Modeling Efficient and Effective Communications in VANET through Population Protocols

2021

Vehicular Ad-hoc NETworks (VANETs) enable a countless set of next-generation applications thanks to the technological progress of the last decades. These applications rely on the assumption that a simple network of vehicles can be extended with more complex and powerful network infrastructure, in which several Road Side Units (RSUs) are employed to achieve application-specific goals. However, this assumption is not always satisfied as in many real-world scenarios it is unfeasible to have a conspicuous deployment of RSUs, due to both economic and environmental constraints. With the aim to overcome this limitation, in this paper we investigate how the only Vehicle-to-Vehicle (V2V) communicati…

Chimney endografting for pararenal aortic pathologies using transfemoral access and the lift technique

2013

Purpose: To present a technique for transfemoral implantation of parallel grafts into the renal arteries in patients with anatomy or morphology that blocks standard antegrade chimney graft delivery. Technique: In a totally percutaneous approach, a 5-F pigtail angiographic catheter is passed into the aorta above the renal arteries via a 0.035-inch hydrophilic guidewire, followed by an 8-F sheath. The target vessel is cannulated with the hydrophilic wire followed by a 5-F reverse curve catheter; the wire is changed for a Rosen wire. The main stent-graft body is delivered and parked at the level of the aortic bifurcation. The Viabahn chimney endograft is advanced ~1 to 2 cm into the target ren…

Local Leadership and Its Limits in the Deployment of Sustainable Mobility Policies

2020

The indisputable need for new urban mobility policies, which has already been recognised in numerous international, European and national legal instruments, undoubtedly requires a local role in the redefinition of these policies. This action must be carried out in a regulatory context that does not always provide local authorities with all the legal instruments to do so. In this contribution, the primary measures being used to achieve greater sustainability of urban mobility are outlined, as well as a description of the effective room for manoeuvre local authorities normally have, analysing the current limitations they face for a more ambitious deployment and possible models of alternative …

Development Platforms as a Niche for Software Companies in Open Source Software

2006

As long as information systems do not become overly large and while they address a well-known domain, they can be controlled by engineering staff. Nevertheless, when dealing with large-scale, complex, or innovative information systems, it can be difficult to separate design issues and to formulate a meaningful information system proposal. In such a context, platforms for software engineering appear to be a promising approach. In this paper, we propose to view development platforms as a major opportunity for Open Source Software and Open Formats.

Scenarios on Adoption of Open Source Software in the Communications Software Industry

2011

We examine the trends and developments affecting the adoption of open source software in the communications software industry. Based on expert interviews and scenario analysis, four alternative and possibly co-existing scenarios are derived. The analysis suggests that communication service providers will mostly deploy open source software in infrastructure software. Alternative developments include use of open source software in launching new services and in cloud computing. The present study is relevant particularly for technology managers considering open source strategies.

Diffusion of software technology innovations in the global context

2003

This study examines how software businesses are acquiring new software technology innovations (STIs) in rapidly changing globalized business environment characterized by rapidly shortening software technology life cycles, changing customer demands, and intense competition. It was executed through both theoretical and empirical investigations and analyses. It describes one case company as an example of the diffusion of STI and develops a framework for the diffusion of software technology innovation. The research findings are useful for both further research and industrial settings.

Challenges and Opportunities for Renewable-Based Microgrids Integration in Vietnam

2020

Vietnam is among the South-Asian regions the one that better supplies remote areas. However, many islands and remote areas are still not connected to the main grid and this fact jeopardizes their development, while forcing people to move to urban areas. With a high potential from renewable energy sources and a lot of islands, Vietnam has thus many favorable environmental features for developing the microgrids technology. In this chapter, a detailed analysis about opportunities and challenges for widespread deployment of microgrids technology in Vietnam is considered. Such analysis is based on the assessments of the potential from renewable energy sources in the country and of the national p…

A metrics suite for evaluating agent-oriented architectures

2010

The Multi-agent Systems (MASs) paradigm continues to consolidate itself as a new branch of software engineering. Traditional software engineering strongly recommends to apply metrics in software developments. However, several research groups of experts in agent-oriented software engineering agree that classical software metrics and object-oriented metrics cannot directly measure the quality of MAS architectures. For this reason, this work proposes a suite of metrics to measure certain quality attributes of MAS architectures, considering agents and their organization. Most of these metrics are inspired by object-oriented metrics but they are adapted to agent-oriented concepts. Proposed metri…
