Wave Effects on the Initial Dilution of Untreated Wastewater Discharge for Santa Marta’s Submarine Outfall (Colombia)
Authors: García-Rentería Francisco-Fernando , Chang Nieto Gustavo Ariel , Cortés Gustavo Hernández
Published: February 2023

The initial dilution generated by the final disposal of untreated wastewater through a submarine outfall in Santa Marta was examined with a near-field dilution model. Northward and eastward seawater velocity, salinity, and temperature profiles from a 3D hydrodynamic model were used to provide the oceanic conditions to calculate the dilution. The upwelling phenomenon occurs two times a year at the wastewater discharge site, the major from December to March and the minor in July, eliminating the stratification condition of seawater. The results of the dilution model showed that in these periods the plume reaches the water surface, achieving dilutions greater than 100. In addition, the external wave effect on the initial dilution of submarine outfall discharge in Santa Marta was determined. Surface waves increase dilution during the dry period of the year, when trade winds increase the surge and start the upwelling phenomenon. The dilution with/without waves factor is up to 1.90 for the center of the plume on the water column.
Real-Time Simulation of Hydraulic Fracturing Using a Combined Integrated Finite Difference and Discontinuous Displacement Method: Numerical Algorithm and Field Applications
Authors: Wang Shihao , Yu Xiangyu , Winterfeld Philip H. , Wu Yu-Shu
Published: February 2023

Real-time simulation of hydraulic fracturing operations is of critical importance to the field-scale stimulation applications. In this paper, we present an efficient yet reasonably accurate program for the numerical modeling of dynamic fractures. Our program, named as FracCSM, is based on combined Integrated Finite Difference (IFD) method and Discontinuous Displacement Method (DDM). FracCSM simulates the initiation and propagation of hydraulic fractures with DDM and mass/heat transport inside fractures by IFD. The frictional loss within the wellbore is also taken into consideration. In this way, we are able to model the propped height and length of the fractures subject to the stress interference effect. Moreover, FracCSM captures the stress shadow effect of multi-stage fractures. To facilitate the monitoring and decision making during the hydraulic fracturing process, we have developed a general framework that supports real-time simulation of fracture propagation. Our developed program demonstrates sound accuracy in comparison with existing simulators. The novelty of this work is the combined simulation algorithm to simulate the multiphysical process during hydraulic fracturing operations. We will demonstrate the program structure as well as the field applications of FracCSM to the real-time simulation of hydraulic fracturing operations in Sulige tight sandstone reservoir.

THE MEANING OF PROBABILITY FROM A FOUNDATIONAL PERSPECTIVE
Authors: Borovcnik Manfred
Published: February 2023

We focus on the ways in which we can use a frequentist interpretation of probability to develop suitable methods for statistical inference. The discussion about the controversy in the foundations reveals that a frequentist conception is highly prone to dispute, as a justification of it fails from a rational perspective when the explication of probability integrates statistical inference. We give an overview on the dispute and the crucial examples that highlight the deficiencies of a purely frequentist position towards probability. The concept of probability emerges from a mixture of meanings. A shift in connotation of probability towards a biased frequentist meaning decreases the scope of probability or the quality of applications. Probability is a complementary concept, which falls apart if we reduce it to one view. This gives rise to investigate approaches towards teaching from a wider perspective on the range of meanings of probability apart from frequentist aspects. Empirical studies show the shortcomings of educational approaches that ignore subjectivist aspects of probability, which leads to far-reaching misconceptions not only about the use of Bayes’ formula but also in the perception of probabilities at large.

