Use the papers/presentations: Gies, “Safety Considerations for Smart Grid Technology
Equipment,” Chopra, “Remarks to IEEE International Conference on SmartGridComm,” and
Budka, et.al., “GERI – Bell Labs Smart Grid Research Focus:Economic Modeling,
Networking, and Security & Privacy” to answer the following.

[5 points] According to Gies, in basic, high level terms, what is the smart grid?
According to Gies, what is the best approach to approach the formerly separated industries of the smart grid?
a. A smart grid combines the existing electrical infrastructure with digital technologies and advanced applications to provide a much more efficient, reliable and cost effective way to distribute energy.
b. The best way to approach this new, merged technology is to break it down into its component technologies, then use existing or new standards to evaluate safety issues involving the component technologies.

[5 points] Describe how the evolution of the power grid differs from that of the telecommunication system, from the perspective of Alexander Graham Bell and
Thomas Edison being alive in the 21st century.

It is said that Alexander Graham Bell would not recognize the components of modern telephony, while Thomas Edison would be totally familiar with the modern electrical grid.
Thus, with smart grid, there is the potential to modernize and advance the architecture of the power systems technology in the 21st century, as the newer technology has already advanced the telecommunications technology.

[5 points]

Why is synchronization important for renewables and generators?

Moreover, why does synchronization become more critical as the number of renewables connected to the grid increases?
A. In renewable and distributed generation systems the grid voltage quality can be poor. So,

Database Hw2

...2.1 Define the following terms: Data Model – a collection of concepts that can be used to describe the structure of a database i.e. the types, relationships and the constraints that should hold good on the data contained in the database. Database Schema – The description of a database is called its database schema. Database State – The data in the database at a particular moment in time is called a database state. It is also called the current set of occurrences or instances in the database. Internal Schema – Internal Schema is one of the major parts of the Three Schema Architecture of a Database. It describes the physical storage structure of the database. Conceptual Schema –is a map of concepts  and their  relationships used for databases.  The conceptual schema hides the details of physical storage structures and concentrates on describing entities, data types, relationships, user operations, and constraints. External Schema -- External Schema describes the part of the database that a particular user group is interested in and hides the rest of the database from that user group. Data Independence – the capacity to change the schema at one level of a database system without having to change the schema at the next higher level. DDL – DDL or Data Definition Language is used to specify conceptual and internal schemas for the database and mappings. DML – DML or Data Manipulation Language as the name suggests is used for typical manipulations include retrieval,......

...1. Describe what a greenhouse gas is and give examples of the common greenhouse gases. Why are greenhouse gases important to surface energy balance? A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect Examples of common greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, Chlorofluorocarbons, and ozone. Greenhouse gases strongly absorb the earth’s thermal infrared radiation, so they blanket the earth and reduce the cooling of the earth to space. Without these so-called greenhouse gases, the surface of the earth would be about 30 degrees Celsius cooler, it is too cold for life to exist. 2. What is shortwave radiation? What is longwave radiation? Shortwave radiation is basically radiant energy (light) in the visible, near infrared and near ultraviolet spectrum. Longwave radiation is the energy leaving the Earth as infrared radiation at low energy to Space. 3. Trends in Atmospheric Carbon Dioxide - Mauna Loa http://www.esrl.noaa.gov/gmd/ccgg/trends/ Observed the plot and briefly describe the overall variation in CO2 from year 2009 to present and seasonality.

...Allen Saparzadeh Econ 330 HW2 1. What do Neo-Classical Economists argue causes unemployment?  Be very specific…is it good or bad for the economy, fair or unfair, voluntary or involuntary, etc.  Explain carefully. Neoclassical Economists believe that discrepancy in wages causes unemployment. They also believe that all types of unemployment are voluntary, efficient, fair, random, and self –correcting [by supply and demand]. They believe that a certain degree of unemployment is healthy. Types of unemployment include structural, frictional, and seasonal unemployment. 2. How does Keynes critique, and thus modify, the Neoclassical view of unemployment?  Describe his contributions to the theories of unemployment. Keynes describes unemployment as non-voluntary, unfair, inefficient, and does not believe that it will fix itself. He believes that unemployment is related to business cycles and that unemployment undergoes a positive feedback (unemployment leads to more unemployment). Keynes and other political economists believe that government intervention may be necessary to fix the unemployment issue. 3. Discuss what the gender gap is and the short and long-term impact it has on women and their families.   The gender gap is the ration between women’s wages and men’s wages for full time workers. Women on average make 77 cents for every dollar a man makes. Economists evaluate women make over $11,000 less a year, accumulating a gap of over $400,000 in her lifetime. ...

...Trans-Pacific Partnership In the present moment, President Obama is anxious to sign apparently on of the biggest trade deals in U.S. history. The name of this agreement is the Trans-Pacific Partnership (TPP). TPP is basically a proposed trade agreement between many Pacific Rim countries concerning a variety of matters of economic policy. This would link 11 countries on the Rim with America. This is extreme because the 12 countries account for 40% of the world GDP and one third of all trade (The Economist). Let alone taking down tariff barriers, the TPP is supposed to tackle things like intellectual property, labor and environmental standards. In my opinion, I would support the Partnership. The reason I would support the Trans-Pacific Partnership because of all of the advantages this deal has to offer. What the TPP does is boost exports and economic growth. As a result, this will create more jobs and prosperity for the 12 countries involved that make up 40% of the GDP. The exports would be focusing mainly on machinery, especially electrical, automotive, plastic, and agricultural industries (US Economy). Trade negotiators have predicted that this deal will make the world richer by it earning $220 billion more a year. This deal will create economic and stronger political ties with Asian allies, and this could help America retain some influence in Asia. This deal can really put the U.S. as one of the dominant leaders. Although this deal has many advantages, it...
