Geochemical implication of hydrocarbon exploitation on soil around crude oil producing area of Uzere, Niger Delta region, Nigeria

Abstract The crude oil sector in Nigeria continues to be a significant source of income and foreign currency. However, operations related to oil exploration and production have the potential to seriously alter the environment, having an impact on ecosystems, water bodies, and human life. In many cases, pollution indices are viewed as a useful instrument for thoroughly evaluating contamination levels. Additionally, they may have a significant weight when evaluating soil quality and the forecast of long-term ecosystem viability, in the case of farmlands, in particular. Atomic absorption spectrometry was used to examine the heavy metal contents (AAS). Potential ecological risk index, Geoaccumulation index, Nemerow pollution, Pollution load index, Contamination Index (CI), and metal pollution index were the seven indicators employed in the study. The concentration of heavy metal such as Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Nickel (Ni), Lead (Pb), Chromium (Cr), Arsenic (As). Ranges from 11.9 to 184.1, 920 to 8870, 1.1 to 9.9, 9.7 to 60.4, 0.001 to 0.001, 2.4 to 34.7, 2.2 to 11.5 and 0.001 to 0.001 mg/kg respectively. The correlation matrix showed that there were positive correlation between Mn and Ni; Fe and Cu, Zn, Pb, Cr; Cu and Cr; Zn and Pb, Cr; and Pb and Cr; while a negative correlation exist between Cu and Ar, Cr and Ar.PCA showed that 75% of the samples in PC1 has loadings, in PC2, they have 50% of the parameters having loadings, in PC3 25% of the parameters had loading while in the PC4, 12.5% of the entire parameter has a loadings.Findings from aforementioned indices revealed that analyzed soil samples are polluted.
About the List of Specialties and Areas of Higher Education Training

The article raises the problem of compliance of specialties and areas of higher education training with professions and scientific specialties. In recent years, the specialties and areas of training have been enlarged. Training in engineering specialties has been drastically reduced. It is proposed to expand the list, increasing first of all engineering specialties. The issue of the list should be solved systematically, comprehensively, together with the list of scientific specialties, as well as the register of professional activities and the list of professions. The list of specialties and areas of training should be the same for higher and secondary vocational education. Examples are given for the USGS group “Biotechnologies and Food Technologies”.
Introduction of the Ideology of Quality in the System of Vocational Education

The problem of using the principles of the quality management system to create an environment in educational organizations that educates specialists of the new modern economy is considered. It is proposed to focus the educational process at the university on the formation of students’ key competence — “commitment to quality”. The ideology of quality should prevail in educational organizations, which should be “imbued” with all employees and teachers. The model of the educational process implementation is presented, in which the resources spent will give the greatest result in the form of achieving the specified requirements and goals in terms of meeting the expectations of consumers.

Coherent states with minimum Gini uncertainty for finite quantum systems

Abstract Uncertainty relations <?CDATA $\Delta(\rho)\ge \eta_d$ ?> in terms of the Gini index are studied. The “Gini uncertainty constant” <?CDATA $\eta_d$ ?> is estimated numerically and compared to an upper bound <?CDATA $\tilde \eta_d\ge \eta_d$ ?> . It is shown that for large d we get <?CDATA $\tilde \eta_d\approx \eta_d$ ?> . States <?CDATA $|{g}\rangle$ ?> with minimum Gini uncertainty and displacement transformations are used to define coherent states <?CDATA $|{\alpha, \beta}\rangle_g$ ?> (where <?CDATA $\alpha, \beta \in {\mathbb Z}_d$ ?> ) with minimum Gini uncertainty <?CDATA $(\Delta[|{\alpha, \beta}\rangle_g\;_g\langle{\alpha, \beta}]\approx \eta_d)$ ?> . The <?CDATA $|{\alpha, \beta}\rangle_g$ ?> resolve the identity, and therefore an arbitrary state can be expanded in terms of them. This expansion is robust in the presence of noise.

