Nanostructured solar cells have multiple approaches by which they can improve photovoltaic performance through new physical approaches in order to reach thermodynamic limits of energy conversion, circumventing material limitations through bandgap engineered systems and providing new routes for low-cost fabrication by self-assembly or design of new materials. In the present talk, we focus on pathways...
File carving tools carry out file recovery whenever the file-system meta-data is not available, which makes them a valuable addition to the cyber crime investigator's toolkit. Existing file carvers either cannot handle fragmented files or require a probabilistic model derived using a number of training images. This training data may not always be feasible to aggregate or its sheer size could undermine...
Mobile video consumption and applications are limited by the bandwidth of the communications channel and the resources on the devices. In this work, the latter limitations are alleviated through the use of the Cloud to render high definition video in free-viewpoint applications. A Cloud-based system is developed to port the free-viewpoint application into a distributed and multithreaded environment...
Security and privacy challenges are the most important obstacles for the advancement of IT-based on-demand services and cloud computing as an emerging technology. To ensure data confidentiality and fine-grained access control in cloud-based environments, stored data and resources needs to be re-encrypted periodically or based on special mechanisms such as revoked user-based or manual re-encryption...
In this paper, non-orthogonal multiple access (NOMA) with successive interference cancellation (SIC) technique for downlink channel of next generation wireless network and its security issues are discussed. In NOMA, signals for all user equipment (UEs) are superimposed before transmission and then decoded at each UE implementing SIC. SIC relies on decoding and subtracting the signals in sequence until...
In buildings with enough network infrastructure, there is a fire alarm network controlled by a Fire Alarm Control Panel (FACP) and interfaced with the overall building network. When a fire starts in the building, the FACP takes some actions to facilitate evacuation and firefighting procedures. The fire alarm network, already fire protected, continues to operate on batteries. The fire department dispatches...
A new coherent optical transmission system is proposed that makes use of the digital multicarrier fractional Fourier transform to obtain serial optical Nyquist pulses at the receiver side in the time domain by adopting the time-lens effect. Theoretical time-lens effect is derived based on fractional Fourier transform (FrFT) and chromatic dispersion effect. A fundamental study to explore the limits...
This paper introduces a cost effective scheme for a Cloud Radio Access Network (C-RAN) based on virtualization, which is a technology used to reduce Power Consumption (PC) in the Base Band Unit (BBU pool). The BBU's function is proposed to be as a software application running in a servers, which is called the virtual BBU (vBBU). To asses the proposal scheme, a power model of the BBU pool is proposed...
