Description: 题目：设计一个请求页式存储管理方案，并编写模拟程序实现
具体要求：
1、产生一个需要访问的指令地址流，为不失一般性，可以适当地（用人工指定地方法或用随机数产生器）生成这个序列，使得 50％的指令是顺序执行的。25％的指令均匀地散布在前地址部分，25％的地址是均匀地散布在后地址部分
2、 页面淘汰算法采用 FIFO页面淘汰算法，并且在淘汰一页时，只将该页在页表中抹去。而不再判断它是否被改写过，也不将它写回到辅存
3、产生一个需要访问的指令地址流；指定合适的页面尺寸（例如以1K或2K为1页；指定内存页表的最大长度，并对页表进行初始化
4、每访问一个地址时，首先要计算该地址所在的页的页号，然后查页表，判断该页是否在主存。如果该页已在主存，则打印页表情况；如果该页不在主存且页表未满，则调入一页并打印页表情况；如果该页不在主存且页表已满，则按 FIFO页面淘汰算法淘汰一页后调入所需的页，打印页表情况 。逐个地址访问，直到所有地址访问完毕

Description: This dissertation contributes a jam-resistant communications protocol for use in
mobile ad-hoc network (MANET). Speci c focus is given to the network layer rout-
g of packets within a MANET. A MANET is a self-organizing multi-hop wireless
twork that is comprised of many mobile hosts communicating wirelessly. As a result
their mobility and dependence on wireless communications, network layer routing
especially prone to errors. An algorithm has been developed using the concept concurrent codes to allow for jam-resistant wireless communications without a pre-
shared secret. The algorithm allows for the recovery of messages even in the presence
of signi cant noise. Experimental results show that a cross-layer protocol designed
to take advantage of this property allows for more e ective communications in noisy
environments such as disaster sites where current network protocols experience signif-
icant packet loss rates. Ultimately, this research presents a communications protocol

Description: 光伏电池阵列输出功率受光照强度和温度变化的影响，因此最大功率点跟踪（MPPT）技术广泛应用于光伏系统中。在所有最大功率点(MPP)控制策略中，扰动观察（P&O）MPPT算法因易实现被广泛应用，然而它的缺点是在稳定工作状态下工作点通过MPP 时会导致能量振荡损耗，并且在光照强度或温度发生突变时表现较差的动态响应。在本文中，提出一种改进型变步长扰动观察MPPT 算法，此方法依据工作点动态调整步长变化，与传统固定步长方法比较，本文提出的方法能有效地提高MPPT 速度和转换效率，通过仿真和实验结果分析，验证了此改进算法的可行性。-PV array output power by the light intensity and temperature changes, the maximum power point tracking (MPPT) technology is widely used in photovoltaic systems. In all the maximum power point (MPP) control strategy, the disturbances observed (P & O) MPPT algorithm due to easy implementation is widely used, but its drawback is that the steady-state operating point by MPP will lead to energy oscillations loss, and in the light intensity or temperature when the poor performance of a mutation in the dynamic response. In this paper, propose a modified variable step disturbance observed MPPT algorithm, this method dynamically adjusted according to operating point step change, with the more traditional fixed-step method, the proposed method can effectively improve the MPPT speed and efficiency, The simulation and experimental results verify the feasibility of this improved algorithm.

Description: A closed-loop power control system
having both fixed-step and adaptive-step power
control algorithms and incorporating with
multitap RAKE receivers was proposed.
Simulations were performed for wide-band radio
channels having path loss, slow fading, and fast
fading. As the measurement of the received power
and the bit energy-to-interfkrence power spectral
density ratio play an important role in a CDMA
power control system, a scheme to estimate these
two parameters was proposed. For a Rayleigh
fading channel and a Rician fading channel
having a K factor of 6dB, a three-tap RAKE
receiver is desirable.
