Innovation of experimental e-nose for odor analysis in the food industry
Janošíková, Pavla ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This work deals with innovation of the program for processing data acquired from sensory device known as electronic nose. The work introduces possibilities and utilization of a electronic nose. Furthermore it introduces some of the best known analysis for odor recognition that are used mainly in the food industry focusing on principal component analysis. The work focus on creation of mobile application that process data from a simple electronic nose and on improvement of ammonia and CO2 measurement accuracy. The program must also allow wireless data reception, their processing and storage.

Odor analysis program for experimental electronic nose
Janošíková, Pavla ; Szendiuch, Ivan (referee) ; Adámek, Martin (advisor)
This work deals with processing data acquired from sensory device known as electronic nose. The work introduces readers to a few possible designes of electronic noses and to some of the best known analysis for odor recognition that are used in food industry. The work focus on a principal component analysis and a creation of program that process data from a simple electronic nose. The program not only receives data, but it even saves them and process them for better clarity of results. Using this program it is possible to create a new database and identify an unknown sample if its data are already stored in database. The part of this work is an experiment to see if the created program is able to recognize some odors better then a human nose.

Biometrical Liveness Detection - Mechanical Characteristics
Zaklová, Kateřina ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
Main focus of this thesis is the detection of liveliness of the finger by the means of mechanical methods. Theoretical part of the thesis describes biometric systems, their reliability metrics, various kinds of sensors and methods of liveness detection. Two methods are covered in detail - liveness detection by odor and liveness detection by temperature. The thesis also illustrates implementation of the application for liveness detection by temperature and evaluates range of experiments carried out during the research.

Software for the processing of multidimensional data from gas sensors
Almazov, Denys ; Skácel, Josef (referee) ; Adámek, Martin (advisor)
This work deals with realization and testing software for processing multidimensional data from a gas sensor. This work introduces readers to some multidimensional data processing method. The part of work is a description and usage PCA method, description of the smell or taste detection device – electronic nose, realisation and testing of the program for preprocessing and processing data. Preprocessing data program can visualise data from device on the graf in real time and save it to the file. Data processing program can read data from file, decrease their dimensionality and visualize results in 2D graf. This program was tested on a simple electronic nose that contains three sensors.

Identification of volatile compounds from waste products of aromatic plants with electronic nose
Malina, Miloň ; Klouček, Pavel (advisor) ; Martin, Martin (referee)
The goal of this work was to develop a simple and inexpensive method for evaluating the content of valuable volatile substances in the waste products of aromatic plants based on using of electronic nose prototype constructed in the Czech University of Life Sciences. A literature review engaged the current issue of the use of essential oils, possibilities for production and summarizes information about the currently utilized electronic noses. The methodology described functions and structures of used prototype of electronic nose. Testing of the prototype of the electronic nose have been done by measurement of the substances standards contained in essential oils (anisole, carvacrol, B-pinene, B-citronellol, carvone) and model waste materials (oregano, lemon balm, anise, caraway, mountain pine needles). The measured values were used to make quantitative and qualitative analyzes which were used to assess the functioning of the electronic nose. The hypothesis of this work was to claim that the electronic nose, which was developed at the Czech University of Life Sciences, can be used for evaluation and recognition of valuable volatile substances contained in waste products of aromatic plants. Quantitative analysis showed that some of the sensors are able to respond well to a change in concentration of the measured substance. Qualitative analysis showed that the electronic nose is capable of distinguishing between different materials and can identify previously measured material among others. Electronic nose despite the lower quality of the components used and the overall low cost of its construction have demonstrated great potential for assessing the content and identification of volatile compounds. Conclusion is that there are several changes and improvements, especially in the software for measured data processing, that have to be made in the future.
