36	Der Einfluss von Fällmittelkombinationen auf die P-Retention in Sedimenten geschichteter Seen Wauer, Gerlinde 13 November 2006 (has links) Zur Restaurierung eutrophierter Seen kommen unterschiedliche chemische Fällmittel zum Einsatz. Eine neuartige Fällmittelkombination von Aluminat und Calciumhydroxid wurde in einem whole-lake-Experiment zur Restaurierung des Tiefwarensees (Mecklenburg-Vorpommern) eingesetzt. Dabei wurden im Laufe der 5 Jahre währenden Fällmittelzugabe ca. 2 t P zusätzlich im Sediment festgelegt. Dadurch wechselte der vorher hocheutrophe See in den mesotrophen Zustand. Mit Sedimentuntersuchungen und einer modellhaften Prognose wird nachgewiesen, dass die P-Retention erhöht und damit eine nachhaltige Wirkung der Restaurierung erzielt wurde. Weiterhin wurde ein neuentwickelter Nitrat-Depotstoff in Labortests und einem Enclosureversuch im Dagowsee (Brandenburg) angewandt. Der Depotstoff stellte das Nitrat zeitverzögert über mehrere Wochen nach der Applikation an der Sedimentoberfläche zur Verfügung. Die erhöhten Nitratkonzentrationen bewirkten zusammen mit dem gleichzeitig eingebrachten P-Bindungspartner Fe eine Vergrößerung der P-Bindungskapazität der behandelten Sedimente. Dadurch wurde die P-Rücklösung aus den Sedimenten mindestens ein Jahr lang beinahe vollständig unterdrückt. Beide Fällmittelkombinationen förderten zunächst hauptsächlich die Bildung anorganischer partikulärer P-Verbindungen im Sediment. Die bakteriellen Mineralisationsprozesse wurden nur indirekt bzw. zeitlich versetzt beeinflusst. Die sich andeutenden Veränderungen in Art und Intensität der mikrobiellen Stoffumsetzungen werden als Folge der Entwicklung der Sedimentation sowie des Sedimentmilieus diskutiert. Um das Gefahrenpotenzial beim Einsatz aluminiumhaltiger Fällmittel in der Seenrestaurierung einschätzen zu können, wurde unter Berücksichtigung der relevanten Mechanismen der Al-Toxizität und der Al-Chemie ein geeignetes Analyse-Verfahren für die Anwendung in karbonatreichen Seen angepasst und damit erstmals die gelösten monomeren Al-Hydroxide, die als potenziell toxisch wirkende Al-Spezies beschrieben werden, vor und während einer Maßnahme analytisch überwacht. Das Risiko einer Al-Giftwirkung auf Organismen im behandelten Tiefwarensee wird als sehr gering eingestuft. / In order to restore eutrophicated lakes different chemical phosphorus precipitation agents are utilized. A novel combined hypolimnetic aluminium and calcium precipitation treatment was first applied to restore Lake Tiefwaren (Mecklenburg Vorpommern, Germany) in a whole-lake-experiment lasting five years. About 2 t of phosphorus, also from deep (> 10 cm) sediment layers, were permanently bound during the restoration and the lake changed from a highly eutrophic to a mesotrophic state. Different investigations of the sediments and a model based prognosis demonstrate that the sediment’s P retention capacity increased indicating that a sustainable restoration effect was obtained. In addition a newly developed nitrate storing compound was tested in the laboratory as well as in a mesocosm experiment in Lake Dagow (Brandenburg, Germany). This compound provides nitrate at the sediment surface for some weeks. The nitrate together with the simultaneously added iron increased the P-retention of the treated sediments. Therefore the P release from sediments was suppressed for at least one year. The addition of both chemical compounds initially enhanced the P precipitation, whereas microbial processes of the P diagenesis were affected indirectly or temporally delayed. The observed changes in microbial activities are discussed as an effect of the changing sedimentation rate and chemical characteristics (pH, redox). In order to assess the risk of toxicity on aquatic organisms by the aluminium compounds used for lake restoration an analytical method was adapted for use in carbonate-rich natural waters. This enabled us for the first time to monitor dissolved aluminium hydroxide, a potentially toxic aluminium species, before and during a restoration process. The risk of a toxic effect on organisms in Lake Tiefwaren was found to be neglectible.

From the year 2020 and onwards, all new buildings should be erected as zero-emissionbuildings. The building’s design can reduce energy demands, but the current legal requirements do not favour energy-efficient designs. This study focuses on the design’s importance for the energy efficiency of buildings, i.e., energy-saving design. The impact of specific measures is difficult to calculate due to the complexity of reality. This study aims to highlight the measures that could reduce energy consumption in commercial buildings. Method: In order to provide answers to the issues stated in the report and to achieve the objective of the study, case studies are being conducted investigating three commercial buildings where deliberate decisions were made to use energy-reducing measures. Results and conclusions are based on qualitative interviews and literature studies. Findings: The energy-reducing design measures found to be of most importance used in the studied buildings are the form factor, the window portion and the thermal storage capacity. Moreover, significant savings are possible by carefully consider how solar energy can be limited or used in the building. Generally, buildings tends to become more technical, therefore technical knowledge early in the process is important to reach a good result. Economic incentives and clear objectives with right focus are also important for optimizing a building’s energy performance. The wording and the requirement levels in the Swedish building regulations highly controls the construction of energy efficient buildings. Implications: This study shows how energy efficient design is made today and provides an indication of what can be done and what should be prioritized. By imposing requirements on consumed energy instead of bought, energy efficient design could be favoured. Furthermore, this study suggests that a balance between windows, façade and solar shading are important energy-reducing measures. Regardless of selected energyreducing measures, a good performance is essential. Finally, this study shows that a methodical use of existing knowledge and technology makes a difference. Limitations: A lifecycle approach provides an overall picture of a building’s energy consumption. However, this study is based on the energy consumption during the operating phase. The result of this study does not take economic or aesthetic factors into account. This study is a comparative case study and is based on few but carefully matched cases. The selected cases are commercial buildings where deliberate decisions were made to use energy-reducing measures.

