A new approach to dynamic bandwidth allocation in Quality of Service networks: Performance and bounds
No full textEfficient dynamic resource provisioning algorithms are necessary to the development and automation of Quality of Service (QoS) networks. The main goal of these algorithms is to offer services that satisfy the QoS requirements of individual users while guaranteeing at the same time an efficient utilization of network resources.
In this paper we introduce a new service model that provides per-flow bandwidth guarantees, where users subscribe for a guaranteed rate; moreover, the network periodically individuates unused bandwidth and proposes short-term contracts where extra-bandwidth is allocated and guaranteed exclusively to users who can exploit it to transmit at a rate higher than their subscribed rate.
To implement this service model we propose a dynamic provisioning architecture for intra-domain Quality of Service networks. We develop a set of dynamic on-line bandwidth allocation algorithms that take explicitly into account traffic statistics and users’ utility functions to increase users’ benefit and network revenue.
Further, we propose a mathematical formulation of the extra-bandwidth allocation problem that maximizes network revenue. The solution of this model allows to obtain an upper bound on the performance achievable by any on-line bandwidth allocation algorithm.
We demonstrate through simulation in realistic network scenarios that the proposed dynamic allocation algorithms are superior to static provisioning in providing resource allocation both in terms of total accepted load and network revenue, and they approach, in several network scenarios, the ideal performance provided by the mathematical model

MCM-GINS and MCM-MCM interactions in vivo visualised by bimolecular fluorescence complementation in fission yeast
No full textBackground: Each of the three individual components of the CMG complex (Cdc45, MCM and GINS) is essential for chromosomal DNA replication in eukaryotic cells, both for the initiation of replication at origins and also for normal replication fork progression. The MCM complex is a DNA helicase that most likely functions as the catalytic core of the replicative helicase, unwinding the parental duplex DNA ahead of the moving replication fork, whereas Cdc45 and the GINS complex are believed to act as accessory factors for MCM. Results:To investigate interactions between components of the CMG complex, we have used bimolecular fluorescence complementation (BiFC) in the fission yeast Schizosaccharomyces pombe for the first time, to analyse protein-protein interactions between GINS and MCM subunits expressed from their native chromosomal loci. We demonstrate interactions between GINS andMCM in the nuclei of exponentially-growing fission yeast cells and on chromatin in binucleate S-phase cells. In addition we present evidence of MCM-MCM interactions in diploid fission yeast cells. As with GINS-MCM interactions, MCM-MCM interactions also occur on chromatin in S-phase cells. Conclusion: Bimolecular fluorescence complementation can be used in fission yeast to visualise interactions between two of the three components of the CMG complex, offering the prospect that this technique could in the future be used to allow studies on replication protein dynamics in living S. pombe cells.Peer reviewe
The tautological ring of Mg,n via Pandharipande-Pixton-Zvonkine r-spin relations
No full textWe use relations in the tautological ring of the moduli spaces Mg,n derived by Pandharipande, Pixton, and Zvonkine from the Givental formula for the r-spin Witten class in order to obtain some restrictions on the dimensions of the tautological rings of the open moduli spacesMg,n. In particular, we give a new proof for the result of Looijenga (for n = 1) and Buryak et al. (for n > 2) that dimRg-1(Mg,n) ≤ n. We also give a new proof of the result of Looijenga (for n = 1) and Ionel (for arbitrary n > 1) that Ri(Mg,n) = 0 for i > g and give some estimates for the dimension of Ri(Mg,n) for i ≤ g - 2

KOMPETENSI SUMBER DAYA MANUSIA TERHADAP PENCEGAHAN
FRAUD (STUDI EMPIRIS PADA DESA KECAMATAN TALUN
KABUPATEN CIREBON)”
Berbagai permasalahan yang terjadi pada desa karena adanya tindak
kecurangan yang dilakukan oleh aparatur desa, salah satunya adanya kasus korupsi.
Hal ini tentu saja berakibat buruk terhadap desa dan masyarakat. karena pencegahan
Fraud sangat penting diterapkan manajemen desa. Penelitian ini bertujuan untuk
mengetahui pengaruh penyajian laporan keuangan desa, pengendalian internal dan
kompetensi sumber daya manusia terhadap pencegahan Fraud baik secara parsial
maupun simultan.
Penelitian ini menggunakan metode kuantitatif serta teknik pengumpulan
data melalui survei yang dilakukan dengan cara mengumpulkan sampel dengan
menggunakan angket atau kuesioner sebagai alat ukur data. sampel dalam
penelitian ini adalah aparatur desa yang terdapat pada 5 desa di kecamatan talun
Cirebon. Sampel yang digunakan dalam penelitian ini sebanyak 30 aparatur desa
dari masing-masing 5 desa tersebut. penelitian ini menggunakan metode purposive
sampling. Teknik analisis data yang digunakan pada penelitian ini adalah analisis
persamaan regresi linier berganda, koefisien determinasi, uji t, uji F, dengan
bantuan pengolahan data menggunakan aplikasi Statistical Product and Service
Soution (SPSS) Versi 26.
Hasil penelitian ini menunjukkan bahwa: (1) Dalam penelitian ini
menunjukan bahwa penyajian laporan keuangan Desa tidak berpengaruh secara
parsial sebesar 1,061% terhadap Pencegahan Fraud pada Desa di Kecamatan Talun.
(2) Dalam penelitian ini menunjukan bahwa pengendalian internal berpengaruh
secara parsial sebesar 8,680% terhadap Pencegahan Fraud pada Desa di Kecamatan
Talun. (3) kompetensi sumber daya manusia tidak berpengaruh secara parsial
sebesar -0,610% terhadap Pencegahan Fraud pada Desa di Kecamatan Talun, (4)
Penyajian Laporan Keuangan Desa, Pengendalian Internal dan Kompetensi Sumber
Daya Manusia secara Simultan berpengaruh terhadap variabel pencegahan Fraud
pada Desa di Kecamatan Talun sebesar 81,9%.
