Self-reconfigurable modular robots consist of multiple elements and have the potential to enable future autonomous systems adapt themselves handle unstructured environments, novel tasks, or damage their constituent elements. This paper considers methods self-assembly, bringing together robotic modules form larger organism-like structures, self-repair, removing replacing faulty damaged by intern...

Self-repair robots are modular robots that have the capability of detecting and recovering from failures. Typically, such robots are unit-modular and carry a number of redundant modules on their bodies. Self-repair consists of detecting the failure of a module, ejecting the bad module and replacing it with one of the extra modules. In this paper we show how self-repair can be accomplished by se...

This study was conducted to investigate the effect of meaning-focused versus form-focused input-oriented and output-oriented task-based instruction on elementary level Iranian EFL Learners’ vocabulary comprehension and recall. For this purpose, a sample of 120 male students from a private school in Tehran was selected through convenience sampling and based on availability. The participants were...

in this study, coping strategies, perceived self efficacy , and attitude of two groups of normal and neurotic persons toward stressful lfe events were investigated, the normal group included 104 individuals and the neurotic group consisted of 40 patients. copuyning streategies, perceived self-efficacy, and attitude toward life events questionnaired were used inthis study.the findings indicated ...

Phase clocks are synchronization tools that implement a form of logical time in distributed systems. For systems tolerating transient faults by self-repair of damaged data, phase clocks can enable reasoning about the progress of distributed repair procedures. This paper presents a phase clock algorithm suited to the model of transient memory faults in asynchronous systems with read/write regist...

LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. List five principles that guide synchronous repair of bilateral complete cleft lip and nasal deformity. 2. Explain how different growth rates for the principal nasolabial features are applied during primary repair. 3. Describe two approaches for positioning the alar cartilages to form the columella. 4. Discus...
