It has different characteristics and have a high ability to distinguish a person. "Gait” analysis, mapping human body points is todays advanced technology. Stages of "gait" processing start from segmentation, extraction until recognition. This paper discusses the segmentation and extraction of gait features. Thinning methods with Most Prominent Ridge Line (MPRL) algorithms to form the skeleton bones of human beings is used. The resulting skeleton image is used for features gait extraction through annular analysis. Method for feature extraction used is Hough transformation. The resulting features are grouped according to distance and angle. This grouping determines the location of features on an image skeleton. The next process is to calculate the distance between feature and angle formed. There are ten features obtained. Four features of a group spacing distance of the front foot until the heel of the hind legs, hands up to the front axle center of the chest, arms rear axle until the middle of the chest and arms front to the back of the hand. Six other features are the result of measurement angle of the front knee, ankle front, rear ankle, knee hind legs, forearms and elbows behind the elbow sleeves.

Lembaga ini merupakan lembaga yang menyelenggarakan pelatihan komputer bagi mahasiswa Universitas Gunadarma. Sistem e-recruitment ini dirancang untuk mengatasi kelemahan sistem yang saat ini berjalan. Kelemahan dirasakan oleh para stakeholder lembaga meliputi pihak laboratorium, pihak panitia seleksi, dan pihak mahasiswa sebagai calon asisten. Tahapan perancangan dimulai dari analisis sistem berjalan untuk mendapatkan gambaran tentang proses bisnis, mendefinisikan kebutuhan sistem dari aspek perbaikan proses dan aktifitas sistem, serta mendefinisikan kebutuhan sistem dari aspek penyimpanan data. Tahapan berikutnya adalah perancangan model sistem menggunakan diagram UML, meliputi diagram use-case, diagram aktifitas, dan diagram sequence. Hasil rancangan yang telah diperoleh dapat diterapkan untuk pembuatan aplikasi berbasis web. Dengan adanya rancangan sistem e-recruitment ini dapat membantu memberikan gambaran model sistem yang akan berlaku pada situs web e-recruitment yang akan dikembangkan.

Due to various features of their construction make it impossible to determine both shear stress and shear rate at the same known point in the equipment. The flow curve therefore can not be constructed from data obtained with such devices. Most of these unsatisfactory instruments give complex reading functions of several type of fluid properties. The aim of this study will examine the viscous properties and to make curve of mud slurry by horizontal pipe as viscometer. These viscometer determine relationships between shear stress and shear rate. The diameter of pipe was 12,7 mm. The length of pipe was 1000 mm. Calculated the shear stress and the shear rate by measuring the pressure loss gradient and the gradient of velocity, respectively. Weight fraction of mud slurry were 20 %, 30 % and 45 %. The results indicated the apparent viscosity of mud slurry is not proportional to the shear stress and shear rate but the relationship could be approximated by power law’s mode with the index n = 0.93 – 1.0 Sat, 01 Dec 2007 00:00:00 GMT http://hdl.handle.net/123456789/7002 2007-12-01T00:00:00Z http://hdl.handle.net/123456789/7001 Title: PERBANDINGAN UNJUK KERJA FREON R-12 DAN R-134a TERHADAP VARIASI BEBAN PENDINGIN PADA SISTEM REFRIGERATOR 75 W Authors: Ridwan, Ridwan Abstract: Refrigerant very important variable in application refrigerator system. The purpose this research investigation the comparison Coefficient Of Performance (COP) Refrigerant 12 (R.12) versus Refrigerant 134a (R.134a) in refrigerator 75 W. Cooling load on the refrigerator using water each volume 100 ml, 200 ml, and 300 ml at temperature 28 oC. Decreasing temperature of water from 28 oC until 0 oC investigate every five minutes. Temperature out – in to Condenser, evaporator and pressure out of capillary tube each of measure using digital thermometers and pressure gauge. From experiment and data analysis show that COP R.134a higher than R. 12 each variation cooling load. Mon, 21 Nov 2005 00:00:00 GMT http://hdl.handle.net/123456789/7001 2005-11-21T00:00:00Z
