Explain and discuss 4G wireless communications and their advantages. Solution 4G stands for fourth-generation wireless, it is the stage of broadband mobile communications that will supercede the third generation 3G. Explanation- Fourth generation wireless system is a packet switched wireless system with wide area coverage and high throughput. It is designed to be cost effective and to provide high spectral efficiency . The 4g wireless uses Orthogonal Frequency Division Multiplexing (OFDM), Ultra Wide Radio Band (UWB),and Millimeter wireless. Data rate of 20mbps is employed. Mobile speed will be up to 200km/hr.The high performance is achieved by the use of long term channel prediction, in both time and frequency, scheduling among users and smart antennas combined with adaptive modulation and power control. Frequency band is 2-8 GHz. it gives the ability for world wide roaming to access cell anywhere. This new generation of wireless is intended to complement and replace the 3G systems. Accessing information anywhere, anytime, with a seamless connection to a wide range of information and services, and receiving a large volume of information, data, pictures, video, and so on, are the keys of the 4G infrastructures. The future 4G infrastructures will consist of a set of various networks using IP (Internet protocol) as a common protocol so that users are in control because they will be able to choose every application and environment. Based on the developing trends of mobile communication, 4G will have broader bandwidth, higher data rate, and smoother and quicker handoff and will focus on ensuring seamless service across a multitude of wireless systems and networks. The key concept is integrating the 4G capabilities with all of the existing mobile technologies through advanced technologies. Application adaptability and being highly dynamic are the main features of 4G services of interest to users. These features mean services can be delivered and be available to the personal preference of different users and support the users\' traffic, air interfaces, radio environment, and quality of service. Connection with the network applications can be transferred into various forms and levels correctly and efficiently. The dominant methods of access to this pool of information will be the mobile telephone, PDA, and laptop to seamlessly access the voice communication, high-speed information services, and entertainment broadcast services. The fourth generation will encompass all systems from various networks, public to private; operator-driven broadband networks to personal areas; and ad hoc networks. The 4G systems will interoperate with 2G and 3G systems, as well as with digital (broadband) broadcasting systems. In addition, 4G systems will be fully IP-based wireless Internet. This all-encompassing integrated perspective shows the broad range of systems that the fourth generation intends to integrate, from satellite broadband to high altitude platform to cel.

TeliaSonera was the first operator in the world to commercially launch 4G. It was in late 2009, in the city centres of Stockholm and Oslo. 4G is the short term for fourth-generation wireless. It is still a research lab standard , the stage of broadband mobile communications that will supersede the third generation (3G). It is expected that end-to-end IP and high-quality streaming video will be among 4G's distinguishing features. A 4G system will be able to provide a comprehensive IP solution where voice , data and streamed multimedia can be given to the users on “ Anytime Anywhere ” basis and higher data rates than the previous generations. It will be a fully IP based integrated system capable of providing between 100 Mbps to 1 Gbps in both indoor and outdoor with premium quality and high security. It is going to be launched in the year 2010.

