This paper presents a novel approach to estimate and compensate for the misalignment between the Inertial Measurement Unit (IMU) and Doppler Velocity Log (DVL) sensors. Estimating the location and attitude of an ROV usually combines the attitude by IMU and the velocity by the DVL provided in the sensor coordinate system. The attitude is regarded as the attitude of the ROV and the velocity in the sensor coordinate frame is converted to the velocity in the inertial coordinate frame. Misalignment in the DVL and IMU causes errors in the converted velocity and results in the degradation of the navigation performance. The proposed method represents the misalignment using unit quaternion. Especially, the method utilizes the Lie theory to deal with the operations on unit quaternions which constitute a Lie group, called the 3-sphere group. Simulation and testing of the method in a marine environment validate its effectiveness and practical applicability. © 2023 ICROS.

The process for producing intelligence is traditionally represented by a series of steps forming a cycle. Collection is one of these stages and is characterized by the application of a set of disciplines to obtain information that will be analyzed for the production of an intelligence product. These disciplines are characterized according to the type of source, its methods and techniques. Open-Source Intelligence (OSINT) is the collection discipline focused on publicly available information. Open-source collection methods are usually represented by working diagrams that draw a flow according to the type of information. This paper makes a comparative study of the intelligence cycles of some relevant actors in the international OSINT scene, locates open-source collection in the intelligence cycle, and presents a workflow that combines this cycle with the techniques that form a method for OSINT. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

We analyze wholesale datasets from Indonesian Automobile Industry Data for electric cars in Indonesia using statistical analysis to predict the electric cars used in the future. We apply a linear regression approach that adjusts the regression model according to wholesale electric cars between 2020 and 2022, as well as a statistical correlation test and the Wilcoxon test to support the regression result. We find a strong positive relationship for electric cars bought in the future, with a not significantly different population median of the total number of wholesale electric cars. It might be 210 cars estimated per year. Among the regression model, it is more effective for policymakers, as well as car industries. We estimate that there are various reasons and conditions for Indonesian people regarding buying electric cars inside conventional ones. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Co-presence is the index that indicates the degree to which the observer believes he/she is not alone and secluded. The representation of avatars in virtual environments (VE) having an effect on co-presence was reported. However, these reports are only limited to visual interaction. This paper aims to clarify the influence of the avatar representation on cooperative haptic interaction. Haptic interaction in the VE is essential for teleoperation. A cooperative task with multilateral control was conducted, and the haptic interaction was analyzed by conducting a survey. In the experiment, the avatar representation was changed by three patterns of the avatar representation as follows;all of subjects' avatars are displayed, only the subject's avatar is displayed, and all of subjects' avatar is not displayed. The experimental results showed that the avatar representation did not affect the haptic interaction. On the other hand, the subject's impression was changed by the avatar representation. Therefore, it was concluded that the avatars are not always necessary in a cooperative task. © 2022 IEEE.

In recent years, 3DCG-related industries have grown rapidly and the demand for 3DCG content has increased. However, 3DCG production requires special skills and a lot of time. In particular, the creation of background data requires a lot of human resources at the production site because the data is huge and complex. Therefore, we propose an automatic creation system that generates 3D background data for 3DCG production. The proposed system consists of three functions: 3D model generation, generation parameter optimization, and fitness evaluation. The user inputs a landscape photograph as idea information into the system, and the system optimizes the generation parameters so that the 3D object shape approximates the input image. To evaluate the accuracy of the system's performance, we observe the optimization process and the 3D object output when a previously generated fractal image or landscape photos are input. Experimental results show that the system accurately optimizes the generation parameters and generates 3D objects that are almost identical to the shape of the fractal image. In addition, the parameters were also optimized with a certain degree of accuracy for landscape photographs for which no specific solution had been determined. © 2023 IEEE.

Recently, energy storage devices (ESDs) have been introduced to railway vehicles to operate even in an emergency case, such as a power outage. However, there have been no proposals for simultaneous design methods of power capacity and energy capacity of onboard ESD for emergency operation. In this paper, a model for the calculation of power and energy capacity of onboard ESD, which are utilized in an emergency case, is proposed. Furthermore, we propose a method to design the power and energy capacity of onboard ESD by considering the required power for traction and an auxiliary power supply system. © 2023 The Institute of electrical Engineers of Japan.

In this study, we propose a method for enabling humans to initialize a neural network before training. This is a novel way of involving humans in neural network training. So far, neural networks learn very well from structured data. However, human knowledge, common sense, and experiences are not necessarily easy to express as structured data. This limits the ability of neural networks to learn from humans. This study attempts to fill the gap and enhance the learning ability of neural networks. This paper explains the structure of the neural network that supports this objective and the results of the initial experiments in transferring human knowledge to neural networks.

A long period grating (LPG) operating in the visible wavelength range functionalised with sensitive dyes is reported. Two different sensing mechanisms transmission based, using intensity ratio;and refractive index change based, using the PMTP attenuation bands shift are presented. The visible range LPG’s with phase matching turning point (PMTP) ~700 nm was fabricated using amplitude mask laser inscribing approach on a hydrogen loaded SM600 fibre. Ammonia sensitive thin film based on diazonium resin (DAR) and tetrakis-(4-sulfophenyl)porphine (TSPP) dye was deposited via layer-by-layer deposition on LPG fibre and glass substrate. Glass substrate coated by DAR-TSPP was used to calculate the complex refractive index (RI) difference. The response of the visible LPG was compared to an infrared LPG with a same coating. © 2023 SPIE.

Routing Light Emission from Monolayer MoS2 by Mie Resonances of Crystalline Silicon Nanospheres

A dielectric Mie-resonant nanoantenna is capable of controlling the directionality of the emission from nearby quantum emitters through the excitation of multiple degenerate Mie resonances. A crystalline silicon nanosphere (Si NS) is a promising candidate for a dielectric nanoantenna because crystalline Si has a large refractive index (3.8 at 650 nm) and the small imaginary part of a complex refractive index (0.015 at 650 nm) as an optical material. In this work, we control the emission directionality of excitons supported by monolayer transition metal dichalcogenides (1L-TMDCs) using a Si NS. We first discuss the condition to extract the emission preferentially towards the Si NS side from the analytical calculations. We then study the photoluminescence (PL) of 1L-TMDCs on which differently sized single Si NSs are placed. We show that the PL spectral shape strongly depends on the emission direction, and that the emission toward the Si NS side (top) with respect to the opposite side (bottom) is the largest at wavelengths between the magnetic dipole and electric dipole Mie resonances of a Si NS. Finally, we quantitatively discuss the spectral shape of the top-to-bottom ratio from numerical simulations. © 2024, CC BY.
