What is the between facial action unit and facial landmark differences ? Solution There is a difference between the facial action unit and facial landmark. The difference can be illustrated as follows: FACIAL ACTION UNIT: Humans interact far more naturally with each other tahn they do with machines. To approach the naturalness of face-to-face human interaction machines should be able to emulate the way humans communicate with each other. Although speech alone is often sufficient for communicating with another person, non-verbal communicative cues can help to synchronize the dialogue, to signal comprehensionor disagreement and to let the dialogue run smoother, with less interruptions. With facial expresssions we clarify what is said by means of lip-reading, we stress the importance of the spoken message by means of conversational signals like raisisng eyebrows, and siognal comprehension,disagrreement,boredom and intensions. Machine understanding of facial expressions could revolutionize user interfaces including ambient,automotiveand robot interfaces and has become,therefore,a hot topic in computer-vision approach. FACIAL LANDMARK: Localizing facial landmarks (i.e facial alignment) is a fundamental step in facial image analysis. However, the problem is still challenging due to the large variability in pose and appearence, and the existence of occlusions in real-world face images. EGM (Exemplar-based graph matching) framework is used in the facial landmark localization.Compared to conventional algorithms, EGM has three advantages:.

Communication is the key to human success on this planet. The survival of social animals like ourselves would be impossible without the development of ways to exchange ideas and knowledge. Communication is as important for survival in modern days as it was for our cave-dwelling forefathers. Improving communication skills is the modern equivalent of making better flint tools. In this article, we are going to talk about 20 proven ways to Improve Communication Skills.

1. Introduction 1. Technology and communication 1. Technology is changing everything that people used to do in the past 1. Communication can be done to people who are at far distance and technology has changed the lifestyle of the people (Drago, 2015). 1. People are rarely using face to face communication as most of them prefer using social networking sites. 1. Face to face communication enable one to express emotions either through facial expression or tone of the voice. 1. Thesis statement: To discuss reasons as to why face to face communication is better as compared to virtual communication. 1. Body section 1. Benefits of face to face communication 1. When people communicate face to face, it creates a motivation as there is exchange of the words as people are together. 1. It also enables one to see sense on what the other person is thinking about (Carlson, 2017). 1. Face to face communication is crucial in strengthening the bond whether for partnership, friendship and relationship in the workplace. 1. Face to face communication enable an individual to express emotions through either tone of the voice or using facial expression. 1. Disadvantages of virtual communication 1. Technical problems because virtual communication depends on the internet, software and machine and sometimes they have malfunction. 1. Some of the Apps which are used in virtual communication need skills for them to be operated. 1. Virtual communication cannot effectively solve problems which can be addressed by face to face communication (Marlow, Lacerenza & Salas, 2017). 1. Conclusion 1. Face to face communication enables people to express their emotions and motivates people. 1. It also strengthens bond between relationship and partnership. 1. Virtual communication depend on the use of garget and sometimes they fail. .

Cocoon Experience

Undeniably 2020 has been an unpredictable year. This originated some creativity for innovation as much as adaptation and acceleration of existent ideas. Every so often at Cocoon we feel the need to review these technologies and approaches and filter what we feel is relevant for us and our clients into a document that we share internally and externally. This year we gave this document a linear context: Digital Global Humanism. Up until recently people were the central focus in digital businesses and ecosystems. Businesses started by embracing humanism to achieve their results and to enable clients to access their products in the easiest ways possible. But now we also need to remind people about their own responsibility for the Earth. We added this to our process of business transformation.

Journal For Research

Now days, the task of face recognition is widely used application of image analysis as well as pattern recognition. In biometric area of the research, automatically face & face expression recognition attracts researcherÃ¢â‚¬â„¢s interest. For classifying facial expressions into different categories, it is necessary to extract important facial features which contribute in identifying proper and particular expressions. Recognition and classification of human facial expression by computer is an important issue to develop automatic facial expression recognition system in vision community. In this paper the facial expression recognition system is proposed.

