Monolithic Composite “Pressure + Acceleration + Temperature + Infrared” Sensor Using a Versatile Single-Sided “SiN/Poly-Si/Al” Process-Module
No full textWe report a newly developed design/fabrication module with low-cost single-sided “low-stress-silicon-nitride (LS-SiN)/polysilicon (poly-Si)/Al” process for monolithic integration of composite sensors for sensing-network-node applications. A front-side surface-/bulk-micromachining process on a conventional Si-substrate is developed, featuring a multifunctional SiN/poly-Si/Al layer design for diverse sensing functions. The first “pressure + acceleration + temperature + infrared” (PATIR) composite sensor with the chip size of 2.5 mm × 2.5 mm is demonstrated. Systematic theoretical design and analysis methods are developed. The diverse sensing components include a piezoresistive absolute-pressure sensor (up to 700 kPa, with a sensitivity of 49 mV/MPa under 3.3 V supplied voltage), a piezoresistive accelerometer (±10 g, with a sensitivity of 66 μV/g under 3.3 V and a −3 dB bandwidth of 780 Hz), a thermoelectric infrared detector (with a responsivity of 45 V/W and detectivity of 3.6 × 107 cm·Hz1/2/W) and a thermistor (−25–120 °C). This design/fabrication module concept enables a low-cost monolithically-integrated “multifunctional-library” technique. It can be utilized as a customizable tool for versatile application-specific requirements, which is very useful for small-size, low-cost, large-scale sensing-network node developments
“Capacitive Sensor” to Measure Flow Electrification and Prevent Electrostatic Hazards
No full textAt a solid/liquid interface, physico-chemical phenomena occur that lead to the separation of electrical charges, establishing a zone called electrical double layer. The convection of one part of these charges by the liquid flow is the cause of the flow electrification phenomenon which is suspected of being responsible of incidents in the industry. The P’ Institute of Poitiers University and CNRS has developed an original sensor called “capacitive sensor” that allows the characterization of the mechanisms involved in the generation, accumulation and transfer of charges. As an example, this sensor included in the design of high power transformers, could easily show the evolution of electrostatic charge generation developed during the operating time of the transformer and, therefore, point out the operations leading to electrostatic hazards and, then, monitor the transformer to prevent such risks
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
SISTEM AKUNTANSI PEMBELIAN BAHAN BAKU PADA PT. AGRONESIA “ INKABA “ DIVISI INDUSTRI TEKNIK KARET
No full textPemahaman seseorang terhadap bidang ilmu pengetahuan sangat terkait dengan lingkungan sekitar dan banyaknya informasi yang diterima. Oleh karena itu Kerja Praktek merupakan tambahan pengetahuan sekaligus pengalaman dunia kerja yang sesungguhnya.
Dalam memenuhi salah satu tugas mata kuliah Kerja Praktek pada Diploma III Jurusan Komputerisasi Akuntansi Fakultas Teknik dan Ilmu Komputer Universitas Komputer Indonesia Bandung, mahasiswa semester IV diwajibkan melaksanakan Kerja Praktek.
Pelaksanaan Kerja Praktek ini dimaksudkan agar mahasiswa dapat mengenal lebih jauh ruang lingkup pekerjaan dan mekanisme kerja itu sendiri dengan harapan mahasiswa dapat mempraktekkan ilmu pengetahuan dan teori-teori yang telah diperoleh selama masa perkuliahan ke dalam Kerja Praktek yang sesungguhnya.
Dari beberapa faktor yang mempengaruhi produksi, bahan baku merupakan salah satu faktor penting dalam menjamin kelangsungan produksi suatu perusahaan. Bahan baku harus tersedia sesuai dengan kebutuhan dan dijaga baik kualitas maupun kuantitasnya, hal ini disebabkan karena bahan baku merupakan salah satu syarat kuantinuitas produksi yang harus tetap dijaga.
Bahan baku harus sesuai dengan kebutuhan perusahaan yang diperlukan. Kejelian dalam hal ini bagian pembelian yang bertanggung jawab dalam pemilihan bahan baku yang terjamin baik kualitas rekanan atau supplier yang dapat mensuplai bahan baku sesuai dengan yang diharapkan oleh perusahaan sehingga dapat menjamin kelangsungan tersedianya bahan baku.
Dengan pertimbangan tersebut maka Laporan Kerja Praktek ini ditujukan untuk mempelajari bagaimana suatu Sistem Akuntansi Pembelian diterapkan perusahaan didalam menangani aktivitas pembelian bahan baku pada perusahaan tersebut. Dalam hal ini penulis mempelajari dan melakukan Kerja Praktek di PT. AGRONESIA “ Inkaba “ Divisi Industri Teknik Karet yang didalam Sistem Akuntansi Pembelian bahan baku dalam negeri secara kredit, karena perusahaan ini adalah perusahaan manufaktur yang besar sehingga membutuhkan bahan baku yang cukup banyak dalam melakukan produksinya.
Dengan mempelajari hal tersebut diatas, maka penulis memilih judul “Sistem Akuntansi Pembelian Bahan Baku pada PT. AGRONESIA “ Inkaba “ Divisi Industri Teknik Karet”
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
