Inter-App Communication (IAC) plays an important role in Android platform to share data and services among applications. However, the existence of IAC capability leaks could lead to the unauthorized privileged operations. In this paper, we first investigate the usage of IAC in Android applications to show the prevalence of IAC in the Android development model. To mitigate the threat caused by IAC...
Over the past decade, development of computer-aided graphics in the field of appliedgraphics is rapid, and the graphics system which is established based on the traditional ruler gauge conditions has also changed dramatically. Therefore, the author reviewed the current situation, following the pulse of the information times, on the premise of practice and application, making bold adjustment to the...
We have developed a wireless system suitable for acquiring gastric slow wave activities and delivering electrical pulses to the stomach. The system is composed of a physically miniaturized front-end that can record slow waves from 3 channels and transmit the data to a back-end connected to a computer. A custom-made graphical user interface can display the slow waves in real-time and store them for...
Caching is an important technique to improve computer system performance by storing the most recently used data and instructions for main memory. Cache is widely used in modern computer systems and will continue to be an irreplaceable unit to narrow the speed gap between processor and main memory. With the increasing capacity of main memory and the number of processor cores, the cache technology has...
Power efficiency has been recognized as an important factor of the computing technology. On-chip caches represent a sizable faction of the total power consumption of microprocessors. Non-uniform cache access (NUCA) cache split the cache into several tiles, which enables the ability to power down some tiles at run time. We observed that some workloads have related small working set, thus we can dynamic...
Effective and efficient test-sheet composition algorithm is the key to computer-aided testing. Based on harmony search algorithm, a novel binary intelligent algorithm for the test-sheet construction was studied. Using different scale item banks, simulation experiments were conducted to assess the performance of the proposed algorithm and the results were compared with the Simple Genetic Algorithm...
The computer experiment teaching is an important link in the chain of the teaching of the courses related to computer and many other correlative professional courses, whose quality affects on the whole teaching results. How to evaluation it involves many factors, which are integrated and fuzzy. An evaluating indicator system, which fits for the character of the computer experiment teaching, was set...
This paper proposes a new idea for the educational reform of computer network curriculum in the finance and economics colleges, which can be performed relying on the predominance and unique features of the finance and economics colleges. The orientation of the computer network curriculum is for economic system, based on this, the corresponding course system is proposed, the characteristic teaching...
Virtualization Technology has been employed increasingly widely in modern data centers in order to improve its energy efficiency. In particular, the capability of virtual machine(VM) migration brings multiple benefits for such as resources(CPU, memory, et al.) distribution, energy aware consolidation. However, the migration of virtual machines itself brings extra power consumption. For this reason,...
The test method oriented function call path acquires function call paths through static analysis, but the uncertainty between definitions and call forms of function template in static analysis produces many redundant paths, which makes test workload increase exponentially, so determining uniqueness of function template call relation is an important part of improving test efficiency. Through analyzing...
A novel hole filling simplification algorithm based on feature-enhancing is proposed to improve the missing features reparation. First, the constraint points area of radial basis function is estimated to confirm the filling surface of hole area. And then, the hole surface is sampled and delaunayed according to the topological structure of the neighboring points. At last, the reparation features are...
As a requisite of the digital image process, fuzzy object extraction is of great importance. In this paper, a novel region growing method based on fuzzy connectedness is proposed. Firstly, fuzzy connectedness is taken as similarity measure between the seed pixel and current pixel and guides the region-growing process. Then, a combined stop criterion integrating adaptive threshold and usan area is...
