The document summarizes the components and variables involved in human walking and why it is considered a closed-loop operation. The major components are the brain, eyes, and legs/feet. The brain determines the control action based on the difference between the desired walking direction input and the actual direction detected by the eyes and sends commands to the legs/feet to walk in the prescribed direction, making walking a closed-loop system where the control action depends on the output.

1. Describe in a simplied way, the components and variables of the physiological system
involved in human walking in a specific direction.
2. Why is walking considered a closed-loop operation?
Solution
( a ) The major components involved in walking are the brain, eyes, and legs and feet. The input
may be
chosen as the desired walk direction, and the output the actual walk direction. The control action
is
determined by the eyes, which detect the difference between the input and output and send this
information to the brain. The brain commands the legs and feet to walk in the prescribed
direction.
( b ) Walking is a closed-loop operation because the control action is a function of the output.

For our discussion question, we focus on recent trends in security technologies and security operations. Staying current with various security tools is an important characteristic of a proficient security manager. One method to discover new technologies is to attend security related conferences and network with other security professionals about current and trending best practices. For your discussion question, choose two relevant and recent physical security technologies and describe them. As part of your detailed description, provide: 1) Specific information about the technology\'s function and application; 2) The type of facilities that the technology would be best suited for; 3) The assets that the technology would best be used to protect; 4) The likely vulnerabilities that the technology would best address; 5) Methods in which the technology would be integrated with other technologies; 6) The number and type of personnel that will need to be committed to the operation of the technology; 7) Special considerations for policies and procedures to fully implement the technology; and 8) A likely budget needed to implement the technology. If you are impressed with a particular security technology that your organization uses, share it. Include any relevant hyperlinks and attach any pictures if applicable. Here are some security categories of technologies that you may select. Please make sure your posting covers a specific technology rather than a broad category: Intrusion Detection Screening Technologies Access Control Technologies Assessment/Surveillance Technologies Communications Technologies Central Control Technologies Security Lighting Make certain that you do not duplicate another student\'s contribution. You can select a “different” technology from the same category. Solution Information Security management is a process of defining the security controls in order to protect the information assets. Security Program The first action of a management program to implement information security is to have a security program in place. Though some argue the first act would be to gain some real \"proof of concept\" \"explainable thru display on the monitor screen\" security knowledge. Start with maybe understanding where OS passwords are stored within the code inside a file within a directory. If you don\'t understand Operating Systems at the root directory level maybe you should seek out advice from somebody who does before even beginning to implement security program management and objectives. Security Program Objectives Protect the company and its assets. Manage Risks by Identifying assets, discovering threats and estimating the risk Provide direction for security activities by framing of information security policies, procedures, standards, guidelines and baselines Information Classification Security Organization and Security Education Security Management Responsibilities Determining objectives, scope, policies,re expected to be accomplished fr.

Explain How Culture influences the way mangers perform their four main functions: planning , organizing, leading and controlling. Solution culture is the the set of aged- old traditions and beliefs shared by the people in an organisation or in a nation. culture plays an important role while when people are at managers level. every decision or step takes by the person reflects his culture directly or indirectly. some people thinks in a pesimistic way and take poor decisions, some may think in a positive way and some may think in the realistic way and take correct decisions. these people will be plan in a successful way and implement them and get positive results. organising is the process of implementing the plan in a proper way by coordination, integration and cooperation of all his peers and emloyees. leading is the process where he becomes the guide to his followers and accept challanges in work life and ready to face them and find solutions. controlling speaks about the managing all the resources and best utilisation of those. the ultimate moto of any organisation is use the available resources in a best way and increase the brand name and wealth of organisation..

Describe the factors that contribute to a membrane potential. What is the principle cation inside the cell? Outside the cell? Solution Answer: Application of stimuli changes the membrane potential that act as signals, transmitting and processing information along the neuron. The factors that contribute to membrane potential are: (a) Electrochemical gradient of the ion: Active transport of ions causes an electrical gradient to develop across the membrane. The positively charged ions are generally greater outside the cell and negatively charged ions inside the cell. This causes a net negative charge on the inside of the cell and thus a voltage difference across the membrane. This gives rise to the membrane potential. (b) Permeability of the ion: More the membrane is permeable to the ion, greater will be the influence of the equilibrium potential of that ion towards the membrane potential. The principle cation inside the cell is potassium (K+) and outside the cell is sodium (Na+)..

Define and explain chemical equilibrium? Include the defenition of reactants and products Define and explain chemical equilibrium? Include the defenition of reactants and products Solution In a chemical reaction, chemical equilibrium is the state in which both reactants and products are available at concentrations which have no further inclination to change with time. Usually, this state comes about when the forward reaction continues at an indistinguishable rate from the reverse reaction. The reaction rates of the forward and backward reactions are, for the most part, not zero, but rather equal. In this way, there are no net changes in the concentrations of the reactant(s) and product(s). Reactant: The substances that outcome from the recombination of molecules is known as the products of the reaction. At the point when chemical reactions are written down, the reactants are written on the left side, in a similar way to a math equation; one reactant in addition to another. Product: Products are the species formed from chemical reactions. Amid a chemical reaction, reactants are transformed into products in the wake of going through a high vitality transition state. Simply the substances that are formed after the reactions of reactant, due to making of new bonds in between the atoms/ions/molecules/compounds..