Hi please complete the following with detailed working out Find the eigenvalues of C1 C1 C1 C1 C2 C3 C3 C3 C3 cn cn Hint: You may find that the identity A2 (c1 c2 cm) is useful. Solution COORDINATES, EIGENVALUES, AND EIGENVECTORS 1. Review of coordinates 1.1. The standard basis. The standard basis for R n is the basis E = {e1, e2, . . . en}, where ej is the vector with 1 in the j-th position and zeros elsewhere. 1.2. Coordinates with respect to a basis. Let B = {v1, v2, . . . vn} be a basis for R n . We know that for each vector x R n there are unique scalar “coordinates” c1, c2, . . . cn such that (1.1) x = c1v1 + c2v2 + . . . + cnvn We call the vector c R n having coordinates c1, c2 . . . cn the “coordinate vector” of x with respect to the basis B, and denote it by [x]B. 1.3. First examples. (a) [x]E = x for each x R n . (b) For any basis B = {v1, v2, . . . vn} of R n : [vj ]B = ej (1 j n). (c) [0]B = 0 for any basis B (the zero vector has the same representation with respect to any basis. 1.4. Matrix calculation of coordinates. Letting B = {v1, v2, . . . vn} be a basis for R n we can rewrite equation (1.1) in matrix form as (1.2) x = V [x]B where V is the matrix having the vector vj for its j-th column, i.e. V = [v1, v2, . . . vn]. . 1 2 EIGENVALUES/EIGENVECTORS V is invertible because its columns are linearly independent (see, for example, Summary 3.2.9(v) of our textbook, pp. 119–120), so we can compute the B coordinate representation of any vector x R n by solving (1.2) for [x]B: (1.3) [x]B = V 1x For example, if in R 2 we take B = {v1, v2} to be our basis, where v1 = 1 3 and v2 = 2 5 , then V = 1 2 3 5 and V 1 = 5 2 3 1 . Suppose, for instance, that x = 1 1 . Then [x]B = V 1x = 5 2 3 1 1 1 = 7 4 More generally, if x = x1 x2 is any vector in R n then the same calculation shows that [x]B = 5x1 + 2x2 3x1 x2 . 1.5. The matrix of a linear transformation with respect to a basis. Recall that each n × n matrix induces a linear transformation T : R n R n by means of matrix multiplication: (1.4) T(x) = Ax (x R n ). We refer to A as the “standard matrix” for T. The lesson of what’s to follow is that it’s not always the best matrix for T! For a basis B = {v1, v2, . . . vn} for R n we define (1.5) [T]B = [[T(v1)]B, [T(v2)]B . . . [T(vn)]B] , i.e. [T]B is the matrix that has the B-coordinate representation of T(vj ) as its j-th column (1 j n). We call [T]B the matrix of T with respect to the basis B. 1.6. Example: B = E, the standard basis. In this case [T]B = [Ae1, Ae2, . . . Aen], the “standard matrix” for T. EIGENVALUES/EIGENVECTORS 3 1.7. Geometric examples in R 2 . In this next group of examples, L is a line through the origin in the direction of a non-zero vector v R 2 , and w is a non-zero vector perpendicular to v. We take as our basis for R 2 , not the standard one, but instead B = {v, w}. (a) Suppose T : R 2 R 2 is the transformation of orthogonal projection onto L. Then T(v) = v and T(w) = 0, so [T]B = [[T(v)]B, [T(w)]B] = [[v]B, [0]B] = .

Draw and describe a module of the cross-cultural communication process, and provide an hypothetical example from advertising or public relations(PR) to explain how such communication may fail, improve and succeed Draw and describe a module of the cross-cultural communication process, and provide an hypothetical example from advertising or public relations(PR) to explain how such communication may fail, improve and succeed Solution All communication is social - it draws on ways we have figured out how to talk and give nonverbal messages. We don\'t generally impart a similar route from everyday, since factors like setting, singular identity, and state of mind interface with the assortment of social impacts we have disguised that impact our decisions. Communication is intuitive, so a vital impact on its adequacy is our association with others. Do they hear and comprehend what we are endeavoring to state? It is safe to say that they are listening admirably? Is it true that we are listening admirably accordingly? Do their reactions demonstrate that they comprehend the words and the implications behind the words we have picked? Is the state of mind positive and responsive? Is there trust amongst them and us? Are there contrasts that identify with ineffectual communication, unique objectives or interests, or on a very basic level diverse methods for seeing the world? The responses to these inquiries will give us a few signs about the viability of our communication and the straightforwardness with which we might have the capacity to travel through clash. The test is that even with all the cooperative attitude on the planet, miscommunication is probably going to happen, particularly when there are critical social contrasts between communicators. Miscommunication may prompt clash, or disturb struggle that as of now exists. We make - whether it is obvious to us or not - very unique importance of the world, our places in it, and our associations with others. In this module, culturally diverse communication will be illustrated and exhibited by cases of thoughts, states of mind, and practices including four factors: • Time and Space • Fate and Personal Responsibility • Face and Face-Saving • Nonverbal Communication As our nature with these distinctive beginning stages builds, we are developing social familiarity - consciousness of the ways societies work in communication and strife, and the capacity to react successfully to these distinctions. Time and Space Time is a standout amongst the most focal contrasts that different societies and social methods for getting things done. In the West, time has a tendency to be viewed as quantitative, estimated in units that mirror the walk of advance. It is intelligent, successive, and exhibit engaged, moving with incremental assurance toward a future the self image can\'t contact and a past that isn\'t a piece of now. In the East, time feels like it has boundless coherence, a disentangling as opposed to a strict limi.

