    Barrow Holographic Dark Energy in Extended Teleparallel Theories of Gravity
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2021) Ghulam Murtaza; CIIT/FA19-RMT-085/LHR; Dr. Shamaila Rani; LHR TP 7424
    In this thesis, we reconstruct some solutions in the context of telepar- allel based extended theories coupled with trace of energy-momentum ten- sor, boundary term and Gauss-Bonnet term. For this purpose, we ob- tain the effective energy density and pressure for these theories for flat FRW universe model. The reconstruction is made through the compari- son of these effective energy densities with the energy density of Barrow holographic dark energy model. In this regards, we use scale factor in terms of power-law form and find some gravitational Lagrangian functions as f(T ) = T +g(T ), f(T, τ ) = T +γh(τ ), f (T, τ ) = βτ +g(T ), f(T, TG) = TGg(T ), f(T, TG) = −T + TGg(T ), f(T, TG) = TG + g(T ), f(T, TG) = T + j(TG), f(T, B) = T + σy(B) and f(T, B) = B + ξg(T ). In order to discuss the cosmic analysis related to these models, we plot equation of state parameter for each model. We investigate the squared speed of sound parameter for these models to determine the stability of the models. We obtain some favorable results related to specific values of model parameters.

    Creative apparel Pvt Ltd.
    (Library Information Services, COMSATS University Islamabad, Lahore Campus., 2023-11-20) Ghulam Murtaza; FA20-BBA-034; Imran Ur Rehman
    I joined Creative Apparels Pvt. Ltd as an internee. The motive of joining the Company was to have exposure to the knitwear manufacturing industry and get a sound knowledge about its workings. I devoted my time to learning about Creative Apparel Company, as it will be helpful if I ever join the knitwear or textile industry. In this internship program, I attended the lectures of key departments like IE (Industrial Engineering), PPC (Production Planning and Control), GGT (Garber Garment Technology), and the export department of this knitwear manufacturing firm as well as I also visited these departments for practical knowledge. The objective I placed in this report is state what I observed and learned the measures and steps that are necessary and help in achieving the goals of the company. Creative Apparel Pvt. Ltd is an esteemed Design-Manufacturer-Exporter of Knitted Garments, established in 2003. It is a cut-to-pack garments manufacturing facility. Creative Apparel has several years of experience and accomplishments, the company is now a leading competitive knitwear manufacturing organization in Pakistan having the capacity to produce up to 20,000 garments a day and garments export consisting of 70% to Europe and 30% to the USA.
