Abstract: Faced with today's critical issues in the management and maintenance of infrastructures - due to factors such as age, structural complexity and the limitations of traditional inspections - this study systematically addresses the entire set of maintenance issues, proposing the integrated use of innovative digital technologies as an answer. The research presents an advanced methodology based on the synergy between Building Information Modeling (BIM), Internet of Things (IoT) and Machine Learning (ML), with the aim of supporting the predictive and dynamic management of infrastructures through the creation of Digital Twins. In this paper, this methodology is applied to two case studies of bridges in Italy, which are currently being monitored. The application focuses on the initial stages of the process: digital modelling of the works (with the creation of BIM models containing static data), installation of sensors for the collection of dynamic data in real time, and subsequent integration of this information for the generation of a functional Digital Twin. This unified model allows not only the management of warning systems based on predefined thresholds, but also the elaboration of in-depth structural diagnoses to support the planning of maintenance interventions. The proposed methodology also represents a strategic step towards the evolution of advanced predictive models, favouring a more proactive, efficient and sustainable approach to maintenance.

Abstract: The Internet of Things is one of the most revolutionary technologies since the past few years that has brought to humans unprecedented levels of connectivity, providing functionality and appliances in different industries across the world. However, as with everything that has connection to the internet, IoT is also not exempted from security attacks and risks. This technology faces various privacy and cybersecurity vulnerabilities, and if these vulnerabilities are taken advantage of by attackers it can bring severe consequences and threats to homes and industries. Conventional security methods seem to be not achievable for IoT devices, that is why this work presents an introduction on what is an IoT device, what is the magnitude of the risk in security they are exposed. The three pillars on security of IoT devices are discussed to understand the importance and how the security methods work to maintain all the three pillars. After introducing the topic, different mitigation solutions by multiple authors are discussed in this work to help us have a clear view on the landscape of the risk and vulnerabilities on IoT devices that can affect the usage and confidence on them.

Abstract: Nowadays Wireless Sensor Networks (WSNs) are a very promising device to monitor environmental events, which are used in many application areas such as agriculture, environmental monitoring, air-water pollution, greenhouse, health monitoring, structural monitoring etc. Also, WSN needs effective and efficient way of collecting data from the area over which it is deployed, since the network consists of battery-operated nodes with limited energy. Improving the lifetime of WSN for continuous monitoring applications are very essential because of simple deployment, low installation cost, lack of cabling, and high mobility. The better energy conservation and reliable data transmission would be achieved in WSN by adopting efficient routing protocols for better and reliable communication. Also, security in data transmission in WSN is still a challenging task. Hence, a better way of encryption has to be computed to promote a reliable transmission between the nodes. In this paper discusses about different routing protocols which support energy efficiency and security techniques in WSN.

Abstract: In order to monitor the current state of buildings and structures effectively the author proposes development and maintenance of constantly updated electronic databases of buildings and structures to manage the safety of buildings and structures operation, which provides an opportunity to receive information on technical condition of the facility in real time mode, which allows increasing the effectiveness of buildings’ owners, operating organisations, state supervisory and control bodies for safe operation as well as simulates emergency situations and predicts the behaviour of structures with regard to their repair and reconstruction.

Abstract: One of the most important urban areas is street s and intersections that play an important role in shaping the overall identity of a city. The city is defined by the presence of the humans at night and nightlife plus visual sense plays the most important role in the perception of urban space. In addition, most of the things that are received by the sense of sight are with the help of light. Therefore, light and lighting in urban spaces as a non-physical element will have a huge impact on the quality of urban space. The main question in this study is the effects of lighting on the pedestrians’ understanding of the sense of security in Valiasr Street .In this regard, two variables of light color and light intensity are evaluated and considered based on eight hypotheses. To test these hypotheses, the main variables were first investigated and scrutinized. Then, according to the survey conducted, indicators related to the variables were determined and the items were designed. The main data collection tool is the questionnaire and among the pedestrians of Valiasr Street in Tehran that were selected as statistical population, 228 persons were randomly questioned. Due to the discrete nature of variables, a nonparametric function was used for their analysis. Calculation method using Kendall’s correlation analysis was analyzed using SPSS software. The findings show that that the satisfaction rate of light intensity is low, but their satisfaction with the lighting, light color, sense of security, and the ability to recognize faces is assessed averagely. Regarding the light color, people preferred white color to yellow one. The findings in this study suggest that using the white light instead of yellow and increase of light intensity increase the sense of security in pedestrians.

Abstract: Autonomous cars recognize the surroundings through multiple sensors and make decisions to control the car in order to arrive at destination without driver's interventions. In such environment, if sensor data forgery occurs, it could lead to a big (critical) accident that could threaten the life of the driver. In the paper, a research on a way to get accurate driving information through sensor fusion algorithm that has resilience against data forgery and modulation will be discussed.
