Signal is one of these instant messaging applications, which makes Signal interesting for digital investigators. In this research, we evaluate the artifacts that are generated by the Signal messenger for Android. This evaluation was done by using the features that Signal provides to create artifacts, whereafter, we made an image of the internal storage and the process memory. This image was analysed manually. The manual analysis revealed the content that Signal stores in different locations during its operation. From our research, we were able to identify the artifacts and interpret how they were used. We also examined the source code of Signal. Using our obtain knowledge from the source code, we developed a tool that decrypts some of the artifacts using the key stored in the Android Keystore. In general, we found that most artifacts are encrypted and encoded, even after decrypting some of the artifacts. During data visualization, some artifacts were found, such as that Signal does not use relationships between the data. In this research, two interesting groups of artifacts were identified, those related to the database and those stored in the process memory dump. In the database, we found plaintext private- and group chats, and in the memory dump, we were able to retrieve the plaintext access code to the application. Nevertheless, we conclude that Signal contains a wealth of artifacts that could be very valuable to a digital forensic investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic" title="forensic">forensic</a>, <a href="https://publications.waset.org/abstracts/search?q=signal" title=" signal"> signal</a>, <a href="https://publications.waset.org/abstracts/search?q=Android" title=" Android"> Android</a>, <a href="https://publications.waset.org/abstracts/search?q=digital" title=" digital"> digital</a> </p> <a href="https://publications.waset.org/abstracts/145060/forensic-analysis-of-signal-messenger-on-android" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145060.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18580</span> A General Framework to Successfully Operate the Digital Transformation Process in the Post-COVID Era</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Driss%20Kettani">Driss Kettani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we shed light on “Digital Divide 2.0,” which we see as COVID-19’s Version of the Digital Divide!

Because the output of digital sensors cannot be simply monitored by a measuring instrument such as an oscilloscope, students tend to have a hard time dealing with digital sensors. The monitoring program runs on a PC and communicates with an MCU that reads the output of digital sensors via an asynchronous communication interface. Receiving the sensor data from the MCU, the monitoring program shows time and/or frequency domain plots of the data in real time. In addition, the monitoring program provides a serial terminal that enables the user to exchange text information with the MCU while the received data is plotted. The user can easily observe the output of digital sensors and configure the digital sensors in real time, which helps students who do not have enough experiences with digital sensors. Though the monitoring program was programmed in the Matlab programming language, it runs without the Matlab since it was compiled as a standalone executable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20sensor" title="digital sensor">digital sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title=" MATLAB"> MATLAB</a>, <a href="https://publications.waset.org/abstracts/search?q=MCU" title=" MCU"> MCU</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20monitoring%20program" title=" signal monitoring program"> signal monitoring program</a> </p> <a href="https://publications.waset.org/abstracts/41706/development-of-a-serial-signal-monitoring-program-for-educational-purposes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41706.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">496</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18578</span> Speech Enhancement Using Kalman Filter in Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eng.%20Alaa%20K.%20Satti%20Salih">Eng.

The important application is the speech enhancement, which is done to remove suppressed noises and echoes taken by a microphone, beside preferred speech. Accordingly, the microphone signal has to be cleaned using digital signal processing DSP tools before it is played out, transmitted, or stored. Engineers have so far tried different approaches to improving the speech by get back the desired speech signal from the noisy observations. Especially Mobile communication, so in this paper will do reconstruction of the speech signal, observed in additive background noise, using the Kalman filter technique to estimate the parameters of the Autoregressive Process (AR) in the state space model and the output speech signal obtained by the MATLAB.

