Benchmarking Apache Arrow Flight - A wire-speed protocol for data transfer, querying and microservices

Moving structured data between different big data frameworks and/or data warehouses/storage systems often cause significant overhead. Most of the time more than 80% of the total time spent in accessing data is elapsed in serialization/de-serialization step. Columnar data formats are gaining popularity in both analytics and transactional...

Steps towards 3D Cadastre and ISO 19152 (LADM) in Israel

This paper contains the results of the 3D Cadastre and LADM (Land Administration Domain Model) investigations in context of possible future renewal of the Cadastral database at the Survey of Israel. The two topics of 3D Cadastres and LADM are highly related and therefore this paper covers both aspects. After recapturing the past 3D cadastre...

Parallel recording with optical waveguide array

We present an analysis of the reading capability of a novel optical pickup consisting of a single-mode and a multi-mode rectangular waveguide. According to the simulations, if one has prior information about the structure of the disk, superresolution readout could be achieved. The proposed system has the advantage to be compact and should be...

3D-gis in networking environments

In this paper, we present a data model for 3D geometry and topology in a 3D-GIS. This data model includes the concept of several views for the same feature, which enables several presentations of the same data. Together with a spatial index, this view-concept will be used to visualize the 3D-GIS data in a distributed networking environment. The...

Network interface unit "Artemis product dissemination by E-mail"

ARTEMIS (Africa Real-Time Environmental Monitoring Information System) is used by FAQ (Food and Agriculture Organisation of the United Nations) to support both its internal prograimnes on early warning and food security and desert locust control as well as developing countries in Africa by processing image information originating from the...

SPINE: Software platform for computer supported co-operative work in heterogenous computer and software environments

In development of High Performance Computing and Networking (HPCN) for simulation applications several targets have to be realized. It is recpiired to maximize not only computational speed but also to maximize applicability in engineering environments. For applications in which HPCN-based simulations are economically and technically necessary...
