A Survey informed modelling of temporal diffusion of PV-based communal grids in a rural developing community.
No full textAn agent-based model (ABM) is developed in Netlogo as a tool for evaluating temporal diffusion of PV-based communal grids in a rural developing community. ABMs model individual entities within a complex system and the rules that govern the interactions of the entities within the system, to capture the overall effect of such interactions. Results show that given various choices, small PV mircogeneration systems would emerge as the prefered source of electrification for many households. Also, with increasing power demands, many household would prefer communal grids to the national utility grid. Furthermore, introduction of favourable government policies in the form of subsidies and mircocredit facilities, coupled with increasing social acceptance, would lead to increased PV installations and correspondingly to increased communal grid connections. Specifically, introduction of a subsidy of $0.15/kWh would result in an increase of 249% in communal grid connections. Increasing the sensing radius from 1 km to 2 km would result in an increase of 118% in communal grid connections
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Resilient minigrids using PV and biofuels
No full textWe are developing software tools to help design minigrids optimised for developing countries. In particular, the minigrids must be resilient to weather and climate, provide predicable generation, with a long maintenance-free lifetime. Solar PV and biofuels are the primary energy sources, although this will depend on the local resource. Batteries will not have a major role because of their limited lifetime, expense, and susceptibility to theft. Instead, biofuels are used to store energy chemically and provide dispatchable generation.
We will present an overview of the project, details of existing and planned solar irradiance monitoring at partner universities in Africa (Uganda, Congo-Brazzaville, and Tanzania), and initial irradiance datasets. Low-frequency high-accuracy data will be recorded and used to quantify errors in wide-area indirect datasets, such as data available through PV-GIS. There are very limited ground-based pyranometer measurements in East Africa, with no operational BSRN stations. High-frequency low-accuracy data will be recorded and later used as an input dataset for simulations and lab-based operational minigrids. The logging frequency is sufficiently high to capture cloud-edge events occurring on sub-second timescales. Spikes in irradiance and high ramp rates can cause grid instability and potentially damage inverters and other power components.
An existing monitoring station at CREEC, Kampala, Uganda, has been recording irradiance for 6 months. The station includes an LP02 Pyranometer (ISO-second-class) and a triplet of silicon sensors spaced at 5 m. Data is recorded at 10 Hz, allowing irradiance ramp rates and cloud-edge reflections to be captured by the silicon sensors. Using cross-correlation, cloud speed and direction are calculated from the time shifts of cloud edges detected from sensor pairs. Cloud speed and direction govern the dynamic nature of irradiance, and hence the electrical output of PV modules and arrays
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
