<p>Peminatan penjurusan pada sekolah/madrasah dapat di kalsifikasikan berdasarkan hasil dari nilai akhir USBN, nilai akhir UNBK serta rekomendasi dari guru bimbingan konseling (BK). Peraturan pemerintah no. 64 tahun 2014 menyatakan bahawa siswa di kelas X dapat masuk penjurusan baik di IPA maupun IPS, dan hal ini menjadi tantangan bagi para guru khususnya yang mengajar di bidang IPA, dimana para guru harus memiliki strategi dan model pembelajaran yang dapat mendukung terciptanya proses pembelajaran yang ideal ketika siswa memasuki penjurusan di awal kelas X SMA/Madrasah. Salah satu strategi yang dilakukan adalah dengan menggunakan aplikasi sistem informasi pada pilihan penjurusan, namun penerapannya masih perlu dioptimalkan. Pendekatan yang digunakan dalam Penelitian ini menggunakan metode diskriptif kuantitatif dengan metode pengumpulan data yang didapat dari nilai raport yang difilter menggunakan aplikasi yang sudah berjalan dan nilai ujian nasional. Kemudian hasil tersebut digunakan untuk mengambil data kelas yang memiliki proses dan metode pembelajaran yang ideal. Sehingga dari hasil tersebut dapat digunakan untuk meningkatkan keberhasilan siswa-siswa dalam melakukan pembelajaran khususnya ketika berada pada program penjurusan.</p><p> </p><p class="infkeyWords"> </p>
Machine Learning a Highly Accurate Exchange and Correlation Functional of the Electronic Density
Authors: Dick Sebastian , Fernandez-Serra Marivi 
Published: October 2019

Density Functional Theory (DFT) is the standard formalism to study the electronic structure of matterat the atomic scale. The balance between accuracy and computational cost thatDFT-based simulations provide allows researchers to understand the structural and dynamical properties of increasingly large and complex systems at the quantum mechanical level.In Kohn-Sham DFT, this balance depends on the choice of exchange and correlation functional, which only existsin approximate form. Increasing the non-locality of this functional and climbing the figurative Jacob's ladder of DFT, one can systematically reduce the amount of approximation involved and thus approach the exact functional. Doing this, however, comes at the price of increased computational cost, and so, for extensive systems, the predominant methods of choice can still be found within the lower-rung approximations. Here we propose a framework to create highly accurate density functionals by using supervised machine learning, termed NeuralXC. These machine-learned functionals are designed to lift the accuracy of local and semilocal functionals to that provided by more accurate methods while maintaining their efficiency. We show that the functionals learn a meaningful representation of the physical information contained in the training data, making them transferable across systems. We further demonstrate how a functional optimized on water can reproduce experimental results when used in molecular dynamics simulations. Finally, we discuss the effects that our method has on self-consistent electron densities by comparing these densities to benchmark coupled-cluster results.

Context and Convergence: Some Remarks on the Law and Society Movement
Authors: Friedman Lawrence M. 
Published: October 2019

The law and society movement has grown greatly in recent years. It explores two macro-questions: the sources of law, on the one hand, and the impact of law, on the other. It rejects the orthodox view of “legal science”, but embraces the methods of the social sciences. My own work has, recently, dealt with the issue of legal impact; and has also delved into socio-legal history. Historical study can act as a kind of control group for law and society studies; comparative and cross—cultural studies can perform the same function. Studies of modern legal system demonstrate a high degree of convergence—in an interconnected world, societies share both problems and solutions. Socio-legal studies themselves have converged; and share a common intellectual language.

