Simulación de estaciones de trabajo ergonómicamente diseñadas para inspeccionar lentes de contacto
(Polytechnic University of Puerto Rico, 1994-06)
In this project we describe the ergonomic design of workstations for the inspection of contact lenses. MANNEQUIN, a simulation program, was used for the evaluation and proper design. The main objective of 111s project is ...
Método analítico para determinar concesiones y análisis de rendimiento
(Polytechnic University of Puerto Rico, 1994-06)
We developed an analytical method to determine allowances and performance ratings based on human physiology. The theory about the human capacity to do work is analogous to the graph of steel fatigue used for structural ...

(Polytechnic University of Puerto Rico, 1994-06)
A local pharmaceutical company has to reduce the number of complaints from customers who receive its products in broken or cracked glass bottles. In this paper we discuss an experiment to establish parameters to guarantee ...
A utility for Netware: REMOTE
(Polytechnic University of Puerto Rico, 1994-06)
We used the C language code to develop a utility that allows two or more workstations connected to the same physical network running the network operating system Netware to communicate and perform remote operations. The ...
Design of an experiment for injection blow molding
(Polytechnic University of Puerto Rico, 1994-12)
This research was requested by the quality control engineer of a company manufacturing plastics products such as bottles and caps. These products are manufactured with polyethylene and polipropylene resin, using two molding ...
