Applications Of Holographic Memory Computer Science Essay

Applications Of Holographic Memory Computer Science Essay From the beginning generation of computer, speed of the processors has been increasing tremendously approximately twice the capacity for every 3 years. Today, we can access large amount of data with in few seconds using CPU and data storage. While the computer evolves many applications for large binary files like sound or image data for high capacity storage and data access. But, there is no high capacity form of data storage to handle these large files quickly and efficiently. So, Holographic memory is a hopeful technology in the next generation over conventional storage system because it is a three-dimensional data storage system that can store information at high density inside the crystal or photopolymer which has a capacity to Storage system, the data of entire page can be accessed at a time instead of sequential method and there are very few moving parts so the limitations of the mechanical motion can be minimized. To trace interference patterns it uses a photosensitive materi al of a reference beam and a signal beam of coherent light, while the signal beam is reflected off and an object or which contains information in the variety of light and dark areas. The natural history of the photosensitive material is to record the interference pattern which reproduce a beam of light to the material which matches to the reference beam. The resultant light that is transmitted through the medium will take on the recorded interference pattern and will be collected on a laser detector array that encompasses the entire surface of the holographic medium. Lots of holograms are recorded in the similar space by changing the wavelength of the incident light or angle. The whole page of data can be accessed in this way. Hence holographic storage system has the potential to became the next storage generation over conventional storage 2. Definition of Holographic Memory It is a storage device which records binary information into one of holograms, then produces (as interfering patterns) on photographic or photo chromic media by the way of laser beams, which can be read by low-power laser beams. It is a technique that can store information at high density inside the crystals or photopolymers. The main advantage of a hologram is that which has an image to be dispersed over the recording surface. So, there is no chance of dust or scratches that totally obscures information though they may deduce the contrast. There are many attempts done on many projects to apply this technology but none of them been commercially successful. 3. What is HVD? HVD known as Holographic Versatile Disc which is an optical technology still in the development stage which holds up to 4 terabyte of information. It has an technique called as collinear holography, which contains two lasers, first red laser and another is known as blue-green laser which collimated in a single beam. The second laser i.e. blue-green laser reads the data programmed as on laser interference outer reaches fro m a holographic layer near to the top of the disc where the reference beam uses the red laser and to study the information of servo from a usual CD-style aluminium layer close to the bottom.

Strategic Management - Research Proposal Example The signing of new contracts and venturing into new partnerships is a way in which this can be achieved. However, there is the question of the transaction cost. That is to say, the cost incurred during the process of an exchange. Williamson’s transaction cost approach assumes that the transaction is the fundamental unit of analysis and through understanding its economization one is able to evaluate how their governing structures serve in their economization. In short, to understand a transaction, one must scrutinize the terms under which the transaction is taking place and ensure it is in the interest of the business. Asset specificity refers to the features of an asset that make it useful for single or multiple specific purposes and is the most important dimension (The economics of organization: The transaction cost approach – AcaWiki 4). Based on this, the more the specificity of an asset, the lower its chances for resale or redeployment. An example is workers trained to perform only a single task. Uncertainty basically is the state of an asset being unreliable to the goal. Uncertainty differs from risk in that risk can be measured through prior or situational probability while uncertainty is not measurable at all. Being a multidimensional aspect, it holds an important role in the decision making process of the stakeholders, thus must be taken into consideration before contracts are signed. Lastly the frequency is the repeated times in which a transaction will occur between specific or multiple parties. Also, one has to consider the frequency of disturbance in the market. This is to say, the adaptation of the market to the change that is brought about with the transaction. This has to be accounted for, such that it must be known if the transaction is a one time deal or will it will be repeated. Having considered all the above in the for the transaction

Reflective portfolio - Essay Example Personally, I opted to volunteer with the National Society of clean Air (NSCA) organization. It is an organization that enhances the protection of environment, and advocates for clean air in the world. Its main objective is to see reduced pollution of land, air, water, noise and other harmful contaminants. In my entire time of volunteering, I was able to create a significant impact on various communities through the creation of awareness on the importance of keeping our environment healthy. Communities in which I served were able to understand the importance of vegetation cover and disposing of wastes in an environmentally friendly manner. The planet is contaminated and without any environmental efforts to return to its natural state then people will perish over time. Our environment is suffering from the impacts of global warming. There is a need to reduce the amount of green house gases emitted into the air through the adoption of cleaner production technologies and increasing on t he vegetation cover. Evaluating the contribution of volunteering in meeting the organization objective Support from volunteers and organization leadership are fundamental in the success of an organization (Warner et al 2011, p.391). Without the two, then successful movements in sentiment transformation in various levels such as political, personal or professional cannot thrive. In order for the continual culture of improvements environmentally, volunteers at the community level are an essential commodity. Volunteers are effective in providing adequate service and remarkably efficient in reducing the organization spending costs. They always offer their services free of charge (Levine & Agostino 2010, p.711). However, because of their increased numbers, organizations have not been able to accommodate them. Non-profit organizations such as National Society of clean Air have been able to utilize skilled volunteers in meeting the needs of the community and meet its goals and objectives. Volunteers in environmental organization have been at the forefront advocating for Natural resource management (Measham &Barnett 2008, p.538). They are tasked by the organization to pass information to the community on the importance of managing their resources effectively. This is through the development of brochures that have information on natural resource management and holding campaigns where communities are able to air their views. The interaction between the community and volunteers enable an organization to identify loopholes that exists and come up with strategies that can enable them fix the problem. Through volunteering, the volunteers have been able to acquire necessary skills that make them sell like hot cake in the job market. Some have become environmental activists. They advocate for policies that will enhance the improvement and point fingers at those organizations that are not operating in an environmental sound manner. The volunteers in the organization involve th emselves in activities such as botanical specimen collection to enhance their understanding of ecology. They also involve themselves in monitoring and evaluation programs. This develops their mind in criticizing where things are not right. Through the volunteers, the organization has been able to achieve its aim of protecting the environment and ensuring that the air individuals’ breath is clean. Through sensitization, the community and other stakeholders have
