The challenge in this task comes from the restrictions imposed, like, computational resources, available power, limited space, and limited budget. Usually INS / GNSS integration is utilized for that purpose, but for an INS to be applicable for that task it is required to be high-end INS, which will require more space, and will be over budget, in addition to export restrictions which makes high-end IMU not a valid solution. So, this paper assesses the ability to determine two of the three required attitudes (pitch and heading) in the navigation states using only GNSS system, without incorporating any other external sensor. A data for two high-speed projectile scenarios were generated using IMUS (GNSS and Inertial Simulator) Software, each scenario was repeated multiple times with different GNSS accuracy. Then the attitude mathematical algorithm was implemented on MATLAB for evaluation and assessments of the experiments. Results revealed the ability of the proposed approach to estimate the pitch and heading angle using GNSS system only with acceptable accuracy for different scenarios including various GNSS data rates and position uncertainties as well.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121839297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional techniques in this research area have mainly focused either on the simplified single-label case or on pixel-based approaches, which cannot efficiently handle high-resolution images. Deep learning (DL) and convolutional neural networks (CNNs) have defined the state-of-the-art in many vision problems in recent years. CNNs often adopt pooling layers to enlarge the receptive field, which can lower computational complexity. On the other hand, Conventional pooling methods can result in data loss, degrading subsequent operations such as feature extraction, image retrieval, and scene analysis. Inspired by this drawback, we propose a new CNN model by investigating the impact of discrete wavelet transform pooling (DWTPL) on the performance of this model. Wavelet pooling allows us to utilize spectral information, which is crucial in multi-label remote sensing tasks. We show consistent improvements in precision and F1-score on a widely adopted AID dataset compared to other models from the recent literature.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122221909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate detection of breathing is critical in the research of regular respiratory of the athletes, detection of drug addicts, and detection of the blood nitrogen ratio of divers and many other areas. Technically this process is difficult due to changes in breathing and other factors. This paper presents and proposes a strategy to design a quantitative respiratory gas analyzer with sensors based on microcontrollers through a fuzzy logic model. The proposed system uses five sensors that will detect different gases such as methane, alcohol, natural gas, carbon monoxide, and hydrogen. These sensors detect the concentration of gases. If the gas concentration is above the permissible exposure limit (PEL), the predefined user will be notified of the gas leak situation. Five groups were formed, each group consists of 40 people so that each group is exposed daily to a type of gases measured by the designed and implemented device. The design is implemented using a microcontroller (ATmega328P); for its lower cost and high efficiency. In our research, the main goal is to obtain the highest-level result in determining the amount of gas in the blood by breathing. Generally, accurate detection of breathing is critical in the search for the regular respiratory system of athletes, drivers, and aviation personnel who are constantly exposed to the gas. This research contributes to providing a low-cost, high-quality portable measurement system and using a new strategy to measure the proportion of gases measured in the blood and to determine an initial diagnosis using the fuzzy logic model. This portable system can be used in homes, hospitals, and tests for drivers, nurses, and pilots.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130049962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computer worms are used to conduct cyberattacks to compromise computers and the data stored on them. The self-propagation characteristic of computer worms allows them to spread fast and infect many hosts in a computer network. Thus, this makes it difficult for humans to deploy a timely countermeasure to confront worm infections within the attacked network. Worm containment is utilized to stop worm spread in a computer network. The containment technique should be automatic, timely, reliable, and implemented in a distributed manner. In this paper, we introduce Rearguard, a novel blockchain-based automatic worm containment system. Rearguard achieves worm containment by creating and distributing vulnerability-based filters for the vulnerabilities being exploited. A vulnerability-based filter is employed to drop any received network message contains variants of a worm that attempts to exploit the same vulnerability. The vulnerability-based filter generation is carried out utilizing a blockchain smart contract deployed in the attacked network. The blockchain ensures reliability, timely response, trustworthy filters, and the availability of all filters in a distributed ledger that is maintained by network hosts. Rearguard has been implemented against a synthetic worm. The obtained results show that Rearguard introduces low overhead as well as ensures timely and automatic response to worm attacks.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134209736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have been deployed in many applications such as radar, remote sensing, and satellite applications. Furthermore, such guided wave structures have various advantages in a term of the strength of the structure, high power handling capability, efficiency, and small dimensions which make them more appealing to be employed in microwave frequency range applications. In this paper, design, analysis and comparison of structures for radar applications with enhanced performance using impedance matching, has been obtained. The $TE_{10}$ transmission enhancement obtained through two varieties, the first variety is the feeder with straight output ports and the second is the feeder with V-output ports for V-antenna applications. The enhancement transmission ratio (ETR) is the ratio of transmission of both structures with and without stub. Structures have been analyzed using HFSS and CST. The proposed structures presents ETR for TE10 up to 17.7 and 28.8 at 11.43 and 8.12 GHz for both varieties respectively compared to the conventional feeders without stubs using HFSS simulator. The same structures present ETR for TE10 up to 17.6 and 28.7 at 11.93 and 8.63 GHz using CST simulator. The proposed structures characteristics such as the magnitude of transmission coefficient, log scale distribution of current on surface and the ETR are obtained to demonstrate the performance of structures using HFSS and CST simulators.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131249277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Left-handed (LH) materials provide unique new properties when compared to traditional right-handed (RH) materials because they have negative permittivity and permeability at the same time. A Composite Right/Left-Handed (CRLH) transmission line (TL) structure comprised of a series inter-digital capacitor and a shunt inductor is used to implement the left-handed properties. This paper thoroughly examines the CRLH TL theory. The verification is carried out using a commercial software package. The observed simulation results agreed well with the theoretical prediction. A zeroth-order resonator (ZOR) CRLH antenna's resonate frequency is independent of its physical length, which is a unique feature. This allows to produce small, compact antennas. The ZOR CRLH antennas are designed, simulated, fabricated, and tested at low frequencies. The ZOR CRLH antenna is constructed in a systematic manner. To demonstrate the antenna performance, the radiation characteristics of the ZOR antenna are shown. The antenna laboratory's network analyzer was used to fabricate and measure the final design structures. For LTE and wireless communication applications, the measured and simulated results provide excellent performance.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115849494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
