Simulated Annealing for Location Area Planning in Cellular networks
Full text linkLA planning in cellular network is useful for minimizing location management
cost in GSM network. In fact, size of LA can be optimized to create a balance
between the LA update rate and expected paging rate within LA. To get optimal
result for LA planning in cellular network simulated annealing algorithm is
used. Simulated annealing give optimal results in acceptable run-time.Comment: 7 Pages, JGraph-Hoc Journa
Human-centric light sensing and estimation from RGBD images: the invisible light switch
Get PDFLighting design in indoor environments is of primary importance for at least two reasons: 1) people should perceive an adequate light; 2) an effective lighting design means consistent energy saving. We present the Invisible Light Switch (ILS) to address both aspects. ILS dynamically adjusts the room illumination level to save energy while maintaining constant the light level perception of the users. So the energy saving is invisible to them. Our proposed ILS leverages a radiosity model to estimate the light level which is perceived by a person within an indoor environment, taking into account the person position and her/his viewing frustum (head pose). ILS may therefore dim those luminaires, which are not seen by the user, resulting in an effective energy saving, especially in large open offices (where light may otherwise be ON everywhere for a single person). To quantify the system performance, we have collected a new dataset where people wear luxmeter devices while working in office rooms. The luxmeters measure the amount of light (in Lux) reaching the people gaze, which we consider a proxy to their illumination level perception. Our initial results are promising: in a room with 8 LED luminaires, the energy consumption in a day may be reduced from 18585 to 6206 watts with ILS (currently needing 1560 watts for operations). While doing so, the drop in perceived lighting decreases by just 200 lux, a value considered negligible when the original illumination level is above 1200 lux, as is normally the case in offices
Pengembangan Kurikulum Lptk (Penyiapan Calon Guru Pai) Berbasis Kkni
Full text linkSetelah program sertifikasi guru dan dosen dilakukan oleh pemerintah dan ternyata kurang signifikan terhadap peningkatan kualitas, kini harapan memiliki guru harapan masa depan sangat dinanti dari kinerja Lembaga Pendidikan Tenaga Kependidikan (LPTK) tak terkecuali Lembaga Pendidikan Tenaga Pendidikan Islam (LPTKI). Sebagai sebuah institusi yang bertugas menyiapkan lulusan calon tenaga pendidik, LPTKI mempunyai peran sentral dalam penyediaan sumber daya manusia yang berkualitas. Satu sisi LPTKI harus mampu mencetak calon guru agama yang profesional, sisi lain guru agama sebagai tenaga pendidik lulusan LPTKI dituntut mampu nendidik secara profesional pula untuk menghasilkan lulusan yang memiliki karakter tinggi berbasis kekuatan iman dan taqwa.Seiring dengan Perubahan zaman yang cepat, serta persaingan pasar tenaga kerja yang sangat ketat, maka LPTKI dituntut melakukan pembaharuan di segala aspek pendidikan khususnya pembaharuan kurikulum. Beberapa kebijakan pemerintah telah diberlakukan untuk meningkatkan mutu guru Indonesia antara lain: Pertama, Undang-undang nomor 14 tahun 2005 tentang Guru dan Dosen (UUGD) yang bertujuan untuk meningkatkan martabat dan peran guru sebagai agen pembelajaran. Dalam UUGD dinyatakan bahwa guru adalah pendidik profesional. Kedua, terbitnya Peraturan Pemerintah nomor 19 tahun 2005 tentang Standar Nasional Pendidikan (SNP) yang memuat standarisasi penyelenggaraan sistem pendidikan tak terkecuali LPTK/LPTKI. Ketiga, Peraturan Presiden Republik Indonesia nomor 8 tahun 2012 tentang Kerangka Kualifikasi Nasional Indonesia (KKNI) yang mencoba mengintegrasikan lembaga pendidikan dengan bidang pelatihan kerja dan dunia kerja untuk mendapatkan kompetensi yang tinggi guna memenuhi kebutuhan dunia kerja.Dengan diberlakukannya KKNI, maka kurikulum pendidikan LPTKI memerrlukan upaya-upaya pembaharuan yang tepat agar pembelajaran yang ditempuh merupakan model yang efektif dalam memenuhi tuntutan mutu pendidikan guru

Integrasi Unit USAha Simpan Pinjam (Usp) Milik Koperasi Ke Dalam Bank Koperasi (Analisis Potensi Dan Penguatan Finansial Koperasi Menuju Kemandirian)