39	Design and implementation of personal health data monitoring and retrieval system for health providers Ojo-Seriki, D. F. 17 August 2020 (has links) M. Tech. (Department of Process Control and Computer System, Faculty of Engineering and Technology), Vaal University of Technology. / Personal health record system (PHRS) is a tool that is used in maintaining the health and wellness of an individual as well as helping with illness of an individual. PHRS gives the individual access to a wide range of credible health information, data, and knowledge. Individuals can use that access to improve their health and manage their diseases. Patients with chronic illness can track and manage their health in conjunction with their health provider, this will promote early intervention when they encounter an abnormality or complications. Continuous monitoring and storing of health information has been a challenge for patients and health providers. Personal health data monitoring and retrieval system for health providers was designed and implemented. The main aim of this study was to develop an accurate, secure and flexible personal health data monitoring and retrieval system for health providers (PHRS). This was achieved. The research showed that when a patient health information (Electrocardiogram (ECG) and temperature) was monitored, the heartbeat (ECG) sensor output the value as an analog value to the signal processing (NodeMCU) which was then converted to a digital value. The temperature sensor used in this research is a digital sensor which lowers the amount of ADC conversion that was done. The digital values are displayed on LCD, its send to a personal health data storage system which was designed for health information storage purposes. It also sends the value to a retrieval system which is an android application that is connected to the data storage system to display health information to the health providers from a remote location. Personal health data storage and the retrieval system are secure due to the Message queuing telemetry transport (MQTT) protocol used in the application layer. The MQTT protocol is secure due to the secure socket layer (SSL) which is an encryption based on presentation layer embedded inside the MQTT protocol. After the comparison of the software simulation and the prototype test, the differences in the value for the heartbeat and temperature sensor indicate 0.04 BPM and 0.04 oC which shows the accuracy of the sensing circuit. Personal health data monitoring and retrieval system developed is applicable and useful to multiple entities in and around South Africa such as; Ministry of health, hospitals, sport and recreations.

40	Introducing Generative Artificial Intelligence in Tech Organizations : Developing and Evaluating a Proof of Concept for Data Management powered by a Retrieval Augmented Generation Model in a Large Language Model for Small and Medium-sized Enterprises in Tech / Introducering av Generativ Artificiell Intelligens i Tech Organisationer : Utveckling och utvärdering av ett Proof of Concept för datahantering förstärkt av en Retrieval Augmented Generation Model tillsammans med en Large Language Model för små och medelstora företag inom Tech Lithman, Harald, Nilsson, Anders January 2024 (has links) In recent years, generative AI has made significant strides, likely leaving an irreversible mark on contemporary society. The launch of OpenAI's ChatGPT 3.5 in 2022 manifested the greatness of the innovative technology, highlighting its performance and accessibility. This has led to a demand for implementation solutions across various industries and companies eager to leverage these new opportunities generative AI brings. This thesis explores the common operational challenges faced by a small-scale Tech Enterprise and, with these challenges identified, examines the opportunities that contemporary generative AI solutions may offer. Furthermore, the thesis investigates what type of generative technology is suitable for adoption and how it can be implemented responsibly and sustainably. The authors approach this topic through 14 interviews involving several AI researchers and the employees and executives of a small-scale Tech Enterprise, which served as a case company, combined with a literature review. The information was processed using multiple inductive thematic analyses to establish a solid foundation for the investigation, which led to the development of a Proof of Concept. The findings and conclusions of the authors emphasize the high relevance of having a clear purpose for the implementation of generative technology. Moreover, the authors predict that a sustainable and responsible implementation can create the conditions necessary for the specified small-scale company to grow. When the authors investigated potential operational challenges at the case company it was made clear that the most significant issue arose from unstructured and partially absent documentation. The conclusion reached by the authors is that a data management system powered by a Retrieval model in a LLM presents a potential path forward for significant value creation, as this solution enables data retrieval functionality from unstructured project data and also mitigates a major inherent issue with the technology, namely, hallucinations. Furthermore, in terms of implementation circumstances, both empirical and theoretical findings suggest that responsible use of generative technology requires training; hence, the authors have developed an educational framework named "KLART". Moving forward, the authors describe that sustainable implementation necessitates transparent systems, as this increases understanding, which in turn affects trust and secure use. The findings also indicate that sustainability is strongly linked to the user-friendliness of the AI service, leading the authors to emphasize the importance of HCD while developing and maintaining AI services. Finally, the authors argue for the value of automation, as it allows for continuous data and system updates that potentially can reduce maintenance. In summary, this thesis aims to contribute to an understanding of how small-scale Tech Enterprises can implement generative AI technology sustainably to enhance their competitive edge through innovation and data-driven decision-making.
