Visual-based Feedback Control of Casting Manipulation
2006
In this paper, we present a method to control casting manipulation by means of real-time visual feedback. Casting manipulation is a technique to deploy a robotic end-effector at large distances from the robot’s base, by throwing the end-effector and controlling its ballistic flight using forces transmitted through a light tether connected to the end-effector itself. The tether cable can also be used to retrieve the end-effector and exert forces on the robot’s environment. Previous work has shown that casting manipulation is able to catch objects at a large distance, proving it viable for applications such as sample acquisition and return, rescue, etc. In previous experiments, the position o…
UMTS radio networks
2006
Publisher Summary This chapter reviews the contributions to the UMTS radio network planning, with the optimization being provided from COST 273 and the real-time tuning, which is related to RRM. The results on UTRAN performance evaluation by the means of simulation tools are also discussed. The UMTS planning includes processes like: the propagation and traffic models, the aspects of parameter planning, and the automatic planning algorithms. An accurate ray-tracing model integrated in a UMTS-capable planning tool allows the radio network planner to reach optimal numbers for the BS deployment and configuration while meeting the service level requirements. Ray tracing can identify the problem …
A distributed architecture for autonomous navigation of robots
2002
The paper shows a distributed architecture for autonomous robot navigation. The architecture is based on three modules that are implemented on separate and interacting agents: the target recognizer, the obsta90cle evaluator and the planner. An adaptive genetic algorithm has been studied to identify mechanisms for reaching the target and for manipulating the 2-directions of the robot; the distributed architecture has been embedded in the DAISY (Distributed Architecture for Intelligent System). Experiments have been carried out using a LEGO intelligent brick.
A description model for regeneration through urban tourism in rural towns with underused historic real estate
2016
Il presente contributo propone un modello di descrizione (description model) che trova applicazione in una situazione reale di aiuto alla decisione posto dall'urbanista per lo sviluppo turistico delle città rurali nelle zone dell'entroterra siciliano. Il problema decisionale riguarda la città di Cianciana (AG), che negli ultimi anni si è resa protagonista di un particolare fenomeno di turismo internazionale. In particolare, proponiamo un quadro valutativo multicriteriale per la riqualificazione fisica ed economica del centro storico della città attraverso lo sviluppo del turismo. Il modello presentato, relativo a un problema decisionale di tipo descrittivo, è orientato a supportare i deciso…
Genetic variability and population structuring in the European Lanner Falcon Falco biarmicus feldeggii
2019
We analysed variation in 10 polymorphic microsatellites and a variable portion of control region of mtDNA in 24 specimens from 3 populations of European Lanner Falcon Falco biarmicus feldeggii living in Sicily, continental Italy and the Balkan area to assess species' genetic diversity and population structure in the poorly investigated range of this threatened subspecies. We considered also a dataset of previously published mtDNA sequences of the other Lanner Falcon subspecies and of Hierofalco subgenus members (F. cherrug, F. rusticolus and F. jugger) to outline the genetic variation in the region on a wide-ranging basis. Regard with mtDNA we identified 6 haplotypes from our 24 European La…
Increased interleukin-6 and C-reactive protein levels after instrumented lumbar spine fusion in older patients
2019
Purpose: Interleukin 6 (IL-6) and the acute phase C-reactive protein (CRP) blood concentrations after lumbar spine fusion may be affected by age. The purpose of this prospective observational study was to assess postoperative serum levels of pro-inflammatory IL-6 and CRP after instrumented lumbar spine fusion surgery. We hypothesized that older patients would have increased levels of IL-6 and CRP after surgery. Methods: IL-6 and high-sensitive CRP biochemical marker levels were measured before instrumented spinal fusion, and postoperatively at 1 and 3 days, 6 weeks, and 3 months. The 49 patients in this sample were divided into two groups: age ≤ 60 years (n = 23) and age > 60 years (n = 26)…
Dienasgrāmatas vizuāls un tekstuāls iekārtojums personai ar īpašām vajadzībām dzīves aktivitāšu organizēšanai
2014
Personai, kurai ir psiholoģiskas vai fizioloģiskas problēmas ir nepieciešams atvieglot savu dzīvi, jo ir grūtības uztvert un orientēties plašajā informācijas apjomā. Autore savā darbā vēlējās izpētīt, kādas ir iespējas izveidot dienasgrāmatu cilvēkiem ar īpašām vajadzībām, kurā būtu iekļauta pēc iespējas plašāka un detalizētāka informācija, kas būtu viegli uztverama, izmantojot vizuālo un tekstuālo noformējumu. Diplomdarba tēma – ,,Dienasgrāmatas vizuāls un tekstuāls iekārtojums personai ar īpašām vajadzībām dzīves aktivitāšu organizēšanai.” Darba mērķis: izpētīt dienasgrāmatu un ikonografikas dizaina pielietošanas variācijas un izveidot radošā darba projektu, kurā būtu apvienoti dienasgrām…
Comparative Analysis of Lanner and Peregrine Trophic Niche in the Mediterranean
2017
Predators are highly sensitive to availability and changes of their prey, which are limiting factors for successful reproductive performances. We studied the diet of the increasing Peregrine falcon (F. p. brookei) and the declining Lanner falcon (F. b. feldeggii) populations in Sicily. The two species coexist in the same habitats of this large Mediterranean island and require similar feeding resources. We described the type and diversity of prey taken by both species in order to understand whether differences in foraging ecology could explain their diverse population status. During 2014-2016, we collected prey remains and pellets in 15 Peregrine and 6 Lanner nests and we compared the curren…
Can planning be a research paradigm in architectural design?
1991
Abstract In the present paper we discuss the possible use of ‘planning’ ° to support architectural design. Architectural design is conceived as a process incorporating non-trivial subprocesses consisting of evolutionary sequences of drawings. The ‘planner’ can be viewed as a tool capable of managing the automatic development of formal descriptions of architectural objects, according to goals and constraints which are interactively assigned or removed by the designer. The main features of a ‘planner’ dedicated to architectural design are then put forward. The system has been implemented at the University of Ancona, Italy.
Is integration of Uncertainty Management and The Last Planner System a good idea?
2018
The Last Planner System (LPS) is a tool for project planning and control, and is an important contribution from Lean Construction. LPS focuses on scheduling, task coordination and time management. Uncertainty Management (UM) is a key element in Project Management, where uncertainty is the totality of opportunities (potential upsides) and risks (potential downsides). UM addresses all types of uncertainty (related to cost, time, quality, scope, safety, customer satisfaction, company reputation, etc.). The aim of UM is to exploit the opportunities and reduce the risks. Two construction companies involved in this research are working with both LPS and UM. One has extensive experience with LPS, …
