High-dimensional complex multi-parameter problems are commonly in engineering, while the traditional approximate modeling is limited to low or medium dimensional problems, which cannot overcome the dimensional disaster and greatly reduce the modelling accuracy with the increase of design parameter space. Therefore, this paper combined Kriging with Cut-HDMR, proposed a developed Kriging-HDMR method based on adaptive proportional sampling strategy, and made full use of Kriging s own interpolation prediction advantages and corresponding errors to improve modeling efficiency. Three numerical tests including coupling test, high-dimensional nonlinear test and calculation cost test were used to verify Kriging-HDMR, and compared with the traditional Kriging and RBF-HDMR in R2, REEA and RMEA measuring the approximate accuracy, results show that the improved Kriging-HDMR greatly reduces the sampling cost and avoids falling into local optima. In addition, at the same calculation cost, when the scale coefficient is 1/2, Kriging-HDMR has higher global approximate accuracy and stronger algorithm robustness, while preserving the hierarchical characteristics of coupling between input variables.

This study was conducted in Homa Bay Sub County, Kenya to explore the adoption of ICT among senior teachers, aged between 45-60 years, in teaching and learning of science. A qualitative research approach using a case study design was employed. Eight secondary school senior teachers of science, 2 females and 6 males, within Homa Bay Sub County were purposefully selected. Semi structured interviews were conducted one-on-one basis followed by classroom observation and document analysis. Analysis of the data revealed that senior teachers of science generally integrate ICTs in planning, assessment and in classroom teaching; however pedagogical preferences and teacher’s workload had an influence on their choice of pedagogy. Subsequently, traditional pedagogy dominated their classroom lessons while ICT partially integrated as complementary to teach specific topics in science. The major factors revealed, that stalled ICT adoption in science teaching among the senior teachers, were insufficient technical support that reduced confidence of ICT integration, scarce practical training on ICT usage, basic expertise level in using ICT and inadequate ICT infrastructures in schools. Nonetheless, the senior teachers of science acknowledged that ICT is convenient and beneficial in teaching and learning. Thus, for increasing ICT integration by senior teachers of science in teaching and learning, it was recommended that the senior teachers of science be exposed to consistent ICT training to be abreast with current ICT knowledge, policies developed for teachers’ preparation and professional development be supportive and emphasize ICT integration in pedagogy.

Despite huge investments of time and money as well as decades of research into classroom methodology, the English proficiency of Japanese students arguably remains less than satisfactory, with recent surveys finding that Japan has fallen significantly behind South Korea, Vietnam, and China. Such results seem to reflect comments heard amongst expatriate instructors of English who work in Japan that express frustration at getting Japanese students to participate. Research has found that it is often the western instructors’ unfamiliarity with Japanese styles of learning and classroom interaction patterns that results in less-than-ideal engagement. The pronounced tendency to instruct students from a view which prioritizes the native speakers cultural assumptions, may in turn be linked to how heavily politicized English education in Japan has been in the post-war era.

Despite the world’s generalized stability, new technologies have affected every aspect of everyday life, from transportation and communication to military capabilities. The new possibilities technologies like Artificial Intelligence have introduced, along with the unexplored aspects they entail, present an unprecedented multi-faceted reality in the military domain. Weaponized technologies are being developed in parallel with defensive capabilities, enabling a race between the two and between the states that engage in relevant research. These novelties raise a new modus operandi on the conventional battlefield and in cyberspace, reshaping the very nature of war. Incorporating AI-enabled offensive technologies in war is followed by unfamiliar benefits, challenges, legal and ethical questions. In this paper, some of the most common AI-enabled technologies used in warfare will be discussed, with relevant case studies and some of the major states’ national developments, all while presentingthe benefits and challenges of integrating cutting-edge technologies in the military sphere.

Hyperbolic tangent (Tanh) activation function is used in multilayered artificial neural networks (ANN). This activation function contains exponential and division terms in its expressions which makes it accurate digital implementation difficult. In this paper we present two different approximation techniques for digital implementation of Tanh function using power of two and coordinate rotation digital computer (CORDIC) methods. A comparative study of both techniques in terms of accuracy of their approximation in hardware costs as well as speed of their implementations on FPGA is also explained.

The task of predicting the acceptance of academic papers is of great significance for novices in the field of dissertation writing. Besides paper texts, most existing models rely on additional information without focusing on the writing style of the paper texts. More importantly, these models make fewer attempts to exploit the interactions and aggregations in the hierarchical structure of the paper text. To address these issues, we propose a novel modular hierarchical model(MHM) to make predictions of paper acceptance. The input to our model is only the original paper, and no other extra information is required. We capture the hierarchical structure of paper texts with three encoders: a WtoS encoder, a StoP encoder, and a paper encoder. To this end, the WtoS encoder uses the pre-trained language model SciBERT to obtain the sentence representation from the word representation. The StoP encoder lets sentences in the same paragraph interact and aggregates them to get paragraph embeddings based on importance scores. The paper encoder does interaction among different hierarchical structures of three modules of a paper text: the paper title, abstract sentences, and body paragraphs. Then this encoder aggregates new representations generated into a compact vector. In addition, the paper encoder models the guiding role of the title and abstract, respectively, generating another two compact vectors. We concatenate the above three compact vectors and additional four manual features to obtain the paper representation. This representation is then fed into a classifier to obtain the acceptance decision. Experimental results on a large-scale dataset show that our model consistently outperforms the previous strong baselines in four evaluation metrics. Quantitative and qualitative analyses further validate the superiority of our model.

This paper aims to show how pedagogy influences the learning process, and how the use of ICT tools has a significant positive impact on enhancing the educational environment. ICT tools are required to be used in the modern era because the current generation is tech-savvy and the use of technological devices is indispensable. The use of e-learning became obvious, especially after the pandemic, which prompted extensive research on the proper use of multiple platforms to achieve the interactive learning that educators desired while being apart. Additionally, incorporating AI into the learning process could have a significant impact on improving learning, as well as ask for a multidimensional transformation of both students and educators. However, the use of AI is not entirely independent because students mindsets need to be changed to help them feel like they are in control of their own learning to make them active participants and active citizens.
