eGovernment Whole-of-Government Approach for Good Governance: The Case of the System GID in Morocco
by Azelmad Said
Abstract: Public administration reforms, in Morocco, called for the use of ICTs tornconnect administrations in a Whole-of-Government Approach, building a culturernof collaboration and Good Governance. Indeed, Coordination Theory supportsrnthe networked bureaucracy, as a catalyst for heterogeneous multi-stakeholderrnmanagement, internal auditing and synergy. Institutional networkedrncoordination is believed to increase interoperability and integration among offices for transparency and mutual accountability. A mutual collaboration (G2G) that is deemed to better governance, streamline workflows and reduce duplication of workflows and tasks. However, stove-piped management remains always a badrnomen for networked governance for its single-purpose management. It isrnbelieved to separate offices in corrupted dispersed silos and bureaucracies,rnoperating in ambiguity, red tape and bad governance. Results from an onlinernsurvey of public agents, using the GID system in Morocco (n =253) was used to empirically analyze the effect of eGovernment Whole-of-Government Approach on Good Governance ethics in back offices, using PLS-SEM.

A Double-controller Fuzzy Scheme for Intelligent Resource Discovery on IaaS Cloud Systems
by Mohammad Samadi Gharajeh, Babak Jahangir
Abstract: The resource discovery process discovers appropriate computing resources (e.g., shared memory) in Infrastructure as a Service (IaaS) cloud systems according to user requirements. Since fuzzy systems use intelligent procedures based on humanistic experiences, they can be used in cloud computing to increase the number of completed jobs and improves the success rate. This paper proposes a double-controller fuzzy scheme for intelligent resource discovery in IaaS cloud systems, called DOCFIR. This scheme applies two fuzzy controllers to perform the intelligent resource discovery across the network. The first controller determines the number of virtual machines in the deployment phase based on the most important characteristics of the physical machines. The second controller discovers the appropriate computing resources for the users job in the service phase based on characteristics of the physical machines and user requirements. The simulation results show that the proposed scheme surpasses some of the existing related works in terms of the number of completed jobs and success rate.

Understanding Customers Continuous Intention to Use of Social Commerce via Facebook: A Theoretical Model and Empirical Examination
by Fadi Herzallah, Mohannad Moufeed Ayyash
Abstract: Although electronic commerce (E-commerce) issues have attracted researchers' attention, social commerce (S-commerce) studies remain limited in information systems (IS) continuous intention literature. So far, no study has investigated whether customers intend to continuously use S-commerce via Facebook based on Expectation-Confirmation Model (ECM) information systems (IS) in combination with S-commerce constructs derived from the literature review as a research model. Therefore, the current study proposes a model examining the impact of ECM-IS factors in combination with S-commerce constructs to better understand the incentives behind customers' continued use of S-commerce via Facebook in Palestine. The proposed model was tested by administering a survey to a number of 218 customers. The data was analyzed using Structural Equation Modelling (SEM). The findings revealed that perceived usefulness and S-commerce constructs positively impact customers' satisfaction and continuous intention to use. Moreover, expectations of confirmation positively influence satisfaction and perceived usefulness. Customers' satisfaction positively impacts continuous intention to use; satisfaction is a more powerful determinant of continuous intention to use than perceived usefulness and S-commerce constructs. The findings can be used by S-commerce service providers' and policymakers in formulating strategies toward proliferation customers' continuous intention to use and can be useful for scholars to increase, improve and assess research on S-commerce field.

Identifying DDOS Attacks in 4G Networks using Artificial Neural Networks and Principal Component Analysis
by Nagesha A G, Mahesh G, Gowrishankar S
Abstract: Abstract: Denial-of-Service (DoS) attack is one in which attackers make certain queries by sending messages to the remote or target servers with an intention to stop or shutdown the servers. Those messages causes such an impact to the servers that it makes no response for the users. When this DoS attack is performed using number of systems that are compromised for attacking a single system, then it is called as Distributed Denial-of-Service (DDoS) attack. In this paper an Artificial Neural Network (ANN) combined with Principal Component Analysis (PCA) is used to identify the traffic as normal or a DDoS attack in 4G networks. The feature space dimension is reduced using PCA and the dimensionally reduced features are given as input to the feed forward neural network for training. The experiment is conducted using KDD dataset. The recognition accuracy of the proposed system is improved when compared to the existing systems using RBF Networks, Naive Bayes and Random Forest.

