this nature to determine if this software detects differences in gas/water fluid flow
behavior and optimize the production from well. For the main modeling work, the
software package PROSPER will be used, as it is...
Abstract—The paper unfolds a methodology for compression of real time images received from the on-board satellite cameras sing the JPEG2000 image compression algorithm).It will enable the satellite image data to be transmitted much quickly and will help in efficiently utilizing the available bandwidth. The JPEG2000 compression scheme was chosen due to its better compression capability as well...
This research proposes a model that is able to approximate unsteady flows in rivers and simulate the associated riverine processes to gain an understanding and insight into open-channel flow dynamics. The governing equations include Saint-Venant equations. Second-order temporal and spatial accuracy is obtained by TVD Runge-Kutta method and high resolution reconstruction techniques,...
This paper analyzed the widely-used access management treatment in Rawalpindi/Islamabad, Pakistan: using U-turn instead of traffic signal or direct right turn. Data was collected from a very congested traffic signal at Khanapul traffic signal, Islamabad Expressway. The traffic signal was recently closed and traffic was diverted to U-turns placed at downstream. No of accident and their severity...
The seismic hazard at a site can be well quantified in term of fault rupture mechanism and site effect on seismic stress waves propagation. The input ground motion is an important parameter for the seismic characterization of ground response analysis and engineering structures. The presence of several active reverse faults in the vicinity of Peshawar Metropolitan city makes it vulnerable to...
Depletion of natural energy resources and environmental pollution are challenging global issues. Renewable fuels such as solid biomass emerged as a promising candidate to cope with issues of fossil fuels. Gasification is one of popular thermal treatment route to convert biomass into bioenergy at high temperature. Producer gas, biochar, and bio-oil are main products of gasification reaction....
Proton exchange membrane fuel cells (PEMFC) are attractive alternative source of electricity. The current study involves the computational fluid dynamics simulations of PEMFC under isothermal and non-isothermal conditions to investigate the performance of fuel cell. Effect of pressure and temperature on fuel cell performance has been studied under non-isothermal conditions. PEMFC has been...
This work examines the efficiency a microgrid for parallel multiple voltage source inverters. One of the inverters is traditional VSI inverter, whilst the other inverter is a VSG based inverter for battery storage. Battery inverter. The stability of a PV-BESS microgrid is a bit more challenging than ordinary microgrid. Rather than finding the ration of the impedances of inverters and terminal...
ABSTRACT
Environmental contamination is the major issues associated with rapid increase in the by product and waste generated from industries, domestic and other daily life activities. Solutions to reuse and incorporate waste (electronic waste, ceramic waste, and lathe machine scrape waste) can be rewarding for many reasons, specifically for environmental, economic and technical aspects. In...
Leaving waste materials to the environment can cause environmental problems. Sustainability in concrete production can be achieved by innovations in substitution of materials used, which are much needed to meet the increasing demand for new and quality materials. To that end, this study is aimed at utilizing Waste marble powder and Stone dust as partial replacement of cement and fine aggregate...
The durability of concrete one of the most significant problems within the civil engineering community. Through careful design and the durability and long term performance of many concrete structures enhance by the use of Engineered Cementitious Composite (ECC) also known as High Performance Fiber Reinforced Cementitious Composite (HP-FRCC) or Benable Concrete. However, before implementing...
Effective selection and design improvements of materials in surface engineering and tribological applications require knowledge of their near-to-surface mechanical properties. A better understanding and control of the surface mechanical properties of polymers is required for their optimal use as engineering materials. This is particularly important when these materials are used to improve the...
Abstract:Spherical gold (Au) nanoparticles are prepared by hydrothermal method and are characterized by ultra violet visible spectroscopy is revealed the size of chemically synthesized gold nanoparticles as 5_10nm and X_ray diffactromtery(XRD) analysis determine the polycrystalline nature of gold nanoparticals and scanning electron microscopy.For antimicrobial activity and high surface...
Due to their predefined size and shape, nanoparticles have gained much attention for material development in daily life applications. In textile industry, the modifying of conventional textile is required that can alter the entire property of the textiles. Therefore, it was need to develop a fabric which is antimicrobial and self-cleaning as well as protective against UV-irradiation without...
Nigeria, like any other developing country, considers the construction industry as one the main contributors to its Gross Domestic Product (GDP). However, there are unresolved issues arising from the ongoing and widespread adoption of the traditional method of construction such as; poor workmanship, delays in production and delivery time, unnecessary wastages and lack of sustainability...
As concrete is one the construction material extensively used throughout the world so it also makes water to be one of the material widely used in the concrete industry. With the current water crises situation in Pakistan specifically in Balochistan, there is a need to look for alternative sources of water for concrete making, as potable water is not completely available even for drinking purposes.
Marble powder/sludge is an industrial waste resulting from cutting, shaping and polishing of Marble. Industrial waste management is one of the major environmental problems, therefore, recycling and reuse of industrial wastes will play vital role both in resolving industrial waste problem and in getting benefit from it. Utilization of marble dust/sludge in the production of new building...
This research was implemented to develop and to determine that how much self-weight of concrete decreases with the increase of Lightweight Aggregate and what its effect on the strength.
