An information hiding algorithm is proposed, which hides information by embedding secret data into the palette of bitmap resources of portable executable (PE) files. This algorithm has higher security than some traditional ones because of integrating secret data and bitmap resources together. Through analyzing the principle of bitmap resources parsing in an operating system and the layer of resource data in PE files, a safe and useful solution is presented to solve two problems that bitmap resources are incorrectly analyzed and other resources data are confused in the process of data embedding. The feasibility and effectiveness of the proposed algorithm are confirmed through computer experiments. 展开更多

The basic assumption of an energy-efficient project is the proper relation with the local climatic context.To analyse a building’s performance before its construction,it is necessary that the object to be designed is recreated in a virtual environment,to evaluate its thermal balance.In order to recreate this virtual environment,it is necessary to use computer programs,and that requires a file composed of a weather database organized hourly in a specific year and defined,in the case of this article,from a TRY(test reference year).The objective of this study is to prepare a weather file for the city of Pelotas,RS,Brazil.This research was structured in five stages.In the first stage,the TRY was determined.In the second stage,the necessary variables for the preparation of the weather file to be used in the programs EnergyPlus?and Design Builder?were created and treated.In the third stage,weather files were prepared in.epw and.try formats.In the fourth stage,the weather file generated was simulated and compared with two other weather files belonging to the same bioclimatic zone.In the fifth and last stage,a typical day was elaborated for the city of Pelotas.As a result,the importance of optimization of the EPW generation process based on algorithms was highlighted.It was also verified that although we have three nearby cities with similar characteristics,it is possible to have differences of simulation results when the appropriate weather file is not used. 展开更多

Extracellular manganese peroxidases (MnPs) produced by native and mutant strains of Trametes versicolor IBL‐04 (EB‐60, EMS‐90) were purified by ammonium sulphate precipitation and dialysis, followed by ion‐exchange and gel‐permeation chromatography. The purified enzymes elucidated a single band in the 43‐kDa region on sodium dodecyl sulphate‐polyacrylamide gel electrophoresis. The optimum pH and temperature of the purified enzymes were found to be 5.0 and 40 °C, respec‐tively. Mutant strain MnPs exhibited a broader active pH range and higher thermal stability than native MnP. Purified MnPs from selected mutants showed almost identical properties to native MnP in electrophoresis, steady‐state kinetics, and metal ion and endocrine‐disrupting compound (EDC) degradation efficiency. Although the fastest reaction rates occurred with Mn2+, MnPs displayed the highest affinity for ABTS, methoxyhydroquinone, 4‐aminophenol and reactive dyes. MnP activity was significantly enhanced by Mn2+and Cu2+, and inhibited in the presence of Zn2+, Fe2+, ethylene‐diaminetetraacetic acid and cysteine to various extents, with Hg2+ as the most potent inhibitory agent. MnPs from all sources efficiently catalyzed the degradation of the EDCs, nonylphenol and triclosan, removing over 80%after 3 h of treatment, which was further increased up to 90%in the presence of MnP‐mediator system. The properties of T. versicolor MnPs, such as high pH and ther‐mal stability, as well as unique Michaelis‐Menten kinetic parameters and high EDC elimination effi‐ciency, render them promising candidates for industrial exploitation. 展开更多

We study the large-time behavior toward viscous shock waves to the Cauchy problem of the one-dimensional compressible isentropic Navier-Stokes equations with density- dependent viscosity. The nonlinear stability of the viscous shock waves is shown for certain class of large initial perturbation with integral zero which can allow the initial density to have large oscillation. Our analysis relies upon the technique developed by Kanel~ and the continuation argument. 展开更多

The aim of this paper is to analyze the sharing and management of files in a tertiary institution using blockchain architecture. It is expected to enable an online system that could provide a decentralized architecture for multiple transfers and sharing of files amongst participants, to design a system that can provide data integrity and security of files using IBM Blockchain technology, to provide a system that can allow multiple user and multiple transactions at once. The research was motivated because of the security challenges associated with existing system which include: delay in transfer and sharing of files, much authority and task given to a single user in a centralized system, high risk of attack and loss of files, reduced speed of file transfer and file access/retrieval, limited number of users per time. Methodology adopted was Object Oriented Analysis Design Methodology (OOADM) in conjunction with Unified Modeling Language (UML) and IBM Blockchain Technology while the programming language used was HTML, CSS, Java and Node Js. The result after design was a decentralized cloud based file sharing and management system that enables multi-shared, replicated and permissioned transactions amongst participants in a network. 展开更多

