This paper provides a complete physical picture of optical response time as a function of cell gap (d) in a wide voltage regime. Normally both rise and decay times are known to be proportional to d in the small angle approximation (Vth < V < ffiffiffi 2 p Vth), and in the high voltage regime where Vp < V < Vi the optical decay time is independent of d. In this paper, we found that between these...

We present a study analyzing the response times of users to questions on Twitter. We investigate estimating these response times using an exponential distribution-based wait time model learned from users’ previous responses. Our analysis considers several different model building approaches, including personalized models for each user, general models built for all users, and time-sensitive mode...

Wind generation is expected to reach substantially higher levels of penetration in the near future. With the converter interface, the rotor inertia of doubly-fed induction generator (DFIG) based wind turbine generator is effectively decoupled from the system, causing a reduction in inertial response. This can be compensated by enabling the DFIG to provide fast frequency response. This paper pro...

Schedulability analysis of fixed priority preemptive scheduled systems can be performed by calculating the worst-case response-time of the involved processes. The system is deemed schedulable if the calculated responsetime for each process is less than its corresponding deadline. It is desirable that the Response-Time Analysis (RTA) can be efficiently performed. This is particularly important i...

abstract: the combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. the response surface methodology (rsm) was used to determine the effect of nacl concentration (8%-20%), osmotic solution temperature (25-65°c), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 w) on water loss (wl), solids gain (sg),...

It is understandable that Security Dynamics is sensitive to any article that is critical of their SecurID card. After all, their success is based on their cus-tomers' confidence that their one-time password scheme is unbreakable. Thus, it appears to me that they read my article in Computing Systems with an overþ-sensitive eye and misunderstood some of it. In this response, I will try to clarify...

A centralized scheduler must assign tasks to servers, processing on-line a sequence of task arrivals and departures. Each task runs for an unknown length of time, but comes with a weight that measures resource utilization per unit time. The response time of a server is the sum of the weights of the tasks assigned to it. The goal is to minimize the maximum response time, i.e., load, of any serve...

| Rate Monotonic Analysis (RMA) is a well-established technique for assessing schedulability of periodic and sporadic tasks which share a processor resource using xed priority scheduling. An alternative approach to analysing such systems is to build a model which represents the behaviour of the system more dynamically, taking into account the dependency between the tasks.

This paper gives an exact analysis of mean response time of fork-join systems. The response time is shown to be the sum of parallel wait and parallel service times which are analogous to wait and service times in non-parallel systems. It is shown that the parallel service time of a job is dependent on the state at arrival time of the job. A formal parallel wait time analysis, similar to the wai...