Bats rely on sound localization to be able to fly during the night. O.pdf

arshin9

Bats rely on sound localization to be able to fly during the night. On a cool 20 degree C summer night, a bat produces an ultrasonic sound with a frequency of 37 kHz. What is the wavelength of this ultrasound, in meters? While remaining stationary, the bat emits a sound pulse and receives an echo after 0.130 s. How far away, in meters, is the reflecting object from the bat? Solution 1) wave length of ultra sound waves = velocity / frequency = 330/37kHz ( velocity of ultra sound waves in air = 330 m/sec) =.00089189m 2) time taken = .130 distance travelled for the sound pulse = 2*d ( because it is also returing back after strucking the object) v*t=2*d d= 330*.130/2=21.45m.

Discuss the impact that the tonnage of sulfur or sulfuric acid recov.pdf

arshin9

Discuss the impact that the tonnage of sulfur or sulfuric acid recovered from SO2 in flue gas treatment would have upon the chemical industry if all coal- and oil-fired were required to use such treatment processes. Solution YEs, definitely we must required to use FGD as sulfur dioxide enters the air mainly from industrial processes and from the combustion of hydrocarbon fuels with a substantial sulfur (S) content and represents a major source of air pollution. Sulfur dioxide is a colorless, corrosive gas that has a bitter taste, but no smell at low levels. The share of SO2 emissions comes from the use of coal and oil in fossil-fired power plants, in industrial combustion units, in small combustion units in households, and in vehicles. Besides the concentration of SO2 in stack gases emitted by steam generation plants is usually in the range of 800 to 6000 mg/Nm3, the volume of gases produced by the utility industry worldwide results in the liberation of a large tonnage of sulfur dioxide into the atmosphere.Sulfur dioxide is a chemical that can be dangerous in many ways. At lower levels, sulfur dioxide has been found to be a corrosive irritant to eyes and skin. Sulfur dioxide has been associated with a variety of respiratory diseases and increased mortality rates. Inhalation of sulfur dioxide can cause increased airway resistance by constricting lung passages. Sulfur dioxide is also one of the main ingredients in acid rain. Acid rain occurs when sulfur dioxide or other gaseous chemicals, such as nitrogen oxides, are released into the air. These gases ascend through the atmosphere, and when they reach upper cloud levels, they react with water, oxygen, and sunlight.Various concentrations of sulfuric acid and nitric acid are then produced. These acids mix with the condensed water vapor in the clouds and fall to the ground with the water in various forms of precipitation. This precipitation with greater acidity is what is known as acid rain. Acid rain is dangerous to many natural ecosystems; it can harm plants, sand, make water undrinkable, and unlivable for many animals. The biggest producers of sulfur dioxide emissions are electrical utilities that produce electricity through the burning of fossil fuels.Sulfur dioxide emissions, from combustion installations using coal or HFO, can be reduced by fuel desulfurization or by FGD, as well as by a combination of these two measures. Flue gas desulfurization is an efficient method for the reduction of the sulfur dioxide emissions.2 Many processes are available in the market, such as (a) wet scrubbers, (b) spray dry scrubbers, (c) sorbent injection, (d) regenerable processes, and (e) combined SO2/NOX removal processes.

You have decided to go to graduate school for Molecular Biology (yay!.pdf

You have decided to go to graduate school for Molecular Biology (yay!). Your first project involves investigating the regulation of expression of a gene suspected to be involved in the immune response to Zika Virus (we\'ll call this gene ZV1). You have found that this gene is expressed when someone is infected by Zika, but is not expressed in uninfected people. You believe that this is due to a change in a histone modification. Come up with a hypothesis for what type of change in histone modification may be responsible for the expression of this gene upon infection with Zika. Describe, in detail, an experiment to test your hypothesis. Include any necessary controls. Assuming your hypothesis is correct (of course it is), draw the results of the experiment (it doesn\'t have to be perfect, do the best you can). One of your friends in graduate school is super interested in your project. She thinks that there may be an epigenetic component to the expression of this gene in response to Zika Virus other than that of histone modifications. Describe a non-chromatin based mechanism for this and briefly describe how you might test this. Solution Thanks for the question. a. A hypothesis for the mechanism of expression of gene following infection with zika virus is follows the zika virus upon entering the body produces a translation whereby a RNA genome is produced which enters the endosomal membrane of the host cell causing the symptoms of zika virus fever etc b. an elisa test (enzyme linked immuno sorbent assay) which could test either the zika virus or its translated RNA could be a good way of assessing the infection of zika virus. c. A standard can be set up on the number of zika virus or its replicated RNA which is necessary to be present in the body of the infected patient to call him to be actively infected with the virus. This will decide for subsequent patients if they are infected with the virus and also if they are actively carrying the infection. d. the original hypothesis stated above is already having an epigenetic component. Hence its detection and other procedures are already mentioned above. Regards.

