De Fast-Fourier Transform: Het gebruik van de routine van R.C. Singleton
No full textDoel van dit rapport is de lezer inzicht te verschaffen in het gebruik van de FFT-routine van R.C. Singleton zoals die in het rekencentrum van de T.H. - Delft in gebruik is. Voor een beschrijving van de werking van deze routine wordt verwezen naar het in de literatuurlijst vermelde artikel van Singleton (Lit. 1). Met nadruk wordt erop gewezen dat er meerdere FFT-routines in omloop zijn die alle anders werken en daarom in gebruik kunnen verschillen. Het onderhavige rapport beschrijft uitsluitend het gebruik van de routine van Singleton. Als laatste punt in deze inleiding wordt speciaal het boek van Brigham genoemd (Lit. 2) waarin zeer veel informatie te vinden is over het gebruik van de FFT-methodeHydraulic EngineeringCivil Engineering and Geoscience
Difference in the D-dimer rise between women with singleton and multifetal pregnancies
No full textIntroduction: The differences in the D-dimer rise between women with singleton and multifetal pregnancies have not been studied extensively. Materials and Methods: D-Dimer levels were determined in 1089 blood specimens from 1089 women in various stages of pregnancy, including 977 and 112 women with singleton and multifetal pregnancies, respectively. None of the 1089 women developed hypertension or clinical venous thromboembolism during pregnancy or in the postpartum period. Results: The D-dimer levels were significantly and positively correlated with gestational week at examination in women with singleton or multifetal pregnancies. The D-dimer levels (mu g/ml, mean +/- SD [number of specimens]) determined at the 1st trimester did not differ significantly (0.81 +/- 0.82 [102] for singleton vs. 1.20 +/- 0.77 [7] for multifetal), but those at the 2nd (1.61 +/- 1.45 [216] vs. 2.62 +/- 2.26 [59]) and 3rd (2.37 +/- 2.22 [659] vs. 4.02 +/- 2.14 [46]) trimesters were significantly higher in women with multifetal than singleton pregnancies. The 90th percentile value was 4.31 mu g/ml for 1089 specimens. A significantly greater number of women exceeded 4.31 mu g/ml during the 2nd (16.9% vs. 5.6%, P = 0.0043) and 3rd (34.8% vs. 10.6%, P < 0.0001) trimesters among those with multifetal than with singleton pregnancies. Conclusions: The degree of D-dimer rise in pregnancy was greater in women with multifetal than with singleton pregnancies. (C) 2013 Elsevier Ltd. All rights reserved
Coagulation-fibrinolysis is more enhanced in twin than in singleton pregnancies
No full textAims: To examine whether coagulation-fibrinolysis in late pregnancy in women with twin pregnancies is more pronounced than in women with singleton pregnancies.
Patients and methods: The plasma levels of D-dimer, fibrinogen/fibrin degradation products (FDP), and fibrinogen, the platelet count, and the antithrombin activity were assessed from 3 weeks before delivery until postpartum day 7 in 48 women (24 singleton and 24 twin pregnancies) without preeclampsia who underwent cesarean sections.
Results: Women with singleton or twin pregnancies gave birth at 37.3±1.2 weeks or 35.2±1.4 weeks, respectively. Compared with singleton mothers, prenatal D-dimer and FDP levels were consistently and significantly higher among women with twin pregnancies. A significantly larger proportion of twin mothers exhibited prenatal levels of D-dimer >5.0 μg/mL, FDP >10.0 μg/mL, fibrinogen <420 mg/mL and antithrombin activity <70%. In addition, prenatal antithrombin activity in plasma was significantly lower.
Conclusions: Coagulation-fibrinolysis is more enhanced in women with twin gestation than in women with singleton gestation
Reply to "Comment on 'Inflation with a graceful exit and entrance driven by Hawking radiation' "
No full textThe Comment [J. T. Firouzjaee, preceding Comment, Phys. Rev. D 89, 068301 (2014)] raises two points in regard to our paper [S. K. Modak and D. Singleton, Phys. Rev. D 86, 123515 (2012)]. The first is that one cannot use the tunneling picture to obtain the temperature and particle production rate in the Friedman-Robertson-Walker space-time. The second comment raised by Firouzjaee is that the Hawking-like radiation model for inflation presented in [Modak and Singleton; S. K. Modak and D. Singleton, Int. J. Mod. Phys. D 21, 1242020 (2012)] is inconsistent with the observed scalar and tensor perturbation spectrum. We show that the first comment is beside the point-we do not use the tunneling method in our papers [Modak and Singleton; Modak and Singleton]. The second criticism by Firouzjaee comes from the author evaluating quantities at different times-he evaluates the parameters of our model at the beginning of inflation and then compares this with the scalar and tensor perturbations evaluated at the horizon exit point.From Physical Review D, Vol.89(6), 68302, available online: http://dx.doi.org/10.1103/PhysRevD.89.068302.

