Abstract:
The Hellenic Naval Academy (HNA) reports the latest results from a medium-range, near-maritime, free-space laser-communications-testing facility, between the lighthouse of Psitalia Island and the academy’s laboratory building. The FSO link is established within the premises of Piraeus port, with a path length of 2958 m and an average altitude of 35 m, mainly above water. Recently, the facility was upgraded through the addition of a BLS450 scintillometer, which is co-located with the MRV TS5000/155 FSO system and a WS-2000 weather station.

Abstract:
Studies on Physico-chemical properties of binary liquid mixtures provide information on the nature of interactions between the constituent of the binaries. Literature provides extensive data on the static dielectric constant (ε0) and refractive index (n) of liquid compounds, but the combined study of all is quite scarce. In the present work static dielectric constant (ε0) and refractive index (n) have been experimentally determined for binary liquid mixture of 1-Propanol (PrOH) with Acetophenone (ACP) over the entire concentration range of mixture composition (0.0 →1.0) at constant temperature

This paper presents a terahertz (THz) metamaterial absorber made of stainless steel. We found that the absorption rate of electromagnetic waves reached 99.95% at 1.563 THz. Later, we analyzed the effect of structural parameter changes on absorption. Finally, we explored the application of the absorber in refractive index sensing. We numerically demonstrated that when the refractive index (n) is changing from 1 to 1.05, our absorber can yield a sensitivity of 74.18 μm/refractive index unit (RIU), and the quality factor (Q-factor) of this sensor is 36.35.

Abstract:
The paper presents an algorithm for estimating atmospheric turbulence using a special optical target in the infrared wavelength range. A comparison is made of the structural function of the refractive index based on the data of the AMK-03 ultrasonic weather station and the data obtained by processing the target images. It is found that the values of the structural function of the refractive index obtained from the AMK-03 weather station and the passive optical method differ by three orders of magnitude along the route.

Abstract:
With the proliferation of Free Trade Agreements (FTAs) over the past decade, demand for quantitative analysis of their likely impacts has surged. The main quantitative tool for performing such analysis is Computable General Equilibrium (CGE) modeling. Yet these models have been widely criticized for performing poorly (Kehoe, 2002) and having weak econometric foundations (McKitrick, 1998; Jorgenson, 1984). FTA results have been shown to be particularly sensitive to the trade elasticities, with small trade elasticities generating large terms of trade effects and relatively modest efficiency gain

SEISMIC FRAGILITY ANALYSIS OF STEEL FRAMES WITH FULLY-BOLTED CORE TUBE JOINTS. The Hong Kong Institute of Steel Construction, 2024. http://dx.doi.org/10.18057/ijasc.2024.20.3.1.

Abstract:
In this paper, the joint parameters derived from testing the new fully-bolted core tube beam-column joint were utilized in the finite element analysis of the complete frame structure. The static elastic-plastic time-history analysis of 8, 12, 16, and 20-story steel frames with the braces was carried out. By comparing the maximum inter-layer displacement angles in the X and Y directions when the frame yielded, the rationality of the brace arrangement and the applicability of the new fully-bolted core tube beam-column joints in the multi-story and high-rise steel frames were confirmed.
