This research work studies several forecasting techniques to predict future income generation and its
implications on the Nissan Urvan income generation in Anambra State Transport sector .This paper presents three
forecasting models (time series decomposition method, winter’s method and Arima method) to analyze data income
generation of Anambra State Transport Sector over the period of 2005-2019, it is important to know the trend in
Anambra Transport Sector to elicit patterns of incomes generated. However, the models used were based on applicable
methodology to facilitate accurate and faster analysis of data. The results reveal that the future income generated for the
products will continuously decrease with time. Having observed the values obtained from the models used, it is
recommended that the company should employ time series decomposition forecasting model because it gives more
accurate result with less error.

In the era of World Wide Web, more than one billions of websites are active over the internet. To perform the
log analysis on huge number of available websites, although, numerous featured log analysis tools are existing. However,
the great difficulty arises in selection of suitable tools. This work provides an investigation of open source and
commercial toolsets available for the analysis the study will provide many choices to pick from when deciding a toolset
to manage and analyze log data. The paper will help to review the set of tools currently available and positively hook the
right tool to get started on analyzing logs in their organization.

Friction stir welding (FSW) is proved as a promising welding technology for joining dissimilar aluminium
alloys. Aluminium alloys are used extensively within the aerospace industry for applications such as fuselage and wing
skin panels due to their high strength to weight ratio. Therefore, an attempt is made to optimize the process parameters of
friction stir welding using AA2024 and AA6061 age hardenable aluminum alloys in order to improve the tensile
properties such as ultimate tensile strength (UTS) and tensile elongation (TE). A response surface method (RSM) based
fuzzy grey relational approach (Fuzzy - GRA) is applied using four factors with three levels. The process parameters
namely rotational speed (N), welding speed (F), axial load (P) and pin shape (PS). The results indicate a RSM based
fuzzy grey relational approach improving tensile properties of FS welded AA2024 and AA6061 aluminum alloys when
comparing to conventional grey relational approach. A quadratic relationship was also established between the process
parameters and fuzzy grey relational grade.

The optimum self-focussing materials with an intensity-dependent refractive index and the realization of the
ability of these materials to produce intensity dependent phase shift in all-optical photonic devices have become a topic
of continuous investigation. Many organic materials including dye-doped polymer films are creating interest due to their
advantages in terms of enhanced efficiency, and optimum mechanical properties to fabricate reliable devices. In this
paper, we have studied the nonlinear optical properties like nonlinear absorption and nonlinear refraction of a two-photon
fluorescent dye DASPB doped in Polymethyl methacrylate-methacrylic acid (PMMA-MA) polymer matrix using open
aperture and closed aperture Z-scan experimental methods by means of low power continuous wave (CW) laser beam.
The optical limiting properties of these films are also studied using Type 1 and Type 2 configurations at different input
powers using continuous wave (CW) laser beams of 532 nm wavelength. The nonlinear refractive index n2, nonlinear
absorption coefficient β, changes in refractive index with input intensity, and the magnitude of third-order optical
nonlinearity of the dye-doped film are experimentally determined. The saturated output power for type 1 and type 2
optical limiting are determined. The input limiting threshold and saturated output power level for both type 1 and type 2
optical limiting configurations are recorded. DASPB dye-doped in PMMA-MA polymer film has shown saturation
absorption at lower input irradiance and reverse saturation absorption along with two-photon absorption at higher input
irradiance and hence found to be a potential candidate for the third harmonic property based photonic devices.

This report describes an intelligent street lighting system with integrated solar energy resources and mobile
application. Based on the rate of 0.45 fils/KW.hr (fils-UAE currency subdivision), it cost AUS (American University of
Sharjah) AED 373,852 per annum (AED-UAE currency)due to the usage of conventional high-pressure sodium lamps in
their street lighting. In our project, the proposed solution is to replace all of the conventional lamps with LED (Light
Emitting Diode) lamps in AUS and then control them using motion sensors and further develop a mobile application,
using which we can control the switching ON/OFF of the LEDs and at the same time check for defected unit. Solar
radiation energy is used to charge the battery during daytime, and offer energy to the LEDs light equipment at night. A
dimmable Modula is designed and integrated to the system to dim the LEDs at night from 01:00-06:00am. This system
has a double advantage- it utilizes renewable energy and also reduces cost.
