We will measure the Q-factor for four wavelengths downlink Optical-receiver to decide which wavelength has the best performance and cover the longest distance. Among the two data format, we used Return to Zero (RZ) and Non-Return to Zero (NRZ). Then prove how RZ gives higher effectiveness in the contras to NRZ and longer distance to cover specialty the wavelength (1310) followed with (1270) that it could reach 60 km with Q-factor (7.48) and (6.77) respectively.

Moreover, the management of the parking system is also considered a difficult task. Humans, on the other hand, were acclimated to efficiently parking their automobiles by providing them with the precise location of parking in advance of their arrival. As a result of human inefficiency, it was unsuccessful and ultimately increased the compliance cost. As a result of the development of the notion of the Internet of Things. A lot of systems were installed regarding smart parking systems that are decreasing the cost but also contain a huge impact on the reduction of emissions from cars. While it is possible to integrate Internet of Things (IoT) devices into automobiles, such an approach will necessitates the deployment of additional infrastructure, which will raise the cost, and also it is not feasible within current infrastructure configurations. Then there's the fact that CCTV technology is widely available and also small enough to fit into any parking area without being noticeable. In this paper, Convolution Neural Network (CNN) based smart parking system is designed and implemented. The CNN is used to detect vacant and occupied parking spaces through CCTV cameras and provide feedback to the passengers. Furthermore, the proposed approach is using CNR and PKLot datasets for ensuring the effectiveness of the model. This was developed to solve the issues of time, cost, and accuracy with the existing systems. As a result, the proposed model provides excellent results in terms of accuracy. Moreover, it is cost-effective and saves time.

This system can be severely limited by dispersion as we know smaller the dispersion the better the Q-factor but we will prove, not always the smaller the dispersion the better the Q-factor as we will see in some distance like 60,80 km the best performance is done with dispersion equal to 4, 6 and sometime 8 ns/nm.km not 2.

NG-PON2 architecture has the capability to support power-split and wavelength-split optical distribution network (ODN) as well as a hybrid of two ODNs. Wavelength routing (WR) ODN has adequate low insertion loss than the power splitter (PS) ODN which can fulfill the exponential increase in demand for greater connectivity. The wavelength routing passive optical network (WR-PON) is investigated using the OptiSystem-13 simulation design tool. In this paper, we optimize the downstream transmission of eight channels WR-PON over 60 km and 40 km of standard single mode practical fibers (G.655 and G.652) with 10 Gb/s per channel and compared it with PS-ODN based passive optical network (PON). Both WR-PON and PS-PON are analyzed in detail under the specifications of deployed optical fibers like ITU-T G.652.A fiber, ITU-T G.652.B fiber, Alcatel 6912 Tealight Ultra 1625 fiber, Corning LEAF 1625 fiber, and Lucent True-Wave RS 1625 fiber. Next generation multiwavelength system performance is limited predominantly due to fiber dispersion and nonlinearities. Fiber nonlinearities and dispersions are mitigated and performance is enhanced by characterizing the system and optimizing optical launch power for both WR-PON and PS-PON. Furthermore, the effect of optical launch power on performance is investigated and evaluated for each practical fiber configuration with common optical modulation formats, return to zero external modulation (RZ-EM) and non-return to zero external modulation (NRZ-EM). Power budget for each configuration is calculated and tabulated.

In recent decades, social media platforms such as Twitter, Facebook, Linkedin, Instagram have become valuable sources of information in disaster times. However, the reliability, volume, and velocity of information remain a major concern; this is particular about information issued from disaster locations. This paper proposes an approach for tracking the location of people in danger during times of disaster. The procedure is based on the Twitter application programming interface (API) by using natural language processing (NLP) and big data tools. A number of tweets were analyzed and an accuracy of 86.11% was actualized.

Even with this solution, there are many other problems like the influence of haze and fog in the propagation channel which obstruct and scatter OWC propagation light and consequently led to a big attenuation, due to propagate in temporal, angular and spatial of the light signal. Not to mention the minimum visibility that discourages the implementation of the pointing errors (PE) and tracking system. This present work aims to analyze the interrelation between multiple scattering (dense fog, heavy fog, light fog, heavy haze and light haze) and receiver PE under modified duo-binary return-to-zero (MDRZ) system. We found that PE caused by beam swag is the main controlling factor and industriously minimize the link margin, signal-to-noise ratio (SNR), and raise the bit error rate (BER) when th...

The retail industry took infant steps in the early 20th century across most of Europe and America. However, there was a considerable surge in the rise of supermarkets and hypermarkets in 2nd half of the century as they provided a convenient all-in-one-stop experience for customers. This subsequently created a huge growth of data in retail stores which presented a challenge for store owners to interpret with traditional business intelligence tools. Therefore, there was a need for real-time analytic tools to handle large datasets in sizes of up to Terabyte magnitudes. Query languages such as Hive and Pig became prominent in the analysis of customer data to ensure continued convenient experience for customers and quality provision of services for retailers. In this paper we analyze the underlying factors that have made...

Java enabled two different machines to communicate securely and exchange all kinds of information with the help of certain technologies. Remote Method Invocation (RMI) API is one of the most used interfaces in many applications that require communicating between two machines also in cloud processing. This paper investigates the encryption algorithms which are used with the RMI to ensure security on the transmitted data or objects. Specifically, Advanced Encryption Standards (AES) and Data Encryption Standards (DES) algorithms are applied to this experiment. This paper will also explore the differences between both algorithms with the RMI API. Furthermore, a comparison between the AES and DES algorithms in RMI usage is presented.
