What are the protocols in data transfer between CAD systems? Which one is most widely used? What types of data may not be transferred accurately or correctly? Solution Answer- Transferring CAD files electronically is the norm, rather than the exception, for today\'s manufacturing world. In the past, shops relied on blueprints.File translation is a process in which one data format is converted into another. File translators are written independently by each CAD or CAM software company. Some design teams may use several different types of CAD packages to communicate with different teams or complete specific functions. One design model may be exported and imported into several CAD packages before the final file reaches manufacturing. There are numerous file formats on the market today. You can encounter IGES, CADL, DXF, ASCII, NCAL, PAR, PRT, SAT, SUP, STL, X_T, MODEL, the various European and American automotive formats, and other file extensions.The International Standards Organization (ISO) is working with American, European and Asian businesses and government agencies to implement a standard for transferring electronic data, called the International STandard for the Exchange of Product Model Data (STEP).STEP, called Application Protocols (APs), which are built into a common data model. A well-built CAM translator translates all types of files quickly and accurately.

Automated software modernisation is the best solution that is fast, low cost, preserves legacy value and is less risky by comparison to the traditional methodology of a re-write or replacement by packaged ERP. Object Management Groups (OMGs) Model Driven Architecture (MDA) methodology provides an automated model-driven reverse engineering and forward engineering process called Architecture Driven Modernisation (ADM) which has already been successfully adopted by a variety of high proﬁle organisations such as Boeing, U.S. Air Force, Raytheon, EDS, Thales (European Aerospace) and numerous governments worldwide. WORPCLOUD LTD is focused on being an Automated Software Modernisation Expert. We use OMG compliant tools and parsing techniques to extract all system information, business semantics and software artifacts into an XML repository called the Abstract Syntax Tree Metamodel. Next we use MDAs automated transformation procedures to generate new source code of your choice. Manual architecting of the target system are also performed before the transformation thus ensuring; speed, low cost and accuracy of the automated process combined with the flexibility & insight of human analysis. Research reveals that application modernisation and migration budgets are currently very strong, covering between 25% to 71% of most companies IT budgets in 2013/2014. This clearly indicates that application modernisation is one of the most significant issues affecting companies – due to high software maintenance costs, low business flexibility and crippled integration and interoperability. Software modernisation is the sole remedy for these problems and your organisation can make huge savings by modernising.

The replacement of the former, purely mechanical, functionality with mechatronics-based solutions, the introduction of new propulsion technologies, and the connection of cars to their environment are just a few reasons for the continuously increasing electrical and/or electronic system (E/E system) complexity in modern passenger cars. Smart methodologies and techniques have been introduced in system development to cope with these new challenges. A topic that is often neglected is the definition of the interface between the hardware and software subsystems. However, during the development of safety-critical E/E systems, according to the automotive functional safety standard ISO 26262, an unambiguous definition of the hardware-software interface (HSI) has become vital. This paper presents a domain-specific modelling approach for mechatronic systems with an integrated hardware-software interface definition feature. The newly developed model-based domain-specific language is tailored to the needs of mechatronic system engineers and supports the system’s architectural design including the interface definition, with a special focus on safety-criticality.

Present investigation is on process planning using neutral file with format STEP for rotational parts with use of computer. CAE systems involved in every stage of product life cycle mainly uses the product data produced by the CAD systems and integrated manufacturing data produced by CAPP and CAM systems. As the degree of automation and CAD/CAM integration increases, the inclusion of high level information with the product data and its seamless flow in CAD-CAM-CNC chain becomes a necessity. The objective of this work is to develop a Computer Aided Process Planning system for rotational parts using ISO 10303 standard STEP AP224 data exchange file, enabling the inclusion of high level information about the product besides geometry. The developed system aims to incorporate the small and medium sized manufacturing enterprises into the e-manufacturing chain by adopting the NC-code based CNC machine tools without any modification of the controllers.

Advantages and disadvantages Signature recognition 1. Definition 2. Importance 3. Advantages and disadvantages Solution Hand geometry (1) Definition Hand geometry readers measure a user\'s hand along many dimensions and compare those measurements to measurements stored in a file. Hand geometry is a biometric that identifies users by the shape of their hands. Hand geometry is not thought to be as unique as fingerprints, palm veins or irises, fingerprinting, palm veins and iris recognition remain the preferred technology for high-security applications. (2) Importance Hand geometry biometrics is not a new technique. It is first mentioned in the early 70’s of the 20th century and it is older than palm print which is part of dactiloscopy. This technique is widely accepted and the verification includes simple data processing. Hand geometry is an ideal candidate for research and development of new acquisition, preprocessing and verification techniques. (3) Advantages Disadvantages Signature Recognition (1) Definition Biometric identification by automatically scanning a person\'s signature and matching it electronically against a library of own signature. It is a behavioural biometric. It can be operated in two different ways: Static: In this mode, users write their signature on paper, digitize it through an optical scanner or a camera, and the biometric system recognizes the signature analyzing its shape.

