Fuzzy logic controller and game theory based distributed energy resources allocation
2020
Energy management and demand control through conventional energy generation sources are challenging for energy providers. Distributed energy resources (DERs) allocation near load centers may provide a suitable solution. The main contribution of the paper improves the voltage profile and reduce the active and reactive power losses in the distribution network. DERs are integrated with IEEE 33 bus system using fuzzy logic controller (FLC) and game theory for two different cases with unity and 0.9 power factor (PF) and compares with conventional methods of integration (i.e., modified novel method, power loss sensitivity method, voltage sensitivity analysis method). The capacity of DERs is optim…
Determination of 60 Migrant Substances in Plastic Food Contact Materials by Vortex-Assisted Liquid-Liquid Extraction and GC-Q-Orbitrap HRMS
2021
A GC-HRMS analytical method for the determination of 60 migrant substances, including aldehydes, ketones, phthalates and other plasticizers, phenol derivatives, acrylates, and methacrylates, in plastic food contact materials (FCM) has been developed and validated. The proposed method includes migration tests, according to Commission Regulation (EU) 10/2011, using four food simulants (A, B, C, and D1), followed by vortex-assisted liquid–liquid extraction (VA-LLE) and GC-Q-Orbitrap HRMS analysis in selected ion monitoring (SIM) mode, with a resolving power of 30,000 FWHM and a mass accuracy ≤5 ppm. The method was validated, showing satisfactory linearity (R2 ≥ 0.98 from 40 to 400 …
Evolution and systematics of the late miocene spanish Giraffidae (Mammalia, Ruminantia, Pecora)
2017
Esta tesis doctoral se centra en la filogenia y sistemática de los jiráfidos del Mioceno tardío español (Mammalia, Ruminantia, Pecora). Los jiráfidos son un grupo monofilético de rumiantes caracterizados por la presencia de caninos bilobulados y un tipo especial de apéndice craneal epifisario y permanente denominado osicono [1]. Asimismo son los únicos supervivientes del clado Giraffomorpha, un grupo de rumiantes pécoras que contiene a Propalaeoryx junto con los Palaeomerycidae, Prolybitheriidae, Climacoceratidae y Giraffidae [2,3].Actualmente la familia Giraffidae está representada por tan solo dos géneros actuales africanos, Okapia, con una única especie, Okapia johnstoni, que habita las …

Influenze tra processo ed esiti: alleanza, coesione e cambiamento in un gruppo terapeutico a lungo termine
2012
Questo lavoro esplora, in un gruppo terapeutico con pazienti gravi, due tra le variabili di processo più indagate nelle terapie di gruppo, l’alleanza terapeutica e la coesione, analizzandone le associazioni con gli esiti del trattamento in termini di sintomi e difese. E’ stato esaminato un gruppo a lungo termine, semi-aperto, a cadenza settimanale. L’osservazione si è svolta per un periodo di 18 mesi, per un totale di 50 sedute. Sono stati monitorati 11 soggetti che riportavano diverse diagnosi nell’Asse I e II del DSM IV. TR Gli strumenti di esito usati sono stati l’SCL-90: Symptom Check List; l’ OQ-45: Outcome Question-naire 45.2; e il DSQ: Defense Style Questionnaire. Mentre per rilevare…
Chemical Composition of the Essential Oil of the New Cultivars of Lavandula angustifolia Mill. Bred in Ukraine
2021
Lavender, otherwise known as Lavandula angustifolia Mill., is widely used in landscaping, and its oil is a valuable raw material used in many industries. Therefore, new varieties of this plant are bred. The essential oil composition obtained from fresh flowers of thirteen new Ukrainian cultivars of L. angustifolia were analysed by GC-MS, and eighty-two components were identified. Linalool and linalyl acetate were principal constituents of all of the samples, and ranged from 11.4% to 46.7% and 7.4% to 44.2%, respectively. None of the studied samples fulfilled the requirements of Ph. Eur. and ISO 3515:2002. The main reason was a high content of α-terpineol (0.5–4.5%) and/or terpinene-4-ol (1.…
Description of movement sensor dataset for dog behavior classification
2022
The description and results of the original investigation are found in: Dog behaviour classification with movement sensors placed on the harness and the collar, Kumpulainen, P., Valldeoriola Cardó, A., Somppi, S., Törnqvist, H., Väätäjä, H., Majaranta, P., Gizatdinova, Y., Antink, C. H., Surakka, V., V. Kujala, M., Vainio, O. & Vehkaoja, A., Aug 2021, In: Applied Animal Behaviour Science. 241, 7 p., 105393. Movement sensor data from seven static and dynamic dog behaviors (sitting, standing, lying down, trotting, walking, playing, and (treat) searching i.e. sniffing) was collected from 45 middle to large sized dogs with six degree-of-freedom movement sensors attached to the collar and the ha…
Terveydenhuolto ja kyberuhkat
2019
Kyberturvallisuusstrategian vision mukaan Suomen tulee kyetä suojaamaan elintärkeät toimintonsa kyberuhkaa vastaan kaikissa tilanteissa. Terveydenhuolto on yksi elintärkeistä toiminnoista. Terveystoimiala on kyberhyökkäysten top-5-listalla ensimmäisenä. Hyökkäysten keskeisin motivaatio on potilastietojen arvo pimeillä markkinoilla. Vuonna 2015 varastettiin yli satamiljoonaa potilastietoa, jotka sisältävät rikollisille arvokkaita tietoja, kuten luottokorttinumeroita, työnantajatietoja ja sairaushistoriatietoja. Tässä artikkelissa kuvataan terveydenhuoltoon liittyviä kyberuhkia, kyberhaavoittuvuuksia ja toteutuneita kyberhyökkäyksiä kybermaailman eri ulottuvuudet kattaen. Tarkastelussa käytet…

Abstract Soybean DAS‐44406‐6 expresses 5‐enolpyruvyl‐shikimate‐3‐phosphate synthase (2mEPSPS), conferring tolerance to glyphosate‐based herbicides, aryloxyalkanoate dioxygenase (AAD‐12), conferring tolerance to 2,4‐dichlorophenoxyacetic acid (2,4‐D) and other related phenoxy herbicides, and phosphinothricin acetyl transferase (PAT), conferring tolerance to glufosinate ammonium‐based herbicides. The molecular characterisation data and bioinformatics analyses did not identify issues requiring assessment for food/feed safety. The agronomic and phenotypic characteristics revealed no relevant differences between soybean DAS‐44406‐6 and its conventional counterpart, except for pod count, seed cou…
