Published: April 2020

There has been a great deal of discussion about null values in relational databases. The relational model was defined in 1969, and Nulls Was died in 1979. Unfortunately, there is not a generally agreeable solution for rull values problem. Null is a special marker which stands for a value undefined or unknown, which means thut ne entry has been made, a missing valuc mark is not a value and not of a date type and cannot be treated as a value by Database Management System (DBMS). As we know, distributed database users are more than a single database and data will be distributed among several data sources or sites, it must be precise data, the replication is allowed there, so complex problems will appear, then there will be need for perfect practical general approaches for treatment of Nulls. A distributed database system is designed, that is "Hotel reservation control system, based on different data sources at four site, each site is represented as a Hotel, for more heterogeneity different application programming languages there are five practical approaches, designed with their rules and algorithms for Null values treatment through the distributed database sites.

Authors: Shiltagh Nadia , Faisal Zainab
Published: April 2020

Wireless Sensor Networks (WSNs) are event-driven network systems consist of many sensors node which aredensely deployed and wirelessly interconnected that allow retrieving of monitoring data. In Wireless sensor network,whenever an event is detected, the data related to the event need to be sent to the sink node (data collection node). Sink nodeis the bottleneck of network there may be chance for congestion due to heavy data traffic. Due to congestion, it leads to dataloss; it may be important data also. To achieve this objective, soft computing based on Neural Networks (NNs) CongestionController approach is proposed. The NN is activated using wavelet activation function that is used to control the traffic ofthe WSN. The proposed approach which is called as Modified Neural Network Wavelet Congestion Control (MNNWCC), hasthree main activities: the first one is detecting the congestion as congestion level indications; the second one is estimated thetraffic rate that the upstream traffic rate is adjusted to avoid congestion in next time, the last activates of the proposedapproach is improved the Quality of Services (QoS), by enhancement the Packet Loss Ratio (PLR), Throughput (TP), BufferUtilization (BU) and Network Energy (NE) . The simulation results show that the proposed approach can avoid the networkcongestion and improve the QoS of network.
Network Coded Modulation for Two Way Relay Networks
Authors: Kadhim Abdulkareem , Ali Karrar
Published: April 2020

Modern wireless networks use cooperative relaying to expand its coverage area. Wireless relaying allows mobile terminals toparticipate in transmission even when these terminals are not being the initial source or final destination. This can be achieved in differentways ranging from simple conventional relaying to more sophisticated coding at terminal and relay nodes to improve transmissionperformance. The proposed work here studied such system by simulating different coding techniques to be used in two way relay networkcoding (TWRC). Some of these techniques were previously proposed to improve transmission performance in conventional datacommunication systems. BER performance of different arrangements of coding and relaying schemes are evaluated using computersimulation tests. Ideal AWGN channel model and standard wireless channel models for wireless networks are considered in the simulationtests. The results have been shown that coding schemes such as Trellis Coded Modulation (TCM) and Repeat Accumulate (RA) codes aremore suitable in two way relaying networks. Over AWGN, TCM-8PSK improves BER performance by at least 2 dB at high SNR fordifferent relaying arrangements. For fading channels, this advantage is slightly reduced. Regenerative repeating at relay node seems to be apromising arrangement. It seems that there is no sense in using RA codes over fading channels due to its poor performance and relativelylower speed caused by repetitions.

Published: April 2020

In order to develop a specific methodology that can be followed by any organization or individual who needs tochoose the appropriate E-Forms application that could meet the required needs, this research proposes a methodology whichconsists of three phases: Identification phase, Evaluation phase and Testing phase. In the first phase, a general survey on EFormstypesandtechnologiesisintroducedwithfocusontherecenttrendsinorder

to identify which type mostly meets theuser's general requirements. In the second phase, an evaluation to make an accurate selection is made to some of the topcompeting applications supporting the type identified in first phase by using a specific evaluation methodology, in thisresearch three of the widely used evaluation methodologies are discussed, in addition to a simple evaluation methodologywhich has been proposed and implemented using "Microsoft Excel Sheets" application. Finally in the third phase, a real test ismade using the winner application resulting from the second phase, where a four-stage testing plan is proposed in order toachieve this purpose. As an example, the E-Forms technology which is based on "Extensible Markup Language (XML)" isidentified due to its features and capabilities. Then the evaluation is made to the top applications supporting this technology,where "Adobe's XML Forms Architecture (XFA)" technology is selected as a winner. This winner application then is tested,where samples of forms were designed to show the extraordinary features this technology can offer including digital signature.The test includes the use of a proposed offline forms' data gathering technique and uses "Oracle 10g" as the back-enddatabase. It also includes a website to publish the designed forms in addition to an application developed using "OracleDeveloper 10g" to process the forms' data for one of the designed samples in order to prove these forms' accuracy.

