Abstract:
In this paper, make a new layer model, call it as fusiformis-model. This model is a Web-based model, this new model is a traditional three-tier model refinement, and it is divided into multiple layers. The fusiformis multi-tiered application model is applied in the software development process. As a result of the experiment found that bugs in the software could be located more precisely, the development structure was more reasonable. So we think that the fusiformis-model has applacation value in the develoment on Web.

Abstract:
The Internet of Things (IoT) is an emerging Internet-based architecture, enabling the exchange of data and services in a global network. With the advent of the Internet of Things, more and more devices are connecting to the Internet in order to help people get and share data or program actions. In this paper, we introduce an IoT Agent, a Web application for monitoring and controlling a smart home remotely. The IoT Agent integrates a chat bot that can understand text or voice commands using natural language processing (NLP). With the use of NLP, home devices are more user-friendly and controlling them is easier, since even when a command or question/command is different from the presets, the system understands the user’s wishes and responds accordingly. Our solution exploits several available Application Programming Interfaces (APIs), namely: the Dialogflow API for the efficient integration of NLP to our IoT system, the Web Speech API for enriching user experience with voice recognition and synthesis features, MQTT (Message Queuing Telemetry Transport) for the lightweight control of actuators and Firebase for dynamic data storage. This is the most significant innovation it brings: the integration of several third-party APIs and open source technologies into one mash-up, highlighting how a new IoT application can be built today using a multi-tier architecture. We believe that such a tiered architecture can be very useful for the rapid development of smart home applications.

Abstract:
The adoption of Computer Based Testing (CBT) by Nigerian Tertiary Education Institutions has helped to address some of the challenges relating to the conduct of examinations and results processing. The most prominent of these challenges is the impersonation and to tackle these eventualities, multi-layered security architecture is implemented to ensure the authenticity of the student participating in the CBT. The architecture will assist Nigerian University administrators to effectively plan the conduct of CBT and develop in-house solution that will engender the reduction in the examination malpractices in CBT. The introduction of the facial capture reduced the intents of the students in engaging in the act of impersonation. The first security layer is the profiling of the registered students that are eligible to partake in the test, the second layer is the biometric capture to identify and authenticate that the student is the original person to partake in the test. The third layer is the facial capture on the system before the commencement of the test. The proposed system will be designed and implemented using algorithmic approach and a web-based application which will be deployed on the LAN of the institution. Therefore, this research presents the implementation of the multi-tiered layered security in mitigating the incidences of impersonation during CBT.

Abstract:
The currently emerging trend of building more complex web applications to solve increasingly more involved software problems has led to the the need for a more automated and practical means for deploying resources required by these advanced web applications. As web based applications become more complex and involve more developers, greater system redundancy, and a larger number of components, traditional means of resource deployment become painfully inadequate as they fail to scale sufficiently. The purpose of this research is to provide evidence that a more sound and scalable test and deployment process can be employed and that many of the components of this improved process can be automated and/or delegated to various system actors to provide a more usable, reliable, stable, and efficient deployment process. The deployable resources that have been included for their commonality in web based applications are versioned resources (both ASCII based and binary files), database resources, cron files, and scripting commands. In order to achieve an improved test and deployment process and test its effectiveness, a web-based code deployment tool was developed and deployed in a production environment where its effects could be accurately measured. This deployment tool heavily leverages the use of Subversion to provide the management of versioned resources because of its extensive ability to manage the creation and merging of branches.

Web sites become overloaded because of too many visitors. Increasing the request arrival rate prolongs the response time significantly. An admission control mechanism can prevent web sites from becoming overloaded by rejecting some requests and thereby maintains an acceptable response time. In this thesis, we implement an Apache module with admission control and develop a performance analysis tool. The control parameters are set by the analytic results from our tool. Measurements from multi-tier web application show that the module and control strategies can avoid web sites overload occurred.

