In the near future, the global 5G ubiquitous network strategy that aims at deploying heterogeneous technologies for an internet access, involves also the rural RF deployment. While it is confirmed that 5G would meet stringent requirements in urban zones, rural areas still suffer from almost inexistent MBB (Mobile Broadband) coverage, especially in developing world. To cope with this issue, major insights...
Transforming a city into a Smart Sustainable City (SSC) is a complex, multidimensional process that leads to various changes at all city levels. Different transformation models exist in the literature; each tackles a transformation process from its point of view without a clear justification of the proposed stages and components to be achieved throughout the transformation journey. A solid theoretical...
The aim of this paper is to verify experimentally the constant possibility of performing a Structural Health Monitoring (SHM) in a medium by studying the ambient noise present therein. First, we will illustrate the equivalence between the Green's function and the cross-correlation, then we will move to the experimental studies which will be conducted on a tube. Finally, a comparison algorithm described...
Comfort in social housing constitutes major social and environmental issues for housing tenants, public authorities and social housing managers. For tenants, it means living in an environment offering a minima of security, indoor comfort requirement (temperature, humidity, lighting, acoustic insulation, air quality) and outdoor good conditions (property, common areas, green space, parking) at affordable...
This paper presents the design, realization and use of an innovative system for social housing monitoring. The specifications of the system were determined through concertation with social housing tenants as well as technical and administrative staffs of the social housing manager. The system aims at monitoring the fluids consumption as well as indoor comfort parameters using robust, wireless, low-energy...
The Generic Bootstrapping Architecture (GBA) is standardized by the Third Generation Partnership Project (3GPP) to provide authentication and data confidentiality based on the existing Mobile Network Operator's (MnO) infrastructure. Unfortunately, this method is not well deployed as the MNO is not always fully trusted by its clients. On the other hand, Transport Layer Security (TLS) is a well-spread...
In this paper, compact size band pass filters are proposed and designed for WLAN applications. The coupled DGS resonators are considered the main block of proposed band pass filters. The three proposed filters are designed by using the same defected ground structure shape, but with different feed line configurations. The feed line configuration affects the presence of transmission zeros in the rejection...
Microwave imaging for breast cancer detection is based on the contrast in electrical properties of healthy fatty breast tissues. This paper presents, an industrial scientific and medical bands (ISM) comparative study of five microstrip patch antennas for microwave imaging at 2.45GHz frequency, a choice of one antenna is made for an antenna array composed by 8 antenna for a microwave breast imaging...
This paper presents a Brain Computer Interface methodology for unspoken speech recognition based on Electroencephalography (EEG). Each phase within this approach is presented and discussed, followed by the noise elimination methodology and ends up by features extraction and data classification. The presented work consists of database construction with features vectors that will be classified into...
In this paper, we propose a new miniaturized Artificial Magnetic Conductor (AMC) for Dual Wide Band operation for Long Term Evolution (LTE) Europe bands. By a patch design, the AMC is proposed in mono band. Next, a square slot is added to achieve a Dual Wide Band AMC (DWBAMC) operation. At the beginning, this design proved to be of a large unit cell. This problem is later solved by reducing the unit...
Copy-move operation is an essential block in most of digital image forgeries. It results in hiding information from a scene, inserting new information or simply duplicating it. Many studies have been made in order to detect this kind of image modifications. In this paper we propose an algorithm that applies principal component analysis and discrete cosine transform in order to characterize and detect...
This paper presents the design of a low cost Electromagnetic Band Gap (EBG) antenna with high gain and mono-band characteristics covering the up/downlink GSM (890–960 MHz). These properties are performed using Plexiglas layers suspended over a ground plane. The principle of Fabry-Perot cavity is used to obtain the high gain performance.
Wireless Multimedia Sensor Network (WMSN) is a promising technology capturing rich multimedia data like audio and video, which can be useful to monitor an environment under surveillance. However, many scenarios in real time monitoring requires 3D depth information. In this research work, we propose to use the disparity map that is computed from two or multiple images, in order to monitor the depth...
This paper presents the modeling of a geothermal heat pump system (GHP) with vertical borehole heat exchangers (BHE). It has been developed to study the feasibility of applying this system to cooling and heating buildings in Beirut using 3E evaluation criteria: energy, economy, and environment using TRNSYS simulation software. All model components are designed, two sizing methods are used for the...
CLARAs backbone (Latin Americas Consortium for Advanced Networks) was stagnated in 2013 with just one 10 Gbps links and ten backbone nodes. In 2016 CLARAs backbone was updated having nine 10 Gbps links ant thirteen backbone nodes. Following CLARA s backbone evolution, simulation as first approach and emulation as a second approach were developed for connectivity and management for each node of the...
In this paper, emotion recognition in Arabic spoken data is studied for the first time. A realistic speech corpus from Arabic TV shows is collected. The videos are labeled by their perceived emotions; namely happy, angry or surprised. Prosodic features are extracted and various classification methods are applied. Results are analyzed in this paper and conclusions and future recommendations are identified.
The accelerometers implanted into smart phones can be used as a self monitoring device for daily physical activity in elderly population. The study goal is to validate the smart phone-based activity monitoring application in adults aged below and above 65 years old. Ten young adults (mean of 33, SD 13.7) and ten elderly (mean 76, SD 5.5) were asked to monitor their daily physical activity with a smart...
A brain computer interface is an artificial intelligence system that provides the brain with a way to communicate with the outside environment. This paper aims to provide guidelines for biomedical researchers by discussing each phase of the construction of a Brain Computer Interface. It explains invasive and noninvasive BCI. Then, it presents the most commons methods employed for designing a BCI and...
This paper introduces a novel low profile microstrip band pass DGS filter for blocking undesired resonant frequencies when higher modes are excited. The proposed filter is combined with a microstrip inset-fed rectangular patch antenna. The higher modes are excited for implementation of DGS band pass filter harmonic rejection. This filtenna structure performs as the combination of a low profile BPF...
