This paper describes the music emotion recognition system developed at the University of Aizu for the Emotion in Music task of the MediaEval’2013 benchmark evaluation campaign. A set of standard feature types provided by the Marsyas toolkit was used to parametrize each music clip. Arousal and valence are modeled separately using Gaussian Process regression (GPR). We compared performances of the...
The aim of Chapter 2 is to give an overview of the GPR basic principles and technology. A lot of definitions and often-used terms that will be used throughout the whole work will be explained here. Readers who are familiar with GPR and the demining application can skip parts of this chapter. Section 2.2.4 however can be interesting since a description of the hardware and the design parameters o...
Three nonlinear count models, Poisson R.egression (PR), Negative Binomial Regression (NBR), and Generalized Poisson Regression (GPR) are used for assessing the effects of risk factors on agricultural injuries from farm injury data. A sample of 1,322 respondents who participated in the farm safety/injury baseline survey in nine rural counties in Alabama and Mississippi, aged 18 years and older a...
Ground penetrating radar (GPR) method is a non-destructive geophysical method that is used to detect subsurface heterogeneities and also recognition of various shallow targets. In present research, forward and inverse modeling of GPR data applied for archeological study has been made. The study area is Tappeh Hissar, Damghan, in which GPR data along several survey lines have been acquired using...
Assessing program quality and outcomes is essential to improve postgraduate dental education. This study's aims were to document career direction and practice patterns of graduates of the Brigham and Women's Hospital (BWH) General Practice Residency (GPR), to compare BWH GPR outcomes to those of other American GPRs, and to identify characteristics of the BWH GPR program that trainees valued. Th...
Abstract Ballast fouling in railroad substructure is detrimental to railroad track effectiveness and its structural capacity. Ground penetrating radar (GPR) provides a rapid, effective and continuous approach to assess railroad substructure condition. However, unknown ballast dielectric constant and unclear interface between clean and fouled ballast limit the GPR assessment accuracy. In this st...
Subsurface sensing modalities such as Ground Penetrating Radar (GPR) are increasingly being used to assess the condition of aging civil infrastructure by evaluating deterioration within roadways and bridges, and to monitor the security of national borders by the detection of underground tunnels. The need to address these issues is intensifying and, while valuable data are collected using nondes...
روش رادار نفوذی به زمین (GPR) یک روش ژئوفیزیکی غیر مخرب است که قادر به آشکارسازی انواع ناهمگنیهای زیرسطحی و نیز شناسایی انواع اهداف مدفون در اعماق کم است. در پژوهش حاضر مدلسازی پیشرو و وارون دادههای GPR با هدف کاربرد در زمینه شناسایی لولههای مدفون در زیرزمین انجام شده است. در محوطه دانشگاه صنعتی شاهرود بهمنظور شناسایی موقعیت عبور لولههای انتقال سیالات هیدروکربوری، تعدادی پروفیل GPR با است...
امروزه انتقال و نگهداری مواد سوختی، آب و همچنین سایر منابع انرژی توسط لوله ها، مخازن و کابل های مدفون در زیر سطح زمین در مناطق شهری و بین شهری امری ضروری و مهم است، به طوری که باعث ایجاد شبکه های زیرزمینی عظیم با صرف هزینه های فراوان شده است. مسئله ای که پس از ایجاد چنین شبکه هایی دارای اهمیت خاصی است، نگهداری و پشتیبانی از این سازه های دست بشر برای جلوگیری از تخریب های احتمالی می باشد. این تخر...
Ground penetrating radar (GPR) is a non-destructive geophysical method that uses electromagnetic waves to image the subsurface. A typical GPR system has three main components: transmitter and receiver, directly connected to the transmitting and receiving antennas, and a control unit. Electromagnetic pulses are transmitted into the subsurface and the earth response is recorded. The GPR method is...
