AbstrakDalam pemotretan panorama diperlukan alat bantuyang dapat menentukan besar pergeseran arah kamera secara konsisten agar diperoleh foto-foto yang pas tanpa ada bagian yang hilang karena tidak terfoto. Dengan didapatnya foto yang saling tersambung maka dapat dilakukan penggabungan foto untuk menjadi sebuah foto panorama. Penggabungan foto-foto hasil pemotretan dapat dilakukan dengan cara image stiching (menjahit), yaitu menyambung foto-foto hasil pemotretan dari satu titik tetap.Alat yang dirancang merupakan alat yang otomatis menentukan besar sudut perputaran head kamera dengan input jumlah pergeseran dan akan melakukan pemotretan (triggering) bila sudut sudah sesuai dengan input. Pengujian sistem meliputi pengujian variasi jumlah pergeseran menggunakan satu nilai focal length dengan memvariasikan nilai pan dan tilt. Pengujian ketelitian konsistensi pergeseran dan arah kamera. Pengujian besar perpotongan setiap pergeseran dengan menggabungkan 2 foto yang sejajar kemudian dicari seberapa besar irisan yang dihasilkan.Berdasarkan pengujian menggunakan kamera DSLR diperoleh hasil alat dapat bekerja dengan baik secara otomatis berdasarkan nilai input pan dan tilt serta dapat melakukan triggering. Pergeseran efisien diperoleh pada nilai pan sebanyak 9 kali dan tilt 4 kali menggunakan lensa dengan focal length 18 mm. Hasil analisa tingkat kesalahan pergeseran bernilai kurang dari 3% yang menjadikan alat ini stabil dan konsisten dalam pergerakannya. Kata kunci—foto panorama, Arduino Uno, otomasi, fotografi  AbstractIn landscape photography, some supporting devices are needed to assign how much the camera’s shifting consistently is. It is needed to get good photos without any blank spot photos. The linked photos could be rendered to be a landscape photo using a photography software. It is could be done by image stiching, a way to stich photos taken from one constant taking point.  The device is an automatic device which could assign how much the rotation degree of the camera’s head with given input, how much the shift is. It will take a shot if the rotation degree is appropriate with the given input. The system testing by variying the shift value of camera using one focal length value. The accuration test of the consistency of camera’s shift and camera’s direction. The error value could be determined by joining two parallel photo.According to the testing, tool can work automatically and also trigering can do well. Efficient shift in the number of photos and good results using the pan 9 times and tilt 4 times. The results of the error rates shift analysis have value less than 3% and that makes the tool quite stable and consistent in its movements. Keywords— panoramic photo, arduino uno, automation ,photography.

Digital representation of an artefact is necessary in order to measure, admire and analyse such ancient pieces. For the purpose of storing, recoding and transmitting information, digital photographs may be enough. However, in the examination purposes of an artefact, a 3D presentation is invaluable as it allows the object viewpoint to be modified freely and 3D measurements to be taken on object features. This chapter describes the system by which 3D models from photographs can be acquired, without the need for the calibration of system geometry such as the camera focal length, relative motion of the camera and object, and the relative positions of the camera and object. This system instead computes the representation of all possible objects and camera configurations which are consistent with the given image. The first section discusses how tracking points observed in 2D images allows for the computation of the relative camera and object geometry. The second section discusses the construction of a triangulated 3D model from the object projections. The third section discusses the refinement of the model based on surface texture.

ABSTRACTEarly efforts to apply knowledge of dialect differences to reading stressed the importance of the distinction between differences in pronunciation and mistakes in reading. This study develops a method of estimating the probability that a given oral reading that deviates from the text is a true reading error by observing the semantic impact of the given pronunciation on the child's reading of the text that immediately follows. A diagnostic oral reading test was administered to 627 children who scored in the 33rd percentile range and below on state-mandated assessments in reading in Philadelphia, Pennsylvania, Atlanta, Georgia, and California elementary schools. Subjects were African American, European American, and Latino, including Latinos who learned to read in Spanish and in English first. For 12 types of dialect-related deviations from the text that were studied, the error rates in reading the following text were calculated for correct readings, incorrect readings, and potential errors. For African Americans, many of these potential errors behaved like correct readings. The opposite pattern was found for Latinos who learned to read in Spanish first: most types of potential errors showed the high percentage of following errors that is characteristic of true errors.

SummaryAn automatic blood pressure recorder (Bosch Tonotest) was evaluated on a subsample of the study population of the Munich Blood Pressure Study I (MBS I). The purpose of this evaluation was to test an automatic device for its usability in screening programs like the Munich Blood Pressure Program (MBP). For all subjects in MBS I three blood pressure measurements were taken using the random-zero sphygmomanometer. For a subsample of subjects, in addition to the three blood pressure measurements with the random-zero sphygmomanometer, two measurements were made, one again with the random-zero sphygmomanometer and one with the automatic device. These last measurements were made in alternating sequence (cross-over design).The automatic device tends to underestimate the systolic blood pressure while the diastolic blood pressure readings agree well. The ability to identify people with high blood pressure was worse for the automatic device. The differences between the automatic device and the random-zero sphygmomanometer in sensitivity, specificity, error rates and their implications for a screening program are discussed.

The Given

In the field of photogrammetry, the optical system, usually represented by the glass lens, is used for metric purposes. Therefore, the aberration characteristics of such a lens, inducing deviations from projective imaging, has to be well known. However, the most important property of the metric lens is the stability of its glass and mechanical elements, ensuring long-term reliability of the measured parameters. In case of a focus-variable lens, the repeatability of the lens setup is important as well. Lenses with a fixed focal length are usually considered as “fixed” though, in fact, most of them contain one or more movable glass elements, providing the focusing function. In cases where the lens is not equipped with fixing screws, the repeatability of the calibration parameters should be known. This paper derives simple mathematical formulas that can be used for measuring the repeatability of the focus-variable lenses, and gives a demonstrative example of such measuring. The given procedure has the advantage that only demanded parameters are estimated, hence, no unwanted correlations with the additional parameters exist. The test arrangement enables us to measure each demanded magnification of the optical system, which is important in close-range photogrammetry.

The Arduino UNO microcontroller based smart portable soil testing system is developed to determine the values like pH content and moisture level. This can be done using the sensor respectively to check the values. The GSM Module which uses the mobile communication to communicate the value to the given mobile. The communication method used here to retrieve the values whenever it is necessary and after getting the values it would be displayed in LCD. Then when the button is pressed, the GSM starts to work, search for the signal and after responding to the signal the values are sent to the registered mobile. This method would be easier to check the value of soil so that it will be viewed whenever the values are needed. It describes that the values are available at our doorstep because it is smart portable monitoring system. This project helps us to create a new idea to do further additional functions that can be done.
