The paper presents the background and results of numerical simulation and experimental research of a system using auctioneering diodes used to distribute the electrical power between two power converters connected with intermediate circuits in parallel, direct connection. Presented non-isolated power distribution system which utilizes blocking diodes placed in DC branches are used in the selected ship's electrical systems, however, they create problems related to control and handling ground faults. Another issue occurring during the operation of this type of systems is increased heat dissipation while diodes switching. Selected problems related to the operation of experimental system have been identified by means of simulation studies and experiments carried out in a 11 kVA laboratory system and the theoretical basis along with results are provided in the article.

Neutronic performance is investigated for a potential accident tolerant fuel (ATF), which consists of U3Si2fuel and FeCrAl cladding. In comparison with current UO2-Zr system, FeCrAl has a better oxidation resistance but a larger thermal neutron absorption cross section. U3Si2has a higher thermal conductivity and a higher uranium density, which can compensate the reactivity suppressed by FeCrAl. Based on neutronic investigations, a possible U3Si2-FeCrAl fuel-cladding system is taken into consideration. Fundamental properties of the suggested fuel-cladding combination are investigated in a fuel assembly. These properties include moderator and fuel temperature coefficients, control rods worth, radial power distribution (in a fuel rod), and different void reactivity coefficients. The present work proves that the new combination has less reactivity variation during its service lifetime. Although, compared with the current system, it has a little larger deviation on power distribution and a little less negative temperature coefficient and void reactivity coefficient and its control rods worth is less important, variations of these parameters are less important during the service lifetime of fuel. Hence, U3Si2-FeCrAl system is a potential ATF candidate from a neutronic view.

With the development of our country electric power enterprise, closed-loop pour load operation has become increasingly frequent in power distribution network, the resulting circulation problems affect the safe operation of power grid. The calculation method of system is used by BX type solution fast decomposition method and it is very suitable for distribution integration, by the method we can calculate the steady state current and transient current of closed-loop. It also provide accurate current analysis and control. With analysis of examples, finally indicates that the method can offer good for dispatch staff for closed-loop operation decision support, and it has a certain guiding significance.

The system of collaboration between design and manufacturing is proposed in order to meet the precision forging manufacturing. The configuration of the system and functions are studied and analyzed in detail. The system integration mode based on PDM (Product Data Management) is put forward. Application systems around the process of collaboration between design and manufacturing can be integrated seamlessly by integration mode. And two key enable technologies are analyzed in detail. Model association method based on WAVE technology is used to implement design of precision forged die. The work model and data structure based on the collaboration system is studied. Finally, an application engineering system is developed and a case study is given to demonstrate the above ideas in the environment of aero-engine manufacturing enterprise.

For youth under child welfare, transitioning out of residential care and reintegrating into their community can be a difficult process. This may be especially true for Inuit youth who, because they are away from their communities, cannot develop networks and relationships that would provide a secure place for their development as an adult and as a community member. The objectives of this study were to document how transition out of care is addressed in a residence specialized for Inuit youth under government care, and to explore, from the perspective of residential managers and staff, what factors facilitate or create obstacles to successful transition. Interviews were conducted to discuss the transition of 11 youth from residential placement back into communities. The criteria used by managers and staff to describe transitions mostly focused on the behaviours of the youth and the ability to create and implement a plan. Are current theme was the importance of continuity and connections with family, staff, and culture. Various measures were put into place around the current system of care in order to facilitate continuity and connections to respond to the cultural and personal needs of youth. To enhance the “cultural competence” of care, we suggest that: (i) criteria for successful and unsuccessful transitions be determined with youth, families, and communities; (ii) that Inuit representation in care be increased; and (iii) that measures be taken outside the current system of care to encourage shifts in power distribution.
