<abstract xmlns="http://www.w3.org/1999/xhtml">Plant diseases are visually observable patterns of a particular plant. Varieties of plant diseases, which are recognized by human beings, are identical or look similar in appearance. In this paper, we have considered recognition of fungal disease symptom like powdery mildew, looking similar in appearance affected on different produce. The powdery mildew symptom affected on produce like grape, mango, chili, wheat, beans and sunflower are considered for classification. Colour and texture features are extracted from image samples of produce affected by powdery mildew symptom. The extracted features are then used as inputs to knowledge-based and artificial neural network (ANN) classifiers and tests are performed to classify image samples. The colour analysis is done using Red, Green, Blue (RGB) and Hue, Saturation, Intensity (HSI) models. Texture analysis is done using gray level co-occurrence matrix (GLCM). The overall average classification accuracy with colour, texture and combined features are 70.48 %, 70.07 % and 76.61 % respectively using the ANN classifier. The overall average classification accuracy has increased to 71.92 %, 80.60 % and 87.80 % with colour, texture and combined features respectively using the knowledge-based classifier.</abstract>

Recognition and classification of Produce affected by identically looking Powdery Mildew disease

<abstract xmlns="http://www.w3.org/1999/xhtml">The present article discusses the trends in the development of welding and weld overlaying on the threshold of the new millennium and during it. It presents the trends in the production of welding materials for welding and weld overlaying in industrially developed and developing countries. The structure of welding methods is also shown, giving priority to its development until 2020.</abstract>

Trends in Development of Weld Overlaying During The 21ST Century

<abstract xmlns="http://www.w3.org/1999/xhtml">This work is focused on determining the capability of production equipment in Volkswagen Slovakia, a.s. during the moulding of a car door. There were taken 150 samples from the moulding process that followed each other. Values were recorded on a Wenzel RAplus 1625 measuring machine. Subsequently, process stability was verified. It showed that measured values had a stable average value, and the process did not show irregularities in the diagrams of the <italic>X</italic> card and s card. After verification of stability, the values of <italic>Cm</italic> and <italic>Cmk</italic> were calculated, which exceeded the minimum requirement of 1.66 and 1.67, and the requirements for the capability of production equipment have thereby been met.</abstract>

Monitoring the Capability of Production Equipment in Organization

<abstract xmlns="http://www.w3.org/1999/xhtml">This work is focused on the design of a hydraulic device on which simulations of pressure shocks can be performed. The hydraulic device was constructed to allow simulations of pressure shocks transferred directly in operating conditions because simulation programs for hydraulic accumulators have only theoretical values while simulation on the designed hydraulic device enables obtaining specific readings directly in operating conditions that can be set. At the first control measurement on the hydraulic device, there occurred pressure shocks generated by the hydraulic device itself, these pressure shocks being undesirable in hydraulic circuits. In order to eliminate pressure shocks in the circuit, a diaphragm accumulator was added to the hydraulic device and was used to verify the function of simulating pressure shocks and eliminating undesirable pressure shocks. During the second control measurement on the hydraulic device, a reduction of unwanted pressure shocks was shown with the help of added diaphragm accumulator, thus the function of the hydraulic device to simulate pressure shocks was confirmed, which may also refect practical application in hydraulic circuits of mobile machines.</abstract>

Hydraulic Device for Simulation of Pressure Shocks

<abstract xmlns="http://www.w3.org/1999/xhtml">This paper is focused on evaluation of anticorrosion protection of inorganic metal coatings such as hot-dipped zinc and zinc-galvanized coatings. The thickness and weight of coatings were tested. Further, the evaluation of ductile characteristics in compliance with the norm ČSN EN ISO 20482 was processed. Based on the scratch tests, there was evaluated undercorrosion in the area of artificially made cut. Corrosion resistance was evaluated in compliance with the norm ČSN EN ISO 9227 (salt-spray test). Based on the results of the anticorrosion test, there can be stated corrosion resistance of each individual protective coating. Tests were processed under laboratory conditions and may vary from tests processed under conditions of normal atmosphere.</abstract>

Corrosion Resistance of Zinc Coatings With Aluminium Additive

<abstract xmlns="http://www.w3.org/1999/xhtml">Biomass provides a great diversity of input materials and universal use, not only for heat generation but also electricity generation in modern incinerators. For the most eficient use of solid biofuels, it is necessary to know their physico-chemical properties. The work focuses on the gravimetric analysis of selected types of biofuels. This paper presents the results of measurements for moisture content, ash and combustibles in selected solid biofuels. Experiments represent a follow-up to measurements performed to date.</abstract>
