Developing a microcontroller-based system for controlling the flywheel motor of high-dynamics spacecraft using Russian-made parts and components made it possible to make statement of the problem of searching control function for a preset rotation rate of the flywheel rotor. This paper discusses one of the possible options for mathematical study of the stated problem, namely, application of structural analysis based on graph theory. Within the framework of the stated problem a graph was constructed for generating the new required rate, while in order to consider the stochastic case option the incidence and adjacency matrices were constructed. The stated problem was solved using a power matrix which transforms a set of contiguous matrices of the graph of admissible solution edge sequences, the real-time control function was found. Based on the results of this work, operational trials were run for the developed control function of the flywheel motor rotor rotation rate, a math model was constructed for the real-time control function, and conclusions were drawn about the feasibility of implementing the results of this study. Key words: Control function, graph, incidence matrix, adjacency matrix, power matrix, microcontroller control of the flywheel motor, highly dynamic spacecraft.

<p>It has been succesfully done the community services activity by using Participatory Action Research (PAR) entitled “Revitalisasi MI Nahdlotusy Syubban dengan pendekatan peran serta masyarakat (PSM) untuk meningkatkan kemandirian sekolah”. The object of this community services is MI Nahdlotusy Syubban Sarimulyo Winong Pati. To explore the problems in this Islamic Boarding School, 3 correlated actions have been formulated. They are Training on School Based Management, PAIKEM Training, and Focus Group Discussions (FGD) addressed to all school management people. The discussions are mainly about the interconnection of the Islamic School (madrasah) with the society in the field of management, feed-back, and school facilities.</p><p>The results are that the teachers already applied PAIKEM in the teaching learning process and the society can directly involved not only in providing the school facilities but also in implementing the control function to the <em>madrasah.</em>As for knowingthe targetandthe quality of graduates, avision, missionand quality standardsarebeing developedin theschool curriculum.</p><p> </p><p>Telah dilakukan pengabdian dengan metode PAR / Participatory  Action Research dengan judul  “Revitalisasi MI Nahdlotusy Syubban dengan pendekatan peran serta masyarakat (PSM) yang bertujuan untuk meningkatkan kemandirian sekolah”. Objek  pengabdian ini adalah MI Nahdlotusy Syubban Sarimulyo Winong Pati.  Untuk mengurai masalah-masalah di madrasah ini di rumuskan 3 tindakan  kegiatan yang saling berkaitan. Pelatihan Manajemen berbasis sekolah (MBS), dan untuk memperjelas komponen MBS dalam proses pembelajaran  diadakan pelatihan  pembelajaran aktif, inovatif, kreatif, efektif dan  menyenangkan (PAIKEM ) sedangkan komponen keuangan, sarpras dan hubungan dengan masyarakat yang merupakan penjabaran dari MBS dirangkum dalam<em> Focus Group Discussion  </em>( FGD) yang di ikuti oleh pemangku kepentingan madrasah meliputi Guru, kepala Sekolah, Yayasan, Komite dan masyarakat secara umum. Dalam FGD ini membahas keterkaitan antara madrasah dengan masyarakat baik dalam bidang manajemen, umpan timbal balik, dan pengadaan sarana dan Prasarana</p><p>Hasilnya guru-guru mulai menerapkan PAIKEM dalam pembelajarannya, dan ternyata masyarakat langsung membuktikan peran sertanya dalam pengadaan dan pembuatan sarana dan prasarana madrasah serta melaksankan fungsi kontrol terhadap madrasah. Sedangkan untuk mengetahui target dan mutu lulusan di susunlah visi misi dan standar mutu lulusan yang mulai  dikembangkan dalam kurikulum pembelajaran sekolah.</p>

The existing approaches to quality assessment, based on ranking and rating, perform a control function but do not give government bodies at various levels, local governments, and public sector organizations the necessary tools to improve their performance. The article is devoted to one of the modern models of quality management in the field of public administration – the European model for improving the activities of public sector organizations through the self-assessment – the Common Assessment Framework (CAF model) and the possibilities of its implementation in Russia.

Optimal boundary control for damping the vibrations in a Mindlin-type beam is considered. Wellposedness and controllability of the system are investigated. A maximum principle is introduced and optimal control function is obtained by means of maximum principle. Also, by using maximum principle, control problem is reduced to solving a system of partial differential equations including state, adjoint variables, which are subject to initial, boundary and terminal conditions. The solution of the system is obtained by using MATLAB. Numerical results are presented in table and graphical forms.

The article realization of NAND FLASH control glueless interface circuit based on FPGA,comparing the advantages and disadvantages of the NAND Flash and analysising the function of control interface circuit. The control interface circuit can correct carry out the SRAM timing-input block erase, page reads, page programming, state read instructions into the required operation sequence of NAND Flash, greatly simplifies the NAND FLASH read and write timing control. According to the ECC algorithm,the realization method of ECC check code generation,error search,error correction is described.The function of operate instructions of the NAND Flash control interface circuit designed in this paper is verified on Xillinx Spartan-3 board, and the frequency can reach 100MHz.
