...Personalized Optimization for Android Smartphones WOOK SONG, YESEONG KIM, HAKBONG KIM, JEHUN LIM, and JIHONG KIM, Seoul National University As a highly personalized computing device, smartphones present a unique new opportunity for system optimization. For example, it is widely observed that a smartphone user exhibits very regular application usage patterns (although different users are quite different in their usage patterns). User-speciﬁc high-level app usage information, when properly managed, can provide valuable hints for optimizing various system design requirements. In this article, we describe the design and implementation of a personalized optimization framework for the Android platform that takes advantage of user’s application usage patterns in optimizing the performance of the Android platform. Our optimization framework consists of two main components, the application usage modeling module and the usage model-based optimization module. We have developed two novel application usage models that correctly capture typical smartphone user’s application usage patterns. Based on the application usage models, we have implemented an app-launching experience optimization technique which tries to minimize user-perceived delays, extra energy consumption, and state loss when a user launches apps. Our experimental results on the Nexus S Android reference phones show that our proposed optimization technique can avoid unnecessary application restarts by up to 78.4% over the......

... Search Engine Optimization Name Institution Affiliation Course Tutor Date Search Engine Optimization The World Wide Web has in the modern world become so vital in the sharing and connection of files and documents on the internet (Johnson, 2014). Because of the millions of files and documents available on the World Wide Web, programs have been developed to help users in their search for documents on the internet (Rohan, 2014). A program that locates and identifies documents on the World Wide Web that match keywords specified by the user is called a search engine. Popular examples of search engines include Google, Yahoo!, and MSN Search. After conducting a search, the engine displays websites that contain documents marching the keywords typed by the user with the most relevant at the top. The websites that appear at the top do so because of a technique known as search engine optimization (SEO). This technique assists search engines to identify and rank higher particular websites than numerous others in response to a search query. SEO involves writing pages that use keywords that are in regular use by people in searches (Rohan, 2014). Website owners use SEO in order to acquire quality results within search engines that are frequented by users, and this is in a bid to increase traffic to their websites. Designing and optimizing a site in a manner that it attains the highest search rankings is what SEO entails. The use of SEO is the cheapest as......

...The value of Abis optimization PUBLIC 2011-11-10 Issue 39 of Huawei Communicate Page 1 of 6 Not So Worthy: Abis optimization With the rapid development of mobile services, there had been increasing pressure and demands on mobile backhaul bandwidth, especially in terms of 3G service provision. Abis optimization can ameliorate this situation to some extent by enhancing transport efficiency, but the total value it generates remains in question. Theory of Abis optimization As 3G traffic continues to grow, operators must tackle the issue of higher bandwidth requirements. This has resulted in huge investments for network capacity expansion. With such high demands for bandwidth optimization, various technologies have been developed and applied to mobile backhaul networks—Abis is one of the many options available. Voice services remain a dominant commercial interest for mobile operators. Since GSM system differs from 3G UMTS systems in terms of voice service processing, Abis optimization technology has various effects. GSM system utilizes full-rate (FR) codes to process voice services, and occupies transmission bandwidth even during the mute period of the communication process. Abis optimization technology is designed to eliminate mute frames through its BTS interface. It can also multiply the unused timeslots. The mute frames are then recovered before the BSC, enhancing 2G service transport efficiency by an average of 60%, and even 80% in best case scenarios. On...

...Mathematical Optimization: Models, Methods and Applications Final Assignment 06-11-2015 Rasmus pages / 13.137 characters (including spaces) | Part 1 General about part 1 The purpose with this part is to analyze a Single-Sourcing Problem (SSP). A Single-Sourcing Problem of course both has benefits and risks, but I will discuss that furthermore through the assignment. During the assignment I will try to discuss and comment on everything that I do. My code and the answers I receive from www.neos-server.org can be seen in my appendices. (i) In the first question in part 1, I am asked to solve the SSP using the data in Figure 1. We have 4 facilities and 30 customers. In Figure 1 the demand of each customer is also given, and of course I will have to satisfy this. Therefore this will become one of my constraints. It is also known that each facility has a capacity, and of course this will become a constraint as well. Because it is a SSP problem, we are also given the information that each customer has to be served by exactly one facility. When a facility delivers one unit to a customer it faces a cost. The purpose with the first question is to minimize the cost that the facility faces delivering the units. I will now show what the problem looks like: Minimizexi=1mj=1nai,j dj xi,j subject to j=1ndj xi,j≤ci , i=1,…,m i=1m xi,j=1 , j=1,…,n x∈0,1, i=1,…,m , j=1,…, n Now I have formulated the problem, and I will now use a Mixed Integer Linear Programming solver...

...Sub Optimization Definition: “The result of different departments each attempting to reach a solution that is optimum for that department” (Stevenson, 2015). Unfortunately, the sub-optimization process does not always adhere to the principle “the whole is more important than the sum of its parts”. Sub optimization occurs when different departments each attempt to reach a solution that is optimal for that department, but that may not be optimum for the organization as a whole. This type of policy can actually do more harm than good. When one department is delivering faster than another department can handle this could cause what is known as a “bottleneck” in the process, which may result in lost profits and customers. “This is a typical effect of sub-optimization. If you only optimize one step in your value creation process it can deliver things faster than the rest of the organization can deal with. Either that part runs dry on input or the output of that part floods subsequent process steps. Make sure that no one department produces more than the department with the least capacity (the bottleneck) can handle” (Marschall, 2011). In the management book “The Goal, Eliyahu Goldratt gives the example of a decision to make machining centers in a factory more efficient by increasing the amount of metal taken off with each pass of the cutting tool. However, Increasing the amount of metal taken off on each pass made the parts brittle, which necessitated heat-treating. The...
