This paper proposes a pitch-control technique for grid-connected wind turbines in a small power system with low sywtem inertia. Wind turbines in such a power system give rise to poor quality of power and low system ...
In Sri Lanka at present, the mining of clay for the production of bricks and roof tiles is mechanized. The result of mechanized mining is deep pits left along river basins. These pits get filled with water during the wet ...
A simplified model for total project cost is developed in this paper to meet the numerous requests from decision makers for a model that can be used to estimate the total project cost from the estimated cash flows and, ...
A theoretical approach is presented for contingency allocation and management in building projects using the quantification of uncertainty of project cost. The uncertainty of input items to a bill of quantities, namely, ...
This paper develops a theoretical basis for three issues that are important in the quantification and management of uncertainty in activity duration networks. Firstly, the uncertainty in activity durations is quantified. ...
Field and petrological data, combined with major, trace and rare earth element analysis of mafic rocks that structurally underlie the Semail ophiolite in Saih Hatat, have led to their subdivision into five groups: (a) ...
Accidents in the process industry could be prevented or reduced by having good safety management measures. Such
preventive measures could be further improved through the experiences and lessons learnt from past ...
A figure of 0.075% by weight of sand was arrived at as a safe limit for allowable Cl ion content in offshore sand for OPC based
reinforced concrete. A 2 m high sand column was fabricated for checking the effects of natural ...
Long-term durability of highway structures is, and will for the forseeable future, be a major problem facing engineers. Movement of deleterious ionic species in solution through the cover region and the resulting corrosion ...
This paper investigates three major issues regarding the elicitation of expert knowledge for economic risk analysis: (1) recognition of some of the implicit assumptions and beliefs; (2) development of an approach to elicit ...
The standard form of contract plays a significant role in a construction project as it communicates the
procedures to be adopted in executing the project including the determination of the rights and obligations of
contracting ...
Knowledge is the fundamental resource that allows us to function intelligently.
Similarly, organizations typically use different types of knowledge to enhance their performance.
Commonsense knowledge that is not well ...
In order to minimize the environmental impacts caused by over exploitation of natural resources for the production of building material, the possibility of using cement stabilized rammed earth for load-bearing walls has ...
A computationally efficient pile element and a time-incremental finite element code are developed to model laterally loaded piles in ice/permafrost, by modelling the pile as a beam supported on a spring-dashpot system. A ...
High-density residential developments on outskirts of cities with a large number of detached multistorey
houses on small blocks of land are actively promoted as a solution to urban migration in
many countries. Such a ...
Michael Polanyi’s idea of tacit knowing and Martin Heidegger’s concept of pre-theoretical shared practice are presented as providing a strong rationale for the notion of practice based knowledge. Artificial Intelligence ...
Flat slab construction has proved efficient and large numbers have been built. Often the layout of columns is limited to rectangular grid owing to the scarcity of structural analysis tools validated by experimental evidence. ...
Durability indicators for six OPC concrete mixes were obtained from wick action testing on concrete cylinders placed in water and a sodium chloride solution of concentration similar to sea water. Although 49 weeks of ...
When an estimator prices a bill of quantities, s/he collects, generates and assembles data (estimating data) for the purpose of establishing the cost of constructing the project. The data generated could be used by the ...
The prime purpose of the Bill of Quantities (BQ) is to enable all contractors tendering for a contract to price on exactly the same information. Subsequent to this, it is widely used for post-tender work such as: material ...
