Syftet med det här examensarbetet är att utreda OPC-standarderna OPC Data Access och motsvarande del i OPC Unified Architecture, samt att implementera OPC-kommunikation i ett system. Behovet av en kommunikationsstandard föddes ur det interoperabilitetsproblem som fanns inom framförallt industriella produktionssystem. Med ett OPC-gränssnitt implementerat mellan en datakälla och applikation kan datautbytet ske på ett standardiserat sätt. OPC Foundation, som är en organisation som tillhandahåller olika OPC-standarder, har idag utvecklat två OPC-standarder, Classic OPC och OPC Unified Architecture. Classic OPC består av ett antal specifikationer som är baserade på COM- och DCOM-gränssnitten, vilket gör att dessa specifikationer är bundna till Windowsplattformen.  OPC Unified Architecture erbjuder ett säkrare och mer mångsidigt kommunikationsgränssnitt än vad Classic OPC-standarden ger, tack vare dess kommunikationsstack. Den praktiska biten i projektet bestod av att implementera OPC-kommunikation i ett system. Två delmoment som ingick i implementeringen var att skapa en testmiljö samt att utveckla en applikation ovanpå klassbibliotek som behandlade kommunikation mot OPC DA- respektive OPC UA-servrar. OPC Unified Architecture-standarden definierar endast formatet på meddelandet innan det kommer fram till kommunikationsstacken. Det här öppnar upp för möjligheten att i framtiden erbjuda kommunikationsstackar som kommunicerar enligt andra protokoll och formateringar, vilket gör att OPC Unified Architecture kommer att kunna anpassas efter framtida behov och på så sätt kommer att vara ett alternativ för interoperabilitet i system under en lång tid framöver. / The purpose of this thesis is to investigate the OPC standard OPC Data Access and the corresponding part in OPC Unified Architecture, and to implement OPC communication in a system. The need for a communication standard was born out of the interoperability problems that existed mainly in industrial production systems. With an OPC interface implemented between a data source and an application, the data exchange can be done in a standardized way. OPC Foundation, which is an organization that provides various OPC standards, has now developed two OPC standards, Classic OPC and OPC Unified Architecture. Classic OPC is a set of specifications that are based on COM and DCOM interfaces, which means that these specifications are tied to the Windows platform. OPC Unified Architecture provides a safer and more versatile communications interfaces than the Classic OPC standard provides, thanks to the communication stack. The practical bit of the project consisted of implementing OPC communication in a system. Two parts that were included in the implementation was to create a test environment and to develop an application on top of the class library that dealt with communication with OPC DA and OPC UA servers. The OPC Unified Architecture standard defines only the format of the message before it reaches the communication stack. This makes it possible to provide communication stacks that communicate according to other protocols and formats in the future, which allowing OPC Unified Architecture to be adaptable to future needs and thus will be an option for an interoperable system for a long time to come.

HMS Industrial networks is a company that offers communication solutions for automation systems. There exists an abundance of different industrial network technologies and HMS manufactures gateways that translate and allow communication between the different networks.The multiplicity of network technologies introduces problems when it comes to monitoring the processes in an automation system. It is desirable to be able to access the process data through a single network technology and this is what OPC UA is used for. Briefly, OPC UA can be described as an interface for exchange ofprocess data in automation systems. HMS has noticed a rising trend in the interest for OPC UA and therefore wants to investigate the possibility to use OPC UA on their platform, the Anybus X-Gateway. The goal of this thesis has been to port an OPC UA stack, provided by the OPCfoundation, to the HMS operating system running on an Anybus X-Gateway. The port has been successful and has been verified by unit tests and a test application. Thus, a first step towards a complete OPC UA product has been taken. Further, the thesis presents a theoretical summary about real-time operating systems to explain their function and usage.