The circuit generates a signal, the logical value of which depends on the process corner only. The signal can be used in both digital and analog circuits for testing and compensation of process variations (PV). The presented circuit uses only metal-oxide-semiconductor (MOS) transistors, which allow increasing its detection accuracy, decrease power consumption and area. Due to its simplicity the presented circuit can be easily modified to monitor parametrical variations of only n-type and p-type MOS (NMOS and PMOS, respectively) transistors, resistors, as well as their combinations. Post-layout simulation results prove correct functionality of the proposed circuit, i.e. ability to monitor the process corner (equivalently die-to-die variations) even in the presence of within-die variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=detection" title="detection">detection</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20corner" title=" process corner"> process corner</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20variation" title=" process variation"> process variation</a> </p> <a href="https://publications.waset.org/abstracts/65067/metal-oxide-semiconductor-only-process-corner-monitoring-circuit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65067.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">525</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18576</span> An Ultrasonic Signal Processing System for Tomographic Imaging of Reinforced Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Forero-Garcia">Edwin Forero-Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Vitola"> Jaime Vitola</a>, <a href="https://publications.waset.org/abstracts/search?q=Brayan%20Cardenas"> Brayan Cardenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Casagua"> Johan Casagua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research article presents the integration of electronic and computer systems, which developed an ultrasonic signal processing system that performs the capture, adaptation, and analog-digital conversion to later carry out its processing and visualization. The capture and adaptation of the signal were carried out from the design and implementation of an analog electronic system distributed in stages: 1. Coupling of impedances; 2. Analog filter; 3. Signal amplifier. After the signal conditioning was carried out, the ultrasonic information was digitized using a digital microcontroller to carry out its respective processing. The digital processing of the signals was carried out in MATLAB software for the elaboration of A-Scan, B and D-Scan types of ultrasonic images. Then, advanced processing was performed using the SAFT technique to improve the resolution of the Scan-B-type images. Thus, the information from the ultrasonic images was displayed in a user interface developed in .Net with Visual Studio. For the validation of the system, ultrasonic signals were acquired, and in this way, the non-invasive inspection of the structures was carried out and thus able to identify the existing pathologies in them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acquisition" title="acquisition">acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=SAFT" title=" SAFT"> SAFT</a>, <a href="https://publications.waset.org/abstracts/search?q=HMI" title=" HMI"> HMI</a> </p> <a href="https://publications.waset.org/abstracts/162674/an-ultrasonic-signal-processing-system-for-tomographic-imaging-of-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162674.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18575</span> The Role of Business Process Management in Driving Digital Transformation: Insurance Company Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Su%C5%A1a%20Vugec">Dalia Suša Vugec</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana-Marija%20Stjepi%C4%87"> Ana-Marija Stjepić</a>, <a href="https://publications.waset.org/abstracts/search?q=Darija%20Ivandi%C4%87%20Vidovi%C4%87"> Darija Ivandić Vidović</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital transformation is one of the latest trends on the global market. In order to maintain the competitive advantage and sustainability, increasing number of organizations are conducting digital transformation processes. Those organizations are changing their business processes and creating new business models with the help of digital technologies. In that sense, one should also observe the role of business process management (BPM) and its maturity in driving digital transformation. Therefore, the goal of this paper is to investigate the role of BPM in digital transformation process within one organization. Since experiences from practice show that organizations from financial sector could be observed as leaders in digital transformation, an insurance company has been selected to participate in the study. That company has been selected due to the high level of its BPM maturity and the fact that it has previously been through a digital transformation process. In order to fulfill the goals of the paper, several interviews, as well as questionnaires, have been conducted within the selected company. The results are presented in a form of a case study. Results indicate that digital transformation process within the observed company has been successful, with special focus on the development of digital strategy, BPM and change management. The role of BPM in the digital transformation of the observed company is further discussed in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process%20management" title="business process management">business process management</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study" title=" case study"> case study</a>, <a href="https://publications.waset.org/abstracts/search?q=Croatia" title=" Croatia"> Croatia</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=insurance%20company" title=" insurance company"> insurance company</a> </p> <a href="https://publications.waset.org/abstracts/96874/the-role-of-business-process-management-in-driving-digital-transformation-insurance-company-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18574</span> Detection of Clipped Fragments in Speech Signals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergei%20Aleinik">Sergei Aleinik</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Matveev"> Yuri Matveev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a novel method for the detection of clipping in speech signals is described.

