The acid neutralization capacity of a cement/waste product is important because the integrity of the monolithic matrix and contaminant precipitation are dependent on the maintenance of alkaline conditions. A 1/8 fractional ...

A 3-D FIR frustum filter having sparse coefficients is proposed for enhancing broadband plane waves received by uniform aperture arrays. Motivated by the design technique of 1-D interpolated FIR filters, the proposed ...

Sri Lanka's dry zone is studded with nearly 12,500 small tanks built by ancient kings to store rain water for irrigation purposes. Most of them are called minor tanks which cater to land extents less than 80 ha.. Farmers--^nder ...

dentifying drought-affected regions is usually done using ground based data collection such as rainfall or field V\veys. However in data scarce regions or of large spatial extent, such assessment is difficult and time ...

Use of reclaimed rubber as a component of a blend with virgin rubber or as a replacement for the virgin material in most rubber applications, especially in tyre components, has increased in the recent past. This is due ...

Since partonomy knowledge is an important component of human cognition, we propose a point-set-based region (PSBR) model to approximate areal objects, especially vague areal objects. Two major properties of this model are ...

Techniques for modelling urban microclimates and urban block surfaces temperatures are desired by urban planners and architects for strategic urban designs at the early design stages. This paper introduces a simplified ...

The potential of natural ventilation and cooling due to stack effects was investigated for large spaces with high ceilings. Different opening area ratios with respect to floor area were studied. Parameters of stack effects ...

In a developing Country like Sri Lanka, it is very important to plan and manage its land development programmes to attract investments to develop land resources. In this context special emphasis should be given to urban ...

The global doctor-patient ratio is 17 per 1000 population, however, it is 1.23 per 1000 population in Sri Lanka [1]. As it is far behind the expected numbers, the Sri Lankan public health sector is facing challenges in ...
