Penerapan Sistem Terdistribusi Pada Together in a Single Connection (Tsc) Berbasis Web

Distributed system is a computer networking technology which can be hardware or software. In hardware distributed system by a collection of computers that are heterogeneous, being in the software system is distributed in the form of software that connects two applications in the form of client and server side. TSC method is a method that already existed before, which can be used increase the ranking o f a blog. Implementation distributed system for TSC using landing page as the intermediary. Landing page serves as a liaison between web applications or blogs are listed as a member to raise the ranking of a database on the application server side. When someone does click on landing page seoindonesia, will open a blog or other web members. Landing page so it can be used as a way to count the number of visitors to a blog or website, which in turn can increase the number o f page visits and 1 with 1 clickbutton seoindonesia for test in histats.com

Webometric analysis of departments of librarianship and information science: a follow-up study

This paper reports an analysis of the websites of UK departments of library and information science. Inlink counts of these websites revealed no statistically significant correlation with the quality of the research carried out by these departments, as quantified using departmental grades in the 2001 Research Assessment Exercise and citations in Google Scholar to publications submitted for that Exercise. Reasons for this lack of correlation include: difficulties in disambiguating departmental websites from larger institutional structures; the relatively small amount of research-related material in departmental websites; and limitations in the ways that current Web search engines process linkages to URLs. It is concluded that departmental-level webometric analyses do not at present provide an appropriate technique for evaluating academic research quality, and, more generally, that standards are needed for the formatting of URLs if inlinks are to become firmly established as a tool for website analysis

A Systematic Study on the Utilization of Inorganic Salts as Catalyst for the Conversion of Xylose to Furfural

The utilization of biomass-waste such as sugar-bagasse,water-hyacynth and palm-oil-fiber as alternative sources for transportation fuels and platform-chemicals is a very active research field. Furfural(FF) is one-of-the-13top platform-chemicals that may be converted to derivatives such as furfuryl-alcohol,furoic-acid and furan with wide applications in the gasoline,diesel and jet-fuel blending-pool. Many studies have been conducted in the mechanism and the kinetics of FF-formation from xylose since the 1940s to maximize FF-yield and to reduce FF-decomposition to undesired-products. Previous studies showed that inorganic-salt gives positive effects on the FF-yield but systematic studies are lacking. Based on it, 60salts were screened in the hydrolysis of 0.1M xylose-aqueous-solution (T=180°C,90minutes,batch). The maximum FF-yield was 53mol% using 5mM-Fe2(SO4)3. The highest FF-selectivity was at 84mol% using 5mM-NaCl, though at low xylose-conversion(35 mol%-FF-yield). Some transition metal-chloride i.e.FeCl2,CuCl2,SnCl2 showed interesting FF-yields(48-50%) and selectivity(58-65%) indicating interesting roles of ion Fe3+ and Cl-. Subsequent studies of two salts i.e.Fe2(SO4)3 and FeCl3(5mM) in combination with HCl and H2SO4(0.1M) were investigated(0.1M-xylose,T=150°C,0-270 min). The result shows that salts increase no FF-yields for H2SO4 but increase the reaction-rate. In contrast, Fe2(SO4)3 increase no yield nor reaction-rate for HCl-catalyzed-system. In conclusion, the inorganic-salts catalyse xylose-conversion to furfural but best results were obtained using HCl without additional salts

Administration o f networking IP addressing especially IP version 4 have a less using IP address for the limited. Through for the using by networking o f services base on TCP/IP addressing, however that can be used VLSM (Variable Length Subnet Masking) method o f subnetting addressing thorough the public area networking to divided IP addressing private it\u27s called as sub network ID or Local Area Network (IP private). Therefore dividing have choose a calculate IP addressing o f VLSM Method used by simulator calculating IP address subnetting. The use o f goal-based subnetting android simulator to facilitate the distribution o f IP within the network administrator by using the simulator VLSM IP subnetting calculations automatically and efficiently. An application that helps administrators in calculating VLSM subnetting IP, to support network administration so that administrators can make solving the network ID into sub-networks. IP results obtained from the simulator, can be tested with VLSM on various internet network service providers obtain a quite optimal for purposes o f network administration

Identifying Solar Flare Precursors Using Time Series of SDO/HMI Images and SHARP Parameters

We present several methods towards construction of precursors, which show great promise towards early predictions, of solar flare events in this paper. A data pre-processing pipeline is built to extract useful data from multiple sources, Geostationary Operational Environmental Satellites (GOES) and Solar Dynamics Observatory (SDO)/Helioseismic and Magnetic Imager (HMI), to prepare inputs for machine learning algorithms. Two classification models are presented: classification of flares from quiet times for active regions and classification of strong versus weak flare events. We adopt deep learning algorithms to capture both the spatial and temporal information from HMI magnetogram data. Effective feature extraction and feature selection with raw magnetogram data using deep learning and statistical algorithms enable us to train classification models to achieve almost as good performance as using active region parameters provided in HMI/Space-Weather HMI-Active Region Patch (SHARP) data files. Case studies show a significant increase in the prediction score around 20 hours before strong solar flare events

Synthesis of Higher Fatty Acid Starch Esters using Vinyl Laurate and Stearate as Reactants

This paper describes the synthesis of long-chain fatty esters of corn starch (starch laurate and starch stearate) with a broad range in degree of substitution (DS = 0.24-2.96). The fatty esters were prepared by reacting the starch with vinyl laurate or vinyl stearate in the presence of basic catalysts (Na(2)HPO(4), K(2)CO(3), and Na acetate) in DMSO at 110 degrees C. The yellowish products were characterized by (1)H-, (13)C-NMR and FTIR. The DS of the products is a function of the carbon number of the fatty acid chain, vinyl ester to starch ratio and the type of catalyst. When performing the reactions using Na(2)HPO(4) as the catalyst, the DS for the starch laurate compounds is higher than for the corresponding starch stearates. For low vinyl ester to starch ratios, an increase in the vinyl ester concentration leads to higher product DS values. At higher ratios, the DS decreases, presumably due to a reduction of the polarity of the reaction medium. K(2)CO(3) and Na acetate are superior catalysts with respect to activity compared to Na(2)HPO(4) and products with DS values close to 3 were obtained
