Mobile cloud gaming (MCG) lets users play cloud games (CG) on mobile devices anywhere via mobile networks. However, the stochastic nature of network quality of service (QoS) can result in varying user quality of experience (QoE). Understanding, modeling, and predicting the impact of mobile networks' QoS on users' QoE is crucial. This helps stakeholders optimize networks, and game developers efficiently create cloud-hosted games provisioned over mobile networks. This paper investigates the impact of QoS on users' QoE and proposes, develops and validates novel models for predicting QoE for MCG in mobile networks using realistic subjective tests. In particular, we propose and develop three QoE models using multiple, polynomial, and non-linear regression. Our results validate that multiple regression (with R 2 =0.79, RMSE=0.45) can model complex relationships between QoS factors that impact QoE. Multiple polynomial regression achieved the overall fit with (R 2 =0.94, RMSE=0.24). Lastly, the non-linear model achieved a good RMSE of 0.24. To select the best model out of the three, we applied the F-test and determined that polynomial regression had the best statistical fit.

Plug-in Electric Vehicles (PEVs) are rapidly expanding in the transportation sector and are an emerging component of the power grid uncertain load. The high level PEV penetration will impose additional demand and will have a negative impact on the power grid. A complete load profile model is required to ensure a realistic and implementable plan related to PEVs and their impact on the power grid. In this paper, a methodology is proposed to estimate the PEV charging load and available storage profile model using the travel patterns derived from the national household travel survey (NHTS). The most recent published national household travel survey (2017 NHTS) is used to approximate the travel patterns of PEVs. The charging profile model proposed in this section aims to be utilized for reliability analysis purposes.

Due to the benefits of direct inclusion of weather measurements in the power flow studies compared to using cumulative utility capacity factors, we introduce a methodology for the estimation of renewable energy output from detailed ERA5 data based on the U.S. Energy Information Administration generator data and power models and then validate the calculated results of each generator, using publicly available resources. Validation is performed by comparing our estimations against publicly available data for the largest renewable generators in the U.S. The analysis reveals strong correlations with reference capacity factors, underscoring the effectiveness of our approach. This validation not only supports the proposed strategy but also highlights its potential for improving renewable energy models.

Residents of “smart cities” have access to cuttingedge services designed to enhance their daily lives. But it has been noted that there would be particular challenges with the gathering, storing, processing, and analyzing of diverse data that citizens typically bear. Threats to sensor data, products and services, and applications for smart cities may have been introduced by Industry 4.0 factors such as the expansion of the World Wide Web of Things, the use of cloud social media, as well as other similar developments. Data security issues arise as a result of these vulnerabilities. To address the issue of data vulnerability, we provide a decentralized data management platform for safe and intelligent transportation that integrates blockchain technology with the World of Things within an environmentally friendly smart city setting. In order to guarantee efficiency and adaptability, a smart mobility system necessitates the development of an integrated transportation network. Following an overview of relevant background material, this paper presents a data architecture based on Hyperledger Fabric that facilitates a trustworthy, secure smart transportation system.

We report advances in packaging and testing for existing Complementary Metal Oxide Semiconductor (CMOS) chips that extend their longevity and reusability, thus increasing their effectiveness in monitoring cell viability and facilitating concurrent visual inspection. We created several Printed Circuit Board (PCB) designs aimed at mitigating packaging failures while facilitating data collection using a microcontroller ensuring the creation of a reliable and replaceable cell viability measurement device. Using 3D Modeling software and programming Field Programmable Gate Arrays (FPGA), we developed a rapidly interchangeable test platform and established a data readout system. These advancements notably enhance research efficiency and data quality by minimizing downtime and improving the correlation of capacitance measurements with direct visual observations of cell behavior.

The lack of extensive data on severe geomagnetic storms has necessitated the need to generate synthetic time-series electric field, particularly to assess and predict the im-pact of such extreme storms on the resilience of the electric power grid. Due to geomagnetic disturbances, geomagnetically induced currents (GIC) can lead to half-cycle saturation of the transformers, placing the equipment at the potential risk of experiencing increased hotspot heating. This paper describes a methodology for generating extreme synthetic geomagnetic storms through an iterative process of temporally and spatially varying the fragments of the NERC benchmark event by scaling the time duration, magnitude, and direction of the storm. In addition, the results of the thermal sensitivity of the transformers to the assumed quasi-de electric fields simulated on a large-scale synthetic electric grid are presented. Further engineering assessments may utilize the computed extreme GIC scenarios.

The United Arab Emirates has a large and sophisticated street lighting infrastructure; therefore, the photometric performance of the street lighting systems must be prioritized. Locating the malfunctions in a large street lighting infrastructure can be time-consuming and arduous. In this paper, a low-cost street lighting performance monitoring system is designed, implemented, and tested. The proposed system comprises three main components: an illuminance sensor, a spectrometer, and a GNSS receiver. These components build a light and robust system to mount on vehicles' rooftops. Additionally, a comprehensive data analysis and inference engine is developed to determine the photometric performance of the lighting poles by identifying the number and the position of the defective luminaires, under-performing luminaires, poles obstructed by vegetation, and lighting poles that suffer from a complete power outage due to electrical faults in lighting control cabinets. Lastly, the field survey results are demonstrated in reports and interactive online visualization using Google Maps, in which the obtained information can be converted into performance metrics and indexes overlayed on urban maps.
