Abstract : The process of creating a prototype library based on historic architectural data and paving the way for virtually built heritage structures is known as heritage building information modelling (HBIM). The steps in HBIM are as follows: documentation phase, design phase, and three-dimensional (3D) model creation phase. Photogrammetry is used to generate 3D digital models of objects by uploading multiple photos using a certain software while crowdsourcing is the allocation of a task to a group of pe Full article
Abstract : This article designs a dual transformer, which can be coupled or tuned to two arbitrary frequencies. We formulate this problem as a minimization problem of the Reflection Coefficient ?_in, which allows us to find the impedances Z_1 and Z_2=Z_o R_l/Z_1 of the sections of the transmission line. We use Convex Optimization and the Dichotomous Search algorithm that allows us to find the parameters of the transmission lines. We show several results, and we include the case for operating frequencies of Full article

Abstract : Masonry structures originated from Europe with a wall thickness of greater than one layer and used mixed pozzolan mortar without a structural skeleton consisting of tied beams and columns. Many historical buildings were able to survive under the dynamic actions of medium earthquakes. The research attempted to carry out dynamic testing based on free vibration to determine the dynamic characteristics of masonry, such as natural frequency and damping ratio. This study aims to understand the charact Full article
Abstract : An alternating direction implicit scheme is presented to solve Poisson’s equation of fractional order using the shifted Grünwald-Letnikov estimate. Consistency and uniqueness of the method are discussed. It is shown that the rate of convergence in case of the ADI method is faster than the general five points formula. Exact and numerical solutions are constructed and compared. Then the efficiency of the proposed method is verified. Full article
Abstract : Lactobacillus plantarum IIA-1A5 is a lactic acid bacterium from local cattle of Peranakan Ongole with probiotic characteristics. This strain was found to be able to produce bacteriocin plantaricin IIA-1A5, which was proven to be able to inhibit Gram positive and negative bacteria as well as used as meat product preservative agents. Nevertheless, the stability of gene encoding plantaricin IIA-1A5 during the fermentation process remains unknown, which may reflect the stability of this strain to pr Full article
Abstract : Traffic volumes are widely believed to be key issues in the change in road surface conditions. The present study analyzed the impacts of traffic volumes of different vehicle categories on the change in road roughness as indicated by International Roughness Index (IRI) in Indonesia inter-city roads. The road volume-to-capacity ratio (VCR) was also considered in the modelling. The study used the data of 13 roads spanning 139.63 km on the north coast of Java. The analysis was made on three categori Full article
Abstract : Open air natural history museums act as a distinct type of museum that exhibits its collections out of doors aiming to record earlier life forms, ways of life, cultural customs and habits. Nowadays, museums including the Natural History Museums, look forward to increase the number of visitors and revisited visitors, throughout transforming museum visitors from passive consumers in a collection focused ‘static exhibition’ to active participants in a visitor centered ‘interactive technology exhibi Full article
