A Diffie-Hellman public-key cryptography based on chaotic attractors of neural networks is described in the paper. There is a one-way function between chaotic attractors and initial states in an overstoraged Hopfield neural network (OHNN). If the synaptic matrix of OHNN is changed, each attractor and its corresponding domain of initial state attraction is(More)
There are race conditions in concurrent programs if the accesses to a sharing resource are not properly synchronized. Because the races can cause the program to behave in unexpected ways, detecting them is an important aspect of debugging and program verification. Many approaches have been used to detect race conditions, but there still is no effective(More)
Osteonecrosis of the femoral head is a severely disabling complication of steroid immunosuppression in renal transplant patients. The increased number of patients undergoing transplantation has increased the number of transplant recipients undergoing total hip replacement arthroplasty (THRA). In this study, we retrospectively assessed patients who underwent(More)
In this paper, a new algorithm of feature parameter extraction is proposed for application in speaker recognition system, which combines the traditional MFCC and the dynamic MFCC as a new series of coefficients. According to the statistics analysis of the different contribution by the dynamic MFCC and traditional MFCC, these coefficients are weighted as(More)
Intravenous leiomyomatosis is a rare variant of leiomyoma that could result in death. Early and accurate diagnosis and appropriate treatment strategies play a dominant role in good prognosis. Eighteen cases of Intravenous leiomyomatosis , along with clinicopathologic data, were retrieved from our database. Most of the patients who ranged in age from 33 to(More)
A novel transform-domain image watermark based on chaotic sequences is proposed in this paper. A complex chaos-based scheme is developed to embed a gray-level image in the wavelet domain of the original color image signal. The chaos system plays an important role in the security and invisibility of the proposed scheme. The parameter and initial state of(More)
Nitrogen (N)-doped carbon materials exhibit high electrocatalytic activity for the oxygen reduction reaction (ORR), which is essential for several renewable energy systems. However, the ORR active site (or sites) is unclear, which retards further developments of high-performance catalysts. Here, we characterized the ORR active site by using newly designed(More)
Now days, different kinds of IDS systems are available for serving in the network distributed system, but these systems mainly concentrate on network-based and host-based detection. It is inconvenient to integrate these systems into distributed application servers for application-based intrusion detection. An agent-based IDS that can be smoothly integrated(More)
Software fault localization techniques typically rank program components, such as statements or predicates, in descending order of their suspiciousness (likelihood of being faulty). During debugging, programmers may examine these components, starting from the top of the ranking, in order to locate faults. However, the assigned suspiciousness to each(More)
