This paper presents a new Active Learning algorithm to train Radial Basis Function (RBF) Artificial Neural Networks (ANN) for model reduction problems. The new approach is based on the assumption that the unobserved training data y at input x, lies within a set F x y f x y f x ( ) : ( ) ( ) = ! ! " # where F(x) is known from experience or past simulations. The new approach finds the location of the new sample such that the worst case error between the output of the resulting RBF ANN and the bounds of the unknown data as specified by F(x) is minimized. This paper illustrates the new approach for the case when x " R1. It was found that it is possible to find a good location for the new data sample by using the suggested approach in certain cases. A comparative study was also done indicating that the new experiment design approach is a g...
The Internet is gradually gaining its popularity in Malaysian higher institutions. Today, many language teachers spend endless and fruitless hours of information surfing via the Internet but their painstaking effort sometimes ended up with information that is completely different and irrelevant. However, there it is not much evidence on the application of the Internet in Malaysian higher institutions as well as teachers' view on their Internet application in language teaching. Therefore, the aim of this research is to seek the perception of Malaysian English language teachers of higher institutions on the use of Internet in language teaching and learning, particularly in English as a Second or Foreign Language. 15 respondents who are teaching in two universities were the subjects of the research. Their computing involvement, frequency ...
Wanita usia 45 tahun keatas memasuki mas menopause dengan keluhan-keluhan yang diakibatkan defisiensi estrogen. Berkurangnya hormon estrogen akan mengalami beberapa kelainan, baik yang terjadi jangka pendek maupun jangka panjang. Keluhan yang dialami meliputi keluhan vasomotorik, keluhan traktus urogenital, keluhan konstitusional, keluhan psikiastenik dan neuretik. Keluhan yang dirasakan pada masa menopause erat kaitannya denagan karakteristik demografi dan umur saat menopause. Tujuan penelitian Mengetahui Hubungan karakteristik demografi dan umur saat menopause dengan keluhan masa menopause. Jenis penelitian yang dilakukan merupakan Explanatory Research dengan pendekatan cross sectional study. Populasi dalam penelitian ini adalah seluruh ibu-ibu anggota posyandu usia lanjut di Kelurahan Putussibau Kota Kecamatan Putussibau Kabupaten ...
Analisis varians satu hala telah dijalankan secara terperinci terhadap 24 keputusan modal daripada lapan sampel granit yang dikutip dari sebahagian satu keratan jalan di Lebuhraya Kuala Lumpur–Karak. Singkapan kelihatan seperti seragam dari segi tekstur dan kandungan mineralnya. Penyampelan dipastikan rawak dengan mengikut reka bentuk penyampelan multitahap. Tiap sampel dibuatkan tiga keratan nipis atau subsampel dan kandungan modalnya didapati dengan kiraan titik di bawah mikroskop. Ujian F dijalankan terhadap keputusan analisis varians untuk mengetahui secara kuantitatif darjah keyakinan kandungan modal tiap mineral komponen. Antara lima mineral yang diuji, dua, iaitu feldspar alkali dan muskovit, didapati tidak homogen pada had keyakinan 5%. Keputusan tersebut mungkin disebabkan oleh saiz feldspar (terkasar) dan bentuk muskovit (l...
Calcium carbonate powder used as filler is produced from limestone. It is extremely difficult to define the limits of this mineral category. Its definition depends more on its uses than on its physical or chemical properties. Calcium carbonate filler comes in two forms: ground and light. Ground calcium carbonate is a low quality product and is much cheaper than light calcium carbonate. It has been widely used in several industries. For several purposes. Calcium carbonate filler must have high brightness and vary in size from nominal 325 mesh to submicron material. For plastics and pain industry, they must have low oil absorption and ease of dispersion. Quantitative analysis of the market is difficult to compile due to lack of statistics in the field. However, the polymer and paint industry are the largest consumer of white carbonate fi...
