  • The planning and application of new developments in management of wastes. in hog farming is required to minimise the gaseous emissions from wastes and pollution of the aquatic environment. These strategies are enveloped in the "Farm Waste Management Plan" which identifies areas of the waste assets in form of plant nutrient and considers optimal manute collecting and storing procedures. The storage volumes for environmentally acceptable manure treatments and application methods are suggested. Good Waste Management Planning together with appropriate system design will ensure safe, reliable and effective waste handling.

  • Automatic mesh generation procedures applied to industrial now problems lead to complex mesh topologies where usually no special considerations to mesh resolution are taken. In the present study a fast and flexible solution algorithm in combination with generalized higher order discretization schemes is presented and its application to intake port calculation is demonstrated.

  • In this paper we apply the maximum principle to design of time optimal nonlinear sampled-data control systems. We introduce the general design procedures and the mathematical formalas for time optimal processes and trajectories. Then we show the application of the technique to determine the optimal control signal, control sequence, switching time and sampling period to the given 4th order process.

  • This paper focuses on the usage of the fuzzy set theory in decision making systems. The approach to calculation of generalized membership function, based on application of method of principal components is proposed. For solving of the problem of fuzzy forecasting the development of Bayes procedure is used. The structure of decision making system, in which following procedures are fulfilled, is discussed.

  • Properties of statistical process control procedures may not be derived analytically in many cases; however, the application of a Markov chain can solve such problems. This article shows how to derive the properties of the process control procedures using the generated Markov chains when the control statistic satisfies the Markov property. Markov chain approaches that appear in the literature (such as the statistical design and economic design of the control chart as well as the variable sampling rate design) are reviewed along with the introduction of research results for application to a new control procedure and reset chart. The joint application of a Markov chain approach and analytical solutions (when available) can guarantee the correct derivation of the properties. A Markov chain approach is recommended over simulation studies due to its precise derivation of properties and short calculation times.

  • Purpose: The purpose of this study is to apply the machine and deep learning methodology on error terms which are continuously auto-generated on the sensors with specific time period and prove the improvement effects of power generator prediction diagnosis system by comparing detection ability. Methods: The SVM(Support Vector Machine) and MLP(Multi Layer Perception) learning procedures were applied for predicting the target values and sequentially producing the error terms for confirming the detection improvement effects of suggested application. For checking the effectiveness of suggested procedures, several detection methodologies such as Cusum and EWMA were used for the comparison. Results: The statistical analysis result shows that without noticing the sequential trivial changes on current diagnosis system, suggested approach based on the error term diagnosis is sensing the changes in the very early stages. Conclusion: Using pattern of error terms as a diagnosis tool for the safety control process with SVM and MLP learning procedure, unusual symptoms could be detected earlier than current prediction system. By combining the suggested error term management methodology with current process seems to be meaningful for sustainable safety condition by early detecting the symptoms.

  • The sanitation inspection is the most frequently used procedure to protect foods prepared in foodservice establishments. In order to enhance foodservice inspections and to improve post-inspection remedial measures, more practical evaluation methods for sanitation are required. The HACCP approach is based upon factors which contribute to foodborne disease rather than of factors which relate to aesthetics. Contributing factors for foodborne diseases from food service establishments reported in USA, Candada, and England were analyzed to identify potential hazards during practical foodservice operations. Hazards were classified at critical control points by risk ranking, Twenty-two observable practical indicators relating to each contributing factor were selected and adjusted to standardized procedures and hazard determiners at critical control points, The weights for each inspection item were ranked as 1, 2, 3, 4, or 5 according to the risk level of contributing factors. And also application for the inspection item in different 6 types of work procedures were suggested for the use of specialized foodservice establishment and cafeteria, and of manager's self inspection in each establishment.
