Analisis Simpang Bersinyal Pada Simpang 4 Jl. Siliwangi Kota Tasikmalaya

Transportation problem is one of the problems that is faced in Tasikmalaya City especially at the intersection. Congestion problems and traffic conflicts often occur at a signal especially in intersection on Siliwangi road Tasikmalaya. One of the efforts made to reduce traffic conflicts and optimize the performance of the junction is by setting up the junction and optimizing the Simpang. The purpose of this research is to know the performance of intersection on Siliwangi road Tasikmalaya and provide recommendations for precise handling, as well as analyzing the traffic conflicts that occurred in the junction. The method used in the performance analysis of the junction signal is to use the calculations in the PKJI 2014, while for analysis of traffic conflicts used to determine the severity of the conflict at the intersection on Siliwangi road Tasikmalaya is using the method Traffic Conflict Technique (TCT). After analysis, the performance in the intersection on Siliwangi road Tasikmalaya Tasikmalaya has approached the critical number of the degree of saturation (DS) of 0.7 with level D. In addition to these problems, there is a traffic conflict crossing as many as 230 events (55%), merging as many as 145 events (35%) and diverging as many as 41 occurrences (10%). With the handling and recommendation of phase setting and cycle time setting, it is proven to suppress and minimize the decline of junction performance level to C level with the value of saturation of 0.58. This will also impact the reduction in the amount of traffic conflicts that occur.Keyword : intersection, traffic conflict, PKJI 2014, phase, cycle time

Frequency adaptive sliding fourier transform for synchronizing VSI to the grid

Sliding Discrete Fourier Transform (SDFT) is very efficient regarding computational load and it possesses a very fast phase angle detection with excellent harmonic rejection at nominal frequency. However, at off-nominal frequency, SDFT generates errors in both magnitude and phase angle due to spectral leakage. This paper introduces a workaround for Fourier Transform to handle this disability under off-nominal frequency while avoiding variable-rate sampling. Sliding Fourier Transform (SFT) is used as a phase detector for a phase-locked loop whose output frequency is used to drive the SFT. The paper revisits the mathematics of Fourier Transform (FT) in a three-phase setting via a time-domain approach to show a newly proposed filtering technique for the double-frequency oscillation just by summing the FT sine/cosine filter outputs of the three individual phases. Also, the analysis aims to determine and correct the phase and magnitude errors under offnominal frequency operation. The proposed technique (SFT-PLL) is tested in real time on dSPACE DS1202 DSP using voltage vectors that are pregenerated to simulate the most adverse grid conditions. The testing scenarios compare the performance of the SFT-PLL with that of the Decoupled Stationary Reference Frame PLL (dαβPLL). The results prove that SFT-PLL is superior to dαβPLL.

Pengaruh Fase Apill Pada Simpang Terhadap Perilaku Menunggu Pengguna Sepeda Motor Di Kota Tegal

Intersection is a critical area on a highway where a point of conflict and where bottlenecks due tothe merging of two or more roads. The junction arrangements that do not fit will cause trafficproblems, particularly the intersection you have installed APILL. Violations often occur are agresivedriving behavior in the form of the behavior of the wait. Based on existing conditions, the behaviorof waiting that occurred at an intersection with two and four phase settings have a difference.Violations committed by users i.e. a motorcycle broke through APILL, stop at the stop line and theopposing lanes consuming. APILL phase setting should resolve the problems of the particularbehavior of the wait. Methods of analysis used i.e. the dependent samples T-test test with SPSS16.0 program use. Based on the current test sig (2-tailed) of > 0.05 0.628 then it can be concludedthat there was no significant difference between the behavior of waiting at an intersection that has asetting of two and four phases.

PANDUAN PELAKSANAAN TA MAHASISWA DKV FSD UNM

Implementation of the Final Project (TA) by DKV FSD-UNM students do not have a definitive official guide. Consequently, systematic proposal, the implementation process, and systematic reports on TA produced students vary greatly due to the implementation process and the systematic writing TA students rely on experience, understanding, guidance supervisor respectively, as well as examples of proposals and reports referred to by the students. Conditions that underlies so DKV Studies Program FSD-UNM is necessary to immediately provide implementation guides TA. TA implementation guides are arranged in the form of a book that will be used in Visual Communications Design Studies Program of the Faculty of Art and Design University of Makassar. The method used in this research and development to adapt the model of development research is broadly divided into five stages, namely: (1) Phase analysis of needs, (2) The design phase, (3) stage of development, (4) Phase evaluation, and (5) Phase-setting system. Especially for the first year, research and development activities are new to the design stage. Subjects were lecturers and students TA Visual Communication Design Studies Program Faculty of Arts and Design is currently working on TA. The research data is needed at the design stage is obtained through observation and FGD, which was then analyzed quantitatively and qualitatively by type. The results obtained in this first stage in the form of a draft guidebooks TA and research instruments. TA Handbook has been designed with attention to competency courses, the characteristics of students and courses, and development principles guidebooks. The guidebooks in draft guide prepared by taking into account also the logic and system aspects, which in the later stages still need to be refined.

Quantitative solid-phase assay to measure deoxynucleoside triphosphate pools

Deoxyribonucleoside triphosphates (dNTPs) are the reduced nucleotides used as the building blocks and energy source for DNA replication and maintenance in all living systems. They are present in highly regulated amounts and ratios in the cell, and their balance has been implicated in the most important cell processes, from determining the fidelity of DNA replication to affecting cell fate. Furthermore, many cancer drugs target biosynthetic enzymes in dNTP metabolism, and mutations in genes directly or indirectly affecting these pathways are the cause of devastating diseases. The accurate and systematic measurement of these pools is key to understand the mechanisms behind these diseases and their treatment. We present a new method for measuring dNTP pools from biological samples, utilising the current state-of-the-art polymerase method, modified to a solid-phase setting and optimised for larger scale measurements.

Switch-Beam Vivaldi Array Antenna Based On 4x4 Butler Matrix for mmWave

It will be diffcult to use either omnidirectional or fixed beam antenna due to the high propagation losses caused by atmospheric absorption at mmWave for 5G mobile communication. Several studies have been conducted recently using butler matrix which is part of switchable antenna with some advantages such as simple, minimal cost, low loss, etc. Previous studies also have designed vivaldi array antenna at 28 GHz which provides a fix beam directional radiation pattern with narrow beam that requires real phase setting. However, there has been no research using vivaldi antenna with butler matrix, whereas it has some advantages such as wide bandwidth, high gain, high directivity, etc. This paper proposed 4x4 butler matrix integrated with vivaldi antenna by using phase shift of 45 . The design is developed on a single layer of Rogers RT5880 with dielectric constant 2.2 and thickness 0.254 mm. Best results of simulation were picked for overall system at 28 GHz, and the results of antenna as follows: the return loss was below -10 dB, the realized antennas gain was 10.2 dB with unidirectional radiation pattern and bandwidth antenna of 6 GHz that covers from 25 GHz to 31 GHz. The butler matrix average phase di erent between output port are -44.106°, 137.38°, -137.66°, 43.95° with phase err°r °f 0.894°, 2.38°, 2.66°, 1.06°. Antenna array that has been given di erent phase by butler matrix is able to shift radiation pattern on the input port successively with range of beam that can be achieved equal to 185o.
