We also discuss relevant issues and potentialsolutions to this problem.
Quality of Black Teas in Indian market

Tea (Camellia sinensis) is the second most popular consumed drink in the world after water. Tea has numerous medicinal benefits mainly due to its antibacterial and antioxidant properties. In this study, the levels of Theaflavin (TF), Thearubigin (TR), high polymerized substances (HPS) and total polyphenols (TPP) of different tea brands found in Indian market were determined using UV/Vis spectrophotometric methods. Four brands of black teas were selected [Tata tea (CTC), Red label tea (CTC), Lipton Darjeeling tea (orthodox, Meri Chai and (CTC tea bag)]. Among the different market teas Lipton Darjeeling (orthodox) tea was found to have greater amount of 19.57% polyphenols and Darjeeling tea was found to have the highest aroma index of 15.9.
Disfluencies as intra-utterance dialogue moves

Although disfluent speech is pervasive in spoken conversation, disfluencies have received little attention within formal theories of grammar. The majority of work on disfluent language has come from psycholinguistic models of speech production and comprehension and from structural approaches designed to improve performance in speech applications. In this paper, we argue for the inclusion of this phenomenon in the scope of formal grammar, and present a detailed formal account which: (a) unifies disfluencies (self-repair) with Clarification Requests, without conflating them, (b) offers a precise explication of the roles of all key components of a disfluency, including editing phrases and filled pauses, and (c) accounts for the possibility of self addressed questions in a disfluency. http://dx.doi. org/10.3765/sp.7. 9 BibTeX info
UNificatins and Extensions of the Multiple Access Communications Problem

Abstract : Multiple access protocols permit a broadcast communications channel to be shared by a large number of stations under distributed control. It is assumed that only one message at a time can be transmitted successfully over the common channel. The author derives a local optimality condition for synchronous multiple access protocols, and show that many known protocols are special cases of this condition. Included a survey of much of the recent work on infinite population tree algorithms that use the history of channel activity to carry out short-range dynamic scheduling. A novel approach is presented for deriving upper bounds on the maximum stable throughput with finite average delay for infinite population protocols. Bounds are found for the case of arbitrarily complex algorithms, and for the restricted (but reasonable) class of protocols that obey a degenerate intersection property. This latter class is quite interesting, being a slight generalization of first-come first-served that includes all currently proposed protocols. The model is extended to include multiple access protocols aided by a partial reservation channel. Particular emphasis is placed on multiple access in the context of local networks.
Use of high-frequency seismic waves for the detection of buried landmines

Over the past three years a system has been under development at Georgia Tech that utilizes a seismic interrogation signal in combination with a non-surface- contacting, radar-based displacement sensor for the detection of buried landmines. Initial work on this system investigated the workability of the system concept. Pragmatic issues regarding the refinement of the current experimental laboratory system into a system which is suitable for field testing and, in turn, one which would be suited to field operations have been largely ignored until recently. Both field operations and realistic field testing require a system that is different from the original laboratory system in two crucial ways. One of these is that a field system needs a sensor standoff from the ground surface larger than the original 1 to 2 cm. This is necessary in order to account for small-scale topography, to avoid ground cover such as grass, and to minimize the risk to the operator. A second difference is that the scanning speed of a field system must be substantially greater than that of the original laboratory system, which takes several hours to image 1 m2 of ground surface. From an operational standpoint, the reason for this is obvious. From an experimental standpoint, it is also important because ambient conditions are difficult to control on long time scales outdoors. Both of these new requirements must be met within the design parameters that were established empirically during the development of the laboratory system.
The Experiential Design Move: an approach to reflective practice for embodied and movement based interaction