Na sequência, detalhamos aspectos importantes do livro de Courant para, por fim, traçarmos um paralelo entre as obras.  Através desta investigação, foi possível apontarmos aspectos desta disciplina que podem ser trabalhados de modo distinto, explorando outras formas interpretativas, com releituras de alguns tópicos, de modo a expandir o olhar para assuntos que se mostraram essenciais para o desenvolvimento, e concepção atual, da própria matemática, conduzindo a implicações pedagógicas em relação ao ensino destes tópicos.
MODELAGEM MATEMÁTICA DA EVOLUÇÃO DA PANDEMIA DE COVID-19 NO BRASIL
Authors: Petry Vitor José , Moreira Luiz Henrique
Published: February 2023

Em março de $2020$, a Organização Mundial da Saúde (OMS) declarou pandemia mundial da COVID-19. A tomada de decisões por autoridades em momentos de crise sanitária, como a causada pela COVID-19, requer ações na tentativa de restringir o contato entre indivíduos infectados e suscetíveis com o intuito de interromper ou diminuir o ciclo de contágio, porém, com atenção aos impactos dessas medidas nas sociedades afetadas, principalmente nos setores produtivos e da educação. A modelagem matemática com modelos da epidemiologia permite fazer simulações de diferentes cenários, constituindo-se como uma das ferramentas que podem auxiliar os gestores na tomada de decisões, permitindo uma análise mais equilibrada e embasada sobre os possíveis impactos de suas decisões sobre a epidemia. Neste trabalho, foi feita uma adaptação dos modelos SIR e SIRS, que descrevem a dinâmica entre indivíduos suscetíveis, infectados e removidos, com a finalidade de simular o desenvolvimento da pandemia no Brasil. Ao resolver o problema inverso foram ajustadas funções para modelar as taxas de transmissão e de letalidade de acordo com o modelo adaptado, tendo como parâmetro de comparação os dados oficiais de casos e de óbitos disponibilizados pelo Ministério da Saúde. Nas simulações realizadas observou-se a influência dessas taxas nas curvas de contágio e de óbitos. Uma das adaptações feitas no modelo permite considerar os efeitos da imunização da população. A análise destes efeitos é um dos resultados mais expressivos observados nas simulações, sugerindo-se que com seu avanço, foi possível flexibilizar regras de isolamento social com o retorno de atividades econômicas, sociais e de ensino, sem a retomada significativa do crescimento das curvas de contágio e, principalmente, de óbitos, dentro do período analisado.
Development and Analysis of a Reconnaissance-Technique Knowledge Graph
Authors: Heverin Thomas , Deitz Elsa , Cohen Eve , Wilkes Jordana
Published: February 2023

Penetration testing involves the use of many tools and techniques. The first stage of penetration testing involves conducting reconnaissance on a target organization. In the reconnaissance phase, adversaries use tools to find network data, people data, company/organization data, and attack data to generate a risk assessment about a target to determine where initial weaknesses may be. Although a small number of tools can be used to conduct many of reconnaissance tasks, including Shodan, Nmap, Recon-ng, Maltego, Metasploit, Google and more, each tool holds an abundance of specific techniques that can be used. Furthermore, each technique uses unique syntax. For example, Nmap holds over 600 scripts that make up its Nmap Scripting Engine. Depending on the type of device targeted, Nmap scripts can scan for ports, operating systems, IP addresses, hostnames and more. As another example, Maltego operates over 150 transforms or modules that collect data on organizations, files and people.
Understanding which reconnaissance tool, techniques within those tools, and the syntax for each technique represents a highly complex task. MITRE ATT&CK, a widely accepted framework, models tactics and techniques within the tactics to help users make sense of adversarial behaviours. The tactic of reconnaissance is modelled in ATT&CK as well as its techniques. However, the explicit links between reconnaissance techniques are not modelled. Our research focused on the development of an ontology called Recontology to model the domain of reconnaissance. Recontology was then used to form Reconnaissance-Technique Graph (RT-Graph) to model 102 reconnaissance techniques and the directional links between the techniques. We used exploratory data analysis (EDA) methods including a graph spatial-layout algorithm and several graph-statistical algorithms to examine RT-Graph. We also used EDA to find critical techniques within the graph. Patterns across the results are discussed as well as implications for real-world uses of RT-Graph.
Using Deep Reinforcement Learning for Assessing the Consequences of Cyber Mitigation Techniques on Industrial Control Systems
Authors: Merz Terry , Morales Rosado Romarie
Published: February 2023

