This paper presents a simple method that computes test case coverage information from information on what files were updated to fix a fault found by the test case. It uses a cache to monitor fault-prone files and recommends test cases to rerun to cover updated files. We present an evaluation of the method during two months of development of a large,(More)
In most internationally recognized standardized multi-mode codecs, signal classification is performed in a single step by either linear discrimination or SNR-based metrics. The speech/music classifier of the EVS codec achieves greater discrimination than these single-step models by combining Gaussian mixture modelling (GMM) with a series of context-based(More)
The tracking of fading wireless channel is needed in MIMO-OFDM system. Training sequences can be used for synchronization and channel estimation. However, if too much training blocks are used, the efficiency of system will be decreased. A simplified training pattern which can reduce the waste of resources is proposed in this paper. Computer simulations(More)
With a view to wireless sensor networks, this paper formulates the objective of mobile agent route in terms of maximizing an objective function, which prefers the paths with higher signal accumulation, lower energy consumption, path loss and delay. Further, a genetic algorithm is proposed to compute such an optimal mobile agent route solution by suitably(More)
BACKGROUND Radix Paeoniae Alba, Radix Paeoniae Rubra, and Cortex Moutan are important Chinese herbs. Their bioactivities and efficacies are similar. However, they have different superior benefits clinically; so, a comprehensive investigation of the chemical difference is necessary and is of great importance for more reasonable quality assessment and proper(More)
This paper presents a new prediction model, which combines the clustering with neural network. The existed clustering algorithm has the shortcoming that can not determine the clustering number K, so this paper combines it with the concept of rough set to improve, and tests it on the IRIS data, Then this paper presents the new forecasting model which(More)
We report a patient who developed delayed cerebrospinal fluid (CSF) rhinorrhea 11 years after gamma knife radiosurgery for a growth hormone (GH)-secreting adenoma. The treatment dose was 18 Gy for the tumor margin (50% isodose). One year later, an MRI of the head revealed that the tumor size had decreased. Eleven years later, the patient developed CSF(More)
It's usually called the calculation of potentials on the cortex as the forward problem in the nerve system. Nowadays, the viewpoints of the equivalent source being regarded as the electrical activity of an excitable neuron have been widely accepted. In this paper, a novel method is presented to simulate the abnormal EEG morphology such as the spikes with(More)
BACKGROUND This study was designed to assess the levels of and associations between gay-related stressful events, social support, emotional distress and the number of unprotected anal intercourse partners among Chinese men who have sex with men. METHODS Using a respondent-driven sampling method, 807 men who have sex with men were recruited in urban areas(More)
An important problem in selective attention is determining the ways the primary visual cortex contributes to the encoding of bottom-up saliency and the types of neural computation that are effective to model this process. To address this problem, we constructed a two-layered network that satisfies the neurobiological constraints of the primary visual cortex(More)