Recent examples in the design of embodied and movement based interfaces have benefited from the use of reflection in action cycles that have their genesis within established forms of design practice such as Architecture and Industrial Design. What both of these established disciplines share are the use of sketches and models that form artefacts supporting arguments for a particular approach to the design problem. These are established and understood means for reflection and iteration. Designers of embodied and movement based interfaces have begun to apply this reflection in action approach, however the static representations used in Architecture and Industrial design are not sufficient to account for the temporal and experiential concerns of Interaction design and Human Computer Interaction. So the challenge, and the position of this paper, is to open a discussion on what means and tools enable a reflection on the experiential and technological challenges within Interaction Design. This paper gives an account of a recently commissioned interface prototype, the Musical Staircase, which has moved through its first design cycle of Problem Framing, Design Response and User Evaluation to encourage this discussion.
Programmable current mode circuits

The paper presents a new concept of switched transconductor (ST) circuits based on the application of operational amplifiers with adjustable transconductance. It is proved that in the delay circuits proposed, one can electronically adjust its amplification, which was not possible with SI 1st and 2nd generation circuits. For the purpose of verification of the concept, a simple adjustable transconductance amplifier was designed. Simulations of delay circuits were carried out to prove the legitimacy of the concept.
An alternative explanation of the constant stress rupture experiments at the Lawrence Livermore National Lab

The reliability function of a component cannot be satisfactorily estimated from experiments, because: (i) an accurate estimation of the lifetime distribution tails, controlling the most important domain of high reliability, requires a very large sample; and (ii) reliability tests under normal operational conditions are necessarily very lengthy. Hence the urgent need for a physical model for component lifetime statistics. The paper presents an application of the developed model for damage accumulation in polymeric materials to the long-term constant stress rupture experiments on Kevlar composite. The proposed model, based on a single micromechanical damage mechanism, leads to a 2-parameter Weibull lifetime distribution with the shape parameter depending on the applied load by a simple inverse power law. Both distribution models were fitted to experimental lifetime data for different stress levels and the corresponding goodness of fit was compared by the usual likelihood ratio test. The proposed model describes the experimental data better especially in the most important domain of low stress and long (of the order of years) lifetime. The model is physically sound and permits improved design of the accelerated tests and more accurate interpretation of their results, and finally quantitative prediction of the reliability function of the loaded polymeric component.
A multi-dimensional approach to the study of online annotation

In this study we are investigating the relative value (combining frequency of use and user rating) of online annotation according to combinations of form (behaviour) and function (cognitive state) in relation to the prospective audience for the annotations (i.e. private, work group, and larger public). We are also investigating the patterns of behavior and cognitive states of readers while annotating. Using a prototype annotation and linking module developed for the Open Journal Systems, we are carrying out a field study to collect data on patterns of highlighting, annotating, linking and link-typing behavior. In the study participants are asked to read a number of articles provided in OJS, and perform three general tasks: general reading/browsing, directed reading, and confirmatory reading. Data collection on each of these tasks consists of screen capture of the annotation and linking process, retrospective protocols with interviews to elicit reader comments on their own behavior, and pre-/post- questionnaires. Among other findings, it is anticipated that the results of the analysis will provide useful information concerning the frequency with which annotation functions are matched to form, and to the number and kinds of link types that are consistently employed.Furthermore, Dillons (1999) TIME framework is being used in conjunction with our understanding of annotation and linking to assess the prototype system and to understand what makes the annotation tools usable, the likely problems and usability issues in their design, and how various ways of presenting the information changes the users experience.

The design of a device based on this work is then described. The multiplexer uses a gated readout structure and an addressable buffer scheme to integrate the photo-currents generated by a staring array of indium antimonide (InSb) IR photodiodes bump bonded directly to the multiplexer. Fabricated in a 3- mu m CMOS technology, the device has been successfully bonded to a photodiode array, and evaluation results have been obtained at a temperature of 5 K. <<ETX>>
XI Brazilian Symposium on Information Systems ( SBSI 2015 ) Brazilian Symposium on Information Systems ( SBIS ) 5-2015 Maturing , Consolidation and Performance of NoSQL Databases-Comparative Study

