Understanding Ethiopia’s Maritime Deal with Somaliland Through Abiy Ahmed’s Foreign Policy

This paper examines Ethiopia’s maritime deal with the de facto state of Somaliland in line with Abiy Ahmed’s foreign policy. A qualitative approach was employed, and secondary data sources obtained from the literature, such as books, journal articles, government and international organisation reports, newsletters, and other credible internet sources, were analysed through qualitative data analysis techniques. The study's findings can be summarised as follows: The study postulates that Ethiopia’s port deal with Somaliland raises regional tension in the Horn of Africa, a region often known for conflict and persistent instability. The deal also draws the contending interest of external forces. Turkey becomes the guardian of Somalia’s coastline, the UAE supports Ethiopia’s agreement with Somaliland, and Egypt provides direct military support to Somalia for the first time in four decades. This development contributes to the escalation of diplomatic strife between Ethiopia and Somalia and regional tensions. The study also examines Ethiopia’s post-2018 foreign policy since Abiy Ahmed took office. It underlines that Ethiopia remains without a clear foreign policy despite Abiy Ahmed’s attempt in his early tenure to revise the 2002 Foreign Affairs and National Security Policy and Strategy. The study asserts that the country’s foreign policy is significantly influenced by Abiy Ahmed’s highly personalised diplomacy and foreign relations that often bypass institutional approaches. In an assertion, the Ethiopian government was working to use multiple ports, including in Sudan, Eritrea, and Somalia, through port diversification policy. However, all the previous port diversification attempts were abandoned without a clear justification. In exchange, Abiy Ahmed signed a direct sea access maritime deal with Somaliland to recognise Somalia’s breakaway region. This development resulted in a suspicious attitude among Ethiopia’s neighbours, notably Eritrea and Somalia, who initiated a new tripartite bloc with Egypt. This has the potential to isolate Ethiopia in the Horn of Africa diplomatically

A Newly Developed Compressed Air Cannon Test Bench Designed for Multi-Impact Analysis of Composite Structures

Understanding the response and damage evolution of structures subjected to multiple impact events is essential for designing resilient structures capable of withstanding complex loading scenarios, such as impacts from hail, gravel or foreign object debris. This article presents the development and characterization of a novel test bench, the “Compressed air multi-cannon”, designed specifically for studying the multi-impact behavior of composite materials. This test bench offers advantages over traditional impact testing methods by enabling controlled and adjustable impact parameters, including number of impacts, spatial and temporal lag, energy, angle and impactor dimensions. The primary objective of this work is to provide a detailed description of the test bench design, construction, and validation procedures. Key components such as the pressurized air system, projectile launch mechanism, target mounting arrangement, and data acquisition system are discussed. Experimental methodologies for assessing multi-impact response, specimen preparation, instrumentation, and data analysis techniques are outlined. Through a series of single-impact and multi-impact tests, distinctive damage mechanisms and energy absorption characteristics were observed in composite structures, revealing significant differences in how composites respond under single- and multi-impact conditions. It was found that the single-impact configuration remains particularly critical compared to multi-impact configurations with a high number of impacts. However, further testing is required to determine whether this result holds true under varying impact parameters, highlighting the unique value of this machine for exploring new, realistic questions in the literature.
