Published: March 2021

Abstract
Visual object tracking is one of the challenging tasks in computer vision. Among tracking tasks, accurately state estimation is the main challenge. Most current methods simply adopt multi-scale searches or anchors to estimate the state, which need many hyper-parameters and complex calculations. To face this challenge, we propose an anchor-free tracking framework based on Siamese network. The proposed framework consists of template features guided Siamese subnetwork and keypoints detection subnetwork. We take simplified hourglass network as backbone in Siamese subnetwork to improve the tracking efficiency and the prediction of corners around target instead of the prediction of target in keypoints detection subnetwork. We experiment our approach on OTB-2015 and VOT-2016, and our approach acquire the best precision of 0.841 on OTB-2015 and runs at 39 FPS.

Published: March 2021

Abstract
Superposition of multiple index method is used to construct index-fusion remote sensing images, and color statistical analysis and color distance calculation are carried out for urban areas in the fusion remote sensing images to automatically extract the large-scale construction land. The evaluation of the accuracy of the automatically extracted construction land can be done by using high precision Google Earth images. Center of gravity of the automatically extracted construction land is taken as the measurement index of urban spatial distribution, and the dynamic changes of urban spatial structure are analyzed according to the center of gravity. Experiments show that this method can effectively distinguish construction land from other ground objects, thus realizing the high accuracy extraction of construction land. And the center of gravity of Honghu City shows a development pattern and its possible influencing factors for small cities in central China.

Authors: Kamil Ahmed T. , Saleh Hadeel M. , Abd-Alla Israa Hussain 
Published: March 2021

AbstractSeveral studies exist in the literature that utilized metaheuristics and nature-inspired algorithms to solve engineering problems. Particle Swarm Optimization (PSO) is a well-known nature-inspired algorithm that has been used for different optimization problems due to its simplicity and ability to find near-optimal solutions. However, PSO suffers from a problem of balancing between the global search and local search abilities when applied to engineering problems. Recently, a new variant of PSO based on a novel multi-swarm architecture called Multi-swarm Particle Swarm Optimization (MPSO) was proposed. The proposed MPSO was evaluated on solving normal and large-scale problems. This study evaluated the possibility of using MPSO to simulate Welded Beam Design (WDB) problem which is a mechanical engineering problem. Several simulations were performed using the proposed approach and from the results, MPSO model was observed to simulate WBD problem with better optimal solution compared to the standalone PSO. The outcome of this study further confirmed the robustness of the MPSO over the other known metaheuristics. Generally, MPSO achieved an excellent optimization performance with a fast convergence learning process.

Authors: Linda R , Prabowo H , Indrayadi I 
Published: March 2021

Abstract
Cementitious composites are common construction material for infrastructures. Their abundant resources are one of the reasons why they are widely consumed. The drawback of these materials is its brittle nature resulting in unavoidable cracking problems in the infrastructures. Further, the crack will initiate the corrosion of steel reinforcement and reduce structural durability. Calcium carbonate precipitating bacteria are the potential to heal the cracks in the cementitious composite if they are selected and treated carefully. This paper reviews different types of bacteria applied in concrete, and the methods can be used as a healing agent. This study recommends using bacterial cementitious composites as self-healing material, surface treatment, and crack healing agent.

Abstract
This study aimed to determine the composition of gold to silver minerals in rocks originating from Dongi-Dongi at 2 stations and to determine the composition of gold to silver minerals in rocks fixed to definite proportion. This study used secondary data, which were the result of rock analysis from Dongi-Dongi. The analysis showed that the gold composition from the three samples at Station 1 ranged from 0.01 to 0.99%, and the composition of silver ranged from 0.02 to1.46%. While the composition of gold at Station 2 ranged from 0.01to 2.55%, and the composition of silver ranged from 0.07 to3.02%. The results of the similarity analysis test of two variances and more than two variances showed that the composition of gold to silver has the same ratio in each sample, with Fcount <Ftable, then H0 is accepted. Therefore, it can be concluded that the ratio of gold to silver in each sample is the same, and follows the Law of Definite Proportion as stated by Proust that a chemical compound consists of elements with a mass ratio always remains the same. In other words, each sample or compound has a fixed composition of elements

Abstract
Some facts show that students often have difficulty in studying the kinematics and dynamics of motion. To overcome these problems, it takes learning experience that can help students build their knowledge about physics. One way is to connect the material physics with contextual phenomena because basically everything in nature can be learned based on physics studies. Semanggi Bridge located in Jember district is a connecting bridge that has a unique shape with three paths in the form of down, circle, and straight path. The studiesresults of kinematics and dynamics of motion on sloping and flat trajectories obtain physics quantities, ie position, distance, displacement, speed, velocity, kinematics and dynamics of motion on circular paths obtain physics quantities, ie angular position, angular velocity, angular acceleration, centripetal acceleration, centripetal force, and maximum speed. The studiesresults of kinematics and dynamics of motion can be used as a basis for designing contextual learning resources such as subject matter, sample questions, laboratory activities, and exercise questions related to contexts of physical phenomena.

Abstract
This research informs about multiple representation based physics learning. Multiple representation is an alternative learning strategy that is very important in physics. The delivery of material in various representations in the form of verbal, mathematical, picture and graphic will provide variations in the learning process so that it can make it easier for students to capture learning material. This is the advantage of multiple representation based learning. This study aims to analyze physics learning based on multiple representation of the learning outcomes of SMAN 3 Jember students, especially on Projectile Motion material. The type of research is quantitative descriptive with respondents consisting of 52 students of class XII MIPA SMAN 3 Jember. Respondents were given a pretest and posttest which consisted of 10 multiple choice questions including verbal, graphic, picture, vector and graphic representations. The research data obtained were analyzed by looking for the N-gain value to determine the category of increasing multiple representation based physics learning on student learning outcomes. The N-gain value obtained at 0.47 indicating that there was an increase student learning outcomes with the medium category.
