Summary:
In this paper, the researcher studied about the one-sender-multiple receiver transmission technique. It allows a sender to send multiple receivers on the same frequency simultaneously by utilizing multiple antennas at the sender. For the researchers, the OSMR has the potential to significantly improve the downlink performance of wireless LANs, because of this; they can send distinct packets to multiple computers at the same time. They studied this research in Florida State University and done lots of experiments. Since this research topic is technical, they gathered data in done lots of statistical solutions. They focused on the problem maximizing network throughout and did propose a simple algorithm. The algorithm is simple and did suitable for the implementation with inexpensive processors.
Evaluation:
The abstract of the study is only one paragraph and with few words only but it directs to the point of what the study is all about. Since that the study is more on very technicality, and the statistics formulas is very broad to understand, it was defined very well. They had a graphical solution, formulas, and experiments. Though they never mentioned it, I mean the methodology they used.
The whole paper was kind of confusing stuff for me. Like what I said during my sharing time, research paper don’t have specific format, but on this paper, what I have discussed is not really the same. What I noticed is that every experimentation they done, they put it in another title. Then, at the final part was their conclusion. The conclusion is somehow similar to the abstract. Since they were really at it to solve or to create solutions which are stated in the abstract.

Summary:
Predictux, is a decision tree based framework for predicting how many days the next Linux kernel version will take to be released, based on analyzing some parameters of its past releases. In other words, this study focuses on the prediction of Linux date time to be next released. The word is released is being used to mean a subset of a software system’s functionality that is released to users for testing, use, and feedback. The research they have conducted is to examine the time a Linux kernel is to be released and within that time is there a chance that the software is reliable. With this, they did gather lots of factors to determine the time. Since that it determining the time, it requires lots of factors then. They used the decision tree to ease the understanding and interpreting the time. They did experimental validation as well as open issues and future works.
Evaluation:
The abstract was just a glimpse of what the study is all about. The problem was being discussed in the introduction and motivation. There were only 5 chapters being discussed in this topic: The introduction, the framework, the validation of experiments, the open issues and future works, and the conclusion. What they discussed is just a brief summary of what they conducted. Actually, it is simple compare to the first research topic I have listed. And it is easier to understand though they still use statistics on it. The topic was really understandable. And on their conclusion, they conclude the answer to their problem. Though at first it was just hypnosis, at the end, after experimentation and statistical methods they done, they come up to a certain answer.

Summary:
In this paper, it introduced and illustrates the use of the project entropy metric to understand the dynamics of allocating resources across software projects. They also forwarded a hypothesis regarding the limit to which resource reallocation to enhance user satisfaction and outlined plans for further empirical validation of their ideas. In this research, the project entropy is a formula to testify the percentage of the user to accept particular software after its release. They still have hypnosis and hypothesis in gathering and formulating solutions. Meaning, they undergo simulation.
Evaluation:
It still has the same kind of paper on the previous research paper. Since that they have the same researcher. Like above, it provides the certain solution or answer based on their experimentation and simulation. Then the chapters included in this research also has 5 chapters.
