I am the BRAND on online search engines

For the last 10+ years, many companies approached me and promise a better ranking for Google search and to get my link in the first page. This is the goal of many companies, which may be good.

Over the last two weeks, I was building my website and I deployed my experience on website development  and social media.

I was able to get my name in all links in the first 2 pages of google search and at least 8 out of 10 links in pages 3 – 12 of the search engine. I am now the brand who can appear 105 times out of 120 result  link.

I was able to be dominating the top 27search result out About 130,000 results, It basically demonstrate and I am listed in 134 out of the top 160 and I should conclude that I am the BRAND.

 

Similar results are achieved on Yahoo and BING, and the following images.  The following 17 images prove that my name dominates the top 16 pages search result and the following 2 images show the first pages of Ping and Yahoo search,

 

Can you do me a favour, search my name “Wael Badawy“ from your end on google.com, yahoo.com and bing.com and write in the comment if you find me that I am the Brand in your search

With he explosion of Digital world, everything is going online.

The Internet is a modern day phone book where people look for services, products, information, news, classes, and any number of other items of interest on a global scale. The Internet is accessible 24/7 through our computers, tablets and smart phones (which means we are always plugged in).

The world has changed. Social media is the way people communicate, advertise, promote and sell. It is the 21st century way of connecting. If you are not using social media to communicate and connect with your business, your business might as well be considered a hobby. Get active on Facebook, Twitter, LinkedIn, Instagram and/or Google+ so your business can thrive and build recognition (there are many other social media sites, but these are the big five). You must have a website. If you have a business and no website. People search the internet, cannot find you so you are do not exist.

People look for everything on the Internet. If you cannot be found within the first couple pages of the search results, it is like you do not exist. People are only going to go to the first or second page but they’re not going to go much further to find you. If they don’t find you, you’ve lost a potential client.

The world has gone digital and there is no escaping it. If you are unsure where to start to build your online presence, call me, email me, sign up on my website. I can help you develop your best-self online so you become recognized for the expert you are.

Applying FEA to Investigate the performance of Electrostatic Comb-Drive Actuators Utilized by on-a-chip systems

This study focuses on investigating the design parameters of lateral electrostatic comb-drive actuators, where the effect of these parameters on the actuation performance is explored using finite element analysis (FEA). This level of analysis is essential to the design process of system-on-a-chip microelectromechanical systems (MEMS) applications, where a comb drive can represent the main source of actuation within the chip system. Of particular interest to this study is the application of the electrostatic comb- drive motor as a fluidic pump in on-a-chip systems used for drug delivery or in cooling of microprocessors used in space vehicles. The commercial FE package ANSYS is utilized to construct a robust comb-drive model and solve its multiphysics interaction problem using the direct coupled-field analysis. In this model, the thickness, gap and overlap of the comb fingers are varied. The design of this model is also modulated to account for changes in the number of comb fingers and the applied driving voltage. The calculated comb displacement and generated electrostatic force are shown to be directly proportional to the number of comb fingers. Moreover, the generated electrostatic force is found to be inversely proportional to the gap between the comb fingers. As the thickness of these fingers increases, the displacement is found to increase for a given value of the driving voltage. The electrostatic force is also shown to be proportional to the offset (i.e., overlap) value between the fingers. To facilitate the use of the current study results in optimizing the design process of comb drives, an effort is made in the current work to condense these results into a compact nondimensional form that correlates the geometric and electrical parameters of the studied comb drive to the resulting displacement and force.

Cette e ́tude s’inte ́resse a` l’e ́tude par la me ́thode des e ́le ́ments finis des parame`tres de design des actionneurs e ́lectrostatiques late ́raux en peigne de meˆme que l’effet des parame`tres sur les performances des actionneurs. Une telle finesse d’analyse est ne ́cessaire a` la conception de dispositifs inte ́gre ́s dans les applications de syste`mes micro-e ́lectro-me ́caniques (MEMS) car l’entraˆınement en peigne peut constituer la principale source d’actionnement dans le syste`me inte ́gre ́. L’inte ́reˆt principal de cette approche est qu’elle peut s’appliquer a` la conception de moteurs a` peignes e ́lectrostatiques pour les pompes a` fluides dans les syste`mes sur une puce inte ́gre ́s pour la distribution de doses de me ́dicaments ou pour le refroidissement de micro-processeurs dans les ve ́hicules spatiaux.

