نموذج رياضي جديد يصف تأثير الضغط الطبقي على مسامية ونفاذية الصخور الرملية والكلسية
Authors: محمد رنا جاسم , نادر د. علي فرحان
Published: May 2021

تعد قياس الخصائص البتروفيزيائية (المسامية والنفاذية) للصخور المكمنية (اللباب) من القياسات المهمة في الدراسات المكمنية ، فهي تعطي صورة واضحة عن انتاجيتها النفطية، وعليه فان دراسة العوامل المؤثرة عليها تعد في غاية الاهمية. احد اهم العوامل التي تؤثر على مقدار مسامية ونفاذية  الصخرة، الضغط الطبقي  الناتج عن وزن الطبقات الارضية. في هذا البحث استخدمنا طريقة الانحدار اللاخطي البسيط لصياغة عدة نماذج تنتمي لثلاث عوائل من الدوال الرياضية (الدالة الاسية، دالة القوى و دالة متعدد حدود)، التي تصف العلاقة بين الضغط الطبقي وبين كل من المسامية والنفاذية مبنية على نتائج مختبرية لقياسات المسامية والنفاذية، بعد ذلك اخضعت هذه النماذج  للدراسة والتحليل والتحقق من صحتها والمفاضلة بينها باستخدام معامل التحديد R2  (الذي يعتبر من اهم المعايير الاحصائية التي تقيس درجة جودة نماذج الانحدار)، ومعايير فيزيائية للوصول الى النموذج الامثل.

جميع نماذج الانحدار اللاخطي البسيط تم صياغتها باستخدام برنامج الرسم Origin8 software. بينت النتائج ان هناك عدة نماذج رياضية ممكن ان تصلح نماذج رياضية تمثل العلاقة ما بين الضغط الطبقي وكل من المسامية والنفاذية للصخور الرملية والكلسية، وذلك لان قيمة معامل التحديد R2 لجميع النماذج الرياضية عاليـــة جدا (R2≥ 98). فللصخور الرملية مثلا، جميع النماذج الرياضية وضحت ابتداء، ان هناك انخفاضا في مسامية الصخور الرملية  بازدياد الضغط الطبقي وان جميعها تعطي سلوك متشابها تقريبا، حيث يبدأ الانخفاض من قيمة ابتدائية 100% لتصل الى %( 95.25 - 94.75) أي بعرض نطاق 0.5 %، عند ضغط يعادل ( ) من الضغط الابتدائي (Pi=300 psi).

بعد هذا الضغط فان سلوك النماذج الرياضية يختلف بشكل كبير، حيث يمكن تقسيم هذا السلوك الى ثلاث أنواع: ارتفاع في المسامية مرة أخرى الى مقدار اكبر من القيمة الابتدائية لها من خلال النموذج متعدد الحدود من الدرجة الثانية. استمرار الانخفاض في المسامية وبشكل بطيء جدا من خلال النماذج  دالة القوى. ثبوت واستقرار المسامية من خلال معادلة الحالة المستقرة (SSE)، وهكذا بالنسبة للنفاذية وللصخور الكلسية. تم اختيار معادلة الحالة المستقرة (SSE) كأمثل نموذج رياضي يصف العلاقة بين الضغط الطبقي وكل من المسامية والنفاذية لعدة اعتبارات منها، العوامل الكيميائية و الخصائص المعدنية للصخور، هجرة الحبيبات الدقائقية وانتقالها من مكان الى أخر بسبب حركة الموائع و ضغط الموائع داخل المسامات، كما ان الزيادة المفرطة في الضغط سوف تؤدي الى نشوء قوى فيزيائية و حدوث تكسرات دقيقة بين مكونات الصخرة، كل ذلك يلعب دورا مهما وأساسي في مقاومة تأثير زيادة الضغط الطبقي، مما ينتج عن ذلك موت مسامات وولادة اخرى جديدة.

