基于ARM实现的数据通信转换的研究

在现代炮兵作战系统中,观察所通过TCP/IP网络实现数据通信,而阵地炮终端通过串口数据通信。基于上述局限,提出用嵌入式开发炮兵信息化作战平台,通过32bitARM处理器实现了各观察所TCP/IP网络接口与各阵地的串口接口不同协议数据通信路由选择的转换。     

基于Windows CE的串行通信

Windows CE是面向移动计算和嵌入式应用的嵌入式操作系统,特别为有限的硬件资源设计了多线程、多任务和具有优先级的操作系统环境,且具有强大通信能力,RS 232串行通信是Windows CE支持的最基本的通信方式。本文主要致力于Windows CE下的串行通信,详细介绍了在Windows CE下实现RS 232串口通信的方法和过程,包括如何打开、配置、读写、关闭串口和使用多线程来实现类似的异步串口通信,深入讨论了正确实现通信的几个关键问题。     

基于协议芯片的自动化设计通用模型

在IC设计中,HDL以其可移植性好、使用方便等优点几乎完全取代了传统的原理图输入方法,但使用HDL设计芯片也有编码效率低、开发周期长、调试困难等问题,为克服这些困难,提高IC设计的速度和准确率,结合实际项目经历提出一个适用于协议类型芯片的高效通用的自动化设计模型,借助HDL的描述和综合工具来实现,并以SerialATA芯片的链路层为例,说明设计过程。     

Arguing in Portugal: A cross-cultural analysis

We report data on Portuguese understandings of interpersonal arguing, based on a survey conducted in Portugal (N?=?252). Employing concepts and methods developed for studying interpersonal arguing, we report on the levels of argumentativeness, verbal aggressiveness, personalization of conflict, and argument frames. After comparing Portuguese men and women, we compare Portuguese respondents with two groups of US respondents. In contrast to US respondents, Portuguese report to argue more prosocially, cooperatively and civilly, and are more sophisticated in their reflections about arguing. We discuss these results in the context of the Portuguese notion of argumentation (argumentação) and Portuguese culture more broadly.

Getting Off to a Bad Start: The Relationship Between Communication During an Initial Episode of a Serial Argument and Argument Frequency

This study explores the relationships between features of an initial serial argumentative episode and the number of subsequent episodes. Initiators of the initial episode report a self-demand/partner-withdraw pattern occurs and this pattern is positively related to the number of subsequent episodes. Also, targets of the initial episode report that in the first episode they engaged in partner-demand/self-withdraw, and this pattern was positively related to their perception of constructive outcomes, but these constructive outcomes are not related to the number of subsequent episodes. Participants report that mutual hostility often results in partner-demand/self-withdraw, which is positively related to constructive outcomes. This model is produced in a sample of individuals in intact relationships and replicated in a sample of participants in terminated relationships.
