Systematic review of features for co‐simulating security incidents in Cyber‐Physical Systems

Cyber‐Physical Systems (CPS) and Internet‐of‐Things (IoT) plus energy are the enabling technology of modern power systems also known as the Smart Grid (SG). A SG may consist of thousands of interconnected components communicating and exchanging data across layers that stretch beyond technical capabilities, for instance, markets and customer interactions. Cyber‐physical security is a major source of concern due to the high reliance of the SG on Information and Communication Technologies (ICT) and their widespread use. Addressing security requires developing modeling and simulation tools that approximate and replicate adversarial behavior in the SG. These tools have in fact two simulators, one handling continuous power flows and another for capturing the discrete behavior when communicating across CPS or IoT components. The technique of composing two models of computation in a global simulation of these coupled systems is called co‐simulation. Although there are many frameworks and tools for co‐simulation, the set of features for modeling cyber‐physical security incidents in the SG lacks thorough understanding. We present a systematic review of features and tools for co‐simulating these concerns in CPS. We also highlight and discuss research gaps with respect to the most used tools in industry and academia and comment on their relevant features.
Eddy current loss analysis of open-slot fault-tolerant permanent-magnet machines based on conformal mapping method

This paper proposed an analytical method, based on conformal mapping (CM) method, for the accurate evaluation of magnetic field and eddy current (EC) loss in fault-tolerant permanent-magnet (FTPM) machines. The aim of modulation function, applied in CM method, is to change the open-slot structure into fully closed-slot structure, whose air-gap flux density is easy to calculate analytically. Therefore, with the help of Matlab Schwarz-Christoffel (SC) Toolbox, both the magnetic flux density and EC density of FTPM machine are obtained accurately. Finally, time-stepped transient finite-element method (FEM) is used to verify the theoretical analysis, showing that the proposed method is able to predict the magnetic flux density and EC loss precisely.
Invisible bondage: Mobility and compulsion within Sri Lanka’s global assembly line production

Female workers who enter factory work in Sri Lanka’s Free Trade Zones (FTZs) via contractors are not forced to join or remain in contractor labor pools. This paper, however, argues that such workers nevertheless remain unfree due to cultural and emotional bonds that restrict labor mobility. By analyzing how contracted workers’ entry and mobility within work get shaped by a coalition of patriarchal agents—parents, contractors and factory management—the paper demonstrates how compulsive emotional conditions, that I term “invisible bondage,” are produced and maintained. While the degree of compulsion varies depending on the particular form of labor contracting (i.e., Tamil women from the war torn areas recruited by military personnel, or daily hired workers), I show that all labor contracting for global production represent how forms of unfreedoms are interwoven into supposedly free market relations of production. Such invisible controls, I argue, are essential for neoliberal capitalism to thrive.
Evaluation of VTH and RON Drifts during Switch-Mode Operation in Packaged SiC MOSFETs

In this paper, we investigate the evolution of threshold voltage (VTH) and on-resistance (RON) drifts in the silicon carbide (SiC) power metal-oxide-semiconductor field-effect transistors (MOSFETs) during the switch-mode operation. A novel measurement setup for performing the required on-the-fly characterization is presented and the experimental results, obtained on commercially available TO-247 packaged SiC devices, are reported. Measurements were performed for 1000 s, during which negative VTH shifts (i.e., VTH decrease) and negative RON drifts (i.e., RON decrease) were observed. To better understand the origin of these parameter drifts and their possible correlation, measurements were performed for different (i) gate-driving voltage (VGH) and (ii) off-state drain voltage (VPH). We found that VTH reduction leads to a current increase, thus yielding RON to decrease. This correlation was explained by the RON dependence on the overdrive voltage (VGS–VTH). We also found that gate-related effects dominate the parameter drifts at low VPH with no observable recovery, due to the repeated switching of the gate signal required for the parameter monitoring. Conversely, the drain-induced instabilities caused by high VPH are completely recoverable within 1000 s from the VPH removal. These results show that the measurement setup is able to discern the gate/drain contributions, clarifying the origin of the observed VTH and RON drifts.
Proven and Reliable Methods of Early Speech Therapy Intervention for Children with Autism Spectrum Disorder

