  • Generic Application Programming Interface (API) for Sliding Window FEC Codes
    2019
    Co-Authors: Vincent Roca, Morten Lauge Pedersen, Cedric Adjih, Jonathan Detchart
    Abstract:

    This document introduces a Generic Application Programming Interface (API) for sliding window FEC codes. This API is meant to be compatible with any sliding window FEC code. It defines the core procedures and functions meant to control the codec (i.e., implementation of the FEC code). However, it leaves out all upper layer aspects that are the responsibility of the Application or protocol making use of the codec. As a consequence, this is not an API for a FEC Scheme since certain mechanisms that must be defined by any FEC Scheme (e.g., signalling and FEC Payload IDs) are the responsibility of the caller instead of being addressed by the codec. A first goal of this document is to pave the way for a future open- source implementation of such codes, another goal is to simplify the development of content delivery protocols that rely on sliding window FEC codes for robust transmissions.

  • Rethinking ‘Things’ - Fog Layer Interplay in IoT: A Mobile Code Approach
    2017
    Co-Authors: Behailu Negash, Tomi Westerlund, Pasi Liljeberg, Hannu Tenhunen
    Abstract:

    A client-server architecture style is one of the common approaches enabling separation of concerns in distributed systems. In the Internet of Things architecture, this approach exists in different configuration of sensors, actuators, gateways in the Fog layer and servers in the Cloud. This configuration affects the degree of interoperability, scalability and other functional and non-functional system requirements. In this paper, we reflect on best practices in the web and REST style to address IoT challenges; one of the constraints in REST, Code on Demand, is used for IoT to enhance the flexibility and interoperability of resource constrained clients at the perception layer. Scripts written in a domain specific language, DoS-IL, are organized and stored at the Fog layer for sensor and actuators nodes to request and execute the incoming script. A Generic Application layer protocol and RESTful server are presented along with experimental results.

  • Generic Application of an aqueous two phase process for protein recovery from animal blood
    Process Biochemistry, 2000
    Co-Authors: Marco Ritopalomares, C J Dale, Andrew Lyddiatt
    Abstract:

    The recovery of proteins from animal blood using an established two-stage extraction process was selected as a practical model system to study the Generic Application of polyethylene glycol (PEG)-phosphate aqueous two-phase systems (ATPS). Processing of whole bovine blood in the ATPS two-stage process resulted in the partition of soluble protein (e.g. bovine serum albumin (BSA), haemoglobin, IgG; partition coefficient K=55) into a PEG-rich top phase and cell debris into a phosphate-rich bottom phase. Subsequent back extraction of soluble protein into a second phosphate-rich bottom phase resulted in a maximum overall protein recovery of 62%. The increased protein concentration within the ATPS (from 1.2 to 7.0 mg/g) caused a decreased in the recovery to 44%. Recycling of PEG into the initial extraction stage did not significantly influence the partition behaviour of protein over the equivalent of 20 operational cycles, but protein recovery decreased from 44 to 37%. The extreme conditions (waste material characterised by the presence of solids and impurities) in which the implementation of this ATPS process was tested, confirms the potential for the Generic Application of ATPS for processing complex biological suspensions to achieve a simple primary recovery and partial purification of target protein solutes.
