Informative Gene Selection Using Adaptive Analytic Hierarchy Process (A2hp), Abhishek Bhola, Shafa Mahajan Jun 2020

Informative Gene Selection Using Adaptive Analytic Hierarchy Process (A2hp), Abhishek Bhola, Shafa Mahajan

Future Computing and Informatics Journal

Gene expression dataset derived from microarray experiments are marked by large number of genes, which contains the gene expression values at different sample conditions/time-points. Selection of informative genes from these large datasets is an issue of major concern for various researchers and biologists. In this study, we propose a gene selection and dimensionality reduction method called Adaptive Analytic Hierarchy Process (A2HP). Traditional analytic hierarchy process is a multiple-criteria based decision analysis method whose result depends upon the expert knowledge or decision makers. It is mainly used to solve the decision problems in different fields. On the other hand, A2HP is …


A New Method To Reduce The Effects Of Http-Get Flood Attack, Hamid Mirvaziri Jun 2020

A New Method To Reduce The Effects Of Http-Get Flood Attack, Hamid Mirvaziri

Future Computing and Informatics Journal

HTTP Get Flood attack is known as the most common DDOS attack on the application layer with a frequency of 21 percent in all attacks. Since a huge amount of requests is sent to the Web Server for receiving pages and also the volume of responses issued by the server is much more than the volume received by zombies in this kind of attack, hence it could be done by small botnets; in the other hand, because every zombie attempts to issue the request by the use of its real address, carries out all stages of the three-stage handshakes, and …

Future Computing and Informatics Journal

Genes of an organism play a very crucial role in the working of various cellular activities. Genes and other biological molecules like DNA, RNA do not operate alone but they all are correlated. Their relationships are shown with the help of networks commonly known as Gene Regulatory Networks. Gene Regulatory Networks are complex control networks that show the map of interactions among the genes. They provide very useful contribution to the genomic science and increase the understanding of various biological processes. In this paper, fuzzy logic based method is proposed for the reverse engineering of gene regulatory network from microarray …


Wavelet Based Transition Region Extraction For Image Segmentation, Priyadarsan Parida, Nilamani Bhoi Jun 2020

Wavelet Based Transition Region Extraction For Image Segmentation, Priyadarsan Parida, Nilamani Bhoi

Future Computing and Informatics Journal

Transition region based approaches are recent hybrid segmentation techniques well known for its simplicity and effectiveness. Here, the segmentation effectiveness depends on robust extraction of transition regions. So, we have proposed a transition region method which initially decomposes the gray image in wavelet domain. Two existing transition region approaches are applied on approximate coefficients to extract transition region feature matrix. Using this feature matrix the corresponding prominent wavelet coefficients of different bands are found. Inverse wavelet transform are then applied on the modified coefficients to get edge image with more than one pixel width. Otsu thresholding is applied on it …

Forecasting Of Nonlinear Time Series Using Ann, Ahmed Tealab, Hesham Hefny, Amr Badr

Future Computing and Informatics Journal

When forecasting time series, it is important to classify them according linearity behavior that the linear time series remains at the forefront of academic and applied research, it has often been found that simple linear time series models usually leave certain aspects of economic and financial data unexplained. The dynamic behavior of most of the time series in our real life with its autoregressive and inherited moving average terms issue the challenge to forecast nonlinear times series that contain inherited moving average terms using computational intelligence methodologies such as neural networks. It is rare to find studies that concentrate on …

A Cloud Interoperability Broker (Cib) For Data Migration In Saas, Hassan Ali, Ramdan Mowad, Amira Farouk Jun 2020

A Cloud Interoperability Broker (Cib) For Data Migration In Saas, Hassan Ali, Ramdan Mowad, Amira Farouk

Future Computing and Informatics Journal

Cloud computing is becoming increasingly popular. Information technology market leaders, e.g., Microsoft, Google, and Amazon, are extensively shifting toward cloud-based solutions. However, there is isolation in the cloud implementations provided by the cloud vendors. Limited interoperability can cause one user to adhere to a single cloud provider; thus, a required migration of an application or data from one cloud provider to another may necessitate a significant effort and/or full-cycle redevelopment to fit the new provider's standards and implementation. The ability to move from one cloud vendor to another would be a step toward advancing cloud computing interoperability and increasing customer …


Fixing Rules For Data Cleaning Based On Conditional Functional Dependency, Asmaa Abdo Jun 2020

Fixing Rules For Data Cleaning Based On Conditional Functional Dependency, Asmaa Abdo

Future Computing and Informatics Journal

Most existing databases suffer from data inconsistencies. Enhancing data quality efforts are necessary to resolve this issue. In this paper, two techniques are proposed for mining accurate conditional functional dependencies rules from such databases to be employed for data cleaning. The idea of the proposed techniques is to mine firstly maximal closed frequent patterns, then mine the dependable conditional functional dependencies rules with the help of lift measure. Moreover, data repairing algorithm is proposed for fixing inconsistent tuples found in the database exploiting the generated rules. An extensive experimental is conducted study to confirm the effectiveness of the proposed techniques …

A Shape Grammars Approach To Bvlgari’Semerald Necklaces Design Language, Youssef Elrafie, Samir S. Hosny, Mohamed Eladly, Sahar Morsy

Future Engineering Journal

For more than forty years now, shape grammars have been the interest of many researchers in many domains including Paintings and Arts, Architecture, and Product Design [March, 2011]. However, by tracing the time line of shape grammars under “Product Design”, it does not show any interest in “Antiques or Vintages” as such [Chau et al. 2004]. This paper addresses shape grammars as a style generator of Bulgari’s emerald necklace designs, being considered as a vintage that bears a specific style, character and importance as a cultural symbol. The paper discusses the issue of style in design. Then it presents an …

The column section consists of two back to back sigma cold formed sections. The two sections are connected through their webs with connecting fasteners. Eight specimens with variable …


Origins Of Computational Design In Architecture, Ossama Mohamed Al-Rawi Mar 2020

Origins Of Computational Design In Architecture, Ossama Mohamed Al-Rawi

Future Engineering Journal

The changes that the computer is bringing to architecture are one part of a revolutionary social upheaval. Tools not only change individual patterns and behaviour, but also cause transformations in institutions. Just as other tools have in the past, the computer is in the process of conditioning our understanding of the world and our perception of our place in it. The application of computers to architecture is more than anew sophisticated tool that can be manipulated like a pencil or pen. It is rather, “the culmination of the objectifying mentality of modernity and it is, therefore, inherently perspectival. The tyranny …
