One of the requirements for a successful insemination in horse breeding is the selection of quality stallions which produced ejaculate in enough quantities and of good quality. For this purpose were discovered methods of dealing with the evaluation of semen quality. In this dissertation was ejaculate evaluated by using an objective computerized method CASA, system SCA. Monitoring the quality of sperm was performed on 11 breeding stallions involved in artificial insemination fresh sperm in ZH Písek. 53 samples of ejaculate were evaluated. Volume, sperm concentration, total and progressive motility and sperm vitality were monitored. Volume of ejaculate was from 20 to 127.5 ml. Average values of sperm concentration for individual stallions were from 104.18 to 384.4 M/ml. Average values of total motility were moving by interval from 51.23 to 89.54 %. Average progressive motility was move from 12.99 to 47.12 %. At sperm vitality were discovered average results from 35.16 to 71.21 %. The average value of individual stallions was identical to the Decree of the Ministry of Agriculture, which sets minimum requirements for quality indicators for short-term preservation of semen. Also the quality of the semen of stallions was compared by age. The first group was made by stallions to 10 years old and the second group were older stallions. It was found that the younger stallions to 10 years had higher semen volume and greater sperm concentration. Stallions older over 10 years had higher levels of total and progressive motility and sperm vitality. Next ejaculate quality was evaluate by the time interval between samples. Regular taken from stallions is doing better ejaculate quality but the time interval between samples is important. The best values were found in samples with interval between the sampling 4 or more days. The worst quality of sperm was in the samples with the interval between 1-2 days.

The purpose with this project was to create a virtual reality game were the users should be able to carry out a thinning. The main goals are to use real forests terrains as terrain models in the game, the GameObjects and the teleportation system in the application should be able to handle changing terrains and the application should not cause virtual reality sickness. The application has been developed with the help of the game engine Unity and plugins from Unitys own asset store. User tests and measurements will be carried out in order to evaluate if the game causes virtual reality sickness or not. The results shows that it is possible to use real forests terrains and that the solution is suited for this application. The downside is that in order to use real life terrains several steps has to be taken and that the terrain object has to be designed manually. It also shows that the GameObjects and the Teleportation system has been implemented in a way so they can handle changing terrains. Furthermore it shows that some of the functionalities of the application could be improved, especially the scoring system. The users tests and the measurements showed that the application isn't causing virtual reality sickness but it also showed that the users feels like there are things missing in the application

