3d Scanners (United Kingdom)

Nowadays, the usages of Terrestrial Laser Scanner (TLS) have been practise widely use in the mapping and modelling of varies field. This is because of the advantages that TLS provided; such as speed in data collecting, high accuracy as well as saving time. One of the main technologies of TLS is by producing a 3 Dimension (3D) that can be analysed from a surface of an object and form of the real world. TLS is practically use in Civil Engineering or Geographic Information System (GIS) for objects modelling and reviewing tunnels volume whereas for Archaeology it be used by maintaining the details of cultural heritage. However, TLS has not been analysed in 3D for the parking area. The main purpose of this study took place is to prove the ability of TLS in producing and analysing into 3D modelling for this particular area. The study has been done at the parking lot of the Department of Survey and Mapping (JUPEM), Kuala Lumpur. The methods that been used for this study are by using a 3D Terrestrial Laser scanner (TLS), Leica Scan Station C10, image point cloud registration, 3D modelling, Cyclone software, parametric modelling 3D and Autodesk Revit. From this study, it helps the JUPEM department in producing 3D detailing plan as well as speed up the outcome of retrieving details for an object and can be presented in tangible form without physically going to the particular area or a site. Therefore, with this introduction of 3D modelling technology towards the relevant fields, it can help others in solving problems for internal infrastructure for buildings and structures.

In modern cryptosystems, there are many well-proven often used constructions, such as operations in binary fields. In this paper method of algorithm construction for modular reduction by fixed irreducible polynomial (trinomial or pentanomial) was proposed. This method applying allows to get a high performance algorithm of modular reduction for specified fixed polynomial and target platform while cryptosystems develop, for example elliptic curve cryptosystem.
