Third-order problems have been found to model real-life phenomena such as thick film fluid flow, boundary layer problems, and nonlinear Genesio problems, to name a few. This research focuses on the development of an algorithm using a basis function that combines an exponential function with a power series. This algorithm, called the Exponential Function Induced Algorithm (EFIA), was formulated using the collocation and interpolation techniques. The theoretical analysis of the algorithm was also carried out in this research. The outcome of the analysis showed that the algorithm is consistent, convergent, and zero-stable. The EFIA was applied to solving some real-life third-order problems like thin film flow and nonlinear Genesio problems. The numerical and graphical results obtained showed that the EFIA is accurate, has high precision, and is easy to implement.

Universities are among the several organizations with complex activities regarding staff records, payroll, and staff promotion.This work intends to use Data warehouse as a solution to simplify these complex activities.Due to their ability to combine heterogeneous data from several information sources in a single storage location for querying and analysis, data warehousing is gaining importance in terms of strategic decision making throughout time.Data collection is a long-standing practice among organizations.Building a massive data warehouse enables them store all important and relevant information.This information is available, but very few organizations have been able to use it to make informed decisions.Due to the significant role played by the Data Warehouse (DW) and Data Mining in strategic decision making, this work developed a Data Warehouse system that can be used academic staff promotion in a University.The prototype which demonstrated the benefits of Data Warehouse and sensitizes universities in Nigeria to start binding such facilities into their staff management system for the purpose of establishing effective administrative system.The system was implemented under oracle Data Warehouse Builder and is meant to serve as a repository of data for data mining operations.The system offers high degree of accuracy in predicting the case of promotion, staff-students ratio as well as the budget projection.

The CMS experiment will change it's silicon tracker completely during phase-II upgrade.There is need to develop light and high precision and durable mechanical structure for silicon modules.The prime purpose of this should also be reducing material in the silicon tracker detector.The group at IIT Madras is involved in R&D of production of this structures.We have produced high precision bridge made of AL-CF material and carbon fiber stiffener.

Measurements of lifetimes in the decay channels $$B^0\rightarrow J/\psi K^*(892)^0$$, $$B^0\rightarrow J/\psi K^0_s$$, $$B^0_s\rightarrow J/\psi \pi ^+\pi ^-$$, $$B^0_s\rightarrow J/\psi \phi $$, $$\varLambda ^0_b\rightarrow J/\psi \varLambda ^0$$ and $$B^+_c\rightarrow J/\psi \pi ^+$$, and polarization of $$\varLambda _b$$ in $$\varLambda _b\rightarrow J/\psi \varLambda $$ decays are presented. The data used are collected by the CMS experiment in proton–proton collisions at centre-of-mass energy $$\sqrt{s}=$$ 7 and 8 TeV corresponding to an integrated luminosity of 5 fb$$^{-1}$$ and 19.7 fb$$^{-1}$$, respectively. The measured lifetimes in $${\upmu }$$m are $$c\tau _{B^0\rightarrow J/\psi K^*(892)^0}= \, 453.0\pm 1.6(\mathrm {stat})\pm 1.8(\mathrm {syst})$$, $$c\tau _{B^0\rightarrow J/\psi K^0_s}=457.8\pm 2.7(\mathrm {stat})\pm 2.8(\mathrm {syst})$$, $$c\tau _{B^0_s\rightarrow J/\psi \phi }=443.9\pm 2.0(\mathrm {stat})\pm 1.5(\mathrm {syst})$$, $$c\tau _{B^0_s\rightarrow J/\psi \pi ^+\pi ^-}=502.7\pm 10.2(\mathrm {stat})\pm 3.4(\mathrm {syst})$$, $$c\tau _{\varLambda ^0_b\rightarrow J/\psi \varLambda ^0}=442.9\pm 8.2(\mathrm {stat})\pm 2.8(\mathrm {syst})$$ and $$c\tau _{B^+_c\rightarrow J/\psi \pi ^+}=162.3\pm 7.8(\mathrm {stat})\pm 4.2(\mathrm {syst})$$. The measured $$\varLambda _b^0$$ polarization is $$P=0.00 \pm 0.06 (\mathrm {stat}) \pm 0.06(\mathrm {syst})$$ along with the asymmetry parameter $$ \alpha _1=0.14 \pm 0.14(\mathrm {stat}) \pm 0.10(\mathrm {syst})$$.
