Quality of service (QoS) is an important performance indicator for Web applications and bandwidth is a key factor affecting QoS. Current methods use network protocols or ports to schedule bandwidth, which require tedious manual configurations or modifications of the underlying network. Some applications use dynamic ports and the traditional port-based bandwidth control methods cannot deal with them. A new QoS control method based on local bandwidth scheduling is proposed, which can schedule bandwidth at application level in a user-transparent way and it does not require tedious manual configurations. Experimental results indicate that the new method can effectively improve the QoS for applications, and it can be easily integrated into current Web applications without the need to modify the underlying network.

Third-generation sequencing using nanopores as biosensors has recently emerged as a strategy capable to overcome next-generation sequencing drawbacks and pitfalls. Assessing the quality of the data produced by nanopore sequencing platforms is essential to decide how useful these may be in making biological discoveries. Here, we briefly contextualized NanoR, a quality control method for nanopore sequencing data we developed, in the scenario of preexistent similar tools. We also illustrated 2 quality control pipelines, readily applicable to nanopore sequencing data, respectively, based on NanoR and PyPore, a second quality control method published by our group.

Customer satisfaction, emotional bonding, trust, choice reduction and habit, too history with company is a key factor for convince the customer to use product and services continue, the other factors can make customers become loyal to the quality of products and promotions. This study aims to measure the performance of services provided by regional companies such as PDAM to the community, the level of customer satisfaction is a reflection of the company's performance, a measurable data is needed that is taken directly to customers. With the help of the Importance Performance Analysis method, performance can be measured and easily understood by decision makers. So that poor performance can be seen and anticipated for future needs. Customer satisfaction of PDAM reaches 74.49% with the main priority that needs to be improved from the services provided are the ability of Social Media Admin Website Officers with performance indicator values of 2.93 and importance indicator values of 3.10. (D.Quadrant Concentrate Here).

There are currently various algorithms with mass spectrometry in phosphorylation identification. Some quality control methods have also been proposed. However, a detailed comparative analysis among various methods has not been reported. In the paper, based on the theory of forward-reverse databases searching, we compare current major algorithms in database searching and identification i.e Mascot and Sequest, and compare various aspects and methods of algorithms in site assessment. We propose an effictive quality control method. Our result shows that this method can ensure the quality of identification and identify more phosphorylation sites.

Analysis of low-sugar preserved Kiwifruit processing status and the key factors of quality control, based on the comparative study of different control methods, fuzzy control technique is applied to the quality control of low-sugar preserved Kiwifruit with using the embedded microcontroller processor to design the system controlling hardware, and the system software flowchart. The control studies of the end product quality of the low-sugar preserved Kiwifruit can provide the technical basis and process control method for low-sugar food-preserved fruit production process , so the corresponding products satisfy the people's low-sugar and low-calorie requirements.

This paper deals with the quality of service in IP Multimedia Subsystem networks. The evaluation of Quality o Service (QoS) is done through admission control methods. We analyse various methods, which are based on the traffic measurement. The approach that can be applied in finding the suitable admission control method while considering selected QoS parameters is described. Different important QoS parameters can be defined, however we decided to focus on the loss parameter. In our simulations we have used Simple Sum method. Based on the simulation results, we have used new algorithm. The main difference is that it uses the mechanism of time window for achieving more accurate traffic estimate. Algorithm Measured Sum with implementation of time window T has better ability to predict the traffic fluctuation. Compared to the Simple Sum algorithm it achieves lower link utilisation, but also lower level of loss ratio.

This study was conducted to determine the growth and flower quality of single-node cutting rose `Versillia' under two different irrigation control methods (time clock and integrated solar radiation). The frequency of irrigation was controlled by time clock and integrated solar radiation of 1.25 and 2.09 and 3.35 MJ·m-2 in aeroponics. Photosynthesis was the highest in the integrated solar radiation of 2.09 MJ·m-2 and 1.25 MJ·m-2 the lowest in the integrated solar radiation of 3.35 MJ·m-2. The growth of single-node cutting rose `Versillia' at 1.25 MJ·m-2 and 2.09 MJ·m-2 was better than 3.35 MJ·m-2 for stem length and fresh weight. Root activities of single-node cutting rose were significantly higher at 2.09 MJ·m-2 and 1.25 MJ·m-2 than those at 3.35 MJ·m-2. The irrigation control method using integrated solar radiation of 1.25-2.09 MJ·m-2 showed a improvement of plant growth and flower quality.

In this paper we present admission control methods for IMS network. The task of RACS block is to accept or reject new connection into the network. The main goal of the admission control method is to ensure the Quality of Service not only for new connection but also for already accepted connections. We discuss and compare three admission control algorithms in the paper from the qualitative parameters point of view.

The premise of the article is the contention that Beckett studies have been focused too much on the philosophical, cultural and psychological dimensions of his established canon, at the expense of the artistry. That research on Beckett's work is issue-driven rather than otherwise, and the slender extant body of criticism specifically on his poetic achievements bears no comparison with the massive exploration of the other facets of Beckett's artistic activity. The critical neglect of Beckett's poetry may not be commensurate with the quality of his verse. And it is in the spirit of remedying this oversight that the present article is offered, focusing on ‘Enueg I’, a representative poem from Echo's Bones, which exhibits all the salient features of Beckett's early poetry. It is argued that Beckett's early verse display the twofold influence, that of the transatlantic Modernism of Eliot and Pound, and of French poetry, specifically the visionary and experimental works of Rimbaud, Apollinaire, and the surrealists. Furthermore, the article also demonstrates that ‘Enueg I’ testifies to Beckett's ambition to compose a complex long Modernist poem in the vein of The Waste Land or The Cantos. Beckett's ‘Enueg I’ has much in common with Eliot's exemplary disjunctive Modernist long poem. Both poems are premised on the acutely felt cultural crisis and display the similar tenor in their ending. Finally, they both close with the vision of the doomed and paralyzed world, and the prevalent sense of sterility and dissolution. In the subsequent analysis, which takes up the bulk of the article, careful attention is paid to the patterning of the verbal material, including also the most fundamental level, that of the arrangements of phonemes, with a view to uncovering the underlying network of sound patterns, which contributes decisively to the semantic dimension of the poem.

The article explores individual approaches used to measure and evaluate the quality of financial state-ments: standardized assessment, accrual-based models (accrual quality), Beneise models (M-Score), in-dexes - the internal control method and the degree of accounting conservatism. The reason for the great dependence on the use of indirect measures (proxies for the quality of financial statements or stock prices) is that some of the qualities of financial statements are unobservable.
