Enhancement in Agile Development Methodologies Using Extreme Programming to Overcome Large Scale Firm ’ s Implementation Problem

Extreme programming is one of the most effective and commonly used agile development methodology among software development methodologies. But in extreme programming, quality activities were executed consecutively along with the functional requirements. It reduces the rapidity in continuous iterations and makes inverse relation between quality and agility. Agile development worked with the small scale projects along with few experts team but not for large project. It could not be implemented properly due to scaling and estimation problem. Extreme programming (XP) with enhancing capabilities enabled agile methods to work efficiently for large scale organizations. XP was best suitable to be documentation and easier to implement. System engineering approach was considered as incremental change related to coding. Extreme programming was enabling hundreds of programmers and software engineers to work on large projects using agile development methodologies.

ISOLATION AND IDENTIFICATION OF LACTIC ACID BACTERIA FROM FERMENTED CHICKPEAS

In this study, lactic acid bacteria were isolated from the fermented chickpeas, which is a leavening agent and phenotypically identified. Chickpea seeds was traditionally fermented and sampling was performed at the end of the fermentation (at 40°C for 16h). A total of 60 isolates of lactic acid bacteria were phenotypically identified in chickpea fermentation liquid. Lactococcus lactis was the dominant species (90%) in the samples, followed by L. plantarum (6.7%) and L. brevis (3.3%). According to the results, fermented chickpea is a good source as a leaving agent for chickpea-bread production.
Improving real-time capability of TCP for multimedia streaming using time-controlled window algorithm

TCP is not suitable for real-time application in nature as it provides reliability over timeliness. The incoming data will first be hold in the TCP buffer and sent accordingly until acknowledgement received or timeout occurred, resulting in possibly the transmitted data being obsolete at the receiver. In this paper, a time-controlled window (TCW) algorithm is proposed to improve the real-time capability of TCP. Computer simulations using Network Simulator 2 (NS2) demonstrate the efficacy of the proposed algorithm. Key-Words: TCP, Multimedia Streaming
11 79 9 v 2 [ qu an tph ] 1 J ul 2 01 9 Coherence assisted non-Gaussian measurement device independent quantum key distribution

Non-Gaussian operations on two mode squeezed vacuum states (TMSV) in continuous variable measurement device independent quantum key distribution (CV-MDI-QKD) protocols have been shown to effectively increase the total transmission distances drastically. In this paper we show that photon subtraction on a two mode squeezed coherent (PSTMSC) state can further improve the transmission distances remarkably. To that end we also provide a generalized covariance matrix corresponding to PSTMSC, which has not been attempted before. We show that coherence, defined as the amount of displacement of vacuum state, along with non-Gaussianity can help improve the performance of prevalent CV-MDI-QKD protocols. Furthermore, since we use realistic parameters, our technique is experimentally feasible and can be readily implemented.
Strategic Overbidding for Toehold in Dynamic Auctions : Structutal Estimation of the Synergy Effect

In this paper, we formulate and estimate a dynamic auction game where bidder asymmetry due to synergy is endogenous. The seller sells multiple goods via a sequence of first price auctions. While bidders are ex-ante symmetric, the first period winner has a valuation advantage due to synergy in the second period bidding game and becomes a strong bidder. Being a strong bidder gives advantage in bidding in the second stage. This endogenous synergy creation leads to overbidding in the first period auction relative to a static bidding game. We characterize the equilibrium in terms of the observed bid distribution. We suggest a two step estimation procedure to estimate such a dynamic game of toehold creation. The OCS oil tract auctions exhibit one such phenomenon. We apply our method to data on OCS oil tract auctions. We find that the federal government is only recovering 52% of the ‘strong’buyers’ willingness to pay in the second period. Bidders perceive the value of synergy to be about 5% of their first period’s informational rent. A new semiparametric structural test cannot reject the hypothesis of the strong bidder’s valuation superiority in the second period and sets it at 45% relative to the weak bidder. We use the estimates to design alternate mechanisms and empirically show that government’s revenue could have increased by about 27%.

