Research ArticleOpen accessEvery word in the titleSufficient Descent Condition of the Polak-Ribière-Polyak (PRP) Conjugate Gradient Method without Line SearchAbdelrahman A., KH. I. Osman, Osman O.O. Yousif et al.Nonlinear conjugate gradient methods for unconstrained optimization problems are used in many aspects of theoretical and applied sciences. They are iterative methods, so at any iteration a step length is computed using a method called line search. In most cases, the sufficient descent condition plays an important role to prove the global convergence of a conjugate gradient method. Due to … …Journal of Mathematics and Statistics, Vol. 18, Issue 1 · 14 Mar 2022 · 6,360 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLogic and the Mathematic Model of the Subject-Area Description for Corporate Information SystemsKonstantin Yurievich Maslenikov, Georgiy Ivanovich RevunkovAiming to build and receive a logic-mathematical substantiation and model of the process of constructing the description of any subject area for corporate information systems, the authors divided the subject area for building the system into constituent elements and the relationships between them. Using discrete mathematics methods to the graphs and two-seater predicates of the first order, we built an … …Journal of Computer Science, Vol. 18, Issue 1 · 2 Feb 2022 · 6,580 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConfirmation of Personality Types Using Visual Evoked Potential with User Interface Design StimulusIlham Perdana, Paulus Insap Santosa, Noor Akhmad Setiawan, Supra WimbartiAfter obtaining the consistency of Visual Evoked Potential (VEP) by using a stimulus with data-entry user interface design. This study tries to confirm whether an individual's VEP will be classified according to personality type, which results from the proceeds of conventional personality tests usually carried out by the organization that is the place of this research. The results of this … …Journal of Computer Science, Vol. 17, Issue 11 · 4 Dec 2021 · 6,938 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Design Principles and Patterns on Software Flexibility: An Experimental Evaluation Using Flexible Point (FXP)Muhammad Ehsan Rana, Eddy KhonicaSoftware flexibility is a crucial factor in designing and developing software as it reflects its capability to adapt to changes. It is a topic that has been discussed for a very long time which indicates its importance in software development. However, it is not easy to produce a flexible software design. Design principles provide fundamental concepts in designing good software. … …Journal of Computer Science, Vol. 17, Issue 7 · 31 Jul 2021 · 8,481 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeasibility of Non-destructive and Portable Determination for Carrot Quality based on Acoustic SignalsWangyou Zhang, Mingjin Cai, Qiwei Guo et al.To discuss the feasibility of non-destructive determination method for carrot quality based on the acoustic signal, Pearson correlations between the acoustic eigenvalues and the main compositions of carrot were performed. It indicated that the water content, polysaccharide content and pectin content of carrot were all significantly (P …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 25 May 2021 · 6,344 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBuilding Design Rule for Glass Structures by Persian CurveAbdolrasoul Ranjbaran, Mohammad Ranjbaran, Fatema RanjbaranGlass is being increasingly used as a structural material. Its favorable aesthetic qualities have made it popular with modern designers. Recently glass is used for major structural elements such as beams and columns in modern and innovative architectural applications. High slenderness ratios and brittle behavior in tension contribute to the complexity of stability and ultimate strength analysis of glass structures. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 16 Jan 2021 · 8,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSolving the Robust Design Problem for a Two-Commodity Flow Network with Node FailureNoha Hamdy Radwan, Moatamad Refaat Hassan, Mohamed Eid HusseinThe robust design in a flow network is one of the most important problems. It is defined as searching the optimal capacity that can be assigned to the nodes such that the network still survived even under the node’s failure. This problem is considered NP-hard. So, this study presents a genetic-based algorithm to determine the maximum node capacity for a … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 28 Dec 2020 · 6,593 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Expert Evaluation to Assess the Implementation of Persuasive Design in e-CommerceAmjad Al-mutairi, Majed AlshamariIt has been argued that the use of persuasive design in e-commerce applications has a positive impact on user behavior and on converting browsers into buyers. Effective e-commerce applications successfully gain customers’ trust. Thus, it is important for designers to know how to apply and embed persuasive design models in e-commerce applications. This study aimed to assess the extent to … …Journal of Computer Science, Vol. 16, Issue 10 · 18 Oct 2020 · 6,691 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Heuristic Approach Toward Innovative Tire Re-Design Through Advanced TechnologiesRamundo Fulvio Enzo, Fedele LorenzoIn the field of mobility and road transport, tires are components of a vehicle that play a decisive role in active safety. Monitoring tire conditions can affect different areas: Transport safety, optimization of cycles and maintenance costs and environmental protection. In fact, the tire wear check, possibly through the evaluation of the Remainig Useful Life (RUL), allows to meet many … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 22 Aug 2020 · 7,459 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdsorption and Descaling of Cellucotton and Chitosan-Modified Bentonite for Produced WaterTao Yu, Ying Wang, Chengtun Qu et al.The compatibility of non-identical layers within the water present in the produced oil is poor and ion reactions in the oil mixed with water result in scale formation, thereby having a significant impact on oilfield safety production. In this study, methods for the descaling of produced water from different blocks were studied according to the quality characteristics of the produced … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 18 May 2020 · 6,664 accessesView PDFCite
