The antenna is composed of a pair of CSRRs etched on the ground plane and excited by an open-ended microstrip line feed symmetrically placed between the two CSRRs at the upper substrate side. To enhance the inherently CSRRs limited bandwidth; two rectangular slots are introduced in the vicinity of each CSRR resulting in a significant bandwidth improvement and also in lowering the operating frequency. The resonance frequency of the antenna is essentially defined by geometrical parameters of the CSRR, which makes it suitable for a broad range of applications spanning from mobile terminals to WLAN and WPAN systems. The proposed structure has been studied numerically by using CST Microwave studio.","PeriodicalId":272255,"journal":{"name":"2018 6th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121758132","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}

Image registration problem refers to image alignments and it can be defined by linear (rigid) or non-linear transformation. Finding the optimal transformation that aligns two images is a hard optimization problem. In this paper, we propose a recent swarm intelligence algorithm, bare bones fireworks algorithm, for solving rigid image registration problem. The proposed method uses normalized cross-correlation as similarity metrics and it was tested on six benchmark images. Obtained results were compared to other approaches from literature and it has been shown that the proposed technique is better in term of registration accuracy.","PeriodicalId":272255,"journal":{"name":"2018 6th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126440388","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}

Thanks to improvements in computing power, modeling and simulations, using computers, are now used to investigate the dynamics of crowds using agents. This paper proposes a novel agent-based crowd simulation model, using a game engine. Compared to the existing techniques, our proposed model is more flexible and, has the ability to make real-time changes in crowd-modeling. The agent generation method, known as Distinguishable Agents Generating Method (DAGM), are capable of creating 3D animated-humanoid models with distinguished attributes. In this paper, we also propose a Multiple layer Collision System (MCS) that includes a system to collect collision messages and to evaluate the processing. A Building & City-planning Generating System (BCGS) is also introduced to create and setup obstacles in the simulation. This approach can be used for studies, planning and training related to crisis management such as stampede, evacuation, etc. The proposed method is capable of rendering a visually vivid 3D crowd of hundreds of agents using a typical computing environment.","PeriodicalId":272255,"journal":{"name":"2018 6th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115772503","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}

Due to the particularity of metamaterial structure, which could have many uses in upcoming technologies for antennas in mobile communications as their properties could provide new features for user's safety.

Spectrum sensing is the first enabling stage in cognitive radio. The objective is to obtain the state of the band in interest (free/occupied), then use it temporarily without causing any interference to the primary user (PU). It has been shown that the energy detection is the most chosen method to detect the free bands, in the case when there is no prior information about the primary user. In this paper, we are interested in the implementation of the spectrum sensing (SS) operation based on a real FM signal generated by Raspberry pi 3 card using the FHSS method, and captured under MATLAB-Simulink software by an RTL-SDR hardware.
