Sediment delivery ratio (SDR) is traditionally defined as the fraction of upland gross erosion that is transported out of a defined area, e.g., a plot or catchment. It is, effectively, an index of sediment transport efficiency. Previously, it is treated as an empirically-lumped parameter used as a mechanism for compensating for sediment deposition within a catchment area. In this paper, we prop...

Software defined radio (SDR) is emerging as a powerful platform for future generation cellular systems, due to its capability to operate conforming to multiple mobile radio standards. Channelizer in an SDR operates at the highest sampling rate and hence a low complexity design is needed for the most computationally intensive part of the SDR receiver. The channel filters in the channelizer extra...

Clearly (1) has an SDR provided that |Ai| > i for all i = 1, · · · , n, in particular an SDR of (1) exists if |A1| = · · · = |An| > n or 0 < |A1| < · · · < |An|. Let G be an additive abelian group and A1, · · · , An its subsets. We associate any SDR (2) of (1) with the sum ∑n i=1 ai and set (4) S({Ai}i=1) = S(A1, · · · , An) = {a1 + · · ·+ an : {ai}i=1 forms an SDR of {Ai}i=1} . Of course, S(A1...

In this paper we describe the LIMSI Spoken Document Retrieval system used in the TREC-9 evaluation. This system combines an adapted version of the LIMSI 1999 Hub-4E transcription system for speech recognition with text-based IR methods. Compared with the LIMSI TREC-8 system, this year’s system is able to index the audio data without knowledge of the story boundaries using a double windowing app...

u t w c M a r m b s r s e v e m bstract. To acquire a high dynamic range (HDR) image of a cene, several low dynamic range (LDR) images acquired from a igital camera with different exposure times are generally fused into ne HDR image to cover the entire dynamic range of the scene. owever, when capturing a scene, the scene dynamic range (SDR) s unknown. Consequently, the exposure times for the LD...

Nowadays there is a lot of wireless communication protocols being used, and this results in a series of difficulties for developers of systems that interacts with devices which can use different communication protocols. Software-defined radios (SDR) aims to solve this problem by using a software-based approach to provide flexibility on the implementation of the protocols physical layer. In this...

PURPOSE To describe inter- and intraobserver reliability of 3D measurements of female pelvic floor structures. MATERIALS AND METHODS Twenty reconstructed MR datasets of primiparas at 6-12 months postpartum were analyzed. Pelvic organ measurements were independently made twice by three radiologists blinded to dataset order. A "within-reader" analysis, a "between-reader" analysis, and the intra...

Software Defined Radio (SDR) technology seeks to solve the problem of multiple incompatible broadcast / telecom standards available in different locations, by having standard specific processing defined in software. This software will be downloaded and run on generic hardware, so that different broadcast / telecom standards can be supported by downloading corresponding software modules. Computi...

In this paper, we present the design of a Software Defined Radio (SDR) architecture that is used for geotagging camera images. In this architecture, only the radio frequency (RF) front-end of the SDR is installed on the camera to reduce the power required for collecting Global Positioning System (GPS) geolocation data. A brief snapshot of the GPS signals is collected when a picture is taken and...
