According to balance theory (Heider, 1958), when 2 coworkers develop different levels of leader-member exchange (LMX) relationships with their supervisor, a triadic relational imbalance will arise among the 3 parties that may result in hostile sentiments and poor social interactions between them. This study examines the consequences and psychological processes of (dis)similar levels of LMX on t...

Conceptualizing, visualizing, analyzing, reasoning about and implementing Dynamic Interactive Systems (DISs) are difficult and error-prone activities. To conceptualize and reason about the sorts of properties expected of any DIS, a formal framework that most naturally facilitates conceptualization and modelling of DISs is essential. In this paper we propose and explain why extending the Equival...

In order to distribute new multimedia applications on a high scale, the mostly used and analyzed wide area networks (WAN) are the Internet on one side and ATM based networks on the other side. One of the current research activities in the networking area consists in trying to federate the Internet new mechanisms / protocols (IP new Generation : IPnG) and the ATM ones, in order to allow applicat...

Maintaining coherence between the independent views of multiple participants at distributed locations is essential in an Embedded Simulation environment. Currently, the Distributed Interactive Simulation (DIS) protocol maintains coherence by broadcasting the entity state streams from each simulation station. In this dissertation, a novel alternative to DIS that replaces the transmitting sources...

The QCD dipole picture allows to build an unified theoretical description -based on BFKL dynamicsof the total and diffractive nucleon structure functions. We use a four parameter fit to describe the 1994 H1 proton structure function F2 data in the low x, moderate Q2 range. Without any additional parameter, the gluon density and the longitudinal structure functions are predicted. The diffractive...

Data integration consists in providing a uniform access to a set of heterogeneous sources through a common representation called global schema. In this paper we present DIS@DIS, a data integration system that adopts innovative techniques for query answering in a complex integration environment. In particular, DIS@DIS is able to deal with integrity constraints, which are used to enhance the expr...

This paper presents the SEEDS simulation environment for the evaluation of distributed traffic control systems. Starting with an overview of the general simulator architecture, the software modules and the derived hardware architecture of the simulation environment are described with respect to performance requirements. The communication architecture of the SEEDS simulator is based on the OMG’s...

The pursuit of the “train as we fight, fight as we train” goal continues with the third Coalition Readiness Management System (CReaMS) training exercise conducted during the period 9 – 12 September, 2003. Known as Virtual Coalition Readiness (VCR), this exercise was based on a scenario of a coalition maritime battle group assisting a local ally to defend offshore island regions against an aggre...
