Vehicle Based Intersection Management with Intelligent Agents
No full textSignal-based intersection management will change when vehicles with intelligent capability are available in the future. Intelligent agents embedded in vehicle software will be responsible for vehicle control and route guidance. Intersection management can be achieved through the collaboration of these agents, without a centralized control infrastructure. This research focuses on the use of distributed multi-agent systems to provide microscopic adaptive control which might reduce traffic delay and chances of collisions at intersections. A hypothesized Mobile Ad-hoc Network provides communication links to connect the agents.Intelligent Agents, Adaptive Intersection Control
Financing and Deploying Automated Freight Systems
No full textNew technologies are bringing Automated Freight Systems (AFS), which aim to reduce congestion, mitigate environmental impacts and enhance public safety, to fruition. The financing and deployment issues of AFS differ from other Intelligent Transport System applications. This chapter briefly introduces major concepts of AFS. The financing strategies for these concepts are discussed, in which the government subsidies play an important role through the use of public-private partnership. Economies of scale and externalities of the current and new systems are discussed. In the discussion of the deployment of AFS, it is suggested that deployment schemes are highly correlated with financing strategies.Automated Freight, Pipeline, Trucks, Rail

Fiscal Decentralization, the Composition of Public Spending, and Regional Growth in India
No full textIn this paper, we present an analytical model for examining the growth impact of intergovernmental and intersectoral allocation of public expenditure. The model helps us quantify the role of fiscal decentralization in regional economic growth and identify whether central and local allocation of public spending among various sectors are growth-enhancing. Applying our analytical framework to a panel data set of 16 major states in India, we have found that, in many cases of our regressions, fiscal decentralization is positively, and even statistically significantly, associated with state economic growth. The state allocation of public spending in various sectors is broadly consistent with "growth-maximizing", whereas increases in the central allocation of its budget among development projects, nondevelopment projects, and social and community services by cutting the center¡¯s spending on all other functions can promote regional growth. Furthermore, the distortionary effect of the state tax in India is dominated by the productive effect of tax-financed public spending, whereas the reverse holds for the central tax.
Traveling Waves for the Diffusive Nicholson's Blowflies Equation
No full textWe consider traveling wave front solutions for the diffusive Nicholson's blowflies equation on the real line. The existence of such solutions is proved using the technique developed by Wu and Zou [7]. Some numerical simulation using the iteration formula of Wu and Zou [7] is also provided
Goniocotes Gustafsson, Grossi, Ren & Zou, 2023, s. lat
No full textGoniocotes s. lat With the removal of G. parviceps and G. mayuri to Pavoniocotes, the morphological circumscription of Goniocotes has been somewhat simplified. Goniocotes can now be largely circumscribed as the small-bodied goniodid species that have sexually monomorphic antennae, simplified solenoid male genitalia, and vulval margins with 2–4 (typically 3) thorn-like setae. However, some species have more complicated male genitalia (eg Goniocotes rolandi Gustafsson et al., 2021a), and species from Afropavo congensis Chapin, 1936 are morphologically aberrant within the genus (Clay 1938). Further revisions of the genus, including redescriptions of more species, are necessary to establish the characters that can be used to circumscribe the genus, as well as the limits of the genus. Several groups of lice synonymised with Goniodes by Price et al. (2003) are likely more closely related to Goniocotes, based on the morphology of their genitalia. This includes at least the proposed genera Homocerus Kéler, 1940, Maleoicus Mey, 1997, and Weelahia Mey, 1997, but probably also others (see Mey 1997 for illustrations). In these genera the antennae are also sexually monomorphic, and the placement of these species in Goniodes thus makes the morphological circumscription of that genus more difficult. A large number of poorly known species of Goniodes that have sexually monomorphic antennae, or antennae that are not dimorphic in the same way as the Goniodes treated here, may also be closer to Goniocotes; this includes, for example, Goniodes astrocephalus (Burmeister, 1838) and Goniodes coronatus (Giebel, 1874). However, as we have examined no specimens of any species in these genera, we presently do not propose any further changes to the classification of these species, pending a more thorough revision of the group.Published as part of Gustafsson, Daniel R., Grossi, Alexandra A., Ren, Mengjiao & Zou, Fasheng, 2023, The Goniodidae (Phthiraptera: Ischnocera) of peafowl (Aves: Galliformes: Pavo), with description of a new genus, pp. 996-1048 in Journal of Natural History 57 (17 - 20) on page 1041, DOI: 10.1080/00222933.2023.2226375, http://zenodo.org/record/827079
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
