In this paper, we propose a standing assistance scheme that uses a patient's own physical strength. In previous studies, conventional assistive robots did not require patients to use their own physical strength to stand, which leads to decreased strength in the elderly. Therefore, an assistive robot that allows patients to maximally use the physical strength they possess is desired. To realize this objective, we propose a standing assistance scheme that performs two functions, namely, motion assistance using a patient's own physical strength and posture adjustment. In general, human movements consist of voluntary movement, which mainly generates body motion, and posture adjustment, which keeps the body stable during motion. Our proposed scheme provides the minimum force that enables voluntary movement by patients with their remaining physical strength while keeping their body stable by performing posture adjustment. To perform these two functions simultaneously, we propose a body movement vector for dividing human motion into a voluntary movement and a posture adjustment action. A prototype assistive robot fabricated based on the proposed idea helped elderly patients stand using their remaining physical strength maximally by performing the two assistive functions simultaneously.

The V/sTOL capability of the AV-8B Harrier is provided through a sophisticated combination of vectored thrust and aerodynamic technology. The proper interaction of the nozzle thrust and flap system is of extreme importance. specific combinations of nozzle angle and flap position are employed to optimize both jet lift and aerodynamic lift. However, if the proper flap-nozzle position schedule is violated, the resulting thrust and flap impingement may cause a severe nose-down pitching moment sufficient to override the pilot control. Depending upon ground proximity, this condition creates a hazard which causes great potential for loss of aircraft and/or pilot. Flap impingement hazard was identified on the AV-8B aircraft as a potential catastrophic flight hazard. In response, a requirement was established to 1) study the severity of the flap impingement hazard on the AV-8B, 2) devise flight operational procedures which would minimize pilot exposure to the hazard potential and the resulting pilot control problems during flight, and 3) devise a training capability to familiarize pilots with flap impingement hazard characteristics and recovery procedures. This paper comprises the results of a study which utilized piloted flight simulation and fleet simulation trainers to meet these requirements.

It is the key successful factors for the manufacture industry that create and select the key parameters in product design to match customer requirements in multimedia. Previous literature studies are focused on the development of customer requirements or parameter selection in product design but not the development of customer demand modelling and product parameter selections in multimedia. In this way we can achieve the purpose of meeting customer demand for product design in multimedia. Kano is a successful method to solve the customer requirements selections issues. And, the theory of inventive problem solving (TRIZ) method is a method to solve the contradiction of product design. Therefore;the integration of the Kano and theory of inventive problem solving (TRIZ) methods is proposed to solve the cable product design in multimedia. This algorithm is also verified in an electronic manufacture. In summary, the proposed algorithm can be helpful by creating a product system in multimedia in this study.

One of the human's roles in modern, complex technological systems is to deal with unanticipated situations not treated explicitly in the design. In order to assess the relative effectiveness of automation and interface presentation, an experiment has been conducted with a micro-world that has an automatic diagnostic tool for fault location without fault quantification. Combined with the micro-world are two kinds of interface presentation. One is a traditional P&ID graphical interface and the other an ecological interface that aims to make visible the ecology of work. A new icon has been designed for a heat exchanger, which is a fundamental piece of equipment in the thermodynamic process simulated here. Two types of fault, pipe break and leak in various locations of the process are simulated, and observations of the subjects' responses have been made for each interface which is treated as a between-subject factor. Our experimental results show no difference between the two interfaces for pipe break transient, while the ecological interface gives better performance for some pipe leaks. Investigations from cognitive work analysis have been made to make dear this somewhat "unpredicted" result.

In the Fiscal Year 1996 National Defense Authorization Act, Congress amended the Clean Water Act to provide the Department of Defense and the Environmental Protection Agency authority to jointly establish standards for incidental discharges from Armed Forces' vessels. The uniform national standards would apply to discharges from vessels of the Navy, Military sealift Command, Army, Marine Corps, Air Force, and Coast Guard to the navigable waters and contiguous zone of the U.s. and its territories. Uniform National Discharge standards (UNDs) will require control of discharges, by either a technology or management practice. UNDs will facilitate the Armed Forces' ability to better design and build future vessels to be environmentally sound and to maintain the operational flexibility of Armed Forces' vessels both domestically and internationally. The development of standards for Armed Forces' vessel discharges may have greater impact on naval engineering requirements for future vessels than any other single environmental issue, These standards are expected to stimulate the development of innovative vessel pollution control technologies, which on be used for both Armed Forces' vessels and commercial shipping vessels. This paper provides an overview of UNDs development, summarizes the results of UNDs Phase I, provides a summary overview of the preliminary approach for accomplishing UNDs Phase Il, and discusses implications for future naval engineering efforts.

