solutions for assignment5
Chapter 5+6+8 AssignmentsP5.Consider the 5-bit generator, G= 10011, and suppose that D has the value 1010101010. What is the value of CRC?Solution:If we divide 10011 into 1010101010 0000, we get 1011011100, with a remainder of R=0100.P21. Suppose nodes A and B are on the same 10Mbps Ethernet bus, and the propagation delaybetween the two nodes is 245 bit times. Suppose A and B send frames at the same time, the frames collide, and then A and B choose different values of K in the CSMA/CD algorithm. Assuming no other nodes are active, can the retransmissions from A and B collide? For our purposes, it suffices to work out the following example. Suppose A and B begin transmission at t =0 bit times. They both detect collisions at t =245 bit times. They finish transmitting a jam signal at t = 245 + 48 = 293 bit times. Suppose K A =0 and K B = 1. At what time does B schedule its retransmission? At what time does A begin transmission? (Note: The nodes must wait for an idle channel after returning to Step 2 -- see protocol.) At what time does A's signal reach B? Does B refrain from transmitting at its scheduled time?Solution:Because A's retransmission reaches B before B's scheduled retransmission time (805+96), B refrains from transmitting while A retransmits. Thus A and B donot collide. Thus the factor 512 appearing in the exponential backoff algorithm is sufficiently large.P23. Suppose four nodes, A, B, C, and D, are all connected to a hub via 10Mbps Ethernet cables.The distances between the hub and these four nodes are 300m, 400m, 500m, and 700m, respectively. Recall that the CSMNCD protocol is used for this Ethernet. Assume that the signal propagation speed is 2*108m/sec.a. What is the minimum required frame length?b. If all frames are 1500 bits long, find the efficiency of this Ethernet.Solution:a). minimum required frame length is given by2*d prop* BW=2*(500+700)/( 2 108) * 10 * 106=120 bits.There is no maximum required packet length.b). Efficiency is given by1/(1+5* d prop/ d trans) =1/(1+5*120/2/1500 )=0.83P37. In this problem, you will put together much of what you have learned about Internetprotocols. Suppose you walk into a room, connect to Ethernet, and want to download a web page. What are all the protocol steps that take place starting from powering on your PC to getting the web page? Assume there is nothing in our DNS or browser caches when you power on your Pc. (Hint: the steps include the use of Ethernet, OHCP, ARP, ONS, TCP, and HTTP protocols.) Explicitly indicate in your steps how you obtain the IP and MAC addresses of a gateway router.Solution:(The following description is short, but contains all major key steps and key protocols involved.)Your computer first uses DHCP to obtain an IP address. You computer first creates a special IP datagram destined to 255.255.255.255 in the DHCP server discovery step, and puts it in a Ethernet frame and broadcast it in the Ethernet. Then following the steps in the DHCP protocol, you computer is able to get an IP address with a given lease time.A DHCP server on the Ethernet also gives your computer a list of IP addresses of first-hop routers, the subnet mask of the subnet where your computer resides, and the addresses of local DNS servers (if they exist).Since your computer’s ARP cache is initially empty, your computer will use ARP protocol to get the MAC addresses of the first-hop router and the local DNS server.Your computer first will get the IP address of the Web page you would like to download. If the local DNS server does not have the IP address, then your computer will use DNS protocol to find the IP address of the Web page.Once your computer has the IP address of the Web page, then it will send out the HTTP request via the first-hop router if the Web page does not reside in a local Web server. The HTTP request message will be segmented and encapsulated into TCP packets, and then further encapsulated into IP packets, and finally encapsulated into Ethernet frames. Your computer sends the Ethernet frames destined to the first-hop router. Once the router receives the frames, it passes them up into IP layer, checks its routing table, and then sends the packets to the right interface out of all of its interfaces.Then your IP packets will be routed through the Internet until they reach the Web server.The server hosting the Web page will send back the Web page to your computer via HTTP response messages. Those messages will be encapsulated into TCP packets and then further into IP packets. Those IP packets follow IP routes and finally reach your first-hop router, and then the router will forward those IP packets to your computer by encapsulating them into Ethernet frames.Additional 1: Please answer the following question after reading Chapter 6 and referring tothe ftp:///chapt6.pdf . What are MAC methods for WiFi, Bluetooth, WiMax and Cellular network respectively? What are RDT approaches for WiFi, Bluetooth, WiMax and Cellular network respectively? error detection + retransmisstion or error correction?Solution:The following table summarizes the wireless MAC and RDT technologies. Each needs to be explained in detail.Additional 2:Why WiFi can’t CSMA/CD?Solution:Because Collisions Detection is difficult for WiFi:∙hidden terminal problem !