The Ministry of Agriculture (MoA) in Iran, considered the necessity of e-learning in agricultural extension for training extension agents as human resources that are working in extension centers throughout the country and have direct interaction with farmers, because they understand that traditional education is no longer effective. As a result, understanding challenges for e-learning in Iran’s...

This paper presents a profit-oriented shift scheduling approach for inbound contact centers. The focus is on systems in which multiple agent classes with different qualifications serve multiple customer classes with different needs. We assume that customers are impatient, abandon if they have to wait, and that they may retry. A discrete-time modeling approach is used to capture the dynamics of ...

Motivated by practices in customer contact centers, we consider a system that offers two modes of service: real-time and postponed with a delay guarantee. Customers are informed of anticipated delays and select their preferred option of service. The resulting system is a multiclass, multiserver queueing system with state-dependent arrival rates. We propose an estimation scheme for the anticipat...

Extension assertion construct Justification: The question arises whether extension assertion constructs are necessary. After all, many Hardware Verification Languages (HVLs) provide powerful language features that can be used to describe correct temporal behavior. These HVLs can be used for data generation and results analysis thru temporal specification. In addition, the Accellera Formal Verif...

W consider large contact centers that handle two types of jobs—inbound and outbound—simultaneously, a process commonly referred to as call blending. Inbound work arrives to the system according to an exogenous arrival process, whereas outbound work is generated by the contact center. We assume that there is an infinite supply of outbound work to process, and that inbound calls are prioritized o...

Organizations worldwide use contact centers as an important channel of communication and transaction with their customers. This paper describes a contact center with two channels, one for real-time telephone service, and another for a postponed call-back service offered with a guarantee on the maximum delay until a reply is received. Customers are sensitive to both real-time and call-back delay...

The Polygonal Contact Model or PCM is originally an algorithm for contact analysis between rigid bodies with complicated geometries in multibody dynamics. In applications where the flexibility of contacting bodies is not negligible, rigid body contact modeling can not achieve realistic results and elastic body contact modeling should be utilized instead. Therefore, due to the importance and nec...

Canola producers in the Province of Qazvin were surveyed in order to explore their perceptionabout technical skills influencing the production of canola. Based on the perception ofrespondents, the results showed that the contact with agricultural service centers would encouragefarmers to produce canola. The results showed that there were relationship between perception ofrespondents about canol...

the process of collection development, collection generating and obtaining information is of basic debates in libraries and information centers which a lot of articles have been written about the methods of collection development of information as well as the application of information technology, accordingly, to this day. this article, as opposed to other articles, which are about the prevaili...
