A Reduced-Form Model for A Life Insurance’s Net Asset Value
Authors: MERIGUET AURORE , NDJENG-NDJENG ALEXANDRE , SALHI YAHIA , E.THEROND PIERRE
Published: December 2024

In this paper we develop a closed-form model for the net asset value of a life insurance portfolio aimed at simplifying the assessment and quantification of the impact of financial stress scenarios on the insurer’s solvency. In fact, using the current practice based on an internal model is timeconsuming and thus it is not relevant when it comes to carry out sensitivity studies that should require rapid action from the management. Due to the nature of the stress scenarios that are mostly related to the financial market determinants, their impact is quite straightforward on the market value of financial assets. Therefore, in this paper, we focus on the distortion caused on the liability side and investigate a reduced-form model for the best estimate liabilities that is not only easily interpretable but also capable of anticipating market variation impact in the liabilities. The model is built based on a dataset drawn from a French life insurer’s projection model using single, double and triple shocks on the interest rates yield curve, equity market value and profit sharing provision. In order to capture as much information as possible from the dataset, several feasible regression specifications are used. The general form of the empirical model is specified as a linear combination of the risk factors and its predictive ability is investigated based using an out-of sample analysis.
Do credit ratings affect European banks’ equity capital?
Authors: BEN HMIDEN OUSSAMA , BEN ZAIED YOUNES , BEN CHEIKH NIDHALEDDINE , BEN LAHOUEL BECHIR
Published: December 2024

This study investigates the impact of credit rating changes on banks’ equity capital following the 2008 financial crisis. Using data describing European commercial banks and a robust generalized method of moments estimation method, we find a negative association between equity capital and bank ratings. Investors may perceive a rating downgrade as a signal from rating agencies about a bank’s financial stability. We confirm empirically that riskier European  banks are forced to hold higher equity, and that market risk rather than regulatory constraints significantly increases banks’ equity capital.
HOW INSTITUTIONAL FRAMEWORK SHAPES BANK EFFICIENCY IN SUB-SAHARAN AFRICA
Authors: Arnaud TAMINI
Published: December 2024

We investigate whether the institutional framework influences bank ability to perform intermediation in Sub-Saharan Africa (SSA). Applying the stochastic frontier approach to a sample of SSA banks, we find that differences across institutional frameworks largely explain the differences in technical efficiency observed across SSA countries or regional organizations (UEMOA and CEMAC). Overall, the rule of law, the level of contract enforcement, and regulatory quality explain the observed heterogeneity. Reforms that promote the private sector and protect the rights of borrowers and lenders are therefore essential to improve the ability of SSA banks to supply credit.JEL Classification: G00; G21; G28; G32; F36; N27.
The Influence of Deep Drawing Parameters on Stresses and Strains in Drawing Tools in the Context of their Durability and Process Load
Authors: Kałduński Paweł
Published: December 2024

This publication presents the influence of selected parameters in the deep drawing process on the energy consumption of the entire process. It was analysed how die clearance and the radius of the rounded working edge of the die affect drawing force and work. Modifying these parameters does not directly affect the geometry of the finished stamped product. In addition, it was analysed how modifying the clearance and the radius of the rounding of the working edge of the die affects the magnitudes of stresses and strains in the tools, i.e. the punch and the die. The study was carried out numerically using Ansys Ls-Dyna software. An elastic-plastic model with isotropic hardening was used to model the tools without considering strain rate. This approach makes it possible to assess how a given process will affect the abrasive wear of the working surfaces of the die and punches when the yield stress in the tool material is exceeded. A significant increase in tool life was observed through a reduction in plastic deformation when using clearances greater than the thickness of the sheet metal. Using a larger die edge rounding radius also positively affected tool life, maximum drawing force, and total work.
Reuse of Treated Municipal Wastewater for the Production of Water for Agriculture
Authors: Szymański Kazimierz
Published: December 2024

Treated municipal wastewater may be a source of water that can be used for a wide range of industrial applications, municipal services, agriculture, and environmental protection. It must meet the criteria for environmental protection and human and animal health. Directive 2007/2/EC of the European Parliament and the Council covers the shared use of spatial information, including data sets on various issues in the field of environmental protection. The provisions of the above regulation on access to information and agreements mustn't constitute a separate legal system. Data provided by the Member States are necessary for the Commission to conduct monitoring. At present, it can be stated that the reuse of treated municipal wastewater reflects the state of scientific knowledge and international standards and practices of using treated wastewater for agricultural irrigation. Such policy promotes a circular economy, supports adaptation to climate change, and contributes to achieving the assumed objectives. Published Regulation (EU) 2020/741 of the European Parliament and of the Council of 25 May 2020 on minimum requirements for water reuse does not exclude food business operators from obtaining water quality parameters required to ensure compliance with the provisions of this regulation. New solutions for eliminating micropollutants from treated municipal wastewater will support these assumptions.

