...Data Warehousing Methodologies Using a common set of attributes to determine which methodology to use in a particular data warehousing project. DATA INTEGRATION TECHNOLOGIES have experienced explosive growth in the last few years, and data warehousing has played a major role in the integration process. A data warehouse is a subjectoriented, integrated, time-variant, and nonvolatile collection of data that supports managerial decision making [4]. Data warehousing has been cited as the highest-priority post-millennium project of more than half of IT executives. A large number of data warehousing methodologies and tools are available to support the growing market. However, with so many methodologies to choose from, a major concern for many firms is which one to employ in a given data warehousing project. In this article, we review and compare several prominent data warehousing methodologies based on a common set of attributes. Online transaction processing (OLTP) systems are useful for addressing the operational data needs of a firm. However, they are not well suited for supporting decision-support queries or business questions that managers typically need to address. Such questions involve analytics including aggregation, drilldown, and slicing/dicing of data, which are best supported by online analytical processing (OLAP) systems. Data warehouses support OLAP applications by storing and maintaining data in multidimensional format. Data in an OLAP warehouse is extracted and loaded...

...Holography is a method which allows three-dimensional images to be made. It includes the use of a laser, interference, diffraction, light intensity recording, and suitable illumination of the recording. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object are still present, therefore making it three-dimensional. The projector that will be used in this project is a overhead projector. An overhead projector is a variation of the common slide projector that is used to display images to a group of people. II. Project Description Hologram Projector is a projector wherein it can reflect the full dimension of an image. It consists of a laser, interference, and diffraction, light intensity recording and suitable illumination of the recording. Hologram Projector is AC operated. It projects special white light or laser light. The light produces two- and three-dimensional images. Authentic 3-D images require laser-based holographic projectors. It can be presented from different angles and can be seen in true perspective. III. Process Description To come up with the Hologram projector’s design wasn’t easy. The group had to go through several brain-storming sessions and researches to come up not only with an appropriate but also a hi-end design that will embody the concept of the new technology. The drafts of the prototype’s design were drawn in a three-dimensional view. The designs created varied from rectangular to...

...OPTIMIZATION OF TWO DIMENSIONAL PHOTONIC CRYSTAL BAND GAP USING INDIUM PHOSPHIDE(InP) A thesis submitted in partial fulfilment of the requirements of Staffordshire University for the degree of Master of Science in Electronics Engineering Faculty of Computing, Engineering & Technology DECEMBER 2010 ABSTRACT Photonic crystals exhibit periodic structure and these are of many types such as one, two and three dimensional photonic crystals. Photonic crystal is a low loss periodic dielectric medium. In order to cover all periodic directions the gap must be extend to certain length which is equivalent to semiconductor band gap. The complete photonic band gap occurs in the three dimensional photonic crystals. The propagation of light which is confined to a particular direction can be analysed through Maxwell’s approach. The electromagnetic wave which contains both ‘E’ and ‘H’ fields can be calculated through these equations. These field vectors are more useful in calculating band structure of photonic crystal. This report deals with the calculation of band structure in two-dimensional photonic crystal. There are many methods for calculating band structure and this thesis is mainly focused on the plane wave expansion method. This report contains the simulation procedure for calculating band structure for both TE and TM modes in the presence of dielectric medium using Computer Simulation Technology (CST) microwave studio. Results which are obtained during the simulation provide...

...An Extended Entity-Relationship Model for Geographic Applications * Thanasis Hadzilacos Computer Technology Institute, University of Patras Box 1122, GR-26110, Patras, Greece thh@cti.gr Nectaria Tryfona National Center for Geographic Information and Analysis Univ. of Maine, Orono, ME 04469-5711, U.S.A nectaria@spatial.maine.edu Abstract. A special-purpose extension of the EntityRelationship model for the needs of conceptual modeling of geographic applications, called the Geo-ER Model, is presented. Handling properties associated to objects not because of the objects’ nature but because of the objects’ position, calls for dealing -at the semantic modeling levelwith space, location and dimensionality of objects, spatial relationships, space-depending attributes, and scale and generalization of representations. In order to accomplish this in the framework of ER and its derivatives, we introduce special entity sets, relationships, and add new constructs. The rationale as well as examples of usage of the Geo-ER model from actual projects are presented. 1. Introduction Is everybody special or are we all alike? Should we develop applications according to a special methodology for each class of applications, such as medical, business process and geographic, or should we use a single blanket approach for all? Personal preferences and philosophical discussions aside, it does seem that the general purpose side has won most battles in computer science, from hardware to programming languages...

...consequences of the emergence of that particular technology play important roles in relating the context. This paper focuses on two major expanding technologies; mobile phones and 3D printing. 1.1. Introduction to 3D printing Three dimensional printing â_œemploys an additive manufacturing process whereby products are built on a layer-by-layer basis, through a series of cross-sectional slicesâ__ (Berman, 2012, para.2). 3D printing is compromised of various other technologies and the commonly used software is the Computer aided design also known as CAD. 3D printing is a developing concept that is yet to bring a lot of new creations into the world of technology. 1.2. Introduction to Mobile phones Mobile phone is a mobile device traditionally used to make and receive calls. There are many categories in mobile phones. For example, smartphone is â_œa category of mobile phones that read email, take pictures, and surf the internet in addition to making and receiving callsâ__ (Flew & Smith, 2011, p.72). Because of the advancement of the mobile phone technology, majority of the population use them in their day to day activities and mobile phones play a vital part in peopleâ_™s lives. 1.3.

...University 3D printing economic questions and considerations Definition Three dimensional printing refers to a procedure that employs the formation of solid three dimensional objects that can take the form of any shape desired based on the designs of a digital model. In order to achieve a three dimensional print output, one is required to utilize the additive procedure that involves the use of successive material layers that are laid in arrangement such that different shapes are displayed. There have been considerations of three dimensional printing as technique of traditional machining that greatly relies on material removal through use of methods such as drilling and cutting which is part of the subtractive procedure. I) History of 3D printing technology The historical development and context of 3D printing technology Three dimensional printing has existed for over thirty years, long before it was popularized. From the 1980s this technology utilized the inclusion of a layer fused in powdered material with the combination of a laser as well as dispersion of plastic that was melted through a nozzle system and resin that was photo-cursed. Nonetheless, three dimensional printers remained expense ice and where characterized as being sluggish with inefficiencies as the industry redeveloped at a slow pace during that era (Lanzetta & Sachs, 2003). The rapid popularization and growth of three dimensional printing begun only after the start of the twenty first century as several...
