Relationship between GSR and anxiety indexes in projective drawings.

96 male college students drew a man, a woman, and an automobile while continuous GSRs were obtained. A significant difference was found in the degree of anxiety for the 3 drawings. The auto yielded the lowest level of anxiety, and the woman drawing the highest level of anxiety. Adaptation differences were found for 7 of the graphic anxiety indexes. For the man drawing, secondary sexual body parts yielded the most anxiety, followed by the sexual body area. The sequence was the opposite for the woman drawing. Low but significant correlations were found between 10 of the 23 possible graphic indexes and either GSR frequency or conductance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

无线节点GSR质量控制与现场处理技术

无线节点采集系统相对有线采集系统具有不受带道能力限制、可独立采集、自动存储、体积小、施工方便、观测系统设计灵活、降低安全风险、提高生产效率、降低作业成本等优势,从理论上讲更易于实现"两宽一高"的高效采集作业。近几年来,无线节点采集技术被各油公司的认可程度正在逐步提高,并已有多个成功运作的案例,是当前地震采集的一个重要发展方向。本文以GeoSpace公司研发的自主独立存储节点采集系统GSR为例,阐述了节点数据采集系统的工作原理、质控方法与现场处理技术。     

GSR reactivity as a function of anxiety, instructions, and sex.

"GSR conditioning and extinction measures were obtained on 120 college Ss in a factorial experimental design in which 12 treatment groups were divided into 2 sex groups, 3 instruction groups, and high- and low-anxiety groups. The 3 instruction groups were given 3 different kinds of instruction designed to be: (a) apprehension arousing; (b) neutral; and (c) reassuring." Male Ss showed less conditioning when given reassuring instructions; female Ss showed the least conditioning with the apprehension-arousing instructions. Females showed greater GSR reactivity than males in all phases of the experiment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A new real time disk-scheduling method based on GSR algorithm

Disk scheduling has an important role in QOS guarantee of soft real-time environments such as video-on-demand and multimedia servers. Since now, some disk-scheduling algorithms have been proposed to schedule real-time disk requests. One of the most recent algorithms is global seek-optimizing real-time (GSR) that schedules the disk requests with different ready times by a global regrouping scheme. In the present paper, we propose a real-time disk-scheduling algorithm based on GSR that is called IGSR (improved GSR). IGSR creates the scan-groups of the requests and tries to find a good feasible schedule by optimized grouping with considering another chance for tasks that miss their deadlines at initial grouping. With regard to the admission policy of tasks, two different version of proposed method are presented: the first one has been designed for the case that all the disk requests available simultaneously and second one has been designed for the case that requests are admitted dynamically (GSR does not support the second one). It means that in the second case, the request queue may change when a task is running but in the first one it does not change. Simulation results showed IGSR outperformed GSR and some other related works in terms of maximum supportable streams, number of missed deadlines, and disk throughput.     

街道步行环境夜间安全感关键影响因素 识别——基于可穿戴生理传感器的感知实验

找出影响街道步行环境夜间安全感的关键因素是提 升街道夜间活力的重要前提，确定采用基于生理传感器的现场 感知实验方法对关键影响因素进行识别。首先结合相关理论与 街道环境整体特征，建立环境自变量；再以可穿戴传感器收集 的皮肤电反应(GSR)为安全感测度基础，通过“唤醒-效价” 模型得出被试安全感因变量；而后建立夜间安全感的可视化地 图，从地图中选取产生不同安全感的环境样本，并以最优子集 回归的方法建立识别模型。基于45名被试的现场感知实验结 果表明，对夜间安全感产生影响的环境因素可以分为关键影 响、非关键影响与无影响因素。而本次实验得到的关键影响因 素为建筑内透光、绿视率和街道界面透明度，证明了夜间街道 中“自然监视”策略的重要性，同时给出基于提升“自然监 视”的街道夜景设计策略     

模拟退火免疫粒子群算法在皮肤电信号情感识别中的应用

为了增强情感识别过程中皮肤电反应(GSR)信号特征选择的有效性,提出了一种改进的模拟退火免疫粒子群算法。首先,对342组被试6种情感的GSR信号进行去噪处理和原始特征提取;然后,将模拟退火机制引入到免疫粒子群(IPSO)算法的粒子更新过程中,使用新构造的模拟退火免疫粒子群(SA-IPSO)算法进行特征优化选择。实验表明:与IPSO相比,SA-IPSO能以较少特征获得较高的识别率,模拟退火机制的应用能更好地优化特征选择过程,且新的算法具有良好的全局收敛性能。     

GSR conditioning and personality factors in alcoholics and normals.

Alcoholic and nonalcoholic introversive and extroversive Ss were placed in a GSR conditioning situation. Significant differences in conditionability were not found between alcoholics and the nonalcoholic group with regard to the intro-extroversion dimension. The results were seen as confirming aspects of Eysenck's (1957) theory of personality. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