Recently, solving the optimization-control problems by using artificial intelligence has widelyappeared in the petroleum fields in exploration and production. This paper presents the stateof-the-art reinforcement-learning algorithm applying in the petroleum optimization-controlproblems, which is called a direct heuristic dynamic programming (DHDP). DHDP has twointeractive artificial neural networks, which are the critic network (provider acritique/evaluated signal) and the actor network (provider a control signal). This paper focuseson a generic on-line learning control system in Markov decision process principles.Furthermore, DHDP is a model-free learning design that does not require prior knowledgeabout a dynamic model; therefore, DHDP can be appllied with any petroleum equipment ordevise directly without needed to drive a mathematical model. Moreover, DHDP learns byitself (self-learning) without human intervention via repeating the interaction between anequipment and environment/process. The equipment receives the states of theenvironment/process via sensors, and the algorithm maximizes the reward by selecting thecorrect optimal action (control signal). A quadruple tank system (QTS) is taken as a benchmarktest problem, that the nonlinear model responses close to the real model, for three reasons:First, QTS is widely used in the most petroleum exploration/production fields (entire system orparts), which consists of four tanks and two electrical-pumps with two pressure control valves.Second, QTS is a difficult model to control, which has a limited zone of operating parametersto be stable; therefore, if DHDP controls on QTS by itself, DHDP can control on otherequipment in a fast and optimal manner. Third, QTS is designed with a multi-input-multioutput (MIMO) model for analysis in the real-time nonlinear dynamic system; therefore, theQTS model has a similar model with most MIMO devises in oil and gas field. The overalllearning control system performance is tested and compared with a proportional integralderivative (PID) via MATLAB programming. DHDP provides enhanced performancecomparing with the PID approach with 99.2466% improvement.

In this paper, an investigation of using corrugated passages instead of circular crosssection passages was achieved in conditions simulate the case in the gas turbine blade coolingusing ANSYS Fluent version (14.5) with Boundary conditions: inlet coolant air temperature of300 K with different air flow Reynolds numbers (191000, 286000 and 382000). Thesurrounding constant hot air temperatures was (1700 K). The numerical simulations was done bysolving the governing equations (Continuity, Reynolds Averaging Navier-stokes and Energyequation) using (k-ε) model in three dimensions by using the FLUENT version (14.5). Thepresent case was simulated by using corrugated passage of 3 m long, internal diameter of 0.3 m,0.01 m groove height and wall thickness of 0.01 m, was compared with circular cross sectionpipe for the same length, diameter and thickness. The temperature, velocity distributioncontours, cooling air temperature distribution, the inner wall surface temperature, and thermalperformance factor at the two passages centerline are presented in this paper. The coolant airtemperature at the corrugated passage centerline was higher than that for circular one by(12.3%), the temperature distribution for the inner wall surface for the corrugated passage islower than circular one by (4.88 %). The coolant air flow velocity seems to be accelerated anddecelerated through the corrugated passage, so it was shown that the thermal performance factoralong the corrugated passage is larger than 1, this is due to the fact that the corrugated wallscreate turbulent conditions and increasing thermal surface area, and thus increasing heat transfercoefficient than the circular case.

Sentiment analysis refers to Natural Language Processing techniques that are classified as Unsupervised Learning to identify positive, negative, or neutral opinions. Many of these opinions come through Twitter, because social media is quite effective and efficient in commenting because it can only write a maximum of 140 characters. From previous research, the value of the accuracy of the sentiment analysis carried out by one of the NLP libraries, namely TextBlob, has shown that Unsupervised Learning does not produce such good scores. With the Telkomsel service case study the writer took the dataset from Twitter and the results of the analysis with TextBlob only showed a value of 58.59%. Optimization is done by adding the Support Vector Machine method which is included in the Supervised Learning category. The best results obtained from this study are values that show 75%.

Sistem informasi merupakan suatu tatanan yang terdiri atas organisasi, prosedur, himpunan data dan sumber daya manusia yang mampu menghasilkan dan menyajikan informasi yang akurat dan efektif untuk mendukung berbagai upaya dan pengelolaan data dalam rangka mewujutkan peningkatan dan pertumbuhan instansi atau perusahan pada bidangnya masing-masing.

Dimana masing-masing pegawai kantor tersebut dapat mengajukan cuti sesuai peraturan yang sudah ditetapkan oleh perusahan seperti cuti tahunan, cuti nikah dan cuti melahirkan serta cuti haji dengan ketentuan jumlah hari cuti (waktu masa cuti) seperti dibawah ini :

Cuti Tahunan memiliki waktu masa cuti yang disesuaikan  dengan masa kerja pegawai seperti : Masa kerja 1-5 tahun sebanyak 12 hari kerja dalam setahun, Mada kerja 5-10 tahun sebanyak 15 hari kerja dalam setahun, Masa kerja 10 tahun dst sebanyak 18 hari kerja dalam setahun.