CD5-FITC / CD19-PE

AND EXPLANATION Flow Cytometry (FC) is a powerful tool for the analytical and quantitative characterization of cells which provides rapid, quantitative and multiparametric analysis of heterogeneous cell populations on a cell-by-cell basis. Flow cytometry is performed on cells in liquid suspension that have been incubated with fluorescently-labeled antibodies directed against specific cellular proteins. The relative fluorescence intensity of the positive cells indicates the amount of antibody bound to specific binding sites on the cells, and therefore provides a relative measure of antigen expression. The CD5-FITC MAb recognizes a 67 kDa antigen expressed by a majority of thymocytes and mature T cells and a subset of B cells . CD5 is expressed at low density on thymocytes and at high density on all mature T lymphocytes. The majority of T cell malignancies expresses CD5, and almost 85% of T cell acute lymphoblastic leukemias are CD5 positive. Further, CD5 is expressed at low density on a small subset of mature B lymphocytes, which is expanded in several autoimmune disorders as well as in some B-cell derived lymphoproliferative disorders such as chronic lymphocytic leukemia (CLL) and centrocytic leukemia . The CD19-PE MAb recognizes the CD19 antigen present in B cells, and can therefore be used in the characterization studies for immunophenotyping of lymphocytes. The CD19 antigen appears early during B cell maturation, it is expressed continuously throughout the remainder of B lymphocyte differentiation including the resting and the activated mature peripheral blood or lymphoid tissue B lymphocyte, and it is lost at the last stage of B lymphocyte differentiation, the plasma cell. The CD19 expression is maintained in Blineage cells that have undergone neoplastic transformation. Antibodies to CD19 are widely applied in the characterization and follow-up of acute and chronic lymphoproliferative disorders (3, 4). The co-expression of CD5 and CD19 antigens enables B-CLL (CD5+CD19+) to be differentiated from T cell lymphoproliferative syndromes (CD5+CD19-).
EFFECT OF THE INCORPORATION OF THE LIVE YEAST ( Saccharomyces cerevisiae ) ( LEVUCELL Sc 10 . ME ) IN THE FEED CONCENTRATE ON GROWTH PERFORMANCE OF LAMBS BLACK

The effect of yeast incorporated Saccharomyces cerevisiae (LEVUCELL Sc 10. ME) at different doses in concentrated feed on growth performance of lambs of the Black Thibar breed was studied. Forty-five (45) lambs were divided into three homogeneous groups for live body weight (17.08 ± 2.49 kg) and for age (147 ± 12 days). Lambs were fed a basic ration of oat hay ad libitum and 400 g /lamb/d of concentrate feed during a 78 days trial period. Lambs in each group received food concentrates differing in the amount of yeast. The control group (C), concentrate feed contains no yeast; the group (DR) with concentrated feed contains 0.4 g of yeast and group (DD) in which the food concentrate contains 0.8 g of yeast. The intake of dry matter of the basal diet was 24.4; 22.4 and 22.0 g DM/kg W 0. 75 for groups C, DR and DD respectively. The average live weight was 25.82; 25.92 and 26.06 kg for groups C, DR and DD respectively. The average weight gain was 148.54; 144.3 and 149.67 g/d groups (C), (DR) and (DD) respectively. The consumption index was 4.16; 3.6 and 3.15 kg DM/kg) groups (C), (DR) and (DD) respectively. In conclusion, the group (DD) has relatively high performances than the group (DR).
The Reliability Test on Psychological Instrument of SESRS , SEPRS and SETRS in Assessing Students ’ Self-Efficacy . Advantages To Students , Parents and Teachers

Self-efficacy is about a person’s belief in his or her ability to perform certain behaviors in order to attain expected outcomes (Weiten, 2010; Bandura, 1995). The purpose of this study was to determine the reliability of the Self-Efficacy Student Report Scales (SESRS), Self-Efficacy Teacher Report Scales (SETRS) and Self-Efficacy Parent Report Scales (SEPRS). This pilot study involved 82 respondents consisting of 38 secondary students aged 13 to 17 years old, 38 parents of the students either father or mother and 6 classroom teachers of the students from SMK Pekan, Telipok, Tuaran. The result showed that overall participants' responses to the items based on the categories provided (students, teachers and parents) were reliable due to the coefficient level were within the acceptable values, which was higher than r = . 50. This study also examined the consistency of four self-efficacy constructs between the two studies. Although some of the subscales in the instruments did not reach higher than r =. 50 however, the consistency of the instruments was still significantly consistent between the 2 periods of time based on test-retest reliability (Pearson) coefficient. Based on the findings, SESRS and SEPRS correlates significantly r = . 50, and also between SEPRS and SETRS, r = . 36. This means that these instruments have internal consistency in measuring the same construct. So it is an advantage if the concept of self-efficacy can be based not only on the subject’s own perception but from others’ point of view especially from the teachers and parents. This can develop a comprehensive understanding of one’s self-efficacy thus helping the children not to overestimate or underestimate their level of self-efficacy. Thus, this will give advantage to students, teachers as well as the parents.
Self-rated Health (SRH) among Elderly Diabetics in an Urban Setting of Assam, India. -

