Management scientists state that for the purpose of surviving and developing, it is necessary to be engaged in learning forever. Learning can help' organizations with any changes, innovations, and creations. According to studies, the learning capacity in nationwide administrative organizations is rather low. In this article, first the concept and also the necessary characteristics for learning ...

Information and communication technology (ICT) tools are known to facilitate communication and processing of information and sharing of knowledge by electronic means. In Nigeria, the lack of adequate capacity on the use of ICT by health sector policymakers constitutes a major impediment to the uptake of research evidence into the policymaking process. The objective of this study was to improve ...

this study aimed at identifying and analyzing issues and challenges on the agricultural research and technology development under the national innovation framework. the survey consisted of two groups: agricultural researchers of agriculture-research and education organization and all faculty members of public agricultural faculties of ministry of scientific, research and technology. using cochr...

Systems that employ multiple antennas in both the transmitter and the receiver of a wireless system have been shown to promise extraordinary spectral efficiency. With full channel knowledge at the transmitter and receiver, Raleigh and Cioffi proposed a spatio-temporal coding scheme, discrete matrix multitone (DMMT), to achieve asymptotically optimum multiple-input–multiple-output (MIMO) channel...

Time division duplex systems, in a convenient way, facilitate the implementation of asymmetrical links which are required to efficiently handle the increasingly asymmetric traffic offered by current and future wireless applications. If boundaries between uplink and downlink time-slots are not synchronised among cells, e.g. when different asymmetries are required in different cells, Inter-Base s...

Dynamic Channel Allocation (DCA) has been seen as a promising method for improving quality and capacity in cellular networks. In theoretical studies very significant quality and capacity improvements has been achieved. However, in real systems DCA performance is limited by several factors so theoretical limits might not be reached. To exploit full possibilities of TDD system efficient DCA algor...

For a partially degradable (PD) channel, the channel output state can be used to simulate the degraded environment state. The quantum capacity of a PD channel has been proven to be additive. Here, we show that the private classical capacity of arbitrary dimensional PD channels is equal to the quantum capacity of the channel and also single-letterizes. We prove that higher rates of private class...
