Zakat is one of the Islamic pillars that has strategic contribution to the society. Zakat is one of the Muslim obligation. It is also a form of social solidarity. The collaborative research conducted by Badan Amil Zakat Nasional (BAZNas) and Institut Pertanian Bogor (IPB) estimated the potential of zakat collection in Indonesia could reach about Rp 217 trillion every year that has not been achieved yet. Researchers and practitioners have advised to implement a Knowledge Management System (KMS) to optimize the collection and BAZNas’s objectives. The objective of this research is to develop web-based Zakat Knowledge Management System (ZKMS). The KMS development methodology is done with using Knowledge Management System Life Cycle (KMSLC). Knowledge has been captured from experts consisting of practitioners and scientists from BAZNas of Bogor City, muzakki, documents, books and journals. ZKMS was developed using ASP.NET framework, C# programming language and MySQL database management system. The system has menu that are user, zakat knowledge, questions and answers with experts, interaction between members, about us, profiles and knowledge sources. This system is designed be user friendly to get, know, make, share, store and disseminate actual and contemporary of zakat knowledge.
天课是对社会具有战略性贡献的伊斯兰教支柱之一。天课是穆斯林的义务之一。它也是社会团结的一种形式。Badan Amil Zakat national (BAZNas)和Pertanian Bogor研究所(IPB)进行的合作研究估计，印尼每年收集天课的潜力可达到约217万亿卢比，但尚未实现。研究人员和从业人员建议实施知识管理系统(KMS)，以优化收集和bazna的目标。本研究的目的是开发基于网络的天课知识管理系统(ZKMS)。知识管理系统的开发方法是使用知识管理系统生命周期(KMSLC)来完成的。知识是从茂物市BAZNas的从业人员和科学家组成的专家、muzakki、文件、书籍和期刊中获取的。ZKMS采用ASP开发。. NET框架，c#编程语言和MySQL数据库管理系统。该系统的菜单包括用户、天课知识、与专家的问答、成员之间的互动、关于我们、个人资料和知识来源。本系统旨在方便用户获取、了解、制作、分享、存储和传播天课知识的现实性和时代性。

Protection of Medical image contents becomes the important issue in computer network security. Digital Watermarking has becomes a promising technique for medical content authentication, it allows to embed relevant information with the image, which provides confidentiality, integrity and authentication by embedding Digital Signature (DS) with the Medical image. In this paper we focus on need for reversible watermarking, Medical Image Compression and security related problems in medical images, it comparing the performances of various lossless watermarking techniques for various medical image modalities like MRI (Magnetic Resonance Imaging), US (Ultrasonic), CT (Computed Tomography), Endoscopic and Angiographic images. Region of Interest (ROI) supporting lossless watermarking systems only considered for discussions. Performance of all lossless watermarking with Digital Signature is analyzed by means of four parameters Capacity Rate, PSNR (Peak Signal to Noise ratio), NPCR (Number of Pixel Change Rate) and Compression Ratio (CR). This Paper also introduces new mechanism for open network security for medical images. This lossless watermarking is responsible for recovering the altered medical image content of the system.

To obtain the MEMS micro structure's high resolution measurement dynamic parameters ,this paper ,by obtaining stroboscopic imaging technology of micro structure of moving image sequence, proposed one kind based on the phase correlation technique and singular value decomposition technique combining sub-pixel measurement method. By the method of phase correlation, image space coordinate can transform into the frequency domain to the coordinates of the parameter space. And then through the singular value decomposition technique to obtain the correlation matrix, using the least-squares fitting, get the sub-pixel level displacement measurement results. The experimental results show that, with this method of measuring MEMS micro structure plane motion amplitude can reach sub-pixel accuracy, and can be effectively reduced by uneven illumination effect on the measuring result, thereby increasing the measurement results of stability and reduces the measuring error.