Introduction: Self-rated health (SRH) is considered as the global indicator of health and quality of life. Diabetes is serious chronic disease and it is emerging as a major public health problem among urban population. We aimed to examine the association between SRH and diabetes among elderly population (≥60 yr)) in an urban setting of Assam. Methods: A cross-sectional study was carried out among elderly individuals (≥60 yr) in two randomly selected wards of Dibrugarh urban area of Assam. Pre-tested questionnaire was used to collect data on self-rated health (SRH), sociodemographic and other information. Diabetes was defined as per criterion of American Diabetes Association (ADA). Results: A total of 300 eligible persons (Male-149, Female-151) were recruited into the study. Prevalence of diabetes was found to be 23% (Male-26.2%, Female-19.9%). Higher proportion of diabetic individuals (61%) rated their health as poor as compared to their non-diabetic counterparts (37.7%). Presence of diabetes was found to be significantly associated with poor SRH both in univariate and multivariate logistic regression analysis. Among those with diabetes, sub-groups such as widow/widowers, older individuals, individuals with lower education, and those having higher numbers of morbidities were more likely to report poor SRH. Conclusions: The findings indicate that diabetes is significant contributor of poor SRH among elderly individuals. The study emphasizes the need for developing urgent strategies for preventing/postponing diabetes in the population in order to improve quality of life at old age.
Saddle Point Method in the analysis of pattern statistics for regular languages

In a recent work we have determined the local limit distribution of pattern statistics representing the number of occurrences of a symbol in words of length n in a regular language generated at random according to a suitable stochastic model. Such a model is defined by a finite automaton with weights in R+, consisting of two primitive components, having some transition from the first to the second component. In the present work we extend those results to the case when there is no communication among the components, and hence the associated formal series is the sum of two rational series recognized by finite state automata with primitive transition matrix. We obtain local limit laws of Gaussian type when there is a dominant component or when, in equipotent case, the main terms of mean value and variance are equal. On the contrary, if these terms are not the same then the local limit distribution is a convex combination of Gaussian laws. All convergence rates of our limits are of the order O(n−1/2). This completes the analysis of local limit laws of symbol statistics under a bicomponent stochastic model.
Quality Mapping of O ff set Lithographic Printed Antenna Substrates and Electrodes by Millimeter-Wave Imaging

Offset lithographic printed flexible antenna substrate boards and electrodes have attracted much attention recently due to the boost of flexible electronics. Unmanned quality inspection of these printed substrate boards and electrodes demands high-speed, large-scale and nondestructive methods, which is highly desired for manufacturing industries. The work here demonstrates two kinds of millimeter (mm)-wave imaging technologies for the quality (surface uniformity and functionality parameters) inspection of printed silver substrates and electrodes on paper and thin polyethylene film, respectively. One technology is a mm-wave line scanner system and the other is a terahertz-time domain spectroscopy-based charge-coupled device (CCD) imaging system. The former shows the ability of detecting transmitted mm-wave amplitude signals only; its detection is fast in a second time scale and the system shows great potential for the inspection of large-area printed surface uniformity. The latter technology achieves high spatial resolution images of up to hundreds of micrometers at the cost of increased inspection time, in a time scale of tens of seconds. With the exception of absorption rate information, the latter technology offers additional phase information, which can be used to work out 2D permittivity distribution. Moreover, its uniformity is vital for the antenna performance. Additionally, the results demonstrate that compression rolling treatment significantly improves the uniformity of printed silver surfaces and enhances the substrate’s permittivity values.
Number : WUCSE-2003-15 2003-03-18 Hash Tables for Embedded and Real-time systems

Common collection objects such as hash tables are included in modern runtime libraries because of their widespread use and efficient implementation. While operating systems and programming languages continue to improve their real-time features, common implementations of hash tables and other collection objects are not necessarily suitable for real-time or embedded-systems. In this paper, we present an algorithm for managing hash tables that is suitable for such systems. The algorithm has been implemented and deployed in place of Java’s Hashtable class. We present evidence of the algorithm’s performance, experimental results documenting our algorithm’s suitability for real-time, and lessons learned from migrating this data structure to real-time and embedded platforms.

