Description: Recent peer-to-peer (P2P) systems are characterized by decentralized control, large scale and extreme dynamism of their operating environment. As such, they can be seen as instances of complex adaptive systems (CAS) typically found in biological and social sciences. Anthill is a framework to support the design, implementation and evaluation of P2P applications based on ideas such as multi-agent and evolutionary programming borrowed from CAS. An Anthill system consists of a dynamic network of peer nodes societies of adaptive agents travel through this network, interacting with nodes and cooperating with other agents in order to solve complex problems. Anthill can be used to construct different classes of P2P services that exhibit resilience, adaptation and self-organization properties. Platform: |

Description: Orthogonal Frequency Division Multiplexing
(OFDM) has been adopted by most wireless and wired communication standards these include wireless Local Area Networks (LANs) HyperLan2, 802.11a, broadband wireless(802.16) and lately the 802.15.3c for millimetre wave communications. In parallel, Field-Programmable Gate Arrays (FPGAs) have become an alternative for the implementation of those standards, due to their increased capabilities (speed and resources). This work introduces the design and performance evaluation of an OFDM transceiver, implemented on a FPGA platform for applications on a wireless millimetre wave radio system, operating around 60GHz.-Orthogonal Frequency Division Multiplexing

Description: The output characteristics of a photovoltaic (PV) array are highly non-linear. Therefore, an accurate andefficient PV model is required to study and analyze the operation of PV system in the changing environ-mental conditions. This paper proposes a precise PV simulator based on the seven-parameter electriccircuit model. The proposed simulator can generate the output characteristics of a PV system preciselyat different operating conditions. It has also enough flexibility to simulate different configurations ofPV panels with series/parallel connections. The robustness of the proposed simulator is demonstratedunder the partial shaded conditions. Additionally, the performance of the developed simulator is verifiedby interfacing it with the actual power electronic converter and maximum power point tracking (MPPT)controller. The proposed PV simulator will facilitate the design aspects of PV systems and help in behaviorassessment of newly developed controllers prior to practical implementation. Platform: |

Description: 以USBKey作为密钥存储载体和身份认证实体，来实现对文件的一种基础加密功能。UsbKey是一个集身份认证、密钥安全存储、对称钥和非对称钥加密等安全功能于一体的安全硬件，是一种带有USB接口的加密锁。因为USB KEY是一种比较简化型的加密锁,不需要任何驱动程序。并且它具有极高的加密强度,用硬件保存密码,用软件配合来使用。并且携带方便,简单易用,性能稳定。安全操作系统启动后通过插入UsbKey对于用户的身份进行认证 通过把密钥安全存储在UsbKey中,能够防止泄漏、篡改。本次设计使用epass系列usbkey，里面的算法实现以下主要两个简单的功能：
加密：可以通过调用USBKey中的算法或自己实现算法进行本地文件加密
解密：先进行身份认证的基础上，读取USBKey中的密钥将文件解密
除此之外，我们还可以增加删除文件的功能。
