One of the significant strategies of the power systems is Economic Dispatch (ED) problem, which is defined as the optimal generation of power units to produce energy at the lowest cost by fulfilling the demand within several limits. The undeniable impacts of ramp rate limits, valve loading, prohibited operating zone, spinning reserve and multi-fuel option on the economic dispatch of practical p...

Bone loss occurs during adulthood in both women and men and affects trabecular bone more than cortical bone. The mechanism responsible for trabecular bone loss during adulthood remains unexplained, but may be due at least in part to a reduced mechanoresponsiveness. We hypothesized that trabecular and cortical bone would respond anabolically to loading and that the bone response to mechanical lo...

In old animals, bone's ability to adapt its mass and architecture to functional load-bearing requirements is diminished, resulting in bone loss characteristic of osteoporosis. Here we investigate transcriptomic changes associated with this impaired adaptive response. Young adult (19-week-old) and aged (19-month-old) female mice were subjected to unilateral axial tibial loading and their cortica...

In this simple note, we attempt to further improve the sparse principal component analysis (SPCA) of Zou et al. (2006) on the following two aspects. First, we replace the traditional lasso penalty utilized in the original SPCA by the most recently developed adaptive lasso penalty (Zou, 2006; Wang et al., 2006). By doing so, adaptive amounts of shrinkage can be applied to different loading coeff...

Multi carrier CDMA (MC-CDMA) combines the CDMA and OFDM technologies together and potentially offers the advantages of both the technologies. In frequency selective channel, the sub-carrier experiences different amplitude and phase. In frequency domain spreading, the frequency diversity is employed but the best of different sub-carrier conditions are not fully exploited. In MC-CDMA the performa...

The need to extract a single audio signal of interest from a multi-source and noisy environment is common across many disciplines. Adaptive beamforming, due to its superior interference rejection and noise suppression, is a preferred processing technique for obtaining high quality audio in noisy environments. In a previous study, we have examined the performance of two classes of adaptive beamf...

We address feasibility of adaptive transmission for rapidly varying fading channels encountered in mobile communication systems. Due to rapid channel variations and the feedback delay, implementation of adaptive transmission in these channels requires accurate prediction of future channel conditions. We describe the design and performance of adaptive transmission methods enabled by the Long Ran...

objectives: the vineland adaptive behavior scale-ii is useful in assessing an individual’s daily functioning. they can be used as an evaluation and diagnostic tool for individuals who are mentally retarded or individuals with other handicaps. methods: to determine the efficacy of vabs in clinical settings, 3 cases with mental retardation and behavioral or emotional problems were evaluated accor...
