A Low Power High Speed Mobile Memory I/O Interface Using Reconfigurable Multi-Band Multi-Modulation Signaling, Yue Yu
Electrical Engineering Theses and Dissertations
This research mainly focuses on the design of a novel memory I/O interface with high bandwidth and high energy-efficient for mobile computing systems in order to dramatically enhance the circuit and system bandwidth and power efficiency. The proposed memory I/O interface, exploiting multi-modulation and multi-band signaling, is capable of supporting simultaneous bidirectional data transition of 4 separate data streams across a single-ended off-chip transmission line to achieve both high speed data rate and low power consumption. This multi-band multi-modulation interface (MMI) consists of multiple RF-band transceivers which utilize ASK modulation, and baseband transceivers which utilize 4-PAM modulation to increase the …
Spatial Division Multiplexing Using Ince-Gaussian Beams, Sahil Sakpal
Spatial Division Multiplexing Using Ince-Gaussian Beams, Sahil Sakpal
Electrical Engineering Theses and Dissertations
In space division multiplexing (SDM) the spatial modes of a multimode optical fiber are used as individual data channels. SDM gives another degree of freedom over wavelength for increasing data transmission rates. As a result, SDM is a potential solution for more than 400Gbit/s requirements in data centers where scaling data transmission rates with parallel single mode optical fibers is currently ubiquitous. However, due to mode coupling, i.e., spatial modes exchange of power, SDM may require multiple inputs multiple output digital signal processing (MIMO-DSP) to mitigate resulting mode crosstalk, the cost and complexity of which may be prohibited in data …
Securing Database Users From The Threat Of Sql Injection Attacks, Nisharg Shah
Securing Database Users From The Threat Of Sql Injection Attacks, Nisharg Shah
Electrical Engineering Theses and Dissertations
In the 21st century, there has been a significant rise in dependency on the Internet for daily activities. Web applications such as online banking, web-based emails, social networking, and many more services have become an instant means of communication. These web applications and the data to which they have access are often targeted using malicious attacks, including SQL (Structured Query Language) Injection Attacks (from now on referenced as SQLIAs), which may cause serious damage. In particular, attackers use SQLIAs to target interactive web applications that incorporate database services. In a SQLIA, an attacker can insert malicious SQL code as …