Discuss the reasons why visions fail. What steps can be implemented to help successfully achieve a vision? Solution Vision is nothing but the summary of the organization\'s goals and objectives. Vision leads to successful change in an organization. Vision helps in identifying whether the particular change is appropriate for the organization or not. It is the organizational declaration as to what the organization wants to achieve as their mid-term or long-term goals. These are generally descriptive and inspirational to accomplish the goals. Vision often fail because The steps that can be implemented to help successfully achieve a vision are: -.

Describe the original purpose of the Clean Air Act Policy of 1963. Explain what the Amendments of 1970 and 1990 added to this policy. What were the benefits and disadvantages of these amendments? Should the policy be amended again to reflect current environmental / economic issues and technology innovations. Solution INTRODUCTION AND PURPOSE The Clean Air Act was major legislation passed to control air pollution in the United States. The Act was passed in 1963, but important and major amendments were added to the original Act in 1970 and 1990. This Act implements a comprehensive program for reducing air pollution focusing on the reduction of ambient (that which is present in the open air) and source specific (that which can be traced to identifiable sources, such as factories and automobiles) air pollution. It was a legislation that offered federal research aid, urged the development of state control agencies, and involved the federal government in inter-state pollution issues. More amendments were added to the Act in 1977. They were concerned with states that were not achieving national objectives as to auto emissions and measures to prevent air quality deterioration in areas where the air had previously been clean. This was the federal government’s first active role in clean air policy. But it was the Clean Air Act of 1970 that for the first time granted real power to the federal government instead of the states. AMENDMENT 1970 The 1970 Clean Air Act forms the basis of the U.S. air pollution control policy. It has four major components: i) it put into place National Ambient Air Quality Standards which are intended to protect human health and environment (the Environmental Protection Agency (EPA) developed these standards and they targeted major polluting chemicals); ii) EPA was to establish New Source Performance Standards to determine how much pollution should be allowed by different industries in different regions; iii) The Act specified standards for controlling auto emissions, aiming at reduction of various gases by almost 90 percent; and iv) the law encouraged states to develop plans to achieve these standards and required that those state plans should be approved by EPA. Where any state chose not to form such a plan or did not complete it by a specified date, the EPA can take over administration of the law for that state. The 1970 Act required states to enforce the Cleanliness.. AMENDMENT 1990 The Clean Air Act was last amended in 1990. This amendment addressed environmental issues like acid rain, toxic pollutants, areas still not at regulation standards, and ozone layer depletion. Massive decreases in certain gas emissions were mandated to control acid rain; increased regulation of toxic pollutants; deadlines for the noncompliant areas; and three major chemical contributors to ozone layer depletion were phased out. RESULT A 2017 study found that the Clean Air Act of 1970 led to an over 10 percent reduction in pollution (\"ambient TSP.

7. In many respects metal binding is similar to the binding of a proton. For instance the N- atom of thiocyanate can be protonated to produce (H-NCS). Similarly, protonation of the cyanide anion (CN-) can be observed at the C-atom to produce H-CN. In apparent contrast to this analogy, metal coordination to (NCS) can be observed at either N- or S- atoms (M-NCS and NCS-M) whereas protonation only occurs at the N-atom. Provide an explanation for this behavior. Similarly, why is the cyanide anion only capable of binding metals and protons at the C-atom? Solution SCN- shares its negative charge approximately equally between sulfur and nitrogen (-S-CN or S=C=N-). As a consequence, thiocyanate can bind either sulfur or nitrogen center. it is an ambidentate ligand. [SCN] can also bridge two (MSCNM) or even three metals. Carbon atom of CO has nonbonding (or weakly anti-bonding) sp-hybridized electron pair which is make bond with metal. And also, the highest occupied molecular orbital (HOMO) of CO shows electron density more in carbon of CO. Due to this reason metal coordinate with C of CO. Metal ......CO bonding explained in below. Carbon monoxide binds to transition metals using \"synergistic * back-bonding.\" The bonding has three components, giving rise to a partial triple bond (in CO). A coordination bond arises from overlap of the nonbonding (or weakly anti-bonding) sp-hybridized electron pair on carbon with a blend of d-, s-, and p-orbitals on the metal. A pair of bonds arises from overlap of filled d-orbitals on the metal with a pair of -antibonding orbitals projecting from the carbon atom of the CO, this back binding requires that the metal have d-electrons, and that the metal is in a relatively low oxidation state (<+2) which makes the back donation process favorable.

