A Self-organising Isolated Anomaly Detection Architecture for Large Scale Systems

Monitoring a system is the ability of collecting and analyzing relevant information provided by the monitored devices so as to be continuously aware of the system state. However, the ever growing complexity and scale of systems makes both real time monitoring and fault detection a quite tedious task. Thus the usually adopted option is to focus solely on a subset of information states, so as to provide coarse-grained indicators. As a consequence, detecting isolated failures or anomalies is a quite challenging issue. In this work, we propose to address this issue by pushing the monitoring task at the edge of the network. We present a peer-to-peer based architecture, which enables nodes to adaptively and efficiently self-organize according to their ''health'' indicators. By exploiting both temporal and spatial correlations that exist between a device and its vicinity, our approach guarantees that only isolated anomalies (an anomaly is isolated if it impacts solely a monitored device) are reported on the fly to the network operator. We show that the end-to-end detection process, i.e., from the local detection to the management operator reporting, requires a logarithmic number of messages in the size of the network.
Semantic Segmentation of Metoceanic Processes Using SAR Observations and Deep Learning

Through the Synthetic Aperture Radar (SAR) embarked on the satellites Sentinel-1A and Sentinel-1B of the Copernicus program, a large quantity of observations is routinely acquired over the oceans. A wide range of features from both oceanic (e.g., biological slicks, icebergs, etc.) and meteorologic origin (e.g., rain cells, wind streaks, etc.) are distinguishable on these acquisitions. This paper studies the semantic segmentation of ten metoceanic processes either in the context of a large quantity of image-level groundtruths (i.e., weakly-supervised framework) or of scarce pixel-level groundtruths (i.e., fully-supervised framework). Our main result is that a fully-supervised model outperforms any tested weakly-supervised algorithm. Adding more segmentation examples in the training set would further increase the precision of the predictions. Trained on 20 × 20 km imagettes acquired from the WV acquisition mode of the Sentinel-1 mission, the model is shown to generalize, under some assumptions, to wide-swath SAR data, which further extents its application domain to coastal areas.
The New on-Line Version of the Man-Systems Integration Standards (NASA-STD-3000)

Since 1987, the Man-Systems Integration Standards (MSIS) has been accepted as the definitive document for specifying the human interface requirements to be met when designing any type of hardware for use in manned space-flight. To date, all copies of the document, including two rather thorough revisions, have been created with a desk-top publisher, and distributed to customers in paper form. From the MSIS’s inception, there has been a continuous search for an efficient method to distribute the document to customers electronically. An SBIR project completed in FY97, and some further funded effort completed in FY98, have resulted in the development of an on-line system which presents the MSIS in a very customer friendly configuration. This new, hyper-text, multi-media software utilized by the MSIS Web-site is known as PHIDIAS. This on-line version includes all text and graphics from the MSIS, plus clips from the associated Living and Working in Space video. Numerous attributes of the Web-compatible version of PHIDIAS make it an ideal choice for placing the MSIS on line. PHIDIAS is easily adaptable to allow inputting of the source information, be it text, graphics, tables, charts, photos, or audio or video clips, in whatever format they may exist originally. On query from the Web-site visitor, PHIDIAS creates Web-pages “on the fly”, allowing outputs of exactly the information requested, and eliminating the wait for multiple screens of unneeded data to be downloaded.
Changes in Intra-to-Extra-Cellular Water Ratio and Bioelectrical Parameters from Day-Before to Day-Of Competition in Bodybuilders: A Pilot Study

The present study analyzed the effects from day-before to day-of bodybuilding competition on intracellular water (ICW), extracellular water (ECW), total body water (TBW), and bioimpedance analysis (BIA) parameters (resistance, R; reactance, Xc; and derived scores) in bodybuilding athletes. We assessed anthropometry and BIA (foot-to-hand; tetrapolar; 50 kHz) in 11 male bodybuilders (29 ± 4 year-old; 81 ± 8 kg; 172 ± 7 cm; 27 ± 2 kg/m2) both on the pre-competition day and on the contest day. Results revealed significant increases in ICW (31.6 ± 2.9 to 33.1 ± 2.8 L), with concomitant decreases in ECW (19.8 ± 1.8 to 17.2 ± 1.4 L) and TBW (51.4 ± 4.6 to 50.3 ± 4.2 L) from the day-before competition to contest day, which resulted in relatively large increases in the ICW/ECW ratio (1.60 ± 0.03 to 1.92 ± 0.01 L). Moreover, significant increases in R (391 ± 34 to 413 ± 33 ohm), Xc (64 ± 7 to 70 ± 6 ohm), and phase angle (9.3 ± 0.6 to 9.6 ± 0.7 degree) were observed between time periods. The phase angle scores reported on show-day of 9.6 and 11.2 appear to be the highest group mean and individual values observed in the literature to date. In conclusion, the strategies carried out on the final day of peak-week bodybuilding preparation lead to changes in BIA parameters and body water, with fluids shifting from the extra- to the intracellular compartment.
Employing Multi-Phase DG Sources as Active Power Filters, Using Fuzzy Logic Controller