Influence factors of pop-in in the nanoindentation micromechanical property measurement of gas-bearing shale
Authors: Wang Ligeng , Zhang Yuanzhong , Wu Wensheng 
Published: October 2019

Abstract
Studying the micromechanical properties of gas-bearing shale is very important for understanding it. In the nanoindentation measurement of gas-bearing shale, the load-displacement curve often shows pop-in at the loading stage, namely the change of load is small but the change of penetration depth is large. Pop-in can introduce a large error in the calculation of the mechanical parameter. To investigate the influence factors of pop-in, the maximum load, load rate and sample characteristics have been addressed. The results show that pop-in is related to cracks and pores in the shale. Due to the heterogeneity of shale, pop-in cannot be avoided, but can be reduced by choosing reliable load modes and test parameters. Pop-in can increase the maximum indentation depth and decrease the elastic modulus and hardness. The influence of pop-in on hardness is larger than on the elastic modulus. At a high load rate it is easy to induce pop-in. The influence of the load rate on pop-in is larger than that of the maximum load.
Validation of the dynamic response of the HMA layer in an inverted pavement measured by strain foils

Published: October 2019

Abstract
Strain in pavement caused by traffic loading is a critical driver for various distress mechanisms. In this study, strain foils (SFs) are utilized to measure longitudinal strains at the bottom of a hot mixed asphalt (HMA) layer in an indoor inverted pavement. The validity and reliability of SF-measured strain are investigated through three tests using a heavy vehicle simulator (HVS). The three tests focus on the consistency and stability of strain measured by individual SFs and various SFs installed at similar positions, as well as the consistency of strain measured by SF and an asphalt strain gauge (ASG) at different test speeds, load levels, and loading cycles in an accelerated pavement test (APT). Fast Fourier transform is utilized to filter out interference in the raw SF strain data. Filtered SF-measured strains were converted into ASG-measured strain based on effective gauge lengths. Research results show that converted SF-measured strains did not reveal a significant statistical difference compared with strains simultaneously collected by ASG under different test loads and speeds throughout the APT at 300,000 repetitions. Moreover, individual SF can provide consistent results with the coefficient of variation (CV) less than 3.3 % under different speeds and load levels, and SFs installed at similar positions showed similar average maximum strain variations (MSVs) with a maximum difference of 5.8 %. Moreover, the linear correlations between the average MSV and the test load, as well as the speed further verified the validity of SF-measured strain. It is believed that SF could be a viable alternative for strain monitoring in asphalt pavement.
Determination of the modulus of linearity of acrylic bases and acrylic teeth
Authors: Pavlin Martin , Predan Jožef , Gubeljak Nenad , Ćelić Robert 
Published: October 2019

AbstractDental prostheses are manufactured by synthesizing poly-methyl methacrylate (PMMA) in a cavitation model with incorporated acrylic teeth. For the analysis of stress-strain state in the acrylic base and the artificial acrylic teeth, it is necessary to know the mechanical properties of each material. Today it is possible to find the data on the physical and chemical properties of the acrylic base in literature, but data on the modulus of linearity of acrylic teeth is not available. The paper presents the determination procedure of the linearity of the acrylic base and teeth, by performing separate tensile tests of the acrylic base and compression of a cylindrical sample, which is partly made of an acrylic base and dental acryl. Tests were performed at room temperature under the stroke control of a servo-hydraulic testing machine, while the elongations were measured by digital image correlation (DIC) measurement on the surface of the samples. The tensile mechanical properties of the acrylic base were determined by tensile testing of round bar specimens. The linearity modulus of acrylic teeth was determined by cyclic pressure loading of the cylindrical sample with successive increase in pressure force. The modulus of linearity of the acryl base and acryl dental is determined by partial analysis of the obtained cyclic pressure stress-strain curve. Analysis shows that the stress-strain curves deviated and modulus depended on stress level in the tested specimens.
A Query Language Based on Term Matching and Rewriting
Authors: Zieliński Bartosz 
Published: October 2019

