Research ArticleOpen accessIn the abstractComparing the Empirical and the Theoretical Probability Density of Return in which Variance Obeying Ornstein-Uhlenbeck Process at Indonesian Stock Exchange IDXDwi Satya Palupi, Eduardus Tandelilin, Arief Hermanto, Muhammad Farchani RosyidThe distribution of the probability density of a return index with stochastic volatility has been calculated. Here the stock index is assumed to follow geometric Brownian motion, while the variance is assumed to obey Ornstein-Uhlenbeck process as in Heston model. The distribution of the probability density of the return which is obtained by solving the Fokker-Planck equation of two dimensional … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 17 May 2017 · 7,625 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Wide Scale Classification of Class Imbalance Problem and its Solutions: A Systematic Literature ReviewGillala Rekha, Amit Kumar Tyagi, V. Krishna ReddyIn today’s world, most of the data (real world) is present in imbalanced form by nature. This is because of not having efficient algorithms to put this data (i.e., generated data by billion of internet- connected devices (IoTs)) in respective format. Imbalanced data poses a great challenge to (both) data mining and machine learning algorithms. The imbalanced dataset consists of … …Journal of Computer Science, Vol. 15, Issue 7 · 3 Jul 2019 · 9,372 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Hydrodynamic Conditions on Algal Organism GrowthBingxin Zhong, Zhifu Wang, Weihua Feng, Baoxing HuangThe growth of algal organisms is influenced by hydrodynamics, making it a crucial aspect of algal biology. We summarize recent studies on the impact of hydrodynamics on algal growth, with a specific focus on current velocity. In the past, extensive attention has been paid to the direct effects of impact factors on algal blooms and there is still a certain … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 9 Sep 2024 · 4,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved SVM with Hyperparameter Tuning for Fake News DetectionAtcharaporn Nachaithong, Kittipol WisaengIn today’s digital age, accessing information has become effortless. An abundance of resources is available online, from trustworthy news outlets providing factual information to unverified opinions shared by anonymous individuals. With the advent of modern technology, social media platforms have revolutionized interaction and staying informed, providing instant access to news and information related to a wide range of topics. They … …Journal of Computer Science, Vol. 20, Issue 10 · 28 Aug 2024 · 5,636 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Modeling and Heat-Moisture Transfer Characteristic Analysis of in Situ Thermal Desorption System for Polluted SoilHuijuan Xu, Yanjun Bi, Lijun Gao, Dongxiao MaIn Situ Gas Thermal Desorption (ISGTD) is one of the effective approaches for organic contaminated soil. To investigate the heat-moisture transfer characteristics of soil during the heating process, a radially layered coupled heat-moisture model of the ISGTD system is established. The temperature and moisture distribution along the radial direction of the heat source, as well as the synergistic action of … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 28 Aug 2024 · 4,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Joint Degree Distribution (JDD) in Luby Transform CodesI. Joe Louis Paul, S. Radha, J. RajaLuby Transform (LT) codes, the first realization of rateless codes are widely used in wireless communication mainly for its adaptability to varying channel conditions and its capacity approaching performance. In spite of the above advantages and its simplicity in implementation, LT codes suffer from a bottle neck of premature termination due to the poor design of degree distribution. In this … …Journal of Computer Science, Vol. 11, Issue 1 · 13 Aug 2014 · 7,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractUSE OF COMPUTATIONAL FLUID DYNAMIC TO PREDICT AIRFLOW AND TEMPERATURE DISTRIBUTION IN A RESIDENTIAL BUILDING WITH AN UNDER FLOOR AIR DISTRIBUTION SYSTEMAbd Alnasser Almate A. Ali, Ahmed Cherif Megri, Paul A. Dellenback, Yao YuOur objective is to demonstrate the use of Computational Fluid Dynamic (CFD) in building applications. In particular, CFD has been used for temperature and airflow predictions of building spaces conditioned using Under Floor Air Distribution (UFAD) System. The space used is an instrumented laboratory room (old daycare center) located at the University of Wyoming. The use of the CFD simulation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 11 Apr 2014 · 8,250 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF MARKOV-BERNOULLI GEOMETRIC DISTRIBUTION RELATED TO RANDOM SUMSMohamed Gharib, Mahmoud M. Ramadan, Khaled A.H. Al-AjmiThe Markov-Bernoulli geometric distribution is obtained when a generalization, as a Markov process, of the independent Bernoulli sequence of random variables is introduced by considering the success probability changes with respect to the Markov chain. The resulting model is called the Markov- Bernoulli model and it has a wide variety of application fields. In this study, some characterizations are given … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 31 Mar 2014 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractShortage Level of Matching Kidney and Pancreas Organs for Implant is EstimatedRamalingam ShanmugamOrgan transplants are increasingly done worldwide. The organ donors might be dead or alive. There are legal, ethical, medical and administrative issues to procure organs and to transplant them. However, the donor’s organs must fully match the recipient’s requirement before they are quickly transported as the time is the essence. The kidney or pancreas organs are more in demand. When … …International Journal of Research in Nursing, Vol. 4, Issue 2 · 1 Nov 2013 · 6,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrochemical Supply Chain’s Share in Emission of Green House Gases, Case Study: Shazand Petrochemical ComplexNaser Moharamned, Masoud Aghajani, Faride Atabi, Sahar AzarkamandIn this study petrochemical supply chain shares in global warming is studied by monitoring carbon footprint during manufacturing and distribution phase. For identification and measurement of carbon emissions in petrochemical supply chain, at first step necessary data are collected. Then carbon footprint is calculated in manufacturing process. So GHG is measured during fossil fuel use for chemical productions and electricity … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,029 accessesView PDFCite
