In this paper we give an outline of recent algebraic results concerning theories and models of the untyped lambda calculus.

the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

This paper investigates politically connected firms in Germany. With the introduction of a new transparency law in 2007, information on additional income sources for all members of the German parliament became publicly available. We find that members of the conservative party (CDU/CSU) and the liberal party (FDP) are more likely to work for firms than members of left-wing parties (SPD and The L...

This paper presents a control of active suspension for quarter car model with two degree of freedom by using H∞ method. Absolute velocity of car body is measured for feedback. The system parameter variations are treated with multiplicative uncertainty model. Simulation results show that the H∞controller provides good trade-off between ride quality, suspension packaging and road holding constrai...

If D is C+ or D , then we prove that H1(D) is a Hermite regular coherent ring of weak global dimension 2 (the coherence was already proved in [4]). We show: there is a one-to-one equivalence between systems de ned by matrices with entries in H1(D) and coherent H1(D)-modules, coherent H1(D)-modules are stable by elementary algebraic operations, and thus, we can characterize the algebraic propert...

We present detailed theoretical studies of the H-bonded complexes formed from interaction between 5-fluorouracil and various six-membered cyclic nitrosamine compounds. In this study, an investigation on intermolecular interactions in X-NU (X = CH2, SiH2,BH, AlH, NH, PH, O and S) complexes is carried out using density functional theory. The calculations are conducted on B3L...

The theory of H-spaces and the H control theory on finite dimensional spaces have been summarized by C. G. Hu and C. C. Yang (Hu and Yang, 1992), and B. A. Francis and J. C. Doyle ((Francis, 1987), (Francis and Doyle, 1987)) respectively. In 1993, B. V. Keulen extended the H control theory on finite dimensional spaces to range in the infinite dimensional Hilbert space (Keulen, 1993). In 2002, C...