Another factor to be considered in manufacturing organizations is the decrease in profit margin due to higher competition in global market and technological innovations. The profit to be made rests almost exclusively to the management of the flow of the production process by streamlining operations and reducing the lead-time of production. In this context, it has demonstrated the inappropriateness of deterministic and reductionist management models, assessing the behavior of the system as the sum of the conduct of the parties, through linear relationships between the guidelines established by management and the expected results of the production operation. This is equivalent to a view that, in taking up a production plan that can be accomplished by the availability of raw materials and production resources, machinery and manpower become simply a matter of implementation and monitoring of the plan of production. What has been found is that the systemic behavior of such organizations is described by interactions between its internal and external parties, where many of these interactions have ordered and non-ordered features simultaneously. Moreover, they are very dependent on the initial conditions for the realization of your planning. It is also observed that these behavioral characteristics of the manufacturing organization can be described as typical of Complex Adaptive Systems (CAS). For these organizations the representative system of the production process is a subsystem of the business organization and can be described as an SCA. In the manufacturing system, parties are formed by agents that have interactions with each other and with the productive environment differently, ie, the interaction of the agents of production differs from the agents of quality in relation to the production environment. The actions of these interactions are complex and ordered and non-ordered while allowing to establish a linear relationship between causes and effects. In this context of complexity, the production system proves more creative and able to adapt in the face of internal and external environment changes. Knowledge management applied systemically through information technology, called MES (Manufacturing Execution Systems), can increase the learning capacity of the system resulting in increased productivity and profitability of the production process evaluated by performance indicators. It will be demonstrated in this dissertation, the fact that knowledge management can establish a better definition of efficient and effective operational actions, from the extraction of tacit knowledge, obtained through interactions with the productive environment, transformed into explicit knowledge and disseminated among other agents. The MES will assist in broadening the perception of the production environment and structured description of the procedures related to the explicit knowledge and also to disseminate knowledge to mitigate losses. The consistency of actions will establish the identity of the organization and consequently its ability to adapt and self-organization. / A globalização da economia tem apresentado comportamentos mercadológicos dinâmicos e indeterminísticos e tem exigido das organizações empresariais, particularmente as de manufatura de commodities, uma maior capacidade de adaptação a essas mudanças cada vez mais frequentes. Outro fator a ser considerado nas organizações de manufatura é o decréscimo da margem de rentabilidade em função da maior competição no mercado globalizado e das inovações tecnológicas. O lucro a ser obtido cabe quase que exclusivamente à gestão do fluxo do processo produtivo através do enxugamento das operações e a redução do tempo de atravessamento de produção. Neste contexto, se tem demonstrada a inadequação de modelos de gestão determinísticos e reducionistas, que avaliam o comportamento do sistema como a somatória dos comportamentos das partes, através de relações lineares entre as diretrizes estabelecidas pela gestão e os resultados esperados da operação da produção. Isto equivale a ter uma visão de que, em se tendo um plano de produção que possa ser atendido pela disponibilidade de matéria prima e recursos produtivos, máquinas e mão de obra passam a ser, simplesmente, uma questão de execução e acompanhamento do referido plano de produção. O que se tem constatado é que os comportamentos sistêmicos de tais organizações se descrevem pelas interações entre suas partes internas e externas, onde muitas dessas interações apresentam características ordenadoras e desordenadoras simultaneamente. Além disso, elas são muito dependentes das condições iniciais para a realização de seu planejamento. Observa-se também que essas características comportamentais da organização de manufatura podem ser descritas como típicas dos Sistemas Complexos Adaptativos (SCA). Para estas organizações o sistema representativo do processo produtivo é um subsistema da organização empresarial e pode ser descrito como um SCA. No sistema de manufatura, as partes são formadas por agentes que apresentam interações entre si e com o ambiente produtivo de forma diferenciada, isto é, a interação dos agentes de produção difere da dos agentes de qualidade em relação ao ambiente produtivo. As ações dessas interações são complexas e ordenadoras e desordenadoras simultaneamente não permitindo estabelecer uma relação de linearidade entre causas e efeitos. Nesse contexto de complexidade, o sistema produtivo se mostra mais criativo e capaz de se adaptar diante das mudanças internas e externas do ambiente. A gestão do conhecimento aplicada de forma sistêmica através da tecnologia de informação, denominada de MES (Manufacturing Execution Systems), pode aumentar a capacidade de aprendizado do sistema resultando no ganho de produtividade e rentabilidade do processo produtivo avaliadas por indicadores de desempenho. Será demonstrado nessa dissertação, o fato de que a gestão do conhecimento pode estabelecer uma melhor definição das ações operacionais eficazes e efetivas, a partir das extrações dos conhecimentos tácitos, obtidos através das interações com o ambiente produtivo, transformados em conhecimentos explícitos e disseminados entre os demais agentes. O MES auxiliará na ampliação da percepção do ambiente produtivo e na descrição estruturada dos procedimentos correspondentes aos conhecimentos explícitos e também para disseminar conhecimentos para atenuação das perdas. A coerência das ações estabelecerá a identidade da organização e, consequentemente sua capacidade de adaptação e auto-organização.

