Fast Sequence Component Analysis for Attack Detection in Synchrophasor Networks
Modern power systems have begun integrating synchrophasor technologies into
part of daily operations. Given the amount of solutions offered and the
maturity rate of application development it is not a matter of "if" but a
matter of "when" in regards to these technologies becoming ubiquitous in
control centers around the world. While the benefits are numerous, the
functionality of operator-level applications can easily be nullified by
injection of deceptive data signals disguised as genuine measurements. Such
deceptive action is a common precursor to nefarious, often malicious activity.
A correlation coefficient characterization and machine learning methodology are
proposed to detect and identify injection of spoofed data signals. The proposed
method utilizes statistical relationships intrinsic to power system parameters,
which are quantified and presented. Several spoofing schemes have been
developed to qualitatively and quantitatively demonstrate detection
capabilities.Comment: 8 pages, 4 figures, submitted to IEEE Transaction
Patient attitudes to nebulised antibiotics in the treatment of bronchiectasis: a mixed-methods study
Background
Regular daily nebulised antibiotics are widely used in managing bronchiectasis. This patient population typically has severe bronchiectasis requiring multiple other medications. Given that little is known about patients’ views and preferences for such therapies, this was the focus of our study.
Methods
To explore patient lived-experience using nebulised antibiotics, focus groups and semi-structured interviews were conducted with patients and carers; these were audio-recorded and transcribed to enable thematic analysis. QSR NVivo software facilitated data management. The themes developed from the qualitative data analysis were then used to co-design a questionnaire to capture attitudes and preferences towards nebulised therapy. Questionnaires were completed by patients and statistical analysis was performed. Ethical approval was obtained (13/WS/0036).
Results
The study's focus groups comprised 13 patients and carers, and 101 patients completed the questionnaire. Patients described nebulised therapy as an imposition on their daily routine, in turn affecting reported rates of adherence. Results demonstrated that 10% of all patients using nebulised antibiotics found these hard/very hard to administer. Further, 53% of participants strongly agreed/agreed that they would prefer an antibiotic delivered by an inhaler over a nebuliser, if it were as effective at preventing exacerbations. Notably, only 10% of participants wished to remain on nebulised therapy.
Conclusions
Inhaled antibiotics delivered via dry powder devices were deemed quicker and easier to use by patients. Providing they were at least as effective as current nebulised treatments, patients deemed inhaled antibiotics to be a preferable treatment option
