A blind recovery technique with integer wavelet transforms in image watermarking

The development of internet technology has simplified the sharing and modification of digital image information. The aim of this study is to propose a new blind recovery technique based on integer wavelets transform (BRIWT) by utilizing their image content. The LSB adjustment technique on the integer wavelet transform is used to embed recovery data into the two least significant bits (LSB) of the image content. Authentication bits are embedded into the current locations of the LSB of the image content, while the recovery information is embedded into different block locations based on the proposed block mapping. The embedded recovery data is securely placed at random locations within the two LSBs using a secret key. A three-layer embedding of authentication bits is used to validate the integrity of the image contents, achieving high precision and accuracy. Tamper localization accuracy is employed to identify recovery bits from the image content. This research also investigates the image inpainting method to enhance recovery from tampered images. The proposed image inpainting is performed by identifying non-tampered pixels in the surrounding tamper localization. The results demonstrate that the proposed scheme can produce highly watermarked images with imperceptibility, with an average SSIM value of 0.9978 and a PSNR value of 46.20 dB. The proposed scheme significantly improves the accuracy of tamper localization, with a precision of 0.9943 and an accuracy of 0.9971. The proposed recovery technique using integer wavelet transforms achieves high-quality blind recovery with an SSIM value of 0.9934 under a tampering rate of 10%. The findings of this study reveal that the proposed scheme improves the quality of blind recovery by 14.2 % under a tampering rate of 80 %

Integration of autograph technology for learning algebra

Numerous studies have shown the positive impact of integrating technological tool in the teaching and learning process of mathematics in the classroom. The teaching and learning of algebra utilizing dynamic softwares have been explicitly indicated in the Malaysian secondary school Mathematics syllabus (Ministry of Education, Malaysia, 2004). Teachers were recommended to utilize technological software and one such dynamic software just introduced in the Malaysian schools is the Autograph software. In this study, the effects of integrating the Autograph with computer algebraic system in teaching were explored. Specifically, the effects on mathematical performance in secondary mathematics and measures of mental load based on the cognitive load theory were investigated. The mean overall test performance for the Autograph group was 10.72 (SD = 3.47) and the mean overall test performance for conventional group was 13.03 (SD = 3.65). The independent ttest showed that there was a significant difference in mean test performance between the Autograph group and conventional group. Further, planned comparison test showed that mean overall test performance of Autograph group was significantly lower from those of the conventional group. This finding indicated that the conventional strategy group had performed better than the Autograph group. Findings in favor of the conventional strategy in teaching Quadratic Function implied several limitations and considerations that need to be further examined. Several factors that may lead to these findings are time constraints, lack of focus on the students’ part during the teaching and learning activity, teachers’ factor, and improved learning module for the students. In addition, these findings provide evidences of limited and deficient use of the technology, specifically in the teaching of mathematics at the secondary level

Instructional efficiency of utilization of autograph technology Vs handheld graphing calculator for learning algebra.

Learning mathematics is a major focus of educational institution at all levels. There is plenty of evidence that teaching secondary or college level mathematics with dynamic software can be effective, more efficient and above all it creates more enjoyable teaching and learning environment. Conceptually and pedagogically, technology assisted learning has provided positive impact on mathematical learning. Technology assisted approach helps move mathematic teaching and learning out of its “stand and deliver” mode to active group learning developing individuals’ potential as effective problem solvers and critical thinkers. The new technologies such as computers or calculators might affect the education system hence if used strategically the technologies provide learners the power of controlling what they are learning. This study aimed to investigate the instructional efficiency index of an interactive software Autograph and a hand held graphing calculator in comparison to the conventional way for teaching algebra. The Autograph has 2D and 3D graphing capabilities for topics such as functions, transformations, conic sections, vectors, slopes and derivatives. On the other hand, graphing calculator is a handy device that can be use for teaching mathematics which is able to create geometric figures, graph functions, inequalities or transformations of functions. The Paas Mental Effort Rating Scale developed by Paas and Merrienboer, 2004 were used to measure instructional efficiency of the three teaching modes utilized in the study. Hence a true experimental research design was used for this study with students selected at random to be assign to three groups. Four phases were conducted: 1)Introduction to Software, 2)Introduction to quadratic Functions, 3)Integrated teaching and learning using software, 4) Testing using Achievement Test and the Paas Mental Effort Rating Scale. The data were analyzed using ANOVA and post hoc analyses. Teaching and learning utilizing the graphing calculator was found to be instructionally efficient significantly, F (2, 98) = 11.1, p < .000 compared to the conventional and Autograph mode. Conventional strategy incurs low mental effort and high performance compared to used of Autograph. Graphing calculator condition thus far imposed relative low mental effort with high performance. Autograph condition imposes high mental effort with low performance. Each of these technology utilizations with their associated instructional efficiency may be useful for instructional researchers and educators in improving mathematical performance as well as in the utilization of technology in teaching and learning