The interest for Business Process Management (BPM) is increasing in Sweden. Government agencies such as the Swedish Nation Board of Student Aid (CSN), the Swedish Companies Registration Office (Bolagsverket) and the Swedish Social Insurance Agency (Försäkringskassan) are implementing BPM into their organizations. Sogeti is an IT-consulting company that has employees that works at CSN with BPM, and one of the tools they use for integration is IBM Integration Designer. Since this technology is new and is gaining popularity, there is a need for increased knowledge about it. This thesis report explores the tool IBM Integration Designer, regarding its different ways to integrate with systems and compares the different options for exposing the integration solu- tions. By researching documentation from IBM, and by learning how to use the tool itself, knowledge could be acquired about IBM Integration Designer. The result was an implementation of the five different export bindings: SCA, HTTP, SOAP over HTTP, Enterprise JavaBeans (EJB) and Java Messaging Service (JMS), a comparison of these export bindings and finally a service in IBM Inte- gration Designer that accesses a database and uses an external SMS API to send text messages. The result has been satisfactory to the purpose of this project in giving insight into IBM Integration Designer, one of the popular tools for inte- grating BMP.

SCA transports timber via rail from railway terminals in western Sweden to saw and/or pulp mills located on the east coast. Sometimes timber wagons are lost due to damages inflicted when loading the wagon. Wagons can also be decommissioned for maintenance conducted by the Swedish Transport Administration. Both situations are unpredictable and causes many types of problems. If the wagons could be automatically traced these problems could be predicted and pre-emptive actions could be taken. All wagons used by SCA are equipped with RFID tags and RFID readers are installed at the railway terminals. The purpose of this thesis is to equip the RFID readers with Internet access, collect the data read by the RFID readers and present this data in a single page web application. The actual data collection is done by an already existing system which pushes the train data to the back-end part of the application. The front-end part is made with a JavaScript framework named Ember.js and the back-end part is made with ASP .NET Web API and SQL Server. The application is finished and verified with various tests but is not put in production due to a negotiation delay between SCA with a third-party consultant.

Teaching conversational strategies has been effective for a wide array of clients with acquired neurologic disorders and their caregivers. Research indicates positive results for Supported Conversation in adults with Aphasia (SCA) secondary to stroke. Applying this method to work with caregivers of persons with memory impairment could prove to be a valid intervention tool. This investigation will examine the applicability of SCA with persons with memory impairment and their familial caregivers. This pilot study is intended to create a conversation regarding SCA and its implementation with persons with memory impairment who still live in the community with their caregivers. Analysis between the pre-training and post-training scores showed a trend to wards significance for Time (F(1, 9) = 0.064), no significance for Measure (F(3, 9) = 0.558), and no significance for the interaction of Time*Measure (F(3, 9) = 0.276). The effect size for Time was 0.732, for Measure was 0.494 and for Time*Measure was 0.956.

Yes / Purpose: The COVID-19 outbreak has imposed extensive shocks embracing all stages of the food supply chain (FSC). Although the magnitude is still unfolding, the FSC responds with remarkable speed, to mitigate the disruptive consequences and sustain operations. This motivates us to investigate how operationalising supply chain agility (SCA) practices has occurred amid the COVID-19 crisis and expectations for how those practices could transform the supply chain in the post-COVID-19 era. Design: Following an exploratory case-based design, we examine the various agile responses that three supply chains (meat, fresh vegetables and bread) adopted and elaborate using the dynamic capability (DC) theoretical lens. Findings: First, the findings demonstrate how, in the wake of the COVID-19 pandemic, each affected case pursued various agile responses through sensing and seizing capabilities. Sensing includes identifying and assessing the relevant opportunities and threats associated with the specific supply chain context. Seizing involves acquiring, combining and modifying the tangible and intangible resources at the firm and supply chain levels. Second, supply chain transformation is likely if firms and their supply chain develop the sustaining capability to ensure that the desirable changes outlast the crisis. Originality: This study provides a novel and unique perspective on the role of SCA in crisis—in this case, the pandemic. We synthesise the empirical stories of the agile responses in the FSC and elaborate on the DC framework, to identify theoretical and practical implications. We establish the sustaining capability as the missing DC capability for enabling transformation in the post-COVID-19 era. Practical contribution: This study provides an actionable guide for practitioners to develop agile responses to systemic changes in times of crisis and to sustain favourable changes so as to enable their outlasting the crisis. / Project 777742: EC H2020-MSCA-RISE-2017