Abstract:
The cost of creating and maintaining software and hardware infrastructures for delivering web services led to a notable trend toward the use of application service providers (ASPs) and, more generally, distributed application hosting services (DAHSs). The emergence of enabling technologies, such as J2EE and .NET, has contributed to the acceleration of this trend. DAHSs rent out Internet presence, computation power, and data storage space to clients with infrastructural needs. Consequently, they are cheap and effective outsourcing solutions for achieving increased service availability and scalability in the face of surges in demand. However, ASPs and DAHSs operate within the complex, multi-tiered, and open Internet environment and, hence, they introduce many security challenges that have to be addressed effectively to convince customers that outsourcing their IT needs is a viable alternative to deploying complex infrastructures locally. In this chapter, we provide an overview of typical security challenges faced by DAHSs, introduce dominant security mechanisms available at the different tiers in the information management hierarchy, and discuss open challenges

Abstract:
Software Architecture has evolved from simple monolithic system designs to complex, multi-tiered, distributed, and componentized abstractions. Service-driven architectural approaches have been a major driver for enabling agile, cost-effective, flexible, and extensible software applications and integration solutions that support the business dynamics of today’s fast-paced enterprises. SOA and the SCA model have been the typical Service-driven architectural approaches used in enterprises today, to tackle the challenges of developing and implementing agile and loosely coupled software and enterprise integration solutions. Recent trends involve the use of Web APIs and RESTful architecture in the enterprise for agile service development and application integration. The goal of this chapter is to explore, discuss, and recommend methodologies for Service-driven Computing in the enterprise. Service versioning is detailed as a primary architectural approach for accommodating modifications to services during their life cycle. Service Mediation, Enterprise Service Bus, and Composition mechanisms including Enterprise Mashups are explored. The chapter also presents the business value of APIs in the enterprise and investigates the value-add to Social Media and Cloud enterprise initiatives. The typical phases of a Service-driven development life cycle are explained and service design patterns to facilitate the engineering of flexible service-based applications are described. The chapter concludes with thoughts on future opportunities and challenges in the area of Service-driven computing.

Abstract:
This chapter describes the System for Population Kinetics (SPK), a novel Web service for performing population kinetic analysis. Population kinetic analysis is a widely-used tool for extracting information about the probability distributions of unknown parameters in kinetic models. The statistical population model is usually hierarchical, with a nested structure encompassing both variation between subjects and residual unexplained variation associated with the model predictions. The complexity of the analysis is largely driven by the nonlinearity of the models employed. Here, we provide a concise introduction to the topic and a historical perspective for the benefit of the reader who is new to these concepts. Next, we briefly describe the SPK open source system and its multi-tiered architecture, indicating the user goals it set to achieve and elucidating its practical usage with examples.

Abstract:
Web-based application development is a difficult task, since these applications include various features, like graphical interfaces, navigational structures, business models, and wireless communications, as well as other issues, such as serving a multitude of users, and the need for shorter development time. To overcome these complexities, it is indispensable to use web-based application designs and software architectures. In this paper, we use a multi-tiered, component based software architecture based on the J2EE technology. This technology separates the different parts of a complex application, and the development time is reduced through the use of components and distributed structure. Unfortunately, the J2EE technology lacks rich hypermedia and navigational structures, and the mapping of prepared designs to components is not carried out properly. For this reason, in this article, a combined architecture called OOHDM-J2EE is defined which uses the benefits of both schemes and solves the mentioned problems, provides the possibility of reuse, and further reduces the development time.

Abstract:
The product development processes nowadays are featured with ever-increasing complexity of product configurations, diverse data resources, and multi-disciplinary, geographical dispersed engineering teams, and intensive use of various software tools for managing the data associated with the product and its life cycle. These characteristics result in the need of a collaborative product development (CPD) environment for today’s industries. This paper describes the methodology which enables the engineering collaboration within a compressed product development cycle, and presents our results with the development of a CPD environment. A four-tiered client/server collaboration architecture, which allows system integration, data sharing, and collaboration among team members in an internet platform, is described. By integrating the distributed application servers, such as product specification server, CAD/CAE server, project management, collaborative visualization workspace, and product data management module, using web technologies, an engineering CPD portal is proposed and implemented. This portal environment could bring entire engineering team together in one place in real-time, irrespective of geography, enterprise boundaries, or native systems, to share product information throughout the product development processes, which include product definition, design, engineering analysis, and manufacturing, etc. Manufacturing companies could therefore collaborate closely with their suppliers/collaborators global widely. A case study is carried out for collaborative development of a typical component used in data storage industry, the spindle motor, to illustrate the proposed approach and to validate the developed systems.