Envirotainer builds containers that are specialized in transporting of temperature sensitive products these containers are customized for airplanes. The containers are then leased to other companies, most often to pharmaceutical companies. Envirotainer are based in Lagga, Knivsta. It is also here where the production of the containers is held. The container RAP T2 was designed in the early 80ies. The RAP T2 contains a fleet of about 1220 containers spread all over the world. This container model needs an update in order to optimize its performance. One of the improvements is achieved by optimizing the UA-value that is too high. A lower UA-value gives the performance of the container more endurance and more stability. Initial testing that was made in the beginning of the project showed that the floor in the container was the biggest stand alone module benefiter of the high UA-value. With that knowledge it was decided that my work should be about the possibility to improve the construction with a new insulation material that would optimize the UA-value. The work started off with an investigation of insulation materials. The most interesting insulation materials were weighted against each other. The result showed that Divinycell was the best insulation material for the design. Then different concepts were made, concept A were the whole floor was redesigned and concept B were an extra insulation module was designed to fit the existing floor. The concepts were weighted against each other in order to choose the final concept. Concept A was the best alternative and was chosen. The concept was then designed in PTC Creo. A prototype was built for UA-value testing. The prototype was then tested and measured against the original container in order to see how much the UA-value was lowered with the new design. And the result of the test showed an improvement of almost 37 %. The UA-value went from 25,40 W/K with the original container design to 16,05 W/K with the prototype design. This shows that an update of the floor design is in order to make the container performance better and more stabile.

Industrial Internet of Things (IIoT) implementeras i snabb takt. Attackytan för cyberhot inom IIoT-nätverk har utvidgats i takt med en mer utbredd användning, och cybersäkerhet för IIoT-enheter har inte varit i fokus. Brister i att upprätthålla säkerhet kan resultera i allvarliga konsekvenser för företag genom bland annat produktionsavbrott, ekonomiska förluster och stöld av affärshemligheter. Arbetets syfte har varit att öka säkerheten för IIoT-nätverk genom att analysera MQTT och OPC UA ur ett säkerhetsperspektiv,  två kommunikationsprotokoll som förekommer inom IIoT-nätverk. Arbetet belyser hur olika nivåer av implementerad säkerhet för MQTT och OPC UA förhåller sig till upprätthållandet av konfidentialitet, riktighet och tillgänglighet. MITC AB är ett företag som bedriver samarbeten med Mälardalens Universitet och Mälardalens industri. MITC AB vill öka kunskapen för cybersäkerhet inom IIoT-nätverk och strävar efter att minska cyberhotens inverkan. Arbetet har innefattat litteraturstudier av tidigare arbeten inom området och egna experiment där vi utifrån olika scenarier har utfört cyberattacker mot IIoT-nätverk som implementerar MQTT och OPC UA. Experimentens resultat visade att det utan adekvat säkerhet är möjligt att med relativt enkla medel komma åt och manipulera data. Resultaten belyser också skillnader mellan MQTT och OPC UA ur ett säkerhetsperspektiv. Litteraturstudien tillsammans med experimenten har resulterat i en sammanställning av de åtgärder som krävs för att efterleva konfidentialitet, riktighet och tillgänglighet i IIoT-nätverk som implementerar MQTT eller OPC UA. Det här arbetet bidrar till att öka förståelsen för cybersäkerhet inom IIoT-nätverk, och kan fungera som underlag vid val av protokoll för implementering hos MITC AB och deras samarbetspartners.

The current food system relies on global industrial agriculture and undermines food security partly by destroying the economic underpinnings of a localised food system. The potential efficiency of ecologically-integrated local agriculture addresses the economic and environmental implications of climate change associated with the food chain. The purpose of this study was to examine and compare existing North American models of commercially successful UA from northern climates and to create sample designs of an urban agricultural (UA) enterprise for sites in Guelph, Ontario. A case study approach and literature review was used to elicit key components of successful UA. Results indicate that profitable small scale, ecologically integrated agri-enterprises require a high degree of technical and business skills. Two site-specific designs provide examples of how a commercial urban farm can be incorporated into the city matrix of Guelph, Ontario. / Ontario Centres of Excellence (OCE)