Cuti Nikah memiliki waktu masa cuti sebanyak 3 hari kerja.

Cuti Melahirkan memiliki waktu masaa cuti sebanyak 3 bulan.

Cuti Haji memiliki waktu masa cuti sebanyak 40 hari.

Dimana setiap data pengajuan cuti karyawan pada masing-masing kantor cabang pembantu dan karyawan kantor cabang utama direkap kedalam Microsoft excel dan setiap formulir permohonan cuti masih direkap secara manual. Dengan keadaan seperti gambaran diatas maka tidak menutup kemungkinan akan terjadi kesalahan pada proses pendataan dan bahkan formulir dapat hilang. Sehingga karyawan yang sebenarnya mendapat persetujuan cuti, bisa saja tercecer atau hilang dan bahkan dapat digantikan dengan karyawan yang sebenarnya belum bisa mendapat cuti.

Sehingga pada saat ini pengelolaan data permohonan cuti dilakukan secara manual, dimana proses pengiriman formulir dan surat keputusan pengajuan cuti menggunakan sarana email dan via telepon atau sms. Sehingga mengakibatkan kinerja Bag. Unit Umum menjadi lambat serta menghabat pekerjaan yang lainnya, karena semua proses dilakukan oleh Bag. Unit Umum. Sehingga pada saat ini system terkomputerisasi sangat dibutuhkan oleh instansi terkai agar dapat membantu memperkecil kesalahan dan mempermudah, serta mempercepat kinerja Bag. Unit Umum dalam proses pengeloaan data permohonan cuti

Dengan kondisi diatas maka penulis menuangkan inisiatif untuk membuat sebuah system yang mampu memadai semua proses pengelolaan data permohonan cuti dengan menggunakan metode Waterfall dalam perancanganan perangkat lunak yang akan digunakan oleh semua Pegawai dan Bag. Unit Umum. Agar lebih  memudah dan dapat diakses kapan dan dimana saja sistem dirancang berbasis website dan menggunaka SMS Gateway, sehingga notifikasi pemberitahuan langsung dikirim secara otomatis oleh system tersebut pada masing-masing pegawai yang telah melakukan permohonan baik permohonan tersebut disetujui atau ditolak. Dalam perancangan system penulis mengunakan PHP (Programing Hypertext Prepocessor), framework (LARAVEL) dan SMSGateway.ME sebagai media perancangan system.

A field experiment was conducted during the winter season, 2017-2018, at Demonstration Farm of the College of Agricultural Studies, Sudan University of Science and Technology, Shambat, Khartoum State, Sudan. The objective of this experiment was to assess the effect of water intervals on growth and yield of three Chickpea cultivars, namely Atmore, Wad-Hamid and Shendi. Split-plot design was adopted with three replications. The three water intervals treatments were (10, 20 and 30) days which arranged in the main plots and three chickpea cultivars placed in subplot. Plant parameters measured were plant height (cm), number of leaves per plant, number of branches per plant, number of pods per plant, weight of pods per plant (g), number of seeds per pod, weight of seeds per plant (g) and hundred seed weight (g). The results showed that there were significant differences among the treatments in number of leaves, number of branches, number of seeds per pod and hundred seeds weight. However, there were highly significant differences in plant height, number of pods per plant, weight of pods per plant and weight of seeds per plant. Irrigation every ten days gave best results in most of the studied parameters, irrespective to cultivars. The result revealed that no significant differences occur between chickpea cultivars in all parameters measured except in the number of seeds per pod and hundred seeds weight.

A field experiment was carried out during Kharif season of 2010 and 2011 to study the effect of different nutrients treatments on the productivity of rice. Application of NPK with FYM and Zn proved to be superior in recording the highest Photosynthetic rate and Super Oxide Dismutase. Although fertilizers are important for enhancing rice production but excess use of fertilizer cause deterioration of soil quality which ultimately affect crop productivity so it is required to investigate the physiological aspects of rice plant under integrated nutrients. When imbalanced fertilizers doses are given to the rice-wheat cropping system, they showed a considerable decline in crop productivity and soil fertility.

