Evaluation of the state of the Business Intelligence among small Czech farms.

Business Intelligence (BI) can assist in agricultural enterprises to strengthen their production potential and tech- nical effi ciency due to its eff ective support to the managerial, analytical, planning, and decision-making activities of man- agers and specialists. However, the state of the BI in the Czech Republic is not still completely understood. In this context, this paper aims at the evaluation of the current state of the art of the BI among small Czech farms. Th e focus of the re search was put on the evaluation of both the state of the BI, and the relevant business information systems and software for agri- culture. Th ere was a survey among 135 agricultural entrepreneurs from various regions in the Czech Republic. Th e survey results are presented by the descriptive statistics and frequency tables. Th ere is an examination of the relationship between the agricultural enterprise structure and the use of the BI. Dependencies among the examined characteristics were sought by the means of the analysis of qualitative variables. With 95% probability, it could be claimed that the type of production, the size of farmed land, the number of employees and the level of fi nancial subsidies have no signifi cant impact on using the BI, the expert and analytical systems in agricultural enterprises.

Measurement and Analysis of Quality of Service of Mobile Networks in Afghanistan – End User Perspective

Enhanced Quality of Service (QoS) and satisfaction of mobile phone user are major concerns of a service provider. In order to manage network efficiently and to provide enhanced end – to – end Quality of Experience (QoE), operator is expected to measure and analyze QoS from various perspectives and at different relevant points of network. The scope of this paper is measurement and statistically analysis of QoS of mobile networks from end user perspective in Afghanistan. The study is based on primary data collected on random basis from 1,515 mobile phone users of five cellular operators. The paper furthermore proposes adequate technical solutions to mobile operators in order to address existing challenges in the area of QoS and to remain competitive in the market. Based on the result of processed data, considering geographical locations, population and telecom regulations of the government, authors recommend deployment of small cells (SCs), increasing number of regular performance tests, optimal placement of base stations, increasing number of carriers, and high order sectorization as proposed technical solutions.