Cite the distinction between graphite and carbon. Carbon and graphite fibers are manufactured by pyrolysis. Describe the process to produce fibers. Solution Carbon: 1)“Carbon” comes from the Latin word “carbo,” which in English means “charcoal.” It is an element represented as the letter “C” and bearing the atomic number 6. Carbon is the fourth most abundant element in the world and is essential to all living things and their respective processes. All living things contain carbon. 2)Carbon produces the softest material (graphite) and the hardest substance (diamond). The main difference among carbon substances is how the carbon forms in each matter. Carbon atoms bond in chains and rings. In every carbon substance, a unique formation of carbon can be produced. 3)Carbon has a wide variety of uses both as pure carbon and carbon compounds. Primarily, it acts as hydrocarbons in the form of methane gas and crude oil. Crude oil can be distilled into gasoline and kerosene. Both substances serve as fuel for warmth, machines, and many others. 4)Carbon is also responsible for forming water, a necessary compound for life. It also exists as polymers such as cellulose (in plants) and plastics. 5)Carbon has a wide variety of uses both as pure carbon and carbon compounds.

It also exists as polymers such as cellulose (in plants) and plastics. Graphite : 1)Graphite is an allotrope of carbon. It means that it is a substance made of pure carbon and is made of only carbon. Other allotropes include diamonds, amorphous carbon, and charcoal. 2)Graphite comes from the Greek word “graphein,” which in English means “to write.” Formed when carbon atoms link with each other into sheets, graphite is the most stable form of carbon. 3)Graphite is soft but very strong. It is resistant to heat and, at the same, a good conductor of heat. Found in metamorphic rocks, it appears as a metallic but opaque substance in a color that varies from dark grey to black. Graphite is greasy, a characteristic that makes it a good lubricant. 4)Graphite is also used as a pigment and a molding agent in glass manufacturing. Nuclear reactors also use graphite as an electron moderator b) process of manufacturing of Carbon and graphite fibers: A precursor material, which is rich in carbon, is subjected to pyrolysis to extract its carbon content. Pyrolysis Pyrolysis: Thermochemical chemical decomposition decomposition of organic organic material material when it is subjected subjected to elevated temperatures, but no oxygen. Through such a process, the precursor organic material breaks down into gases, liquids, and a solid residue which is rich in carbon. Precursor: Precursor: It is a carbonrich chemical chemical compound, com.

1. Could the bailout by the Federal Reserve in 1998 and subsequent closing of the fund in 2000 be seen as a precursor of the 2008 Bear Sterns bailout, Lehman Brothers failure, credit crisis and subsequent bank bailout? 1. Please do some outside research on the LTCM failure. How were Henry Paulson, Jon Corzine, & Warren Buffet involved in the failure? Do you think that the involvement of Mr. Paulson had an impact on his actions as Treasury Secretary in 2008? Solution Multiple questions asked. Question 1 is answered below: Yes, the bailout by the Fed in 1998 and the subsequent closing of fund in 2000 can be seen as the precursor of the 2008 Bear Sterns bailout and credit crisis. The bailout by Fed created a problem of moral hazard. Banks and other commercial institutions started giving out money, in the hopes that they would be saved by Fed in case of failure/panic. With more loans being given out, more loans started being taken up by the consumers, creating an inflated boom like situation in the economy. When the time of repayments came, the bubble burst and the lenders defaulted. This created a situation of panic among the investors, who started taking out money from the US economy. Banks runs spread due to panic, resulting in bank failures and credit crisis..

14. (TCO 1-6) Please select the statement which CORRECTLY links a food preservation method with the appropriate reason(s) (Points : 4) Both salt and sugar preserve food by drawing water out of the plant or animal cells by osmosis. Salting or sugaring essentially dehydrates the food, making it inhospitable to microbes, especially bacteria. Dehydration also dramatically slows the action of enzymes that would otherwise degrade the food. Drying food, whether in the sun, in ovens, or in modern freeze drying involving vacuums, removes water, making a food inhospitable to many microorganisms and slows its chemical deterioration. Cooling food whether historically in a cellar, cave, cold running stream, or “Ice-House”, or in modern day refrigerators and freezers slows (or virtually stops in the case of freezing) a bacterium’s metabolism, becoming less able to multiply or produce toxins. In industrial canning ,the food to be canned is sorted, and any spoiled food is removed; the food is washed; the food is parboiled or scalded to stop enzymatic processes and kill microorganisms on the food’s surface; cans are filled and heated, air is siphoned out, and they are sealed; the sealed cans are heated to a very high temperature by steam under pressure and then cooled in a water bath. In irradiation, foods are rid of most pathogenic microbes by gamma rays or other forms of radiation, while frozen foods remain frozen and raw foods stay raw through the process. All of the above correctly link a food preservation method with the appropriate reason(s). Solution All the above correctly link a food preservation method with the appropriate reasons.
