IDOKI SCF Technologies S.L. is a technology-based company, set up on September 2006 in Derio (Biscay) with the main scope of developing extraction and purification processes based on the use of supercritical fluid extraction technology (SFE) in food processing, extraction of natural products and the production of personal care products. IDOKI¿s researchers have been working on many different R&D projects so far, most of them using this technology. However, the optimization of a SFE method for the different matrices cannot be performed unless we have an analytical method for the characterisation of the extracts obtained in each experiment. The analytical methods are also essential for the quality control of the raw materials that are going to be used and also for the final product. This PhD thesis was born to tackle this problem and therefore, it is based on the development of different analytical methods for the characterisation of the extracts and products. The projects that we could include in this thesis were the following: the extraction propolis, the recovery of agroindustrial residues (soy and wine) and the dealcoholisation of wine.On the one hand, for the extraction of propolis, several UV-Vis spectroscopic methods were used in order to measure the antioxidant capacity and the total polyphenol and flavonoid content of the extracts. A SFC method was also developed in order to measure more specific phenolic compounds. On the other hand, for the recovery of agroindustrial residues UV-Vis spectroscopy was used to determine the total polyphenol content and two SFC methods were developed to analyse different phenolic compounds. Extraction methods such as MAE, FUSE and rotary agitation were also evaluated for the characterisation of the raw materials.Finally, for the dealcoholisation of wine, the development of a SBSE-TD-GC-MS and DHS-TD-GC-MS methods for the analysis of aromas and a NIR spectroscopic method for the determination of ethanol content with the help of chemometrics was necessary. Most of these methods are typically used in IDOKI¿s lab as routine analyses apart from others not included in this PhD thesis.

Ante el reciente aumento del dinamismo y la globalización en los mercados, los análisis, estrategias y planes de acción están adquiriendo una mayor importancia para todas las empresas. En una economía cambiante, anticiparse a los cambios y estar preparados para nuevas realidades es un objetivo prioritario de las empresas. El plan de marketing es un medio más para conseguir anticiparse a las nuevas características de los mercados. Cada empresa tiene características diferentes, por lo que es necesario que el plan se adapte a la organización y no al revés. Por ejemplo, en las grandes empresas se ha mostrado como un arma comercial determinante, pero en las PYMES puede convertirse incluso en un sustitutivo de la planificación estratégica. En éste trabajo se realizará un plan de marketing en la práctica para “Abereen Klinikak”, una PYME del sector veterinario, aplicando el método analítico sintético. Se realizará un análisis previo del mercado y un diagnóstico de la situación de la empresa, se marcarán los objetivos, estrategias y acciones a seguir, y se implantará un plan de control y seguimiento de ellos. Todo ello desde una forma estructurada y sistematizada, con el fin de seguir la mejor estrategia comercial posible para la empresa. Abstract Due to the recent increase of dynamism and market globalization, analyzes, strategies and action plans are becoming increasingly important for all businesses. In a changing economy, to anticipate changes and be prepared for new realities is a priority for companies. The marketing plan is another way of being able to anticipate the new market characteristics. Each company has different characteristics, so it is necessary that the marketing plan suits the organization and not vice versa. For example, in large companies it has been shown as a key commercial weapon, but for SMEs it could even become a substitute for strategic planning. In this project a marketing plan for "Abereen Klinikak", an enterprise which belongs to the SME sector, will be implemented. The marketing plan will be put into practice using the synthetic analytical method. To do so, preliminary market analysis and an assessment of the company’s situation will be done. Furthermore, goals, strategies and action steps will be scored, and a control and monitoring plan will be implemented. The plan will be put into practice in a structured and systematic way, in order to follow the best business strategy for the company.

One of the major concerns in an Intelligent Transportation System (ITS) scenario, such as that which may be found on a long-distance train service, is the provision of efficient communication services, satisfying users' expectations, and fulfilling even highly demanding application requirements, such as safety-oriented services. In an ITS scenario, it is common to have a significant amount of onboard devices that comprise a cluster of nodes (a mobile network) that demand connectivity to the outside networks. This demand has to be satisfied without service disruption. Consequently, the mobility of the mobile network has to be managed. Due to the nature of mobile networks, efficient and lightweight protocols are desired in the ITS context to ensure adequate service performance. However, the security is also a key factor in this scenario. Since the management of the mobility is essential for providing communications, the protocol for managing this mobility has to be protected. Furthermore, there are safety-oriented services in this scenario, so user application data should also be protected. Nevertheless, providing security is expensive in terms of efficiency. Based on this considerations, we have developed a solution for managing the network mobility for ITS scenarios: the NeMHIP protocol. This approach provides a secure management of network mobility in an efficient manner. In this article, we present this protocol and the strategy developed to maintain its security and efficiency in satisfactory levels. We also present the developed analytical models to analyze quantitatively the efficiency of the protocol. More specifically, we have developed models for assessing it in terms of signaling cost, which demonstrates that NeMHIP generates up to 73.47% less signaling compared to other relevant approaches. Therefore, the results obtained demonstrate that NeMHIP is the most efficient and secure solution for providing communications in mobile network scenarios such as in an ITS context.
