Description Project assignment is to have you do more research on the physical security topic. In theory, everything may look straight forward, however, in real life it might not be like that. In this project you will need to do some research and find an article where physical security has failed. It can be a server room breach, it can be a data center breach, and any scenario that physical security has failed would be your subject. 1. Find an article (from a reputable magazine or link) describing where physical security has failed. 2. Submit a review of this article. Propose a possible change in that organization’s physical security that could have prevented the breach/failure for that scenario. What do you think would have prevented the incident? 3. Submit at least 2 but no more than 3 pages double spaced, APA style MS Word document. 4. No photos or graphs. 5. Reference all sources used.
Description my deadline is 36 hours I need a very competent (several tutors on this here failed my assignments and got bad grade and just wasted my money) in STRUCTURAL EQUATION MODELING. Please, if you are not very very very competent and very familiar with such subject, do not write me you can do the assignment. For first assignment (once I give the data necessary), the tutor must be able to: A) Estimate the three equations of the model, and place the standardized slopes, unanalyzed correlations, and error coefficients on the appropriate lines. Construct the diagram. B) Compute and report the direct, indirect, and total causal effects of each variable C) Test the null hypothesis that this model provides an acceptable fit to the data. Use a likelihood ratio test. More details below I attached the assignment to do. It is a graduate level Doctoral class. Please, only if you are very competent with the subject and you know you will do the assignment PERFECTLY (A+++grade). I will have several assignments that I will have to do, therefore if I see you able to give me A+++ grade, I will always rely on you for my future assignments.
Description 2.1. Using the layer models in Figure2.12, describe the ordering and delivery of a pizza,indicating the interactions at each level. 2.2 The French and Chinese prime ministers need to come to an agreement by telephone, but neither speaks the other’s language. Further, neither has on hand a translator that can translate to the language of the other. However,both prime ministers have English translators on their staffs. Draw a diagram similar to Figure 2.12 to depict the situation, and describe the interaction and each level. b. Now suppose that the Chinese prime minister’s translator can translate only into Japanese and that the French prime minister has a German translator available. A translator between German and Japanese is available in Germany. Draw a new diagram that reflects this arrangement and describe the hypothetical phone conversation 2.3 List the major disadvantages with the layered approach to protocols. 2.4 Two blue armies are each poised on opposite hills preparing to attack a single red army in the valley.The red army can defeat either of the blue armies separately but will fail to defeat both blue armies if they attack simultaneously.The blue armies communicate via an unreliable communications system (a foot soldier).The commander with one of the blue armies would like to attack at noon. His problem is this: If he sends a message to the other blue army, ordering the attack, he cannot be sure it will get through. He could ask for acknowledgment, but that might not get through. Is there a protocol that the two blue armies can use to avoid defeat? 2.5 A broadcast network is one in which a transmission from any one attached station is received by all other attached stations over a shared medium. Examples are a bus-topology local area network, such as Ethernet, and a wireless radio network.Discuss the need or lack of need for a network layer (OSI layer 3) in a broadcast network. 2.6 In Figure 2.2, exactly one protocol data unit (PDU) in layer N is encapsulated in a PDU at layer (N – 1). It is also possible to break one N-level PDU into multiple(N – 1)-level PDUs (segmentation) or to group multiple N-level PDUs into one(N – 1)-level PDU (blocking). a. In the case of segmentation,is it necessary that each (N – 1)-level segment contain a copy of the N-level header? b. In the case of blocking, is it necessary that each N-level PDU retain its own header, or can the data be consolidated into a single N-level PDU with a single N-level header? 2.7 A TCP segment consisting of 1500 bits of data and 160 bits of header is sent to the IP layer,which appends another 160 bits of header.This is then transmitted through two networks, each of which uses a 24-bit packet header.The destination network has a maximum packet size of 800 bits. How many bits, including headers, are delivered to the network layer protocol at the destination? 2.8 Why is UDP needed? Why can’t a user program directly access IP? 2.9 IP,TCP, and UDP all discard a packet that arrives with a checksum error and do not attempt to notify the source.Why? 2.10 Why does the TCP header have a header length field while the UDP header does not? 2.13 A user on a UNIX host wants to transfer a 4000-byte text file to a Microsoft Windowshost.In order to do this,he transfers the file by means of TFTP,using the net ascii transfer mode. Even though the transfer was reported as being performed successfully, the Windows host reports the resulting file size is 4050 bytes,rather than the original 4000 bytes.Does this difference in the file sizes imply an error in the data transfer? Why or why not? 2.15 In order to be able retransmit lost packets, TFTP must keep a copy of the data it sends. How many packets of data must TFTP keep at a time to implement this retransmission mechanism?
