A Review-: Benefits and Critical Factors of Customer Relationship Management

Customer Relationship Management (CRM) is a technical jargon which is a blend of methodologies, software and internet, which are used by a company to achieve its goal through the identification and satisfaction of customer2019;s stated and unstated needs and wants. This software addresses customer life cycle management. This system manages company interactions with current and future customers. It involves technology to organize, automate and synchronize business processes. CRM application is an essential tool for a company to grow and help to increase the satisfaction of customers. There are many benefits of CRM; those make the market environment customer centric. In this paper, we reviewed previous studies and identify those benefits which affect customers and company both. But CRM has many problems also because of them CRM gets failure. Its failure rate is more than its success rate. We also elaborated its failure factors and along with them its critical success factors which help in making CRM a successful project for a company, however implementation of CRM is a complex task

Surface Characterization and Machining of Blind Pockets on Ti6Al4V by Abrasive Water Jet Machining

AbstractPresent work discusses the method of machining and characterization of blind pockets on Ti-6Al-4V alloy fabricated using Abrasive water jet machining (AWJM) by varying the process parameters; pressure, stand-off distance (SOD) and abrasive size. Depth of pockets was measured by coordinate measuring machine (CMM). Deeper pocket were formed at higher pressure; craters and high waviness were observed on machined surface. Surface waviness (SW) and craters sphericity were observed at many places of machined pocket through 3-D optical profilometer with objective lens (5x) and field of view (FOV 2x) along with the SPIP software. SW was found high at corners (side wall) of the pockets. Digital microscope of 230x and a scanning electron microscope (SEM) were used to observe and analyze the micro structure of the machined pockets

Collective modes and superfluidity of a two-dimensional ultracold Bose gas

The collective modes of a quantum liquid shape and impact its properties profoundly, including its emergent phenomena such as superfluidity. Here we present how a two-dimensional Bose gas responds to a moving lattice potential. In particular we discuss how the induced heating rate depends on the interaction strength and the temperature. This study is motivated by the recent measurements of Sobirey {\it et al.} arXiv:2005.07607 (2020), for which we provide a quantitative understanding. Going beyond the existing measurements, we demonstrate that this probing method allows to identify first and second sound in quantum liquids. We show that the two sound modes undergo hybridization as a function of interaction strength, which we propose to detect experimentally. This gives a novel insight into the two regimes of Bose gases, defined via the hierarchy of sounds modes.Comment: Main text: 7 pages + 6 figures and Supplementary text: 5 pages + 4 figure

Awareness and practices of correct and consistent use of condoms among sexually active males in India - a cross sectional study

Background: About 2.5 million Indian are estimated to be HIV positive apart from the other STIs and around 1/4th of the births are unwanted. Condom has become a popular method being promoted for meeting these challenges. The objectives of the study were to understand the awareness and practices regarding correct and consistent use of condoms among sexually active males in India.Methods: Three randomly selected primary health centers in southern India. All male members reported to be using condoms by the PHCs, were visited at their homes. A pre-tested check list (Yes/No) type questionnaire was used to collect the data. Commonly available guide line regarding correct and consistent were used as the baseline knowledge. Responses thus received were evaluated and graded using five point scales. Income, education and years of use wise differentials were also analyzed.Results: Out of 7326 eligible couples 7.2% were reported to be using condoms. Response rate was 88 percent. 27 (12%), 82 (36%), 89 (39%), 18 (8%) and 11 (5%), were having poor, fair, good, very good and excellent level of awareness respectively and fewer were putting their knowledge into practice. Respondent having schooling for more than ten years or per capita income of more than Rupee 1000 or using condoms since more than five years were having better level of awareness as well as practices.Conclusions: Awareness and practices regarding correct and consistent condom use lags substantially behind the desired levels

The Entropy Influence Conjecture Revisited

In this paper, we prove that most of the boolean functions, $f : \{-1,1\}^n \rightarrow \{-1,1\}$ satisfy the Fourier Entropy Influence (FEI) Conjecture due to Friedgut and Kalai (Proc. AMS'96). The conjecture says that the Entropy of a boolean function is at most a constant times the Influence of the function. The conjecture has been proven for families of functions of smaller sizes. O'donnell, Wright and Zhou (ICALP'11) verified the conjecture for the family of symmetric functions, whose size is $2^{n+1}$. They are in fact able to prove the conjecture for the family of $d$-part symmetric functions for constant $d$, the size of whose is $2^{O(n^d)}$. Also it is known that the conjecture is true for a large fraction of polynomial sized DNFs (COLT'10). Using elementary methods we prove that a random function with high probability satisfies the conjecture with the constant as $(2 + \delta)$, for any constant $\delta > 0$.Comment: We thank Kunal Dutta and Justin Salez for pointing out that our result can be extended to a high probability statemen
