A mathematical model for Solving Integer Linear Programming Problems
A suggested algorithm to solve fully rough integer linear programming (FRILP) problems, is introduced in this paper in order to find rough value optimal solutions and decision rough integer variables, where all parameters and decision variables in the constraints and the objective function are rough intervals (RIs). In real-life situations, the parameters of linear programming problem model may not be defined precisely,...

An Illustrative And Provable Speedy Rsa Decryption Process
In a bid to provide an effective way of providing confidentiality, researchers have invented a new promising form of encryption called homomorphic encryption to improve the security level and running time of RSA public-key cryptosystem. RSA algorithm is known for its security but execution speed is a demerit. This speed is due to the involvement of large bits of numbers in the three stages of its operations (key...

Person re identification is one of the most challenging field of research, and yet it is very important in computer vision. Due to its challenges it still has many areas which are open for research. It is usually applied to the re identification of a person appearing on one camera as the same person identified previously by another camera on the same camera network. Person re identification is normally applied in security...

The study investigated the impacts of buoyancy force and heat source on a reactive third grade fluid flow within parallel channel. The results obtained for the coupled equations governing the fluid flow which are strongly nonlinear are secured using modified Adomian decomposition method (mADM). The present result is compared with the one in Makinde (2009) where the influence of buoyancy force and heat source were not...

Yelli - a new extraction optimization approach to Frequent 2-itemsets
In this paper, we propose a new optimization approach to the APRIORI reference algorithm (AGR 94) for 2-itemsets (sets of cardinal 2). The approach used is based on two-item sets. We start by calculating the 1-itemets supports (cardinal 1 sets), then we prune the 1-itemsets that are not frequent and keep only those that are frequent (ie those that have the itemsets whose values are greater than or equal to a fixed minimum...

An Application on Weighted Composition Operators on Hardy Spaces
Let ϕ, (ϕ+ε) be closely analytic functions defined on D, such that ϕ(D)⊆D. The operator given by f⟼(ϕ+ε)(f∘ϕ) is called a weighted composition operator. We show the boundedness, compactness, weak compactness, and complete continuity of weighted composition operators on Hardy spaces H_(1+ε) (ε≥0). We show that such an operator is compact on H1 if and only if it is weakly compact on this space. This result depends on a...

On The Action Of Mobile Loads On An Uninterrupted Cylindrical Tunnel
The stationary transport load acts on the surface of the cavity or on the inner surface of the shell reinforcing cavity. The speed of the load movement is assumed to be subsonic, which corresponds to the modern transport speeds in the underground facilities under study. To describe the motion of a half-space and thick-walled shells, dynamic equations of the theory of elasticity in Lamé potentials are used, and for...

An elegant and short proof of Goldbach conjecture
In this paper several methods are examined for proving the Goldbach conjecture. At the preliminary analysis stage a Diophantine equation solution method is proposed for Goldbach partition of a Goldbach number. The proof method proposed however is found to be incomplete since it does not have mechanisms for dealing with the prime gap problem. On the further analysis section some graphical and linear analytical methods are...

Implementing Chiu’s fixed lifetime inventory model
The fixed lifetime inventory system with zero or positive leadtime has being considered by various authors, with the aim of reducing the quantity outdating in the inventory system. Chiu (1995), considered the positive leadtime case by approximating the expected shortage quantity, the expected outdate quantity and the expected on hand inventory. His result was a ordering policy where are the ordered quantity and the reorder...
