Examining the effect of adverse weather on road transportation using weather and traffic sensors.
2018
Adverse weather related to reduced visibility caused by fog and rain can seriously affect the mobility and safety of drivers. It is meaningful to develop effective intelligent transportation system (ITS) strategies to mitigate the negative effects of these different types of adverse weather related to reduced visibility by investigating the effect of rain and fog on traffic parameters. A number of previous researches focused on analyzing the effect of adverse weather related to reduced visibility by using simulated traffic and weather data. There are few researchers that addressed the impact of adverse weather instances using real-time data. Moreover, this paper conducts comprehensive inves…
Blockchain based Device identification and authentication in a Smart Grid
2020
The power grid is a critical infrastructure of a country that needs protection and security. According to the report of the International Energy Agency, the electricity demand is constantly increasing the world over. Countries are moving towards green energy and efforts are being made to integrate these green energy into the main grid. Smart Grid will improve the reliability and efficiency of the grid by managing the energy demand. Cyber-attacks and cyber terrorism is also increasingly targeting the electrical grid. Intruders may try to gain access to the grid by exploiting the vulnerability of the grid. IEDs/devices are the endpoints of the network and they are the weakest link in the enti…
Simulation-Based Analysis of "What-If" Scenarios with Connected and Automated Vehicles Navigating Roundabouts.
2022
Despite the potential of connected and automated vehicles (CAVs), there are still many open questions on how road capacity can be influenced and what methods can be used to assess its expected benefits in the progressive transition towards fully cooperative driving. This paper contributes to a better understanding of the benefits of CAV technologies by investigating mobility-related issues of automated vehicles operating with a cooperative adaptive cruise control system on roundabout efficiency using microscopic traffic simulation. The availability of the adjustment factors for CAVs provided by the 2022 Highway Capacity Manual allowed to adjust the entry capacity equations to reflect the pr…
VIRTUAL REALITY AND BIM FOR INFRASTRUCTURES
2023
Abstract. Building Information Modelling (BIM) has been widely adopted in the construction industry as a means of improving project efficiency, reducing errors, and facilitating collaboration among stakeholders. However, its potential for the infrastructure sector has not been fully explored. Infrastructure projects, such as roads, bridges, tunnels, and airports, are often complex and require the integration of multiple systems and disciplines. BIM has the potential to provide a digital representation of the infrastructure project, allowing for improved design, construction, and maintenance. This paper aims to explore the potential benefits of BIM in the infrastructure sector, examine the c…
ISIM - INFRASTRUCTURES & STRUCTURES INFORMATION MODELING: A NEW CONCEPT OF BIM FOR INFRASTRUCTURES
2023
The application of Building Information Modeling (BIM) in infrastructure and structural projects, known as Integrated Structural and Infrastructure Modeling (ISIM), has gained attention in recent years due to its potential to revolutionize the construction industry. By providing a digital representation of the built environment, BIM allows for improved collaboration and communication between project stakeholders, leading to enhanced project outcomes. The ISIM approach is centered on the creation of a digital twin, a three-dimensional model of the infrastructure or structure, which serves as a virtual replica of the physical asset. This digital twin provides a platform for analysis, decision…
Foreign direct investment attraction in the Baltic States
2014
This paper considers the importance of macroeconomic factors as well as investment climate for foreign direct invest ment attraction in the Baltic states. It reviews some of the indicators for measuring the investment climate and their usefulness as indicators of strength of FDI attraction and uses the results of econometric analysis to consider relative importance of various macroeconomic factors. The results suggest that perceptions of corruption and fiscal policy are some of the more important drivers of FDI attraction. The paper also considers several measures that could improve foreign direct investment attraction in the Baltic States such as expanding the protection of property right…
Iekšējā tūrisma attīstība Kaļiņingradas reģionā
2015
Kaļiņingradas apgabals ir unikāla Krievijas Federācijas teritorija ar īpašu ģeogrāfisko atrašanās vietu, kurai ir liels dabas un vēsturiskais potenciāls tūrisma attīstībai. Maģistra darba mērķis ir novērtēt situāciju tūrisma jomā šajā reģionā, tā turpmākas attīstības priekšnoteikumus, kā arī sagatavot priekšlikumus, lai sekmētu iekšzemes un starpvalstu tūrisma attīstību.
Verso una dimensione narrativa delle mappe
2021
Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…
Civic resielience : botanical gardens in North America, birth, development, and enviromental awarness
2023
The chapter explores from a historical perspective the birth of botanical gardens in North America, considered a significant part of the ecological network system and of the green and blue 'infrastructure'. This important system opposes geographical risk, which must be organically dealt with in programmes, plans and strategies that protect the landscape, prevent risks, and strengthen short-, medium- and long-term actions, also involving local Communities, integrating the vision to the different scales of intervention and projects. The Botanical Garden, seen here as an 'Open Work', has an important role not only because it preserves botanical specimens that come from all over the world, but …
Multiagent System for Detecting and Solving Design-Time Conflicts in Civil Infrastructure
2012
One typical source of problems in the Civil Infrastructure domain is the distributed and collaborative nature of the projects in which different profiles of engineers contribute with designs devoted to the interest of their field of expertise. Thus, situations in which there are different conflicts of interests are quite common. A conflict refers to a situation in which the actions of an engineer collide with the interests of other engineers. In this paper, we present a multi-agent system that, thanks to the use of ontologies and rules on those ontologies, is able to detect profilespecific conflict situations and solve them according to the preferences of the parties involved in the conflic…
