The effectiveness of Variable Messages Signs (VMS) on route guidance is assessed by a discrete probit choice model that estimates the proportion of vehicles that diverts to an alternative routes given the characteristics of different messages. A before–and–after study is also conducted to quantitatively evaluate the network wide reduction of travel time and total delay of VMS systems. We find t...

The effect of motexafin gadolinium (MGd), a redox mediator, on tumor response to doxorubicin (Dox) and bleomycin (Bleo) was investigated in vitro and in vivo. MES-SA human uterine sarcoma cells were studied in vitro using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide viability assay. Rif-1, a murine fibrosarcoma cell line, was studied using a clonogenic survival assay. Tumor gr...

This paper deals with digital processing of speech as it pertains to the hearing impaired. The issues described in this paper deal with the development of a true real-time digital hearing aid. The system (based on Texas Instruments TMS320C3X) implements frequency shaping, noise reduction, , interaural time delay, amplitude compression and various timing options. It also provides a testbed for f...

Two of the major challenges in networked haptic telepresence and teleaction systems are the time delay associated with the data transmission over the network and the limited communication resources. Sophisticated control methods are available for the stabilization in the presence of time delay. The reduction of haptic network traffic, however, is only poorly treated in the known literature. Dat...

ABSTRACT:The main objectives of any VLSI design are to achieve the low Power, minimum Delay and Area reduction. Minimizing power, delay & area is a challenge in the present situation, but all efforts to achieve one of these can lead to a better design. This paper proposes an EDA tool for low power/ high speed VLSI design, which solves any DFG to estimate the speed of operation and the percentag...