Controllability analysis on delta temperature minimum to obtain operable and flexible heat exchanger network

The requirement to synthesis heat exchanger network (HEN) is to select design target, whichis temperature minimum difference (ΔTmin). The purpose of ΔTmin is to optimize betweencapital cost and energy recovery. Currently, research on 8Tmin effects on HEN is commonlyassociated with the design outcomes such as energy recovery and cost. There are severalresearch studies on the effect of 8Tmin towards HEN design. An optimal ΔTmin for heatexchanger network is set between 5oC to 50oC, (Kemp, 2011). Jensen and Skogestad (2008)explained about specified 8Tmin effect on the wrong decision in the design of HEN.Abdullahi (2012) has studied the effect on ΔTmin contribution for individual process streamin the heat exchanger system. Basically, HEN synthesis method using 8Tmin focus more ondesign prospective. Not so many studies on the 8Tmin effect to the controllability part.Based on a new trade-off plot proposed by Abu Bakar et al (2014), lower ΔTmin has betterdesign criteria (higher energy recovery), however, higher in total cost and lowercontrollability criteria (higher flexibility and lower sensitivity). On the other hand, higher8Tmin has lower design criteria, however, lower in total cost and higher in controllabilitycriteria

Integrated process design and control methodology for heat exchanger network

This paper explains about methodology framework development for integrated process design and control (IPDC) of heat exchanger network (HEN). In most of the IPDC HEN problems, the feasible solutions to the problems may lie in a relatively small portion of the search space due to the large number of variables and constraints involved. The ability to solve such problems depends on the effectiveness of the method of solution in identifying and locating the feasible solutions. Hence, one approach to solve this IPDC HEN problem is to apply a decomposition method. The method starts with defining the IPDC HEN problems and formulated as a mathematical programming. The IPDC HEN problem is decomposed into four hierarchical sequential stages: (i) target selection, (ii) HEN design analysis, (iii) controllability analysis, and (iv) optimal selection and verification. This method simultaneously combines the solution for both process design and process control problem by selecting a manipulated variable that represent both process design and process control which is minimum allowable temperature difference, ΔTmin. The decision on selection ΔTmin are guided by a new propose Trade-off plot that combine process design criteria and steady state process control criteria. A simple case study are used to demonstrate the methodology framework. The result shows that HEN with large ΔTmin is more flexible and easy to operate

Effects of higher order thinking module approach on pupils' performance at primary rural school

This study was to investigate the use of HOTS-based module approach on the performance of primary school pupils. This module was developed systematically using ADDIE model with adaptation on Cognitive Apprenticeship Model (CAM) as the framework to enhance Higher Order Thinking Skills (HOTS) among year five pupils. For the purpose of the study, a quasi-experimental, nonrandomized control group, pre-test-post-test and post delayed-test design was conducted on two intact groups. This study was conducted in two national schools located in the rural area, in one of the states in Malaysia. Two primary schools were selected to get a better view on the effects of using HOTS-based module in teaching and learning mathematics. Sample in school1 was a total of 76 pupils (38 pupils in the treatment group and 38 pupils in the control group), while for school2, 51 pupils (28 pupils in the treatment group and 23 pupils in the control group) participated in this study. The instrument used in this study was the twelve items problem solving test on the topic of Measurement and Geometry developed by the researcher. Reliability of the tests were .78 for pre-test, .79 for post-test and .71 for post delayed-test. The analysis of covariate (ANCOVA) indicated that no significant difference in the post test and post delayed test for both schools. This study showed that HOTS in mathematics is still new in Malaysia, even though module approach was used especially for those pupils in rural area. More time need to be given to the teachers and pupils in rural area school to be familiar and practice using HOTS. Hence it is recommended that HOTS-based module approach should be continued in teaching and learning Mathematics in the future
