Specimens of the nominate subspecies were not available to the authors, but genitalia of the subspecies Jamides wananga roxina are described below. Genitalia of most bochus -group Jamides are very similar (Hirowatari 1992). Etymology. Named after the Wanang Conservation Area in Madang Province, PNG where the species was first collected in 2008. Ecology. The nominotypical subspecies is currently known to occur only in tall rainforest in the Wanang area of PNG. The species was flying with Jamides soemias purpurata. The life history is unknown. Comments. There is no significant variation in size (forewing length 13���15 mm), shape, colour and markings among the limited number of specimens. The distributional extent of the species is unknown., Published as part of Wilson, Peter R., Johnson, Ian R. & Lohman, David J., 2021, Jamides wananga, a new species from Papua New Guinea and Australia (Lepidoptera: Lycaenidae), pp. 107-122 in Zootaxa 4981 (1) on pages 112-114, DOI: 10.11646/zootaxa.4981.1.5, http://zenodo.org/record/5043237, {"references":["Hirowatari, T.

Male (Holotype) (Fig. 4A, B): Forewing length 13 mm; antenna black with white bands on the underside; thorax and abdomen upperside black and underside white. Forewing upperside: dark blue; black margin narrow ~ 1mm along termen widening to ~ 2mm at apex; dorsum straight. Hindwing upperside: dark blue becoming narrowly greyish blue towards the costa; termen margin very narrow (~ 0.2–0.3 mm) black edged with very narrow white on the inner margin particularly towards the tornus; a subtornal submarginal black spot with a series of submarginal black spots along the termen decreasing in size towards the apex at veins Rsand M 1; tornus and costa brown; tail black with white tip. Forewing underside: uniformly pale brown; termen margin very narrow (~ 0.2 mm) black edged with very narrow white on the inner margin between the veins; terminal and subterminal brown bands between each vein narrowly edged with white; a post median band edged with beige, curved and distinctly stepped at each vein; a short medial band at end of cell edged with beige. Hindwing underside: uniformly pale brown; termen with very narrow black margin (~ 0.2 mm) edged with very narrow white on the inner margin between the veins; small tornal black spot edged with white adjacent to two subtornal black spots edged with orange and a few iridescent blue scale; terminal and subterminal brown bands curved between each vein narrowly edged with white; a post median band edged with beige distinctly curved and stepped at each vein, a short medial band at end of cell edged with beige, and a submedial band edged with beige distinctly stepped at each vein.

Brachium curved and cylindrical with a blunt point. Socius on either side of the anus opening large, bulbous and semicircular in dorsal and ventral view, with numerous long hairs. Valva broad and spoon-like with a stout slightly curved dorsal projection above a semi-circular “toothed” indentation extending to a slightly curved very hairy posterior edge. Etymolog y. From a Torres Strait Islander song about Roxin (Dauan Island) sung in the traditional Kala Kawa Ya language. Ecology. Four specimens were collected over two days from 3:30 pm to 5:00 pm on 10–11 December 2017 and two specimens collected at 4 pm on 16 December 2020 on a dirt road through monsoonal vine scrub regrowth with a canopy to a height of approximately 5– 6 m. The area had been cleared previously and had remnants of abandoned banana and mango trees. The area is close to sea level and is subject to extended periods of waterlogging over the wet season. The life history is unknown. Comments. The limited number of available specimens do not vary significantly in size, shape, colour or markings. Jamides phaseli and J. amarauge have been collected at the same location and are the only other described Jamides species previously collected on the island. The specimens flew rapidly and erratically, which made capture extremely difficult. Adults were seen only in the late afternoon and have not been collected elsewhere on the island despite fairly extensive collection over an extended period of time by a number of collectors.

The International Technology Roadmap for Wide-Bandgap Power Semiconductors (ITRW) has four distinct technical working groups, each providing its own perspective on the technology and industrial drivers for the adoption of wide-bandgap (WBG) power semiconductors in power electronics. This article summarizes the progress toward an initial roadmap for the packaging and integration working group of the ITRW.

This paper presents a new simulator platform with findings from experiments aiming to identify the electrical characteristics of a marine vessel covered in photovoltaic modules, operating in various sea conditions. More specifically, we show that by giving a solar array the ability to reconfigure the arrangement of its modules in real time, that significant improvements (up to 50%) in power yield can be achieved compared to typical static arrays. A bespoke MATLAB simulator has been developed in order to model the complex interplay between the electrical arrangement of photovoltaic modules, the position of the photovoltaic modules on the vessel, the vessel’s tilting motion on the surface of the sea and the resultant irradiance based on the position of the Sun in the sky. Our approach allows the user to define these factors using a simple and intuitive graphical user interface so that a range of scenarios can be quickly simulated. We have used a basic test strategy that allows us to measure the effectiveness of different arrays and quantify performance in terms of mean output power and power stability over a range of sea conditions. A key factor in the effectiveness of the use of marine survey vessels is their ability to remain at sea for extended periods, preferably avoiding the use of high-carbon fuel sources such as diesel generators. This is of particular importance when observing marine life as the platform needs to operate as quietly as possible. The ASV Global C-Enduro autonomous, self-righting platform is the initial application for this new energy harvesting system, with the aim to extend mission endurance. A second case study has also been performed in parallel with this, using a much more divergent orientation of onboard photovoltaic modules in order to asses the ability for a dynamic photovoltaic array to increase and stabilise power output.

This paper describes a design approach for incorporating sequence-aware watermarks in soft IP embedded processors. The influence of watermark sequence parameters on detection, area and power overheads is examined, and consequently a sequence-aware method for incorporating sequence-aware watermarks in soft IP Embedded Processors is proposed. The intrinsic parameters of sequences, such as the activity factor and the overlapping factor are introduced, and their impact on correlation results is demonstrated. Measurement experimental results from FPGA and ASIC validate the design approach and demonstrate the resulting IP protection and subsequent costs for constrained embedded processors. Results presented in this paper show that the tradeoff occurs between the watermark robustness against third party IP attacks and hardware implementation costs. The analysis of this tradeoff is provided and an applicationspecific watermark implementation is proposed.