The purpose of our research is to identify the effective tools for early Speech therapy intervention in working with children with Autism Spectrum Disorder (ASD) in order to provide their speech forming and development by using confinable methods. Besides, the purpose includes the thesis about high effectivity of systematic complex approach in case of work with ASD. Current research is based on theoretical materials from professional literature and on 14 years of own personal speech therapy professional experience. It is concluded that methods used in the speech therapy work with ASD children are effective in application, but as a result of the individual approach of the child's speech and communication, their combination at the appropriate stage of development provides a higher result. We emphasize the development of established methods and means of early speech intervention in the work with ASD, the development of a systemic approach and the introduction of conditions that will facilitate their early speech therapy intervention.
Medication errors: a focus on nursing practice

Health departments endeavor to give care to individuals to remain in healthy conditions. Medications errors (MEs), one of the most types of medical errors, could be venomous in clinical settings. Patients will be harmed physically and psychologically, in addition to adverse economic consequences. Reviewing and understanding the topic of medication error especially by nurses can help in advancing the medical services to patients. A search using search engines such as PubMed and Google scholar were used in finding articles related to the review topic. This review highlighted the classifications of MEs, their types, outcomes, reporting process, and the strategies of error avoidance. This summary can bridge and open gates of awareness on how to deal with and prevent error occurrences. It highlights the importance of reporting strategies as mainstay prevention methods for medication errors. Medication errors are classified based on multifaceted criteria and there is a need to standardize the recommendations and make them a central goal all over the globe for the best practice. Nurses are the frontlines of clinical settings, encouraged to be one integrated body to prevent the occurrence of medication errors. Thus, systemizing the guidelines are required such as education and training, independent double checks, standardized procedures, follow the five rights, documentation, keep lines of communication open, inform patients of drug they receive, follow strict guidelines, improve labeling and package format, focus on the work environment, reduce workload, ways to avoid distraction, fix the faulty system, enhancing job security for nurses, create a cultural blame-free workspace, as well as hospital administration, should support and revise processes of error reporting, and spread the awareness of the importance of reporting.
Optimal bus coding for OR-chained buses

This letter presents a novel bus coding technique suitable for a bus with OR chaining that requires data parking at the end of data transmission. Based on the fact that the data parking state is known a priori, the proposed technique encodes the last sequential data value by jointly considering two switching activities, one that occurred due to a change in valid data values and the other that will be subsequently occurred by data parking. Compared to the conventional bus coding scheme that picks a codeword that minimizes only the former, the proposed technique can achieve > 3% additional saving of switching activity in average. Evaluation results based on 22- nm CMOS technology show that the proposed scheme, even with its higher encoding energy, can obtain the lower total energy for > 0.59 mm bus length in comparison with the conventional data bus invert technique.
Investigation on the Influence Caused by Shield Tunneling: WSN Monitoring and Numerical Simulation

Traditional monitoring techniques are faced with the problems of low acquisition frequency and easy to be affected by the construction environment during the shield tunneling, which cannot meet the actual needs of timeliness monitoring of surrounding environmental impact on shield tunnel construction. Based on this actual demand, a wireless sensor network (WSN) system was used to monitor the response of shield tunnel segments and surrounding buildings during the shield tunneling in this study. According to the result of the signal transmission test, an optimization scheme of microelectromechanical system (MEMS) sensor layout is designed to improve the monitoring efficiency of the WSN system. Through the comparative analysis of WSN system monitoring data and traditional monitoring data, it is found that, with the increasing distance between the monitoring section and the tunnel face, the convergence value of tunnel lining clearance gradually tends to be stable, and the wireless monitoring results of transverse clearance convergence of the tunnel in this section are consistent with the overall deformation trend of the convergence gauge monitoring results. This study also simulated the shield tunneling adjacent buildings using a nonlinear finite element method. A parameter sensitivity analysis of the support pressure of the excavation face and the grouting pressure at the tail of the shield is carried out. The results show that the surface settlement can be reduced by properly increasing the grouting pressure and the support pressure of the excavation face. Moreover, increasing the support pressure of the excavation face has a better inhibition effect on the settlement of the surface soil than increasing the grouting pressure.
A New Support Vector Regression Model for Equipment Health Diagnosis with Small Sample Data Missing and Its Application

Actually, it is difficult to obtain a large number of sample data due to equipment failure, and small sample data may also be missing. This paper proposes a novel small sample data missing filling method based on support vector regression (SVR) and genetic algorithm (GA) to improve equipment health diagnosis effect. First, the genetic algorithm is used to optimize support vector regression, and a new method GA-SVR can be proposed. The GA-SVR model is trained by using other data of the variable to which the missing data belongs, and the single-variable prediction method can be obtained. The correlation analysis is used to reconstruct the training set, and the GA-SVR is trained by using the data of the variables related to the missing data to obtain the multivariate prediction method. Then, the dynamic weight is presented to combine the single-variable prediction method with the multiple-variable prediction method based on certain principles, and the missing data are filled with the combined prediction methods. The filled data are used as input of GA-SVM to diagnose equipment failure. Finally, a case study is given to verify the applicability and effectiveness of the proposed method.
MXene‐on‐Paper Coplanar Microsupercapacitors