Recent developments in visuo-vestibular restitution of self-motion in driving simulation

Automotive research applications, from vehicle design to human factors, are of increasing importance in the domain of driving simulation nowadays. One of the reasons is the evolution of visual and kinesthetique rendering techniques and technologies, the other one is the industrial use of driving simulation as a cost effective design tool to be used in the vehicle development process. This latter has arrived to maturation as the rendering techniques allow today to carry out representative experimentations in the studied driving conditions but also because of the extreme strengthening of competition between car makers in cost effectiveness making more realistic the use of virtual prototypes. Virtual driver station design requires the use of head mounted display equipped driving simulators, virtual driving prototypes involve the use of large amplitude high fidelity motion platforms. For both of these systems perceptual and user assessment experimentations will be necessary to be carried out.
Phosphorus Recycling from manure – A Case Study on the Circular Economy : Work package 4

In this case study paper, phosphorus recycling from manure is discussed, with a special focus on the recycling process developed by the BioEcoSIM consortium. We analysed phosphorus flows globally, at a European level and on a national level, with a focus on the Netherlands. In the Netherlands, as in some other regions in Western Europe, there is excess supply of manure due to intensive livestock production. The oversupply, combined with legislation, generates a negative manure price. This negative manure price creates the business case for BioEcoSIM and other manure processing techniques. The BioEcoSIM technique processes manure into phosphorus and nitrogen fertilizer as well as an organic soil improver or biochar. By extracting from manure the useful components, transport costs are reduced. Furthermore, greenhouse gas emissions and particulate matter formation are decreased. However, since manure is already almost completely recycled on arable and pasture land, the effect on phosphorus flows is limited. The EU phosphorus flows show that the main losses of phosphorus in the food sector are through sewage sludge, other waste water and food waste, and not through manure. Nonetheless, losses of phosphate from manure do have a high environmental impact, since it causes eutrophication. This paper shows also what the macroeconomic consequences of phosphorus recycling from manure will be.
1 Quality Spaces and Sensory Modalities

Perhaps nothing in the theoretical study of mind has occasioned more debate than the qualitative character of states such as perceptions, bodily sensations, and emotions. Such qualitative character seems to resist physicalist treatment and, moreover, to cause difficulties beyond those that affect accounts of purely intentional states, such as thoughts and desires. But before one can usefully address the question of whether some phenomenon, mental or otherwise, can be given a naturalist or physicalist account, one must have some suitable way of fixing the phenomenon we want to account for. Many discussions take it for granted that we can do that well enough by way of our introspective or intuitive understanding of qualitative character, and that nothing beyond the deliverances of intuition and introspection is needed. Indeed, many discussions assume that there simply is nothing more to say about what it is for a mental occurrence to exhibit qualitative character or what such qualitative character consists in. We know what it is simply from our being in states that exhibit it; there is no more informative account to be had. Such an approach is unduly dismissive. First-person access is doubtless important to understanding the nature of conscious qualitative character. But we also ascribe states with qualitative character to others, and indeed often feel confident that we know, independent of others’ reports, what qualitative states they are in. So wemust have some understanding of what qualitative character consists in cast in third-person terms. The idea that we know nothing of the nature of qualitative mentality except what first-person access tells us does much to undermine any promise of a naturalist or
On the Kermack-McKendrick Approximation for Removals from an Epidemic

The Kermack–McKendrick model for the SIR epidemic is re-examined with particular attention to the exponential approximation used by them to estimate the final number of removals. It is shown that while this approximation is valid when the initial number x0 of susceptibles is close to ρ, the ratio of the removal to the infection parameters, it fails when x0 > ρ. In all cases the exact number of removals is greater than the approximate number.
How Can Simulations Be Components of Balanced State Science Assessment Systems ?

Analyses indicated that the simulation-based assessments met acceptable standards for reliability and validity. The study also found evidence that because the simulation-based assessments contain more visual representations and less text, they allow English language learners and students with disabilities to better demonstrate their science content knowledge and particularly their science inquiry skills than on more traditional paper-and-pencil tests.
