A novel Finite Element Controller Map (FECM) method for the speed control of a saturated induction motor (IM) drive is presented in this paper. The newly developed algorithm is based on approximate functions in finite elements, which are expressed according to the nodal values of output response of the IM drive. The map complexity depends on the nodes assigned within a discrete element. The proposed...
Recent years, penetration of distributed generation in the distribution system is one of the most attractive studies along with the creation of retail electricity markets and pressure place on countries to exploit the renewable resources. For exploiting the DG potential, the optimal allocation and sizing of DG are essential. In this paper, a novel Cuckoo Search algorithm is presented for optimal location...
Virtual Private Network or VPN provide secure communication for remote users to access private data over public network. Although security is the main priority, the performance of VPN must also be considered. This paper presented how performance of VPN affected by choosing different encryption algorithms used by VPN devices. Analysis on performance of Windows Vista operating system was evaluated on...
The degree Δ-closest phylogenetic 2nd root problem (ΔCPR2) is an NP-hard problem concerning phylogenetic tree reconstruction from a graph representing the similarities of the species concerned. Here we present an approximation algorithm for this problem for any fixed Δ >; 3. When |V| >; 3Δ - 1, our algorithm yields an approximation ratio of max((Δ-2)/α, 2), where α >; 1 is a constant whose...
This paper presents an intelligent-based sizing algorithm for the design of grid-connected photovoltaic system using evolutionary programming. Evolutionary programming had been used to select the optimal PV module and inverter from pre-developed databases such that the expected technical performance of the design could be maximized. The proposed algorithm, known as evolutionary programming-based sizing...
Presence of similar-duplicate records causes over representation of data. If the database contains different representation of the same data, the result of data mining algorithm will be erroneous. Similar-duplicate detection is a hard task, especially when it is domain independent. To date, there are only a few attempts to tackle the domain independent duplicate detection problem. In this paper, we...
Clustering analysis is an important function of data mining. There are various clustering methods in data mining. Based on these methods various clustering algorithms are developed. A recent approach for clustering analysis is based on ldquoswarm intelligencerdquo. Based on this ldquoswarm intelligencerdquo an algorithm was proposed named ldquoant-cluster algorithmrdquo. However, existing ldquoant...
We consider ad-hoc wireless networks and the topology control problem defined as minimizing the amount of power needed to maintain connectivity. The issue boils down to selecting the optimum transmission power level at each node based on the position information of reachable nodes. Local decisions regarding the transmission power level induce a subgraph of the maximum powered graph Gmax in which edges...
