It covers the 5G proposed (additional) band, i.e., 31.8-33.4 GHz. 5G is much concerned with fast speeds in signal and data transmission as well as higher spectral efficiencies. The MIMO antenna system can improve the capacity and transmission rates in a communication system. The design with the help of simulation is quite important in visualization of the desired output and helps in achieving the required antenna results. Simulation results help in analysis of some parameters such as return loss and antenna isolation, to check the performance requirements of the designed system. According to the simulation results, the isolation is 17 dB between the antennas throughout the frequency band of 31.8-33.4 GHz, it will meet the requirements of future generation.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127323530","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}

Abbas","doi":"10.1109/CEET1.2019.8711834","DOIUrl":"https://doi.org/10.1109/CEET1.2019.8711834","url":null,"abstract":"The Internet of Things (IoT) regulates millions of terabytes of data for everyday commercial, industrial, technical and personal usage. Considered as the greatest technological revolution, all IoT-based transformations are now occurring to increase productivity and create a coordinated world across business and technologies. However, the exchange, storage, processing and transfer of tremendous amounts of sensitive information has also given rise to severe security and privacy concerns that compromise the efficiency and usability of IoT. It has become a challenge for users to depend on such a vulnerable technology, where the IoT security risks outweigh its benefits. Several defense techniques, algorithms and solution models have been proposed and implemented to counter these attacks. However, there are limitations involved as robust incursions make these solutions obsolete. It is vital to have an overview of the research done and find loopholes to fill in the security gaps to ensure a safe IoT ecosystem. Realizing the need of enhanced problem-solving strategies, this paper provides a systematic review of the existing strategies for IoT security and privacy, and provides an analytical approach in identifying the concerns and solutions. It discusses IoT architecture, classifies the various domains of security and privacy and presents a taxonomy and a comparative analysis to outline the security goals, threats and attacks, and solutions proposed in recent years (2015–2018). Our research methodology comprises of thorough qualitative analyses and a literature review to help evaluate the questions asked in this survey. We also highlight the limitations of the previous studies and the open issues. Our survey results focus on the problems that require further attention to improve the IoT progression.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127292395","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}

To integrate low renewable voltage with high voltage DC microgrid, a high gain DC converter is essential. Moreover, to enhance efficiency and reduce the cost, multiport converters play a pivotal role. Various topologies proposed in the literature achieve only low voltage gains from source to load. This paper presents a DC converter that achieves both a high gain output as well as multiport operation. The converter also integrates a storage device (battery) with renewable resource to provide backup in the absence of renewable energy. Bidirectional voltage flow is achieved through buck operation for battery charging. The proposed topology presents a four port converter with a voltage source, battery and asymmetric bipolar outputs, suitable for interfacing with DC microgrid and hybrid electric vehicles. Two inductors are used in the topology to achieve high voltage gain. Circuit operation, simulation, voltage gain and efficiencies are critically analyzed. Operation, design consideration and simulations at different levels of the proposed structure are presented.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128738433","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}

OpenStack's networking module i.e. Neutron provides a centralized routing service, where L3 packets are redirected to a central network node. A single network node is incapable of handling overlapping IP addresses for multiple networks, which in turn, greatly decreases network bandwidth and throughput of production environments. This paper introduces two technologies that can alleviate the network performance issues as faced by Neutron. Furthermore, these two technologies namely OpenDaylight (ODL) and Distributed Virtual Routing (DVR) are then presented together with a set of benchmarks which showcase their performance in a production environment. The performance results show ODL and DVR out perform Neutron in every layer 3 case, making them as an upgrade for any traditional OpenStack based environment.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124333287","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}

It is very rough assignment for humans to manually explain the central subject from the large article. De- Summarization can be separating into two branches as Abstractive and Extractive approaches. Extractive accumulates the imperative paragraph or sentence from the original document and presents them as an explanation. Urdu inherits a lot of vocabulary from Arabic, Persian and the native languages of South Asia. Due to this effect, Urdu has a complex morphology. In terms of syntax, it has a relatively free word order (Subject, Object, and Verb). Despite spoken by millions of people, Urdu is an under-resourced language in terms of available computational resources. We extent the single document extractive de-summarization methodology for Urdu based on the sentence weight algorithm especially for the news, sports, and health etc. topics. We encapsulate the manuscript by preprocessing (sentence segmentation, tokenization, stop words and lemmatization) and apply sentence weight algorithm.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114998083","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}

