Distributed generation (DG) will play an important role in future power generation systems, especially in stand-alone applications. Three phase four-leg inverter is a well-known topology which can be used as an interface power converter for DGs. Thanks to the fourth leg to provide the neutral path, the four-leg inverter is able to supply balanced loads as well as unbalanced loads. In this paper...

We study the role neutrino telescopes could play in discovering supersymmetric extensions of the Standard Model with a long-lived stau next-to-lightest superparticle. In such a setup, pairs of staus are produced by cosmic neutrino interactions in the Earth matter. In optimistic scenarios, one can expect several pair events per year in a cubic kilometer detector such as IceCube. We also show tha...

The spleen, since antiquity, is an organ little known in its duties1,3. We conclude that all its physiological role is not known; but what is known, is that it is essential, verified through other means, by post-splenectomy sepsis for example4,5. Anatomical studies developed by Neder, AM7 and Zapala, A.26, guided by DiDio and anatomical dissections by Campos Christo2, guided by Resende Alves22,...

This paper considers the problem of assigning the closed-loop eigenvalues of linear large-scale systems in a desired stable region using decentralized control. A new method for robust decentralized control of the system via eigenstructure assignment of the subsystems is given. Based on the matrix perturbation theory, sufficient conditions for eigenstructure of each isolated subsystem are derive...

The physical mechanism for the amplitude asymmetry of SST anomalies (SSTA) between the positive and negative phases of the Indian Ocean dipole (IOD) is investigated, using Simple Ocean Data Assimilation (SODA) and NCAR–NCEP data. It is found that a strong negative skewness appears in the IOD east pole (IODE) in the mature phase [September–November (SON)], while the skewness in the IOD west pole...

In many machines, where permanent magnets are used, the effects due to cogging torque generated by permanent magnets (PMs) aggravate the output characteristics of the machines. This paper presents the method for reducing cogging torque in surface-mounted permanent magnet synchronous motor (SPMSM). A new cogging torque suppression method called axial pole pairing is proposed. Compared to convent...

An interesting case of nonobstructive lower pole hydronephrosis associated with reflux and simulating a neoplasm is presented and discussed. Advanced hydronephrosis localized to one portion of a duplicated kidney in adults may simulate a renal neoplasm on intravenous pyelogram. Upper pole hydronephrosis is a well-described clinical entity and is prominent in the differential diagnosis of renal ...
