    Boundary-Domain Integral Equations for Variable-Coefficient Mixed BVP in 2−Dimensional Unbounded Domain
    (Addis Ababa University, 2024-09) Eshetu Seid; Tsegaye Ayele
    In this thesis, the direct segregated Boundary Domain Integral Equations (BDIEs) for the Mixed Boundary Value Problems (MBVPs) for a scalar second-order elliptic Partial Differential Equation (PDE) with variable coefficients in an unbounded (exterior) 2D domain is considered. In this thesis, we formulate the exterior 2D domain of the direct segregated systems of BDIEs for the MBVPs for a scalar second-order divergent elliptic PDE with variable coefficients. The aim of this work is to reduce the MBVPs to some direct segregated BDIEs with the use of an appropriate parametrix (Levi function). We examine the characteristics of corresponding parametrix-based integral volume and layer potentials in some weighted Sobolev spaces, as well as the unique solvability of BDIEs and their equivalence to the original MBVPs. This analysis is based on the corresponding properties of the MBVPs in weighted Sobolev spaces that are proved as well.

    The Effect of Flexible Work Arrangements on Employee Performance: in the case of Commercial Bank of Ethiopia
    (A.A.U, 2025-06-15) Eshetu Seid; Habtamu Endris(PhD)
    This study investigates the effect of flexible work arrangements on employee performance at the Commercial Bank of Ethiopia. A quantitative research approach was employed, utilizing a questionnaire to collect data from 338 employees. The study examined five types of flexible work arrangements: telecommuting, condensed workweeks, flextime, part-time work, and shift work. Data analysis included descriptive statistics and multiple linear regression. The findings indicate that flextime, shift work, and condensed workweeks have a significant positive impact on employee performance. Flextime was found to be the strongest positive predictor. Contrary to expectations, telecommuting had a small but statistically significant negative effect on employee performance. Part-time work did not show a significant relationship with employee performance. The results suggest that the bank can enhance employee performance by strategically implementing flextime, shift work, and condensed workweeks. However, the negative effect of telecommuting warrants a review of its current policies and practices within the bank.
