In this paper, we present a new iterative method with order of convergence eighth for solving nonlinear equations. Periteration this method requires three evaluations of the function and one evaluation of its first derivative. A general error analysis providing the eighth order of convergence is given. Several numerical examples are given to illustrate the efficiency and performance of the new ...

Passage of the Workforce Investment Act (WIA) has focused policymakers’ attention on measuring the performance of employment and training programs. Explicit performance measures can provide timely information to policymakers and program operators for assessing and improving their policies and programs. Under WIA’s predecessor, the Job Training Partnership Act (JTPA), policymakers relied on two ...

Student evaluations of faculty are important components of the medical curriculum and faculty development. To improve the effectiveness and timeliness of student evaluations of faculty in the physiology course, we investigated whether evaluations submitted during the course differed from those submitted after completion of the course. A secure web-based system was developed to collect student e...

Previous research has demonstrated that system performance does not always correlate positively with user performance, and that users often assign positive evaluation scores to systems even when they are unable to complete tasks successfully. This paper investigates the relationship between actual system performance and users’ perceptions of system performance by manipulating the level of perfo...

A push-pull ventilation system is effective for hazardous material exhaustion. Although a push-pull ventilation system has advantages over a local exhaust hood, some laborious adjustments are required. The pertinence of the adjustments is uncertain because it is difficult to evaluate the performance of a push-pull ventilation system quantitatively. In this study, a measurement of the capture ef...

A wide variety of network applications require the use of reliable multicast protocols to disseminate data from one source to a potentially large number of receivers simultaneously. Broadband satellite is an ideal transmission medium to support such applications. Although several reliable multicast protocols have been proposed for the Internet, they are not optimized for satellite networks, and...

For wireless sensor networks a wide variety of adhoc routing algorithms are available in the literature. Typically, each algorithm comes with its own platform and application scenario, which makes it hard to compare different routing algorithms. In this paper we introduce a high level simulation environment, which provides a fast and easy way for routing performance evaluations. PROWLER, a prob...

Mobile nodes in some challenging network scenarios, e.g. battlefield and disaster recovery scenarios, suffer from intermittent connectivity and frequent partitions. Disruption Tolerant Network (DTN) technologies are designed to enable communications in such environments. Several DTN routing schemes have been proposed. However, not much work has been done on designing schemes that provide effici...

The performance of today’s enterprise applications is influenced by a variety of parameters across different layers. Thus, evaluating the performance of such systems is a time and resource consuming process. The amount of possible parameter combinations and configurations requires many experiments in order to derive meaningful conclusions. Although many tools for automated performance testing a...

The authors explored the validity of two perspectives as to how managers evaluate subordinates who resist downward influence attempts: a uniformly dysfunctional perspective (i.e., managers regard all manifestations of resistance as indicators of ineffective influence and rate subordinates unfavorably when they resist) and a multifunctional perspective (i.e., managers regard some manifestations ...