By placing distributed generation power sources beside a big nonlinear load, these sources can be used as a power quality enhancer, while injecting some active power to the network. In this paper, a new scheme to use the distributed generation power source in both operation modes is presented. In this scheme, a fuzzy controller is added to adjust the optimal set point of inverter between compensating mode and maximum active power injection mode, which works based on the harmonic content of the nonlinear load. As the high order current harmonics can be easily rejected using passive filters, the DG is used to compensate the low order harmonics of the load current. Multilevel transformerless cascade inverters are preferred in such utilization, as they have more flexibility in current/voltage waveform. The proposed scheme is simulated in MATLAB/SIMULINK to evaluate the circuit performance. Then, a 1kw single phase prototype of the circuit is used for experimental evaluation of the paper. Both simulative and experimental results prove that such a circuit can inject a well-controlled current with desired harmonics and THD, while having a smaller switching frequency and better efficiency, related to previous 3-phase inverter schemes in the literature.
Building a Stereo-angle into strip-sensors for the ATLAS-Upgrade Inner-Tracker Endcaps

The Strips Endcap detector for the ATLAS Upgrade needs several sens or shapes, each of which is approximately a wedge shape like the current SCT. For the End cap to use a stave-like approach as proposed for the barrel, care is needed to desig n the shapes to avoid clashes and minimise gaps between them. This note gives the basic form ulae for one way of building up a petal. It allows for a stereo-angle to be built into the wa fer, and takes into account the maximum usable wafer size.

Simulation Based Method for Design and Application of Digital Control System

With increasing number of microprocessors and DSP use as a control system in power semiconductor converters, the new approaches for design of digital control system must be implemented. Designing a digital control system requires use of control to output transfer function. For new, frequency controlled resonant converters, like LLC converter, standard averaging methods cannot be applied for revealing the transfer function. Instead of that, new simulation based, numerical methods must be employed.
Cytotoxic Compounds from Alcyoniidae: An Overview of the Last 30 Years

The octocoral family Alcyoniidae represents a rich source of bioactive substances with intriguing and unique structural features. This review aims to provide an updated overview of the compounds isolated from Alcyoniidae and displaying potential cytotoxic activity. In order to allow a better comparison among the bioactive compounds, we focused on molecules evaluated in vitro by using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, by far the most widely used method to analyze cell proliferation and viability. Specifically, we surveyed the last thirty years of research, finding 153 papers reporting on 344 compounds with proven cytotoxicity. The data were organized in tables to provide a ranking of the most active compounds, to be exploited for the selection of the most promising candidates for further screening and pre-clinical evaluation as anti-cancer agents. Specifically, we found that (22S,24S)-24-methyl-22,25-epoxyfurost-5-ene-3β,20β-diol (16), 3β,11-dihydroxy-24-methylene-9,11-secocholestan-5-en-9-one (23), (24S)-ergostane-3β,5α,6β,25 tetraol (146), sinulerectadione (227), sinulerectol C (229), and cladieunicellin I (277) exhibited stronger cytotoxicity than their respective positive control and that their mechanism of action has not yet been further investigated.
Occipital Neuralgia May Be a Possible Limitation on the Utility of the Buffalo Treadmill Test for Concussion Assessments: 2 Case Reports

Abstract: Two female athletes presented to clinic following a head injury and exhibited signs of concussion. Both athletes experienced exacerbation of symptoms secondary to dysautonomia related to concussion injury on the Buffalo Concussion Treadmill Test (BCTT). On repeat evaluation, both athletes exhibited neck pain with symptoms immediately provoked by palpation of the occipital nerves. After a third occipital nerve block, both athletes had complete resolution of symptoms and subsequently tolerated BCTT to the maximum rate of perceived exertion with no provoked symptoms. The athletes were cleared for return to sport without issue. These cases indicate a potential limitation in the utility of the BCTT for determining the etiology and management of concussion and postconcussion syndrome.
Using Mathematical Statistics Ethically in Research in The Social Sciences and Humanities

