Agent-Based Modelling is gaining wider acceptance as a paradigm for social research. However, it still presents limitations in the management of the process to generate the simulations from the initial conceptual models. This makes it difficult to reuse the knowledge from available models and to adapt it to different hypotheses. This paper proposes the use of metamodels in order to define expli...

In the title complex, [Ni(C(22)H(16)Br(2)N(2)O(4))], the Ni(II) ion is coordinated by two N atoms and two O atoms of a tetra-dentate Schiff base ligand, forming a slightly distorted square-planar coordination environment. The dihedral angle between the two bromo-substituted benzene rings is 10.1 (3)°.

ÐWe present a simple paradigm for fitting models, parametric and nonparametric, to noisy data, which resolves some of the problems associated with classical MSE algorithms. This is done by considering each point on the model as a possible source for each data point. The paradigm can be used to solve problems which are ill-posed in the classical MSE approach, such as fitting a segment (as oppose...

4 Social problems have figured prominently in social change over the last ten years in the lands of the former Soviet Union. Although there have been many expert interpretations of these social problems, and many assessments of how different nationalities and classes interpret these problems, I address the spatial articulation of identity formation and social problems. Drawing upon 36 focus gro...

Apathy is a common neurobehavioral feature in a variety of neuropsychiatric disorders. Apathy is often interpreted as a sign of deppression or as a nonspecific symptom of other medical conditions. However, recent research indicates that the essential meaning of apathy is lack of motivation. This article presents a frame work for the classification and differential diagnosis of apathy and addres...

A measurement of the integrated luminosity at the ep collider HERA is presented, exploiting the elastic QED Compton process ep → eγp. The electron and the photon are detected in the backward calorimeter of the H1 experiment. The integrated luminosity of the data recorded in 2003 to 2007 is determined with a precision of 2.3%. The measurement is found to be compatible with the corresponding resu...

The reaction γp → ωp (ω → π+π−π0 and π0 → γγ) has been studied in ep interactions using the ZEUS detector at photon-proton centre-of-mass energies between 70 and 90GeV and |t| < 0.6GeV, where t is the squared four momentum transferred at the proton vertex. The elastic ω photoproduction cross section has been measured to be σγp→ωp = 1.21 ± 0.12 ± 0.23μb. The differential cross section dσγp→ωp/d|...

The expanding use of ubiquitous computing has created a significant demand on existing network infrastructures. The demands of voice, video, and data on the same medium require a quality of service (QoS) at a level acceptable to users. Many network providers simply scale their networks to increase bandwidth and hardware to deal with the increasing demands. However, a network may still reach its...
