Application of Bayesian network in risk assessment for website deployment scenarios

Abstract—The rapid development of web-based systems in the digital transformation era has led to a dramatic increase in the number and the severity of cyber-attacks. Current attack prevention solutions such as system monitoring, security testing and assessment are installed after the system has been deployed, thus requiring more cost and manpower. In that context, the need to assess cyber security risks before the deployment of web-based systems becomes increasingly urgent. This paper introduces a cyber security risk assessment mechanism for web-based systems before deployment. We use the Bayesian network to analyze and quantify the cyber security risks posed by threats to the deployment components of a website. First, the deployment components of potential website deployment scenarios are considered assets, so that their properties are mapped to specific vulnerabilities or threats. Next, the vulnerabilities or threats of each deployment component will be assessed according to the considered risk criteria in specific steps of a deployment process. The risk assessment results for deployment components are aggregated into the risk assessment results for their composed deployment scenario. Based on these results, administrators can compare and choose the least risky deployment scenario. Tóm tắt—Sự phát triển mạnh mẽ của các hệ thống trên nền tảng web trong công cuộc chuyển đổi số kéo theo sự gia tăng nhanh chóng về số lượng và mức độ nguy hiểm của các cuộc tấn công mạng. Các giải pháp phòng chống tấn công hiện nay như theo dõi hoạt động hệ thống, kiểm tra và đánh giá an toàn thông tin mạng được thực hiện khi hệ thống đã được triển khai, do đó đòi hỏi chi phí và nhân lực thực hiện lớn. Trong bối cảnh đó, nhu cầu đánh giá rủi ro an toàn thông tin mạng cho các hệ thống website trước khi triển khai thực tế trở nên cấp thiết. Bài báo này giới thiệu một cơ chế đánh giá rủi ro an toàn thông tin mạng cho các hệ thống website trước khi triển khai thực tế. Chúng tôi sử dụng mạng Bayes để phân tích và định lượng rủi ro về an toàn thông tin do các nguồn đe dọa khác nhau gây ra trên các thành phần triển khai của một website. Đầu tiên, các thành phần triển khai của các kịch bản triển khai website tiềm năng được mô hình hoá dưới dạng các tài sản, sao cho các thuộc tính của chúng đều được ánh xạ với các điểm yếu hoặc nguy cơ cụ thể. Tiếp đó, các điểm yếu, nguy cơ của từng thành phần triển khai sẽ được đánh giá theo các tiêu chí rủi ro đang xét tại mỗi thời điểm cụ thể trong quy trình triển khai. Kết quả đánh giá của các thành phần triển khai được tập hợp lại thành kết quả đánh giá hệ thống trong một kịch bản cụ thể. Căn cứ vào kết quả đánh giá rủi ro, người quản trị có thể so sánh các kịch bản triển khai tiềm năng với nhau để lựa chọn kịch bản triển khai ít rủi ro nhất.
Certificate-based Trust Establishment for Airplane Software Distribution

