The paper presents an approach of the blockchain and smart contracts utilization for dynamic robot coalition creation. The coalition is forming for solving complex tasks in industry applications that requires sequential united actions from the several robots. The main idea is that the process is split into two stages: scheduling and dynamic execution. On the scheduling stage, the coalition is defined based on the correlation of existing tasks and robot equipment, and the execution plan is formed and stored in smart contracts. The second stage is the plan execution. During this stage, smart contract controls how each robot solves its sub-task and whether it solves the sub-task due to the planned moment of time. In case of any deviation from the plan, smart contacts will provide a solution for returning to the plan or for changing the coalition composition with new robots and an execution plan. The prototype for execution control system has been developed based on the Hyperledger Fabric platform.

In public are considered the functioning features of mechanism of financing of housing construction through the Construction Financing Fund (CFF), the main investor risks of using CFF and pre-conditions of their origins are defined. It is educed that decision-making about investing using CFF must consist of two stages: on the first stage a bailiff chooses an investment project, initiator and proprietor the Builder, on the second stage the choice of object of investing is made by investor. The principles of choice and the model of choosing the Builder by bailiff are developed; the principles, model and methods of Investor's choice of investment object are offered. The control system was developed to monitor the pre- conditions of risk origins. The suggestions of legislative base improvements in relation to CFF are developed to decrease the risks of investors.

ABSTRAKBiogas merupakan salah satu sumber energi terbarukan yang murah dan berkategori non-polusi. Kebutuhan untuk memonitor serta mengontrol plant biogas bertambah seiring kebutuhan mengoptimalkan stabilitas proses untuk mendapatkan performansi yang tinggi. Monitoring biogas dapat memberikan gambaran keseluruhan proses pembangkitan biogas dan digunakan untuk memprediksi proses fermentasi yang berlangsung. Selain itu, dapat pula meminimalkan gagalnya proses fermentasi dan menghasilkan biogas secara optimal. Dalam penelitian ini proses monitoring dilakukan pada digester dua tahap berbahan dasar ampas tahu dan difokuskan pada pH dan volume biogas yang dihasilkan menggunakan dfrobot sku Sen0160 dan YF-S201 serta solenoid valve sebagai aktuatornya. Hasil penelitian menunjukkan bahwa set point pH 5.3 pada digester asetogenesis dapat dicapai pada hari ke enam untuk tiga percobaan. Dalam digester metanogenesis nilai pH dapat dijaga pada pH 7 ±0.3. Jumlah volume biogas tertinggi yang dihasilkan sebesar 97.2 L.Kata kunci: digester dua tahap, fermentasi, asetogenesis, metanogenesis ABSTRACTBiogas is one of an inexpensive and non-pollution renewable energy source. A requirement for optimization and stabilization of biogas plant affected on the need of monitor and control system in the plant. Biogas monitoring system represents a process in biogas generation and has the ability to predict fermentation. In addition, the system built can be used to control the fermentation process and to minimize the failure of the process. This means the process will produce biogas optimally. In this research, the monitoring system was used on two stages digester using tofu as raw material. pH and biogas volume produced are two focuses in this study using SKU Sen0160 dan YF-S201 as sensors and solenoid valve as an actuator. For three experiments data show, set point for pH (5.3) is achieved at day sixth for acetogenesis digester. For methanogenesis, pH can be maintained at 7 ±0.3. The highest volume of biogas produced was 97.2 L.Keywords: two stages digester, fermentation, acetogenesis, methanogenesis digester

B-lymphocytes normally synthesize small amounts of immunoglobulin, some of which is incorporated into the cell membrane where it serves as receptor of antigen. These cells, on contact with specific antigen, proliferate and differentiate to plasma cells which synthesize and secrete large quantities of immunoglobulin. The two stages of differentiation of this cell line (generation of B-lymphocytes and antigen-driven maturation to plasma cells) are clearly separable during ontogeny and in some immune deficiency diseases. The present report describes morphologic aberrations of B-lymphocytes in two diseases in which second stage differentiation is defective.

Main Components

LaB6 emitters are becoming increasingly popular as direct replacements for tungsten filaments in the electron guns of modern electron-beam instruments. These emitters offer order of magnitude increases in beam brightness, and, with appropriate care in operation, a corresponding increase in source lifetime. They are, however, an order of magnitude more expensive, and may be easily damaged (by improper vacuum conditions and thermal shock) during saturation/desaturation operations. These operations typically require several minutes of an operator's attention, which becomes tedious and subject to error, particularly since the emitter must be cooled during sample exchanges to minimize damage from random vacuum excursions. We have designed a control system for LaBg emitters which relieves the operator of the necessity for manually controlling the emitter power, minimizes the danger of accidental improper operation, and makes the use of these emitters routine on multi-user instruments.Figure 1 is a block schematic of the main components of the control system, and Figure 2 shows the control box.

Polycrystalline Molybdenum

The evolution of dislocation channels in irradiated metals during deformation can be envisaged to occur in three stages: (i) formation of embryonic cluster free regions, (ii) growth of these regions into microscopically observable channels and (iii) termination of their growth due to the accumulation of dislocation damage. The first two stages are particularly intriguing, and we have attempted to follow the early stages of channel formation in polycrystalline molybdenum, irradiated to 5×1019 n. cm−2 (E > 1 Mev) at the reactor ambient temperature (∼ 60°C), using transmission electron microscopy. The irradiated samples were strained, at room temperature, up to the macroscopic yield point.Figure 1 illustrates the early stages of channel formation. The observations suggest that the cluster free regions, such as A, B and C, form in isolated packets, which could subsequently link-up to evolve a channel.