Harry H. Singleton.II, a warrior as activist: racism in Horry county, South Carolina , 1965-2005, 2009
No full textThis historical narrative examined the impact of institutional and individual racism during the Post Civil Rights Era by analyzing the life and work of minister, businessman, and educator, Reverend Harry H. Singleton, II of Horry County. South Carolina. Special attention was given to Singletons role in the integration of Horry County Public Schools. the Conway High School football boycott, and his work as a civil rights leader with the National Association for the Advancement of Colored People (NAACP). Further, incidents in Singletons life and career as a civil rights activist reflect the legal support of district courts in South Carolina. particularly in the case of Harry H. Singleton v. Horry County Board of Education. Based on the research, Singletons life is reflective of an African-American leader whose contributions to race relations on the grassroots level was indicative of his life experiences growing up in Edgefield. South Carolina and his commitment to correcting racism in Horry County, South Carolina from 1965 to 2005
Constructing Cooperation
No full textIn a pathbreaking analysis, Sara Singleton explores the development of schemes for the management of fisheries in the northwestern United States in which native American tribes, and state, federal, and local governments cooperate to manage limited fishing resources. In the policy dispute over the apportionment of scarce resources, some argue that only government control or private ownership will prevent the destruction of limited common resources. The author shows how cooperation among interested parties can produce a workable system for self-management of common resources. Through the detailed study of the management of fisheries in the Northwest the author tests theories explaining the basis of collective action and social cooperation, an area of rich theoretical speculation in political science, law, economics and sociology. At the same time, her findings have important implications for policy makers who are interested in efficient and effective schemes of resource control that avoid the problems caused by regulation by remote government officials or private control. This book will appeal to policy makers concerned with the management of natural resources as well as to economists, political scientists, and sociologists concerned with collective action problems.

ASSESSING VOLUNTEER MOTIVATION AND SATISFACTION: A COLLABORATION BETWEEN SINGLETON MOMS AND THE COMMUNITY ACTION RESEARCH EXPERIENCES (CARE) PROGRAM
No full textabstract: The Community Action Research Experiences (CARE) program collaborated with Singleton Moms, a local non-profit organization that provides financial, psychological, and social support services to single parents with cancer. The purpose of this action research project was to assess the volunteer program at Singleton Moms. Both past and present Singleton Moms' volunteers (N = 123; 87.0% female) completed an online survey assessing their motivation for volunteering and their satisfaction with the organization. A mixed ANOVA was conducted to identify the most important motivation and satisfaction domains and to see if the findings depended on whether the volunteers were current or past volunteers. For the motivation assessment, results indicated that the volunteers rate the cancer specific and moral/human kindness domains as the strongest reasons for motivating them to volunteer at Singleton Moms. In addition, results revealed that the social connection motivation domain was the only domain with differences between the ratings of the past and present volunteers. For the satisfaction assessment, results indicated that the volunteers rate the organizational climate domain as the most fulfilled area of satisfaction within the Singleton Moms' volunteer program. It was also revealed that there were no significant differences between the ratings of the past and present volunteers among all satisfaction domains. Both the quantitative and qualitative findings suggest that Singleton Moms' implications for action may include: 1) a volunteer database audit, 2) streamlining communications, 3) variability in volunteer times, and 4) bolstering volunteer motivation. Implementing some of these actions may help Singleton Moms increase volunteer motivation and satisfaction and thus create a more effective volunteer program. Ultimately, this may encourage volunteers to continue their services at Singleton Moms and thus help Singleton Moms expand their support programs and assist additional families
Implementing design patterns as parametric aspects using ParaAJ: The case of the singleton, observer, and decorator design patterns
No full textAbstractImplementation of a design pattern can take many forms according to the programming language being used. Most of the literature presents design patterns in their conventional object-oriented implementations. Several other studies show the implementation in aspect-oriented languages such as AspectJ, EOS, and Caesar. In this work, we compare the implementation of three design patterns: singleton, observer, and decorator design patterns in these languages and also discuss the possibility of implementing them in ParaAJ: an extension to the AspectJ language that implements the idea of parametric aspects. We found that ParaAJ helps in making the implementation of the singleton and observer patterns reusable but it fails to help in the decorator case. The problem with the decorator pattern exists because of the current translation mechanism of ParaAJ׳s aspects to normal AspectJ׳s aspects. This opens the door for further work in ParaAJ to better support the idea of parametric aspects
