Asphalt concrete pavement usually practices load repetitions and environment impacts. The quality of the pavement declines through the service life. However, the asphalt pavement can heal the micro cracks by itself. In the present investigation, slab samples of asphalt concrete were prepared at optimum asphalt cement binder requirement with the aid of roller compaction. Asphalt concrete prism specimens were extracted from the slab samples and subjected to four points flexural fatigue test at 20° C. The test was stopped when the stiffness of asphalt concrete declines to 50 % of its value at the start of the test. The beam specimens were subjected to external heating at 60° C for 120 minutes to enhance the viscoelastic properties through micro cracks healing through heating-induced healing method. Beams were tested under repeated flexural bending after the healing process. The variation in the stiffness, fatigue life, phase angle, dissipated energy and deformation after healing was monitored. It was concluded that the flexural stiffness, the phase angle, and dissipated energy were increased after healing while the deformation declines. The crack healing is recommended as a sustainable process to enhance the pavement quality. Keywords: Asphalt concrete, Healing, Micro cracks, Stiffness, Flexure, Dissipated energy, Phase angle.

Privacy-Preserving Data Mining (PPDM) develops algorithms for altering sensitive data. The private knowledge of a person, industry, or business organization remains private after the usage of data from the database. Data modification is one of the prominent privacy-preserving techniques used to alter confidential information available in the database and guarantees high privacy protection. In this paper, a new masking technique is proposed for hiding sensitive numerical attributes that are later analyzed using clustering algorithms, namely k-means, filtered clusters, and density-based clusters. The proposed technique is used to hide confidential numerical attributes. After modification, the proposed algorithm compares the original and the modified data and ensures that all the data items are altered or not. Experimental evaluation is illustrated using the employee dataset. The accuracy is calculated based on the comparison of the original and the modified data set in terms of data items found in the number of clusters. For every clustering technique, both the original and modified at a set are divided into two, three, four, and five, clusters. Based on the performance metrics, the k-means algorithm gives the best result compared to other algorithms. The results obtained from the proposed technique are compared with the existing approach. The experimental result indicates that the newly developed method is more efficient than the existing approaches. Keywords: Data masking, Data swapping, Sensitive data, Privacy-Preserving Data Mining, Clustering, Data hiding.

Iris image has been adjudicated one of the most reliable biometric traits for authentication as a result of its unique patterns, stringency to spoof attack and reliability. However, studies have revealed that inefficient classification sorts and techniques leading to classification errors and inaccurate matching has characterized its processes in many authentication and identification applications. Additionally, most of the existing works in the domain are based on single image classification, and major drawbacks of these methodologies remains insufficient learning input and classification errors. The current work uses Deep learning neural networks (DLNN), a subset of artificial intelligence that are effective in learning complex features from data, such as images. Majorly, the work is focused at classifying both left and right human iris images. Data for the work was acquired from the CASIA-Iris-lamp dataset (http://biometrics.idealtest.org). The dataset contains 16,163 iris datasets, and 20 iterations were passed on the data during modeling to determine the accuracy of the model. Performance metrics such as sensitivity, specificity and accuracy were used to evaluate the performance of the model. Experimental results show that the model performed well with classification accuracy of 99.57% which is relatively an improvement over the existing model that was used as a benchmark with 93.35%. The model correctly classified and predicted all images belonging to the right category as right irises, while it wrongly predicted 14 images belonging to the left category. Connotionally, the right iris recorded higher accuracy compared to that of the left iris. Keywords: Iris, Classification, Deep Learning, CNN, Accuracy

This work aims at studying the compressibility properties of soil in Calabar Municipal, Cross River State, Nigeria. Also, these properties are correlated with the Atterberg Limits of the soil. The magnitude of the overall compressibility prediction of regression model depends on several variable such as the compressive index (Cc), coefficient of consolidation (Cv), coefficient of compressibility (Av), and coefficient of volume compressibility (Mv), which are determined by a consolidation test in the laboratory, by carrying out oedometer test. However, the test itself is time consuming and involves lots of calculation hence, the non-linear regression model of this research focuses on determining the relationship between the compressibility characteristics of the soil and its Atterberg Limits. The regression models developed for the ten samples using the Wolfram Application would enable for prediction of the different Compressibility Properties of the soil in Calabar Metropolis relative to its Atterberg Limits thereby reducing rigorous time-consuming activities. The regression models developed where observed to have a Coefficient of Determination (R2) value above 90% which indicated the adequacy of the model to be employed for prediction. R2 for LL, PL and PI are of values 0.955692, 0.951884 and 0.944464 respectively on Mv, the R2 for LL, PL and PI are 0.97744, 0.976234 and 0.971964 on the Cv. Also, models for Cc gave an R2 with values 0.990806, 0.99053 and 0.990396 respectively. Finally, Av on the LL, PL and PI have R2 as 0.969628, 0.965995 and 0.963419 respectively.

A consolidation (Oedometer) test can be used to measure the soil's compressibility characteristics, which indicate how much settlement will occur. The Atterberg limit test is very simple and quick in comparison to the Oedometer test, which is more expensive and time-consuming. Soil samples from various areas in Awka, Anambra State, and the surrounding area were gathered for this research. Laboratory investigations were carried out on the soil samples in order to determine the Index properties and compressibility parameters namely liquid limit (LL), plastic limit (PL), plasticity index (PI) and compression index (Cc). Based on the outcome of the experiments, non-linear empirical models were subsequently developed using simple regression analysis. This makes it possible to define the compression index as a function of the soil index (Atterberg limit) characteristics viz; LL, PL, and PI in the study area. A good agreement was found between the model’s predictions and the actual values of the compression index. The regression models were validated with a 95 percent confidence level based on the coefficient of determination (R2) values, which show a strong link between the variables.

Cybercrime is on the rise as the digital world continues to expand. Gathering legitimate evidence is what digital forensics is all about. In a legal context, such proof is essential since it demonstrates the victim's crime beyond a reasonable doubt. It is crucial to keep evidence using a good evidence management system to ensure its admissibility in court during trials. We suggest a proxy re-encryption system that only works in one way for delegating power. The suggested approach will provide the safe delegation of access to electronic evidence. Proxy re-encryption as a means of incorporating access control into a secure evidence management solution is validated by the re-encryption scheme's enhanced sense of security. Within this study, we compare and contrast the many different systems that have been presented over the years. Future proposals for improved evidence handling could benefit from this investigation.

The Rainfall is a crucial hydro meteorological variable in arid and semi-arid region due to its yawning impact on agriculture, drinking water and energy sectors. Junagadh (Gujarat-India) region reels under rainfall uncertainties and thereby water resources and crop production suffer a lot. Rainfall is highly complex, nonlinear, and dynamic in nature and affected by many interrelated meteorological parameters. Further the temporal and spatial variability causes more uncertainty in its occurrence. Despite significant contribution of advance computing techniques, the rainfall prediction yet remains a tough challenge. Holt-Winters model is a time series model and it relies on three aspects of the time series: a typical value (average), a slope (trend) over time, and a cyclical repeating pattern (seasonality).Annual rainfall data often exhibits trend and seasonality and hence, the Holt-Winters models could be the best choice for its prediction. This study examined ability of three different types of time series models (Holt-Winters model (HW), Multiplicative Holt-Winters (MHW) and Additive Holt-Winters (AHW)) in predicting annual rainfall for Junagadh (Gujarat-India) region. Performances of the models were evaluated by using refined Willmott’s index (dr) and mean absolute error (MAE) evaluation measures. All the three models performed better and are recommended for forecasting annual rainfall of the selected region and the similar hydro-meteorological regions.
