This paper presents a new lumped-element absorptive bandstop filter topology. It exhibits infinite attenuation at the center frequency and no reflection regardless of the quality factor ($Q$ -factor) of the resonators. The new topology exhibits the absorptive characteristic with extremely low-$Q$ resonators, whereas an absorptive bandstop filter topology in the literature cannot be used for such...
There is a fast growing number of public spaces offering Wi-Fi access to meet the rising demands for Internet access. It is common for such service to be offered to users at no charge or for a flat fee. Both situations provide very little incentive for Wi-Fi providers to offer better service to the users. Similarly, Wi-Fi providers pay a monthly flat rate to ISP for Internet access and, this too does...
There is a fast growing number of public spaces offering Wi-Fi access to meet the rising demands for the Internet. It is common for such service to be offered to users at no charge or for a flat fee. Both situations provide very little incentive for Wi-Fi providers to offer better service to the users. Similarly, Wi-Fi providers pay a monthly flat-rate to ISP for Internet access, which does not incentivize...
The growing popularity for video based applications has put an enormous strain on the network and causes the network to be more prone to congestion. The study of congestion control and bandwidth allocation problems is often formulated into Network Utility Maximization (NUM) framework, and the existing solutions for NUM generally focus on single-layered applications. However, today's quality of video...
When natural disasters strike, network infrastructure is often completely destroyed, disabling communication; this significantly hampers rescue and relief efforts. Therefore, emergency communication network infrastructure must be deployed to provide communication at ground zero to rescue and relief agencies. The deployment strategy has to consider these humanitarian agencies' varying degrees of responsibilities...
Cellular Network Providers (CNP) provide users with wireless data access to meet the growing ubiquitous demand for the Internet. As users subscribe to a fixed data plan for a monthly flat fee, some users may exhaust their data allowance before the end of the billing cycle, while others underutilize their monthly quota. To take advantage of such underutilization, Khausik et. al. propose a mechanism...
Feedback mechanism based algorithms are frequently used to solve network optimization problems. These schemes involve users and network exchanging information to achieve convergence towards an optimal solution. However, in implementation, these algorithms do not guarantee messages will be delivered to the destination, especially when network congestion occurs, which in turn often results in packet...
Network Utility Maximization (NUM) framework has been extensively studied. Generally, existing solutions for NUM require message exchange between network and users to regulate the flow of network traffic, and information is frequently assumed to be available instantaneously and the traffic flow adjustment is accomplished immediately. However, realistically, there is delay in message exchange because...
This paper shows measurement of intraocular pressure (IOP) within a mouse eye. Three main challenges faced the development of a device for the measurement: the size of the mouse eye, the depth of the anterior chamber where the device will be implanted, and the maximum allowable incision size. These factors all limit the size of the device. In addition, a novel detection scheme is required which enables...
This paper presents the fabrication of an ultra-thin tag for identification and sensing applications in extremely small implantable regions. Particularly, we are demonstrating the capability to create a telemetry system which is implantable in a mouse eye. This system will eventually be able to monitor intraocular pressure (IOP). The small size of the mouse eye presents challenges for surgery and...