A SECURE ENERGY EFFICIENT EVENT DETERMINATION ALGORITHM FOR UNDERWATER WIRELESS SENSOR NETWORKS
by INDULEKSHMI S. KAIMAL, BINU G S
Abstract: Effective routing in Under Water Sensor Networks (UWSNs) is a highly demanding task because of the weak radio channels in water and the changing topology of sensors that maneuver indifferently with water. Energy efficient Derivative Based Prediction (DBP) approach has been proposed to reduce the amount of messages required for transferring the data samples from a wireless sensor node to a base station. However, predicting sensor data is not effortless for underwater channels as they are prone to wormholes attack due to the inconsistent propagation delays. In this paper, an enhanced empirical data predicting method that not only predicts sensor data but also the topographical movements of the sensor nodes is presented. Further, a security aware locally restrained algorithm RDV-HOP is proposed to assess the influence of paths to other broadcaster nodes and to transmit the collected information to the network. The Advanced Encryption Standard (AES) algorithm is used to protect the confidentiality of data. The proposed method demonstrates a significant benefit in managing the dynamic networks with better energy efficiency even with extensive number of attackers. Extensive simulations were performed with variable number of wormhole attackers and the results show higher packet delivery ratio with reduced delay.

by Zhiqiang Gao
Abstract: With the development of national economy, the level of science and technology and the improvement of peoples living standard and amount of urban data expands at the geometric multiple growth rate, and more and more complex buildings. Therefore, the traditional two-dimensional plane data is difficult to meet our data needs for such a complex urban system. BIM model has been applied to many fields, such as building engineering, model visualization and indoor path planning. However, the BIM model has no description of geographic information, resulting in the limited application of the model in the space. The concept of smart city originated from "smart earth". "Smart earth" refers to the formation of Internet of things and Internet connection in various media such as hospitals, power grids, railways, etc. to achieve the integration of human society and physical systems. In practical application, speech recognition is usually combined with the natural language understanding, natural language generation and speech synthesis technology to provide a natural and smooth human-computer interaction platform based on speech. This paper constructs a BIM data fusion framework based on speech recognition model with sustainable computing. Experimental results show that this method can effectively analyze BIM data and obtain satisfactory result.

by Shinly Swarna Sugi, Raja Ratna S
Abstract: Feature selection plays a vital role in toning down the effects of the curse of dimensionality in the humungous datasets seen in Intrusion Detection. Feature Selection Algorithms are used to pick the relevant features and averts the extraneous and repeated features from the dataset to improve the efficiency. It can reduce processing time, dimension of data and enhance the performance of the system in terms of precision and training time. This paper proposes a variant of SVM, known as SVM Correlation Algorithm (SVM-CA) to choose the relevant features. The combination of Support Vector Machine with correlation algorithm enhances the classification accuracy. Our proposed SVM-CA algorithm deals with the problems faced by the existing algorithm like low accuracy and high detection time. The performance of the algorithm is appraised by five parameters including the modeling time, true positive rate (TPR), false positive rate (FPR), false negative rate (FNR) and accuracy. The experimental results show that our proposed technique decreases the false positive rate and processing time.

Framework Design of Urban Traffic Planning Based on Wireless Network Optimization and Cognitive Sustainable Data Retrieval
by Gang Zhang, Tiechun Li
Abstract: With the acceleration of urban development in China, the development of urban traffic system should be improved. Therefore, there are many problems such as traffic congestion, resource shortage and environmental pollution. Transportation is one of most basic needs for the survival and development of human society. Urban traffic planning is of great significance to the sustainable development of modern cities. It should be noted that urban traffic planning is only a part of urban planning, but there is a very close relationship between them. If in the process of urban traffic planning, the value of urban traffic planning can not be brought into full play if the coordination relationship between them is not clarified. In order to avoid the above problems, traffic management departments have established various traffic management information systems with the help of wireless network optimization technology. The data structure and supported data types of each system are also different, which results in the operation of "island" management information system, therefore, this paper constructs a framework of urban traffic planning based on wireless network optimization model and cognitive sustainable data retrieval. We optimize the communication model to construct the efficient system.

by Hanxiao Li
Abstract: As a treasure of human civilization, painting art has immeasurable artistic value. However, due to the influence of human factors, accidents and natural environment, there are different degrees of damage. Traditional image acquisition is based on RGB three channel chroma information acquisition, which can not objectively represent the color information of painting works. In the research of computational aesthetics, it is necessary to analyze the high-resolution images of paintings. However, most of the actual paintings are low resolution, so this paper studies the influence of the quality of painting images on the visual art analysis effect. Nowadays, wireless network is widely used and has become the main way of user terminal access to the network. With the rapid development of wireless network services, especially the development of mobile services, the performance requirements of data transmission under wireless networks are becoming higher and higher. Based on the development of wireless network transmission technology, this paper studies the image quality analysis system of visual art painting. The designed system is validated through different scenarios. The experimental results have proven the effectiveness.

A Cluster Workload Forecasting Strategy Using A Higher Order Statistics Based ARMA Model For IaaS Cloud Services.
by Zohra AMEKRAZ, Moulay Youssef Hadi
Abstract: With the cloud computing services becoming more popular among Internet users, cloud providers are facing a challenge in allocating resources to users according to demand instantly. The delay caused by the Virtual Machines (VMs) start up time makes the reactive techniques, which allocate new resources only when a given load threshold is attained, not effective for the allocation process. An interesting alternative to the reactive technique is the proactive technique. This latter consists of predicting the future demand known as workload and allocating or releasing resources in advance to prevent any overload to occur and also to reduce any related costs. In this paper, we introduce an adaptive workload prediction method based on the use of Higher Order Statistics (HOS) and Autoregressive Moving Average (ARMA) model. The proposed method uses the HOS to make a Gaussianity checking test of the cloud workload and then decides the suitable identification method of the ARMA model to be used to forecast the workload. Furthermore, the proposed method updates the parameters of the ARMA model constantly whenever new workload data are available. We evaluate our proposal with two real workload traces extracted from cluster workloads. The results show that the proposed method has an average of 34% higher accuracy than the baseline ARMA model and presents a low overhead for forecasting incoming workload (<2 s).

