On the Capacity Region of the Deterministic Y-Channel with Common and Private Messages

In multi user Gaussian relay networks, it is desirable to transmit private information to each user as well as common information to all of them. However, the capacity region of such networks with both kinds of information is not easy to characterize. The prior art used simple linear deterministic models in order to approximate the capacities of these Gaussian networks. This paper discusses the capacity region of the deterministic Y-channel with private and common messages. In this channel, each user aims at delivering two private messages to the other two users in addition to a common message directed towards both of them. As there is no direct link between the users, all messages must pass through an intermediate relay. We present outer-bounds on the rate region using genie aided and cut-set bounds. Then, we develop a greedy scheme to define an achievable region and show that at a certain number of levels at the relay, our achievable region coincides with the upper bound. Finally, we argue that these bounds for this setup are not sufficient to characterize the capacity region.Comment: 4 figures, 7 page

Analisis Kejadian Luar Biasa (KLB) Demam Berdarah Dengue (DBD) Di Wilayah Puskesmas Rawasari Kota Jambi Bulan Agustus 2011

Telah terjadi Kejadian Luar Biasa (KLB) DBD di Kota Jambi berdasarkan laporan wabah/KLB (W1) dari Dinas Kesehatan Propinsi Jambi Agustus tahun 2011. Jumlah kasus yang dilaporkan sebanyak 261 orang dan kematian sebanyak 8 orang dengan Case Fatality Rate (CFR) sebesar 3,1%. Menindaklanjuti laporan dari Dinas Kesehatan Propinsi Jambi tersebut maka tim peneliti Loka Litbang P2B2 Baturaja melakukan survey dengan tujuan untuk mengidentifikasi kepadatan jentik nyamuk Aedes sp., penyebaran kasus DBD, dan efektifitas kegiatan yang telah dilakukan oleh Dinas Kesehatan, Puskesmas maupun masyarakat. Hasil survey jentik terhadap 107 rumah ditemukan sebanyak 13 rumah (12,1%) ditemukan adanya jentik, 7,9% tempat penampungan air (kontainer) ditemukan adanya jentik dan angka bebas jentik (ABJ) sebesar 87,9. Jentik Aedes sp. lebih banyak ditemukan pada kontainer yang berada di dalam rumah dibanding di luar rumah dan dalam kondisi terbuka dibanding yang tertutup. Kepadatan jentik berdasarkan parameter density figure di wilayah Kelurahan Mayang termasuk dalam kategori sedang. Jumlah rumah penderita yang diperiksa sebanyak 25 rumah dan 3 rumah diantaranya ditemukan jentik Aedes sp. Berdasarkan hasil survey yang telah dilakukan tim peneliti Loka Litbang P2B2 Baturaja maka disarankan agar kegiatan abatisasi massal sebaiknya disertai dengan kegiatan Pemberansan Sarang Nyamuk (PSN) yang kegiatannya juga membersihkan tempat-tempat tersembunyi yang dapat dijadikan sebagai tempat untuk berkembangbiak bagi nyamuk Aedes sp. seperti membersihkan kulkas, dispenser, pot bunga dan tempat-tempat tersembunyi lainnya. Rumah penderita serta rumah di sekitar penderita perlu mendapat perhatian yang lebih intensif untuk menghilangkan jentik Aedes sp. di rumah penderita agar tidak terjadi penularan lebih lanjut

Hidden Curriculum Pada Sistem Pendidikan Sekolah Tinggi Agama Islam Negeri (Stain) Purwokerto Tahun 2013

Hidden curriculum refers to all matters influncing the teaching and learning process. This means that hidden curriculum contains practices and educational results not explicitly stated in the written curriculum.This is a field research conducting in STAIN (State College on Islamic Studies) of Purwokerto in 2013. This research used sociological and antrophological approach. The other aproach used in this research was fenomenology and symbolic interactionalism. This is a grounded research in which all analysis were based on data and factsfound in the field. Data were collected through observation, interview, and documentation. Data were analyzed with descriptive qualitative analysis. Hidden curriculum results from the practice of lecturing in which some lecturers do not refer to the curse outline. Hidden curriculum influnced by ideal dimension can be seen from thewill to improve the institution and competency of lecturers andstudents. Behavioral dimension is not influenced by ideal dimension, but it is a cultural expression which is relatively common and spontaneous. Materials of hidden curriculum which are relatively unplanned in the ideal dimension are those which are already customized and out of awareness. Hidden Curriculum menunjuk kepada segala sesuatu yangdapat berpengaruh di dalam berlangsungnya proses pengajaran dan pendidikan yang mungkin dapat meningkatkan atau mendorong atau bahkan melemahkan USAha pencapaian tujuan pendidikan. Dengan kata lain hidden curriculum menunjuk pada praktek dan hasil pendidikan yang tidak diuraikan dalam kurikulum terprogram atau petunjuk kurikulum kebijakan lembaga pendidikan. Penelitian ini merupakan penelitian lapangan (field research). Dengan tempat penelitian di Sekolah Tinggi Agama Islam Negeri Purwokerto Tahun 2013. Pendekatan yang digunakan dalam penelitian ini yaitu pendekatan sosiologis–antropologis.Pendekatan lainya yang bisa dikembangkan yaitu pendekatan fenomenologis-interaksi simbol. Pendekatan ini berasumsi bahwa pengalaman manusia ditengahi oleh penafsiran.Penelitian ini bersifat grounded research dengan mendasarkan semua analisa pada data dan fakta yang diperoleh di lapangan. Metode pengumpulan datanya adalah metode observasi,metode wawancara, metode dokumentasi. Metode analisa data yang digunakan analisis data kualitatif4, dengan teknik deskriptifanatilis Hidden curriculum dalam perkuliahan terjadi karena beberapa dosen masih menggunakan cara perkuliahan tanpa mengacu padasilabus Satuan Acara Perkuliahan. Hidden curriculum yang digerakkan oleh dimensi ide, dapat dilihat dari keinginan pengembangan kapasitas kelembagaan dan kemampuan dosen dan mahasiswa. Dimensi perilaku yang tidak digerakkan oleh dimensi ide, tapi sabagai ekspresi cultural yang relatif telah membudaya dan tidak disadari. Bentuk hidden curriculum pada dimensi material yang relative tidak direncanakan dalam dimensi ide adalah bentuk material yang telah mentradisi danrelative tidak disadari

