This study presents a bivariate extension of the goodness-of-fit measure for regional frequency distributions developed by Hosking and Wallis [1993] for use with the method of L-moments. Utilising the approximate joint normal distribution of the regional L-skewness and L-kurtosis, a graphical representation of the confidence region on the L-moment diagram can be constructed as an ellipsoid. Candidate distributions can then be accepted where the corresponding the oretical relationship between the L-skewness and L-kurtosis intersects the confidence region, and the chosen distribution would be the one that minimises the Mahalanobis distance measure. Based on a set of Monte Carlo simulations it is demonstrated that the new bivariate measure generally selects the true population distribution more frequently than the original method. An R-code implementation of the method is available for download free-of-charge from the GitHub code depository and will be demonstrated on a case study of annual maximum series of peak flow data from a homogeneous region in Italy.

Company A should maintain myriad conversion tools for the purpose of making a geometric compilation of navigation maps. Company A is already using complex compilation tools, which are tailored to geographical areas and various GPS models. However, due to frequent requirement and personnel changes, there is an endless challenge for perfect tool configuration and multiple map consolidation. To solve this problem, Company A launched a process automation project using Graphviz, which is an open source workflow graph visualization software. Before implementation, they had to document their current map compilation processes and then match it with the applicable conversion tool. For effective representation of process controls, a new graphical process notation is designed, i.e. Y Block diagram. The authors will compare Y Block diagram with other process notations and explain why Y Block diagram is more useful for tool based business processes such as digital map generation processes.

The present study examines the role of the script used for the graphical representation of a brand name in creating brand meaning. The study results demonstrate that each script contributes to forming different aspects of the brand meaning in multi-script environments. However, the process of meaning transfer is also influenced by the context of the product category, which can impact some of the aspects of meaning related to norms and familiarity. Furthermore, the study indicates that if the brand meaning aligns with the product category schema, it positively impacts brand attitude. This study adds to the branding literature by introducing the script concept as a brand name characteristic and demonstrating its significant effect on brand meaning.

In the present work, a microelogated thermoelastic model based on Lord-Shulman (1967) and Green-Lindsay (1972) theories of thermoelasticity has been constructed. The governing equations for the simulated model are converted into two-dimensional case and made dimensionless for further simplification. Laplace and Hankel transforms followed by eigen value approach has been employed to solve the problem. The use of eigen value approach hasthe advantage of finding the solution of governing equationsin matrix form notations. This approach is straight forward and convenient for numerical computation and avoids the complicate nature of the problem. The components of displacement,stress and temperature distribution are obtained in the transformed domain. Numerical inversion techniques have been used to invert the resulting quantities in the physical domain. Graphical representation of the resulting quantities for describing the effect of microelongation are presented. A special case is also deduced from the present investigation. The problem find application in many engineering problems like thick-walled pressure vesselsuch as a nuclear containment vessel, a cylindricalroller etc.

This paper is concerned with the disturbances in a transversely isotropic new modified couple stress homogeneous thermoelastic rotating medium under the combined influence of Hall currents, magnetic fields, and mechanical sources represented by inclined loads. The application of Laplace and Fourier transform techniques are used for the derivation of analytical expressions for various physical quantities. As an application,the bounding surface is subjected to uniformly and linearly distributed force (mechanical force). Present model contains length scale parameters that can capture the size effects. Numerical inversion techniques has been used to provide insights into the system's behavior in the physical domain. The graphical representation of numerical simulated results has been presented to emphasize the impact of rotation and inclined line loads on the system, enhancing our understanding of the studied phenomena. Further research can extend this study to investigate additional complexities and real-world applications.

This research deals with the study of two-dimensional deformation in transversely isotropic thermoelastic diffusion medium. This investigation integrates the effect of diffusion and thermal effects in transversely isotropic thermoelastic solids under inclined load. Inclined load is taken as linear combination of normal load and tangential load. Laplace and Fourier transformation techniques are employed to transform the physical domain and then transformed solutions are inverted with the aid of numerical inversion techniques. Concentrated and distributed load are considered to exemplify its utility. Graphical representation of variation in displacement, stresses, temperature and concentration distribution with distance is depicted by taking inclination at different angles. Some particular cases are studied.

