the present research work was carried out to assess the relationship between outreach services of a faculty member, and his academic tasks of teaching performance and research productivity. a number of 95 faculty members from the colleges of agriculture and natural resources constituted the statistical population of the study. a questionnaire was employed for collection of data on outreach serv...

Waiting time and system time (waiting plus service time) data, adjusted for idle times when necessary, are used for estimating the parameters in GI/G/1 queues. The sampling plans presented use incomplete information on the differences between service and inter-arrival times rather than full information on service and inter-arrival times. A variation of the EM algorithm is proposed to derive par...

One of the most challenging issues of service–centric software engineering is the QoS–aware composition of services. The aim is to search for the optimal set of services that, composed to create a new service, result in the best QoS, under the user or service designer constraints. During service execution, re-planning such a composition may be needed whenever deviations from the QoS estimates o...

Environmental performances of electricity generation, expressed as environmental impacts per kWh of electricity produced, depend strongly on technical, methodological and geographical parameters. When considering the global environmental performances of renewable energies, a geo-dependent life cycle assessment (LCA) taking into account geographical issues is of high interest. To illustrate this...

Taguchi’s parameter design approach offers a step by step methodology for optimization of various parameters with regard to performance, quality and cost [1]. The quality of design may be enhanced by enhancing the quality and productivity in different organization-wide performances. Those performances concerned with quality incorporate in quality of product planning, product design and process ...

The synthesis of mixed-component metal-organic frameworks (MOFs) –including multivariate MOFs (MTV-MOFs), multicomponent MOFs, mixed-metals and mixed-ligands metals MOFs– is becoming a very active research field. This mainly based on the unique possibilities these materials offer to incorporate multiple functionalities in how this heterogenity complexity translated unexpected properties, which ...

The present paper joins within the framework of research to optimize the Quality of Service (QoS) in the Mobile Ad Hoc Networks (MANET). In this paper, we have studied the impact of real-time VBR (H.263) traffic on the performances (End-toEnd Delay, Throughput and Packet Delivery ratio) of routing protocols DSDV (Dynamic DestinationSequenced Distance-Vector) and AODV (Ad Hoc On-Demand Distance-...

Smart Cities draw a nice picture of a connected city where useful services and data are ubiquitous, energy is properly used and urban infrastructures are well orchestrated. Fulfilling this vision in our cities implies unveiling citizens data and assets. Thus, security and data privacy appear as crucial issues to consider. In this paper, we study a way of offering a secured energy management ser...

Nowadays high fuzzy utility based pattern mining is an emerging topic in data mining. It refers to discover all patterns having a high utility meeting a user-specified minimum high utility threshold. It comprises extracting patterns which are highly accessed in mobile web service sequences. Different from the traditional fuzzy approach, high fuzzy utility mining considers not only counts of mob...

this paper presents a new formulation for warehouse inventory management in a stochastic situation. the primary source of this formulation is derived from fp model, which has been proposed by fletcher and ponnambalam for reservoir management. the new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. using this model, the expected value...