a larger population; another is its fragmentation. Because of multiple legitimate criticisms during the last decades, the interpretivist researchers have developed a whole range of methods, and combinations of them, in order to improve the validity of their qualitative (e.g. phenomenological, ethnographic, comparative) research studies. Under the current pressure of neoliberalism, and thanks to the massive development of modern technologies and statistical software, it has become possible to process astounding amounts of meta-data; “data-mining” has become a major theme. The developed economies support extensive research samples with an unprecedented large scope of data, including meta-analyses and The aim of the authors is to consider some of the ethical challenges caused by the use of statistical methods for research in the humanities and social sciences (specifically education sciences). Statistics has the potential to be a useful tool in the research methodology of these sciences but, on the other hand, it can be abused and misused when the scientists are not aware of its limitations and pre-conditions. Most of the problems arise with deciding what to do to try to answer their questions and how to collect the data. How the data are collected affects how the data are analysed, and how the data will be analysed should affect how the data are collected. The authors will make an introduction to the topic by showing the tension in choosing either quantitative (statistical) or qualitative methodology for research in the human and social sciences over recent decades. Then they will present some ethical consequences of the misuse of mathematical statistics and emphasise the need for greater awareness and education about its correct use in the social sciences and humanities.
Basic Morphological, Thermal and Physicochemical Properties of Sewage Sludge for Its Sustainable Energy and Material Use in the Circular Economy

The treated sewage sludge is a smart material that provides sustainable use of energy and material that can be adapted to the needs of modern human life. Pyrolysis is one of the waste recovery operation that enables the generation of various useful groups of substances from treated sludge, which can then be utilized separately by final energy and material recovery processes: (i) solid residue (pyrogenic material), (ii) liquid fraction (bio-oil), and (iii) non-condensable gas. Those fractions are the basis for fertilizers and alternative fuel or new chemicals production. The chapter combines data on the quality of treated sludge as a case study of an urban wastewater treatment plant (UWWTP) with the capacity of 360,000 population equivalents (PE). The analytical results of dried anaerobically treated sludge over a 10-year period (from 2010 to 2020) are evaluated with respect to the limit values from directives, resolutions, guidelines, and national legislation related to specific processing procedures and quality of the final product. The data provide a comprehensive insight into the basic properties of treated sludge and allow thoughtful use of this smart material for WtE processes, organic matter material conversion, and agricultural use in terms of protecting the environment and human health.
Insights into the Relationships between Morphological Traits of Larrea divaricata and Climate Variables in Southern South America

Premise of research. How vegetation adapts to environmental changes is one of the most important questions in plant science. Temperature and precipitation are considered the main climatic drivers of morphological variations in vegetation. Several studies have demonstrated that leaf morphology varies reliably with increasing latitude, and this is mostly attributed to changes in temperature and precipitation patterns. The morphological responses of plants to temperature and rainfall regimes in arid lands are still scarcely known and understood. We analyze the morphological variation in leaf traits (size and shape) as well as the internode distance in the species Larrea divaricata and their relationship with bioclimatic variables along a latitudinal gradient in central western Argentina. Methodology. We combined a set of morphological features and bioclimatic indexes using multivariate statistics and detected six relevant regions with clear differences in both plant morphology and climatic variables. Pivotal results. The largest foliar areas were located in sites with higher seasonal precipitation. Leaf shape was influenced by temperature, and the internode distances were larger under semihumid conditions. Conclusions. The plant traits of L. divaricata were influenced by the latitudinal gradient and the predominant climate conditions of each recognized region. The study of foliar morphology allowed us to identify environmental factors that potentially influenced morphological responses in the studied species. As a preliminary stage in our research, our contribution attempts to recognize woody plant adaptations to climate influence. Other environmental variables must be included in future work for a more complete analysis.
Unfair Treatment by the Police and Race: Is Religiosity a Protective Resource for Well-Being

A growing body of work documents the relationship between criminal justice and health has emerged in recent years, including the association between unfair treatment by the police (UTBP) and violent/racialized policing and health outcomes. However, little is known about the resources that could reduce the harmful consequences to well-being of UTBP. Using data from the Nashville Stress and Health Study, we consider both depressive symptoms and allostatic load (a physiological marker of health) and several dimensions of religiosity as stress buffers. African Americans (but not Whites) who experienced personal police contact reported higher depressive symptoms relative to those who experienced no police contact and those reporting vicarious UTBP. Weekly religious attendance and higher church-based support (but not beliefs in divine control, a causal attribution of God’s influence in daily life) mitigated this relationship. African Americans with personal UTBP had higher allostatic load than those with no UTBP. Neither church attendance nor church-based social support attenuated the relationship between personal UTBP and allostatic load, nor did divine control. We discuss how the results of our study can help clarify the parameters of the effectiveness of religious/spiritual coping for African Americans and their implications for criminal justice reform.
Predicting the hourly Hong Kong representative sky from Typical Meteorological Year data for dynamic daylighting simulation

