Input parameters, ie factors defining the market price of agricultural‐purpose land, are interrelated very often by means of non‐linear ties. Strength of these ties is rather different and this limits usefulness of information in the research process of land market prices. Influence of input parameter changes to the input parameters in case when there are rather substantial changes may be determined in someone direction with a sufficient precision, whereas in other directions with comparatively small changes of input parameters this influence is difficult to be separated from the “noise” background. Taking into account the above‐listed circumstances, the concept of economical‐mathematical model of land market should be as follows: there is carried out re‐parameterisation of the process by means of introduction of new parameters in such a way that the new parameters are not interrelated, and the full process is evaluated at the minimal number of these parameters. These requirements are met by the main components of the input parameters. Then normalisation of the main components is carried out and dependencies on new parameters are determined. It is easier to interpret the dependencies obtained having reduced the number of input parameters and the higher the non‐linearity of interrelations of primary land market data, the greater effect of normalisation of input-parameter components. The results are compared with the valuations of experts.

Vibratory Feeding

A brief review of previous work on the mechanics of vibratory conveying is presented followed by a new theoretical analysis of vibratory feeding on a track which vibrates with simple harmonic motion and where a phase difference may exist between the parallel and normal components of the track motion. For a wide range of practical conditions, the theoretical predictions are found to agree closely with the results of experimental tests. These show that certain fundamental limitations exist in the performance of conventional feeder drives where the two components of track motion are in-phase. From further theoretical and experimental work, it is shown that under conditions where the appropriate phase difference exists between the two components of track motion, many practical advantages over conventional vibratory feeding are obtained. With a new design of vibratory bowl feeder drive based on the results of the work, significantly higher conveying velocities may be obtained under stable feeding conditions and, further, these high conveying velocities are virtually independent of the coefficient of friction between the component and the track. The results of the present work apply equally to the design of spiral elevators and in-line vibratory feeders.

A statistical analysis of the performance of a vee cutout orienting device used in a vibratory bowl feeder is presented. The results of experimental tests are described and compared with the analysis. From the information thus obtained it is possible to design and build such a device without the need for trial and error procedures and to obtain 100 percent efficiency.

This paper presents the results of defining the mathematical model which describes the dependence of leaching degree of Al2O3 in bauxite from the most influential input parameters in industrial conditions of conducting the leaching process in the Bayer technology of alumina production. Mathematical model is defined using the stepwise MLRA method, with R2 = 0.764 and significant statistical reliability - VIF<2 and p<0.05, on the one-year statistical sample. Validation of the acquired model was performed using the data from the following year, collected from the process conducted under industrial conditions, rendering the same statistical reliability, with R2 = 0.759.

Abstract The design and implementation of vibratory bowl feeders involves the analysis of the behavior of the parts as they are conveyed up the bowl track. This paper presents the results obtained in a series of experiments which study the effect of the vibration amplitude in the feeder on the dynamic orientations of a family of parts. The objective of the study is to investigate how complex parts behave in a vibratory bowl feeder and try to establish a relationship between the orientation of the parts and the vibration amplitude of the bowl feeder. The study consisted of experimenting with four types of connectors that were similar in shape but differ in proportions. By experimenting with a part family, we intend to establish and generalize in the near future a relationship between the tendency of the parts to fall in certain orientations, the amplitude of vibration in the feeder, and geometric features or mass properties. The acquired knowledge could then be incorporated in computer aided design programs, together with existing theory on feeder design, to specify orientation devices and operating parameters in the vibratory bowl feeder.
