The majority of fuzzy time series forecasting (FTSF) algorithms assess forecasting accuracy using an error-based distance. The predicted value is defuzzified to a crisp number and the error-based distance will be computed. Defuzzification causes some information to be lost, which leads to its inability to comprehend the level of uncertainty that has been preserved during the forecasting process. This paper proposes an enhanced FTSF model with forecasting accuracy developed based on a new hybrid similarity measure combining the centre of gravity and area and height. Three properties of the hybrid similarity measure are presented. The FTSF model is implemented in the case of the Malaysian unemployment rate. The findings indicate that, on average more than 94% of the predicted value was identical to historical data. The forecasting accuracy is produced directly from the forecasting value without undergoing the defuzzification process, which can preserve some information from being lost. .....

A mathematical model known as Geometric Brownian motion has proven to be an effective tool that can be deployed to forecast the price of goods in the future due to the presence of random terms, which represent the stochastic or random fluctuation of prices over a given period of time. The success of this model revolves around the estimation of its governing parameters. To efficiently predict the price of goods, using the Geometric Brownian Motion model (GBM), one needs to determine the value of returns and use the calculated returns to estimate the value of drift as well as volatility. This research used the value of volatility and drift terms obtained from real data of sugar in the months under review. The method has shown to be very reliable in capturing the intelligent trend in the price of sugar in Malaysia. The model was able to stimulate the pattern of the predicted price that shares a great resemblance to the actual price of sugar. The result obtained is very encouraging and pla.....

International Financial Reporting Standards (IFRS) is a set of international accounting standards, which facilitate the reporting of financial results of companies. The purpose of this study is to examine the predictors and the effect of adopting IFRS on the organizational level in Libya. The population consists of 2,212 respondents. Using the random sample technique, the sample size accounted for 425 and a total of 248 responses were collected. The data was analysed using SPSS and AMOS. SPSS was used to examine the data and conduct the descriptive analysis while AMOS was used to conduct the regression analysis. The study proposed that perceived organizational factors (POF) (accounting capabilities (AC), top management support (TMS), and organizational readiness (OR), perceived technical factors (PTF) (compatibility (COMP) and complexity (COX), and perceived environmental factors (PEF) (government regulation (GR) and external pressure (ER) will affect the adoption of IFRS w.....

Student-lecturing is an innovative teaching model which allows students to express their problem-solving strategies and ways of thinking using mathematical language. It not only allows students to demonstrate their thinking process, but also creates a relaxed classroom environment for students to overcome their fear of expressing mathematics, thus changing their attitude toward mathematics. However, the traditional teaching methods place students in a passive accepting position, causing them to believe that mathematics is difficult and dull, leading to a loss of interest in Mathematics. This study analyzed the effect of the student-lecturing teaching model on student attitude toward mathematics through a one-and -half-year controlled-experiment with eighth-grade students in Shaoguan, China. The result of this study shows that the student-lecturing teaching model not only helps to develop students' problem-solving and communication skills, but also gives students the opportunity to expr.....

Pineapple (Ananas comosus) is widely consumed and appreciated not only due to its taste and aroma and to its nutritional and antioxidant properties, including its vitamin C and phenolic contents. In an attempt to explore new antioxidant leads, pineapple waste is often neglected in the pineapple industry. Fruit processing has considerably higher ratios of by-products and pineapple by-products are not exceptions as they consist basically of the residual pulp, peels, stem, and leaves. Pineapple waste is a by-product resulting from canning processing of pineapple that produces about 35% of fruit waste and leads to serious environmental pollution. The objective of this study is to determine whether different varieties and parts of pineapple waste (peel, core, crown, and stalk) can affect and give the highest amount of natural antioxidant activity. In this study, the antioxidant activities of different parts of three pineapples (N36, Madu, and MD2 were measured using the DPPH method. Methano.....

The application of biopesticides is progressively encouraged for its advantages associated with environmental safety and high biodegradability. The objectives of this study were to compare the phytochemical constituents, anti-feedant, and molluscicidal activities of spices against the giant African land snail, Achatina fulica. The spices evaluated were clove (Syzygium aromaticum), cinnamon (Cinnamomum verum), black pepper (Piper nigrum), cumin (Cuminum cyminum) and coriander (Coriandrum sativum). Phytochemical constituents of spices were screened by qualitative standard protocols. Anti-feedant activity was investigated by the leaf disc no-choice bioassay method and molluscicidal activity was evaluated by a 72-h contact toxicity test. The phytochemical screening showed positive results for tannins, saponins, alkaloids, flavonoids, terpenoids, and phenols in clove, cinnamon, cumin and coriander ethanolic extracts whereas only tannins, alkaloids and terpenoids were found in the black pepp.....