Contemporary developments in airplane manufacturing and maintenance are motivating the introduction of significant new IT infrastructure, supporting increased communication and data transfer among aircraft and a variety of ground-based information systems operated by airlines and their business partners. A next generation of airplane designs, incorporating wired and wireless network interfaces, will support a wide spectrum of ”eEnabled” or network-enabled applications, including distribution of airplane software, collection and off-board retrieval of airplane health reports, perhaps even participation in advanced collaborative air traffic control. In this context it is clear that airline business viability and even flight safety will come to depend on the security of data transported in these applications. Trust is a fundamental element of security and information assurance in any business context, and must be treated as such in the design of networked IT systems. We consider the establishment and maintenance of trust relations for an application typical of networkenabled airplane applications, namely an Airplane Assets Distribution System (AADS) which affords a capability for on-line distribution of airplane-resident software from suppliers via airlines to airplanes. The AADS involves a large number of parties, among whom explicit and manageable trust relations are essential. In order to achieve integrity and authenticity of software transmitted via the AADS, an infrastructure design solution employing digital signatures and public-key infrastructure must be instantiated and adapted for use in the aviation environment, which has its own architectural peculiarities and stringent assurance requirements. We introduce a protocol for initializing the certificate of an airplane which is used to secure and authenticate data sent by the airplane to its owning airline. We describe the basic protocol and several protection variants, first in an informal discussion and then in a precise formal way, pointing out the differences in security properties of the variants. Finally, we report on the results of model-checking our formalizations using the AVISPA protocol validation tool. The Airplane Certificate Initialization Protocol serves as a concrete example our methodology for modeling, analyzing, and discussing the design of safetyand securitycritical IT systems currently under development in the aerospace industry. Our experience shows this methodology is effective for exploring requirements and design alternatives, surfacing important issues, and giving evidence that the system architecture meets the desired security goals.
The Effect of Design Thinking Method Toward the Motivation of Visual Communication Design Students in Becoming an Entrepreneur

The world of work is a place of intense competition for each college graduate. Students are faced with developing new solutions to these problems/challenges so they need to practice identifying entrepreneurial opportunities so that the problem of the difficulty of competing in the world of work can be resolved with the emergence of new jobs. In the VCD department in the Visual Study subject using design thinking method as a study material in learning material with the aim of students being able to create a visual communication design that answers existing problems, so that ultimately students have a frame of mind in solving problems in running a business or facing client problems. Based on the results of data processing, the results show that there is a positive influence between design thinking methods on entrepreneurial motivation. Therefore, the role of design thinking methods in influencing student motivation to become entrepreneurs deserves further study.

Pinning Control of Complex Networked Systems: Synchronization, Consensus and Flocking of Networked Systems via Pinning

Synchronization, consensus and flocking are ubiquitous requirements in networked systems. Pinning Control of Complex Networked Systems investigates these requirements by using the pinning control strategy, which aims to control the whole dynamical network with huge numbers of nodes by imposing controllers for only a fraction of the nodes. As the direct control of every node in a dynamical network with huge numbers of nodes might be impossible or unnecessary, its then very important to use the pinning control strategy for the synchronization of complex dynamical networks. The research on pinning control strategy in consensus and flocking of multi-agent systems can not only help us to better understand the mechanisms of natural collective phenomena, but also benefit applications in mobile sensor/robot networks. This book offers a valuable resource for researchers and engineers working in the fields of control theory and control engineering.

Effects of Gaze Cues on Distributive Behavior of the Ultimatum Game in Adults With Attention Deficit Hyperactivity Disorder

Abstract Adults with attention deficit hyperactivity disorder (ADHD) have difficulty in social decision-making. The ultimatum game (UG) is a popular economic game used to evaluate social decision-making. This study aimed to examine the effects of schematically depicted eyes and ADHD symptoms on UG performance. Thirty adults with ADHD were recruited. The computer screen background was changed among the “eyespots,” “neutral,” and “flowers” conditions among 30 trials of UG. Through all trials, task performances were recorded, and then compared with 30 typical adults and 30 adults with autism spectrum disorder (ASD). The reaction time was not affected by the background in any group. Although typical adults distributed more money in the “eyespots” condition, a nonsignificant background effect was observed in adults with ADHD or ASD. These results may be associated with reduced attention to social cues in individuals with ADHD, and this ADHD characteristic might lead to difficulty in social decision-making.
Effect of Weight Self-Stigma and Self-Esteem on Aerobic Exercise Capacity in Adult Women with Different Body Compositions