Full text linkAs a business entity, Cooperation still faces fundamental problems such as lacking of financial support institutions that fully owned by Cooperation. Nowadays, there are financial institutions dealing with Cooperation such as BUKOPIN. However, the financial institution is not fully owned by Cooperation. Although the Bank was initiated by Cooperation, the institution have been transferred to be a private Bank. Therefore, it is important to initiate a financial institution owned by Cooperation by integrating units of savings and loans into a Cooperation Bank. If it can be done, then the bargaining position of Cooperation in the financial field will be stronger, and pride of Cooperation can be maintained
Links Between Physical and Mental Health: Assessment of Therapeutic Riding’s Effect on Children with Special Needs
Get PDFThis observational study examined the effect of therapeutic riding (TR) on four domains, physical skills, positive values, social skills, and self-identity in children with special needs. Participants were recruited from SARI Therapeutic Riding and were divided, based on observation, into more or less severe diagnosis categories. It was predicted that children with less severe diagnosis would show more of an increase on the four domains, especially physical skills due to TR. Participants were observed using an observational checklist at pre- and post-riding lessons. Results showed non-significant differences in all four domains, however, there was a tendency for scores to increase from pre- to post-observations. Furthermore, statistically significant overall effects were found between sessions, for diagnoses, in all four domains, p \u3c .006. It can be concluded that TR has some beneficial effects on the positive values, social skills, self-identity, and physical skills of children with special needs, although not significant
Free-radical chain reactions of organic mercury and tin compounds
Get PDFAlkylmercury halides (RHgX, R = n-butyl, n-hexyl, (DELTA)(\u273)-butenyl, (DELTA)(\u275)-hexenyl, isopropyl, cyclohexyl, cyclopentylcarbinyl and 7-norbornyl) rapidly react with PhYYPh (Y = S, Se and Te), p-MeC(,6)H(,4)SO(,2)SePh, PhSO(,2)Cl, PhSH and BrCCl(,3) under sunlamp irradiation to give RYPh, RCl, RH and RBr, respectively. The reaction is completely inhibited by di-tert-butyl nitroxide, does not occur in the dark and yields a mixture of cyclopentylcarbinyl and (DELTA)(\u275)-hexenyl products from the (DELTA)(\u275)-hexenylmercurial. The reaction is believed to proceed via a radical chain mechanism involving R(.) and Hg(III) intermediates. The alkyl radical (R(.)) undergoes S(,H)(\u272) or atom transfer reactions with the substrate and the resulting radical (PhY(.), PhSO(,2)(.) or (.)CCl(,3)) reacts with RHgX to form the Hg(III) intermediate which then eliminates R(.). A similar mechanism is proposed for the reaction of dialkylmercurials (R(,2)Hg, R = n-butyl, isobutyl and (DELTA)(\u275)-hexenyl) with PhSSPh and PhSeSePh. However, benzylmercurials (PhCH(,2)HgQ, Q = Cl and PhCH(,2)) react with phenyl dichalcogenide differently from other alkylmercurials, in that bibenzyl is formed in a chain reaction. Bibenzyl is also the product of the photostimulated chain decomposition of PhCh(,2)HgQ (Q = PhCH(,2) and PhS). Evidence is presented that the reaction of benzylmercurials proceeds by a free radical chain mechanism involving S(,H)(\u272) attack of the benzyl radical at the benzyl mercury bond;Tri-n-butyl-1-alkenyltin compounds containing a (beta)-phenyl substituent, PhCH=CHSnBu(,3) and Ph(,2)C=CHSnBu(,3), undergo a photostimulated reaction with 2(DEGREES)- or 3(DEGREES)-alkylmercurials to give PhCH=CHR and Ph(,2)C=CHR, Bu(,3)SnCl and Hg(0). The reaction was established to proceed via a radical chain process involving (alpha)-addition of the alkyl radical followed by (beta)-elimination of Bu(,3)Sn(.) and electron transfer from the tin-centered radical to the alkylmercurials. The reaction has been successfully extended to other (beta)-substituted styrenes, PhCH=CHQ (Q = I, PhSO(,2), HgCl and PhS) where Q(.) can be reacted with RHgX to generate R(.). In addition, PhCH=CHSnBu(,3) reacts with CCl(,3)Z (Z = Cl, Br and SO(,2)Cl) under UV irradiation to give exclusively PhCH=CHCCl(,3). Similarly, 1-alkenyltin derivatives with or without a (beta)-phenyl substituent, react with sulfur-centered radicals (PhS(.), PhCH(,2)S(.), PhSO(,2)S(.) and p-MePhSO(,2)(.)) derived from the reaction of Bu(,3)Sn(.) with PhSSPh, PhCH(,2)SSCH(,2)Ph, PhSO(,2)Cl or p-MeC(,6)H(,4)SO(,2)SePh to give the corresponding sulfides and sulfones in excellent yields
