Lajau Kopi is a cafe located in Batu Aji, Batam, and utilizes the internet with total bandwidth of 20 Mbps. The high access users who use internet, connection becomes unstable, sometimes fast or slow number downloader application results decreased performance network, purpose this research to optimize so that available can be used evenly apply PCQ method. as one management methods used. For rea...

The Grid Datafarm architecture is designed for global petascale data-intensive computing. It provides a global parallel filesystem with online petascale storage, scalable I/O bandwidth, and scalable parallel processing, and it can exploit local I/O in a grid of clusters with tens of thousands of nodes. One of features is that it manages file replicas in filesystem metadata for fault tolerance a...

Universal serial bus (USB) is a popular method for personal computers (PC) to communicate with peripherals via cables. In some applications, it’s desirable to isolate the USB communication to achieve safety requirements, or break ground loops. Unfortunately the isolation task is not trivial because of the bi-directional data flow on the USB cable. This article discusses this and other challenge...

Software Defined Network (SDN) merupakan paradigma baru dalam jaringan komputer yang memisahkan antara dataplane dan control plane. Dengan pemisahan tersebut konfigurasi akan lebih mudah dilakukan tidak serumit pada konvensional. Pada penelitian ini dibahas mengenai bagaimana penerapan metode network slicing menggunakan FlowVisor SDN dengan POX sebagai kontrolernya. memungkinkan tiap slices dap...

Quakingviable (qk(v)) is a well known dysmyelination mutation. Recently, the genetic lesion of qk(v) has been defined as a deletion 5' to the qkI gene, which results in the severe reduction of the qkI-encoded QKI RNA-binding proteins in myelin-producing cells. However, no comprehensive model has been proposed regarding how the lack of QKI leads to dysmyelination. We hypothesized that QKI binds ...

The convergence of Artificial Intelligence (AI) can overcome the complexity network defects and support a sustainable green system. AI has been used in Cognitive Internet Things (CIoT), improving large volume data, minimizing energy consumption, managing traffic, storing data. However, smart packet transmission scheduling (TS) CIoT is dependent on choosing an optimum channel with minimum estima...

We consider a scheduling rule called MBPS, the mean bounded priority scheduling, which prioritizes jobs by an index computed for each job as a weighed sum of the proportion of time it has been processed and the proportion of time it has been waiting for processing. Proof that MBPS is a deteriorating or a delaying jobs single-machine scheduling problems is given. Two expressions of this dynamic ...

Future wireless networks must be able to coordinate services within a diverse network environment. Next generation wireless network is envisioned as a convergence of different wireless access technologies providing the user enhanced connection any where any time to improve the systems resource utilization. In such converged systems, co-existence of heterogeneous access technologies with largely...

Escherichia coli maltose-binding protein (MBP) is frequently used as an affinity tag to facilitate the purification of recombinant proteins. An important additional attribute of MBP is its remarkable ability to enhance the solubility of its fusion partners. MBPs are present in a wide variety of microorganisms including both mesophilic and thermophilic bacteria and archaea. In the present study,...

The next step in the evolution of wireless local area networks (LANs) is an increase in the data rate from the present rates of a few Mbps to tens of Mbps. As a result of the faster rates the normalized delay-spread increases and simple modulation and demodulation has to be augmented by adaptive equalization. This paper investigates the equalizer requirements of a 4-QAM based system operating a...