3. Photosynthetic organisms produce about 300 x 1015 g of oxygen per year (Holland 1995. If this oxygen accumulated, the oxygen content of the atmosphere would double every 2000 years. Why does this not happen? Is the global system regulated? If so, how is this regulation accomplished? Solution Oxygen is considered as one of the most important gas in the atmosphere .it would have been impossible to imagine life without this gas. The contribution of oxygen to the atmosphere is mainly due to the photosynthetic activity of the plants apart from this the splitting of the hydrogen atoms from water vapor in the atmosphere due to photolysis also contributes to oxygen of the atmosphere to a negligible amount.the oxygen is left behind and the hydrogen escapes. The major contributor of atmospheric oxygen is the photosynthetic activity of the plants but this does not accumulate in the atmosphere as most of it is immediately used up by the respiration process. the maintenance of oxygen levels is one of the classic example of homeostasis . Of the amount of oxygen produced though all of it is immediately used in the respiratory process The net gain of oxygen comes from the burial of organic matter (plant and animal matter ) which reacts with the reducing substances of the earth like iron and is locked as the solid oxides over time. Eventually it would be all used up and equilibrium atmosphere would not contain more oxygen. The continuous photosynthesis and carbon burial keeps the level of oxygen as high as it is and thus homeostasis is maintained ,Where plant photosynthesis acts as the the pump and the rate of burial is equivqlent of the aperture between the reservoir halves..

Why did animal phyla appear so suddenly during the Cambrian explosion? Several variables have been hypothesized to play a role in the sudden appearance of diverse animals during the Cambrian explosion. For example, the \'higher oxygen levels\" hypothesis invokes an environmental trigger and the \"evolution of predation\" hypothesis invokes ecological interactions. Erik Sperling, Andrew Knoll, and colleagues set out to test the hypothesis that these two hypotheses are linked. Could the oxygen atmosphere enable the evolution of predation? Sponges lived in low-oxygen oceans before the Cambrian, and they occur today in both low- oxygen and high-oxygen environments. What aspects of the sponge body plan might have prevented the evolution of predatory sponges in high-oxygen environments? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Effective predators tend to be and they have for detecting prey. Sponges lack, , and as adults.

This project will implement a simple username/password lookup system using hash tables. You should create the Hash Table from scratch. It may be helpful to create a separate class called HashEntry, in which you can store a String username and String password. The Hash Table will store these entries using the username as the key and the password as the value. Create a hash code using the key to determine where the value is stored in the Hash Table. Here is a sample hash method. Feel free to borrow it for your program: privateint calcHashCode(String key) { int mod = key.hashCode() % size; return mod < 0 ? mod + size : mod; } You will be provided with a data file containing comma separated usernames and passwords. Read the data in from the file and put it into the table. Once the table is populated, ask the user to log into the system. If their username and password match the data in the table, alert the user that access has been granted: Login: trevor User trevor not found.

Use whatever info or sources you can find to make the most socieconomically conscious argument for your position and present it to the rest of the taskforce Solution Yes. Money spent on education and educational research is never wasted. Government subsidizes universities with the hope of generating economic growth. It is only because of these subsidies that the prospective researchers and budding educationalists are motivated to go into research and create something new. In the absence of these subsidies, many students and researchers are demotivated because they are unable to arrange for required funds for their research. As a result of this many researchers leave their research in between, which is a big harm to the economy. The government should never doubt money it has spent on education and research because even if 1 out of 10 students are able to create something striking, its benefits will help reap the efforts and money invested in no time..
