This letter mathematically proves that the performance of the new protocol in Ref. [1] is better than that of the existing protocol. It was proposed that a frame from an access device is delivered over the access link and then it is multiplexed and packed into ATM cell at an access node and then the cell is carried toward a voice gateway, by using a method to split two sublayers in AAL2. That means one sublayer is implemented at the subscriber access device and the other sublayer is implemented at the access node. Access devices using the protocol achieve higher utilization of CID and waste fewer ATM resource per the access device. Mathematical analysis is performed on the proposed and existing protocol, and both upstream cell rate and padding probability are calculated. The proposed protocol shows lower upstream traffic rate and padding cell probability than the existing protocol.

In this letter, we propose a protocol sensitive random early detection algorithm for active queue management to improve fairness between TCP and UDP flows and to reduce delay time with small overheads. The algorithm classifies the packets into responsive and unresponsive flows, and applies the RED algorithm individually to each classified group. Using ns-2 simulations, we showed the effectiveness of the proposed PSRED algorithm compared with several well-known AQM schemes, such as RED and RED-PD algorithms.

This paper presents a personal identification method based on BMME and LDA for images acquired at anterior and posterior occlusion expression of teeth. The method consists of teeth region extraction, BMME, and pattern recognition for the images acquired at the anterior and posterior occlusion state of teeth. Two occlusions can provide consistent teeth appearance in images and BMME can reduce matching error in pattern recognition. Using teeth images can be beneficial in recognition because teeth, rigid objects, cannot be deformed at the moment of image acquisition. In the experiments, the algorithm was successful in teeth recognition for personal identification for 20 people, which encouraged our method to be able to contribute to multi-modal authentication systems.

The authors present a shaper for handling non-real time cell traffic which can avoid the cell loss caused by the policing function at the next hop. A state-dependent probabilistic scheduling algorithm which selects a proper queue for cell transmission is introduced. For the purpose of performance evaluation, the cell loss ratio of the proposed shaper is evaluated by simulation.

Radio frequency (RF) microwave can be used to predict glucose concentration in a sample. This paper presents preliminary results in determining the concentration by measuring relative permittivity in the solutions of distilled water, saline, human serum, and human blood containing glucose. In the experiments, sensitivity for detecting glucose concentration in blood solutions was almost 57 mg/dl at the frequency of approximately 5.8 GHz.