Exponentially increasing biopathway data in recent years provide us with means to elucidate the large-scale modular organization of the cell. Given the existing information on metabolic and regulatory networks, inferring biopathway information through scientific reasoning or data mining of large scale array data or proteomics data get great attention. Naturally, there is a need for a user-friendly system allowing the user to combine large and diverse pathway data sets from different resources. We built a data warehouse - BIOWAY - for analyzing and visualizing biological pathways, by integrating and customizing resources. We have collected many different types of data in regards to pathway information, including metabolic pathway data from KEGG/LIGAND, signaling pathway data from BIND, and protein information data from SWISS-PROT. In addition to providing general data retrieval mechanism, a successful user interface should provide convenient visualization mechanism since biological pathway data is difficult to conceptualize without graphical representations. Still, the visual interface in the previous systems, at best, uses static images only for the specific categorized pathways. Thus, it is difficult to cope with more complex pathways. In the BIOWAY system, all the pathway data can be displayed in computer generated graphical networks, rather than manually drawn image data. Furthermore, it is designed in such a way that all the pathway maps can be expanded or shrinked, by introducing the concept of super node. A subtle graphic layout algorithm has been applied to best display the pathway data.

CVE(Collaborative Virtual Environment)는 물리적으로 함께 모이지 못하는 사람들이 서로 의논하고, 공동으로 일할 수 있는 가상공간의 공유된 장(場)을 말한다. CVE에서 참여자들은 가상적으로 그들이 존재할 수 있게 하는 사람의 형상을 닮은 체현(體現), 즉 아바타를 통해 대표된다. 그러나 현재 가상환경에서 볼 수 있는 대부분의 아바타들은 그 아바타의 행동과 사용자간에 일어나고 있는 대화 사이의 자연스러운 관계를 나타내지 못하고 있다. 사람과 사람간의 대화에 있어서 교환되는 정보의 65% 이상이 비언어적 기호에 의해 전달된다는 점을 감안할 때, 비언어적 커뮤니케이션 채널을 CVE 시스템의 아바타에서 제공하는 것은 매우 중요하다. 따라서 본 연구는 아바타 제스츄어 디자인에 적용될 수 있는 비언어커뮤니케이션의 전달양식을 도출하고 사람과 사람간의 커뮤니케이션 과정에서 발생하는 대표적인 신체언어들을 언어와의 관련성에 따라 유형을 분류한 후 머리에서 발까지 신체부위별로 흔히 사용되는 동작과 그에 부합하는 언어표현들을 정리하여 제시하는 방법으로 CVE에서 사용자들이 적절한 커뮤니케이션 활동을 할 수 있도록 지원하는 아바타의 동작표현을 제안하고 있다.

최근 몇 십년간 이산사건시스템명세(DEVS) 형식론은 이산사건시스템을 모듈러하고 계층적으로 모델링할 수 있는 잘 정의된 의미론을 제공하여 왔다. 그럼에도 불구하고 실용 엔지니어들은 실세계의 시스템을 모델링에 적용하는데 어려움을 겪기도 하는데 이는 DEVS가 많은 상태와 사건들을 구조화되지 않은 형태로 명세해야 하는 것 때문이다. 본 논문은 집합 이론을 바탕으로 그러한 사건 및 상태집합들을 구조화된 형태로 표현하는 Structured DEVS 형식론과 이와 연관된 DEVS 다이어그램을 제안하고자 한다. 위상, 변수, 포트 등의 개념을 사용하여 집합들을 명세한 구조적 DEVS 형식론은 원래의 DEVS 형식론과 동등함을 증명하였다. DEVS 다이어그램을 이용하여 구조적 DEVS 형식론으로 표현된 예시 모델이 쉽게 객체지향 시뮬레이션 환경에서 구현될 수 있음을 보임으로써 제안된 형식론이 효과적임을 보였다.
