Hedonic Prices and House Numbers: The Influence of Feng Shui
No full textIn contemporary practice, feng shui incorporates a wide range of concepts considered to affect a person’s luck. These include traditional ideas about site selection and building design, as well as newer beliefs about the “luckiness” of certain numbers. Focusing on an area with a relatively high percentage of Chinese households in Auckland, New Zealand, this paper uses hedonic price analysis to investigate whether house values are affected by lucky and unlucky numbers. Sales transactions for 1989 to 1996 are used in this analysis. The results demonstrate that lucky house numbers are capitalised into house values.Feng shui, hedonic price model, lucky, New Zealand

No full textReevesia napoensis H. Z. Feng & Y. Feng Huang sp. nov. (Figs. 3, 4 & 5) Type: — China. Guangxi, Napo Country, Laohutiao Nature Reserve, 700m, 3 August 2014, Y. Feng Huang & H. Z. Feng 70069 (holotype GXMI, isotype IBK). Diagnosis: — Differs from R. rotundifolia and R. orbicularis by cordate, 7-veined leaf base; 3-bracts (two linear and one elliptic-ovate); 4-lobed calyx and the glabrous petals. Description:—An evergreen tree, young branchlets terete, glabrous. Leaves petiolate, petiole 3–17 cm, terete, sparsely stellate puberulent when young, glabrous at maturity, leaf blade orbicular or ovate–orbicular, 9–40 × 8–27 cm, leathery, both sides with sparse yellowish stellate pubescence only on veins, otherwise glabrous, basal veins 7, venation adaxially conspicuously depressed, abaxially conspicuously raised, base cordate, with 3–5 teeth on upper margin, apex acute or obtuse, oblique. Inflorescence paniculate, cymose or thyrsoid, many–flowered, bracteate and flat–topped, 8–10 cm long. Pedicels ca. 3 mm, pubescent. Bracts three, two linear, ca. 0.5 × 2 mm and another one elliptic–ovate, ca. 3 × 4 mm, abaxially softly brown pubescent. Calyx connation, funnel-shaped, ca. 4 mm, abaxially softly brown pubescent, 4-lobed; the calyx lobes unequal, two lobes broadly triangular, ca. 1.5 mm, two lobes narrow triangular, ca. 1 mm. Corolla rotate, valvate; petals 5, distinct white, spatulate clawed, apex retuse or crenately 2-lobed, glabrous. Stamens 15, filaments fused to ovary stipe to form an androgynophore, upper part widening to enclose ovary; anthers are also combined in a capitate cup enclosing the ovarium, bithecous. Androgynophore ca. 1.8 cm; anther head ca. 2 mm in diam., glabrous. Ovary 5-celled, 5-lobed; ovules 2 per locule, ascending, ovoid, ca. 1.5 mm, pubescent; style short, inconspicuous; stigma globose. Capsule yellowish puberulent, woody, loculicidally and septicidally dehiscent into 10 separate valves; obovoid-oblong, 2–3 cm, apex rounded. Seeds superposed, winged, wing developing abaxially, membranous, ca. 2 cm including wing, wing brown; endosperm reduced. Phenology:—Flowering in May and fruiting from July to November. Distribution and ecology:—The species is known only from Napo, northwestern Guangxi, China. And it grows in wet but sunny limestone valleys. Only one small populations with 23 individuals (including only 19 mature trees) have been found in Napo. All mature trees are more than 15 m in height and less than 3 m is observed for all immature trees. The rarity of this new species may be partially due to human activity because the habitat is also suitable for cultivating cassava, tobacco and other economic plants. And the seeds are often aborted. Comparing to the number of mature trees, the number of immature trees further indicates a decreasing population trend. In addition, all these trees are distributed in a total area of approximately 0.6 km 2. No population was found during repeated field surveys of the surrounding areas. According to the IUCN Categories and Criteria (IUCN 2022), the species is classified as Critically Endangered (CR: B1 + 2c). Therefore, it will be necessary to pay close attention to the conservation of this new species. Taxonomic relationships:—The comparison with the known species of Reevesia indicates that R. napoensis is similar to R. rotundifolia Chun (1934: 269, Fig. 6) and R. orbicularis in sharing the characters of the orbicular or ovate-orbicular leaf blade but it has larger phenotypic divergence with R. rotundifolia and R. orbicularis (Table 1). R. napoensis differs from R. orbicularis by the leaf blades upper margin with 3–5 teeth. R. napoensis is very similar to R. rotundifolia by the leaf blades upper margin with teeth, but there are very obvious differences. R. napoensis differs from R. orbicularis by cordate base, 7-veined base (vs. truncate or rounded 3-veined, bracts three (vs. one); calyx 4- lobed (vs. 3-lobed) and glabrous petals (vs. puberulent) (Figs. 5 & 7).Published as part of Feng, Hui Zhe, Qin, Yun Rui & Huang, Yun Feng, 2022, Taxonomic studies on the genus Reevesia (Malvaceae: Helicteroideae) II: on the identity of R. orbicularifolia and a new species from southwestern Guangxi, China, pp. 197-206 in Phytotaxa 545 (2) on pages 199-202, DOI: 10.11646/phytotaxa.545.2.8, http://zenodo.org/record/653474
A-Train observation of thermodynamic conditions above tropical cyclones
No full textThis dataset consists of A-Train observation of thermodynamic conditions above tropical cyclones. Satellite observations that pass over tropical cyclone events are identified in ‘A-Train_overpass_geolocation.nc’. Based on identified satellite overpasses, data samples from AIRS-L1B, DARDAR-Cloud, and MLS v4.2 products are collected. Above observed thick high-level clouds, a synergetic retrieval approach (joint AIRS-DARDAR retrieval, Feng et al. (2021 a, b)) is developed to obtain the thermodynamic profiles above the tropical cyclones.

Formation stabilization of underwater mobile sensing networks
No full textFormation control is essential for an underwater mobile sensing network (UMSN), an ad hoc network which wirelessly connects underwater vehicles of sensing and/or observing types via acoustic communications, to fulfill mobile sensing tasks. The problem of formation stabilization for an UMSN with varying communication topology is studied in this paper. Sufficient condition of formation stability is proposed in terms of stability analysis of linear time varying system and spectrum analysis of graph Laplacian of communication topology. Moreover, a design procedure for synthesis of formation controller is given
Evaluation of the effects of the communication cable on the dynamics of an underwater flight vehicle
No full textThis paper presents a numerical scheme to evaluate the effects of the communication cable attached to an underwater flight vehicle. Both simulation and model validation results show that the numerical scheme is effective and provides a means for developing a feed-forward controller to compensate for the cable effects when developing an autopilot for the tethered vehicle. Moreover, the numerical scheme can also be applied to predict the effects of the ROVs umbilical during its deployment. <br/
