in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...

Product innovation is a key achievement by which firm can not only build up its competitive advantages but also prolong survival in the open market environment. By understanding as social system pursuing both efficiency and effectiveness, this study examines three factors that independently enable product through theoretical lens of approach: strategic attention, external information sources, a...

A network is a graph where the nodes represent players and the links represent bilateral interaction between the players. A reward game assigns a value to every network on a fixed set of players. An allocation scheme specifies how to distribute the worth of every network among the players. This allocation scheme is link monotonic if extending the network does not decrease the payoff of any play...

The allocation of emissions allowances is among the most contentious elements of the design of cap-and-trade systems. In this paper we develop a detailed representation of the US western electricity market to assess the potential impacts of various allocation proposals. Several proposals involve the “updating” of permit allocation, where the allocation is tied to the ongoing output, or input us...

this paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. system engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (tco...

Economic models of land allocation may lead to expectations for farmer response that “surprisingly" do not materialize, if market prices fail to reflect the value of farmers' product. “Shadow prices" rather than market prices explain resource allocation better for farmers who attach significant non-market values to their own crops. I extend the theoretical model in Arslan and Taylor (2008) to e...

Manufacturing enterprises must face increasingly difficult production environments. External factors such as varying product variants and varying quantities as well as internal factors such as reworking and resource breakdowns pose a high challenge for task allocation and control. Inspired by the similarity between ant foraging behavior model and task allocation in manufacturing system, a phero...

In this paper, the power allocation strategy for the soft-decision-and-forward (SDF) protocol in the cooperative communication network with one source, one relay, and one destination, where each node has two transmit and receive antennas, is determined. For the slow-varying Rayleigh fading channel, the optimal power allocation ratio can be determined so as to minimize the average bit error rate...

Relatively few retailers include metrics such as product returns in their customer selection and optimal resource allocation algorithms when measuring and maximizing customer value. Even when they do include this metric, increases in product return behavior are usually considered merely an economic cost that needs to be managed by decreasing the marketing resource allocations toward the custome...
