We study the breaking of supersymmetry and its transmission to the light states in the context of the minimal SU(5) grand unified theory, with no additional singlets. This simple theory can be taken as a prototype for a program of breaking simultaneously grand unified symmetry and supersymmetry. The main predictions are: (i) d=6 proton decay is completely negligible and d=5 is in accord with ex...

We discuss a multi-objective/goal programming model for the allocation of inventory of graphical advertisements. The model considers two types of campaigns: guaranteed delivery (GD), which are sold months in advance, and non-guaranteed delivery (NGD), which are sold using real-time auctions. We investigate various advertiser and publisher objectives such as (a) revenue from the sale of impressi...

The increasing availability of individual-level data has raised the standards for measurability and accountability in digital advertising. Using a massive individual-level data set, our paper captures the effectiveness of display advertising across a wide range of consumer behaviors. Two unique features of our data set that distinguish this paper from prior work are: (i) the information on the ...

The emphasis on code re-usability in component-based software development has resulted in degradation of system performance. Component specialization techniques have been proposed to overcome this problem. They mainly specialize components wrt contents of component interfaces. This requires specialization to be performed in either a forward or backward direction. The current state of the art ap...

With the rapid increase of online advertisements in marketing, as well as the user's attention resources are becoming scarce, targeting technique is applied to improve the efficiency and effectiveness of online advertising by delivering the right advertisement to the right audience, at the right time and situation, and with the right method. The attention of current targeting is transformed fro...

Interactive advertising which characterized by interactivity has become the mainstream of advertising by gradually replacing traditional one-way advertising during the new media era. This paper has obeyed the research outline below, literature review, background description, assumption proposed, and empirical analysis. Therefore, this paper proposed the communication model of interactive advert...

The use of simple auction mechanisms like the GSP in online advertising can lead to significant loss of efficiency and revenue when advertisers have rich preferences—even simple forms of expressiveness like budget constraints can lead to suboptimal outcomes. While the optimal allocation of inventory can provide greater efficiency and revenue, natural formulations of the underlying optimization ...

This study develops a data-driven approach to solve constrained optimization problems in which the decision maker does not have an analytic form for the objective function, but knows what decision variables affect the function. The approach makes direct use of the available data, rather than first using the data to estimate the objective function and then solving the problem as a traditional op...

Search Engine Advertising (SEA) is at the same time a prominent source of revenue for search engine companies, and also a new solution for businesses to promote their visibility on the Web. However, there is little research about what factors and the extent to which these factors may contribute to businesses’ decision to adopt SEA. Building upon Theory of Planned Behaviour, Technology Acceptanc...
