Abstract:
The 2014 IEEE 17th International Conference on Intelligent Transportation Systems (ITSC), Qingdao, China, 8-11 October 2014
As urbanization has been spreading across the world for decades, the traffic congestion problem becomes increasingly serious in most of the major cities. Among the root causes of urban traffic congestion, en route events are the main source of the sudden increase of the road traffic load, especially during peak hours. The current solutions, such as on-board navigation systems for individual vehicles, can only provide optimal routes using current traffic data without considering any traffic changes in the future. Those solutions are thus unable to provide a better alternative route quickly enough if an unexpected congestion occurs. Moreover, using the same alternative routes may lead to new bottlenecks that cannot be avoided. Thus a global traffic load balance cannot be achieved. To deal with these problems, we propose a Multi Agent System (MAS) that can ach...

Abstract:
Over the recent years, there has been an extraordinary increase in the demand for real-time multimedia and infotainment services in vehicular domain. The availability of multimedia services over mobile phones and the tremendous success of low-cost Laptops have given rise to the expectation of providing multimedia services while on the move in vehicles. However, there are significant technological challenges in establishing continuous high-rate communication between the Internet/Multimedia server and the vehicles. The main problem is that it is difficult to provide direct communication between the server and the vehicles especially when the vehicles are moving at a very high speed. This paper proposes a novel Loss-based Hybrid-architecture-oriented Adaptive Multimedia Algorithm (LHAMA) protocol, which makes use of multiple hops to maintain the connection between the vehicle and the base station/server. LHAMA enables communication between the vehicles in a multihop fashion which in-tu...

Abstract:
The 2015 IEEE Vehicular Networking Conference (VNC), Kyoto, Japan, 16-18 December 2015
Unexpected road traffic congestion caused by en-route events, such as car crashes, road works, unplanned parades etc., is a real challenge in today's urban road networks as it considerably increases the drivers' travel time and decreases travel time reliability. To face this challenge, this paper extends our previous work named Next Road Rerouting (NRR) by designing a novel vehicle rerouting strategy that can adapt itself to the sudden change of urban road traffic conditions. This is achieved through a smart calibration of the algorithmic and operational parameters of NRR without any intervention from traffic managers. Specifically, a coefficient of variation based method is used to assign weight values to three factors in the routing cost function of NRR, and the k-means algorithm is applied periodically to choose the number of NRR enabled agents needed. This adaptive-NRR (a-NRR) st...

Abstract:
The 2013 Global Information Infrastructure Symposium (GIIIS 2013), Trento, Italy, 28-31 October 2013
Due to the severe impact of road traffic congestion on both economy and environment, several vehicles routing algorithms have been proposed to optimize travelers itinerary based on real-time traffic feeds or historical data. However, their evaluation methodologies are not as compelling as their key design idea because none of them had been tested under both real transportation map and real traffic data. In this paper, we conduct a deep performance analysis and comparison of four typical vehicles routing algorithms under various scalability levels (i.e. trip length and traffic load) based on realistic transportation simulation. The ultimate goal of this work is to suggest the most suitable routing algorithm to use in different transportation scenarios, so that it can provide a valuable reference for both traffic managers and researchers when they deploy or optimize a large scale c...

Estimation of motor vehicle emissions with respect to controlling air pollution
(2012)
Achour, Hussam
Abstract:
Air pollution is becoming a very important issue for the transportation sector, particularly car emissions in urban areas, and there is much interest in evaluating the actual level of emissions across Europe and around the World. The effects of vehicle emissions can be seen from both a human perspective and an environmental perspective. The emissions from cars can have a deadly consequence on human life, as seen with the CO emission, which has been proven to be fatal to human life in a confined space. In addition, research has shown that the exposure to fuel emissions can have a carcinogenic effect on humans. This is a huge concern for people as the amount of traffic increases globally. On the other hand, energy consumption from the transport sector in many developing countries has not been dealt with the same intensity as that of developed countries. Due to the rapidly expanding mobile populations in the developing world, the issue of low carbon development and transport needs to b...

Examination of Low-cost Systems for the Determination of Kinematic Driving Cycles and Engine Operating Conditions in Dublin, Ireland
(2013)
Casey, Edward; Smith, William; Timoney, David
Abstract:
With increased numbers of vehicles on Irish roads, there is now a need to be able to scientifically assess the quantity of pollutant material to which populations are exposed. Traditionally, emissions have been determined using kinematic (vehicle speed) data but recent studies have identified that other parameters are of interest. The work in this Paper focuses on the development and testing of a purpose-built software system to extract on-board diagnostic data from a vehicle in order to derive a driving cycle and to use other engine characteristic data to better inform local pollutant and energy consumption models for Dublin. Comparisons with GPS data shows the system to be cost effective (price and computing overhead) and reliable.

