Spatiotemporal patterns of bifacial and monofacial photovoltaic energy potential in an arid climate zone
...Show More Authors
Abstract<p>Climate change significantly affects photovoltaic (PV) energy potential in arid regions. This study quantifies climate change impacts on both monofacial and bifacial PV energy potential across Iraq using Community Climate System Model (CCSM4) projections under Representative Concentration Pathway (RCP) 4.5 and RCP8.5 scenarios spanning 2020–2100. Specific mathematical frameworks accounting for thermal and irradiance characteristics were applied across 18 representative regions covering Iraq’s diverse climatic zones, with bifacial systems modeled using dual-surface irradiance capture incorporating ground reflection and thermal dynamics. Results reveal distinct northwest–southeast gradient patterns in bifacial PV potential ranging from 0.267 to 0.302, with Western Anbar demonstrating exceptional climate resilience maintaining peak performance (0.291–0.302) under moderate scenarios, while northern provinces experience 2.5%–4% reductions under high-emission pathways. Under RCP8.5, 45% of Iraq’s territory falls below optimal deployment thresholds by century’s end. Bifacial systems consistently outperform monofacial technology by 19%–22% across all regions and scenarios, with enhanced relative advantages under extreme climate conditions. This represents the first comprehensive bifacial PV climate assessment for Iraq, providing critical evidence for renewable energy planning in climate-sensitive arid regions and supporting technology selection strategies for resilient solar infrastructure development.</p>

Study of the Halo Structure for Some Light Neutron-Rich Nuclei Using the Cosh Potential
...Show More Authors

The radial wave functions of the cosh potential within the three-body model of (Core+ 2n) have been employed to investigate the ground state properties such as the proton, neutron and matter densities and the associated rms radii of neutron-rich 6He, 11Li, 14Be, and 17B exotic nuclei. The density distributions of the core and two valence (halo) neutrons are described by the radial wave functions of the cosh potential. The obtained results provide the halo structure of the above exotic nuclei. Elastic electron scattering form factors of these halo nuclei are studied by the plane-wave Born approximation.

Deep clustering of Lagrangian trajectory for multi-task learning to energy saving in intelligent buildings using cooperative multi-agent
...Show More Authors

The intelligent buildings provided various incentives to get highly inefficient energy-saving caused by the non-stationary building environments. In the presence of such dynamic excitation with higher levels of nonlinearity and coupling effect of temperature and humidity, the HVAC system transitions from underdamped to overdamped indoor conditions. This led to the promotion of highly inefficient energy use and fluctuating indoor thermal comfort. To address these concerns, this study develops a novel framework based on deep clustering of lagrangian trajectories for multi-task learning (DCLTML) and adding a pre-cooling coil in the air handling unit (AHU) to alleviate a coupling issue. The proposed DCLTML exhibits great overall control and is

Reducing Energy Consumption in Iraqi Campuses with Passive Building Strategies: A Case Study at Al-Khwarizmi College of Engineering
...Show More Authors

University campuses in Iraq are substantial energy consumers, with consumption increasing significantly during periods of high temperatures, underscoring the necessity to enhance their energy performance. Energy simulation tools offer valuable insights into evaluating and improving the energy efficiency of buildings. This study focuses on simulating passive architectural design for three selected buildings at Al-Khwarizmi College of Engineering (AKCOE) to examine the effectiveness of their cooling systems. DesignBuilder software was employed, and climatic data for a year in Baghdad was collected to assess the influence of passive architectural strategies on the thermal performance of the targeted buildings. The simulations revealed that the

Evaluation of the Relationship between Osteoporosis and Body Fat Mass of the Upper and Lower Extremities by Dual-Energy X-Ray Absorptiometry
...Show More Authors

Background: Using dual-energy X-ray absorptiometry, body fat mass has been determined. The assessment of body fat mass was conducted utilizing dual-energy X-ray absorptiometry analysis of the pelvis and vertebral column. While it is acknowledged that osteoporosis can impact both body fat mass and bone mineral density, the particulars of this relationship currently remain uncertain. Objective: The aim of the present investigation is to assess gender differences in the effects of osteoporosis on the body fat mass of the upper and lower extremities. Method: 170 individuals participated (85 males and 85 females) in this study. Patients who presented with bone discomfort consisted of 40 males and 40 females. In addition, 90 apparently he

Theoretical Study of Photons Spectra around High Energy of Quark-antiquark Using QCD Theory
...Show More Authors

In this paper, we study and investigate the quark anti-quark interaction mechanism through the annihilation process. The production of photons in association with interaction quark and gluon in the annihilation process. We investigate the effect of critical temperature, strength coupling and photons energy in terms of the quantum chromodynamics model theory framework. We find that the use of large critical temperature Tc =134 allows us to dramatically increase the strength coupling of quarks interaction. Its sensitivity to decreasing in photons rate with respect to strength coupling estimates. We also discuss the effect of photons energy on the rate of the photon , such as energies in range (1.5 to 5 GeV).The photons rate increases
