many new technologies have been employed to improve welfare conditions and to provide an optimum utilization of the existing resources in agriculture sector. laser leveling technology is one of the most progressed in maintenance of soil and water resources which itself has an important role in sustainable development. the purpose of this study was to realize the specifications of adopters vs. n...

Detecting races is important for debugging shared-memory parallel programs, because the races result in unintended nondeterministic executions of the programs. Previous on-they techniques to detect races have a bottleneck caused by the need to check or serialize all accesses to each shared variable in a program that may have nested parallelism with barrier synchronization. The new scalable moni...

Conventional semantics for shared-variable concurrency suffers from the “grain of time” problem, i.e., the necessity of specifying a default level of atomicity. We propose a semantics that avoids any such choice by regarding all interference that is not controlled by explicit critical regions as catastrophic. It is based on three principles: – Operations have duration and can overlap one anothe...

Multi-replicA decoding using correlation baSed LocAlisAtion (MARSALA) is a recent random access method for satellite communications. It follows the multiple transmission and interference cancellation scheme of Contention Resolution Diversity Slotted Aloha (CRDSA). Besides, at the receiver side, MARSALA uses autocorrelation to localise replicas of a same packet so as to combine them. This signal...

background : managers’ communication skills are one of the most important topics in educational sector of universities of medical sciences and may have considerable effect on faculty members and employees. this study was performed to determine the level of communication skills (verbal, listening, feedback) of the heads of department of faculties and its relation with some demographic variables....

Oral Communication Strategies are conscious techniques that L2 interlocutors employ to overcome the communication breakdowns in the target language. Hence, they can help to promote the effectiveness of communication ability. However, it must be noted that many variables can influence the use of these strategies. The present study, therefore, aimed to investigate the role of language proficiency...
