Comparison Simulation Analysis of the Gradual Summation of a Function with Recognition of Direct Extrapolation Via IN Series
Full text linkA set of data pattern that have the characteristic of a function can be approached using Newton series simulation. When using the Newton series, the simulation result of the summation of extrapolation data can be gradually done in step by step. However, if using the IN series, the simulation result of the summation of extrapolation data doesnt need to be gradually done in step by step. The methodology in this research compares the data pattern from the simulation results of the high degree function with the results of interpolation and extrapolation from the results of the IN series simulation. Futhermore, will be carried out comparison simulation analysis of the summation of the function values gradually with the extrapolation function directly using the IN series. The result of comparison simulation analysis point out that the value of the total summation of data between the gradual and the direct summation is the same, so that the direct sum technique using the IN Series is able to make the total sum process more efficient
Effective Solutions for Moving Objects in Acceleration Functions and Their Reflections Using Goen's Distance Formula
Full text linkGoen's distance formula effectively calculates the distance from acceleration, which has a pattern as a symmetric function of time changes. In Goen's distance formula, where the acceleration function against time has a symmetric pattern, it can be solved simply by performing a total integral and multiplying it by half of the total time. Symmetric acceleration functions can be constructed by combining certain functions with their reflections. In this study, the method of proving Goen's distance formula is carried out mathematically using single and double-level average integrals of symmetric functions. The advantage of Goen's distance formula compared to the conventional distance formula is that in finding the distance traveled by an object moving with a symmetric acceleration function, it will be more effective because it is sufficient to perform an integral once compared to having to do two integrals as done in the conventional method.Formula jarak Goen adalah formula yang efektif untuk menghitung jarak dari percepatan yang mempunyai pola sebagai fungsi simetri terhadap perubahan waktu. Pada formula jarak Goen dimana fungsi percepatan terhadap waktu berpola simetris dapat diselesaikan cukup dengan sekali integral total kemudian dikalikan dengan setengah dari waktu total. Fungsi percepatan simetris dapat dibangun dari gabungan antara fungsi tertentu dengan cerminannya. Dalam penelitian ini metode pembuktian formula jarak Goen dilakukan secara matematis menggunakan integral rerata bertingkat satu dan dua dari fungsi simetris. Keunggulan dari formula jarak Goen dibandingkan dengan formula jarak konvensional adalah dalam mencari jarak tempuh benda yang bergerak dengan fungsi percepatan simetri akan lebih efektif karena cukup sekali melakukan integral dibandingkan harus dua kali integral seperti yang dilakukan cara konvensional

Analytical Simulation of Linear Comparison of Temperature Changes Versus Time in the Heat Equilibrium Process of Mixing Two Liquids
Full text linkThe explanation of the concept of entropy which explains that the increase in disorder in a closed system that works in advancing time comes from the second Law of Thermodynamics. In its development, Law of Thermodynamics 2 was enriched by the presence of Law of Thermodynamics 2.1 which states that the average entropy process in the forward direction will be the same or smaller than in the backward direction. The meaning of the entropy averaging process in the backward direction is that the entropy averaging process is in the forward direction but works on a heat function that mirrors the previous one, namely the heat function over time in the forward direction. Furthermore, by utilizing the Law of Thermodynamics 2.1, the results of analytical simulations can be seen comparing the level of linearity of changes in temperature over time in the process of heat flow towards thermal equilibrium in the mixing of two liquids. The results of this analytical comparison show one of the benefits of developing the second Law of Thermodynamics, namely Law of Thermodynamics 2.1.Penjelasan konsep entropy yang menerangkan bahwa peningkatan ketidakteraturan pada suatu sistem tertutup yang bekerja dalam waktu maju adalah berasal dari Hukum Termodinamika kedua. Dalam perkembangannya Hukum Termodinamika 2 diperkaya dengan hadirnya Hukum Termodinamika 2.1 yang menyatakan bahwa proses rerata entropy arah maju akan sama atau lebih kecil daripada arah mundurnya. Pengertian dari proses rerata entropy arah mundur adalah proses rerata entropy arah maju namun bekerja pada fungsi kalor cerminan sebelumnya yaitu fungsi kalor terhadap waktu arah maju. Selanjutnya dengan memanfaatkan Hukum Termodinamika 2.1 ini dapat diketahui hasil simulasi analitik perbandingan tingkat kelinieran perubahan suhu terhadap waktu pada proses aliran panas menuju kesetimbangan termal dalam pencampuran dua zat cair. Hasil perbandingan secara analitik ini menunjukkan salah satu manfaat dari adanya pengembangan Hukum Termodinamika kedua yaitu Hukum Termodinamika 2.1
