...important component of IT infrastructure. Within the healthcare industry, the value of an efficient and stable network is immeasurable. The challenge in most industries, especially healthcare, is address security concerns and the rights of the patience. Patton-Fuller Community Hospital, located in the City of Kelsey, is a fully function hospital servicing the local area since 1975. Recently, The Chief Executive Officer (CEO) of Patton-Fuller Community Hospital expressed the desire to design an upgrade to the current network architecture. This design will include upgrades to hardware components and software components. This proposal will discuss and summarize the current network structure, propose an upgrade design to meet future challenges while addressing network security and compliance; more specifically, the transfer and confidentiality of patient records information. Patton Fuller Community Hospital – Current Network The current networking architecture of the Patton-Fuller Community Hospital can be broken down into two major sections. Today the two major backbones of the network include a 1000 Base T using CAT6 cable which provides network access to many administrative and operational areas of the facility. Executive management, Human Resources, Operations, Facilities, Finance, as well as the IT data center are all connected directly to this side of the network backbone. The hospital side is connected via 1000 Base F which uses fiber optics to ensure the very highest...

...DESIGN AND ANALYSIS OF A CHASSIS FOR A 60 TON PAY LOAD Abstract: As the chassis frame forms the backbone of a heavy vehicle, its principal function is to safely carry the maximum load for all designed operating conditions. To achieve a satisfactory performance, the construction of a chassis is the result of careful design and rigorous testing. Various manufacturers have individual design concepts and different methods of achieving the desired performance standards for the complete chassis, not all chassis components are interchangeable between various makes and models of vehicles. So, there is no standard design for chassis frame. Even though start with the chassis frame design start with selection of the section for side rails and cross members. In this paper we have designed a chassis for storage cum resting fixture. Storage cum resting fixture is a structure of length 11000mm & width 2300mm, used to store cylindrical specimens of various sizes and weights in horizontal configuration. The storage cum resting fixture is used to carry the propellant stored in the cylindrical specimens. The trolley fixture should be designed for a maximum pay load of 60 tons. The Objective of my project is to design a chassis for a pay load of 60 Tons. The design process involves manual design calculations, 3d modeling using UNIGRAPHICS software and analysis to validate the design. Ansys package has been implemented to perform the structural analysis. ...

Section IV presents the models developed to represent a mobile cloud system. A case study is described in Section V, with the results obtained through model analysis. Section VI concludes the paper, presenting also some possible future works. II. BACKGROUND Abstract—Mobile cloud computing refers to abstraction of computational power to outside of the mobile device, processed in the “clouds”. This paper provides an availability and energy consumption study using hierarchical heterogeneous modeling. Different scenarios were analyzed considering wireless communication technologies, such as 3G and WiFi. The results shows that the 3G protocol causes a lower availability and is the greater responsible for the discharge of battery, but when is combined with WiFi protocol providing communication redundancy, we have the best results of availability and better results of uninterrupted operation time of battery...

...recommendations to the company about deploying a SAN at each branch office, since each office uses data, audio, video and graphic files that are shared by staff at each location. The SAN may incorporate NAS devices which we have evaluated with different vendors. As we conducted a further research in order to provide you with more detail specifications on SAN and NAS solutions, we were able to come up with the following information design in a form of questions and answers. What is required to implement a SAN and /or NAS? Storage-area networks (SANs) are composed of computers and remote storage devices. The computers are typically connected to the remote storage devices using SCSI over Fibre Channel (see Figure 1). Other implementations of SAN exist, but this is the most common. In a SAN, all the storage appears local, just as if the remote disk were directly connected to the computer and physically located inside the computer chassis. Network-attached storage (NAS) devices appear to the user as a remote drive letter or are named remote storage device. Typically, the operating system employs a protocol such as Network File System (NFS) or Common Internet File System (CIFS) to discover, log in, and transfer content to and from a storage device. NFS and CIFS both communicate over Ethernet. The user typically enters a username and password, and then is granted access to a particular device. Figure 1. SAN and NAS use different protocols and transports. Click here to see an enlarged diagram...

...CHAPTER I Project Title Proposed Computer Virtualization of NEUST-Gabaldon Computer Laboratory Using Thin-Client Network Project Description NEUST-Gabaldon Campus (Formerly Sabani Estate Agricultural College) established their computer laboratory on 2011 which help the students of College and High School for their computer subjects (Office Productivity). Since then, the computer laboratory has its computer administrator in presence of Mr. Jefrain M. Padre, although there was computer network architecture in the campus there were times that the computer had some troubles including the System Unit and its operating system. So, the researchers decided to make a proposal entitled “Proposed Computer Virtualization of NEUST-Gabaldon Computer Laboratory Using Thin-Client Network”. The proposed project used virtualization for it was essentially lets one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments. Using an Ncomputing M300 (thin-client) series connection of network it was possible for the entire project. Thoroughly, the entire project covered up network of computer using this device (Ncomputing M300 series) to connect through a server in a series type of network. Also, using a server with a high specification it will then try to run at least one programming language that can be used by the Bachelor of Science in Information Technology students of Gabaldon Campus.

Foreword omputer networks are having dramatic impacts on our lives. What were once esoteric tools used only by scientists and engineers are becoming more widely used in schools, libraries, and businesses. At the same time, researchers are working to develop even more capable networks that promise to change fundamentally the way we communicate. This background paper analyzes technologies for tomorrow’s information superhighways. Advanced networks will first be used to support scientists in their work, linking researchers to supercomputers, databases, and scientific instruments. As the new networks are deployed more widely, they will be used by a broader range of users for business, entertainment, health care, and education applications. The background paper also describes six test networks that are being funded as part of the High Performance Computing and Communications Program. These test networks are a collaboration of government, industry, and academia, and allow researchers to try new approaches to network design and to attack a variety...
