  • Application of comprehensive evaluation method based on combination weight in valve workshop layout

    The evaluation index system and evaluation method for the reliability of current workshop facility layout have not yet formed the standard. Taking the facility layout plan of valve production workshop as the research object, 9 evaluation indexes were put forward from four aspects of working environment, layout cost, production flexibility and management convenience, and a comprehensive evaluation system of valve production workshop layout was established. The AHP- entropy weight method was used to calculate the index weight. Based on the survey data and experts’ opinions, the evaluation model is used for analysis and evaluation. The evaluation results of the facility layout plan of valve production workshop are consistent with the reality. The results show that the weight method of this model not only considers the objective opinions of workshop personnel, but also uses the knowledge and experience of experts, which makes the workshop facility layout evaluation more objective and accurate, and provides reference for the standards of workshop facility layout evaluation.

  • APPLICATION OF ARTIFICIAL NEURAL NETWORKS FOR DETECTING MALICIOUS EMBEDDED CODES IN WORD PROCESSING DOCUMENTS

    Artificial Neural Networks have been widely used in security and privacy domains for alleviating the issues of malicious attacks. Several embedded codes like Visual Basic for Application Macros are reasonably powerful scripts that can help to automate iterative processes in word processing documents. It has been observed that, unethical hackers exploit these embedded scripts for their malicious intents. Since most of the Microsoft Word users are unaware of such malicious attacks because they are layman end users and mistakenly considers less suspicious contents. And therefore these hackers, prefer to use Microsoft Office documents as most vulnerable items for or Attack vectors. As a general approach, non-executable files are assumed to be less vulnerable than executable files. This implies that these document files could provide an easy and convenient exploitable pathway that can allow hackers to execute their intended malicious actions on the victim’s machine. This research paper presents an automatic detection of malicious embedded codes in general and Microsoft Office documents as a specific case for experimental analysis. This research paper considered only malicious behavior of the embedded codes i.e. checks the status of inclusion or exclusion of the executable code. The malicious datasets are developed to create a knowledge base where documents are pre-processed. Thereafter the data sets are disassembled using reverse engineering and then malicious features are extracted from the documents. In this research paper, nineteen different malicious keys were extracted. Later, feature reduction technique were applied. Based upon actions; these malicious keys were reduced to eight behaviors. Finally, a machine is trained using artificial neural network with eight input features; extracted from individual disassembled scripts. Afterwards, output nodes that represent malicious or benign behavior classify the existence of attack i.e. exists or does not exists. Based on the training model, a total of seven hundred ninety-two samples…

  • IMPACT OF MINERALFORMATION ON RESTORATION OF THE SOIL STRUCTURE IN NAKHCHIVAN AR AND GEOGRAPHICAL SPREADING LEGITIMACY

    The silt fractions have a great impact in soil structural formation. If the soil forming rocks don’t disturb, crush and weather, the soil forming processes on them occur weakly, the organic substances cause formation of the loamy stratums without completely turning. This mostly influences the initial soil forming layers. The reproduction minerals in these soils cause initial minerals majority by occurring weakly. If these processes occur quickly then they cause a gradual increase of the reproduction minerals and reduction of the initial minerals. The heights of the zones where the geographical spreading of such stratums is situated depend on levels.

  • SCIENTIFIC AND SPIRITUAL SIGNIFICANCE OF ADVANCED IRRIGATION TECHNOLOGY FOR INCREASING THE FERTILITY AND BIOLOGICAL ACTIVITY OF LOWLAND SLOPES OF THE SMALL CAUCASUS

    The article has been proven by the comparative analysis of long-term re-search results in the Karabakh region in the lowlands of the Lesser Caucasus, as well as comparative analysis of current research, as well as to the extent that these areas have been subjected to various forms of erosion. The productivity of self-cultivated agricultural crops has adversely affected the quality indicators and reduced productivity. At the same time, the complex physical and geographical conditions of the area, ever-increasing exogenous and anthropogenic pressures create favorable conditions for the development of all types of erosion processes in a wide range. The scientific and practical application of advanced microstruc-ture technology, as well as traditional backwatering, as well as traditional wetland irrigation, along with other complex measures in irrigated soil erosion soils, to improve fertility in erosional soils.

  • ON EVALUATING THE EFFECT OF SOIL TREATMENT AND FERTILIZER ON THE CULTIVATION OF GRAIN CROPS

    The article gives the results of studies of the effect of soil and fertilizer treatment on the productivity of winter wheat in the Ganja-Gazakh zone of Azerbaijan. The positive effect of fertilizers on plants of winter wheat is manifested only in well-cultivated soils with a reaction of the environment close to neutral. At the same time it is proved that between the intensity of the application of mineral fertilizers and the productivity of grain crops around the world, a close direct dependence is established. Consequently, the highest yield of grain here was obtained in the variant of dung 10t / ha + N90P90K60 57.1 c / ha, an increase of 24.3 c / ha or 74.1%, where the yield increase by 40-50% is due to the application of fertilizers

  • CREATION OF AUTOMATED LOW-INTENSITY IRRIGATION SYSTEMS CONTROLLED THROUGH AN INTERNET CHANNEL

    With the correct process management, low-intensity irrigation allows not only to drastically reduce water consumption for irrigation of agricultural crops, but also to provide the necessary microclimate for plants and the supply of water and fertilizers in the required amount directly to the root zone of plants, which contributes to the earlier entry of plants into the season fruiting and increased productivity while reducing water per unit of crop and reducing production costs. For this, we have developed a perfect safe technological system of automated irrigation based on IDAD with automated control of the controlled potential moisture supply of the plant, an optimized irrigation regime taking into account the controlled soil and agroclimatic parameters that affect the growth and development of the plant phase, while maintaining the ecological environment that contributes to obtaining a guaranteed and high-quality yield per unit area meeting the requirement of mi ovyh standards. The system of low-intensity irrigation created by the results of the study compared to traditional surface irrigation methods is more technologically demanding and in the remote areas from settlements it is difficult to provide qualified service; to ensure their possible efficiency, they require complex automation of the irrigation technological process.
