Farming organic vegetable and crops have grown as a market desiring commodity. Weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. A few chemicals are commonly applied in organic farming. Thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...

We investigate a transportation problem with discontinuous piecewise linear cost function in this paper. The basic feasible solution for the transportation problem, in which flow bounds on edges are uncertain, is obtained by disaggregating piecewise linear cost function. A genetic algorithm is proposed to solve the transportation problem based on the network representation of the basic feasible...

In the simulation of dynamical processes in economy, social sciences, biology or chemistry, the analyzed values often represent nonnegative quantities like the amount of goods or individuals or the density of a chemical or biological species. Such systems are typically described by positive ordinary differential equations (ODEs) that have a non-negative solution for every non-negative initial v...

This paper presents an efficient LDPC-based algorithm for multi-terminal data compression. In our scenario, a codeword sequence is calculated by multiplying a data sequence by a predetermined LDPC matrix. In contrast, the decoder generates a proper reproduction sequence for a codeword sequence using a message passing algorithm. The key result is the discovery that the LDPC coding technique can ...

This paper is motivated by the following two related problems in complex networks: (i) control of cascading failures and (ii) mitigation of traffic congestion. Both problems are of significant recent interest as they address, respectively, the security of and efficient information transmission on complex networks. Taking into account typical features of load distribution and weights in real-wor...
