In mid-2023, we performed an experiment in autonomous buses in Stockholm, Sweden, to evaluate the role that social robots might have in such settings, and their effects on passengers' feeling of safety and security, given the absence of human drivers or ...

This manuscript proposes a hybrid technique for determining the optimal positioning of phasor measurement units (PMUs) in power systems. The PMUs play a crucial role in power system control, wide-area monitoring, and protection. The proposed hybrid ...

The HVAC systems in closed buses promote high particle spread. Lagrangian particle tracking simulations were carried out to evaluate airborne COVID transmission through droplets emitted by sneezing while Eulerian simulations were performed to account for ...

Unmanned Aerial Vehicles (UAVs) are widely employed in smart city. However, the limited battery capacity is one of the UAV's most critical obstacles to monitoring mission. Recently, leveraging public buses to relay UAVs has been shown to be a promising ...

System-on-Chips (SoCs) are a key enabling technology for the Internet-of-Things (IoT), a hyper-connected world where on- and inter-chip communication is ubiquitous. SoCs usually integrate cryptographic hardware cores for confidentiality and ...

Public transport is vital to visually impaired people. In particular, they heavily rely upon the bus network that has a larger coverage area than other forms of public transportation. We observed and interviewed 14 visually impaired people, and compiled ...

Traffic congestion data can be used to provide the necessary information for public transportation optimizations like schedule improvements and fleet size estimations. This data can also be published for general use by the public. It also might be ...

In the research project 5G-VICTORI we are looking into how fifth generation mobile network technology (5G) can help improve video streaming services for train passengers. We use the principle of a local 5G-based data link between trains and 5G base ...

This article describes the vehicle electrics control system - AVELPOL (Automotive Electronics Polytechnic, acronym is structured in Russian: AVtomobil'naya Electronica POLyteha). A brief overview of existing solutions for controlling the electronics in ...

The efficiency of urban mobility is a huge concern of urban population around the world. Because of this reason, city planners spend much of their time monitoring transportations systems and designing solutions in order to improve the system's quality. ...

Power reduction is one of the primary tasks for designing modern processors, especially for high-performance throughput processors such as GPU due to their high power budget. In this paper, we propose a novel circuit-architecture co-design scheme to ...

Cities worldwide face the need to reduce the usage of private cars and the emissions. Desirability of public transportation and its services is thus of major importance. When developing novel services for public transportation, it is crucial to consider ...

Recently, we have received a growing number of reports that complain about poor and unstable internet connections at bus stops in metro Seoul. Careful analyses led us to conclude that Wi-Fi APs equipped on buses instigate the trouble. According to the ...

Japan International Cooperation Agency (JICA) led a pilot project for the introduction of a bus fare collection system through integrated circuit (IC) card in Bangladesh. The project resulted in not only improved efficiency through systemization and ...

Currently, Embedded Systems (ESs) based on Multiprocessed System-on-Chip (MPSoCs) count on resources previously available only on general purpose machines, leading to an increased design complexity, especially when dealing with communication-dependent ...

Real-time embedded systems are increasingly being built using commercial-off-the-shelf (COTS) components such as mass-produced peripherals and buses to reduce costs, time-to-market, and increase performance. Unfortunately, COTS-interconnect systems do ...

In this paper, we develop a new bus travel time prediction framework, called Historical Trajectory based Travel/Arrival Time Prediction (HTTP) for real-time prediction of travel time over future segments (and thus the arrival time at stops) of an on-...

On chip many-core systems, evolving from prior multi-processor systems, are considered as a promising solution to the performance scalability and power consumption problems. The long communication distance between the traditional multi-processors makes ...

Supporting cache coherence in current multicore processor still faces scalability and performance problems. This paper presents an optimized cache coherence design targeting at NoC-based multicore processors. It tries to achieve the best characteristics ...

Security in MPSoC is gaining an increasing attention since several years. Digital convergence is one of the numerous reasons explaining such a focus on embedded systems as much sensitive and secret data are now stored, manipulated and exchanged in these ...
