Abstract (sommario):

A unified control method of comprehensive compensation system based on CS- APF and SVC is introduced in this paper. SVC is composed of thyristor controlled reactor (TCR) and fixed capacitor (FC). For the CS- APF control, a feedforward control for harmonic compensation of SVC and load is applied. The CS- APF is enabled to optimize the var compensation performance of SVC. Finally, the simulation results show that the system can effectively compensate reactive power and eliminate harmonic currents.

Abstract (sommario):

Abstract The creation of the Rorschach Performance Assessment System (R-PAS) requires research that allows its use in the Brazilian population. The Formal Quality (FQ) category is essential both for clinic and research. The aim of this study was to compare form quality variables in Rorschach protocols from psychiatric patients and ratings coded in the Comprehensive System (CS) and R-PAS. The sample comprised 206 Rorschach protocols from adult patients in psychiatric treatment, who were also assessed by SCID-I and SCID-II. Most protocols were administered in the CS and recoded according to the R-PAS. The kappa coefficient was calculated, and we compared the means of these variables in both systems. The kappa results varied from almost perfect to substantial consistency for all variables, however, the descriptive statistics confirmed that the R-PAS elicits more FQ Ordinary coding while the CS elicits more FQ minus coding.

Abstract (sommario):

The Rorschach Comprehensive System (CS) scores of D, Adj.D, m, and SumY are thought to indicate feelings associated with stressful experiences. In this study, 92 patients with chronic inflammatory bowel disease (IBD) were assessed with the Rorschach CS, the Hospital Anxiety and Depression Scale (HADS) for psychological distress, and standard biomedical measures for disease activity (DA) over a period of 6 months. Stress was defined as the combined assessment of the somatic (DA) and psychological (HADS) components by creating groups of patients with and without biopsychological distress. Using a cross-sectional study design, we could associate the CS variables of stress control (D, Adj.D, es, and SumY) and negative affect (DEPI) to poor somatic and psychological health status (effect size ranging from .37 to .49). Longitudinal, hierarchical regression analysis showed that baseline CS variables (particularly D < 0 and higher SumY) explained a significant amount (9%) of the disease activity aggravation, and that they – particularly D and Adj.D – independently predicted biopsychological distress aggravation measured 6 months after the Rorschach administration and controlled for biomedical and sociodemographic factors (37% of shared variance). Confirming previous findings, this study showed that D/Adj.D and SumY were reliable, stable indicators of the stressful experience, considered as the joint combination of the psychological and the somatic components.

Testo completo

Abstract (sommario):

In information security, it is widely accepted that the more authentication factors are used, the higher the security level. However, more factors cannot guarantee usability in real usage because human and other non-technical factors are involved. This paper proposes the use of all possible authentication factors, called comprehensive-factor authentication, which can maintain the required security level and usability in real-world implementation. A case study of an implementation of a secure time attendance system that applies this approach is presented. The contribution of this paper is therefore to provide a security scheme seamlessly integrating all classical authentication factors plus a location factor into one single system in a real environment with a security and usability focus. Usability factors emerging from the study are related to a seamless process including the least number of actions required, the lowest amount of time taken, health safety during the pandemic, and data privacy compliance.

Abstract (sommario):

Timely maintenance of sewers is essential to preventing reduced functionality and breakdown of the systems. Due to the high costs associated with inspecting a sewer system, substantial research has focused on sewer deterioration modeling and identification of the most useful features. However, there is a lack of consensus in the findings. This study investigates how the feature importance depends on the definition of bad pipes and how the feature importance changes between utilities with similar data bases. A dataset containing 318,457 pipes from 35 utilities with a condition state (CS) ranging from one to four was used. The dataset was cleaned, and a backward step analysis (BSA) was applied to two ways of binarizing the CS. Additionally, a BSA was applied for each utility with ≥100 pipes in CS four. The results showed that a selective definition of bad pipes reduced the performance and changed the order of which features contributed the most. In each case, either year of construction, age, groundwater, year of rehabilitation, or dimension was the most important feature. On average 6.5 features contributed to the utility-specific models. The feature analysis was sensitive to the inspection strategy, the size of the dataset, and interdependency between the features.

