Curricula framework for a digital transformation master's in science and engineering
(Journal of Physics: Conference Series, 2021-06-09)
Digital transformation is an interdisciplinary work that has the objective to analyze data in real-time for better decision making, where it involves the modeling and the simulation of physical-mathematical and social ...
Analysis of the emotions in a multi-robot system in emergent contexts
(Cybernetics and Systems, 2021-01-12)
In this paper, we propose an emotional model for robots in a multi-robot system, in order to allow emerging behaviors. The emotional model uses four universal emotions: anger, disgust, sadness, and joy, assigned to each ...
Microservices backlog A genetic programming technique for identification and evaluation of microservices from user stories
(IEEE Access, 2021-08-20)
The microservice granularity directly affects the quality attributes and usage of computational resources of the system, determining optimal microservice granularity is an open research topic. Microservices granularity is ...
On the relationship between technical debt management and process models
(IEEE Software, 2021-02-10)
—As technical debt (TD) potentially occurs as a result of poor decisions that affect
software development tasks, one might expect that practitioners following different process
models, such as agile, hybrid or traditional, ...
Technical debt payment and prevention through the lenses of software architects
(Information and Software Technology, 2021-12)
Context:
Architectural decisions are considered one of the most common sources of technical debt (TD). Thus, it is necessary to understand how TD is perceived by software architects, particularly, the practices supporting ...

Numerical and Experimental Analysis of the Potential Fuel Savings and Reduction in CO Emissions by Implementing Cylinder Bore Coating Materials Applied to Diesel Engines
(Lubricants, 2021-02-18)
Currently, internal combustion engines contribute to the problem of global warming due
to their need to use products derived from fossil resources. To mitigate the above problem, this study
proposes the use of coatings ...
Influence of compression rings on the dynamic characteristics and sealing capacity of the combustion chamber in diesel engines
(Lubricants, 2021-03-02)
Internal combustion engines are widely implemented in several applications; however,
they still face significant challenges due to the sealing capacity of the compression rings. Gas leakage
through the crankcase, also ...
Analysis of the characteristics of combustion, emissions, and energy efficiency of blends of heptanol with pure diesel fuel in compression ignition engine(Article)
(2021-09)
The objective of this research is to study the influence of the heptanol content in conventional diesel fuel in different proportions for the evaluation of the combustion parameters, emissions, and energy efficiency. For ...
Performance, Emission, and Economic Perspectives of a Diesel Engine Fueled with a Mixture of Hydroxy Gas and Biodiesel from Waste Palm Cooking Oil
(International Review of Mechanical Engineering, 2021)
This investigation experimentally examines the influence of hydroxy gas fumigation in a diesel engine fueled with a biodiesel blend derived from waste palm cooking oil (B10). For the experimental tests, a fixed rotation ...
