This paper presents an Optimized Mutation Testing (OMT) technique based software defect prediction model using the concept of hybrid metaheuristic technique. Here, hybridization of OMT with Enhanced Learning-to-Rank (ELTR) is used for the feature extraction from mutation testing based data generation mechanism. In the proposed approach, first hybrid technique is used for the test data feature extraction then this data is exercised to cover all mutants present in the specific program under test and then machine learning based Random Forest as an ensemble classifier is used as a classifier. The proposed method can improve the testing as well defect prediction efficiency by deleting the redundant test data. In this research work, two models are implemented for the software defect prediction using the ELTR and LTR. At last, the performance parameters such as Detection Rate, Defect Predication Value, Execution Time, Percentage of Fault Negative Rate and Percentage of Fault Rate are measured and compared with the existing work to validate the proposed model.","PeriodicalId":11002,"journal":{"name":"Day 1 Tue, March 23, 2021","volume":"220 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86216515","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}

The trial-and-error method possesses an infinite possibility of passwords in patterns/ pin locks for unlocking the devices. The levels of security ensure that only a limited number of trials are possible before any device blocks itself or makes unlocking harder. In these circumstances, especially when a victim is a deceased person (e. g. an abetment in suicide case), the password is practically impossible to attain through the authorities. However, the data can be retrieved with the unique and distinctive method of Chip-off analysis. In this study, a password protected mobile phone was retrieved from a deceased individual and only the analysis of his/her mobile could lead to investigative insights for catching the perpetrator. The Chip-off method has several difficulties and a password/ pin protected device increases the difficulties for analysis several folds. This study highlights the significance of chip-off analysis in achieving accurate importing and extraction of maximum data along with the use of the hardware/software, MSAB, XRY and other software.","PeriodicalId":11002,"journal":{"name":"Day 1 Tue, March 23, 2021","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90641168","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}

Using IoT, it is possible to connect any number of objects and in any context, giving rise to a diverse range of services. Hence power management, data storage, service discovery, service management, service creation and resource management need a more sophisticated mechanism and a better infrastructure. However, a single IoT that is power-constrained will not be able to tackle all the data that is generated. Hence cloud computing plays a crucial role by integrating with the IoT in such a way that the future internet and envisioned IoT is achievable. There are a number of challenges involved of which data trimming is common challenge. Due to unnecessary communication, the data this sent to the cloud may be interrupted. Hence to prevent this, data is initially preprocessed following which it is trimmed and then transferred to the cloud. This aspect of data processing can be carried out through Fog Computing or Smart Network that serves as a smart gateway. In this paper, we have introduced a novel concept Fog computing as the smart gateway. The results have been analysed and tested with respect to bulk-data synchronizstion Delay, bulk-data upload delay, jitter, synchronization delay and upload delay.","PeriodicalId":11002,"journal":{"name":"Day 1 Tue, March 23, 2021","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78878937","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 study aimed to determine the level of environmental toxicants in goats tended by rural farmers. Fur and blood samples were carefully collected from sixteen (16) goats in open range husbandry (ex situ) at four sites in Amawzari, Imo State, Nigeria. The samples were digested and analyzed separately to determine the concentrations of some environmental toxicants (heavy metals). The concentrations of Pb, Cr, Cd and Ni in blood were 0.01 to 0.05, 0.01 to 0.07, 0.00 to 0.01 and 0.05 to 0.12 mg/kg, while their concentration in fur were 0.02 to 0.03, 0.001 to 0.006, 0.00 to 0.00, and 0.04 to 0.05 mg/kg, respectively. Pearson correlation analysis show very strong positive relationship between Pb in blood and Pb in fur (r = 0.855, p < 0.01) and Ni in blood and Ni in fur (r = 0.811, p < 0.01). The order of abundance of the four heavy metals tested in goat fur and blood is Ni > Cr > Pb > Cd. Based on our findings, the concentrations of heavy metals in blood were higher than its corresponding values in fur. Thus, consumption of meat processed from these metal-contaminated goats and utilization of their blood to manufacture blood meal for pigs and poultry birds will result to bio-magnification of heavy metals in man and animals. Therefore, we recommend that rural farmers should be enlightened on health challenges associated with in situ form of animal husbandry.","PeriodicalId":11002,"journal":{"name":"Day 1 Tue, March 23, 2021","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90447000","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}

Collections of soil samples were carried out fortnightly twice a month for four months. The extraction of soil macroinvertebrates was carried out using Berlese-Tullgren funnel extractor, and elutriation technique. The mean values of 6.93+/-0.25 were recorded for pH, 32.08+/-0.52oC for temperature, 15.60+/-1.22 for moisture content, were recorded for fallowed soil, and 4.43+/-0.16 (pH), 30.95+/-0.19oC (temperature) were recorded for cultivated soil. A total of 17 soil macroinvertebrates species comprising of 11 orders, from four classes were encountered. Out of the 517 individual soil macroinvertebrates encountered, 327 individuals representing four classes were present in the fallow land while 190 individuals representing three classes were present in the cultivated land. The most dominant species in terms of abundance in the fallowed land site included; Cryptotermes sp 67(20.49%) > Blatta sp 56(17.12%) with Hogna sp 1(0.0.30%) the least; while Cryptotermes sp. 79(41.58%) >Lasius sp 30(15.79%) > Lumbricus terrestris 21(11.05%) represents the dominant species in the cultivated soil with Paraponera sp 1(0.53%) the least. Soil temperature showed positive correlation with the abundance of Clitellata (r = 0.851; p < 0.05) and Insecta (r = 0.826; p < 0.05) and Soil pH showed positive correlation with the abundance of Diplopoda (r = 0.911; p ≤ 0.05). In conclusion, it could be deduced from the study that human activities in the cultivated site perturb soil macroinvertebrates community structure which is reflected in the relative abundance of soil macroinvertebrate from the two sampling sites. The results obtained in this study could be a piece of pointing information for the conservation and management of the soil macroinvertebrates giving their functions in balancing agroecosystems.","PeriodicalId":11002,"journal":{"name":"Day 1 Tue, March 23, 2021","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90338093","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}
