A longstanding challenge in stream ecology is to understand how landscape configuration organizes spatial patterns of ecosystem function via lateral groundwater connections. We combined laboratory bioassays and field additions a metabolic tracer (resazurin) test groundwater-stream confluences, or “discrete riparian inflow points” (DRIPs), regulate heterotrophic microbial activity along boreal s...

The evolution-based stream clustering method supports the monitoring and change detection of clustering structures. This paper presented HUE-Stream which extends E-Stream and E-Stream++ by introducing a distance function, cluster representation and histogram management for the different types of clustering structure evolution. Compared with UMicro and LuMicro, HUE-Stream produces higher cluster...

This thesis is concerned with the automatic parallelization of real-time stream processing applications, such that they can be executed on embedded multiprocessor systems. Stream processing applications can be encountered in the channel decoding and video decoding domain. These applications typically have real-time requirements. Important trends for stream processing applications are that they ...

This paper shows that the stream models of Nakazawa and Katsumata can be adapted to a typed setting for an extension of the Λμcalculus, called Λμcons. It shows the typed Λμcons is sound and complete with respect to the stream models. It also shows that any individual stream model with whole function spaces and infinite bases characterizes the extensional equality. This result corresponds to Fri...

We present SFINKS, a low-cost synchronous stream cipher for hardware applications with an associated authentication mechanism. The stream cipher is based on a Simple Filter generator, using the INverse function in F216 to generate the Key Stream. The design is based on simple and well-studied concepts, and its security is analyzed with respect to the portfolio of known cryptanalytic attacks for...

An all-optical cryptographic device for secure communication, based on the properties of soliton beams, is presented. It can encode a given bit stream of optical pulses, changing their phase and their amplitude as a function of an encryption serial key that merge with the data stream, generating a ciphered stream. The greatest advantage of the device is real-time encrypting – data can be transm...