This paper discusses an in-progress study involving the use of deep reinforcement learning (DRL) to mitigate the effects of an advanced cyber-attack against industrial control systems (ICS).  The research is a qualitative, exploratory study which emerged as a gap during the execution of two rapid prototyping studies.  During these studies, cyber defensive procedures, known as “Mitigation, were characterized as actions taken to minimize the impact of ongoing advanced cyber-attacks against an ICS while enabling primary operations to continue.  To execute Mitigation procedures, affected ICS components required rapid isolation and quarantining from “healthy” system segments. However today, with most attacks leveraging automation, mitigation also requires rapid decision-making capabilities operating at the speed of automation yet with human-like refinement.  The authors settled on the choice of DRL as a viable solution to this problem due to the algorithm’s designs which involves “intelligent” decisions based upon continuous learning achieved through a rewards system.  The primary theory of this study posits that processes informed by data sources relative to the execution path of an advanced cyber-attack as well as the consequences of deploying a particular Mitigation procedure evolve the system into an ever-improving defensive capability.  This study seeks to produce a defensive DLR based software agent trained by a DRL based offensive software agent that generates policy refinements based upon extrapolations from a corrupted network state as reported by an IDS and baseline data. Results include an estimation rule that would quantify impacts of various mitigation actions while protecting the operational critical path and isolating an in-progress attack.  This study is in a conceptual phase and development has not started.

This research questions for this study are:

RQ1: Can this software agent categorize correctly an in-progress cyber-attack and extrapolate the potential ICS assets affected?

RQ2: Can this software agent categorize novel cyber-attacks and extrapolate a probable attack vector while enumerating affected assets?

RQ3: Can this software agent characterize how operations are affected by quarantine actions?

RQ4: Can this software agent generate a set of ranked recommended courses of action by effectiveness, and least negative effects on the operational critical path?
Managing Large-Scale Heterogeneous Deployments for Cybersecurity
Authors: Hurley JS Hurley
Published: February 2023

In cyber defense, we must contend with the massive amounts of data being generated in a variety of different formats and speeds. Unfortunately, traditional tools and methods are not meeting the requirements for scale and speed and rely too heavily on heuristics. Advancements in mobile technologies and the Internet of Things (IoTs) will continue to contribute to the additional growth in data volumes anticipated for the foreseeable future. As data continues to grow in complexity and scale, cyber professionals must rely upon models that are more elaborate and sophisticated to predict future behavior. More complex models can give additional inference capabilities; however, they are also difficult to scale and deploy in real-time environments. Managing large-scale, heterogeneous deployments for cybersecurity is challenging. Hardware capabilities and software tools both motivate and limit computational and inferential objectives. Hence, the interplay between data science (especially machine learning) and computation become more significant than ever to explore to gain more insight into heterogeneous deployments and how they can be more effectively managed. In this study, we identify ways in which data science tools and techniques can be used in improving the management of large-scale heterogeneous deployments for cybersecurity.
Risk likelihood of planned and unplanned cyber-attacks in small business sectors: A cybersecurity concern
Authors: Ncubukezi Tabisa
Published: February 2023

Human factors such as planned and unplanned cyber-attacks are a serious threat to any institution. The presence of planned and unplanned actions exposes the state of cybersecurity within the small business sector – leaving them vulnerable to a range of cyber-risks. This study used the AgenaRisk package with Bayesian Network (BN) tools to illustrate the likelihood of risk in planned and unplanned attacks. Adopting the package demonstrates the dependent and independent variables of the human factors, which are planned and unplanned, with their relationships resulting in the ultimate data breach. The work also combined qualitative research with quantitative risk analysis techniques to determine the risk likelihood of planned activities and unplanned employee actions and their behaviors influencing data breaches.

