Implementation of Smart Car Using Fuzzy Rules

We proposed an algorithm to automatically control the seat, and notify dangerous traffic conditions for smart car system. The system is needed to adapt to both the driver and the circumstance for maximum convenience and safety. In order to solve these problems, we proposed an algorithm for developing smart vehicles.

A Study on the Design of the Efficient Adder and Multiplier Based on Normal Basis over Finite Fields

This paper propose the method of constructing the highly efficiency adder and multiplier systems over finite fields. The addition arithmetic operation over finite field is simple comparatively because that addition arithmetic operation is analyzed by each digit modP summation independently. But in case of multiplication arithmetic operation, we generate maximum k = 2m − 2° of αk terms, therefore we decrease k into m − 1 using irreducible primitive polynomial. We propose two method of control signal generation for the purpose of performing above decrease process. One method is the combinational logic expression and the other method is universal signal generation.

Universal Multiple Processing Unit Using Graph

This paper presents a method of constructing the universal multiple processing element unit(UMPEU) based on Graph. The proposed method is as following. Firstly we propose transformation operators in order to construct the graph using properties of graph. Secondly we construct the transformation table of graph using above transformation operators. Finally we construct the graph using transformation table. The proposed UMPEU is capable of constructing the graph for any prime number and integer value of finite fields. Also the UMPEU is applied to fault-tolerant computing system, pipeline class, parallel processing network, switching function and its circuits.

Efficient common radio resource management techniques for cloud systems

This paper proposes resource management method for effieicnt wirless network resource management by applying Common Radio Resource Management(CRRM), which is efficient in managing overlapped heterogeneous wireless network, to cloud computing environment. When the congestion increases, the suggested method utilizes CRRM and forces users who are connected to it to move to other mobile network to solve its own congestion.

Construction of Sequential Digital Systems over Finite Fields

This paper presents a method of constructing the sequential digital systems over finite fields. We assign all elements in finite fields to digit codes using mathematical properties of finite fields. Also, we discuss the operational characteristics and properties of the building block T-gate which is used to implement the sequential digital systems over finite fields. Then, we implemented sequential digital systems without feed-back. The sequential digital systems without feed-back is constructed as following steps. First, we assign the states in state-transition diagram to state digit codes, then obtain the state function and predecessor table which is explaining the relationship between present states and previous states. Next, we obtained the next-state function from state function and predecessor table. Finally we realize the circuit using T-gate and decoder. The proposed method is more efficiency and systematic than previous method.