Philosophiae Doctor - PhD / Breast cancer is one of the most common cancers among women in South Africa and the second leading cause of cancer death after lung cancer. According to the American Cancer Society 2015, women have a 12% chance of developing invasive breast cancer and a 3% chance of dying from it. Despite the wide variety of breast cancers e.g. lobular carcinoma in situ (LCIS) and ductal carcinoma in situ (DCIS), many share the same etiology and target tissue. Estrogen related carcinogenesis with regard to breast cancer typically results from the activation of distinct signalling pathways. These pathways are not mutually exclusive and are often constituted by receptor mediated stimulation of cell proliferation caused by specific transcriptional gene activation, reactive oxygen species (ROS) formation causing DNA damage and consequently mutations. The molecular pathways that cause drug resistance are not fully understood and the search continues to find novel targets for treatment. The effects of non-toxic triterpenes, oleanolic acid and ursolic acid and the role of autophagy and apoptosis as mechanisms to overcome drug resistance in breast cancer were studied in vitro in MCF-7 breast cancer cells and MCF10A breast cells. In this study the first aim was to establish the influence of OA and UA on cell growth and to see if opposing proliferation patterns could observed between the presumably ERɑ negative (ERɑ/ß -/+) MCF-10A and ERɑ positive (ERɑ/ß +/+) MCF-7 cells. This was followed by morphology studies to establish the possible presence of cytotoxicity and examination of molecular pathways contributing to the anti-cancerous properties of UA and OA and their validity as therapeutic agents. The MCF-7 breast cancer cell line and the immortalized normal mammary cell line, MCF-10A were treated with different concentrations of UA and OA for 6hrs, 12hrs, 24hrs, 48hrs, and 72hrs respectively. Cell morphology was studied in hematoxylin and eosin as well as Hoechst and acridine orange stained cells and viability was measured using crystal violet staining. Molecular techniques employed included the Tali® Apoptosis - and the cellROX assays, flow cytometry and western blotting. Morphological, viability and apoptotic studies have shown that at their lowest concentration, both UA and OA have anti-proliferative and apoptotic effects on MCF-7 and to a lesser extent on MCF-10A. Flow cytometric analysis of treated cells has demonstrated cell arrest in the S- and G2/M phase. The MCF-7 and MCF-10A cells growth inhibition effect may be due to increased autophagy and apoptosis as an alternative to decreased proliferation in MCF-7 cells. This possibility should be evaluated in further studies. The results showed that UA was more effective OA in decreasing cell numbers and it may be applied as treatment for breast cancer. Our observation has shown the treatment with OA and UA increased cell death in MCF-7 cells.The opposing proliferation patterns observed between the presumably ERɑ negative (ERɑ/ß -/+) MCF-10A and ERɑ positive (ERɑ/ß +/+) MCF-7 cells could possibly be ascribed to ERß forming homodimers that may facilitate proliferation, whereas ERɑ/ß heterodimers (expressed in 59% of breast cancers) are frequently associated with the ERɑ antagonising actions of ERß. The results indicate a trend towards biphasic and anti- proliferative effects of the reactants in breast cancer cells which may contribute towards the development of anti- cancer therapies. However, further work is must be done to identify the OA and UA mechanism(s) responsible for anticancer activity. / Libyan Embassy

Such complexity requires a large amount of data to be treated by the three levels of process control: field devices, control systems and management softwares. To use data effectively in each one of these levels is extremely important to industry. Many of today s industrial computer systems consist of distributed software systems written in a wide variety of programming languages and developed for specific platforms, so, even more companies apply a significant investment to maintain or even re-write their systems for different platforms. Furthermore, it is rare that a software system works in complete isolation. In industrial automation is common that, software had to interact with other systems on different machines and even written in different languages. Thus, interoperability is not just a long-term challenge, but also a current context requirement of industrial software production. This work aims to propose a middleware solution for communication over web service and presents an user case applying the solution developed to an integrated system for industrial data capture , allowing such data to be available simplified and platformindependent across the network / O controle de processos industriais t?m se tornado cada vez mais complexo devido ? diversidade de equipamentos de ch?o-de-f?brica, exig?ncia na qualidade e concorr?ncia de mercado.

Utilizar de forma efetiva os dados presentes em cada um desses n?veis ? de fundamental import?ncia para ind?stria. Muitos dos sistemas computacionais industriais de hoje s?o compostos de sistemas distribu?dos de software, escritos em uma grande variedade de linguagens de programa??o e desenvolvidos para plataformas espec?ficas. Desta forma, cada vez mais, pequenas e grandes empresas aplicam um investimento significativo para manter ou at? mesmo reescrever seus sistemas para diferentes plataformas.