Next Road Rerouting: A Multiagent System for Mitigating Unexpected Urban Traffic Congestion
(2020)

Abstract:
During peak hours in urban areas, unpredictable traffic congestion caused by en route events (e.g., vehicle crashes) increases drivers' travel time and, more seriously, decreases their travel time reliability. In this paper, an original and highly practical vehicle rerouting system, which is called Next Road Rerouting (NRR), is proposed to aid drivers in making the most appropriate next road choice to avoid unexpected congestions. In particular, this heuristic rerouting decision is made upon a cost function that takes into account the driver's destination and local traffic conditions. In addition, the newly designed multiagent system architecture of NRR allows the positive rerouting impacts on local traffic to be disseminated to a larger area through the natural traffic flow propagation within connected local areas. The simulation results based on both synthetic and realistic urban scenarios demonstrate that, compared with the existing solutions, NRR can achieve a lower av...

Notions of a Learning Society and Learning Partnership Vehicles: the Island's Project, a Case Study
(2010)
Murphy, Fergus
Abstract:
This case study focuses on the Partnership Vehicle that was jointly developed by the School of Art, Design and Printing at the DIT, and the Sherkin Island Development Society in the period 1998 to 2004, in order to construct and deliver a pilot Fine Art programme on Sherkin Island in West Cork. The pilot programme was delivered on Sherkin from 2000 to 2003, and subsequently, based on the pilot, the School of Art, Design and Printing developed a prototype Fine Art degree aimed at isolated communities. This course is currently being delivered on Sherkin. A third level-community partnership seems an ideal mechanism for furthering academic, local-community and indeed, society’s educational aims and goals. However, in order to function at a meaningful level the partners need to display a high degree of flexibility and understanding of each other’s needs (and limitations) in order to move toward their goals. In order to describe and understand this process and the journey undertaken by th...

Abstract:
The circumstances of globalization and ever-stricter environmental legislation over the past decade have led enterprises to work together to transform products into extended products, and to manage these throughout their lifecycle. Innovative radio frequency identification (RFID) technology can be introduced as an enabler or product lifecycle management (PLM) business, by enhancing the traceability of the product throughout its value chain via automatic identification, enabling the collection of product usage information during its middle-of-life (MOL) phase, and facilitating the integration of product lifecycle information and knowledge across the value chain, thus closing the product's information loop from beginning-of-life (BOL), through MOL, to end-of-life (EOL) and back again. This paper will introduce a framework for product lifecycle information management with the support of RFID technology. A case study of how the framework supports the decision-making involved in the...

Abstract:
IEVC 2014: IEEE International Electric Vehicle Conference 2014, Florence, Italy, 17-19 December 2014
With the introduction of new technologies like electric vehicles and smart grids the operation and planning of power systems are subject to major changes. These technologies can bring various flexibilities to different entities involved in decision making. This paper proposes a robust optimization based method to optimal charging/discharging of electric vehicles considering the electricity price uncertainties. The objective function is defined as the total operating costs of energy procurement in distribution networks which is tried to be minimized while considering the technical constraints of the problem.

Abstract:
New therapeutic approaches aim to eradicate tumours by expression of tumouricidal proteins in the tumour stroma. One such anti-neoplastic protein is tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) because it induces apoptosis in cancerous cells, but not in non-transformed cells. Stem cells can migrate to, survive and proliferate in tumours. We examined the suitability of bone marrow-derived adult mesenchymal stem cells (bmMSC), foetal-MSC and umbilical cord matrix stem cells (Wharton's Jelly MSCs) as TRAIL-delivery vehicles. Although all MSC types expressed DR4 and/or DR5, none of them were sensitive to TRAIL-induced apoptosis. Selective activation of DR4 or DR5 with agonistic antibodies or DR5-selective TRAIL-mutant (D269H/E195R) revealed that the TRAIL receptors are inactive in MSCs. In fMSC DR5 was not fully inactivated, its activity however was minimal in comparison to the colon carcinoma cell, Colo205. The intracellular components of the TRAIL-apoptotic pa...