Criada há 33 anos, a Lei 8213/1991, conhecida como Lei de Cotas, que instituiu a obrigatoriedade das empresas com cem ou mais empregados reservem entre 2% e 5% das vagas para a contratação de pessoas com deficiência, a inclusão delas no trabalho ainda é um desafio para a sociedade brasileira. Para tentar entender os obstáculos que impedem maior avanço deste processo e o cenário atual brasileiro, foi realizada uma pesquisa qualitativa, onde foram encontradas como principais barreias: preconceito e discriminação; a relação familiar; o Benefício da Prestação Continuada; a baixa qualificação das pessoas com deficiência; a falta de acessibilidade; e o despreparo das empresas, associando, portanto, deficiência com incapacidade. Sendo assim, conclui-se que recorrer apenas à legislação não é algo suficiente para a inclusão no mercado de trabalho e que ainda faltam ações governamentais que implementem políticas públicas que auxiliem verdadeiramente este processo, além da participação efetiva de todos os segmentos da sociedade, pois uma sociedade bem-sucedida é aquela que promove em todos os âmbitos, o respeito à diversidade. Portanto, o referido trabalho, tem como objetivo analisar a situação de empregabilidade da Pessoa com Deficiência no Brasil, tornando-se relevante devido a responsabilidade social, ética e legal que o mercado de trabalho deve estabelecer em relação as pessoas com deficiência.

Design and Performance Evaluation of Conventional 6T vs. Single-Ended 6T SRAM Cell
Authors: M P Kavya , M G Nagaraj , P N Pavan kumar , N Sharath , N P Shashank
Published: December 2024

Abstract -As the demand for low-power, high-performance
memory systems grows, the design of efficient SRAM (Static
Random Access Memory) cells becomes increasingly crucial.
This paper explores the power consumption, performance, and
stability of two SRAM cell designs: the conventional 6T and
the Single Ended 6T SRAM. While the conventional 6T SRAM
is prone to read disturb noise and high leakage power, it
remains widely used due to its simplicity and compactness. To
address these issues, the Single Ended 6T SRAM cell is
introduced as an alternative, which reduces both power
consumption and area while maintaining competitive
performance. The study provides a detailed analysis of static
and dynamic power consumption, read/write stability, and
overall energy efficiency for both cell architectures. Simulation
results show that the Single Ended 6T SRAM offers significant
improvements in power reduction without compromising
speed, making it a promising solution for future low-power,
high-performance memory applications.
Keywords— SRAM cell, Pre-Charge Circuits, Sense

Attention deficit and hyperactivity and its relationship with learning difficulties among university students
Authors: Alsaied Mohamad Abdullah
Published: December 2024

Attention deficit combined with hyperactivity is considered one of the most significant challenges faced by children and adolescents in the educational environment. This condition is characterized by three main symptoms: difficulty in concentration, excessive movement, and impulsivity. These symptoms directly impact the student's ability to learn and comprehend, leading to multiple learning difficulties. Difficulty in concentration makes it challenging for the student to follow lessons, pay attention to details, and complete school tasks. The student may easily forget instructions or lose necessary items for assignments and activities. Excessive movement is manifested in the inability to sit quietly, constant fidgeting, and wandering around the classroom without a clear reason. This behavior can distract others and hinder the collective learning process. Impulsivity is evident in acting without thinking, interrupting others, and having difficulty waiting for one's turn. The student may talk excessively or answer questions before they are fully posed. These behaviors negatively affect relationships with teachers and peers, leading to social and psychological challenges. The relationship between attention deficit, hyperactivity, and learning difficulties is strong and interconnected. Students experiencing these symptoms are more susceptible to issues such as dyslexia, dysgraphia, and dyscalculia. These difficulties exacerbate the challenges faced by the student, potentially leading to decreased self-confidence and feelings of frustration. Early intervention and accurate diagnosis play a crucial role in assisting these students. This includes collaboration between parents, teachers, and specialists to develop individualized educational plans that cater to the student's needs. Effective educational strategies include providing a supportive learning environment, using multi-sensory teaching methods, and offering clear and specific instructions. Psychological support and behavioral therapy may be necessary to enhance self-regulation skills and social adaptation. Additionally, community awareness and education about this condition help reduce the social stigma associated with it, enabling students to receive the necessary support. Through joint efforts and understanding, students suffering from attention deficit and hyperactivity can be empowered to achieve their academic and personal potential, overcoming the challenges they face in their educational journey.

