A Universal Malicious Documents Static Detection Framework Based on Feature Generalization

In this study, Portable Document Format (PDF), Word, Excel, Rich Test format (RTF) and image documents are taken as the research objects to study a static and fast method by which to detect malicious documents. Malicious PDF and Word document features are abstracted and extended, which can be used to detect other types of documents. A universal static detection framework for malicious documents based on feature generalization is then proposed. The generalized features include specification check errors, the structure path, code keywords, and the number of objects. The proposed method is verified on two datasets, and is compared with Kaspersky, NOD32, and McAfee antivirus software. The experimental results demonstrate that the proposed method achieves good performance in terms of the detection accuracy, runtime, and scalability. The average F1-score of all types of documents is found to be 0.99, and the average detection time of a document is 0.5926 s, which is at the same level as the compared antivirus software.

Practical Thinking on Landscape Renovation Design of the Riverbed and its Surrounding Areas of the Jiang River in Shiyan City

Based on the concept of common life between man and nature, the paper aims to guide people to deeply feel the nature. It combs and analyzes the landscape cases of the Jiang River by means of literature research and observation to achieve the transformation and upgrading of the stereotyped river landscape into the organic combination of art and nature. In the study, it is found that to achieve the ideal landscape effect, the transformation should be based on the concept of returning to nature, and the natural landscape conditions of the research objects should be combined to strengthen or weaken the characteristics of the base.

Pemanfaatan citra kamera inframerah thermal (kit) untuk mendeteksi area inflamasi pada tubuh manusia

Inflammation is an indication of an abnormality in the human body. Cases of inflammation occur accompanied by changes in temperature on the surface of the body. The location and location of the spread of inflammation cannot be seen solely by the human eye in detail. An imaging modality tool that is suitable for use in observing this problem is needed. In this study, the Thermal Infrared Camera (TIC) is used as an imaging modality. Samples in the form of a pair of legs in which one part of inflammation occurs are used as research objects. TIC is an imaging modality tool that can detect temperatures on the surface of an object quickly and is nondestructive. The results of the TIC image are processed using the global thresholding image processing method to distinguish between the inflammatory areas and normal areas more specifically. The results displayed indicate that there are differences in the image between the area of inflammation with the normal area of the patient's feet. The results of image processing data in the form of binary images show between the inflammatory area represented by white and vice versa the normal area represented by black. A comparison between the two conditions of the patient's feet before and after recovery shows the shrinkage of the area. There are two main results obtained in the exploration of this research, which is successful in distinguishing the inflammatory area from the normal area and the progress of recovery from the legs of the affected patient.

Improving the Efficiency of Managing the Development of the West Siberian Oil and Gas Province Fields on the Basis of Differentiation and Grouping

—Using image recognition methods (principal component method (PCM) and discriminant analysis) made it possible to group and identify more than 500 research objects developed in five oil and gas areas of the West Siberian oil and gas province (WSOGP), which are confined to 13 large tectonic structures and 10 productive horizons. The grouping was made according to 19 parameters characterizing the mode of oil and gas occurrence and the geologic–physical and physicochemical properties of the reservoirs and hosted fluids exerting a prevailing influence on the recovery of oil reserves and used on projecting the development of research objects. The performed study has identified 19 relatively homogeneous groups of objects, each having a specific set of geologic–physical properties. It is shown that the parameters reflecting the geologic–physical and physicochemical properties of the reservoirs and fluids within the identified groups of objects exert different effects on the recovery of oil reserves. This requires differentiation and grouping of the objects during the solution of various development problems. It has been established that the specific features of groups of objects are determined primarily by areal, tectonic, and stratigraphic factors and that grouping must be performed separately in each stratigraphic system. Algorithms are proposed for grouping the developed oil and gas fields and for searching for groups of analogous objects in fields out of exploration that are most similar to the developed ones. The performed grouping and the results obtained provide the necessary information about the research objects and increase its reliability, thus making it possible to improve the efficiency of managing the oil company assets, i.e., the WSOGP oil fields.

Influence of movement tracks on the forming quality of profiles fabricated by flexible stretch bending of multi-point roller dies technology

In the flexible stretch bending of multi-point roller dies process, the deformation of workpiece is mainly driven by clamps. Therefore, the movement track of clamp has a great influence on the forming effect of workpiece. Y-profile, T-profile, and L-profile are taken as the research objects. Simulation and experiments are carried out with two different movement tracks. The influence of the movement tracks on shape error, springback error, and thickness variation of different profiles is discussed. The experimental results of the three profiles processed by the double-sided forming method are consistent with the simulation results, which proves the accuracy of the numerical simulation. The results show that the movement track has a great influence on shape error. Compared with double-sided forming, one-sided forming can effectively reduce springback error. The two different movement tracks have no obvious influence on thickness change.