The work used the judgemental sampling method to select twenty-five (25) research participants who are business owners and Information Technology (IT) managers. An online survey was used to collect data from the selected research participants. Results were analysed using content analysis and interpreted using the package with BN tools, and risk analysis techniques. The results were further discussed, and the study concluded with remarks and future developments.
DACA: Automated Attack Scenarios and Dataset Generation
Authors: Korving Frank , Vaarandi Risto
Published: February 2023

Computer networks and systems are under an ever-increasing risk of being attacked and abused. High-quality datasets can assist with in-depth analysis of attack scenarios, improve detection rules, and help educate analysts. However, existing solutions for creating such datasets suffer from a number of drawbacks. First, several solutions are not open source with publicly released implementations or are not vendor neutral. Second, some existing solutions neglect the complexity and variance of specific attack techniques when creating datasets or neglect certain attack types. Third, existing solutions are not fully automating the entire data collection pipeline. This paper presents and discusses the Dataset Creation and Acquisition Engine (DACA), a configurable dataset generation testbed, built around commonly used Infrastructure-as-Code (IaC) and DevOps tooling which can be used to create varied, reproducible datasets in a highly automated fashion. DACA acts as a versatile wrapper around existing virtualization technologies and can be used by blue as well as red teamers alike to run attack scenarios and generate datasets. These in turn can be used for tuning detection rules, for educational purposes or pushed into data processing pipelines for further analysis. To show DACA's effectiveness, DACA is used to create two extensive datasets examining covert DNS Tunnelling activity on which a detailed analysis is performed.
Identifying Commonalities of Cyberattacks Against the Maritime Transportation System
Authors: Rohan Rebecca
Published: February 2023

The purpose of this study is to identify commonalities in cyberattacks against the civilian maritime transportation system (MTS). For this exploratory study, the researcher analysed documents to identify trends about the cyberattacks impacting and responsible adversaries targeting maritime operations. The MTS can use identified trends to make informed decisions about information technology (IT) and operational technology (OT) requiring new or enhanced cybersecurity measures. Current research examining publicly disclosed cyberattacks impacting MTS companies identifies the trend of increasing cyberattacks against the MTS. However, current research fails to examine adversaries and their social-political needs thoroughly. Knowledge of the adversary based on the Diamond Model of Intrusion Analysis can be augmented by identifying which MTS assets (e.g., shipbuilding, ports) and which aspect of the information security triad—Confidentiality, Integrity, or Availability (CIA)—the adversary targeted. At the conclusion of this limited, exploratory document analysis, the researcher determined the most compromised aspect of the information security triad was Availability and then Confidentiality; there were no identified Integrity compromises. The most targeted MTS assets was shipping companies, followed by ports, administration, shipbuilding, and vessels. Concerning the adversary customer behind MTS cyberattacks, China was first, followed by unknown cyber adversaries, then Russia, Iran, and Israel. Last, in terms of adversary’s social-political needs, data exfiltration occurred the most, followed by ransomware, political agenda, and unknown needs.
Categorizing Cyber Activity Through an Information-psychological and Information-technological Perspective, Case Ukraine.
Authors: Kantola Harry
Published: February 2023

