An integrated ranking algorithm for efficient information computing in social networks

Social networks have ensured the expanding disproportion between the face of WWW stored traditionally in search engine repositories and the actual ever changing face of Web. Exponential growth of web users and the ease with which they can upload contents on web highlights the need of content controls on material published on the web. As definition of search is changing, socially-enhanced interactive search methodologies are the need of the hour. Ranking is pivotal for efficient web search as the search performance mainly depends upon the ranking results. In this paper new integrated ranking model based on fused rank of web object based on popularity factor earned over only valid interlinks from multiple social forums is proposed. This model identifies relationships between web objects in separate social networks based on the object inheritance graph. Experimental study indicates the effectiveness of proposed Fusion based ranking algorithm in terms of better search results.Comment: 14 pages, International Journal on Web Service Computing (IJWSC), Vol.3, No.1, March 201

Techno-Economic Analysis of Hybrid Layered Manufacturing

Subtractive manufacturing (CNC machining) has high quality of geometric and material properties but is slow, costly and infeasible in some cases; additive manufacturing (RP) is just the opposite. Total automation and hence speed is achieved in RP by compromising on quality. Hybrid Layered Manufacturing (HLM) developed at IIT Bombay combines the best features of both these approaches. It uses arc welding for building near-net shapes which are finish machined to final dimensions. High speed of HLM surpasses all other processes for tool making by eliminating NC programming and rough machining. The techno-economic viability of HLM process has been proved through a real life case study. Time and cost of tool making using HLM promises to be substantially lower than that of CNC machining and other RP methods. Interestingly, the material cost in HLM was also found to be lower. HLM is a cheaper retrofitment to any 3 or 5 axis CNC milling machine or machining center.Mechanical Engineerin

Angular separations of the lensed QSO images

We have analyzed the observed image separations of the gravitationally lensed images of QSOs for a possible correlation with the source redshift. Contrary to the previously noted anti-correlation based on a smaller data set, no correlation is found for the currently available data. We have calculated the average image separations of the lensed QSOs as a function of source redshifts, for isothermal spheres with cores in a flat universe, taking into account the amplification bias caused by lensing. The shape of the distribution of average image separation as a function of redshift is very robust and is insensitive to most model parameters. Observations are found to be roughly consistent with the theoretical results for models which assume the lens distribution to be (i) Schechter luminosity function which, however, can not produce images with large separation and (ii) the mass condensations in a cold dark matter universe, as given by the Press-Schechter theory if an upper limit of 1-7$\times 10^{13}$ M$\odot$ is assumed on the mass of the condensations.Comment: 20 pages, 7 postscript figures, accepted for publication in The Astrophysical Journa

Time Series Analysis of Real Effective Exchange Rate

This paper analyses the trendand seasonal variation of real effective exchange rate (REER) with an objectiveof building a model for predicting the  exchangerate. Classical decomposition  of the timeseries data of monthly  export and trade basedREER from January 2011 to August 2015 has been performed. The trend and seasonalcomponents have been studied. The results show that the trend and seasonal effectare  attributed only to chance (random) andnot by a systematic factor like a trend or a seasonal change.Keywords: Exchangerate, Trend Analysis, Seasonal variation, Classical Decomposition

Testability Assessment Model for Object Oriented Software based on Internal and External Quality Factors

Software testability is coming out to be most frequent talked about subject then the underrated and unpopular quality factor it used to be in past few years. The correct and timely assessment of testability can lead to improvisation of software testing process. Though many researchers and quality controllers have proved its importance, but still the research has not gained much momentum in emphasizing the need of making testability analysis necessary during all software development phases. In this paper we review and analyse the factors affecting testability estimation of object oriented software systems during design and analysis phase of development life cycle. These factors are then linked together in the form of new assessment model for object oriented software testability. The proposed model will be evaluated using analytical hierarchical process (AHP)

Intelligent Retrieval Model: Object Oriented Search Methodology on Web

Information handling through improved search mechanisms is and will remain the driving force behind rich patterns of access to web contents. Keyword search offers only an imperfect solution to information discovery over web as it misses many relevant documents of today2019;s users. By its fundamental nature, keyword search is sharply focused to find the exact terms specified in the query. The proposed Intelligent Retrieval Model exploits the object oriented concepts for information representation. This kind of conceptual modeling of web based inheritance boosts data structuring flexibility and caters to the density of diverse web information needs. The guiding principle of proposed model for intelligent retrieval over World Wide Web is the adequate representation of relevant complex relationships between the various entities in the real world. The result approves better hierarchical relationship recognition among web objects leading to less complex computing

Cervical leiomyomas: a surgeon’s challenge

Leiomyoma are benign uterine tumors of unknown etiology. Only 5% of the cases are cervical and are usually single. Extraperitoneal leiomyomas leads to pressure symptoms. They may be submucosal, intramural or sub-serosal type. Anterior cervical fibroids are the most common. Central cervical fibroids are described as “The Lantern on the dome of St. Paul’s”. A retrospective clinical study of 6 cervical fibroids operated in the department of Obstetrics and Gynecology, in a tertiary care hospital in Mumbai for a period of 24 months from March 2021 to February 2022. Patients were studied with respect to clinical profiles, pre-operative investigations, intra- operative surgical challenges and post-operative surveillance. In our study we observed that cervical fibroids were most commonly diagnosed in the age group of 40-50 years, and most commonly in women of second parity. The most common presenting symptom was pain in abdomen. All patients underwent hysterectomy (abdominal or vaginal), wherein 16% of them required blood transfusion. The largest cervical fibroid operated was 20 x 12 x 10 cm in size with uterus corresponding to 22 weeks of gestation. Excision of cervical fibroids is a challenging procedure due to its close proximity to ureters. It is only with experience and with fine surgical skills that a good patient outcome can be achieved. Even after advent of various alternative management options, surgery remains the mainstay of treatment and is still a surgeon’s nightmare

Surface markers of lymphoblasts in acute lymphoblastic leukaemia

58 children with acute lymphoblastic leukaemia (ALL) were studied for the effect of initial clinical and laboratory features and surface markers of lymphoblasts on the prognosis. 18.9% of them had T cell leukaemia while 3.4% had B-cell leukaemia. Six pre-treatment features were related to T-cell ALL, i.e. - age over 6 years, boys, presence of mediastinal enlargement, haemoglobin over 8g/dl, markedly elevated leucocyte count and CNS involvement. 90% of T-Cell ALL survived for less than 6 months. Both the cases of B-cell leukaemia died within 8 weeks. Identification of T and B cell leukaemia warrants more aggressive treatment for these patients to achieve remission and survive longer
