In some legal systems property passes at the time of the conclusion of the contract. In other legal systems property passes at some later time such as the time at which the goods are delivered to the buyer. It was not regarded possible to unify the rule on this point nor was it regarded necessary to do so since rules are provided by this CISG for several questions linked, at least in certain legal systems, to the passing of property. Even though the CISG rules that it does not govern the passing of property in the goods sold, it does not exclude completely the effect which the contract may have on the property in the goods sold. Problems that under some domestic systems are decided by reference to the "property" concept are governed by specific provisions of the CISG. First of All, the CISG(Arts. 41 and 42) deals with seller's obligation to the buyer that the goods be free of third party claims. Moreover, Article 45 gives a buyer the right to require the seller to deliver goods that the seller wrongfully withholds. Secondly, Article 81(2) gives a seller the right to claim restitution of goods for which the buyer fails to pay. Domestic law must respect these rights as between the seller and buyer; if such rights between the parties prevail over the claims of creditors or other third parties under domestic law, domestic tribunals should give the same effect to rights established by the CISG. Thirdly, the right to sell the goods arises where there has been an unreasonable delay by the party in taking possession of them or in taking them back(Article 88).

This paper proposes a novel adaptive header-based power gating structure to compensate for the performance loss and the increased wake-up time of the power gating structures induced by the negative bias temperature instability (NBTI) effect. The proposed structure consists of variable width footers based on the two-pass power gating and a new NBTI sensing circuit for an adaptive control. The simulation results of the proposed structure are compared to those of power gating without the adaptive control and show that both the circuit-delay and wake-up time dependence of the power gating structure on the NBTI stress is minimized with only 3% and 4% increase, respectively while keeping small leakage power and rush-current. In this paper, a 45 nm CMOS technology and predictive NBTI model have been used to implement the proposed circuits.

'Low Carbon, Green Growth' may be the achievable target in industry section, depending on whether less reliance on fossil-fuels use can bring higher productivity growth in the long run. This paper tests for the short-run and long-run effects of investment on energy-saving equipments on productivity growth in the Korean manufacturing industries. The investment in energy efficiency causes an increase in costs (measurement effect) in the short-run, but in the long-run likely improve energy intensity and reduce costs (positive real effect) despite the delay in new other investment for technical innovation (negative real effect). A 2SLS regression was attempted to deal with endogeneity of energy-saving investment. The productivity effects were tested for five manufacturing sub-industries showing relatively high energy intensity with annual time series data from 1982 through 2006. No productivity effects were accepted for all five sub-industries except Chemical products. Positive real effect was considered to be exceeded by negative real effect, resulting in decreased productivity growth for Chemical products.

In the mobile vector map service environments, there are problems like as terminal resource shortage and transmission delay for the characteristics of large spatial data. For the normal mobile vector map services, some techniques are required to overcome the problems. Spatial data compression approach is one of the techniques to reduce the bandwidth and the waiting time at clients. However it also must be considered that the effect on total efficiency caused by the overhead of compression and restoration time. This thesis proposes two spatial data compression techniques. First approach is to get relative coordinates to first coordinate of each object. The other approach is to compute client coordinates before transmission. Through the implementation and experiments, proposed techniques are evaluated the compression effects and efficiency.

Analysis of the contribution of each pass-by noise source to the overall pass-by noise is an important issue for reduction of pass-by noise. A technical approach for predicting tailpipe noise is used to identify the contribution of tailpipe noise to the pass-by noise in this study. Simulation program with a time domain engine modeling program called 'WAVE' and wave propagation theory of moving noise source are employed. Since the Doppler phenomenon causes a frequency shift during a pass-by noise test, the Doppler correction and time delay effects are incorporated into the estimation of tailpipe noise. The developed program can furnish an in-depth understanding of the effect of tailpipe to pass-by noise.

In this paper, we present the degradation of focusing induced by velocity inhomogeneity in human tissue. For simulation, the fatty layer which is the major factor of degradation for its lower velocity, is modeled as a uniform velocity perturbation layer. And we simulate the degradation of resolution resulting from change of beam path due to refraction and the time delay due to velocity difference. We show that focusing error can be compensated for considering the velocity inhomogeneity only. The proposed compensation method can be operated in real time in the presently used digital focusing systems.

The method of the reducing duct noise can be classified by passive and active control techniques. However, passive control has a limited effect of noise reduction at low frequencies (below 500Hz) and is limited by the space. On the other hand, active control can overcome these passive control limitations. The active control technique mostly uses the Least-Mean-Square (LMS) algorithm, because the LMS algorithm can easily obtain the complex transfer function in real-time particularly when the Filtered-X LMS (FXLMS) algorithm is applied to an active noise control (ANC) system. However, the convergence performance of the LMS algorithm decreases slightly so it may delay the convergence time when the FXLMS algorithm is applied to the active control of duct noise. Thus the Co-FXLMS algorithm was developed to improve the control performance in order to solve this problem. The Co-FXLMS algorithm is realized by using an estimate of the cross correlation between the adaptation error and the filtered input signal to control the step size. In this paper, the performance of the Co-FXLMS algorithm is presented in comparison with the FXLMS algorithm. Simulation results show that active noise control using Co-FXLMS is effective in reducing duct noise.

A distance relay has been widely used for transmission line protection. The distance relay detects a fault based on the calculated impedance i.e. the ratio of the voltage to the current measured from a current transformer (CT) and a coupling capacitor voltage transformer (CCVT), respectively. When a fault occurs and a CT saturates due to the magnitude of fault current, dc component, primary time constant, and the remanent flux of the iron core, the secondary current of a CT is distorted On the other hand, non-fundamental components generated during a fault can increase the error of a CCVT, particularly when a fault distance is short. The distortion of the current and voltage can cause mal-operation or the operating time delay of a distance relay. This paper describes the response of a distance relay considering the errors of a CT and a CCVT. The results indicate that the severe distortion of a CT and a CCVT have noticeable effect to a distance relay.

The water-in-fuel droplets were applied to investigate the effect of mixing ratio between water and decane, ambient temperature, droplet size and spacing between droplets on ignition and micro-explosion in a heated chamber with high temperature. The ignition temperature of droplet was found lower as the droplet size was increased and the contents of water was decreased. The life time of droplet, however, decreases as the contents of water increases due to the micro-explosion. The occurrence of micro-explosion also increases as the size of droplets and the ambient temperature increase. The flame spread speed gets faster as the contents of water and the number of suspender decreases.