Abstract:
The objective of this paper is to establish a concise structural model of the human musculoskeletal system (HMS) that can be used to clinically treat malfunctions or distortions of the human body. This model must be uncomplicated for therapists to identify the problematic areas of the human body with adequate visualization while maintaining a theoretical thoroughness in mechanics. To achieve this objective, a system theory approach called the Interpretive Structural Modeling (ISM) has been applied to bridge multi-body dynamics and clinical observations. From a mechanical engineering viewpoint, this HMS system can be treated as a collection of joint connected 15 rigid bodies in a topological tree configuration with 35 Degrees-of-Freedom (DOF). Alternatively, from a clinical viewpoint, the functioning of the joints is a major concern since most malfunctions or distortions take place around the joints. Based on 20 years of accumulated clinical observation data, we have discovered that all HMS movements can be constructed by a combination of 35 fundamental motion elements, all having a certain degree of interaction with each other. By applying the ISM for a matrix representation of the HMS system, we have obtained the following results: 1) The association between the rotation of the joints and the fundamental motion elements is represented by a square matrix of dimension N, where N is twice of the DOF 2) The determinant of this matrix, corresponding to the N-square matrix in SE terminology, gives an evaluation criteria in selecting the fundamental elements; 3) Application of the ISM reveals a distinction between an active motion element with intention versus an associated motion element that is induced by another motion element(s). In addition, the ISM yields a tiered structure of the fundamental motion elements according to the degree of activeness; and 4) most important, an overall investigation of the matrix characteristics gives a means to identify imbalances or distortions within the HMS. With the help of a motion diagram for the purpose of visualization, this research can eventually be applied to clinical observations whereby an automated identification of malfunctioning parts can be achieved with computer software. The above stated results will contribute to a holistic and non-invasive approach for medical care and rehabilitation.

Abstract:
Real-time monitoring of various components of a railcar such as wheel bearing temperature, brake line status, integrity of transported goods and many more has become a key focus area of research for the North American freight railroad industry. The ability for timely detection of abnormalities and impending failures prevents costly accidents, the potential loss of life and damage to the environment. Monitoring also increases overall operational efficiency, reliability and safety of freight railroads. Wireless Sensor Networks (WSN) are an obvious choice for implementing such a monitoring scheme. The accumulated data from various sensors distributed throughout each railcar along the length of the train is transmitted wirelessly using multi-hop transmissions to the locomotive for alerting and monitoring. From there, this information is also transmitted to dispatch centers for further analysis and recording. ZigBee technology based on the IEEE 802.15.4 standard is a popular choice among WSN communication protocols, owing to its low cost and low power requirements. ZigBee performance degrades severely in the long chain-like topology characteristic of the railroad application environment. This effectively disqualifies ZigBee as a candidate technology for such railcar monitoring deployments. To overcome these issues with ZigBee deployments for freight train monitoring we developed our Hybrid Technology Networking (HTN) approach [5–7]. HTN leverages both ZigBee and Wi-Fi communication to achieve reliable communication along an entire freight train. Railcar monitoring nodes are grouped into smaller clusters, within which we utilize ZigBee for its low-power operation and report to each cluster’s gateway node. The gateway nodes of all the clusters on a train communicate using Wi-Fi, to benefit from the high throughput and long communication range. This tiered architecture also results in a drastic reduction in overall hop count for end-to-end communication. In this paper we present HTNMote, a hardware platform that we are developing and employing for real-world evaluation of the HTN protocol. We also present results from our field tests of the HTNMotes at the Transportation Technology Center (TTCI) facility in Pueblo, Colorado, operated by the US Association of American Railroads (AAR). The results show that the use of HTN improves performance of the network by at least an order of magnitude compared to a ZigBee-only network. This paper details the design of our HTNMote platform, present the test setup and results, as well as conduct an in-depth analysis of the obtained results as they relate to railroad operations.