Authors: Jumaa Bassim , Naser Ayad , Khalaf Maryam
Published: April 2020

Character Recognition is the text recognition system that allows hard copies of written or printed text to be renderedinto editable, soft copy versions. In this paper, work has been performed to recognize pattern using multilayer perceptronlearning by Artificial Bee algorithm (ABC) that simulates the intelligent foraging behavior of a honey bee swarm. MultilayerPerceptron (MLP) trained with the standard back propagation (BP) algorithm normally utilizes computationally intensivetraining algorithms. One of the crucial problems with the BP algorithm is that it can sometimes yield the networks withsuboptimal weights because of the presence of many local optima in the solutions space. The suggested method is to use ABC forlearn the Neural Networks, to solve text character recognition problem, by update the Neural Networks weights. A comparisonstudies are made between ABC and BP methods in NN learning to specify which is better in solving character recognitionproblem.

The stego audio isperceptually indistinguishable from the equivalent cover audio. The proposed method allows hiding a sameduration of speech (secret) and audio (cover). The stego audio is subjected to objective tests such signal to noiseratio (SNR), signal to noise ratio segmental (SNRseg), Segmental Spectral SNR, Log Likelihood Ratio (LLR)and Correlation (Rxy) to determine the similarity with original audio.

Authors: Al-Bakry Abbas , Al-Rikaby Marwa
Published: April 2020

Levenshtein is a Minimum Edit Distance method; it is usually used in spell checking applications for generatingcandidates. The method computes the number of the required edit operations to transform one string to another and it canrecognize three types of edit operations: deletion, insertion, and substitution of one letter. Damerau modified the Levenshteinmethod to consider another type of edit operations, the transposition of two adjacent letters, in addition to theconsidered three types. However, the modification suffers from the time complexity which was added to the original quadratictime complexity of the original method. In this paper, we proposed a modification for the original Levenshtein toconsider the same four types using very small number of matching operations which resulted in a shorter execution timeand a similarity measure is also achieved to exploit the resulted distance from any Edit Distance method for finding the amountof similarity between two given strings.

Proposed Method to Prevent SQL Injection Attack
Authors: Aziz Makera , Ahmed Dena
Published: April 2020

the internet and its websites have huge using these days. These webs may have sensitive and secret information likemilitary information, financial information and other important information that transfer through the networks.Only some people have the authorization to see and access this information. So information has to transfer in secretenvironment. SQL injection represents one of the most important things that thread these webs. In which unauthorizedpeople can access to the data and information. This paper introduces a method that can be used to prevent SQL injectionby converting the user input to static string, use this string as user input and compared with the database attributes that needto compare with, during the runtime. The goal behind converting the input to a string is to make user input as a singleunit (one token) that cannot use as a SQL query statement. The system will call the database attribute in such away in whichuser cannot access to the sql statement to do the injection. And the sql query will be empty from any input tools that can use byuser to injects the SQL.

Corners-based Image Information Hiding Method
Authors: Talib Ahmed
Published: April 2020

The huge explosion of information over World Wide Web forces us to use information security methods to keep it away fromintruders. One of these security methods is information hiding method. Advantage of this method over other security methods is hidingexistence of data using carrier to hold this data embedding inside it. Image-based information hiding represents one of widely usedhiding methods due to the image capability of holding large amount of data as well as its resistance to detectable distortion. In lastdecades, statistical methods (types of stego-analysis methods) are used to detect existing of hidden data. Therefore, areas that have colorvariation (edges area) are used to hide data instead of smooth areas. In this paper, Corners points are proposed to hide data instead ofedges, this to avoid statistical attacks that are used to expose hidden message. Additionally, this paper proposes clearing least significantbit (CLSB) method to retrieve data from stego-image without sending pixels' map; this will increase security of the proposed cornerbasedhiding method. Experimental results show that the proposed method is robust against statistical attacks compared with edge-and sequential-based hiding methods. SVM classifier also confirms the outperformance of the proposed method over the previous methods by using Corel-1000image dataset.

