东巴经假借字的版本比较研究

纳西族信奉的东巴教是一种原始宗教,其经典称作东巴经.由于东巴教的传承方式是师徒间个别传授,东巴经也是世代传抄而保留下来的,不同的师承关系,所写的东巴经一般也形成了各自的风格.因而很难找到两本完全相同的经书.本文以早期经典<创世纪>的三个不同的版本为研究对象,比较来自同一地区同一种经典中的假借字的使用情况.

基于P（x）-Laplace流的向量值图像恢复模型

提出一种基于变指数型扩散方程的向量值图像（例如RGB图像或多谱图像）恢复模型。在新的模型中,我们利用光滑后向量值图像的几何流形特征来判断图像的真假边缘,利用P（x）-Laplace型扩散系数来控制扩散量和扩散方向。由于扩散系数具有良好的自适应判断边缘能力,新的模型在图像恢复的同时良好地保持了图像边缘。通过数值实验,对比以往的全变差模型,所提模型具有更好的图像恢复效果,明显减少了＂块状＂效应。     

门里门外谈——“门”字义项和使用规范

门是汉语里的一个基本词,发展至今,它的义项有31项之多。这些义项既反映了汉语社团的历史发展对词义的影响,也反映出民族间交流对词义的作用。本文分析门字所有义项的产生与相互关系,并就某些义项的使用提出规范化要求。     

Why Don't More Students Major in IS?

The large increases in the number of information systems (IS) majors about 10 years ago have been matched by equally large decreases in IS enrollments over the last few years. This article addresses the question of why students choose any major in general, and why students no longer choose to become an IS major in particular. We used a validated survey instrument and the responses from 163 students to examine this question in detail. Not surprisingly, we found that "genuine interest" in the subject was the most salient factor affecting the decision to major in IS. More surprising were what factors did not appear to influence this decision—for example, the promise of good job salaries, job security, the advice of others, or even the image of those who become IS professionals. Students seem aware that information technology employment opportunities exist; if job and salary issues contribute to choosing majors  other than IS , it is due to the perception of an unfavorable work/salary ratio for our field rather than one of job security or availability. That is, the amount of work to get an IS degree (the perception of harder-than-average courses) combined with (for many students) the perception of an undesirable amount of continuous training to keep an IS career just do not seem to balance with salary levels. These findings have important implications for the recruiting efforts of IS faculty seeking to attract more IS majors.     

基于流通日志的大学生借阅规律和影响因素的实证研究

在读者借阅行为的分析上,流通日志具有真实、准确和翔实等优点。本文对黑龙江某高校2014年9月至2016年8月的借阅日志进行了统计分析。发现在上、下学期的周、日、时视角下,借阅行为存在稳定的变化规律。相同年级学生借阅行为差异不显著。不同年级的学生借阅行为差异显著,读者年级是特定时段借阅差异的主要影响因素。

New method for high performance multiply-accumulator design

This study presents a new method of 4-pipelined high-performance split multiply-accumulator （MAC） architecture, which is capable of supporting multiple precisions developed for media processors. To speed up the design further, a novel partial product compression circuit based on interleaved adders and a modified hybrid partial product reduction tree （PPRT） scheme are proposed. The MAC can perform 1-way 32-bit, 4-way 16-bit signed/unsigned multiply or multiply-accumulate operations and 2-way parallel multiply add （PMADD） operations at a high frequency of 1.25 GHz under worst-case conditions and 1.67 GHz under typical-case conditions, respectively. Compared with the MAC in 32-bit microprocessor without interlocked piped stages （MIPS）, the proposed design shows a great advantage in speed. Moreover, an improvement of up to 32% in throughput is achieved. The MAC design has been fabricated with Taiwan Semiconductor Manufacturing Company （TSMC） 90-nm CMOS standard cell technology and has passed a functional test.