In public health emergencies, the collection of archival information in the area of public health emergencies is very important, which can provide a reference for the early warning and processing mechanism. At the present stage, the unlimited demand of archival users for resources and the convenience of obtaining resources have become the two driving forces to promote the “transformation” and “growth” of archives. Public health emergencies, the transformation of archives collection and service mode, social media has become an indispensable platform for user information exchange, sharing and transmission, which requires archives to change the mode of archives acquisition and storage. Archival users require more interactive, targeted and cutting-edge forms of access and archival services are also developing toward diversified functions and connotations. Archival information resource sharing is also an important link in this development trend. This paper attempts to analyze the collection methods of archives departments in public health emergencies, and then puts forward the corresponding measures for archives departments to play their functions, such as flexibly solving the needs of archives access, strengthening the development of information resources, doing a good job in the collection of relevant archives, and publicizing archives work in combination with hot spots. This paper discusses the completeness of archival data collection, the means of archival management, the scientific classification of archival data, the ways of archival data collection and so on. 展开更多

Aim: the aim of this study was to investigate the shaping ability of thermomechanically treated files manufactured by twisting(Twisted files)and compare it to conventional rotary system (K3, Sybron Endo, Orange, CA) in S-shaped canals, including formation of ledges, zipping, elbow, outer widening, danger zone, perforation and file deformation. Materials & Methods: Forty S-Shaped canals in resin blocks were randomly divided into 2 groups of 20 each. Pre-instrumentation images of the canals were taken via a digital camera and superimposed on images taken after preparation with TF and K3 systems to apical size of 25/06 and 30/06. Canal aberrations were measured from the superimposed image at five levels using AutoCAD system. Fisher exact test and Mann Whitney test were used for analysis of the data. Results: the incidence of zipping, elbow and apical transportation was significantly lower in the TF group (P = 0.04). Generally the incidence of aberration increased when the apical size increased to 30/0.06 regardless of the file system. Significant file deformation was evident in the TF after single use (P ? 0.001). Conclusion: Under the conditions of this study, TF manufactured by new technique performed better than K3 systems when used up to size 25/06 in simulated S-shaped canals. Clinical significance: The flexibility of thermomechanically treated files is beneficial in canals with multiple curvatures;however, attention should be paid to the instrument taper and final apical size of the preparation. 展开更多

The feasibility of estimating patient-specific dose verification results directly from linear accelerator (linac) log files has been investigated for prostate cancer patients who undergo volumetric modulated arc therapy (VMAT). Twenty-six patients who underwent VMAT in our facility were consecutively selected. VMAT plans were created using Monaco treatment planning system and were transferred to an Elekta linac. During the beam delivery, dynamic machine parameters such as positions of the multi-leaf collimator and the gantry were recorded in the log files;subsequently, root mean square (rms) values of control errors, speeds and accelerations of the above machine parameters were calculated for each delivery. Dose verification was performed for all the plans using a cylindrical phantom with diodes placed in a spiral array. The gamma index pass rates were evaluated under 3%/3 mm and 2%/2 mm criteria with a dose threshold of 10%. Subsequently, the correlation coefficients between the gamma index pass rates and each of the above rms values were calculated. Under the 2%/2 mm criteria, significant negative correlations were found between the gamma index pass rates and the rms gantry angle errors (r = 0.64, p < 0.001) as well as the pass rates and the rms gantry accelerations (r = 0.68, p < 0.001). On the other hand, the rms values of the other dynamic machine parameters did not significantly correlate with the gamma index pass rates. We suggest that the VMAT quality assurance (QA) results can be directly estimated from the log file thereby providing potential to simplify patient-specific prostate VMAT QA procedure. 展开更多
