Rafał Malczewski and Wiadomości

Abstract

The main and most important subject of the article is Rafał Malczewski, who in the interwar period belonged to the elite of the Warsaw intelligentsia. He was successful as a painter, writer, and journalist, collaborating with the most prestigious magazines of the time. The article focuses on Malczewski’s literary output in exile following World War II, after he had settled in Montreal in 1942. Relying primarily on Rafał Malczewski’s correspondence with the poet Jan Lechoń and with the editor in chief of the London publication Wiadomości, the article shows the important role in Malczewski’s life of literary work, which saved him from existential apathy and depression. He collaborated with Wiadomości, one of the most important Polish literary magazines published in exile after World War II. The correspondence between Malczewski’s partner of many years, Zofia Mikucka-Malczewska, and Mieczysław Grydzewski, describes the events surrounding the creation of the special issue of Wiadomości devoted to the writer.

Test characterization of a high performance fault tolerant permanenet magnet machine

“…DC tests involve passing a controlled DCcurrent through the machine coils and recording both the electrical power and internal temperature distribution at thermal equilibrium. Simple prime-move tests rotate the MUT with open-circuit terminal connections or short-circuit connections [5]. The mechanical power required to rotate the MUT under these conditions is recorded as a function of speed.…”

“…The machine-modular 3-phase sets and inverter configurations employed within this prototype is The presented work intends to supplement existing research in the fields of loss-separation and fault-tolerance by exploring the validity of DC, short-circuit and open-circuit characterization to a novel, 4-channel, fault-tolerant machine. Other PM machines have been successfully characterized using simpler prime-mover-only techniques [5] where machine loss and thermal models are calibrated from static DC tests and several prime-mover based dynamometer measurements. It is proposed that, the machine's performance under faulted operation (one or more modules open-circuit or short-circuit) can be extrapolated from the superposition of 'common losses' and 'module-specific' losses measured during these simple tests.…”

“…These may include static electrical tests, dynamometry, calorimetry and sub-assembly evaluation [5], [6], [7]. Some experiments contribute directly to the validation of specification requirements; some develop confidence in the physical system, e.g.…”

“…Iron losses are modelled using well-established techniques as described in [5], [12], [13] and are represented using the trends presented in (2). These losses are dependent upon the operating conditions of the module and therefore are termed "module-specific losses".…”
