Fixed point results of contractive mappings with altering distance functions in ordered $b$-metric spaces

N. Seshagiri Rao, K. Kalyani, Belay Mituku,
Abstract :
We explore the existence of a fixed point as well as the uniqueness of a mapping in an ordered $b$-metric space using a generalized $(\check{\psi}, \hat{\eta})$-weak contraction. In addition, some results are posed on a coincidence point and a coupled coincidence point of two mappings under the same contraction condition. These findings generalize and build on a few recent studies in the literature. At the end, we provided some examples to back up our findings.

 

The Societal Impact of Education on Citizenship as an Entry Point for Building a Culture of Peace and Tolerance

Marwa Mohammed Ebrahim Almulla,
Abstract :
In this paper, we discuss the impact of promoting the values of harmony, dialogue, equality, brotherhood, freedom, humanity, individualism, justice, pluralism and rationality, as an education aim and one of the most effective means to spread these values. Also, awareness of the rights and freedoms in which the human being participates is considered as an effective tool in confronting the various manifestations of extremism, violence and excluding the different items with rooting civic values in the deepest aspects of human life. It is shown that the culture of nonviolence, non-extremism, and conflict resolution must be spread by peaceful means away from the trends of identity hatred and excessive centering on rejecting the other. On the extent to which learners acquire the principles of living together through a life skills approach, as well as the adoption of an authentic evaluation that transcends the classical assessment that does not exceed the evaluation of knowledge, among its basic principles. Finally, the teacher is called to go beyond the prevailing ideology that considers the school to be an independent space in its own right, and therefore it is necessary to introspect in his educational and pedagogical practices the expectations of the community from the school and the expectations of the educated children from the school.

 

Shrink: An Efficient Construction Algorithm for Minimum Vertex Cover

Wael Mustafa,
Abstract :
The minimum vertex cover (VC) problem is to find a minimum number of vertices in an undirected graph such that every edge in the graph is incident to at least one of these vertices. This problem is a classical NP-hard combinatorial optimization problem with applications in a wide range of areas. Hence, there is a need to develop approximate algorithms to find a small VC in a reasonable time. This paper presents a new construction algorithm for the minimum VC problem. Extensive experiments on benchmark graphs show that the proposed algorithm is extremely competitive and complementary to existing construction algorithms for minimum VC problem.

A. M. Kozae, Mohamed Shokry, Manar Omran,
Abstract :
Millions of people worldwide suffered from lung cancer last year. In this paper, we will build a knowledge-based medicine method and obtain a related prediction system named Fuzzy Soft Expert System and implement a new approach called Intuitionistic Fuzzy Set Expert System. Therefore, in identifying lung cancer disease, we’ll compare these two ways that breakthrough has resulted in a prognostic test suggesting whether or not patients suffer from lung cancer.

Numerical solution of a space-time fractional derivative of groundwater flow equation

ABDON ATANGANA,
Abstract :
The classical Darcy law is generalized by regarding the water flow as a function of a non-integer order derivative of the piezo¬metric head. This generalized law and the law of conservation of mass are then used to derive a new equation for groundwater flow. Two methods including Frobenius and Adomian Decomposition method are used to obtain an asymptotic analytical solution to the generalized groundwater flow equation. The solution obtained via Frobenius method was valid in the vicinity of the borehole this solution was in perfect agreement with the data observed from the pumping test performed by the institute for groundwater study on one of their borehole settled on the test site of the University of the Free State. The test consisted of the pumping of the borehole at the constant discharge rate Q and monitoring the piezometric head for 350 minutes. Numerical solutions obtained via Adomian method are compared with the Barker generalized radial flow model for which a fractal dimension for the flow is assumed. Proposition for uncertainties in groundwater studies was given

 

Detection of Wood Image with Rot Based on BP Neural network

Mu Hongbo,
Abstract :
Wood defect with rot reduces wood quality badly. X-ray is selected to be the testing source for nondestructive testing. The wood images with rot obtained from X-ray were preprocessed and extracted feature. The feature parameters were preprocessed and were input into BP neural network, and then the wood defects can be recognized. The experimental results show that the detection rate can be up to 86% and the performance shows that this method is very successful for detection and classification of wood defects. This study offers a new method for automatic detection of wood defects. It is useful for the scientific selection and effective utilization of wood resources.

 

Research on the Multicast Protection Algorithm Based on QoP+QoS in WDM Networks

Li Du,
Abstract :
Single link failure is the primary form of all kinds of network failures. Protecting survivable multicast sessions against single link failures in WDM networks has been becoming more and more important. Furthermore, measuring and improving the QoS (Quality of Service) and QoP (Quality of Protection) is of great significance to the development of multicast sessions with the enhancement of peoples consciousness of QoP and QoS. This paper studies the multicast protection approaches and algorithms based on QoP+QoS and puts forward some innovative designs. Firstly, we do qualitative and quantitative analyses about QoP+QoS. Secondly, VS_MFBG scheme based on VS (Virtual Source) is presented to save resources. What is more, we innovatively propose SDP_QPS (Shared Disjoint Paths based on QoP+QoS) algorithm. Shown in the simulation results, these designs can not only improve the rate of resource utilization, but also decrease the blocking probability and average delay.

 

Research on Interference Suppression of Pseudo-random Code Phase Modulation Fuse Based on EDTWD Analysis method

Yin Dafeng,
Abstract :
The anti-jamming ability of pseudo-random code phase modulation fuse is very strong. But the effectiveness of suppressing narrow-band interference is limited by the signal bandwidth. Thus, an effective method is developed to identify the narrow-band interference in the wide-band spread spectrum signal. Extended discrete-time Wigner-Ville distribution (EDTWD) analysis method is adopted to extract and reconstruct the narrow-band interference in the received signal of pseudo-random code phase modulation fuse. Then the interference is cancelled by the adaptive interference cancellation. The method doesn’t require any prior knowledge of interference signal, makes the received signal distorted little and can also be used in the circumstance of some interference sources. The simulation result showed that the interference signal after being separated and then synthesized had the similar frequency characteristics as before.

High Variability Resilient in Nano-Scaled Technologies for Low power 7T-SRAM Design

Shyam Akashe, Sanjay Sharma,
Abstract :
High variability in nano-scaled technologies can easily disturb the stability of a carefully designed standard 6TSRAM cell, causing access failures during a read/write operation. We propose a 7T-SRAM cell to increase the read/write stability under large variations. The proposed design uses a low overhead read/write assist circuitry to increase the noise immunity. Use of an additional transistor and a floating ground allows read disturb free operation. While the write assist circuitry provides a floating ground during a write operation that weakens cell storage by turning off the supply voltage to ground path of the cross-coupled inverter pair. This allows a high speed/low power write operation. Monte Carlo simulations indicate a 200% increase in the read stability and a boost of 124% in write stability compared to a conventional 6T-SRAM design, when subjected to random dopant fluctuations, line edge roughness, and poly-granularity variations. HSPICE simulations of a 45nm 64x32 bit SRAM array designed using standard 6T and proposed 7T SRAM cells indicate a 31% improvement in write speed, 30% decrease in write power, read power decreases by 60%, and a 44% reduction in the total average power consumption is achieved with the proposed design.