Open Source System as Innovation in Organizations: a Managerial Perspective on Its Adoption

This study identifies the factors that have a direct effect on a manager's decision towards Open Source System (OSS) enterprise system adoption in Malaysia. Using the Technology-Organization-Environment (TOE) framework, the research is initiated by inviting the managers in Malaysian organizations who implemented OSS. A survey was conducted via online OSS social communities and by sending emails to shortlisted public. A total of 124 managers from 124 organizations responded to the survey and the results showed that four out of six factors were found significant in this study. In the technological context, ‘perceived relative advantage’, ‘perceived compatibility and trialability’ and ‘perceived complexity’ factors were found significant in the OSS adoption. In the organizational context, ‘management support, knowledge and expertise’ was identified as the adoption factor. Two factors in the environmental context that was not supported were the ‘technology skills and services’ and ‘platform long term viability’ although previous studies suggested otherwise

Enhancement of Secrecy of Block Ciphered Systems by Deliberate Noise

This paper considers the problem of end-end security enhancement by resorting to deliberate noise injected in ciphertexts. The main goal is to generate a degraded wiretap channel in application layer over which Wyner-type secrecy encoding is invoked to deliver additional secure information. More specifically, we study secrecy enhancement of DES block cipher working in cipher feedback model (CFB) when adjustable and intentional noise is introduced into encrypted data in application layer. A verification strategy in exhaustive search step of linear attack is designed to allow Eve to mount a successful attack in the noisy environment. Thus, a controllable wiretap channel is created over multiple frames by taking advantage of errors in Eve's cryptanalysis, whose secrecy capacity is found for the case of known channel states at receivers. As a result, additional secure information can be delivered by performing Wyner type secrecy encoding over super-frames ahead of encryption, namely, our proposed secrecy encoding-then-encryption scheme. These secrecy bits could be taken as symmetric keys for upcoming frames. Numerical results indicate that a sufficiently large secrecy rate can be achieved by selective noise addition.Comment: 11 pages, 8 figures, journa

Penentuan Jenis Nyamuk Mansoniasebagai Tersangka Vektor Filariasis Brugia Malayi dan Hewan Zoonosis di Kabupaten Muaro Jambi

Filariasis merupakan penyakit yang tidak mudah menular. Filariasis adalah penyakit yang ditularkan oleh nyamuk sebagai vector. Jenis nyamuk yang dapat berperan sebagai vector filariasis dipengaruhi oleh jenis cacing penyebab filaria. Brugia spp. umumnya ditularkan oleh nyamuk Mansonia spp dan Anopheles spp. Vektor dan hewan zoonosis merupakan salah satu factor yang dapat perlu mendapat perhatian dalam pengendalian filariasis. Penelitian terhadap vector dan hewan zoonosis telah dilakukan di Kabupaten Muaro Jambi untuk mengidentifikasi bionomik vektor dan kemungkinan adanya hewan zoonosis yang berperan sebagai penular filariasis. Desain penelitian adalah observasi, yaitu dengan melakukan penangkapan nyamuk dan pemeriksaan darah terhadap kucing. Jumlah kucing yang diperiksa sebanyak 18 ekor. Kucing yang positif microfilaria sebanyak 1 ekor. Jumlah nyamuk Mansonia spp. tertangkap sebanyak 1,167 ekor yang terdiri dari 6 species. Spesies nyamuk tertangkap paling banyak adalah Mansonia uniformis sebanyak 1.010 ekor dengan angka kekerapan 1,0. Berdasarkan hasil tersebut, maka diperlukan peran serta masyarakat untuk mengurangi kepadatan nyamuk dengan membersihkan genangan air dan mencegah gigitan nyamuk.
