Students’ Musculoskeletal Disorders Assessment Using RULA
Статья научная
Classroom and laboratory infrastructure, food quality, and the environment cause many health issues to the students at colleges and universities, like back pain, eye issues, shoulder pain, and pain in the spinal cord. These problems affect many students' physical and psychological capacity, and students lose enthusiasm and intelligence. This study was conducted at Mehran University of Engineering and Technology (MUET) to identify the ergonomic problems of students from attending lectures in class, performing different experiments in laboratories and workshops, and food quality at the canteens. This study focuses on ergonomic awareness and following rules and regulations for students and university administration. This research is conducted based on different questionnaires and the Rapid Upper Limb Assessment (RULA) method. Through questionnaires, we analyzed students’ physical and mental problems. The survey was conducted at the before mentioned university from a total of 104 random students. Using the RULA method, we take data from different postures of students while performing practical work in computer laboratories, mechanical workshops, and other laboratories. After analysis, it is found that the RULA score is almost 7, which is dangerous for health and further survey shows many health problems through questionnaires. It is suggested that universities should follow the ergonomics rules, make a good environment for classes, laboratories, and workshops also improve the food quality at the canteen to mitigate the health problems in students.

Study of Index Mechanism for GML Data
Статья научная
GML is the encoding specification of geospatial data, currently more and more geospatial data are represented in GML documents. In order to query GML data efficiently, appropriate index structure should be designed. As the application of XML in geospatial information field, the management of GML data can borrow ideas from the management technologies of XML data. Two types of existing XML path index technologies are analyzed, and a method to build path index for the GML document is proposed based on its storage schema. The path index records the sequences and levels of elements in the GML document. Tuples stored in tables can be quickly located for a query with the path index, and the structure information recorded in the path index can help to reconstruct the GML document.

Study on Algorithm of Digital Image Watermarking Based on DWT
Статья научная
In this article, watermarking algorithm is studied using digital watermarking technology based on the discrete wavelet (DWT) multi-resolution decomposition algorithm. Three-level wavelet decomposition is employed so that images are divided into three serial sub-graphs with high frequency band and one sub-graph with low frequency band. Since low-frequency information is more sensitive to human eyes than high-frequency information, watermarking is embedded into the high-frequency coefficients of the wavelet image. In our experiment, watermarking information is embedded into the original images by Matlab simulation. Besides, salt and pepper noise, Gaussian low-pass filter, amplifying 200% after narrowing 50% attack as well as JPEG coding are used to test the algorithm. Results show that our algorithm is robust and the visual effect is satisfactory.

Study on Data Fusion Algorithms of Landsat7 ETM+ PAN and Multi-spectral Imagery
Статья научная
Fusion of images with different spatial resolution can improve visualization of the images involved. This study tries to show that the fusion of the images from the same sensor system can improve quality of the original images. Four image fusion algorithms were used in the study of data fusion of Landsat 7 ETM+ imagery, taking southeastern part of Beijing City as the case study, they are the Smoothing Filter-Based Intensity Modulation (SFIM), High-Pass Filter (HPF) Transform, Brovey Transform, Multiplication (MLT) Transform. The effectiveness of the four fusion algorithms has been evaluated based on mean, deviation, information entropy, average gradient and correlation. The study reveals that the SFIM transform is the best method in retaining spectral information of original image, which does not cause spectral distortion and it has highest spatial frequency information. Therefore, fused images from the same sensor system can be used for improving visual interpretation and data quality.

Study on Quality control of CoPS Innovation Based on Quality Chain and Quality House
Статья научная
With the development of the science and technology, Complex Product and System (CoPS) plays a more important role in modern economy and society. This paper aims at the problem of quality control in the CoPS innovation. Through studying the CoPS characteristics and different innovation mode from the mass production, we established the quality chain model. The model is a process network in which nodes are consist of the suppliers, manufacturers and customers etc. the lines between the nodes is process of quality transmission. Compared with the process model of normal innovation, the process added four steps (task decomposition, analysis of knowledge demand, outsourcing selection and system integration) which reflect the Complexity of CoPS innovation. Traditional processes such as trial-manufacture and R&D process are involved in the module development. Despite that some scholars have a profound interest in the process of quality transfer in he quality chain and put forward some method solve quality problem of CoPS innovation, up to now little suitable and quantization method is presented. In the paper, quality houses are adopted to deal with the relation of quality chain nodes and interpret the process of quality transfer. Quality requests of one node are converted the technique indexes of another node in the quality house. At last an example is given to illustrate that this approach can improve quality control level more than the traditional statistical process control method and effectively reach quality management of CoPS innovation.

Research has shown that, after extensive use, digital devices like computers often suffer performance declines, and some even experience sudden, complete breakdowns without warning. This phenomenon is particularly disturbing for individuals who heavily rely on these devices to carry out critical tasks. Although researchers have extensively probed the causes of computer breakdowns, detailed parameters influencing the lifespan of computers remain underexplored. This paper, therefore, aims to estimate the probability associated with the continuous functioning or failure of a computer system over a specified duration, and to examine risk factors associated with failure. Delving into the mysteries of computer longevity, data on 100 computers in a designated lab at an academic environment were examined. Data was drawn from maintenance records as well as in-depth hardware assessments. Analysis revealed that, after a 4-year period of active usage, 73 of the computers remained operational, while 27 had malfunctioned. Survival analysis methods were employed to determine the probability of computers failing at specific points in time and to identify various factors contributing to early computer failure. The findings disclosed that at the two-year mark, the probability of computers remaining operational is 80%, decreasing to 62% at the three-year juncture. The median survival time was established at 3 years and 4 months. Furthermore, an analysis of causative factors revealed that computers with faulty motherboards and power supply units associates with a lower rate of survival, while computers with issues of hard drives, operating systems, and miscellaneous components has a higher rate of survival. This study provides comprehensive data-driven evidence that offers insights on the need to implement maintenance strategies to proactively extend the lifespan of computers.

TakeXIR:a Type-Ahead Keyword Search Xml Information Retrieval System
Статья научная
As XML (eXtensible Markup Language) is becoming a standard widely applied in data representation and data exchange in web service. In this paper, we propose a novel approach to type-ahead keyword search in XML data, call TakeXIR. The IR-style approach basically utilizes the statistics of underlying XML data to address the following challenges in XML IR system: (1) Identify the user search intention, i.e. identify the keywords to express user interests and identify nodes user wants to search for and search via. (2) Resolve keyword ambiguity problems: synonyms and polysemy exist in natural language, and a keyword can appear as the text values or tag value of different XML node and carry different meanings.
