PT United Tractors Tbk Jakarta workshop held a lot of Machine Inspection Programs for Komatsu units. During the implementation of the Machine Inspection Program (PPM) the machine inspection program is one part of the maintenance that is carried out periodically to obtain accurate data on the condition of the equipment at the time by carrying out checks and adjustments using measurement methods and diagnostic instruments The use of a pressure gauge is still using manual and has a measurement distance that is still limited, if workers or mechanics are not equipped with sufficient knowledge then the pressure gauge will have the potential for error in use and the selection of a pressure gauge is not appropriate to the pressure gauge directly connected to the hydraulic pressure through the hose then the work process ppm is not enough 1 manpower. Therefore it is necessary to modify a digital pressure gauge that has a wide range of scales, in addition a wireless connection is needed to enable the operation of the unit and measurements are made 1 manpower and Bluetooth is one of the right choices in addition to the reach can be met in an application not too difficult so that readings measurement results can be connected directly via mobile.

Entry of non-alphanumeric information into computer graphics systems is frequently accomplished by moving a drawing implement over the surface of a digitizing tablet. These tablets are commercially available in a wide range of sizes. Therefore, an important question from both ergonomic and economic standpoints concerns the optimum size for the digitizing tablet. To answer this question, models of human movement control were applied to the graphic operator's task. An experiment was conducted to obtain appropriate model parameter values and to empirically evaluate the resulting predictions of the generated models. A combination of task analysis and movement control modelling thus allowed selection of an optimum digitizing tablet size for a range of computer-graphics entry tasks. Details and results of this methodology will be presented.

Lichens are an iconic example of symbiotic systems whose ecology is shaped by the requirements of the symbionts. Previous studies suggest that fungal (mycobionts) as well as photosynthesizing (phycobionts or cyanobionts) partners have a specific range of acceptable symbionts that can be chosen according to specific environmental conditions. This study aimed to investigate the effects of climatic conditions and mycobiont identity on phycobiont distribution within the lichen genera Stereocaulon, Cladonia, and Lepraria. The study area comprised the Canary Islands, Madeira, Sicily, and the Aeolian Islands, spanning a wide range of climatic conditions. These islands are known for their unique and diverse fauna and flora; however, lichen phycobionts have remained unstudied in most of these areas. In total, we genetically analyzed 339 lichen samples. The phycobiont pool differed significantly from that outside the studied area. Asterochloris mediterranea was identified as the most abundant phycobiont. However, its distribution was limited by climatic constraints. Other species of Asterochloris and representatives of the genera Chloroidium, Vulcanochloris, and Myrmecia were also recovered as phycobionts. The selection of symbiotic partners from the local phycobiont pool was driven by mycobiont specificity (i.e., the taxonomic range of acceptable partners) and the environmental conditions, mainly temperature. Interestingly, the dominant fungal species responded differently in their selection of algal symbionts along the environmental gradients. Cladonia rangiformis associated with its phycobiont A. mediterranea in a broader range of temperatures than Stereocaulon azoreum, which favors other Asterochloris species along most of the temperature gradient. Stereocaulon vesuvianum associated with Chloroidium spp., which also differed in their temperature optima. Finally, we described Stereocaulon canariense as a new endemic species ecologically distinct from the other Stereocaulon species on the Canary Islands.

The article deals with increasing the efficiency of scientific project management in higher military educational establishments by introducing the method of distribution of research works among the teams of performers of scientific projects of higher military educational establishments, analyzes the load of scientific and pedagogical workers of typical structural units of higher educational establishments of higher educational establishments. Actions of the functional leader in the selection of the team of executors of the scientific project. Specificity of scientific tasks in the military field is the need to overcome the uncertainties caused by the unpredictability of the enemy during combat. The complexity and multidimensionality of the problem of planning and managing the scientific and technical activities in the security and defense sector necessitate the improvement of existing planning and management mechanisms in the Armed Forces of Ukraine. Management activities of functional leaders is one of the important factors for the success and quality of scientific tasks. In the teaching and research processes of higher military education there is a wide range of management entities. The content and scope of managerial functions of heads of departments, faculties and departments are defined in the relevant charters, guidelines and instructions. However, it is very difficult to identify the quantitative weight of each institution of management of the scientific-pedagogical system of higher education institutions and its structural units. The order of performing management functions during certain periods of activity is worked out by each entity, mainly independently, on the basis of personal experience, the choice of forms, methods and means of influencing the management object is, for the most part, a creative process. One of the important aspects of the implementation of a scientific project that depends on the end result is the selection of the "right" team of project executors and the project resource, namely: specialists in the field of research, motivated by the result, able to achieve it by their competence, not overloaded with other work , plus - comprehensive security of the project. In order to increase the effectiveness of management activities, to apply the management of the institution (the chief and his deputy for scientific work) by the apparatus, to qualitatively evaluate and make the right management decisions at the stage of appointment of the project manager and the team of executors of the scientific project, to determine the resource base and limitations in this particular scientific project, this technique is proposed. Management of scientific projects in all phases of their implementation - from order to implementation, is a priority direction of increasing the efficiency of the system of scientific and scientific-technical activity of the Armed Forces of Ukraine. The implementation of the algorithm of selection of the team of executors of the scientific project is an effective mechanism for optimizing the decision-making process by functional managers in the early stages of scientific projects.

A variety of natural-production conditions, which is necessary to conduct logging activities largely complicates the choice of forest machines for each individual company in the industry having logging sites in its composition. Depending on many natural and production conditions such as: slope, bearing capacity of soils, ambient temperature, maximum investments, etc., and the wide range of forestry equipment on the market, engineering divisions of the company solving a problem about the purchase of new or replacement of lost its performance machines are more and more difficult to make the right choice. This work presents a methodology for forming the system of forest machines with the natural and production conditions in a convenient form, not requiring special expert knowledge from the field of mathematical modeling or other areas of science. According to the methodology the first step is selection of basic machine and performing the first major operation in felling trees, then switch to the auxiliary machines which are linked to the underlying performance, to reduce the number of in-process stock. Selection of basic and auxiliary machines is provided that candidates and excludes important indicators. If in the process of selecting the logging machine does not meet the screening criteria for excluding indicators then it does not participate in the selection. Significant index can be neglected in case of discrepancy of candidates to stated requirements. The performance of the model was tested on the example of harvesting sites of the enterprises of the Krasnoyarsk region in spring 2016. In the course of the experiment the system of forest machines, meeting the required selection criteria, was obtained.

In the paper, selected problems that are related to the measurements of thermal parameters of power MOSFETs that are placed on a common heat sink are analysed. The application of the indirect electrical method, the contact method, and the optical method in measuring self and mutual transient thermal impedances of these transistors is presented. The circuits that are required to perform measurements are presented and described. The errors of measurements are assessed for each of the considered methods. In the case of the indirect electrical method, an additional influence of the selection of a thermo-sensitive parameter and the function approximating thermometric characteristics on the measurement error are taken into consideration. The measurement results of the thermal parameters of the investigated transistors that were obtained using the considered measurement methods in various supply conditions are presented and discussed.
