Conquering a technology is always important.
Owning it adds an arsenal to the might of the nation.
Hence, there is a …
Limestone constitutes the predominant raw material for manufacturing clinker, which in turn is an intermediate product to produce cement. But if the deposit is not homogenous and the coeffi cient of variation (COV) of the main inherent radicals in limestone is very high then the consistency in the quality parameters of the product varies and so on the process requirements thereby affecting productivity. In such cases the deposit has to be understood statistically and a proper geological model should be designed to best fi t our mine design parameters. This paper deals in detail how surpac leads in solving a similar problem…
SIRGAS (Sistema de Referencia Geocéntrico para las Américas) is a joint project of South, Central and North American countries in cooperation with some international institutions for the establishment and maintenance of a geocentric reference frame for practical and scientific use. A unique reference frame for the American continent was established by two extremely successful geodetic observation campaigns…
Rural development may be defined as structural changes in the socio-economic situation to achieve improved living standard of low-income population residing in rural areas and making the process of their development self sustained. It includes economic development with close integration among various sections and sectors; and economic growth specifically directed to the rural poor. In fact, it requires area based development…
In the 1970s, the US Department of Defense began GPS development as a military force enhancer. In 1983, President Reagan offered GPS civil services to the world, free of direct charges, as a result of the KAL007 disaster. This global offer sparked widespread civil use of GPS and significant investment in civil GPS technologies, to include GPS civil augmenting satellites (e.g. US Wide Area Augmentation System (WAAS), European…

The last issue detailed the celebrations that took place for the anniversary of the birth of Sir George Everest but what do we know of the man? His is a household name because of its link to the mountain but many who are not surveyors either (a) think it is a made-up name for the …
A nautical chart is a medium of information and tool for safe maritime navigation. It is the chief nautical instrument for ocean route planning and safe navigation. With the time not only the user’s requirements have increased, but also the advancement in the expertise in the field of nautical cartography has resulted in better product in the most useful way. With the advent of modern cartography, chart contents are stored in…
Many researchers and R&D laboratories in the world deal with the design of the software-based or experimental GNSS receivers using digital signal processing for work and experiments with received navigational signals. These concepts have one in common: the necessity of use of some analogue RF part before conversion of the signal to the digital domain. The problem of the RF front end design of the experimental or special purpose navigation receivers has to be solved. It is not an easy task as can be seen from many papers and conference contributions. The aim of this paper is analysis of the possibility of such GNSS RF front end design. We will discuss the following three main approaches
