Inspection Task

Inspection and exploration represent a challenging domain in the field of robotics because of the hazardous and limited workspace to which the robots have to adapt and because of the reduced ability to monitor and acquire data about the inspected environment. A pipeline inspection robot must ensure sufficient traction force to pull its tether cable and other equipment while travelling inside a pipeline to complete inspection, maintenance, and repair tasks. This paper presents the design of three minirobots with adaptable structure for in pipe inspection and the experimental determination of their traction force. To measure the traction force of the minirobots, the Xplorer GLX digital measuring device was used.

Currently, in order to ensure the required fault-proof level of technological processes in agricultural production, the following strategies among the main ones: afterfailure, planned systematic and a mixed electrical equipment maintenance and repair strategy. The pervasion of information technology in this segment was not widespread. Application of information technologies in conjunction with implementation of risk-oriented strategy is one of the promising directions of electrical equipment maintenance optimization, yet requires adaptation to sectoral characteristics of agricultural production. The article describes the problem of determining the optimal conditions for adjusting the frequency of maintenance and repair of electrical equipment on the basis of risk-oriented approach. To solve this problem, the equation of annual costs for maintenance and repair of electrical equipment was drawn up taking into account the parameter of its failure risk. The relationship between the change of relative risk and the service frequency was established; based on it, the ranges of frequency adjustment of maintenance and ongoing repair were determined.

Support the presence of the KRI elements it needs other supporting means such as Fasharkan (Maintenance and repair facilities) that serve as a supporter of logistics, especially repair and maintenance of KRI. The closest area of Fasharkan from the Sea of North Natuna today is Fasharkan Mentigi Lantamal IV Tanjung Pinang is approximately 510 Nm surely will be an obstacle when the presence of the KRI element in the North Natuna Sea operating area is shaken because The distance of Fasharkan from the distant waters of North Natuna to carry out maintenance and repair. So it is necessary to one more location of Fasharkan to support the operation of the KRI elements in the territorial waters of North Natuna so that the operation of the KRI elements can be carried out well. In the selection of Fasharkan location has several factors that must be considered so that categorized have multicriteria in the election. So to accommodate Multicriteria divided into Technical Requirements & Operational Requirements Then use the Fuzzy method MCDM (Multi-Criteria Decision Maker). Technical Requirement consisting of earthquake hazard, distance field operations (distance operations and ALKI 1), distance downtown (the distance of the center of the government and the settlement), and hydrography (depth, tidal, and speed of currents). While the Operational Requirement consists of the influence of other countries, threats (outside state threat and community conflicts), access transportation (military port and airport), supporting facilities (water facility, communication facilities, Electric facilities, transport facilities and sea flows), as well as operational costs. For the alternative location of Fasharkan consists of Lantamal XII Pontianak, Ranai Navy Base, and Tarempa Navy Base.Of the three alternative locations obtained the best alternative to the location of Fasharkan is Ranai Navy Base with the highest rank of 0.403 then Lantamal XII Pontianak with a value of 0.302 and Tarempa Navy base with a value of 0.295.

Standard Calculation

Современные промышленные предприятия оснащаются дорогостоящим и уникальным оборудованием. В процессе эксплуатации оно теряет свои технико-эксплуатационные качества главным образом из-за износа и разрушения отдельных деталей, поэтому снижается точность, мощность, производительность и другие параметры. Для бесперебойной работы оборудования с заданными точностными характеристиками требуется систематическое техническое обслуживание, текущие и капитальные ремонты. Текущий ремонт - это ремонт, осуществляемый для восстановления работоспособности оборудования и состоящий в замене или восстановлении его отдельных составных частей. Капитальный ремонт - ремонт, выполняемый для обеспечения исправности и полного или близкого к полному восстановления ресурса оборудования с заменой или восстановлением любых его частей, включая базовые (под базовой понимают основную часть оборудования, предназначенную для компоновки и установки на нее других составных частей). Послеремонтный ресурс оборудования должен составлять не менее 80 % ресурса нового оборудования. Затраты на капитальный ремонт осуществляются предприятием за счет производимых им амортизационных отчислений. На рыночной стоимости оборудования сказывается проведение капитального ремонта: под влиянием ремонта рыночная стоимость оборудования резко повышается. Предлагается алгоритм расчета экономических нормативов для планирования технического обслуживания и ремонта оборудования и рыночной стоимости оборудования, а также блок-схема расчета экономических нормативов.

Structure Of Production

In order to increase the efficiency of the operation of motor transport enterprises, the structure of production units for maintenance and repair of cars should be determined by the scope of work, taking into account the cost of implementation of the unit labor complexity of works. In case of inappropriateness of creating or maintaining an MTE of separate production units, maintenance and repairs of cars should be carried out at specialized service centers. Therefore, with the improvement of production units of motor transport enterprises structure, it is important to provide economically expedient delivery distances for maintenance works and repair of cars by co-operation in car service companies, which provide relevant services. The determination method of economically expedient distances of cars delivery and repair fund for car service companies is given. The cost of cars delivery and repair fund for 1 km to the car service companies or other motor transport enterprises (MTE), which accounts for 1 man-hour of labor-intensive maintenance and repair is determined. The economically expedient delivery distances for maintenance and cars repair by cooperation in car service companies are determined. The results of the calculations show that for taxi-driven MTE economically appropriate in modern conditions of distance of delivery of cars to perform maintenance-1 and maintenance-2 are close to those recommended in literary sources. For truck and bus MTE the corresponding delivery distances for maintenance-1, maintenance-2 performance, ongoing repairs are significantly lower. When performing diagnostic works D-1 and D-2, most of the the district works of the ongoing repair, the economically reasonable distances of delivery to the car service companies are obtained that substantially exceed the recommendations given in the scientific literature.

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Sn 1987A

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.