We show also that the Alamouti scheme is the most sensitive MIMO scheme to CFO. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modulation%20and%20multiplexing%20%28MIMO-OFDM%29" title="modulation and multiplexing (MIMO-OFDM)">modulation and multiplexing (MIMO-OFDM)</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing%20for%20transmission%0D%0Acarrier%20frequency%20offset" title=" signal processing for transmission carrier frequency offset"> signal processing for transmission carrier frequency offset</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20digital%20TV" title=" future digital TV"> future digital TV</a>, <a href="https://publications.waset.org/abstracts/search?q=imaging%20and%20signal%20processing" title=" imaging and signal processing"> imaging and signal processing</a> </p> <a href="https://publications.waset.org/abstracts/22713/robustness-of-mimo-ofdm-schemes-for-future-digital-tv-to-carrier-frequency-offset" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22713.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">487</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18572</span> Effect of Enterprise Digital Transformation on Enterprise Growth: Theoretical Logic and Chinese Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bin%20Li">Bin Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the era of the digital economy, digital transformation has gradually become a strategic choice for enterprise development, but there is a relative lack of systematic research from the perspective of enterprise growth. Based on the sample of Chinese A-share listed companies from 2011 to 2021, this paper constructs A digital transformation index system and an enterprise growth composite index to empirically test the impact of enterprise digital transformation on enterprise growth and its mechanism. The results show that digital transformation can significantly promote corporate growth. The mechanism analysis finds that reducing operating costs, optimizing human capital structure, promoting R&D output and improving digital innovation capability play an important intermediary role in the process of digital transformation promoting corporate growth. At the same time, the level of external digital infrastructure and the strength of organizational resilience play a positive moderating role in the process of corporate digital transformation promoting corporate growth. In addition, while further analyzing the heterogeneity of enterprises, this paper further deepens the analysis of the driving factors and digital technology support of digital transformation, as well as the three dimensions of enterprise growth, thus deepening the research depth of enterprise digital transformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title="digital transformation">digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=enterprise%20growth" title=" enterprise growth"> enterprise growth</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20technology" title=" digital technology"> digital technology</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20infrastructure" title=" digital infrastructure"> digital infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=organization%20resilience" title=" organization resilience"> organization resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20innovation" title=" digital innovation"> digital innovation</a> </p> <a href="https://publications.waset.org/abstracts/181633/effect-of-enterprise-digital-transformation-on-enterprise-growth-theoretical-logic-and-chinese-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181633.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18571</span> Managing Business Processes in the Age of Digital Transformation: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana-Marija%20Stjepi%C4%87">Ana-Marija Stjepić</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Su%C5%A1a%20Vugec"> Dalia Suša Vugec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, digital transformation is one of the leading topics that occupy the attention of scientific circles and business experts. Organizational success is most often reflected through the successful managing of business processes. Given the growing market for digital innovations and its ever-increasing impact on business, organizations need to be prepared for organizational changes that come with the digital era. In order to maintain their competitive advantage in the global market, organizations must adapt their processes to new digitalization conditions. The main goal of this study is to point out the link between the digital transformation and the business process management concept. Therefore, in order to contribute to the scientific field that explores the potential relation between business process management concept and digital transformation, a literature review has been conducted. Papers have been searched within the Business Process Management Journal by keywords related to the term digital transformation. Selected papers have been analyzed according to the topic, type of publication, year of publication, keywords, etc. The results reveal a growing number of papers published on the topic of digital transformation to the Business Process Management Journal, but the lack of case studies. This paper contributes to the extension of academic literature in this important, yet insufficiently researched, scientific field that creates the bond between two strong concepts of digital transformation and business process management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process%20management" title="business process management">business process management</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=digitalization" title=" digitalization"> digitalization</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20change" title=" process change "> process change </a> </p> <a href="https://publications.waset.org/abstracts/108042/managing-business-processes-in-the-age-of-digital-transformation-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108042.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18570</span> Implementation of a Web-Based Wireless ECG Measuring and Recording System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onder%20Yakut">Onder Yakut</a>, <a href="https://publications.waset.org/abstracts/search?q=Serdar%20Solak"> Serdar Solak</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Dogru%20Bolat"> Emine Dogru Bolat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Measuring the Electrocardiogram (ECG) signal is an essential process for the diagnosis of the heart diseases. The ECG signal has the information of the degree of how much the heart performs its functions. In medical diagnosis and treatment systems, Decision Support Systems processing the ECG signal are being developed for the use of clinicians while medical examination. In this study, a modular wireless ECG (WECG) measuring and recording system using a single board computer and e-Health sensor platform is developed. In this designed modular system, after the ECG signal is taken from the body surface by the electrodes first, it is filtered and converted to digital form. Then, it is recorded to the health database using Wi-Fi communication technology. The real time access of the ECG data is provided through the internet utilizing the developed web interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ECG" title="ECG">ECG</a>, <a href="https://publications.waset.org/abstracts/search?q=e-health%20sensor%20shield" title=" e-health sensor shield"> e-health sensor shield</a>, <a href="https://publications.waset.org/abstracts/search?q=Raspberry%20Pi" title=" Raspberry Pi"> Raspberry Pi</a>, <a href="https://publications.waset.org/abstracts/search?q=wiFi%20technology" title=" wiFi technology"> wiFi technology</a> </p> <a href="https://publications.waset.org/abstracts/35188/implementation-of-a-web-based-wireless-ecg-measuring-and-recording-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35188.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18569</span> Anonymous Editing Prevention Technique Using Gradient Method for High-Quality Video</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiwon%20Lee">Jiwon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chanho%20Jung"> Chanho Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Si-Hwan%20Jang"> Si-Hwan Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Ill%20Kim"> Kyung-Ill Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanghyun%20Joo"> Sanghyun Joo</a>, <a href="https://publications.waset.org/abstracts/search?q=Wook-Ho%20Son"> Wook-Ho Son</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the advances in digital imaging technologies have led to development of high quality digital devices, there are a lot of illegal copies of copyrighted video content on the internet.

