Digital watermarking is a solution to the problem of copyright protection and authentication of multimedia data while working in a networked environment. We propose a robust quantization-based image watermarking scheme, called the gradient direction watermarking (GDWM), and based on the uniform quantization of the direction of gradient vectors. In GDWM, the watermark bits are embedded by quanti...

There are many approaches to proving the correctness of application-layer protocols that are layered on secure transport protocols, such as TLS. One popular approach is verification by abstraction, in which the correctness of the application-layer protocol is proven under the assumption that the transport layer satisfies certain properties. Following this approach, we adapt the strand spaces mo...

This paper develops a factor proportions driven monopolistic competition model of trade to examine how home-market e¤ects (HME) vary across countries and industries. I extend the multi-sector framework of Hanson and Xiang (AER 2004) to a two factor case where …xed cost of starting a business is more capital intensive than the marginal cost. Countries with di¤erent factor endowments have di¤eren...

Institutional trust is necessary for inter-organizational relationships in e-commerce. Two types of institutional trust are herein proposed (a) third-party institution-based trust, which deals with intermediary-driven structures, and (b) bilateral institutionalized trust, which deals with dyadic inter-organizational processes. We examine how these two types of institutional trust develop throug...

splenogonadal fusion is a rare entity with approximately 150 reported cases until the year 2005. the entity is a rare congenital anomaly in which there is fusion of splenic and gonadal anlagen or mesonephric derivatives. splenogonadal fusion has two continuous and discontinuous types. about ten cases have been reported to be associated with bilateral cryptorchidism in literature. very few cases...