Russian approach to warfighting includes an informational facet. Western hemisphere usually treats cyber activity as a tool similar to traditional warfighting tools such as rifles, artillery and tanks, whereas the Russian approach has an informational and narrative stance to the whole conflict. Placing information in the focus, switches the cyber activity to serve either an informational-psychological or an informational-technical approach. Examining the activity from this non-conventional trait and correlating it to other activities during the execution, the study highlights the coordination of kinetic and non-kinetic actions in an altered manner. In this article I am examining cyber activity through the terms of information-psychological and information-technological approach to form an understanding of Russian or Russian supported activities in cyber space before and during the Ukraine crisis. This will recognize types of cyber activity connected to actions in the physical environment. Actions identified are categorized and placed in a matrix created on psychological and/or technical clout. From this matrix groups of activities are scrutinized in correlation to other activities to expose possible narratives or underlying themes. The study relies on a variant of Grounded theory and is selected to elude from examine technical methods and actions. The observed timeframe is for the first study from 2021, well before the current hot phase, until summer 2022. This article is the first part of a two-stage study, where the first part examines cyber activity through the terms of information-psychological and information-technological approach. The second study places the previous findings in correlation to actions, reactions and mitigation activities to find out how defensive measures were relevant or if the outcome were result of something else than deliberate defensive (cyber-)activities. Throughout the larger study, the underlying hypothesis is that there is a larger coordination of cyber activities than acknowledged related to the ongoing crisis.
Predictors of Human Efficiency in Radar Detection Tasks
Authors: Fox Elizabeth , Stephenson Arielle , Stevens Christopher , Bowers Gregory
Published: February 2023

Aegis operators simultaneously locate and monitor the activity of several hostile targets, intervening and alerting their team when appropriate. Utilizing the Aegis Combat System, operators find, track, and respond to dynamic targets on a radar screen. The demand that operators undergo is often high, inevitably causing strain on cognitive functions and detriments to performance. We applied model-based measures, Cost and Multitasking Throughput, to quantify the influence of external factors on processing efficiency in radar task(s). We captured the influence of three experimental manipulations, each of three levels, on human efficiency to track the location of hostiles and/or detect brief radar interference. We collected participants’ performance to complete a multiple object tracking (MOT) task and an electronic attack detection task (EA) using a radar display. A factorial manipulation of conditions comprised changes to task(s) (EA, MOT, or both), the number of targets to track (2, 4, or 6) and the presence or absence of distractors, deemed 'friendlies' (between 500-1000 total tracks). Our novel individual- and model-based approach provided quantitative estimates of human efficiency. We compared the observed variation in efficiency among predictors including target quantity, visual load, and the presence of one or two interrelated tasks. Through quantifying the relationship of these variables to radar detection tasks, we discuss implications of our findings and provide a framework to examine how system designers may develop tools to alleviate observed cognitive demands and/or counter potential threats of electronic attacks in radar detection and tracking tasks.
On the Use and Strategic Implications of Cyber Ranges in Military Contexts: A Dual Typology
Authors: Andrew Dwyer  , Kathrin Moog  , Jantje Silomon  , Mischa Hansel
Published: February 2023

The use of simulated environments in cybersecurity – cyber ranges (CRs) – has become a popular method and tool to support training and education, assess system vulnerabilities, as well as to test and probe computer networks. Yet, CRs can be adopted to improve and enhance adversarial skill sets, tools, and operations that are attractive for military applications. This paper develops a strategic typology on how CRs have been used and adopted in military contexts (CRiMCs), where states have turned to CRs as one method to build cyber capacity, address proportionality and responsibility of cyber operations, as well as offer training and education.

We identify CRiMCs that offer two strategic purposes: 1) reserved for sovereign use and capability development and 2) those intended to support cyber capacity building through domestic resilience and collaborative inter-state exercises. We thus ask, why do states establish sovereign cyber ranges ‘on top’ of being involved in collaborative ones? Why and how do they differ? To answer such questions, this paper delves into both the crucial technical components that support each CRiMC type and their implications by offering exemplars from five states (Lithuania, Norway, Slovenia, the Netherlands, and the USA). The paper concludes with some preliminary thoughts on future research avenues on CRiMCs and their implications for the use and governance of state cyber capabilities.
A Quantitative Risk Assessment Framework for the Cybersecurity of Networked Medical Devices
Authors: Van Devender Maureen , McDonald Jeffrey Todd
Published: February 2023

Medical devices are increasingly the source of cybersecurity exposure in healthcare organizations. Research and media reports demonstrate that the exploitation of cybersecurity vulnerabilities can have significant adverse impacts ranging from the exposure of sensitive and personally identifiable patient information to compromising the integrity and availability of clinical care. The results can include identity theft and negative health consequences, including loss of life. Assessing the risk posed by medical devices can provide healthcare organizations with information to prioritize mitigation efforts. However, producing accurate risk assessments in environments with both sparse historical data and a lack of validation regarding the accuracy of forecasts is particularly challenging.

