The control system of laser leveling machine was redesigned and tested to improve the performance and decrease the cost. In this paper, the control system of the machine which contains transmitter, receiver and controller was introduced. The receiver had silicon photoelements as photoelectric sensors. A kind of light filter was designed which was composed of red color optical glass and interfer...

The Eriksen Flanker task has been widely used as a measurement of cognitive control, however till now information is still scarce about how the neuroanatomical properties are related to performance in this task. Using voxel-based morphometry technique (VBM), the current study identified a set of distributed areas where the gray matter volume (GM) correlated positively with participants' efficie...

In this paper, we investigate the optimal power allocation strategy in a cognitive radio-based machine-to-machine (M2M) network where a licensed primary user and multiple unlicensed M2M devices coexist and operate in the same licensed spectrum. We develop a connectivity establishment mechanism in M2M network based on the cognitive radio scheme and propose an optimal power allocation scheme whic...

In this paper, we evaluate for the first time the use of Machine Translation technology to repair general errors in second language (L2) authoring. Contrary to previously evaluated approaches which rely exclusively on unilingual models of L2, this method takes into account both languages, and is thus able to model linguistic interference phenomena where the author produces an erroneous word for...

In this paper a tool system with wavelet support vector machine (WSVM) under dimension reduction for face recognition is proposed. Eigenfaces and fisherfaces are the major methods used to reduce the dimension of face images in the proposed face recognition tool system. At the same time, noise interference image cases, namely Gaussian noise, with no ears and no eyes are also considered in this p...

Workload consolidation is a technique applied to achieve energy efficiency in data centres. It can be realized via live migration of virtual machines (VMs) between physical servers with the aim to power off idle servers and thus, save energy. In spite of innumerable benefits, the VM migration process introduces additional costs in terms of migration time and the energy overhead. This paper inve...

Resource allocation plays a critical role to enhance the performance of cognitive orthogonal frequency division multiplexing (OFDM) network. However, due to lack the cooperation between cognitive network and primary network, the channel state information (CSI) between cognitive radio (CR) user and primary user (PU) could not be estimated precisely. In this work, a resource allocation problem ov...

introduction: determination of thyrotropin, total and free thyroxine and triiodothyronine are widely used as diagnostic methods for thyroid function evaluation. there have been numerous reports of interferences in thyroid hormone immunoassays. herein, a prominent positive interference is reported for a radioimmunoassay kit of total triiodothyronine. materials and methods: in this study, a total...
