The church of San Francesco della Scarpa is a church in the historic center of Lecce (Southern Italy), so called in the 16th century when the minor friars who lived in the destroyed convent of Santa Maria del Tempio were divided into conventual and observant: the former wore shoes unlike the seconds. The church has had static stability problems in recent years. In order to understand the causes, a series of findings have been undertaken with the use of integrated non-destructive methodologies. Ground Penetrating Radar (GPR), seismic tomography (ST), passive seismic (PS) and laser scanning...

In this paper we propose an experimental case of the joint use of ground penetrating radar (GPR) and time domain reflectometry (TDR) for the estimation of the dielectric permittivity of several type of wood. In particular, the well known method of the diffraction curves is compared with the results of an auto-focussing strategy based on a linear microwave tomographic approach and with a TDR measurement. The effect of the actual offset between the antennas is accounted for too.

LorisQ is a cloud-based equipment management platform built on the understanding that measuring equipment maintenance is all about exchange of data and information between clients (equipment users) and service providers (calibration labs and others). Scaleability and flexible design is essential precondition for its global use by teams of all types and sizes: testing and calibration labs, manufacturing SMEs, corporate labs, maintenance, quality and purchasing departments, universities, hospitals and small maintenance service providers. Its client-provider interconnected workflow happening in...

Witnessing the unprecedented scale and speed of industry transformation due to digitization in general and the emergence of smart solutions in all aspects of manufacturing in particular, it is well justified to deal with the question of what production of the future will look like. How intelligent will it be when the hard challenges and disruptive effects of the changes will be overcome, and what are the chances to meet the critical requirements of collaboration and cooperation, flexibility and competitiveness? What are the technological and management tools to avoid being stuck in the...

This paper focuses on giving a comparison and review about two of the most popular Predetermined Motion Time System (PMTS) analysis and improvement methods: MTM and BasicMOST. Methods Time Measurement (MTM) is the most popular PMTS as it is the oldest one, while Maynard’s Operation Sequence Technique (MOST) was created and is based on MTM, therefore being the second most popular PMTS method. Both methods are used to analyses human motions during work activity, and they are attempting to improve and optimize a given process, to be as effective as it is possible. MTM is more precise,...

The local plastic deformation of a sheet, using a unique tool by different controlled path strategies with the absence of punch and die is called Single Point Incremental Forming (SPIF). It is an environmental friendly sheet forming process compared to stamping, where the manufacturing and disposal of dies are creating a huge environmental footprint. In SPIF, the forming tools are mainly kind of a metal spike with a spherical or flat end on top of it, where the diameter of the tool tip is 10 mm in average. In this study, the effects of different parameters of SPIF on the hardness of...

Contactless braking methods (with capability of energy recuperation) are more and more widely used and they replace the traditional abrasive and dissipative braking techniques. In case of rotating motion, the method is trivial and often used nowadays. But when the movement is linear and fast alternating, there are only a few possibilities to break the movement. The basic goal of research project is to develop a linear braking method based on the magnetic principle, which enables the efficient and highly controllable braking of alternating movements. Frequency of the alternating movement can...

The acoustic noise level in the interior is one of the quantities specified by a standard and is subject to audits to ensure a comfortable living environment. Currently, the noise level audits are performed manually by a skilled operator, who estimates the floor plan and uses it to calculate the control points location in which the measurement is performed. We propose to automate the computation by formulating an optimization problem for which we designed an algorithm. Algorithm computes the solution that satisfies all constraints specified in the standard, for example, the minimum distance...

This paper proposes a methodology to verify composite products reliability through its life time using a probabilistic Arrhenius model. It will present the challenge that automotive industry faces and study the potential improvement to be considered in order to improve the reliability during the design and validation phases. The formulas developed in this research permit to set up an accelerated test at the strict necessary needs. The goal is the integration of the variability from Energy of activation (Ea), Test Conditions (Test Bench Temperature Tb) and a dispersion from usage temperatures...

This paper analyses the effect of variability of metrological characteristics of a set of low-cost MEMS accelerometers on the calculation of typical features used in condition monitoring of automatic production lines. The knowledge of the contribution of the variability of sensor metrological characteristics to the final accuracy of features is expected to be interesting when networks of low-cost sensors are used or in cases the spread of their characteristics is high, due to a mass production without single calibration. The real variability of the sensor’s characteristics has been...
