Abstract The present study intended, firstly, to investigate the effect of web-integrated instruction on self-regulated learning ability in EFL writing, and secondly, to compare and contrast the effects of paper-based feedback and web-assisted feedback on the self-regulated learning ability. To this end, a quasi-experimental design was applied for both cases. In line with the first objective, ...

the aim of this study was to evaluate the effectiveness of an integrated model of emotionally focused approach and gottman model on the quality of marital relationship in married women. in this study the quasi-experimental design with pre-test, post-test and follow up with a control group were used. the study population included married women who went to tehransar health center, district 21. th...

The Stanford Satellite Systems Development Laboratory (SSDL) is currently investigating advanced satellite control technologies aimed at improved spacecraft system operations. One technique involves a unique real-time payload control strategy for satellites operating within a crosslinked constellation. This strategy effectively merges payload scheduling, traditionally considered a high level pl...

Guyana instituted a "find and treat" leprosy program in 1971 that made use of existing out-patient facilities and staff. The program, based on an integrated domiciliary approach to diagnosis, treatment, and examination of contacts, has proved successful. This article describes development of the program and discusses the prospects for control and eventual eradication of leprosy in Guyana.

In this paper the modeling of motion control system with Variable Structure System (VSS) theory using Matlab/Simulink and Caspoc is elaborated. The control is modeled in Simulink, while the power converter is modeled in Caspoc. This has advantages on both sides. Powerful toolboxes existing for Simulink can be used and the power electronics can be modeled in detail in the dedicated power electro...

The application of the sliding-mode control theory to the regulation of dc-to-dc switching converters is reviewed. Subsequently, linear dynamical models are derived and compensating networks are designed. An analog integrated circuit illustrating the theory has been designed, implemented and applied to regulate a buck converter in continuous conduction mode. Experimental verifications are provi...

Trustworthy system development entails a high nonrecurring engineering (NRE) cost together with a low volume of units over which to amortize that cost. For example, the potential for developmental and operational attacks against hardware requires countermeasures that make it very expensive to design and manufacture custom hardware used to build high assurance systems. To address these problems,...

A broader, more comprehensive concept of forest pest management is needed to make it a really integral part of forest resource management. A generalized model structure of a forest pest management system is presented, and the major components are discussed briefly. Predictive models are the primary mechanism of information flow to decision and action in the system. General considerations affect...

Figure 4 involved the analysis of chemotherapy-response signatures (as carried out independently by author AP and described in a 2006 Nature Medicine article [2,3]). It has recently been determined that the chemotherapy-response signatures in [2] are not reproducible, causing retraction of that article [3]. As such, the results presented in Figure 4 of our original paper [1] are no longer valid...
