In this paper, a novel analytical method was developed based on statistical energy analysis framework to evaluate sound transmission loss through ventilated windows. The proposed method was compared to numerical and analytical models available in the literature. Results showed the success and advantage of the proposed model in predicting the acoustic performance of the ventilated window and the...

69 INTRODUCTION The success of operating a drive-thru facility depends on queues and waiting times experienced by customers. Drivethru facilities are required to provide queuing areas that can hold the expected maximum queue length. Rates of arrivals and service times affect the required queuing areas for drive-thru facilities. Gattis recommended queuing areas for drive-thru facilities located ...

Existing backoff scheme’s optimization of IEEE 802.11 DCF MAC protocol consider only saturated networks or asymptotic conditions. In real situations, traffic is bursty or streamed at low rates so that stations do not operate usually in saturated regime. In this work, we propose and analyze a backoff enhancement for IEEE802.11 DCF that requires information only about the network size and that is...

We present an operating system independent and tamper-resistant worm-containment end-system. This system continuously observes outgoing network traffic over a finite-duration traffic window, and using heuristic rules executing in a secondary environment, detects infections. It automatically quarantines the infected host to stop further spread of the worm. We present four heuristic rules, and us...

This paper focuses on the binary analysis of the center-weighted median (CWM) filters. This subclass of nonlinear stack filters is based on minimal positive Boolean functions (PBFs), the complexity of which depends on two parameters only, such as a window size and a weight of the central sample. It can be easily seen that the complexity of PBFs corresponding with CWMs increases with the increas...

The stability and performance of nanoscale junctions are closely related to the local effective temperature. The local effective temperature is mainly caused by the competition between heating and cooling processes in inelastic electron-phonon scat- tering. Local cooling occurs when the rate of energy in cooling exceeds that in heating. Previous research has been done using either specific pote...

• Building energy analysis using smart and static windows were performed in Oman. Electrochromic better while Daylight illuminance control was applied. PDLC sandwiched between silver coated glass even than EC. Worldwide consumption CO 2 emissions increase yearly the building industry contributes most out of all other sectors. The residential sector provides largest portion consumption. Reducing...

We consider a variety of dynamic, hardware-based methods for exploiting load/store parallelism, including mechanisms that use memory dependence speculation. While previous work has also investigated such methods [19,4], this has been done primarily for split, distributed window processor models. We focus on centralized, continuous-window processor models (the common configuration today). We con...

Signal segmentation is a crucial stage in the activity recognition process; however, this has been rarely and vaguely characterized so far. Windowing approaches are normally used for segmentation, but no clear consensus exists on which window size should be preferably employed. In fact, most designs normally rely on figures used in previous works, but with no strict studies that support them. I...
