Power Optimization and Real-time Management of Grid-connected Microgrid with Nonlinear Battery Degradation Model in Energy Market
No full textThis paper presents a method for optimal power management of grid-connected microgrids. Dynamic programming (DP) algorithm is utilized to forecast the global optimal solution to microgrid power flow dispatch, considering day-ahead forecasts of PV power and loads. The impact of various retail electricity pricings, which include fixed-price, time-of-use (TOU) pricing and real-time pricing (RTP) based on locational marginal pricing (LMP), are discussed. Battery storage with its nonlinear charging/discharging cost model is also exploited for system power optimization. The objective is to achieve the minimum microgrid system operation cost, in other words, the maximum economic benefits for end-users. Rule-based (RB) algorithm is also studied as a baseline for comparison to the DP solution. Typical cases under different weather scenarios have been studied, simulated and compared

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
Association between Attention Function and Clinical Symptoms for Children with Attention Deficit/Hyperactivity Disorder
No full text目的：本研究之目的為探討6-8歲注意力不足過動症（ADHD）兒童在持續注意、工作記憶及抑制控制等認知能力發展與臨床注意力不足過動症狀的相關性。
方法：收集台北市某地區醫院15位ADHD兒童及大台北地區12位正常兒童分別接受電腦化注意力測驗TAP中警醒度、聽覺持續注意、視覺持續注意、工作記憶、抑制控制go/no-go等分項測驗。兒童的父母接受結構式診斷性會談（K-SADS-E）以提供兒童相關資訊並填寫柯能氏父母版量表。老師填寫柯能氏教師版量表。
結果：兩組兒童在抑制控制go/no-go測驗中假警報次數及聽覺持續注意中遺漏的次數有明顯差異，在其他項目的注意力測驗則無明顯差異。K-SADS-E ADHD症狀數與抑制控制go/no-go中假警報次數有顯著相關，對照組的魏氏兒童智力測驗綜合智商較ADHD組高，有顯著差異。以回歸分析調整綜合智商的影響後，ADHD組兒童仍比正常組兒童在抑制控制go/no-go有顯著較高的假警報次數，ADHD症狀數與抑制控制go/no-go中假警報次數仍有顯著相關。
結論：本研究為橫斷式分析，由結果顯示ADHD兒童在抑制控制的表現較正常組兒童差，而抑制控制能力與臨床症狀似有相關聯。為了更清楚了解症狀改變是否與抑制控制能力發展有關，未來得考慮以前瞻式追蹤研究設計，長期觀察ADHD症狀改變與抑制控制能力發展的關連性。Objective: This study aimed to evaluate the association between the development of attention and behavioral symptoms of children with attention deficit/hyperactivity disorder (ADHD). Methods: Samples included 15 children, aged 6 to 8 years old, who sought help at Child and Adolescent Psychiatric Clinic in Taipei Municipal hospital and were diagnosed with ADHD, and 12 children without ADHD and other psychiatric disorders from Taipei area. All subjects were tested by computerized program of attention tests including alertness, auditory sustained attention, visual sustained attention, inhibitory control go/no-go test and working memory. Their parents received a psychiatric interview to report on these children using the Chinese version of the Kiddi Schedule of Affective Disorders and Schizophrenia-Epidemiologic version (K-SADS-E) and completed the Chinese version of the Conners’ Parent Rating Scale-Revised: Short Form. Their teachers completed the Chinese version of the Conners’ teacher Rating Scale-Revised: Short Form. Result: The ADHD and normal group children differed significantly in the false alarm of go/no-go test and the omission of auditory sustained attention. The number of ADHD symptoms measured by the K-SADS-E was correlated significantly with the false alarm of go/no-go test。The normal group children had higher IQ. When IQ was adjusted, group difference in the false alarm of go/no-go test and the significant correlation between ADHD symptoms and the false alarm of go/no-go test still persisted. Conclusion: The major findings of this study are that ADHD children had higher false alarm rate in inhibitory control and the false alarm rate is associated with ADHD symptoms. To further confirm whether the improvement of clinical symptoms is correlated with the development of inhibitory control, a prospective follow up study should be carried out.誌謝 ---------------------------------------------------------------------- Ⅱ

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
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
