Mapping Madness: HGIS and the Analysis of Irish Patient Records
AbstractThe Connaught District Lunatic Asylum (CDLA) opened at Ballinasloe, Co. Galway in 1833 as one of the first of a nationwide network of Irish District Asylums. Intended to serve the curable pauper lunatics of the counties of Mayo, Sligo, Leitrim, Galway, and Roscommon, the institution found itself at the heart of significant social, economic, and

Culture revisited: a geographic analysis of fertility decline in Prussia [PDF]
In this paper, we re-introduce geography into the analysis of fertility decline in the first demographic transition in Europe. We reanalyze Galloway et al.'s (1994) Prussian data, fitting structural models similar to those of Galloway et al.

Gaoya dianqi, 2013 对隔离开关操作引起的VFTO进行仿真是实现合理的绝缘配合及建设坚强特高压电网的重要课题。针对1 000 kV南阳开关站的HGIS布置,对隔离开关操作引起的VFTO进行了计算分析,计算结果表明,隔离开关中电阻对VFTO具有显著的抑制作用。南阳开关站隔离开关带有500Ω抑制电阻,在最苛刻条件下关合GIS中的VFTO幅值最大为1 266.6 kV,远低于其额定雷电冲击耐受水平2 400 kV;关合一次抑制电阻吸收的能量远低于其额定热容量,因此南阳开关站的隔离开关可以可靠操作。

Gaoya dianqi, 2017 为了掌握超高压变电站设备接地线入地电流的实际情况,为下一步做入地电流对地网金属材料的腐蚀研究提供数据依据,笔者选取了东北地区5个超高压变电站,从理论上分析了组合电器和敞开式设备接地线入地电流产生的原因,利用霍尔效应原理对变电站内设备接地引线上的电流情况进行了测试研究。研究表明,带金属外壳设备（如HGIS、GIS、罐式断路器等）接地线上的电流比瓷柱敞开式设备的要大得多,且为工频电流;电流的大小与多种因素有关,如土壤特性、负荷电流大小、变电站布置方式、接地线连接情况、外部干扰等;550 kV ...
