Event Visualization and Trajectory Tracking of the Load Carried by Rotary Crane

Tracking the trajectory of the load carried by the rotary crane is an important problem that allows reducing the possibility of its damage by hitting an obstacle in its working area. On the basis of the trajectory, it is also possible to determine an appropriate control system that would allow for the safe transport of the load. This work concerns research on the load motion carried by a rotary crane. For this purpose, the laboratory crane model was designed in Solidworks software, and numerical simulations were made using the Motion module. The developed laboratory model is a scaled equivalent of the real Liebherr LTM 1020 object. The crane control included two movements: changing the inclination angle of the crane’s boom and rotation of the jib with the platform. On the basis of the developed model, a test stand was built, which allowed for the verification of numerical results. Event visualization and trajectory tracking were made using a dynamic vision sensor (DVS) and the Tracker program. Based on the obtained experimental results, the developed numerical model was verified. The proposed trajectory tracking method can be used to develop a control system to prevent collisions during the crane’s duty cycle.

Heritage Preservation as Strategy for Recomposing Conflict Territories

Heritage admits diverse readings depending on different territorial spaces, contexts, and knowledge fields. The relation between Heritage and the social contexts is one of these knowledge areas. But Heritage accepts a dual perception as a cultural reflection. It may be considered either as the origins of the conflicts or the engine for recomposing disrupted territories. The paper proposes a reflection on the topics related to conflict territories and the roles currently played by Cultural Heritage. The recomposition of conflict territories is based on a continuous intercultural approach with important contributions from human rights, genders equality, intercultural dialogue perspectives and the fact of taking heritage as a territorial stabilization factor. The paper presents specific practical cases in the Eastern Mediterranean region where actions on Heritage religious elements collide with the national sovereign of the respective current countries. A comparative study among these different actions proves that the initial clashes can be progressively transformed into strategies able to become the future guideline for the resolution of heritage regional conflicts. These conflicts reflect two discourses: political (with strong links between national identity and religion) and scientific (with a clash between static concept and dynamic vision) where objects interact with the visitors.

Missing links: the functional unification of language and memory (L∪M)

The field of neurocognition is currently undergoing a significant change of perspective. Traditional neurocognitive models evolved into an integrative and dynamic vision of cognitive functioning. Dynamic integration assumes an interaction between cognitive domains traditionally considered to be distinct. Language and declarative memory are regarded as separate functions supported by different neural systems. However, they also share anatomical structures (notably, the inferior frontal gyrus, the supplementary motor area, the superior and middle temporal gyrus, and the hippocampal complex) and cognitive processes (such as semantic and working memory) that merge to endorse our quintessential daily lives. We propose a new model, "L∪M" (i.e., Language/union/Memory), that considers these two functions interactively. We fractionated language and declarative memory into three cognitive dimensions, Embodiment-Formulation-Internalization, that communicate reciprocally. We formalized their interactions at the brain level with a connectivity-based approach. This new taxonomy overcomes the modular view of cognitive functioning and reconciles functional specialization with plasticity in neurological disorders.
