...10 Effective Teaching Techniques: How to capture and maintain your student in Science and Mathematics. Tip #1: Engage • Engage the students in material that has personal relevance and is meaningful i.e. real life examples and problems Tip #2: Variety • Give the students assignments that involve a variety of learning styles Research with books Technology Hand on Experiments Tip #3: Students Teaching • Provide times when students can teach each other the material within the classroom i.e. group presentations – Leadership – Ownership – Mastery Test #4: Review • Every other day or so, allot 10 minutes at the beginning of each class for students to discuss among themselves what they learned in previous lessons. Tip #5: Reward system • Implement a reward system for students to encourage them to take their learning outside the classroom • Reward students who can apply the material to real life examples • Reward students who improve from test to test • Reward students who engage in group discussions outside of the classroom to discuss ideas on how to use their knowledge to solve problems. Tip #6: Goals • Help students establish short term, self referenced goals at the beginning of the term and have them check up midterm to see if they are still on track to accomplishing their goals Tip #7: Stimulate group work • At the end of each class, present the students with a “challenge for the night” and allow students to work in groups of 3 or 4 to solve...

...11/09/2011 Supermassive Black Holes were first theorized to exist in the 1790’s. John Michell of England and Pierre LaPlace of France independently suggested the existence of an "invisible star." Michell and LaPlace calculated the mass and size — which is now called the "event horizon" — that an object needs in order to have an escape velocity greater than the speed of light. In 1967 John Wheeler, an American theoretical physicist, applied the term "black hole" to these collapsed objects. It wasn’t until the early 1970’s that an intense an intense X-ray source was found in the constellation Cygnus called Cygnus X-1. As the years passed, in the spring of 1972, Cygnus X-1 was identified with a star known by its classification number HDE226868 (which is a radio source). Astronomers have since found convincing evidence for a supermassive black hole in the center of the giant elliptical galaxy M87, as well as in several other galaxies. The discovery is based on velocity measurements of a whirlpool of hot gas orbiting the black hole. In 1994, Hubble Space Telescope data produced an unprecedented measurement of the mass of an unseen object at the center of M87. Based on the kinetic energy of the material whirling about the center (as in Wheeler's dance, see Question 4 above), the object is about 3 billion times the mass of our Sun and appears to be concentrated into a space smaller than our solar system. A supermassive black...

...One genre fits all? Whether you prefer a romance, an action or a thriller, Science Fiction seems to fit it all in but still have its own unique identity. Is this why it appeals to so many? As Reported By ReJohnson. Looking around at movie advertisements shown on billboards, bus stands and television, it’s hard to miss the growing popularity of science fiction movies and books in modern society. Though still not as popular as genres such as Action and romance, many people have found an interest and love for science fiction. Over the past decade, there have been over 300 Science Fiction movies released. Statistics show that 5 in every 10 movies released in today’s society is science fiction. Many of them hitting the top ten list and have been nominated or have won major awards (e.g. Avatar which won 3 Oscars, the Golden Globe etc.). So why does it appeal to modern day audiences? It seems that in modern society, no matter how you look at it, Science fiction is a genre that can appeal to each individuals taste making it appealing to almost anyone. Though it is mainly based around an imagined future and scientific and technological advances, directors and producers have created a scale as to how ‘hard’ or ‘soft’ the science fiction movie is. While Hard Science Fiction focuses mostly on the speculation of the future as seen in the award- winning Matrix, Soft science Fiction focuses more on the entertainment of the audience and allowing them to escape from reality as seen in the...

...Lab Research Report 1: Procedures in the Physical Sciences Robert Hugee Professor Brian McCann SCI110024VA016-1134-001: Introduction To Physical Science April 25, 2013 One of the underlying challenges in astronomy measurement is the determination of precise distances. Without a knowledge of its distance, the size of an observed object in space would remain nothing more than an angular diameter, and the brightness of a star could not be converted into its true radiated power, or luminosity .astronomy. (2013). Direct measurement of the wavefunction had also long been deemed impossible because of the key tenet of the uncertainty principle. University of Rochester (2013, March 3). Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond those...

...well as information I had received from my own experience. I concluded that she is outspoken, talented, and extremely extremely stubborn. Her challenge seemed to begin her senior year of highschool that she has lost her motivation for school. “I’m so lazy- now that I I’m highschool and it's not a traditional high school I don't care if I learn or not”. She refers to our high school in where they teach the students to create our own research questions to learn the school standards. “Before I didn't mind school I did really good, but I felt like I didn't get to learn how I want to learn or I didn't have someone to really guide me in what I had to learn when I got here so I started to get bored and lost interest, like my bookbag is a blackhole you will get sucked in with the mess in there” Looking at learning concepts made around Ivan Pavlov dog experiment, its can be said that Yanci has gone through extinction with being motivated. Extinction is when a conditioned response has disappeared (gone in extinction) creating the person to forget what the response was suppose to be. Before she was accustomed to going to school and not having to create her own research guide in order to learn and understand a certain concept. Now that she is placed in a school in where the teacher is giving her this freedom in which she never experience; to move around the classroom and get our own materials to learn, she has forgotten how to have the mindset of a student.