Recent years have seen the emergence of a data-centric approach to business process modelling as an attractive alternative to the dominant task-centric one. This new paradigm requires new tools for effective specification, simulation and validation of data-centric models. In particular, such tools must include support for expressive query and database update languages. Rewriting logic was proposed (and successfully used) as a generic framework for the specification of dynamic systems. However, though relational and other data models can be easily simulated, rewriting systems lack the direct support for first-order queries. In this paper we describe a novel condition and query language (at least as expressive as relational algebra), implemented in the term rewriting language Maude, together with a simple framework for relational transition system specification and simulation. The language is designed to be easy to implement on the top of a conditional rewriting system. Its most interesting feature is that it avoids all problems with variable binding. It works with models founded both on sets and multisets, and the language has linear-like facilities to refer to multiplicities of facts (in the case of multiset-founded models). As an example of the use of our language and simulation framework we reproduce some specifications of business processes from the literature. We also compare several methods for choosing the next action and its input during simulation.
The Effects of Computer-Based Cognitive Rehabilitation on Working Memory in Patients with Parkinson’s Disease: A Systematic Review
Authors: Svaerke Katrine , Niemeijer Miriam , Løkkegaard Annemette 
Published: October 2019

Background: Deterioration of working memory(WM) is a common cognitive deficit in Parkinson’s disease (PD), and severely influences the ability to lead an independent life. Interventions which can delay the impact of WM deficits could positively impact the independence and quality of life of patients. Objective: To evaluate effects of computer-based cognitive rehabilitation (CBCR) on WM in patients with PD. Methods: Pubmed, Embase, Psycinfo and Cochrane Library were systematically searched. Authors of included studies were contacted to detect unpublished data or articles not found by database-search. Broad selection criteria were applied because literature was expected to be limited. Studies were eligible for inclusion if they investigated the effects of CBCR on WM in a sample consisting of at least 50% PD patients, or in which the results of PD patients could be isolated. Studies were further eligible for inclusion in a planned meta-analysis if the effects of the CBCR intervention could be isolated, the CBCR intervention was compared to active or passive control groups consisting solely of PD patients, and the WM outcome measure could be isolated. Results: Only six studies were included despite broad inclusion criteria. Study results were heterogeneous, and the risk of bias in study methodology was either unclear or high. Two studies were eligible for meta-analysis. A meta-analysis was not performed, because these studies used different measures of WM which were not rated as equally valid and reliable. Conclusion: Existing literature is sparse and provides insufficient evidence to conclude if CBCR benefits WM in PD patients.

Published: October 2019

The custom hiring of the Versatile Multi-crop Planter (VMP) is a profitable enterprise for Local Service Providers (LSP) that could improve their household livelihood but the impacts have not yet been assessed in Bangladesh. In this study, we assessed the use pattern and profitability of custom-hiring the VMP, and its impacts on LSPs’ livelihood. A total of 18 LSP were purposively selected from Rajshahi, Thakurgaon, Mymensingh, and Rajbari districts for this study. The study revealed that LSPs effectively utilized VMP and 2-wheel tractor (2WT) for 4-6 months. They earned Tk. 1,42,434 (with incentive on VMP) and Tk. 1,36,134 (without incentive) per year as net income. The average payback periods were 0.72 and 0.98 years with and without incentive, respectively. The annual break-even of a VMP use was 7.79 ha. The LSPs reported a considerable cash (annual income increased by 34.9 %), and capital enhancement, e.g., land holdings (8.3 %), value of livestock (11.2 %), dwelling houses (36.6 %), household furniture (19 %), and modern amenities (45.5 %). The increased incomes from VMP custom hiring were mostly spent on nutritious food, land mortgage-in, and dwellings. The LSPs reported minor challenges such as being unable to use this machine in the wetland condition (61 %), no seating arrangement on the machine during operation in small plots (56 %), long time taken to complete sowing due to narrow planting width per pass (50 %), farmers’ skepticism about the planting machine as it is still new technology (44 %), and lack of skilled drivers (17 %). Financial support and technical assistance should be made available by the government for LSPs and local manufacturers to accelerate greater adoption of the VMP.