We present a risk assessment framework for quantifying the risk posed by connected medical devices in trusted healthcare networks. Our framework is built upon prominent existing frameworks and guidance for general risk assessment and cybersecurity risk assessment. We add a method for quantifying risk, which to our knowledge is novel in the context of medical devices on trusted networks. The framework provides a structure for combining publicly available information along with expert elicitation about threats, vulnerabilities, and consequences. The goal is to provide healthcare organizations with actionable information for prioritizing and mitigating risks in medical devices.

As a means of transportation in the process of catching fish, ship must be owned by fishermen. The purpose of this study was to determine the durability of ship made of fiberglass material and to know when the ship run and stopped. This research was conducted for 4 months in a fishing laboratory assisted by 2 lecturers and 3 students. Students were involved in order to gain knowledge and experience in making boats made of fiberglass. With an experimental methods, data collection was done by direct observation of the design process, material testing, durability, and stability of the ship at sea. The results of this research were obtained in terms of making boats, in which it had a quite long stage starting from knowing the place where the boat was used, designing, making, and testing it in the manufacture. Thus, it is necessary to be careful during the work in order to get better results. Based on the endurance and leak tests, the boat had good resistance and did not leak, so it could be further developed.

AbstractThe existence of alpheid shrimp species in Indonesia is not too much found in the latest scientific publications. Alpheid shrimp species can be used as an indicator to assess the quality of the environment in mangrove areas. The discovery of shrimp species from the Alpheid group adds to the list of biodiversity in the mangrove area of Kuala Langsa. Biodiversity of a high number of species in this group of shrimp is usually found in mangrove areas with muddy sand beaches. This is because, this type of shrimp has a habit of living in muddy areas. The living zone of this type of shrimp is almost the same location as the type of crab that is wrapped like the Scylla serrata group. Mangrove area kuala langsa although it has mangrove biodiversity that is relatively high. Kuala Langsa mangrove forests are dominated by the Rhizoporaceae group, which is a type of vegetation that is effective as a sediment trap from the direction of the river estuary while holding abrasion from the direction of the sea. In the current year there is also a condition of decrease in the number of large trees. This is caused by the harvest of mangrove wood to produce charcoal for fuel purposes. This condition will slowly make the function of the ecosystem decrease. Where the role of ecosystems provide living niches for aquatic organisms is decreasing. Land clearing of certain areas of the mangrove area for physical infrastructure purposes such as the construction of restaurants, settlements, roads, small aircraft runways, reduces the ability of the region to maintain the function of its ecosystem. The next thing is the ecological pressure for aquatic biota that has living niches in mangrove areas.Keyword: alpheid shrimp, alpheus, mangrove, ecosystem, kuala langsa, aceh

Informe Global Re|pensar las políticas para la creatividad
Authors: Saralegui Belén
Published: February 2023

Publicado en el 2022, el informe Global Re|pensar las políticas para la creatividad propone una mirada crítica de la producción y reproducción de bienes y servicios culturales. Una toma de postura de las políticas públicas en un sector históricamente relegado como es el de la cultura. En el último tiempo éste ha caído fuertemente en la desregulación de las nuevas vías de ejecución y creación, la carencia de normativa laboral y en la inequidad en la distribución de tareas; en definitiva, ha sido olvidado. La cultura posee, como bien lo indica el informe, el estatuto de bien público global. Pero, ¿qué sucede cuando aquellos bienes que constituyen la cultura dejan de ser públicos debido a la desregulación en las maneras de producir y reproducir, y dejan de ser globales porque sobreviven solo las más poderosas?
