This study is to develope the quantitative risk assessment program for consequence analysis of fire and explosion (PML-Chem), which is applicable to the chemical plants. The advantages of PML-Chem is easy to use and acquire results. Especially, PML-Chem was embedded real weather condition database for major chemical plants in ${\bigcirc}{\bigcirc}$ complex in country. Also, reliability of PML-Chem was verified through comparing PML-Chem with PHAST-Professional which is already commercial.

This paper proposes an empty constituent, a silent beat, to express long duration of stressed syllable in the word final position and rhythmic correspondence in English. This empty constituent has an important consequence. It helps reveal one of the characteristics English feet have: they must be non-final in nouns as well as in verbs. In addition, the silent beats overcome the shortcomings of empty constituents proposed previously, namely null vowels (Burzio 1994) and invisible suffixes (Hammond 1999).

A new class of data transformation matri is introduced for estimation of angles of arrivals by the rank reduction of multiple wideband sources. The proposed unitary focusing matri minimizes the average of the squared norm of focusing error over the angles of interest without a priori knowledge of source locations. The merit that result as a consequence is a lower resolution threshold. These matrices can be applied to the case of the multigroup sources. Simulations and the comparison of statistical performance are compared with the algorithms (especially, spatial resampling method) which does not require the pre-estimation.

A consequence of global trade liberalization is that domestic regulatory policies have become a focal point for efforts to reduce the costs of engaging in cross-border production and exchange. This article discusses the general challenges of reducing trade frictions created by regulatory differences, focusing specifically on the role trade agreements might play in addressing regulatory spillovers. A case is made for a greater focus on plurilateral cooperation under the umbrella of the WTO.

Some results on inheritance of operator semi-selfdecomposability and its decreasing subclass property from subordinator to subordinated in subordination of a L$\acute{e}$evy process are given. A main result is an extension of results of [5] to semi-selfdecomposable subordinator. Its consequence is discussed.

Due to improvements in emergency resuscitation provided by rescue teams, more trauma victims who could have died due to sudden heart failure at the scene are brought to the hospital following resuscitation. Most of these patients present with major organ injuries and hypovolemic shock at the time of trauma. However, head trauma associated with sudden heart arrest is rare. Here, we report a case of ring fracture with pontomedullary laceration that led to sudden heart arrest.

In this paper, we propose the Chaos Fuzzy controller to analyze the chaotic character of time series obtained from the specific plant and to predict the short-term for power consumption of the plant using the Fuzzy controller. We compared the predicted data with the active ones and checked the error generated by them after we time series of supplied power to the proposed controller. As a result of the simulation, we obtained a admirable consequence that the proposed controller can be advanced through various and accurate data acquisition, and continuous analysis of the resident and industrial environment.

This work concerns estimating a regression function, which is not linear, using aggregate data. In much of the empirical research, data are aggregated for various reasons before statistical analysis. In a traditional parametric approach, a linear estimation of the non-linear function with aggregate data can result in unstable estimators of the parameters. More serious consequence is the bias in the estimation of the non-linear function. The approach we employ is the kernel regression smoothing. We describe the conditions when the aggregate data can be used to estimate the regression function efficiently. Numerical examples will illustrate our findings.

In this paper, we obtain an explicit formula of the Laplace transform of the forward recurrence time at finite time t > 0 in an alternating renewal process, by adopting a Markovian approach. As a consequence, we obtain the first two moments of the forward recurrence time.

The need of UPS (Uninterruptible Power Sup-ply) system is dramatically increasing with the increased use of computers, telecommunica-tion system, building automation system, and office automation system in office buildings. The consequence of the power failure is very disas trous in intelligent office buil-dings. Thus, the nucessity of large scale UPS system with generations of large scale UPS system with generator is increasing. In this study, the configurations of large scale UPS system are reviewed and analyzed. The design guide and technical considerations of high reliability system are presented.
