Produk dari pengukuran dan pemetaan batas bidang tanah adalah peta bidang tanah. Sebagai salah satu kegiatan dalam rangka pendaftaran tanah, peta bidang tanah bukan merupakan bukti dari kepemilikan tanah melainkan sertifikat lah produk akhir dari kegiatan pendaftaran tanah sebagai bukti kuat hak atas tanah. Peta bidang tanah merupakan media dasar untuk kedepannya karena memuat informasi tentang kebenaran dari batas-batasnya di lapangan, letak, luas atau adanya penguasaan pihak lain di lapangan. Global Positioning System (GPS) adalah sistem untuk menentukan letak di permukaan bumi dengan bantuan sinyal satelit. Sinyal ini diterima oleh alat penerima (receiver) di permukaan bumi dan diperloeh informasi berupa letak, arah dan waktu. Pengukuran Real-Time-Kinematik merupakan jenis pengukuran GPS Real-Time yang dimana hasilnya akan diketahui langsung tanpa adanya proses pengolahan data terlebih dahulu. Penelitian ini merupakan penelitian yang bersifat deskriptif yaitu menggambarkan bagaimanakah tahapan atau proses pengukuran dan pemetaan bidang tanah di Kantor Badan Pertanahan Nasional Kantor Wilayah Provinsi Jawa Barat dengan penelitian pengukuran dan pemetaan bidang tanah di Citayam Kabupaten Bogor Jawa Barat.;---The product from the measurement and mapping land parcel boundary is a map plot. As one of the activities in the context of land registration, maps plot is not an evidence of land ownership, however the certificates was the end product of the land registration as a strong evidence of land rights. Map plot is the basis for future media because it contains information about the correctness of its boundaries in the field, the location, extent or their mastery of others in the field. Global Positioning System (GPS) is a system to determine the location on the earth's surface with the help of satellite signals. This signal is received by a receiver on the surface of the earth and obtained the information such as location, direction and time. Measurement of Real-Time-Kinematic is a type of real-time GPS measurements which the result will be known directly without any processing of the data in advance. This research is a descriptive research that illustrates how the stage or the process of measuring and mapping land parcels in the National Land Agency Regional Office of West Java province with the research of measuring and mapping land parcels in Citayam Bogor regency, West Java

Cold spray Cr-coated Optimized ZIRLO claddings: an option for accident tolerant fuels

Accident tolerant fuel development has started with the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had being delayed for the last few decades. Climate change is an ever-growing public concern, and policies about greenhouse gas emissions are becoming more stringent both at the national and international level. Nuclear energy produces very low carbon emissions and the successful development of new accident tolerant materials might play a role in making this technology a viable solution to this global issue. Cr-coated zirconium claddings are one of the most promising candidates as near-term response to the need for accident tolerant materials. These coatings can be produced via a range of different technologies, but the two main designs being currently developed are obtained with physical vapour deposition or cold spray (CS) deposition. In cold spray, high pressure gas is fed through a nozzle together with Cr powder. The Cr particles are accelerated up to 1200 m/s and directed to the substrate, in this case cladding tubes made of Optimized ZIRLO™ alloy. The resulting Cr-coated zirconium cladding is the subject of this work. As-fabricated samples and autoclave tested material are characterized with atom probe tomography and a range of electron microscopy techniques. The scope of the investigation is to evaluate the performances of Cr-coated claddings under operating conditions. Additionally, the nature of the adhesion in cold spray coating and the effects of this deposition method on the substrate are explored. A 10-20 nm thick intermixed bonding region was observed at the Cr/Zr interface of the as-fabricated cladding. This region is deemed to play an important role in the strong adhesion of CS coatings. When exposed to operating conditions, ZrCr2-Laves phase was found to nucleate in the intermixed bonding region. CS deposition involves severe plastic deformation of both coating and substrate. As a result, a 1-2 μm thick nanocrystalline layer can be found in the substrate adjacent to the Cr/Zr interface. After autoclave exposure, a Zr-Cr-Fe phase was discovered precipitating in this nanocrystalline layer at the Zr grain boundaries