Abstract (sommario):

Abstract The ethical principles of psychological assessment include the need to use reliable tests to meet the demands of the emerging population. Therefore, the present study sought to provide evidence of validity of the Zulliger Comprehensive System (Zulliger Test in the Comprehensive System) considering the constructs: self-perception and interpersonal relationships. A total of 61 older adults of both sexes participated in the study; 30 had Parkinson’s disease (clinical group) and 31 were healthy (non-clinical group). The clinical group showed an increase in the following variables: Human detail (p = 0.02, d = 0.50); Morbid responses (p = 0.025, d = 0.62); Vista responses (p = 0.016, d = 0.72), Food Responses (p = 0.021, d = 0.61) and Decrease in human detail fictional (p = 0.012, d = -0.65) and in Personalized Responses (p = 0.003, d = -0.48). There was a positive relationship between the Zulliger Test in the Comprehensive System variables and age, income, and disease severity and a negative relationship between the Zulliger Test in the Comprehensive System variables and time since diagnosis. The results obtained confirm the validity of the Zulliger Test in the Comprehensive System and encourage further studies.

Abstract (sommario):

The North China Plain (NCP) is one of the most important grain production regions in China. However, it currently experiences water shortage, severe nonpoint source pollution, and low water and N use efficiencies (WUE and NUE). To explore sustainable agricultural development in this region, a field experiment with different cropping systems was conducted in suburban Beijing. These cropping systems included a winter wheat and summer maize rotation system for one year (WM), three harvests (winter wheat-summer maize-spring maize) in two years (HT), and continuous spring maize monoculture (CS). Novel ways were explored to improve WUE and NUE and to reduce N loss via the alternative cropping system based on the simulation results of a soil-crop system model. Results showed that the annual average yields were ranked as follows: WM > HT > CS. The N leaching of WM was much larger than that of HT and CS. WUE and NUE were ranked as follows: WM < HT < CS. Comprehensive evaluation indices based on agronomic and environmental effects indicated that CS or HT have significant potential for approaches characterized by water-saving, fertilizer-saving, high-WUE, and high-NUE properties. Once spring maize yield reached an ideal level HT and CS became a high-yield, water-saving, and fertilizer-saving cropping systems. Therefore, this method would be beneficial to sustainable agricultural development in the NCP.

Abstract (sommario):

Cloud computing is the most popular paradigms used today by Industries & individual users to store data. This outsourcing releases user from capital as well as maintenance cost to own their data. But it brings new security challenges such as data integrity & privacy since user has no power of control on his own data. Advances in encryption & authentication techniques has improved security of data at cloud server(CS) but still it is not providing any certificate or assurance about cloud data to user. Most of the times users are not aware of the different controls employed by CS to protect integrity of data. Due to this lack of transparency in system, the user may lose trust on CS. Hence it is a need of user to check integrity of his data at regular intervals. Most of the researchers have given solutions to this problem with the help of cryptography techniques. External parties such as Third-Party Auditors (TPA) are performing audit to verify this remote data on behalf of user. This paper surveys different cryptography mechanisms proposed by different researchers to check integrity of remote data. Finally, we address future research challenges that need to be resolved by researchers to make system more transparent.

Abstract (sommario):

The current study describes the impact of trauma on the perceptual thinking processes of participants who have sustained repeated criminal victimisation in South Africa. Fifteen adult males, (mean age 40.73 years) participated voluntarily in this descriptive study. The Rorschach Inkblot Method (RIM) is the psychometric instrument used to describe the participants and Exner’s Comprehensive System (CS) is the method of interpretation employed. The Perceptual Thinking Index (PTI) is the cluster of variables selected to describe each participant’s level of reality testing and perceptual functioning. Together with this, the D and Adjusted D Score variables are discussed to describe the participants’ overall and current coping capacities. From the research findings yielded in this study, it appears that the majority of these participants (73%) can be described as experiencing problems in terms of their perceptual thinking processes. They are also unable to appropriately engage in accurate reality testing. The results of the research study may serve as an incentive for further studies of this nature as according to the RIM, participants with this level of impaired reality testing generally present with psychotic features. However, these research results were found in participants who present with an absence of a psychotic or any schizophrenic type disorder diagnoses. Other researchers who used the RIM to assess trauma victims have found results similar to this. Furthermore, participants who present with this level of impaired reality testing, generally experience severe problems in coping with basic psychological aspects of daily functioning. This however, does not appear to be the case with this sample group, which was one of the motivating factors for conducting this research. A concluding suggestion is made for possible research into investigating how, and at what expense, other psychological features of functioning are employed, in order to manage in a seemingly well-adaptive manner.

