The study was carried out at Agarfa ATVET College dairy farm to evaluate the reproductive performance of Holstein Friesian× Arsi and Holstein Friesian ×Boran cattle. For the study, records compiled from 1983 to 2012 at the Agarfa dairy farm were used as original data. The effects of breed, bloodlines, season and parity on the reproductive traits were evaluated. Data were analyzed using the gene...

In this paper, we investigate a single server batch arrival non-Markovian retrial queueing model with random break down and Bernoulli vacation. Customers arrive in batches accordingly Poisson process with arrival rate λ but are served one by one with first come first served basis. All customers demand the first essential service, whereas only some of them demand the second optional service. The...

We consider a discrete-time Geo/G/1 retrial queue with starting failures in which all the arriving customers require a first essential service while only some of them ask for a second optional service. We study the Markov chain underlying the considered queueing system and its ergodicity condition. Explicit formulae for the stationary distribution and some performance measures of the system in ...

This paper analyses the steady state behaviour of an M/G/1 retrial queue with impatient subscribers, two phases of essential service, general retrial time and general vacation time. If the primary call, on arrival finds the server busy, becomes impatient and leaves the system with probability (1 ) and with probability , it enters into an orbit. The server provides preliminary first essential se...

The efficacy of a laboratory electrocoagulation (EC) system for treating egg processing plant wastewater (WW) is reported. For simulated and industrial egg processingWW, chemical oxygen demand, turbidity, and total suspended solids (TSS) were reduced 92 to 97%, 97%, and 99%, respectively, after treatment with EC. The final TSS concentration and turbidity values were 30 mg/ L and 5 formazin turb...

In order to accurately predict the Web service Qos in a highly dynamic environment,we put forward a Qos dynamic prediction method based on Semi-Markov Processes(SMP) and Case-based Reasoning(CBR).This method firstly uses semi-Markov process to predict business state of web service in the future, and then applies the technology of CBR to predict Web service QoS, for example,when the service deal...

A major merit of the Web Service Modeling Ontology WSMO is the wellstructured and unambiguous definition of the description elements for its components. This allows developing concise, generic inference mechanisms for basic Semantic Web Service technologies like Web Service Discovery as the detection of suitable Wed Services for solving a Goal. This paper introduces WOOGLE, a basic but powerful...

In classical circuit switching networks Quality of Service is an essential aspect which in uence the entire network design process, including routing consideration. Due to the e orts to introduce Quality of Service (QoS) into IP-based networks, design routing to support QoS becomes increasingly important, e.g. in such concepts like integrated service and di erentiated service IP networks. In th...

Cloud computing brings advancement in the field of information technology. Cloud computing is based on several service models such as SaaS, PaaS, NaaS, DbaaS, IaaS and many more. In order to make clear the essential of cloud computing, we propose the characteristics of these service models which distinguish cloud computing from other research areas .These service models are compared from variou...

Due to their heterogeneous nature, which stems from the definition of several XML-based standards to overcome platform and language dependence, Web Services have become an emerging and promising technology to design and build complex inter-enterprise business applications out of single Web-based software components. To establish the existence of a global component market in order to enforce ext...