Digital aesthetics: the discrete and the continuous

Aesthetic investigations of computation are stuck in an impasse, caused by the difficulty of accounting for the ontological discrepancy between the continuity of sensation and the discreteness of digital technology. This article proposes a theoretical position intended to overcome that deadlock. It highlights how an ontological focus on continuity has entered media studies via readings of Deleuze, which attempt to build a ‘digital aisthesis’ (that is, a theory of digital sensation) by ascribing a ‘virtuality’ to computation. This underpins, in part, the affective turn in digital theory. In contrast to such positions, this article argues for a reconceptualization of formal abstraction in computation, in order to find, within the discreteness of computational formalisms (and not via the coupling of the latter with virtual sensation), an indeterminacy that would make computing aesthetic qua inherently generative. This indeterminacy, it is argued here, can be found by reconsidering, philosophically, Turing’s notion of ‘incomputability’

Development and performance evaluation of accident-tolerant coated fuel claddings for light water reactors

The development of accident tolerant fuel has the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had been delayed for the last few decades. Climate change is an ever-growing public concern, and policies about greenhouse gas emissions are becoming more stringent both at the national and international level. Nuclear energy produces very low carbon emissions and the successful development of new accident tolerant materials might play a role in making this technology a viable solution to this global issue. Coated zirconium claddings are one of the most promising candidates as a near-term response to the need for accident tolerant materials. These coatings can be produced via a range of different technologies, but two main techniques are being currently employed for the development of such coatings: cold spray deposition and physical vapour deposition (PVD). In cold spray, high pressure gas is fed through a nozzle together with a powder. Powder particles are accelerated up to 1200 m/s and directed to the substrate, in this case cladding tubes made of zirconium alloy. In PVD, the coating material is evaporated from a target and sputtered onto the substrate as atoms or ions. The resulting coated zirconium claddings are the subject of this work.As-fabricated samples, autoclave tested material, and specimens tested under simulated accident conditions are characterized with atom probe tomography and a range of electron microscopy techniques. The scope of the investigation is to evaluate the performance of the coated claddings under operating conditions and in simulated accident conditions. Metallic Cr has emerged as the best candidate for accident tolerant coatings for pressurised water reactors. In this work, the focus was on Cr-coatings deposited with cold spray, which performed well in both tested environments. A passivating layer of chromia formed during autoclave exposure, and a protective scale of chromia prevented any oxidation of the Zrsubstrate for up to 40 min in 1200  C steam. The nature of the adhesion in cold spray coatings and the effects of this deposition method on the substrate were studied. The formation of a Cr2Zr phase at the Cr/Zr interface was observed both under autoclave and simulated accident conditions. The search for an effective accident tolerant coating for boiling water reactors is more challenging and many coatings have been tested in autoclave, where PVD (Cr,Nb)N coatings showed the best performance under operating conditions. A 200 nm thick passivating oxide film composed of an outer Cr, Nb, Ni phase and an inner layer of oxidised coating was found after exposure

The ends of media theory

International audienceM. Beatrice Fazi's manifesto for Media Theory

O fim da teoria da mídia

Esse artigo considera o papel da teoria em geral e da teoria da mídia em específico. Ao desafiar a possibilidade de um “fim da teoria” que vem ressoando em debates sobre novas mídias, pretendo mostrar a relevância permanente da investigação teórica. Irei abordar como o ato de teorizar é frequentemente compreendido como a criação de um sistema de abstração que envolve certo grau de distanciamento da realidade que deve descrever. Irei posteriormente expor uma falsa concepção em relação a este distanciamento: por exemplo, a visão de acordo com a qual, se teorizar é abstrair a partir da observação, então abstrair é se desengajar dos fatos. Contra essa visão, irei argumentar que a abstração é intrínseca ao mundo e como o experimentamos
