This report focusses on the planning and realization of an interdisciplinary local area network (LAN) for medical research at the University of Heidelberg. After a detailed requirements analysis, several networks were evaluated by means of a test installation, and a cost-performance analysis was carried out. At present, the LAN connects 45 (IBM-compatible) PCs, several heterogeneous mainframes (IBM, DEC and Siemens) and provides access to the public X.25 network and to wide-area networks for research (EARN, BITNET). The network supports application software that is frequently needed in medical research (word processing, statistics, graphics, literature databases and services, etc.). Compliance with existing “official” (e.g., IEEE 802.3) and “de facto” standards (e.g., PostScript) was considered to be extremely important for the selection of both hardware and software. Customized programs were developed to improve access control, user interface and on-line help. Wide acceptance of the LAN was achieved through extensive education and maintenance facilities, e.g., teaching courses, customized manuals and a hotline service. Since requirements of clinical routine differ substantially from medical research needs, two separate networks (with a gateway in between) are proposed as a solution to optimally satisfy the users’ demands.

Traditional transmission line tower grounding resistance measurements have many shortcomings, in order to make up the defects the model of transmission line tower with good conductor wires and multiple grounding leads was builded, and then the algorithm of tower grounding resistance on-line measurement was proposed. On this condition, a system based on this algorithm was designed and further analysis of the error during data processing was conducted. At last, the MATLAB simulation indicates that the algorithm has a accuracy that meets the practical requirements.

Abstract. Pulau Laut is one of the outer islands in Republic of Indonesia and part of the international shipping lanes during past centuries. The evidence came in form of shipwrecks which also became archaeological sites. The purpose of this study is to determine the distribution of archaeological sites and its depth using Wenner configuration 2D geoelectric method which is achieved by using resistivitymeter multichanel S Field with three lines measurements. Data processing, analysis, and interpretation were performed using software RES2DINV. The results then obtained direction on line one southwest - Northeast, the vessel is allegedly at positions 21-24 m from the southwest, the value of resistivity is between 54, 3-124 Ωm with depth of 0-3 m subsurface. Line two is at the same direction with line one and the vessel is allegedly at positions 21-27 m from the southwest, a subsurface depth of 0-3 m and resistivity values range from 11.5 - 41.4 Ωm. Line three to the direction northwest - southeast is crosslined with track one and track two, allegedly the ship is at position 18-22 m from the northwest with a depth of 0 - 4 m above the ground and resistivity values between 56.7 - 205 Ωm. Abstrak. Pulau Laut merupakan salah satu pulau terdepan wilayah NKRI, merupakan jalur pelayaran internasional selama beradab-abad yang lampau. Terdapatnya situs-situs arkeologi kapal tengelam merupakan buktinya. Tujuan dari penelitian ini untuk menentukan sebaran situs arkeologi dan kedalamnnya berdasarkan metode geolistrik konfigurasi Wenner 2D yang menggunakan resistivitymeter multichannel S Field dengan tiga lintasan pengukuran. Proses pengolahan, analisis serta interpretasi data dilakukan dengan software Res2Dinv. Hasil proses, analisis dan interpretasi data, diperoleh pada lintasan satu dengan arah bentangan kabel barat daya – Timur laut, situs kapal diduga pada posisi 21 – 24 m dari arah barat daya, nilai resistivitas antar 54,3 – 124 Ωm dengan kedalaman 0 – 3 m dari atas permukaan tanah. Lintasan dua dengan arah bentangan kabel yang sama dengan lintasan satu, posisi 21 – 27 m dari arah barat daya,kedalaman 0 – 3 m dari atas permukaan tanah dan rentangan nilai resistivitas 11,5 – 41,4 Ωm diduga terdapat situs kapal. Lintasan tiga dengan arah bentangan kabel barat laut – tenggara merupakan lintasan yang memotong (crossline) lintasan satu dan lintasan dua, diduga keberadaan situs kapal pada posisi 18 – 22 m dari arah barat laut dengan kedalaman 0 – 4 m dari atas permukaan tanah dan nilai resistivitas antara 56,7 – 205 Ωm.

Modifications to the Parkes interferometer are described which allow synthesis observations to be made while still retaining the flexibility of frequent baseline changes. Details are given of the receiver with a phase stabilizing device and its performance, on-line computer control, and data processing. Preliminary observations with a resolution of l' of the two sources PKS 2152-69 and 2356-61 and possible optical identifications are discussed briefly.
