Introduction
No full textThe current desire to go and explore space is as strong as ever. Past space powers have been gradually joined by a flurry of new nations eager to test and demonstrate their technologies and contribute to an increasing body of knowledge. Space robotics and autonomous systems (RAS) are important to human's overall ability to explore or operate in space, by providing greater access beyond human spaceflight limitations in the harsh environment of space and operational handling that extends astronauts' capabilities. RAS can help reduce the cognitive load on humans given the abundance of information that has to be reasoned upon in a timely fashion and hence are critical for improving human and systems' safety. RAS can also enable the deployment and operation of multiple assets without the same order of magnitude increase in ground support. Given the potential reduction to the cost and risk of spaceflight both manned and robotic, space RAS are deemed relevant across all mission phases such as development, flight system production, launch, and operation. This chapter introduces the book by providing the basis of space RAS, such as key technological challenges, relevant applications over the horizon as well as the recent advances to be presented in the remainder of the book

Achieving full diversity in multi-antenna two-way relay networks via symbol-based physical-layer network coding
Full text linkThis paper considers physical-layer network coding (PNC) with M-ary phase-shift keying (MPSK) modulation in two-way relay channel (TWRC). A low complexity detection technique, termed symbol-based PNC (SPNC), is proposed for the relay. In particular, attributing to the outer product operation imposed on the superposed MPSK signals at the relay, SPNC obtains the network-coded symbol (NCS) straightforwardly without having to detect individual symbols separately. Unlike the optimal multi-user detector (MUD) which searches over the combinations of all users’ modulation constellations, SPNC searches over only one modulation constellation, thus simplifies the NCS detection. Despite the reduced complexity, SPNC achieves full diversity in multi-antenna relay as the optimal MUD does. Specifically, antenna selection based SPNC (AS-SPNC) scheme and signal combining based SPNC (SC-SPNC) scheme are proposed. Our analysis of these two schemes not only confirms their full diversity performance, but also implies when SPNC is applied in multi-antenna relay, TWRC can be viewed as an effective single-input multiple-output (SIMO) system, in which AS-PNC and SC-PNC are equivalent to the general AS scheme and the maximal-ratio combining (MRC) scheme. Moreover, an asymptotic analysis of symbol error rate (SER) is provided for SC-PNC considering the case that the number of relay antennas is sufficiently large

Compound eyes pale brown, ocelli yellow with black inner margin. Antenna black. Mouthparts yellow; maxillary palpus and labial palpus with apices black, mandible with apical half reddish brown. Prothorax yellow; meso and metanota pale brown with lateral margins black. Legs brown, with short, dense, yellowish brown setae; tarsi brown but sometimes darker; tarsal claws reddish brown. Wings grayish brown with large hyaline marks; pterostigma short, pale yellow. Forewing with two or three small spots on basal intercostal area and with entire apical half of intercostal area grayish brown; basal third of wing with spots and diffuse hyaline band; median transverse hyaline band distinct and extending from C to M; apical margin with several small subhyaline spots along longitudinal veins. Hindwing similarly marked; basal half mostly hyaline; median transverse hyaline band subquadrate, much larger than that of forewing. Veins brown. Rs 5 branched, R 2 apically 3 branched, R 3 and R 4 curved backward at tip; 3 crossveins between R 1 and Rs; M 2 branched; 1 A 2 branched. Abdomen dark.

This species appears closely related to N. koreanus Weele in having the similar dark wings with large hyaline marks, but can be easily distinguished by the orange head, narrowed apical hyaline marks of the forewings, and the digitiform female tenth tergum. In N. koreanus, the head is brownish, the apical hyaline marks are much wider, and the female tenth tergum is thickened with a produced apical corner (Weele, 1910; Kimmins, 1954).Published as part of Liu, Xingyue & Yang, Ding, 2005, Notes on the genus Neochauliodes from Guangxi, China (Megaloptera: Corydalidae), pp. 1-24 in Zootaxa 1045 on pages 14-15, DOI: 10.5281/zenodo.16988
