开关DC-DC变换器斜坡补偿的稳定性控制研究

从混沌稳定性控制的角度研究了采用斜坡补偿的buck、boost和buck-boost开关DC-DC变换器的稳定性控制机理,建立了采用补偿斜坡的开关变换器的离散映射迭代模型,得到了开关变换器电路的稳定性判据和补偿斜坡斜率的表达式。利用分叉图、Lyapunov指数谱和时域波形图,清晰地描绘出补偿斜坡电流(或电压)对开关变换器的电路稳定性能的影响。研究结果表明,采用斜坡补偿技术能有效地改善开关DC-DC变换器的稳定性。     

低功耗无损电流检测技术的分析与设计

通过分析DC-DC电流模开关电源的结构,提出了一种新颖的低功耗无损电流检测技术,降低了开关电源的静态功耗。该技术实现了虚拟的无损电流检测电阻和一个低功耗高灵敏度的电流检测放大器。通过降低电流检测电路的功耗,优化了电流模开关电源控制环路的功耗,从而实现了静态功耗的最小化。基于无损电流检测技术设计,开关电源的静态功耗为61.22mW,为典型情况的57.5%。     

文本类型学、目的论与商标翻译中的功能转换

德国的功能主义翻译理论摆脱了传统对等理论的束缚,以文本功能为基础,以目的法则为主导,主张翻译标准多元化,拓宽了翻译研究的视野,为翻译活动的诠释提供了新的视角。本文结合功能派翻译理论的两大支柱理论——文本类型学和目的论,探讨商标名称的文本功能及翻译策略的选择。     

Social Entrepreneurship in Communities

The United States ranks low on many measures of population health. In addressing this societal problem, nonprofit health conversion foundations are emerging as important, local social entrepreneurs. We investigated the processes by which these organizations create and implement locally situated innovative approaches to promote health and wellness. Using an inductive, qualitative approach, we identified central themes by which conversion foundations, as social entrepreneurs, developed collaborative solutions to health. We found that they defined the social problem, generated social capital in the community, and educated potential partners. These mechanisms helped build a groundwork for collaboration among community actors. Conversion foundations then convened partners with complementary competencies to develop creative solutions. This research contributes to the literature on social entrepreneurship and nonprofits by expanding understanding of how foundations can foster community collaborations to develop innovative solutions to social problems. Further, this study sheds light on the activities and processes of nonprofit health conversion foundations as actors with the potential to improve population health.     

Advocating for an End to Reparative Therapy: Methodological Grounding and Blueprint for Change

Despite the ethical and methodological concerns surrounding reparative therapy (RT) (also known as conversion therapy), a 2011 journal published a study claiming that lesbian, gay, and bisexual persons can “change” their sexual orientation. While much has been written about the deleterious effects of RT it continues to be researched and practiced, and, therefore, continues to cause harm. This article reviews methodological and ethical problems of RT and factors associated with it, and suggests steps to decrease and eventually end its practice as an aspect of social work's mission, which is to protect vulnerable populations, including lesbians and gay men.
