Kjo energji matet në rrezatim, që është sasia e energjisë së dritës të marrë nga një sipërfaqe për zonën e njësisë. E thënë ndryshe, rrezatimi mund të përkufizohet si prodhim i energjisë së dritës nga dielli, ndërsa matet në tokë. Me gjatësi vale fotonike që variojnë nga rrezet X dhe rrezet gama, kjo energji e dritës bëhet e dukshme me anë të teknologjisë infra të kuqe dhe radio. Sot, teknologjia fotovoltaike është bërë një nga burimet më të rëndësishme të botës për të gjeneruar energji të pafundme Ky punim përqendrohet në potencialin e energjisë diellore, të mirat dhe të metat e tij. Zhvillimi i teknologjisë moderne fotovoltaike konsiderohet si një nga zgjidhjet për të përmbushur kërkesën në rritje për prodhimin e energjisë elektrike. Studiuesit hulumtuan rritjen e shpejtë të teknologjisë diellore dhe të disa pengesave teknike që vazhdojnë, kryesisht një efikasitet të ulët të qelizave PV, një ekuilibër të ...

Special cases of the LCT include the fractional Fourier transform (FRT), the Fourier transform (FT) and the Fresnel Transform (FST) describing free space propagation. We have recently published theory for the Discrete Linear Canonical Transform (DLCT), which is to the LCT what the Discrete Fourier Transform (DFT) is to the FT and we have derived the Fast Linear Canonical Transform (FLCT), a NlogN, algorithm for ...

However, time requirements for large two-dimensional image transforms are hard to meet with sequential implementations. Parallel implementation decreases the processing time and allows to reach a real-time operation in image coding. Unfortunately, this parallel coding increases the hardware complexity. We propose an optical implementation of the JPEG2000 compression using a special implementation of the WT. Special attention is paid to propose a simple all optical setup carrying out the optical implementation of JPEG2000 compression for gray-level images. Finally, an adaptation of our technique to colored images is proposed.
ABSTRACT In case of transmission of fast and protected information, it is important to carry out ... more ABSTRACT In case of transmission of fast and protected information, it is important to carry out two operations distinctly. The first, is an operation of encryption, which aims to modify the compressed information to make them unreadable to whoever does not have the necessary authorization to see them (in this paper, we propose give this authorization by using a fingerprint image). The second is an operation of compression which consists in reducing the size of information to be transmitted, by removing redundant information of them. However, these two operations are often carried out separately, although they are strongly bound and one influences on the other. We propose, in this article, to carry out these two operations (compression and encryption) together with a new system able to amalgamate spectral information. This nondestructive spectral fusion, allowing at the same time the compression and the encryption of this information. This system is based on one hand on the rarity of similitude in two different fingerprints and on the second hand on the Discrete Cosine Transformation "DCT", a transformation used for a long time in JPEG compression.

Elimination of redundancies and non-pertinent information enables memory space minimization and thus faster data transmission. The present work aims to improve the quality of the compressed image while minimizing the time required for compression by using the principle of coherent optics. We present an optical adaptation of the method of JPEG compression technique for binary, gray-level and color images. Illustrative simulations will be given at the end to validate our architecture and to evaluate the performance on different types of images (binary, gray and color). An optical implementation setup is proposed and validated experimentally.

Since more than 23 years, Republic of Yemen is going from darkness to darkness in the field of electricity power sector. It is considered as one of chronic problem in the country since 1990 up to now. The next 10 years Yemen meets a huge and serious problem in electrical power sector more than ever. Renewable Energy is considered as one of optimal solutions for power sector in Yemen which is called Solar, Wind and Geothermal energies. The objective of this work is to study and analyse existing status of power sector in Yemen and introduce the advantages of renewable energy resources. In depth study about solar and wind energy is presented in this paper. Renewable energy could enhance electrical grid system in Yemen and generate the green energy for Yemeni rural areas to serve: education sector, lightening homes, and medical clinics, etc. The importance of this paper is to illustrate the features of clean energy to enh...

Pour gagner aussi bien en temps qu’en memoire, il est necessaire de compresser ces images tout en gardant une bonne qualite. Cependant, malgre l’origine optique de l’image, le traitement se fait souvent numeriquement. Ce qui entraine une perte de temps lie a la numerisation de cette image avant de pouvoir appliquer l’algorithme de compression souhaitee. De plus, comprimer numeriquement des informations de plus en plus complexes (images hautes resolutions par exemple) exige des temps de calcul tres couteux, malgre les progres de l’informatique. Cette these traite le probleme de la compression des images fixes, mais d’un point de vue de l’implantation optique afin de reduire la taille de l’information en eliminant les informations redondan...

Although, there are many algorithms that all of them are aiming - at the end - to decrease collision state numbers or to process such states that help achieve an accurate identification process in an acceptable period of time. In this paper, we intend to propose an algorithm offering balanced performance in general and excellent performance in environments with low or medium tags population. It gives the ability to reduce the number of collisions, in the first stage, and to identify tags that failed to be identified due to the occurred collisions, in the next stage. For illustration, we present simulation showing our algorithm performance against some commonly used algorithms.

Yemeni towns in general are considered as non-urban cities. However, it is difficult for telecommunication engineers to find many options for the distribution of cellular base stations.The aims of this paper is to measure the radiofrequency radiation near of the schools, hospitals, universities, and crowded populated areas.Theimportance of this studyis to focus on invisible pollution in Yemen because noone cares about this topic even ministry of telecommunication and information technology. Accordingly, there is a mandated radiofrequency radiation from cellular base stations unmatched worldwide. Experimental results of long term during specific points and 24 hours at fixed points, and...

Today, the photovoltaic systems technology sector is exponentially expanding in the international energy market. The aim of this paper is to study, compare, and analyze this important field in related countries and propose solutions to develop and encourage a solar energy market in Albania, where the economy has been gradually increasing in the last ten years. The potential for a renewable energy sector in Albania is promising, mainly because of the important presence of wind and solar energy resources. An additional objective of this study is to try to apply the results obtained in similar countries in the Balkans to increase the socioeconomic benefits and the creation of job opportunities in the country, as well as contributing to the protection of the environment and economic growth.