A simple and scalable direct laser machining process to fabricate MXene‐on‐paper coplanar microsupercapacitors is reported. Commercially available printing paper is employed as a platform in order to coat either hydrofluoric acid‐etched or clay‐like 2D Ti3C2 MXene sheets, followed by laser machining to fabricate thick‐film MXene coplanar electrodes over a large area. The size, morphology, and conductivity of the 2D MXene sheets are found to strongly affect the electrochemical performance due to the efficiency of the ion‐electron kinetics within the layered MXene sheets. The areal performance metrics of Ti3C2 MXene‐on‐paper microsupercapacitors show very competitive power‐energy densities, comparable to the reported state‐of‐the‐art paper‐based microsupercapacitors. Various device architectures are fabricated using the MXene‐on‐paper electrodes and successfully demonstrated as a micropower source for light emitting diodes. The MXene‐on‐paper electrodes show promise for flexible on‐paper energy storage devices.
Analytical and Experimental Investigation of Stabilizing Rotating Uncooperative Target by Tethered Space Tug

Attitude stabilization of a massive rotating uncooperative target by a tethered space tug is studied for orbit maneuvering in the postcapture operation analytically and experimentally. The perturbed orbital propagation of the tethered space system is described with nonsingular orbital elements and the relative equations of motion of the tethered space system, including the tether libration and attitudes of target and tug, are established in the orbital frame. The tether tension control, the tug's attitude control, and the combination control of them are designed to suppress the attitude and libration motions of the target/tug and the tethered space system with bounded stability. The control law's effectiveness is demonstrated by simulation and then validated experimentally by a microgravity testbed with two tethered free-floating air-bearing satellite simulators.
Gases for Electrical Insulation and Arc Interruption: Possible Present and Future Alternatives to Pure SF6

The electric power Industry's preferred gaseous dielectric (besides air), sulfur hexafluoride (SFg), has been shown to be a greenhouse gas. In this report we provide information that is useful In Identifying possible replacement gases, in the event that replacement gases are deemed a reasonable approach to reducing the use of SFg in high voltage electrical equipment. The report focuses on the properties of SFg as a dielectric gas and on the data available for possible alternatives to pure SFg (i.e., SFg alone). On the basis of published studies and consultation with experts in the field, it was attempted to identify alternative dielectric gases to pure SFg for possible immediate or future use in existing or modified electrical equipment. The possible alternative gases are discussed as three separate groups: (i) mixtures of SFg and nitrogen for which a large amount of research results are available; (ii) gases and mixtures (e.g., pure Nj, low concentrations of SFg in Ng, and SFg-He mixtures) for which a smaller yet significant amount of data are available; and (iii) potential gases for which little experimental data are available.
Oil Palm Tree Detection and Health Classification on High-Resolution Imagery Using Deep Learning

Combining modern technology and agriculture is an important consideration for the effective management of oil palm trees. In this study, an alternative method for oil palm tree management is proposed by applying high-resolution imagery, combined with Faster-RCNN, for automatic detection and health classification of oil palm trees. This study used a total of 4172 bounding boxes of healthy and unhealthy palm trees, constructed from 2000 pixel × 2000 pixel images. Of the total dataset, 90% was used for training and 10% was prepared for testing using Resnet-50 and VGG-16. Three techniques were used to assess the models’ performance: model training evaluation, evaluation using visual interpretation, and ground sampling inspections. The study identified three characteristics needed for detection and health classification: crown size, color, and density. The optimal altitude to capture images for detection and classification was determined to be 100 m, although the model showed satisfactory performance up to 140 m. For oil palm tree detection, healthy tree identification, and unhealthy tree identification, Resnet-50 obtained F1-scores of 95.09%, 92.07%, and 86.96%, respectively, with respect to visual interpretation ground truth and 97.67%, 95.30%, and 57.14%, respectively, with respect to ground sampling inspection ground truth. Resnet-50 yielded better F1-scores than VGG-16 in both evaluations. Therefore, the proposed method is well suited for the effective management of crops.
Robust Emergency Relief Supply Planning for Foreseen Disasters Under Evacuation-Side Uncertainty

