    Library stories: a systematic review of narrative aspects within and around libraries

    No full text
    Background. Libraries are increasingly trying to communicate the library’s contributions and telling the library stories. Stories can be a component of impact assessment and thus add nuance to an assessment. Evaluations of libraries can include collecting and presenting stories of change, which can serve as evidence in impact assessments. The narrative field allows for many different approaches to a narrative perspective in the study of libraries, but the existing literature provides little overview of these studies

    SBL for Multiple Parameterized Dictionaries

    No full text
    SBL for Multiple Parameterized Dictionaries This repository contains the python-code used in [1]. Included are (i) the code for the proposed sparse Bayesian learning (SBL)-based algorithm, (ii) the code for the newtonized orthogonal matching pursuit (NOMP) algorithm [2] used for comparison, (iii) additional files such as for the generalized subpattern assignment (OSPA) metric [3]. The repositor contains three demo examples (example_.py). The script example_crossing.py reproduces Figure 2 from [1]. Repository structure: |- pySBL/pySBL.py Code for the proposed algorithm |- pyOMP/pyOMP.py Implementation of the NOMP method for comparison |- dictionary_functions.py Implementation of the (parameterized) dictionary functions |- gopsa.py Implementation of the OSPA used to evaluate the results. |- example_radar.py Demo example with a single radar comparing SBL and OMP |- example_multiradar.py Demo Example applying SBL to multiple radars \ example_crossing.py Demo example of two crossing targets (Fig. 2) The code was tested using python 3.13 and numpy 2.2.3.

    GHOST-IoT-data-set

    No full text
    The GHOST-IoT-data-set is a public data-set containing IoT network traffic collected with the deployment of the GHOST's capturing module in a real life smart-home installation, with multiple network interfaces and devices. During the capturing, abnormal functioning of devices has been intentionally triggered, to construct a data-set that enables the development of mechanisms that can conduct behavioral analysis against the activity in the smart-home