Matrix-based Genetic Algorithm for Mobile Robot Global Path Planning

In this paper, a new variant of genetic algorithm, matrix-based genetic algorithm (MGA), is proposed, which represents the population of genetic algorithm by matrix, and achieves evolution by matrix operation. Applying it to the 2D global path planning problem of robot, MGA has better accuracy and running speed than the basic genetic algorithm. Specifically, the average path length obtained after convergence of MGA is closer to the actual shortest path length than that of the basic genetic algorithm, and, due to the parallelism of the MGA in matrix operations, the MGA runs in 1/2 the time of the traditional genetic algorithm when using the NumPy library. Two experiments comparing shortest path lengths demonstrate that MGA has better stability and can cope with complex environments. In order to enable the algorithm to have better accuracy, this paper also explores the effect of whether to use elite strategy on the accuracy of the shortest path of the algorithm. In addition, the effect of different pathfinding algorithms on the computing time of the algorithm is explored to speed up the operation of the algorithm.
Implementation of A* Shortest Path Finding Algorithm in a Transport Robot with Robust Turning Mechanism

Autonomous transportation is a rapidly emerging field of technology with potential applications ranging from safe delivery of goods in disaster sites or hospitals to intelligent warehouse logistics management. However, an overwhelming majority of this emerging process focuses on high-end quality products with prices which deny entrance into the field for most. Herein, we demonstrate the development of a proof-of-concept autonomous line-following robot that could serve as a low-cost budget solution for this domain. Rather than using performance-demanding AI approaches, the utilization of the A* path finding algorithm in combination with a line-following movement approach enables the use of the low-cost single-board computer, raspberry pi. Infrared sensors are used in complement with a grid of black lines to enable the robot's movement. Additionally, this work dabbles in the computational performance of the A * algorithm alongside the development of a highly robust turning mechanism.
Action Rule Mining With Predications on Semantic Representations of Data

Without a doubt, the World Wide Web (WWW) has already altered the way we share knowledge. The exploitation of the web is one of the biggest challenges in the area of intelligent information management. The Semantic Web was presented to ease this situation by taking the WWW into a distributed global system for knowledge representation and computing. In this work, we study action rule mining in the semantic web data and aim to assist users in uncovering previously unknown and potentially useful workable strategies. We present rule-based action rules and object-based action rules for extracting actionable patterns from a large graph dataset without the extra step of converting graph data into transaction data.
An Improved blockchain-based secure medical record sharing method

Abstract Today, the confidentiality and security of patient medical records is of great importance. A database where patient records are kept should not fall into the hands of malicious persons. In addition to keeping medical records confidential and secure, their sharing among various entities such as individuals or institutions must be auditable and controllable. This study proposes a method that enables the storage, access, and sharing of medical data without risking security vulnerability. In the proposed method, data are stored on the cloud, whereas data access information and hash values are stored on a blockchain. The three consensus mechanisms (Proof ofWork (PoW), Proof of Stake (PoS), and Proof of Authority (PoA).) for the proposed scheme are implemented and compared with studies in the literature in terms of security analysis.The performance analysis of the proposed method showed that the Proof of Work gives the best result in terms of block size, while the Proof of Stake gives the best results in terms of block creation time and memory usage. The security analysis showed that the proposed method has many security features and is strong against attacks.
Subsurface Relationships between the Sebree Trough and Carbonate-Siliciclastic Mixing in the Upper Ordovician Lexington-Trenton and Point Pleasant-Utica Intervals in Ohio, USA, using Multivariate Statistical Well Log Analysis