Consider the many protein functions. Identify the protein function by a check mark. DNA transcription encoding of genes cell membrane receptors ion channels DNA replication Solution 1. DNA transcription: Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by enzyme RNA polymerase. 2. Encoding of genes: Protein encoding genes, or protein coding sequences are commonly described as structural or regulatory. Structural genes encode enzymes and proteins. So, this is a function of proteins. 3. Cell membrane receptors: Cell surface receptors are integral proteins that bind to external ligand molecule. SO, this is a function of protein. 4. Ion channels: Thy are pore forming membrane proteins whose functions include establishing a resting membrane potential, Shaping action potential and other electrical signals by gating the flow of ions across the cell membrane controlling the flow of ions across secretory and epithelial cells and regulating cell volume.So, this is a function of proteins. 5. DNA replication: The process of DNA replication cannot work if the DNA strand cannot be separated. To separate the DNA strands, proteins are used. So, this is a function of proteins..

a) Briefly describe three key differences between the genomes of prokaryotes and the genomes of multicellular eukaryotes. b) Chromosome inversions can have a major impact on evolutionary processes. Describe how chromosome inversions arise and the effect chromosome inversions have on the process of meiosis. What is the potential evolutionary significance of chromosome inversions? Solution a) Genomes of prokaryotes Genomes of eukaryotes Composed with single nacked, circular DNA. Composed with many linear DNA molecules, number varies from species to species. Chromosome organization is absent. Chromosome organization is present. Introns are absent. Introns are present. Centromeres, telomeres are absent Centromeres, telomeres are present. B) Chromosome inversion: Rearrangement of a chromosome segment. Inversion occurs when a single chromosome undergoes breakage and rearrangement within itself. These are two types includes pericentric inversions include a centromere, while paracentric inversions do not. Effect chromosome inversions have on the process of meiosis: A major or key evolutionary effect of inversions is that they suppress recombination in heterozygotes. This follows from the loss of unbalanced gametes that result from recombination. Large inversions show very low (but still positive) rates of recombination as heterozygotes, which results from double cross-overs and gene conversion, but the rates are orders of magnitude smaller than those in homozygotes. Evolutionary significance: Like other types of mutations, inversions evolve under selection and random drift. Many inversions, particularly small ones in intergenic regions, are likely to evolve neutrally (by drift alone). Selection can result in three ways. Inversions can generate structural problems with meiosis, as with some pericentric inversions. Alternatively, a breakpoint can disrupt an open reading frame or alter gene expression. The consequences can be deleterious, as in some human genetic diseases [6], but in other cases could cause an adaptive mutation. Finally, selection can act on an inversion when it carries one or more selected alleles. Genomes of prokaryotes Genomes of eukaryotes Composed with single nacked, circular DNA. Composed with many linear DNA molecules, number varies from species to species. Chromosome organization is absent. Chromosome organization is present. Introns are absent. Introns are present.

1- An information security manager routinely monitored Web Surfing among her company\'s employees. She discovered that many employees were visiting the \"sinful six\" web sites (Note: The \"sinful six\" are web sites with material related to pornography, gambling, hate, illegal activities, tastelessness and violence.) She then prepared a list of the employees and their surfing histories and gave the list to management. Some managers punished their employees. Some employees, in turn, objected to the monitoring claiming that they should have a right to privacy.With this in mind, please answer the following two questions: a- Is monitoring of web surfing by managers ethical, (it is legal to do this)? -- Support your answer. b- Is employee web surfing on the \"sinful six\" ethical? Support your answers. 2-Discuss the idea that an information system by itself can rarely provide a sustainable competitive advantage. Justify your position. 3- Discuss why the Sarbanes-Oxley Act is having an impact on information security. Support your answer. 4- How are the network applications of communication and collaboration related? Do communication tools also support collaboration? Give Examples. (NOTE: there are two questions that need to be answered in your response. I will be looking to see if both questions are answered accordingly) 5- Explain why master data management is so important in companies that have multiple data sources. Solution Ans 1. a) Yes, monitoring of web surfing is ethical and an important duty of both network administrator and Information Security managers too. Any unethical use of the system can be detected only by scrutinizing the system. Though in the given scenario, some employees think it to be intrusion of their privacy but using organizational resources for their own private uses, and that too surfing pornographic sites, in office hours is completely unethical both professionally and morally. As the company must have female employees too and surfing pornography in front of them has high probability of causing embarrassment to them. Company has provided the computer and internet connection for official works only but using them for own personal use is at all not acceptable. Hence it is the employees’ duty to use office provided computer and internet connection for office works only and not to stray into one of the “sinful six” websites. b) No, it is not ethical on part of the employee to surf sites like “sinful six”. Firstly, the organization must definitely have female employees and surfing pornographic sites will definitely cause embarrassment to them. Secondly, the computer and internet resources provided by the company are for official purpose only. Wasting company resources and time on visiting sites related to pornography, gambling is not ethical for employees. Thirdly, several companies have clearly stated policies on refraining use of official IT resources on visiting sites especially related to pornography or gambling. Hence .

