Major influences on business purchases

Various participants are involved in the purchase of the goods and services for the business. A common practice when purchasing important goods is the creation of purchasing committees composed of technical experts and senior executives. In addition, B-to-B marketing professionals are now facing a new generation of supply managers who are more qualified. Therefore, companies need to have well-trained marketing professionals able to work with these well-prepared buyers. The purpose of the article is to present a model of business buyer behavior and to find out how marketing and other incentives affect the purchasing organization and cause certain reactions from the buyer

CONSEQUENCES OF THE BASIC LAW OF FLAT INTERLOCKING OF INVOLUTE CYLINDRICAL GEARS

Three consequences based on the basic law of the flat interlocking have been determined that allow the generation of asymmetric tooth profile on different poloidal circles. Gears with asymmetric profile are used in both mechanical engineering and measuring devices. Qualitative indicators of engagement that cannot be accomplished with a symmetric profile have been developed. A specific example of generation III has been presented. The qualitative indicators of engagement, which are invariant to the parameters of the tool, have been improved

MICROPROCESSOR SYSTEM FOR TEMPERATURE INVESTIGATION OF AC MACHINES

The paper is about four channel microprocessor system for temperature measurement during static and running mode. It incorporates microcontroller type PIC18F452 and employs sensors which convert temperature into voltage. In addition it features optional connection to a PC for storing and processing amassed data. Based on this system a new method is proposed for analysing overheating and cooling of individual parts of asynchronous electric machines. A set of differential equations is derived which later on are processed by MATHCAD software. Obtained results can be presented in tabular or graphic form. The outcome of resolving this task is in the relative ease with which it is possible to establish overheat of various machine parts. Similarly, such approach could be applied with other types of electric machines

COMPARATIVE ANALYSIS ОF GEOMETRIC DEVIATIONS IN CONTACT MEASURING INSTRUMENTS FOR CONTROL AND LASER CONTACTLESS SCANNING

The factors affecting the dimensional accuracy of 3D scanning using a measuring arm with an integrated scanner and a custom open source 3D printer using FDM technology are researched in this paper, with the purpose of isolating and reducing the sources of errors affecting the results. A consumer 3D printer is analyzed in terms of achieving accurate physical dimensions, consistent shapes, and predictable surface coverage.

OPTICAL GEOMETRIC DESIGN OF SMALL MODULAR CYLINDRICAL GEARS WITH ASYMMETRIC PROFILE

The article presents specific practical solutions for optimal geometric design of evolvental cylindrical gears with an asymmetric profile of cogs in the context of the basic principle of cog interlocking. In order to achieve unknown until now quality indicators, constructions with a minimum number of cogs and a maximum angle of interlocking are shown, which allow for the production of off-polar gears and significantly increase the gear ratio of the differential and planetary mechanisms. In the process of determining the geometrical parameters of the cogwheels of the gear, the “classical approach” is used by analogy with the parameters of the instrument, necessary for the production of the small-module cogwheels of the gear

DEVELOPMENT OF A METHOD FOR CONTACTLESS TEMPERATURE MEASUREMENT IN 3 SPECTRAL RANGES

A 3-spectral method for non-contact temperature measurement has been developed. Three silicon photodiodes were used. The separation of the spectrum is done by optical bandpass filters and beamspliters. It is possible to work in three modes: three-spectral, two-spectral (spectral ratio) and one-spectral. In the first mode, the temperature of objects with an unknown and variable emissivity can be measured. The last two modes give good results respectively for gray bodies and for objects with known emissivity

Marketing research on strategic management of a hotel complex

The goals of a business organization, particularly in the sphere of hotel keeping, of its customers, suppliers, collaborators and the society as a whole may be different and be in conflict. Achieving a balance between different interests, with maximum satisfaction of all parties, depends primarily on its management. The main purpose of the paper is to justify the necessity of introducing a concept for improvement of the strategic management of a hotel complex on the basis of a survey and a qualitative analysis of the hotel product. In order to achieve the goal, several research tasks should be solved: 1.Specifying the basic role of the concepts `management` and `hotel product`; 2.Performing market and product analyzes needed for formulating the main issues; 3.Showing the possibilities of supply updating and formation of a correspondence between the quality of a real hotel product and the one related to desires and interests of real and potential consumers