Background: Overweight individuals face weight-related stigmatization, driving self-exclusion from exercise and physical activity. The extent to which weight self-stigma and self-esteem are associated with aerobic capacity remains unclear. Therefore, this study aimed to characterize the cardiopulmonary fitness, weight self-stigma, and self-esteem of overweight women and examine whether weight self-stigma and self-esteem predict cardiopulmonary aerobic capacity. Methods: A cross-sectional study was conducted with 66 women stratified into two groups: a normal weight (NW) group and an overweight (OW) group. The mean body mass indexes and ages of the NW and OW groups were 20.4 ± 0.36 kg/m2 and 29.5 ± 0.8 kg/m2, and 24 ± 7 years and 21 ± 3 years, respectively. Submaximal exercise testing using the modified Bruce treadmill protocol was conducted to measure the predicted oxygen uptake (VO2 peak) and energy expenditure. The Weight Self-Stigma Questionnaire and the Rosenberg Self-Esteem Scale were used. Results: Significantly lower mean of predicted VO2 peak and higher mean of energy expenditure were reported in the OW group compared with the NW group (25.8 ± 5.3 mL/kg/min vs. 28.7 ± 4.8 mL/kg/min, p = 0.001 and 9.7 ± 1.9 kcal/min vs. 7.5 ± 1.8 kcal, p = 0.03, respectively). There was a significant difference in weight self-stigma and self-esteem between the groups. Regression model analysis indicated that weight self-stigma and self-esteem explained 45% of the variance in the predicted VO2 peak. Conclusion: Strategies enhancing self-esteem and avoiding stigmatization should be embraced to promote fitness and engagement in physical activity among OW women.
An LES Insight Into Convective Mechanism of Heat Transfer in a Wall-Bounded Pin Matrix

We report on an LES (large-eddy-simulations) study of flow and heat transfer in a longitudinal periodic segment of a matrix of cylindrical rods in a staggered arrangement bounded by two parallel heated walls. The configuration replicates the set-up investigated experimentally by Ames et al. (ASME Turbo Expo, GT2007-27432) and mimics the situation encountered in internal cooling of gas-turbine blades. LES have been performed using the in-house finite-volume computational code T-FlowS. Considered are two Reynolds numbers, 10000 and 30000, based on the rod diameter and maximum velocity in the matrix. The unstructured grid contained around 5 and 15 million cells for the two Re numbers respectively. After validating the simulations with respect to the available experimental data, the paper discusses the characteristic vortex and plume structures, streamline and heatline patterns and their evolution along the pin matrix, around individual pins and at the pin-endwall junctions. It is concluded that the convection by organized vertical structures originated from vortex shedding govern the thermal field and play the key role in endwall heat transfer, exceeding by far the stochastic turbulent transport.Copyright © 2010 by ASME
Intelligent SERS Navigation System Guiding Brain Tumor Surgery by Intraoperatively Delineating the Metabolic Acidosis

Surgeons face challenges in intraoperatively defining margin of brain tumors due to its infiltrative nature. Extracellular acidosis caused by metabolic reprogramming of cancer cells is a reliable marker for tumor infiltrative regions. Although the acidic margin‐guided surgery shows promise in improving surgical prognosis, its clinical transition is delayed by having the exogenous probes approved by the drug supervision authority. Here, an intelligent surface‐enhanced Raman scattering (SERS) navigation system delineating glioma acidic margins without administration of exogenous probes is reported. With assistance of this system, the metabolites at the tumor cutting edges can be nondestructively transferred within a water droplet to a SERS chip with pH sensitivity. Homemade deep learning model automatically processes the Raman spectra collected from the SERS chip and delineates the pH map of tumor resection bed with increased speed. Acidity correlated cancer cell density and proliferation level are demonstrated in tumor cutting edges of animal models and excised tissues from glioma patients. The overall survival of animal models post the SERS system guided surgery is significantly increased in comparison to the conventional strategy used in clinical practice. This SERS system holds the promise in accelerating clinical transition of acidic margin‐guided surgery for solid tumors with infiltrative nature.
Simulation of MPPT Algorithm Based Hybrid Wind-Solar-Fuel Cell Energy System

