Due to the pressure from work load and daily life, there is an increase in geriatric depression population. However, some people may not notice or have no idea about the symptom of melancholia. More research input is needed to diagnose severity of melancholia at an early stage. To help users diagnose their physical fitness and mental health condition before outpatient service, two approaches are considered...
This research develops a scaffolding environment to enhance English writing instruction that provides process-oriented writing supports for cause and effect essays. It enhances students' experiences in writing planning and translating processes by helping students realize step-by-step nature of technical English writing. The scaffolding support, based on the topic, will guide students to write essays...
In this paper, we propose a peak-to-average power ratio (PAPR) reduction method for an orthogonal frequency division multiplexing (OFDM) system by combining the improved genetic algorithm used the partheno-crossover operator (PCGA) with partial transmit sequence (PTS) scheme, called PCGA-PTS. Recently, the genetic algorithm based PTS scheme (GA-PTS) is a novel PAPR reduction method, which has lower...
In recent years, the target of the denial-of-service attacks, such as the Http flooding attack, have been switched from the network layer to the application layer. Various attacking schemes are adopted by the attackers to break down the Web site server, some of them send tremendous amount of packets to break down the target host, others send specific request packets to keep the Web site server busy...
In order to monitor the cosmic radiation exposure level onboard aircraft in accordance with the national standard about radiation safety, a computer system CARD has been developed using to calculate cosmic radiation effective dose in flight. In this paper, the principle of development, structure and function of the CARD were described. The cosmic radiation effective doses received by aircrews in flight...
We extend the sharing scheme proposed by Mignotte in 1983 based upon Chinese remainder theorem (CRT) to devise a threshold secret sharing scheme for digital images. Given a secret image I and a set of n participants sharing I, our scheme encrypts I into n shadows in such a way that any group of r shadows can recover I while that of less than r shadows cannot where 2 les r les n. As compared to the...
