Monitoraggio topografico e fotogrammetrico della cupola del teatro Massimo
2012
L’articolo riporta i primi risultati di uno studio finalizzato al monitoraggio delle deformazioni della cupola del Teatro Massimo di Palermo provocate dalle dilatazioni termiche, con l’impiego di tecniche topografiche e fotogrammetriche integrate. In particolare, sono state utilizzate due stazioni totali robotizzate e sistemi di fotogrammetria digitale di elevata precisione. Per correlare gli spostamenti dei carrelli sui quali poggia la struttura in acciaio della cupola con i gradienti termici, sono state acquisite immagini termiche diversificate. L’obiettivo principale del lavoro consisteva nel confronto delle due tecniche di rilievo in relazione a misure di deformazione di entità molto ri…
Performance evaluation of robotic knowledge representation (PERK)
2012
In this paper, we explore some ways in which symbolic knowledge representations have been evaluated in the past and provide some thoughts on what should be considered when applying and evaluating these types of knowledge representations for real-time robotics applications. The emphasis of this paper is that the robotic applications require real-time access to information, which has not been one of the aspects measured in traditional symbolic representation evaluation approaches.
Symbolic and conceptual representation of dynamic scenes: Interpreting situation calculus on conceptual spaces
2001
In (Chella et al. [1,2]) we proposed a framework for the representation of visual knowledge, with particular attention to the analysis and the representation of scenes with moving objects and people. One of our aims is a principled integration of the models developed within the artificial vision community with the propositional knowledge representation systems developed within symbolic AI. In the present note we show how the approach we adopted fits well with the representational choices underlying one of the most popular symbolic formalisms used in cognitive robotics, namely the situation calculus.
ChatOps paradigmas izmantošana darba vidē
2018
Līdz ar tehnoloģijas attīstību un ikdienā darbā izmantoto rīku skaita palielināšanos, ir nepieciešams veids, kā vieglāk kontrolēt izstrādes procesus, izsekot serveru un kompilāciju statusus un kā uzlabot komunikāciju starp izstrādes komandām. Galvenaie darba uzdevumi ir novērtēt ChatOps lietojamību, kā izstrādes procesu metodoloģiju, kā šī paradigma tiek īstenota darba vidē un kādi ir šīs paradigmas lietošanas ieguvumi un izaicinājumi. Kā arī svarīgi ir noskaidrot, kādi ChatOps risinājumi eksistē un kā tie atšķiras viens no otra. Bakalaura darbā ir izpētīts, kas ir ChatOps programmēšanas paradigma, kā šī paradgima radusies, kādi ir izaicinājumi, ar ko var sastapties, ieviešot ChatOps darba …
Robotizētu procesu automatizācijas risinājumu piegāde
2019
Bakalaura darba mērķis ir izanalizēt un pētīt programmatūras piegādes specifiku un tās darbības izolācijas paņēmienus, kā arī pētīt un salīdzināt gan maksas, gan atvērtā pirmkoda robotizētu procesu automatizācijas platformu sniegtās iespējas un piegādes īpatnības. Bakalaura darbā sākotnēji tiek pētīts programmatūras piegādes process un šī procesa automatizācija, izvērtējot automatizēto risinājumu prasības un ieguvumus. Tālākajā darba gaitā tiek izpētīta piegādātās programmatūras izolācija, izvērtējot iespējamo variantu pozitīvās un negatīvās iezīmes. Turpmākajā darba gaitā tiek pētītas gan atvērtā pirmkoda, gan maksas robotizētu procesu automatizācijas izstrādes platformas, izvērtējot to sn…
COEDU-IN Project: an inclusive co-educational project for teaching computational thinking and digital skills at early ages
2021
Learning to program is the new literacy of the 21st century. Computational thinking, closely related to programming, requires thinking and solving problems with different levels of abstraction and is independent of hardware devices. The early childhood education stage provides teachers with the opportunity to lay the foundations for a comprehensive quality education using innovative tools and technologies. Educational robotics in early childhood education becomes a tool that facilitates the acquisition of knowledge to children, playfully, based on the principles of interactivity, social interrelationships, collaborative work, creativity, constructivist and constructionist learning, and a st…
Assessing the efficacy of direct conservation interventions: clutch protection of the leatherback marine turtle in the Dominican Republic
2014
AbstractThe beaches of Jaragua National Park in the Dominican Republic are the country's last known major nesting site for the leatherback marine turtle Dermochelys coriacea. This nesting aggregation is threatened by widespread illegal egg take, and clutch relocation and artificial incubation have been carried out as protection measures since 1974. We assess the efficacy of such efforts and investigate how artificial incubation may be influencing the success and sex ratios of clutches. We compare hatching success, incubation duration and embryo mortality in in-situ clutches (n = 43) with those incubated artificially at sites in the east and west of the Park (n = 35 and n = 31, respectively)…
Do robots complement or substitute for older workers?
2021
Abstract The impact of robotization on labor market outcomes has been recently empirically investigated along several directions, including employment, wages and labor productivity. This work contributes to this literature by looking for heterogeneous effects of robots on the workforce, analyzed by age cohorts. Relying on a panel of data from IFR (2019) and EU KLEMS (2009) over the years 1994–2005, we find consistent evidence of higher complementarity between robots and older workers (hours worked by employees aged 50 and over), and a greater substitutability among robots and younger cohorts of the labor market. These findings are robust to age group disaggregation and specific capital pric…
Operation management in reconfigurable manufacturing systems: Reconfiguration for error handling
2006
Abstract Reconfigurable manufacturing systems offer quick adjustment of production capacity and functionality in response to unpredictable market changes as being systems designed at the outset for rapid change in system configuration, its machines and controls. During the production process, out-of-ordinary events occur dynamically and unpredictably both at the system (machine breakdowns, change in job's priorities, etc.) and at the cell level (tool failures, robot collisions, etc.). Such exceptions interrupt the production process by causing errors in the schedule plan (system level) or in the task plan (cell level). Error handling is the policy meant for reacting to errors caused by the …
Dynamic analysis of a five degree of freedom robotic arm using MATLAB-Simulink Simscape
2021
In this paper, a dynamic analysis for a 5 degree of freedom (DOF) robotic arm with serial topology is presented. The dynamic model of the robot is based on importing a tri-dimensional CAD model of the robot into Simulink®-Simscape™-Multibody™. The dynamic model of the robot in Simscape is a necessary and important step in development of the mechanical structure of the robot. The correct choice of the electric motors is made according to the resistant joint torques determined by running the dynamic analysis. One can import complete CAD assemblies, including all masses, inertias, joints, constraints, and tri-dimensional geometries, into the model block. The first step for executing a dynamic …