The proposed scheme is applied spatial and temporal gradient methods to improve the fidelity and detection performance. Also, the scheme duplicates the watermark signal temporally to alleviate the signal reduction caused by geometric and signal-processing distortions. Experimental results show that the proposed scheme achieves better performance than previously proposed schemes and it has high fidelity. The proposed scheme can be used in broadcast monitoring or traitor tracking applications which need fast detection process to prevent illegally recorded video content from spreading out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=editing%20prevention%20technique" title="editing prevention technique">editing prevention technique</a>, <a href="https://publications.waset.org/abstracts/search?q=gradient%20method" title=" gradient method"> gradient method</a>, <a href="https://publications.waset.org/abstracts/search?q=luminance%20change" title=" luminance change"> luminance change</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20watermarking" title=" video watermarking"> video watermarking</a> </p> <a href="https://publications.waset.org/abstracts/42072/anonymous-editing-prevention-technique-using-gradient-method-for-high-quality-video" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">456</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18568</span> A Method to Enhance the Accuracy of Digital Forensic in the Absence of Sufficient Evidence in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Alanazi">Fahad Alanazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Jones"> Andrew Jones</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital forensics seeks to achieve the successful investigation of digital crimes through obtaining acceptable evidence from digital devices that can be presented in a court of law. Thus, the digital forensics investigation is normally performed through a number of phases in order to achieve the required level of accuracy in the investigation processes. Since 1984 there have been a number of models and frameworks developed to support the digital investigation processes. In this paper, we review a number of the investigation processes that have been produced throughout the years and introduce a proposed digital forensic model which is based on the scope of the Saudi Arabia investigation process. The proposed model has been integrated with existing models for the investigation processes and produced a new phase to deal with a situation where there is initially insufficient evidence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20forensics" title="digital forensics">digital forensics</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a>, <a href="https://publications.waset.org/abstracts/search?q=metadata" title=" metadata"> metadata</a>, <a href="https://publications.waset.org/abstracts/search?q=Traceback" title=" Traceback"> Traceback</a>, <a href="https://publications.waset.org/abstracts/search?q=Sauid%20Arabia" title=" Sauid Arabia"> Sauid Arabia</a> </p> <a href="https://publications.waset.org/abstracts/57322/a-method-to-enhance-the-accuracy-of-digital-forensic-in-the-absence-of-sufficient-evidence-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18567</span> Musical Tesla Coil Controlled by an Audio Signal Processed in Matlab</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Cuenca">Sandra Cuenca</a>, <a href="https://publications.waset.org/abstracts/search?q=Danilo%20Santana"> Danilo Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Reyes"> Anderson Reyes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The following project is based on the manipulation of audio signals through the Matlab software, which has an audio signal that is modified, and its resultant obtained through the auxiliary port of the computer is passed through a signal amplifier whose amplified signal is connected to a tesla coil which has a behavior like a vumeter, the flashes at the output of the tesla coil increase and decrease its intensity depending on the audio signal in the computer and also the voltage source from which it is sent.