A mechanically stabilized earth wall design in a high seismic region (Türkiye)
Authors: Demirel Deliktas Ceren , Onur Ustaoglu Abdullah , Gokceoglu Candan
Published: December 2024

This paper presents the performance assessment of a mechanically stabilized earth (MSE) wall in highly seismic region in Türkiye. Wall performance under static and seismic conditions was searched with finite element and limit equilibrium analysis. Performance results of static case were compared with the lateral displacement limitations stipulated by some standards and specifications. On the other hand, lateral movement of wall after extreme seismic event was evaluated depending on post-earthquake investigation and shaking table testing due to the lack of deformation analysis-based regulations. The analyzed wall section in 23.95 m height is expected to experience no damage to moderate damage level without collapse with 2.1 cm for static case and 50.9 cm for an earthquake with the peak ground acceleration value of 0.533g. This case study shows that the performance of high single-tiered MSE walls is satisfactory even under high seismic actions.
Kinematic and block theory analysis in dolomitic rockmass for dam-site stability
Authors: Regmi Sanjeev , Kumar Dahal Ranjan
Published: December 2024

In the realm of dam-site slope stability assessments, an integrated approach utilizing both kinematic and block theory offers robust and comprehensive insights. While each theory possesses its own strengths and limitations, their combined application yields a more holistic understanding of potential failure mechanisms and enhances risk mitigation strategies. Kinematics analysis evaluates the potential movement of individual rock blocks within the rockmass, based on the orientation and properties of discontinuities whereas Block theory analyzes their stability under various loading conditions, like the weight of the dam and water pressure. This is the primary concern, ensuring the dam's slope which can withstand without failure or excessive deformations that could compromise its integrity. This study is concentrated on dolomitic rock type and hence considers the possible kartification dissolution, weathering and variable mechanical properties in such rock type. The geological model was prepared from geological study and six scan lines were drawn on each bank of Dam-site of Upper Tanahu Storage Hydroelectric Project. It was later verified with finite element analysis method. It was concluded that the maximum safe slope for dam-site slope is 50 degrees. There was slope deformation on the right bank of the Dam-site. Hence, slope excavation should be conducted after considering safe slope for gaining required slope stability of Headworks area.
Development of a medicane-induced landslide inventory; case study of 2023 Cyclone Daniel, Central Greece
Authors: Valkaniotis Sotiris , Taftsoglou Maria , Papathanasiou George , Samara Domna , Zei Caterina , Chatzitheodosiou Themistoklis
Published: December 2024

Cyclone (medicane) Daniel was a devastating Mediterranean tropical-like cyclone that affected Greece during September 4-8 2023. Severe rainfall in central and southern Greece led to widespread landslides and flooding that caused more than 2 billions in damages. Flooding in Thessaly region surpassed 800,000 hectares, the largest recorded flood event in recent history. The area most affected by landslides and debris flows was the mountainous part of Western Thessaly, along Pindos mountain range, where severe mass wasting was also documented during Medicane Ianos in September 2020.
Using post-event satellite imagery (WorldView, Planet and Copernicus Sentinel-2), and field surveys a detailed inventory of more than 3,000 landslides was recorded within an area of 2,7000 km2. Numerous damaging debris flows and debris floods were also mapped along most of the major rivers and streams of this area. Most landslides were shallow landslides of few meters up to 20-30 meters, but also a major number of large (up to 0.2 km2) earth and rock slides were also mapped. The largest rock slide (Pirra landslide), documented in detail by a field and UAS survey, occurred at the ridgeline above Pirra settlement, Trikala region. Pirra slide created a landslide dam that blocked a small ephemeral stream and led to the creation of a small ~7,000 m2 lake that persists seven months after the event. The detailed landslide inventory shows a narrow concentration that is interpreted to be related with the significant local variations of heavy rainfall, and also a strong correlation with either highly susceptible geological formations or prehistoric/inactive large/giant landslides. The Daniel landslide inventory (2023) is also compared with the inventory of Medicane Ianos (2020), as they have a similar distribution along the same area, and also have a significant overlap.

