14. The Committee of Permanent Representatives:

The Committee of Permanent Representatives (Coreper) originated as a diplomatic forum to meet regularly and prepare meetings of the Council of Ministers. It quickly and quietly evolved into a locus of continuous negotiation and de facto decision-making, gaining a reputation as ‘the place to do the deal’. This reputation is based on insulation from domestic audiences and an unrivalled ability to make deals stick across a range of issue areas and policy subjects. Most importantly, Coreper spotlights the process of integrating interests in a collective decision-making system with its own organizational culture, norms, and style of discourse. In actual operation, the Committee has much to offer institutional theorizing, as multiple ‘logics’ of action are discernible and often complexly entwined.

Natural Frequency and Resonance Study of FGM Turbo-Machinery Blade Using Campbell Diagram

Turbo machinery rotating blades are a vital component of aero-engines for transferring the energy of gas flow to kinetic energy. Rotating turbo-machinery blades are prone to fail under working fields with high temperature, high speed, high pressure and resonance of blades with prime engine. Vibration of the turbo-machinery blades need to be studied carefully for safe and reliable operation of the engine. Thermal barrier coatings (TBC) layers are used to protect the blade metal at higher operating temperature though these can be plagued due to phase instability, thermal instability and adherence problems. TBCs also tend to spall due to thermal expansion mismatch with the super alloy substrate or because of erosion/impact caused by particles in the high-velocity combustion gases. Functionally graded materials (FGMs) are a relatively new class of materials that can solve these problems in high-temperature environments and can be considered as potential material for making gas turbine blades. Unlike composite materials the functionally graded materials (FGMs) are free from delamination and debonding and have the ability to withstand high temperature without TBC coatings. In this present study natural frequency of the FGM turbine blade for various rotational speeds during actual operation is determined using finite element technique. As the aero-engine is complex in nature therefore harmonic resonance can always occur in the aero-engine system and it is difficult to determine the natural frequency at varying speed during actual operation. The chances of failure of the blade also increase because of harmonic resonance. Hence, the resonance property is required to investigate of the FGM blade in details. Various rotational speed and operating temperature is considered to determine the natural frequencies of the blade. The resonance studies for each case are performed using the Campbell diagram. Resonance margin is calculated for each case and safe operating speed is determined. This study could serve as ready reference for safe operation of turbo-machinery engine considering FGM blade for specific range of engine speed.

Analysis and Research on Ice Storage and Water Storage Air Conditioning System of an Electric Power Building

The air conditioning system of ice storage and water storage has been applied in many practical projects. This paper introduces the air conditioning system form of Fuyang Electric Power Dispatching Building. The design condition of cold and heat sources and its transmission and distribution system is also introduced. In addition, this paper also collects and analyses the data of the chillers in actual operation. The results show that the system runs steadily and accords with the design conditions.

Interdependence of constructive and settlement schemes of the building

At the design stage is very important for the formation of the reliability of any building is the stage of formation of the design model of the building, which is the basis for the construction of its load-bearing elements. The main at this stage is the adequacy of the adopted calculation model to the actual design scheme. A very important condition for assessing the actual operation of the building is to take into account the joint work of the upper part of the building (frame) with the foundations and soil base. The article examines some problems in the operation of structures, which are related to the choice of design models used in their design, on the example of a 9-storey parking lot built in the early 2000s on Pobeda Square in Kyiv. Chi-rural studies using PC LIRA-CAD analyzed the impact of joint work of the framework and foundations on the efforts at their contact. It was found that: - the impact of joint work of the frame and foundations is significant and is manifested only within a few lower floors of the frame; - taking into account the nonlinear operation of reinforced concrete structures in most cases significantly reduces the calculated forces at peak points - concentrators; - in the design process it is necessary to consider and analyze the variant design solutions of the system.

