Due to increasing demand, container terminals face the challenges of increasing its service capacity and minimize the time of ships loading and unloading. The assignment of storage locations for reshuffled containers is a problem to the efficiency of container terminals operations, as a wrong assignment may result in several future reshuffles. This paper proposes a meta-heuristic based on the Clonal Selection Algorithm to minimize reshuffle when retrieving containers from a stack. The model competitiveness in accuracy and time are established by extensive numerical experiments comparing with an existing Integer program model. The preliminary results obtained here suggest the proposed model is a promising optimization tool for the container stacking problem.

This paper proposes a robust multiplexed model predictive control (MMPC) for a bake plate control system. The bake plate is a multi-inputs multi-outputs (MIMO) system which is required to have uniform temperature. In bake plate sytem, the controller must be able to reduce the disturbances caused when placing a cold wafer inside. Results show that the proposed robust MMPC can outperform in attenuating disturbance compare with the MMPC and the standard MPC.

BlackBerry is not just an ordinary smartphone which rich in its multimedia features. BlackBerry also has very reliable internet services, include BlackBerry Messenger, e-mail, other instant messaging, and other internet service that Blackberry Internet Service (BIS) covers. However, there's an open question that all services that go through BIS is safe or not; considering the data includes text and files which is sent through BIS have to pass through the main server which is located in Canada. Therefor in this paper we chose to make software that can encrypt and decrypt text and even files, which will be sent through BlackBerry's internet or just to be stored in the BlackBerry device. In this paper, we use cipher block encryption algorithm with Cipher Feedback (CFB) 8-bit mode. This mode is chosen because it suits with the data inside BlackBerry device which is 8-bit aligned. The encryption algorithm uses cipher block encryption with 64-bit block size. We designed the algorithm based on Feistel network combined with some encryption/decryption algorithm. Then the cipher block encryption algorithm is implemented in software based on Java for BlackBerry. In this software development, we use the IDE Eclipse Ganymede with certain plugins. The expected result is software for BlackBerry capable to encrypt and decrypt some texts, either directly typed or saved as files on the BlackBerry device. This software also handles specific file types, such as picture and audio by preserving their file header, and also handles text encryption by transforming the ciphertext data to hex digits. After conducting some experiments, we conclude that the software has good compatibility with many kinds of BlackBerry devices and has good security level.

Generalized Enhanced Multivariance Product Representation for Data Partitioning: Constancy Level

引用

AIP Conference Proceedings 2011年第1期1389卷 1152-1155页

Enhanced Multivariance Product Representation (EMPR) method is used to represent multivariate functions in terms of less‐variate structures. The EMPR method extends the HDMR expansion by inserting some additional support functions to increase the quality of the approximants obtained for dominantly or purely multiplicative analytical structures. This work aims to develop the generalized form of the EMPR method to be used in multivariate data partitioning approaches. For this purpose, the Generalized HDMR philosophy is taken into consideration to construct the details of the Generalized EMPR at constancy level as the introductory steps and encouraging results are obtained in data partitioning problems by using our new method. In addition, to examine this performance, a number of numerical implementations with concluding remarks are given at the end of this paper.

The Algebraic Reconstruction Technique (ART) of Lambert-Beer's attenuation approximation for parallel rays transmission projection is a variant of the ART model that aims to solve image reconstruction problems in nuclear based computed tomography for non-destructive testing where γ or κ radiation is used as a ray source. In this model, the path length of the ray that hits a pixel at any projection view and the size of detector grid are explicitly included in computation. Then, the model is used to investigate the influence of the ray path length and the width of detector grid in producing image quality. The image quality is represented as space and pixel resolution, respectively. In this paper, we demonstrate that the model is able to show the contribution of the ray path length and detector grid in producing image quality. By considering ray path length and detector grid, the model produces smaller Root Mean Square error compared to conventional ART.

Basic Issues in Vector High Dimensional Model Representation

引用

AIP Conference Proceedings 2011年第1期1389卷 1143-1146页

作者： Burcu Tunga Metin Demiralp aIstanbul Technical University Faculty of Computer and Informatics Maslak 34469 Istanbul Turkey bIstanbul Technical University Informatics Institute Computational Science and Engineering Program Maslak 34469 Istanbul Turkey

A multivariate modelling may involve a set of multivariate functions. A vector valued function structure can be used to mathematically express the given problem and each multivariate function can be considered as an element of this vector. This work aims to construct a new approach representing the elements of this vector structure in terms of less‐variate functions to reduce the computational complexity. For this purpose, a new method based on the plain High Dimensional Model Representation (HDMR) philosophy is developed. The basic concepts of this method and several illustrative numerical implementations are given here.

Software development is a series of processes activity involving more than one person, especially in medium to large software projects. Each activity of software development is carried out by various combination of different individual. Collaboration occurs in every phase of the process software development. The right team collaboration method is one of the important things in success software development. This research is focused to develop collaboration model of software development to meet time schedule, budget, scope, and software quality. The collaboration model of software development is generated from survey of collaboration method (about face to face and virtual collaboration) and software development methodology especially agile methodology. The direct collaboration was used in the software specification processes, and combination (with a direct and virtual) collaboration was used during software design, implementation, and validation. Team coordination in every process of software development was done with face to face method. The same artifacts were used in this collaboration model with some collaboration software tools. Combination between face to face and virtual communication was used in this model. The model is implemented in small case software development project. During the software development, some measurement is carried out. The measurement included the measurement of project completion time, cost, software specification, and software quality. The software is developed in time schedule (two months), cost under budged, and meet specification. In addition, the software has built a fairly good quality. Thus, this collaboration model good use in software development to achieved accuracy of schedule, cost, scope, and quality.

Communities in social networks emerge from interactions among individuals and can be analyzed through a combination of clustering and graph layout algorithms. These approaches result in 2D or 3D visualizations of clustered graphs, with groups of vertices representing individuals that form a community. However, in many instances the vertices have attributes that divide individuals into distinct categories such as gender, profession, geographic location, and similar. It is often important to investigate what categories of individuals comprise each community and vice-versa, how the community structures associate the individuals from the same category. Currently, there are no effective methods for analyzing both the community structure and the category-based partitions of social graphs. We propose Group-In-a-Box (GIB), a metalayout for clustered graphs that enables multi-faceted analysis of networks. It uses the treemap space filling technique to display each graph cluster or category group within its own box, sized according to the number of vertices therein. GIB optimizes visualization of the network sub-graphs, providing a semantic substrate for category-based and cluster-based partitions of social graphs. We illustrate the application of GIB to multi-faceted analysis of real social networks and discuss desirable properties of GIB using synthetic datasets. © 2011 IEEE.