A function generator is widely used for experimental work and testing to generate various types of waveform (sine, square, triangle, etc) with a particular frequency bandwidth. One of its applications is in generating waveform for the ECT (Electrical Capacitance Tomography) system. ECT is used to retrieve the details of material in a flow system. An economical PC Controlled Function Generator was designed for the use of waveform generating in ECT. For the ECT system, high accuracy and frequency waveforms are needed. Three basic waveforms are required; the sine wave, square wave, and triangular wave. The objective is to build a function generator which is capable of generating high accuracy waveforms with acceptable distortion and stability. An interfacing system between a PC and the function generator was also selected and developed w...
Salah satu uasaha pemerintah untuk meningkatkan masyarakat agar dapat melaksanakan hidup sehat, dilaksanakan program Posyandu, dengan tujuan untuk menurunkan angka kematian bayi dan balita serta menurunkan angka kelahiran. Cakupan partisipasi masyarakat pengguna posyandu (D/S) di Deesa Tambaharjo 26,28 % sedangkan target cakupan D/S Jawa Tengah 60 %. Cakupan yang rendah dikhawatirkan informasi atau pengetahuan tidak mencapai semua sasaran sehingga tujuan unutk merubah perilaku unutk hidup sehat sulit dicapai. Tujuan penulisan untuk mengetahui faktor-faktor yang berhubugan dengan ketidakhadiran balita di posyandu. Penelitian dilakukan dengan wawancara pada 168 responden, responden yaitu ibu yang mempunyai balita usia antara 10 bulan sampai dengan 60 bulan di Desa Tambaharjo. Pengolahan data dilakukan dengan bantuan komputer dengan p...
This research initiates the connection between formal language theory and the study of informational macromolecules. The modelling of a biological splicing system has been done mathematically through formal language theory, which is a branch of applied group theory and theoretical computer science. The accuracy of how a splicing works has been verified through the corresponding biological splicing system. In this research, different kinds of languages that result from the action of restriction enzymes on strings of DNA molecules have been studied. Examples of strictly locally testable languages are given. Besides, some theorems related to different combination of restriction enzymes in a strictly locally testable language are presented. A language is local if every string of a certain length is a constant relative to it. Som...
Pelayanan rumah sakit pada saat ini merupakan bentuk upaya pelayanan kesehatan yang bersifat sosioekonomi, mengelola rumah sakit secara bisnis dan ekonomis tanpa melupakan fungsi sosialnya, artinya suatu usaha yang walau bersifat sosial namun diusahakan agar bisa mendapat surplus keuangan dengan cara pengelolaan yang profesional dengan memperhatikan prinsipprinsip ekonomi. Tujuannya adalah membangun rumah sakit yang mandiri dalam pembiayaan melalui pengelolaan langsung dana yang diperoleh dari berbagai sumber di rumah sakit. 1,2 Untuk dapat melaksanakan tugas sesuai SK Menteri Kesehatan RI No 983/Menkes/SK/XI/92 tentang Pedoman Organisasi Rumah Sakit Umum, maka rumah sakit harus menjalankan beberapa fungsi, satu diantaranya adalah fungsi menyelenggarakan pelayanan penunjang medik dan non medik.Pelayanan penunjang medik meliputi pelayan...
Various atomic ratios of metal doped TiO2 were prepared using Mn2+, Fe2+, Fe3+, Cu2+, Zn2+, Cu2+ co-doped with Fe3+ and Zn2+ co-doped with Fe3+. Photocatalytic degradation of CH2Cl2, CHCl3 and CCl4 using various atomic ratios of metal doped TiO2 showed the existence of optimum dopant ratio, which indicates the dependency of photoactivity of doped TiO2 on dopant concentration. Besides, dopants can affect the photoactivity of doped TiO2 by acting as hole/electron traps or as recombination centres. Using doped catalysts such as Fe2+/TiO2, Fe3+/TiO2, Cu2+/TiO2, Zn2+/TiO2, Cu2+/Fe3+/TiO2 and Zn2+/Fe3+/TiO2 gave higher degradation of VOCs than pure TiO2. However, adding of Mn2+ was detrimental to the process. The rate of degradation of the studied chlorinated hydrocarbons follows the order: CHCl3 > CH2Cl2 > CCl4. This indicates different VOC...