This paper presents a study on the NoSQL (Not Only SQL), a new dimension in databases. Lately witnesses an expansion in the number of generated data, and the relational model cannot deal with this data growth. The NoSQL comes as a solution to this problem. This paper aims to conduct a study on the architecture of DBMS, demonstrate why they can deal with this large volume of data and show some properties that NoSQL is based to make your data management. Therefore, DBMSs Redis and Cassandra were used and compared to the relational database MySQL. The maturity and consolidation of NoSQL DBMSs were qualitatively assessed on the parameters online documentation, software help, support virtual community and academic articles, so this work presents a perception of a user already familiar with relational approach taking their first steps with NoSQL. The results showed recognition of the relational database, but also showed a strong consolidation of NoSQL technology market and academic research environments, especially with Cassandra. The horizontal scale was tested with the DBMS Cassandra, who proved to be an excellent tool in this regard.
Urdu in anglicized world: A corpus based study

This paper aims to find out the variation in Urdu language due to language contact. It studies the use of English vocabulary in Urdu written language. The nature of the research is quantitative as well as qualitative as it examines the grammatical and domain-wise categories of English words used in Urdu and tries to determine the social factors that are the cause of this increase. It counts and calculates the frequency and the percentages of English words to examine the diachronic changes in the language. The researchers have taken the corpus of 30,000 words in total which includes15000 words of Urdu magazine published from 1995 to 1997 and the similar corpus of year 2011. The corpus is minutely observed by the researchers and English words are extracted and tested from English to Urdu dictionaries in order to see whether or not English vocabulary is increasing due to (non)availability of their Urdu substitutes. The results reveal that Urdu language is now absorbing English words more than a decade ago. The results also brought forth an interesting fact that the magazines that are promoters of Urdu language are conscious to restrain the use of English. However, English words frequently used by Urdu users are showing up in the written language and are used at the expense of their Urdu correlates. Key words: Code-mixing, code-switching, variation in Urdu.

A turbo/MAP decoder for use in satellite circuits

The implementation and performance of a turbo/MAP decoder is described. A serial block MAP decoder operating in the logarithm domain is used to obtain a very high performance turbo decoder. Programmable gate arrays and EPROMs allow the decoder to be programmed for almost any code from 4 to 512 states, rate 1/3 to rate 1/7 (higher rates are achieved with puncturing), and interleaver block sizes to 65,536 bits. Seven decoding stages were implemented in parallel. For rate 1/3 and 1/7 16 state codes with an interleaver size of 65,536 bits and operating at up to 356 kbit/s the codec achieved an E/sub b//N/sub 0/ of 0.32 and -0.30 dB, respectively for a BER of 10/sup -5/. BERs down to 10/sup -7/ were also achieved for a small increase in E/sub b//N/sub 0/.
Efficient techniques to provide scalability for token-based cache coherence protocols.

Cache coherence protocols based on tokens can provide low latency without relying on non-scalable interconnects thanks to the use of efficient requests that are unordered, However, when these unordered requests contend for the same memory block, they may cause protocols races. To resolve the races and ensure the completion of all the cache misses, token protocols use a starvation prevention mechanism that is inefficient and non-scalable in terms of required storage structures and generated traffic. Besides, token protocols use non-silent invalidations which increase the latency of write misses proportionally to the system size. All these problems make token protocols non-scalable. To overcome the main problems of token protocols and increase their scalability, we propose a new starvation prevention mechanism named Priority Requests. This mechanism resolves contention by an efficient, elegant, and flexible method based on ordered requests. Furthermore, thanks to Priority Requests, efficient techniques can be applied to limit the storage requirements of the starvation prevention mechanism, to reduce the total traffic generated for managing protocol races, and to reduce the latency of write misses. Thus, the main problems of token protocols can be solved, which, in turn, contributes to wide their efficiency and scalability.

