The pull request mechanism is commonly used to propose source code modifications and get feedback from the community before merging them into a software repository. On GitHub, practitioners can provide on by either commenting or simply reacting it using set of pre-defined GitHub reactions, i.e., “Thumbs-up”, “Laugh”, “Hooray”, “Heart”, “Rocket”, “Thumbs-down”, “Confused” “Eyes”. While large num...

As strategically important determining possibility realizing leadership in national educational space with regard to environment, implementation new projects training process for specialists basic competences is considered.

The verbs གསོལ་ gsol `request' and གནང་ gnaṅ `agree, grant', because of theircomplementary semantics parallel syntax, provide a convenient windowthrough which to caste light on the two forms subordinate clausesthat they both govern, namely infinitives terminative verbal nouns.

Medical imaging has a remarkable role in the practice of clinical medicine. This study intends to evaluate the knowledge of indications of five common medical imaging modalities and estimation of the imposed cost of their non-indicated requests among medical students who attend Shiraz University of Medical Sciences, Shiraz, Iran. We conducted across-sectional survey using a self-administered qu...

Today, the use of the Internet and Internet sites has been an integrated part of the people’s lives, and most activities and important data are in the Internet websites. Thus, attempts to intrude into these websites have grown exponentially. Intrusion detection systems (IDS) of web attacks are an approach to protect users. But, these systems are suffering from such drawbacks as low accuracy in ...

As deployed Grids increase from 10s to 1000s of nodes, the construction of an efficient and scalable information system is a key issue, as it is vital for providing querying and discovery services. Today most Grids adopt a centralized or hierarchical model for their information system, but this model is characterized by poor scalability, resiliency and load-balancing features. Nowadays the rese...

Reducing response time is a primary focus of computer systems research. One key factor that influences a job’s response time in a multi-server system is dispatching: when a job arrives to the system, it must be sent immediately to one of the servers. This thesis focuses on a new dispatching policy: redundancy. Unlike traditional dispatching policies, which send only a single copy of each job, t...

We consider a generic online allocation problem that generalizes the classical online set cover framework by considering requests comprising a set of elements rather than a single element. This problem has multiple applications in cloud computing, crowd sourcing, facility planning, etc. Formally, it is an online covering problem where each online step comprises an offline covering problem. In a...

This paper considers vehicle routing problems (VRP) where customer locations and service times are random variables that are realized dynamically during plan execution. It proposes a multiple scenario approach (MSA) that continuously generates plans consistent with past decisions and anticipating future requests. The approach, which combines AI and OR techniques in novel ways, is compared with ...
