Disassembly Planning

Optional disassembly could fulfill the process that parts remove from assembly, which is useful for product maintain, discarding and recycle. Total disassembly planning algorithm can be obtained through proper analysis and evaluation, however that is a difficult process. It is hard to obtain optimal solutions when a huge number of parts are to be removed from an assembly. Exponential explosion during the process of disassembly sequence generation has become a bottleneck for a long time due to over large number of parts included in the product. To solve this problem, an approach based on the modulization is proposed in the paper to generate the disassembly sequence. To partition modules of manufacture equipments, the module identifying method based on multi-rule decision can effectively solve the explosive problem. This method deals with the restrictions and limits of parts before disassembly, hence making disassembly more like the situation of the fact which is limiting the quantity of disassembly combinations, enhancing the efficiency of disassembly and making disassembly much easier.

One of skill becoming goals in study Arabic Ianguage reading skill. Someone wish to reach it must mastering various interconnected knowledge, among others Nahwu –Sharaf. This knowledge becomes burden to one whom studying it especially for beginner. This because the huge number of items exist in Nahwu-Sharaf, so that need very long time to mastering it. This Items effectiveness and time efficiency represent the problem in Nahwu-Sharaf learning. These matters become Taufiqul Hakim’s study materials and concern. Finally he found one new format of efficient and effective method and items in learning Nahwu-Sharaf. The Items compiled in his books entitled “Buku Amtsilati” and his method knows as Amtsilati Method. The application of Amtsilati Method in Nahwu – Sharaf learning emphasize the student activeness, with rather few theory but much practice and also delivering items start from easy then gradually reaching difficult ones.

To ensure uninterrupted power supply to consumers, maintenance of the electrical networks in a working condition is today carried out through the use of a system of preventive maintenance. In the general case such a system allows building equipment repair schedules based on repair cycles for a long time predetermining the list of necessary material and labor resources in advance. However, in practice, the use of this system is rather difficult and not always effective. This is due to the need to change the repair schedule for emergency or urgent repairs taking into account the seasonality of work performed and the organizational structure of the production department of electrical networks and related departments as well as taking into account the specific features of the operation of specific equipment. Taking into account the current pace of development of electrical networks with a steady increase in the number of consumers (which also leads to a complication of the configuration of electrical networks) this is impossible without the use of appropriate mathematics and software that automates the planning processes for the maintenance and repair of electrical networks with a large number of factors. The minimum equipment downtime was taken as the main criterion for optimality, as a factor that largely determines the reliability of power supply. A planning algorithm has been developed that takes into account the ranking of works in order of importance, the possibility of their shift in time and the likely adjustment of the schedule based on the results of assessing the technical condition of the equipment. A method for minimizing the downtime of repair crews by using them in adjacent areas as well as a technique for identifying a set of equipment that may be under repair in the same period of time are proposed.

The term “digitalization” for a long time settled in the agenda of significant events dedicated to education. The education system, fulfilling the adopted program, should prepare a huge number of schoolchildren, students and workers for life with the indispensable use of information and communication technologies. However, often the actual digitalization is reduced either to the digitization of educational materials and documents in educational structures, or to unhindered access to the Internet. If the request for digitalization is addressed to education, then, being in the pedagogical space, it would be reasonable to first determine what and how to teach. The problem of the lack of a reasonable psychological and pedagogical concept of digital learning, which could be used by the subjects of the educational process as a basic one, is raised in the article.

Abstract Motivation Phylogenetic tree reconciliation is the method of choice in analyzing host-symbiont systems. Despite the many reconciliation tools that have been proposed in the literature, two main issues remain unresolved: (i) listing suboptimal solutions (i.e. whose score is ‘close’ to the optimal ones) and (ii) listing only solutions that are biologically different ‘enough’. The first issue arises because the optimal solutions are not always the ones biologically most significant; providing many suboptimal solutions as alternatives for the optimal ones is thus very useful. The second one is related to the difficulty to analyze an often huge number of optimal solutions. In this article, we propose Capybara that addresses both of these problems in an efficient way. Furthermore, it includes a tool for visualizing the solutions that significantly helps the user in the process of analyzing the results.

Proper Analysis

The taxonomy of the Pourthiaea villosa complex, distributed in E Asia, is extremely controversial. The lack of proper analysis and evaluation of the characters used previously may have caused these controversies among taxonomists. The present study is the first comprehensive taxonomic revision of this complex. We have conducted extensive field observations, population sampling, examination of a large number of specimens and subsequent statistical analysis. All morphological characters used in previous taxonomic treatments were analyzed one by one. They include length, breadth, basal angle, and apex of leaf blade, length of petiole, length of pedicel, number of flowers, and density of indumentum on leaves, petiole, pedicel, hypanthium, and branchlets. We found that these characters were extremely variable both within and between populations of this complex. Such variations are continuous or with no statistical support, and there is no correlation between the different characters. Therefore, the characters used in this complex are of little value for species delimitation. As a result of our study, only one species, P. villosa, is recognized, without subdivision. Fourteen names are reduced as new synonyms of P. villosa. In addition, P. villosa is designated as the type of Pourthiaea and 10 lectotypes are designated.