This paper presents a new system configuration of the front-end rectifier stage for a hybrid wind/photovoltaic energy system. This configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. The inherent nature of this Cuk-SEPIC fused converter, additional input filters are not necessary to filter out high frequency harmonics. Harmonic content is detrimental for the generator lifespan, heating issues, and efficiency. The fused multiinput rectifier stage also allows Maximum Power Point Tracking (MPPT) to be used to extract maximum power from the wind and sun when it is available. An adaptive MPPT algorithm will be used for the wind system and a standard perturb and observe method will be used for the PV system. Operational analysis of the proposed system will be discussed in this paper. Simulation results are given to highlight the merits of the proposed circuit.
Machine Learning Assisted Troubleshooting Flows

An interactive troubleshooting flow (TF) directs customer care agents in diagnosing customer service issues and resolving these issues remotely. This step-by-step process, which helps agents triage issues and further investigate customers’ concerns, is dependent on the retrieval of customer telemetry data. A single TF document is a graph that an agent and customer traverse together. Each node or step in this graph is a question for the customer, an automated diagnostic test, or an action completed by the agent. The process has typically been based on rules and domain heuristics with a pre-defined path determined by the initial description of a customer’s concern. In this paper, we illustrate how a machine learning approach using available telemetry upfront or sufficiently early in the troubleshooting process, can speed up the time it takes to resolve the customer’s concern by better predicting the likelihood that an onsite technician will need to be dispatched to fully resolve the issue. We further demonstrate how cost-savings of such an approach could be assessed using model prediction outcomes, to help with model deployment decisions.
Memorable tourism experience in the context of astrotourism

ABSTRACT Astrotourism involves a variety of activities carried out during the night, requiring a deeper knowledge about the cognitive and emotional process that the tourist has and that leads to a memorable experience and loyalty. This study explores how (i) astrotourism stimuli are associated with cognitive states, designed by knowledge and involvement, (ii) cognitive states increase emotional states, represented by hedonism and refreshment, and (ii) emotional states generate responses, such as recommendation and loyalty. This study contributes to extending the S (stimulus) -O (organism) -R (response) framework by integrating cognitive appraisal theory and incorporating stimuli, cognitive and emotional states not used in the previous research. Recommendations for astrotourism destination managers are also discussed.
Rapid niche shifts as drivers for the spread of a non‐indigenous species under novel environmental conditions

Identifying niche shifts is key for forecasting future species distributions. Non‐indigenous species (NIS) are one of the greatest threats to biodiversity, and understanding how niche shifts affect the spread of NIS is fundamental. Here, we modelled the native and introduced niches, as well as the potential geographical extent of a widely distributed NIS, the Pacific oyster Magallana gigas. We then tested for niche shifts in environmental space and predicted spread under contemporary climate change (CCC) conditions.
Ground fault protection in ENEL distribuzione's experimental MV loop line

The paper describes the design and implementation of a new protection system consisting of a permissive overreach (PO) pilot relaying scheme with directional overcurrent relays for both phase and ground faults supporting closed-loop operation in MV network; attention is focused on ground fault relaying of loop networks operated with ungrounded or compensated neutral. Relevant zero-sequence quantities are studied and changes to relay settings are proposed and verified by detailed simulations. The system, developed within the framework of “Piano Operativo Interregionale” (POI) funded by Italian Government, will soon enter service in an Enel Distribuzione (hence:Enel-D) network.
Systematic illiquidity, characteristic illiquidity, and stock returns: Timeseries analysis