Description 8.6 Explain in terms of data link control and physical layer concepts how error and flow control are accomplished in synchronous time division multiplexing. 8.12 Find the number of the following devices that could be accommodated by a T1-type TDM line if 1% of the T1 line capacity is reserved for synchronization purposes. a. 110-bps teleprinter terminals b. 300-bps computer terminals c. 1200-bps computer terminals d. 9600-bps computer output ports e. 64-kbps PCM voice-frequency lines How would these numbers change if each of the sources were transmitting an average of 10% of the time and a statistical multiplexer was used? 8.13 Ten 9600-bps lines are to be multiplexed using TDM. Ignoring overhead bits in the TDM frame, what is the total capacity required for synchronous TDM? Assuming that we wish to limit average TDM link utilization to 0.8, and assuming that each TDM link is busy 50% of the time, what is the capacity required for statistical TDM? 8.14 A synchronous nonstatistical TDM is to be used to combine four 4.8-kbps and one 9.6-kbps signals for transmission over a single leased line. For framing, a block of 7 bits (pattern 1011101) is inserted for each 48 data bits. The reframing algorithm (at the receiving demultiplex) is as follows: 1. Arbitrarily select a bit position. 2. Consider the block of 7 contiguous bits starting with that position. 3. Observe that block of 7 bits each frame for 12 consecutive frames. 4. If 10 of the 12 blocks match the framing pattern the system is “in-frame”; if not advance one bit position and return to step 2. a. Draw the multiplexed bit stream (note that the 9.6kbps input may be treated as two 4.8-kbps inputs). b. What is the % overhead in the multiplexed bit stream? c. What is the multiplexed output bit rate? d. What is the minimum reframe time? What is the maximum reframe time? What is the Average reframe time? 8.15 A company has two locations: a headquarters and a factory about 25 km away. The factory has four 300-bps terminals that communicate with the central computer facilities over leased voice-grade lines. The company is considering installing TDM equipment so that only one line will be needed. What cost factors should be considered in the decision? 8.16 In synchronous TDM, the I/O lines serviced by the two multiplexers may be either synchronous or asynchronous although the channel between the two multiplexers must be synchronous. Is there any inconsistency in this? Why or why not? 8.18 For a statistical time division multiplexer, define the following parameters: OH = 40 C = 9.6 kbps C = 9.6 kbps OH = 40, C = capacity of link, bps L = load of data in the frame, bps OH = overhead in a frame, bits F = frame length, bits a. Express F as a function of the other parameters. Explain why F can be viewed as a variable rather than a constant. b. Plot F versus L for and values of 80, 120. Comment on the results and compare to Figure 8.14. c. Plot F versus L for and values of and 8.2 kbps. Comment on the results and compare to Figure 8.14. 8.19 In statistical TDM, there may be a length field. What alternative could there be to the inclusion of a length field? What problem might this solution cause and how could it be solved?

Description For this reading reflection you should find a group of two or three. You each will do an individual Reading Reflection with the same format as before. The addition to this activity is you will then share with your group members your papers collaboratively, assemble a group consensus on which of each group members learning points were most important (you are focusing even more at this point and refining), which Quiz Questions are written the best and establish meaning and then a group essay question with answer. There is no in class time to converse with your group members so you should learn to develop online SKYPE skills, set up a google docs or a Dropbox share folder or however you design it to work for your group. You will rotate group lead each week so one person isn't doing all the collation of learning points, QQsand Essay questions every week. This reading reflection will begin at Chapter 7 (starting Principle 1: Base Management Decisions on Long Term..... in the Toyota Way Book) The individual RRs will be due here and I will open an assignment link for the group Reflection in another assignment. The individual RRs are due on Sunday nights at Midnight and the TA (Team Assignment) reflections will be due on Mondays at Midnight. Those are the deadlines, you will have plenty of time during the week to make this happen.
Description part 1 : Write a 250 word essay on this topic: “Why is it Important for a Safety Manager to Know the Differences Between an Employee and an Independent Contractor Particularly at the Construction Site?” Why this knowledge is important to the employer? (Hint: an independent contractor may claim he or she is an employee after an incident-- what would that change as far as the employer's obligations under OSHA?) part 2: In this assignment you will use the CFR and internet to locate and analyze letters of interpretation. Locate two (2) letters of interpretation about fall protection on residential roofing projects. In 25 -50 words each, describe the issue inquired about by the employer and OSHA's response. part 3: In this assignment you will use the CFR and internet to locate and analyze Review Commission findings. Students will locate two (2) cases from the OSHRC website and in 25-50 words, describe the central issue on the case which is decided by the OSHRC panel or judge. part 4 : Using the sample incident investigation checklist provided, determine three (3) places on the sample report where new items can be added or redundant items eliminated. We are not using the form to investigate an incident-- we are only using the form to make the process better by editing the sample form itself. part 5 : Download the attached file "SAFM 470 Abstract Protocol." In a maximum of three pages, prepare an abstract (summary of key points) on Subpart M - Fall Protection (which will be discussed in depth next week) according to the guidelines included in the abstract protocol
