This article investigates the problem of fault detection and reconstruction in direct current microgrids (dc MGs) with nonlinear loads. First, a state-space representation dc MG constant power loads (CPLs) is obtained. The faults components, actuators, sensors system are modeled by using additive terms measurement equations. A novel robust detector then proposed to estimate reconstruct faults. ...

There is controversy in the literature regarding a number of topics related to anterior cruciate ligament (ACL)reconstruction. The purpose of this article is to answer the following questions: 1) Bone patellar tendon bone (BPTB) reconstruction or hamstring reconstruction (HR); 2) Double bundle or single bundle; 3) Allograft or authograft; 4) Early or late reconstruction; 5) Rate of return to sp...

In this paper we study the problem of consistency in distributed storage systems relying on erasure coding for efficient fault-tolerance. We propose QLOC - a flexible framework supporting warm data, i.e., data which, while not being very frequently use, nevertheless continues to be accessed reads or writes regularly. builds upon (1) generic family local reconstruction codes with guarantees term...

introduction: motion of the patient during myocardial perfusion spect could potentially results in false perfusion defects. the effect of different reconstruction methods on these artifacts is not studied. clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. this study...

<p><span lang="EN-GB">This paper proposes a fault diagnosis scheme applied to wind turbine system. The technique used is based on modified sliding mode observer (SMO), which permits the reconstruction of actuator and sensor faults. A benchmark with real sequence speed exploited validate proposed detection scheme. Rotor speed, generator blade pitch angle, torque have different orders...
