An all-digital ΣΔ--frequency discriminator of arbitrary order

In this paper, we propose an all-digital frequency synthesizer architecture, based on an all-digital ΣΔ-frequency discriminator. The new all-digital synthesizer is compared to previously published work. The architecture of the ΣΔ-frequency discriminator is verified using behavioral simulation.

Moisture Conditions in Exterior Walls for Net Zero Energy Buildings in Cold Climate - Considering Future Climate

An important measure for climate change mitigation is reduction of energy use in buildings worldwide. To decrease the energy use of a building in a Nordic climate, increased thermal resistance of the building envelope is a suitable measure. Adding more insulation in combination with climate change may increase the risk of mold growth within the building envelope. This study evaluates hygrothermal

Latin America between the dismantling of the state and the rise of social mobilization. The complexity of rural development in North East Argentina

This paper presents some preliminary empirical reflexions about rural development in North East Argentina at the light of the recent socio-economic and political changes. The processes of decentralization that have taken place in the country during the decade of 1990 illustrate the complexity of rural development strategies at local level and the necessity to create policies to take into account t

ACTA & European Union perspectives

Abstract in UndeterminedProfessor Mylly suggests that the Lisbon Treaty opens a new avenue for the Commission when the internal legislative pathway becomes too complicated, demanding unanimity in decision-making. An alternative route would be to use the competence to enter into international agreements, where qualified majority is enough. The agreements may be phrased in such a way that they have

Sensitivity of system reliability to usage profile changes

Usage profiles and component reliability are two important factors in software system reliability estimation. To assess the sensitivity of a system’s reliability to the usage profile and to the reliability of its components, a Markov based system model is used. With the help of this model, the maximum sensitivity to one change or the statistical sensitivity to many independent changes can be estim

Human Postural Dynamics

The study of posture dynamics is important not only to understand disorders of impaired equilibrium and protective reactions to unexpected displacements of the human body, but also to the design of prosthesis and functional neuromuscular stimulation as aids to patients with impaired postural stability and locomotion. Coordinated control of the body segments is a complex aspect of motor behavior, o
