To each computable enumerable (c.e.) set A with a particular enumeration {As}s∈ω, there is associated a settling function mA(x), where mA(x) is the last stage when a number less than or equal to x was enumerated into A. One c.e. set A is settling time dominated by another set B (B >st A) if for every computable function f , for all but finitely many x, mB(x) > f(mA(x)). This settling-time order...

A dilute suspension of uniform, non-Brownian spheres settles slowly in a viscous solvent. The initially well-mixed system showing Poisson or random occupancy statistics evolves to a system having reduced number fluctuations, but otherwise appearing random. The reduced number fluctuations are consistent with recent measurements of velocity fluctuations in settling suspensions. These experimental...

The semantics introduced in [3] is extended to all topological spaces.

the effluent quality of a sewage treatment plant using activated sludge process and finally secondary treatment depends on the flocculation efficiency and settling of the flocs. the survey of various treatment processes in water and wastewater treatment shows that temperature and ph are the important factors affecting efficiency of flocculation and settling properties. this study was performed ...

Elevated deer densities have led to reports of forest regeneration failure and ecological damage. However, there is growing evidence that the biophysical conditions of a forest thatmake it attractive to deermay be a contributing factor in determining browsing levels. Thus, an understanding of settling stimulus—how attractive an area is to deer in terms of food-independent habitat requirements— ...

It is well known that timing jitter can degrade the bit error rate (BER) of receivers that recover clock information from the input data. However, timing jitter can also result in an indefinite increase in the settling time of clock recovery circuits at the receivers, particularly in low swing mesochronous systems. Mesochronous clock retiming circuits are required in repeaterless low swing on-c...

Aerobic granulation is a promising biotechnology for wastewater treatment. The formation and development of granules and the pollutant removal are closely associated with hydrodynamic shear force, settling time and volume exchange ratio (VER), which are proved to be the selection pressures. Three different values of shear force (2, 3 and 4 cm/s), settling time (3, 5 and 10 min) and VER (25, 50 ...

A field experiment was conducted to quantify settling velocities, aggregate states, and flocculation within a hopper dredge plume. Particular interest was in determining the abundance of dense, bed aggregates suspended from the consolidated bed during dredging. A suspended sediment plume from the hopper dredge Essayons was sampled for a period of 90 min after dredging. Settling velocities and s...

OBJECTIVES To investigate whether sleep disturbances previously found to characterise high risk infants: (a) persist into childhood; (b) are influenced by early maternal settling strategies and (c) predict cognitive and emotional/behavioural functioning. METHODS Mothers experiencing high and low levels of psychosocial adversity (risk) were recruited antenatally and longitudinally assessed wit...