These are being used for industrial as well as for military purposes. Most of the existing unmanned aerial vehicles are fixed wing and carry missiles and bombs hence they cannot be used for point defence. Hover capability is required for point defence which is an attribute of rotorcrafts. The rotorcraft with a gun mount with point defence capability is currently available which was developed by US Air Force. Pakistan has combat drones which are fixed wing so there is need of developing combat drones with rotorcrafts. The aim of this project is to develop an anti-terrorist unmanned aerial vehicle that can perform surveillance and reconnaissance with weapon launch system that will be installed on it to provide point defence. A brief history of usage of UAVs is discussed followed by different structural components that are used in assembly of UAV. The combat drone systems that are being used currently have been discussed along with some proposed modifications and improvements for better performance and increased efficiency.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116943308","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}

However, most renewable sources are intermittent in nature and generate a lower level voltage than is required by most applications to operate. Hence, a DC-converter becomes essential to boost the lower level voltage to a higher application level voltage. Moreover, a battery port becomes mandatory for backup storage application for load support. Multi-Port Converter (MPC) can integrate both the converter and the battery port within a single structure. This paper proposes a novel DC-DC MPC with a backup battery port. The proposed converter supports five ports including three renewable inputs, one battery and a single output port. The port is designed to support the grid and will generate an output voltage of 400 V. A PIC control-based scheme is also implemented for the proposed converter to make the outputs stabilized for fluctuating input voltage.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130798988","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}

With the increased emphasis on energy conservation in buildings, educational institutions have started Energy management programs to reduce the energy demand in order to cut the energy expenses. This paper presents a critical analysis on the base of Energy Audit conducted in University of Engineering and Technology Taxila aimed to analyze the demand pattern and the prospects of improvements in the current electrical system. The paper present the details regarding the saving potential possible through retrofitting of energy-guzzling loads with improved and efficient ones. The data collected is analyzed using DIALux for the lighting loads and Hourly Analysis Program (HAP) for heating and cooling systems. An estimated load reduction of 63.02% can be achieved per day by retrofitting old lighting load with a newer one. This energy consumption saving accounts up to 2907 kWh per day including utilization factor. An estimated reduction of 25.01% is achieved per day by the replacement of old Air-Cooling and Air-conditioning appliances with the new ones with the energy consumption saving up to 2336.48 kWh per day including utilization factor. The net payback period for retrofitting is calculated to be 1.95 years for lighting and 6.30 years for air-cooling and air-conditioning load. In order to take one step forward towards a sustainable campus, the solar potential and feasibility of the campus are calculated. The peak rooftop solar potential is calculated to be 2.81 MW with expected annual generation around 4,434,000kWh. PV System software is used to carry out the solar potential results. Energy Audit methodology alongside cost estimation for the suggested improvements in appliances, payback periods, and solar harvesting potential is calculated in the paper. The recommended improvements will help us in energy conservation and achievement of a sustainable campus.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128777430","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}

Chaotic behavior can be explained by both autonomous and non autonomous circuits. The operation of non-autonomous circuits has usually exchanged physical simplification of the circuit for mathematically complex analysis, or vice versa. So, autonomous circuits are preferred from practical standpoint. In this paper, a simple autonomous circuit is presented with robust chaotic behavior. This circuit minimizes both physical and model component counts offering simple analysis. Nonlinear dynamical behavior of the proposed circuit will be explored towards fixed point attractor. Circuit simulation will be done on Multisim software as well as experimental analysis will also be performed for exploring the nonlinear behavior of the circuit.","PeriodicalId":207523,"journal":{"name":"2019 International Conference on Engineering and Emerging Technologies (ICEET)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126688899","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}
