Design of an intravenous drug delivery device
(2004-05)
The use of intravenous implanted devices to deliver controlled drug dosage for the treatment of certain health problems is becoming more common as an alternative to regular injection procedures. This work proposes a ...
Fabrication and characterization of chitin-carbon nanotubes composites
(2015)
Most polymers by themselves have limitations due to their poor mechanical, thermal and
electrical properties compared with metallic and ceramic materials. Therefore, to expand
their range of applications these properties ...
Innovative vibration technique as a viable substitute for conventional three point bending fatigue testing
(2008)
Fatigue lifetime prediction of various materials under three-point-bending is generally limited to the long testing periods consumed and the economic inversion needed develop the test. The use of a vibration technique as ...
Analysis of conduction heat transfer in semi-infinite slabs and infinite quadrants with discrete heat generation sources using green's function integral methods
(2003)
The problem of steady state heat conduction in semi-infinite plates and infinite quadrants of constant thermal conductivity, with discrete heat generating sources and Dirichlet boundary conditions (temperature specified ...
Streamlined life cycle assessment of glass bottle end of life strategies in Puerto Rico
(2021-05-17)
In the following study, a streamlined life cycle assessment (SLCA) of different end-of-life strategies for repurposing or recycling glass bottles is modelled to compare the environmental impact of each strategy. This SLCA ...
Finite element analysis of unexpected failure of lake-ice under loads moving at critical velocity
(2012-07)
Through this work we predicted the unexpected failures of lake-ice under the effect of moving loads at critical velocity using finite element analysis. The main motivation was to solve the unexpected failure of the lake-ice ...
Effects of external conditions on the boundary layers of adjacent blades on a compressor cascade
(2018-12-12)
In commercial aircraft engines, improvements of 1% in overall engine efficiency represent millions of dollars in fuel savings and a considerable reduction of CO emissions. Analyzing, understanding and optimizing each process ...
Fabrication and characterization of sintered recycled glass designed for polluted soil filtering
(2014-07)
Soil pollution generates diseases, hunger, and agricultural problems. Porous recycled glass beds were produced to study the feasibility of using them for polluted soil filtering. This research discusses structural and ...
Bioelectric spectra characterization of individual cancer cells with electrochemical impedance spectroscopy
(2019-07-10)
In the field of Biomedical Science and Engineering, microfluidic systems have been used for the analysis of cellular structures at the micro and nano-scales. Predominantly, work in the field is geared towards multicell-multiarray ...
Metallic phase change materials (mPCMs) stability and compatibility analysis under repetitive melting/solidification cycles
(2020-07-24)
Metallic phase change materials (mPCMs) have been demonstrated as a
potential passive cooling solution for pulse power applications. The possibility of
integrating a metallic PCM directly on top of a heat source, reducing ...
