Halton, Henrik Hansen, Lee Bramald and Fraser Campbell will be participating in the ISAVFT (International Symposium on Aerodynamics, Ventilation & Fire in Tunnels) conference in Copenhagen, 28th?-30th?October 2024. ISAVFT is a technical conference focused on tunnel engineering with a particular focus on aerodynamics, ventilation and fire safety. The participants include world-leading experts amongst engineers, researchers and policymakers sharing the latest advancements. The event includes different presentations about optimizing airflow, maintaining air quality, controlling temperature and improving fire safety systems in tunnels. ISAVFT aims to transform transportation infrastructure to meet future needs and demands by using information and data-based insights. The key elements are to improve connectivity, reduce congestion and to improve the overall user experience of transport. We have front row seats to participate in perceptive discussions and collaborate together with other experts, while also sharing our knowledge. Let’s be a part of big discussions and positive changes! #WellbeinbyHalton #GreenTransition #Sustainability #EnergyEfficiency #Innovation #HVAC #ChangeForTheBetter #Innovations #Symposium #SharingKnowledge #Collaboration #PositiveChanges

This paper analyzes the performance of an indoor #visible #light #communication (#VLC) system with dynamic #human #blockages. Specifically, the authors use the #random #waypoint (#RWP) #model to characterize the movement of the blockages. The system performance is analyzed for a #4-#LED configuration, where the blockages can pause during the movement for a specific pause time. Further, they developed a model to calculate the #blockage #probability in a #typical #indoor #space, which is consequently used to calculate the power at the VLC receiver. Additionally, the analysis is extended for multiple blockage scenarios with different pause times. The #second-#order #statistics such as #level #crossing #rate (#LCR) and #average #fade #duration (#AFD) have been examined to demonstrate the impact of both pause time and the number of blockages on this dynamic time-varying indoor VLC channel.----Tathagat Pal, Dr. ANAND SINGH, Vivek Ashok Bohara, Anand Srivastava More details can be found at this link: https://lnkd.in/gStu3Dt3

This paper aims to optimize multiple #reconfigurable #intelligent #surfaces (#RISs) to control the signal propagation environment for maximizing the signal-to-interference-plus-noise ratio (SINR) in a #multiuser #MIMO system. The authors examine two approaches for managing interference and determining the optimal phase shifts for the RIS elements. They also evaluate the asymptotic expressions for the optimal phase shifts and maximum SINRs as the number of base station antennas becomes very large. ---- Somayeh Aghashahi More details can be found at this link: https://lnkd.in/edgnRK4Z

Since the recent release of our RTK Postcard and SparkFun Quadband GNSS RTK Breakout, we've been getting a lot of questions about the underlying technology behind Quectel's LG290P module, Quadband reception. What is quadband and how is it different from triband or even dualband? Is it just a marketing gimmick? We answer these questions and more in our newest blog! Read it now - https://bit.ly/3ZX0wTz

Is 5G/6G mmWave the high-datarate option for indoor dense spaces in aircraft, trains, ...? The dependence on frame material and the deviation from 3GPP's indoor-office model is studied in this recent article co-authored with Ozan Alp Topal , Zhenyu Li , Mustafa ?zger , Emil Bj?rnson , and Cicek Cavdar. Special thanks to Ozan for the work on this article! https://lnkd.in/d5V_GbaN

This work evaluates the effectiveness of a novel #one-#way #time of #flight #based #passive #ultra-#wideband (#UWB) inertial navigation solution for indoor positioning of a #mobile #platform and formulates a design criterion for choosing between #passive #systems through #noise #analysis. The proposed #tightly #coupled #time #of #arrival (#TC-#TOA) approach achieves passive synchronization by #keeping #track of the #local #clock and its #derivatives as states. Using these states and position estimate, the #reception #timestamps of the network messages are predicted. The errors in these #predicted #timestamps are then used to update both #clock #states and the position states through accurate modeling of coupled interactions. The design results in a #tightly #coupled #estimator #formulation achieved using an error state #Kalman #filter with #right #quaternion #error #parameterization.----Nushen Senevirathna, Oscar De Silva, @George K.I.

I’m happy to share with you the first results of one of our ongoing collaborative projects focusing on the development of a new method to study the acoustic factors driving the short-term annoyance experienced by neighbours of high-speed train lines. Our objective is to be able to better explain annoyance caused by high-speed trains noise, to improve current indicators by considering new event-related aspects who are not yet fully understood and finally to improve the quality of life of high-speed train lines neighbours. Ma?l, Guillaume, keep up the good work for fewer cars, a diminished annoyance and, obviously, more trains! https://lnkd.in/em9frUGa
