Perancangan Sensor Berat Bending Serat Optik dan Laser Pointer
No full textIn this modern age of technology development is very fast and have an impact on all aspects of the work of so many application of science and technology designed to simplify a system work. Cases in poorly loads monitoring, especially heavy vehicles. One of contributing factor is the relatively long time to detect the weight of a vehicle. Weight In Motion (WIM) technology comes with the ability to knows the weight of an object quickly. One of important component in WIM system is a sensor. The purpose of research is to investigate the optical fiber as a load sensor. Results of the investigation are expected to know the potential of optical fiber sensor for statics load and dynamics load. The fiber optic sensor use microbending principle and then detect power losses in fiber optics.Microbending is one type of bending when the surface of the fiber optic having pressure and than resulting deformation in the optical fiber core. In this research has been made fiber-optic load sensors that can detect the load up to 100 kg. The sensor system consists of a layer of rubber and optical fiber is in the centre of layers with steel wire array as a triggers bending.Di zaman yang modern ini perkembangan teknologi sangat cepat dan berdampak pada segala aspek bidang pekerjaan sehingga banyak penerapan ilmu dan teknologi yang dirancang untuk mempermudah suatu sistem pekerjaan. Kelebihan muatan merupakan kasus tidak terpantaunya berat beban kendaraan. Untuk mengatasi kendala tersebut maka hadir teknologi Weight In Motion (WIM) yang memungkinkan berat suatu benda dapat diketahui secara cepat. Salah satu komponen penting dalam sistem WIM adalah sensor. Tujuan penelitian ini adalah melakukan investigasi terhadap serat optik sebagai sensor beban. Hasil investigasi diharapkan dapat mengetahui potensi serat optik sebagai sensor beban baik beban diam maupun beban berjalan. Prinsip kerja sensor ini adalah memanfaatkan prinsip rugi-rugi microbending fiber optic. Microbending adalah salah satu tipe bending yang terjadi ketika permukaan serat optik mengalami tekanan kemudian menyebabkan terjadinya deformasi pada inti serat optik. Dalam penelitian ini telah dibuat sensor beban menggunakan serat optik yang mampu mendeteksi beban sampai dengan 100 kg. Sistem sensor terdiri dari lapisan karet dan serat optik berada ditengah dengan pemicu bending berupa jajaran kawat.89 HalamanKertas Karya Diplom

No full textHas done research on fiber-optic-based load sensor with microbending
principle. This study includes some stability testing of the laser, the influence
microbending, validity and reliability of the sensors to find the right design and
the level of the sensor response when the load placed on the sensor so that the
sensor can be applied to the vehicle load. The test uses a laser source with a
wavelength of 1310 nm, many kinds of optical fiber, rubber lining, load, steel
wire, modified sensor (artificial Physics Research Center), a photodetector, Data
Translation DAQ, and software Weight in Motion made LIPI Physics Research
Center. Obtained some results of studies that met the laser stability test statistic T,
the influence microbending significant influence on the response of the load
sensor with ANOVA at the 0.05 level, with the sensor hysteresis error < 5%, the
sensor validation by polynomial equations and reliability of the sensor satisfied

Abstract 1122‐000190: Persistent DWI Signal for 18 Months in Ischemic Stroke Patient with Carotid Web
No full textIntroduction: Diagnostic tools for acute ischemic infarcts include the use of DWI sequence on MRI to identify acute infarcts is especially useful since lesions can become hyperintense on this sequence very rapidly (Albers 1998). Over the next 15 days, DWI hyperintensity slowly decreases back to isointense. In some patients, however, there is persistent DWI hyperintensity past 1 month. There are theories that these persistent areas exhibit delayed onset infarct, prolonged ischemia, or perhaps different repair processes (Rivers, et al 2006). To this day, all DWI signals have been known to resolve within a few months even for persistent hyperintensities (Rivers, et al 2006). Carotid webs are a rare form of fibromuscular dysplasia that protrudes from the intimal tissues of carotid arteries. They are shelf‐like projections that grow into the lumen and disrupt normal blood flow (Zhang, et al 2018). These outgrowths are theorized to lead to ischemic strokes due to flow stasis and subsequent embolization of clots that form (Zhang, et al 2018). There is no consensus on the best management of carotid webs, and secondary prevention of recurrent strokes range from medical management to carotid stenting. Methods: This is a case report, and information for the patient was gathered through review of medical records on the EMR. Results: We present a case of ischemic stroke in the right basal ganglia/corona radiata, who presented with left sided weakness. The patient was found to have prediabetes, HTN, and HLD. However, she had recurrence of her symptoms over the next 18 months (figure 1). Repeat MRIs showed persistent DWI hyperintensity that slowly decreased in size and signal intensity over this period but in the same area as the initial infarct. The rest of the work up was only significant for a carotid web in the right internal carotid artery identified on conventional angiography. Ultimately she was managed with medical therapy including aspirin, statin, and antihypertensives. Conclusions: It is unclear whether the carotid web is associated with persistent DWI for such an extended time frame. There is very little research that explores the pathophysiology of ischemic strokes from carotid webs. In addition, there is even less information about the physiology of an evolving infarct that shows persistent DWI signals for such an extended time frame. Further studies that look into carotid webs may help us understand the best long term management in such patients. Future studies that explore the physiology of ischemic strokes that show such persistent DWI signals may elucidate and perhaps expand upon current management options and possibly identify new areas for intervention
Strike Three Yer Out!? : Examining the Constitutional Limits on the Use of Prior Uncounseled DWI Convictions to Impose Mandatory Prison Sentences on Repeat DWI Offenders
Full text linkThis Comment examines the constitutional implications of using prior uncounseled DWI convictions to incarcerate repeat DWI offenders. The Comment reviews the Supreme Court decisions that established the right to court-appointed counsel for the indigent accused and examines the federal constitutional limitations on the collateral use of prior uncounseled DWI convictions. It also critically evaluates state court decisions involving the collateral use of prior uncounseled DWI convictions. The author concludes that, because an uncounseled conviction is inherently unreliable, it should not be used to mandatorily incarcerate a DWI repeat offender

The prevention of young driver's DWI (driving while intoxicated) and RWDI (riding with a driver under influence) in Europe: A social-sequential model
No full textInspired by the 'critical incident technique' of McKnight et al. (1995) who analyzed 12,000 drivers' decisions leading to (or not to) DWI, and indentified the influence of social, motivational, and economic factors, the author has developed a social-sequential model of young drivers' DWI and RWDI prevention
