Deformable or snake models are extensively used for medical image segmentation, particularly to locate tumor boundaries in brain tumor MRI images. Problems associated with initialization and poor convergence to boundary concavities, however, has limited t... see more

The traveling salesperson problem (TSP) is a very well-known NP-hard combinatorial optimization problem. Many different integer programming formulations are known for the TSP. Some of them are “compact”, in the sense of having a polynomially-bounded numbe... see more

The interaction between the rotor and stator is a major source of high amplitude pressure fluctuation and ?ow-induced vibration in multistage centrifugal pumps. the pressure fluctuation is detrimental to the reliable operation of pumps. The sensitivity of... see more

In this paper, Single-Ended Primary Inductor Converter (SEPIC) fed DC motor is proposed.Soft-switching technique such as Zero-Voltage-Switching (ZVS) and Zero-Current-Switching (ZCS) operation plays a vital role in high voltage applications. Zero-Current-... see more

Single crystal of Pb[(Zn1/3Nb2/3)0.91Ti0.09]O3 (PZN-PT) at the composition of morphotropicphase boundary (MPB) shows a very high electromechanical coupling coefficient, piezoelectriccoefficient, and dielectric constant compared to conventional PZT ceramic... see more

Structure-based virtual screening approaches have the ability to dramatically reduce the time and costs associated to the discovery of new drug candidates. Studies have shown that the true hit rate of virtual screenings improves with the scale of the scre... see more
