The aim of this diploma thesis is to study the optical properties of new -conjugated molecules based on 1,4-di(4'-N, N-diphenylaminostyryl)benzene and their potential application in advanced imaging techniques of biological specimens, the so-called multiphoton microscopy. The thesis focuses mainly on the characterization of their optical properties and the determination of their two-photon absorption cross-section using a unique laser equipment. Furthermore, a suitable methodology for the preparation of nanoparticles from these molecules, their characterization and stability are also developed. The thesis also investigates the influence of structure on the optical properties of these molecules. The relation between the length of the conjugated system and the presence of substituents on the backbone has been shown for the optical properties of the molecules in the solvent, the position and shape of the two-photon absorption spectrum and the value of two-photon absorption cross-section. It has been shown that this substance retains its unique fluorescent properties even in the form of nanoparticles and therefore appears to be a suitable candidate for the observation of biological specimens using multiphoton fluorescence microscopy. The work contributes to the knowledge base for the design of the chemical structure of molecules with desired properties.

This diploma thesis is about measuring of family house, creating drawings and visualization of results. The family house is located in the Brno-Žabovřesky The house was surveyed by the classical geodetic method using a survey net built using GNSS (Global Navigation Satellite System). The results of field measurements were processed in the Groma program, graphic outputs (footprints of individual floors, sections and 3D model) in the MicroStation application. The documentation can be used mainly for the planned reconstruction of the family house and other related purposes.

The world population is projected to rise, and there is a growing concern of future food availability. Precision agriculture technologies are one solution to this problem as they aim to produce more food on less land. This study examines the adoption and intensity of precision agriculture technology usage by producers in North Dakota. Data from a North Dakota State University survey was collected and analyzed using an econometric double-hurdle model. Results of the study describe which producers adopt precision agriculture technologies, which technologies complement each other, and what affects the intensity of technology usage. Several technologies were found to have complementary effects on each other, larger farms are more likely to adopt PATs, and crop choices have varying impacts on the adoption and usage of PATs. Most of these findings agree with previous literature, although new light was shed on some new findings and predictions.

The goal of this diploma thesis is to design a modular air handling unit based on determined requirements. Modular air handling units provide great flexibility for consultants when work-ing on a project. Modular air handling units are assembled using many sections (heater section, cooler section, humidification section, fan section, etc) which gives the consultant an advantage to use only those sections necessary for particular project.

Nuestra investigación aborda el fenómeno de la eficiencia en el servicio de reparación de averías de vehículos ligeros en un concesionario automotriz dedicado a la venta y la postventa de este tipo de vehículos en Perú, de forma consistente con la aplicación de herramientas específicas de mejora; a saber, se usaron los presupuestos de la metodología Lean Manufacturing. El objetivo medular que cumple nuestro estudio es el planteamiento de procedimientos de mejora del cumplimiento de plazos de entrega en el servicio postventa de reparación de averías de vehículos a los clientes, mediante marco procedimental acorde con las exigencias del sector automotriz. La determinación del método se realizó en el marco de un diagnóstico situacional de la empresa automotriz en la que se efectuó el estudio con base en los lineamientos específicos del ciclo PDCA (Plan, Do, Check and Action), que se define como un modelo de resolución de problemas que utiliza insumos o herramientas de ingeniería como el Diagrama de Pareto, árbol de Problema y Objetivos, entre otras, de manera que la consecución de resultados se sustenta en la jerarquización cuantitativa de los problemas más apremiantes en el servicio, además de la medición de factores que posibilitan la determinación de causas-raíces de los diferentes problemas que se suscitan en la ejecución del servicio de reparación. En rigor, se trata de un trabajo con sustento empírico, dado que el análisis se realizó con información real derivada de la empresa, además de mediciones que se realizaron en el área de reparaciones, de las cuales se obtuvo como escollo principal la baja eficiencia en el servicio de reparación. La evaluación de la problemática derivó en la propuesta de un modelo acorde con las necesidades y exigencias del servicio de reparación, cuyo eje es el conjunto de herramientas Lean Manufacturing, el cual permitió generar procedimientos de mejora de los diferentes procesos. En cuanto a los instrumentos de solución asumidos, estos se sustentan en la determinación de las causas específicas que derivan del problema principal, esto es, la baja eficiencia en la ejecución de las reparaciones de la empresa. Así, en cuanto al procedimiento inadecuado usado en el servicio se planteó una herramienta de estandarización; en lo concerniente a la carencia de planificación de trabajos en el taller de servicios, se propuso un conjunto de herramientas como el Heijunka, Sistema Pull-Tack Time, Jidoka y Control Visual; entre otros. Estas fueron aplicadas como instrumentos de mejora de la eficiencia en el área de reparaciones. Producto de las evidentes mejoras, se presenta también una validación técnica y económica que orienta la toma de decisiones en cuanto a la ejecución de procedimientos idóneos para la consecución de un servicio eficaz; de esta manera, el costo de la implementación de las mejoras es de 101,843 soles y el valor actual neto (VAN) obtenido es de 129,488 soles, los cuales respaldan la rentabilidad como producto derivado de nuestra investigación. / Our research addresses the phenomenon of efficiency in the repair services of light vehicle breakdowns within an automotive dealership dedicated to the sale and after-sale services of this type of vehicles located in Peru, in a consistent way with the application of specific improvement techniques; namely, the Lean Manufacturing methodology budgets were used.

Compressive Sensing (CS) is a novel signal-processing paradigm that allows sampling of sparse or compressible signals at lower than Nyquist rate. The past decade has seen substantial research on imaging applications using compressive sensing. In this thesis, CS is combined with the commercial electromagnetic (EM) simulation software newFASANT to improve its efficiency in solving EM scattering problems such as Radar Cross Section (RCS) of complex targets at GHz frequencies. This thesis proposes a CS-RCS approach that allows efficient and accurate recovery of under-sampled RCSs measured from a random set of incident angles using an accelerated iterative soft thresh-holding reconstruction algorithm. The RCS results of a generic missile and a Canadian KingAir aircraft model simulated using Physical Optics (PO) as the EM solver at various frequencies and angular resolutions demonstrate good efficiency and accuracy of the proposed method.
