Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
No full textRepetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms
Lateral performance of a Pres-Lam frame designed for gravity loads
No full textThis paper analyses the lateral load performance of a post-tensioned timber (Pres-Lam) frame which was designed with the primary function of supporting gravity loading. A full scale, two bay frame was used and subjected to quasi-static horizontal displacement. A total of four tests were performed, one with only the post-tensioning cables to resist horizontal loading and three with the addition of sacrificial steel elements externally attached and acting as dissipative reinforcing. This external reinforcing increased the moment capacity of the frame connections and the ability of the frame to release energy through hysteretic damping. Following a description of the test setup the results show that although the primary functions of the post-tensioning is to reduce section height and increase bay length under gravity loading it will also provide a significant contribution to the lateral resistance of the structure. Finally, a simplified design procedure is presented which allows assessing the magnitude of this contribution
REDUCTION OF THE VIBRATION-ROTATION-LAM HAMILTONIAN
No full textAuthor Institution: Department of Physics, Texas Tech UniversityThe vibration-rotation-LAM Hamiltonian requires two independent separation conditions to reduce the Coriolis interaction and the vibration-LAM kinetic energy interaction. In the limit of the LAM approaching a SAM, the effective vibration-rotation Hamiltonian and/or energy must reduce to the usual vibration-rotation Hamiltonian when no internal motion is a LAM. We show how to perform this reduction, especially as it relates to the T-and R-transformations and the normal coordinate transformation
16: Skepticism and the Skeptical Skeptics Who Use It
No full textA recent trip to the Creation Museum caused producer Sandra Bertin to be very skeptical of, well, skepticism. Sandra returned to the studio to interrogate the idea of skepticism with host of the show Andy Cullison and our other producer, Christiane Wisehart. We turn skepticism inside out and upside down with philosopher Barry Lam and geologist Jeane Pope
Paving the Fourth Way: The Singapore story
No full textThis maiden report arose from a roundtable session held on 1 March 2011, in conjunction with the visit of the 5th CJ Koh Professor Andy Hargreaves, from Boston College’s Lynch School of Education. The Fourth Way is a book authored by Hargreaves and Dennis Shirley. In this report, Professor Hargreaves talks about what the Fourth Way is all about and his thoughts about why Singapore is considered to be paving the fourth way. The report also features key figures in Singapore’s education landscape, across the entire spectrum of the system, on developments in the areas of K-12 education, teacher education, educational leadership programmes, and educational research in general
PERANCANGAN APLIKASI ELECTRONIC MEDICAL RECORD (EMR) PADA INSTALASI RAWAT INAP BERBASIS WEB
No full textPelayanan medik dewasa ini membutuhkan sistem yang lebih efektif dan efisien, baik dalam
penggunaan waktu, tenaga maupun sarana. Dalam pengelolaan rekam medik, kenyataan masih
umumnya penggunaan rekam medik manual yang dinilai tak lagi andal menangani data medik
melahirkan ide konversi rekam medik manual kertas ke rekam medik elektronik karena efektivitas dan
efisiensinya.
Penelitian ini bertujuan menciptakan aplikasi rekam medik elektronik yang lebih dikenal
sebagai EMR (Electronic Medical Record) dari rekam medik kertas di Instalasi Rawat Inap Rumah
Sakit Umum Ananda Salatiga. Rekam medik elektronik dirancang dengan membuat form-form isian
catatan-catatan medik dalam proses perawatan pasien selama dirawat. Data-data medik ini kemudian
disimpan dalam basis data sistem dan dikelola secara digital. Setiap kali pengisian data medik pada
form-form tertentu, sistem akan menghasilkan kode yang membawa informasi khusus.
Pada akhirnya, sistem akan menghasilkan deret kode ICD (International Statistical
Classification of Diseases and Related Health Problems) dari kode-kode yang dihasilkan pada
pengisian form-form catatan medik. Deretan kode-kode ini mampu menggambarkan perkembangan
kondisi pasien dan penanganan medik yang diberikan selama perawatan. Data-data medik yang
tersimpan dapat ditampilkan kembali dalam bentuk catatan medik digital.

Utility of novel diagnostic tests for tuberculosis using human urine
No full textIncludes abstract.Includes bibliographical references.Two thirds of new TB cases in sub-Saharan Africa are HIV coinfected. HIV-TB co-infection increases the incidence of extra-pulmonary, sputum smear-negative and sputum-scarce TB. In these vulnerable patientgroups with high mortality rates, sputum-based diagnostic tools are unhelpful. Urine-based diagnostics offer an attractive, easily available alternative for rapid diagnosis. We evaluated the point-of-care urine LAM strip test (Determine TB LAM Ag test, Alere) and urine-based Xpert MTB/RIF for TB diagnosis in two patient cohorts with high HIV prevalence. A spot urine sample was collected from two cohorts of persons with suspected TB. The first cohort consisted of ambulatory primary care clinic patients suspected of having TB (group 1) whilst the second comprised hospitalised patients with suspected HIV co-infection (group 2). The urine LAM ELISA, LAM strip test and Xpert MTB/RIF were performed according to the manufacturer’s instructions. In addition, the effects of using an alternative ‘rulein’ cut-point for the urine LAM strip test and a pelleted (2-10ml) urine sample for Xpert MTB/RIF testing on diagnostic accuracy and inter-reader reliability was assessed. The diagnostic reference standard was M. tuberculosis culture positivity