Understanding Human Motion Skill with Peak Timing Synergy

The careful observation of motion phenomena is important in understanding the skillful human motion. However, this is a difficult task due to the complexities in timing when dealing with the skilful control of anatomical structures. To investigate the dexterity of human motion, we decided to concentrate on timing with respect to motion, and we have proposed a method to extract the peak timing synergy from multivariate motion data. The peak timing synergy is defined as a frequent ordered graph with time stamps, which has nodes consisting of turning points in motion waveforms. A proposed algorithm, PRESTO automatically extracts the peak timing synergy. PRESTO comprises the following 3 processes: (1) detecting peak sequences with polygonal approximation; (2) generating peak-event sequences; and (3) finding frequent peak-event sequences using a sequential pattern mining method, generalized sequential patterns (GSP). Here, we measured right arm motion during the task of cello bowing and prepared a data set of the right shoulder and arm motion. We successfully extracted the peak timing synergy on cello bowing data set using the PRESTO algorithm, which consisted of common skills among cellists and personal skill differences. To evaluate the sequential pattern mining algorithm GSP in PRESTO, we compared the peak timing synergy by using GSP algorithm and the one by using filtering by reciprocal voting (FRV) algorithm as a non time-series method. We found that the support is 95 100 % in GSP, while 83 96 % in FRV and that the results by GSP are better than the one by FRV in the reproducibility of human motion. Therefore we show that sequential pattern mining approach is more effective to extract the peak timing synergy than non-time series analysis approach.

COORDINACION DE INVENTARIOS EN UNA CADENA DE SUMINISTRO DEL SECTOR AUTOMOTRIZ A TRAVES DE EPOCAS COMUNES DE RESURTIDO, Y EL USO DE DIVERSOS MODOS DE TRANSPORTE

La eficiente gestion de la cadena de suministro requiere la integracion de varias actividades logisticas. En particular los beneficios como la reduccion de costos y mejora del nivel de servicio pueden obtenerse mediante la coordinacion de inventarios y del sistema de transporte. En este sentido, el objetivo de este trabajo se oriento al desarrollo de tres modelos de optimizacion bi-criterio (costos y eficiencia) considerando a la vez la seleccion del modo de transporte y la definicion de una politica de inventario. Un modelo se estructuro en el contexto no coordinado y los otros dos se basaron en la estrategia de coordinacion "Epocas Comunes de Reposicion"; cada modelo supone un unico proveedor que abastece diferentes productos, a traves de tres modos de transporte a un solo cliente con demanda determinista y variable. Para ilustrar la aplicabilidad de los modelos, se considero un caso especifico en el sector automotriz. Resolvimos los modelos, combinado dos metodos interactivos multiobjetivo. Entre las principales conclusiones encontramos que la coordinacion de inventarios beneficia tanto al cliente como al proveedor, pero en algunos casos, no conseguimos resultados positivos, pensamos que se debe al tipo de producto. Por esta razon, creemos conveniente realizar un estudio teniendo en cuenta esta situacion. Se incluyen figuras, cuadros y conclusiones. Abstract:Efficient supply chain management requires integration of several logistical activities. In particular, benefits as costs reduction and service level improvement can be obtained by coordinating inventory and transportation system. In this sense, the objective of this work was oriented to develop three bi-criteria optimization models (cost and efficiency) simultaneously consider the selection of transportation mode and definition of inventory policy. A model was structure in the context non coordinate and others models were based on the coordination strategy "Common Replenishment Epochs"; each model assumes a single supplier of different products, three modes of transport and a single client with deterministic and variable demand. To illustrate the applicability of the models, a specific case study is considered in the automotive sector. We solve models, by mean of the combination two interactive methods multi-objective. Between the principals conclusions we found that in the inventory coordination, are benefits both customer as supplier, but in some case, we don't get positive results; we thought that it is due to type product. For this reason, we think convenient carry out a study considering this situation. Included figures, tables and conclusions.
