Methodology for energy demand reduction of potato cold storage process
In order to maintain the quality of the potatoes over time, it is necessary to store them under certain storage conditions, which minimize losses both of quality and product, preferably without using chemical treatments. ... -
Influence of maintenance actions in the drying stage of a paper mill on CO2 emissions
Greenhouse gases from industrial activities have become a global problem. Emissions management is being developed to raise awareness of the importance of controlling pollution in general and atmospheric emissions in ... -
Auxiliary consumption: a necessary energy that affects thermoelectric generation
Waste heat recovery can apply to a wide range of applications, from transportation, or industries to domestic appliances. Thermoelectric generation technology applied to those cases could produce electrical energy and thus ... -
Symbolic multibody methods for real-time simulation of railway vehicles
In this work, recently developed state-of-the-art symbolic multibody methods are tested to accurately model a complex railway vehicle. The model is generated using a symbolic implementation of the principle of virtual ... -
Kinematic design of a new four degree-of-freedom parallel robot for knee rehabilitation
Rehabilitation robots are increasingly being developed in order to be used by injured people to perform exercise and training. As these exercises do not need wide range movements, some parallel robots with lower mobility ... -
Characterization of two iron bullets from the royal ammunition factory of Eugi (Spain)
In this work, a comparative analysis of two iron bullets found in The Royal Ammunition Factory of Eugi in Navarra (Spain) was performed. Both bullets presented a spherical shape with a relatively good state of preservation, ... -
