Extrema points are usually applied to solve everyday problems, for example, to determine the potential of a created tool and for optimisation. In this study, extrema points were used to help determine the region of interest (ROI) for the iris  in  iris  recognition  systems.  Iris  recognitionis  an  automated  method  ofbiometricidentification  that  uses mathematical  pattern-recognition  techniques  on  the  images  of  one  or  both irisesof  an  individual'seyes,  where  the complex patterns are unique, stable, and can be seen from a distance. In orderto obtain accurate results, the iris must be localised correctly. Hence, to address this issue, this paper proposed a method of iris localisation in the case of ideal and non-ideal iris images. In this study, the algorithm was based on finding the classification for the region of interest (ROI) with the help of a Support Vector Machine (SVM) by applying a histogram of grey level values as a descriptor in each.....

Numerous decisions in our daily lives require the ability to calculate, solve problems, and employ concepts and skills in mathematics. However, students always have bad perceptions in mathematics as this subject is often challenging for  students  to  master.Reports  on  issues  about  students’  mathematical  education  have  been  raised  by  many mathematics educators. Among of the issues are about difficulties in understanding mathematical concepts, attitudes towards  mathematics,  low  achievement  in  mathematics  and  many  more.  Hence,  the  aim  of  this  study  is  to  explore students’  perceptions  and  attitudes  towards  mathematics  by  analyzing  the  impact  of  teaching  application  of mathematics  to  the  students.  The  data  were  collected  from  Computer  Science  students  where  each  participant  was assigned to complete self-reported and close ended questionnaire. In this study, examination on .....

This article is concerned with the assessment of feelings that Japanese junior high school students have towards the course unit learning of mathematics curricula. To accomplish this purpose, 616 junior high school students of a typical public school were surveyed regarding their feelings towards these course units and a two-step analysis was carried out. The first part consisted of the tabulation of Likert scale type survey with 5 levels of evaluation from 1 (‘not good at’) through 5 (‘good at’) aimed to evaluate their feelings towards learning mathematics in general as part of their educational activity. Next, we looked only into the students who responded ‘no problem’. As a matter of fact,these respondents accounted for 181 students in all with 44 of them in first year, 75 in second year, and 63 in third year. Now focusing strictly on these students, we performed a correspondence analysis of their feelings towards the course units. The results are discussed in terms of t.....

Reagent  grade  of  calcium  and  magnesium  hydroxides  were  used  in  this  study  to  treat  acid  mine  drainage  (AMD)sample. AMD sample was collected from a tin tailing pond that located in Pengkalan Hulu, Perakwhich as pHaround 2.87±  0.01. pH  values  had  increased  after  treated  with  calcium  hydroxide  (Ca(OH)2)  and  magnesium  hydroxide (Mg(OH)2), respectively. The maximum pHvalues obtained was 11.35± 0.01by using 1.0 g of Ca(OH)2at interval time 5 min. ForMg(OH)2, the highest pHvalue can be obtainedwas 7.22 ± 0.01 by using 1.0 g at interval time 30 min. The  concentration of heavy metals such as aluminum, copper, iron, manganese, nickel  and zinc  were reduced after reaction withboth materials.For examplesaluminum concentration was reduced from 110.33 mg/L to 2.80 mg/L and 0.01 mg/L by using 1.0 g of Ca(OH)2and Mg(OH)2, respectively...

The main purpose of this study is to determine the prevailing modern teaching methods in teaching-learning process. The descriptive-quantitative method was employed using a questionnaire as data gathering instrument. Frequencies, percentages and weighted mean were used to treat the data. The target population of the study was 286 of the senior high school students of the University of La Salette, Inc. – Santiago City during the school year 2018-2019. The study showed that modern teaching method has a positive impact on the learning of the students. It gives a lot of benefits that characterize a life-long learning. Also, through the modern teaching a method, students would be able to learn some values that would lead them to success. It also revealed that among the four-teaching method, brainstorming is the most effective for the students to learn. Based on the findings and conclusions of the study, it was recommended that teachers need to continually develop a method that would let t.....

The review was aimed to review the phytochemical of the Polyalithia longiflia. Phytochemical screening for all parts of Polyalithia longiflia have been done and shown most of the chemical group compounds such as glycosides, Sterol, Carbohydrates, terpenoids, flavonoids. 174compounds have been isolated from five parts (leaves, steam bark, seeds, fruits, root) of Polyalithia longiflia, these compounds have been drown their structure. Leaves of Polyalithia longiflia were extracted and isolated 99 compounds most of these compounds were terpenoids, 59 compounds were isolated from the stem bark belong to different chemical groups such as Terpenoids, Alkaloids, Phenol, Fatty acids, and Steroids, 16 compounds were isolated from the fruit from several chemicals groups, 11 compounds were isolated from the root,7 compounds were isolated from the seeds which belong to different chemical groups which are Terpenoids, Fatty Acids, and Carbohydrate. Many of these compound have been used in medical fil.....

This study has developed a model of peace based on al-Quran. Considering this situation, the Indonesia University of Education and the University of Education Sultan Idris in Malaysia undertook an initiative to jointly identify the local value that has contributed to the perceived and expected peace based on al-Quran in school communities. In this case, schools successfully establish a climate of peace, respect, compassion, fair, ethical and mutual respect. Violence varieties, which are done by teachers and students, have been already very alarming even in the category of emergency. Peace education is an effort to develop a culture of peace schools reinforced with religious values, that education has the capacity and the responsibility to lift humanitarian issues, about how people live side by side with others, and have concern for other human beings. This is indeed the true crisis in education. This study uses qualitative and quantitative approaches. A quantitative approach is used to.....

Black tilapia (Oreochromis mossambicus) fish scales were used as a source of natural hydroxyapatite (HAp) since it is cheaper than synthetic hydroxyapatite and safer than animal origin such as bones. This study investigates the preparation of natural hydroxyapatite from tilapia fish scales (FsHAp) by thermal technique followed by ball milling and spray dried to produce FsHAp powder. The effect of milling time on the particles size of FsHAp was investigated. In this study, Mastersizer 2000 was applied to measure the particles size of FsHAp. Field emission scanning electron microscope (FESEM) was used to investigate the morphology of the FsHAp powders whereas x-ray diffraction (XRD) and Fourier transform infrared (FTIR) were used to verify the presence of FsHAp. From the experimental results, it was found that the optimum milling time is 48 hours which produced smallest particles of FsHAp at about 1.86 ?m. The spray-drying method produced different sizes of FsHAp ranging from 2.18 micron.....

Epoxy/silica/kenaf composites were fabricated using a simple technique of hand lay-up method. The effects of silica addition on mechanical properties of epoxy/kenaf composites were studied by varying silica contents, ranging from 10 to 50 wt% while kenaf fibre was fixed at 24.5 wt%. Non-woven kenaf fibre used in this research was treated with 3 wt% NaOH to improve surface interaction between epoxy matrices. The composites were fabricated using hand lay-up method in metal mould and then they were pre-cured at 80 oC for 1 hour and postcured at 110 oC for 1 hour. The mechanical properties of composites were examined by means of flexural and impact tests. It is found that silica content of 30 wt% has produced epoxy/silica composites with highest impact strength of 6.5 kJ/m2. However, addition of treated kenaf fibre has given the strongest composite with the values of 54 MPa for flexural strength and 10.6 kJ/m2 for impact strength. Field emission scanning electron microscope (FESEM) was app.....