Can a single magnetic pole (either a north pole or a south pole) be isolated? Can it exist by itself? Explain. Can a single charge (either a positive charge or a negative charge) exist by itself? List some sources of magnetic fields. How are they produced? What is the source of Earth\'s magnetic field? How does Earth\'s geographic North Pole correspond to a magnetic south pole? Explain. How do different poles (north and south) interact with each other (e.g. attract or repel). Solution a) single magnetic pole are hypothetical elements; mono poles can not exist ; and it is not possible to either seperate north pole or south pole. Magnetic poles exist always in pairs with north and south on either end , how small you cut a magnet into pieces even into atomic scale you will eventually creating a north and south pole but never a mono pole. b)Mono poles exist in electric field; a single positive charge can exist sperated from a single negative. but the net charge of the universe is alwasy zero ; we can creat positive and neagtive charges in pairs and seperate them individually , such that the existanceof one will not influence the other . but for evey positve charge in this universe there is a negative charge created. c)earth magnetic field is the alwasy present untill there is motion of the hot molten metallic currents at the centre of earth. in general current produces magnetic field ; some of the magnetic sources are hard disk drives have thin magnetic coating; magnetic compass needles and some naturally occuring magnetic materials. earth points its magnetic north to the magnetic south pole ; since earth behaves like a tiny magnet placed in magnetic field of sun. so a tiny magnetic always shows its geographic north to the magnetic south pole when placed near a magnet. d) opposite poles attract and like poles repel ; north repels north and south repels south ; north attracts south and vice versa.

What recent and past actions have Canada and the US taken to counteract their exchange rates with the economy in such distress over the past 10 years? Solution Since 2007, the world has experienced a period of severe financial stress, not seen since the time of the Great Depression. This crisis started with the collapse of the subprime residential mortgage market in the United States and spread to the rest of the world through exposure to U.S. real estate assets, often in the form of complex financial derivatives, and a collapse in global trade. Many countries were significantly affected by these adverse shocks, causing systemic banking crises in a number of countries, despite extraordinary policy interventions. Systemic banking crises are disruptive events not only to financial systems but to the economy as a whole. Such crises are not specific to the recent past or specific countries – almost no country has avoided the experience and some have had multiple banking crises. While the banking crises of the past have differed in terms of underlying causes, triggers, and economic impact, they share many commonalities. Banking crises are often preceded by prolonged periods of high credit growth and are often associated with large imbalances in the balance sheets of the private sector, such as maturity mismatches or exchange rate risk, that ultimately translate into credit risk for the banking sector. Crisis management starts with the containment of liquidity pressures through liquidity support, guarantees on bank liabilities, deposit freezes, or bank holidays. This containment phase is followed by a resolution phase during which typically a broad range of measures (such as capital injections, asset purchases, and guarantees) are taken to restructure banks and reignite economic growth. It is intrinsically difficult to compare the success of crisis resolution policies given differences across countries and time in the size of the initial shock to the financial system, the size of the financial system, the quality of institutions, and the intensity and scope of policy interventions. With this caveat we now compare policy responses during the recent crisis episode with those of the past. The policy responses during the 2007-2009 crises episodes were broadly similar to those used in the past. First, liquidity pressures were contained through liquidity support and guarantees on bank liabilities. Like the crises of the past, during which bank holidays and deposit freezes have rarely been used as containment policies, we have no records of the use of bank holidays during the recent wave of crises, while a deposit freeze was used only in the case of Latvia for deposits in Parex Bank. On the resolution side, a wide array of instruments was used this time, including asset purchases, asset guarantees, and equity injections. All these measures have been used in the past, but this time around they seem to have been put in place quicker (for detailed informatio.