Published: May 2021

This study aims to develop a model of the future of Indonesia’s food consumption up to 2045, using a baseline of food consumption in 2017 and projections to 2025 as milestones, and to draw policy relevance on food and related issues for the next Medium-Term Development Planning of 2020–2024. The projected demand of Indonesian food consumption is built based on the functional relationship between income and food consumption at the baseline using three different scenarios of economic growth: baseline, moderate, and optimistic. Method of Almost Ideal Demand System (AIDS) was implemented to estimate changes of food consumption. Susenas data from 2017 is used as the baseline of food demand model. Susenas data from 1990–2016 is used to analyze selected food consumption trends and the relationship between food consumption, price trends, and income in all 33 provinces of Indonesia. The results show that future food demand in Indonesia is determined by existing demand, income, price and its composition, and various other factors that affect the behavior and trends of consumption. The policy should focus on the balance between demand-side management and supply-side or productivity improvement, as the majority of food production centers are located in Java.

Does Digitalization Increase Economic Growth? Evidence from ASEAN8 Countries
Authors: Raeskyesa Dewa Gede Sidan , Lukas Erica Novianti
Published: May 2021

Digitalization has become relevant nowadays, not only because of the exposure of new technologies but also the consideration of its impact on the economy. In that regard, this study aims to analyze the effect of digitalization on economic growth. This study uses a descriptive analysis of the eight ASEAN middle-income countries from 1999 to 2014 as well as panel regression analysis with the dependent variable of GDP per capita growth and independent variables of physical capital, human capital, and ICT indicators. As a result, ICT indicators have a significant positive impact on economic growth, along with physical and human capital. The usage and intensity of ICT have a higher impact than access to ICT. Furthermore, human capital contributes the most among the other variables. We recommend the countries invest more in human capital to utilize ICT because it is the quality of human capital that matters to navigate the era of the digital economy.

“As bad as anybody else”: The Innocents, Political Violence, and the Creole-Italian Alliance in Reconstruction New Orleans
Authors: Cook Christopher Joseph
Published: May 2021

Coordinated, violent political attacks increased throughout the months leading up to the 1868 presidential election in New Orleans and the surrounding area. Among the various Democratic organizations involved in election campaigning and voter intimidation, the group that received the lion’s share of credit for political attacks was the Innocents. The Innocents were a multi-lingual organization, made up mostly of Sicilians and other immigrants from modern Italy, but the club was helmed by well-connected Creole gentlemen. This paper explores the alliance between the Innocents’ Creole officers and Italian membership. That New Orleans’s fledgling Italian community found itself at the forefront of coordinated Democratic Party efforts to suppress the black vote calls into question the characterization of this group as non-white: Italian immigrants could support and benefit from white supremacy while continuing to experience prejudice. Such alliances have a history in New Orleans, where before the Civil War the local Know-Nothings held the unusual policy of embracing Catholics and even courting the immigrant vote. Indeed, several former Know-Nothings and their allies can be found among the Innocents’ leadership. Not all of the Innocents supported their organization’s role in the reactionary violence of 1868, and the actions of the club’s liberal members provides interesting complications to the Democratic Party’s courtship of the Italian community in New Orleans. This paper concludes by tracking the Innocents into their next iteration, as the Columbus Legion, and the association between the Democratic Party and Italians in New Orleans through several elections and state constitutional conventions.

This research explores the effect of board characteristics on the timeliness of financial reporting from 2012-2018 for 50 listed financial firms. This research, comprising a survey of 50 companies operating in Nigeria's financial sector, gained insights from the agency theory to investigate the impact of board characteristics on the timeliness of financial reporting. Board characteristics were measured using variables such as board size, board independence, board financial expertise, board diligence and CEO gender. We analysed the data using the logistics regression method. Empirically, the results showed that there is a positive association between the financial experience of the board and the timeliness of financial reporting. The size of the board and the independence of the board indicate a negative relationship to the financial reporting timeliness. While, board diligence revealed a negative and insignificant association with the timeliness of financial reporting. Overall, this indicates that Nigerian financial firms' board characteristics have a bigger effect on the timeliness of financial statements. This study contributes to the literature in emerging economies in the field of corporate governance and financial reporting.
