Reliable access to dynamics is one of the central challenges in humanoid robotics. In this paper we consider the problem of computing both internal and external wrenches in open multiple branches kinematic chains, which are not equipped with joint-level torque sensors, but on the contrary are provided with inertial and tactile sensing, and a set of six-axes Force/Torque Sensors (FTS) distributed within the chain. The proposed method is grounded on the Enhanced Oriented Graph, a graph-representation of the kinematic chain, enriched with the information coming from the different sensors. Under suitable conditions, a maximum of N+1 external wrenches can be estimated from N six-axes FTS. The graph is built dynamically, and internal and external wrenches are consequently updated. Theoretical results have been implemented in a software library (iDyn) released with an open-source license (GPL) as part of the iCub software project. The proposed method has been applied to 32 of the 53 DOF of the iCub humanoid robot. © 2011 IEEE.

In order to increase the coding efficiency of H.264/AVC, this paper proposed a parallelized approach of full search (FS) algorithm for motion estimation on Graphic Processor Unit (GPU) using computing unified device architecture (CUDA). By utilizing the independence among different MBs, we are able to take the full advantage of the computational power of CUDA and speed up the FS motion estimation by a large scale. Experimental results show that our implementation on CUDA can be as much as 50 times faster than existing CPU implementations.

Reducing our power consumption is an urgent issue which has important economical and ecological benefits. By using femtocell technology the mobile network can become far more energy efficient than it is today. In this paper, we describe what femtocell technology is and introduce outdoor femtocell distribution strategies that can save the network power. We also compare the usage of typical short-range base stations in place of femtocells and show that femtocells are more efficient. The results of the introduced strategies show that significant power savings of up to 92% can be achieved on a per-macrocell basis if implemented.

Watermarking capacity refers to the amount of information we are able to insert intothe image. Low signal to noise ratio is a phenomenon of watermarking channels which severely limits the capacity. The aim of this study was to develop a digital watermarking model which can find out the possibility to embed maximum amount of data in an image withoutdegrading the quality of watermarked image. In this approach, the host image will be partitioned into non-overlapping blocks and passing an imaginary plane in the three criticalpixels. The characteristics of this plan should not be changed after embedding message;then the same characteristics will be used to evaluate the embedded capacity in the extracting module. © 2011 Asian Network for Scientific Information.

mRNA polyadenylation is an essential mechanism in human genes and is direct linked to the termination of transcription. Alternative polyadenylation changes the length of the mature mRNA's 3′UTR. Since 3′UTRs have been shown to contain regulatory elements that control mRNA functioning, alternative polyadenylation plays an important role in controlling the expression of human genes. Prediction of polyadenylation sites can help with the identification of genes and aid our understanding of the mechanisms of alternative polyadenylation. In this study, we constructed a system for mRNA polyadenylation site prediction in human genes using SVM and based on an analysis of the sequence alignment between pair-end diTags (PET) and genome sequences. The PET sequences were mapped to the reference genome more accurate compared to earlier methods. We also analyzed single-site type and multiple-site type sequences PET sequence datasets and found that the frequencies of each nucleotide were different when the single-site type and multiple-site type PET sequences were compared. © 2011 IEEE.

This paper compared ACF(Auto Correlation Feature) characteristics for ZCD, Kasami and Golay codes. Sequence codes have been used as a spreading sequence in order to overcome ICI(Inter Code Interference) caused by transmitter and MPI(Multiple Path Interference) in receiver. In this paper, we abstracted characteristics of each spreading code and analyzed the properties of them. © 2011 IEEE.

This paper presents a new speed controller based on the theory of adaptive fuzzy inference system based on neural (ANFIS) for a direct torque to twelve sectors controlled of the induction motor. The proposed controller integrates fuzzy logic algorithm with a structure of artificial neural network (ANN) five-layer in order to reap the benefits of both methods, the learning abilities of the first and readability and flexibility of the second. The controller replaces the conventional PI is the rule fuzzy inference system with the hybrid learning algorithm. This makes learning the fuzzy system. The performance of the proposed neuro-fuzzy control for induction motor speed was studied at different operating conditions. The simulation study shows the robustness and relevance of control for applications in high performance driving.

Lack of hearing ability hinders deaf children from mastering grammar in language studies. Unfortunately, such software targeting Malay language is limited. This paper attempts to generate new approach in handling such software. These include detection of defects when switching into local languages, date format and accommodating the local laws. The acceptance of international software for local use goes beyond just these aspects. For this purpose, software that supports the multi-languages is evaluated. The main research question of this paper: The lack of cultural dimensions in localisation testing of assistive technology decreases the effectiveness of localisation testing of the localised software. On the account of cultural dimensions, Hofstede's Cultural Dimensions will be experimented to study which cultural dimensions are most suited for such software. From our empirical results, the failure rate of the testing is higher compared to incorporating culture dimensions.

No-reference quality evaluation is more difficult because it does not refer to any image. However, in some cases, like virtual view images, can not find the reference image, no-reference method had to be used. With the free viewpoint video technology development and application, measuring the performance of the multiview video system is essential and virtual view image quality evaluation is one of the key technologies in the system. The characteristic of virtual view image quality evaluation is that most of the virtual view images haven't reference images and can't be assessed using general measures such as PSNR of full-reference. Therefore, this paper proposed a no-reference image quality evaluation method based on image power spectrum. Experimental results show that the proposed method is consistent with PSNR.
