A set of key performance indicators (KPIs) for manufacturing operation management is introduced in the ISO 22400 standard. However, KPIs are only defined at a high abstraction level and this hampers the standard's practical adoption. In this paper, a framework is introduced in order to solve this weakness. Starting from the analysis of the relevant measurements used in the KPIs’ formulas, a classification model is introduced defining three possible application scopes - work orders, work units and production orders - to analyze each basic element of the standard. As a result, the KPIs defined in the ISO 22400 standard are more precisely specified and, as a consequence, also suitable to be straightforwardly implemented in performance measurement systems. © 2018

Stereo vision 3D reconstruction using keypoints matching methods can bring up problems, such as uneven distribution of points, or even mismatches. To solve the problems, we proposed a novel stereo vision 3D reconstruction algorithm based on template matching. First, considering that the similarity between left and right image of binocular camera can be high, template matching can be brought in to minify the searching range of every keypoint, thus enhance the accuracy of matches and make the reconstruction result more complete. The specific process of the proposed method includes the following steps: templates extraction, keypoint density index calculation, template matching, keypoint matching within template matched areas, point cloud generation, and point cloud stitching. Furthermore, a simulation environment was built up in Gazebo, and 3D reconstruction was carried out using the proposed method. Comparison experiment was carried out using brute force keypoint matching method and FLANN. Simulation results showed that the proposed method performed better and improved in both utilization of keypoints and reconstruction result.

The main goal of eNeuron H2020 project (Nov 2020-Oct. 2024, ID: 957779) is to develop innovative tools for the optimal design and operation of local energy communities, integrating distributed energy resources and multiple energy carriers at different scales. This paper presents a review study of the enabling conditions for the deployment of integrated local energy communities (ILECs) in Europe, performed within the project. The enabling conditions are addressed by defining the key actors and their interests in the implementation of an energy community at local level and through a detailed mapping of the enabling and emerging energy and information and communication technologies at both household and community levels. Special focus is also on mapping of the demand-side flexibility technologies to understand the benefits of local flexibility and impacts on the larger systems. In such analysis, the key issues for implementation and adaptation of this new energy paradigm are investigated through covering technological, socio-economic, environmental, and regulatory aspects.

Quadcopter is an unmanned aircraft that could be used as an image recorder at various view angle that can't be placed by a human. This research is done to planning, building and implement a quadcopter that is equipped with a camera. Then, we apply for a tracking object program in the quadcopter which is called image processing. Therefore, this research begins by designing the mechanical and electrical of the quadcopter. While the designing of the software is done by making image processing program using C++. Data collection is done by testing the device in each section. Based on the result of research and testing, the result shows that quadcopter could follow a straight moving human, then it turns 90 to right as far as 10 meters. But, there are any movements that we did not expect before, which is in the altitude of the quadcopter, it because of the instability of the loiter flight mode. © Published under licence by IOP Publishing Ltd.

Respiratory patterns present great variability, both in healthy subjects and in patients with different diseases and forms of nasal, oral, superficial or deep breathing. The analysis of this variability depends, among others, on the device used to record the signals that describe these patterns. In this study, we propose multivariable regression models to estimate tidal volume (V T ) considering different breathing patterns. Twenty-three healthy volunteers underwent continuous multisensor recordings considering different modes of breathing. Respiratory flow and volume signals were recorded with a pneumotachograph and thoracic and abdominal respiratory inductive plethysmographic bands. Several respiratory parameters were extracted from the volume signals, such as inspiratory and expiratory areas (Area ins , Area exp ), maximum volume relative to the cycle start and end (VT ins , VT exp ), inspiratory and expiratory time (T ins , T exp ), cycle duration (T tot ), and normalized parameters of clinical interest. The parameters with the greatest individual predictive power were combined using multivariable models to estimate V T . Their performance were quantified in terms of determination coefficient (R 2 ), relative error (E R ) and interquartile range (IQR). Using only three parameters, the results obtained for the thoracic band (VT exp , T tot , Area exp ) were better than those obtained from the abdominal band (VT exp , T ins , Area ins ) with R 2 = 0.94 (IQR: 0.07); E R = 6.99 (IQR: 6.12) vs R 2 = 0.91 (IQR: 0.09), E R = 8.70 (IQR: 4.62). Overall performance increased to R 2 = 0.97 (IQR: 0.02) and E R = 4.60 (IQR: 3.68) when parameters from the different bands were combined, further improving when was applied to segments with different inspiration–expiration patterns. In particular, the nose-nose E R = 1.39 (IQR: 0.73), nose-mouth E R = 2.11 (IQR: 1.23) and mouth-mouth E R = 2.29 (IQR: 1.44) patterns showed the best results compared to those obtained for b