The retrovirus genome is made of the nucleic acid before the virus becomes a provirus, in order for that to occur the form of the genome must be converted to Solution 1) Answer: The retrovirus genome is made of the nucleic acid, RNA before the virus become a provirus; in order that to occur, single stranded form of the genome must be converted to double stranded form. Explanation: A retrovirus is a single-stranded RNA virus with a DNA intermediate and, as an obligate parasite, targets a host cell. In most viruses, DNA is transcribed into RNA, and then RNA is translated into protein. However, retroviruses function differently, as their RNA is reverse-transcribed into DNA (by an enzyme reverse transcriptase), which is integrated into the host cell\'s genome (when it becomes a provirus), and then undergoes the usual transcription and translational processes to express the genes carried by the virus. 2) Answer: Human make RNA during a process called transcription. Synthesis of RNA is usually catalyzed by an enzyme—RNA polymerase—using DNA as a template, a process known as transcription..

Significance of Discoveries in Genetics and DNA Our understanding of genetic inheritance and the function of DNA in producing the characteristics of the individual have been developing for more than 150 years. Consider our current state of knowledge. Link genetic characteristics to DNA structure. Explain how DNA through the process of protein synthesis is responsible for the ultimate expression of the characteristics in the organism. Describe how interference in protein synthesis can result in disruption of cellular and bodily processes? How does the significance of one class of proteins, the enzymes, relate? Please answer all questions! Solution 1. Genes are segments of chromosome and correspond to DNA sequence(s). The DNA segment carries coded information for the synthesis of specific proteins which carry out different functions in the cell. The characters are expressed through proteins. DNA is packed into chromosomes. In gametes, the chromosome number is halved. The fusion of gametes in zygotes restores the chromosome number. 2. Segments of DNA called genes carry traits in encoded form. The genes undergo transcription (transfer of information from DNA to RNA). This is followed by translation which is the transfer of information from the RNA to the protein. The characters are expressed through proteins which are specific in function. 3. Various antimicrobial drugs interfere with the process of protein synthesis at the ribosome level. The information encoded in the nucleotides of DNA are expressed through proteins which carry out specific functions in the cell. Disruption of protein synthesis prevents the biochemical pathways and specific functions of proteins. 4. Enzymes are responsible for controlling various vital activities in the cell. They synthesize, deliver and eliminate various chemicals. Enzymes undergo slow depletion which reduces overall strength and viatality of the human body..

Scope is much less complicated if functions cannot contain other func.pdf

arshin9

Scope is much less complicated if functions cannot contain other function definitions (C++, Java: cannot; Ada, Pascal, Ada, Python, Ruby, Lisp: can). Give one good reason why functions should not contain other function definitions. Give one good reason why it should be allowed. Solution A function is the smallest block of code to perform a specific task. Which can be independently invoked. The variable defined in a function are available only to that block not to the whole program which gives abstraction. the scope and life of variable defined in the funciton are available only when it is invoked, which saves memory as well. b. To keep a function isolated. It\'s only used inside the function which is invoked i.e. one place. when it\'s locally used why define globally.It\'s just another way of breaking down a big function into smaller pieces without affecting the global namespace with another function name. Quite often the inner function isn\'t a stand-alone so doesn\'t rightfully belong in the global namespace..