Cloud Spot Price Prediction Approach Using Adaptive Neural Fuzzy Inference System With Chaos Theory
by Zohra AMEKRAZ, Moulay Youssef Hadi
Abstract: The dynamic pricing of cloud computing is a major challenge for cloud
users all over the world. This challenge was first addressed by Amazon under the
name of Amazon Spot Instance Market. Cloud users can bid for a spot instance
using this market and obtain the requested spot if their bids exceed a dynamically
changing spot price. Amazon publicizes the spot price but does not reveal how
it is determined. In this paper, we perform chaotic time series analysis over the
spot price trace.We also develop a chaos based Adaptive Neural Fuzzy Inference
System (ANFIS) model based on phase-space vectors obtained during the phase
of chaotic analysis. Next, we study the effect of chaos existence on the prediction
accuracy of the spot price by comparing the proposed chaos-ANFIS model with
the baseline ANFIS model (non-chaotic approach). Evaluation results show that
the proposed chaos-ANFIS model yields better predictions of spot price compared
to the baseline ANFIS model in terms of Root Mean Square Error (RMSE) and
Mean Absolute Percentage Error (MAPE).

by Roseline Oluwaseun Ogundokun, Muhammad Daniyal, Sanjay Misra, Joseph Bamidele Awotunde
Abstract: Learning and teaching online is not a modern concept. It has been seen primarily as a part of face-to-face teaching and learning purposes for the past few years. Evaluation is an important aspect of teaching and learning since it determines the students' accomplishment of course learning outcomes. Today due to the coronavirus outbreak, there's a peculiar issue facing the global education community. The government and educational policymakers have to find other ways of teaching and learning to help learners during this isolation period at all locations; thus, learners need to be literate and be able to use online technologies effectively and consider ever-changing dynamics. Therefore, the study aims to explore whether students of the developing countries are contented with the innovation of online education introduced by all higher establishments worldwide as a result of the new coronavirus called COVID-19. This study evaluates the effect of online teaching during COVID-19 lockdown on students in the developing country like Nigeria. An online survey was conducted between 1st October and 8th October 2020 to achieve this evaluation. A 'Google form' structural questionnaire was forwarded to scholars via WhatsApp and e-mail. A total of 1419 students submitted complete survey information. These are evaluated to discover their thoughts on online education during the COVID-19 outbreak in a developing country as Nigeria. The study findings highlighted that an overwhelmingly greater number of the scholars are incapable of connecting to the net owing to technological and fiscal problems, thereby made online learning not to be able to yield desired results. In a group of few additional concerns emphasized by university scholars is the absence of one-on-one contact with the teacher, reaction period and nonappearance of typical teaching space socialization.

Stock Movement Prediction Using Neuro Genetic Hybrid Approach and Impact on Growth Trend due to COVID-19
by Pradeepta Kumar Sarangi, Kalpna Guleria, Devendra Prasad, Deepak Kumar Verma
Abstract: Knowing the future perspective is a matter of great concern for every business organization. Its importance increases when it comes to the matter of financial data related to the stock market. Researchers apply various methods to predict the stock trend but still there is no method that can guarantee the accurate stock movement whereas a nearly accurate approach could be achieved in case of short-term stock movements. Artificial Neural Network (ANN) is one of the most popular methods to analyze the stock trend and forecast the future direction of the stock market and the most challenging task in using the neural network is the selection of a proper architecture, input parameters and training of the network. This can be overcome by analyzing the relationship between independent and dependent factors and also by implementing hybrid models such as ANN with Genetic Algorithm (GA) for network training. This work has addressed this issue for short term stock prediction and is divided into two phases. In phase-I, experiments have been done to implement a hybrid ANN-GA model for short term stock prediction and in phase-II, a study has been carried out to analyze the impact of the COVID-19 on the share prices of selective major banks in India.

There has been a widespread investment in BIM by clients prior to commencement of new projects, pre construction analysis, interior designing and post construction. Since BIM is a recent trend, the motivation for the proposed work has been derived an exhaustive literature survey in key areas for research contributions which could greatly increase the quality and importance of BIM. The proposed work focuses on the input side of BIM system involved with acquisition and processing of information before being exported into the database management system. 3D to 2D modelling and feature extraction has been proposed in this paper with dimensionality reduction technique which drastically reduces the feature data set before being exported in to the BIS management system. A Principal component analysis (PCA) has been implemented in this paper and the two dimensional features have been exported into the BIM database. The most appropriate texture image is selected from aerial images according to geometry between building faces and external parameters of thephotos. The method has been tested with LIDAR data of two building images and extraction accuracy determined.
Keywords: 3D image modelling and extraction; Polgonization; multi resolution approximation; feature import in BIS.
