NVE Corporation was founded in 1989 in Eden Prairie, Minnesota. Originally called Nonvolatile Electronics, the company changed its name to NVE Corporation after going public on the Nasdaq stock exchange in 2000; their ticker symbol is NVEC. The word “nonvolatile” refers to memory that retains information after a power source has been removed. Since their founding, NVEC has been granted over $50 million in government research contracts, especially for their research in the nonvolatile memory called MRAM or magnetoresistive random access memory. These contracts helped NVEC develop an intellectual property portfolio and accumulate over 50 patents regarding spintronic and MRAM technology. Recently the company has reduced their dependence on research contracts and has grown tremendously through product sales, averaging an increase of 25% top-line growth the past three years.
The company develops and sells products that utilize “spintronics”, a nanotechnology which relies on electron spin rather than electron charge to gather, store and send information. NVE Corp. manufactures high performance sensors and couplers that are used to acquire and transmit data. Additionally, they license their MRAM technology to various companies including Avago Technologies, Honeywell, Cypress Semiconductor Company, and until 2006, Motorola. As of fiscal year 2008, product sales accounted for 85% of revenue and research and development contracts accounted for 15%. They currently have 50 employees and generate sales in over 75 countries.
The electronics industry relies heavily on devices that acquire, store and transmit data. NVE Corp’s spintronics technology focuses on magnetic sensors, couplers, and memory which perform these activities w...

...y without booting up, enabling a user to simply push a button and the computer will turn exactly as it was when it was turned off. Mobile devices will benefit from MRAM as it has less power demands, allowing for much longer uses on a single charge. Further, MRAM’s durability and low power needs make it ideal for defense and aerospace technologies as well as for the primary data storage technology for satellites.
NVE Corp. has patents on advanced MRAM designs which include vertical transport MRAM, magnetothermal MRAM, and spin-momentum transfer MRAM. These advanced designs are aimed to resolve the current hindrances of MRAM technology; mainly, lowering manufacturing costs while increasing memory density. Due to MRAM’s more expensive production costs and larger relative size than DRAM and Flash RAM, they are slowly being integrated into electronics devices.

The defense of our nation and its allies across the globe is essential to the success of the world we live in. The methods in which this defense takes place varies in many different ways, in air, on land, and at sea. Within our nation lies some of the largest defense organizations on the face of the planet, most, if not all, of which strive to protect the United States of America in all arenas. One of these organizations is Northrop Grumman. Northrop Grumman is one of the largest global aerospace and defense technology companies in the world. The company employs over 68,000 employees worldwide, and was named as the fourth-largest defense contractor in the world in 2016 (Forbes, 2016). It grossed over $23.526 billion in 2015.

However, RLK’s competitors are downsizing and outsourcing R&D and exploiting on the cost advantages. If RLK decides to invest more money into R&D and should the new product stall on launch, they face the danger of becoming bankrupt.
Electronic Applications was found in 1972, its headquarters are on San Francisco and it is a major producer of silicon chips. The company’s sales, profit and stock price have grown fast on the past years while the human resources policies have remained unchanged.
PROBLEM STATEMENT Teva Pharmaceuticals, the first multinational pharmaceutical company in Israel, has become a successful global giant in the industry of generic drugs. After experiencing a long period of success and growth in the generic drug industry against some big western pharmaceuticals, the company had acquired many well known pharmaceutical companies and had achieved its goal of $1 billion. theory seemed to be in trouble in building a new strategy and vision to compete with the rapidly growing generic industry. They confronted two big issues as key hurdles in their way.

Due to the advances in recent computer technologies, computers are now sold with state-of-the-art, costly equipment that most people do not need. Most computers on the market these days are built to attract the eye of the consumer. They come loaded with hi-tech hardware and catchy tag words like mega RAM, quad-speed drives and digital processing, but the fact is, the computer has been exploited to the American public to attract a broader base of consumers and to change the way we view computers from tools to toys. The modern age has brought countless advances and the most sophisticated technologies the world has ever seen. Over the years, we have all marveled at the exciting developments in the fields of science and electronics.
The Von Neumann bottleneck is a limitation on material or data caused by the standard personal computer architecture. Earlier computers were fed programs and data for processing while they were running. Von Neumann created the idea behind the stored program computer, our current standard model. In the Von Neumann architecture, programs and data are detained or held in memory, the processor and memory are separate consequently data moves between the two. In that configuration, latency or dormancy is unavoidable. In recent years, processor speeds have increased considerably. Memory enhancements, in contrast, have mostly been in size or volume. This enhancement gives it the ability to store more data in less space; instead of focusing on transfer rates. As the speeds have increased, the processors now have spent an increasing amount of time idle, waiting for data to be fetched from the memory. All in all, No matter how fast or powerful a...
The magnetic susceptibility χ (=M/H) (FC and ZFC) as a function of temperature measured at low applied field (H=50 Oe) is presented in Fig.5. The molar susceptibility shows a monotonic increase upon cooling down to ~ 22 K, where a steeper increase is observed. Below this temperature a bifurcation between the ZFC and the FC curves is evident (see inset of Fig.5. On the other and above 22 K the reciprocal magnetic susceptibility (1/χ) as a function of temperature shows a linear trend (Fig. 5 right scale). In detail, above ca. 30 K, in the paramagnetic region, the Curie-Weiss law is strictly followed. By fitting the linear part of the 1/χ curve with 1/χ = (T-p)/C, in the 30-310 K temperature range, a Curie-Weiss temperature, p = -2.3 K, and the Curie constant, C = 1.30 cm3.K.mol-1, (µeff = 3.2 µB) were obtained. The small negative Curie-Weiss temperature indicates the presence weak antiferromagnetic exchangeinteraction between the Ni magnetic centres. Indeed, the χT curve (Fig. 6 left scale) shows a downward curvature, typical of systems with antiferromagnetic correlations and/or non-negligible spin-orbit coupling. The χT=1.31 cm3.K.mol-1 at 310 K undergoes a small and gradual decrease to 1.19 emu.K.mol-1 at 24.5 K. The Curie constant value, either obtained by1/χ linear fit or the χT product for T>>p is in reasonable agreement with the expected spin-only theoretical value for NiII in octahedral environment with S=1 spin state (C = 1 cm3.K.mol-1and µeff = 2.83 µB considering g = 2) for unquenched orbital moment C = 3.91 cm3.K.mol-1and µeff = 5.59 µB).

As a graduate student, I will undertake research and coursework in Electrical Engineering to enhance my competencies in this field. I intend to complete my master's degree in order to pursue my doctorate. The research that I am most interested in pursuing at Northeastern University surrounds the optical properties of MEMS devices, and the development of substrate-based fast electro-optical interfaces. My interest in this area stems from my undergraduate study in MEMs development for tri-axial accelerometers.
The topic of magnetic disks is one that involves many physics related phenomenon. The intricate structure and design of “Magnetic Disks” (or hard disks) in computers include the principles of Fluid Flow, Rotational Motion, Electromagnetism, and more. This paper will focus mainly on the previously listed physics occurrences, and the design that goes into engineering the magnetic disk to include them. These physics principles are utilized in such a way that makes the hard disk a very common and useful tool, in this day and age. To most people, the magnetic disk is the most important, yet most mysterious, part of a computer system. A hard disk is a seal unit that holds computer data in the form of magnetic patterns.
