Optimal diluent allocation in production systems with diluent-ESP-lifted wells
No full textIn this research, the author presents the development of a numerical model for production systems (wells and surface flowlines) to determine optimal diluent allocation. The model includes the main inflow performance equations to represent reservoir deliverability, pressure and temperature drop calculations in tubing, electric submersible pump (ESP) modeling including viscosity and frequency correction equations, and oil blending models for the injection module. For the injection module, both ASTM D7152-11 standard and Cragoe (1933) methods are available. For the production fluid modeling, the author considered the black oil model to calculate thermodynamic properties and an emulsion model to calculate fluid viscosity depending on its water cut. The gas phase was neglected. The model was developed by using object-oriented programming (OOP) in a commercial software

Establishing, Implementing and Auditing Linux Operating System Hardening Standard for Security Compliance
No full textRegulatsioonid loovad väljakutseid ettevõtetele, sest nad peavad igal aastal turvavastavuseks täitma turvastandardeid. Turvastandardite mitte järgimine teeb ettevõtted küberohtudele haavatavaks. Antud magistritöö pakub lahenduse, et täita ettevõtte operatsioonisüsteemi tugevdamise nõudeid luues, implementeerides ja auditeerides Linux (Debian) operatsioonisüsteemi tugevdamise turvastandardit. Magistritöö käsitleb tugevdatud virtuaalmasina tõmmise ehitamist Microsoft Azure pilveplatvormile, mis vastab operatsioonisüsteemi tugevdamise standardile. Kuna lihtsalt ettevõtte turvavastavuse nõuete täitmine ei ole piisav, siis tuleb tagada selle auditeeritavus, et turvavastavuse täitmist audiitoritele tõestada. Antud magistritöös on koostatud lahendus, mis automaatselt auditeerib operatsioonisüsteemi tugevdamise standardit ja võimaldab kinnitada erinevusi standardi ja tegelike virtuaalmasinate konfiguratsioonide vahel. Autor on analüüsinud virtuaalmasinate turvavastavust enne ja pärast uue operatsioonisüsteemi tugevdamise standardi rakendamist.Regulations create challenges to the companies as they must meet tough security standards for security compliance every year. Not following security standards are making companies more vulnerable to cyber threats. This paper provides a proof-of-concept solution for being compliant with operating system hardening requirements of the company by establishing, implementing and auditing Linux (Debian) operating system hardening standard. This work will focus on building a hardened virtual machine image for Microsoft Azure platform that is compliant with the hardening standard that is established in this thesis. As it is not enough to just meet the company security compliance requirements, then there is a need to ensure auditability of it, therefore a proof-of-concept solution is built for automatically auditing the operating system hardening standard that continuously allows to validate the gap between the standard and actual configurations on virtual machines. To demonstrate the result, the author analysed virtual machines compliance state before and after implementing the new operating system hardening standard
Driver behavior and monitoring of risk : Damasio and the role of emotions
No full textA key issue involved in driver behavior (and therefore one that should be involved in driver behavior models) is the role of emotions. Recent achievements in neurobiology should also be taken into account. Damasio (author of "Descartes' Error: Emotion, Reason and the Human Brain") distinguishes between emotions, defined as bodily responses and changes caused by external stimuli, and feelings, defined as the conscious experiences of these bodily changes; and argues that the emotions and feelings are the very instruments that make an organism capable of evaluating scenarios and making decisions in any given situation. This paper discusses the model put forward by Damasio and its implications for understanding risk monitoring, processing of information, and decision-making.</p
The Electronic Evidence Examination Reporting System by the Example of West Prefecture
No full textMagistritöös uuriti erinevaid viise eesmärgiga kiirendada elektroonilise asitõendi sisuanalüüsi uurimist vaatlusprotsessis. Muutes politsei tööd elektrooniliste asitõenditega efektiivsemaks, aitab see säästa ka maksumaksja raha, mis on ühiskonnale kasulik. Praegune probleem seisneb pidevas ajapuuduses elektrooniliste tõendite menetlemise protseduuris ja faktis, et vaatlejate kogutud märkmed on üldjuhul korrapäratud. See töö keskendub praktilistele probleemidele, nagu kuidas parandada elektroonilise asitõendi vaatluse protokolli koostamise kiirust. Töös kasutatakse tehniliste uuringute andmeid, mis koguti Lääne prefektuuris ning mis põhinevad tõelisel tööstatistikal ja Politsei– ja Piirivalveameti loal. Loodud andmekogumisemudel võib tagada arvuti vaatleja töö suurema produktiivsuse. Kvantitatiivne ja kvalitatiivne analüüs näitab, et see on kahtlemata üks võimalus kuidas saab kiirendada