Accurate determination of chromosome centromere location is of high importance in cytogenetics, particularly in karyotyping, chromosome classification and determination of exposure to genotoxic environmental effects. This study investigates the ability of CNN to accurately predict the human chromosome centromere location and the effect centering chromosomes in images, by predicted centromere location, has on classification accuracy. Dataset, used to train and test CNN models, contained 8283 annotated individual chromosome images. Prior to performing centromere detection, followed by chromosome classification, the individual chromosome images are preprocessed using sequence of filtering algorithms. The CNN model achieved an average error of 0.5586 and 0.4543 in predicting x and y coordinates of centromere location, respectively. The achieved classification accuracy of randomly oriented and centered chromosomes in images, is 71.10 and 96.73%, respectively. Achieved increase in chromosome classification accuracy of 25.63% highlights importance of chromosome centromere detection, importance of positional variation removal, and high performance of CNN in prediction of centromere location and chromosome classification.

The stakeholders of the cocoa sector should be introduced with determinants that influence an area of cocoa harvest. Objective of the study is to identify the determinants of a harvested area in small cocoa production units in Huila. A correlational method, cross section, and quantitative approach was used with data from the last National agricultural census. Results of the study revealed that major area does not use credit, advice and irrigation increase the area while the organic fertilization is positive. Those displaced by violence have less harvest area and the primary and secondary sectors are positively associated with an increase in area. It can be concluded that the determinants of harvested area identified in this study exhibit a low management behavior in the agronomic practices of cocoa producers that limit the expansion of the harvested area in Huila. This aspect affects the medium and long-term economic sustainability of this agricultural activity. Therefore, continuous training and education of the producers are essential in order to improve this problematic situation.

Asset management in Indonesia still poses problems in terms of securing state-owned property. These concerns make it difficult for analysts to predict laboratory equipment depreciation. Therefore, this research aims to create a new model to address this issue. Additionally, to support laboratory managers in gaining insights, a technology-based framework in the form of a laboratory equipment depreciation prediction model has been developed. A new model has been created in this research, which integrates supervised learning models with linear regression algorithms, and subsequently employs a waterfall system development approach. The testing results of the model for predicting laboratory equipment depreciation showed a high level of accuracy, reaching 93%. Furthermore, the comparison between the prediction model and the laboratory equipment data tested directly by technicians demonstrated an accuracy rate of 100%. Finally, the numerical results demonstrate that our framework provides a valuable solution to the difficulties in predicting laboratory equipment depreciation, offering an innovative and practical approach to laboratory equipment maintenance.

Accountability systems in higher education ensure that academic programs meet learning outcomes and address student cognitive and affective development. The learning outcome assessment is one of the most important elements to enhance and assure the quality of programs. In this paper, we present a “tour” of how an assessment cycle is performed in a national/public university in Qatar. The study draws on “good” practices and how a higher education institution systemizes the process of assessing learning. The approach demonstrates how learning is connected to program objectives and the curriculum through a rational, logical, conceptual, consensual, and interpretable process. Employing specification tables known as curriculum and assessment plan matrices, with tools being assessments and rubrics, learning outcomes measures can be reached. The approach as well as system calls for an institutional structure and organization which place responsibilities on all stakeholders involved in academic programs delivery. The futuristic approach and practice posit a reconceptualization of how students will be assessed, more likely a paradigm shift necessitating a change in practice and trend in which students’ success (achievement) can be based on the learning outcomes attained.

Local polynomial trend models are a special class of state-space models that can be used without having the full information about the process under study, since most of their parameters are embodied in the state vector and estimated immediately. This makes them attractive for use in signal processing. The present work considers problems that arise when using a polynomial model with a local quadratic trend for Bayesian fusion of two humidity sensors. The unknown sensor biases make it impossible for the model to satisfy the observability conditions. There is currently no general solution to this problem. To overcome this difficulty, an approach is presented where the humidity measurement result implicitly includes the bias of one of the sensors. The results of the study can be used to fuse quantities other than humidity when two or more sensors are available.

Teaching in engineering education using Genetic Algorithms (GAs) toolbox as a teaching tool in engineering education can be an effective approach, particularly in Signal Processing subjects, as it encourages students to learn how to find optimal values required in designing digital filters. This research investigates the use of GAs for teaching digital filter design, where the evaluation function of the problem is optimized using Gas. The GAs toolbox simulation is designed to yield a stable, lowest-order H[z] that meets the tolerance parameters and satisfies the design criteria. Teaching GAs involves representing the filter design problem in a way that can be accepted by genetic programming.

Developing the communication skills of software engineering graduates to meet industry requirements is a challenge for educators. This study presents a project-based learning framework that promotes students’ communication skills in a software engineering project course. The questionnaire on self-efficacy for software development (CSESD) was designed for students’ self-assessment of their confidence in communication skills. Findings indicate that students’ CSESD increased significantly after the course ended. Educators can apply the designed framework to software development-related project courses. The CSESD questionnaire can be used to assess students' confidence in their communication skills and assist educators in preparing students’ readiness before graduation.

The Environmental Kuznets Curve provides a conceptual and empirical tool to discuss the relationship between economic development and environmental deterioration in the advancement of the study of the Anthropocene. The analysis is performed using World Bank data from 92 countries with at least 60 interludes and is subjected to a polynomial function model. The results show that the curve is N-shaped for countries with high per capita income. The fulfillment of the turn for Ecuador is related to a trend that can accept the assumption of the Kuznets Environmental Curve. Likewise, the study is limited to the ambiguities in the heterogeneity between countries, therefore, the analysis of the effectiveness of environmental policies, spatial variations and the long-term trend is recommended as future research.