∙difficult to sense because of fading∙Most radios are half duplexAdditional 3: Please explain how public key cryptography RSA is used in email security protocol: PGP (Pretty Good Privacy). Please refer to Chapter 8Solution:Step 1: Calculate hash (MD5) of message H(m). => you’ve got the digest of the messageStep 2: Encrypt H(m) with Alice’s private key => you’ve got Alice’s signature.Step 3: Append signature to text, then encrypt it with shared key Ks.Step 4: Encrypt shared key Ks with Bob’s public key, then append to the cipher text of step 2 => Bob can get the Ks.Step 5: The result message of step 4 is converted to base64 and be put into an RFC 822 body and be expected to arrive unmodified.D2 (don’t submit) Many of the functions of an adapter can be performed in software that runs onthe node's CPU. What are the advantages and disadvantages of moving this functionality from the adapter to the node?。

What are purchasing activities and how are they different from procurement?Purchasing activities include identifying vendors, evaluating vendors, selecting specific prod ucts, placing orders, and resolving any issues that arise after receiving the ordered goods or servic es.Procurement generally includes all purchasing activities, plus the monitoring of all elements of purchase transactions. It also includes the job of managing and developing relationships with key suppliers.97. What is the difference between an indirect connection and a direct connection?Direct connection requires each business in the network to operate its own on-site EDI transla tor computer. These EDI translator computers are then connected directly to each other using mod ems and dial-up telephone lines or dedicated leased lines.With an indirect connection, the trading partners pass messages through the V AN instead of c onnecting their computer directly to each other.98. What are the advantages of using Internet technologies in supply chain management? Suppliers can:Share information about customer demand fluctuations.Receive rapid notification of product design changes and adjustments.Provide specifications and drawings more efficiently.Increase the speed of processing transactions.Reduce the cost of handling transactions.Reduce errors in entering transaction data.Share information about defect rates and types.99. What is the difference between direct and indirect materials?Direct materials are those materials that become part of the finished product in a manufacturi ng process. Indirect materials are all other materials that the company purchases, including factory supplies such as sandpaper, hand tools, and replacement parts for manufacturing machinery.100. What are the advantages of using a value-added network?Advantages of using V ANs are as follows:Users need to support only the V AN’s communications protocol instead of many possible pro tocols used by trading partners.The V AN records message activity in an audit log. This V AN audit log becomes an independe nt record of transactions, and this record can be helpful in resolving disputes between trading partners.The V AN can provide translation between different transaction sets used by trading partners.The V AN can perform automatic compliance checking to ensure that the transaction set is in t he specified EDI format.。

Assignment 5
Hidden Markov Model in Music Information RetrievalMUMT 611, March 2005Assignment 5Paul KolesnikIntroduction to HMMHidden Markov Model (HMM) is a structure that is used to statistically characterize the behavior of sequences of event observations. By definition, HMM is “a double stochastic process with an underlying stochastic process which is not observable, but can only be observed through another set of stochastic process that produces the sequence of observed symbols” (Rabiner and Huang 1986).The main idea behind HMM is that any observable sequence of events can be represented as a succession of states, with each state representing a grouped portion of the observation values and containing its features in a statistical form. The HMM keeps track of what state the sequence will start in, what state-to-state transitions are likely to take place, and what values are likely to occur in each state. The corresponding model parameters are an array of initial state probabilities, a matrix of state-to-state transitional probabilities, and a matrix of state output probabilities. The two basic HMM model types are an ergodic model, where any-to-any state transitions are allowed, and a left-to-right model, where state transitions can only take place to the state itself or to the subsequent state.HMM delas with three basic problems—recognition, uncovering of states and training. The recognition problem can be formulated as: “given an observation sequence and a Hidden Markov Model, calculate the probability that the model would produce this observation sequence”. The uncovering of states problem is: “given an observation sequence and a Hidden Markov Model, calculate the optimal sequence of states that would maximize the likelihood of the HMM producing the observation”. The training problem states: “given an observation sequence (or a set of observation sequences and a Hidden Markov Model, adjust the model parameters, so that probability of the model is maximized”. Through the algorithms used to solve those problems (Forward-Backward, Viterbi and Baum-Welch algorithms), an HMM can be trained with a number of observations, and then be used either for calculation of probability of an input sequence, or for identification of states in the input sequence interpreted by the HMM.Overview of WorksThis section provides an overview of the works presented at the International Symposium on Musical Information and Retrieval (ISMIR) that dealt with HMM-based systems.A publication by Batlle and Cano (2000) describes a system that uses HMMs to classify audio segments. Using the system, audio files are automatically segmentated into abstract acoustic events, with similar events given the same label to be used for training of the HMMs. THe system is applied to classification of a database of audio sounds, and allowsfast indexing and retrieval of audio fragments from the database. During the initial stage of the process, mel-cepstrum analysis is used to obtain feature vectors from the audio information, which are then supplied to an HMM-based classification engine. Since traditional HMMs are not suited for blind learning (which is the goal of this system, as there is no prior knowledge of the feature vector data), competitive HMMs (CoHMMs) are used instead. CoHMMs differ from HMMs only in training stage, whereas the recognition procedure is exactly the same for both,A work by Durey and Clements (2001) deals with a melody-based database song retrieval system. The system uses melody-spotting procedure adopted from word spotting techniques in automatic speech recognition. Humming, whistling or keyboard are allowed as input. According to the publication, the main goal of the work was to develop a practical system for non-symbolic (audio) music representation. The word/melody-spotting techniques involve searching for a data segment in a data stream using HMM models. Left-to-right, 5-state HMMs are used to represent each available note and a rest. As part of the preprocessing process, frequency and time-domain features are used for extraction of feature vectors. The system records the extracted feature vectors for all of the musical pieces and stores them in a database. Once an input query is received, it constructs an HMM model from it, and runs all of the feature vectors from the songs in the database through the model using the Viterbi state uncovering process. As a result, a ranked list of melody occurrences in database songs is created, which allows identifying the occurrence of the melodies within the songs.A publication by Jin and Jagadish (2002) describes a new technique suggested for HMM-based music retrieval systems. The paper describes traditional MIR HMM techniques as effective but not efficient, and suggests a more efficient mechanism to index the HMMs in the database. In it, each state is represented by an interval / inter onset interval ratio, and each transition is transformed into a 4-dimensional box. All boxes are inserted into an R-tree, an indexing structure for multidimensional data, and HMMs are ranked by the number of boxes present in the search tree. The most likely candidates from the R-tree are selected for evaluation of the HMMs, which uses the traditional forward algorithm.A publication by Orio and Sette (2003) describes an HMM-based approach to transcription of musical queries. HMMs are used to model features related to singing voice. A sung query is considered as an observation of an unknown process—the melody the user has in mind. A two-level HMM is suggested for pitch tracking: an event-level (using pitches as labels), and audio-level (attack-sustain-rest events).A paper by Sheh and Ellis (2003) deals with the system that uses HMMs for chord recognition. An EM (Expectation-Maximization) algorithm is used to train the HMMs, and PCP (Pitch Class Profile) vectors are used as features for the training process. Each chord type is represented by an independent HMM model. According to the publication, the system is able to successfully recognize chords in unstructured, polyphonic, multi-timbre audio.Shifrin and Burmingham (2003) present a system that investigates performance of an HMM-based query-by-humming system on a large musical database. A VocalSearch system, that has been desgined as part of MusArt project, is used on a database of 50000 themes that have been extracted from 22000 songs. The system uses a <delta-pitch / Inter-onset Interval ratio> pair as parameters for the feature vectors supplied to the HMMs. The work compares perfect queries with imperfect queries that have simulated insertions and deletions added to the sequences. Some of the trends discovered as a result of the work are: longer queries have a positive effect on evaluation performance, but all experiments show an early saturation point where performance does not improve with query length. The system performed well with imperfect queries on a large database.BibliographyBatlle, E., and P. Cano. 2000. Automatic segmentation for music classification using Competitive Hidden Markov Models.