Deep learning has excellent learning and feature classification abilities, extracting features in massive, multi-source, and high-dimensional measurement data. It also diagnoses and generalizes models without relying on manual intervention. Thus, it is widely used in equipment fault diagnosis. We introduce the common models of deep learning: deep confidence network, convolutional neural network, and automatic encoder. Using deep learning, the fault diagnosis of rolling bearings is executed, and the result provides the basis for future development.

In diagnostic radiology, the radiation interaction probability in matter is a strong function of the X-ray energy. The knowledge of the X-ray energy spectral distribution allows optimizing the radiographic imaging system in order to obtain high quality images with as low as reasonably achievable patient doses. In this study, transmitted X-ray spectra through dentin and enamel that are existing materials in intra-oral radiology were experimentally determined in an X-ray equipment with 40-70 kV variable range. Dentin and enamel samples with 0.4-3.8 and 0.6-2.6 mm thick were used as attenuators. X-ray transmitted spectra were measured with XR-100T model CdTe detector and half-value layers (HVL) were determined. Characteristics of both dentin and enamel transmitted spectra showed that they have differences in the penetration power in matter and in the spectrum distribution. The results will be useful for phantom developments based on dentin and enamel for image quality control in dental radiology. © 2011 Elsevier Ltd. All rights reserved.

The electric energy produced by photovoltaic systems is a function of several variables that present random behavior, such as solar irradiance, ambient temperature, wind speed, and relative humidity. several models describe the energy produced by these systems, which reflect the various factors that influence the generation and how significant these influences are. In this way, the present work aims to compare some panel temperature models and the electrical energy produced from a photovoltaic system located in the Midwest of Brazil. The applied methodology aims to evaluate the expected averages and standard deviations of the monthly synthetic series of generated energy to identify the main random variables that influence the electric generation. The results indicate the model that best describes the physical system concerning the randomness of the variables involved, the photovoltaic technology, the location, and the measurement period. © 2021, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).

Because imitation learning relies on human demonstrations in hard-to-simulate settings, the inclusion of force control in this method has resulted in a shortage of training data, even with a simple change in speed. Although the field of data augmentation has addressed the lack of data, conventional methods of data augmentation for robot manipulation are limited to simulation-based methods or downsampling for position control. This paper proposes a novel method of data augmentation that is applicable to force control and preserves the advantages of real-world datasets. We applied teaching-playback at variable speeds as real-world data augmentation to increase both the quantity and quality of environmental reactions at variable speeds. An experiment was conducted on bilateral control-based imitation learning using a method of imitation learning equipped with position-force control. We evaluated the effect of real-world data augmentation on two tasks, pick-and-place and wiping, at variable speeds, each from two human demonstrations at fixed speed. The results showed a maximum 55% increase in success rate from a simple change in speed of real-world reactions and improved accuracy along the duration/frequency command by gathering environmental reactions at variable speeds.

Acute intracerebral hemorrhage (ICH) entity accounts for 10 to 15% of all strokes and is associated with a higher mortality rate ischemic stroke or subarachnoid hemorrhage. Causes of ICH are divided into primary, and secondary, including vascular malformation and tumorous. Primary ICH accounts for approximately 80% of all ICH cases. Vascular anomalies rank as the second most common cause of spontaneous ICH overall. Furthermore, hemorrhage resulting from brain tumors can occur in up to 10% of all primary or metastatic tumors. Early recognizing of these three causes of bleeding is critical for clinicians in precise diagnosis, effective treatment management, and helps avoid delayed diagnosis. We proposed a radiomics approach for classifying multiple causes of acute ICH as vascular malformation, tumorous, and primary-related hematoma. Non-contrast brain computed tomography with clinical features was used as input. The regions of both hematoma and perihematomal edema were delineated by using manual segmentation approach. Four feature selection methods were adopted. Also, three classification models were investigated in this study. The results showed that using the features selected by F-value applied with sVM classifier outperformed the other models, achieving weighted average accuracy (± sD) of 0.84 (± 0.07). Additionally, the model demonstrated average sensitivity and positive predictive value of 0.84 (± 0.06) and 0.86 (± 0.05), respectively. We also evaluate the overall performance of discriminating each class from the rest using AUC. The result suggested that our proposed model achieved the weighted average AUC of 0.90. Our proposed method highlights the potential in identifying multiple causes of acute and nontraumatic ICH, which has not been previously explored.