The Upper Ordovician (lower Katian; upper Chatfieldian-lower Edenian) Lexington-Trenton limestone and Point Pleasant-Utica shale intervals are important subsurface stratigraphic units across Ohio as they are the sources of significant conventional and unconventional hydrocarbon resources. However, both units exhibit anomalous distributions across the state and heterogeneous relationships, especially in areas where they intertongue. The limestone units show a peculiar SW-NE thinning trend across Ohio, whereas the overlying shale units show an anomalous thickening along the same trend—a trend associated with the poorly understood Sebree Trough, a supposed Late Ordovician paleobathymetric low related to the coeval Taconic Orogeny. To explore relationships amon Lexington-Trenton carbonates, Point Pleasant-Utica shales, and the presumed Sebree Trough, multivariate statistical analysis was used to compare geophysical well logs across the state with well logs referenced to the mineral content of 4 Lexington-Trenton-Point Pleasant-Utica cores. Comparing well-log responses with the mineral content of the reference cores allowed the discernment of 10 electrofacies, keyed to lithofacies in the cores. Software analysis of many other well logs across the state then made electrofacies assignments by comparing well-log responses from the other wells with well-log responses from the reference cores preset into the software. Electrofacies responses were color-coded, mapped in wells at 0.6 m (2 ft) resolution, and used to make section lines and isopach maps of similar electrofacies. Isopach maps and cross sections confirm the presence of the Sebree Trough across Ohio, with trends that parallel existing and projected basement structures. This suggests that the Sebree Trough in Ohio was a bathymetric low, which was, at least in part, controlled by reactivation of basement structures due to far-field Taconic stresses.

GCPAN: A Group Convolution Network with Pixel Attention Mechanism for Remote Sensing Image Super-resolution

Abstract Image super-resolution reconstruction techniques, particularly those based on convolutional neural networks (CNN), have recently been successful in remote sensing image reconstruction. However, as we all known that, there are still two limitations, which limit their performance on several remote sensing tasks. Firstly, most of existing methods usually need a large number of parameters to construct their networks, which make the network difficult to train. Moreover, due to the gradient problem and the data degradation problem caused by large parameters, the model will become inefficient and have heavy computational burden. Secondly, the remote sensing image often contains many high frequency and low frequency information and most existing methods are treat them equally. Aiming at these problems, in this paper, we design a novel group convolution network with a pixel attention mechanism named GCPAN to better recover the details of the remote sensing image. First, we use the group convolution to reduce the parameters and computations by diving the feature maps into some groups, however, that may lost the correlation of different features, which is solved by using the channel shuffle after the group convolution. Second, we design a new attention mechanism (pixel attention mechanism) to capture more important information by assigning different weights to each pixel. All of these operations can improve the discriminative learning ability of the network. Our experiments show that our proposed model outperforms the existing state-of-the-art methods both quantitatively and perceptually.

Checking Reachability Property in Complex Concurrent Software Systems with a Knowledge Discovery Approach

Abstract The model checking technique is a formal and effectual way in verification of software systems. By generation and verification of all model states, it analyses the software systems. The main issue in the model checking of the complicated systems having wide or infinite state space is the lack of memory in generation of all states which is referred to as "state space explosion". The Random Forest algorithm which is capable of knowledge discovery faces the above-cited problem by selecting a few promising paths. In our suggested method, first a small model of the system is developed by the formal language of graph transformation system (GTS). A training data set is created from the small state space. The generated training data set is made available to the Random Forest algorithm to detect and discover the logical relationships existent in it. Then, the knowledge acquired in this way is used in the smart and incomplete exploration of the large state space. The proposed approach is run in GROOVE which is an open source tool for designing and studying the model of graph transformation systems. The results indicate that the suggested method in accordance with the two criteria (average running time and the number of explored states) performs better compared with the other approaches.
Web Based Library Information System At Public Senior High School 1 Tigapanah

Senior High School 1 Tigapanah is a high school located in Mulawari Village, Tigapanah District, Karo Regency. The existing system in the library is still done conventionally, namely by recording a list of members and transactions into a book. The data collection technique used is through survey methods and small interviews with respondents. The results obtained from this study indicate that the positive reinforcement with significant numbers in utilizing the school library comes from the invitation of friends, secondly from the teacher, from parents, from library facilities and finally from the librarian. While the negative reinforcement with significant numbers came from the teacher, the second was from discomfort factors such as stress and boredom, and the last was from the surrounding environmental conditions. In the library system, errors often occur in inputting so that data processing becomes slow and the calculation of fines given to students who are late in returning books to the library is often wrong. In paying attention to these problems, a system is needed that can process the existing transaction processes in the library. The programming languages ​​used are: PHP, HTML, CSS, and JavaScript. With this system, all activities make it easy for the library to process borrowing and returning transactions as well as calculating fines.
