Topologies energy

The main contribution of this paper is to show a new AC/DC converter based on the rearrangement of the flyback converter. The proposed circuit only manages part of the energy and the rest is delivered directly from the source to the load. Therefore, with the new topology, the efficiency is increased, and the stress of the components is reduced. The rearrangement consist of the secondary of the flyback is placed in parallel with the load, and this arrangement is connected in series with the primary side and the rectified voltage source.

This paper proposes a mixed-integer linear programming (MILP) model aiming to optimize the topology of transmission networks considering power loss. The proposed MILP model is converted from the MINLP model using the piecewise linearization technique and precisely linearizing the product of the binary and continuous variables. The objective function of the TNEP problem in this study is to minimize the total cost of the power system, including the investment cost for new transmission lines, maintenance cost, cost related to energy losses loss, and production cost of generators.

This paper illustrates the scheme of integrating of photo-voltaic (PV) system as distributed generation to micro-grid. PV system is integrated to grid with three-level inverter and five-level cascaded H-Bridge inverter to invert the type of supply synchronized to grid. Inverter will be controlled with simple current control strategy. Results were presented for the proposed work considering cases like DG sending only active power and DG injecting both active and reactive power through three-level and five-level inverter topologies.

Understanding protein structure and dynamics is essential for understanding their function. This is a challenging task due to the high complexity of the conformational landscapes of proteins and their rugged energy levels. In particular, it is important to detect highly populated regions which could correspond to intermediate structures or local minima.

A phase one design of a new free energy nano reactor is presented. The design is based on a basically topological interpretation of the Casimir effect as a natural intrinsic property of the geometrical topological structure of the quantum-Cantorian micro spacetime. In particular we view dark energy, Hawking negative energy, Unruh temperature and zero point vacuum energy as being different sides of the same multi-dimensional coin.

Peer-to-peer (P2P) networks existing on a MANET are a natural evolution since both are decentralized and have dynamic topologies. As MANETs grow in use due to the increasing popularity of wireless mesh and 4G networks, it is expected that P2P applications will remain as a popular means of obtaining files. Network coding has been shown as an efficient means of sharing large files in a P2P network. With network coding, all file blocks have the same relative importance.

In this paper electromagnetism (EM) metaheuristic is used for solving the NPhard strong minimum energy topology problem (SMETP). Objective function is adapted to the problem so that it effectively prevents infeasible solutions. Proposed EM algorithm uses efficient local search to speed up overall running time. This approach is tested on two sets of randomly generated symmetric and asymmetric instances.

Mammalian adenylate cyclases are predicted to possess complex topologies, comprising two cassettes of six trans-membrane-spanningmotifs followedbyacytosolic, catalytic ATP-binding domain. Recent studies have begun to provide insights on the tertiary assembly of these proteins; crystal-lographic analysis has revealed that the two cytosolic domains dimerize to forma catalytic core, whilemore recent biochemical and cell biological analysis shows that the two transmembrane cassettes also associate to facilitate the functional assembly and trackingof the enzyme. ...