引力模型（Gravity Model）是应用广泛的空间相互作用能力模型，即用来分析和预测空间相互作用能力的数学模型。
该模型已经被广泛应用到各种学科领域中，其中比较常见的是国际贸易学说。
在国际贸易学说中，引力模型是指两个国家之间的单项贸易流量与其各自的经济规模（GDP）成正比，与两个国家之间的距离成反比。
边界的存在对渗流场的等势线分布、流线分布和井产量等都会产生影响，通常将这种影响称为边界效应。
一般来说，边界是众多信息汇聚的地方，它具有异质性，是变化的所在,容易产生特殊的现象，受到人们的关注，这就是通常所说的边界效应。
从人的心理出发，人类容易对异质的东西发生兴趣，而对于同质的东西产生厌倦和腻烦。
区位主体是指与人类相关的经济和社会活动，如企业经营活动、公共团体活动、个人活动等。
区位主体在空间区位中的相互运行关系称为区位关联度。
区位关联度影响投资者和使用者的区位选择。
一般来说，投资者或使用者都力图选择总成本最小的区位，即地租和累计运输成本总和最小的地方。
区位理论是关于人类活动的空间分布及其空间中的相互关系的学说。
具体地讲，是研究人类经济行为的空间区位选择及空间区内经济活动优化组合的理论。
次区域经济合作是相对于区域经济合作而言的，指若干国家和地区接壤地区之间的跨国界的自然人或法人，基于平等互利的原则，在生产领域内，通过各种生产要素的流动而开展的较长时期的经济协作活动。
从经济发展的角度看，其实质就是生产要素在“次区域”这个地缘范围内的趋向自由化的流动，从而带来生产要素的有效配置和生产效率的相应提高，主要表现为在这个地缘范围内的贸易和投资自由化，因而，在经济范畴上，它属于区域经济一体化范畴。
边界是影响跨境次区域经济合作的重要因素。
最早的研究已经证实，边界会阻碍资本、劳动力、商品等跨境自由流动，很多学者运用各种方法研究边界对跨边界经济行为的影响，其中运用引力模型分析区域经济一体化的边界效应是最主要的方式。
传统的区位理论最早对边界效应进行了阐述，Giersch（1949）等人认为边界限制了商品的物理流动性，边界地区在发展中是不利的。
Lopes（2003）、Rose 和van Wincoop（2001）分别认为较高的运输成本和不同的货币是导致两国边界效应较高的主要因素。
另外在实证分析中，McCallum （1995）、James E. Anderson 和Eric van Wincoop（2001）、Peter Huber（2011）、Coughlin 和Novy（2013）等利用引力模型以及加拿大与美国之间、欧盟之间以及美国内部的贸易数据，验证了边界效应的显著影响。
国内还有很多学者研究中国对外贸易的边界效应。
张玉新（2012）重点关注了跨境次区域经济合作中中国沿边地方政府的行为。
洪昆辉（2004）王胜今（2006）、倪超军（2008）等人分别提出推进云南、广西参与大湄公河和东盟次区域合作、中国东北三省参与图们江和东北亚次区域合作、新疆参与中亚区域经济合作的战略和政策。
总体来说，目前对中国沿边地区的研究大多从战略和政策角度出发，没有对中国沿边地区对外经济一体化的边界效应进行科学验证和详细说明。
鉴于此，本文主要利用城市数据研究我国沿边地区跨境次区域合作过程中面临的边界效应，在实证分析中，针对沿边城市大多是内陆城市、对外运输基本靠陆路运输的特点，侧重用包括陆路、海运等多种距离测算方法更好地衡量沿边实际运输成本，在数据允许范围内对引力模型进行修正。
同时充分考虑沿边城市的地理区位、基础设施便利度、城市行政级别、内部和外部经济增长等方面影响，在此基础上提出相应对策建议。
