OBJECTIVE To identify the magnetic resonance (MR) features of a group of pediatric patients with Leigh syndrome (LS) caused by SURF1 gene 604G-->C mutation. MATERIALS AND METHODS Eight cases with definite diagnosis of SURF1 gene 604G-->C mutation in our hospital were reviewed. Most cases presented typical symptoms in their infancy or childhood, with(More)
We present an improved mobile Ad Hoc Network on-demand routing protocol which based on AODV by controlling the broadcasting of RREQ information. This protocol analysis the lifetime of node when implementing routing discovery, and avoiding the unnecessary information sending efficiently. By compare AODV with IAODV in the same scenario, the new protocol is(More)
Data clustering is a necessary process in many scientific disciplines, and fuzzy c-means (FCM) is one of the most popular clustering algorithms. Recently, distributing weight values and avoiding local minimization are the possible ways to improve the results of FCM. In this paper, fuzzy Cmeans clustering based on weights and gene expression programming(More)
This paper presents a design of a a high-precision shaft angle acquisition system used in the solar panel by the implementation of absolute round induetosyn as angle sensor, the Direct Digital Synthesizer (DDS) and resolver to digital converter (RDC), and the AVR micro controller which is used as the central processor. This paper also introduces the(More)
OBJECTIVE The purpose of this study was to explore the underlying clinical factors associated with the degree of retinal hemorrhage (RH) in full-term newborns. METHODS A total of 3054 full-term infants were included in this study. Eye examinations were performed with RetCamIII within one week of birth for all infants. Maternal, obstetric, and neonatal(More)
The Star Sensor can be used to assist the inertial navigation system (INS) for navigation and positioning, restraining the accumulated error caused by the inertial components. During the integrated navigation process, the Star Sensor is installed above the INS, generated installation errors between the INS body coordinate system and the Star Sensor body(More)
Lock-free algorithms provide a new way for thread synchronization, it avoid some common problems encountered in traditional synchronization methods. But the implementation of lock-free algorithm is generally complex. The lock-free queue algorithm described by Maged M. Michael and Michael L. Scott was fast and simple, its implementation using C++ under(More)
BACKGROUND The General Practice Department of Fudan University recognised that a traditional didactic educational approach will not achieve expected learning outcomes. Therefore, the Department adopts an integrated learning and teacher-centred approach. AIM To evaluate the effect of introducing integrated learning and a teacher-centred approach to(More)
The fault diagnosis model of steam turbine based on Bayesian network is direct impacts on the complexity of the diagnostic process, so the construction of Bayesian network model is the primary problem. According actual fault diagnosis system of steam turbine containing redundancy and uncertain information, proposed attribute reduction method to fault(More)
In order to reduce the influence on horizontal misalignment, which is caused by external velocity error under the external damping mode in Strapdown Inertial Navigation System (SINS for short), the technology of dual-system parallel processing is presented in the SINS calculation. Solution system 1 is the same as traditional solution model, in which log(More)