The commutation failures seriously threaten the safe operation of hybrid AC/DC grid. Considering that commutation failure occurs only on the inverter side, it is very important to study the voltage controlled current source model of LCC HVDC single terminal measurement information with high equivalent accuracy, which is very important for the practicality of real-time electromagnetic transient simulation of LCC HVDC dynamic phasor model. In order to this problem, this paper further discusses the single terminal equivalent model of LCC HVDC system which does not depend on the measurement information of DC sending end AC system, and explores the estimation method of single terminal fast transient response of complex AC/DC coupling faults induced by AC side fault of LCC HVDC inverter station and participation of DC control separation. The error distribution of single terminal equivalent calculation is quantitatively analyzed to lay a foundation for the follow-up protection and control technology research. © 2020 IEEE.

Accurate monitoring of respiratory activity can lead to early identification and treatment of possible respiratory failure. However, spontaneous breathing can vary considerably. To quantify this variability, this study aimed at comparing the breathing pattern characteristics obtained from several recording sensors during different breathing types. Respiratory activity was recorded with a pneumotachograph and two inductive plethysmographic bands, thoracic and abdominal, in 23 healthy volunteers (age 21.5±1.2 years, 13 females). The subjects were asked to breathe at their natural rate, in successive stages: first freely, then through their nose, nose and mouth, mouth alone, and finally deep and shallow. Both band signals were compared to the pneumotach-derived (gold standard) volume signal. The time series of inspiratory and expiratory duration, total cycle duration and tidal volume were estimated from each of these signals, and also from the sum of the thoracic and abdominal bands. This composite signal showed the highest correlation with the volume signal for almost all subjects, and also had a significantly higher correlation with those obtained from the gold standard volume, compared to either band. In general, breathing parameters increased from basal to nose-mouth breathing, had a minimum in shallow breathing and a maximum in deep breathing. Women exhibited a significantly longer exhalation phase than men during deep breathing, in the combined bands and the gold standard volume. In conclusion, variations in respiratory cycle morphology in different breathing types can be well captured by the simple addition of abdominal and thoracic band *** Relevance— Breathing pattern variability can be identified by the combination of abdominal and thoracic bands.

In this paper we consider a minimal, linear, time-invariant (LTI) system of order n, large. Our goal is to compute an approximation of order ν 2 norm of the approximation error. For this, in the family of ν order parametrized models that match ν moments we impose ℓ+k linear constraints yielding a subfamily of models with ℓ poles and k zeros imposed. Then, in the subfamily of ν order models matching ν moments, with ℓ poles and k zeros imposed we propose an optimization problem that provides the model yielding the minimal H 2 -norm of the approximation error. We analyze the first-order optimality conditions of this optimization problem and compute explicitly the gradient of the objective function in terms of the controllability and the observability Gramians of the error system. We then propose a gradient method that finds the (optimal) stable model, with fixed ℓ poles and k zeros.

In this paper, an adaptive sliding mode (ASMC) controller designed for a multi-inputs and multi-outputs (MIMO) robotic arm nonlinear manipulator system. The controller is designed based on Lyapunov theorem to achieve a robust trajectory tracking taking into consideration the system's uncertainties in addition to reducing the effect of chattering problem associated with the traditional sliding mode control. It's found that, even in the presence of the parameters' uncertainties, the performance of the proposed controller for the trajectory tracking is robust. Furthermore, chattering is significantly reduced. © 2019 IEEE.

The controller design for a high-order object prone to oscillations under sufficient of interest in automation and robotics is being solved. For the first time, the square root in the error growth detector used as a component for the cost function calculating unit is proposed. Justification for this proposal is given, and the effectiveness of such modification of the cost function is demonstrated on example of object. Software SimInTech was used for some calculations. It was shown that strong procedures of optimization are wide necessary for controller design.
