Development of Removable Visual Impact Indicator or Polymer Composite Materials
2021
The prototype of removable visual impact indicator for thermoset polymer composite materials is developed, and its characteristics are experimentally determined. The indicator is a fabric tape glued by epoxy to the surface of the polymer composite. The tape is impregnated with a composition that provides a visual response at the place of an impact on the composite surface. Ball-drop tests demonstrated the increase of the magnitude of the visual response with the impact energy at different substrate hardnesses. The shelf-life and mode of the tape storage until commissioning are determined. Peel tests showed the ability to remove a used indicator without damaging the surface of the composite.

"Co-development of a decision support model for integrated weed management. Metamodelling and sensitivity analysis of a complex mechanistic model (FL…
2018
In order to reduce our use ofherbicides, we need a tool to design weedmanagement strategies relying on fewerherbicides. Weed management is complicatedand, together with necessity of schedulingoperations at long-term and the multiplicity ofcropping system impacts, it explains whymodels are so useful for designing innovativecropping systems. The aim of this thesis is todevelop a decision support system, intended forcrop advisors, reconciling crop protection andecosystem services Our approach consisted inidentifying the structure of the DSS ininteraction with future users while using anexisting research model, FLORSYS, for thebiophysical content of the tool. FLORSYS is a“virtual field” simulat…
High frequency rTMS over the left parietal lobule increases non-word reading accuracy
2012
Increasing evidence in the literature supports the usefulness of Transcranial Magnetic Stimulation (TMS) in studying reading processes. Two brain regions are primarily involved in phonological decoding: the left superior temporal gyrus (STG), which is associated with the auditory representation of spoken words, and the left inferior parietal lobe (IPL), which operates in phonological computation. This study aimed to clarify the specific contribution of IPL and STG to reading aloud and to evaluate the possibility of modulating healthy participants' task performance using high frequency repetitive TMS (hf-rTMS). The main finding is that hf-rTMS over the left IPL improves non-word reading accu…
Anomaly Detection and Classification of Household Electricity Data : A Time Window and Multilayer Hierarchical Network Approach
2022
With the increasing popularity of the smart grid, huge volumes of data are gathered from numerous sensors. How to classify, store, and analyze massive datasets to facilitate the development of the smart grid has recently attracted much attention. In particular, with the popularity of household smart meters and electricity monitoring sensors, a large amount of data can be obtained to analyze household electricity usage so as to better diagnose the leakage and theft behaviors, identify man-made tampering and data fraud, and detect powerline loss. In this paper, the time window method is first proposed to obtain the features and potential periodicity of household electricity data. Combining th…
PAESAGGI IN TRASFORMAZIONE: LA RIGENERAZIONE DEL BACINO MINERARIO DEL NORD PAS DE CALAIS L’iscrizione Unesco e la costruzione della strategia generale
2017
L’attività mineraria, al pari di un evento sismico, rappresenta per il territorio una ferita difficile da rimarginare. I luoghi coinvolti assistono al radicale mutamento dei loro paesaggi, alla trasformazione della loro geografia, alla rottura degli equilibri che per secoli avevano sostenuto la loro economia e società. Questa condizione si aggrava ancor di più a seguito della dismissione delle attività, quando il sistema economico della monocoltura mineraria non costituisce più una risorsa e al suolo rimangono i segni di ciò che era stata l’industria estrattiva. I resti fisici dell’attività industriale iniziano, però, dopo alcuni anni, a esercitare un senso di fascinazione sulla stessa soci…
Inflammatory Biomarkers in Febrile Seizure: A Comprehensive Bibliometric, Review and Visualization Analysis.
2021
Background: Inflammatory markers association with many diseases is the subject of many articles and reviews. This study presents a comprehensive bibliometric review and visualization analysis of inflammatory biomarkers (IB) in the context of febrile seizure (FS) patients. Methods: The study focused on IB in FS using (1) bibliometric analysis specific indicators and maps in order to analyze and present the network of authors, journals, universities, and countries, and (2) automated literature screening and unsupervised clustering approach for filtering and topic cluster identification. Results: We conducted a literature mining search on FS research, specifically IB in the context of FS, usin…
Assessment of the mobility of selected elements in bioleached mining waste from Zloty Stok (Poland)
2017
Different bioleaching processes were applied to mining wastes deposited in the highly polluted post-industrial region - Lower Silesia in Poland. The chemical characterization of the wastes before and after bioleaching processes was performed. The characterisation was based on the distribution of selected elements (Fe, Mn, As, Co, Cr, Cu and Ni) between operationally-defined phases. The phases were defined using a six-step extraction procedure optimised according to the properties of the studied mining wastes. The fractionation and total content of elements in wastes before and after various bioleaching treatments were studied using ICP MS (Inductively Coupled Plasma Mass Spectrometry)and FA…