elektrooniliste asitõendite vaatlusprotsessi. Osana tööst valmistas autor Microsoft Access rakenduse, eesmärgiga aidata ekspertidel vaatlusandmeid koguda. Magistritööst on võimalik järeldada, et andmebaasi kasutamine organiseerimaks vaatlejate märkmeid tõstab nende produktiivsust. Koostatud rakendust saab selle magistritöö tulemusel kasutada elektroonilise asitõendi menetlusprotsessis.The master's thesis examined ways to speed up the examination of electronic evidence content analysis inside the examination process. Making police work with electronic evidence more effective to helping them save time can save taxpayers money and this is good for society. The problem is a constant lack of time during the examination of electronic evidence processing procedure and currently the fact that notes are collected disorderly by the examiners. This work will focus on practical issues like how to improve the speed of drawing up an electronic evidence examination protocol. The work was done basing on examination data results that collected in the West prefecture based on real work statistics and permission by the Police and Border Guard Board. Invented data collecting model can lead examiner to be more productive. Quantitative and qualitative analysis imply that this is definitely one way to speed up electronic evidence examination. As part of the work, the practical Microsoft Access application was developed by the author. We can conclude from the thesis that using the database in order to organize the examiners’ notes will make the examiners’ work faster and more productively. Designed solution can be used in electronic evidence examinations as a result of this thesis
Ionic conductivity in LixTaOy thin films grown by atomic layer deposition
No full textThe material system Li-Ta-O is a promising candidate for thin-film solid-state electrolytes in Li-ion batteries. In the present study, we have varied the Li content x in LixTaOy thin films grown by atomic layer deposition (ALD) with the aim of improving the Li-ion conductivity. The amorphous films were grown at 225 degrees C on insulating sapphire and on conductive Ti substrates using tantalum ethoxide (Ta(OEt)(5)), lithium tert-butoxide ((LiOBu)-Bu-t) and water as reactants. The film composition was determined by time-of-flight elastic recoil detection analysis (TOF-ERDA), displaying an almost linear relationship between the pulsed and deposited Li content. The ionic conductivities were determined by in-plane and cross-plane AC measurements, exhibiting an Arrhenius-type behaviour and comparatively weak thickness-dependence. Increasing Li content x from 0.32 to 0.98 increases the film conductivity by two orders of magnitude while higher Li content x = 1.73 results in decreased conductivity. A room-temperature conductivity ciRT of similar to 10(-8) S cm(-1) is obtained for a 169 nm thick Li0.98TaOy film. The evolution of conductivity and activation energy suggests a competing effect between the concentration and the mobility of mobile Li ions when more Li are incorporated. The compositional dependence of Li transport mechanism is discussed. (C) 2020 The Author(s). Published by Elsevier Ltd.Peer reviewe
Integrating between-session homework in psychotherapy: A systematic review of immediate in-session and intermediate outcomes.
No full text[Correction Notice: An Erratum for this article was reported in Vol 60(3) of Psychotherapy (see record 2023-99100-002). In the article (https://doi.org/10.1037/ pst0000488), the number of included studies in Figure 2 omitted two studies that were added to the literature synthesis. Therefore, the following has been added to the Reports excluded box in Figure 2: A further two studies were added to the research synthesis by author knowledge. All versions of this article have been corrected.] This article reviews the evidence for between-session homework (BSH) in individual psychotherapy. Whereas previous reviews have demonstrated a positive association between-client compliance with BSH and distal treatment outcomes; here, we pay particular attention to therapist behaviors that may promote client engagement with BSH assessed as immediate (in-session) and intermediate (session-to-session) outcomes, and moderators of these effects. For our systematic review, we identified 25 studies with 1,304 clients and 118 therapists, mostly on cognitive behavioral therapy such as exposure-based treatments with depression and anxiety disorders. A box score approach was utilized to summarize findings. Results for immediate outcomes were mixed but neutral. Results for intermediate outcomes were positive. Presenting a convincing rationale, being flexible in collaboratively designing, planning, and reviewing homework tasks in accordance with the clients’ goals, aligning BSH with the clients’ takeaways from the session and providing a written summary of homework and rationale, are some therapist behaviors that can promote client engagement with BSH. We conclude with research limitations, training implications, and therapeutic practices. (PsycInfo Database Record (c) 2025 APA, all rights reserved
