Study on the characteristics of electromagnetic noise of axial flux permanent magnet synchronous motor
No full textThe normal electromagnetic force distribution in stator system of axial flux permanent magnet synchronous motor (PMSM) has been thoroughly analyzed in this paper. The main composition of force wave causing vibration and noise has been proposed, and at the same time a calculation method of stator natural frequency of axial flux PMSM has been raised. Through this method electromagnetic force wave, natural frequency, vibration response, and electromagnetic noise of a 15 kW axial flux PMSM with 22 poles and 24 slots have been calculated; calculations and measured values are consistent by comparison. The noise sources of axial flux PMSM have been found in this paper, which provides the theoretical support for the suppression of electromagnetic noise of axial flux PMSM. © 2014 Wei Wang et al
Pancorius candidus Wang & Wang 2020, sp. nov.
No full textPancorius candidus sp. nov. Figures 1–13, 23 Etymology. The specific name is from the Latin word candidus (bright), adjective, and refers to the bright coloration of live specimens. Diagnosis. The male of the new species closely resembles P. submontanus Prószyński, 1992 (Prószyński 1992: figs 116–117) known from West Bengal, India and P. wangdicus Żabka, 1990 (Żabka 1990: figs 16–18) from Bhutan in the palpal structure, but can be distinguished by the obtuse tip of the RTA in retrolateral view (Fig 7), which is pointed in P. submontanus and P. wangdicus. The female somewhat resembles P. goulufengensis Peng, Yin, Yan & Kim, 1988 (Peng et al. 1988: figs 4–6) from Hunan, China in having a paired pocket, but differs in: 1) the copulatory ducts are anterior-lateral to receptacles vs posterior to receptacles in P. goulufengensis; 2) the copulatory openings are located anteriolaterally vs posteriolaterally in P. goulufengensis; and 3) the receptacle is almost round vs oval in P. goulufengensis.(Figs 8–9).

Pancorius wesolowskae Wang & Wang 2020, sp. nov.
No full textPancorius wesolowskae sp. nov. Figures 14–23 Etymology. The new species is named in honour of Prof. Helena Wanda Wesołowska (Wrocław, Poland), who has contributed an enormous amount to studies of the Palaearctic and African jumping spider fauna. Diagnosis. The male of the new species closely resembles P. wangdicus (Żabka 1990: figs 16–18), known only from the male from Bhutan, but can be distinguished by: 1) RTA is shorter and relatively blunt (Figs 19–20) vs more elongated and pointed in P. wangdicus; 2) the lower margin of the prosoma is uncovered (Fig 14) vs covered with white seta bands in P. wangdicus. The female resembles P. cadus Jastrzębski, 2011 (Jastrzębski 2011: figs 7–8) in general epigyne structure, but can be distinguished by the copulatory openings, which are slit-shaped in the new species rather than C-shaped in P. cadus, and by the distance between the copulatory ducts, which is less than the distance between receptacles in the new species compared to more than twice greater than the distance between receptacles in P. cadus.(Figs 21–22). Description. Male (Holotype, SCAU-GZ-20130508001). Total length 6.30, PL 3.36, PW 2.82, OL 2.94, OW 1.98. Eye sizes: AME 0.76, ALE 0.41, PME 0.14, PLE 0.37; AER 2.43, PER 2.19, EFL 1.50.

Prosoma dark-brown, broadened, with a central red-brown area, and covered with sparse white setae behind the PLEs. White setae around the AER. Clypeus brown, covered with white setae centrally.

Opisthosoma dark grey, covered with dense translucent yellowish setae, sparsely scattered with bristles. Dorsum with a longitudinal light broad central band followed by several pairs of inclined extensions. Venter light grey, with four dotted lines. Spinnerets dark brown to greyish-yellow. Leg I fairly strong, patellar dorsum and tibia with cluster of brush-like dark setae, and all legs with spines. Palp: tibia slightly longer than 1/3 cymbial length. RTA almost triangular, blunt and short. Tegulum with a domed lobe, extended from the proximal margin. Embolus thick, basally expanded into a keel shape, and tapered to a blunt tip. Female (Paratype, SCAU-GZ-20130508002). Total length 7.93, PL 3.40, PW 2.85, OL 4.53, OW 3.44. Eye sizes: AME 0.77, ALE 0.45, PME 0.13, PLE 0.39; AER 2.53, PER 2.25, EFL 1.67. Clypeus height 0.24. Legs: I 5.57 (1.74, 0.85, 1.44, 0.81, 0.73); II 5.32 (1.78, 0.93, 1.16, 0.75, 0.70); III 6.88 (2.49, 0.88, 1.44, 1.14, 0.93); IV 6.57 (2.21, 0.71, 1.43, 1.43, 0.79). Leg formula: 3412. Habitus similar to that of male. Leg I more slender than male, without brush-like dark setae. Epigyne: epigynal plate posteriorly widened, anterior margin notably convex. Copulatory openings slit-shaped. Epigynal pockets paired, slightly wide than long, located posteriorly, relatively close to each other. Copulatory ducts strongly sclerotized, stretched posteriorly. Receptacles almost round, obviously separated from each other by less than 1/2 their diameter. Fertilization ducts originated from middle of inner sides of receptacles. Type material. Holotype ³: CHINA: Guizhou: Jiangkou County, Machaohe of Fanjingshan National Nature Reserve, 27°52’55.67’’N, 108°47’54.83’’E, 615 m a.s.l., leg. Cheng Wang, Ming-yong Liao & Bo Yu, 8.V.2013 (collected by beating shrubs) (SCAU-GZ-20130508001). Paratype: Same data as holotype, 1♀ (SCAU-GZ-20130508002). Distribution. Known only from the type locality. Habitat. The specimens were collected from a low altitude mountain region, where the habitat was relatively undisturbed. Based on the authors’ experience during fieldwork, species of the genus Pancorius is nearly restricted to habitats that have not been severely influenced by human activities, and potential distribution of the new species will be possibly concentrated in the regions that share a similar environment with the type locality, i.e. humid marginal areas of mountain forests.Published as part of Wang, Wei-Hang & Wang, Cheng, 2020, Description of two new species of the jumping spider genus Pancorius Simon 1902 (Araneae: Salticidae) from Southwest China, pp. 354-362 in Zootaxa 4899 (1) on page 359, DOI: 10.11646/zootaxa.4899.1.17, http://zenodo.org/record/440061
Exploring the eudaimonic game experience through purchasing functional and nonfunctional items in MMORPGs
No full textThe consumption of virtual items and other forms of in‐game content is rapidly increasing in the Massively Multiple Player Online Role‐Playing Games market. While psychological need satisfaction obtained through purchasing virtual items to achieve hedonic game experience remains at the center of the debate, most of these studies neglect the eudaimonic game experience and do not differentiate between the psychological experiences from functional items and nonfunctional items. Our research employs the eudaimonic game experience perspective to explore the psychological need satisfaction individuals achieve through purchasing functional and nonfunctional items. From interviews with 25 players, a novel finding is that, while competence, autonomy, relatedness, and purpose in life contribute to one's eudaimonic game experience, each psychological need has its own unique dimensions for different virtual product types. Competence and purpose in life are needs driven by two factors: inner‐directed consumption intention, emphasizing aspiration for authenticity and personal growth; and other‐directed consumption intention, focusing on motivations that elicit, for example, positive responses from others and receiving social awards. Such results are only apparent for functional items but not for nonfunctional items. In contrast, autonomy and relatedness are needs explained by one's inner‐directed consumption intention, across both product types
