Solving the More Difficult Aspects of Electric Motor Thermal Analysis in Small and Medium Size Industrial Induction Motors
No full textWith the ever-increasing pressure on electric motor manufacturers to develop smaller and more efficient electric motors, there is a need for more thermal analysis in parallel with the traditional electromagnetic design. Attention to the thermal design can be rewarded by major improvements in the overall performance. Technical papers published to date highlight a number of thermal design issues that are difficult to analyze. This paper reviews some of these issues and gives advice on how to deal with them when developing algorithms for inclusion in design software

Evolution and Modern Approaches for Thermal Analysis of Electrical Machines
No full textIn this paper, the authors present an extended survey on the evolution and the modern approaches in the thermal analysis of electrical machines. The improvements and the new techniques proposed in the last decade are analyzed in depth and compared in order to highlight the qualities and defects of each. In particular, thermal analysis based on lumped-parameter thermal network, finite-element analysis, and computational fluid dynamics are considered in this paper. In addition, an overview of the problems linked to the thermal parameter determination and computation is proposed and discussed. Taking into account the aims of this paper, a detailed list of books and papers is reported in the references to help researchers interested in these topics
Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors
No full textThis paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance motors. It is illustrated for switched-reluctance, synchronous-reluctance, induction, brushless AC, brushless DC, interior PM and commutator motors. The calculated flux-MMF diagrams for motors with the same electromagnetic volume, airgap, slotfill, and total copper loss are shown and are used to compare the low-speed torque and torque ripple performance. The motor designs used were reasonably optimized using a combination of commercially available motor CAD packages and finite-element analysis
bstaton1/LKG-RRS: Updated Final Release - For Use with More Current Package Versions
No full textThis is an updated archive of the analysis used for the GL(M)M analyses found in the manuscript entitled Improved productivity of naturalized spring Chinook salmon following reintroduction from a hatchery stock in Lookingglass Creek, Oregon by H.M. Nuetzel, P.F. Galbreath, B.A. Staton, C.A. Crump, L.M. Naylor, and G.E. Shippentower, accepted for publication in the Canadian Journal of Fisheries and Aquatic Sciences (DOI: 10.1139/cjfas-2022-0114).
The update is needed to remain current with a breaking change made in one of the critical R packages used in our analyses: glmmTMB . We used glmmTMB version 1.0.2.1 at the time of submission/review/publication, but it contained a bug (see #634). We implemented an ad-hoc fix so the results published in the manuscript are correct. However the fix we implemented will now break the analysis for users of glmmTMB >=v1.1.5 (most current on CRAN at time of writing) without their knowledge. Please see here for a complete description of the bug that was present in the old version in the context of our analysis, the solution we implemented to ensure valid inference at the time of publication, and an illustration that the fix we implemented is no longer needed with glmmTMB >=v1.1.5 (and indeed causes the wrong inference).
This version of the analysis code has the ad-hoc fix removed, thus, it is of critical importance that you use glmmTMB >= v1.1.5 to reproduce our results. This version has been tested with R v4.2.2 and the versions of the packages listed in the repo README and completely replicates the results published in the article
Assays for membrane and intracellular signalling events
No full textThe aims of this book are to provide workers in the field of angiogenesis with a critical analysis of the various methods used to study angiogenesis. As such, I would suggest that this chapter should present less specific data on caveolae etc and instead place a greater emphasis on the actual techniques used to study the signalling pathways, including a discussion of their strengths and weaknesses. Please can you also add a few more of the commonly used methods that look at how signals cross the membrane, measuring protein phosphorylation, microarrays, RT-PCR etc
Beyond broaching: Existential meaning making of Blackness within therapeutic work
No full textThis integrated literature review explores the mental health field’s contribution towards the subjugation of Black people through the means of researching human existence that affirmed white supremacy and bolstered the dehumanization of Blackness. This paper also explores how this negligent behavior on the part of the mental health field trivialized the deep pain and suffering experienced by Black people and provided the means to further dehumanize Blackness. The author provides frameworks to better understand the existential trauma experienced by the Black collective due to racism being embedded in societal narratives and history with the help of the mental health field. The author also introduces Black existentialism as a theoretical avenue for the mental health field to begin undoing the pervasive white supremacist narratives it established while also liberating and centering Blackness within the therapeutic work
Biological and clinical implications of recruitment of stem cells into angiogenesis.
No full textEmerging evidence suggests that bone marrow may represent a reservoir of endothelial progenitor cells (EPCs), which could contribute to postnatal tissue vasculogenesis. These cells can be mobilized to the circulation through the action of specific angiogenic factors and contribute to neoangiogenic processes. The level of circulating EPCs has been proposed as a surrogate biologic marker for vascular function suggesting that EPCs may have a role in maintenance and reparative processes and in tumor development. The phenotypic characterization of EPCs remains controversial because of the lack of specific endothelial markers and functional assays. The most promising areas of current research focus on the investigation and understanding of the role EPCs in cardiovascular disorders and tumors in order to develop therapeutic strategies that can modulate EPC trafficking and function
