vacuum mixing and delivery system to a commonly used manually powered industry standard. The study did not reveal a signifi...
