Recently, the opportunistic incremental relaying systems have been studied to improve the system performance effectively in wireless fading channel. Most of the performance analysis of the system includes a source-destination direct link. And there are few analysis which consider source-relay-destination indirect paths only. Therefore this paper proposes a transmission protocol which relays the source information using the selected relay from the partial channel information at the first stage in an opportunistic incremental relaying system. If the transmission fails, the selected best relay from the full channel information retransmits the information to the destination incrementally. The performance of the proposed system is derived analytically and verified from Monte Carlo simulation. The derived results can be applied to the system design and the performance estimation of the mobile systems and the bidirectional TV broadcasting systems which adapt an opportunistic incremental relaying system.

VHDL simulation requires both analysis and elaboration processes. Reducing the time taken by these processes shorten design cycles. We propose an incremental analysis and elaboration algorithm for VHDL, which minimizes the number of design units to be re-analyzed and re-elaborated after an incremental change, thereby reducing the desing cycle time. Experimental results show about four times performance improvement in analysis and 1.25 times in elaboration over the conventional method.

In the original incremental Extended Horizon Control, the control inputs are computed recursively each step in the prediction horizon. But in this paper, we propose another incremental Extended Horizon Self-tuning Control version in which control inputs can be computed directly in any time interval. The effectiveness of this algorithm in a variable time delay or load disturbances environment is demonstrated by computer simulation. The controlled plant is a nonminimum phase system.

In this paper , we propose an incremental approach for recognizing a class of machining features from a featurebased design model as a part design proceeds, utilizing various information such as nominal geometry, design intents, and design feature characteristics. The proposed apptroach can handle complex intersecting features and protrusion features designed on oblique faces. The class of recognized volumetric machining features can be expressed as Material Removal Shape Element Volumes (MRSEVs), a PDES/STEP-based library of machining features.

This paper proposes incremental LR parsers which are constructed by using pre-determinable reduction goal. The new method requires a relatively small number of memory space and computing time compared to the previous methods.

In order to increase the productivity of software, the research to reduce the total cost in software development environments is working, Considerable time is wasted waiting for a changed program in program development, however smell the change, to be edited and compiled and executed. In case of partial change, we need incremental interpreter for reexecuting the changed parts and its affected parts, In this paper, we implement the incremental interpreter by using analyzing dynamic semantics at execution time, We define a new IMPLO(IMPerative Language with Object) language using EBNF(Extended Backus Naur Form) notation and then, design and implement the incremental interpreter of this language by using action equations to describe the dynamic semantics.

Since protecting the environment became a major issue in modern society, an increasing number of individuals have engaged in lifestyles of health and sustainability (LOHAS). The purpose of this study is to investigate the effects of restaurant and LOHAS images on customer satisfaction and loyalty. Particularly, this study analyzes the incremental information content of LOHAS image in the relationship between restaurant image and customer satisfaction/loyalty. A self-administered questionnaire was distributed to customers of casual-dining restaurants in three major cities (i.e., Seoul, Daegu, and Busan) in South Korea. The empirical findings suggest significant incremental information content of LOHAS image beyond general restaurant image in explaining customer satisfaction and loyalty.

In this paper, we propose a new method which estimates the initial position of a PM synchronous motor (PMSM) using an incremental ecoder. in cremental encoders are widely used in detecting rotor position since they are inexpensive. At starting procedure, however, the incremental encoders cannot give the information of the absolute rotor position. Hence, additional absolue encoder, which has $60^{\circ}C$ resolutio electrically, and signal lines called U, V, W, have been used in practical systems for starting injection of a high frequency test current. It does not require any additional information such as U, V, W signals for starting procedure and allows for cheap and simple implementation. Experimental results show that the proposed method can estimate the initial rotor positon with higher accuracy than the conventional method using U, V, W signals.

The incremental learning method performs well in face face tracking. However, it has a drawback in that it is sensitive to the tracking error in the previous frame due to the environmental changes. In this paper, we propose a selective incremental learning method to track a face more reliably under various conditions. The proposed method is robust to illumination variation by using the LBP(Local Binary Pattern) features for each individual frame. We select patches to be used in incremental learning by using Staggered Multi-Scale LBP, which prevents the propagation of tracking errors occurred in the previous frame. The experimental results show that the proposed method improves the face tracking performance on the videos with environmental changes such as illumination variation.

This paper presents a low power and high resolution incremental delta-sigma ADC that utilizes a passive integrator instead of an opamp-based active integrator. Opamp is a power-hungry block that involves tight design tradeoffs. To avoid the use of active integrator, the s-domain characteristic of an active integrator is first analyzed. Based on the analysis, an active integrator with low gain design is proposed as an alternative design method. To save power even more aggressively, a passive integrator with no static current is proposed. A 1st order single-bit incremental delta-sigma ADC using the proposed passive integrator is implemented in a 65nm CMOS process. Transistor-level simulation shows that the ADC consumes only 0.6uW under 1.2V supply while achieving SNDR of 71dB with 22kHz bandwidth. The estimated total power consumption including digital filter is 6.25uW, and resulting power efficiency is on a par with state-of-the-art A/D converters.
