Implementasi Media Animasi Komputer dalam Pembelajaran Sistem Respirasi dan Sistem Ekskresi di SMA Ampera Kota Sorong

Penggunaan media animasi komputer masih jarang digunakan dalam proses pembelajaran, sehingga perlu dilakukan pembelajaran biologi dengan menggunakan media animasi komputer. Penelitian ini bertujuan untuk mengetahui keefektifan implementasi media animasi komputer dalam pembelajaran Sistem Respirasi dan Sistem Ekskresi di SMA Ampera Kota Sorong. Metode yang digunakan dalam penelitian ini adalah quasi eksperimen, sampel diambil secara purposive sampling. Instrumen yang digunakan adalah tes tertulis dan angket hasil data tes tertulis untuk materi non perlakuan terhadap materi dengan perlakuan di SMA Ampera Kota Sorong diperoleh nilai signifikasi 0,11 > 0,005 H0 diperoleh nilai hasil belajar siswa pada pembelajaran non media dan pembelajaran dengan media sama. Hasil angket materi non perlakuan terhadap materi dengan perlakuan diuji t hitung 60,939 > t tabel 2,203951 H1 diterima (berbeda) artinya di SMA Ampera Kota Sorong motivasi belajar siswa untuk materi dengan perlakuan lebih baik. Hasil observasi di SMA Ampera Kota Sorong,aktivitas siswa masing-masing lebih baik pada PBM untuk kedua materi. Secara umum kesimpulan hasil penelitian yakni penggunaan media animasi komputer dalam pembelajaran sistem respirasi dan sistem ekskresi tidak efektif pada ranah kognitif sedangkan efektif pada ranah afektif dan psikomotor

Ubiquitous Internet in an integrated satellite-terrestrial environment: The SUITED solution

yesThe current Internet architecture appears to not be particularly suited to addressing the emerging needs of new classes of users who wish to gain access to multimedia services made available by ISPs, regardless of their location, while in motion and with a guaranteed level of quality. One of the main objectives of so-called nextgeneration systems is to overcome the limitations of today¿s available Internet by adopting an approach based on the integration of different mobile and fixed networks. The SUITED project moves in this direction since it aims at contributing to the design and deployment of the global mobile broadband system (GMBS), a unique satellite/terrestrial infrastructure ensuring nomadic users access to Internet services with a negotiated QoS. A description of the main features of the GMBS architecture, characterized by the integration of a multisegment access network with a federated ISP network is given in this article. The GMBS multimode terminal is schematically described, and an overview of the so-called QoS-aware mobility management scheme, devised for such a heterogeneous scenario,is provided

Measurement of Photon Statistics with Live Photoreceptor Cells

We analyzed the electrophysiological response of an isolated rod photoreceptor of Xenopus laevis under stimulation by coherent and pseudo-thermal light sources. Using the suction electrode technique for single cell recordings and a fiber optics setup for light delivery allowed measurements of the major statistical characteristics of the rod response. The results indicate differences in average responses of rod cells to coherent and pseudo-thermal light of the same intensity and also differences in signal-to-noise ratios and second order intensity correlation functions. These findings should be relevant for interdisciplinary studies seeking applications of quantum optics in biology.Comment: 6 pages, 7 figure

Parallel solution of high-order numerical schemes for solving incompressible flows

A new parallel numerical scheme for solving incompressible steady-state flows is presented. The algorithm uses a finite-difference approach to solving the Navier-Stokes equations. The algorithms are scalable and expandable. They may be used with only two processors or with as many processors as are available. The code is general and expandable. Any size grid may be used. Four processors of the NASA LeRC Hypercluster were used to solve for steady-state flow in a driven square cavity. The Hypercluster was configured in a distributed-memory, hypercube-like architecture. By using a 50-by-50 finite-difference solution grid, an efficiency of 74 percent (a speedup of 2.96) was obtained

Performance Analysis of Satellite Payload Architectures for Mobile Services

YesThis paper is concerned with the effects on the network performance of moving parts of what is considered traditionally to belong to the ground segment to on board the satellite. Initially, an overview of geostationary satellite communication systems and payload technology is presented, followed by a description of the network architecture and protocols that are the basis of the simulation models. The results obtained from this testbed are presented before concluding with a discussion of the results obtained

4-(2-Methoxyphenyl)piperazin-1-ium 6-chloro-5-isopropyl-2,4-dioxopyrimidin-1-ide

In the cation of the title salt, C11H17N2O+.C7H8ClN2O2 -, the piperazine ring adopts a distorted chair conformation and contains a positively charged N atom with quaternary character. Its mean plane makes a dihedral angle of 42.36 (8)� with the phenyl ring of its 2-methoxyphenyl substituent. The 2,4-dioxopyrimidin-1-ide anion is generated by deprotonation of the N atom at the 1-position of the pyrimidinedione ring. Intramolecular C—H...O hydrogen bonds generate S(6) ring motifs in both the cation and the anion. In the crystal, N—H...O, N—H...N and C—H...O hydrogen bonds are also observed, resulting in a twodimensional network parallel to the ab plane. The crystal stability is further consolidated by weak C—H...n interactions

Stochastic approach for active and reactive power management in distribution networks

YesIn this paper, a stochastic method is proposed to assess the amount of active and reactive power that can be injected/absorbed to/from grid within a distribution market environment. Also, the impact of wind power penetration on the reactive and active distribution-locational marginal prices is investigated. Market-based active and reactive optimal power flow is used to maximize the social welfare considering uncertainties related to wind speed and load demand. The uncertainties are modeled by Scenario-based approach. The proposed model is examined with 16-bus UK generic distribution system.Supported by the Higher Education Ministry of Iraqi government
