Low and infrequent demand in rural areas poses a problem for public transport providers to run cost-effective services and individual car use is usually the main means of transportation. We investigate how microtransit services can be integrated with existing public transport solutions (bus, train) as a flexible shared mobility alternative in rural areas and how to make them attractive alternatives to individual car use. We combine large neighborhood search with agent-based modeling and simulation to validate generated schedules for a microtransit service in terms of vulnerability to tardiness in passenger behavior or service provision. This includes the study of how disturbances, such as delays in service provision or late arrivals of passengers affect the stability of a transport schedule concerning a reliable timely delivery to transfer stops. We explore how simulation can be utilized as a means to fine-tune provider policies, e.g., how long vehicles may wait for late passengers before they depart.

New vehicular applications demand more computing power and real-time processing. As modern vehicles are equipped with computationally powerful but often redundant and under-utilized onboard units for autonomous driving, a network of connected vehicles can form a vehicular cloud (VC) that can provide computing services among themselves or to other devices. In this paper, we evaluate the computing performance of a VC on a highway in congested traffic. We assume that the vehicles join and leave VC at random times. Thus, the number of vehicles in the VC will be time-varying. The residency times of the vehicles in the VC will be correlated because of traffic congestion. To enable the realization of VC in the future, we need to know its computing performance that considers its dynamic nature and concurrent execution of the tasks. In this work, we determine the completion time of a job with multiple tasks with random execution times. More specifically, we derive the probability density function of the job completion time as a function of the system parameters. We provide numerical results to demonstrate the utilization of the analysis and simulation results to confirm the correctness of the analysis.

As the demand for clean energy sources increases on a large global scale, electric vehicles (EVs) are currently witnessing a huge demand to replace gas-powered vehicles. A crucial part in EVs is the battery management system, which utilizes DC-DC converters as essential parts. For this purpose, non-inverting DC-DC converters are the most desirable type. Moreover, these converters need to operate in continuous conduction mode (CCM) to minimize harmonic distortion and keep the load always fed with current. In this paper, we propose a novel design of a DC/DC quadratic non-inverting buck boost converter that has two switches and combines three different converters. A simulation model was constructed to investigate the converter performance for duty cycles from 30% to 80% in the CCM. The simulation results obtained not only revealed good performance in the desired duty cycle range but also confirmed the operation in CCM.

Classic blockchain protocol design is centered around a computationally-intense cryptographic scheme, such as Bitcoin's Proof-of-Work (PoW). Network scalability and efficiency are stifled with the computational resources necessary to approve new transactions, thus rendering PoW unsuitable with limited devices like Internet of Things (IoT). As a first step towards alleviating this, a novel lightweight Generative Adversarial Network (GAN) called Vector GAN (VecGAN) is introduced wherein its weights are tuned through a direct error-driven learning approach with a Bayesian estimator for the selection of random noise matrices, called Bayesian Feedback Alignment (BFA), to augment data for improved fraud prediction. The augmented data is subsequently processed by a classifier for prediction. This combination of VecGAN with a classifier is treated as a novel method of blockchain ledger decision-making to approve ground-truth data. By using the two-step process, prediction accuracy using a classifier was improved up to 8% for real-world datasets. Resource consumption comparison to existing IoT blockchain protocols in a realistic simulation environment is also provided, where lightweight approaches for VecGAN in training and noise modeling reduce computation compared to other techniques.
In recent years, many Chinese construction enterprises began to use building information modeling technology (hereinafter referred to as BIM). This is a global trend designed to maximize automation and speed up the de...

This research study compares the accuracy of different techniques based on deep learning (DL) for predicting turbulent flows. Different types of Generative Adversarial Networks (GANs) are examined in terms of their applicability to the study and simulation of turbulence. Next, we select Wasserstein Gans (WGANs) to produce localized disturbances. Network features including the learning rate and loss function are examined as they pertain to the performance of the WGANs during training on turbulent data gleaned from high-resolution Direct Numerical simulations (DNS). DNS input data and the generated turbulent structures are proven to agree qualitatively well. The projected turbulent fields are evaluated quantitatively and statistically.

Parking in large metropolitan areas is often a time-consuming task with further implications for traffic patterns that affect urban landscaping. Reducing the premium space needed for parking has led to the development of automated mechanical parking systems. Compared to regular garages having one or two rows of vehicles on each island, automated garages can have multiple rows of vehicles stacked together to support higher parking demands. Although this multi-row layout reduces parking space, it makes parking and retrieval more complicated. In this work, we propose an automated garage design that supports nearly 100% parking density. modeling the problem of parking and retrieving multiple vehicles as a special class of multi-robot path planning problem, we propose associated algorithms for handling all common operations of the automated garage, including (1) optimal algorithm and near-optimal methods that find feasible and efficient solutions for simultaneous parking/retrieval and (2) a novel shuffling mechanism to rearrange vehicles to facilitate scheduled retrieval at rush hours. We conduct thorough simulation studies showing the proposed methods are promising for large and high-density real-world parking applications.

Massive process measurement message brings great computational complexity and modeling complexity to the traditional breakdown diagnosis algorithm, and the traditional diagnosis algorithm has the disadvantage that it is difficult to make online estimation by using high-order quantities. Modern industrial systems have been developing towards largescale and complexity, which makes the breakdown diagnosis means for industrial systems encounter a series of technical questions. In view of the powerful data representation learning and analysis ability of deep learning technique, breakdown diagnosis based on deep learning has attracted wide attention from industrial and academic circles, and has made intelligent process control more automatic and resultful. The means adopted in this paper is deep learning, which is carried out alternately by convolution and sub-sampling. At last, the algorithm close to the output layer adopts the common multilayer neural network. As a breakthrough in the domain of latter-day artificial intelligence, deep learning can voluntarily learn valuable traits from the original trait set or even the original data. The research in this paper shows that the algorithm in this paper is resultful in breakdown prediction, and it is suitable to be widely applied in practical applications.

One of the blooming technologies of AI is the metaverse, The Metaverse is a virtual environment in which users may interact with virtual things and with one another. The Metaverse can be utilized in Military GeoIntelligent systems to build a virtual training environment, allowing Defence personnel to practice in realistic circumstances without the need for costly physical resources. The military personnel can practice in a virtual training environment using the Metaverse that can be created with realistic scenarios. This can aid in enhancing their abilities, judgment, and quickness of response. For instance, pilots can practice flying in various weather conditions, soldiers can hone their tactical skills, and cyber security officials can practice responding to cyberattacks. In this paper, we have focused on AI-based technologies combined with the geo intelligence and metaverse which can jointly help in defence to model and analyse complex geographic situations, allowing defence specialists to explore numerous situations and evaluate the effectiveness of different strategies before deploying resources, with the goal of improving situational awareness, response times, and decision-making capabilities across all security-related agencies. The satellite images obtained from the geo satellites give a brief description of a variety of different types of maps and visualizations, including topographic maps, vegetation maps, and thermal maps. These types of satellite imagery include infrared images, the locations of water bodies, planes, plateaus and a number of other surface structures of earth. The imagery helps in identifying the loopholes of spotting the enemy hiding locations and the risky regions of exposure of the native soldiers. The AI model can identify such locations and predict the possible threat locations. When this kind of model is deployed in the metaverse, it can help the soldiers in being trained for war zone like situations. The predictive outcome can hand
