With the advent of the globalization paradigm, the industrial interactions among manufacturing companies have become easier, and the possibility of sharing of the resources among them has been introduced. This issue, coupled with the increasing diversity of customer needs, has led to a change in business models of manufacturing industries and because of that, in the field of globalized manufacturing, a new paradigm called cloud manufacturing has been proposed in which service-orientation is one of the main features. Despite of the extensive studies on cloud manufacturing, the lack of a framework that, based on the service-orientation, determines the improving of manufacturing processes to... 

Reusing third-party libraries is inevitable to reach an acceptable development time and cost in current application development methodologies. As these libraries are placed in the address space of the native application, they have the same access rights as it.These libraries may contain deliberate or unintended bugs that result in security vulnerabilities.Previous approaches to limit access rights of these libraries either lack a comprehensive control over different resources, e.g., they prevent unprivileged access to RAM while illegal disk or network access is still possible, or impose significant performance overhead.In this thesis, we have presented a secure approach to third-party... 

Hyperspectral unmixing (HU) is a method used to estimate the fractional abundances corresponding to endmembers in each of the mixed pixels in the hyperspectral remote sensing image. In recent times, deep learning has been recognized as an effective technique for hyperspectral image classification. In this thesis, an end-to-end HU method is proposed based on the convolutional neural network (CNN) and multi-layer perceptron (MLP). which consists of two steps: the first stage extracts features from the input data along with the inverse learning of the spectral library matrix in the hyperspectral image where columns represent the pure spectral of endmembers and The second stage is to estimate... 

PMBOK is a standard that is the subset of Project Management Knowledge and includes all areas. ITIL is a framework that allows IT organizations using best practices in IT Service Management. Both of them includes some process that during implementation and execution should act based on them. The goal of developing a methodology for implementing ITIL V3 based on PMBOK is executing a comparison mapping for connecting these two difference fields. IT managers know about ITIL implementation, but most of project managers are not familiar about it. If we guess that implementing ITIL V3 is a project, a project manager can do it based on PMBOK. With mapping these two fields, project managers are able... 

Today, with the development of information systems and the use of information technology in organizations and the act of IT department to become out of isolation mode and also alignment of IT with the strategies and goals of the business units, many believe that the information should flow in organization without any borders. In addition to having common points, each of these frameworks have different features that make organizations have difficulties in choosing between them. It should be noted that the implementation of two or more frameworks together, can waste time and money, cause lots of rework, and also can lead conflicting outcomes in their organizations. Enterprise architecture... 

Developing distributed systems is always harder than centralized systems, because in distributed systems there are problems like how nodes must collaborate with each other, throughput, latency and so on, that is not concerned in centralized systems. For solving this problem, It's better to have an abstract view of system to show this concerns. one of the coordination languages to have that abstract view of system, is Reo language. Reo language is a coordination language that describe how components of systems, can coordinate with each other. This project is built to decrease the distance between designing and implementing. In this project an abstract view of system which is in Reo language,... 

Developing an android application from scratch is a time-consuming and expensive process, but modifying an existing and similar application is much easier. Modifying an android application, which is called repackaging, is done for different purposes. Cracking non-free android applications, modifying advertising libraries code, adding malicious payload to benign ones and redistributing known malwares are some of the important purposes. Existing methods for confronting android application repackaging can be divided into three categories: 1) based on comparing with the original application, 2) based on changing the original application, 3) based on changing the android platform. Methods in the... 

The use of protons and charged particles such as carbon in the treatment of cancerous tumors is one of the new methods of external radiation therapy. Proton therapy can achieve almost the same tumor dose coverage as traditional photon therapy with a greatly reduced dose to the normal organ. The radiation deviations caused by the magnetic field are an effective factor in reducing the dose of vital organs without sacrificing the dose coverage of tumors; Therefore, a new method of proton therapy, called magnetic field-modulated proton therapy, has been proposed, in which the Bragg peak positions of proton beams can be modulated under the cover of predesigned magnetic fields inside cancer...
