: The hospital is one type of land use utilization which could cause vehicle attraction. It is estimated that the existence of the new Ar-Rozy Hospital would become a trip attraction. For this reason, it is necessary to conduct research to anticipate the magnitude of the movement attraction which would occur in the future due to the existence of the new Ar-Rozy Hospital. This study uses trip generation analysis at 3 existing hospitals located around downtown Probolinggo. The primary data used is a survey of vehicles entering and leaving the hospital, and the secondary one is data consisting the number of polyclinics (X1) , practicing doctors (X2) , medical staff (X3) , land area (X4) , rooms (X5) , beds (X6) . The result shows that all independent variables affect the occurrence of vehicle attraction. The best model suitable for representing the conditions of the hospital vehicle attraction is chosen based on the results of a significant regression model and consideration of the highest R 2 , the best model is : Y = 174,256 + (-14,735) Number of Polyclinics (X1) + (13,081) Practicing Doctor (X2) . R 2 = 0.940.

: This paper presents a numerical parametric study of Concrete Encased Steel Column (CESC) due to centrically and eccentrically axial load. To model the confining pressure of rebar and steel profile, modified Mander’s equations were used. The non-linear sectional analysis was performed using the fiber-based method. The CESC section was discretized using Netgen 2D meshing algorithm. The developed CESC model was validated using the available test results in the literature. After the model was validated, parametric studies were conducted to investigate the behaviors of CESC with different concrete compression strength, confinement bar diameter, and confining distance. The parametric studies found that the columns with higher concrete compression strength tend to have higher axial and flexural capacity but reduce the overall ductility. Increasing the confinement bar diameter slightly increases the axial and flexural capacity and ductility. On the other hand, utilizing tighter confinement space resulted in higher ductility but with insignificant increase in axial and flexural capacity.

The process of icing involves the freezing of overflow layers, on ground or within streams, and results in ice bodies called “aufeis” that are common in most northern landscapes. Knowledge about aufeis is still limited despite the cold region engineering challenge they represent. Understanding the causes of overflow events leading to aufeis development represents a key for the prediction, mitigation, and management of this geohazard, and can also support the planning and design of infrastructure in the North. This paper introduces a practical classification for the diverse range of overflow processes that generate aufeis, including underrepresented processes, such as the instability of winter streamflow. Importantly, it distinguishes flow conveyance from water supply overflow processes and describes the temporal aspect of icing intensity. Finally, research topics are proposed to improve our understanding of aufeis, including their predictability, the impact of climate change on their occurrence and extent, and stream morphology-aufeis interaction.

Artificial intelligence technology is now regarded as one of the most significant innovations, aiding humans in finding solutions to a wide range of problems. Because to inventions with such cutting-edge and exceptional features, this field is receiving a lot of attention from all around the world. In this study, the hybrid model adaptive selection slime mould algorithm (ASSMA) is applied to address the project’s multi-objective time, cost, quality, and environment trade-off problem. ASSMA is contrasted with previous algorithms such as multiple-objective swarm algorithm, the opposition-based multi-objective development algorithm, and the slime mould algorithm to emphasize the outcomes of the proposed model. Using performance parameters that evaluate model quality, it is anticipated that this study will greatly outperform and expand upon previous models.
