The inverse boundary value problem for the steady state heat equation with convection term is considered in a simply connected bounded domain with smooth boundary. Taking the Dirichlet to Neumann map which maps the temperature on the boundary to the that flux on the boundary as an observation data, the global uniqueness for identifying the convection term from the Dirichlet to Neumann map is proved.

Unidimensional construct of conspicuous consumption which focuses on the ostentation of the economic assets are limited in describing today's consumers. We propose that both ostentation of social status and demonstration of uniqueness through overt consumption should be considered in the realm of conspicuous consumption. This research aims to examine the two dimensions of conspicuous consumption tendencies and their impact on new product adoption intention, which is mediated through the perceived value of the new products. This research empirically validates the theoretical conjecture by conducting an online survey (N=272). Our empirical findings reveal that ostentation of social status influences new product adoption intention both directly and indirectly through perceived social value, while demonstration of uniqueness improves new product adoption intention only indirectly through perceived utilitarian and hedonic value. This research identifies the ostentation of social status and demonstration of uniqueness as two dimensions of conspicuous consumption and refines scales to measure them. In addition, this research identifies conspicuous consumption as a driver of new product adoption intention and recognizes the mediating role of perceived value.

This manuscript addressed, the existence and uniqueness result for random impulsive stochastic functional differential equations with finite time delays. The study of random impulsive stochastic system is a new area of research. We interpret the meaning of a stochastic derivative and how it differs from the classical derivative. We prove the existence and uniqueness of mild solutions to the equations by using the successive approximation method. We conclude the article with some interesting future extension. This work extends the work of [18, 12, 20]. Finally, an example is given to illustrate the theoretical result.

In this paper, we explore the uniqueness property between the transcendental meromorphic functions and differential polynomial. With the notion of weighted sharing, we generalised the many previous results on uniqueness property. Here we discussed the uniqueness of [P(f)(αf^m + β)^s]^(k) - η(z) and [P(g)(αg^m + β)^s]^(k) - η(z). Meanwhile, we generalised the result of Harina P. waghamore and Rajeshwari S[1].

Consumers want to express their original unique personality, and even are willing to endure high expenses in order to do this. One noticeable strategy in the market, used by companies to suit for this consumer sentiment, is that of employing limited edition marketing and limited free gifts. This study investigated the effects of limited free gifts on consumer response. Specifically, the present study examined how the need for uniqueness moderated the effects of limited free gifts on brand commitment and attitudes. The online survey method was used to gather the data and a total of 224 data were used to analyze data. The results of the research were as follows. The findings revealed four dimensions of limited free gifts: scarcity/specialty, not for sale, complementarity, and risk. Complementarity positively affected brand commitment, while all four dimensions of limited free gifts positively influenced brand attitude. In addition, the need for uniqueness was proven to be the strongest variable which positively influenced brand commitment and attitudes. Also, when the need for uniqueness was applied as a moderating variable, depending on the levels of the need for uniqueness, the effects of riskiness on the consumer's response were shown to be different. The findings of this study infer various academic and practical applications.

내용기반 비디오 정합은 원본의 클립에서 특징(signature)을 구한 후 복사본의 특징과 비교하여 유사도를 측정한다. 특히 정확한 위치의 프레임을 정합하는 것은 매우 중요하며 원본과 복사본의 프레임율, 잡음, 해상도, 압축형식에 따라 정합 율이 달라질 수 있다. 비디오 특징 중 오디널(ordinal) 특징은 일반적으로 우수한 정합특징을 나타내고 있으나 비디오 특징의 구별 능력을 나타내는 유일성 실험(uniqueness test)과 잡음에 대한 내성을 나타내는 강건성 실험(robustness test)이 중요한 요소로 고려되지 않았다. Hua등은 유일성 실험에서 해상도, 압축형식 등을 고려하였지만 강건성 실험에서 영상에 잡음을 첨가하는 대신 압축 형식이 변환된 영상을 사용하였다. 본 논문에서는 오디널 특정의 유일성 분석과 함께 실질적인 잡음 모텔을 도입하여 오디널 특징의 강건성 실험 방법을 제안하고 성능을 분석하였다.

This paper is concerned with the optimality conditions for optimal control problem of Belousov-Zhabotinskii reaction model. That is, we obtain the optimality conditions by showing the differentiability of the solution with respect to the control. We also show the uniqueness of the optimal control.
