This work aimed at investigating the performances of different discriminators used in a Delay Lock Loop (DLL) in a multipath environment. A filter based on rake receiver module is proposed to overcome the distorsions caused by reflected rays of the incoming signal. Experimental results confirm the effectiveness of the proposed method.

A flexible software based platform for number plate recognitions applications is described. It breaks the processing into several explicit modules, with the implementation for each module provided by a software plugin using a DLL interface. The modular structure greatly facilitates the comparison between different algorithms for a particular step, and allows code to be reused between applications.

SUMMARY The signaling specificity conveyed by distinct combination of NOTCH receptors/ligands has remained elusive. In this issue of Cancer Discovery, through the development of ligand-specific NOTCH inhibitors, Kangsamaksin and colleagues uncovered unique signaling outcomes downstream of DLL- and JAG-receptor activation and demonstrated their effects in the suppression of tumor angiogenesis.

Abstract. Radial diffusion has been established as one of the most important mechanisms contributing to both acceleration and loss relativistic electrons in outer radiation belt, well supply particles inner belt. In framework “SafeSpace” project, we have used 9 years (2011–2019) multi-point magnetic electric field measurements from THEMIS A, D E satellites create a database radial coefficients ...

The discovery of genetic mechanisms that can transform a morphological structure from a plesiomorphic (=primitive) state to an apomorphic (=derived) one is a cardinal objective of evolutionary developmental biology. However, this objective is often impeded for many lineages of interest by limitations in taxonomic sampling, genomic resources, or functional genetic methods. In order to investigat...

In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...

Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...
