Dampak Lalu Lintas Pada Ruas Jalan M. Thamrin dan Simpang M. Thamrin-Jl. Argopuro Akibat Pembangunan dan Ruko Lawang View.
Get PDFLawang View adalah salah satu perumahan dan ruko yang akan dibangun di ruas Jalan M. Thamrin Kecamatan Lawang –Kabupaten Malang. Sebagai sumber bangkitan dan tarikan pergerakan , maka sangatlah penting untuk mengkaji tingkat kelayakan pembangunan perumahan dan ruko tersebut. Ruas Jalan M. Thamrin dan Simpang Jalan M. Thamrin –Jl. Argopuro adalah salah satu ruas dan simpang dengan volume lalu lintas padat. Ruas jalan tersebut berada di kawasan perkantoran dan niaga dan juga merupakan akses utama yang menghubungkan Malang dengan kota-kota besar lainnya. Simpang Jl. M.Thamrin-Jl. Argopuro merupakan salah satu simpang tak bersinyal di Kecamatan Lawang. Volume Lalu lintas Simpang tersebut adalah tinggi karena banyak terdapat pusat tarikan pergerakan di sepanjang Jl. Argopuro. Studi ini bertujuan untuk mengevaluasi dampak pembangunan perumahan ruko Lawang View terhadap ruas jalan M. Thamrin dan Simpang Jl. M.Thamrin-Jl. Argopuro.
Survai distribusi arus lalu lintas diperlukan unttuk mengetahui kinerja lalu lintas kondisi eksisting dan sebagai pembanding untuk mengetahui besarnya perubahan yang terjadi terhadap kinerja lalu lintas setelah pembangunan perumahan dan ruko . Survai dilakukan dengan interval waktu 5 menit. Untuk menentukan jam puncak digunakan metode moving average . Pada ruas jalan M.Thamrin, berdasar hasil survai maka diperoleh jam puncak pada hari Senin, 2 Mei 2005.
Kondisi ini disebabkan pada hari Senin merupakan hari pertama dimulai aktivitas kerja dan pendidikan. Sedang dari hasil survai di Simpang Jl. M.Thamrin-Jl. Argopuro, diperoleh data jam puncak pada hari Sabtu 7 Mei 2005 periode 15.55-16.55. Pembahasan pada studi berdasarkan metode MKJI 1997. Analisa peningkatan kinerja operasional ini dilakukan dengan perbaikan geometri pada ruas jalan dan simpang, penerapan system sinyal lalu lintas (SSLL) pada simpang, dan kombinasi penerapan SSLL dengan kanalisasi pada simpang, dan kombinasi penerapan SSLL dengan kanalisasi di simpang.
Hasil analisa kinerja ruas jalan M.Thamrin pada kondisi eksisting menunjukkan nilai Derajat Kejenuhan (DS) sebesar 1,13, sehingga ruas jalan dalam kondisi kritis. Nilai DS ini secara otomatis akan meningkat karena adanya pembangunan perumahan dan ruko. Dari hasil analisis kinerja ruas setelah pembangunan didapat Derajat Kejenuhan (DS) sebesar 1,16 sehingga terjadi peningkatan 3,13% dari kondisi eksisting. Dengan ketersediaan lahan yang cukup, perbaikan geometri merupakan salah satu alternatif penanganannya. Dengan rencana penambahan lebar ruas jalan dari 7,5 meter menjadi 10 meter, maka didapat nilai DS sebesar 0,95.
Analisa kinerja simpang kondisi eksisting menghasilkan DS 1,15 dengan adanya perubahan lahan, memberi dampak meningkatnya DS simpang sebesar 1,20 dengan tundaan simpang sebesar 55. Dengan kombinasi penerapan SSLL dan kanalisasi pada simpang, perbaikan kinerja meningkat secara signifikan dengan derajat kejenuhan sebesar 0,621 serta tundaan yang terjadi sebesar 14,68 det/smp
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Real-time inter-row tree detection and tracking techniques for unmanned vehicle-based on simultaneous localization and mapping approach / Norashikin M. Thamrin
Get PDFIn this work, an inter-row tree detection and tracking techniques based on Simultaneous Localization and Mapping (SLAM) method is developed specifically for a well-structured agricultural field where the trees are planted uniformly with certain distance that leaves it with number of inter-row spaces. The existing rows has created opportunities for an autonomous vehicle to navigate in between the trees to perform the plantation activities such as scouting, monitoring, rowing, pesticide spraying and others. Unfortunately, the complicated conditions in the farm impair this solution. Such conditions like large canopy of leaves covered the top of the farm has led difficulty on the Global Positioning System (GPS) signal to penetrate the field and set a stable communication with the autonomous vehicle. In addition, a dark environment is created around the farm which could worsen the usage of image as artificial lighting must be added to distinguish the landmarks from the background. Therefore, a new approach to detect the landmarks and navigate in the farm based on the lightweight sensors and less computation effort is proposed. In this method, the tree detection and diameter estimation techniques implement the modified tree-triangle diameter technique by using innovative technique based on infrared sensors

In this method, the tree detection and diameter estimation techniques implement the modified tree-triangle diameter technique by using innovative technique based on infrared sensors. Then, in substituting the GPS signal problems during the navigation and localization problems, a curve-based navigation approach is formulated. The path is planned based on the third-polynomial Bezier curve by projecting series of waypoints to create a solid path from one point to another. Then, the trajectory plan is derived for the autonomous vehicle to follow these waypoints during the navigation. At the same time, the mapping technique implements the memory utilization method in order to ease the localization process as well as landmarks mapping in the visual map which is oriented in two-dimensional coordinate format. These functions are created, formulated and tested thoroughly in the embedded microcontroller development board platform by using dsPIC30F6014A chip on the omnidirectional vehicle platform. A positive result was found in tree diameter estimation, navigation techniques and landmark mapping with the average error of 0.61 cm, 4.0 cm and 8.9 cm, respectively. These results are compared with the previous research work from other researchers and showed remarkable and promising results to be implemented in the agriculture field with further enhancement and recommendation
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
