Termostat pro biologické experimenty / Thermostat for biological experimentsŠtens, Radovan January 2010 (has links)
Master's thesis deals with a design of the thermostat for biological experiments considering 2l of volume, with capability of setting up required temperature between 20-40 degree Celsius and related accuracy of measurement +/- 1 degree Celsius. Following chapters are one by one described and properly explained from possible ways of measuring temperature to final implementation. Result of the thesis presents necessarily calculations, discussion of module's performance modeling, schematics together with PCB's design and the list of components. Neither the question of software nor possibilities of realization is neglected.

Programovatelný termostat / Programmable Thermoregulator DesignKollár, Tomáš January 2010 (has links)
The aim of the study was to design, build and experimentally verify a programmable thermostat. The main control unit of the thermostat is an ATmega168 microcontroller which communicates via I2C bus with remote MAX6615 chips. They are used to measure temperature with a set of thermistors and control the flow of the hot water in the heating system. This work deals with issues of remote control through the I2C bus, servomotor steering, precision temperature measurement and describes the inner workings of the system. The next chapter includes a proposal for possible extension of the system. The last part contains the manual of the control menu structure and a brief description of the software.

Vzdáleně řízený termostat / Remotely controlled thermostatZávodný, Vilém January 2014 (has links)
The aim of my thesis is to understand the manufactured thermostats and design own thermostat to allow the most basic possibilities classical thermostats plus setup and management via web interface. It is a realization of a small web server that works closely with hardware peripherals. In addition, the web interface is still possible to manage a Web server of TFT LCD screen or applications for smart phone with Android. In addition, the thermostat allows the temperature reading from the BLE modules. All temperatures are continuously stored in a database and graphically processed.

Penetration testing of current smart thermostats : Threat modeling and security evaluation of Shelly TRV and Meross Smart Thermostat / Penetrationstestning av aktuella smarta termostater : Hotmodellering och säkerhetbedömning av Shelly TRV och Meross Smart TermostatLindberg, Adam January 2023 (has links)
As smart homes become increasingly common and concerns over Internet of Things (IoT) security grow, this study delves into the vulnerabilities of smart thermostats. These devices offer convenience but also comes with increased risk of cyber attacks. This study evaluates the susceptibility of the Shelly Thermostatic Radiator Valve (TRV) and the Meross Smart Thermostat to potential threats across various attack vectors – encompassing firmware, network, radio, and cloud – through penetration testing guided by the PatrIoT methodology. Findings reveal four unknown vulnerabilities in the Meross Smart Thermostat and two in the Shelly TRV. These vulnerabilities consist of insecure firmware updates, lack of network encryption, exploitable radio communication, and cloud-related gaps. Recommendations aiming at mitigating the found vulnerabilities include implementing secure Wi-Fi access points for both models during setup, and ensuring strong encryption for the Meross Smart Thermostat’s radio communication. The study contributes to an increased awareness of potential security risks associated with these devices, though the extent of vulnerabilities across all smart thermostat models cannot be definitively concluded. / I takt med att smarta hem blir allt vanligare och med växande medvetenhet om säkerhet för Internet of Things (IoT), undersöker denna studie potentiella sårbarheter hos smarta termostater. Dessa enheter förenklar användares vardag, men ger också upphov till nya cyberhot. Denna studie granskar Shelly TRV och Meross Smart Thermostat för potentiella hot inom attackvektorerna firmware, nätverk, radio och moln, genom penetreringstestning som vägleds av PatrIoT-metodiken. Resultatet är fyra upptäckta sårbarheter i Meross-modellen och två i Shelly Thermostatic Radiator Valve (TRV) inklusive osäkra firmware-uppdateringar, brist på nätverkskryptering, utnyttjbar radiokommunikation och molnrelaterade problem. Rekommendationer med syfte att mitigera de upptäckta sårbarheterna inkluderar att implementera säkra Wi-Fi-åtkomstpunkter för båda modellerna under installationen och att säkerställa stark kryptering för Meross Smart Thermostat:s radiokommunikationen. Studien bidrar till en ökad medvetenhet om potentiella säkerhetsrisker som är förknippade med dessa enheter, även om det inte kan fastställas hur vanligt det är med sårbarheter i smarta termostater

[en] ESPÍRITO DE CORPUS: CREATION OF A MARINE CORPS BILINGUAL LEXICON / [pt] ESPÍRITO DE CORPUS: CRIAÇÃO DE UM LÉXICO BILÍNGUE DO CORPO DE FUZILEIROS NAVAISMARIANA LEMOS MULLER 07 June 2022 (has links)
[pt] Este estudo apresenta uma pesquisa temática envolvendo Terminologia, Estudos de Tradução Baseados em Corpus, Terminologia Computacional e Semântica
Lexical, e tem como objeto de estudo a área do Corpo de Fuzileiros Navais. O objetivo desta pesquisa foi de criar um material terminológico por meio de uma metodologia híbrida de extração de termos desenvolvida a partir de testes com ferramentas
de Extração Automática de Termos (EAT). Assim, buscou-se solucionar tanto problemas tradutórios relacionados à subárea de estudo quanto à detecção e validação
de candidatos a termos em um corpus. Primeiramente, foi realizado um estudo piloto
com o objetivo de avaliar as ferramentas TermoStat Web 3.0 e AntConc 3.5.7. Após
os testes por meio da análise de um corpus paralelo bilíngue, foram selecionadas as
melhores condições identificadas para se obter uma metodologia eficaz de extração
automática de termos aliada à análise humana. Em seguida, essa metodologia foi utilizada para a análise de um corpus bilíngue comparável. Os candidatos a termos extraídos foram então validados pelos critérios de Semântica Lexical propostos por
L Homme (2020) e, em seguida, foram detectados seus equivalentes terminológicos.
Este estudo resultou na criação do léxico bilíngue Espírito de Corpus. / [en] This study presents a thematic research in the Marine Corps area involving
Terminology, Corpus-Based Translation Studies, Computational Terminology and
Lexical Semantics. The objective of this research was to create a terminological material through a hybrid methodology of term extraction developed from tests with
Automatic Term Extraction (ATE) tools. Thus, we sought to solve both translation
problems related to the subarea of study and to the detection and validation of term
candidates in a corpus. First, a pilot study was conducted aiming to analyze two tools
– TermoStat Web 3.0 and AntConc 3.5.7. After the conduction of the tests through
the analysis of a bilingual parallel corpus, the best conditions identified were selected
to obtain an effective methodology of automatic extraction of terms allied to human
analysis. Then, this methodology was used for the analysis of a comparable bilingual
corpus. The term candidates automatically extracted were then validated by the Lexical Semantics criteria proposed by L Homme (2020) and their translation equivalents
were detected. This study resulted in the creation of the bilingual lexicon Espírito de
Corpus.