Abstract (sommario):

Safety assessment of nuclear power plant instrumentation and control systems (NPP I&Cs) is a complicated and resource consuming process that is required be done so as to ensure the required safety level and comply to normative regulations. A lot of work have been performed in the field of application of different assessment methods and techniques, modifying them and using their combinations so as to provide unified approach in comprehensive safety assessment. Anyway, performed research have shown there are still challenges to overcome, including rationale and choice of the safety assessment method, verification of assessment results, choosing and applying techniques that support safety assessment process, especially in the nuclear field. In our work we present developed framework that aggregates the most appropriate safety assessment methods typically used for NPP I&Cs. Key features that this framework provides are the formal descriptions of all required input information for every safety assessment method, possible data flows between methods, possible output information for every method. Such representation allows to obtain possible paths required to get necessary indicators, analyze the possibility to verify them by application of different methods that provide same indicators etc. During safety assessment of NPP I&Cs it is very important to address software due to its crucial role in I&C safety assurance. Relevant standards like IEC 60880 [1] and IEC 62138 [2] provide requirements for software related activities and supporting processes in the software safety lifecycle of computer-based I&C systems of nuclear power plants performing functions of safety category A, B and C, as defined by IEC 61226 [3]. Requirements and frameworks provided by IEC 60880 and IEC 62138 for the nuclear application sector correspond to IEC 61508, part 3 [4]. These standards define several types of safety related software and specify particular requirements for each software type. So as to verify software and confirm correspondence to required safety level, different techniques are suggested in normative documents. We share our experience obtained during software failure modes and effect analysis (software FMEA) and software fault insertion (software FIT) processes into FPGA-based platform, NPP I&C systems based on that platform, and RPCT, integrated development environment used by RPC Radiy and end users to design user application logic, specify hardware configuration etc. We apply software FIT to outputs of RPCT, considering source code, configuration files and firmware files. Finally, we provide a case study of application the developed safety assessment framework and software FMEA/FIT practices during practical assessment of FPGA-based NPP I&C system.

Abstract (sommario):

Operating reliability assessment of instrumentation and control systems (I&Cs) is always one of the most important activities, especially for critical domains like nuclear power plants (NPPs). Intensive use of relatively new technologies like field programmable gate arrays (FPGAs) in I&C which appear in upgrades and in newly built NPPs makes task to develop and validate advanced operating reliability assessment methods that consider specific technology features very topical. Increased integration densities make the reliability of integrated circuits the most crucial point in modern NPP I&Cs. Moreover, FPGAs differ in some significant ways from other integrated circuits: they are shipped as blanks and are very dependent on design configured into them. Furthermore, FPGA design could be changed during planned NPP outage for different reasons. Considering all possible failure modes of FPGA-based NPP I&C at design stage is a quite challenging task. Therefore, operating reliability assessment is one of the most preferable ways to perform comprehensive analysis of FPGA-based NPP I&Cs. This paper summarizes our experience on operating reliability analysis of FPGA based NPP I&Cs.

Abstract (sommario):

To deepen the knowledge of the interaction between modern lean burn combustors and high pressure turbines, a non-reactive real scale annular trisector Combustor Simulator (CS) has been assembled at University of Florence, with the goal of investigating and characterizing the combustor aerothermal field as well as the hot streak transport towards the high pressure vanes. To generate hot streaks and simulate lean burn combustor behaviors, the rig is equipped with axial swirlers fed by a main air flow stream that is heated up to 531 K, while liners with effusion cooling holes are fed by air at ambient temperature. Detailed experimental investigations are then performed with the aim of characterizing the turbulence quantities at the exit of the combustion module, and specifically evaluating an integral scale of turbulence. To do so, an automatic traverse system is mounted at the exit of the CS and equipped to perform Hot Wire Anemometry (HWA) measurements. In this paper, two-point correlations are computed from the time signal of the axial velocity giving access to an evaluation of the turbulence timescales at each measurement point. For assessment of the advanced numerical method that is Large Eddy Simulation (LES), the same methodology is applied to a LES prediction of the CS. Although comparisons seem relevant and easily accessible, both approaches and contexts have fundamental differences: mostly in terms of duration of the signals acquired experimentally and numerically but also with potentially different acquisition frequencies. In the exercise that aims at comparing high-order statistics and diagnostics, the specificity of comparing experimental and numerical results is comprehensively discussed. Attention is given to the importance of the acquisition frequency, intrinsic bias of having a short duration signal and influence of the investigating windows. For an adequate evaluation of the turbulent time scales, it is found that comparing experiments and numerics for high Reynolds number flows inferring small-scale phenomena requires to obey a set of rules, otherwise important errors can be made. If adequately processed, LES and HWA are found to agree well indicating the potential of LES for such problems.
