Zlepšení posklizňového zrání meruněk účinkem exogenního etylenu
Růžička, David
Was researched influence of exogenous ethylene on apricots of variety "Velkopavlovická". The fruits were harvested at the maturity stage of the primary content of chlorophyll in their skin. At the plant material was determined by the concentration of titratable acids, fruit penetrometer firmness and soluble solids content. Additionally, a loss of weight. The fruits were treated with exogenous ethylene for 24 hours in a sealed vessel at 200 ppm concentration. Concentration verified by gas chromatography (GC / MS). Were stored for 14 - days at 3 ° C and 20 ° C. For each group of fruit was also a control group (untreated exogenous ethylene). Laboratory tests performed on days 0, 7 and 14 days after treatment. For fruit treated with ethylene decrease the strength of fruits and color changes - loss of chlorophyll. On the other properties of fruits have more influence than ethylene storage temperature. Sensory evaluation was carried out of all categories of fruits according to the parameters taste, firmness, color. Top evaluated fruits were treated exogenous ethylene stored at a temperature of 20 ° C and worst fruits were evaluated control (untreated) stored in the temperature of 3 ° C.

Design of optoelectronic sensor for biological tissues
Balík, Zdeněk ; Bartlová, Milada (referee) ; Tománek, Pavel (advisor)
Biological tissues are optically inhomogeneous and absorbent materials. They are comprised of various structures such as cells, cell organelles, and various fiber structures. Due to these structures leads to different interactions with the light and phenomena such as absorption, scattering and polarization of light. Different ultrasonic, electromagnetic, electrical and optical methods are used for meat ageing detection. Muscles are turbid anisotropic media, they exhibit changes in electrical and optical properties according to the direction of the electrical and optical fields in the sample. The diploma work assesses the feasibility of impedance measurements for meat ageing detection and their comparison with optical measurement of scattered polarized light. Two different sample were used: pork chop slices and chicken breasts were used for their relative homogeneity. The electrical method is a promising method due to the possibility of getting much information and realizing cheap and fast enough measurement systems. The proposed optical method allows measure the rotation of polarization plane with meat ageing in the range of 95 degrees within considered period. Through the first promising results obtained in this thesis, a further work has to be provided to determine closer relationship between optical scattering characteristics, electrical anisotropy in ageing-related tissue structural properties.

Způsoby a metody zpomalování zralosti jablek
Majorová, Anežka
Three cultivars of apple (Idared, Prima, Golida) were harvested in three stages of ri-peness (unripe, ripe, overripe) that were stored for 30 days in two different temperatures (2 °C a 20 °C). On all cultivars, the ripeness was studied during the storing based on objective measurements. The performed measurements enabled to determine 3 basic criteria (penetration stress, soluble solids, acid-based titration). From the stored cultivars, Prima was ripe in the time of measurement, cultivars Idared and Golida reached similar in descibed parameters that are stated by the average and standard deviation. The aim of this work was to find optimal ripeness of apples, especially for long-term storage. Knowing of materiál composition during the harvest was important for studying of ripeness. The changes and values are observed and recorded. According to these values, the conditions for every cultivar for long-term storage and maintenance of apples at optimum ripeness are determined.

Test process improvement and software quality assurance models
Došek, Tomáš ; Borovcová, Anna (advisor) ; Buchalcevová, Alena (referee)
Testing often takes between 35 and 50 percent of the total costs of software development projects. Still, the role of testing tends to be underestimated. High costs that are being spent on software testing make a reason for looking for systematical approaches for making the testing processes efficient. Test process improvement models offer such approaches. These models are subject of this thesis. Implementation of process improvement models can be an expensive, long-term activity. Therefore, reasons need to be found, why is important to use such models. Reasons and motivations for using improvement models are demonstrated in the first part of this thesis. It turned out that software testing has, by its historical development, come to the state, when it contains so much theory that companies have a problem absorbing all the knowledge to make testing processes efficient. Therefore, improvement models offer a solution to this problem. This thesis is primarily focused on Test Maturity Model Integration (TMMi), which is being analyzed thoroughly. The work searches for possibilities and limitation of using the model and it summarizes current experiences with the model. Because the TMMi model does not contain a practical assessment method, such method is proposed in this thesis. The assessment method will help organizations using the model. Beside TMMi, the thesis provides an introduction into three other models: Test Process Improvement (TPI), Capability Maturity Model Integration (CMMI) and Critical Testing Processes (CTP). All four models are subject to a comparison based on specified criteria. Results of the comparison are analyzed to identify for which situations individual models suit best. The comparison will help organizations to choose the right model for their needs.

Raising test process maturity in IT company
Kučera, Martin ; Buchalcevová, Alena (advisor)
This thesis deals with the issue of process optimalization in the field of test discipline which is a fundamental part of software development. An approach providing improvement of test processes is applied in the environment of a test department in a selected company. Concept of raising process capability and maturity presented in CMMI model is used for this purpose. The first goal of the thesis is a provision of theoretical background devoted to software testing, process approach and capability and maturity models, that will accommodate enough with the clarity of the document text, as well as to provide insight into the whole subject. Theoretical interpretation will be compiled using on-line resources available for free, author's bachelor thesis and facts obtained through the studies and from educational materials. Attention will be focused on the definition of important facts and mutual relationship between the areas of interest. Description of initial state, changes carried out and current state of organizational structure, processes and documentation in the test department of the company was selected as a following goal. Process models consisting of diagrams, description tables and textual characteristics of identified processes will be created. Structure of documentation and of its parts will be accentuated through the description of documentation state and changes, furthermore a chronological sequence of taking the documents into practice and explanation of its importance in testing will be present. In order to offer a comprehensive view, a description of organizational structure and department member's competence will be available. As the last goal, arrangement proposal to obtain a higher process maturity and further improvement of documentation and organizational structure was chosen. Process areas and recommendation related to the processes of test discipline will be selected from the CMMI model. The selected content will be interpreted as to form a partial steps for direct use in test department. Appropriate sequence of the steps will also be set to serve well the purposes of the department. Beyond the scope of arrangement proposal, separate recommendations in areas of organizational structure, processes and documentation will be present. The thesis summarizes key facts about and arrangements made in organizational structure, processes and documentation of the test department in the selected company in the period of last two years. The contribution lies further in the creation of so far absent process models of the test department which capture the form of test processes in two points in time, and especially in the complete arrangement proposal aiming to raise process maturity and optimize organizational structure and documentation.