Akurasi dan Fleksibilitas: Perbandingan Metode Konvensional dan Kontinu dalam Pengukuran Koefisien Muai Panjang Logam
Full text linkThis study compares two methods for measuring the coefficient of linear expansion of metals: the Conventional (Discrete) Method and the New (Continuous) Method, focusing on effectiveness, accuracy, and flexibility. Thermal expansion is a crucial phenomenon in materials engineering, and the coefficient of linear expansion is crucial for predicting metal behavior under temperature variations to prevent structural failure. The historically dominant Discrete Method (MD) relies on the linearity assumption and fundamentally requires an initial length (L0) as an absolute reference. This dependence limits flexibility in dynamic experimental situations, where subsequent measurements must reference the original L0. With the development of numerical calculus, the Continuous Method (MC) was developed based on the differential principle, where the coefficient of linear expansion can be calculated from infinitesimal changes in length and temperature without requiring an explicit L0. This approach allows measurements from any point, making it more adaptable for incremental testing. Through numerical simulations on five metals, this study evaluates both methods in two scenarios: an initial measurement of the coefficient of linear expansion and the flexibility of measurements from different temperatures. The results show that both methods produce very close linear expansion coefficient values when measured from the same initial conditions. However, MK proved much more adaptive and efficient, consistently producing valid linear expansion coefficient values without being tied to the original L0. MK can use the length data available at that time as a starting point for subsequent measurements, in contrast to MD, whose results become inconsistent if not referenced to L0. This flexibility of MK is particularly relevant for dynamic material testing and advanced experiments where initial conditions may not always be known or may change. This study presents scientific justification and practical guidance for adopting MK as a more flexible alternative in the thermal characterization of modern materials.Penelitian ini membandingkan dua metode pengukuran koefisien muai panjang logam: Metode Konvensional (Diskrit) dan Metode Baru (Kontinu), dengan fokus pada efektivitas, akurasi, dan fleksibilitas. Pemuaian termal adalah fenomena krusial dalam rekayasa material, dan koefisien muai panjang sangat penting untuk memprediksi perilaku logam di bawah variasi suhu guna mencegah kegagalan struktural. Metode Diskrit (MD), yang secara historis dominan, mengandalkan asumsi linieritas dan secara fundamental memerlukan panjang awal (L0) sebagai acuan mutlak. Ketergantungan ini membatasi fleksibilitasnya dalam situasi eksperimental dinamis, di mana setiap pengukuran lanjutan tetap harus merujuk pada L0 asli. Seiring perkembangan kalkulus numerik, Metode Kontinu (MK) dikembangkan berdasarkan prinsip diferensial, di mana koefisien muai panjang dapat dihitung dari perubahan panjang dan suhu yang infinitesimal tanpa memerlukan L0 secara eksplisit. Pendekatan ini memungkinkan pengukuran dari titik mana pun, menjadikannya lebih adaptif untuk pengujian bertahap. Melalui simulasi numerik pada lima jenis logam, penelitian ini mengevaluasi kedua metode dalam dua skenario: pengukuran awal koefisien muai panjang, dan fleksibilitas pengukuran dari suhu berbeda. Hasil menunjukkan bahwa kedua metode menghasilkan nilai koefisien muai Panjang yang sangat mendekati ketika diukur dari kondisi awal yang sama. Namun, MK terbukti jauh lebih adaptif dan efisien, karena secara konsisten menghasilkan nilai koefisien muai panjang yang valid tanpa terikat pada L0 asli. MK dapat menggunakan data panjang yang tersedia pada saat itu sebagai acuan awal untuk pengukuran berikutnya, berbeda dengan MD yang hasilnya menjadi tidak konsisten jika tidak merujuk pada L0. Fleksibilitas MK ini sangat relevan untuk pengujian material dinamis dan eksperimen lanjutan di mana kondisi awal mungkin tidak selalu diketahui atau berubah. Penelitian ini menyajikan justifikasi ilmiah dan panduan praktis untuk mengadopsi MK sebagai alternatif yang lebih fleksibel dalam karakterisasi termal material modern
INTEREST RATE METRIS SYSTEM: ALTERNATIVE STRATEGY FOR BANKING INDUSTRY
Full text linkThe financial transaction facilities including Automated Teller Machine (ATM), mobile banking, or internet banking can help customers to make real time transactions across location and time zones. On the basis of these two facts, this research comparatively analyze and prove that the daily interest rate system as commonly practiced by the bank potentially create loss to them. Since the daily interest rate system is based on the change of the date, the customers can double the nominal interest rate income. Using comparative analysis, this paper shows that the potential loss may be prevented when the bank use the metris interest rate system, which is based on the time in seconds
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