A current field of research today is machine learning because it can simplify everyday life for human beings. A functioning system that has learned specific tasks can make it easier for companies in both cost and time. A company who want to use machine learning is SCA, who owns and manages forests to produce products. They have a need to automate forest classification. In order to evaluate forests, and to plan forestry measures, the proportion of leafy tree that is not used in production must be determined. Today, manual work is required of people who have to investigate aerial photos to classify the tree types. This study investigates whether it is possible, through machine learning, to teach a computer to determine whether it is leaf or not in photographs. A program is constructed with the library ImageAI which receives methods for training and predicting information in images. It examines how the choice of neural network and the number of images affects the safety of the models and how reliable the models can be. Exercise time and hardware are also two factors that are investigated. The result shows that the neural network ResNet delivers the safest results and the more images the computer exercises, the safer the result. The final model is a ResNet model that has trained on 20,000 images and has 79,0 percent security. Based on 50 samples, the mean value for safety is 90,5 percent and the median is 99,6 percent. / Maskininlärning är idag ett aktuellt forskningsområde som kan förenkla vardagen för oss människor. Ett fungerande system som har lärt sig specifika uppgifter kan underlätta för företag i både kostnad och tid. Ett företag som vill använda maskininlärning är SCA, som äger och förvaltar skog för att producera produkter. De har behov av att automatisera klassificering av skog. För att värdera skogar, samt planera skogsåtgärder, måste andelen lövträd som inte används i produktionen bestämmas. Idag krävs det manuellt arbete av personer som måste undersöka flygfoton för att klassificera trädtyperna. Denna studie undersöker om det är möjligt, via maskininlärning, att lära en dator avgöra om det är löv eller inte i ortofoton. Ett program konstrueras med biblioteket ImageAI som erhåller metoder för att träna och förutsäga information i bilder. Det undersöks hur valet av neuralt nätverk och antalet bilder påverkar säkerheten för modellerna samt hur tillförlitlig modellerna kan bli. Träningstid och hårdvara är också två faktorer som studeras. Resultatet visar att neurala nätverket ResNet levererar säkrast resultat och desto fler bilder datorn tränar på, desto säkrare blir resultatet. Den slutgiltiga modellen är en ResNet-modell som tränat på 20 000 bilder och har 79,0 procents säkerhet. Utifrån 50 stickprov är medelvärdet för säkerheten 90,5 procent och medianen 99,6 procent.

Recent advances in understanding lung biology have shown evidence for the existence of resident lung stem cells. Independent studies in identifying and characterizing these somatic lung stem cells have shown the potential role of these cells in lung repair and regeneration. Understanding the functional characteristics of these tissue resident stem/progenitor cells has gained much importance with increasing evidence of cancer stem cells, cells in a tumor tissue with stem cell characteristics. Lung cancer is most commonly characterized by loss of p53 function which results in uncontrolled cell divisions. Incidence of p53 point mutations is highest in lung cancer, with a high percentage of missense mutations as a result of tobacco smoking. Certain point mutations in p53 gene results in its oncogenic gain of functions (GOF), with enhanced tumorigenic characteristics beyond the loss of p53 function. However, there are no available data on characterization of lung stem cells carrying GOF mutations and correlating them with those of normal stem cells, in this study, for the first time we show that percentage of Sca-1 expressing subpopulation is significantly higher in the lungs of mice carrying p53 GOF mutations than those in lungs isolated from p53+/+ wild type mice. Further, we successfully established lung cells differentially expressing two cell surface markers, Sca-1 and PDGFR-α, with results demonstrating existence of different subpopulations of cells in the lung. Results from our project demonstrate the importance of p53 GOF mutations as correlated with specific lung cell subpopulations.
