Middleware Design Framework for Mobile Computing

Abstract. Mobile computing is one of the recent growing fields in the area of wireless networking. The recent standardization efforts accomplished in Web services, with their XML-based formats for registration/discovery, service description, and service access, respectively UDDI, WSDL, and SOAP, certainly represent an interesting first step towards open service composition, which MA supports for mobile computing are expected to integrate within their frameworks soon. A middle-ware that can work even if the network parameters are changed can be a better solution for successful mobile computing. A middle-ware is proposed for handling the entire existing problem in distributed environment. Middleware is about integration and interoperability of applications and services running on heterogeneous computing and communication devices. The services it provides -including identification, authentication, authorization, soft-switching, certification and security -are used in a vast range of global appliances and systems, from smart cards and wireless devices to mobile services and e-Commerce

PCA BASED CLASSIFICATION OF SINGLE-LAYERED CLOUD TYPES

The paper presents an automatic classification system, which discriminates the different types of single-layered clouds using Principal Component Analysis (PCA) with enhanced accuracy as compared to other techniques. PCA is an image classification technique, which is typically used for face recognition. PCA can be used to identify the image features called principal components. A principal component is a peculiar feature of an image. The approach described in this paper uses this PCA capability for enhancing the accuracy of cloud image analysis. To demonstrate this enhancement, a software classifier system has been developed that incorporates PCA capability for better discrimination of cloud images. The system is first trained by cloud images. In training phase, system reads major principal features of the different cloud images to produce an image space. In testing phase, a new cloud image can be classified by comparing it with the specified image space using the PCA algorithm

Trade-off between automated and manual testing: A production possibility curve cost model

Testing is always important for Software Quality Assurance (SQA) activities and key cost multiplier in software development. The decision to automate or not to automate a test case is critical. In this paper we discuss the possibility of test automation and in relation to the trade-off between manual and automated test cases. We purpose a Production cost frontier based technique to distinguish the point of automation and manual test within the cost constraints. Our objective is to identify the facts that up to what extant a testing process can be automated. In this paper a cost model is proposed for deciding the proportion of automated and manual testing. The objective is to find best possible combination of these two and production possibility in one type by eliminating the other type of testin

A natural language processing approach to generate SBVR and OCL

The Object Constraint Language (OCL) is a declarative language and is used to make the Unified Modeling Language (UML) models well-defined through defining a set of constraints. However, the syntactic complexity of OCL makes the writing of OCL code difficult. A natural language based interface can be useful in making the process of writing OCL expressions easy and simple. However, the translation of natural language (NL) text to object constraint language (OCL) code is a challenging task on account of the informal nature of natural languages as various syntactic and semantic ambiguities make the process of NL translation to formal languages more complex. However, in our approach the usage of SBVR not only provides natural languages a formal abstract syntax representation but it is also close to OCL syntax. In this thesis, a framework is presented to facilitate the users of the UML tools so that they can write invariants and pre/post conditions in English. The results of the case studies manifest that a natural language based approach to generate OCL constraints can not only help in significantly improving usability of OCL but also outperforms the most closely related techniques in terms of effectiveness and effort required in generating OC
