Trust enhancement of P2PSIP communication systems
2011
Today, peer-to-peer (P2P) session initiation protocol (SIP)-based communication systems have attracted much attention from both academia and industry. The decentralised nature of P2P might provide the distributed P2P communication system without help of the traditional SIP server. However, it comes to the cost of reduced trustworthiness and may cause security problems, e.g., privacy leaks, unpredictable availability, etc. In this paper, we investigate P2PSIP security issues and propose a subjective logic-based trust model that offers trust-based security services during P2PSIP session establishment. The main issues considered in this model include opinion calculation, opinion maintenance, d…
Producing Routing Systems Flexibly Using a VRP Metamodel and a Software Product Line
2012
Routing problems occur in a wide variety of situations. Due to the heterogeneity of cases we do not yet know how to manage the complexity of addressing all the relevant aspects in logistic planning and solving the variety of different problem types in a cost-efficient way. In the last decade, we have witnessed an emergence of systematic approach into managing variation within a set of related software systems. This paper presents an application of these advances from software engineering into vehicle routing: we suggest the construction of a higher-level (meta-) model of routing problems and the application of a software product line approach. The proposed approach results in a flexible pro…
Intelligent Energy Management System
2009
Energy management is nowadays a subject of great importance and complexity. It consists in choosing among a set of sources able to produce energy that will give energy to a set of loads by minimising losses and costs. The sources and loads are heterogeneous, distributed and the reaction of the system, the choice of sources, must be done in real-time to avoid power outage. The goal of this paper is to present a system able to self-regulate a heterogeneous set of power sources and loads organised as a coherent group of entities that is called micro-grid, in order to optimize several criteria such as: cost and efficiency. This system is based upon the Multi-Agent Systems paradigm. Each micro-g…
Interactive Gradually Generating Relevance Query Refinement Under the Human-Mediated Scenario in Multilingual Settings
2016
As opposed to query modelling, relevance generating interactive query refinement (QR) is a technique aimed at exploiting syntax variations of gradually extended, being removed or replaced with some other keywords query, which depending on the factors like e.g. the information resource, the database structure, or the keyword alignment, facilitates significantly the searching process. Therefore our motivation is to explore the dynamism of the precision trend depended upon the factors analyzed. For a couple of language pairs which constitute multilingual settings, we develop a user-centred framework that imposes distributed search optimization. Our data set contains variety of query types subm…
Quality determinants of avocado fruit consumption in italy. Implications for small farms
2018
In recent years there has been an increasing consumer interest towards tropical fruits due to the desire of consumers for healthy eating while experiencing new and exotic flavours. Within this consumer trend, avocado fruit presents great potential in order to meet the requirements desired by consumers due to its high nutritional value and particular quality characteristics. The aim of the present study is to understand which quality determinants influence consumers’ decision making to consume avocado fruit in Italy. In the literature, avocado is a fruit few investigate from a consumers’ quality perception perspective. Therefore, understanding consumer preference for avocado fruit may be con…
Good, safe and fair: Quality perception and consumer demand of Locally produced beef in Southern Italy
2017
The increasing concern amongst consumers regarding the safety and quality of the beef that they buy is the result of food scares that have characterized the beef market in the last two decades. These scares, together with environmental and ethical concerns, caused consumers to reflect upon the quality of the beef they eat. The aim of this paper is to identify which quality characteristics influence the incidence of local beef consumption on the total consumption of beef. It is assumed in this study that such choice is a response to a process of quality evaluation, which occurs combining specific quality attributes and socially constructed food quality criteria strictly linked to a socially …
Mass modelling by dimension attributes for mango (Mangifera Indica cv. Zebdia) relevant to post-harvest and food plants engineering
2016
Mass identification of mango fruits from their dimension attributes remains challenging. This is because of the unregulated shapes of these fruits. Therefore, this research aims at creating mathematical models that can demonstrate the relationship between the fruit‘s mass and dimension attributes. Hence, these models can be used in post-harvest engineering systems. The researchers used 100 mango fruits (Mangifera indica cv. Zebdia) to determine the mathematical relationship between the fruits‘ weight and dimension attributes. The researcher measured and photographed the dimensions of these fruits and processed the image captured for each fruit using a computer program to find the fruit‘s di…
Consumer Assessment on Sensory Attributes of Fresh Table Grapes Cv 'Italia' and 'Red Globe' after Long Cold Storage Treatment
2017
The impact of research that is being carried out into the relationship between food and consumers is progressively reinforced by continuous findings in literature confirming that consumers choose foods basing on their functional cognition and sensory perception, especially when buying fruit and vegetables. Therefore, it is important for table grape producers to be aware of consumers' concerns and preferences both, during the purchasing stage and after, during consumption at home, when experiential attributes have more importance. In both cases, sensory attributes play an important role in determining consumers’ purchase behavior of table grape. Table grapes cv ‘Italia’ and ‘Red Globe’ are p…
Quality Changes of Tropical and Subtropical Fresh-Cut Fruits Mix in Modified Atmosphere Packaging
2017
Application of passive modified atmosphere packaging (MAP) for shelf life extension of mixed pineapple slices, mango pieces and orange segments, was evaluated. Fruits of Ananas cv ‘Gold’, Mango cv ‘Keitt’ and Orange cv ‘Washington Navel’ were washed, sanitized, peeled and cut. Minimal processed fruits were packed under 2 different atmospheres, passive (air) and active MAP (70% N2, 10 %O2, 20 %CO2), and stored at 10±1 °C with 85±5% RH for 12 days. Changes in package atmosphere composition, weight loss, color, texture, pH, soluble solids, sensory attributes, were evaluated after cutting and at three subsequent stages of storage (the 3 day, 6d, 9d, and the 12 day). Color parameters L* and b* s…
Preface: New challenges in anostracan research, a tribute to Graziella Mura
2017
This special volume of Hydrobiologia is dedicated to the memory of Graziella Mura, who unexpectedly passed away on 23 March 2016 when she was still carrying out her highly influential and worldrenowned research on Anostraca. She provided outstanding contributions to the current knowledge of the taxonomy and ecology of this distinctive crustacean group over the last 45 years. This volume is a tribute to her and her role in anostracan research by the community of anostracan specialists.
