Multiplication is a basic operation in any signal processing application. Multiplication is the most important one among the four arithmetic operations like addition, subtraction, and division. Multipliers are usually hardware intensive, and the main parameters of concern are high speed, low cost, and less VLSI area. The propagation time and power consumption in the multiplier are always high. ...

Joint analysis of longitudinal measurements and survival data has received much attention in recent years. However, previous work has primarily focused on a single failure type for the event time. In this paper we consider joint modelling of repeated measurements and competing risks failure time data to allow for more than one distinct failure type in the survival endpoint which occurs frequent...

In studies with multiple endpoints, such as cancerspecific mortality and noncancer-specific mortality, conventional statistical approaches evaluate these endpoints using a separate Kaplan-Meier analysis without considering whether these endpoints are competing events for each other. In our recent study, we examined the influence of increasing age on lung cancer-specific and noncancerspecific mo...

Product development is often performed by functionally and geographically distributed groups of people. In such an environment, there are many concerns that must be traded off against one another before a product can be brought to market. An example of this tradeoff is high performance versus low cost; a product with high performance generally costs more than a product with low performance. Whe...

Unlike single microphone techniques for voice activity detection (VAD), multi-microphone signal processing usually exploits the spatial information of signals received at multiple microphones. In this paper, we propose a VAD algorithm based on conic constraints to achieve robustness against the direction of arrival (DOA) estimation error. The proposed algorithm uses the phase vector as feature ...
