Optimal task allocation in hypercube multiprocessor ensembles

Criteria are established to determine the optimal policy for allocating a set of uniform tasks onto a multiprocessor hypercube ensemble. It is shown that the optimal policy depends on the ratio of computation to intertask communication required by the distributed program, and that based on this ratio, tasks should be placed either all on one processor or uniformly distributed over the largest possible hypercube.     

The Relevance of Early Lacan for Psychoanalytic Phenomenology and Contextualism: Preliminary Communication.

In this article, the author attempts to show that Lacan's early writings are relevant to the author's own psychoanalytic perspective by virtue of Lacan's view of the psychoanalytic method and process as phenomenological, hermeneutic, and dialogic.

Delay-insensitive codes — an overview

The problem of delay-insensitive data communication is described. The notion of delay-insensitive code is defined, giving precise conditions under which delay-insensitive data communication is feasible. Examples of these codes are presented and analyzed. It appears that delay-insensitive codes are equivalent with antichains in partially ordered sets and with all unidirectional error-detecting codes. Tom Verhoeff received the B.S. and M.S. degrees in mathematics from Eindhoven University of Technology, The Netherlands, in 1985. He is currently an Assistant Professor at the Department of Mathematics and Computing Science of the same university. His main research interests are parallel computations, especially formalisms for their specification and design, and their implementation as delay-insensitive VLSI circuits.     

Maternal Power Assertion in Discipline and Moral Discourse Contexts: Commonalities, Differences, and Implications for Children's Moral Conduct and Cognition.

Parental power assertion is traditionally studied in the behavioral domain--discipline triggered by the child's immediate misbehavior--but rarely in the cognitive domain--parent-child discussions of the child's past misbehavior. Maternal power assertion was observed in "do" and "don't" discipline contexts from 14 to 45 months and in the context of mother-child discourse about a recent misbehavior at 56 months. Mothers' use of power cohered across the "do," "don't," and discourse contexts, but its implications were domain specific. Power assertion in the "don't" discipline context predicted behavioral outcomes (more moral conduct at 56 and 73 months, less antisocial conduct at 73 months) but not cognitive outcomes (moral cognition at 56 and 73 months). Power assertion in the discourse context predicted less mature moral cognition but not moral or antisocial conduct. Mothers' high Neuroticism predicted more power assertion in all three contexts. Child effects were examined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

GSM技术在配电网故障自动隔离及恢复系统的应用

为了使配电网故障的隔离和恢复的通讯更加可靠、迅速、经济，设计了一种基于GSM通讯技术，借助移动通讯系统短信业务和数据业务，实现配电网故障的自动隔离与恢复的系统。该系统通过MCU采集数据，判断故障位置与故障类型，经GSM通讯模块上传主站，主站统筹全局，实现故障段的切除，非故障区的供电。阐述了系统的工作原理、硬件结构、通讯协议和软件流程。现场的实际运行情况证明数据上报通讯准确率为100％，多次模拟线路故障，根据故障点的不同，一般在2～3min内系统都能可靠的隔离故障，恢复系统。     

Measurement accuracy enhancements for wideband modulated signals

Time‐domain waveform measurements of wideband modulated signals, although attractive for communication systems modeling applications, have until now lacked the required accuracy for quantitative analysis. New developments described here enhance the accuracy of these measurements, enabling their application to communication system characterization and modeling. © 2003 Wiley Periodicals, Inc.