Dans le mode`le, on peut modifier l’e ́paisseur, l’espacement et le chevauchement entre les dents du peigne. La conception du mode`le prend aussi en compte la variation du nombre de dents du peigne et des valeurs de la tension d’entraˆınement. Le calcul des de ́placements des dents du peigne et de la force e ́lectrostatique ge ́ne ́re ́e montre leur de ́pendance directement proportionelle au nombre de dents du peigne. De plus, la force e ́lectrostatique ge ́ne ́re ́e est pour sa part inversement proportionnelle a` l’espacement entre les dents du peigne. Pour une valeur fixe de la tension d’entraˆınement, le de ́placement augmente avec l’e ́paisseur des dents du peigne. La force e ́lectrostatique est aussi proportionnelle a` l’offset entre les dents. L’utilisation de cette e ́tude pour l’optimisation du processus de conception de syste`mes d’entraˆınement a` peigne est facilite ́e par la pre ́sentation d’une forme compacte adimensionnelle corre ́lant les parame`tres ge ́ome ́triques et e ́lectriques de l’entraˆınement a` l’e ́tude au de ́placement et a` la force re ́sultants.

A Low Power VLSI Architecture for Mesh-based Video Motion Tracking

This paper proposes a low-power very large-scale integration (VLSI) architecture for motion tracking. It uses a hierarchical adaptive structured mesh that generates a content-based video representation. The proposed mesh is a coarse-to-fine hierarchical two-dimensional mesh that is formed by recursive triangulation of the initial coarse mesh geometry. The structured mesh offers a significant reduction in the number of bits that describe the mesh topology. The motion of the mesh nodes represents the deformation of the video object. The architecture consists of motion estimation and motion compensation units. The motion estimation architecture generates a progressive mesh code and the motion vectors of the mesh nodes. It reduces the power consumption, uses a simpler approach for mesh construction, approximates the mesh nodes motion vector by using the three step search algorithm and uses a parallel motion estimation core to evaluate the mesh nodes motion vectors. Moreover, it maximizes the lifetime of the internal buffers. The motion compensation architecture uses a multiplication-free algorithm for affine transformation, which significantly reduces the complexity of the motion compensation architecture. Moreover, using pipelined affine units contributes to the power savings. The video motion compensation architecture processes a reference frame, mesh nodes and motion vectors to predict a video frame. It implements parallel threads in which each thread implements a pipelined chain of scalable affine units. This motion compensation algorithm allows the use of one simple warping unit to map a hierarchical structure. The affine unit warps the texture of a patch at any level of hierarchical mesh independently. The processor uses a memory serialization unit, which interfaces the memory to the parallel units. The architecture has been prototyped using top-down low-power design methodology. The performance analysis shows that this processor can be used in online object-based video applications such as in MPEG and VRML.

A VLSI Architecture for Video Object Motion Estimation Using a 2D Hierarchical Mesh Model

This paper proposes a novel hierarchical mesh-based video object model and a motion estimation architecture that generates a content-based video object representation. The 2D mesh-based video object is represented using two layers: an alpha plane and a texture. The alpha plane consists of two layers: (1) a mesh layer and (2) a binary layer that defines the object boundary. The texture defines the object’s colors. A new hierarchical adaptive structured mesh represents the mesh layer. The proposed mesh is a coarse-to-fine hierarchical 2D mesh that is formed by recursive triangulation of the initial coarse mesh geometry. The proposed technique reduces the mesh code size and captures the mesh dynamics. The proposed motion estimation architecture generates a progressive mesh code and the motion vectors of the mesh nodes. The performance analysis for the proposed video object representation and the proposed motion estimation architecture shows that they are suitable for very low bit rate online mobile applications and the motion estimation architecture can be used as a building block for MPEG4 codec.

Error-Free Computation of Daubechies Wavelets for Image Compression Applications

A novel encoding scheme for Daubechies wavelets is proposed. The technique eliminates the requirements to approximate the transformation matrix elements; rather, by using algebraic integers, it is possible to obtain exact representations for them. As a result, error-free calculations up to the final reconstruction step can be achieved, which provides considerable improvement in image reconstruction accuracy.

An Optimal Call Admission and Bandwidth Reservation Scheme for Future Wireless Networks

The next generation wireless networks promises availability of a wide variety of services. To be supported successfully, it is necessary to provide quality of service (QoS) between end-systems with the resources whose cost is discouragingly high. This paper proposes a new scheme for call admission and bandwidth reservation for the next generation wireless networks. The proposed scheme OPBR (optimal cell partition based bandwidth reservation) does an optimal partitioning of the cell to give high degree of call admission and successful handoff. In addition it offers effective bandwidth utilization and guarantee QoS. The performance of the scheme is done by analytical modeling and simulation experiments. A comparison with two different schemes (PBR and adaptive reservation) shows desirable results can be achieved by proposed scheme with better performance for various QoS parameters.
