Off-road cars’ windshields are vulnerable to different types of stones, road debris and pebbles due to common off paved and gravel surfaces in which they drive. Any attempt to design windshield that minimizes injury and death of occupants during a vehicle accident requires a thorough understanding of the mechanical behavior of automotive windshield subjected to foreign object impact loads...

FLEXIBLE ELECTRONICS ARE emerging as an alternative to conventional silicon electronics for large-area, low-cost applications such as rollable displays and TVs, e-papers, smart sensors, and disposable RFID tags. Through inexpensive manufacturing methods (e.g., ink-jet printing and roll-to-roll imprinting), flexible electronics can be printed on low-cost plastics. This advantage makes flexible e...

Effective parameters that can effect on the performance of the separation system consist of operating pressure, operating temperature, reflux ratio, and kind of produce desirable products and different sequences of splits. As take a separation system with optimal performance is dependent on optimization of above mentioned effective parameters. In generally, there are two criteria (as object fun...

In this study, we apply a weighted sensitivity approach to topology optimization analysis based on the density method in dynamic oscillation problems. our proposed technique, strain energy is employed as performance function. The self-adjoint relation derived from energy. However, when using properties of mesh prevent acquisition non-oscillatory distribution. Employing sensitivity, however, red...

Building information modeling can help in predicting the energy efficiency in future based on dynamic patterns obtained by visualization of data. The aim of this study was to investigate the effective parameters of energy consumption using BIM technology which can evaluate the buildings energy performance. First, three forms of general states in the building were modeled to evaluate the propose...

In present study, the effects of optimization on seismic energy spectra including input energy, damping energy and yielding hysteretic energy are parametrically discussed. To this end, 12 generic steel moment-resisting frames having fundamental periods ranging from 0.3 to 3s are optimized by using uniform damage and deformation approaches subjected to a series of 40 non-pule strong ground motio...

The Cloud Computing model leverages virtualization of computing resources allowing customers to provision resources on-demand on a pay-as-you-go basis. During recent years, the power consumption of datacenters in cloud environment attracted researchers. Optimization of energy consumption can be performed by different methods including virtual machine (VM) consolidation. This technique can reduc...

increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...

This paper presents an optimization study of a lightweight hinge consisting of a thin walled tube made of carbon fiber reinforced plastic with two longitudinal slots. The slot geometry is parameterized in terms of slot length, width and end circle diameter. Previously developed numerical simulation techniques to analyze the folding and deployment of this kind of hinges are used to carry out a s...
