In this paper, we present the results from a high horizontal resolution numerical simulation of the northwestern Mediterranean using a z-level, non-hydrostatic, primitive equation ocean model (DieCAST). The high resolution allows an accurate representation of the submarine canyons that presides in the region. The model is one-way coupled to a large scale model of the Mediterranean Sea through o...

In contrast to the conventional send/receive model, the one-way communication model—using Put and Synch—allows the decoupling of message transmission from synchronization. This opens up new opportunities not only to further optimize communication but also to reduce synchronization overhead. In this paper, we present a general technique which uses a global dataflow framework to optimize communic...

A schema mapping is a high-level specification in which the relationship between two database schemas is described. In data exchange, schema mappings are one-way mappings that describe which data can be brought from source data to target data. Therefore, given a source instance and a mapping, there might be more than one valid target instance. This fact causes many problems in query answering o...

The IETF has developed a one-way packet loss metric that measures the loss rate on a Poisson and Periodic probe streams between two hosts. However, the impact of packet loss on applications is, in general, sensitive not just to the average loss rate but also to the way in which packet losses are distributed in loss episodes (i.e., maximal sets of consecutively lost probe packets). This document...

The Internet, an important modern means of obtaining information and establishing communication with others, has become an increasingly essential element of human life. Although Internet use makes life easier, it can become problematic in the event of non-functional use. Debate and research into whether Internet addiction is a cause or an effect are continuing. This study investigates problemat...

The main purpose of this study is to investigate the validity and reliability of the Interaction Anxiousness Scale and to examine whether there are gender and social status differences among Turkish adolescents. The Interaction Anxiousness Scale, is a 21-item Likert-type scale, was distributed to several high schools and data obtained from 622 students was examined. Cronbach’s Alpha reliability...

As against the conventional send/receive model, the one-way communication is a new paradigm which decouples message transmission and synchronization. This opens up new opportunities not only to further optimize communication but also to minimize synchronization costs. In this paper, we present a generalized technique which makes use of global dataflow framework to optimize communication and syn...

In this paper, we present a distinguisher for the permutation of SIMD-512 with complexity 2. We extend the attack to a distinguisher for the compression function with complexity 2. The attack is based on the application of the boomerang attack for hash functions. Starting from the middle of the compression function we use techniques from coding theory to search for two differential characterist...

At CRYPTO 2008 Stam [8] conjectured that if an (m+s)-bit to s-bit compression function F makes r calls to a primitive f of n-bit input, then a collision for F can be obtained (with high probability) using r2 queries to f , which is sometimes less than the birthday bound. Steinberger [9] proved Stam’s conjecture up to a constant multiplicative factor for most cases in which r = 1 and for certain...