Immersive virtual reality isn’t just for gaming. It’s poised to have a big impact on education as well, giving students an opportunity to interact with content in three-dimensional learning environments. Blended learning, according to the Inn sight Institute is "a formal education program in which a student learns at least inpart through online delivery of content and instruction with some element of student' control over time, place, path and/orpace". On the other hand, there are many disadvantage found in blended learning such as the learners with low motivation or bad study habits may fall behind, and many others. So, there is an essential need to improve and develop the theory of the blended learning by using virtual reality environments and get rid of these disadvantages to develop the faceto-face learning to add a lot of features such as excitement and make it more efficient. As well as affirms clarity of the scientific content of the lecture that the student may be miss them by absent or even mentally, so student can live atmosphere the lecture again and overcome the difficulties resulting from the using blended learning or traditional learning. Firstly, this approach is applied by building a specialized website application that allow using virtual reality feature in order to measure the effectiveness of this study on students, and then a questionnaires was designed and the information result of these questionnaires impact was gathered. It is found that, the most of students were excited, active and they understand the lecture in an easy way with a high Likert Scale (4.74), but they found difficulties in using VR tools which has a low Likert scale (2.66).

Published: April 2020

Information security is a huge trending topic in recent year. Many technique and algorithm were designed and developed toachieve the security of information and/or network across the world. Cryptography is one of the most common tools to provide suchsecurity. Nevertheless, steganography also provide a good security by hiding data within a media in a way that an attacker can't sensethe presence of the secret data. Compression don't normally imply any security , however , it messes up the original encoding of the dataand reduces its size by a measureable amount which makes it perfect for hiding .In this paper a system was proposed where a secretimage is compressed before encryption and hiding. JPEG algorithm was used for the compressing, while at the encryption stage RC4algorithm was used due to its fast processing speed. LSB (Least Significant Bit) technique then applied to hide the secret data within thecover image.

Published: April 2020

In this paper, a secure chatting application with end to end encryption for smart phones that used the android OS has beenproposed. This is achieved by the use of public key cryptography techniques. The proposed application used the Elliptic Curve DiffieHellman Key Exchange (ECDH) algorithm to generate the key pair and exchange to produce the shared key that will be used for theencryption of data by symmetric algorithms. The proposed Application allows the users to communicate via text messages, voicemessages and photos. For the text message security the standard AES algorithm with a 128 bit key are used. The generated key (160 bit)minimized to 128 bit length by selecting the first 128 bit of the generated key in order to be used by the AES algorithm. For the voice andimage security processes the proposed application used the symmetric algorithm RC4 for this purpose.
Compression image sharing using DCT- Wavelet transform and coding by Blackely method
Authors: Ahmed Ali , George Loay
Published: April 2020

The increased use of computer and internet had been related to the wide use of multimedia information. The requirement forprotecting this information has risen dramatically. To prevent the confidential information from being tampered with, one needs toapply some cryptographic techniques. Most of cryptographic strategies have one similar weak point that is the information is centralized.To overcome this drawback the secret sharing was introduced. It’s a technique to distribute a secret among a group of members, suchthat every member owns a share of the secret; but only a particular combination of shares could reveal the secret. Individual sharesreveal nothing about the secret. The major challenge faces image secret sharing is the shadow size; that's the complete size of the lowestneeded of shares for revealing is greater than the original secret file. So the core of this work is to use different transform codingstrategies in order to get as much as possible the smallest share size. In this paper Compressive Sharing System for Images UsingTransform Coding and Blackely Method based on transform coding illustration are introduced. The introduced compressive secretsharing scheme using an appropriate transform (Discrete cosine transform and Wavelet) are applied to de-correlate the image samples,then feeding the output (i.e., compressed image data) to the diffusion scheme which is applied to remove any statistical redundancy orbits of important attribute that will exist within the compressed stream and in the last the (k, n) threshold secret sharing scheme, where nis the number of generated shares and k is the minimum needed shares for revealing. For making a certain high security level, eachproduced share is passed through stream ciphering depends on an individual encryption key belongs to the shareholder.
