Thin films ofCo-W, 300-500 A thick, were electrodeposited at various compositions under a wide range ofplattng conditions. The saturation magnetization, coercivity, and squareness ratio of the films were derived from the parallel (in-plane) and perpendicular hysteresis loops, measured by using a vibrating sample magnetometer. The magnetic properties of the films are strongly related to their mi...

This paper reports the results of tests on Indiana gravels ranging from good to poor in field performance in Portland cement concrete. The gravels were separated by heavy liquid flotation into various specific gravity ranges. The gravel fractions thus obtained were tested to deter­ mine absorption, specific gravity, degree of saturation, lithologic compo­ sition and durability in air entrained ...

Brushite (CaHPO(4).2H(2)O) was considered to govern the formation of renal calculus of calcium phosphate origin. The degree of saturation of urine with respect to this phase was therefore calculated. This value was obtained from the ratio of the activity product of Ca(++) and HPO(4) (m) (K(sp)) before and after incubation of urine with brushite. The errors in the calculation of K(sp) were large...

This paper presents a Greedy-Least Saturation Degree (G-LSD) heuristic (which is an adaptation of the least saturation degree heuristic) to solve a real-world examination timetabling problem at the University Kebangsaan, Malaysia. We utilise a new objective function that was proposed in our previous work to evaluate the quality of the timetable. The objective function considers both timeslots a...

The sipunculid, Themiste pyroides is found intertidally to subtidally from Southern British Colombia to Northern Mexico. An avid burrower in rock nooks and crevices, this worm is prone to hypoxic environments, particularly during low tide. T. pyroides uses the oxygen-transport protein, hemerythrin to transport oxygen from the tentacles to the vascular system and into the coelom. Because hemeryt...

An iterative geostatistical inverse approach is developed to estimate conditional effective unsaturated hydraulic conductivity parameters, soil-water pressure head, and degree of saturation in heterogeneous vadose zones. This approach is similar to the classical cokriging technique, and it uses a linear estimator that depends on covariances and cross covariances of unsaturated hydraulic paramet...

In this paper, we investigate the channel assignment problem, that is, the problem of assigning channels (codes) to the cells of a cellular radio network so as to avoid interference and minimize the number of channels used. The problem is formulated as a generalization of the graph coloring problem. We consider the saturation degree heuristic, first proposed as a technique for solving the graph...

In this paper a general quantum mechanical treatment of photodissociation and fluorescence from the fragments in the case of direct dissociation as well as in the case of photo-predissociation is presented. This formulation takes into consideration all the possible coherence effects coming from quantum interference between photodissociation amplitudes to different magnetic sublevels of the frag...

This paper presents the ndings of a study devoted to a comparison of the eeective-ness of Linear Quadratic Regulator (LQR) and H 1 control for structures subjected to earthquake loadings. Research in the eld of active structural control has received much attention over the past few years, with the majority of eeorts focusing on formulation and application of the LQR-based control algorithms. Be...

We investigate saturation effects in susceptible-infected-susceptible models of the spread of epidemics in heterogeneous populations. The structure of interactions in the population is represented by networks with connectivity distribution P(k), including scale-free (SF) networks with power law distributions P(k) approximately k(-gamma). Considering cases where the transmission of infection bet...
