Abstract. With thousands of years of glorious history and culture, China, which is the origin of Chinese civilization has also survived with a magnificent amount of stone cultural heritage. Stone monuments are one of the most important components of Chinese monuments and contain a wealth of historical information by themselves. Due to the fact that some stone monuments and stone architectural elements are often exposed to the natural environment, they are subject to physical, biological, chemical and human damage over a long period of time, which leads to the formation of various kinds of damages. Therefore, it is an important issue to extract and analysis the diseases information effectively. In this paper, we were going to examine these issues in the context of existing surveying and mapping techniques.

Abstract: One of the key for successing the Complete Systematic Land Registration Project/ PTSL is efficient surveying and mapping. The purpose of this study was to determine variations in cadastral Surveying and mapping techniques used in PTSL East Lombok Regency. The research used qualitative-descriptive method with interview techniques, documentation and direct observation at the research location. Population and sample are all officers whom related to surveying and mapping activities in East Lombok district land office. The result of this research are  1) there are variations in cadastral Surveying and mapping techniques of the East Lombok  District Land Office; 2) an efficient Surveying technique is to use satellite observation techniques using Geodetic Geo Fennel GPS RTK devices which are an average of 50 fields per day for settlements and rice fields; 3) factors that influence are the availability of tools, human resources (measuring and mapping officers), the community as the applicant and the village apparatus, the area of land, the arrangement of land, the form of land, tool batteries, radio transmitter signals, reference points and multipath. Keywords: Surveying, Mapping, PTSL, Efficient, GPS. Intisari: Salah satu kunci keberhasilan PTSL terdapat pada pengukuran dan pemetaannya. Maka perlu dilakukan pengukuran dan pemetaan yang efisien. Tujuan penelitian ini adalah untuk mengetahui variasi teknik-teknik pengukuran dan pemetaan kadastral yang digunakan pada PTSL Kabupaten Lombok Timur. Metode penelitian yang digunakan penulis yaitu metode deskriptif kualitatif dengan teknik wawancara, dokumentasi dan observasi langsung di lokasi penelitian. Populasi dan sampel yaitu semua petugas yang berkaitan dengan kegiatan pengukuran dan pemetaan di kantor pertanahan Kab. Lombok Timur. Dari penelitian yang sudah dilakukan didapatkan data bahwa 1) terdapat variasi teknik-teknik pengukuran dan pemetaan kadastral Kantor Pertanahan Kab. Lombok Timur yaitu, 3 teknik pengukuran dan 3 teknik pemetaan; 2) teknik pengukuran yang efisien adalah dengan menggunakan teknik pengamatan satelit menggunakan alat GPS RTK Geodetic Geo Fennel yaitu rata-rata 50 bidang perhari untuk pemukiman maupun persawahan; 3) faktor-faktor yang berpengaruh adalah ketersedian alat, sumber daya manusia (petugas ukur dan pemetaan), masyarakat sebagai pemohon dan perangkat desa, luas bidang tanah, penataan bidang tanah, bentuk bidang tanah, baterai alat, sinyal pemancar radio, titik referensi dan multipath.Kata Kunci: Pengukuran, Pemetaan, PTSL, Efisien, GPS.Abstract: One of the key for successing the Complete Systematic Land Registration Project/ PTSL is efficient surveying and mapping.

Focal atrial tachycardia (AT) is a relatively uncommon cause of supraventricular tachycardia, but when present is frequently difficult to treat medically. Atrial tachycardias tend to originate from anatomically determined atrial sites. The P-wave morphology on surface electrocardiogram (ECG) together with more sophisticated contemporary mapping techniques facilitates precise localisation and ablation of these ectopic foci. Catheter ablation of focal AT is associated with high long-term success and may be viewed as a primary treatment strategy in symptomatic patients.

Abstract This work presents advanced resistance mapping techniques based on Scanning Electron Microscopy (SEM) with nanoprobing systems and the related embedded electronics. Focus is placed on recent advances to reduce noise and increase speed, such as integration of dedicated in situ electronics into the nanoprobing platform, as well as an important transition from current-sensitive to voltagesensitive amplification. We show that it is now possible to record resistance maps with a resistance sensitivity in the 10W range, even when the total resistance of the mapped structures is in the range of 100W. A reference structure is used to illustrate the improved performance, and a lowresistance failure case is presented as an example of analysis made possible by these developments.
