INTERNET BASED DEVELOPMENT OF AN OPEN SOURCE LOW-COST CNC
2006
In this paper we show how to realize a low-cost numerical system, based on an “open source” software called EMC (Enhanced Machine Control). First, we assembled a low cost CNC workstation with a remote control by means of an online computer with a webcam, as an example of the software's potentiality. Moreover, we translated a graphical user interface (AXIS), in co-operation with the international development community, in order to improve its userfriendliness.
Enhanced nanoscopy of individual CsPbBr3 perovskite nanocrystals using dielectric sub-micrometric antennas
2020
We demonstrate an efficient, simple, and low-cost approach for enhanced nanoscopy in individual green emitting perovskite (CsPbBr3) nanocrystals via TiO2 dielectric nanoantenna. The observed three- to five-fold emission enhancement is attributed to near-field effects and emission steering promoted by the coupling between the perovskite nanocrystals and the dielectric sub-micrometric antennas. The dark-field scattering configuration is then exploited for surface-enhanced absorption measurements, showing a large increase in detection sensitivity, leading to the detection of individual nanocrystals. Due to the broadband spectral response of the Mie sub-micrometric antennas, the method can be e…
Optimization of Long-Run Average-Flow Cost in Networks With Time-Varying Unknown Demand
2010
We consider continuous-time robust network flows with capacity constraints and unknown but bounded time-varying demand. The problem of interest is to design a control strategy off-line with no knowledge of the demand realization. Such a control strategy regulates the flow on-line as a function of the realized demand. We address both the case of systems without and with buffers. The main novelty in this work is that we consider a convex cost which is a function of the long-run average-flow and average-demand. We distinguish a worst-case scenario where the demand is the worst-one from a deterministic scenario where the demand has a neutral behavior. The resulting strategies are called min-max…
Reviving earthen architecture in Palestine: The added significances of the building sustainability and an opportunity for the future
2016
Several attempts have emerged recently in Palestine aiming to find an economical-environmental alternative building material beside the widely-used natural stone as a main building material, due to some factors related to the cost and the negative effects of stone mining areas on the local environment. Similar attempts had a certain response to the peculiar social needs and economic situation there. The efforts led to revive earthen architecture on organizational and individual levels, producing a certain number of earthen buildings in the last few years. In order to evaluate the appropriateness of earth as an alternative raw material in Palestine, the paper outlines the general advantages …
An Analytic Hierachy Process for Ranking Operating Costs of Low Cost and Full Service Airlines
2009
This paper develops an application of the analytic hierarchy process to rank the operating cost components of full service and low cost airlines. It takes into account the financial balance sheets and answers to a questionnaire submitted to the managers of selected airlines. The results suggest that the analytic hierarchy process can be appropriately used to obtain the ranking of the costs taking into account different views: financial, management and operative. Rental, office equipment and other supplies costs show the highest importance in the cost ranking, both for full services and low cost airlines. The robustness of the results is tested by Monte Carlo analysis.
3D digitization of transparent objects by polalization techniques in IR & by triangulation in UV
2011
Two non-conventional methods for the 3D digitization of transparent objects via non-contact measurement are reported in this thesis. 3D digitization is a well acknowledged technique for opaque objects and various commercial solutions based on different measurement approaches are available in the market offering different types of resolution at different prices. Since these techniques require a diffused or lambertian surface, their application to transparent surfaces fails. Indeed, rays reflected by the transparent surface are perturbed by diverse inter-reflections induced by the refractive properties of the object. Therefore, in industrial applications like quality control, the transparent …
Regenerating Landscape from Resilient Citizens: Parco Uditore, Three Years of "Low Cost Landscape"
2016
In the always surprising capital of Palermo, a hidden garden of opuntia indica relics has been discovered again after decades of oblivion, due to the work and the unceased promotion made by a huge group of citizens, students, teachers and volunteers. In this 9 hectares area owned by the regional government of Sicily since a long time ago (1963), the remains of a dense opuntia plantation characterizes a green forgotten area, casually survived to the building growth of Palermo. Along three decades (1963‐1993) after being a military underground stowage plant for fuel in WWII, the Fondo Uditore is still a full opuntia place, where the sweet fruits and the green and prickly “leaves” where sold r…
Progettare un paesaggio low cost
2012
Nelle maggiori città europee e in diversi casi nel resto del mondo la tutela, la valorizzazione e la cura partecipata del verde pubblico sono pratiche ormai consolidate da decenni; esiste da tempo una consapevolezza matura del ruolo determinante che le aree verdi svolgono nell’ambito di uno sviluppo sostenibile della civiltà. Attraverso l’esperienza del recupero per la fruizione immediata di Fondo Uditore a Palermo, oggi si presenta anche per Palermo l’occasione di allinearsi a quella che, più che una tendenza, è una necessità riconosciuta e imprescindibile per garantire una migliore qualità della vita in ambito urbano. Qui, dove la recente storia urbanistica racconta decenni di colpevole n…
Una memoria agricola in un paesaggio low cost
2016
L'esperienza della trasformazione del paesaggio agrario tradizionale in un parco urbano partecipato a basso costo. Nella sorprendente Palermo, una città complessa, dove un paesaggio drammatico combatte giorno dopo giorno contro una città contemporanea di pietra e di cemento, un giardino nascosto di Opuntia viene scoperto ancora una volta dopo decenni di oblio, grazie ak lavoro e alla incessante promozione fatta da un gruppo di cittadini, studenti, professori e volontari.
Design and experimental characterization of a low-cost, real-time, wireless AC monitoring system based on ATmega 328P-PU microcontroller
2015
This paper describes the development and experimental characterization of a real-time, low-cost, wireless AC monitoring system based on ATmega 328P-PU microcontroller. The proposed system is composed by a main brain for the acquisition and the processing of the data measured by smart meters. From the experimental tests discussed in this work it is demonstrated that the proposed system can monitor, with adequate accuracy, the working cycles of electrical loads in order to evaluate its energy consumption.
