A Probabilistic Approach to Maximize Cross-Selling Revenues of Financial Products

Yasin Altun, Ahmet Yucekaya — Sat, 24 Apr 2021 21:49:04 +0000

Customer oriented approach and developing analysis for customers have become more important as the competition became a global issue, especially after technological advancements. Companies aim to sell more products to new customers and also to their current customers while keeping them in the portfolio and making sure that they are happy. Cross-selling of products and services to their customers is almost as important as gaining new customers. In this paper, a probabilistic and integrated method of cross-selling financial products is proposed. The proposed method first segments the customers based on the selected criteria and then calculates the probability of buying each product using product and customer relationship matrixes. Then, the expected yield for each group of customers and offer is calculated, and the best cross-selling strategy is determined. The proposed methodology is applied to a Turkish bank that aims to sell financial products through cross-selling. The results show that the methodology successfully determines the product order to be used in cross-selling in an effort to increase the success rate in the selling process and expected revenue.

Minerals Dissolution Effect on the Mechanical Properties of Synthetic Carbonatic Rocks under a Reactive Fluid Injection

Sat, 24 Apr 2021 22:07:16 +0000

This research aims to evaluate the change in the stiffness and shear strength of synthetic carbonate rocks submitted to a reactive injection fluid. Therefore, laboratory tests were carried out with two types of cemented carbonatic rock artificially produced. The synthetic rocks were subjected to physical characterization tests (mineralogy, computed tomography, porosity, etc.) and mechanical characterization (uniaxial compressive strength and Brazilian tests) before and after the dissolution process to assess any changes in the samples. The dissolution test was performed in a modified oedometer cell, which allowed for measurements of horizontal displacements. The loading and dissolution phases were conducted using water and an acid solution to evaluate the influence of pH on their initial characteristics of the samples. The X-ray diffraction analysis revealed that the increase in maximum porosity by 57.8% and the increase in permeability were due to the dissolution of minerals. During dissolution, the horizontal stress increased linearly, and the maximum volumetric strain was 12.8%, owing to the loss of mass. This was also reflected in the mechanical characteristics since the samples lost about 72% of the strength after the dissolution with the acid solution. The study carried out in this paper helps explain and estimate changes on a micro-scale, that is, to understand how the dissolution of bonds between grains leads to macro-scale changes, such as the loss of mechanical strength causing irreversible damage to the rock.

Fatigue Life Assessment of 5083 “O” Aluminum Alloy Joints Welding by The MIG Process

Sat, 24 Apr 2021 22:12:27 +0000

In order to analyse the fatigue resistance of joints welded by the MIG process in aluminium alloy 5083 “O”, the present study analyses the influence of the shielding gases used during welding in the final strength of the product when it is subjected to fatigue stresses. The welds were made using two gas configurations, the first configuration being with 100% argon and the second with 75% argon and 25% helium. The results indicate that with the use of 25% helium compared to 100% argon it is possible to reduce the porosity present in the melted area of the joints and increase fatigue life for the conditions with cyclical loads of 80 and 60% of the maximum tension of the materials.

Impact of Self-Compassion on Existential Anxiety in Young Adults of Pakistan

It’s not much about the existential isolation but about our existential uniqueness, the feeling that no matter how deeply connected we are with someone, there is still an unbridgeable gap between every individual and all the elements of our perceived world which can’t be covered in any way possible. Young adulthood is an age where the self-creation process starts hence, the initiation of process of understanding life experiences, experimentation and exploration of meaning in life. All these processes comes with the consequences of overwhelming experiences of existential questioning, concern, and anxiety, leading to various other negative or positive psychological outcomes, depending upon the subjective experiences. Hence the current research was aimed to study the impact of self-compassion on existential anxiety in adolescents and young adults. The population consisted of both male and females (N=280). Current study is based on a quantitative correlation survey research design and the statistical analyses was done through SPSS (version 22). Neff’s Compassion Scale-Short Form (SCS-SF), and Existential anxiety questionnaire (EAQ) and Existential concern questionnaire (ECQ) scales were used. The statistical analysis involved Pearson product moment correlation, and Stepwise Regression. The finding of the study revealed that there was a significant weak negative relationship between Self-compassion and Existential Anxiety and a significant positive relationship between self-criticism and existential anxiety. Moreover, the isolation (subdomain of self-compassion) predicted 20.4% variance in level of Existential anxiety scale and 29.7% variance in Existential concern questionnaire. Following findings are significantly important regarding generating appropriate clinical interventions and provides beneficial insight into developing awareness programs on a community level.

Analysis Over the Accuracy of Dynamic Formulas for Predicting Ultimate Load Capacity in Deep Foundations

Tue, 04 May 2021 20:07:20 +0000

In Civil Engineering, particularly in Geotechnics, several empirical methods, commonly referred to as dynamic equations, have been proposed for prediction of ultimate load capacity of driven piles. However, these formulas are admitted inaccurate and, so, there is a need to evaluate the results obtained by them. In this work a comparative analysis of the values obtained by five dynamic equations (Janbu, Danish, Gates, FHWA-Gates and WSDOT) with actual ultimate load capacities (obtained through pile load tests at site) is made. Errors are measured using the root mean squared error and the correlation between the equation´s results and the measured values is verified. The results showed important differences between the ultimate capacities obtained from the analyzed models and the real values verified in field tests. It was also verified a superiority, in terms of lower error and greater correlation, of the WSDOT and Danish formulas. Attempts were made to improve the methods. For this, coefficients were determined that, when multiplied by the results of the formulas, promoted a reduction in error. Once again, WSDOT presented best perform in terms of correlation and error.