Reinterpreting the diachroneity of 'intertextuality' in the context of misreading theory extended the range of the 'intermediality' of transmedia to the intense tension between digital images and symbolic images throughout history of images. With the analogy between six categories of revisionary ratios and six steps of digital transformation, digital rhetoric might be illustrated as a linear process reflecting dynamic, intensive relations between digital moving images and original static images. Finally, it was concluded that two-way framework of the rhetoric of transformation of digital images and reversed served as a renarrative structure to revive static images by reconnecting them with digital moving images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhetoric" title="rhetoric">rhetoric</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20art" title=" digital art"> digital art</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediality" title=" intermediality"> intermediality</a>, <a href="https://publications.waset.org/abstracts/search?q=misreading%20theory" title=" misreading theory"> misreading theory</a> </p> <a href="https://publications.waset.org/abstracts/100230/rhetoric-and-renarrative-structure-of-digital-images-in-trans-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18565</span> An Application-Driven Procedure for Optimal Signal Digitization of Automotive-Grade Ultrasonic Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Shawki%20Elamir">Mohamed Shawki Elamir</a>, <a href="https://publications.waset.org/abstracts/search?q=Heinrich%20Gotzig"> Heinrich Gotzig</a>, <a href="https://publications.waset.org/abstracts/search?q=Raoul%20Zoellner"> Raoul Zoellner</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Maeder"> Patrick Maeder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, a methodology is presented for identifying the optimal digitization parameters for the analog signal of ultrasonic sensors.

While new forensics tools require a significant amount of time and effort to be developed and verified, this paper tries to address how to fill this gap using quick-fix alternative methods for digital evidence collection (e.g., based on APIs provided by Apps) and discuss issues related to the admissibility of this evidence to courts with support from international courts’ stance and the circumstances of accepting digital evidence using these proposed alternatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20evidence" title=" digital evidence"> digital evidence</a>, <a href="https://publications.waset.org/abstracts/search?q=laws" title=" laws"> laws</a>, <a href="https://publications.waset.org/abstracts/search?q=investigation" title=" investigation"> investigation</a> </p> <a href="https://publications.waset.org/abstracts/177751/filling-the-gap-of-extraction-of-digital-evidence-from-emerging-platforms-without-forensics-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177751.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18561</span> Heart Murmurs and Heart Sounds Extraction Using an Algorithm Process Separation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Mokeddem">Fatima Mokeddem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The phonocardiogram signal (PCG) is a physiological signal that reflects heart mechanical activity, is a promising tool for curious researchers in this field because it is full of indications and useful information for medical diagnosis. PCG segmentation is a basic step to benefit from this signal. Therefore, this paper presents an algorithm that serves the separation of heart sounds and heart murmurs in case they exist in order to use them in several applications and heart sounds analysis. The separation process presents here is founded on three essential steps filtering, envelope detection, and heart sounds segmentation. The algorithm separates the PCG signal into S1 and S2 and extract cardiac murmurs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phonocardiogram%20signal" title="phonocardiogram signal">phonocardiogram signal</a>, <a href="https://publications.waset.org/abstracts/search?q=filtering" title=" filtering"> filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=Envelope" title=" Envelope"> Envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=Detection" title=" Detection"> Detection</a>, <a href="https://publications.waset.org/abstracts/search?q=murmurs" title=" murmurs"> murmurs</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20sounds" title=" heart sounds"> heart sounds</a> </p> <a href="https://publications.waset.org/abstracts/114970/heart-murmurs-and-heart-sounds-extraction-using-an-algorithm-process-separation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114970.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18560</span> Denoising of Motor Unit Action Potential Based on Tunable Band-Pass Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalida%20S.%20Rijab">Khalida S.

