A Simulation-Based Process Model Learning Approach for Dynamic Enterprise Process Optimization

A laboratory-scale inkjet printing system was designed for printing polymeric inks with the focus on PEDOT:PSS, a transparent, electrically conductive polymer. PEDOT:PSS inks with 0 and 1 wt. % Surfynol were tested rheologically in elongational and shear flows. A process model is presented and validated for the prediction of flow boundary after the ink exits the nozzle, including drop formation. Process optimization involved establishing a process window related to the voltage waveform, substrate temperature, speed and printed line-overlap, aiming at avoiding satellite drops, “coffee cup” rings, the Rayleigh instability, “stacked printed lines,” and discontinuities in the printed lines or films.

Mengapa pembelajaran kontekstual dapat mengembangkan kemapuan penalaran statistis siswa Sekolah Menengah Pertama? Kemampuan penalaran statistis sangat penting dimiliki oleh siswa Sekolah Menengah Pertama, karena dengan kemampuan penalaranr statistis ini siswa dapat memiliki kompetensi dalam hal: 1) memahami informasi-informasi statistis yang tersurat maupun yang tersirat pada setiap permasalahan yang dihadapi. 2) Pemahaman yang baik terhadap bagaimana cara memilih, menyajikan, mererduksi, dan mempresentasikan data yang akan digunakan untuk menjawab permasalahan yang ada. 3) pemahaman dan penalaran yang baik terhadap proses statistis secara keseluruhan termasuk setiap perhitungan yang terlibat dalam proses tersebut. 4) pemahaman untuk memecahkan masalah secara statistis berdasarkan data yang ada, dan menginterprestasikannya dalam pengambilan keputusan yang dapat berlaku secara umum. Oleh karena itu untuk mengembangkan kemampuan penalaran statistis tersebut harus mempertimbangkan pendekatan pembelajaran yang digunakan untuk siswa Sekolah Menengah Pertama. Model pendekatan pembelajaran yang sesuai untuk siswa Sekolah Pertama salah satunya adalah pendekatan pembelajaran kontekstual (Contextual Teaching and Learning). Pendekatan pembelajaran kontekstual ini mengambil permasalahan-permasalahan dalam kehidupan sehari-hari atau permasalahan yang disimulasikan dengan dialog, diskusi,, tanya jawab, dan representasi. Aktivitas pengajaran kontekstual yang dikembangkan adalah: a) belajar berbasis masalah, b) belajar dengan multi konteks, c) belajar mandiri, d) penilaian otentik, dan e) masyarakat belajar.This article presents a contextual learning what it is and what are its characteristics? What is the statistical reasoning skills? Why contextual learning can develop statistical reasoning Traffic junior secondary students? Reasoning ability is very important statistical owned by junior high school students, because of the ability of these statistical penalaranr students may have competence in terms of: 1) understand the statistical information expressed or implied in any problems faced. 2) A good understanding of how to choose, present, mererduksi, and present data that will be used to address existing problems. 3) understanding and reasoning that both the statistical process as a whole including any calculations involved in the process. 4) understanding to solve the problem of statistically based on existing data, and interpret it in decision-making that can be applied generally. Therefore, to develop the statistical reasoning skills should consider learning approach used for junior secondary students. Model learning approach that is appropriate for school students first one of which is a contextual learning approach (Contextual Teaching and Learning). This contextual learning approach to take problems in daily life or simulated problems with dialogue, discussion ,, question and answer, and representation. Contextual teaching activities developed are: a) problem-based learning, b) learning with multi context, c) self-learning, d) authentic assessment, and e) a learning society.

Deep Learning Model

The capability to rank different potential drug molecules against a protein target for potency has always been a fundamental challenge in computational chemistry due to its importance in drug design. While several simulation-based methodologies exist, they are hard to use prospectively and thus predicting potency in lead optimization campaigns remains an open challenge. Here we present the first machine learning approach specifically tailored for ranking ranking congeneric series based on deep 3D-convolutional neural networks. Furthermore we prove its effectiveness by blindly testing it on datasets provided by Janssen, Pfizer and Biogen totalling over 3246 ligands and 13 targets as well as several well-known openly available sets, representing one the largest evaluations ever performed. We also performed online learning simulations of lead optimization using the approach in a predictive manner obtaining significant advantage over experimental choice. We believe that the evaluation performed in this study is strong evidence of the usefulness of a modern deep learning model in lead optimization pipelines against more expensive simulation-based alternatives.

Unsupervised Deep Learning

Convolutional neural networks (CNNs) have achieved unprecedented success in a variety of computer vision tasks. However, they usually rely on supervised model learning with the need for massive labelled training data, limiting dramatically their usability and deployability in real-world scenarios without any labelling budget. In this work, we introduce a general-purpose unsupervised deep learning approach to deriving discriminative feature representations. It is based on self-discovering semantically consistent groups of unlabelled training samples with the same class concepts through a progressive affinity diffusion process. Extensive experiments on object image classification and clustering show the performance superiority of the proposed method over the state-of-the-art unsupervised learning models using six common image recognition benchmarks including MNIST, SVHN, STL10, CIFAR10, CIFAR100 and ImageNet.

ABSTRACT: International Accounting is one of the subjects in the field of Accounting which is not enough to only be studied conceptually, as well as accounting in general. International accounting requires understanding so that later it can be applied in cases related to international trade transactions. This is because in International Accounting, students must know how accounting standards applied to each country can then be harmonized through the convergence method. In addition, students must also understand the accounting for hedging transactions, the application of transfer pricing and translation. The purpose of this study was to describe the Model Group Investigation (GI) in an effort to improve accounting learning competencies of the students of the University of Bunda Mulia Academic Year 2018/2019. The aim to be achieved in this study is to develop a model of accounting learning package as a strategy that can improve the quality of accounting learning and improve student competency in accordance with the vision and mission of the study program. Data collection methods used in this study are observation methods (through experiments), tests and documentation (questionnaire collection). In the results of this study, there was an increase in student achievement in the accounting learning process with the Group investigation learning model and this positive influence was also strengthened through the choice of the learning approach method of the students.
