Full text linkRueh Rong- Rong merupakan karya tari yang berpijak dari Upacara Adat Belian khas Kabupaten Penajam Paser Utara. Kata Rueh memiliki arti dua dalam bahasa dayak Lawangan yang menunjukan bahwa ada alam atas dan bahwa lalu ada penguasa atas dan penguasa bawah sedangkan kata Rong- Rong terinspirasi dari suara gelang yang mengehasilkan suara seperti Rong, Rong berarti juga Gelang. Kepercayaan suku dayak ialah animism yang menurut pandangan keagamaan itu semua makhluk hidup maupun mati mempunyai jiwa. Masyarakat Kabupaten Penajam Paser Utara sampai saat ini masih melakukan ritual persembahan terhadap kedua penguasa pencipta dan pengganggu atau atas dan bawah dengan cara melakukan upacara adat Belian. Kata Belian secara etimologi Lietn: tuing atau betuhing yang sebenarnya mengandung arti berpantang atau tabu. Karya ini menitik beratkan pada pemimpin upacara adat belian yang berjenis kelamin wanita dalam upacara adat belian yang ditunjukan untuk keselamatan masyarakat di daerah Penajam Paser Utara, Kalimantan Timur. Dalam Upacara adat belian ada satu benda yang menjadi syarat utama adanya yaitu Gelang (Gitang/ Rong). Pada karya tari Rueh Rong- Rongmenggunakan delapan penari wanita. Penyajian iringan musik ditabuh secara langsung dengan menggunakan instrumen yang mengutamakan instrumen asli Kalimantan. Karya ini disajikan dengan tipe studi dramatik dan dibagi menjadi empat segmen
Error probability and capacity analysis of generalised pre-coding aided spatial modulation
Full text linkThe recently proposed multiple input multiple output (MIMO) transmission scheme termed as generalized pre-coding aided spatial modulation (GPSM) is analyzed, where the key idea is that a particular subset of receive antennas is activated and the specific activation pattern itself conveys useful implicit information. We provide the upper bound of both the symbol error ratio (SER) and bit error ratio (BER) expression of the GPSM scheme of a low-complexity decoupled detector. Furthermore, the corresponding discrete-input continuous-output memoryless channel (DCMC) capacity as well as the achievable rate is quantified. Our analytical SER and BER upper bound expressions are confirmed to be tight by our numerical results. We also show that our GPSM scheme constitutes a flexible MIMO arrangement and there is always a beneficial configuration for our GPSM scheme that offers the same bandwidth efficiency as that of its conventional MIMO counterpart at a lower signal to noise ratio (SNR) per bit
Generalised pre-coding aided spatial modulation
Full text linkA new Multiple Input Multiple Output (MIMO) transmission scheme termed as Generalised Pre-coding aided Spatial Modulation (GPSM) is proposed, where the key idea is that a particular subset of receive antennas is activated and the activation pattern itself conveys useful information. This is in contrast to the previously proposed Spatial Modulation (SM) schemes, which operated by activating a specific subset of transmit antennas. We provide both analytical and numerical results characterizing the GPSM scheme proposed for both conventional as well as for large-dimensional MIMO configurations subject to both realistic imperfect Channel State Information at the Transmitter (CSIT) and to the low-rank approximation invoked for large-dimensional MIMO configurations. We also design a so-called reinforcement matrix for attaining substantial performance improvements for our proposed GPSM scheme. Our investigations show that the GPSM scheme constitutes a flexible alternative to the state-of-the-art MIMO transmission schemes, especially because it is capable of achieving a high throughput. Moreover, the benefits of mapping information to the spatial domain rather than relying on conventional modulation has substantial benefits in the medium to high Signal to Noise Ratio (SNR) region. Quantitatively, GPSM is capable of supporting the same throughput as the conventional full-multiplexing gain based MIMO arrangements at an SNR gain of about 1dB at the same receiver complexity. Furthermore, the reinforcement matrix aided GPSM scheme attains a further 3-4dB performance improvement as compared to the conventional GPSM scheme

