The Influence of Fruit Ripening Stage at Harvest and Storage Temperature on ‘Bianca di Bivona’ White Flesh Peaches
2015
‘Bianca di Bivona’ is a white-flesh peach cultivar, which ripens during the last week of July and the first of August. Its fruit are known because of their distinct flavor and aroma, which make them highly accepted, particularly in the local markets. However, nothing is known about their postharvest physiology and storage conditions. In order to investigate the effect of: (a) fruit ripening stage at harvest and, (b) storage temperatures, ‘Bianca di Bivona’ peaches were picked at mature-green, (60.0±1.3 N), and ripe stage (30.7 ± 2.1 N) determined by flesh firmness, and then stored at 0°C and 5°C (90% RH). Flesh firmness, total soluble solids, titratable acidity, weight loss and DA index, me…
Test-Retest Reliability of Task Performance for Golf Swings of Medium- to High-Handicap Players
2022
Background: Golf swing performance in medium- to high-handicap players must be reliably measured to use this variable in both research studies and in applied settings. Nevertheless, there are no studies published on this topic and test–retest evidence is only available for low-handicap players. The aim of this study was to determine the number of attempts necessary to obtain a reliable measurement protocol for swing performance variables in medium- to high-handicap players. Methods: Ten amateur players (55.67 (13.64) years, 78.4 (11.4) kg, 1.75 (7.95) m) took part in a test–retest study in two experimental sessions one week apart. In each one, fifteen swings with a six iron and a driver wer…
Business model innovation for the SDGs: Towards a performance measurement system
2019
Business model innovation can be a key element for realizing the transformation needed to accomplish the Sustainable Development Goals. However, literature on Sustainable Business Models still lacks quantitative-oriented approaches and tools supporting the implementation and assessment of business model innovations for sustainability. This study proposes an eight-phase performance measurement system supporting organisations in implementing, assessing and managing business model innovations aiming at contributing to the Sustainable Development Goals. The performance measurement system builds upon literature on business model innovation for sustainability, performance measurement and manageme…
Outlining the impact of intellectual capital accumulation and depletion processes on the performance of an insurance firm: a dynamic resource-based p…
2014
This paper aims to develop a conceptual framework on how Intellectual Capital (IC) accumulation and depletion processes are dynamically interrelated with firm performance. Such a framework makes explicit the relationships between policy levers, strategic resources, drivers, end-results and performance indicators through a Dynamic Resource-based perspective. Such an approach matches the Resource based perspective and the System Dynamics (SD) methodology. This paper argues that in order to explain a firm superior performance, it is not sufficient to look at the endowment of strategic resources in a given moment of time; it is instead required to investigate the dynamics of company strategic r…
Optical sensor for remote estimation of alcohol concentration in blood stream
2013
Abstract The purpose of this manuscript is to validate our recently developed novel optical approach for extraction of remote vibration sources as a successful technique to estimate the alcohol concentration in blood stream. This technique is based on the tracking of temporal changes of reflected secondary speckle patterns produced in human skin when being illuminated by a laser beam. Since the skin’s vibrations profile is changed due to the alcohol in the blood stream, the extraction of the vibration profile can be translated into the corresponding alcohol concentration values by means of defining several parameters acting as indicators for the presence of alcohol in the blood stream. We h…
Current characterisation for ultra low power wireless body area networks
2010
The emerging area of body area networks (BAN) imposes challenging requirements on hardware and software to achieve the desired lifetimes for certain devices such as long term medical implants. In this paper, we propose a novel approach to the measurement and characterisation of the energy consumption of BAN devices. The approach uses a low cost energy auditing circuit and addresses the problem of accurately measuring low-level current consumption. This new technique will allow precise and analytical measurements of systems and components in terms of energy. This will help circuit designers minimise power consumption in BAN devices. Software engineers might use this approach to validate and …
How to Use the DHT22 Sensor for Measuring Temperature and Humidity with the Arduino Board
2016
Abstract The objective of this paper is to achieve a functional system in terms of hardware and software, to measure temperature and humidity. Also, this system will allow to monitoring the time. In this, we use an Arduino board with interfacing a sensor placed in local environment to measure temperature and humidity. The paper aims to achieve the following goals: - achieving a functional system in terms of hardware and software that allows measuring and monitoring temperature, humidity and the time; - using a development board for the communication with the sensor and clock; - implementation a program that allows requirements.
Implementation and Experimental Tests of a Management System for MV/LV Distribution Grids
2019
The continuous monitoring of network power flows and the remote control of Distributed Generators and Energy Storage Systems are the essential elements to allow a full exploitation of Renewable Energy Sources and their real integration in distribution networks. Thus in the paper a management system is presented for load flow monitoring in MV/LV distribution network. Moreover, on the basis of calculated power flows, the management system is able to send control commands to DGs and ESSs, to vary their power production or power factor or eventually to disconnect them in order to maintain the network stability. The proposed solution was really implemented in the MV network of Ustica Island, dev…
The Computer Control Software for MAMI
1980
The computer control system of the Mainz Microtron is designed to keep track with the modular and step-by-step construction of the three accelerator stages. The system is up to now based on two loosely coupled HP1000 minicomputers, interfaced via CAMAC to the accelerator components and to the operator desk. The control software is divided into several layers of portable processes distributed to both computers. Communication between the processes, access to the data bank and the routing of CAMAC interrupts are handled via a message system which operates with symbolic addresses.
The Influence of Requirements in Software Model Development in an Industrial Environment
2017
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To do this, we have conducted an experiment in industry with 19 engineers of CAF (Construcciones y Auxiliares de Ferrocarril), which is a supplier of railway solutions. The experiment is a crossover design that analyzes efficiency, effectiveness, and perceived difficulty starting from a written spec…
