Sri Guru Granth Sahib World University is a private university located in Fatehgarh Sahib, Punjab, India. It was established under Punjab State Act 20/2008 .The construction of the building was funded by the Shiromani Gurudwara Prabandhak Committee. The university was inaugurated formally and started its first session on 24 July 2011. Though Jasbir Singh Ahluwalia was appointed the first Vice-Chancellor of the university in 2008, he was shot and critically injured only few days after inauguration of the university. Gurnek Singh, former head of the Department of Sri Guru Granth Sahib Studies, Punjabi University was appointed acting Vice-Chancellor of the university on 9 August 2011.A distinguishing feature of the University will be Sri Guru Granth Sahib Studies characterized by latest interpretational methodologies, Sikh Historiography with re-interpretation, in contemporary ideological perspective, of the basic sources will be given special attention. The new university would also focus on imparting education in most modern technologies such as nano-technology, bio-technology, information technology and business management besides comparative study of different religions. The university would also house faculties of schools of emerging technologies, basic science, management, social science, arts, languages, engineering, architecture, law and social justice.

With the aim of designing long-haul, back-to-back, and amplitude-phase-modulated optical OFDM systems, we carry out a simulative analysis for averaging the optimum value of the relative intensityto- noise ratio (RIN). We find that for single-mode lasers a bias of 2 mA has the highest spurious-free dynamic range (SFDR) and low RIN, and for multimode lasers, a bias of 6 mA has the highest SFDR and low RIN. © 2012 Springer Science+Business Media New York.

A new coding scheme is proposed using a variable rate for an all-optical sampling orthogonal frequency-division multiplexing system, to minimise the peak-to-average power ratio. cyclic rotation and code rate variation are shown to improve the peak envelope power. the proposed idea comprises of searching for a variable code rate selection for the binary input data and cyclic rotation, followed by codeword inversion. © The Institution of Engineering and Technology 2012.

Orthogonal rotation invariant moments (ORIMs) are among the best region based shape descriptors. Being orthogonal and complete, they possess minimum information redundancy. The magnitude of moments is invariant to rotation and reflection and with some geometric transformation, they can be made translation and scale invariant. Apart from these characteristics, they are robust to image noise. These characteristics of ORIMs make them suitable for many pattern recognition and image processing applications. Despite these characteristics, the ORIMs suffer from many digitization errors, thus they are incapable of representing subtle details in image, especially at high orders of moments. Among the various errors, the image discretization error, geometric and numerical integration errors are the most prominent ones. This paper investigates the contribution and effects of these errors on the characteristics of ORIMs and performs a comparative analysis of these errors on the accurate computation of the three major ORIMs: Zernike moments (ZMs), Pseudo Zernike moments (PZMs) and orthogonal Fourier-Mellin moments (OFMMs). Detailed experimental analysis reveals some interesting results on the performance of these moments. © 2013 Springer Science+Business Media New York.

Purification techniques like ozonization, chlorination and filtration have their own limitations of corresponding energy sources and harmful waste generation. However, heterogeneous photo catalysis is used for producing oxidative agent (hydroxyl radical) which has been used as an environmentally harmonious decontamination process. Such safe and low energy consumable photo catalytic system is required for purification of polluted water. Degradation of dyes is a standard method to check the photocatalytic activity of any type of photo catalyst. In this paper thioglycerol capped and uncapped ZnS nanoparticles are studied in detail for their photocatalytic activity and generation of electron hole pairs. Bromophenol blue, crystal violet and reactive red dyes were successfully photo reduced using ZnS nanoparticles after 3.0. h of irradiation. Since the photocatalytic activity depends on the generation of electron hole pairs and the existence of different phases, we have tried to correlate the optical and morphological studies with these results to understand the phenomenon of photocatalytic activity at nanoscale. Though the Ultra violet irradiation can efficiently degrade the dyes, naturally abundant solar radiation is also very effective in the mineralization of dyes. Hence, it may be a viable technique for the safe disposal of textile wastewater into the water streams. © 2011 Elsevier Ltd.

Mn (0.5%, 1%, 1.5% and 2%) doped and undoped ZnO nanoparticles (NPs) capped with PVP (1.0%) were successfully synthesized via co-precipitation approach using zinc acetate, sodium hydroxide and manganese acetate as precursors. Structural analysis was performed by XRD confirming phase purity and crystalline wurtzite structure. TEM results show average particle size 15-20 nm and 22-25 nm for Mn (1%) and Mn (2%) doped ZnO NPs respectively. Manganese (Mn) doping has led to reduction in band gap which facilitate the absorption of radiation in visible region. The Photocatalytic activity of undoped and Mn (0.5%,1%,1.5% and 2%) doped NPs was analyzed via degradation of crystal violet (CV) dye. The crystal violet decomposition rate of undoped and Mn doped NPs were studied under UV-visible region. It is observed from degradation studies that the doping has a pronounced effect on the photocatalytic activity of ZnO NPs. Kinetic studies shows that photo degradation of CV follow a pseudo first-order kinetic law. Experiments for reusability of Mn (1%) doped with PVP (1%) capped ZnO were also performed to determine the stability of as prepared sample. It shows an increase in catalytic activity of NPs by small amount when exposed to UV irradiation for 3 h. Photoluminescence and UV-Visible absorption spectroscopy studies were also performed for studying the effect of UV irradiation on the surface of ZnO NPs.