This paper proposes a method to predict the hourly Hong Kong representative sky from Typical Meteorological Year data. An evaluation of the sensitivity of the vertical sky component demonstrates that the Hong Kong representative sky can provide better results than the Perez all-weather sky model. Error reductions of 9–23% can be expected in the four cardinal directions. To predict the Hong Kong representative sky from the Typical Meteorological Year data, a clear sky index can be derived from global horizontal irradiance. Three Hong Kong representative skies can be classified by the clear sky index corresponding to skies 1, 8 and 13 of the Hong Kong representative sky, respectively. The predicted hourly Hong Kong representative sky can provide the sky luminance data for the dynamic simulation of buildings.
Analytical Modeling and Band-Structure Engineering of Resonant Tunneling Diode for Biased Terahertz Detector

A new strategy to significantly enhance the nonlinearity of double-barrier resonant tunneling diode (RTD) in the positive differential resistance region is theoretically proposed and experimentally demonstrated. An analytical model containing physical insight into the resonant tunneling process is established to bridge the nonlinearity of the current–voltage curve and the band-structure information of RTD. It intuitively shows that the intrinsic current responsivity of RTD as well as its nonlinearity can be greatly improved via band-structure engineering, as enhancing the resonant energy level of the well and reducing the current before the resonant tunneling process. The validation of the proposed model and the associated band-structure engineering strategy are verified by both device simulation and experiments. A RTD device with intrinsic current responsivity of 6.74 A/W is realized, while the peak-to-valley current ratio (PVCR) is also as large as 8.92. This method provides a new pathway to design high-performance terahertz (THz) detectors using double-barrier RTD and may share new perspective on the potential of RTD-based THz transceivers.
Fast or slow: applying life history strategies to responsible gambling adherence

ABSTRACT From the evolutionary perspective, life history (LH) strategies have been used to account for individual differences in behaviors and traits such as impulsivity, sensation seeking, and risk-taking propensity. The present study aimed to extend the application of LH strategies based on the psychometric approach to study individual differences in endorsing protective gambling beliefs and adopting responsible gambling (RG) behaviors. We conducted a telephone survey in Macao, China, and acquired a community-dwelling Chinese adult sample (N = 697) with the two-stage cluster random sampling method. Regression analyses showed that individuals with slower LH strategies displayed higher levels of protective gambling beliefs and RG behaviors. As hypothesized, protective gambling beliefs demonstrated a positive association with RG behaviors; furthermore, we found its partial mediating effect on the relationship between LH strategies and RG behaviors. Our findings suggested that one could take LH strategies into account in understanding individual differences in adopting RG behaviors and designing tailored measures to promote RG adherence. The present study also highlighted the effect of protective gambling beliefs in exploring the underlying mechanism of the link between LH strategies and RG behaviors, pointing to a potential avenue in fostering protective gambling beliefs to further increase RG adherence.
Lean production, information and communication technologies and operational performance

The main goal of the present research is to understand how the association between lean production and information and communication technologies (ICTs) (both internal- and external-oriented) impact on operational performance. A survey was conducted with data from 110 Brazilian manufacturers. The research constructs were validated through rigorous procedures (convergent and discriminant validity, and reliability), and hypotheses were tested using Ordinary Least Square regression. Our results indicate a mix of contradictory results, such as: (i) internal-oriented ICTs positively moderate the effect of lean on operational performance; and (ii) external-oriented ICTs negatively moderate the effect of lean on operational performance. These results evidence the importance of understanding the systemic relationships between lean and ICTs, both internally and externally, that were not tested before. As practical implications, findings suggest that managers should prioritise internal ICTs implementation if they intend to increase the impact of lean on operational performance.
From Tempests and Hydraulic Machines to the Arno Diversion: the Historical Significance of da Vinci's Study of Water

In his elaborate narration of the project to divert the Arno River, historian Roger D. Masters (1998) speculates about the collaboration between Leonardo da Vinci and Niccolo Machiavelli. However, Masters’s emphasis on the relationship between these two intellectuals is insignificant compared to what the Arno Project reveals about both the historical significance of water and da Vinci’s development through his study of water. The reemergence of classical thought and the importance of water in society led da Vinci to pursue multiple water-related projects. Da Vinci’s intellectual development from his study of water, manifested in sketches of tempests and hydraulic machines as well as the Arno Project, reveals his pivotal role in Renaissance society as well as in the development of the scientific method.