The objective of this research is to investigate the relationship between illiquidity and stock prices on the Tunisian stock exchange. While previous researches tended to focus on one form of illiquidity to examine this relationship, our study unifies three forms of illiquidity at the same time. Indeed, we simultaneously consider illiquidity as systematic risk, as a characteristic of the market, and as a characteristic of the stock. The aggregate illiquidity of the market is the average of individual stock illiquidity. The illiquidity risk is the sensitivity of the stock price to illiquidity shocks. Shocks of market illiquidity are estimated by the innovations in the expected market illiquidity. Results show that investors on the Tunisian stock exchange do not require higher returns when they expect a rise of market illiquidity, whereas investors on U.S markets are compensated for higher expected market illiquidity. In addition, shocks of market illiquidity provoke a fall in stock prices of small caps, while large caps are not sensitive to market illiquidity shocks. This differs slightly from results based on U.S. data where illiquidity shocks reduce all stock prices but most notably those of small caps. Robustness tests validate our findings. Our results are consistent with previous studies which reported that the “zero-return” ratio predicts significantly the return-illiquidity relationship on emerging markets.
Turbulent structures and characteristics of flows past a vertical surface-piercing finite circular cylinder

The flows past a vertical surface-piercing finite circular cylinder at Re1⁄4 2.7 10 and Fr1⁄4 1.1 are investigated numerically by means of delayed detached-eddy simulation and a geometric volume-of-fluid method based on piecewise-linear interface calculation. Good agreement with experimental data is achieved in various aspects, thereby demonstrating the reliability and accuracy of the present numerical model. On this basis, the characteristics of typical turbulent structures are analyzed thoroughly, as is the spanwise variation of the flow field caused by complex interactions. Because of the effects of the free surface and the free end, the velocity profile, separation angle, vorticity, and turbulent kinematic energy at different spanwise positions exhibit strong three-dimensionality, including the outward-spreading trend at the interface and the fluctuation induced by the upwash flow near the free end. By using the modified Omega–Liutex method ~ XR, instantaneous and time-averaged primary turbulent structures are identified well with the iso-surfaces of proper thresholds. A complete necklace vortex and a pair of wave-induced vortices are observed below the free surface, while a pair of large-scale arch vortices and two pairs of tip vortices are generated near the free end. The Liutex lines and streamlines are then used to analyze the spatial formations and developments of these structures. Furthermore, by performing spectral analysis at different probes on the cylinder surface and in the wake region, the dominant frequencies for each primary turbulent structure are determined.

Biocompatible and Antimicrobial Cellulose Acetate-Collagen Films Containing MWCNTs Decorated with TiO2 Nanoparticles for Potential Biomedical Applications

This research focuses on the synthesis of multi-walled carbon nanotubes (MWCNTs) decorated with TiO2 nanoparticles (NPs) and incorporated in cellulose acetate-collagen film in order to obtain a new biomaterial with potential biomedical applications and improved antimicrobial activity. The successful decoration of the MWCNTs with TiO2 NPs was confirmed by several structural and morphological analysis, such as Fourier transformed infrared spectroscopy, Raman spectroscopy, X-ray diffraction and transmission electron microscopy. The obtained nanocomposites were further incorporated into cellulose acetate-collagen films, at different concentrations and absorption kinetics, antimicrobial activity and in vitro biocompatibility of the obtained films was investigated. The antimicrobial tests sustained that the presence of the nanocomposites into the polymeric matrix is an important aspect in increasing and maintaining the antimicrobial activity of the polymeric wound dressings over time. The biocompatibility and cytotoxicity of the obtained films was evaluated using cellular viability/proliferation assay and fluorescent microscopy which revealed the ability of the obtained materials as potential wound dressing biomaterial.
Transmission zero controllable bandpass filters with dual and quad-band

Microstrip dual and quad-band bandpass filters with triangular stepped-impedance resonators are developed by using separate electric and magnetic coupling paths. Either the magnetic-dominant coupling or the electric-dominant coupling generates a transmission zero (TZ) but at different positions and the corresponding TZ can be controlled and adjusted by controlling the electric or magnetic coupling coefficient. Both the electric and the magnetic-dominant couplings generate a pair of TZs, but the additional coupling resonators are not required. The new designs have been demonstrated by measurement. Advantages of the new filters are not only their compact circuit topologies, miniature circuit sizes, independently controllable filter operation frequencies, but also their controllable TZs.