For foreseen natural disasters (e.g., hurricanes or floods), the uncertainties faced in relief logistics primarily stem from evacuation activities. We present a strategic planning problem to supply relief items by considering uncertainties in disaster location, intensity, duration, and evacuee compliance. To ensure time- and cost-effectiveness in relief distribution, we develop a robust optimization model to determine centralized supply locations, and supply quantities for different transportation modes in a five-tier network. In doing so, we consider the interaction between evacuation and supply-side activities and capture the inherent uncertainties using a combination of event and box uncertainty representations. Our model provides a decision maker with the flexibility of including or excluding the time dependency of evacuation-related uncertainties. Accordingly, it suggests a threshold time window for relief distribution, beyond which either the system cost increases or the benefits of early distribution diminish. Although the model primarily aids a policymaker in strategic preparedness, its tactical variant can aid the efficient distribution. We devise an enhanced Benders decomposition-based efficient solution method to solve realistic-size problems. In a case study using geographic information system data, we highlight the complex dynamics among various system components and discuss the resulting time-cost trade-offs that also influence the network structure.
Squint-less arc array for near-field focusing in wideband systems

In this paper, the arc array for squint-less near-field focusing is used, theoretically analyzed, and verified. The arc array is designed to overcome the squint phenomenon in the near-field and transfers the maximum power at a focused distance. The implemented transmitter is composed of vivaldi antennas with a spacing and operates at a frequency of 5.8 GHz. In addition, the design method of the arc array is proposed, considering the focused distances. In the experiments, the bending degree of the arc array is when the focused distance is 0.5 m. At a fractional bandwidth of 27.5%, the focus position is shifted 32%. On the other hand, in the arc array, the focus position is not shifted. Experimental results from the implemented arc array show good agreement with the proposed theory.
Terraced Landforms Onshore and Offshore the Cilento Promontory (South-Eastern Tyrrhenian Margin) and Their Significance as Quaternary Records of Sea Level Changes

Climate change and tectonic uplift are the dominant forcing mechanisms responsible for the formation of long and narrow terraced landforms in a variety of geomorphic settings; and marine terraces are largely used to reconstruct the Quaternary glacial and interglacial climates. Along the Mediterranean coast, a considerable number of popular scientific articles have acknowledged a range of marine terraces in the form of low-relief surfaces resulting from the combined effects of tectonic uplift and eustatic sea-level fluctuations, as relevant geomorphological indicators of past sea-level high-stands. With the exception of a few recent studies on the significance of submarine depositional terraces (SDT), submerged terraced landforms have been less investigated. By integrating different marine and terrestrial datasets, our work brings together and re-examines numerous terraced landforms that typify the Cilento Promontory and its offshore region. In this area, studies since the 1960s have allowed the recognition of well-defined Middle to Upper Pleistocene marine terraces on land, while only a few studies have investigated the occurrences of late Pleistocene SDT. Furthermore, to date, no studies have consistently integrated findings. For our work, we correlated major evidence of emerged and submarine terraced landforms in order to support an improved understanding of the tectono-geomorphological evolution of the Cilento Promontory and to further clarify the geomorphological significance of submerged terraces.
Integrated universal HIV testing with public health care program: an exploratory study of 1.1 million people from Eastern China

Objective By investigating the large-scale HIV antibody screening of more than 1 million people, we explored weather the strategy of integrated universal HIV testing in a public health care program was useful. Methods We used a multi-stage stratified random cluster sampling method in a community-based investigation of 30 sample points within 9 counties in the Zhejiang province. The HIV antibody was detected, and demographic information was collected. Results Of the 1 113 030 people screened for HIV, 310 tested positive (adjusted HIV prevalence, 3.45/10000; 95% confidence interval [CI], 3.41–3.48). The HIV prevalence was higher in men(5.62/10000 ) than in women(1.17/10000) of all ages; those in the 25–34 and 35–44 age groups were highest (compared with the < 15 age group, the adjusted odds ratios were 25.69 and 18.48, respectively). The HIV prevalence at the medium gross domestic product (GDP) level (adjusted HIV prevalence, 5.28/10000; 95% CI, 4.53–6.04) was significantly higher than those at high and low GDP levels Especially in the male 25–34 and 35–44 age groups. Compared with the native HIV positive population, the migrants were younger, did not have a stable sexual partner, and had a lower level of education. Conclusion By using universal HIV testing integrated into a public health care program was feasible and (perhaps) effective in finding new HIV cases. We should pay more attention to the 25–44 age male population, as well as migrants in our HIV/AIDS control strategies, especial in industrial activity district.
