With the huge development in the field of data storing and processing as well as the
impending development of the internet, accessing information and resources is
becoming faster, cheaper and more available. This has paved the way for a new
develo
pment in the world of computing, networks and operating systems, which is
“Cloud Computing”.
In this project, we present a solution for the problem of secure data sharing in a safe
and dynamic way on Public Cloud. The process is done without re-encrypting the
shared data or re-distributing keys as the case in most solutions so far. Also, include a
step towards the completion of access control UCON, where we studied the ability
for a user to delegate another user OWNER role and sharing data authorization.
This research aims to shed a light on the distinctive economic characteristics of water
resources and to identify the reasons that led to increasing interest in studying these
resources and their economics.
depending on descriptive analytical meth
od through characterization of what is and
analyze it, The researcher is addressing the policies necessary to be followed for a
successful allocation of water balances within the time periods, and define whether the
water resources are to be considered as an economical good and whether they are subjected
to market mechanisms, i.e. demand and supply.
the research results pointed out to the fact that the water resource is a strategic vital
resource and an economic good has a special nature which make it not subject to market
mechanisms.
this study is providing a number of proposals that emphasize the need to focus on the
economics of water resources to attain the efficiency of resource exploitation, which, on
the one hand, leads to achieving sustainability of this valuable resource, and on the other
hand fulfill maintain the economic development.

Wireless sensor networks (WSNs) are often deployed by random bestrewing
(airplane bestrewing for example). A majority of nodes cannot obtain their coordinate
beforehand. Therefore, how to obtain the position information of unknown nodes, which is
called localization problem, has become a hot topic in WSN.
Without position information, WSN cannot work properly. Global Position System
(GPS) is the most extensive and mature position system at present. But because the nodes
usually have the shortcoming of high expenditure, large volume, high cost and require
settled basal establishment, therefore, the GPS is inapplicable for the low-cost selfconfigure
sensor networks, and also it is impossible to install GPS for each sensor node. In
this paper, we will study localization mechanisms (which is not based on GPS) used in
WSN, and will test the effectiveness of using MUSIC algorithm in determining the signal
arrival angel depending on the SDMA- technology and ESPAR antenna.
This Paper Attempts to study the latest advancements in High Performance Computing Technologies, Which Provides suitable environments, Solid infrastructure, Software and Hardware Components, allowing Scientists and Researchers to solve Math, Biology,
Machine Learning, Physics Simulations, and numerous other problems, Allowing significant breakthroughs in these fields.
Quantum computing as a promising technology that solves impossible problems in classical computation due to its exponential complexity, superiority, barriers, hardware and software tools, in addition to the state of the art and future vision.