Energy pattern aided simultaneous wireless information and power transfer
Full text linkIn echoing Varshney's seminal concept of jointly transmitting information and energy, we propose the concept of an energy pattern aided Simultaneous Wireless Information and Power Transfer (SWIPT) system, where in addition to power transfer, information is conveyed both by the specific Receive Antenna (RA) indices to which the power is delivered as well as by the particular intensity of the power assigned to that particular RA pattern. By embedding information into energy patterns rather than imposing it by modulating classic radio waveforms, our proposed solution is capable of operating both in an integrated receiver mode and in a power-split mode, while relying on a low-complexity two-stage non-coherent detection algorithm. Both our analysis and simulations show that our energy pattern aided SWIPT system exhibits a beneficial immunity to any potential performance degradation imposed by power-conversion. Moreover, the achievable rate versus power conversion trade-off bounds are characterized, demonstrating that our proposed energy pattern aided SWIPT system leads to a beneficial wireless information and power transfer convergence

Multiple Source Cooperation: From Code Division Multiplexing To Variable-Rate Network Coding
No full textMultiple-source cooperation techniques, including conventional code-division multiplexing (CDM) and classic network coding (CNC), are investigated. We adopt a soft sum - product decoding algorithm for the CNC technique to efficiently process a large number of information streams and propose a flexible variable-rate network coding (VNC) technique, which is capable of attaining a near-optimum performance. Quantitatively, the proposed VNC method is capable of operating within 1 dB from the outage capacity of the quasi-static Rayleigh fading channel. The iterative decoding convergence of the multiple-source computation methods is analyzed with the aid of extrinsic information transfer charts
Bisakah Struktur Rong-rongan Rumah Joglo Hanya Mengandalkan "SANTEN"?
Full text link* Tulisan ini membahas struktur bangunan rumah trdisional Jawa “Joglo”. Penelitian penulis diawali dari penelitaian Prihatmaji (2007) tentang perilaku rumah tradisional jawa “Joglo” terhadap gempa. Dalam kesimpulannya dinyatakan bahwa struktur rumah Joglo aman untuk wilayah gempa 3, apabila sistem tumpuan dibuat jepit. Tujuan penelitian ini adalah membuat rancangan model struktur eksperimen yang: pertama mengambil bentuk struktur dan kondisi tumpuan sama dengan rong-rongan asli, dan kedua diharapkan mempunyai kekakuan lateral lebih besar dibandingkan dengan model struktur rong-rongan asli tersebut. Stabilitas dan kekakuan lateral model struktur rong-rongan asli mengandalkan pada sistem sambungan kaku antara saka-sunduk/kili, sedangkan stabilitas dan kekakuan lateral model struktur eksperimen mengandalkan pada “SANTEN”. Sistem sambungan saka-sunduk/kili pada model struktur eksperimen ditetapkan sendi sehingga stabilitas dan kekakuan lateral struktur benar-benar mengandalkan pada “SANTEN” saja. Hasil simulasi empat buah model struktur dengan software ETABS menunjukkan bahwa model-model struktur eksperimen dapat mempunyai kekakuan minimal sama, atau lebih besar dibandingkan dengan model struktur rong-rongan asli.

Carbon source/sink function of a subtropical, eutrophic lake determined from an overall mass balance and a gas exchange and carbon burial balance
No full textAlthough studies on carbon burial in lake sediments have shown that lakes are disproportionately important carbon sinks, many studies on gaseous carbon exchange across the water–air interface have demonstrated that lakes are supersaturated with CO2 and CH4 causing a net release of CO2 and CH4 to the atmosphere. In order to more accurately estimate the net carbon source/sink function of lake ecosystems, a more comprehensive carbon budget is needed, especially for gaseous carbon exchange across the water–air interface. Using two methods, overall mass balance and gas exchange and carbon burial balance, we assessed the carbon source/sink function of Lake Donghu, a subtropical, eutrophic lake, from April 2003 to March 2004. With the overall mass balance calculations, total carbon input was 14 905 t, total carbon output was 4950 t, and net carbon budget was +9955 t, suggesting that Lake Donghu was a great carbon sink. For the gas exchange and carbon burial balance, gaseous carbon (CO2 and CH4) emission across the water–air interface totaled 752 t while carbon burial in the lake sediment was 9477 t. The ratio of carbon emission into the atmosphere to carbon burial into the sediment was only 0.08. This low ratio indicates that Lake Donghu is a great carbon sink. Results showed good agreement between the two methods with both showing Lake Donghu to be a great carbon sink. This results from the high primary production of Lake Donghu, substantive allochthonous carbon inputs and intensive anthropogenic activity. Gaseous carbon emission accounted for about 15% of the total carbon output, indicating that the total output would be underestimated without including gaseous carbon exchange.Due to high primary production, substantive allochthonous carbon inputs and intensive anthropogenic acitivity, subtropical, eutrophic Lake Donghu is a great carbon sink.<br/
