In MPEG standard, motion estimation (ME) is used to eliminate the temporal redundancy of video frames. This ME is the most time-consuming task in the encoding of video sequences and is also the one using the most power. Using low-bit images can save power of ME and a conventional architecture fixed to a certain bit width is used for low-bit motion estimator. It is known that there is a trade-of...

Flexibility and Portability has increased the requirement of Low Power components in fields like multimedia, signal processing and other computing applications. Adders are the essential computing elements in such applications. However the present adder architectures with hybrid/heterogeneous features provide performance variations but limits to consume less power. In this paper, low power heter...

We have developed a humanoid robot HRP-1S that is capable of simultaneous whole body motion control. In phase one of the Humanoid Robotics Project (HRP) of the Ministry of Economy, Trade and Industry of Japan, Honda R&D Co. Ltd has produced humanoid robot HRP-1 as a humanoid research platform to ease the development of good applications for humanoid robots in phase two of HRP. However, HRP-1 co...

This paper aims to identify key challenges facing Iran and South Korea in their bilateral trade and investment relations. In particular, it is concerned with the policy implications which can be useful for policy makers and business people of both countries. For this purpose, we review and analyze the recent developments of the Iranian economy and bilateral trade and investment relations betwee...

We investigate the secret key agreement from correlated Gaussian sources in which the legitimate parties can use the public communication with limited rate. For the class of protocols with the one-way public communication, we show a closed form expression of the optimal trade-off between the rate of key generation and the rate of the public communication. Our results clarify an essential differ...

Concerns regarding the Trans-Pacific Partnership (TPP) have raised awareness about the negative public health impacts of trade and investment agreements. In the past decade, we have learned much about the implications of trade agreements for public health: reduced equity in access to health services; increased flows of unhealthy commodities; limits on access to medicines; and constrained policy...

The speech denoising Neural Network architecture we propose in this paper is based on Adaptive Spline Neural Network (ASNN). It is an architecture for real-time oriented applications, due to its low size complexity and high parallelism. Results show improvements in Signal to Noise Ratio (SNR) and better performances in comparison with classical denoising neural networks. Key-Words: Speech Enhan...

The paper presents a new type of parallel router architecture based on a combinatorial arrangement of routing processing elements. The suggested approach reveals some properties of combinatorial designs, useful for economical implementation of parallel routing. In particular, such an architecture has explicit advantages for packet switching and multicast routing implementation. Key-Words: packe...

In this paper we propose a new pipelined architecture for the LMS adaptive filter which can be implemented with less than half the amount of calculation needed for the conventional architectures. Even though the proposed architecture reduces the required calculation, it can simultaneously produce good convergence characteristics, a short latency and high throughput characteristics. key words: a...
