A strong convergence theorem for a zero of the sum of a finite family of maximally monotone mappings

Abstract: The purpose of this article is to study the method of approximation for zeros of the sum of a finite family of maximally monotone mappings and prove strong convergence of the proposed approximation method under suitable conditions. The method of proof is of independent interest. In addition, we give some applications to the minimization problems and provide a numerical example which supports our main result. Our theorems improve and unify most of the results that have been proved f...

Effect of Zr doping on the structural and electrical properties of spray deposited TiO2 thin films

Abstract: Doping is an effective material re-engineering technique, which provides a possibility of improving properties of materials for different applications. Herein, a Zr-doped TiO2 thin film was deposited applying the chemical spray pyrolysis method and the influence of varying zirconium dopant concentrations on the properties of the film was studied. Morphological studies showed that the Zr–TiO2 films were homogeneous with smaller grain sizes compared to the undoped TiO2 films. As-de...

Halpern–Ishikawa type iterative method for approximating fixed points of non-self pseudocontractive mappings

Abstract: In this paper, we define a Halpern–Ishikawa type iterative method for approximating a fixed point of a Lipschitz pseudocontractive non-self mapping T in a real Hilbert space settings and prove strong convergence result of the iterative method to a fixed point of T under some mild conditions. We give a numerical example to support our results. Our results improve and generalize most of the results that have been proved for this important class of nonlinear mappings.

Algorithm for compressing/decompressing Sudoku grids

Abstract: We describe a way to transfer efficiently Sudoku grids through the Internet. This is done by using linearization together with compression and decompression that use the information structure present in all sudoku grids. The compression and the corresponding decompression are based on the fact that in each Sudoku grid there are information dependencies and so some of the information is redundant.

Thermo-fluidic significance of non Newtonian fluid with hybrid nanostructures

Abstract: The main purpose of this investigation is to analyze the flow and heat transfer behavior of a non Newtonian fluid (Oldroyd B fluid) with hybrid nanostructure subject to externally inclined magnetic field. Cattaneo Christov heat flux model is incorporated in the energy equation. Non linear thermal radiation and viscous dissipation mechanisms are considered. Shooting technique is implemented to accomplish the numerical solution. The outcomes of the numerical computations are discusse...

Fixed points of relaxed (ψ, ϕ)-weakly N-contraction mappings in modular spaces

Abstract: The purpose of this paper is to study the existence and approximation of a common fixed point of a pair of mappings satisfying a relaxed (ψ, ϕ)-weakly N-contractive condition and existence and approximation of a fixed point of a relaxed (ψ, ϕ)-weakly N-contraction mapping in the setting of modular spaces. Our theorems improve and generalize the results in Mongkolkeha and Kumam [23] and Öztürk et. al [26]. To validate our results numerical examples are provided.

A new Lindley-Burr XII power series distribution: model, properties and applications

Abstract: A new generalized class of distributions called the Lindley-Burr XII Power Series (LBXIIPS) distribution is proposed and explored. This new class of distributions contain some special cases such as Lindley-Burr XII Poisson (LBXIIP), Lindley-Burr XII Logarithmic (LBXIIL), Lindley-Burr XII Binomial (LBXIIB) and their sub-models among others. Some structural properties of the new distribution including moments, probability weighted moments, distribution of the order statistics and ent...

Optimal control of the spread of meningitis: in the presence of behaviour change of the society and information dependent vaccination

Abstract: A mathematical model of meningococcal meningitis with incidence dependent self-protection measure and vaccination is formulated and analysed. The vaccination considered is assumed to be given to everyone and is information dependent. It is shown that the disease free equilibrium is globally asymptotically stable, which implies that if the disease reproduction number R0 can be reduced to a value less than unity then it is possible to eradicate the meningococcal meningitis. In additi...

Computational identification of antibody epitopes on the Dengue virus NS1 protein

Abstract: We have previously described a method to predict antigenic epitopes on proteins recognized by specific antibodies. Here we have applied this method to identify epitopes on the NS1 proteins of the four Dengue virus serotypes (DENV1–4) that are bound by a small panel of monoclonal antibodies 1H7.4, 1G5.3 and Gus2. Several epitope regions were predicted for these antibodies and these were found to reflect the experimentally observed reactivities. The known binding epitopes on DENV2 ...

Comparison of vitronectin and fibronectin as substrates during the culture of human embryonic stem cells

Abstract: The feeder free culturing of pluripotent stem cells aims to eliminate the use of mouse embryonic fibroblasts (MEFs) as substrate during in vitro culturing. Here, the potential of fibronectin and vitronectin to keep stem cells undifferentiated was compared using two different stem cell lines (HUES1 and HUES7). Cells were cultured on vitronectin and fibronectin for 3 weeks. Results showed that cells cultured in fibronectin appear to adhere slightly well initially while those in vitro...

Delay bounded multi-source multicast in software-defined networking

Abstract: Software-Defined Networking (SDN) is the next generation network architecture with exciting application prospects. The control function in SDN is decoupled from the data forwarding plane, hence it provides a new centralized architecture with flexible network resource management. Although SDN is attracting much attention from both industry and research, its advantage over the traditional networks has not been fully utilized. Multicast is designed to deliver content to multiple desti...

Security of quantum-key-distribution protocol by using the post-selection technique

Abstract: The post-selection technique was proposed by Christandl, König, and Renner [Phys. Rev. Lett. 102, 020504 (2009)] to simplify the security of quantum-key-distribution schemes. This work applies this technique to derive the security bounds for the six-state Scarani-Acin-Rigbordy-Gisin 2004 quantum key distribution protocol. This protocol can extract secure keys from a source emitting multi-photons due to its robustness from photon number splitting attacks, making it a good candidate...

Comparison of user satisfaction between Text and Virtual Reality Based Expert Systems for diagnosing cattle diseases

Abstract: Even though usability testing of software applications has been studied for decades, little empirical researches have been conducted in Agriculture domain, especially in comparing the usability of none- immersive virtual reality and text based diagnosis expert systems for diagnosing cattle diseases. A quasi -experimental research was conducted in which 62 cattle farmers both commercial and subsistent used either a non-virtual reality based (System A) or a text-based (System B) expe...

Multi-parametric approach for multilevel multi-leader-multi-follower games using equivalent reformulations

Abstract: Multilevel multi-leader multi-follower games address compromises among multiple interacting decision agents within a hierarchical system in which multiple followers are involved at each lower-level unit and more than one decision maker (multiple leaders) are involved in the upper-level. The leaders' decisions are affected not only by reactions of the followers but also by various relationships among the leaders themselves. In general, multiple-leaders multiple-followers (MLMF) game...

Intelligent load balancing techniques in software defined networks : a survey

Abstract: In the current technology driven era, the use of devices that connect to the internet has increased significantly. Consequently, there has been a significant increase in internet traffic. Some of the challenges that arise from the increased traffic include, but are not limited to, multiple clients on a single server (which can result in denial of service (DoS)), difficulty in network scalability, and poor service availability. One of the solutions proposed in literature, to mitigat...