Published: December 2024

Acrocorinth is a steep rock 575m high that dominates the plain of the modern and ancient city of Corinth, in Greece. Today it is one of the most important archaeological sites in Greece, with a lot of visitors. The entrance area of the archaeological site is located at the entry point of the Castle, where for defensive reasons it was originally built in a position where it is particularly exposed to all kinds of natural hazards and rockfalls.
This paper analyzes the risks posed by rock falls (2) in the entrance area of the archaeological site, the footbridge and the visitor access road and examines the wider area which is an active geomorphological field, where rock falls have been occurring for centuries. The phenomenon of rocks and boulders falling from the steep slopes of Acrocorinthos is considered chronic, while evidence of rock falls already exists since ancient times.
In the context of the present research, due to the steep morphology, a drone with rtk and a high-definition camera was used to survey the high and steep slopes, in order to create a high-resolution 3D terrain model (3) that can clarify in detail the geometric characteristics of its discontinuities rock mass (1). The terrain model was created using ESRI's drone2map program, which is directly linked to ArcGISPro for further processing. After creating the high-resolution 3D model, the file was exported in point cloud format to determine the orientation and kinematics of the rock mass discontinuities. Then the kinetic energy of the potential rockfalls was analyzed using the 3D model and the wider area was demarcated into risk zones for rockfalls. Summarizing in the present work, the methodological approach for the creation of rockfall hazard zones using a digital terrain model is presented that could be widely used in corresponding cases.

Published: December 2024

This study aims to present a statistical analysis by using the newest data of intact strength and elastic parameters for Kiruna and Malmberget rock masses and examining their correlation with geological and alteration characteristics. In recent years, extensive geotechnical programs have been conducted in Kiruna and Malmberget mines to identify intact rock strength and elastic parameters for various rock masses. On one hand, crucial rock mass classification systems such as IRMR, RMR89 or Q rely on subjective assessment of the intact rock strength (IRS), or objectively through point load tests. On the other hand, accurate measurements of intact rock strength and elastic parameters are essential for a realistic estimation of in situ geotechnical conditions and stresses in deep mine designs. Ongoing UCS and TCS campaigns in both mines have yielded valuable information, contributing significantly to geotechnical models. Based on geotechnical borehole logging, face mapping and geotechnical laboratory testing, it is well-established through the previous years that Kiruna rock masses exhibit greater strength compared to Malmberget. This study’s findings add to the geotechnical knowledge base to show the intact rock strength of Malmberget rock types ranges from 100 to 300 MPa. In some instances, unaltered granite and trachyandesites exhibit strengths surpassing 300 MPa, whereas biotite schist and massive magnetite may exhibit intact strength below 90 MPa. In Kiruna rock types, a different scenario unfolds, showcasing a variation in intact strength between 180 and 400 MPa, including massive magnetite. The unaltered, strongest rock types in Kiruna such as porphyritic andesite-trachyandesite even exceed 500 MPa.

Application of YOLOv5s Algorithm for Real-Time Object Detection in Mobile Robot for Volcano Monitoring System
Authors: Evita Maria
Published: December 2024

Indonesia, a country with 172 volcanoes and second after Japan for the most eruption events, should monitor and predict the volcano eruption to prevent the effect of this natural disaster. Therefore, we have developed a 4-wheeled mobile robot equipped with monitoring sensors and a Logitech camera for this purpose. The robot should have the ability to detect objects in this extreme environment to avoid collision while moving and monitoring the volcano’s physical parameters. It has been designed a deep machine learning of YOLOv5s algorithm for two objects mostly found at volcanoes such as trees and stones. After the training steps (object identification; dataset downloading (Google Chrome Extension and Open Images v6); image labeling (LabeImg); augmentation process (blur and rotation)) had been carried out, the images of the object then trained in three model variation which resulted in: mAP_0.5 = 51.9%, mAP_0.5:0.95 = 28.6%, 58% of precision and 50% recall with 12 minutes and 33 seconds of training time for the first model (batch=16 and epochs=100); mAP_0.5 = 59.7%, mAP_0.5:0.95 = 36.3%, 74% of precision and 54% recall with 36 minutes and 4 seconds of training time for the second model (batch=16 and epochs=300); mAP_0.5 = 59.9%, mAP_0.5:0.95 = 37.6%, 80% of precision and 55% recall with one hour and 25 seconds of training time for the last one (batch=16 and epochs=500) as the best model of these variations. Furthermore, these results were displayed for all test images for the best model.