This signal has a noise-like interference pattern resulting from the temporal and spatial summation of action potentials (AP) of all active motor units (MU) near electrode detection. By appropriate processing (Decomposition), the surface EMG signal may be used to give an estimate of motor unit action potential. In this work, a denoising technique is applied to the MUAP signals extracted from the spatial filter (IB2). A set of signals from a non-invasive two-dimensional grid of 16 electrodes from different types of subjects, muscles, and sex are recorded. These signals will acquire noise during recording and detection. A digital fourth order band- pass Butterworth filter is used for denoising, with a tuned band-pass frequency of suitable choice of cutoff frequencies is investigated, with the aim of obtaining a suitable band pass frequency. Results show an improvement of (1-3 dB) in the signal to noise ratio (SNR) have been achieved, relative to the raw spatial filter output signals for all cases that were under investigation. Furthermore, the research’s goal included also estimation and reconstruction of the mean shape of the MUAP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EMG" title="EMG">EMG</a>, <a href="https://publications.waset.org/abstracts/search?q=Motor%20Unit" title=" Motor Unit"> Motor Unit</a>, <a href="https://publications.waset.org/abstracts/search?q=Digital%20Filter" title=" Digital Filter"> Digital Filter</a>, <a href="https://publications.waset.org/abstracts/search?q=Denoising" title=" Denoising"> Denoising</a> </p> <a href="https://publications.waset.org/abstracts/63012/denoising-of-motor-unit-action-potential-based-on-tunable-band-pass-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63012.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">401</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18559</span> Digital Preservation: A Need of Tomorrow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Kumar">Gaurav Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital libraries have been established all over the world to create, maintain and to preserve the digital materials.

This claim is nowadays pushing toward a new circuit design paradigm in which the traditional analog signal processing is expected to be progressively substituted by the processing of times in the digital domain. Within this novel paradigm, digitally controlled delay lines (DCDL) should play the role of digital-to-analog converters in traditional, analog-intensive, circuits. Digital delay locked loops are highly prevalent in integrated systems.The proposed paper addresses the glitches present in delay circuits along with area,power dissipation and signal integrity.The digitally controlled delay lines(DCDL) under study have been designed in a 90 nm CMOS technology 6 layer metal Copper Strained SiGe Low K Dielectric. Simulation and synthesis results show that the novel circuits exhibit no glitches for dual output coarse DCDL with less power dissipation and consumes less area compared to the glitch free NAND based DCDL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glitch%20free" title="glitch free">glitch free</a>, <a href="https://publications.waset.org/abstracts/search?q=NAND-based%20DCDL" title=" NAND-based DCDL"> NAND-based DCDL</a>, <a href="https://publications.waset.org/abstracts/search?q=CMOS" title=" CMOS"> CMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=deep-submicrometer" title=" deep-submicrometer"> deep-submicrometer</a> </p> <a href="https://publications.waset.org/abstracts/2876/low-power-glitch-free-dual-output-coarse-digitally-controlled-delay-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2876.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18557</span> Stakeholder Voices in Digital Evolution: Challenges Faced by SMEs in Automotive Supply Chain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sharaf">Mohammed Sharaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Shokri"> Alireza Shokri</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Small"> Adrian Small</a>, <a href="https://publications.waset.org/abstracts/search?q=Toby%20Bridges"> Toby Bridges</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates digital transformation challenges in SMEs within the automotive supply chain.

If the investigator does not acquire digital proofs in a forensic sound, some important information can be lost, and judges can discard case evidence because the acquisition was inadequate. The correct digital forensic seizing involves preparation of professionals from fields of law, police, and computer science. This paper presents important challenges faced during evidence collection in different perspectives of places.

The competition in Indonesia’s banking industry provides an intriguing case study for understanding how digital transformation can generate innovation in established companies. The empirical evidence of this study is mainly based on interviews and annual reports examining four established banks in their various states of digital transformation. The findings of this study reveal that banks’ digital transformations that lead to innovations differ in terms of the activities undertaken and the outcomes achieved depending on the state of advancement in which they are. Digital transformation is a complex and challenging process, and this study finds that with this strategy, established banks have shown capable of generating innovation. Banks can choose types of transformation activities that generate radical, architectural, modular, or even incremental innovations. <p class="card-text"><strong>Keywords:</strong> <a
