A new method of speech enhancement is proposed based on morphological filter and wavelet transform.The system begins by first conducting morphological filtering,then distinguishing the unvoiced,voiced and noise using TEO in the wavelet domain.It then executes wavelet transform using different threshold on multiscale,and at the same time to improve the threshold function.Experimental results showed that the method not only suppressed noise effectively but also reduced the loss of the unvoiced.It also not only enhanced SNR,but also improved voice clarity and comfort.The merits it espouses makes it an effective speech enhancement algorithm.

The design of modern radiofrequency integrated circuits on silicon operating at microwave and millimeter-waves requires the integration of several spiral inductors, transformers and transmission lines, which are commonly not available in the process design-kits of the technologies. Moreover, the design and simulation of such devices are not addressed adequately by means of systematic techniques and automation.

To resolve the limitation of information safety and transmission speed in existing communication system,it applied the modular design method to design optical-electric combined THz wireless communication system framework,and determined 125GHz carrier frequency.Aiming at the core component optical emitter uni-traveling-carrier photodiode(UTC-PD) in THz wireless communication system,it analysed the relationship between output power,bandwidth and input signal types,and determined the emitter bandwidth by experiment.The result shows that the transmission speed in the system is able to reach 3.0Gbps when BER is less than 10-10.

The system which could be described as "trinity,seven subsystems" has realized automatic remote control of the machine working process with orientation,localization and formalization.At local place,it realized automatic position and pose online detection,automatic orientation tunneling,automatic section cutting and forming and adaptive control of cutting arm swaying speed,it was the first time that realized absolute measuring of roadheader frame position and pose error under coal mine working condition in our country which could avoid error accumulation in relative measuring and guarantee the high precision of orientation tunneling.In underground remote,it realized remote monitoring,wireless remote control and video surveillance,thus realized remote control with multiple angles,visualization and one-button control under the condition of dustiness and vibration.At any network access point on ground using mining ring network,it realized real-time monitoring and displaying of roadheader running state parameters,and realized the functions of remote fault diagnosis and alarming.The whole system has been tested many times underground.The application results show that it is stable and reliable.With the development of automation,intellectualization,and informatization and other high technology,this system will be more and more suitable for fully mechanized excavation face.

To further improve the accuracy of SAR image segmentation in the marine spill oil detection,a segmentation method of marine spill oil images based on Gabor,Krawtchouk moments and KFCM is proposed in this paper.Firstly,the marine spill oil image is decomposed by Gabor transform to obtain the texture features of image.Then,the Krawtchouk moments are applied to extract the shape features of image.Finally,the image segmentation is achieved based on KFCM.A large number of experimental results show that,compared with the related segmentation methods such as Tsallis entropy threshold method,CV model method and the method based on Gabor,Krawtchouk moments and FCM,the proposed method can achieve better result.

Phablet is a portmanteau of the words phone and tablet , which is a class of mobile device designed to straddle the functions of a smartphone and tablet. Phablets typically have screens that measure (diagonally) between 5.01 and 6.9 inches, which complement screen-intensive activities such as mobile web browsing and multimedia viewing. Phablets also include software optimized for an integral self-storing stylus to facilitate sketching, note-taking, and annotation.

In this paper,we present a new approach to improve extracting accuracy of impervious surfaces.One Landsat TM image of Taiyuan city,Shanxi Province of China was used.After doing test work and analyzing using optimum bands analysis,principal component analysis,and normalized difference impervious surface index,we present the method,optimized band combination.Both unsupervised and supervised classification methods were used to classify the original image,principal component analysis image,normalized difference impervious surface index image,and optimized band combination images we present.The accuracies result of these classifications were assessed by using 256 randomly selected sampling points,and it was found that the overall accuracy the accuracy of optimized band combination method can be reach 87.72％,with the Kappa statistic of 0.85 in impervious surface extraction,it was better than other three methods can get.
