The luminescence of the marine dinoflagellate Gonyaulax polyedra shows an endogenous diurnal rhythm. The effect of light during the phase of low luminescence capacity may be observed as an enhancement of luminescence during the subsequent bright phase. During the bright phase, however, illumination diminishes the capacity for luminescence. The action spectra for these two effects of light have ...

In this paper, we propose a high capacity dataembedding system in DCT domain and review the existing high capacity data embedding systems both in spatial domain as well as transform domain. The embedding algorithm is based on the quantized projection embedding method with some enhancement to achieve high embedding rates. The embedding is done on the quantized DCT coefficients using the concept ...

Absorptive capacity generally facilitates the adoption of innovation. How does this relationship change when economic return is not the sole driver of innovation uptake? We investigate whether absorptive capacity facilitates the adoption of green innovation based on a survey of 79 construction companies in Scotland. Based on the results of multiple regression analyses, we confirm that existing ...

Multiuser detection technique has been applied for capacity enhancement in the presence of loading, voice activity, sectorization, inter & intra interference in multicell scenario of third 3G WCDMA system. In CDMA based system, each user transmits a data sequences spreaded by a code. This code is Unique to the mobile station (MS) and base station (BS) on both uplink and downlink. The present pa...

In this paper, an efficient scheduling scheme is proposed to increase the available capacity of VoIP services over Evolved UTRA uplink. On top of the advantages of persistent scheduling, the proposed scheme adaptively share the resources of two VoIP users to get early-termination gain of dynamic scheduler. Through system-level simulations, the performance of the proposed algorithm is evaluated ...

The secrecy capacity of the multi-antenna wiretap channel was recently characterized independently by Khisti and Wornell [1] and Oggier and Hassibi [2] using a Sato-like argument and matrix analysis tools. This note presents an alternative characterization of the secrecy capacity of the multi-antenna wiretap channel using a channel enhancement argument. This characterization is by nature inform...
