It is developed by combining an overlapped image component series of a large image, which is difficult to be focused on using a normal camera due to a large field of view. Measuring the quality of panoramic images is a challenging task. Therefore, the objectives of this research are to find the attributes of visual quality of panoramic images and to propose predictor variables for a statistical model for the quality of panoramic images of mural paintings. Authors have used a proposed novel method for creating panoramic images of mural painting. In this study, authors researched on the quality attributes of digital images. Accordingly, color balance, noise and distortion were identified as the two most critical factors which affect the overall quality of the panoramic images. Authors visited three temples and captured digital images of mural paintings of large scale using a simple method. Then, panoramic images were created using three methods: the novel method with other two methods, Photoshop (available in the market) and Hugin (open source software). Subjective evaluation was applied through experts in the field of Visual Arts. Participants were asked to rate the quality using four-point Likert scale for color balance, noise and distortion as predictor variables and overall quality as the response variable of panoramic images. Ordinal logistic regression was fitted through Minitab statistical package and the results showed that color balance and noise and distortion are two important attributes for the quality of the panoramic images. Moreover, the collected data fit the model at a higher accuracy.

As many n-nitrosamines are carcinogenic, they are highly regulated in final rubber articles and during manufacturing process. 2-(Morpholinothio benzothiazole (MOR) is the primary accelerator used in vulcanizing systems. It produces nitrogen toxic gases (nitrogen oxide and amine gas) which are carcinogenic. In this research MOR was successfully replaced with N-tert-butyl-2-benzothiazole sulfenimide (TBSI) accelerator which has no carcinogenic effect. The main objective of this research is to maintain its original properties while replacing MOR with TBSI accelerator. This study was conducted and test samples were made of bonding rubber compound that is used to make the bonding layer of tyres which is the common part in all type of solid tyres. Physical-mechanical and bonding properties were analyzed for MOR and TBSI added bonding compound samples. Tensile, hardness, density and rheological using Oscillating die rheometer properties were also measured to maintain the quality of the tyre. The property change of bond layer can affects the other tyre layers. So, it can lead to failure of curing process or failure in performance of the tyre during the applications. The TBSI curing characteristics are closer to MOR sample. However other physical properties like hardness and density of TBSI samples were bit lower but they were in the required level as a bonding layer compound. Substitution of MOR by ‘safe TBSI’ compounds are still active as accelerators, but do not form carcinogenic gases.","PeriodicalId":52314,"journal":{"name":"Advances in Technology Innovation","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82965764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Permeability, the way of ingress of water into wood mass, is one of the most variable properties of timber and it further influences nearly all the physical properties of wood. Wood exposed to high humidity conditions or to liquid water during use may be subjected to biological deterioration which makes equilibrium moisture content of wood very important. Equilibrium moisture content is the moisture level where the wood neither gains nor loses moisture since it is at equilibrium with the relative humidity and temperature of the surrounding environment. Sixteen randomly sampled specimens of each of the wood of Sterculia rhinopetala and Albizia ferruginea species (heartwood and sapwood) with dimensions 3 cm x 3 cm x 3 cm were exposed at various relative humidity conditions of 30 %, 45 %, 60 %, 75 % and 90 % in a temperature and humidity-controlled climate chamber. The order of water uptake in terms of percentage volume is arranged from the lowest to the highest. Sterculia rhinopetala heartwood had the lowest uptake per volume with a value of 0.31 %. On the uptake per weight Sterculia rhinopetala heartwood again had the lowest uptake whilst Albizia ferruginea had the highest with a value of 6.77 %. The sapwood of Sterculia rhinopetala had a relatively higher uptake per volume value of 0.53 % and a value of uptake per weight of 0.72 % compared to the heartwood. The equilibrium moisture content values of Sterculia rhinopetala suggests that it can have minimal dimensional changes when used in both the Southern and the Northern parts of Ghana.\u0000 ","PeriodicalId":52314,"journal":{"name":"Advances in Technology Innovation","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75507486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper records the personal experience of the researcher as a language practitioner using corpus analysis technology in designing teaching learning material to achieve the objectives of a language course for undergraduates of low English proficiency (LEP) studying in an English medium instruction (EMI) context. Although this exercise posed challenges for the language teacher who is a ‘non-expert’ to the field, the researcher documents its positive and promising outcomes as proof to support more extensive ‘non-expert’ teacher-driven, student-participatory corpus based English language learning methodologies.","PeriodicalId":52314,"journal":{"name":"Advances in Technology Innovation","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75397125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