Numerical Simulation of the Effects of Oil Gun Location and Oil Feed Rate on Coal Ignition and Burner Wall Temperature in a Tiny Oil Ignition Burner

To solve the overheating problem of tiny oil ignition burners’ walls during the firing-up process in a 330 MWe tangentially pulverized coal-fired boiler, a numerical model of a tiny oil ignition burner was carefully built considering combustion, gas–solid flow, and heat transfer. Then, the burner location and oil feed rate were optimized based on the model to prevent the burner’s walls from overheating. The effects of the oil gun extension distance (100, 200, 300, 400, 500 mm) and oil feed rate (160, 140, 120, 100, 80, 70, 60 kg/h) on coal ignition performance and burner wall temperature were carefully investigated. The simulation results showed good agreement with the measured results. The results indicated that decreasing the oil gun distance within the burner diminished the flame length of the co-combustion of oil and pulverized coal, thus lowering the burner wall temperature. Decreasing the oil feed rate appropriately could also reduce the burner wall temperature without influencing the ignition performance. Considering both ignition performance and burner wall temperature, an extension of 400 mm of the oil gun location and an oil feed rate of 160 kg/h were successfully applied to the actual operation without adverse effects. Moreover, it is suggested to move the temperature monitor points from the burner upper wall to the burner side wall.

Hip Lift Transfer Assistive System for Reducing Burden on Caregiver’s Waist

In Japan, the aging population is expected to increase the number of elderly people in the future. The purpose of this study was to develop a hip lift transfer assistive system to improve the QOL of elderly living and to prevent back pain for caregivers. We extracted the impediment factor and the necessary scene for the assistance, decided on the transfer process from the wheelchair in the toilet, and considered the reduction method of the burden based on the quantitative evaluation of the caregiver’s lumbar burden and developed the device. Then we proposed the algorithm of the system by grasping the behavior and lumbar burden characteristics at the time of using the hip lift transfer assistive system by the developed device in which the proposed support algorithm of standing seating assistance operation is implemented in the actual use environment. Through the assistive movement evaluation experiment and the actual operation in the toilet, we have verified that the use of this device can reduce the caregivers’ lumbar burden below the standard value (3400 N) and have proved the effectiveness of the proposed transfer assistive system.

Law's Ability to Further the "Menstrual Movement"

The current menstrual movement calls for overcoming the cultural stigma associated with menstruation, achieving “menstrual equity,” and ending “period poverty.” The stigma the movement seeks to address is that menstruation is seen as taboo, unclean, and impure. The movement’s aims are twofold: First, it wants to increase awareness of menstruation and remove discrimination against those who menstruate, thus achieving menstrual equity. Second, it intends to provide greater access to menstrual hygiene products (“MHPs”), particularly for homeless and lower income people, thus eliminating period poverty. To achieve these goals, the movement is advocating to legislatively eliminate the “tampon tax” and increase access to MHPs in prisons, homeless shelters, and schools. It also supports lawsuits challenging the constitutionality of the tampon tax. Advocates view these legal changes as instrumental in furthering the goals of equity and access to MHPs that underlie the movement. This Essay discusses whether the two major legislative changes the movement advocates—repeal of the tampon tax and providing MHPs in schools for free—will actually achieve the movement’s goals. The Essay begins by explaining how these legal changes, in theory, are meant to address menstrual equity and period poverty. It then explores the operational limits to, and expressive benefits of, these legal proposals. The Essay concludes that the expressive function of demanding these legal changes, and sometimes achieving them, plays a more significant role than the laws’ actual operation in reaching the movement’s goals.

A Critical Review of Data-Driven Transient Stability Assessment of Power Systems: Principles, Prospects and Challenges

Transient stability assessment (TSA) has always been a fundamental means for ensuring the secure and stable operation of power systems. Due to the integration of new elements such as power electronics, electric vehicles and renewable power generations, dynamic characteristics of power systems are becoming more and more complex, which makes TSA an increasingly urgent task. Since traditional time-domain simulations and direct method cannot meet the actual operation requirements of power systems, data-driven TSA has attracted growing attention from both academia and industry. This paper makes a comprehensive review from the following four aspects: feature extraction and selection, model construction, online learning and rule extraction; and then, summarizes the challenges and prospects for future research; finally, draws the conclusions of this review. This review will be beneficial for relevant researchers to better understand the research status, key technologies, and existing challenges in the field.