For instance, network #1 had intrusive access via a Microsoft ISS web server to cmd.exe, which allowed complete access to the system. This was achieved through a buffer overflow attack against IIS. As such, the administrator of this network should ensure that all systems are fully patched in order to avoid known exploits. For network #2, an exploit via phpBB enabled access to the system. Network #3, “EXPLOI~1.RTF”, which a user must have downloaded, was executed, opening up a backdoor into the system. Unfortunately, as outlined in my conclusion, an in-depth analysis of this data was aborted partly due to time mismanagement and a very large course load for the term.

A mo¬bile adhoc network consists of mobile nodes that can move freely in an open environment. Communicating nodes in a Mobile Adhoc Network usually seek the help ofother intermediate nodes to establish communication channels.

Therefore, some novel solutions are required to make Mobile Adhoc Network secure. 1 Introduction A Mobile Adhoc Network is a group of wireless mo¬bile computers in which nodes cooperate by forwarding packets for each other to allow them to communicate beyond direct wireless transmission range. Application such as military excercises, disaster relief, and mine site operation may benefit from adhoc networking, but secure and reliable communication is a necessary pre¬requisite for such applications. MANETS are more vulnerable to attacks than wired networks due to open medium, dynamically changing network topology, cooperative algorithms, lack of cen-tralized...

...Fall 2006, Syracuse University Lecture Notes for CIS/CSE 758: Internet Security Routing Protocols (1) Introduction Static routing versus dynamic routing Static routing Fixes routes at boot time Useful only for simplest cases Dynamic routing Table initialized at boot time Values inserted/updated by protocols that propagate route information Necessary in large internets Routing with partial information The routing table in a given router contains partial information about possible destinations For the unknown destinations, forward them to the default router. Potential problem: some destinations might be unreachable. Original Internet and the problem if the core routers are allowed to have default routes. Core routing architecture with single backbone. Assumes a centralized set of routers that know all possible destinations in an internet. Non-core routers use the core routers as their default routers. Work best for internets that have a single, centrally managed backbone. Inappropriate for multiple backbones. Disadvantage Central bottleneck for all traffic Not every site could have a core router connected to the backbone: how do they get routing information? No shortcut route possible: non-core routers always forward their traffic to the default routers even though another core router provides a better route. This is because the noncore routers do not know which one is better without full knowledge of all possible destinations...

...NETWORKING Networking Paul F. Scheelk NTC/360 Network and Telecommunications Concepts Instructor: Anthony Bruno University of Phoenix 1. What is the range of usable IP addresses for the following IP subnet? What is the broadcast address for the subnet? 10.150.100.96/27 The range of usable IP addresses is 10.150.100.97 – 10.150.100.126. The first and last addresses are not usable and cannot be assigned to hosts as one is used as the broadcast address, 10.150.100.127 and 10.150.100.96 is the address for the sub network. When initially determining the usable addresses the /27 provides the information that the first 27 bits are network and the remaining 5 are host addresses. The subnet address would be 255.255.255.224. 2. Describe and explain the difference between circuit bandwidth and network throughput. Focus on networking. Communication networks using Ethernet or other protocols distinguish throughput as the average rate of successful packet delivery over a communication channel. The information is passed over a physical or logical link such as Cat5, 5A or 6 or media such as coax and fiber. It is also measured over a wireless network. It is usually measured in bits per second (bit/s or bps), and/or data packets per second or time slot. Throughput is the actual speed that the data is being transmitted. Bandwidth on the other hand is the maximum speed in which packets can be sent or received. Bandwidth is almost always a higher rate than throughput. 3. Research...

The security of such network is a major concern. To improve the security of such network, technique proposed here is securing routing protocol AODV through the use of Symmetric Encryption algorithm AES. This secures the data as well as preserves the confidentiality. Further future work to be carried as of node authentication using IP address and using the AODV routing protocol and digital signature scheme. Keywords-- Mobile ad-hoc, symmetric encryption algorithm, confidentiality, AODV, Digital signature, IP address The nodes involved in a MANET should collaborate amongst themselves and each node acts as a relay as needed, to implement functions e.g. security and routing. C] Multihop Routing: Basic types of ad hoc routing algorithms can be singlehop and multihop, based on different link layer attributes and routing protocols. Single-hop MANET is simpler than multihop in terms of structure and implementation, with the cost of lesser functionality and applicability. When delivering data packets from...
